I have noted that this consent is conditional as I have yet to review and concur with the specific application as related to their project, our property and the floodplain of Divide Creek and have yet to execute an agreement with Antero Resources for an "open cut" of our property and specifically Divide Creek. Upon executing an agreement with Antero and reviewing and concurring with the submittal data required with the Floodplain Development Permit Application, if required beyond this consent letter, we will be happy to affix our signature to the application and Statement of Authority. We understand, with this consent, that all application and review fees associated with this permit will be paid for by Antero Resources. Please call with any questions.

The pipeline would be constructed at the intersection of County Roads 311 and 335, sited within Sections 10 and 12, Township 6 South, Range 92 West. Please see Exhibit A - Vicinity Map, and Exhibit C — Site Plan. The original plan was to bore under the intersection of CR 311 and Divide Creek to avoid potential impacts to Divide Creek; however, after the construction crew encountered large rocks and other impenetrable materials it was determined that an open cut ditch across the floodplain would be the appropriate contingency plan. The intent of this plan is to install coffer dams and divert Divide Creek while constructing an open cut ditch to install the proposed pipelines. Once the pipelines are installed and the ditch is completely filled, the landscape will be returned to preconstruction elevations/contours and replanted. This pipeline is not subject to Garfield County Unified Land Use Regulations (ULUR) Article IX: Pipelines. Antero applied for and received two County Grading Permits for this project, one was issued in May and the other was issued in July (both 2010). The total footage of right-of-way for both of these applications is approximately 12,700 feet with 7600 feet in the permit approved in May and 5100 feet in the permit approved in July. A Pipeline Development Plan was not required to accompany the Grading Permits according to the Garfield County U R because the pipe diameters are not greater than 12 inches nor is the total length in excel of 5 iies. rr oated West Water Engineering has performed wetland delineation and requested a Nationwide permit from the US Army Corp of Engineers. (Please refer to attached documentation) The pipelines will be buried a minimum of five (5) feet and protected from flood damage. Special specifications for construction in the floodplain are not applicable, and the water course will not be altered. The cumulative effect of this proposed development, when combined with all other existing and anticipated development will not increase the water surface elevation of the base flood more than one foot at any point. The proposed pipelines will be buried and Divide Creek will be restored to its current cross section, resulting in no increases to the base flood elevation and no impacts to the floodway. There will be no change in the flood -carrying capacity of Divide Creek. As the pipelines will be buried, no danger to the public is posed. 826 211/2 Road TEL 970.263.7800 Grand Junction, CO 81505 FAX 970.263.7456 www.oaconsulting.com Variance Requests (2) 1. Floodplain Overlay: Floodway Analysis. The Federal Emergency Management Agency (FEMA) has designated the Divide Creek floodplain as Zone A, an approximate floodplain with no base flood elevations. An effective floodplain model does not exist and a floodway had not been identified by FEMA. The proposed pipes will be buried and the land use will not change. A variance from this requirement is requested. 2. Floodplain Overlay: Floodplain Impact Report. For the reasons stated in the preceding section, a variance from this requirement is requested.

