GENERAL PROJECT DESCRIPTION Review Process: An application for a pipeline must be submitted for any pipeline proposed to be located within unincorporated Garfield County, excluding those on public or municipal lands, which are: 1. Greater than 12 inches in diameter and over 2 miles in length or 2 cumulative miles if separated by municipal or public lands; or 2. Any pipeline that is more than 5 miles in length or 5 cumulative miles if separated by municipal or public lands. The Applicant is proposing to upgrade an existing 4" pipeline from a 4" line to a 6" line to increase the flow through the line. No permit was found for the current pipeline. If approved, this application would be for the entirety of the pipeline in Garfield County and would address the absence of a permit. The overall length of the proposed replacement is 21 -miles, 7 of which are located in Garfield County. The project will cross multiple County Roads, with CR 100 being the most impacted. Staff understands that a portion of the pipeline will be required to bore below a stream. Because of the proximity to the stream, additional floodplain or wetlands permitting may be required. This application will be processed as an Administrative Review for a pipeline, as described in Article 9 of the Land Use and Development Code. The timelines and process are outlined in the attached process flow charts. II.

February 12, 2019 PURPOSE and SCOPE Rocky Mountain Natural Gas, LLC (RMNG), doing business as (d/b/a) Black Hills Energy (BHE), is an intrastate transmission pipeline company whose rates, terms, and conditions of service are regulated by the Colorado Public Utilities Commission (PUC) and its Code of Colorado Regulations, 4 CCR 723-4. RMNG provides gas transportation services to public utilities, natural gas producers, and other transportation customers in Colorado. As such, with this application submittal packet, RMNG is notifying the County of its need to replace an existing 4 -inch steel natural gas transmission pipeline, which extends approximately 21 miles from south of State Highway (SH) 82 on the Waldorf School on the Roaring Fork property in Carbondale, Garfield County up to the Town Border Station (TBS) in the Town of Gypsum, Eagle County. Installed in 1966 (effective installation date December 31, 1966), the existing pipeline currently transports natural gas to end-user customers in the Eagle Valley area, including but not limited to: residents within the towns of Gypsum and Eagle, and the American Gyp -board plant. With the increased growth and development the Eagle Valley is experiencing, RMNG needs to transport additional natural gas to meet the public demand. To do so, RMNG will be installing a new 6 -inch steel transmission pipeline primarily within the existing 4 - inch pipeline right-of-way (ROW) and easement corridor RMNG purchased over 50 years ago from the landowners at that time. Included in the Property Ownership and Authority to File Application section of this application packet are copies of the originally recorded ROW and easement instruments for the entire route of the pipeline segment to be replaced in Garfield County on privately owned parcels. Portions of the 6 -inch pipeline alignment will also be situated within State and County roads ROWs. RMNG will maintain a 3 -ft separation distance between the existing 4 -inch and new 6 -inch pipelines along the alignment corridor. RMNG will be conducting the replacement of the 21 -mile transmission pipeline in phases from 2019 to 2022, in accordance with the System Safety Integrity Rider (SSIR) Plan submitted to the PUC. The overall replacement pipeline segment in Garfield County is approximately 6.379 miles in length, as depicted on the Pipeline Replacement Route in Garfield County Map in AppendixA to this Project Overview narrative, therefore, based on the phasing outlined to the PUC in the SSIR Plan, RMNG's Phase 1 replacement segment will be the first 4.375 miles in Garfield County, extending from the tie-in point to the existing 10 - inch steel natural gas transmission pipeline approximately 3,600 feet west of CR 100 (Catherine Store Road) up to the regulator station at the northeast corner of Panorama Drive and Buck Point Road in the Panorama Ranches Subdivision. Please refer to the Vicinity Map included in the Vicinity Map segment of this submittal packet. Phase 1 replacement construction activities are slated to be conducted between April 15 and November 1 of 2019. The last 2.004 miles in Garfield County will be replaced either in 2021 or 2022. As stated previously, the ROW instruments provided in this application submittal packet covers the entire corridor of the pipeline to be replaced on private lands in Garfield County. However, the primary focus of the alignment sheets and this Project Overview is for Phase 1 and its related work locations and activities. If determined necessary by the County, RMNG will resubmit to County Planning at a future date the information for the remaining length of pipeline replacement within Garfield County once the appropriate design and engineering have been completed for that future phase. Page 3 of 18 Project Overview (Garfield County) Cottonwood Pass 6 -inch Pipeline Replacement Project February 12, 2019 PROJECT DESCRIPTION The approximate 6.379 -mile replacement pipeline alignment in Garfield County, from SH 82 to the Garfield/Eagle countyline, extends primarily through privately owned properties with approximately 7,650 feet of the alignment located within the following road ROWs: Colorado Department of Transportation's SH 82 - 3,600 feet and Garfield County Road and Bridge's county road (CR) ROWs: CR 100 (Catherine Store Road) - 3,870 feet, CR 102 (Missouri Heights Rd) - 60 feet, and CR 170 (Panorama Drive) - 60 feet. All landowners directly affected by the replacement pipeline project in Garfield County have been notified of the work that is slated to occur within RMNG's recorded ROW and easement through their properties between 2019 and 2022. Please refer to the Property Ownership and Authority to File Application section of this application packet for copies of the letters and maps mailed to the landowners along with the copies of received signed certified return receipts. Per the email dated January 23, 2019 from BHE's Associate General Counsel, Douglas Law, RMNG will be exercising their legal right to enter these properties to perform the replacement work based on the language in these recorded instruments. A copy Mr. Law's Limited Position Statement email is included in the Property Ownership and Authority to File Application section of this application packet. NOTE: At the time of Mr. Law's email, RMNG had been planning a different tie -point for the 6 -inch pipeline to the 10 - inch transmission pipeline. However, due to landowners declining to grant RMNG new ROW, RMNG has selected a different tie-in point and route, therefore, the reference to Mr. Gebhardt's property and the corresponding RMNG ROW instruments in Mr. Law's email are no longer applicable. The Jean M. Blue Revocable Trust property with its associated recorded RMNG ROW and easement instrument replaces Mr. Gebhardt's information. Regardless, the position outlined in Mr. Law's email is still applicable to the Jean M. Blue Revocable property. That being said, HRL, on behalf of RMNG, has notified and met with each landowner to document any concerns or stipulations not already addressed by the existing ROW and easement instruments. Unless specified otherwise by the landowner, RMNG and their contractor will replace any items damaged during construction activities with like or better new materials, and will replace all existing fences and posts as well as restore and reclaim all disturbance areas back to pre -construction conditions. Please refer to the Stormwater Management Plan Cottonwood Pass Pipeline, Garfield County, Colorado (dated January 2019 Revision #1), the Revegetation Plan Cottonwood Pass Pipeline, Garfield County, Colorado (dated January 2019), and the Noxious Weed Management Plan Cottonwood Pass Pipeline, Garfield & Eagle Counties, Colorado (dated January 2019) included in the SWMP/Revegetation Plans and Weed Management Plan sections of this submittal packet. Outlined below is a parcel breakdown of the Phase 1 route with the description of the associated work to be performed at each location. Please also refer to Summit Engineering's Alignment Sheets and to the 350 -ft Radius Maps included in the Site Plans/Engineered Plans and the Adjacent Properties sections, respectively, of this submittal packet. Section 32, Township 7S, Range 87W • PIN: 239132200003—Aspen Waldorf Foundation The existing above -ground tie-in of the 4 -inch transmission pipeline to the existing 10 -inch transmission pipeline on the Waldorf School on the Roaring Fork property will be abandoned in place Page 4 of 18 Project Overview (Garfield County) Cottonwood Pass 6 -inch Pipeline Replacement Project February 12, 2019 by being disconnected from the 10 -inch natural gas transmission system with blind flanges and end capped at the end of each constructed phase. This will be a one-time activity at this site. Section 36, Township 7S, Range 88W • PIN: 239129300082 —Jean M. Blue Revocable Trust In lieu of replacing the existing 4 -inch pipeline starting at the Waldorf School on the Roaring Fork property and along its current route through the Blue Creek Subdivision and the new polo field, RMNG will tie-in the 6 -inch replacement steel pipeline to the existing 10 -inch transmission pipeline in the southeast corner of the Blue property within RMNG's existing 50 -ft wide ROW easement (#416871). On this property, approximately 92 feet of new 6 -inch steel pipeline will be installed, via trenching, along with the above -ground appurtenance of a pig launcher. The pig launcher will provide RMNG the means to perform mandated internal testing, maintenance, and reporting of the pipeline to the PUC through the deployment of various devices known as "pigs" (or Pipeline Inspection Gauges), which will perform various maintenance operations within the pipeline without interrupting the flow of natural gas. All activities associated with this type of operation is confined completely within the allotted ROW corridor and conducted annually by two (2) RMNG personnel. ➢ Smart Pigs — or intelligent Inline Inspections (ILI) are high-tech devices that, when deployed, can detect corrosion and anomalies that could cause future leaks and more. These devices are integral to pipeline safety and accident prevention. ➢ Cleaning Pigs — are devices much like the smart pig but without the technology that simply have a brush, scraper or something similar to clean the pipes and remove any sedimentation and buildup that could impede flow. A picture of a pig launcher is provided in Photo 1 below. Photo 1— Pig Launcher Page 5 of 18 Project Overview (Garfield County) Cottonwood Pass 6 -inch Pipeline Replacement Project February 12, 2019 Per the landowner's request, the pig launcher, once installed, will be barricaded off from the pasture, having its own access gate, and will be painted a shadow grey color. Photo 2 below depicts an example of the type of barricade system RMNG would utilize. It is likely RMNG would utilize a 3 -rail barricade rather than the 2 -rail depicted in the photograph. Photo 2 — Barricade Additionally, the landowner has granted RMNG the use of an additional 20 -ft wide by 135 -ft area in the improved pasture as a temporary construction easement. Included in the Property Ownership and Authority to File Application section of this application packet is a copy of the signed Memorandum of Surface Use Agreement (Memo of SUA). The original Memo will be submitted to the Garfield County Clerk and Recorders' office on or before February 19, 2019. To minimize impacts to the pasture along RMNG's 50 -ft wide ROW, RMNG and their contractor will access the work area via CR 103 (driveway access to Western Slope Materials) and along CDOT's permanent easement, a portion of which overlaps RMNG's 50 -ft wide pipeline ROW, on the Blue property. Access over CDOT's permanent easement on the Blue property has been requested in the submitted Utility/Special Use Permit Application packet to CDOT's Grand Junction office.

The Page 8 of 18 Project Overview (Garfield County) Cottonwood Pass 6 -inch Pipeline Replacement Project February 12, 2019 approximate location of the temporary staging area will be situated on the property in an area previously disturbed by Holy Cross Energy. Access to the Staging Area and pipeline ROW will be off of CR 102 (Missouri Heights Rd) via an existing driveway and access gate. The staging area, its uses, and infrastructure are discussed further in Section 9-102(P) below. • CR 102 (Missouri Heights Rd) ROW Approximately 60 feet of pipeline would be installed via boring within the R&B ROW for CR 102 or Missouri Heights Road. Sections 17 and 20, Township 7S, Range 87W • PIN: 239117303010 — Laughing Stock, LLLP Approximately 7,190 feet of pipeline will be replaced within RMNG's 50 -ft wide ROW (#243294) through this property. Access will be off of CR 102 along the pipeline ROW which is situated within the driveway into the Strang Ranch. At the entrance drive from CR 102, RMNG has an existing above- ground regulator station which will remain in place. There is an existing farm tap located close to the Strang residence which will be removed. To restore service to the residence, RMNG and their contractor will also tie-in and extend an existing 2 -inch PE line approximately 2,800 feet in the 6 -inch pipeline trench to the residence. An existing above -ground 4 -inch valve will also be removed and replaced with an above -ground 6 -inch valve set. Per the landowner's request, RMNG and their contractor will be rerouting approximately 2,500 feet around the Strang's ranch headquarters in order to avoid existing structures and corrals, some of which have been constructed within RMNG's ROW and overtop of the existing pipeline. This rerouted segment will be installed in an improved pasture and around the ranch headquarters/building in internal drive lanes and abandoned irrigation ditches. Based on the language of the recorded ROW and Easement instrument (#243294), RMNG's 50 -ft ROW follows the placement of the pipeline. Therefore, under this current easement RMNG will install the new pipeline, including the reroute segment. Upon completion of Phase 1 construction activities, RMNG will contract the services of a surveyor to conduct an as -built survey of the new pipeline. Per the landowner's request, the old ROW instrument will be vacated concurrently with the recording of a new ROW and Easement document describing the 6 -inch pipeline's exact legal description and route through the property.

The permit agency name, permit/action driving task, and the task to be performed to obtain the permit, prior to issuance of the permit by the County. Based on the locations of the proposed route, HRL and RMNG have initiated application processes with the following agencies for their review and approvals: • The Colorado Department of Transportation for the installation of approximately 3,600 feet of 6 - inch steel transmission pipeline within SH 82 ROW; • The Garfield County Road & Bridge Department for the installation of approximately 3,870 feet of pipeline within County road ROWs; and • The Colorado Department of Public Health and Environment (CDPHE) for a General Stormwater Permit (Permit No. COR030000) and the new COR -40000 permit. The intent of RMNG, with the assistance of HRL, is to conduct concurrent review processes with the above- mentioned agencies in order to expedite field work commencing as soon as authorizations are received. It is imperative construction is completed on or before November 1, 2019 to ensure natural gas is delivered to end users during the upcoming winter months For copies of the submitted CDOT and County R&B permit applications, please refer to Appendix 8 and Appendix C of this Project Overview narrative. Air Per Air Quality Control Commission (AQCC) Regulation 3, Part A, Subpart II.D.1.j., an exemption is made for certain land development applications. The exemption from permitting and air pollutant emission notices (APEN) is stated as follows: "Disturbance of surface areas for purposes of land development, that do not exceed twenty-five contiguous acres and that do not exceed six months in duration. (This does not include mining operations or disturbance of contaminated soil)." Therefore, since the pipeline replacement work activities will not exceed 25 contiguous acres of disturbance and no area of disturbance will remain open for greater than 6 months in duration, this project meets the exemption listed in Regulation 3. Stormwater Based on the total amount of proposed disturbed acreage, 133.72 acres for the entire 21 -mile replacement route, a CDPHE General Stormwater Permit for construction activities is required. Currently, the COR030000 permit is available for Stormwater General Permits to be submitted under, however, effective April 1, 2019, a new General Permit (COR -40000) will replace the COR030000 permit. Included in the SWMP/Revegetation Plans section of this submittal packet is a copy of the signed CDPHE Stormwater Permit application that will be submitted to CDPHE on or before February 19, 2019. The primary purpose of this Stormwater General Permit is to notify the CDPHE of proposed construction activities that exceed 1 acre of disturbance. How RMNG will comply with the permit requirements are outlined in the Stormwater Management Plan included in the SWMP/Revegetation Plans section of this Page 11 of 18 Project Overview (Garfield County) Cottonwood Pass 6 -inch Pipeline Replacement Project February 12, 2019 submittal packet. CDPHE's Stormwater permit will remain in effect on this project until such time a uniformed revegetation of 70% cover of pre-existing conditions have been obtained. While the permit is active and to comply with the State's stormwater requirements, stormwater inspections will be conducted on 14 -day and 30 -day intervals depending on construction activity, i.e. current construction or post -construction. All reports completed for each inspection are kept on file in the event of an audit by CDPHE personnel. Also included in this section of the submittal packet is the Revegetation Plan Cottonwood Pass Pipeline, Garfield County, Colorado (dated January 2019), which outlines the revegetation and reclamation standards RMNG and their contractor will implement. During the regular scheduled inspections, the presence of any noxious weeds found will also be documented. Included in the Weed Management Plan section is the Noxious Weed Management Plan Cottonwood Pass Pipeline, Garfield & Eagle Counties, Colorado (dated January 2019), which outlines how noxious weed population will be addressed if found on the ROW after construction activities are completed. Once revegetation has been achieved, a Stormwater Permit Termination application will be submitted to CDPHE.

The general location of the staging areas required for pipeline construction. As noted previously, the staging area would be approximately 100 feet by 200 feet in size on Ziska Childs' property. The perimeter of the area will be temporarily fenced with a 6 -ft chain link fence and will have a 16 -ft access opening (two 8 -ft gates). A temporary construction office trailer, approximately 8 feet by 30 - ft in size, one dumpster, porta-johns, and a 500 -gal fueling cell would be situated within a secondary containment within the Staging Area only during the Phase 1 construction schedule of April to November 2019. The all temporary equipment and machinery will be removed once Phase 1 construction activities are completed and the entire reclaimed back to the landowner's specifications. RMNG's contractor would provide bottled water for construction personnel at the construction trailer. Pressure Testing Section 9-102(Q) Source of Water RMNG estimates approximately 826 barrels (bbls) would be utilized for testing the newly installed pipeline. Water used to hydrostatic test the newly installed pipeline would be purchased through an agreement with the local Garfield County water plant(s) located within Carbondale, Glenwood Springs, or Rifle. Purchased water would be delivered to the site via transport truck and utilized as needed within the hydrostatic process. Should the hydrostatic testing occur in phases, it is the intention to re -use the water from each phase in each corresponding test. Should unforeseen instances occur, preventing the re -use of the water from previous phases, new water would be purchased from the municipality that has agreed to supply the water. Page 14 of 18 Project Overview (Garfield County) Cottonwood Pass 6 -inch Pipeline Replacement Project February 12, 2019 Wastewater Disposal Upon completion of the hydrostatic testing, waste water will be removed from the pipeline, properly characterized, and profiled for disposal to a properly licensed disposal facility in accordance with Environmental Protection Agency (EPA), state, and local county disposal requirements. Characterization of the waste water may include analytical analysis and non -hazardous waste profiling to one of the following: • Local Waste Water Treatment Municipality • Greenleaf Environmental Services (GES) • Evaporation waste water facilities within Colorado or Utah. Waste water may be temporally staged within tanks on-site while waste profiling is completed and approval has been provided to the receiving disposal facility. Waste profiling analysis will be consistent with the waste acceptance criteria (WAC) for the disposal facility as outlined in their facility permits. Upon receiving approval for disposal at one of the facilities mentioned above, waste disposal manifesting will be provided for each load transported off-site and signed copies will be obtained upon completion.

CDOT Form #1233 11116 Cottonwood Pass 6 -inch Natural Gas Transmission Pipeline Project Project Description (CDOT) Ranch ;t Rearing FCFA HonWcwws AssociatiO6 Rocky Mountain Natural Gas LLC (d/b/a Black Hills Energy) IM Black Hills Energy Project Description (CDOT) Cottonwood Pass 6 -inch Pipeline Project February 6, 2019 PRINCIPLES Rocky Mountain Natural Gas, LLC d/b/a Black Hills Energy 721 Mountain View Rd. Rapid City, SD 57702 PROJECT CONTACTS Donald Green — Project Manager (970) 618-1521 CONTRACTORS Engineering Services — Dale Sostrom, Summit Engineering Environmental Services — Anna Smith, HRL Compliance Solutions, Inc (970) 623-1242 Construction — TBD SCOPE Rocky Mountain Natural Gas, LLC (RMNG), doing business as (d/b/a) Black Hills Energy (BHE), is requesting to install approximately 3,600 feet of a new 6 -inch steel natural gas transmission pipeline within the northern right-of-way (ROW) corridor of Colorado Department of Transportation's (CDOT) State Highway (SH) 82 in the Carbondale area. This segment of 6 -inch pipeline is in Phase 1 of a multi- phase pipeline replacement project, extending approximately 21 miles from Carbondale to Gypsum. Phase 1 is slated for construction in 2019. The 6 -inch natural gas transmission pipeline would connect to the existing 10 -inch transmission pipeline within the Jean M. Blue Revocable Trust (Blue) property approximately 900 feet west of Mile Post (MP) 15 and extend east beyond MP 15 an additional 2,700 feet to the intersection of SH 82 and Catherine Store Road (County Road 100). The proposed pipeline would operate at the Maximum Allowable Operating Pressure (MAOP) of 1,000 lbs, same as the existing 10 -inch transmission pipeline. RMNG is also requesting to temporarily use as access, as well as for machinery activities, the existing two -track path over the portion of CDOT's permanent easement on the Blue property located north of SH 82 ROW and east of County Road 103. RMNG's work within CDOT's ROW and easement would occur in the N%NW% of Section 31, Township 7 South, Range 87 West and the NE%NE% of Section 36, Township 7 South, Range 88 West, both in the 6th Principle Meridian (P.M.) in Garfield County, Colorado. NOTE: a portion of RMNG's 50 -ft wide pipeline easement, granted via the recorded Right of Way and Easement instrument (reception # 416871) in September 1990, overlaps CDOT's permanent easement on Blue property. All work related to the installation of the 3,600 feet of transmission pipeline is expected to be conducted within CDOT's northern limits of SH 82 ROW with additional temporary construction activities occurring over CDOT's permanent easement on Blue's property (see attached alignment sheets). The surface disturbance within SH 82 ROW would occur primarily within the mowed area between the edge of pavement and CDOT's wildlife fence at their north ROW limits, and would affect the dirt ramps and diverting fence of two game crossings. Most of the pipeline would be installed in an open trench located Page 2 of 4 Project Description (CDOT) Cottonwood Pass 6 -inch Pipeline Project February 6, 2019 approximately 10 feet from the wildlife fence. One small segment of pipe, approximately 70 feet in length, would be bored beneath the cattle/wildlife guard at the driveway entrance to Sopris Tree and Landscape Supply. The anticipated disturbance along this 3,600 -ft long path would occur within a 28 -ft wide area between the edge of pavement and wildlife fence, equating to approximately 100,800 sq ft or 2.31 acres of disturbance within SH 82 unpaved ROW. The anticipated surface disturbance over CDOT's permanent easement on Blue property would occur within a 900 -ft long by 30 -ft wide (27,000 sq ft or 0.62 ac) area. Therefore, total disturbance within CDOT's ROW and easement is anticipated to not exceed 127,800 sq ft (2.93 ac) in size. REPAIR WORK ACTIVITIES Proposed repair work activities within the designated disturbance areas will consist of: • Temporarily removing wildlife fence, • Excavation and stockpiling of soils, • Installing, cutting, and welding new 6" pipeline, • Installation of new fittings, • Filling in excavated areas, • Repairing wildlife fencing and game crossings (replacing fencing, soil ramps, and diversion fences) • Re -grading and seeding with appropriate weed -free seed mixes. Construction equipment access to these work disturbance areas would occur directly off of SH 82, with temporary lane closures and barricades erected, in accordance with the attached certified Traffic Control Plan. Prior to commencing any digging or ground disturbing activities, Colorado 811 will be contacted to locate all existing utilities within or adjacent to each work area. CONSTRUCTION TIMELINE April 1 to November 1, 2019 As noted previously, this segment of pipeline installation in CDOT's ROW is within the Phase 1 limits of a multi -phase 21 -mile pipeline installation project. It is essential BHE commence and complete all Phase 1 construction activities on or before November 1, 2019 to ensure the continued flow of natural gas to end users during the upcoming winter months.

Per the Garfield County Assessor's database, this property, having the parcel identification number (PIN) 239120300209 is located in Section 20, Township 7S, Range 87W. Enclosed is a map depicting the subject property and the alignment of the existing pipeline. The pipeline replacement work to be conducted and the access to such work areas would occur primarily within the pipeline's existing permanent easement. However, it is very likely additional work areas beyond the easement could be needed temporarily to accommodate construction activities. As a result, BHE, through their appointed representative, would like the opportunity to meet with either you or your presentative to discuss a temporary construction easement through the property, situated in a manner that would be mutually beneficial to both parties. We invite you or your representative to contact either myself at (970) 243-3271 ext 417 or Donald Green at (970) 618-1521 to discuss setting up a time when both parties could meet on this matter.

Per the Garfield County Assessor's database, this property, having the parcel identification number (PIN) 239104300265 is located in Section 4, Township 7S, Range 87W. Enclosed is a map depicting the subject property and the alignment of the existing pipeline. The pipeline replacement work to be conducted and the access to such work areas would occur primarily within the pipeline's existing permanent easement. However, it is very likely additional work areas beyond the easement could be needed temporarily to accommodate construction activities. As a result, BHE, through their appointed representative, would like the opportunity to meet with either you or your presentative to discuss a temporary construction easement through the property, situated in a manner that would be mutually beneficial to both parties.

The Survey shall provide a method or plan for compliance with protection measures and state and federal laws as identified by these agencies pertaining to the identified sensitive areas. This submittal requirement does not apply in previously -disturbed corridors or rights-of-way and/or areas permitted by the COGCC. Per the last sentence of this code section, this submittal requirement does not apply to previously disturbed corridors or rights-of-way. Included in the Property Ownership and Authority to File Application section of this application packet are copies of all the originally recorded ROW and easement instruments for the entire route of the pipeline segment to be replaced in Garfield County. Therefore, RMNG is requesting a waiver of this submittal requirement based on the fact that the 6 -inch pipeline will be placed in the previously disturbed corridors and rights-of-way of the existing 4 -inch and 10 -inch transmission pipelines, in state and county road ROWs, in a hay field, and in internal ranch access road for Phase 1. The rest of the alignment of the replacement pipeline up to the Garfield/Eagle countyline will also be situated within RMNG's existing right-of-way corridor.

This means that all ground surface disturbing activities at the site have been completed, and all disturbed areas have been either built on, paved, or a uniform vegetative cover has been established with an individual plant density of at least 70 percent of pre -disturbance levels. Permit coverage must be maintained until the site is finally stabilized. Even if you are only doing one part of the project, the estimated final stabilization date must be for the overall project. If permit coverage is still required once your part is completed, the permit certification may be transferred or reassigned to a new responsible entity(s).

Title 35, Article 5.5) declares that certain undesirable plants constitute a threat to the "continuous economic and environmental value of lands of the state" and requires that these "noxious weeds" be managed on private and public lands. The Act further declares that control of noxious weeds should use methods that are least damaging to the environment but are also practicable and economically reasonable. The Cottonwood Pipeline Project is located within Garfield and Eagle Counties. Garfield County requires that land owners, persons, or entities leasing the land within the county manage noxious weed infestations on their respective land. Rocky Mountain Natural Gas, LLC (RMNG), doing business as Black Hills Energy (BHE), will be responsible for management of noxious and undesirable species identified on land leased or associated with the project. By implementing a Noxious Weed Management Program, negative economic and environmental impacts will be minimized for RIVING and the surrounding stakeholders. Maintaining control of noxious weed populations within RMNG Right -of -Ways (ROW) is important to keep the cost of noxious weed abatement, stormwater, and revegetation to a minimum. Since the three (3) elements are intertwined, improvement in one (1) area will facilitate improvements in the other areas of concern. It is also vital that the expansion of noxious weeds from the RMNG ROW to private land is monitored closely to ensure weed abatement measures are effective. For the most successful management of noxious weeds, regular communication between RIVING and property owners with adjacent land should be developed. Weed surveys will be conducted along the length of the ROW accordingly. This plan is intended to provide RMNG with a noxious weed management outline for the area of concern, in this instance, the Cottonwood Pass Pipeline Project. The objectives of the plan include: providing basic environmental information about the site, locating and mapping of noxious weed populations, outlining and evaluating possible treatment methods, and establishing preventative measures to minimize noxious weed expansion. This plan will also provide an amendable document for current and future RMNG ROW managers. 2.0 Site Characterization The Cottonwood Pass Pipeline is located in Garfield & Eagle Counties, Colorado. A map of the proposed Right -of -Way (ROW) can be seen in Figure 1. For a comprehensive description of the site's environmental setting, please refer to Appendix A — Noxious Weed Survey Reports. The soil type consists of fifteen (15) general soil units. For more information on soil type, refer to Appendix B and Figure 2. The potential treatment area with regards to noxious and undesirable species will include access roads, and disturbed soils from ROW construction of the Cottonwood Pipeline ROW. 2 3.0 Weeds of Concern To meet the requirements of the Colorado Noxious Weed Act (ACT) and the Garfield County Noxious Weed Management Plan, RMNG shall conduct prescribed management techniques for noxious weed control and prevention. Species warranting prescribed management control and prevention are included within the Colorado Noxious Weed Lists: List A — designated for statewide eradication; List B — managed to prevent further spread and, for selected species, designated for eradication in large areas; and List C — of more localized concern, but for which the State will provide education, research, and biological control assistance to jurisdictions that choose to manage the species. The complete Colorado Noxious Weed List can be found in Appendix C. In addition to the state wide weed list, Garfield County has developed their own noxious weed lists. The county lists are comprised of noxious weeds from the state list that are more specific to the area of concern. Garfield County has designated forty (40) of the eighty-one (81) species from the Colorado Noxious Weed List to be likely species found in the vicinity of their jurisdiction and designated as either need for eradication, containment or suppression. Appendix D contains the Garfield County Weed List and descriptions. Species identified during the 2019 Noxious Weed Survey, prior to any construction activity will be provided below. The survey shall be utilized as the baseline data for management purposes. Noxious Weed Species Observed on the Proposed Cottonwood Pipeline ROW in Garfield County, Colorado Scientific Name Common Name Family State Noxious Weed Garfield County Designation 3 Noxious Weed Species Observed on the Proposed Cottonwood Pipeline ROW in Eagle County, Colorado Scientific Name Common Name Family State Noxious Weed Garfield County Designation 4.0 Weed Inventory Noxious weed surveys will be conducted in the Spring of 2019 along the proposed Cottonwood Pipeline ROW. The pedestrian survey will be conducted on -foot through all areas of the project, documenting all noxious weed species and their extents within the proposed pipeline corridor. A list of all vascular plant species observed on site will be compiled. Field data will be collected with the aid of a Trimble GeoXT data recorder with a GNSS accuracy of 1-100cm, utilizing NAD83 map datum, with all coordinate locations based on the Universal Transverse Mercator (UTM) coordinate system in Zone 13. The full report, will be placed in Appendix A. Additional surveys will be conducted annually by qualified individuals to monitor the success of the noxious weed treatments and document noxious weed populations. Populations of noxious weeds will be mapped by qualified individuals using global positioning units (GPS) units. The surveys will provide a way to identify new noxious weed populations as well as an assessment tool for previously treated populations. The inventory is to be updated as the surveys are performed. There will be an annual review to assess the overall noxious weed populations and success of treatments applied. 5.0 Treatment Methods The treatment methods and descriptions listed below were obtained from the Mesa County Noxious Weed Management Plan (Mesa County, 2008). By integrating RMNG's Noxious Weed Management Plan with Garfield County's Management goals, noxious weed suppression and eradication should be achieved. Management techniques include preventative, cultural, physical/mechanical methods, biological and chemical approaches. Optimal noxious weed management methods will vary with the environmental variables of the area of interest. Soil type and stability, grade, moisture regimes, growing season, pre-existing noxious weed populations, 4 land use, water availability, weed type, stage of growth, as well as the intensity of the infestations should all be considered when preparing a noxious weed management plan. The management methods should have minimal impact on the environment and be economically fitting for implementing the noxious weed management program. When assessing weed management on a property, it is important to evaluate possible modes of transportation for the noxious species. Areas to take into account include; waterways, roads, game trails, areas with livestock and equipment storage sites. The transportation of noxious species is a problem shared by all the stakeholders in the affected area. Good communication should be established between the affected parties for proper management of the noxious weed populations. Most management plans utilize a combination of the treatments outlined below. 5.1 Preventative Methods Preventative methods include practices involving good land stewardship. These practices include, but are not limited to; using weed free certified products, erosion control measures, and regularly cleaning equipment. 5.2 Cultural Methods Cultural methods facilitate competition from desirable plants through actions such as; dense seeding, irrigation, and carefully monitored grazing practices and fertilization. 5.3 Physical and Mechanical Methods Physical and mechanical methods include mowing, disking, hand removal, plowing, burning and solarization. The goal of these methods is predominantly to prevent seed production. Depending on weed species, roots should be severed at least two (2) inches below the soils surface for optimal control. 5.4 Biological Control Methods Biological control methods involve the introduction of living organisms that are deleterious to the noxious weed species. This method is only applicable for infestations larger than five (5) acres in size, and rarely provides complete control of the noxious species. Frequent monitoring must be carried out with this method. 5.5 Chemical Control Chemical control can offer the most effective means of noxious weed control when applied at the appropriate time. Not all herbicides are equally effective against all weeds, nor can every herbicide be used in all settings. The respective herbicide applicator should consult with the Noxious Weed Plan, and pre -construction survey prior to treatment. 5 6.0 Management Strategies Treatment recommendations will vary depending on the species observed and the respective size of the infestation. 6.1 Cottonwood Pass Pipeline Structures It is recommended that the area directly adjacent to structures such as tie-ins and risers be treated with a bare ground herbicide. The bare ground treatment will be applied once a year, or as needed, to a ten (10) foot perimeter around the tie-ins or risers located on the Cottonwood Pass Pipeline ROW. All other areas on the ROW are to be spot treated with an appropriate herbicide. 6.2 ROW and Land Adjacent to the Cottonwood Pass Pipeline Project The respective locations should be treated with a selective herbicide appropriate for the species where the noxious weed is found. The appropriate chemical to be applied will be determined by the licensed herbicide applicator. The specific herbicide applied will vary with the time of year and the stage of growth the plant has obtained at the proposed treatment date. 6.3 Special Requirements At this point in time there are no special requirements for the Cottonwood Pass ROW with regards to management of noxious weeds or other undesirable species. Special requirements will be amended to the document as applicable. 7.0 Management Strategies 7.1 Prevention Taking preventative measures to abate the spread of noxious weeds is critical for proper land management. Noxious weeds can become established on or near disturbed land very rapidly and have the capacity and potential to spread quickly to other areas. Noxious weed seeds and vegetative matter can be transported by means of animals, vehicles, shoes, and straw. Surveys conducted prior to construction will provide RIVING with data of established noxious weed populations on and near the proposed ROW and the possible transport mechanisms on surrounding properties. 7.2 Re -vegetation and Rehabilitation After an area has been successfully eradicated of noxious species, or before establishment has taken place, actions to revegetate the disturbed area will be taken to minimize the chance of noxious weed establishment. If the disturbed land has desired species growing as a result of re - vegetation efforts, competition with noxious species will be increased. Therefore, the potential and capability of the noxious weed to establish in the disturbed area is limited. Noxious weed management strategies for the Cottonwood Pass Pipeline ROW will include a monitoring program. Surveys will be carried out between the months of April and October. 6 Noxious weed populations will be monitored at this point through qualitative visual interpretation as well as mapping. 8.0 Conclusion This noxious weed management plan provides an outline for the treatment and management of noxious weeds. Please refer to Appendix F for the Noxious Weed Summary Documents which provide contact information as well as general information pertaining to the Cottonwood Pass Pipeline ROW. An annual report will be compiled to assess the overall management program. Noxious weed control is critical to guarantee the environment is preserved for future generations to enjoy and utilize. Adhering to this management guide will aid RMNG in managing noxious weeds encountered during the lifetime of the pipeline ROW, and document weed reduction as treatment is applied. These recommendations are not intended to be used as a definitive guide for noxious weed management. Herbicide recommendations are available from the Garfield County Weed Department and/or licensed applicator. 7 9.0 Amendments Please make note of any supplemental information as it becomes available in this section.

