Applicant Xcel Energy Jennifer Chester Manager, Siting & Land Rights 1800 Larimer Street, Suite 400 Denver, CO 80202 303-285-6533 Jennifer.L.Chester@XcelEnergy.com Consultant Burns & McDonnell Engineering Company, Inc. Brooke Hines Project Manager 9191 S. Jamaica Street TEMPORARY USE PERMIT APPLICATION 8 Englewood, CO 80112 720-592-3402 bahines@burnsmcd.com 4.1 Applicant That is Not the Property Owner Xcel Energy has secured an easement agreement with the property owner. The redacted and signed TCE for the Yard is provided in Attachment C. 5 TEMPORARY USE DESCRIPTION The Murray Yard, located in Garfield County, is situated on the west side of Chair Bar Road, immediately south of County Road (CR) 346, and approximately 2 miles southwest of Silt, Colorado. The Murray Yard is located approximately 0.3 miles south of the existing 6584 Transmission Line. A Site Plan showing the layout of the equipment and vehicle traffic control (VTC) points is located in Attachment H. The Murray Yard will be used for the delivery, storage, and distribution of materials to support the rebuild Project. Clearing of vegetation and grading will be necessary to level the approximate 2-acre stabilized surface area (SSA) (Attachment H). Best Management Practices (BMPs) will be implemented to control erosion and run-off, reducing stormwater-related impacts to nearby waterbodies. With implementation of BMPs, minimal impacts to existing drainage due to erosion and runoff would occur. A Drainage Memo is included in Attachment I. Any existing drainage structures such as culverts or ditches would be preserved and protected. No wastewater management or water supply will be needed during the proposed temporary use. Portable toilets, handwashing stations, and dumpsters that are contained will be placed in the Murray Yard for sanitation and the Murray Yard will be fenced for security. Wind erosion control BMPs including the application of water or other dust palliatives will be applied to control airborne dust emissions. A spill prevention and response plan will be implemented to prevent and control potential spills of hazardous materials such as fuels, transmission fluid, and petroleum products used in equipment and vehicles. Following completion of construction, Xcel Energy will remove all equipment and any leftover material and restore the Murray Yard generally consistent with preconstruction conditions, and as required by the easement agreement. Materials for the transmission line rebuild are anticipated to be delivered to the Murray Yard beginning in the fall of 2024. Xcel Energy requests that Garfield County accommodate the use period of the Murray Yard to trigger with a pre-construction meeting. Prior to and during construction, deliveries will be made to the Murray Yard from the existing Rising Tides Yard located in Mesa County. When construction begins in Fall 2024, these materials will be transported to certain locations along the ROW TEMPORARY USE PERMIT APPLICATION 9 easement by flat-bed trucks or semi-trucks. During construction, up to 20 vehicle trips (round trips) to and from the Murray Yard could be required each day. These deliveries will be by semi-truck or other delivery vehicle over the course of the six-month period during construction. Vehicles, equipment, and materials will also be parked and stored during the period of use. Equipment and materials to be stored in the Murray Yard will consist of small cranes, bucket trucks, replacement structure components, material pallets, conductor reels, and other transmission line materials and equipment required for the Project. Table 5-1 details the approximate daily roundtrips from the Murray Yard for each component of construction.

As of September 16, 2024, the L&E resolution has not been issued and therefore, a copy of the approval document is not included in this TUP application. TEMPORARY USE PERMIT APPLICATION 12 7 IMPACT ANALYSIS AND PROPOSED MITIGATION The Murray Yard is located on a parcel that is zoned Rural. Temporary uses, such as the Murray Yard, are allowed in any zone district pursuant to Section 3-401.D of the Code. Potential impacts resulting from use of the Murray Yard would be temporary and limited to the construction phase. A description of the potential short-term impacts of the Murray Yard to adjacent properties, infrastructure, and the environment and a description of how the impacts will be mitigated so the standards in Section 7-1301 of the Code will be met, is provided in Table 7-1. Additional details describing compliance with the Section 7-1301 standards are provided in Attachment K. TEMPORARY USE PERMIT APPLICATION 13 Table 7-1: Anticipated Impacts and Mitigation Topic Short-term Impacts Best Management Practices Air Quality Air emissions and low-level fugitive dust will occur from the use of mobile construction equipment as materials are delivered to and from the parcel. Dust will be controlled through the application of water to roads and the Murray Yard during activities. Biological Resources Increased noise and equipment movement during material deliveries may temporarily displace mobile wildlife species. Normal wildlife movements are expected to resume after the temporary use has been completed and disturbed areas have been restored in a manner generally similar to preconstruction conditions. If construction is scheduled to occur during raptor breeding season, raptor nest surveys will be conducted prior to construction to determine whether active nests are present near the parcel. Xcel Energy is coordinating with Colorado Parks and Wildlife (CPW) regarding strategies to avoid, minimize, and mitigate adverse effects to wildlife habitats. The comment letter received from CPW is provided in Attachment L. Cultural Resources Adverse impacts are not anticipated. The Unanticipated Discovery Plan for the Project will be followed if archaeological materials or human remains are discovered during use of the Murray Yard. Land Use Adverse impacts are not anticipated. Land use in the surrounding area includes rural residential areas, agricultural resource lands, agricultural production areas, and natural resource areas zoned as Rural. The proposed temporary use is compatible with the designated zoning. Noise Noise from the use of construction equipment is expected. Construction vehicles and equipment will be maintained in proper operating condition and equipped with manufacturer’s standard noise control devices (e.g., mufflers or engine enclosures). Noise will not exceed state noise TEMPORARY USE PERMIT APPLICATION 14 standards pursuant to Colorado Revised Statutes, Article 12 of Title 25. Natural and Geologic Hazards Adverse impacts are not anticipated. The temporary use is not within any avalanche, landslide, rockfall or alluvial fan hazard areas, and steep slopes are absent. The parcel is free of corrosive or expansive soils and rock and no mudflow or fault areas are present. The temporary use is not anticipated to divert debris flow or floodwaters. Any land disturbed during construction will be restored in a manner generally similar to its condition prior to construction. In the rare event of a fire emergency, Xcel Energy will likely be aware of an issue before the general public or emergency responders. Nevertheless, the public is encouraged to contact Xcel Energy’s emergency number: 800-895-1999 with any concerns or in case of an emergency. Each construction vehicle will be equipped with fire mitigation tools, shovels, a pick axe, portable water cans and fire extinguishers. Additionally, a water truck will be located at the Murray Yard. Xcel Energy will coordinate closely with the local fire department and first responders and consult with them to discuss any concerns within their response area. Xcel Energy offers free online safety training to fire departments and first responders that is based on national standards through its Responding to Utility Emergencies Program. Socioeconomic Adverse impacts are not anticipated. Given the relatively small size of the crews needed for construction and the temporary nature of the construction activities, no impacts to availability of TEMPORARY USE PERMIT APPLICATION 15 public resources and services are anticipated. During construction, revenue may moderately increase for some local businesses, such as restaurants, gas stations, grocery stores, and hotels as well as other local businesses due to spending by Xcel Energy’s contractors or employees. Soils Soil disturbance will result from vegetation clearing and mobile construction equipment traveling to and from the parcel. Xcel Energy will manage any soil impacts on the parcel by strictly adhering to a CDPHE-regulated Stormwater Management Plan (SWMP) and will implement and maintain erosion and sediment control BMPs designed to protect soils and control erosion. Xcel Energy will secure the necessary permits to comply with Garfield County regulations including grading, stormwater, and erosion control permits. A Drainage Memo is included in Attachment I. Toxic and Hazardous Substances Refueling operations may occur onsite. Refueling operations will follow all applicable federal, state, and local regulatory requirements for spill prevention and hazardous material management. Activities will follow BMPs for the management of wastes to avoid and minimize effects from potential spills or other releases to the environment. Transportation Temporary impacts due to increased presence of vehicles, including personal vehicles, delivery trucks and semis, are expected. The roads accessing the parcel have the capacity to efficiently and safely service the additional traffic that will be generated and will not cause traffic congestion or unsafe conditions. Any damage to roads will be mitigated through repair by Xcel Energy to pre-existing conditions. Vegetation Vegetation removal on the site will be necessary. Measures will be implemented to prevent the spread and introduction of noxious weeds and non- native vegetation. Disturbed areas will be restored TEMPORARY USE PERMIT APPLICATION 16 in a manner generally similar to preconstruction conditions and as may be provided for in private agreements. This work may include fence repair, rut removal, decompaction, tilling, seeding, and stabilization measures. A Landscaping Plan is not proposed as part of this application; however, a Revegetation Plan is provided in Attachment M. Visual Resources Temporary visual disturbance will occur during use of the Yard due to the presence of vehicles, equipment, and materials. Vegetation on the site will be removed prior to use. The Murray Yard will be fenced for security and visual screening and upon completion of construction, all equipment will be removed, and the Murray Yard will be restored generally consistent with preconstruction conditions. Waste Construction waste and portable temporary bathrooms will be onsite during the construction period. Enclosed containment will be provided for trash disposal. Construction waste, including trash and litter, garbage, other solid waste, petroleum products, and other potentially hazardous materials, will be removed and taken to a disposal facility authorized to accept such materials. Activities will follow BMPs for the management of waste to avoid and minimize effects from potential spills or other releases to the environment. Portable temporary bathrooms will be serviced on a regular basis. Water Resources Adverse impacts are not anticipated. A stream is located in the northwest corner of the parcel. The temporary use will not affect wetlands or other surface waters in the vicinity and is not anticipated to divert debris flow or floodwaters. BMPs will be implemented to reduce stormwater- related impacts to nearby waterbodies in compliance with Colorado Department of Public Health and Environment (CDPHE) regulations. TEMPORARY USE PERMIT APPLICATION 17 8 COMPLIANCE WITH ARTICLE 7 STANDARDS Attachment K details how the Yard conforms with applicable Article 7 Standards, specifically Divisions 1-3 and Section 7-1301. 9 CONFORMANCE WITH REVIEW CRITERIA IN SECTION 4-120 Section 4-120.A of the Code establishes Review Criteria for TUP applications as follows: The Director shall review the Temporary Use Permit application to determine if the application satisfies the applicable standards of Article 7. Attachment K provides the required information to conform with the applicable standards of Article 7 of the Code. 10 WAIVER REQUESTS Xcel Energy is not requesting any waivers from the submittal requirements outlined in Section 4-202 or from the Article 7 Standards. 11 PROFESSIONAL QUALIFICATIONS Table 11-1 details the professional qualifications for preparation and certification of certain documents included in this permit application.