Dear Mr. Morse:. Antero Resources requested WestWater to perform a wetland delineation and Nationwide Permit (NWP) #12, Utility Lines Activities, for review and verification for an open cut ditch crossing of Divide Creek in Silt, CO. Antero Resources had intended to horizontal directionally drill (HDD) under Divide Creek at the intersection of CR 311 and CR 335. The intention of the bore was to eliminate potential impacts to wetlands adjacent to and including Divide Creek. During the boring process Antero encountered Targe boulders embedded in a sandy substrate. As the boring continued, significant difficulties were encountered when the boulders rolled in the Ioose substrate. This resulted in a crimped bore and Antero abandoned boring operations. To facilitate completion of the project, Antero would like to implement their contingency which is to cross Divide Creek and adjacent wetlands with an open cut ditch. WestWater conducted a thorough evaluation of the project area and delineated wetlands within the project area. This letter and pre -construction notification is a request to fulfill requirements for NWP #12. Pertinent information concerning this request follows. Please feel free to contact our office if you have any questions regarding this delineation, or if we can be of assistance in any way. Sincerely, Brett F. Fletcher Environmental Scientist/ Wetland Biologist Wetland Delineation Divide Creek Prepared for: Antero Resources Prepared by: WestWater Engineering August 2010 Introduction WestWater Engineering (WWF) biologists were requested to perform a wetland delineation and file a pre -construction notification (PCN) for a Nationwide Pertnit (NWP) #12 verification request. Pertinent information concerning this request follows: Applicant: Antero Resources, Jerry Alberts, Environmental Regulatory Manager, 1625 17th Street, suite 300, Denver, CO. 80202 Property Owners: Parcel number: 2179-123-00339, Simonson, Jefferey & Brenda, 2045 County Road 311, New Castle, CO. 81647-9617. Parcel number: 2179-114-00114, Dixon Water Foundation, 6060 N. Central Expressway, Suite 305, Dallas, TX. 75206. Property Location: Section 10 & 12, T6S, R92W Project can be accessed by taken I-70 east to the Silt exit and turning south crossing over the Colorado River. Once you are over the river, turn east on the CR 335 (Colorado River Road) and follow for it approximately 1.25 miles to the intersection of CR 311 (Divide Creek Road). The project is located at this intersection. Total Project Site Acreage: Approximately 1.5 acres. Background Antero Resources had intended to horizontal directionally drill (HDD) under Divide Creek at the intersection of CR 311 and CR 335 (Figure 1). Antero Resources had intended to horizontal directionally drill (HDD) under Divide Creek at the intersection of CR 311 and CR 335. The intention of the bore was to eliminate potential impacts to wetlands adjacent to and including Divide Creek. During the boring process Antero encountered large boulders embedded in a sandy substrate. As the boring continued, significant difficulties were encountered when the boulders rolled in the loose substrate. This resulted in a crimped bore and Antero abandoned boring operations. To facilitate completion of the project, Antero would like to implement their contingency which is to cross Divide Creek and adjacent wetlands with an open cut ditch. Delineation Methods — WestWater biologists performed a wetland delineation of the project area on August 19, 2010. The wetland boundaries were identified on the basis of the vegetation, soils, and hydrologic characteristics present at the site in accordance with the Arid West Regional supplement to the Army Corps of Engineers (COE) Wetland Delineation Manual, September 2008. The wetland boundary delineation included identification of plant species, vegetation composition, and structure. Soil borings (18 ± in. deep) were taken with an auger for observation of wetland soil and hydrology indicators within the potential wetland. Wetland boundaries were marked using orange flags.

Adjacent wetlands appeared to have a source of hydrology independent of Divide Creek. It appears that hydrology to these wetlands is supplied by groundwater seepage from the irrigated pastures on the mesa west of the project area. Flags were placed along wetland boundaries, boundary line A and B, at their transition to uplands. Boundary line D indicates a dry island that is surrounded by wetlands in the project area. Data sheets were completed for wetland to upland transects near flags A06, A18, and B04 (Figure 2) and are attached to the end of this report. Proposed Construction and Impacts - It is Antero Resources intent to install coffer dams and divert flows through a corrugated metal pipe (CMP) while constructing the open cut ditch (OCD) through Divide Creek. Once the ditch has been backfilled and preconstruction contours have been reestablished, flow will be returned to the natural channel and the CMP will be removed. Antero estimates that the project will be completed within 2 weeks of commencement. Re -contouring and re - vegetation operations will also be completed in that time frame. Temporal impacts through the stream channel and adjacent wetlands are negligible considering the amount of time it will take to cut the ditch, lay pipe, back fill, and reestablish wetland vegetation. "There will be no permanent impacts to WoUS or adjacent wetlands. Disturbance will be limited to 25 feet on either side of the centerline of the ditch (Figure 2). The ditch will be dug 5 feet deep and 3 pipelines will be installed. There will