The health of our environment is a high priority for residents of Garfield County. The health and productivity of natural plant communities and agricultural lands is threatened by the introduction of numerous invasive alien plants. Without an effective integrated weed management plan these aggressive plants will continue to infest and degrade the lands we value so highly. B. Rapid expansion of noxious weeds is an obstacle to maintaining healthy ecosystems and restoring disturbed native plant communities and habitats. Because noxious weeds tend to be highly invasive and harmful to native vegetation, they can quickly dominate many sites and often cause permanent damage to plant communities. Estimates indicate that 100 million acres of private, state, and federal land are infested with noxious weeds in just 11 western states. This is occurring in both disturbed and relatively undisturbed areas. C. The intent of the Colorado Noxious Weed Act and the goal of the Garfield County Weed Advisory Board is to curb the degradation of our valued environment by implementing an Integrated Weed Management Plan designed to stop the spread of noxious weeds. D. Management of weeds may seem overwhelming, but through developing partnerships at all levels — local, regional and national — we hope to achieve our weed management goals. The challenge for all involved is to develop management systems, support and direction for the prevention of the spread of weeds before the situation becomes even more serious and economically unfeasible. 1.02 Purpose of the Plan A. The purpose of the Plan is to provide guidelines for managing designated noxious weeds which represent a threat to the continued economic, environmental and agricultural value of lands in Garfield County. This plan provides for the implementation of the Colorado Noxious Weed Act by detailing integrated management options for designated noxious weeds. Options include education, preventive measures, good stewardship, and control techniques. B. The intent is to incorporate those options that are the least environmentally damaging and are practical, timely and economically feasible. It is the responsibility of all landowners to use integrated methods to manage noxious weeds, and the responsibility of local governing bodies to ensure that these plants are managed on public and private lands. 1 1.03 Enactment Authority A. The Colorado Weed Management Act (C.R.S. 35-5.5-101) was signed into state law in 1990 and last amended in 2014. Now known as the Colorado Noxious Weed Act, it states that noxious weeds pose a threat to the natural resources of Colorado. B. This plan is designed in accordance with the statutory provisions of the Colorado Noxious Weed Act. The Act directs the Board of County Commissioners (BOCC) of each county to adopt a Noxious Weed Management Plan for all unincorporated land within its jurisdiction. C. Municipalities shall adopt a weed management plan for all lands within their boundaries. The county and municipalities may cooperate, through an intergovernmental agreement, for the powers and authorities of the act. D. The Act directs the Board of County Commissioners to appoint a Weed Advisory Board, whose power and duties are: 1. Develop a noxious weed list. 2. Develop a Weed Management Plan for managing designated noxious weeds. 3. Declare noxious weeds and any state noxious weeds designated by rule to be subject to integrated management. 4. Recommend to the Board of County Commissioners that identified landowners be required to submit an integrated weed management plan for managing designated noxious weeds on their properties. 1.04 Colorado and Garfield County Noxious Weed Lists The Colorado Department of Agriculture's Noxious Weed Program has three noxious weed lists: A, B and C, plus a Watch List. A. Species are assigned to one of three State weed lists through the rule-making authority of the Department of Agriculture. The Commissioner of the Department of Agriculture uses a mandatory administrative process to create the lists, subject to the public notice and publication requirements of the State Administrative Procedure Act. B. The Colorado Noxious Weed Act requires the Commissioner to review and revise the lists at least once every 3 years, using this public process. Updated State weed lists and notices of departmental rule-making are available electronically through the State of Colorado's websites: www.state.co.us; www.ag.state.co.us and www.sos.state.co.us and through the Office of the Garfield County Vegetation Manager. C. State A, B and C Lists. The Colorado Department of Agriculture has determined that "an organized and coordinated effort must be made to stop the spread of noxious weeds." (C.R.S. 35-5.5-102). The rules designate and classify noxious weeds into four categories: 2 1. The State's A list is made up of rare noxious weed species that are subject to eradication, as a matter of law, wherever they are detected in the State, including Garfield County. 2. The B list includes species that have differing distributions throughout the State. Specified populations of B list species are subject to eradication, containment, or suppression in identified areas of the state, including portions of Garfield County. 3. The State's C list includes weed species that are widespread and well-established, for which the State recommends but does not require control, although Garfield County's Weed Management Plan may require control. 4. The Watch List was established in 2011 and is non -regulatory and advisory only. It is designed to increase awareness of new invasive species to the State. D. Garfield County follows the dictates of the State's rules as to which species on the A and B lists must be eradicated, contained or suppressed and manages those species and the species on its own locally -designated list in accordance with the Weed Management Plan contained in the following Sections II -V and the State Department of Agriculture's administrative rules. 1. The County's management plan for species on the State's lists is subject to review every 3 years. 2. The Board of County Commissioners may also adopt a revised Weed Management Plan that includes designated noxious weeds not previously included on any list. E. In addition to the weeds designated on the State's A, B and C lists, the BOCC has the authority to declare plants as noxious weeds if the plant meets one or more statutorily defined criteria (C.R.S. 35-5.5-104 (16), 35-5.5-107, and 35-5.5-108 (3)). 1. The BOCC can also declare those weed species and the weeds on the State's weed lists to be subject to integrated management within unincorporated Garfield County. 2. The County list is subject to change as the State amends the A, B and C lists and as the BOCC declares species not included on the State's list as noxious. F. Garfield County Noxious Weed List as recommended by the Garfield County Weed Advisory Board on February 24, 2014, with Colorado designations listed as A, B or C or NL (Not Listed by the State). The list is current as of adoption of this regulation by the BOCC.

The BOCC has the statutory authority to adopt standards that are more stringent than those set by the State Commissioner of Agriculture. 4 1. The Weed Advisory Board will request such action of the BOCC if and when a species presents a local threat which requires such action. 2. The BOCC also has the authority to apply to the State Commissioner of Agriculture for a Waiver of Compliance if and when the State Department of Agriculture's mandate that a species be eradicated in a portion of or all of Garfield County is deemed unfeasible. 3. If the Commissioner of Agriculture, in consultation with the BOCC, determines that the most cost-effective manner to eradicate designated noxious weeds is for the state to implement an eradication program, the Commissioner may implement such a program through the Department of Agriculture (C.R.S. 35-5.5- 108.5(3)(d)). 5 SECTION II GENERAL INFORMATION 2.01 Definitions Act: The Colorado Noxious Weed Act, Title 35 C.R.S., Article 5.5, as amended.

Xeriscape: Landscaping with water conservation as a major objective. 2.02 Importation and Cultivation of County and State Listed Noxious Weeds. Persons are prohibited from importing seeds, propagating plant parts or live plants and cultivating Garfield County and State of Colorado listed weed species within Garfield County except as provided for in C.R.S. 35-5.5-104.5(a). All listed species are non- native and problematic in Garfield County and the State of Colorado. A. Threat of Escaped Ornamentals. Most plants used for landscaping purposes cannot proliferate outside the cultivated environment of the home garden. Certain exotic plants and seeds were imported to the United States for their aggressive growth habits, xeriscape potential or re -seeding capabilities. 1. The escaped ornamentals include bouncing bet, chicory, cypress spurge, the chamomiles, Dalmatian toadflax, dame's rocket, myrtle spurge, oxeye daisy, purple loosestrife, Russian olive, yellow toadflax. The very traits that make these plants desirable for a garden or landscape may also enable them to thrive outside cultivated areas and become fierce competitors with native vegetation. 2. Because they exist here without the presence of any natural predators, these plants have the ability to spread extensively and pose a severe threat to the delicate balance of our native ecosystems. B. Since various invasive ornamental plants are attractive and establish themselves quickly, they are popular with landscapers and gardeners and may be purchased through certain nurseries in Colorado, in seed catalogues and on the Internet. 1. It is imperative to educate landscape architects, gardeners and nursery growers about the need to eliminate such plants from their landscape plans. Otherwise these plants will inevitably escape from the cultivated garden and jeopardize natural wildflower and plant communities. 2. Native grasses and forbs, as well as agricultural plantings, cannot compete with invasive ornamental plants for nutrients, sunlight and water. As a result, biologically diverse mountain meadows, grasslands, wetlands and agricultural lands are in danger of being overrun by non-native invasive ornamental plants. 2.03 Integrated Weed Management — Treatment Methods An integrated approach to noxious weed management is important because no single technique will be effective. A. Prevention should always be practiced and is effective on all species of weeds. It is accomplished through good land stewardship, planting weed -free seed, avoiding planting invasive weed species, using weed -free seed mulch and erosion control, using clean equipment and taking legal measures such as quarantines and weed laws. 11 1. Cultural management includes methods or management practices which favor the growth of desirable plants over noxious weeds, including maintaining optimum fertility and plant moisture status in an area, planting at optimum density and spatial arrangement in an area, and planting species most suited to a particular area. Techniques include dense seeding, fertilization, mulching, careful irrigation practices, sensible grazing regimes and improved land management practices. 2. Mechanical management methods or practices that physically disrupt plant growth and include tilling, mowing, burning, flooding, mulching, hand-pulling, shoveling, hoeing and chopping. Mechanical methods are most effective for annual and biennial weeds and less effective for perennials. Equipment should be cleaned thoroughly before moving to uninfested areas to prevent the spread of weeds. 3. Biological management involves the use of organisms such as insects and animals to disrupt the growth of noxious weeds. It rarely provides 100% control and must be incorporated with other methods for successful management. Insect species developed to mitigate specific noxious plants are available to the public free of charge from the Colorado Department of Agriculture Conservation Services Division, Biological Control Program, 750 37.8 Rd., Palisade, CO 81526; 866- 324-2963 or 970-464-7916. 4. Herbicide application. It is extremely important to treat small infestation of certain weeds (List A and B species to be eradicated) as soon as possible. Herbicides are most effective when sprayed at specific stages during the life cycle of the weed. To ensure that small infestations of noxious weeds are controlled or eradicated effectively, it is extremely important to take immediate action on certain weed patches. B. The optimum method or methods for weed management will vary depending on a number of site-specific variables: 1. Factors to be considered should include soil type and stability, grade, associated vegetation, existing and proposed land use, proximity to water, availability of irrigation water, weed type and stage of growth and severity of infestation. 2. The management method selected should be the least environmentally damaging, yet practical and reasonable in achieving the desired results. 3. When considering weed management on a property, work on the areas that may transport weed seeds. These areas include ditches, streams, roadsides, driveways, trails, livestock-concentrated areas and equipment storage sites. C. The Colorado Department of Agriculture has prepared fact sheets for most State- listed noxious weeds. They feature detailed descriptions and photographs of the plants, as well as integrated management for each species. (See Appendix A). D. Herbicide application. It is the County's philosophy to minimize the use of herbicides and impacts to desirable vegetation. However, for some species of noxious weeds 12 herbicide application is the only effective method of control. It is extremely important to treat small infestation of certain weeds (List A and B species to be eradicated) as soon as possible. To ensure that small infestations of noxious weeds are controlled or eradicated effectively, it is extremely important to take immediate action on certain weed patches. The County uses hand gun, hand-held or backpack sprayers, utility task vehicles or truck -mounted equipment for selective spot spraying. 1. No Spray Areas. Anyone living adjacent to a County right-of-way who does not want spraying in front of their property can call the Garfield County Vegetation Department and request it be listed as a no -spray property. However, the property owner is responsible for elimination of noxious weeds. Only noxious weeds on the A and B State and County Lists need to be controlled. Land owners must dig up or mow any noxious weeds before they go to seed. If weeds are not properly managed, the County must resume spraying in order to comply with the Colorado Noxious Weed Act (C.R.S 35-5.5-101). Owners of organic farms or who have pesticide -sensitive crops can also call the County to request no -spray listing. Landowners may place "No Spray" signs on their property adjacent to County rights-of-way. Signs should be readable from the roadside and not impact county road maintenance operations. 2. Registry of Pesticide -Sensitive Persons. The registry is maintained by the State of Colorado under the regulatory requirements of the Pesticide Applications Act. Notification to registered individuals must be given in accordance with C.R.S 35- 10-112, and Part 12 of the PAA rules. Pesticide applicators are required to notify registered individuals prior to application of pesticides on adjacent properties. For information about the registry, call the Colorado Department of Agriculture, 303- 239-4146. 3. Source Water Protection. A Source Water Protection Plan was developed in 2013 for community drinking water systems in Garfield County. A current list of systems covered under the Source Water Protection Plan is available through the Garfield County Public Health Department. The plan prioritizes source water protection concerns and identifies local source water management approaches that can be implemented to protect the source of drinking water for these communities. It delineates areas around these communities as source water protection areas. Pesticide application was identified a potential source of water contamination. Garfield County Vegetation Management is committed to using best management practices when applying herbicides to control noxious weeds. These practices include following label directions and selective spot spraying to ensure direct treatment of noxious weeds and protection of native vegetation and water resources. 4. Changes in herbicide registrations occur constantly. The herbicide label is the legal document on herbicide use. Read and follow all directions carefully. The 13 use of an herbicide in a manner not consistent with the label can lead to injury of crops, humans, animals and the environment. 5. Specific chemical recommendations are available from the Garfield County Vegetation Management Department and/or licensed applicators and are not listed in the Plan. Before using any chemical, thoroughly read the label. Any use of an herbicide inconsistent with the label is neither legal nor recommended. E. The optimum method or methods for weed management will vary depending on a number of site-specific variables. Factors to be considered should include soil type and stability, grade, associated vegetation, existing and proposed land use, proximity to water, availability of irrigation water, weed type and stage of growth and severity of infestation. F. The management method selected should be the least environmentally damaging, yet practical and reasonable in achieving the desired results. When considering weed management on a property, work on the areas that may transport weed seeds, including ditches, streams, roadsides, driveways, trails, livestock -concentrated areas and equipment storage sites. 2.04 Cost Share Program Garfield County offers two cost -share programs — the noxious weed cost -share program and the tamarisk/Russian olive program. A. The noxious weed program is a partnership between the three local Conservation Districts based in Glenwood Springs and Garfield County. 1. Applications are reviewed and approved by a review committee of representatives of the Conservation Districts and the Weed Advisory Board. 2. The program provides partial reimbursement to private landowners for noxious weed treatments on lands within Garfield County. For current program information, go to www.mountsopriscd.org, phone 970-945-5495, ext. 105; www.garfield- county.com, phone 970-945-1377, ext. 4305. B. The tamarisk/Russian olive program is administered through the Garfield County Vegetation Management office and is designed to partially assist landowners with management of tamarisk and Russian olive through the coordination of cutting crews and treatment methods. For more information, contact Garfield County Vegetation Management, 970-945-1377, ext. 4305. 14 2.05 Description of Designated Noxious Weeds GARFIELD COUNTY NOXIOUS WEED LIST The Garfield County Weed Advisory Board encourages all county residents to be knowledgeable about noxious weeds.

Cultural Control: The key to removing cutleaf teasel is to eliminate seed production and exhaust seed bank. Chemical Control: Treat spring or fall rosettes. For specific treatments for rangeland and pasture sites, refer to the Colorado Department of Agriculture Fact Sheets — Cutleaf teasel (Appendix A). 22 CYPRESS SPURGE (Euphorbia cyparissias) Description: A member of the Spurge family introduced from Eurasia; an invasive ornamental. Low -growing perennial that overwinters as root and crown tissue. Reproduces from seed. Leaves are stalkless, alternate, narrow and linear to lance -shaped. Flowers are yellowish -green usually turning reddish -green towards maturity. Comments: Leaves and stems emit a milky, toxic sap when broken. Sap is an irritant and may cause dermatitis or rashes. The soil seed reserve is estimated to be at least 8 years. Location: Found in the Crystal Springs area and in landscaping situations in Carbondale and Glenwood Springs. Cultural Control: Chemical Control: The most important consideration is replacing it in nurseries with alternative native or non-invasive cultivated plants. Remove plants before seed is set, in moist conditions. Be sure to wear gloves due to the toxic milky sap. Prevent establishment of new infestations by minimizing disturbance and seed dispersal, while keeping native community healthy. Maintain healthy pastures and avoid over -grazing. Treat at flowering stage. For specific treatments for rangeland and pasture sites, refer to the Colorado Department of Agriculture Fact Sheets — Cypress spurge (Appendix A). DALMATIAN TOADFLAX (Linaria dalmatica) Description: Comments: A member of the Figwort family introduced as an ornamental from Europe. A creeping, aggressive perennial and escaped ornamental with stems from 2 to 4 feet tall. Flowers are snapdragon -shaped, bright yellow, with orange centers; leaves are waxy and heart - shaped. Especially well -adapted to arid sites and can spread rapidly once established. Because of its deep, extensive root system, and heavy seed production, this plant is difficult to manage. 23 Location: Biological Control: Common in Glenwood Springs, Three Mile Creek, Four Mile Creek and one isolated patch up Slaughter Gulch north of Peach Valley. The defoliating moth, Calophasia lunula, has been released on Dalmatian and yellow toadflax. It may defoliate up to 20% of the leaves of the plant. Mecinus janthinus, a stem -boring weevil, is capable of killing a large portion of the above -ground plant by boring into and killing stems where the larvae feed and live. Cultural Control: Reseed disturbed areas adjacent to toadflax infestation with appropriate perennial grasses. Mechanical Control: Repeated mowing 2 to 3 times a year will slow spread and reduce seed production. Chemical Control: Treat at flower stage or in the fall. For specific treatments for rangeland and pasture sites, refer to the Colorado Department of Agriculture Fact Sheets — Dalmatian toadflax (Appendix A). DAME'S ROCKET (Hesperis matronalis) Description: A member of the Mustard family from Eurasia. Biennial or short- lived perennial forb; a prolific seed producer.