GENERAL PROJECT DESCRIPTION Garfield County’s Land Use and Development Code is available here: https://www.garfield- county.com/community-development/land-use-code/ Temporary Use Permits are described in Section 4-120 and Section 7-1303. The following sections of this preapplication conference summary contain general submittal requirements and process outlines. The Director has indicated that he will refer these Temporary Use applications to the Board of County Commissioners for their decision. Applications for a Temporary Use should be submitted at least 60 days prior to the proposed use. Temporary Use Permits are restricted to a 6-month period and cannot be applied for on the same property more than twice in one 12 month period. There are noticing requirements which will include the start date, operating hours, and duration of the uses. Authorization of property owners needs to be included in compliance with 4-120.B.2.a. Recorded Statements of Authority need to be provided for any LLCs, trusts, or similar entities. The applications should directly respond to items found in 4-120.B.5. Impacts on neighboring properties and infrastructure will be taken into account, so the application should address these 2 topics specifically. The application should address Article 7 Standards. Divisions 1-3 and Section 7- 1301 should be specifically addressed. Any previous approvals on a parcel should be included with an application, and the application should demonstrate continued compliance with those approvals. The applications should provide information such as location, site plans, haul routes, helicopter flight paths, hours of operation, start date, duration, uses, site preparation, and site restoration. Stormwater and traffic should be addressed. If hazardous materials will be stored on site, mitigation practices should be provided to address. Wastewater management systems and water supply should also be addressed. Garfield County’s Environmental Health handles vault and haul permits for those types of wastewater systems. XCEL is undertaking multiple rebuilds of transmission lines throughout Garfield County. At this time, three broad phases are anticipated. Each will have laydown yards that double as helistops to facilitate installation of new poles in difficult terrain. Each yard should have a separate application, though staff will coordinate the review of the applications to minimize review times and hearings. Helicopter deliveries involve FAA approvals. The applications should provide information on these approvals and what mitigation activities will be involved to limit hazards to residents. Glenwood Springs - Mitchell Creek Rebuild which currently has an Location and Extent application under review; will have a single laydown/helistop in unincorporated Garfield County on parcel 218505400065. This yard will primarily be used for storage for helicopter delivery. Steep slopes to the south of this site exist, and access is taken from existing private roads/driveways. The application should demonstrate the adequacy of these systems for the proposed uses. This segment is mostly within incorporated Glenwood Springs. It does cross I70 and the Colorado River, though at this time helicopter operations will be north of these barriers. 6584 Mitchell Creel – Rifle Ute Transmission This 25 mile rebuild is scheduled for 2025 and will have 5 staging areas. Each of these laydown yards will also have helicopter activity. This section may be broken up into two small sections. This section is primarily south of I-70. A map is shown on the following pages. The applicant may need to schedule an update to this preapplication conference summary for this area as they approach the 2025 time frame. A variety of different scale of laydown yard are proposed in this section. Each application should provide specific details on the intensity of its uses to allow for the adequate review of possible impacts on infrastructure and neighbors. 6670 Rifle Ute - De Beque Transmission: This rebuild of approximately 32 miles currently has 2 proposed laydown/helistop facilities. This section is mostly north of the I-70. These facilities will primarily be fly yards with no or limited overnight storage. Materials are expected to be delivered to the sites and then taken from the facility to the construction site the same day. A project overview map is provided on the following pages. 3 Figure 2 6584 Mitchell Creel – Rifle Ute Transmission Figure 1 Glenwood Springs - Mitchell Creek Rebuild 4 Figure 3 6670 Rifle Ute - De Beque Transmission: II. COMPREHENSIVE PLAN Compliance with the comprehensive plan should be shown by any application, though for temporary uses the application may want to focus on the lack of long term impacts and limiting longer negative impacts of alternatives. III.

Under certain conditions, not installing a CM may be the best approach to minimize sediment transport off site. This is based on the concept that shallow overland flow may pick-up and transport sediment that is then dropped out within a vegetative buffer depending on a variety of site conditions. Use of VT instead of a structural CM is dependent on the following factors: x Rainfall – Rainfall intensity impacts the buffer distance. The rainfall rate across the site has been calculated to be calculated 1.19” to 1.25” in a 5-year, 30-minute storm. A 1.25” 5-year, 30-minute storm was utilized for model inputs. This rainfall depth is incorporated in the Table 1 distances. x 80% sediment removal – structural CMs target 80% sediment removal. Actual removal rates vary but have been shown to be less than 80% in many studies. The 80% removal rate is one basis for the VT buffer distances reported in Table 1. x Disturbance area does not have concentrated flow – This approach is based on sediment dropping out while suspended in an overland sheet flow condition. If there is concentrated flow prior to or due to construction, i.e. rill erosion across the work/disturbance area that continues down-gradient and off-site, then structural CMs are recommended. x Low slope – local slope of the site impacts velocity, flow concentration, and other factors. Use VT should not be considered for slopes exceeding 10%. x Soil Type – Soil type impacts likelihood of soil being transported in sheet flow. The larger the soil particles, i.e. sand, the harder to pick-up and transport. The smaller the particle, i.e. clay, the longer the transport distance. The NRCS predominant Hydrologic Soil Group (HSG) soil types for the project area are A and B. The hydrologic soil groups (HSG) are A – D and as follows: o A – sand or silty sand, High infiltration rate o B – sandy silt, moderately high infiltration rate o C – clayey silt, moderate to low infiltration rate July 5, 2024 Xcel 6584 MITC-UTER Material Yard o D ʹ clay, low infiltration rate x Vegetation cover – The vegetation cover (surface roughness) was accounted for in the VT model runs and found to provide similar buffer distances, therefore the most conservative vegetation density is reflected in Table1. x Vegetation Buffer - The buffer distance measurement is along the flow direction, and measured from the limit of the work zone to the limit of the utility easement/ROW. Vegetation buffer outside of the ROW may not be utilized for the required buffer distance. Due to the project area, there is adequate area for sediment settling on-site. x The use of this VT approach may be applied to linear and larger area disturbances that meet the parameters described in this memo. x Table 1 results below include a 15% buffer beyond calculated model buffer distances. Utilize Table 1 below for VT buffer distances. Buffer distances are an extrapolation of the ¾” and 1” rainfalls to a 1.25” rainfall. VT Buffer Soil Buffer Distance (ft) A 3 B 8 C 34 D 66 Maintenance: In the same manner that using existing conditions as a CM does not require installation of a CM, there is no maintenance of this CM. VT is either adequate or structural CMs should be installed. Inspection: Like structural CMs, the area down gradient of a VT CM should be walked and observed for the following which indicate that VT may not be adequate: x signs of new rill erosion in work area or immediately down gradient of work area x signs of sediment deposition well beyond the expected buffer distance or nearing area not controlled by Xcel property lease x observations of work area or up gradient areas that are creating concentrated flow through and down gradient of the work area. x Observe and discuss with contractor potential construction practic es that could promote sheet flow and infiltration to minimize stormwater runoff from work area. In the event that VT is inadequate to keep sediment on site at any local area, that local area mu st immediately have a structural down gradient CM installed, a t a minimum. Sediment Control Log is the expected control measure. Site conditions will dictate actual CM to be used. Note: Sediment Control Logs cannot be used in across swales or drainageways. Xcel 6584 MITC-UTER Murray Yard AUGUST 2024 August 6, 2024 Hydrologic Soil Group for the site is type C. TRANSMISSION LINE 6584 REBUILD PROJECT ATTACHMENT I: Drainage Memo 1 Memo Date: Wednesday, August 14, 2024 Project: 6584 TLine: Mitchell (MITC) - Rifle (UTER) Electric Transmission Line Rebuild - McLin and Murray Staging Areas. To: Garfield County From: Brian Brown – HDR Engineering Subject: Drainage Memo for Staging Yards – Murray and McLin Public Service Company of Colorado (PSCo), a Colorado corporation conducting business as Xcel Energy (Xcel), is proposing to rebuild a 25-mile segment of a 69-kilovolt (kV) overhead transmission line from the Mitchell Creek Substation within the City of Glenwood Springs and unincorporated Garfield County, Colorado to the Rifle Ute Substation in unincorporated Ga rfield County. In support of this line rebuild, Xcel has secured two staging/material yards to store equipment, perform limited equipment assembly, and provide a meeting place for construction crews . The impact to surface drainage at the Murray Yard and the McLin Yard is the focus of this memo. See Site plans submitted in support of this project for a figure that includes location of the line and the Murray and McLin s taging yards. Existing Conditions: The Murray Yard (36 acres) and McLin Yard (15 acres) are both in Garfield County and are undeveloped parcels with varying slopes from gentle to nearly level and vegetation density from sparse (majority of the Murray Yard) to moderately dense (McLin Yard). While both yards have had utility improvements, buried gas and overhead power for Murray and buried irrigation for McLin, neither yard has existing improvements that substantively impact surface stormwater flow or change the surface flow type or direction. Proposed Temporary Conditions: The proposed improvements for both the Murray and McLin Yards will be temporary with the installation of a 2-acre aggregate surfaced Stabilized Staging Area (SSA) at each yard that will be constructed to generally match the existing grades of the site. The SSA is to minimize impacts to water quality by minimizing rutting and uncontrolled surface disturbance that can lead to sediment transport off-site and track out onto adjoining roads. The SSA is temporary and will be removed once construction is complete and the site topsoil will be restored to generally match pre -construction grades. After the 2 seeding and mulch and with adequate moisture and time for germination and vegetation growth, the slopes, soil types, and vegetation cover will generally match the pre -construction conditions. The portion of the Yard outside of the SSA will remain in the pre -construction condition and will be accessed without grading modification. Access will be overland in a manner described as ‘drive and crush’. This limited drive and crush access will temporarily impact surface foliage but generally keeps the plant ’s root structure in place which maintains current soil loss rates (erosion rates) and allows for a rapid rebound of the plant community. This drive and crush approach typically maintains the current surface runoff rates and flow types. Outcome: At the closure of the County Grading Permit and the State Stormwater Management Plan (SWMP) Permit, the site grades and vegetation density will generally match the pre -construction conditions. Therefore, there will be no permanent change to surface drainage within either the Murray Yard nor the McLin Yard compared to pre-construction surface drainage. This project will not permanently change the existing surface water flow paths, overall slopes, impervious surface area, nor time of concentration and therefore will not change the runoff volume, runoff peak, nor conveyance path for either Yard.

6584 Mitchell Creek to Ute Rifle Rebuild Garfield County, Colorado TRANSMISSION LINE 6584 REBUILD PROJECT ATTACHMENT K: Compliance with Article 7 Standards Garfield County Land Use and Development Code Article 7: Standards DIVISION 1: GENERAL APPROVAL STANDARDS 7-101. ZONE DISTRICT USE REGULATIONS The parcel to be utilized for the Murray Yard is currently zoned as Rural (R). Temporary uses are allowed in any zone district pursuant to Section 3-401.D of the Land Use and Development Code. Article 3 of the Garfield County Land Use and Development Code states that the Rural Zone District is “intended to protect the existing character of the area from uncontrolled and unmitigated residential, commercial and industrial use. The zone district provides for the use of natural resources, recreational development, rural residential, and other uses.” (Garfield County 2023). The Murray Yard will not conflict with the zone district use regulations, will be used on a temporary basis, and will be restored and returned to its pre-construction use and condition at the end of the Project. 7-102. COMPREHENSIVE PLAN AND INTERGOVERNMENTAL AGREEMENTS The Garfield County Comprehensive Plan was developed for the general purpose of guiding and accomplishing a coordinated and harmonious development of the relevant territory, which, in accordance with present and future needs and resources, will best promote the general welfare of the inhabitants (Garfield County, 2020). The Vision for Garfield County is dedicated to managing and directing growth to dedicated Urban Growth Areas (UGAs) and other areas that can accommodate growth cost effectively, in order to create thriving communities while promoting a diverse, sustainable and healthy economy, protecting wildlife, maintaining or improving the quality of the natural environment, and preserving the County’s rural and western heritage (Garfield County, 2020). The proposed temporary use is in support of a transmission line rebuild project that will strengthen existing infrastructure and provide continued reliable energy service to Garfield County, supporting the growth of industrial, commercial, and residential uses in the surrounding areas. The temporary use will support the 6584 Transmission Line Rebuild Project (Project) that will revitalize and strengthen electric infrastructure in Garfield County to meet future demand resulting from development encouraged in the Garfield County Comprehensive Plan. The temporary use will not create any new negative impacts to open space, scenic vistas, public trails, and other recreational opportunities and will preserve these elements in Garfield County. There will be no long-term negative visual impact to the surrounding community resulting from the temporary use because the parcel will be restored in a manner generally similar to preconstruction conditions. Any required environmental permits and approvals will be acquired prior to construction and any conditions of approval, including environmental mitigation measures, will be implemented to protect the natural environment. The temporary use will occur on a previously developed parcel of land, reducing impacts to surrounding land use and resources. No intergovernmental agreements are applicable to the use of the Murray Yard or the Project. 7-103. COMPATIBILITY The nature, scale, and intensity of the proposed temporary use is compatible with surrounding land uses, which include rural residential areas, agricultural resource lands, agricultural production areas, and natural resource areas. Temporary staging areas are routinely sited in Rural areas and the temporary use will occur on a previously developed parcel of land. The surrounding parcels are also zoned Rural. 7-104. SOURCE OF WATER This land use will not require an onsite source of water for the temporary use. Some water use from outside sources will be necessary to control dust emissions in the Murray Yard, to service portable toilets, and to provide bottled drinking water to the workforce. 7-105. CENTRAL WATER DISTRIBUTION AND WASTEWATER SYSTEMS Central water distribution and wastewater systems are not required for the temporary use proposed. Portable toilets and hand washing stations will be provided, and water for consumption will be purchased and brought onsite from outside sources to be consumed during construction. 7-106. PUBLIC UTILITIES No public utilities will be required during temporary use of the parcel. The primary use of the parcel will be storage, staging, and delivery of materials and equipment to support the Project. 7-107. ACCESS AND ROADWAYS Access to the Murray Yard will be from Chair Bar Road. No new roads will be created. Where road improvements are needed, Xcel Energy will secure the necessary permits to comply with Garfield County regulations including grading, stormwater, and erosion control permits. Due to its rural location, the roads accessing the parcel have the capacity to efficiently and safely service the additional and temporary traffic that will be generated and will not cause traffic congestion or unsafe conditions. There will be impacts due to increased presence of vehicles, including personal vehicles, delivery trucks and semis, but this impact will be temporary. 7-108. USE OF LAND SUBJECT TO NATURAL HAZARDS The Murray Yard is not located in an area with identified Natural and Geologic Hazards, such as falling rock, landslides, snow slides, mud flows, radiation, flooding, or high-water tables. The Murray Yard is being used on a temporary basis and not permanently developed, therefore no elimination or mitigation of potential effects for hazardous conditions are necessary. Once construction has been completed, the Murray Yard will be restored in a manner generally similar to its condition prior to construction and as may be provided for in private agreements. 7-109. FIRE PROTECTION Adequate fire protection will be provided for the Murray Yard by the Colorado River Fire Rescue Protection District. Xcel Energy will coordinate with the Colorado River Fire Rescue Protection District prior to the proposed temporary use. Measures to prevent and control fires during the proposed temporary use will be implemented in accordance with Garfield County and Colorado River Fire Rescue Protection District requirements. Xcel Energy offers free online safety training to fire departments and first responders that is based on national standards through its Responding to Utility Emergencies Program. DIVISION 2: GENERAL RESOURCE PROTECTION STANDARDS 7-201. AGRICULTURAL LANDS It is not anticipated that activities at the Murray Yard will adversely affect agricultural operations, nor is any division or development of land proposed as a part of those activities. Uses within the Murray Yard will be limited to construction activities. After construction of the transmission line, the Murray Yard will be restored and returned to its pre-construction use. Dogs or other domestic animals that may interfere with livestock will not be permitted on site during temporary use. Any fences and gates present will be protected and left in the condition they are found or repaired as soon as reasonably possible by Xcel Energy and its contractors. Any damage to roads leading into the parcel will be repaired by Xcel Energy, including any fences that may be damaged. Dust control will be implemented during temporary use via water applications to minimize impacts to livestock and crops in the area. 7-202. WILDLIFE HABITAT AREAS Potential impacts to wildlife habitat will be temporary and limited to the parcel and established access roads. Increased noise and equipment movement during material deliveries may temporarily displace mobile wildlife species from the immediate workspace area. These impacts are considered short-term in duration and normal wildlife movements will be expected to resume after the temporary use has been completed and disturbed areas have been restored in a manner generally similar to preconstruction conditions. Changes to species composition, number of threatened and endangered species, species habitat, and the food web are not expected due to the temporary nature of the use. In areas where grading is necessary, Xcel Energy will implement measures to prevent the spread and introduction of noxious weeds and non-native vegetation and revegetate disturbed areas following construction in a manner generally similar to preconstruction conditions. No trees exist on the parcel, however, if construction is scheduled to occur during raptor breeding season, raptor nest surveys will be conducted prior to construction to determine whether active nests are present near the parcel. 7-203. PROTECTION OF WATERBODIES A stream is located in the northwest corner of the parcel. The temporary use will not affect wetlands or other surface waters in the vicinity and is not anticipated to divert debris flow or floodwaters. Best Management Practices (BMPs) will be implemented to reduce stormwater-related impacts to nearby waterbodies in compliance with Colorado Department of Public Health and Environment (CDPHE) regulations. 7-204. DRAINAGE AND EROSION Xcel Energy will manage any soil impacts on the parcel by strictly adhering to a CDPHE-regulated Stormwater Management Plan (SWMP) and will implement and maintain erosion and sediment control BMPs designed to protect soils and control erosion. Xcel Energy will secure the necessary permits to comply with Garfield County regulations including grading, stormwater, and erosion control permits. Xcel Energy can provide copies of the permits to the County, as necessary, prior to the start of construction. A detailed Grading Plan outlining the improvements needed for the temporary use will be provided, as required. 7-205. ENVIRONMENTAL QUALITY The temporary use is not expected to have a significant impact on environmental quality. No significant wetland impacts are anticipated from the temporary use and water quality will not be impacted because Xcel Energy will implement spill and erosion control prevention and clean up measures in accordance with permits. Soil disturbance will result from vegetation clearing and mobile construction equipment traveling to and from the parcel. However, soil will be stabilized with the implementation of erosion control BMPs. Impacts from air emissions and low-level fugitive dust will be short-term and occur primarily from the use of mobile construction equipment as materials are delivered to and from the parcel. Dust will be controlled through the application of water to roads and the Murray Yard during activities. Emissions and dust resulting from the temporary use will not result in air quality reduction below acceptable levels established by the Colorado Air Pollution Control Division. 7-206. WILDFIRE HAZARDS Xcel Energy’s commitment to reducing wildfire risk is outlined in Xcel Energy’s 2020 Wildfire Mitigation Plan (Xcel, 2020). The Murray Yard is within and surrounded by areas with low to moderate Wildfire Susceptibility Index within the Wildland Urban Interface. The temporary use will not create additional risk for wildfire with the implementation of fire prevention BMPs, including having basic firefighting equipment on site and planning and coordination with the Colorado River Fire Rescue Protection District. Vegetation management may be required as part of the temporary use, thereby reducing fuel for wildfires. Xcel Energy will coordinate with local fire departments and first responders and consult with them to discuss any concerns within their response area. 7-207. NATURAL AND GEOLOGIC HAZARDS The Murray Yard is not located in an area with identified Natural and Geologic Hazards. It is not anticipated that the temporary use will have any materially adverse impacts to soil, geologic conditions, or natural hazards as the primary use of the parcel will be storage, staging, and delivery of materials and equipment to support the Project. The temporary use is not within any avalanche, landslide, rockfall or alluvial fan hazard areas, and steep slopes are absent. The parcel is free of corrosive or expansive soils and rock and no mudflow or fault areas are present. The temporary use is not anticipated to divert debris flow or floodwaters. Any land disturbed during construction will be restored in a manner generally similar to preconstruction conditions. 7-208. RECLAMATION Ground disturbance will increase the potential for erosion, such as removal of protective vegetation and exposure to wind and water erosion. Impacts may result from soil disturbance due to construction machinery traveling to and from the parcel and movement of materials, machinery, and vehicles within the parcel. General construction traffic will be limited to designated access roads and the Murray Yard to minimize impacts. BMPs for erosion control will be implemented to minimize erosion and dust emissions resulting from activities associated with the temporary use in accordance with a SWMP. Topsoil will be stockpiled prior to grading for use in reclamation. The areas affected by the temporary use will be reclaimed in accordance with the approved timeline as soon as possible following demobilization to stabilize the area and reduce visual impacts. Reclamation activities will include re-grading to original land contours and placement of topsoil, followed by revegetation with an approved seed mix. A uniform vegetative cover will be established with a density of 70 percent pre-disturbance levels within four growing seasons. Established cover will not include state or Garfield County noxious weeds or alien annual invasive species. A weed management plan will be implemented to control the spread and propagation of listed noxious weeds and invasive species during the temporary use and reclamation activities. DIVISION 3. SITE PLANNING AND DEVELOPMENT STANDARDS 7-301. COMPATIBLE DESIGN Land use in the surrounding area includes rural residential areas, agricultural resource lands, agricultural production areas, and natural resource areas zoned as Rural. The proposed temporary use is compatible with the designated zoning. Land within and surrounding the parcel for the Murray Yard is primarily undeveloped and the temporary use will not impact streets, lots, solar access, parking, pedestrian access, and access to common areas. Operations in the Murray Yard will avoid nuisances to adjacent uses. Any dust, odors, gas, fumes, and glare will not be emitted at levels objectionable to adjacent properties. Noise will not exceed state noise standards pursuant to Colorado Revised Statutes, Article 12 of Title 25. The hours of operations will be 7 days per week and 12 hours per day. The Murray Yard will be enclosed by a fence for security. 