Comments: Found most commonly in areas that have moist, well -drained soils and full sun to light shade. Location: No Name and along Midland Avenue in Glenwood Springs. Cultural Control: Locate and remove plants before seeds are allowed to set. The seed bank must be monitored until it is depleted. Check wildflower seed mix to make sure this plant is not included. Prevent the establishment of new infestations by minimizing disturbance and seed dispersal, while keeping native community healthy. Maintain healthy pastures and avoid over -grazing. 24 Chemical Control: Treat when plant is in rosette or bolting stage. For specific treatments for rangeland and pasture sites, refer to the Colorado Department of Agriculture Fact Sheets — Dame's rocket (Appendix A). DIFFUSE KNAPWEED (Centaurea diffusa) Description: A member of the Aster family introduced from Europe. Biennial or short-lived perennial forb; reproduces from seed. Usually produces a single main, multi -branched stem that is 11/2 to 2 feet tall. Flower is white or pink with bracts. Location: The largest infestation in Garfield County is located west of the Riverbend subdivision southeast of New Castle; scattered along Interstate 70 between Rifle and Parachute and south of Glenwood Springs at the Glenwood Airport and old rodeo grounds and Rifle Creek Golf Course. Cultural Control: Reseeding of disturbed sites with fast growing grasses helps prevent diffuse knapweed establishment. Mechanical Control: Biological Control: Chemical Control: Hand -pulling has been effective, if repeated persistently over time. A root -boring weevil, Cyphocleonus achates, weakens plants by destroying the root system. The weevil larvae of Larinus minutus feed within the seedhead and cause defoliation. Apply to spring to early rosette or bolt stage of growth, or fall rosettes. For specific treatments for rangeland and pasture sites, refer to the Colorado Department of Agriculture Fact Sheets — Diffuse knapweed (Appendix A). HOARY CRESS (Cardaria draba) Description: Also known as whitetop. A member of the Mustard family probably introduced from Europe in alfalfa seed. A very competitive, deep-rooted perennial that reproduces by root segments and seed. Grows erect from 10 to 18 inches high and has a grey-white colored leaf. Flowers are white and numerous in compact, flat-topped clusters which give the plant its name. 25 Comments: One of the earliest perennial weeds to emerge in the spring, producing flowers in May or June. Grows in waste places, cultivated fields and pastures, and is capable of vigorous growth. Location: Common in Garfield County. Cultural Control: Mowing or cultivation effectiveness will be increased if other plants like perennial native grasses or alfalfa are seeded in the hoary cress stand as competitors. Maintain range and pasture in good condition. Promote healthy grass growth through proper irrigation and fertilization. Do not over -graze. Mechanical Control: Removal of top growth is somewhat effective. Repeated treatments may reduce seed production and spread. Chemical Control: Treat at the early bud stage. For specific treatments for rangeland and pasture sites, refer to the Colorado Department of Agriculture Fact Sheets — Hoary cress (Appendix A). HOUNDSTONGUE (Cynoglossum officinale) Description: A member of the Borage family introduced from Europe. Biennial. Prolific seed producer. Grows 11/2 to 3 feet high with reddish - purple flowers. Basal leaves resemble a dog's tongue in shape. Comments: Its small nutlets attach to and are rapidly spread by people, domestic animals, wildlife and vehicles. Grows on ranges, pastures, trails and roadsides and is toxic to horses and cattle, as it contains alkaloids that may cause liver cells to stop reproducing. Location: Widespread throughout Garfield County. Cultural Control: Reseed disturbed sites with fast-growing native grasses. Maintain range and pasture in good condition. Promote healthy grass growth through proper irrigation and fertilization. Do not over -graze. Mechanical Control: Physical removal of the plant at flowering or in early seed formation, by pulling or digging, will break the cycle of the plant. 26 Chemical Control: Treat in spring or fall rosettes. For specific treatments for rangeland and pasture sites, refer to the Colorado Department of Agriculture Fact Sheets — Houndstongue (Appendix A). JOINTED GOATGRASS (Aegilops cylindrica) Description: A member of the Grass family, Barley tribe. A non-native grass introduced from Turkey. Winter annual, reproduces from seed. Grows 15 to 30 inches tall in erect stems which branch at the base to give the plant a tufted appearance. Comments: Location: Cultural Control: Established in many winter wheat -growing areas of North America. The seeds are very similar in size and shape to wheat seed and therefore are difficult to screen out. Found along roadsides, in waste areas, fields and pastures. Found in the Harvey Gap area, in West Mamm Creek, in fields adjacent to Parachute Creek, in scattered locations along county roadsides in the Silt and New Castle areas, and in Wallace and Spring Creeks. The key to control is to prevent the grass from becoming established in fields by cleaning equipment. Plant competitive native grasses. Mechanical Control: Tillage can be effective when plants are in the seeding stage. The main goal is to prevent seed production and spread. Chemical Control: Treat in early spring, late summer, or early fall when the plant is germinating, to prevent seed production. For specific treatments for rangeland and pasture sites, refer to the Colorado Department of Agriculture Fact Sheets — Jointed goatgrass (Appendix A). LEAFY SPURGE (Euphorbia esula) Description: A member of the Spurge family, introduced from Europe. A creeping perennial that grows up to 3 feet tall and reproduces by vigorous root stalks and seed. Roots can extend as deep as 30 feet from a plant that grows 1 to 3 feet tall, with pale green shoots and small yellow -green flowers. 27 Comments: Location: The plant, including the root, has milky latex that is damaging to eyes and sensitive skin. Extremely difficult to control because of its extensive sprouting root. Adapted to a wide variety of Colorado habitats and very competitive with other plants species. If it becomes established in rangeland, pasture and riparian sites, it may exclude all other vegetation due to its competitive nature. Primarily found in Wallace and Spring Creeks in western Garfield County. Individual plants have been located throughout Garfield County. Biological Control: Sheep or goats will graze leafy spurge. If livestock graze it after seed formation, hold animals in a corral for at least 7 days before moving them to an uninfested area to avoid seed spread. Cultural Control: Several flea beetles, Apthona spp., produce larvae that bore into roots and the adults feed on the leaves. Oberea erythrocephala, a stem and root crown -mining, long -horned beetle, and Spurgia esulae, a shoot tip gall midge, are also available. The leafy spurge hawk moth, Hyles euphorbiae, deposits its eggs which then consume the leaves and bracts of the plant. Any activity that encourages vigorous grass growth is very important. Over -grazing stresses grasses and makes them less competitive to leafy spurge. Mechanical Control: Mowing leafy spurge at 14 to 21 -day intervals may cause higher susceptibility to fall -applied herbicides. Chemical Control: Treat after full bloom or in the fall. For specific treatments for rangeland and pasture sites, refer to the Colorado Department of Agriculture Fact Sheets — Leafy spurge (Appendix A). MAYWEED CHAMOMILE (Anthemis cotula) Description: A member of the Sunflower family introduced from Europe. A bushy annual that reproduces prolifically from seed. Mature plants are one-half to 2 feet tall with finely dissected alternate leaf structures. White ray flowers. 28 Comments: Each plant is capable of producing 960,000 seeds that are viable for up to 6 years. The most distinguishing feature is the unpleasant odor it emits. Most commonly found in a wide range of soils but prefers moist poorly -drained soils. Increases in abundance in years of above-average precipitation. Can cause skin rashes, blistering of livestock muzzles, and irritation to the mucous membranes of grazing livestock. Can impart a strong flavor to the milk of dairy animals. Location: While rare, may be found in Beaver Creek and throughout the County in small numbers. Cultural Control: Chemical Control: Prevent establishment of new infestations by minimizing disturbance and seed dispersal, while keeping native community healthy. Maintain healthy pastures and avoid over -grazing. Mowing is an effective method before the seed is set. Perennial grasses should be reseeded for several years. Seed bank must be monitored for 4 to 6 years. Treat from rosette to bolting stage. For specific treatments for rangeland and pasture sites, refer to the Colorado Department of Agriculture Fact Sheets — Mayweed chamomile (Appendix A). MEADOW KNAPWEED (Centaurea nigrescens) Description: A member of the Sunflower family introduced from Europe as a forage species. Perennial. Reproduces from seed. Pink to purple flower heads that are solitary at the tips of branches. Grows 20 to 40 inches with many branches. Leaves up to 6 inches long and 1 inch wide. Comments: When disturbed, has the ability to re -sprout from root and crown fragments. Found most commonly in moist sites, irrigated pastures, moist meadows, river banks, streams, irrigation ditches, roadsides and openings in forested area. Location: Found in the upper Dry Hollow area south of Silt. 29 Cultural Control: Chemical Control: Prevent the establishment of new infestations by minimizing disturbance and seed dispersal, while keeping native community healthy. Maintain healthy pastures and avoid over -grazing. Since meadow knapweed has only been found in small quantities in Colorado, preventing populations from spreading is the most important consideration. Eradication requires intensive work to eliminate seed dispersal and deplete the seed bank. An integrated management plan utilizing hand -pulling, herbicides and cultural remediation is the most effective method. Treat in spring to early summer during bolting to bud growth stages or in fall. For specific treatments for rangeland and pasture sites, refer to the Colorado Department of Agriculture Fact Sheets — Meadow knapweed (Appendix A). MEDITERRANEAN SAGE (Salvia aethiopsis) Description: A member of the Mint family introduced from northern Africa. Biennial or shot -lived perennial. Reproduces from seed. Very hairy rosette of leaves during both the first and second years. During the second year the plant bolts and sends up stems that end in white to yellowish -white flower clusters. Flowers will eventually form 4 nutlets with dark veins. Comments: Location: Cultural Control: When crushed, the leaves have a pungent odor. Most commonly found on rangeland but will invade riparian areas, forests, roadsides and dry pastures. Prefers south -facing slopes in loose, gravelly, well -drained soils. Once established, has the capability to adapt to numerous conditions and form dense monocultures. In the fall of the second year, the stem breaks off and forms a tumbleweed, dispersing 100,000 seeds. Unpalatable to livestock. The only known County location is on the south -facing slope surrounding the No Name Tunnel on Interstate 70 and along the Colorado River bikepath. Prevent establishment of new infestations by minimizing disturbance and seed dispersal while keeping native community healthy. Maintain healthy pastures and avoid over -grazing. Hand pull or shovel when soil is moist, before flowering, and turn over 30 Chemical Control: to dry out. If flowering, collect specimens and bag them carefully to collect all seeds. Seed bank must be monitored for years. Sites must be monitored for 10 years after plant is eradicated. Apply in spring during rosette to bolting growth stages. For specific treatments for rangeland and pasture sites, refer to the Colorado Department of Agriculture Fact Sheets — Mediterranean sage (Appendix A). MUSK THISTLE (Carduus nutans) Description: A member of the Aster family introduced from Eurasia. A winter annual or biennial; reproduces from seed. First year growth is a large, compact rosette from a large, fleshy, corky taproot. Second year stem is erect, spiny, 2 to 6 feet tall and branched at the top. Waxy leaves dark green with light green midrib and mostly white margins; flowers purple or occasionally white. Comments: Commonly found in pastures, roadsides and waste places. Prefers moist bottomland soil, but can also be found on drier uplands. Location: Scattered throughout the County; heaviest in the Crystal River Valley. Cultural Control: Musk thistle, like other biennial thistles, thrives on disturbance. The best management is to minimize disturbance. If it does occur, be certain to revegetate with competitive grasses. Biological Control: Chemical Control: A weevil, Trichosirocalus horridus, attacks the crown area of the rosettes and weakens the plant before it bolts. This weevil has reduced stand density in areas where it has become well established. Treat rosettes in spring or fall. For specific treatments for rangeland and pasture sites, refer to the Colorado Department of Agriculture Fact Sheets — Musk thistle (Appendix A). 31 MYRTLE SPURGE (Euphorbia myrsinites) Description: A member of the Spurge family introduced from Eurasia as an ornamental. Perennial. Reproduces from seed. Capable of projecting seeds up to 15 feet. Blue-green waxy leaves. Plants emit a toxic milky latex when stems are broken. Flowers yellow -green petal -like bracts that appear from March to May. Comments: Location: A popular plant in xeriscapes and rock gardens. Prefers sunny to partly sunny areas in well -drained soils. Poisonous if ingested; milky sap causes blisters upon contact. Most important consideration is replacing it in nurseries with alternative native or non-invasive cultivated plants. Remove plants before seed is set, in moist conditions. Fairly common in Glenwood Springs and Battlement Mesa. Isolated patches have been found in Westbank, Peach Valley and New Castle. Cultural Control: Area must be monitored for 9 years after last flowering plant is eradicated. Prevent the establishment of new infestation by minimizing disturbance and seed dispersal, while keeping native community healthy. Maintain healthy pastures and avoid over- grazing. Mechanical Control: Hand pull or dig when soil is moist. Make certain to pull all the roots and wear rubber gloves and eye protection to protect yourself from the toxic milky sap. Treatment follow-up is important to check root fragment re -sprouts that will occur when the taproot is not completely removed. Chemical Control: Treat at flowering stage in spring or fall regrowth. For specific treatments for rangeland and pasture sites, refer to the Colorado Department of Agriculture Fact Sheets — Myrtle spurge (Appendix A). OXEYE DAISY (Chrysanthemum leucanthemum) Description: A member of the Aster family; a native of Eurasia. Rhizomatous perennial, escaped ornamental. White ray and yellow disk flowers, which bloom from June through August. 32 Comments: Location: Mechanical Control: Chemical Control: Education: Commonly sold in wildflower seed mixes or transplanted as an ornamental despite its tendency to crowd out more desirable vegetation. A rapidly spreading weed in Garfield County on the increase along Main Elk Creek, East Elk Creek, Canyon Creek, Crystal Springs, Missouri Heights and Four Mile Creek. Hand pull or dig when soil is moist. Treat at flowering stage. For specific treatments for rangeland and pasture sites, refer to the Colorado Department of Agriculture Fact Sheets — Oxeye daisy (Appendix A). The key to oxeye daisy management is to create an awareness among homeowners, nurseries, landscapers and landscape architects that oxeye is a noxious weed and therefore should not be specified in plantings, sold in nurseries or planted in home gardens or large-scale landscape projects. PERENNIAL PEPPERWEED (Lepidium latifolium) Description: A member of the Mustard family introduced from southern Europe and western Asia as a contaminant in sugar beet seed. Perennial. Reproduces from seed, roots and shoots. One to over 3 feet in height and has waxy leaves with a white midrib. White flowers in dense round clusters at branch tips. Comments: Can grow in a variety of habitats but frequently found in moist soils such as riparian areas, wetlands, marshes, irrigation ditches, canals and floodplains. Alters ecosystems by acting as a "salt pump," pulling salts from deep in the soil and excreting them on the surface. Change in soil pH alters biodiversity drastically and deceases agriculture and pasture production. Extremely invasive. The best method is prevention. In order to control this plant intensive use of herbicides and revegetation must be utilized. Location: Scattered throughout central to western Garfield County, with the largest infestation found along Parachute Creek. 33 Cultural Control: Prolonged spring flooding of new growth will kill pepperweed. Reestablishment of native and desired plants can take years. Re - plantings must be repeated. Chemical Control: Apply when plant is in bolting to early flower growth stage. For specific treatments for rangeland and pasture sites, refer to the Colorado Department of Agriculture Fact Sheets — Perennial pepperweed (Appendix A). PLUMELESS THISTLE (Carduus acanthoides) Description: A member of the Aster family introduced from Eurasia. Winter annual or biennial; prolific seed producer. Distinguished from musk thistle by smaller flowers from '/2 to 1 inch in diameter. Leaves lack prominent white margin present on musk thistle leaves. May grow to 5 feet or more. Flowers reddish -purple, either solitary or clustered. Comments: Location: Biological Control: Cultural Control: Mechanical Control: Found in pastures, river valleys and along roadsides. Common in southern Garfield County; rapidly spreading south of Battlement Mesa. A weevil, Trichosirocalus horridus, attacks the crown area of rosettes and weakens the plant before it bolts. This weevil has reduced stand density in areas where it has become well established. Like other biennial thistles, it thrives on disturbance. The best management is to minimize disturbance and revegetate with competitive species. Mowing is generally not effective due to the plant's capacity for rapid regrowth. Hand cutting is not effective unless there are repeated follow-up treatments and should only be conducted if there is a commitment to follow-up efforts. Plumeless tends to branch out where it is cut and then re -flowers. Pulling can be very effective, especially after a light rain. Hand -pulling with a good set 34 Chemical Control: of gloves is preferable to shoveling which disturbs the ground creating a potential seedbed for future infestations. Treat rosettes in spring or fall. For specific treatments for rangeland and pasture sites, refer to the Colorado Department of Agriculture Fact Sheets — Plumeless thistle (Appendix A). POISON HEMLOCK (Conium maculatum) Description: A member of the Parsley family. A biennial forb native to Europe. Grows 4 to 10 feet tall. Has white flowers in an umbrella -like cluster. Leaves are shiny green and finely divided, with a musty odor. Comments: Seeds may remain viable in soil for about 3 years. All parts of the plants are highly poisonous. Found along streams, ditch banks and pasture borders. Highly poisonous. Location: Garfield and Baldy Creeks. Cultural Control: The key to control is containment and prevention. Pulling the taproot when the soil is moist can be effective. When the plants are present, the use of herbicides is critical. Biological Control: Larvae of the hemlock moth, Agonopterix alstroemericana, feed on the leaves, stem, flowers and seeds causing severe defoliation and death of the plant. Mechanical Control: Deplete root reserves and reduce seed production with repeated mowing. Chemical Control: Treat in early spring. For specific treatments for rangeland and pasture sites, refer to the Colorado Department of Agriculture Fact Sheets — Poison hemlock (Appendix A). PURPLE LOOSESTRIFE (Lythrum salicaria) Description: A member of the Loosestrife family introduced from Europe; an escaped ornamental. Prolific seed producer, able to produce over 35 Comments: 10,000 seeds per square yard. Erect, square stem; can reach 11/2 to 8 feet tall. Magenta -colored flowers. Highly aggressive invader species found in most wetland sites throughout the state. If left unchecked, a wetland will eventually become a monoculture of loosestrife, posing a severe threat to waterfowl habitat and impeding water flow in irrigation ditches. Location: Tara Park in Silt and the Westbank subdivision in Glenwood Springs. Mechanical Control: Include hand -pulling, mowing and flooding. Hand -pulling is effective only on small plants, when infestations are detected early. The root system must be completely removed, since the root sections can sprout and form new plants. Chemical Control: Cut and properly dispose of flower heads before chemical treatment. Treat in summer For specific treatments for rangeland and pasture sites, refer to the Colorado Department of Agriculture Fact Sheets — Purple loosestrife (Appendix A). RUSSIAN KNAPWEED (Acroptilon repens) Description: A member of the Aster family introduced from Europe. Perennial that reproduces from seed with an extensive underground root system. Ridged stems are stiff and 1 to 3 feet high, with thistle -like flowers that are lavender to white. Comments: Very difficult to control or eradicate once it becomes established. Grows in cultivated fields, along ditch banks, fence rows, roadsides and in waste places. Toxic to horses, and will cause death if consumed over a period of time. Location: Very common in Garfield County; most common in Dry Hollow, Silt Mesa and Missouri Heights. Cultural Control: A single control strategy such as mowing or an herbicide usually is not sufficient. Tends to form monocultures by eliminating other plants. Sowing desirable plant species is necessary after the weed is controlled. Research indicates that the native grasses, 36 streambank wheatgrass and thick -spike wheatgrass will establish in an area after Russian knapweed is suppressed with herbicides. If the stand is not too old and grasses are still present, stimulating grass growth by irrigation, where possible, should increase grass competition with knapweed and keep it under continual stress. Mechanical Control: Repeated mowing combined with herbicide applications will gradually stress the plant. Chemical Control: Treat in spring to bud stage or to dormant plants in fall after the first freeze. For specific treatments for rangeland and pasture sites, refer to the Colorado Department of Agriculture Fact Sheets — Russian knapweed (Appendix A). RUSSIAN OLIVE (Elaeagnus angustifolia) Description: Member of the Oleaster family. A hardy, fast-growing tree from Europe, Russian olive has been promoted for windrow and ornamental plantings. Many reach heights from 10 to 25 feet. Trunks and branches armed with 1 to 2 inch woody thorns. Leaves covered with small scales which give the foliage a distinctive silvery appearance. Fruit berry -like and silvery when first formed but turns brown at maturity. Comments: Once imported as a wind -break, it has spread to riparian areas throughout the County where it is becoming the dominant plant. It has invaded cottonwood areas along streams, and impacted wildlife and bird habitat. Location: Very common along the Colorado River and other drainages especially between Silt and Rifle in western Garfield County. Cultural Control: Plant native trees or less aggressive introduced trees. In riparian areas, establish native riparian vegetation. Mechanical Control: Small trees may be controlled mechanically by using an appropriate tool or shovel. Chemical Control: Treatments include cut -stump, foliar or basal bark. Timing varies; avoid late spring and early summer during heavy sap flow. For 37 specific treatments for rangeland and pasture sites, refer to the Colorado Department of Agriculture Fact Sheets — Russian olive (Appendix A). SALT CEDAR (Tamarix ramosissima, Tamarix parviflora) Description: A member of the Tamarisk family. Deciduous or evergreen shrub or small tree, 5 to 25 feet tall. Comments: May live 50 to 100 years. Tolerance to saline and alkaline soil and water. Copes with high concentrations of dissolved solids by absorbing them through its roots and excreting salts through glands in its stem and leaves which eventually form a saline crust on the soil. A single plant of salt cedar will use about 200 gallons of water a day while it is actively growing. Leaves small and scale -like, on highly branched slender stems. Ramosissima flowers are 5 -petaled and pink to white; Parviflora flowers are 4 -petaled. Location: Widespread throughout Garfield County in riparian areas. Biological Control: Tamarisk leaf beetle, Diorhabda carinulata, has been released along the mainstem of the Colorado River in western Garfield County and some tributaries, and is now established. Adult and larvae cause defoliation. Cultural Control: Establish native riparian vegetation. Mechanical Control: Historically, salt cedar management projects have included root plowing and raking, dozing, mowing and prescribed burning. These methods provide only short-term benefits and are labor intensive. Chemical Control: Treatments include cut -stump, foliar or basal bark Timing varies; avoid late spring and early summer during heavy sap flow. For specific treatments for rangeland and pasture sites, refer to the Colorado Department of Agriculture Fact Sheets — Salt cedar (Appendix A). 38 SCENTLESS CHAMOMILE (Tripleurospernum perforata) Description: A member of the Sunflower family introduced from Europe. Annual, biennial or short-lived perennial forb; reproduces by seed. Flowers are daisy -like with 1 yellow centered flower with white petals for every stem. Leaves are alternate, finely divided, fernlike, odorless when crushed. Stems can grow 3 to 6 feet tall. Location: While rare, may be found throughout the County in small numbers. Comments: Scentless chamomile is most commonly found in moist areas such as hayfields, pastures, roadsides, stream banks, fence lines and drainages. A single plant can produce 300,000 seeds. Has the potential to be devastating in agricultural settings because it causes blistering on livestock muzzles and irritation to mucous membranes. Cultural Control: Chemical Control: Any practice that aids in the establishment of forage into a firm moist seedbed will help reduce growth. Integrated management is the most effective method for controlling scentless chamomile. A combination of tillage, herbicide and competitive cropping can be very effective in preventing seed production and crowding out infestations. Treat in rosette or bolting stage. For specific treatments for rangeland and pasture sites, refer to the Colorado Department of Agriculture Fact Sheets — Scentless chamomile (Appendix A). SCOTCH THISTLE (Onopordum acanthium) Description: A member of the Aster family introduced from Europe or eastern Asia. A biennial that can reach a height of 8 feet. Rosette forms the first year and can have leaves up to 2 feet long and 1 foot wide. The second year the plant produces flowers that are reddish -purple to violet. Comments: Found primarily along roadsides and railroads, but can become an impassable obstacle to livestock on rangeland and pastures. Location: Common in the County. The worst infestations are located between Glenwood Springs and New Castle. 39 Cultural Control: Mechanical Control: Chemical Control: Reseed disturbed sites with appropriate perennial grasses. Digging the plant at the rosette stage is effective. Treat rosettes in spring or fall. For specific treatments for rangeland and pasture sites, refer to the Colorado Department of Agriculture Fact Sheets — Scotch thistle (Appendix A). SPOTTED KNAPWEED (Centaurea stoebe) Description: A member of the Aster family, native to central Europe. Short- lived, non -creeping perennial that reproduces from seed and forms a new shoot each year from a taproot. One or more shoots up to 4 feet tall. Flowers lavender to purple. Comments: Location: Biological Control: Cultural Control: Occupies dry meadows, pastures, stony hills, roadsides and the sandy or gravel flood plains of streams and rivers, where soils are light textured, well -drained and receive summer precipitation. Tolerates dry conditions similar to diffuse knapweed, but will survive in higher moisture areas as well. One of the most invasive, aggressive weeds to plague the western United States. Scattered, isolated patches are increasing in the County. A large infestation is located just west of the Riverbend subdivision southeast of New Castle. Also North Dry Fork northwest of DeBeque, the East Divide area, Cardiff area south of Glenwood Springs, and Battlement Creek. A root -boring weevil, Cyphocleonus achates, weakens plants by destroying the root system. The weevil larvae of Larianus minutus feed within the seedhead and cause defoliation. If desirable grass competition is evident in spotted knapweed stands, judicious herbicide application that does not injure grasses may release them to compete effectively with the weeds. Irrigation may help stimulate grass competition in these cases. Seeding suitable perennial grasses is necessary to prevent weed reinvasion. 40 Chemical Control: Treat spring or fall rosettes. For specific treatments for rangeland and pasture sites, refer to the Colorado Department of Agriculture Fact Sheets — Spotted knapweed (Appendix A). SULFUR CINQUEFOIL (Potentilla recta) Description: A member of the Rose family introduced from Eurasia. Perennial, reproduces from seed. Leaves are palmately compound with 5 to 7 toothed leaflets. Flowers light yellow with 5 petals, seeds are coated with a net -like pattern. Comments: Most commonly found in disturbed areas such as roadsides and pastures. Prefers dry, sandy, gravelly and rocky soils that receive 13 to 50 inches of annual precipitation. Unpalatable to livestock due to a high concentration of phenolic tannins. Can live for 20 years. Location: Found in South Canyon. Cultural Control: Small infestations can be controlled by hand pulling while larger infestations are commonly controlled with herbicides. Re - vegetation should focus on improving the competitiveness of native communities. Increasing the competitiveness of native communities can prevent the establishment of sulfur cinquefoil. As with all weeds, disturbance and bare ground should be avoided. Chemical Control: Treat anytime during the growing season. For specific treatments for rangeland and pasture sites, refer to the Colorado Department of Agriculture Fact Sheets — Sulfur cinquefoil (Appendix A). YELLOW STARTHISTLE (Centaurea solstitialis) Description: A member of the Aster family introduced from Europe. Annual; prolific seed producer. Grows two to 3 feet tall. Flowers are yellow, located singly on ends of branches, armed with sharp straw-colored thorns up to 3/4 inches long. Comments; In California alone, this plant has infested more than 20 million acres. "Chewing disease" results when horses are forced to eat yellow starthistle. 41 Location: Biological Control: Cultural Control: Mechanical Control: Chemical Control: No known infestations in the County, however there have been reports in the past of single plant infestations. A seed -feeding beetle, Bangasterus orientalis, has been released in California and Idaho. Seed weevils and seed flies have also been released. Vigorous competitive grass is essential to maintain a plant community's resistance to starthistle invasion. Mowing or cutting is rarely effective. Treat during rosette growth stage. For specific treatments for rangeland and pasture sites, refer to the Colorado Department of Agriculture Fact Sheets — Yellow starthistle (Appendix A). YELLOW TOADFLAX (Linaria vulgaris) Description: A member of the Figwort family sometimes called common toadflax or "Butter and Eggs." Introduced from Europe. Escaped ornamental perennial reproducing by seed and rootstalk. Flowers bright yellow with deep orange centers that resemble the snapdragon. Comment: Has now become a serious problem to rangelands and mountain meadows. Does well in all types of soils. Its displacement of desirable grasses not only reduces ecological diversity, but also reduces rangeland value and can lead to erosion problems. Because of its early vigorous growth, extensive underground root system and effective seed dispersal methods, yellow toadflax is difficult to control. Location: Infests thousands of acres in the Flat Tops Wilderness. Increasing in the Lookout Mountain area above Glenwood Springs. Biological Control: The defoliating moth, Calophasia lunula, has been released on Dalmatian and yellow toadflax. It may defoliate up to 20% of the leaves of the plant. Mecinus janthinus, a stem -boring weevil, is 42 Cultural Control: Education: capable of killing a large portion of the above -ground plant by boring into and killing stems where the larvae feed and live. Attempt to maintain competitive communities of desirable species. Reseed any open ground with perennial grasses to prevent invasion by other weed species. The key to management of escaped ornamentals is to create awareness among homeowners, nurseries, landscapers and landscape architects that yellow toadflax is a noxious weed and therefore should not be specified in plantings, sold in nurseries or planted in home gardens or large-scale landscape projects. Mechanical Control: Digging and pulling where feasible can provide effective control if conducted annually for 10 to 15 years. Chemical Control: Treat at flowering through fall. For specific treatments for rangeland and pasture sites, refer to the Colorado Department of Agriculture Fact Sheets — Yellow toadflax (Appendix A). 2.06 Identification of Native and Noxious Thistles A. Colorado has several species of thistle which are native and do not cause the problems of the noxious species. Some of them are very rare. An excellent reference guide is "Thistles of Colorado," published by the Larimer County Weed District. Native thistles share these characteristics: 1. They have mostly white, sometimes very pale lavender flowers and are more succulent than the noxious species. The flowers may have a hairy or fuzzy appearance and stems of some species are reddish. 2. They are valuable to pollinators and wildlife and contribute to biodiversity. 3. They are sometimes inadvertently sprayed, pulled, clipped or dug up because they are confused with noxious, non-native thistles. 4. Among the native thistles in Garfield County are Barneby's thistle (Cirsium barneybi), fringed thistle (Cirsium centaureae), Fish Lake thistle (Cirsium clavatum var. americanum), Rocky Mountain thistle (Cirsium perplexans), and adobe thistle (Cirsium perplexanis). B. Five introduced thistle species include Canada, musk, plumeless, bull and Scotch. 1. Canada thistle is a perennial and has an extensive root system. 2. Plumeless, Scotch and musk thistles are biennials. They are relatively shallow - rooted and reproduce by seed only. 43 3. Canada and plumeless are often mistaken for each other. It is very simple to tell them apart: a) Canada has a smooth stem; plumeless has a spiny stem and leaves. b) The bracts under the flower of Canada are spineless; bracts under the leaves of plumeless appear as sharp spines. c) The flowers of musk thistle are about 3 times larger than those of Canada or plumeless. 4. Musk thistle seedlings have a very prominent white midrib. 5. Scotch thistle leaves are larger than those of the other thistles. They grow up to 2 feet in length and 1 foot wide. The leaves are covered with dense hairs which give them a grey appearance. 6. The leaves of bull thistle are deeply lobed and spiny with prickly hair above and cottony hair below. Canada leaves are smooth above and smooth or hairy below. 7. All of the biennial thistles may grow to heights of greater than 6 feet. Canada thistle may grow from 1 to 4 feet tall. 44 SECTION III JURISDICTIONAL OVERVIEW OF AREAS OF INFESTATION 3.01 Overview It is the goal of Garfield County to develop and implement a comprehensive noxious weed management program on all County -owned property and to be available as a resource for private landowners and public land managers. The County has adopted an "early detection, early treatment" policy for the purpose of establishing priorities. Early detection involves identification and documentation of recently introduced weed species into an area. Early treatment is the follow-up that could possible eradicate new infestations. 3.02 County Land: Roads, Airport, Landfill A. Roads: Garfield County has over 900 miles of county roads. Roadsides shall be managed for weeds on the County's noxious weed list and Colorado listed weeds designated for eradication. 1. A Priority List of roads will be established each growing season based upon input from the Road and Bridge Department, the public and past observations by staff. Roadsides will be selectively spot -treated for noxious weeds. 2. There will be no general herbicide applications to non -listed weeds unless specifically requested by the Road and Bridge Department or the County Commissioners to treat a roadside for safety and sight reasons or to protect new paving. 3. Roadside treatment will start in the warmer, western end of the County in mid- April and move east and south as the growing season progresses. Each road on the Priority List will be treated at least twice. If time and workload allows some of the heavily infested roadsides will be treated a third time. B. Airport: The Airport will be treated on an as -needed basis for noxious weeds. 1. There are scattered infestations of Russian knapweed, musk thistle, whitetop, tamarisk and Russian olive on Airport property. 2. In 2006, ten acres of tamarisk were treated using the cut -stump method with the Rifle Correctional Crew on property along lower Mamm Creek. Annual follow-up is necessary. C. Landfill. The West Garfield County Landfill will be treated on an as -needed basis for noxious weeds. There are isolated patches of musk thistle, Scotch thistle and tamarisk at the Landfill. 3.03 State Land A. Colorado Department of Transportation's state highways in Garfield County are Highways 13, 82, 133, 139, 325 and U.S. Highway 6&24. These highways are 45 managed for noxious weeds by CDOT through their offices in Glenwood Springs, Grand Junction and Craig. 1. Goals: a. Manage all noxious weeds in accordance with the Garfield County Weed Management Plan and the latest version of State Rules and Regulations Pertaining to the Noxious Weed Act, (8CCR 1206-2). b. Establish an intergovernmental agreement with CDOT that enables the County to perform weed management on a very limited basis. The major responsibility for weed management would still lie with CDOT. 2. Key Species: a. Interstate 70: Diffuse knapweed, spotted knapweed, Russian knapweed, Scotch thistle, Russian olive, tamarisk. b. Glenwood Canyon Bike Path: Chinese clematis, Russian knapweed, hoary cress, tamarisk, common tansy, plumeless thistle, Canada thistle. c. Highway 13: Musk thistle, yellow toadflax, Russian knapweed, Scotch thistle. d. Highway 82: Plumeless thistle, Canada thistle, Russian knapweed. e. Highway 133: Oxeye daisy, yellow toadflax, plumeless thistle, Canada thistle. f. Highway 139: Whitetop, Russian knapweed, spotted knapweed, Canada thistle. g. Highway 325: Diffuse knapweed, Canada thistle, Russian knapweed. h. Highway 6&24: Diffuse knapweed, Russian knapweed, Scotch thistle, Canada thistle, whitetop. B. Colorado Division of Parks and Wildlife 1. The Colorado Division of Parks and Wildlife has a weed management program in place for the Garfield Creek State Wildlife Area. Garfield County partnered with the DPW to map the area for noxious weeds in 2009. 2. The Division has two ponds adjacent to Cottonwood Park in Parachute. Key species are tamarisk and Russian olive. 3. Rifle Gap, Rifle Falls and Harvey Gap have weed management programs for those properties. C. Garfield County is available to provide technical assistance and weed identification upon request. 3.04 Federal Land A. Bureau of Land Management The BLM within Garfield County manages its noxious weeds through the Field Offices in Silt (Colorado River Valley) and Grand Junction. Garfield County has an intergovernmental agreement with the Colorado River Valley Field Office to treat noxious weeds on BLM land as a supplement to the BLM's own program. This agreement is reviewed and modified on an annual basis. Resources are limited and may provide for approximately 10 sites per year to be treated by County crews. 46 B. White River National Forest The WRNF within Garfield County manages its noxious weeds through its Ranger Districts in Rifle, Carbondale, Eagle and through the Supervisor's Office in Glenwood Springs. The WRNF has an intergovernmental agreement with Garfield County that supplements the Forest's program. 3.05 Municipalities The towns and cities within the County include Carbondale, Glenwood Springs, New Castle, Parachute, Rifle and Silt. Municipalities have specific responsibilities as described in the Colorado Noxious Weed Act (See Section 1.03 of this plan). As of December 2015, all municipalities have a representative on the County Weed Advisory Board which serves in an advisory capacity. This cooperation does not preempt the above -stated responsibilities. Listed below are general descriptions of the weed issues in each municipality. The list is meant to provide institutional memory as to where key species are known to occur. The list is not all-inclusive. The suggested goal for each municipality is to manage all noxious weeds in accordance with the latest version of State Rules and Regulations Pertaining to the Noxious Weed Act (8CCR 1206-2). A.

Garfield County worked with other Western Slope counties to develop a weed management plan for UP in 2010. Portions of the rail line between Glenwood Springs and Rifle were mapped by the County in 2009 with the cooperation of UP. A. Suggested Goal: Manage all noxious weeds in accordance with the Garfield County Weed Management Plan and the latest version of State Rules and Regulations Pertaining to the Noxious Weed Act (8CCR-1206-2). B. Key Species: Scotch thistle, tamarisk, Russian knapweed, whitetop, Russian olive, common tansy, Chinese clematis. 49 SECTION IV IMPLEMENTATION OF WEED MANAGEMENT PLAN 4.01 Objectives and Goals A. Management Goals for Weed Species. Management goals will vary from species to species, by location and over time. 1. For some species, such as Colorado List A species, complete eradication of existing infestations and total suppression of newly identified infestations is mandated by State law. 2. Containment of existing intentional plantings, exclusion of seed from new wildland or open space mixes and elimination of targeted escaped infestations are goals for certain ornamentals such as oxeye daisy. 3. Russian knapweed, tamarisk and Russian olive infestation are so widespread that they must be managed, in many cases, merely for containment and reduction in the rate of spread. Eradication of these stands may only be viewed as unlikely in some instances or as a long range objective. B. Objectives: 1. Develop and implement a comprehensive noxious weed management program on all County -owned property. 2. Educate the public concerning weed management issues. 3. Foster a spirit of cooperation among federal, state and local government agencies and private landowners. 4. Work with other government agencies and departments to institute Best Management Practices and policies that stress prevention as a weed management tool. 5. Promote and use integrated management techniques. 6. Establish and maintain healthy plant communities with native or beneficial vegetation. 7. Restore and maintain desirable plant communities, healthy ecosystems and productive agricultural lands in Garfield County. 8. Stop the spread of noxious weeds to non -infested lands. 9. Contain heavily weed -infested areas. 10. Implement Title 35, Article 5.5, of the Colorado Weed Management Act (8CCR 1206-2). C. In all cases, revegetation either from the existing seed bank or through supplemental planting must be included as a management goal. Without revegetation, disturbed or denuded soils invite weed infestation. 50 4.02 Prevention and Detection Prevention is the highest priority weed management technique on non-infested lands. Among government officials, land managers, farmers, ranchers and the general public there is a growing recognition that protecting weed-free plant communities is the most economical and efficient land management practice. A. Weed-free plant communities: 1. Provide essential wildlife habitat and forage. 2. Save ranchers and farmers many billions of dollars in labor costs and lost production. 3. Ensure aesthetic and recreational qualities of an area. 4. Prevent soil erosion and improve water quality. The spread of noxious weeds is most likely to occur where soil has been disturbed either by human activities such as road and trail cuts, construction sites, the spread of gravel, road fill and topsoil contaminated with noxious weed seed, or over-grazing. B. Exotic plants and seeds such as oxeye daisy, purple loosestrife, chicory, toadflax and Russian olive escape from our yards and gardens. Since they are attractive and establish themselves quickly, they are popular with landscapers and gardeners for ornamental planting and may be purchased through nurseries. They have the same ability to dominate and spread, however, as other better known noxious weeds. C. Other methods of weed introduction include: 1 Contaminated seed, feed grain, hay, straw and mulch. 2. Movement of contaminated equipment, cars, bikes, etc. across uncontaminated lands. 3. Animal fur, fleece, human clothing. 4. Dried flower arrangements. D. Prevention is best accomplished by ensuring that new weed species seed or vegetative reproductive plant parts are not introduced into new areas, and by early detection of any new weed species before they become widespread. E. Strategies to prevent the introduction or establishment of noxious weeds in areas not already infested include: 1. Identification and eradication of small, new infestations. 2. Continuous monitoring and evaluation to prevent recurrence. 3. Identification of existing conditions, disturbances and activities that represent a potential threat to native habitat. 4. Identification of recently introduced weed species that represent a future threat. 5. Timely revegetation and reclamation of disturbed sites using appropriate native plant species. 6. The use of weed-free seeds and mulch. 7. County-wide promotion of the Colorado Weed Free Hay and Forage program. 8. Prioritization of weed management along areas of entry and dispersal. 51 9. Discouraging the sale of weedy ornamental plants and seed packets that contain weeds. 4.03 Garfield County Gravel Purchase Guidelines A. The County shall require the following before agreeing to purchase any gravel for County projects: 1. The gravel pit shall be inventoried and mapped by the pit operator for all plant species on Garfield County's noxious weed list on an annual basis. 2. The gravel pit operator shall provide the County with a weed management plan. Noxious weeds shall be treated prior to seed formation. 3. The gravel pit operator must supply the County with a detailed treatment record. 4. The County will inspect the pit, the inventory and the application records 2 weeks prior to the purchase of gravel or other aggregates. 4.04 Education and Awareness A. Education must play a major role in implementing the weed management plan. Groups targeted for public education include farmers and ranchers, golf course managers, homeowner associations, private citizens, housing developers, gardeners, landscapers, nurseries, public and private land management agencies, recreational users, youth groups, schools, oil and gas companies, pipeline companies and other utilities. B. A partnership of the public and private sectors, along with awareness of noxious weeds and the problems they cause, is essential to maintain or create plant communities that are free of noxious weeds. C. Knowledge about how to identify weeds, how and where weeds are spread and what it takes to manage weeds is needed. D. Continuation and expansion of current educational programs as well as the development of new programs is a priority of the Garfield County Noxious Weed Management Plan. E. Garfield County Vegetation Management and other governmental agencies will provide this instruction. Workshops will be held throughout the year to enhance public awareness. F. Opportunities for education include: 1. Updates on County Website. 2. Widespread distribution of informative printed material. 3. Offering weed tours and talks to the public. 4. Private applicator certification, applicator safety and laws and regulations. 5. Proper calibration of spraying equipment. 6. Contacting area nurseries, landscapers and landscape architects to emphasize the problems created by escaped ornamentals. 52 7. Cooperation with local media to disseminate weed information. 8. Custom weed management recommendations for individual landowners. 4.05 Land Stewardship The Colorado Noxious Weed Act requires that all property owners use integrated methods to manage noxious weeds. Weed management must be ongoing, requiring an integrated approach in which proper land stewardship practices are utilized. Most weed species, if detected early, can be managed. A. Strategies for implementing a noxious weed management plan: 1. Identify your plants. 2. Understand the target weed. Does it reproduce by seed or roots or both? 3. Maintain inventory maps. 4. Develop a noxious weed database. 5. Develop site-specific weed management plans in cooperation with other individual landowners and public agencies. 6. Develop a decision-making process that uses site-specific information to make decisions about treatment choices. 7. Develop a long-term strategy including regular monitoring of treatment areas. 8. Correct the situation or practices that allowed the weeds to spread. 9. Take necessary action. B. Maintaining land that is free of weeds is good stewardship. Landowners who do not manage their weeds place their neighbors' land at risk. 4.06 Revegetation A crucial part of any weed management plan is the reintroduction of site -appropriate vegetation. A. Establishing a desirable plant community after noxious weeds have been removed from a highly infested area requires timely cultivation and reseeding. B. Since the seeds from noxious weeds may lay dormant for many years, removing all visible signs of the noxious weeds does not ensure against their return. C. Revegetation can help prevent the germination of weed seeds. It is important to inspect the land regularly to identify and treat small, new infestations. D. For proper revegetation, managed irrigation of dry areas and reseeding are essential to establish desirable communities. E. Native plants are most appropriate when the goal is restoration of native habitat. F. Weed -free seeds of native Colorado grasses, wildflowers or plant species appropriate to the site may be purchased, but the best source for seeds is from native species that grow in the immediate vicinity of the infestation. They will be best adapted to local conditions and will help maintain local integrity and genetic viability. 53 G. Using native plants or seeds to revegetate disturbed land reduces degradation of native ecosystems, reduces the need for herbicides and conserves water resources. H. Native plants provide broad biological diversity and help keep the Colorado landscape from being irrevocably altered by non-native species. I. When the goal is reclamation — reseeding for quick ground cover establishment or erosion control — it may be appropriate to use introduced, non-aggressive grasses and forbs. J. Contact the Natural Resources Conservation Service or Colorado State University Extension for specific seeding recommendations. General seeding recommendations: a) Study all vegetation in the area and surrounding areas. b) Preserve plant species native to Colorado. c) Test the soil for pH balance. d) Retain and utilize as much on-site topsoil as possible. e) Select a predominant species that is appropriate to the site. Then choose a few complementary species to provide a balanced plant community. f) Choose plants that are healthy, vigorous and pest -free. g) Use weed -free, non -hybrid seeds. h) Avoid commercial seed packets containing exotic plant species. i) Confirm viability and purity of seed through seed testing from an accredited seed testing lab. j) When choosing seeding rates, consider the guidelines provided by the Natural Resource Conservation Service. Fact sheets are available for individual species at the USDA-NRCS Plants Database website: http://plants.usda.gov/java/factSheet. 4.07 Requirements — Reclamation/Revegetation Plan, Soil Management Plan and Security Various land use change permits processed through the Community Development Departments (e.g. grading, pipeline, and Land Use Change permits) may require a Reclamation/Revegetation and Soil Management Plan which includes a Weed Management Plan. A. Soil Plan to include: 1. Provisions for salvaging on-site topsoil. 2. Timetable for eliminating topsoil and aggregate piles. 3. Provision for soil cover if any disturbances or stockpiles that sit exposed for a period of 90 days or more. B. Reclamation/Revegetation Plan to include: 1. Plant material list and seed mix. Specifically, scientific names and common names and the application rate in terms of Pure Live Seed per acre. 54 2. Planting schedule which includes timing, methods, mulching and provisions for watering, if applicable. 3. A map of the impacted area with a calculation of the surface area of disturbance in acres of the disturbed area, at preliminary plan. 4. A Weed Management Plan for all listed Garfield County noxious weeds and State of Colorado listed noxious weeds that are targeted for statewide eradication. The Plan will include a site specific map and weed inventory. A Weed Management Plan is required if an area 1 acre or greater is disturbed for the purposes of site construction, development or grading but not including areas serving the long- term function of the site such as building footprint, road surface or permanent parking areas. 5. A revegetation security in cash, bond or letter of credit. 6. Agricultural practices are exempt from revegetation requirements unless they are in association with a subdivision or land use proposal. C. A financial security may be required for revegetation if, in the determination of the BOCC, the proposed project has: 1. A potential to facilitate the spread of noxious weeds. 2. A potential to impact watershed areas. 3. A potential for visual impacts from public viewing corridors. 4. Steep slopes of 15% or greater or unstable areas. 5. Disturbs large areas of 1 acre or greater where topsoil is exposed for the purposes of site construction, development or grading but does not comprise the long term functioning of the site (i.e. building footprint, road surface or permanent parking areas). D. The revegetation security will be in an amount to be recommended by the Vegetation Manager to the BOCC that will be site-specific and based on the amount of disturbance. 1. The security shall be held by Garfield County until vegetation has been successfully reestablished, or for a period of time approved by the BOCC, in any specific land use action, according to the Reclamation Standards. 2. The BOCC will designate a member of its staff to evaluate the reclamation prior to the release of the security. E. If a property owner fails to comply with his/her approved Reclamation/Revegetation and Soil Management Plan, the provisions of the County's adopted land use and development code in regard to enforcement may be in effect. 4.08 Reclamation Standards Areas disturbed during development shall be restored as natural -appearing landforms that blend in with adjacent undisturbed topography within 90 days of completion of construction unless an alternative timeframe is approved by the Vegetation Manager. A. Site Stability. The reclaimed areas shall be stable and exhibit none of the following: 55 1. Large rills or gullies. 2. Perceptible soil movement or head -cutting in drainages. 3. Slope instability on or adjacent to the reclaimed area. 4. Slopes shall be stabilized using appropriate reshaping and earthwork measures, including proper placement of soils and other materials. B. Soil management. Topsoil management shall be salvaged from areas to be disturbed and managed for later use in reclamation. C. Erosion Prevention. The surface area disturbed at any one time during the development of a project shall be kept to the minimum necessary and the disturbed areas reclaimed within 90 days to prevent unnecessary or undue degradation resulting from erosion. 1. The soil surface must be stable and have adequate surface roughness to reduce run-off, capture rainfall and snow melt, and allow for revegetation. 2. Application of certified noxious weed -free mulch or erosion netting may be necessary to reduce soil movement, retain soil moisture and promote revegetation. 3. Soil conservation measures, including surface manipulation, reduction in slope angle, revegetation and water management techniques shall be used. 4. Sediment retention structures or devices shall be located as close to the source of the sediment -generating activities as possible to increase their effectiveness and reduce environmental impacts. D. Contouring and Revegetation. Abrupt transitions and linear placement on visible slopes shall be avoided. Areas disturbed by grading shall be contoured so they can be revegetated and shall be planted and have vegetation established. 1. When final landform is achieved, the surface shall be stabilized by vegetation or other means to reduce further soil erosion from wind or water, provide forage and cover, prevent fugitive dust as required by State Statute, and reduce visual impacts. 2. A uniform vegetative cover shall be established with an individual plant density of at least 70% of pre -disturbance levels within 4 growing seasons. State or county -listed noxious weeds, as well as alien annual invasive species, do not count as part of the 70% cover. 3. Application of topsoil. Topsoil will be stockpiled, placed on disturbed areas and managed for later use in reclamation. Provisions for salvaging on-site topsoil, a timetable for eliminating topsoil and aggregate piles and a plan that provides for soil cover if any disturbances or stockpiles sit exposed for a period of 90 days or more will be reviewed and accepted by the Garfield County Vegetation Manager. 4. Specific criteria for evaluating revegetation success must be site-specific and included as a part of the reclamation plan. 5. Vegetation production, species diversity and cover shall support the post - disturbance land use. 56 6. Areas where post -disturbance land use does not include lawns, gardens and flower beds shall approximate the surrounding undisturbed areas or be revegetated to a desired plant community with a composition of species and plant cover typical to that site. 7. The vegetation shall stabilize the site and support the planned post -disturbance land use, provide natural plant community succession and development, and be capable of renewing itself. This shall be demonstrated by: a. Using certified noxious weed -free seed. b. Successful on-site establishment of the species included in the planting mixture or other desirable species. c. Evidence of vegetation reproduction, either spreading by rhizomatous species or seed reproduction. d. Evidence of overall site stability and sustainability. 8. The revegetation plan shall provide for the greatest probability of success in plant establishment and vegetation development by considering environmental factors such as seasonal patterns of precipitation, temperature and wind, soil texture and fertility, slope stability and direction of slope faces. 9. To ensure the establishment of a diverse and long-lasting vegetative cover, the permittee shall employ appropriate techniques of site preparation and protection. 10. Species diversity should be selected for long-term land uses and provide for a reduction in visual contrast. 11. Where vegetation is to be used, a diversity of vegetation species shall be used to establish a resilient, self-perpetuating ecosystem capable of supporting the post - disturbance land use. 12. Species planted should include those that will provide quick soil stabilization, litter and nutrients for soil building and are self -renewing. 13. Integrated weed management methods shall be employed for all noxious weed species on the Garfield County List. Weed management methods shall be used whenever the infestation of the reclaimed area by noxious weeds threaten nearby areas. 14. Where revegetation is impractical or inconsistent with the surrounding undisturbed areas, other forms of surface stabilization shall be used. 4.09 Mapping and Inventory A. The Vegetation Manager will establish and maintain visual maps of past and present infestations of noxious weeds on County land. This will provide a graphic representation of weed management progress and needs. B. The primary goal of mapping will be to record the noxious weed species present, areas infested, density of infestations and other site factors pertinent to successfully managing the infestation. 57 C. Mapping priorities will be List A species, List B species designated for eradication and support for future grant -funded projects. 58 SECTION V ENFORCEMENT The control of noxious weeds is the responsibility of the subject property's owner or occupant. The Garfield County Vegetation Manager is available to provide technical assistance. Enforcement of the Garfield County Weed Management Plan is authorized by the Colorado Noxious Weed Act (the Act), C.R.S 35-5.5-101.1, et seq. The Act directs local governments to take the necessary steps to manage noxious weeds in their jurisdiction, and provides specific authorization for local enforcement of duly adopted Weed Management plans. Garfield County will manage noxious weeds identified in the Garfield County Weed Management Plan and the Act in accordance with the following procedures: 5.01 Compliance: Private Lands A. Inspection: Garfield County, through its delegates, agents and employees shall have the right to enter upon any premises, lands or places whether public or private, during reasonable business hours for the purpose of inspecting for the existence of noxious weed infestations when at least one of the following has occurred: 1. The landowner had requested an inspection. 2. A neighboring landowner or occupant has reported a suspected noxious weed infestation and requested an inspection. 3. An authorized agent of the County has made a visual observation from a public right-of-way or area and has reason to believe that a noxious weed infestation exists. B. No entry upon any premises, lands or places shall be permitted until the landowner or occupant has been notified by certified mail that such an inspection is pending. Where possible, inspections shall be scheduled and conducted with the concurrence of the landowner or occupant. 1. If after receiving notice that an inspection is pending, the landowner or occupant denies access to the Garfield County inspector, the inspector may seek an inspection warrant issued by a municipal, county or district court having jurisdiction over the land. The court shall issue an inspection warrant upon presentation by Garfield County, through its agent or employee, of an affidavit stating: a. The information which gives the inspector reasonable cause to believe that any provision of the Act or the Garfield County Weed Management Plan is being or has been violated. b. That the occupant or landowner has denied access to the inspector. c. A general description of the location of the affected land. 2. No landowner or occupant shall deny access to such land when presented with an inspection warrant. 59 C. Management 1.

The arbitration panel will be required to develop the final management plan not more than 2 calendar weeks after the hearing is completed. g. In the event of non-compliance with any management plan developed and approved by the arbitration panel, in addition to remedies set forth in paragraph 5.01(D), the arbitration panel shall have the ability to award costs of the arbitration to the prevailing party including the arbitration panel fees and expenses. h. These fees and expenses may include, but are not limited to salary, wages, travel and per diem expenses. D. Failure to Comply. In the event the landowner or occupant fails to comply with the notice to manage the identified noxious weeds or fails to implement the plan developed by the arbitration panel, the Garfield County Board of County Commissioners has the authority to: 1 Compel management of the noxious weeds after notice to the landowner and a hearing. The Garfield County Vegetation Department or its representative shall give written notice of the hearing before the Garfield County Board of County Commissioners to the landowner personally or by certified mail which will include: a. Description of the affected land. b. Name of the noxious weeds and their location on the land. c. Date and time the Garfield County Vegetation Management Department or its representative will perform weed control on the land. d. Method of control to be applied. e. A statement that the Garfield County Board of County Commissioners may assess the whole cost of compliance, including up to 20% for inspection and other incidental costs in connection therewith, upon the lot or tract of land where the noxious weeds are located. Such assessment shall be a lien against the subject lot or tract of land until paid and shall have priority over all other liens except general taxes and prior special assessments. Such assessment may be certified to the Garfield County Treasurer and collected or paid over in the same manner as provided for the collection of taxes. Any funds collected pursuant to this section shall be deposited in the Garfield County Weed Fund or any similar fund. 61 2. Costs of providing for and compelling weed management shall not be assessed until the level of management called for in the notice or as developed by the arbitration panel has been successfully achieved. 3. Public Nuisance. If the landowner fails to comply with the notice to control the designated noxious weeds, fails to submit an acceptable management plan, or fails to comply with a management plan as determined by an arbitration panel, the Garfield County Board of County Commissioners may declare the noxious weeds a public nuisance pursuant to C.R.S. 35-5.5-113. Once declared, such nuisances are subject to all laws and remedies relating to the prevention and abatement of nuisances. E. Other occupants. Whenever the land is known to the Garfield County Vegetation Management Department or its representative to be occupied by someone other than the record owner, written notices also shall be given to the occupant, and the occupant shall be informed that pursuant to C.R.S. 35-5.5-109 and the Garfield County Weed Management Plan imposes on occupants the same responsibilities for noxious weed control as it imposes on landowners. F. Notice. 1. Whenever notice is given by mail, it shall be deemed given when deposited in a regular depository of the United States Postal Service, postage prepaid. 2. Notice to landowners shall be mailed to the affected lot or tract's physical address and the landowner's last known address as shown in the County Assessor's records, and any other addresses the occupant has provided to the Garfield County Vegetation Management Department. 3. Notice to occupants shall be mailed to the affected lot or tract's physical address and any other addresses the occupant has providedto the Garfield County Vegetation Management Department. G. Condition Precedent. No private land management shall be compelled without first applying the same or greater management measures to the County land or rights-of- way that are adjacent to the private property. 5.02 Compliance: Public Lands A. Municipalities. The governing body of each municipality in Garfield County shall adopt a noxious weed management plan pursuant to C.R.S. 35-5.5-106 for all lands within its jurisdiction. 1. Municipalities adopt and provide for the enforcement of such ordinances, resolutions, rules and other regulations as necessary to enforce such a plan. 2. Any municipal agent, delegate, employee, staff or contractor applying or recommending the use of chemical management methods in the administration of the Weed Management Plan shall be certified by the Colorado Department of Agriculture. 62 3. Municipalities may cooperate with counties and other municipalities to exercise any and all powers and authorities granted by the Act by entering into intergovernmental agreements. B. State Land. State boards, departments or agencies that administer or supervise state lands must manage noxious weeds pursuant to C.R.S. 35-5.5-110 on any lands under its jurisdiction, using methods prescribed by the local governing body in whose jurisdiction the state lands are located. 1. The Garfield County Board of County Commissioners, through its employees and agents, may give notice to the state board, department or agency advising of the presence of noxious weeds on public lands. This notice will specify the best available methods of integrated management. Wherever possible Garfield County shall consult with the state entity in development of a plan for the management of noxious weeds on the premises or lands in question. 2. Within a reasonable time after the receipt of the notification, not to exceed 10 days, the state entity shall do one of the following: a. Option I: Comply with the terms of the notification; b. Option II: Submit an acceptable management plan and a schedule for its completion to the Garfield County Vegetation Management Department; c. Option III: Request an arbitration panel to determine a final management plan. 3. If the state entity chooses Option I, the Garfield County Vegetation Management Department or its representative will re-inspect the land to confirm compliance within a reasonable period of time not to exceed 10 days, or 5 days for State List A species and populations of State List B species designated for eradication. 4. If the state entity chooses Option II, the Garfield County Vegetation Management Department or its representative will review the proposed weed management plan and determine its efficacy. a. If the plan is acceptable, the Department will monitor the state's compliance with the management plan, and after completion, will re-inspect to ensure the noxious weeds have been effectively managed. 5. If the state entity chooses Option III, an arbitration panel will be selected by the Garfield County Board of County Commissioners in accordance with C.R.S. 35-5.5-110(2)(b). The arbitration panel shall be comprised of a weed management specialist or weed scientist, a landowner of similar land in Garfield County, and a third panel member chosen by agreement of the first two panel members. 6.

The Garfield County Vegetation Management Department or its representative shall give written notice, personally or by mail, of the hearing date and time to any state entity. The state entity is entitled to appear before the panel, individually or by representative. 10. The arbitration panel will be required to develop the final management plan not more than 2 calendar weeks after the hearing is completed. C. Failure to Comply. In the event the state entity fails to comply with the notice to manage the identified noxious weeds, or implement the plan developed by an arbitration panel, the Garfield County Vegetation Management Department may undertake management of the noxious weeds at the expense of the state entity. 1. A written agreement for payment of the costs of noxious weed management will be reached within 2 weeks after the date such expenses are submitted to the state entity. 2. If no agreement for payment is reached, and if the costs of the noxious weed management is not immediately paid, such charge will be submitted to the controller who shall treat such amount as an encumbrance to the budget of the state entity, pursuant to C.R.S. 35-5.5-112. 3. Any state entity may enter into a contract with Garfield County to authorize management of noxious weeds on state -administered property on terms and conditions satisfactory to both parties. D. Federal land. Local governing bodies of all counties and municipalities are authorized pursuant to C.R.S. 35-5.5-111 to enter into cooperative agreements with federal and state agencies for the integrated management of noxious weeds within their jurisdictions. 1. Bureau of Land Management. The BLM within Garfield County manages its noxious weeds through its Field Offices in Silt (Colorado River Valley) and Grand Junction. Garfield County has an intergovernmental agreement with the Colorado River Valley Field Office to treat noxious weeds on BLM land as a supplement to the BLM's own program. This agreement is reviewed and modified on an annual basis. Resources are limited and may provide for approximately 10 sites per year to be treated by County crews. 2. The White River National Forest has an intergovernmental agreement with the County to supplement the Forest program. Within Garfield County the Forest manages its noxious weeds through its Ranger Districts in Rifle, Carbondale and through the Supervisor's Office in Glenwood Springs. 64 5.03 County Rights -of -Way Garfield County and each state entity must confirm that all public roads, highways, rights-of-way, and any easements pertaining to these, under the jurisdiction of these entities, are in compliance with C.R.S. 35-5.5-112, and any violations of the Act shall be the financial responsibility of the Garfield County or state entity. 65 SECTION VI PLAN EVALUATION 6.01 Plan Evaluation A. The goals and plan of work in the Garfield County Noxious Weed Management Plan will be reviewed and evaluated annually at the February Garfield County Weed Advisory Board meeting. Any proposed additions or changes shall be recommended by the Board and approved by ordinance by the BOCC before becoming final. B. The Garfield County Weed Management Plan shall be reviewed by the Weed Advisory Board at least every 3 years (C.R.S. 35-5.5-107(4)(a)). The management plan and any recommended amendments to the plan shall be transmitted to the BOCC for approval, modification or rejection. 66 APPENDIX A N-171 0 O 0 Updated on: 08/08 List B Species Colorado Dept. of Agriculture, Conservation Services Division 700 Kipling Street Suite 4000 Lakewood, CO 80215 303-239-4100 Key ID Points 1.

Rangeland, pasture, and riparian site recommendations Absinth wormwood Identification and Management Identification and Impacts Absinth wormwood (Artemisia absinthium) is native to Eurasia, the Middle East and North Africa. It was introduced to North America in the early 19th century to be cultivated for medicinal use. It was first reported outside cultivated gardens in 1841, along roadsides and waste grounds. bsinth wormwood is a long- lived perennial that possesses a strong sage odor and bitter taste. Plants grow 2 to 4 feet in height and are prolific seed producers. It has a taproot that can reach 2 inches in diameter and shallow lateral fibrous root branches that can extend up to 6 feet long in all given directions. Plants are woody at the base and regrow from the soil level each spring. The stems are numerous and are covered with fine, gray hairs while the leaves area blue -olive green, alternate and highly divided. Flowers are small, yellowish and arranged in large, spike-like panicles. The seed viability is estimated to be 3 to 4 years and are easily scattered by wind, water, animals, and in hay. The seeds are less than 1/6 inch long, smooth, flattened and light gray. Habitats for Absinth wormwood include disturbed sites, moist soils, and is also shade tolerant. It can occur in 5,000 to 7,000 feet elevation and is considered a weed in pastureland, cropland, and rangeland. Absinth wormwood is listed as poor palatability in horses, but good for sheep. The key to effective control of Absinth wormwood is a combination of control methods. Compared to most perennials, it is fairly easy to control with chemicals in combination with mechanical control. Details on the back of this sheet can help to create a management plan compatible with your site ecology. Absinth wormwood is designated as a "List B" species in the Colorado Noxious Weed Act. It is required to be either eradicated, contained, or suppressed depending on the local infestations.

Shallow lobed leaves that have sticky hairs. 2. Flowers have purple centers and veins. Rangeland, pasture, and riparian site recommendations Black henbane Identification and Management Identification Impacts and Black henbane (Hyoscyamus niger) was introduced from Europe as an ornamental and medicinal herb. In Colorado it is mostly found on the western slope. The plant blooms June through September and may be an annual or biennial. A mature plant reaches 1 to 3 feet in height with foliage that has a fowl odor. Leaves are shallowly lobed to coarsely toothed with sticky hairs. The outer part of the flower is brownish yellow in color with a purple center and veins. Fruits are approximately 1 inch long with 5 lobes. All parts of Black henbane are poisonous to both livestock and humans when ingested. However; the plant is usually avoided by livestock due to the foul odor. The plant is a strong competitor for moisture and nutrients and produces a persistent litter effecting germination and growth of native plants. Black henbane invades disturbed and overgrazed sites. A good preventable measure is to guard against overuse. Habitats for Black henbane included disturbed open spaces, roadsides, fields, waste places and abandoned gardens. It grows in most soil types but likes sandy or well drained loam soils. The seed viability or longevity is considered to be 1 to 5 years. The key to effective control of Black henbane is guarding against disturbance and overuse, this can prove to be a good preventative measure against black henbane. Mechanical control and chemicals are the most commonly recommended method. Controlling plants in the spring or early summer prior to seed production is most effective, follow-up treatments are recommended to pick up missed or late bolting plants. Details on the back of this sheet can help to create a management plan compatible with your site ecology. Black henbane is designated as a "List B" species in the Colorado Noxious Weed Act. It is required to be either eradicated, contained, or suppressed depending on the local infestations.

Bouncingbet is increasingly common in Colorado, particularly in residential areas and local open spaces where it has escaped as an ornamental species. Bouncingbet was originally introduced from Europe as a garden ornamental. • Updated on: 08/08 Key ID Points 1. Leaves are opposite, smooth, narrow, and 2-4 inches long. 2. Flowers have five petals and are generally light pink to white. Identification and Impacts Bouncingbet (Saponaria officinalis) is a perennial forb. The flowers are crowded at the ends of branches, and have five petals that are generally light pink to white and slightly notched at the apex. Flowering begins in July and continues until September. The fruits are many -seeded capsules and seeds are dull -black and roundish or kidney -shaped. Bouncingbet reproduces by seed and spreads by rhizomatous swollen nodes. Leaves are opposite, smooth, narrow, 2 to 4 inches long and have three distinct veins from the base. The stems are erect, sparingly branched, smooth, and forming. Mature plants grow up to three feet tall. Bouncingbet can be poisonous to livestock and humans. It is generally considered unpalatable to livestock. The plant contains sapogenic glycosides that cause gastrointestinal irritation and can destroy red blood cells when absorbed in the blood streams of grazing animals. The habitat of Bouncingbet is often found in large dense patches on hillsides, along rivers, roadsides, meadows, and waste areas. It prefers moist, well -drained soil, and full sun to partial shade and is currently found primarily in municipal areas and nearby wildlands. Bouncingbet spreads rapidly, replacing The key to effective control of Bouncingbet is early detection and prevention of new infestations, since it is not yet widespread in Colorado. If infestations are discovered, they should be controlled immediately, and all seed production prevented. Since Bouncingbet usually grows in dense patches it is relatively easy to spot and treat. Be aware that this species is often found in wet areas, which may restrict the use of certain herbicides. As with all perennial weeds that have extensive root systems, the key to controlling Bouncingbet, is to eliminate seed production while depleting the nutrient reserves in the roots. Details on the back of this sheet can help to create a management plan compatible with your site ecology. Bouncingbet is designated as a "List B" species in the Colorado Noxious Weed Act. It is required to be either eradicated, contained, or suppressed depending on the local infestations.

Rangeland, pasture, and riparian site recommendations 1 Bull thistle Identification and Management Heavy infestations can reduce livestock forage. Additionally, the presence of bull thistle in hay decreases the forage value and lowers the market price. It is an aggressive weed, but it will not withstand cultivation. Bull thistle is often a transient species, appearing in recent clear cuts or disturbed areas and becoming a dominant species for several years. It has been reported to cause hay fever in some individuals and is often confused with musk thistle. Identification and Impacts Bull thistle (Cirsium vulgare (Saw) Tenore) is a biennial forb that was introduced to North America as a seed contaminant and is now widespread. Gumdrop - shaped flowers are pinkish to dark purple in color and 1 1/2 to 2 inches in diameter. The flower bracts are somewhat tapered and covered with spines. Seeds are capped with a circle of plume -like white hairs. Leaves are alternate. In Colorado, Bull thistles are the only species that are prickly hairy on the top and are cottony -hairy on the undersides of the leaves. In mature plants the leaves extend down, clasping the stem and are divided into segments. The plant has a short, fleshy taproot with several primary roots extending from the root crown. Seed leaves are round to spatulate, and smooth. Mature plants can produce up to 4,000 seeds per plant. Habitats for Bull thistle include dry to moist environments. It thrives on nitrogen -rich soils, and it grows on gravelly to clay -textured soils. Bull thistle cannot withstand deep shade and is commonly seen in areas such as pastures, overgrazed rangeland, roadsides, and logged areas. Within Colorado Bull thistle infestations have been reported to occur in nearly all counties west of the continental divide, this plant has also been observed in the Upper Arkansas Watershed and in pockets on the plains. It is widespread throughout the United States and parts of Canada. The key to effective control of Bull thistle is maintaining healthy pastures and rangeland, guarding against disturbance or overuse, and as with most biennial limit seed production. To reduce seed production, plants with buds or flowers should be collected and immediately disposed of or destroyed. Chemical control is most effective when plants are in rosette stage, spring or early fall. Mechanical controls can be used to eliminate small patches or plants in a later growth stages. Details on the back of this sheet can help to create a management plan compatible with your site ecology. Bull thistle is designated as a"List B" species in the Colorado Noxious Weed Act.

Rangeland, pasture, and riparian site recommendations Canada thistle Identification and Management Canada thistle is one of the most feared noxious weeds in the U.S. as it can infest many land types, from roadsides, ditch banks, riparian zones, pastures, irrigated cropland, to the most productive dryland cropland. Forage production is severely reduced because cattle will not graze near infestations. Canada thistle during the flowering stage. This stage typically occurs in the early summer. Seed production will follow and effective management options will then become limited. Identification and Impacts Canada thistle (Cirsium arvense) is a non-native deep-rooted perennial that spreads by seeds and aggressive, creeping, horizontal roots (rhizomes). Canada thistle can grow 2 to 4 feet in height. The leaves are oblong, spiny, bright green in color, and are only slightly hairy on the undersurface. Flowers occur in small clusters that form on the ends of branches. They are about 1 cm in diameter, tubular shaped, and vary from white to purple in color with a strong vanilla scent (female flowers). Canada thistle emerges from its root system from late April through May. It begins to flower in late spring to early summer with increase in day length. Canada thistle only produces about 1,000 to 1,500 seeds per plant. Typically, it reproduces vegetatively through a creeping root system, and can quickly form dense stands. Every piece of root, from 1/2 to 1 inch in length, is capable of forming new plants. The key to controlling Canada thistle is to eliminate seed production and also to reduce the plant's nutrient reserves in its root system through persistent, long-term management. The key to effective control of Canada thistle is combining control methods. These weeds need to be continually stressed, forcing it to exhaust root nutrient stores and eventually die. Of all control methods, prevention is most important. Maintain healthy pastures and rangeland and continually monitor your property for new infestations. Details on the back of this sheet can help to create a management plan compatible with your site ecology. Canada thistle is designated as a"List B" species on the Colorado Noxious Weed Act.

The first year of growth is a basal rosette, producing large cordate, thickly hairy leaves. The second year of growth, is a coarse, multi -branched, erect stem that will grow to heights of 3 to 10 feet tall. The large, dark green leaves are alternate and appear to have toothed or wavy margins. They are broadest and the base of the leafand diminish as they approach the tip of the leaf, and have a hairy underside. The flowers appear at the end of the branches, numerous, clustered and are pink to purple in color. At the base of the flower there are many spines that often have a hook on the end. The flower and the spines dry and becomesaneasilydispersiblebur. Flowering and seed production occur from July to October. The plant grows from a sturdy taproot that is brown and fleshy in color. Habitats for Common burdock include roadsides,ditch banks, wasteplaces,pastures,andfencerows. Animals will avoid eating the plant in both years of growth, the first year duetothehairyleavesandthesecond year due to the spines and burs.