7-302. OFF-STREET PARKING AND LOADING STANDARDS No off-street parking or loading standards apply since the proposed temporary use is within an undeveloped rural parcel of land. Parking areas for vehicles and equipment will be confined to designated areas that will not interfere with local traffic or activities within the Murray Yard. All loading and unloading and storage of materials will occur in designated areas on the parcel. The Site Plan provided in Attachment H of the application depicts parking areas. With landowner permission, surface materials may be applied following grading of the parcel to stabilize soils and proper drainage and stormwater BMPs will be applied. 7-303. LANDSCAPING STANDARDS The temporary use will avoid or minimize impacts to vegetation generally as practicable. As discussed in Section 7-208, the Murray Yard will be reclaimed following use to acceptable standards pursuant to the terms of the agreement with the landowner and as approved by Garfield County. No landscape plan will apply because the parcel does not currently have specific landscaping in place and the parcel will be restored in a manner generally similar to preconstruction conditions according to landowner agreement conditions and Garfield County requirements. However, a Revegetation Plan is provided in Attachment M. 7-304. LIGHTING STANDARDS For security purposes, lighting at night in the Murray Yard will be necessary during the proposed temporary use. Lighting will be designed to direct light inward and will be shielded such that concentrated rays of light will not shine directly into other properties. Lighting will not create a traffic hazard and will not include flashing or blinking lights. Light sources will not exceed 40 feet in height. 7-305. SNOW STORAGE STANDARDS A designated snow storage area will be included in the proposed temporary use that will not impede traffic or parking. Since the Murray Yard will be within a rural undeveloped parcel, no snow storage will be in parking spaces or off-street parking or loading areas. Adequate drainage will be provided for snow melt within the parcel and no snow melt will be permitted to drain onto adjacent property. 7-306. TRAIL AND WALKWAY STANDARDS The proposed temporary use will not impact any trails or sidewalks linking to public facilities and no safety or maintenance measures will need to be implemented. OTHER PERTIENT STANDARDS DIVISION 13. ADDITIONAL STANDARDS FOR TEMPORARY USES. 7-1301. TEMPORARY USE A. The applicant, or a member of the applicant’s household, has not applied for a permit for the same or similar use more than twice within the prior twelve (12) month period. Xcel Energy has not previously applied for a TUP for the Murray Yard. B. The use does not result in any negative long-term impact to adjacent properties, public infrastructure, or existing environmental conditions. Adjacent Properties The Murray Yard use will not result in any negative long-term impacts to adjacent properties because the Murray Yard will be restored and returned to the original use upon completion of construction of the Project. Impacts will be limited to short-term impacts associated with construction and are not expected to cause a public nuisance. Any dust, odors, gas, fumes, and glare will not be emitted at levels objectionable to adjacent properties. Impacts and proposed mitigation are described below. Air quality: Impacts from air emissions and low-level fugitive dust will be short-term and occur primarily from the use of mobile construction equipment as materials are delivered to and from the parcel. Dust will be controlled through the application of water to roads and the Murray Yard during activities. Emissions and dust resulting from the temporary use will not result in air quality reduction below acceptable levels established by the Colorado Air Pollution Control Division. Noise: Construction vehicles and equipment will be maintained in proper operating condition and equipped with manufacturer’s standard noise control devices (e.g., mufflers or engine enclosures). Noise will not exceed state noise standards pursuant to Colorado Revised Statutes, Article 12 of Title 25. Light: For security purposes, lighting at night in the Murray Yard will be necessary during the proposed temporary use. Lighting will be designed to direct light inward and will be shielded such that concentrated rays of light will not shine directly into other properties. Lighting will not create a traffic hazard and will not include flashing or blinking lights. Light sources will not exceed 40 feet in height. Stormwater: Xcel Energy will manage any soil impacts on the parcel by strictly adhering to a CDPHE- regulated Stormwater Management Plan (SWMP) and will implement and maintain erosion and sediment control BMPs designed to protect soils and control erosion. Public Infrastructure Local government services, transportation infrastructure, educational facilities, housing, water (other than trucked-in water for construction), sewage and wastewater treatment, public transportation, existing businesses, and social services are adequate to support the proposed use due to the small size of the construction crew and temporary nature of the construction activities. Given the relatively small size of the crews needed for construction of the Project, no impacts to emergency health care facilities or law enforcement services are anticipated. Roads and Traffic: Access to the parcel will be from Chair Bar Road. No new roads will be created. Where road improvements are needed, Xcel Energy will secure the necessary permits to comply with Garfield County regulations including grading, stormwater, and erosion control permits. Due to its rural location, the roads accessing the parcel have the capacity to efficiently and safely service the additional traffic that will be generated and will not cause traffic congestion or unsafe conditions. There will be impacts due to increased presence of vehicles, including personal vehicles, delivery trucks and semis, but this will be temporary. Water and Wastewater: Central water distribution and wastewater systems are not required for the temporary use proposed. Some water use from outside licensed sources will be necessary to control dust emissions in the Murray Yard, to service portable toilets, and to provide bottled drinking water to the workforce. Portable toilets and hand washing stations will be provided, and water for consumption will be purchased and brought onsite from outside sources to be consumed during construction. Public Parks: The Murray Yard is not located near any public parks and will not cause impacts. Existing Environmental Conditions The temporary use is not expected to have a long-term impact on existing environmental conditions. No significant wetland impacts are anticipated from the temporary use and water quality will not be impacted because Xcel Energy will implement spill and erosion control prevention and clean up measures in accordance with permits. Soil disturbance will result from vegetation clearing and mobile construction equipment traveling to and from the parcel. However, soil will be stabilized with the implementation of erosion control BMPs. Impacts from air emissions and low-level fugitive dust will be short-term and occur primarily from the use of mobile construction equipment as materials are delivered to and from the parcel. Dust will be controlled through the application of water to roads and the Murray Yard during activities. Emissions and dust resulting from the temporary use will not result in air quality reduction below acceptable levels established by the Colorado Air Pollution Control Division. C. The use minimized any significant, adverse short-term impact to adjacent properties, public infrastructure, or existing environmental conditions. Short-term impacts are expected to occur during construction and use of the Murray Yard. Short-term impacts and proposed mitigation are discussed above, under Section 7-1301.B and are detailed in Table 7.1 of the application. D. Pedestrian and vehicular traffic associated with the use are not hazardous or conflict with the existing and anticipated traffic in the neighborhood. As discussed above, under Section 7-1301.B, the roads accessing the parcel have the capacity to efficiently and safely service the additional and temporary traffic that will be generated and will not cause traffic congestion or unsafe conditions. E. Utility, drainage, and other necessary facilities to serve the proposed use will be provided. No new or upgraded utilities, drainage or facilities are anticipated to be needed to serve the Murray Yard. Xcel Energy will manage any soil impacts on the parcel by strictly adhering to a CDPHE-regulated Stormwater Management Plan (SWMP) and will implement and maintain erosion and sediment control BMPs designed to protect soils and control erosion. Xcel Energy will secure the necessary permits to comply with Garfield County regulations including grading, stormwater, and erosion control permits. A detailed Grading Plan outlining the improvements needed for the temporary use will be provided, as required. F. The temporary use location protects the public health, safety, welfare, environment, infrastructure, and wildlife resources of Garfield County. Public Health, Safety, and Welfare It is not anticipated that the Murray Yard use will have any impacts to public health, safety or welfare. Environment and Infrastructure Impacts to the environment and infrastructure and proposed mitigation are described above, under Section 7-1301.B. Wildlife Resources Potential impacts to wildlife habitat will be temporary and limited to the parcel and established access roads. Increased noise and equipment movement during material deliveries may temporarily displace mobile wildlife species from the immediate workspace area. These impacts are considered short-term in duration and normal wildlife movements will be expected to resume after the temporary use has been completed and disturbed areas have been restored in a manner generally similar to preconstruction conditions. Changes to species composition, number of threatened and endangered species, species habitat, and the food web are not expected due to the temporary use. In areas where grading is necessary, Xcel Energy will implement measures to prevent the spread and introduction of noxious weeds and non-native vegetation and revegetate disturbed areas following construction in a manner generally similar to preconstruction conditions. No trees exist on the parcel, however, if construction is scheduled to occur during raptor breeding season, raptor nest surveys will be conducted prior to construction to determine whether active nests are present near the parcel. TRANSMISSION LINE 6584 REBUILD PROJECT ATTACHMENT L: Colorado Parks and Wildlife Comment Letter Grand Junction (Area 7) Service Center 711 Independent Ave Grand Junction, CO 81505 P 970.255.6100 | F 970.2556111 Heather Dugan, Acting Director, Colorado Parks and Wildlife Parks and Wildlife Commission: Carrie Besnette Hauser, Chair • Dallas May, Vice-Chair • Marie Haskett, Secretary • Taishya Adams Karen Bailey • Betsy Blecha • Gabriel Otero • Duke Phillips, IV • Richard Reading • James Jay Tutchton • Eden Vardy November 2, 2022 Burns & McDonnell 9785 Maroon Circle, STE 400 Centennial, CO 80112 RE: Xcel Transmission Line Rebuild 6584 Dear Ms. Hines, Thank you for the opportunity to provide comments on the proposed Electric Transmission Line Rebuild of the Mitchell Creek to Rifle Transmission Line 6584 Project (Project). Colorado Parks and Wildlife (CPW) has a statutory responsibility to manage all wildlife species in Colorado. This responsibility is embraced through our mission to perpetuate the wildlife resources of Colorado and provide sustainable outdoor recreation opportunities that educate and inspire future generations. CPW fulfills this mission by responding to requests for comments on wildlife impact reports, land use proposals, and consultations through public- private partnerships. CPW understands from the permit application material that Xcel is replacing approximately 30 miles of 115 kV electrical transmission line from the Mitchel Creek substation to the Rifle Substation in Garfield Counties beginning in 2023. Land ownership within this project area includes public, private, and CPW’s Garfield Creek State Wildlife Area. This Project is a part of a large-scale replacement effort in Western Colorado that has reached the end of its serviceable life. Existing wooden poles will be replaced with single, weathered monopoles resulting in fewer structures than what is currently on the landscape. The proposed alignment will follow the existing alignment with minor re-routes proposed near the City of New Castle. The existing 30-50 foot right of way will be expanded to 75 feet to accommodate design upgrades and installation. Expected construction activities could include ground crews, truck support, line-pulling stations, and helicopter operations with material stored on staging areas throughout the project area although not clearly identified in the project materials. The project proponents briefly address necessary vegetation clearing during construction but do not include a reclamation plan. In reviewing the application material, the Project follows the existing alignment through scrub/shrub wildlife habitat. CPW has identified that this project area is located within the following CPW-mapped High Priority Habitats (HPH) with sound, spatial data and scientifically backed Best Management Practices (BMPs). To protect those habitats listed below, CPW recommends the following best management practices to avoid, minimize, and mitigate adverse impacts to sensitive species within the project area while incorporating logically based flexibility to accommodate the project construction because of its community benefit. • Mule deer severe winter range and winter concentration area: part of the overall range where 90% of the individuals are located when the annual snowpack is at its maximum and/or temperatures are at a minimum in the two worst winters out of ten; and the part of the winter range where densities are at least 200% greater than the surrounding winter range. • Project construction managers should pause work if deer are observed within a 400-meter buffer around the construction area, followed by a call to the District Wildlife Manager to discuss alternative plans. • Communication with CPW to evaluate winter pressures, habitat conditions, and weather patterns should occur weekly or as noticed by construction crews or CPW staff. • Elk Winter range and concentration area: part of the overall range where 90% of the individuals are located when the annual snowpack is at its maximum and/or temperatures are at a minimum in the two worst winters out of ten; and the part of the winter range where densities are at least 200% greater than the surrounding winter range. • Project construction managers should pause work if deer are observed within an 800-meter buffer around the construction