Rangeland, pasture, and riparian site recommendations 1 Common tansy Identification and Management Identification and Impacts Common tansy (Tanacetum vulgare L.) is a perennial plant that reproduces by both seed and creeping rootstocks. Seeds are yellowish brown achenes with short, five -toothed crowns. Yellow flowers are numerous in flat-topped dense clusters at the tops of the plants. Button -like flower heads lack ray flowers. Flowering typically occurs from July to September. The leaves are alternate, deeply divided into numerous narrow, individual leaflets. Mature plants are 1.5 to 6 feet tall. Stems are often purplish -red in color and extensively branched towards the top. The foliage emits a strong odor when crushed. Habitats for Common tansy include along roadsides, streams, irrigation ditch banks, waste places, ornamental beds and in pastures. It grows best in full sun and on fertile, well -drained soil. Common tansy is found throughout the United States, although it is native to Europe. Common tansy is considered undesirable forage for livestock. The plant is considered toxic if large quantities are consumed; fortunately animals rarely ingest it as it is very unpalatable. Common tansy can impact forage quality and quantity. With adequate moisture common tansy will displace native and other desirable species. The key to effective control of Common tansy is to stop the establishment and spread of infestations. Mechanical and hand cutting/pulling can assist with limiting seed production, but will not eradicate plants. Common tansy is considered toxic, use protective equipment when controlling. Another effective contol method is using herbicides. A combination of these two methods, will offer desirable results. Since Common tansy grows rhizometously, depleting the storage of carbohydrates in the root system will help control the plants. Details on the back of this sheet can help to create a management plan compatible with your site ecology. Common tansy is designated as a"List B" species in the Colorado Noxious Weed Act. It is required to be either eradicated, contained, or suppressed depending on the local infestations.

Rangeland, pasture, and riparian site recommendations Common teasel Identification and Management fairly easily, due to the bare ground where the basal leaves were. Common teasel is native to Europe where it historically had many uses. Identification and Impacts Common teasel (Drpsacus spp.) is a biennial or sometimes monocarpic perennial forb. The fruits are a four -angled achene, each containing a single seed. Common teasel can produce more than 2,000 seeds per plant. The flowers are purple or white with spiny, awned bracts at the base. The flower head is generally egg-shaped, with a square base. The floral bracts at the base of the head are generally longer than the head. Rosette leaves are conspicuously veined, with stiff prickles on the lower midrib and appear to be wrinkled. Stem leaves are simple, opposite, net - veined, stalkless, and clasp the stem. Mature plants can grow up to or over six feet tall. The taprooted stem is rigid with several rows of downward turned prickles. Plants die after production of seed has occurred. Habitats for Common teasel include open, sunny habitats that range from wet to dry levels. It is generally found along irrigation ditches, rivers, abandoned fields, pastures, waste places, and forests. Common teasel is spreading rapidly in America, particularly in the Pacific Northwest. In Colorado, teasel is usually found in relatively moist, disturbed situations but is moving into drier areas. Seeds can stay viable for at least 2 years. Seeds don't generally disperse far form the parent plant. Plants can regenerate The key to effective control of Common teasel is prevention. Eliminate seed production to decrease the spread of this forb, and continue to deplete the seed bank for four to six years. Reseeding areas with perennial grasses for several years will reduce an infestation. Mechanical and chemical control methods are effective when dealing with Common teasel. Details on the back of this sheet can help to create a management plan compatible with your site ecology. Common teasel is designated as a "List B" species in the Colorado Noxious Weed Act.

Rangeland, pasture, and riparian site recommendations Corn chamomile Identification and Management Identification and Impacts Corn chamomile (Anthemis arvensis L.) is an annual forb. The flowers are 0.75 inches in diameter and are borne at the ends of branched stems. Flowers resemble daisies with white ray flowers and yellow disk centers. The seeds are 10 ribbed with out glandular bumps. Leaves are alternate and finely dissected and mature plants are 10 to 30 inches tall. There is no odor when leaves are crushed, unlike Mayweed chamomile. Sterns are erect, smooth, and highly branched above. Corn chamomile germinates readily in the spring and fall. It has a dense, fibrous root system, which spreads rapidly during wet periods. Late summer and fall -germinated seedlings may overwinter as rosettes. In the spring, bolting commences with the elongation of the central stem. Overwintering plants flower in mid-May and spring germinated seedlings flower in June. Flowering stops after a killing frost, usually in October. The plant reproduces primarily by seeds. Habitats for Corn chamomile include: roadsides, ditches, in urban areas, waste places, cultivated fields, and pastures. It can grow in a wide range of soils but seems to prefer moist, poorly drained soils. Corn chamomile prefers moist areas and increases in abundance during years of above average precipitation. The key to effective control of Corn chamomile is prevention. Eliminate seed production to decrease the spread of this annual forb. Mowing is effective if done before the seed sets. Reseeding areas with perennial grasses for several years will reduce an infestation. Details on the back of this sheet can help to create a management plan compatible with your site ecology.

Rangeland, pasture, and riparian site recommendations Cutleaf teasel Identification and Management and savannas if allowed to become established. Identification and Impacts Cutleaf teasel (Dipsacus spp) is a biennial or sometimes monocarpic perennial forb. The plant grows as a basal rosette for a minimum of one year then sends up a tall flowering stalk and dies after flowering. The period of time in the rosette stage varies depending on the amount of time needed to acquire enough resources for flowering to occur. The flowers are almost white (taninsh) or white with spiny, awned bracts at the base. The floral bracts at the base of the head are generally longer than the head and wider than Common teasel. Flowering plants have large, oblong, opposite leaves that form cups and are prickly. The fruits are a four -angled achene, each contains a single seed. A single teasel plant can produce over 2,000 seeds. Rosette leaves are conspicuously veined, vary from somewhat ovoid in young plants to large and oblong leaves that are quite hairy in older plants. Stem leaves are simple, opposite, broad and feathering lobed. Mature plants can grow up to or over six feet tall. Cutleaf teasel blooms from July through September. Habitats for Cutleaf teasel include open, sunny habitats that range from wet to dry levels. It is generally found along irrigation ditches, rivers, abandoned fields, pastures, waste places, and forests. Teasels are an aggressive exotic species that have the capacity to take over prairies Seeds typically don't disperse far; most seedlings will be located around the parent plant. Parent plants often provide an optimal nursery site for new teasel plants after the adult dies. Dead adult plants leave a relatively large area of bare ground, formerly occupied by their own basal leaves, that new plants readily occupy. Seeds may have the capacity to be water -dispersed, which may allow seeds to be dispersed over longer distances. Immature seed heads of Cutleaf teasel are capable of producing viable seed. Lack of natural enemies allows teasel to proliferate. If left unchecked, teasel can quickly form large monocultures excluding all native vegetation. Cutleaf teasel is more aggressive than Common teasel. The key to effective control of Cutleaf teasel is prevention. Eliminate seed production to decrease the spread of this forb, and continue to deplete the seed bank for four to six years. Reseeding areas with perennial grasses for several years will reduce an infestation. Mechanical and chemical control methods are effective when dealing with Cutleaf teasel.

Rangeland, pasture, and riparian site recommendations Cypress spurge Identification and Management roadsides, Rights -of -Way, cemeteries, and gardens. Cypress spurge is popular in xeriscaping and rock gardens and generally does not occur on intensively cultivated soils. The soil seed reserve is estimated to be at least eight years. Identification and Impacts Cypress spurge (Euphorbia cyparissias) is a low growing perennial that overwinters as root and crown tissue. Cypress spurge reproduces by seed and lateral root buds. Leaves are linear, approximately 1/2 to 1 1/4 inches long and 1 to 2 mm wide. Upper stem leaves that occur near the inflorescence are yellow or yellowish -green in color. Leaves are stalkless, alternate, narrow and linear to lance -shaped. Stems are 4 to 32 inches high, hairless, green to yellowish green in color and branch in the upper portions. The leaves and stems emit a milky, toxic sap when broken. Flowers are yellowish -green usually turning reddish green towards maturity and are clustered in bunches at the ends of stems. The plants milky sap is an irritant and may cause dermatitis or rashes. Although sheep may eat it, the plant is toxic to horses and cattle. Animals should not be pastured where spurges grow. Humans should be careful and avoid contacting the plant with bare skin as it can cause skin irritation for some people. Cypress spurge is an invasive ornamental plant that is native to Eurasia. It prefers direct sunlight, but is tolerant to the shade. It commonly occurs in dry to moderately moist meadows, pastures, forest edges, The key to effective control of cypress spurge is preventing the establishment of viable plant communities. When establishment has occurred, there are different control methods to consider. Like most perennial plants, exhausting the nutrient reserves in the root system is important in controlling cypress spurge. Using a combination of mechanical and herbicide treatments in combination can achieve eradication over time. Cypress spurge is designated as a "List A species in the Colorado Noxious Weed Act. It is required to be eradicated wherever found in the State. For more information visit www.colorado.gov/ag/weeds and click on the Noxious Weed Management Program link.

Rangeland, pasture, and riparian site recommendations 1 Dalmatian toadflax Identification and Management a monoculture that severely reduces forage, productivity, biodiversity and wildlife habitat. Identification and Impacts Dalmatian toadflax (Linaria dalmatica) is a non-native, perennial forb introduced from the Mediterranean region as a folk remedy, fabric dye and ornamental. It reproduces both by seed and by extensive, creeping rhizomes. A single plant produces 500,000 seeds, most of which fall within 18 inches of the parent plant. Seeds can remain viable for at least 10 years. Dalmatian toadflax grows to 3 feet, and has bright yellow snapdragon -like flowers with an orange throat on elongated racemes. The alternate leaves are broad, with a thick, waxy cuticle and a bluish cast. Each leaf is heart -shaped and wraps the stem. Habitats for Dalmatian toadflax include disturbed open sites, fields, pastures, rangeland, roadsides, cropland and forest clearings. Infestations can begin in small disturbed sites, then spread even to rangeland and wildlife habitats in excellent condition. Dalmatian toadflax is a highly aggressive plant that can genetically adapt to varied environmental conditions and herbicide controls.

Identification and Impacts Dame's rocket (Hesperis matronalis) is a native Eurasia and is a biennial or short lived perennial forb belonging to the mustard family. The flowers are white to purple with four petals and are clustered in loose terminal stalks. Flowers appear from May to August and the plant can produce seeds and flowers on any flower cluster at the same time. The fruits are long, narrow and cylindrically shaped that contains many seeds. The seeds are small, angular, grooved and dark reddish brown. The seed pods are about 1 1/2 inches long and very narrow. Leaves are slightly hairy, alternate, and 2 to 4 inches long. The leaves are lance shaped with toothed margins. A mature plant ranges from 4 inches to 3 feet in height. Dame's rocket has a shallow fibrous root system. Habitats for Dame's rocket include: gardens, partly shaded woodlands, ditches, roadsides, pastures, rangelands, thickets, open woods, disturbed sites, and other areas that have moist well drained soils and full sun to light shade. Many people think that it is a native wildflower and is planted as a garden ornamental, however; the plant quickly escapes cultivation due to its prolific seed production. It is often sold in "native wildflower" mixes, so please be sure to check the contents of "native wildflower" seed mixes and The key to effective control of Dame's rocket is prevention. Locate and remove plants immediately before plants set seed to prevent the spread of Dame's rocket. Since the plant reproduces solely by seed, integrated management efforts must include the elimination of seed production and depletion of seed bank.

Seedlings have finely divided leaves Diffuse knapweed Identification and Management on dry sites and rapidly invades and dominates disturbed areas. Once established, diffuse knapweed outcompetes and reduces the quantity of desirable native species such as perennial grasses. As a result, biodiversity and land values are reduced, and soil erosion is increased. Identification and Impacts Diffuse knapweed (Centaurea diffusa) is a non-native biennial forb that reproduces solely by seed. A biennial is a plant that completes its lifecycle within two years. During the first year of growth, diffuse knapweed appears as a rosette in spring or fall. During the second year in mid to late spring — the stem bolts, flowers, sets seed, and the plant dies. Once the plant dries up, it breaks off at ground level and becomes a tumbleweed which disperses the still viable seeds over long distances. A prolific seed producer, diffuse knapweed can produce up to 18,000 seeds per plant. Therefore, the key to managing this plant is to prevent seed production. Diffuse knapweed can grow 1 to 3 feet tall, and is diffusely branched above ground. This gives the plant a ball - shaped appearance and tumble -weed mobility when broken off. Leaves are small, and are reduced in size near the flowering heads. Flowers are mostly white, sometimes purple, urn -shaped, and are located on each branch tip. Bracts that enclose the flowerheads are divided like the teeth of a comb, and are tipped with a distinct slender spine. Upon drying, the bracts become rough, rendering them injurious to the touch. Flowers bloom July through August. Seed set usually occurs by mid-August. Diffuse knapweed tends to invade disturbed, overgrazed areas. Other habitats may also include rangeland, roadsides, riparian areas, and trails. It is a tough competitor The key to effective control of Diffuse knapweed is to prevent the plant from flowering and going to seed. An integrated weed management approach dealing with Diffuse knapweed is highly recommended. There are many options of mechanical, chemical, and biological controls, available. Details on the back of this sheet can help to create a management plan compatible with your site ecology. Diffuse knapweed is designated as a "List B" species on the Colorado Noxious Weed Act.

White flowers. 2. Grows erect 10- 24" in height. 3. Leaf is 3/4-4" long with blunt end and fine white hairs. Identification and Impacts Hoary cress (Cardaria draba), commonly known as whitetop, is a creeping perennial that is a member of the mustard family and native to Europe. The stems, in the rosette stage, may grow up to 2 inches in height and produce grayish -green leaves that are lance shaped. The leaves are alternate and 3/4 to 4 inches long. The upper leaves have 2 lobes that clasp the stem. The plant has numerous small, white flowers with 4 petals on stalks radiating from a stem. Seed capsules are heart - shaped with two small, flat, reddish brown seeds. One plant can produce from 1,200 to 4,800 seeds. The plants emerge in early spring with stems emerging from the center of each rosette in late April. Hoary cress flowers from May to June and plants set seed by mid -summer. Habitats for Hoary Cress include: fields, waste places, meadows, pastures, croplands and along roadsides. It is typically found on unshaded, generally open areas of disturbed ground. It generally does better with moderate amounts of precipitation and grows well on alkaline soils. The key to effective control of Hoary cress is prevention. Preventing the encroachment of these weeds is the most cost-effective management. Preventing invasions by limiting seed dispersal, monitoring and using weed free hay, and quarantine animals that may have grazed in infested areas. Beyond prevention, the key is early detection when infestations are small, and aggressive management. Integrated Weed Management is required for proper control. Details on the back of this sheet can help to create a management plan compatible with your site ecology. Hoary cress is designated as a "List B" species in the Colorado Noxious Weed Act.

Panicles of reddish -purple flowers with 5 petals and 5 soft, hairy sepals. 2. Velcro -like seeds with 4 nutlets. Identification and Impacts Houndstongue (Cynoglossum officianale)is a short lived perennial or biennial forb. It produces rosettes in the first year, and bolts a stout, erect stem that is 1 to 4 feet tall, by mid -summer of the second year. Then it flowers and produces fruit. Flowers are reddish -purple (occasionally white) and droop slightly from densely clustered panicles. The five rounded petals are cupped by five sepals covered with long, soft white hairs. Flowering occurs May to July. The simple leaves are lance or oblong shaped, with a smooth edge and no teeth or lobes. Leaves are alternate, 1 to 12 inches long and 1 to 3 inches wide. The leaf tip is sharply pointed, like a hound's tongue, yet are covered with long -soft white hairs. Leaves often appear dusty and insect -ridden. A thick, dark, woody taproot can reach 3 to 4 feet deep. Reproduction is solely by seeds. Seeds are 4 prickly teardrop - shaped nutlets, which are packed in a pyramid -shaped receptacle. Most seeds fall close to the parent plant, but the seeds can travel great distances. The seeds have barbs like Velcro, with a hooked tip that clings to animals, clothing and machinery. A mature plant can produce 2,000 seeds. Seed viability is 1 to 3 years. Houndstongue is poisonous. Toxic pyrrolizidine alkaloids in Houndstongue stop liver cells from reproducing. Livestock and wildlife may live up to six months after ingesting a lethal dose. Though the plant has a distinctive odor that repels animals, it is more palatable when dried. Animals rarely eat it unless it is dried and mixed with hay. Houndstongue's toxicity effects horses and cattle more severely, sheep seem more resistant. Burs will reduce the value of sheep wool if present. Habitats for Houndstongue are open to shady, moist, disturbed areas, along trails, roadsides, fields, pasture, rangeland, along the edge of forests, sand dunes and ditch banks. Houndstongue prefers moist areas, but often grows on sandy or gravelly alkaline soil up to 9,000 feet elevation. Areas with more than 10% bare ground are particularly vulnerable to Houndstongue invasions. The key to effective control of Houndstongue is preventing establishment and to prevent seed production. Planting competing and desirable grasses anc. forbs can be effective. Helping with reestablishment of disturbed sites. An integrated weed management approach can also be successful. Chemical, mechanical, and biological controls can be effective when dealing with Houndstongue. Details on the back of this sheet can help to create a management plan compatible with your site ecology. Houndstongue is designated as a"List B" species in the Colorado Noxious Weed Act.

In some cases when found in the wheat fields, certifications will not be given for several years, until it can be proven that Jointed goatgrass is no longer in the field. Jointed goatgrass and Winter wheat will cross pollinate producing a sterile hybrid, causing more issues. Identification and Impacts Jointed goatgrass (Aegilops cylindrica) is a winter annual that is native to southern Europe and Russia. The plants can grow as a single or multiple stems or tillers, it will grow 15 to 30 inches tall. Leaves are simple and alternate. The auricles of the leaf are at the base. Leaf blades are hairy and are 1/8 to 1/4 of an inch in width. The cylindrical spikes, contain 2 to 12 spikelets. The spikelets are 1/2 inch long and contain 1 to 3 viable seeds. The spikelets appear to be "jointed," they fit into the contour of the rachis. On top of the spikelets the glumes will appear with long awns. In the seedling stage, Jointed goatgrass looks similar to Winter wheat. Habits for Jointed goatgrass includes, grasslands, wheat fields, fence rows, waste places, roadsides, alfalfa fields, and pastures. When found in Winter wheat fields, jointed goatgrass can contribute to a significant economic loss. Jointed goatgrass seeds are similar to size and weight of small grain seeds, such as Winter wheat, making separation almost impossible and costly. Once Jointed goatgrass seed has been determined to The key to effective control of Jointed goatgrass is preventing the establishment in fields by cleaning equipment prior to moving into the fields, preventing Jointed goatgrass going to seed, and rotating crops to spring grown plants. Jointed goatgrass can be controlled using a variety of methods. Details on the back of this sheet can help to create a management plan compatible with your site ecology. Jointed goatgrass is designated as a "List C" species on the Colorado Noxious Weed Act. It is required to be either eradicated, contained, or suppressed depending on the local jurisdictions managing this species.

Rangeland, pasture, and riparian site recommendations Leafy spurge Identification and Management rapidly growing, and extensive root system makes leafy spurge very difficult to manage. Develop a management plan that uses several control methods that are compatible with your site. Identification and Impacts Leafy spurge (Euphorbia esula) is a non-native deep-rooted perennial that spreads by seed and extensive, creeping roots. The roots can extend as deep as 30 feet into the soil and are extremely wide -spreading. The roots are brown and contain numerous pink buds that generally produce new shoots or roots. Leafy spurge can grow from 1 to 3 feet in height. The stems are smooth, pale green, and thickly clustered. Leaves are alternate, narrow, linear, and 1 to 4 inches long. The flowers are very small and yellowish -green. They are enclosed by very visible yellowish -green, heart -shaped bracts. The entire plant contains white, milky sap that exudes readily upon stem or leaf breakage. This sap can damage eyes and sensitive skin. Leafy spurge is one of the earliest plants to emerge in the spring. Flower clusters develop 1 to 2 weeks after stem emergence which is from mid-April to late May. One large leafy spurge plant can produce up to 130,000 seeds. Three -sided seed capsules explode when ripe and project the seeds up to 15 feet away from the parent plant. Leafy spurge has adapted to a wide variety of habitats in the state and is very competitive with other plant species. Where it becomes established in rangeland, pasture, and riparian sites, it crowds out practically all other vegetation. The competitive, The most effective method of control for Leafy spurge is to prevent its establishment through proper land management. Maintain healthy pastures and rangeland and continually monitor your property for new infestations. New infestations are much more easily controlled than established infestations. Details on the back of this sheet can help to create a management plan compatible with your site ecology. Leafy spurge is designated as a "List B" species on the Colorado Noxious Weed Act. It is required to be either eradicated, contained, or suppressed depending on the local infestations. On the back of this sheet are leafy spurge management recommendations.

Bushy mature plants are 0.5 to 2 ft. tall. 2. Leaves have foul smell and are divided several times into narrow segments. 3. White ray flowers. Identification and Impacts Mayweed chamomile (Antbemis cotula) is a bushy annual that can adapt to various conditions and is native to Europe. The seeds are 10 ribbed with small glandular bumps. Mayweed chamomile is a prolific seed producer, producing more than 960,000 seeds per plant. The seeds viability in soil range from 4 to 6 years. The leaves are finely dissected, alternate, and approximately 0.75 to 2.5 inches long and 1 inch wide. Leaves may have some short hairs and emit an unpleasant odor. Flowers are solitary and borne at the ends of branches. They are 0.75 to 1.25 inches in diameter with 12 white ray flowers and yellow disk centers. The white ray flowers are in bloom from June through September. Mature plants grow from 0.5 to 2 feet tall and are highly branched. Contact with Mayweed chamomile can cause skin rashes, blistering of livestock muzzles and irritated mucus membranes of grazing livestock. The blistering can cause animals to reduce grazing resulting in weight loss and reduced milk production. In addition, it may impart a strong flavor to the milk of dairy animals. Habitats for Mayweed chamomile include roadsides, ditches, in urban areas, waste places, cultivated fields, and pastures. It can grow in a wide range of soils but seems to prefer moist, poorly drained soils. Mayweed chamomile prefers moist areas and increases in abundance during years of above average precipitation. The key to effective control of Mayweed chamomile is prevention. Eliminate seed production to decrease the spread of this annual forb. Mowing is effective if done before the seed sets. Reseeding areas with perennial grasses for several years will reduce an infestation. Details on the back of this sheet can help to create a management plan compatible with your site ecology.

Rangeland, pasture, and riparian site recommendations Meadow knapweed Identification and Management Identification and Impacts Meadow knapweed (Centaurea pratensis) is a perennial that grows from a woody crown. The upright stems, grow from 20 to 40 inches tall and branch near the middle. Flower heads are solitary at tips of the branches, pink to purple in color, and 3/4 of an inch in size. Bracts are light to dark brown with papery -fringed margins. Lower leaves are lobed and upper leaves are linear. The leaves grow up to 6 inches long and more than 1 inch wide. Meadow knapweed primarily reproduces by seed, but root and crown fragments re -sprout when disturbed by heavy equipment or cultivation. Meadow knapweed seeds are carried in rivers, streams, or irrigation water, in hay or by vehicles along roadsides. It is an attractive plant which some people plant as a garden ornamental. The seed viability for meadow knapweed is unknown. The site must be monitored for at least 10 years after the last flowering adult plants have been eliminated and treatments repeated when necessary. Habitat for meadow knapweed include moist sites, irrigated pastures, moist meadows, river banks, streams, irrigation ditches, roadsides, and openings in forested areas. The plant is native to Europe where originally it was introduced (a cross between black and brown knapweed) as a potential forage species, but it has low palatability to grazing animals. Meadow knapweed outcompetes native plants and pasture species and reduces available forage for wildlife and livestock. It is not palatable or nutritionally sufficient for livestock and disrupts wetland habitat by displacing native plant species. The key to effective control of meadow knapweed is preventing the establishment of plant communities by maintaining healthy native plant populations. If meadow knapweed is present, using a combination of control methods including; mechanical and herbicides to eradicate populations is effective. Meadow knapweed is designated as a "List A species in the Colorado Noxious Weed Act. It is required to be eradicated wherever found in the State.

Rangeland, pasture, and riparian site recommendations 1 Mediterranean sage Identification and Management Identification and Impacts Mediterranean sage (Salvia aethiopis) is a biennial that is an erect, coarse biennial or short- lived perennial, with a stout taproot. First year rosettes are blue-green, and are covered with woolly white hairs. Second year plants produce more leaves with a flowering stem. Leaves have a pungent odor when crushed. The flower stem can grow 2 to 3 feet tall and branch 2 to 3 feet wide resembling a candalabra. The stem breaks off in the fall and forms a tumbleweed dispersing thousands of seeds. Mature plants can produce 100,000 seeds each. The flowers are white to yellowish -white and appear in clusters. Mediterranean sage is native to the Mediterranean region and northern Africa. Mediterranean sage invades primarily rangeland, but will easily invade riparian areas, forests, roadsides, and dry pastures. This invasive ornamental plant prefers south -facing slopes in loose, gravelly, well drained soils. Mediterranean sage initially invades disturbed sites, but quickly spreads to non -disturbed and natural sites. It adapts to a wide variety of environmental conditions and quickly displaces native vegetation. The plant is unpalatable to most grazing animals and is capable of forming dense monocultures. The seed viability for Mediterranean sage is unknown. The site must be monitored for at least 10 years after the last flowering adult plants have been eliminated and treatments repeated when necessary. The key to effective control of Mediterranean sage is preventing the establishment of plant communities through the use of sound land management practices. Maintain healthy pastures and rangeland and continually monitor your property for new infestations, especially near current known infestations since tumbleweed mobility of this plant can spread the seeds far and wide.

A biennial is a plant that completes its lifecycle within two years. During the first year of growth, musk thistle appears as a rosette in spring or fall. During the second year in mid to late spring, the stem bolts, flowers, sets seed, and the plant dies. Musk thistle produces many flower heads. The terminal, or tallest, shoots flower first, then lateral shoots develop in leaf axils. A robust plant may produce 100 or more flowering heads. A prolific seed producer, musk thistle can produce up to 20,000 seeds per plant, only one-third being viable. Because musk thistle reproduces solely from seed, the key for successful management is to prevent seed production. Musk thistle can grow up to 6 feet tall. The leaves are spiny, waxy, and dark green in color with a light green midrib. The flowers are purple, large in size (1.5 to 3 inches in diameter), nodding, and terminal. The flowers are surrounded by numerous, lance -shaped, spine -tipped bracts. You can expect to see flowers from late May and June. Seed set usually occurs in June or July and effective management options will then become limited. Habitats for Musk thistle include disturbed, overgrazed areas. Once a pasture is infested, the livestock carrying capacity for that area is significantly decreased. The plant may also occur on rangeland, roadsides, ditches, riparian areas, and trails. The key to effective control of Musk thistle is to prevent the plant's seed production, Planting desirable grasses and forbs to out compete Musk thistle can also be effective. Dense Musk thistle stands can be treated by spot treatments of herbicides and by a persistent mechanical program. Details on the back of this sheet can help to create a management plan compatible with your site ecology. Musk thistle is designated as a "List B" species in the Colorado Noxious Weed Act. It is required to be either eradicated, contained, or suppressed depending on the local infestations.

Alternatives to planting myrtle spurge include native plants such as sulphur flower (Erigonum umbellatum), Kinnikinnick (artcostaphylos uvursr), or creeping mahonia (Mahonia repens). The soil seed reserve of myrtle spurge is estimated to be eight years. The site must be monitored for at least nine years after the last flowering adult plants have been eliminated and treatments repeated when necessary. Identification and Impacts Myrtle spurge (Euphorbia myrsinites) is a low growing perennial with trailing fleshy stems. The leaves are fleshy, blue-green and alternate. Flowers are inconspicuous with yellow -green, petal -like bracts that appear from March to May. Myrtle spurge spreads by seed and plants are capable of projecting seeds up to 15 feet. The plant grows from a taproot, with new stems emerging in early spring and dying back in the winter. Plants can grow up to 8- 12 inches high and 12-18 inches in width. Myrtle spurge contains a toxic, milky sap which can cause severe skin irritations, including blistering. This plant is poisonous if ingested; causing nausea, vomiting and diarrhea. Wearing gloves, long sleeves, shoes, and eye protection is highly recommended when in contact with myrtle spurge, as all plant parts are considered poisonous. Myrtle spurge is an invasive ornamental that is native to Eurasia. It is popular with xeriscapes and rock gardens, preferring sunny to partly sunny areas and well drained soils. Myrtle spurge rapidly escapes gardens and invades sensitive ecosystems, out competing native The key to effective control of myrtle spurge is to remove plants prior to seed set and to detect and remove new populations in natural areas early on. Small areas can be easily removed by mechanical means but should be done early to prevent triggering seed launching. Details on the back of this sheet can help to create a management plan compatible with your site ecology. Myrtle spurge is designated as a "List A' species in the Colorado Noxious Weed Act. It is designated for statewide eradication. For more information visit www.colorado. gov/ag/weeds and click on the Noxious Weed Management Program.

It is a rhizomatous, creeping, short-lived perennial that grows 10 inches to 2 feet tall. The basal and lower leaves are spoon - shaped, toothed, and with long petioles (leaf stem). The upper leaves are narrow, toothed, and clasp the stem. Flowers bloom between June and August. The flowers are 1 to 3 inches in diameter, with 15 to 3o white ray flowers, and mostly solitary. The phyllaries beneath the flower head are green with a dark brown margin. One flower head can produce up to 200 seeds. Oxeye daisy spread vegetatively from roots, root fragments, or by seed. Seeds may be viable up to 38 years or more. Infestation sites needs to be monitored for at leastlo years after the last flowering plant has been eliminated and treatments repeated when necessary. Ornamental Shasta daisy (Leucantheum x superbum) is not an aggressive invader and looks similar to oxeye daisy, but it is 6 to 12 inches taller and has larger flowers. 0 xeye daisy is an strong competitor. It forms dense stands that reduce native plant diversity. It degrades pastures and natural areas because cattle and wildlife avoid feeding on oxeye daisy. Heavy infestations may reduce nutrient cycling due to a shallow root system and create areas of bare soil, thus increasing soil erosion. Habitats for oxeye daisy included mountain meadows, grasslands, pastures, streams, gardens, waste grounds, railway, and roadsides. Oxeye daisy typically grows in high elevations, up to 11,000 feet in Colorado. The key to effective control of oxeye daisy is education and prevention. Oxeye daisy has been included in many different seed mixes, thus consumers should carefully read the label prior to planting so- called "native wildflower" mixes. Homeowners and land managers often overlook the impacts and the need to manage this weed because of the plant's attractiveness.