area, followed by a call to the District Wildlife Manager to discuss alternative plans. • Communication with CPW to evaluate winter pressures, habitat conditions, and weather patterns should occur weekly or as noticed by construction crews or CPW staff. • Native Species Conservation and Sportfish Management Waters: Ephemeral or intermittent streams and rivers serve as aquatic habitats during periods of flowing water and the absence of flowing water. • Should avoid surface occupancy within 500 feet of the ordinary high-water mark. • During construction and operations, the contractor should prioritize erosion control measures identified within the NPDES Permit to minimize off-site and in-channel sediment transport. • Dust suppression should utilize fresh water only. • Implement a Noxious Weed Management Plan to treat topsoil stockpiles and materials at least bi-annually with spot-treatment as needed utilizing a Colorado-cer tified herbicide applicator. • Erosion control measures will be in place before any ground disturbance such as clearing, grubbing, construction, and reclamation; survey work will be exempt. • Traffic crossing the Native Species Conservation or Sportfish Management Waters should be restricted to a single crossing point to minimize damage to the banks and channel bed. • Protect banks and streambeds by incorporating structure or mat reinforcements. • Sediment collection mechanisms will be installed within the stream bed, including dry channels, and along the banks. • Active Bald Eagle Nest or Roost site: defined as groups of individual trees that provide nesting habitat or diurnal or nocturnal perches and are usually the tallest available trees in the wintering area located primarily in riparian habitats. o No permitted or authorized human activities within .5-miles of winter night roost or communal roost site from November 15th to March 15th if there is a direct line of sight to the activity, .25-mile if there is no direct line of sight. o A Nest survey be performed in each project area (half-mile radius) no later than two weeks before initiating construction for each project location to identify potential raptor nests, perching, foraging areas, and winter roosting areas. o Project construction managers should pause work if nesting or roosting behavior is observed within a .25-mile buffer around the location, followed by communicating with the District Wildlife Manager to discuss alternative plans. o Helicopter activity near identified roosting sites should be avoided from November 15th through March 15th to avoid conflicts with roosting raptor activity. • CPW State Wildlife Area - Garfield Creek SWA: privately owned lands offering wildlife-related recreation to the public, paid for by sportspeople and managed under state law by Colorado Parks and Wildlife for the benefit of wildlife and hosts opportunities for the public to participate in hiking, wildlife viewing, wildlife refugia, and hunting. • Garfield Creek SWA serves as a critical wildlife sanctuary following the big game hunting seasons and when snow levels are high. No work will be authorized on or adjacent to Garfield Creek SWA from December 1st to April 30th. • Garfield Creek SWA is used by hunters throughout big and small game hunting seasons, construction crews should be prepared for early morning and late evening traffic for hunters accessing the area in addition to usual daytime traffic. Protecting large landscapes that support such a wide variety of wildlife species and habitats that they utilize can only be accomplished by partnering with other land users, conservation organizations, and agencies. CPW recommends the following general BMPs that protect wildlife resources. • Submit and follow a robust restoration plan with a wildlife-friendly mix of grasses and shrubs to revegetate disturbed areas. • Any clearing, grubbing, or stockpile materials will be managed to prevent sediment transport and may include seeding with cover crops, tackifier application, or mechanical controls. • Noxious weed control will be required through chemical or mechanical treatment in any disturbed area using a Colorado-certified herbicide applicator. • Any cleared vegetation or topsoil will be treated for noxious weeds and stored outside of the Native Species and Sportfish Management Water Buffer zone and include stormwater control measures. • Notifications to pause or alter work will be at the sole discretion of the CPW District Wildlife Manager or Land Use Specialist and may be short or long-term in nature and will be the result of weather conditions or wildlife movement and other observations. • District Wildlife Managers or Land Use Specialists will assess the situation, the impact, and the duration of the disturbance to develop alternative work plans. • Project construction Managers will discuss upcoming weather events that may impact big game movements, accessibility concerns, or damage to the resources with CPW staff. • Elk, deer, and other wildlife may not be hazed or moved off-site. • Work can resume if the presence of big game is not detected for 24 hours. • Dogs will not be allowed at the Project location. • Trash and debris should be removed daily. • Lighting should be capped from above to help reduce night-sky l ight pollution to avoid interference with nocturnal wildlife behavior. • Conduct work during daylight hours to minimize disturbance to wintering elk, deer, and other wildlife that utilize this area. • The flight path for any helicopter work should be kept within the construction easement corridor to reduce additional disturbance as much as possible. Helicopter work should avoid any wildlife spotted in the area and limit sightseeing diversions. • Remove any mud or debris and disinfect equipment, hand tools, pumps and hoses, boots, and other equipment previously used in a river, stream, lake, pond, or wetland before moving the equipment to another water body following the attached aquatic disinfectant protocols: https://cpw.state.co.us/Documents/Research/Aquatic/pdf/Publications/Quaternary- Ammonia-Compound-Disinfection-Protocols.pdf#search=disinfect Colorado Parks and Wildlife commends the project proponent for minimizing new disturbance, acknowledging wildlife in the area, and incorporating timing stipulations for sensitive wildlife species. CPW appreciates the opportunity to review this project application material and provide recommendations to avoid, minimize, and mitigate adverse impacts on wildlife.

To: Garfield County , Colorado From: Brian Brown – HDR Engineering, Inc. Subject: Reclamation Plan Public Service Company of Colorado (PSCo), a Colorado corporation conducting business as Xcel Energy (Xcel), must replace the existing transmission line between the Mitchell Creek (MITC) to (UTER) Rifle Substations. This line generally crosses rural undeveloped land. T he new poles will be within the existing transmission easement and accessed via existing private or public roads and existing and new access routes . In support of this line rebuild, Xcel has secured two staging/material yards to store equipment, limited equipment assembly, and staff coordination. As the Garfield County permitting will only cover the staging yards, this R evegetation Plan will only address the staging yards. The erosion control and revegetation of the transmission line will be covered and completed per conditions of the State SWMP permit. See the associated maps and figures that are part of the County submittal for locations and improvements to support this Reclamation Plan. Staging Areas Erosion Control and Reclamation Both staging yards, the McLin Yard and the Murray Yard, are similarly designed with the “show up” portion of the yard aggregate covered and the remainder of the yard unaltered. The “show up” portion of the yard is shown on the SWMP submittal as a Stabilized Staging Area (SSA) and contains crew parking, Conex containers, trailers, etc. There are no substantive grading changes to either yard with the only site ‘grading’ limited to removing and stockpiling topsoil to create the aggregate covered SSA. The McLin and Murray s taging areas typically follow the same sequence of impacts and restoration as spelled out below. • Appropriate Xcel, and construction, and erosion control staff will meet on -site immediately prior to the yard construction/use to review the delineated construction impact limits and verify plan meets intended use or is minor adjustments are needed. If the County requires a pre -construction meeting, this would be the time for such to occur. • Xcel erosion control plan developer, Xcel Energy Environmental Analysist, or erosion control install contractor may collect representative topsoil soil samples for analysis in the SSA footprint. This analysis 2 would focus on the potential for possible soil amendments (primarily nitrogen, phosphorus, and potassium) during seeding. 2-3 samples would be typical for the proposed SSA area. • Erosion control measures per the SWMP are implemented in compliance with permit conditions. This typically includes installation of a vehicle tracking control (VTC), limited fencing to prevent impacts to sensitive areas or existing infrastructure , and perimeter Control Measures (CMs) to minimize sediment transport from the project area. • Creation of a Stabilized Staging Area (SSA). An SSA is an aggregate surfaced area that experiences the highest volume of traffic and turning action. The area is stabilized to minimize disturbance, rutting, and sediment track out. o Delineate SSA as shown on SWMP/Grading Plans. o Strip topsoil within SSA. o Stockpile topsoil immediately upgradient of SSA, install down-gradient erosion control measures, and temporarily seed stockpile. o Place aggregate surfacing. • Deliver and arrange equipment, material, Conex, and trailer s, etc. around site. • Beyond the SSA area, traffic of the yard will be primarily for material drop off and material pickup and limited material assembly. Therefore, the yard will remain in the current vegetated state and access and use of the yard will be drive and crush over existing vegetation. This typically leaves the root zone intact and promotes a faster rebound of revegetat ion after demobilization in low traffic areas. • After construction, remaining material, equipment, trailers, Conex, and fencing will be removed from the site along with removal of the SSA aggregate. • Soil decompaction to be performed in compacted areas, primarily in the SSA area. • The SSA topsoil stockpile is to be placed into aggregate stripped SSA area to depths generally matching the pre-construction grades of area. Topsoil will be prepared to accept seed. Note that the presence of rock in the topsoil will generally match the occurrence of rock typical of the yard. • Areas of drive & crush that experienced rutting disturbing may be seeded and mulched. Rutting is defined as greater than 3” depth or when the rut is deeper than the topsoil depth. Determination of where seeding & mulch will occur in rutted areas will be the responsibility of the erosion control inspector or Xcel Environmental Services with the intent of reestablishing area vegetation. • Soil amendments, if recommended in the SSA, are to be added per soil analytic recommendations via mechanical broadcast or hydraulic application. • Site seed mix is to be spread at appropriate rates given application type, hydraulic, drill, or hand broadcast. The amendment and seed application will vary substantially based on disturbance type site access and soil conditions. In cases of hydraulic appli cation, the seed mix may be applied with the liquid amendment or hand broadcast , but in no case is seed to be mixed and applied with mulch. • Seed and mulch, unless agricultural crop land, will be placed per the conditions of the SWMP permit and the County Grading permit. • Final erosion control cover for seeded areas will vary based on access to disturbance areas. Truck or tracked access areas will have either straw crimp mulch (on grades less than 10 percent and low rock content soil) or a high quality hydraulically applied mulch, i.e. Flexterra HP-FGM or like, on grades exceeding 10 percent or high rock content . Xcel Energy generally does not support using erosion control blankets on this project due to concerns about reduced blanket to soil contact and due to longer life blankets having a high synthetic material content with is a wildlife entrapment hazard. 3 • Xcel Energy will change erosion control inspection schedule from weekly to monthly inspections once initial stabilization measures (seeding and mulching) have been completed. If there are areas of concern identified during the monthly inspection that need to be addressed (i.e. erosion or lack of revegetation growth), the revegetation contractor will return to the site to address identified issues. • Per the required State (SWMP) and local (Grading Permits), Xcel Energy will continue to maintain structural erosion control measures across the project until no longer necessary. These will primarily include down-gradient sediment control logs but may include other control measures. These measures will be removed when no longer required and seed will be hand broadcast in areas where removal has created a disturbance and removed/killed vegetation. • Once site has met plant density cover requirements, Xcel Energy will perform a final post -construction site visit to document final conditions and then Xcel Energy will close SWMP permit with the State. • See the Noxious Weed Report for each yard regarding weed management and treatment during the revegetation period. NOTES: • Xcel Energy’s ability to stabilize disturbed areas with vegetation is dependent on many factors within Xcel Energy control. Unfortunately, favorable moisture conditions for germination and continued growth are beyond Xcel Energy control and a key determinate for revegetation. Xcel Energy anticipates adequate revegetation will take multiple years. Xcel Energy frequently returns to sites multiple times that are in the vegetation growth phase to address areas of erosion and reseed and/or mulch as necessary to promote vegetation stabilization. • Xcel Energy hires a separate third-party company to perform the erosion control installation, maintenance, and revegetation as well as another third-party company to perform regular erosion control inspections. These companies have long standing relationships with Xcel Energy. With this approach, Xcel Energy has trained the installation company and inspection company to meet Xcel Energy’s standards and to stay in compliance with state and local permit conditions which improve the restoration trajectory. Xcel’s practice is to continue inspection and maintenance, both performed by third party contractors, until site revegetation is established. Seed Mix: A seed mix with pollinator species is included in the SWMP Report for each individual yard.

Noxious Weed Species Recommended Control Techniques ................................ 8 August 2024 Page 1 Section 1. Introduct ion The Public Service Company of Colorado (PSCo), a Colorado corporation conducting business as Xcel Energy (Xcel), is proposing to rebuild a 25 -mile segment of a 69 -kilovolt (kV) overhead transmission line from the Mitchell Creek Substation to the Ute Rifle Substation on the 6584 Transmission Line (Project). This rebuild is within the City of Glenwood Springs , Town New Castle, City of Rifle, and unincorporated Garfield County, Colorado . Staging areas for the project include the McLin and Murray Yards, which are in unincorporated Garfield County, Colorado. On behalf of Xcel, HDR Engineering, Inc. (HDR) conducted a noxious weed survey for the staging yards. This Noxious Weed Management Plan (Plan) has been prepared to support the installation of prescribed seed mixes, management of noxious weeds, and to comply with federal, state and local requirements regarding noxious weeds in the Project area. 1.1 Project Description The project will utilize multiple staging areas for the overnight storage of equipment and material associated with the transmission line build. All other yards and the transmission line will be permitted separately. The Murray and McLin Yard s are in unincorporated Garfield County and will be associated with the phase 1 build (Appendix A – Project Overview Figure). The McLin and Murray Yards are respectively located southeast and southwest of the town of Silt, Colorado. The 36-acre Murray Yard is located approximately 1 mile west-southwest of the intersection of County Road 3 31 and 346. Access to the yard will be from Chair Bar Road which boarders the north and east perimeter of the staging yard. The McLin Yard is located approximately 0.75 miles southeast of the intersection of County Road 311 and 335. Access to the 15-acre yard McLin Yard will be from County Road 311 . Construction is anticipated to begin in September of 2024 and end January of 202 5. The McLin Yard is located within Section 16 of Township 6 South, Range 92 West and the Murray Yard is located within Section 13 of the same Township and Range of the Public Land Survey System. Section 2. Noxious Weed Management Requirements When present in large numbers, noxious plant species have had considerable impacts to the quality and integrity of natural ecosystems. Noxious weed species can alter fire ecology, successional ecosystem processes, and ecosystem function of the ecosystems they invade. Some species have had such serious economic and biological impacts that their control and management is mandated under Colorado State law (i.e., List A species). Because of the adverse environmental effects of noxious weeds, federal and state governments have issued various orders and regulations regarding noxious weeds. The following are some of the regulations guiding noxious weed management. 2.1 Presidential Executive Order 13112 —Invasive Species Executive Order 13112 , Invasive Species, was issued on February 3, 1999, to prevent the August 2024 Page 2 introduction of invasive species; provide for their control; and minimize the economic, ecological, and human health impacts that result from invasive species. This order directs federal agencies to prevent the introduction of invasive species, control and monitor invasive species, and restore native species and habitats that have been invaded (Federal Register 1999). 2.2 Colorado Noxious Weed Act As defined by the Colorado Department of Agriculture (CDOA), noxious weeds are plants that reduce agricultural productivity, lower real estate values, endanger human health and well -being, and damage scenic values (CDOA 20 24a). The Colorado Noxious Weed Act §§ 35 -5.5-101 through 119, C.R.S. as amended, states that an organized and coordinated effort must be made to stop the spread of noxious weeds. Rules pertaining to administration of the Act include a noxious weed list that designates and classifies noxious weed species into categories for immediate eradication (CDOA 20 24a): • List A contains 24 species of noxious weeds targeted for eradication. If individuals or populations of A List species are found, the local governing body must provide the State Weed Coordinator with mapping that includes information on location and density of the infestatio n. • List B contains 3 5 species that are targeted for eradication, containment, or suppression based upon a given local governing body’s management plan. • List C contains 1 8 species for which the Commissioner of Agriculture, in consultation with the state noxious weed advisory committee, local governments, and other interested parties, will develop and implement into state noxious weed management plans designed to support the efforts of local governing bodies to facilitate more effective integrated weed management on private and public lands. In addition to the three lists, the state maintains a noxious weed species “Watch List”. It contains 19 species that CDOA has determined pose a potential threat to the agricultural productivity and environmental values of the lands of Colorado. It is for advisory and education purposes only and is intended to encourage the collection of information needed to determine if the species should be listed as a noxious weed. 2.3 Garfield County Noxious Weed Management Garfield County adopted a Noxious Weed Management Plan in 2016 to limit the impact of noxious weeds by providing guidelines for managing designated noxious weeds which represent a threat to the continued economic, environmental , and agricultural value of lands in Garfield County (Garfield County 2016). Of the 7 7 plant species considered noxious by the State of Colorado, Garfield County is home to 40 species on this list. The 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. August 2024 Page 3 The intent of the plan is to incorporate th e above-mentioned 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 ensu re that these plants are managed on public and private lands. Garfield County follows the dictates of the CDOAs 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 . Section 3. Noxious Weed Survey Method s On July 24, 2024, HDR conducted pre-construction noxious weed surveys of the Murray and McLin Yard s, hereafter referred to as the study area to document baseline conditions . Noxious weed surveys were conducted using pedestrian transects, with approximately 50-foot separation, covering the entirety of the two staging yards . For the survey, the term “noxious weed ” includes species listed as noxious by the Colorado Department of Agriculture (CDOA 202 4a). Plant nomenclature for noxious weeds in this report follow the CDOA website . Before field surveys were conducted, the following data sources were reviewed for information on vegetation patterns, topography, and hydrology in the project vicinity: • Aerial Imagery – Recent and historic imagery from 1993 through 2019. • Topographic map – U.S. Geological Survey. • General ecological description of the project area (USDA -NRCS 2022). • National Land Cover Database (NLCD) Land Cover (USGS 202 4). • Colorado Department of Transportation (CDOT ) Noxious Weed Map (CDOT 202 4). • Colorado Natural Heritage Program (CNHP) Noxious Weed Inventory, Mapping, and Monitoring (CNHP 20 16). • Colorado Department of Agriculture’s (CDOA) noxious weed list (Effective October 2020) (CDOA 2024a). • CDOA County Weed Programs (CDOA 202 4b). Using ESRI ArcGIS Field Maps field collection software and a sub-foot geographic positioning system (GPS) technology using an EOSTM Arrow 100 antennae and receiver , noxious weed densities were recorded in four categories: 1-10 individuals, 11-100 individuals,101-999 individuals, and 1000+ individuals. Following the field survey, the spatial data of noxious weed species and densities were illustrated in ArcGIS Pro 3.1.2 for the study area. August 2024 Page 4 Section 4. Study Area Description 4.1 Location The Murray Yard is approximately 36 acres in size and the McLin Yard is approximately 15 acres in size. The study area is found within the Silt, CO U.S. Geological Survey 7.5-minute quadrangle (2019). The approximate decimal degree coordinates for the center of the McLin Yard are 39.530407, -107.610966 and for the center of the Murray Yard are 39.525274, -107.679326 (datum is NAD 83). Please refer to Appendix B for a photolog of the study area. 4.2 Topography and Hydrology The study area is in northwestern Colorado and lies within the Western Range and Irrigated Region Land Resource Region (USDA-NRCS 2022) at an elevation of approximately 5,650 feet. The study area is generally located on barren and highly disturbed rangeland and/ or agricultural fields. The McLin Yard is located directly east of a riparian corridor, which contains Divide Creek as well as two irrigation ditches. However, the McLin Yard does not receive any irrigation from these sources as it is approximately 100 feet upslope from them. The Murray Yard appears to drain to the west into an unnamed drainage that flows into a series of irrigation ditches north of County Road 346. Any flow associated with the Divide Creek to the west of the McLin Yard as well as the unnamed drainage to the west of the Murray Yard eventually joins the Colorado River to the north of the study area. 4.3 Land Use Land uses within and around the study area include s agricultural, livestock grazing, rural residential, and industrial uses. Interstate 70, the Town of Silt, and the Colorado River are located immediately north of the study area. There is oil and gas development throughout the surrounding area. 4.4 Climate Annual precipitation in the study area averages 11.6 inches and annual snowfall is 38.5 inches. Rifle records average annual high temperatures of 64.3 degrees Fahrenheit (˚F) and an average low temperature of 31.2 ˚F (Western Regional Climate Center 20 24). 4.5 Vegetation and Habitat The study area is located within dry and disturbed grassland habitat . Both locations appeared to have been chemically treated for noxious weeds in the recent past with visible wilting observed during the July 2024 survey . Additionally, all observed vegetation appeared to be stressed from lack of irrigation and herbivory by dense grasshopper infestations, which made identification difficult. Species that occur within the McLin Yard include prickly lettuce (Lactuca serriola ), field brome (Bromus arvensis), western wheatgrass (Pascopyrum smithii), Canada horseweed (Erigeron cana densis), kochia (Bassia scoparia), crested wheatgrass (Agropyron cristatum ), smooth brome (Bromus inermis), yellow salsify (Tragopogon dubius), and an unknown mustard August 2024 Page 5 (Brassica sp.). Species that occur within the Murray Yard include big sagebrush (Artemisia tridentata), kochia, greasewood (Sarcobatus vermiculatus), prickly pear (Opuntia sp.), needle- and-thread grass (Hesperostipa comata ), winterfat (Ceratoides lanata ), rubber rabbitbrush (Ericameria nauseosa ), western wheatgrass, crested wheatgrass, Russian thistle (Salsola tragus), four -wing saltbush (Atriplex canescens), and an unknown mustard. Please refer to Appendix C for a consolidated list of plant species observed during the field visit. Section 5. Noxious Weed Survey Results Four listed noxious weed species were observed in the study area during the July 2024 survey. Two of the four noxious weed species documented in the study area are on the CDOA’s List B and two are on List C (Table 1 and Figures 2 & 3 in Appendix A). All observed vegetation appeared to be stressed from lack of irrigation and herbivory by dense grasshopper infestations, which made identification difficult. No new growth was observed aside from prickly lettuce (Lactuca serriola) and field bindweed (Convolvulus arvensis), which were observed within the McLin Yard. 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. Noxious weed fact sheets for the four documented listed species are found in Appendix D. Garfield County follows the state’s rules as to which species on Lists A and B must be eradicated, contained , or suppressed and manages those species and the species on its own locally designated list in accordance with the Garfield County Noxious Weed Management Plan (Garfield County 2016). CDOT’s Noxious Weed Map details the locations of List A, B, and C noxious weeds as they occur along the ROW (CDOT 2024). Russian olive (Elaeagnus angustifolia ), hoary cress (Lepidium draba), field bindweed, Russian knapweed (Rhaponticum repens), salt cedar (Tamarix chinensis), musk thistle (Carduus nutans), and Scotch thistle (Onopordum acanthium ) were all documented along the portion of I -70 to the north of the study area. Cheatgrass (Bromus tectorum ) was the most common species identified throughout both Staging Yards. Field bindweed was identified on the east side of the McLin Yard. Small amounts of musk thistle were identified on the northwest side of the Murray Yard. Russian knapweed was identified from the northeast corner down through the center of the Murray Yard . Cheatgrass and field bindweed are designated by the State of Colorado as a List C species and Russian knapweed and musk thistle are List B species. Table 1.