Rangeland, pasture, and riparian site recommendations Perennial pepperweed Identification and Management and floodplains. If introduced, it can also invade roadsides, hay and alfalfa fields and rangeland. It readily invades disturbed and bareground areas. It can thrive in either low or high -saline soils. Large monocultures and dense litter layers prevent native plants from regenerating. Pepperweed displaces native plants and wildlife habitats, reduces food quality for wildlife and reduces agricultural and pasture production. Identification and Impacts Perennial pepperweed (Lepidium latifolium) is an extremely invasive perennial forb introduced from Europe and Asia in 1900 as a containment in sugar beet seed. Pepperweed reproduces both by seed and vegetatively by roots and shoots. Root fragments as small as 0.5 inch can grow into new plants. A serious threat, pepperweed alters ecosystems by acting as a "salt pump" absorbing salts from deep in the soil. The plant then excretes the salt through the leaves and deposits it on the surface soil. Since most desirable plants do not tolerate high saline concentrated soils, the entire plant composition and diversity of the area changes. Growing 1 to 5 feet high, pepperweed has tiny white flowers. The flowers have four spoon -shaped petals in dense, rounded clusters on branch tips of erect stems. Stems emerge from deep, thick, woody root stocks that can penetrate 10 feet into the soil. Leaves of the mature plant are alternate, and lance or oblong in shape with serrated edges that are slightly wavy. They are glabrous (not hairy) and green to gray -green in color, with a distinctive white midrib. Upper leaves are smaller than basal leaves and have no stalks. Perennial pepperweed invades a wide variety of habitats, from intermountain, mountainous areas and marshes. It is frequently found in riparian areas, wetlands, marshes, irrigation ditches, canals, Perennial pepperweed rarely produces seedlings in the field, even with extensive seed crops. Research is underway, but the lack of seedlings may be due to seeds rapidly losing viability in the field (but not in the laboratory). Reproduction is primarily from deep, perennial roots and root pieces which break off and sprout new plants. However, preventing seed production is still recommended until further research is done. The key to effective control of Perennial pepperweed is preventing establishment of large populations. Early detection and removal of plants if found, is the key to prevention. Planting desirable and competing grasses and forbs can aid in limiting the spread of Perennial pepperweed. Herbicide treatments are a good option if used during the bud to flowering stage of the plant. Once established, containment is key. Details on the back of this sheet can help to create a management plan compatible with your site ecology. Perennial pepperweed is designated as a "List B" species in the Colorado Noxious Weed Act. It is required to be either eradicated, contained, or suppressed depending on the local infestations.

Identification and Impacts plumeless thistle (Carduus acanthoides) is a winter annual or biennial that is native to Europe and Asia. Plumeless thistle rosettes have wavy leaves with yellow spines along the white -colored leaf margins. The stems are covered with leaf -like, winged spines that extend up to the flowering heads. The flower heads, in clusters of 2 to 5, are alone at the end of the branches. They are purple to dark red in color and are 1/2 to 1 inch in diameter. Leaves are alternate, stalk -less, hairy underneath and blend into the stem. Mature plants can grow taller than 5 feet and can produce upwards of 9,000 seeds. Habitats for Plumeless thistle include pastures, fields, disturbed lands, logged -over areas, river valleys, along roadsides and in native grasslands. Plumeless thistle out competes native species and forage crops. It is one of the most aggressive thistles, due to its high seed production. Plumeless thistle is unpalatable to livestock and it may accumulate nitrates. PTants over winter and grow from seeds and rosettes. The seed viability for Plumeless thistle is unknown. The site must be monitored for at least 10 years after the last flowering adult plants have been eliminated and treatments repeated when necessary.

They appear from June to July. The fruit matures in August - September and is flat, small and grayish -green in color. Habitats for Poison hemlock include streams, rivers, irrigation and roadside ditches, crop and pasturelands, as well as disturbed sites. All parts of the plant are poisonous, they contain alkaloids. Animals do not eat the plant,unlessfood isscarce. Ingestion of 0.25-0.30% of an animals body weight is lethal. Poisoning of humans has occurred, the plant can easily be confused with members of the carrot family. Consumption in large quantities can be fatal. The key to effective control of Poison hemlock is prevention and containment. Identified early enough, pulling theta prootwhensoil is moist can be an effective control method.

There are many planting alternatives that are better suited to Colorado and beneficial to wildlife. Alternatives include spotted gayfeather, Rocky Mountain Penstemon, beebalm, purple coneflower, and Colorado Columbine. For more information refer to Colorado Native Plant Society's website, www. conps.org. Identification and Impacts Purple loosestrife (Lythrum sahcarla) is a non-native, tap - rooted, perennial forb. It is native to Europe and was introduced to North America as an ornamental plant for gardens. It has escaped into natural areas such as streambanks and shallow ponds. Purple loosestrife reproduces primarily by seed. A single, mature plant can produce up to three million seeds per year. The seeds can remain viable in the soil for 5 to 20 years. Pieces of roots or stems also can produce new plants. Purple loosestrife produces multiple four-sided stems that can grow two to eight feet tall. Leaves are two to five inches long, lance - shaped and whorled on the stems. Flowers are tightly grouped in long, vertical heads; they bloom from the bottom up. They are pinkish -purple in color, about one inch long, and have five to seven petals. Flowers appear from late June through September. Purple loosestrife can be found along riverbanks, ditches, and wet meadows throughout the state. Infestations rapidly replace native vegetation, can impede water flow in canals and ditches, and have little wildlife habitat value. Infested wetlands eventually become a monoculture of loosestrife. lf purple loosestrife is growing in your garden, remove plants The key to effective control of purple loosestrife is early detection when infestations are small. It is fairly easy to control small numbers of loosestrife plants when the seed bank in the soil is low. Eradicating large populations is much more difficult. Persistent management and monitoring of site is a long-term program to ensure eradication. Small loosestrife infestations should be eradicated by hand-pulling/cutting in combination with herbicide application. Details on the back of this sheet can help to create a management plan compatible with your site ecology. Purple loosestrife is designated as "List A' species on the Colorado Noxious Weed Act. It is required to be eradicated wherever found in the State.

Leaves are silvery white with dense scales. 2. Flowers have 4 small sepals and are light yellow clusters. 3. Red -yellow fruits on mature plants. Rangeland, pasture, and riparian site recommendations Russian olive Identification and Management fields and open areas. Russian -olive can out compete native vegetation, interfere with natural plant succession and nutrient cycling, and tax water reserves. Because Russian -olive is capable of fixing nitrogen in its roots, it can grow on bare, mineral substrates and dominate riparian vegetation. Although Russian -olive provides a plentiful source of edible fruits for birds, ecologists have found that bird species richness is actually higher in riparian areas dominated by native vegetation. Identification and Impacts Russian olive (Elaeagnus angustifoilia) is a perennial tree or shrub that is native in Europe and Asia. The plant has olive - shaped fruits, silver color at first then becoming yellow -red when mature. Russian olive can reproduce by seed or root suckers. Seeds can remain viable for up to 3 years and are capable of germinating in a broad range of soil types. Spring moisture and slightly alkaline soil tend to favor seedling growth. The plants extensive root system, sprouts root suckers frequently. The stems can reach up to 30 feet in height with branches and trunks that have 1 to 2 inch thorns. Leaves are 2 to 3 inches long, alternate, narrow, have simple blades, and are untoothed. The lower surface is silvery white with dense scales, while the upper surface of the leaf is light green in color. Flowers are 4 small sepals in light yellow clusters, fragrant, and appear May through June. Russian olive twigs are flexible, reddish, and have surfaces coated with gray and scaly pubescence, becoming smooth. Once thought to be a beneficial windbreak tree, it since has been deemed detrimental to the environment. Russian olive can grow in a variety of soil and moisture conditions, but prefers open, moist riparian zones. It is shade tolerant and can be found along streams, The key to effective control of Russian olive is preventing establishment of the trees or shrubs. If plants are already present, control options include cut -stump treatments and mechanical mowing. These treatments are dependant on size and location of the plant. Details on the back of this sheet can help to create a management plan compatible with your site ecology. Russian olive is designated as a "List B" species in the Colorado Noxious Weed Act. It is required to be either eradicated, contained, or suppressed depending on the local infestations.

It's heavy use of water has contributed to the intensity of the drought. Identification and Impacts Saltcedar, or tamarisk (Tamarix spp.), is a non-native deciduous evergreen shrub or small tree that grows from 5 to 20 feet tall. The bark on saplings and stems is reddish -brown. The leaves are small, scale -like and bluish -green in color. Tiny pink to white flowers have five petals and grow on slender racemes. Saltcedar reproduces by seeds as well as vegetatively. A mature plant can produce up to 600,000 seeds per year. Seeds are viable for up to 45 days under ideal conditions. Saltcedar buds break dormancy in February or March. Flowering occurs anytime between April and August. Ideal conditions for saltcedar seedling survival are saturated soil during the first few weeks of life, a high water table, and open sunny ground with little competition from other plants. Saltcedar was introduced from central Asia, northern Africa, and southern Europe for ornamental purposes and for stream bank stabilization. It is now widespread in the United States. Saltcedar crowds out native stands of riparian and wetland vegetation. Saltcedar increases salinity of surface soil, rendering the soil inhospitable to native plant species.

Identification and Impacts Scentless chamomile (Matricaria perforata) is a an annual, biennial, or short-lived perennial forb that is native to Europe. Seedlings emerge in spring and can produce a dense mat, out competing other species. Seeds and flowers are continually being formed. Each flower head can produce 300 seeds and a single plant can produce 300,000 seeds. The flowers are white in color, 3/4 inches and are daisy like flowers that are solitary on each stem. Flowers have a yellow central disk surrounded by white petals. Leaves are alternate, fernlike, finely divided, and odorless when crushed. The stems can reach 6 inches to 3 feet tall and have numerous branches. Habitats for Scentless chamomile include: hayfields, pastures, roadsides, streambanks, fencelines, and moist areas such as drainages. There are limited control options in an agricultural setting because more spray is needed that can be used with crops. In addition, blistering on livestock muzzles and irritation to mucous membranes are another agricultural concern. The key to effective control of Scentless chamomile is prevention and preventing seed production.

Abiennial is a plant that completes its lifecycle within two years. During the first yearofgrowth,Scotch thistleappears as a rosette in spring orfall. Rosettes can be Ito2feetindiameter. During the second year in mid to late spring the stem bolts, flowers, sets seed, and the plant dies. A prolific seed producer, Scotchthistlecan produce up to 14,000 seeds per plant. Scotch thistle can grow up to 12 feet tall. Stems are numerous, branched, and have broad, spiny wings. The leaves of species acanthium are large, grayish - green, spiny, and covered with fine dense hair giving the leaf a woolly appearance.The leavesofthespecies tauricum are similar in size, but are not hairy, smooth and bright green. On both species, the leaves have a distinct mid -rib. The flowers are violet to reddish in color, numerous (70-100/plant), and are surrounded by spine -tipped bracts. The plants flower from mid-June to September. Duetotherobust,spinynatureof Scotch thistle, this plant can act as a living barbed wirefence, making areasimpassibleforwildlife,livestock, and people. Scotch thistle invades rangeland, overgrazed pastures, roadsides, and irrigation ditches. It also prefers high -moist soil areas adjacent to creeks and rivers. The key to effective control of Scotch thistle is maintaining healthy pastures and rangeland, guarding against disturbance or overuse, and as with most biennials limit seed production. To reduce seed production, plants with buds or flowers should be collected and immediatelydisposedofordestroyed. Chemical control is most effective when plantsareinrosettestage,spring or early fall. Mechanical controls can be used to eliminate small patches or plants in a later growth stage. Details on the back of this sheet can help to createa management plan compatible with your site ecology.

Spotted knapweed cangrow up to 4 feet tall on erect, ridged stems that are openly branched on the upper half of the plant. Urn -shaped flowers are Spotted knapweed solitary on the end of each branch tip. Flowers are pink to purple, and rarely white. Leaves are small, oblong in shape and pinnately divided. Multiple rosettes can form on a single spotted knapweed taproot crown. Flowers bloom June to October and seed set usually occurs by mid-August. invader. Spotted knapweed and diffuse knapweed infestations often occur together in Colorado. Once established, Spotted knapweed reduces livestock and wildlife forage by out competing native species. The most effective method of control for Spotted knapweed is to prevent seed production and its establishment through proper land management. Maintain healthy pastures and rangeland and continually monitor your property for new infestations. If Spotted knapweed is already established, using an integrated weed management approach proves to be effective. Details on the back of this sheet can help to create a management plan compatible with your site ecology. Spotted knapweed is designated as a "List B" species on the Colorado Noxious Weed Act.

Long, right- angled hairs on the leafstalks and stems Rangeland, pasture, and riparian site recommendations Sulfur cinquefoil Identification and Management shrubby areas, open forest and logged areas, roadsides, clear cuts, waste areas, abandoned fields, and other disturbed sites. This plant is now becoming common in areas such as natural grasslands, shrubby areas, and open canopy forests. Sulfur cinquefoil grows on dry sandy, gravelly, and rocky soils, and prefers climates that receive from 13 to 50 inches of mean annual precipitation. Identification and Impacts Sulfur cinquefoil (Potentilla recta) is a perennial forb that is native to Eurasia. The flowers are pale yellow with 5 heart -shaped petals and are slightly longer than the 5 enclosing green sepals and 5 small bracts. Sulfur cinquefoil's flowers appear from May to July with peak flowering generally occurring in late June. Each flower produces numerous small seeds that are slightly flattened and 1.3 mm long. The seeds are comma- shaped, brownish -purple in color and covered with a net -like pattern of veins. Seeds remain viable in the soil for at least three years. Leaves are numerous, alternate and compound with 5 to 7 leaflets having toothed edges. Leafstalks have conspicuous perpendicular hairs and leaves appear green on the underside. The erect stems are single to several, with few (or none) slender branches and are 12 to 28 inches in height that grow from well developed rootstock. The plant has a single taproot and may have several shallow, spreading branch roots but no rhizomes. Sulfur cinquefoil is unpalatable to grazing animals and is avoided for the most part. The low preference is believed to be a result of a high concentration of phenolic tannins (acidity) in the leaves and stems. The plant has a long life span and twenty year old plants are not uncommon. Habitats for Sulfur cinquefoil include: open grasslands, The key to effective control of Sulfur cinquefoil is an integrated weed management approach. Properly identifying sulfur cinquefoil is imperative, since it resembles the native cinquefoils. Hand pulling or digging when infestations are small and the soil is moist, is effective. What has proven to be the most effective control method for Sulfur cinquefoil, has been the use of selective herbicides. Details on the back of this sheet can help to create a management plan compatible with your site ecology. ulfur cinquefoil is designated as a "List B" species in the Colorado Noxious Weed Act. It is required to be either eradicated, contained, or suppressed depending on the local infestations.

Rangeland, pasture, and riparian site recommendations Yellow starthistle Identification and Management Yellow starthistle is fatally poisonous to horses (causing chewing disease) and is considered poor forage for all livestock and wildlife. It also destroys native plant communities. The seed bank of yellow starthistle is not completely understood. The site must be monitored for at least 15 years after the last flowering adult plants have been eliminated and treatments repeated when necessary. Identification and Impacts Yellow starthistle (Centaurea solstitialis) originated from Northern Spain. It is a winter annual that is blue-green in color, has a vigorous taproot, and produces bright yellow flowers with sharp, stiff spines surrounding the base of the flower that extend up to 3/a of an inch long. Yellow starthistle grows from 1 inch tall to 4 feet tall. Basal leaves are 1-3 inches long and deeply lobed while upper leaves are smaller and narrower. Stems appear winged and both stem and leaves have a slight whitish nap covering them. Yellow starthistle spreads by seed with a single large plant producing up to 100,000 seeds. Plumed and plumeless seeds disperse at different times. Yellow starthistle typically germinates in the fall with increased moisture, overwinters as a seedling, and forms its rosette beginning in March through May. It can however, germinate extremely fast with optimal conditions throughout the entire summer (16 hours or less with — 70 degrees F and ample moisture). Flowering generally occurs from June to September and often later. Habitats for yellow starthistle include rangelands, pastures, roadsides, wastelands, and lower elevations. Over utilized grasslands are particularly susceptible to invasion. The key to effective control of yellow starthistle is to prevent seed set from occurring in existing populations, monitoring your land for new infestations frequently, treating newly detected invasions rapidly, and preventing new introductions from occurring. Details on the back of this sheet can help to create a management plan compatible with your site ecology. Yellow starthistle is designated as a "List A" species in the Colorado Noxious Weed Act. It is designated for statewide eradication. For more information visit www.colorado.gov/ ag/weeds and click on the Noxious Weed Management Program.

Yellow flowers that are like snapdragons with deep orange centers. 2. Stems that are woody at the base and smooth to the top. Identification and Impacts Yellow toadflax (Linaria vulgaris) is a perennial escaped ornamental plant that is native to the Mediterranean region. The leaves are narrow, linear, and 1 to 2 inches long. The stems are woody at the base and smooth toward the top. Sparingly branched and 1 to 3 feet tall. The showy snapdragon -like flowers are bright yellow with a deep orange center and have a spur as long as the entire flower. It develops an extensive root system, making control options varied. Yellow toadflax displaces desirable plant communities reducing ecological diversity and rangeland value. Decreases forage for domestic livestock, some big game species and decreases habitat for associated animal communities. The plant is known to be mildly poisonous to cattle. Goats and sheep have been known to graze the plants with little effect. Habitats for Yellow toadflax include roadsides, vacant lots, gravel pits, fields, waste areas, other disturbed sites and rangeland. It has adapted to a variety of site conditions, from moist to dry and does well in all types of soil. The plant can even establish in areas of excellent condition in natural disturbances or small openings. The key to effective control of Yellow toadflax is prevention and integrating as many management strategies as possible. Prevention is always desirable when dealing with Yellow toadflax. Early detection and eradication can keep populations from exploding, making more management options available.

This plan will cover the re -contouring, reseeding, noxious weed treatment, stormwater mitigation and monitoring, and final reclamation of the Cottonwood Pass Pipeline Right - of -Way (ROW). The reclamation of disturbed land is a critical component when restoring functions and values of an ecological system. Rehabilitation of the disturbed area assists natural ecological processes toward a self -promoting system. Once a self-supporting environment has been established, the natural processes can take over and continue the rehabilitation processes with minimal intervention from outside parties. This Plan is designed to provide guidance concerning reclamation and revegetation activities for Rocky Mountain Natural Gas, LLC (RMNG), doing business as Black Hills Energy (BHE), land managers, to be implemented when ground disturbing activities cease. The area to be reclaimed and revegetated shall be kept as weed free as practicable of all noxious weed species. Weed control measures shall be conducted in compliance with the Colorado Noxious Weed Act (C.R.S. 35-5.5-101.et.seq), Garfield and Eagle Counties Noxious Weed Management Plan, and RMNG Cottonwood Pass 6 -Inch Pipeline project - specific plan. Stormwater mitigation will be in compliance with the Colorado Department of Public Health and Environment (CDPHE) Water Quality Division General Permit Series COR -400000. Procedures identified in this plan apply only to the defined area of the Cottonwood Pass 6 - Inch Pipeline ROW. Personnel working on this project should be familiar with the revegetation plan and its contents prior to preliminary construction activities. 1 MIM Black Hills Energy 2.0 Site Characterization The community of Carbondale is the nearest population center, approximately 2.5 miles east of the pipeline ROW. The location ranges between approximately 6,000 to 8,600 feet in elevation and receives around 16-18 inches of rain per year. The frost free period ranges from 75 to 105 days, creating a growing season of approximately three months.

Reclamation activity will be in compliance with CDPHE COR400000 General Stormwater permit, Colorado Parks and Wildlife (CPW) stipulations, as well as the Garfield and Eagle Counties Revegetation Guide. The Cottonwood Pass Pipeline Project will be disturbing approximately 127.3 acres and will require revegetation. Approximately 36 acres will be disturbed in Garfield County and approximately 91 acres will be disturbed in Eagle County. Any bore sites will be re- contoured, seed bed prepped and seeded with appropriate seed mix and mulched. 5 filiff: MadtiMsEnow Wetland Crossing: RMNG will attempt to bore all wetland crossing when possible. Should boring operations fail, management of soils, mobilization of equipment and other precautions are discussed in the Stormwater Management Plan (SWMP). All soils within the wetland boundary will be separated by a physical barrier and replaced in the reverse of the order removed. Typically, the physical barrier will be created utilizing certified weed free straw. All stream channels will be restored to approximate original contour. 3.1 Stage One — Clean Up Once pipeline construction has been completed and topsoil has been redistributed across the ROW disturbance, all materials such as temporary erosion and sediment control measures, that are no longer necessary for sediment control, and other debris will be removed and disposed of properly. This includes any trash left behind on location such as pipe fittings, used lumber or miscellaneous items that have been discarded. Temporary fencing (as applicable) installed during construction will be removed. Existing fence lines or historic fence lines within the designated area of the ROW will be repaired, replaced, or removed as agreed upon by RIVING. 3.2 Stage Two — Soil/Seedbed Preparation The ROW shall be contoured to emulate the surrounding lands topography and pre-existing conditions. The soil used to contour the landscape will be applied in the order it was removed (i.e. first off, last on). This practice will ensure that the soil is applied to the appropriate horizon from which it was initially taken from. Salvaged topsoil will be distributed across the entire disturbed area at a depth of 6-12 inches when possible. Depending upon terrain, the seedbed preparation will consist of scarifying, tilling or harrowing the topsoil to a depth of three 3-4 inches. On side hills, where harrowing is not feasible, surface roughening can be obtaining using the bucket of a track hoe. This will occur just prior to seeding. In areas where the ground is saturated, seedbed preparation may be limited to surface roughening with the track hoe bucket as the operator backs out of the delineated wetlands area. 3.3 Stage Three — Seeding 3.3.1 Drill Seeding If topography allows, the ROW will be seeded using a drill seeder. Drill seeding will be performed at a depth of 0.5 inches, and the seed will be covered with soil and lightly compacted to ensure good seed -to -soil contact. Seed will be applied using a rangeland seed drill with a seed release and agitation mechanism sufficient to allow seeds of various size and density to be planted at the proper seeding depth. The seed mix for this reclamation project will be an approved Seed Mix by the Garfield County Vegetation Manager (Appendix B). Certified weed free straw will be applied at a rate 2,000 lbs/acre and will be crimped in placed. A Plantago -based tackifier, or similar product, may be applied at a rate of 1501bs/acre following drill seeding. 6 filig. Black rr 3.3.2 Broadcast Seeding Broadcast seeding will be implemented in areas where a drill seeder cannot safely and effectively maneuver. Broadcast seeding can be implemented by hand or by means of a mechanical device. Broadcast seeding provides a randomly dispersed plant community. Seeding rate when broadcasting will be double the drill seed rate. Once seeding is complete, seed will be raked in to ensure good seed -to -soil contact. Wetlands Crossings (If Necessary): All delineated wetland areas will be broadcast seeded. The wetland seed mix can be found in Appendix B. 3.3.3 Hydroseeding Hydroseeding, if implemented, will be applied at double the drill seed rate per acre. Hydroseeding will be applied prior to the application of hydromulch, to ensure greater seed -to -soil contact. Hydromulch may be applied at a rate of 3,000 lbs/acre and contain a guar gum tackifier. 3.3.4 Straw Mulch Straw mulch will be applied at 2000 lbs/acre and crimped in to ensure stabilization of mulch and soil. Straw mulch lowers surface soil temperatures by shading and increase infiltration rates by providing pores into the soils. Wetlands Crossing (If Necessary): Mulch will not be applied on wetland crossings. Ideally, planting will occur in the fall before the first snow of the season. Early -October is optimal, however, is not always feasible. If possible, planting should occur in conjunction with a predicted precipitation event. By positioning the seed below the snowfall or rain, the seed will receive good contact with the soil and utilize the benefits of the precipitation. Spring planting can be conducted after the frost line is gone from the soil. During all final reclamation, seeding within county ROW will be conducted with the approved Seed Mix associated with this project. Applicable landowner seed mix will be used on the ROW that crosses private lands. 4.0 Stormwater Mitigation 4.1 Best Management Practices (BMPs) To avoid erosion of topsoil and seed transport from storm events, Best Management Practices (BMPs) will be installed where applicable on the ROW. Surface roughening will reduce stormwater impact and capture and retain precipitation. Surface roughening is an erosion control practice often used in conjunction with grading and reclamation. Slopes that are not fine graded and left in a roughened condition also reduces erosion. Soil roughening reduces runoff velocity, increases infiltration, reduces erosion, traps sediment, and prepares the soil for seeding and planting giving the seed an opportunity to germinate and establish. Used as a temporary or permanent BMP, surface roughening may take many different forms including, but not limited to, ripping, pocking 7 MIN Black Mils Energy and tracking. For details on erosion and sediment control please refer to the Stormwater Management Plan. 5.0 Reclamation Monitoring Monitoring of the revegetation progress is vital to ensure that proper procedures are implemented on the location. Monitoring will allow for early response to potential problems encountered during the reclamation process. Identifying challenges to the reclamation goals at an early stage allows for adequate time to formulate a response to the situation. By identifying potential complications early in the process, the future costs associated with rehabilitation will be minimized for the operator. If the treatments do not show the desired outcome, additional actions will be taken to reach reclamation goals. After the source of the problem is identified, careful attention will be paid to the design and timing of the supplemental treatment. If treatments such as seeding are not carried out at the proper times, the treatments may not be effective and the operator will see increased rehabilitation costs. Monitoring activities will consider several parameters, including the condition of implemented BMPs, growth state and success rate of areas seeded, presence and location of noxious weeds, and other possible sources of reclamation failure. Photo documentation is required for all the above parameters for high-quality progress tracking. After the initial application of reclamation amendment, and when CDPHE revegetation requirements of 70 percent pre -disturbance levels have been met, monitoring will be at the discretion of RMNG. 5.1 Noxious Weeds In accordance with the Garfield County Noxious Weed Management Plan, noxious weed species will be treated before construction activities begin. Weeds identified on the ROW during and after construction will be treated as applicable to each species identified. Typically, treatment will occur three times a year. Weed species present on the ROW will be tracked during reclamation monitoring and reported to RMNG. All equipment used on this revegetation project will be cleaned and inspected prior to entering location to ensure no noxious weed seeds are transported onto the site. For details of weed management refer to the Cottonwood Pass Pipeline Project Weed Management Plan. 8 MIN Black Hills Energy 5.0 References Colorado Department of Public Health and Environment's (CDPHE) Stormwater Discharges Associated with Construction Activity Permit No: COR -030000.

Phone: 970-945-2568 Fax: 970-947-0012 APPENDIX C Reclamation Standards (Adopted May 7, 2001) Site stability A. The reclaimed area shall be stable and exhibit none of the following characteristics: 1. Large rills or gullies. 2. Perceptible soil movement or head cutting in drainages. 3. Slope instability on or adjacent to the reclaimed area. B. Slopes shall be stabilized using appropriate reshaping and earthwork measures, including proper placement of soils and other materials. II. Soil Management Topsoil management shall be salvaged from areas to be disturbed and managed for later use in reclamation. III. Erosion Prevention The surface area disturbed at any one time during the development of a project shall be kept to the minimum necessary and the disturbed areas reclaimed within ninety days to prevent unnecessary or undue degradation resulting from erosion. A. The soil surface must be stable and have adequate surface roughness to reduce run-off, capture rainfall and snow melt, and allow for revegetation. B. Application of certified noxious weed free mulch or erosion netting may be necessary to reduce soil movement, retain soil moisture, and promote revegetation. C. Soil conservation measures, including surface manipulation, reduction in slope angle, revegetation, and water management techniques, shall be used. D. Sediment retention structures or devices shall be located as close to the source of the sediment generating activities as possible to increase their effectiveness and reduce environmental impacts. V. Revegetation When the final landform is achieved, the surface shall be stabilized by vegetation or other means to reduce further soil erosion from wind or water, provide forage and cover, and reduce visual impacts. Specific criteria for evaluating revegetation success must be site-specific and included as a part of the reclamation plan. A. Vegetation production, species diversity, and cover, shall support the post -disturbance land use. Areas where the post -disturbance land use does not include lawns, gardens, and flower beds; shall approximate the surrounding undisturbed area or be revegetated to a desired plant community with a composition of species and plant cover typical to that site. B. The vegetation shall stabilize the site and support the planned post -disturbance land use, provide natural plant community succession and development, and be capable of renewing itself. This shall be demonstrated by: 4 1. Using certified noxious weed free seed. 2. Successful onsite establishment of the species included in the planting mixture and/or other desirable species. 3. Evidence of vegetation reproduction, either spreading by rhizomatous species or seed reproduction. 4. Evidence of overall site stability and sustainability. C. The revegetation plan shall provide for the greatest probability of success in plant establishment and vegetation development by considering environmental factors such as seasonal patterns of precipitation, temperature and wind; soil texture and fertility; slope stability; and direction of slope faces. D. To insure the establishment of a diverse and long-lasting vegetative cover, the permittee shall employ appropriate techniques of site preparation and protection species diversity should be selected for long-term land uses and to provide for a reduction in visual contrast. E. Where revegetation is to be used, a diversity of vegetation species shall be used to establish a resilient, self-perpetuating ecosystem capable of supporting the post - disturbance land use. Species planted shall include those that will provide for quick soil stabilization, provide litter and nutrients for soil building and are self -renewing. F. Integrated Weed Management (IWM) methods shall be employed for all noxious weed species on the Garfield County List. Weed management methods shall be used whenever the inhabitation of the reclaimed area by noxious weeds threaten nearby areas. G. Where revegetation is impractical or inconsistent with the surrounding undisturbed areas, other forms of surface stabilization shall be used.

SWMP Revisions 1.0 INTRODUCTION This Stormwater Management Plan (SWMP) has been created to comply with the Colorado Department of Public Health and Environment's (CDPHE) General Permit COR -030000 and applicable U.S. Environmental Protection Agency (USEPA) National Pollutant Discharge Elimination System (NPDES) stormwater regulations. This SWMP addresses construction activities associated with the construction of a Pipeline Right -of -Way (ROW) and materials staging yard for the construction subcontractor(s) working on the Pipeline ROW. This SWMP is intended to be periodically updated as needed to address planned developments, new disturbances, and other changes needed to manage stormwater and protect surface water quality. This SWMP contains general stormwater management practices, as well as site specific information related to specific construction activities. Site specific information (i.e. Phased Best Management Practices (BMPs) implementation, potential pollution sources, final stabilization measures, etc.) can be found throughout the text of this document. 1.1 Stormwater Runoff Permitting Requirements The Federal Clean Water Act [Section 402(p)] requires that discharges of pollutants to waters of the United States from any point source be regulated by NPDES permits. In compliance with the Colorado Water Quality Act (25-8-101 et seg., CRS, 1973 as amended) and the Federal Water Pollution Control Act, as amended (33 U.S.C. 1251 et seq.; the "Act"), this SWMP meets the requirements of the CDPS General Permit- stormwater discharges associated with construction activity Permit Number COR -030000, and the new COR -400000 permit. Stormwater construction permits are required for oil and gas activities that disturb one (1) or more acres during the life of the project, or are part of a larger common plan of development. Rocky Mountain Natural Gas, LLC (RMNG), doing business as Black Hills Energy (BHE), will oversee all aspects of this project. Contractor(s) will conduct the actual construction and grading with all work supervised by RMNG and all decisions made by RMNG.