Noxious Weed Management Construction activities would expose soils in areas that have been previously disturbed and limited areas that have not been previously disturbed. This disturbance creates a potential for the introduction and spread of noxious weeds in the project area. Noxious weed species that occur in and adjacent to disturbed areas of the project have the potential to spread into areas impacted by use and construction of access roads for construction equipment and use of staging areas. The goal of this plan is to minimize the spread of noxious weeds due to the proposed project’s construction activities. By implementing measures intended to minimize the spread of noxious weeds during construction and minimizing the establishment of new noxious weed populations post construction, the proposed project should minimize new and help reduce existing noxious weed infestations. Xcel and its contractors work to minimize the use of chemicals that are harmful to beneficial insects in their vegetation management practices controlling shrubs, trees, and weed species within their rights-of -way and properties. This includes eliminating the use of neonicotinoids, a class of neuro -active insecticides, which have been found harmful to all invertebrate populations including bee populations and other native pollinators (Xcel Energy Undated). The study area is adjacent to rural residential developments, rangeland, oil and gas operations, and agricultural fields. Due to adjacent roadways and residential properties in the adjacent areas, noxious weed species are expected to continue spread ing throughout the area. Future construction and maintenance activities by Xcel and its contractors have the potential to expose soils creating a potential for the introduction and spread of noxious weeds in the project area. The grading work will be minimized by limiting the disturbance footprint and focus ing on access grading impacts to the uphill side of access routes. Equipment associated with the project activities that may be stored on the McLin and Murray Yards vary based on the pole type and construction approach. Equipment that may be stored or staged on the McLin and Murray Yards includes construction materials, mini -excavators, pick-up trucks, boom trucks, concrete trucks, and trailer puller reels. Weed management priorities are based on the threat noxious weed species found in the project area pose to the overall goal of maintaining the health of the ecosystem. Generally, List A species are the highest priority because they are often the most aggressive species with limited distribution. No species designated as a “List A” species in the Colorado Noxious Weed Act were August 2024 Page 7 identified. List B species are next priority and List C species are generally widespread and are not prioritized. The best technique for controlling most noxious weeds is an integrated approach of chemical, mechanical, and biological controls. Chemical control involves the application of one or more herbicides at the appropriate time of the year (all herbicides should be applied by a certified applicator according to the manufacturer’s directions). Mechanical control usually involves mowing, hand -pulling, or cutting. Biological control is the use of organisms (usually insects, but also livestock) that are deliberately introduced to an area to control weeds. 6.1 Noxious Weed Treatment Measures As part of the weed management program, the following measure s will be implemented to minimize the spread of noxious weeds during the construction activities, as well as during restoration and reclamation efforts until the closure of the Storm Water Management Plan (SWMP). Xcel’s noxious weed management contractor will implement noxious weed control measures in accordance with existing regulations and local requirements. Post-construction control measures can include one or more of the following methods (that may be implemented during restoration activities): • Treatment methods will be based on species-specific and area-specific conditions (e.g., proximity to water or riparian areas, agricultural areas, and time of year) with the Garfield County coordinator being notified prior to noxious weed eradication activities . If areas are not seeded until the following spring, because of weather or scheduling constraints, undesirable vegetation will be eradicated before seeding. • Mechanical methods rely on equipment that can be used to mow or disc weed populations. If such a method is used in areas to be restored, subsequent seeding will be conducted to re -establish a desirable vegetative cover that will stabilize the soils and slo w the potential re -invasion of noxious weeds. • Discing or other mechanical treatments, that would disturb the soil surface within native habitats, will be avoided in favor of an herbicide application, which is an effective means of reducing the size of noxious weed populations as well as preventing the establishment of new colonies. • Herbicide applications will be controlled to minimize the impacts on the surrounding vegetation. In areas of dense infestation, a broader application will be used and a follow - up seeding program will be implemented. Pre-Construction Prior to construction and soil disturbances, Xcel’s noxious weed contr actor shall apply pre - August 2024 Page 8 treatment, both chemical and mechanical to List A and List B noxious weeds in the areas of expected disturbance which includes staging yards, within expected access road disturbance areas, and any other areas identified in the grading permit as to be disturbed. Chemical and mechanical treatment will be in accordance with the specifics listed in Table 2 and until the SWMP is closed. Post-Construction - Phase 1 At the conclusion of construction (Year 1), disturbed areas will be inspected/surveyed for noxious weeds by a qualified weed specialist. The weed specialist will identify areas where the Control Techniques listed in Table 2 following measures shall be implemented. Post-Construction - Phase 2 Following the growing season after construction has been completed (Year 2) and until the project SWMP permit is closed , two noxious weed surveys shall occur yearly: 1. Early season (May-June) for cool-season noxious weeds (e.g., cheatgrass and bindweed). 2. Late season (July-August) for the warm-season noxious weeds (e.g., thistles and knapweeds). Areas of infestations identified in these surveys will determine appropriate treatment and suppression methods. Table 2 presents species-specific recommended control measures which may be implemented. These recommended control measures are from the Colorado Department of Agriculture website (CDOA 2024a). Some of the noxious weed species are widespread and not found in defined populations, therefore treatment will be difficult and may not be prioritized. Treatment will only occur in areas where soil disturbance due to construction occurred. Due to the knapweed plants being dead and dry during the July 2024 survey, identification should be confirmed based on new growth prior to any treatment measures being impl emented. Table 2. Noxious Weed Species Recommended Control Techniques Common Name Chemical Mechanical Biological Russian knapweed Aminopyralid (Milestone), Aminocyclopyrachlor + Chlorsulfuron (Perspective). Most effective if applied in the fall when above- ground stems die back . Cutting or mowing can stress plant and force it to use reserves. Tilling and disking can create root fragments that can sprout. However, repeated deep tillage (1 feet) over 3 years can kill much of the root system. The gall midge, Jaapiella ivannikovi, is a fly that lays eggs in the shoot tips of Russian knapweed. It forms galls that reduce flowering, seed production, and stunts the plants’ growth. This biocontrol will stress the stand of Russian knapweed but will not likely eliminate it. Not available to public. August 2024 Page 9 Downy brome (cheatgrass) Pseudomonas fluorescens D7 inhibits cheatgrass and is currently approved by EPA and Colorado. Mechanical methods are best for residential areas and small infestations. Collect, bag, and dispose of or destroy flowers; seeds can mature and germinate if left. Tilling must be deeper than 6 inches to work. Prescribed fire applied before seed maturity, (late spring or early summer), may kill seeds; the trick is to get green cheatgrass and litter to carry fire and at a hot enough temperature to destroy seeds and seedlings. No approved biological control agents . Musk thistle Aminopyralid (Milestone), Chlorsulfuron (Telar), and Clopyralid (Transline). Apply in spring from rosette through very early flower growth stages. Methods, such as tilling, hoeing and digging, are best for infestations smaller than 0.5 acres. Sever roots below the soil surface during the first year before the plant stores energy, and in the second year before flower production. Mowing, chopping and d eadheading stimulates more flower production; these methods require consecutive years of season-long treatments. All flower buds and heads must be collected, bagged, and disposed of or destroyed. Prescribed fire that results in high soil burn severity damages roots and above ground biomass, but is not recommended due to impacts on desired plants. Trichosirocalus horridus is the only biological control agent available for musk thistle in Colorado. Field bindweed Clarity + 2,4-D Amine, Tordon 22K *this is a Restricted Use Pesticide, and Roundup Ultra *non- selective herbicide, will kill all vegetation* See Application timing on Noxious Weed Fact Sheets. Cutting, mowing, or pulling has a negligible effect unless the plants are cut below the surface in the early seedling stage. The bindweed gall mite, Aceria mahlerbae, has proven to be effective in reducing field bindweed infestations. Source: Colorado Department of Agriculture (2024a). Table 2 - Control Techniques based on recommendation f rom Garfield County Weed Control Manager, Steve Anthony following the CDOA-published control techniques for noxious weeds . Section 7. Recommended Management and Mitigation Actions In addition to the specific management recommendations listed for each species in Table 2, the following mitigation measures are recommended (as appropriate) to minimize the spread of noxious weeds: August 2024 Page 10 • Construction equipment will remain in designated work areas . • The area of ground disturbance will be kept to the minimum necessary. • Minimize imported topsoil during construction. If importing is necessary, use certified weed-free soil. • Equipment will be thoroughly cleaned before entering the staging area, if equipment or trailer are carrying soil or plant materi al, i.e. mud on trailer undercarriage . • Mulches and straw used at the site will be certified weed -free. • Disturbed areas will be seeded after construction though, if the root structure remains intact, contractor may decide to not seed in such areas. • Seed mixes, soil, and other plant material used for revegetation will be free of noxious weed seeds, roots, and other propagules. • Only a Colorado -licensed Supervisor or Certified Operator will apply herbicides. • Herbicides will be applied in accordance with the manufacturer’s instructions. • Broadcast herbicide spraying will be limited to areas of project ground disturbance and at staging areas. • The Garfield County Vegetation Manager will be notified prior to noxious week treatments, as appropriate to the disturbance jurisdiction. At time of the memorandum, this notification would be through the Garfield County Vegetation Manager (Steve Anthony – 970-945-1377 ext. 4305, santhony@garfield -county.com). • Applicable best management practices (BMPs) from the Stormwater Management Plan will be implemented.