Approximately 36 acres will be disturbed in Garfield County and approximately 91 acres will be disturbed in Eagle County. The project has been broken out into multiple phases. Each phase of the ROW will be seeded and mulched upon construction completion. Temporary Use Areas (TUAs) will be reclaimed to original contours. The main objective of this project is to construct a pipeline ROW for natural gas transportation. Activities associated with construction of the project that may affect stormwater include; clearing and grading, access road modifications, vehicle operation, maintenance and fueling; coating pipe joints, and possible herbicide application to control noxious weeds. The pipeline ROW for the proposed site is on state, county, and private land. 2.3.1 Clearing/Grubbing/ and Grading The ROW will be grubbed as applicable along the proposed route. Prior to earth disturbing activities, straw bales or straw wattles will be placed along the edge of disturbance where grades are greater than 3:1. The construction site will be cleared and grubbed as applicable. Topsoil and/or other materials will be salvaged or stockpiled as necessary. All stock piles will have stormwater Best Management Practices (BMPs) implemented to reduce sediment transport and erosion of topsoil as needed. Sediment traps, rock check dams, and diversion ditches may be implemented where applicable. Check dams may be utilized in ditches to dissipate water flow velocity. 2.3.2 Trenching/Backfilling Once clearing/grubbing and grading are completed, trenching will commence. BMPs installed prior to construction may continue to be used. Erosion and sediment controls installed that are no longer necessary will promptly be removed. Open trench will be backfilled at the end of each work day. When feasible, trench spoils will be stored on the up gradient side of the trench. Spoil stock piles that are unable to be stored on the up -gradient side of the trench will have erosion and sediment controls installed to mitigate sediment transport. Soils will be placed in the trench in reverse order of removal. Last soil to be excavated will be first to be backfilled, leaving the topsoil as the last stockpile to be spread evenly across the ROW. Any excavated materials not used for backfill will be disposed of properly. 2.3.3 Final Reclamation Reclamation, where applicable, will occur after the pipeline is installed and backfill activities are completed. Temporary BMPs no longer necessary may be removed and permanent BMPs will be installed. Erosion control blankets or spray on tackifier may be utilized. Seeding will occur in accordance with Garfield County Revegetation requirements. Site specific reclamation details are provided in the reclamation plan. Cottonwood Pass Pipeline Stormwater Management Plan 6 Each activity in the project will be under routine inspection until final stabilization has occurred. Construction is expected to begin in April of 2019. An inactivation notice will be filed for the project once all of the construction activities have been completed and all areas have reached final stabilization as described in section 5.3. Cottonwood Pass Pipeline Stormwater Management Plan 7 3.0 POTENTIAL POLLUTION SOURCES Potential pollution sources associated with the construction of the natural gas pipeline ROW project include: All Phases: • Sediment resulting from erosion of soil stockpiles and other areas cleared of vegetation; • Vehicle tracking on paved roads; • Leakage of fuels and lubricants from equipment and spills from fueling; • Trash and debris from clearing activities, construction materials, and workers; and • Sanitary sewage associated with portable toilets. The most common source of pollution from construction is sediment, which can be transported off the work site with stormwater runoff and ultimately impact the water quality of receiving waters. Clearing, grading, and otherwise altering previously undisturbed land has the potential to increase the rate of soil erosion compared to pre -disturbance rates. For locations of potential pollution sources, refer to the Site Map in Appendix A. There are currently no anticipated concrete or asphalt batch plants associated with this project. All BMPs implemented throughout the project are intended to mitigate for the release of sediment and all other potential pollution sources described above. Refer to Appendix A for site specific locations of potential pollution sources and locations of BMPs implemented to mitigate for the potential release of the respective potential pollutants. RMNG spill prevention and response policies must be followed and include the following: • Notification procedures to be used in the event of a material release or accident. At a minimum, the field supervisor should be notified. Depending on the nature of the spill and the material involved, RIVING staff, the CDPHE, downstream water users, or other agencies may need to be notified. The Water Quality Control Division (WQCD) toll-free 24-hour environmental emergency spill reporting line is 1-877-518-5608. • Provisions for absorbents will be made available for use in fuel areas, and ROW access points. A spill prevention, control, and countermeasure (SPCC) plan will be developed for any above ground containers that will store more than 1,320 U.S. gallons of hydrocarbons on site. Refer to the SPCC plan for additional information on spill prevention and response. Cottonwood Pass Pipeline Stormwater Management Plan 8 4.0 DESCRIPTION OF SOIL CONTROL MEASURES The objective of erosion and sediment controls is to minimize the release of sediment and other potential pollutants by stormwater runoff. This can be accomplished through the use of structural and/or nonstructural controls. This section describes erosion and sediment controls to be used during the pipeline construction to minimize possible pollutant impacts to stormwater runoff. Refer to Appendix D (Installation Details) for implementation details of soil control measures. Refer to Appendix A (Site Map) for locations of soil control measures. 4.1 Structural Practices for Erosion and Sediment Control Structural practices implemented to provide erosion and sediment control can include temporary and permanent BMPs. Temporary structural BMPs include, but are not limited to; straw bale barriers/check dams, temporary water bars and straw fiber rolls/wattles. When applicable, temporary BMPs will be implemented during construction and interim reclamation phases. All temporary BMPs will be removed upon final stabilization. Permanent structural BMPs include, but are not limited to; earthen berms, drainage dips, bar ditches, diversion ditches, sediment basins, culvert inlet/outlet protection, and rock check dams. 4.1.1 Rock Check Dams Rock check dams may be installed in areas of concentrated flow. The purpose of a check dam is to reduce the velocity of water, while allowing the clean water to continue migrating. Some sediment will accumulate behind the check dam. Sediment should be removed from behind the check dams when it has accumulated to one-half of the original height of the dam and properly disposed of. Check dams will be inspected for erosion along the edges of the check dams and repaired immediately, as required. 4.1.2 Straw Wattles Straw wattles are intended to capture and keep sediment on a disturbed slope. Straw wattles are useful to temporarily stabilize slopes by reducing soil creep and sheet and rill erosion until permanent vegetation can be established. Straw wattles will last an average of one (1) to two (2) years. The slope needs to be prepared before the wattles are placed. Small trenches are created across the slope on the horizontal contour. The trench should be deep enough to accommodate half the thickness of the wattle. The trenches need to be 10 to 25 feet apart. The wattles need to be installed perpendicular to water movement, parallel to the slope contour. The wattles need to fit snugly against the soil. No gaps should be between the soil and wattle. There should only be one (1) to two (2) inches of stake exposed above the wattle. The stakes should be installed every four (4) feet. 4.1.3 Roadside Bar Ditch Roadside bar ditches can be a temporary or permanent structural BMP installed to direct runoff or run-on stormwater away from construction activity. Ditches direct water into sediment basins or other BMP structures designed to capture sediment while allowing clean water to move through. Cottonwood Pass Pipeline Stormwater Management Plan 9 4.1.4 Culvert Inlet/Outlet Protection Inlets and outlets of culverts will be protected to prevent sediment build up within the culvert, thus maintaining culvert functionality. Temporary protection during construction can be implemented by installing straw bales or straw wattles around the inlet/outlet. For permanent protection, inlets/outlets can be protected via rock armoring. Sediment accumulated at the inlet/outlet shall be removed as needed to ensure that there will be no blockage of the culvert. 4.1.5 Water Bars Water bars can be a temporary or permanent structural BMP installed to direct stormwater runoff or run-on away from construction activities. Water bars slow the velocity of the water, and direct water into a sediment basin, or other associated BMP structure designed to capture sediment while allowing clean water to move through. 4.2 Non -Structural Practices for Erosion and Sediment Control Non-structural practices implemented for erosion and sediment control will consist of permanent BMPs that will be utilized during all project phases from construction to interim reclamation, and ultimately to final stabilization. Non-structural controls typically include, but are not limited to; vegetative buffers, mulching, seeding of disturbed areas, erosion control blankets, and surface roughening, and administrative management. 4.2.1 Seeding of Disturbed Areas Seeding of disturbed areas will be implemented as a measure taken to achieve final stabilization. Upon construction completion, all disturbed areas to undergo reclamation shall be seeded. As a disturbed area is seeded, it will remain in the interim reclamation phase until the site has reached a vegetative cover of 70% of pre -disturbance conditions. At this point, the site will be at the final stabilization phase. The main objective of drill seeding is to place the seed in the soil at the depth most favorable for seed germination. Topography will determine if seed will be applied via a drill seeder, hand broadcast or hydroseeding. Hand broadcasting is commonly used in areas too small for large equipment or if the terrain is too steep for equipment to work safely. Broadcast seeding throws the seeds randomly on the soil surface. This allows for a more mosaic plant population, but must be applied at twice the drill seed rate for successful germination. Once seed has been broadcast, raking or chaining the area will ensure seed to soil contact. Refer to Appendix E for the Project seed mixes and associated application rates. 4.2.2 Mulching Mulching is a non-structural BMP implemented to aid in seed establishment. After a disturbed area has been seeded, certified weed free straw mulch will be applied at two tons per acre. Where accessible, the mulch will be crimped into the ground to provide additional soil stabilization. A tackifier may be applied once the ROW has been mulched to ensure mulch is not blown away. 4.2.3 Surface Roughening Surface roughening is an erosion control practice often used in conjunction with grading. Surface roughening involves increasing the relief of a bare soil surface with horizontal grooves by either stair -stepping (running parallel to the contour of the land) or using construction equipment to track the surface. Slopes that are not fine graded and left in a roughened condition also reduces erosion. Soil roughening reduces runoff velocity, increases infiltration, reduces erosion, traps sediment, Cottonwood Pass Pipeline Stormwater Management Plan 10 and prepares the soil for seeding and planting; giving the seed an opportunity to germinate and establish. Used as a temporary or permanent BMP, surface roughening may take many different forms including, but not limited to, ripping, pocking and tracking. 4.2.4 Erosion Control Blankets Erosion Control Blankets (ECBs) are structural BMPs installed to eliminate rain drop impact on soil particles. Erosion control blankets are permanent, non-structural BMPs installed on steep slopes to provide soil stabilization and to keep seed in place. Erosion control blankets are a geotextile biodegradable material that is implemented during the interim reclamation phase. Cottonwood Pass Pipeline Stormwater Management Plan 11 5.0 PHASED BMP IMPLEMENTATION The Cottonwood Pass Pipeline project will consist of a construction phase, an interim reclamation phase, and a final stabilization phase. The following sections outline specifications of each phase. 5.1 Construction The construction stages of the project will consist of clearing, trenching and backfilling. Appropriate BMPs will be installed for this stage of the construction. The following outlines the necessary steps of the construction stage: All Phases: • Vegetation Clearing: Vegetation will be removed and place around edge of disturbed area on the down gradient side of the fill slope, as applicable. • Asphalt clearing: Asphalt will be removed the width of the necessary trench and stockpiled wherever space is available. Trench will be back filled every day. • Straw bale barriers will be installed as a temporary BMP prior to construction. • Straw wattles will be installed as a temporary BMP prior to construction. • Street sweeping will occur as applicable during construction within drive lane. Construction Start Date: Inspector: 5.2 Interim Reclamation Interim reclamation will be the phase of the project between construction and final stabilization. The project will enter into interim reclamation when construction is completed, disturbed areas have been seeded, and permanent BMPs have been installed. Temporary BMPs that were implemented during the construction phase may continue to be maintained during interim reclamation. The project will remain in interim reclamation until disturbed areas have been reclaimed to 70 percent of pre -disturbance vegetation or otherwise permanently stabilized (i.e. graveled). Please refer to the reclamation plan for more detail. The following steps will be taken to reach interim reclamation: All Phases: • Disturbed areas will be seeded to prevent sediment transport, and enhance soil integrity for reclamation. o Area will be drill seeded where terrain allows. Broadcast or hydroseeding will be implemented for areas not suitable for a drill seeder to access. • Temporary BMPs such as straw bale barriers and wattles will be removed if no longer a viable BMP. o All wooden stakes used to secure wattles and straw bales and other waste associated with construction of the site will be disposed of properly. • Slopes steeper than 2:1 will be hydroseeded and mulched or stabilized with Erosion Control Blankets (ECBs). Cottonwood Pass Pipeline Stormwater Management Plan 12 • All revegetation efforts will comply with the Cottonwood Pass Pipeline Re -vegetation Plan. • Temporary fencing installed during construction will be removed. Existing fence lines or historic fence lines within the designated area of the construction site will be repaired, replaced, or removed as agreed to by RIVING. • Areas not seeded will be graveled or otherwise permanently stabilized (i.e. paved). Interim Date: Inspector: 5.3 Final Stabilization Areas which have been disturbed are considered to be stabilized when a uniform vegetative cover with a density of 70 percent of the pre -disturbance levels has been established, or when an equivalent permanent, physical erosion reduction method is in place. Disturbed areas will remain in interim reclamation status until final stabilization is achieved. Stormwater compliance inspections will be performed at required intervals until final stabilization is reached. Temporary BMPs will be removed and disposed of properly. When final stabilization is achieved and all temporary control measures have been removed RIVING will apply for an Inactivation Notice to terminate the Cottonwood Pass Pipeline Stormwater Permit and Stormwater Management Plan. Final Stabilization Date: Inspector: Cottonwood Pass Pipeline Stormwater Management Plan 13 6.0 MATERIALS HANDLING AND SPILL PREVENTION 6.1 Waste Management and Disposal The construction activities mentioned in this SWMP will generate various other waste materials during the course of construction. These wastes typically include, but are not limited to: • Trees and shrubs from clearing operations; • Trash and debris from construction materials and workers; • Sanitary sewage from temporary sanitary waste facilities; • Sediment in areas that vegetation establishment is lacking; • Milled asphalt; and • Petroleum products from heavy equipment. Each of these wastes will be managed so as to not contribute to stormwater pollution. 6.2 Fuels and Materials Management Petroleum Products Petroleum products which may be present at the construction site include, but are not limited to: gasoline, diesel fuel, lubricant oils, hydraulic oils, used oils, and solvents. Gasoline and diesel fuel will be stored in portable storage tanks with secondary containment. Lubricant, hydraulic, and miscellaneous oils and solvents will be stored in containers up to 55 -gallons in volume. All storage containers must be compatible with proposed contents. Storage containers will be labeled with contents and placed in a secondary containment. Pollutants from petroleum products used during construction activities adhere easily to soil particles and other surfaces. In case of a spill or leak, soils contaminated with petroleum products will be contained and removed to a proper disposal site. Proposed soil erosion and sediment control practices can aid in retention of spills or leaks. Use of secondary containment and drip pans will reduce the likelihood of spills or leaks contacting the ground. Proposed maintenance and safe storage practices will reduce the chance of petroleum products contaminating the site. Oily wastes such as crankcase oil, cans, rags, and paper containing oils will be placed in proper receptacles and disposed of or recycled. An additional source of petroleum contamination is leaks from equipment and vehicles. Routine daily inspections will be conducted to identify leaks and initiate corrective actions, if needed. The following guidelines for storing petroleum products will be applied: • All product containers will be clearly and properly labeled; • Emergency spill response procedures will be available on-site. Persons trained in handling spills will be on call at all times; • Spill cleanup and containment materials (e.g. absorbent, shovels, etc...) will be readily available. Spills will be immediately cleaned up and contaminated materials will be properly stored on site until they can be disposed of in accordance with applicable regulations; • Containers will be regularly monitored for leaks and repaired or replaced as necessary. Cottonwood Pass Pipeline Stormwater Management Plan 14 Materials Management The construction contractor will maintain a staging area for equipment and materials storage on site. These areas will be maintained with good housekeeping and will be inspected on a regular basis for spills, leaks, and potential contamination. 6.3 Construction Site Housekeeping Housekeeping, during BMP repair or maintenance, will consist of neat and orderly storage of materials and containerized fluids. Wastes will be temporarily stored in sealed containers and regularly collected and disposed of at appropriate off-site facilities. In the event that a spill occurs, prompt cleanup is required to minimize any commingling of waste materials with stormwater runoff. Cottonwood Pass Pipeline Stormwater Management Plan 15 7.0 DEDICATED CONCRETE OR ASPHALT BATCH PLANTS No concrete or asphalt batch plants are anticipated for this project. Cottonwood Pass Pipeline Stormwater Management Plan 16 8.0 VEHICLE TRACKING CONTROL As the project progresses, access to the ROW will be clearly marked and track pads or other mud and sediment removal devises will be implemented. Refer to the site map and installation details (Appendix A, D respectively). Cottonwood Pass Pipeline Stormwater Management Plan 17 9.0 INSPECTION AND MAINTENANCE PROCEDURES To meet requirements of the General Permit, inspection and maintenance of erosion and sediment controls must occur during the project. Continued inspection and maintenance is required for specific structures after construction is completed. The inspection program will include the following: 1. A certified person familiar with the SWMP and control measures will conduct the inspections. 2. Inspections will cover the following items within construction site: • Disturbed areas without stabilization; • All structural and non-structural BMPs (temporary and permanent); • Material storage areas; • Surface water diversions; • Down gradient areas; • New access roads; • Site vehicle entrance/exit locations. 3. Inspections will occur at least once every week (during construction), and after a significant precipitation event or snow melt event that causes potential for erosion. Once all measures have been taken to reach interim reclamation, inspections shall occur at least once every 30 calendar days. 4. A log of inspections will be maintained. 5. Water quality will be visually assessed for all receiving streams and discharge areas during each inspection. 6. Disturbed areas and material storage areas that are exposed to precipitation will be inspected for evidence of pollutants entering nearby drainages. 7. Roads used for vehicle access will be inspected for evidence of off-site sediment transport. 8. Following each inspection, the SWMP will be modified as necessary to include additional controls designed to correct identified problems. Necessary revisions to the SWMP will be made within 72 hours of the inspection. 9. An inspection report summarizing the scope of the inspection, the name of the person conducting the inspection, the date of the inspection, and observations relating to proper implementation will be prepared. Inspection reports will be retained for at least three years from the date that the site is finally stabilized. 10. Actions taken to modify any stormwater control measure will be recorded and maintained with the SWMP. 11. If no deficiencies are found during the inspection, the report will contain certification that the site is in compliance with the SWMP. Maintenance Procedures Maintenance will include prompt repairs and/or adjustments to any erosion and sediment control structures that are deteriorating or found to be performing inadequately. BMP conditions and dates of BMP maintenance will be documented within the stormwater inspection checklists. Repairs are to be made as soon as possible and prior to the next anticipated storm event. Cottonwood Pass Pipeline Stormwater Management Plan 18 Inspection Forms Inspection forms shall be a part of this SWMP and will include information such as dates of maintenance/modifications of existing BMPs, installation of new BMPs, any site housekeeping requirements, and general comments. Refer to Appendix C for an example of the stormwater inspection document. Employee Training HRL inspectors are all certified stormwater inspectors. The respective inspectors receive training and continuing education with regards to stormwater and reclamation on a yearly basis. Initial stormwater training is conducted by Altitude Training, and continuing education classes are attended each year through the International Erosion Control Association and Altitude Training. A weekly meeting is conducted to ensure all inspectors apprised of changes to permits and regulations for applicable agencies. Environmental Training is provided to the operator upon request, usually pertaining to specific facility locations. This training provides an overview of stormwater management, spill response and waste management.

Appendix D BMP Installation Details Armored Rundown Description and Purpose: Armored rundowns are excavated channels or swales that are lined with grass, riprap or another protective material. Armored rundowns are intended to convey concentrated stormwater runoff down a gradient to a stable outlet while preventing erosion and sediment transport on or at the bottom of the slope. Riprap-lined channels also help to diffuse stormwater flows, and help prevent scouring in the channel. An armored rundown can be used as a temporary BMP during construction operations until final stabilization is installed, or utilized as a permanent BMP. Installation: • Armored rundown channels may exhibit V-shaped, parabolic or trapezoidal cross- sections. It is advised that all rundowns be lined with a protective material, fiber liner, or matting to prevent stormwater runoff from scouring under the BMP. • For grass -lined channels, a dense cover of hardy, erosion -resistant grass should be established as soon as possible following the installation of the rundown channel. Utilizing straw mulch, a protective liner or another tackifier will assist in the vegetation establishment. Side slopes should not exceed 3:1 in order to facilitate vegetation establishment and slope stabilization. • Riprap-lined channels are generally installed on steeper slopes than grass -lined channels. Before installing riprap, the channels require a filter fabric or protective liner to prevent scour under the riprap. The volume of stormwater flows will determine the best rock size for the rundown. Larger rock shall be used for larger stormwater volumes. Generally, side slopes should not exceed 2:1, and the riprap thickness should be 1.5 times the maximum stone diameter. The riprap should be installed in a dense, uniform, well - graded accumulation. Inspection and Maintenance: • In the construction phase, all BMPs will be inspected every 14 days or within 24 hours of a significant storm event. In the interim phase, BMPs will be inspected every 30 days. • Access to perform maintenance on the armored rundown should be provided. The rundown should be inspected for scouring or down cutting under the protective material, and repairs should be completed as soon as possible to prevent further scour and sediment loss from under the BMP. • Maintenance should focus on the function of the feature. If the rundown is lined with riprap, monitor the placement of the rocks to ensure they are functioning, and ensure the rock size installed is effective for the runoff volume. Any lost riprap shall be replaced. • Check embankments, spillways, and outlets for erosion, piping and settlement. Clogged or damaged spillways and/or embankments should be restored to design specifications. • Temporary conveyances shall be completely removed as soon as the surrounding drainage area has been stabilized, or at the completion of construction. Berms Description and Purpose: Earthen berms are used to intercept and divert runoff to a desired location such as a sediment trap or a slope drain. Berms can be used in conjunction with a diversion channel to convey runoff or run-on. Berms are commonly used along the top edges of cuts and fills to protect the embankment. Berms also contain and divert water from disturbed areas in order to control storm water and sediment leaving the site. Berms to intercept and divert runoff should not be used where the drainage area exceeds 10 acres. Installation: Berms and diversions should be constructed of compacted soil and have uninterrupted positive grade to a stabilized area, such as a sediment trap. The minimum height of a berm should be 18 inches with side slopes of 2:1 or flatter and a minimum base of 4.5 feet. The diversion channel should be constructed to allow 6 inches of freeboard and be clear of debris that would compromise the function of the structure. The berm and diversions should have sufficient capacity to carry peak runoff expected form a 2 -year frequency storm. Maintenance: Inspection and maintenance should be provided periodically and after rain or snowfall events that cause significant runoff. Berms should be inspected for breaches, erosion, tunneling or by-passing the structure. Sediment buildup against the berm or in the channel should be removed if the sediment is impacting the function of the structure. Riprap or turf reinforcement can be used to limit erosion in the diversion channels if water velocities are causing erosion. CWPaC'i0 jARTN BERM Brush Barriers �.s Description and Purpose: Brush barriers are composed of brush, tree branches, or root mats usually obtained during the site clearing and grubbing phase. These barriers are usually used for sediment trapping, reducing offsite sediment transport, and velocity reduction and are usually located along the site perimeter or in areas where sheet flow occurs. Brush barriers should be used a supplemental BMP in conjunction with a structural BMP such as a straw bale barrier, wattles or a diversion ditch or berm. Installation: Barriers can be installed approximately 5 to 10 feet from the toe of the slope along the perimeter of the site allowing enough room for the structural BMP placement. Brush barriers should be installed along the contour or perpendicular to the flow direction. The height of the barrier should be tall enough allow for settling of material and utilize smaller brush to limit void spaces and conduits for water to compromise the structure. Maintenance: Brush barriers should be inspected regularly or after a significant rainfall event. Channels or void spaces caused by erosion should be repaired to increase the effectiveness of the structure. Accumulated sediment should be removed if the height of the sediment of the uphill side reaches one half the height of the barrier. Once the site has reached final stabilization, the barrier can be spread out or disposed of properly. Rock Check Dams Description and Purpose: Rock check dams are temporary dam structures placed across drainages or channels and are used to slow stormwater velocities and reduce erosive potentials. Check dams are constructed using gravel, rock, sandbags, straw bales or other reusable materials. When properly installed, check dams reduce the effective slope of a channel, and reduce the velocity of the flowing water. Check dams can also be used to catch sediment from the channel as stormwater moves through the structure. One -rock check dams are temporary dam structures that are one rock tall by several rocks long (illustrated in the photo). One -rock check dams also slow the velocities of passing stormwater, provide suitable areas for vegetation establishment, and reduce erosion potentials. The dams provide sediment retention, and bank stabilization for small drainages or channels. Installation: • Dams should be installed with careful placement of the construction material, as to not allow material to move down the channel. • The center of the dam should be at a lower elevation than the edges to allow water to flow away from the banks and over the center of the dam, preventing erosion at the edges. The typical rock size is one to six inches. The larger size is preferred. • The dam should be keyed into the ditch for additional stability, and to prevent water from scouring under the dam. • Check dams should be utilized in a series and spaced as necessary to reduce flow velocities down a channel • The maximum spacing between dams should be such that the toe of the upstream dam is at the same elevation as the release point of the downstream dam.(*see illustration) Inspection and Maintenance: • In the construction phase, all BMPs will be inspected every 14 days or within 24 hours of a significant storm event. In the interim phase, BMPs will be inspected every 30 days. • Large debris, trash and leaves should be removed from the dams during inspections. * • Ensure the center of the dam is always lower than the edges. • Ensure run-off is not scouring under or around the BMP. • If rocks or material need replaced, repairs should be made immediately. • The dam should be cleaned of sediment if accumulated sediment has reached a height of approximately one-half the original height of the dam. • Check dams may or may not need to be removed depending on the material of construction and site specific conditions. Dams shall only be removed after the contributing drainage area has been completely stabilized.

Ay ....--..7.;•:. - - _._.,_...r_ Description and Purpose: A concrete washout area is a pollution prevention BMP that provides an area for concrete trucks, mixers, and hoppers to be rinsed out after delivery without contaminating surrounding soil or surface water bodies. Concrete washout areas must be designated on all locations that generate concrete waste water liquid waste from onsite mixing or delivery. It is important that the washout location be installed away from natural drainages, wetlands, or other shallow groundwater areas to prevent the potential transport of pollutants. The installation of the concrete washout area should be complete prior to any concrete placement on the site. Installation: • The concrete washout area shall be located on a flat surface, and if possible, should be installed inside a flat subsurface pit. • The washout area needs to be planned to accommodate all washout liquids, and any rainfall that could potentially fall into the area, without exceeding half of the total original volume. It is recommended that larger sites use a washout area that is ten (10) feet wide by ten (10) feet long, with berms or straw bales stacked at least eighteen (18) inches tall. • If the washout area exceeds a volume greater than half of the original volume, it needs to be cleaned out before any additional inputs. • The berm surrounding the washout area can be made from excavated dirt or made from straw bales. • A plastic liner of at least ten (10) mil thickness should be installed, and staked down every two (2) feet to the earthen or straw bale berm. • The concrete washout area should be installed at least fifty (50) feet away from any open water bodies or natural drainages. • Signs should be placed at the entrance to the construction site, and at the concrete washout area. • A vehicle tracking pad, generally constructed of rock, should be installed in front of the concrete washout area, and if possible, sloped two percent (2%) towards the washout area. • The concrete washout area shall remain on site until all concrete for the project is placed. Inspection and Maintenance: • In the construction phase, all BMPs will be inspected every 14 days or within 24 hours of a significant storm event. • It is important to ensure significant storm events do not exceed the volume of the washout pit, and careful planning should go into determining the necessary size of the washout pit prior to installation. • Ensure the BMP is in effective operating condition. Repair or replace any issues identified as soon as possible to the discovery of the problem. • Inspect for holes or tears in the plastic liner, or slumping in the berm. Replace any stakes that are not in operating condition. • All concrete waste in the pit shall be removed from the job site in a water -tight container and disposed of properly. Culvert Inlet and Outlet Purpose and Description: Culvert pipe is typically constructed of concrete, steel, aluminum or plastic and are used to move water under a roadway or direct stream flow under a road or construction area. Cross -drains are utilized to transport upland runoff, which accumulates in ditches, to the down -gradient side of the road to reduce road erosion. Pipe diameter and inlet/outlet protection depends on the volume of water passing through the culvert and should be evaluated on a case-by-case basis. Installation: If possible, culverts should be designed for a minimum 25 -year frequency storm event and be covered by enough material as to not protrude above the access road. Cover material above metal or plastic culverts should be at least one foot for every one inch of pipe (e.g., 18' culvert = 18" of cover). The outlet should be able to allow debris to pass through. Whenever possible, align the center of the culvert with the center of the existing channel, following the grade of the channel. If excavation of the channel is necessary, minimal disturbance of the channel at the culvert outlet should be the primary consideration. Compaction of fill around the inlet and outlet of the culvert is recommended to reduce erosion and settling. Inlet and outlets should have armoring above the culvert and both sides to reduce erosion and sediment transport from the road surface. A single large pipe is preferable to multiple smaller culverts to minimize plugging, however multiple smaller culverts can be considered to maintain the natural flow spread across the channel. Culvert outflows should discharge at natural ground level and not cause damming or pooling or significantly increase the velocity of the water. Spacing of culverts is dependent on the road gradient, soil types and runoff characteristics and should be approached on a case-by- case basis. Culvert inlet and outlet protection can be accomplished with a base left open to aid in maintenance with rock armoring around the base. The preferred depth is 18 inches to 36 inches of coverage. Rock armoring should be installed to ensure that the bank does not back cut, scour or erode. The same method can be used at the culvert inflow to reduce water velocity. The inlet should have rock armoring placed around the culvert in a horse shoe, protecting the top and sides. A sediment trap will be installed at the inlet and outlet to allow water to pool, slowing water velocity and allow sediment to drop out prior to entering the culvert. The sediment trap will not have armoring in the bottom, this will allow for easy maintenance. Riprap should be selected based on the expected flow and extend several feet from either end of the culvert pipe. Riprap should also be placed around the pipe at either end to limit erosion from surface runoff. Maintenance: Maintenance of culverts includes ensuring good flow through the culvert, checking for signs of corrosion or joint separation and sediment buildup. The inlet and outlet should be inspected for signs of scour, degradation, debris, flow diversion and erosion around the culvert. Sediment build-up around the inlet and outlet should be removed if the build-up is negatively impacting the system (increased water velocities, pooling, back flow, etc.). Riprap should be replaced or reused once sediment has been removed. Diversion Ditch Description and Purpose: A diversion ditch is an excavated channel or swale that can be cut to capture run-on, divert flows around a disturbance area, and transport surface water to a desired location. Additionally, ditches can be used to intercept and divert runoff towards a stabilized watercourse or channel, or intercept runoff from hardened surfaces such as well pads or roads to help intercept sheet flows, and convey concentrated flows. Ditches may be constructed in combination with an earthen berm to increase the capacity of the ditch. Other soil stabilization structures may also be integrated into the diversion ditch to assist in sediment control and capture, such as check dams or erosion control blankets which also prevent scour and erosion in newly graded swales and ditches. A diversion ditch may be utilized as a temporary or permanent BMP structure, and can be transitioned into a roadside ditch or a drainage swale. Installation: • Diversion ditches should be constructed with rounded or flat bottoms to avoid flow concentration and scouring at the bottom of the channel. • During installation, positive drainage should be verified to ensure proper function. • If the diversion ditch is greater than thirty (30) feet, the outlet of the ditch will be constructed with erosion protection (riprap) to ensure outlet stability and to prevent erosive potential from concentrated flows. Riprap aprons are best suited for temporary use during construction. • Diversion ditches should not include loose fill. A well -constructed ditch will convey flows within the feature without erosion. Inspection and Maintenance: • In the construction phase, all BMPs will be inspected every 14 days or within 24 hours of a significant storm event. In the interim phase, BMPs will be inspected every 30 days. • Access to perform maintenance on the diversion ditch should be provided. • The ditch should be inspected for scouring or down cutting at the bottom of the channel, and repairs should be completed as soon as possible to prevent further scour and sediment loss from the BMP. Rock check dams, riprap, and erosion control materials can be installed to reduce flow velocities, capture sediment and prevent scour. • If the outlet is armored with riprap, monitor the placement of the rocks to ensure they are preventing erosion, and ensure the rock size installed is effective for the runoff volume. If riprap has been lost, it should be replaced. • All linings and soil stabilizers need to be inspected for damage. Periodic re -definition of the ditch may be required to restore function and ensure effective drainage. Check embankments, spillways, and outlets for erosion, piping and settlement. Clogged or damaged spillways and/or embankments should be restored to design specifications. • Temporary conveyances shall be completely removed as soon as the surrounding drainage area has been stabilized, or at the completion of construction. Drive -Over Berms Description and Purpose: Drive over berms should be implemented as applicable at a pad entrance to mitigate stormwater run-on and runoff. The purpose is to contain stormwater and other possible contaminants that may be on the location and allowing as little runoff as possible from entering and damaging the access road. Installation: Drive over berms should be installed such that both ends tie into the pad perimeter berm. Berms should allow for traffic to move across the barrier easily while still keeping the containment necessary for the location. Berm should be properly compacted. The height and width should blend in with the pad perimeter berm. Inspection and Maintenance: In construction phase BMPs will be inspected every 14 days or within 24 hours of a significant storm event. In interim phase BMPs will be inspected every 30 days. Inspect berm for washouts, and remove excess debris and sediment as applicable. Erosion Control Blankets (ECBs) Description and Purpose Erosion control blankets are made out of environmentally friendly, biodegradable material, and are installed on disturbed slopes that are requiring stability. Erosion control blankets, (ECBs), not only retain sediment resulting from sheet -flow runoff, but also provide increased water holding capacity to the slope, which ultimately increases the rate and establishment of desired vegetative cover. Erosion control blankets are not recommended for excessively steep slopes, sandy soils, or slopes that have many rocks on the surface. Installation General • Erosion control blankets should be installed on a smooth slope surface with minimal rock material, vegetation or other obstructions. Any obstructions which rise above the level of the soil and mulch must be removed. The top soil should have been previously applied and the area seeded. • The blankets need to be installed smoothly on the surface of the soil, loose enough to allow for vegetation establishment. The blankets are to be in complete contact with the soil to prevent any tenting under the BMP. • Start by laying the center blanket in the direction of the flow, at the centerline of the waterway if applicable. • The chosen ECB should be installed up and down the slope, and never applied along the slope contour. Roll the blankets from the top of the hill if possible, and staple the blanket down as it is being unrolled to avoid stretching the ECB. • The upslope and down slope ends of the blankets should be buried in a trench with ideal dimensions of 6"x6", and the trench be backfilled and compacted. The trench on the upslope end of the blanket should be placed beyond the crest of the slope to avoid undercutting. • Where one blanket ends and another begins, the edges must overlap each other by at least three (3) feet. Rolls laid next to each other should overlap by at least six (6) inches across the slope. Uphill layers always overlap the downhill layers. • Anchor pins or staples should be used to attach the ECB to the ground surface. Utilize manufacturer's instructions if available. o Staples should be "U" shaped, and 0.12 inches in diameter or greater. Longer staples may be needed for sandy soils. o For joining ends of rolls, use a double row of staggered staples approximately four (4) inches apart. Staple roll overlaps across the slope at twelve (12) inch intervals. o The outer edge of the ECB shall be stapled at twelve (12) inch intervals. Staples are then to be placed in columns down the ECB at three (3) foot intervals down and two (2) foot intervals across the ECB. o The bottom end of the ECB shall be stapled with a double row of staggered staples, placed twelve (12) inches apart. • J -hooks should be applied at approximately 15 foot intervals down the hill slope. A J - hook consists of folding the ECB back over itself to the uphill side by six (6) inches, and pinning it down using a double row of staggered staples spaced at six (6) inch intervals. J -hooks help to prevent undercutting, and keep the water on top of the ECB. Erosion Control Blankets/Mats There are many types of erosion control blankets and mats, and selection of the appropriate type shall be based on the specific type of application and site conditions. Selection(s) made by the Contractor must be approved by appropriate and designated administrative personnel. Biodegradable rolled erosion control products (RECPs) are typically composed of jute fibers, curled wood fibers, straw, coconut fiber, or a combination of these materials. For an RECP to be considered 100% biodegradable, the netting, sewing or adhesive system that holds the biodegradable mulch fibers together must also be biodegradable.