Appendix D. Noxious Weed Fact Sheets List C Key ID Points 1. Downy leaf blades, sheaths, ligules 2. Glumes are unequal size, lemmas are downy 3. One-sided panicle that droops, red-purple during seed set & senescence 4. Fibrous roots C heatgrass (Bromus tectorum L.) is a winter annual grass in the Poaceae family, also known as downy brome. Mature plants reach up to 24 inches tall. The stems are smooth but the leaf blades and sheath are hairy (downy). The ligules are fringed, short and membra- nous. The culms range from five to 90 cm long, can be prostrate or vertical, and have fine short hairs. Its fibrous roots can be up to 60 inches long, but the majority of root biomass is within first 12 inches of the soil surface. Roots are efficient at absorbing soil moisture, allowing cheatgrass to grow quickly early in season, while other plants are still dormant. Green up can occur twice per season. Cheatgrass has an unique spectral signature during seed set and senescence when it turns reddish purple. During these shoulder growing season events, it is easily detectable from other vegetation with satellite imagery. The flower is a simple one-sided panicle that characteristically flops over and hangs, branches and is open. Spikelets are usually terminal. Usually there are five to many florets; it has perfect flow- ers. The upper and lower glumes are usu- ally unequal in length and shorter than florets; the lower glume ranges from 4 to 14 mm in length and is one veined. The upper glume is three-veined. The plant disarticulates above the glumes. The lemmas are usually downy, narrowly lanceolate with sharp tips and about 9 to 12 mm long. Usually there are five to many lemmas. Awns are usually pres- ent and range from 10 to 18 mm long. It is a prolific seed producer, capable of two seed crops per season. Seeds need to be buried in soil or litter and have fall moisture to germinate. The fall seed crop has greater reproductive success than spring. Seeds lack dispersal anatomy so fall close to parent plants but transport readily with animals, people and equip- ment. Seed longevity is about three years. Both inbreeding and cross breed- ing occur. Cheatgrass is one of the most com- petitive non-natives in the Western US. It thrives in arid, semi arid, and cold environments. Colorado’s high eleva- tion range is not an issue for cheatgrass; plants were recently detected as high as 9,500 feet. It exhibits phenotypic plastic- ity and genetic diversity, making it high- ly adaptable to a variety of conditions, likely due to multiple introductions. Its presence has significant negative impacts throughout the West. Most no- tably, it alters fire regimes and thus engineers a posi- tive fire feedback loop that favors its growth over other plants. This feedback loop is why cheatgrass forms monocultures throughout the West. It is often confused with Japanese brome (Bromus ja- ponicus), which has denser more compact spikelets, shorter awns, and changes from green to gold through the growing season.

Maintain robust healthy native landscapes. Restore degraded sites. Avoid soil disturbance. Prevent seed production and seed dispersal, e.g. on contaminated equipment. Rest sites until restored. Modify land use practices. Use methods appropriate for the site, including land use practices. C C Mechanical methods are best for residential areas and small infestations. Mowing and chopping are not recommeded; they leave roots behind, stimulate flower production, disperse seeds, and expand the size of the infested area. Collect, bag, and dispose of or destroy flowers; seeds can mature and germinate if left. Tilling must be deeper than 6 inches to work. Prescribed fire applied before seed maturity, (late spring or early summer), may kill seeds; the trick is to get green cheatgrass and litter to carry fire and at a hot enough temperature to destroy seeds and seedlings. Always combine prescribed fire with cultural methods, timed appropriately, and base it on site conditions and other plants present. Monitoring and adaptive management are critical if prescribed fire is used as a tool for control. C C Pseudomonas fluorescens D7 inhibits cheatgrass and is currently approved by EPA and Colorado. NOTE: Herbicide recommendations to control cheatgrass in pastures and rangeland are found at: https://goo.gl/ TvWnv9. Rates are approximate and based on equipment with an output of 30 gal/acre. Follow the label for exact rates. Consult local turf and ornamental experts for residential settings. Always read, understand, and follow the label directions. The herbicide label is the LAW! B OO C Sheep and cattle will select green cheatgrass which also affects desired cool-season grasses. Properly managed grazing can improve vigor of desired species and directly reduce cheatgrass. Post-fire grazing management varies depending on site potential and objectives. Currently there are no biological control agents for cheatgrass authorized in Colorado. For more biocontrol information, visit the Colorado Department of Agriculture’s Palisade Insectary website at: www.colorado.gov/ag/biocontrol C Biological soil crust is a soil health indicator of arid and semi arid sites; crusts inhibit cheatgrass seed germination. Aerial spread and cultivate soil crust where it is absent. Aerial and drill seeding bluebunch wheatgrass (Pseudoroegneria spicata) and Sandberg bluegrass (Poa secunda) with vesicular-arbuscular mycorrhizae; these are drought tolerant natives that are highly competitive against cheatgrass but require mycorrhizae. As these grasses establish and cheatgrass wanes slowly introduce additional species such as thickspike wheatgrass (Elymus lanceolatus), winterfat (Krascheninnikovia lanata), yarrow (Achillea millefolium) in the plant interspaces in subsequent years. Be cautious when purchasing seed as cheatgrass is often a contaminate, especially in mixes. Use seed pillows to disperse seeds. © Stacy Litz, Associated Press © Bureau of Land Management© Martin Bernetti, Associated Press © Helena Weed Control, Rocky Mountain Elk Foundation White flower © Mary Ellen Harte, Invasive.org.

Flowers are funnel-shaped, white to pink, and have two small bracts one inch below the flower base. 1. 2. Identification and Impacts F ield bindweed (Convolvulus arvensis) is a non-native deep- rooted perennial that reproduces from seed and creeping, horizontal roots (rhizomes). Field bindweed stems are prostrate (grows low to the ground) and twining, and grow up to 6 feet long. Leaves are distinguishable by their arrowhead shape. The flowers are bell or trumpet-shaped, white to pink in color, and are about 1 inch long. Field bindweed seeds can remain viable in the soil for up to 40 years. F ield bindweed emerges from its root system in the spring. Flowering occurs from June to September and until the first fall frost. The number of seeds produced per plant ranges from 25 to 300 and seed production is variable depending on environmental conditions. Field bindweed is an extremely difficult noxious weed to control because, in part, of its taproot that may go 20 feet deep into the soil, and which repeatedly gives rise to numerous long rhizomes. F ield bindweed is a problem throughout Colorado. It is one of the most competitive perennial weeds. It is widespread in cultivated areas, pastures, lawns, gardens, roadsides, and waste areas from 4,000 to 8,000 Key ID Points C o n v u l v u l u s a r v e n s i s Field bindweed Identification and Management feet in elevation. T o successfully manage field bindweed, containment and persistence in controlling existing stands are necessary in order to exhaust the root system and deplete the soil seed bank. This weed needs 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. A healthy cover of desirable perennial plants will assist in discouraging field bindweed establishment. F ield bindweed 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 jursidictions managing this species. O n the back of this sheet are field bindweed management recommendations. For more information, visit www.ag.state. co.us/csd/csdhome.html. Or call the State Weed Coordinator at the Colorado Department of Agriculture, Conservation Services Division, 303- 239-4100. List C Species Rangeland, pasture, and riparian site recommendations List C Species CULTURAL Establishment of selected grasses can be an effective cultural control of field bindweed. Contact your local Natural Resources Conservation Service for seed mix recommendations. Maintain healthy pastures and prevent bare spots caused by overgrazing. Bareground is prime habitat for weed invasions. BIOLOGICAL The bindweed gall mite, Aceria mahlerbae, has proven to be effective in reducing field bindweed infestations. This is an option for large infestations. To obtain a mite release, contact the Colorado Department of Agriculture, 970-464-7916. MECHANICAL Cutting, mowing, or pulling has a negligible effect unless the plants are cut below the surface in the early seedling stage. Well-established populations have a large seed bank in the soil that can remain viable for over 40 years. Bindweed mite damage F i e l d b i n d w e e d Integrated Weed Management: Field bindweed requires active management once it is established because of its potential to regenerate rapidly. Even small infestations should be viewed as a serious threat and managed aggressively. Contain and persistently control infestations in order to exhaust the root system and deplete the soil seed bank. Maintain a healthy cover of perennial plants to discourage field bindweed establishment. ht t p : / / w w w . a g . s t a t e . c o . u s / c s d / c s d h o m e . h t m l HERBICIDES : The following are recommendations for herbicides that can be applied to range and pasturelands.

Wide, stout lance-shaped bracts with spiny tips. M usk thistle Carduus nutans L. is a non-native biennial forb that re- produces solely by seed. During the first year of growth, a rosette forms in spring or fall. During the second year in mid to late spring, the stem bolts, flowers, sets seed, and the plant dies. M usk thistle can grow up to 6 feet tall. The leaves have spines, are waxy, and dark green in color with a prominent light green to white midrib that can be seen from a distance. Leaves are dentately lobed; leaf bases some- times extend down below the point of attachment. The terminal flower heads are purple, large in size (1.5 to 3 inches in diameter) and bend over as if nod- ding. These flower heads are made up of only disk flowers. They are surrounded by numerous, wide and stout lance- shaped, spine-tipped bracts that resem- ble an open pineapple. The pappus has plumose bristles that appear barbed un- der magnification. Musk thistle produces many flower heads. The tallest shoots flower first; lateral shoots develop in leaf axils. A robust plant may produce 100 or more flowering heads. Reproduction is usually via out-crossing through insect pollination, but self-pollination also occurs. Flowers emerge in May through September. Seeds develop shortly after flowers emerge. Flower buds can contain viable seeds from self-pollination. Seeds can mature on severed bud and flower- heads. Seeds remain viable in the soil for up to about 14 years. Seeds can germi- nate and emerge from spring through fall. M usk thistle habitat is found in a variety of environments extend- ing from shortgrass prairie to alpine. It is strongly associated with heavily disturbed sites, where over-use occurs or where site conditions are poor due to land management practices. This includes over-grazed areas, large fires, trails, ditches and roadsides. Infested livestock pasturs suffer from significantly decreased carrying capacity. B ecause musk thistle reproduces solely from seed, the key for suc- cessful management is to prevent seed production. Once flowers emerge and start to produce seed, effective manage- ment options will become limited. Once sites are infested, musk thistle can form dense stands. Prevention, adjusting land management practices, a robust inte- grated treatment plan and restoration are critical to eliminating this species. M usk thistle is designat- ed as a “List B” species in the Colorado Noxious Weed Act. It is required to be eradicated; some popu- lations may be contained or suppressed depending on state regulations.

Distinguished from other knapweeds by the flower’s smooth, papery bracts. 2. Roots are brown to black with scaly appearance. 3. Rosettes and lower leaves deeply lobed. 4. Upper leaves are smaller, smooth margined, and not lobed. Russian knapweed (Acroptilon repens) is a non-native, deep-rooted perennial that spreads by aggressive, creeping, horizontal roots (rhizomes) and seeds. The roots are brown to black with a scaly appearance. Russian knapweed can grow up to 3 feet in height. The stems and leaves are covered with short gray hairs. The ƪǦǡ in color, and are solitary at the tips of the upper branches. Russian knapweed can be distinguished from other knapweeds by the smooth, papery, rounded bracts that surround the ƪǤ in early spring after soil temperatures remain above freezing. It produces ƪ seed in late summer to early fall. The seeds are viable for two to three years. Russian knapweed reproduces primarily from its root system. Buds on the horizontal roots can form adventitious ǡǡ that can grow to become independent plants. Once rosettes emerge in the ǡǦơ until they develop again in late summer. ǡ develop into new plants. Russian knapweed is allelopathic, which means it contains a toxic substance that inhibits the growth of competing plants. This weed may also be toxic to horses resulting in serious injury or possibly death of the animal. Russian knapweed displaces native vegetation and reduces forage values on range and pasturelands. Habitat for Russian knapweed includes roadsides, ditch banks, riparian zones, pastures, rangeland, saline soils, clear cuts, and cropland. It typically invades degraded areas and sites with full sun. Tơ for Russian knapweed is to prevent its establishment through proper land management. Maintain healthy pastures and rangeland and continually monitor your property for new infestations. If Russian knapweed is already established, using an integrated weed management approach proves to ơ Ǥ managed with herbicides or biocontrol insects, but long-term control must include planting competitive plant species to occupy bare ground once infested by the weed. Details on the back of this sheet can help to create a management plan compatible with your site ecology.