Inspection and Maintenance • In the construction phase, all BMPs will be inspected every 14 days or within 24 hours of a significant storm event. In the interim phase, BMPs will be inspected every 30 days. • Repair any unnecessary gaps or holes in the blankets. • Ensure the ECBs are not being undercut, and that the staples remain in place. • Inspect to make sure that there is uniform contact with the soil. Flumes Description and Purpose: A flume is a pipe conduit that intercepts and reroutes water from a stream or drainage area and diverts the surface water to a stable discharge point, transporting the surface water over an area of disturbance such as a pipeline trench, an unprotected slope, or other construction area. Flumes can be temporary or permanent BMP structures, and are utilized to prevent water from impeding a construction area, causing erosive activities and contaminating surface water bodies, and from preventing construction operations. Depending on the size of the drainage area or volume of water in the stream, multiple pipe conduits can be utilized to appropriately transport the surface water. The conduit is generally constructed of aluminum, steel or concrete, and should be designed to meet the site specific needs. The flume should be designed to divert the appropriate volume of water for the project, which can include spring and stormwater runoff events. It is important to take into consideration runoff, and potential discharge to the drainage or stream, and to plan construction times for low flow periods. A moderate slope is required to generate adequate stream velocity and transport the water through the conduit to the discharge area. Installation: • The flume pipe conduits need to be installed in the streambed or drainage and be aligned with the natural stream flow. • The conduit needs to be installed on top of sandbags placed at either end of the pipe to allow for the plastic to be appropriately installed. • A temporary diversion structure needs to be installed to divert water into the flume pipe. • Plastic sheeting needs to be installed at the inlet and outlet of the flume. The sheeting needs to have a minimum thickness of 6 mil and needs to extend to both sides of the stream channel. The plastic sheeting should overlap the flume conduit inlet and outlet by a minimum of four (4) feet, extend outward approximately twenty (20) feet, and cover enough area on either side of the flume to prevent seepage and scour on either end of the BMP. o The plastic is placed after the flume pipe conduit is installed. o Straw bales are placed on top of the plastic and act as wing walls to divert the surface water. o The plastic is folded over the straw bales, and is held in place by stacking sandbags on the plastic, placed on the stream side of the straw bales. Sandbags are also placed on top of the plastic at the base of the flume on the stream bed to ensure the plastic stays in place. o The plastic should be folded over both conduit ends, and is cut around the pipe. Plastic is then allowed to enter the flume inlet and prevent any seepage or scour. • Depending on slope percentage, a splash pad consisting of rock or other riprap materials can be installed at the outlet of the flume, which can help to prevent soil scour and down cutting from the water discharge. Inspection and Maintenance: • In the construction phase, all BMPs will be inspected every 14 days or within 24 hours of a significant storm event. In the interim phase, BMPs will be inspected every 30 days. • Access to perform maintenance on the flume should be provided. The flume should be inspected for scouring or down cutting under the protective material, and repairs should be completed as soon as possible to prevent further scour and sediment loss from under the BMP. • Check the diversion structure and plastic for tears and movement, and ensure the seepage and erosion prevention structures are in working order. • Remove all debris, and repair holes, gaps or scouring areas as required. • It is important to remove all built-up sediment from the inlet to prevent flow constriction and flooding around the flume. • Temporary conveyances shall be completely removed as soon as the surrounding drainage area has been stabilized, or at the completion of construction. o If the flume is temporary, remove the structure and redirect flow back to the original stream channel upon completion of work. Dry Crossing Description and Purpose: A dry crossing allows for equipment to be tracked over a stream or drainage area without damaging the stream or drainage area. Dry crossings can be temporary or a permanent BMP structures. Dry crossings are utilized when access back and forth over a stream or drainage area is necessary. Dry crossings prevent sedimentation from the construction area, causing contaminating of the surface water bodies. It is important to take into consideration runoff, and potential discharge to the drainage or stream, and to plan construction times for low flow periods. Installation: When a mat or similar material can span the width of a drainage or stream without impeding precautions should be taken to ensure no sediment is transferred from equipment to the drainage. • Once the first mat is placed, a layer of marifi or plastic sheeting should be laid to prevent sediment transfer through cracks in the mat. • A second mat should be placed on the marifi or plastic sheeting. • A line of sandbags should be placed on the edge of the mats to prevent sediment from falling off the side of the newly constructed "bridge". • The excess plastic should be folded up the sides of the two mats and placed on the sandbags. Another layer of sandbags should be placed on top of the excess plastic to lock the plastic in place. o It is necessary that the plastic sheeting continues up and over the sand bags, installed along the bridge perimeter. This allows for capture of sediment that has fallen off of equipment during the crossing. (Please see below illustration). STREAM A/ Sand Bags di MATTING OVERVIEW STREAM PLASTIC OR - MARIFI SANDBAGS MATTING MATTING CROSS SECTION Inspection and Maintenance: • In the construction phase, all BMPs will be inspected every 14 days or within 24 hours of a significant storm event. In the interim phase, BMPs will be inspected every 30 days. • Access to perform maintenance on the crossing should be provided. The crossing should be inspected for scouring or down cutting, and repairs should be completed as soon as possible to prevent further scour and sediment loss from under and around the BMP. • Inspect the spacing between your crossing and the water level, to ensure washout is not possible. • Check the plastic for tears and movement, and ensure sediment transfer is not entering the drainage or stream. • Remove all debris, and repair holes, gaps or scouring areas as required. • Temporary conveyances shall be completely removed as soon as the surrounding drainage area has been stabilized, or at the completion of construction. Gabions Description and Purpose: Gabions are rectangular, semi -flexible wire baskets that are filled with rock and stacked atop one another to form a gravity type wall. Gabions are used to slow the velocity of concentrated runoff or to stabilize slopes in areas where other solutions are not adequate to hold such runoff. These baskets are permeable to water and help in areas that soil may erode under the design flow conditions. Installation: Gabions come in several different design configurations. Gabions should be professionally designed and installed in accordance with manufacturer's standards and specifications. Expected storm and flood conditions should also be considered when purchasing a particular gabion. General specifications are listed below; • Clear and grade the area of vegetation and unsuitable soils; • Compact subgrade firmly to prevent slumping; • Place empty gabion baskets for each layer of baskets reasonably straight and conform to the specified line and grade. Empty gabion baskets should be fastened to the adjacent baskets along the top and vertical edges; • Unless indicated on the plans, the vertical joints between basket units of adjacent tiers or layers, along the length of the structure, should be staggered by at least one cell; • Before filling each gabion with rock, all kinks and folds in the wire mesh should be removed and all baskets should be properly aligned; • Fill gabion row or layer in stages so local deformations may be avoided; • Fill should not exceed more than 12 inches more than any adjacent cell; • Rock should completely fill gabion baskets so the lid will lay on the rock when it is secure. Lid should be joined to the sides, ends, and diaphragms in the same manner as specified for joining the vertical edges. Inspection and Maintenance: In construction phase BMPs will be inspected every 14 days or within 24 hours of a significant storm event. In interim phase BMPs will be inspected every 30 days. Check for signs of rusting, wear of baskets, undercutting, or instability. Repair damaged areas to restore designed effectiveness and to prevent damage or erosion of the slope or stream bank. Roadside Bar Ditch Description and Purpose: Roadside bar ditches should be implemented in areas of road disturbances. The purpose of roadside bar ditches is to help access roads stay accessible. Roadside bar ditches help create a natural stormwater pattern that should lead to a proper drainage. Properly controlling the flow of stormwater will help keep the road from washing out and help keep stagnant areas of water off of the roadways. Installation: Roadside bar ditches should be installed accordingly with the existing topography and desirable natural surroundings to avoid extreme grade modifications. Bar ditch should be adequately built to help contain flow of water to the discharge point. Bar ditch should be compacted to help mitigate erosion and sediment loss. Road should be sloped to help provide good drainage of water from the surface of the road into the bar ditch. Inspection and Maintenance: In construction phase BMPs will be inspected every 14 days or within 24 hours of a significant storm event. In interim phase BMPs will be inspected every 30 days. Maintenance should focus on the function of the feature. Roadside bar ditches should be maintained and kept established to keep water from being stagnant. Check for unincorporated drainages and fill and redefine bar ditch accordingly. Maintain road sloping and repair any problems as soon as possible.

The purpose of the trap is to impound diverted water, usually from diversion ditches, allowing heavy particles to settle out. It can also be used as temporary storage of run-on and run-off. Ideally, sediment traps are during earth disturbance activities and are located down gradient of activity. Sediment traps vary in shape but consist of an impoundment area to collect stormwater and rock spillway to decant clear water if desired. Installation: Greater surface area increases the trapping efficiently of a sediment trap. Sediment traps can vary in size and shape depending on site conditions and area of disturbance. A minimum ratio of 2L: 1W should be utilized if conditions allow. Embankment width should be 5 feet if allowable by site conditions. Soils forming the embankments and the interior of the sediment trap should be compacted to limit infiltration and erosion of the trap. Sediment Traps should discharge to stable, erosion resistant areas and not create offsite stormwater issues. A spillway will be constructed on the outflow side of the sediment trap and armored. Spillway length depends on the amount of acres being disturbed and is described in table 1. The spillway should utilize geotextile erosion control material over compacted backfill with angular rock armoring. Maintenance: Access to perform maintenance on the sediment trap should be provided. Sediment from the trap should be removed when the wet storage volume has been reduced by one half. A stake could be utilized to mark the sediment height at which maintenance should be performed. Maintenance should focus on the function of the feature. Check embankments, spillways, and outlets for erosion, piping and settlement. Clogged or damaged spillways and/or embankments should be restored to design specifications. Seeding Description and Purpose: Seeding is utilized to assist in the establishment of vegetative cover on disturbed areas. Vegetative cover is considered the most effective deterrent for surface erosion. Vegetative cover stabilizes the soil, reduces the amount of surface runoff during storm events by promoting infiltration, and assists in filtering out sediment from stormwater runoff. Temporary seeding should be utilized when the soil surface is disturbed and will remain inactive for an extended period (generally 30 days or longer). Temporary seeding is utilized for areas that will be in dormancy, or may not be ready for final stabilization. These areas include: top soil storage piles, temporary berms, or cut and fill slopes. Interim seeding is utilized for well pads that have completed the construction phase, and are reducing the effective disturbance size of the location to areas needed for production operations or for subsequent drilling operations only. Final seeding is implemented to permanently stabilize the entirety of the disturbance area after all construction and production operations are complete. There are a variety of methods than can be used to achieve the temporary, interim and permanent vegetative cover required. These seeding methods include: • Drill/Disc — preferred method; • Broadcast; • Hydraulic (with or without the addition of a tackifier); and • Hand (where applicable due to terrain and accessible distance). Hydraulic erosion control consists of applying a mixture of shredded wood, coconut and wood fiber, or a hydraulic matrix and a stabilizing emulsion or tackifier with hydroseeding equipment. Hydraulic erosion control temporarily protects exposed soils from erosion by raindrop impact or wind. Hydromulch quickly bonds to the soil, and can provide slope protection and essential seed - to -soil contact necessary for successful and rapid germination leading to desired vegetative establishment and cover. Installation: • If hand broadcasting the seed — the seed should be harrowed into the soil to promote proper seed to soil contact. • Temporary seeding should include annual, cereal crops such as oats, barley or sterile hybrids to establish vegetative cover and suitable grass species on areas not currently being utilized for construction or project work. Temporary seeding should occur as soon as possible following construction to promote soil stabilization and to reduce runoff and erosion potentials. • Interim/permanent seeding will utilize the seed mix designated for permanent seeding and vegetative cover. Land on a well site that is not being used for production but has been disturbed should be re-contoured, and applied with topsoil prior to the seeding and re -vegetation process. • Final/permanent seeding will be installed upon completion of all construction and operation activities in order to reach final stabilization for the site. • The permanent seed mix, rate, application method and supplemental materials will be determined by appropriated personnel or the BLM/Landowner as appropriate for the land ownership. • Permanent seeding is most effective when the seed is applied in the early fall, when the soil is warm, temperatures are moderate, weed competition is minimal, and growing conditions are optimal. Re -contouring, surface roughening, and topsoil replacement shall be completed prior to permanent seeding. • Drill/Disc seeding shall be installed along the contour of a slope's profile to prevent rill formation and runoff concentration. • Mulch is often applied immediately after the seeding process to protect the seeding area from precipitation or wind erosion. Mulch also increases infiltration and reduces runoff. Mulching with weed -free straw, hay, shredded wood mulch or other matrices should be evenly applied to disturbed soils, and secured by crimping, using tackifiers, or other measures. Inspection and Maintenance: • In the construction phase, all BMPs will be inspected every 14 days or within 24 hours of a significant storm event. In the interim phase, BMPs will be inspected every 30 days. • To maintain a viable seed bed, it is important to minimize any vehicle traffic or other forms of compaction in areas that are seeded. • Any areas that have experienced erosive activity or surface disturbance shall be re- contoured and seeded as soon as reasonably possible. • Areas that have been seeded but are not experiencing reasonable vegetation establishment after one growing season should be re -seeded, and considered for a soil amendment such as a form of mulch, fertilizer or other soil amendment. Straw Bale Barrier Description and Purpose: A straw bale barrier is a temporary best management practice (BMP) consisting of a row of entrenched and anchored straw bales installed on a level contour. Straw bale barriers are utilized to control sheet -flow stormwater runoff, and to capture sediment from being transported from a construction site or disturbance area. When appropriately placed on a level contour, a straw bale barrier intercepts and reduces the velocity of sheet -flow runoff, and causes temporary ponding. The temporary ponding provides conditions for sediment to settle out of the stormwater. Straw bale barriers also interrupt slope length and thereby reduce erosion by reducing the tendency of sheet flows to concentrate into rivulets, causing rills and gullies on disturbed, sloped soils. Straw bale barriers can be installed on features such as: toe slopes of erodible hillsides, as sediment traps at culvert/pipe outlets, along the perimeter of construction sites, down slope of exposed soil areas, around temporary stockpiles and spoil areas, parallel to a roadway to keep sediment off paved areas, or along streams and channels. As a linear erosion control measure, bales can be installed along the face of a slope to shorten slope length and intercept stormwater runoff They can also be installed at the top of slopes to divert runoff from a disturbance area, or as a form of check dam to interrupt stormwater runoff velocities (see the check dam installation detail). Installation and Implementation: • Straw bale barriers shall be installed prior to any land disturbing activities. • Straw bales should consist of certified weed free straw or hay. Local jurisdictions may require proof that bales are weed free. • Straw bales should be installed in a single row on a level contour. • The ends of the bales shall be tightly abutting one another. • All bales should be installed on their sides so that the twine or binding runs around the side of the bale rather than on the top and bottom. • All bales should be trenched into the ground to prevent water from scouring under the straw bales. The trench shall be excavated to a uniform depth of 4 inches. • Each bale is to be securely anchored with at least two stakes. • All excavated soil and trench waste shall be backfilled on the uphill side of the straw bale barrier. Materials • Straw Bale: Each bale should be a minimum of 14 inches wide, 18 inches in height, and 36 inches in length. Each bale should weigh a minimum of 50 pounds. • Bale Bindings: Bales shall be bound by steel wire, nylon or polypropylene string. Bailing wire shall be a minimum of 14-guage diameter, and Nylon or polypropylene string should be approximately 12-gauage in diameter. • Stakes: Wood stakes should be of a commercially quality lumber, free from decay, cracks or splits that would weaken the integrity of the stake and cause them to be structurally unsuitable. Each wooden stake shall be 2"X2"X24", and shall be driven at least 6" into the ground. Design • The drainage area should not exceed 1 acre, or 0.25 acre per 100 feet of barrier. • Maximum flow path to the barrier should be limited to 100 feet. • For installation near the toe of a slope, consider installing the barrier away from the slope to facilitate cleaning. • To prevent flow behind the barrier, sand bags can be placed perpendicular to the barrier to serve as a cross barrier. • Straw bale barriers are not recommended for concentrated flow, channel flow, or in streams or drainages where runoff volumes and velocities can cause the barriers to wash out. Maintenance • In the construction phase, all BMPs will be inspected every 14 days or within 24 hours of a significant storm event. In the interim phase, BMPs will be inspected every 30 days. • Access to perform maintenance on the BMP shall be provided. • Where the BMP has failed, repair or replacement shall be initiated as soon as possible upon the discovery of the failure. • Straw bales shall be replaced if they become heavily soiled, rotten, or damaged beyond repair. • Sediment that accumulates up -gradient of the straw bale barrier shall be removed when it accumulates to 1/3 of the height of the straw bales. • Straw bales shall remain in place until the disturbance area is stabilized. • Ensure stormwater does not scour under the BMP, and repair washouts as needed. • Remove straw bales when no longer needed. Remove the sediment accumulation. Clean and re -grade the stabilized area as needed. Roles (or bundles. or gross) Tom p U w op. be gmen b4] SI�ke3 aryl tilitithed straw trsle.

Surface Roughening Purpose and Description: Surface roughening is a temporary erosion control practice often used in conjunction with grading. Soil roughening reduces runoff velocity, increases infiltration, reduces erosion, traps sediment, and prepares the soil for seeding or planting by providing moisture and by giving seed an opportunity to hold and germinate. There are several types of surface roughening methods that are described below. Tracking / Track Walking Tracking is a cost effective method that works best in sandy soils and can coincide with grading or contouring activities. Tracking utilizes the equipment's tracks to form pockets which increases surface area to promote water absorption and reduces erosion. These conditions promote seed germination and vegetative growth and tracking is often used before seeding takes place. Machinery should create indentations in the ground that are perpendicular to the flow or slope, or along the contours of the grade, resulting in the machinery operating up and down the slope and not across. Pocking: Pocking utilizes hand tools or a back hoe to create depressions in the ground at a minimum depth of 4 inches. The pockets should be spaced so that each row is alternating with the one down gradient, similar to a checkerboard pattern. The pattern should be positioned in such a way that water leaving one pocket would collect into the pocket in the down gradient row which reduces water velocity and erosion. Surface Roughening: Surface Roughening utilizes other machinery or attachment such as disks, tillers, spring harrows, or teeth on a front-end loader to create grooves or uneven surfaces that follow along the contours of the grade. The degree or aggressiveness of the technique implemented should correspond to the steepness of the grade and soil type. This method is ideal for grades less than 3:1 where the ground could be used after reclamation or mowed. Maintenance: Roughened areas should be inspected for rilling or erosion after significant storm or runoff events. Surface roughening is not recommended for rocky slopes or in soils that can be excessively compacted. Heavy storm events can wash out roughened or pocketed surfaces and additional roughening and seeding could be necessary. Temporary Slope Drains Photo View Description and Purpose: A temporary slope drain is a flexible conduit or pipe that drains water down a slope, preventing erosion and surface runoff on or below the slope face. Slope drains generally prevent rill and gully formation, and effectively transport stormwater from a pad or other disturbance area. Most drains consist of plastic or another heavy-duty material manufactured for the purpose. The slope drain BMP generally remains in place until other permanent drainage structures are installed, or the slopes are permanently stabilized. Installation: • Slope drains should be utilized for temporary use unless the structure is properly built to be utilized on a permanent basis. • The drainage conduit should be at least twelve (12) inches in diameter, and sized as needed to convey stormwater flows. • The conduit should be securely fastened together and have water tight fittings. The conduit should also be securely anchored to the slope face or buried as necessary. • The slope should be three (3) percent or steeper. • Stormwater should be directed into the conduit using an end section or a berm. The top of the berm over the conduit should be at least six (6) inches higher than the top of the conduit to ensure no stormwater moves onto the slope face. • The conduit should continue beyond the toe of the slope, and drain onto an erosion control surface, such as a riprap scour pad. • The slope drain will be capped or plugged to allow manual draining only. Inspection and Maintenance: • In the construction phase, all BMPs will be inspected every 14 days or within 24 hours of a significant storm event. In the interim phase, BMPs will be inspected every 30 days. • Large debris, trash and leaves should be removed from the conduit inlets during inspections. • Inspections should determine if the conduit capacity has been exceeded or if any blockages have occurred. • Make certain stormwater is not undermining or scouring around the flared inlet. • Ensure the end section or berm directing the runoff into the conduit is functioning, and no stormwater is moving onto the slope face. • All repairs should be made as soon as possible. • Replace or repair any rock or erosion control material placed at the slope drain outlet. Ensure stormwater is being directed to an intended location or drainage upon leaving the slope drain. • Reroute any construction equipment around the slope drain to avoid damage. • Temporary slope drains should be removed as soon as permanent structures can be installed, or the slope face has reached final stabilization. Topsoil Description and Purpose: Proper handling and storage of topsoil is critical to successful vegetation. Topsoil contains soil microbes and viable seed banks of the native plants that are on the site. Many native plants species depend upon the activity of soil microbes for germination. Handling: The top 4-6 inches depending on soil type of the disturbed location shall be considered topsoil. Topsoil should be segregated from the trench and spoil storage to prevent mixing of different soils. Topsoil stockpiles are to be in separate piles from other soil horizons with stable slopes and be positioned to minimize exposure to wind and water erosion; such as by providing breaks in the stockpiles at drainage crossings to allow drainage where rundown and run off is anticipated. In areas where space is limited and topsoil and spoils cannot be segregated a layer of straw may be used to segregate the two piles. Topsoil piles stored for long periods of time will be seeded with the proper seed mix to provide cover, maintain soil fungi and microbe communities, and to reduce erosion. Redistribution: Once construction is completed topsoil piles will be redistributed in the proper order; with trench spoils first; subsoil's second; and then topsoil may be applied. During redistribution of topsoil onto the pipeline ROW; soil should be graded; re-contoured; and properly blended with the surrounding landscaping and to reestablish natural drainage patterns. Velocity Reducer Description and Purpose: Velocity reducers can be used during site development to manage water quality as well as quantity for drainage areas consisting of 5 acres or less. Velocity reducers are ideal for areas where access for maintenance is minimal and undesirable. The purpose of the velocity reducer is to decrease stormwater velocity, usually from run-on, to minimize on site degradation. Ideally, velocity reducers are installed in historic drainages where run-on will flow through the disturbance area. Velocity reducers shall decrease stormwater flow, eliminating downcutting and supporting the drainage bank stabilization. Velocity reducers vary in shape and sizes but consist of an impoundment type area, which slows water velocity, and rock or geotextile erosion control material "spillway" to help minimize erosion from one velocity reducer to the next. Installation: Greater surface area increases the velocity reduction efficiency. Velocity reducers can vary in size and shape depending on site conditions, drainage acreage, and area of disturbance. A minimum ratio of 3L:2W should be utilized if conditions allow. The front of the velocity reducer should be compacted and a slight impression left to allow for drainage to following reducer. Maintenance: Velocity reducers should be installed as a temporary BMP that over time will eventually silt up. At that time, the disturbance should be vegetated enough to allow for natural drainage features to form and stabilize. Maintenance to the BMP would only be necessary if sediment begins to leave the site. Water Bars Description and Purpose A water bar is made of earthen fill, mound -trench built into a road, pipeline right-of-way (ROW) or any other linear project. Water bars reduce damage from erosion by collecting and redistributing surface runoff to stable outlets at slower speeds and by increasing the distance of overland runoff flow. Implementation Water bars are to be implemented at a degree down slope position relative to the relief and layout of the linear project. Water bars are to be constructed using a bulldozer or road grater. The water bar should be built such that the uphill end of the bar ties into any adjacent bank, cut wall or preserved existing vegetation to receive ditch flow. An energy absorber on the down slope outfall, such as riprap, brush, native vegetative filter and the like, will serve to slow and dissipate the water's energy. When installed in series, the number used is dependent on the slope of the site/surrounding area and should generally proceed as follows or as site conditions allow and as necessary to capture runoff and minimize erosion: Grade (Degrees) Spacing (feet) between Water Bars 2 5 10 15 20 30+ 250 135 80 60 45 35 Water bars should be armored under circumstances of steep grades. The BMP should be also be stabilized with seeding/mulching with a mixture determined/agreed upon by an appropriate party. Inspection and Maintenance In construction phase BMPs will be inspected every 14 days or within 24 hours of a significant storm event. In interim phase BMPs will be inspected every 30 days. Repair major rills to ensure that excessive seepage or surface runoff is not a problem. If sediment traps are used, check for sediment load and erosion around over flow. Wattles Description and Purpose: A wattle (also called a fiber roll) functions as a sediment control barrier for small drainage areas, utilized to protect slopes and small drainages from erosive forces. Wattles are generally made of bound straw material, but can consist of bound rock, coconut, wood chips or other materials. Wattles placed on the face of slopes help intercept runoff, reduce flow velocities, and provide removal of sediment from the runoff. The wattles interrupt the length of a slope and help reduce erosion. Wattles do not function to filter run-off, and will not promote flows penetrating their material. Their function is restricted to ponding run-off and overtopping. Wattles placed in light run-off drainages with sheet flows slow water velocities and prevent run-off concentration. The wattles help prevent drainage scour, and capture sediment. Installation: • Wattles shall be installed on the drainage contour where possible. • The rolls shall be trenched in below grade by two (2) to four (4) inches, and backfilled to ensure run-off will not scour under the BMP. • Wattles shall be secured every four (4) feet along the length of the roll with a stake. The stakes shall be sunk at least six (6) inches below grade. The ends of the wattle should also be staked. • All wattles shall be tied at the ends, and adequately overlapped at their joints when placed side-by-side. • Suggested spacing of wattles for use of permanent slopes is as follows: o Slope inclination of 4:1 (H:V) or flatter: Wattles should be placed at a maximum interval of 20 feet. o Slope inclination between 4:1 and 2:1: Wattles should be placed at a maximum interval of 15 feet. (A closer spacing is more effective). o Slope inclination of 2:1 or greater: Wattles should be placed at a maximum interval of 10 feet. (A closer spacing is more effective). • The ends of the wattles should be turned up slope to prevent run-off from going around the ends of the roll. Inspection and Maintenance: • In the construction phase, all BMPs will be inspected every 14 days or within 24 hours of a significant storm event. In the interim phase, BMPs will be inspected every 30 days. • Verify the wattles remain intact and secure. • Ensure run-off is not undermining or scouring under the BMP. • Wattles cannot be flattened by equipment traffic, materials, or overwhelmed with sediment accumulation. • Sediment should be removed when sediment accumulation reaches one-half the designated sediment storage depth. • Damaged wattles require repairs, replacement or removal. o Split, torn, unraveling, flattened, saturated or slumping rolls require maintenance. • Once a wattle is no longer necessary, it should be removed. o All collected sediment should be disposed of, and any holes, trenches or ground disturbances should be repaired to blend with the adjacent ground.