he a 12 inch water line in a 16 inch casing, a 12 inch steel gas line, and an irrigation water line (see attached Drawings). Top soil and vegetation will be removed and set aside until ditch work has been completed. Vegetation and top soil will be distributed once the ditch has been filled and the area returned to its pre-existing topography. No Woi7S will be depleted or impounded during OCD construction. It is WestWater's assertion that a "no significant impact" finding is warranted for temporally impacted WoUS. Antero Resources will submit before and after photos to the COE for the stream and wetland remediation once it has been co€nplctcd. Threaten and Endangered Species Based on a review of federally listed species in Garfield County, on the US Fish and Wildlife Service website, it is likely the proposed project will have no effect on threatened or endangered species habitat. Table 2 contains the federally listed species in Garfield County. Table 2. Garfield County Threatened and Endangered Species Common Name Scientific Name Status Bonytai[ Gila elegans Endangered Canada lynx Lynx Canadensis Threatened Colorado pikeminnow Ptychocheilus lucius Endangered Humpback chub Gila cypha Endangered Mexican spotted Owl Strix occidentalis lueida Threatened Razorback sucker Xyrauchen texanus Endangered Uinta Basin hookless cactus Sclerocactus glaucus Threatened Ute ladies' -tress orchid Spiranthes diduvaialis Threatened The northern boundary for critical habitat for listed species in the Colorado River, Razorback sucker and the Colorado pikeminnow, is exit 90 (Rifle exit) north off Interstate 70. The confluence of Divide Creek and the Colorado River is approximately 8 miles upstream of the end of critical habitat. There is no other critical habitat within 10 miles of the project area, A web search was conducted on the National Register of Historic Places web site, www.colohistory- oahp.org, and no results were found in the project vicinity. There are no buildings or structures in the project area nor does the project area appear to meet any of the evaluation criteria for nomination to the National Register of l listoric Places as listed in 36 CFR 60.4.

The pipelines will support Antero Resources ongoing natural gas production in the area. The project is located across four parcels listed below: Dixon Water Foundation Simonson Regulski McLin, Brit C. & Sharon T. Parcel No. 2179-114-00-114 Parcel No. 2179-123-00-339 Parcel No. 2179-123-00-295 Parcel No. 2179-131-00-554 Antero proposes to install a 12" steel gas gathering line and two 12" poly water lines between the Valley Farms K Pad and the McLin A Pad. The proposed Right -of -Way is approximately 5,100 feet in length and 50 feet in width during the construction process. The estimated area of disturbance is 255,000 sq. ft. or approximately 5.85 acres. The pipelines will be installed in the same ditch (6 ft. width) with a minimum cover of 48 inches (5 ft. depth). The anticipated dirt volume moved is approximately 5,700 cu. yd. The existing topography will be maintained after the pipelines are installed so no change in drainage pattern is expected. Vicinity Map — see attached maps Site Plan/Pipeline Route — see attached by River Valley Survey Letter of Authority — see attached copies of existing easements with the three landowners the pipeline will be crossing. Erosion Control Plan and Details —Erosion prevention best management practices (BMPs) will be implemented and maintained in accordance with Antero's approved Stormwater Management Plan dated August 2009 (attached). The BMP's described in the Plan will be utilized and inspected as necessaay during the course of construction and revegetation of the ROW. The expected locations of the BMP's are shown on the Site Plan as indicated and the site plan supporting project maps are included in the most recent version of the company's S WMP. Major Grading Permit This permit application is considered a Major Grading Permit category due to the square feet disturbed (approximately 255,000 square feet). i) Revegetation and Reclamation Plan — see attached ii) Financial Security --- Antero will provide a letter of credit or bond upon Garfield County's request, if required. Based on Garfield County's recommendation (Section 4 of the Weed Management and Reclamation Plan) of $2500 per acre, it is estimated the reclamation cost is $15,000. iii} Plans have been stamped by Professional Engineer Registered in Colorado — not required for pipeline excavations of this nature. Pipeline Project Although not required, the Site Plan does include some topographic contours in the area. The final grade after the pipeline installation will be the same as the existing grade prior to installation. Approved State Stormwater Management Plan — The most recent version of Antero's SWMP is attached for your review. Soils Report Not required as the maximum depth is less than 15 feet (actual anticipated depth is 5 feet) and the native slopes are less than 25%. Drainage Report Final grading is not anticipated to change the native drainage patterns. The existing drainage patterns will be maintained after the proposed pipeline installation. Grading Permit Fee — see enclosed check from Antero Resources in the amount of $400.00 and made out to the Garfield County Treasurer. Weed Management and Reclamation Plan Section 1—Soil Handling The proposed pipeline extension will disturb approximately 255,000 square feet (or approximately 5.85 acres) of surface during the construction process. This is based on a 50 foot wide Right -of -Way (ROW) along the 5,100 pipeline length. The actual volume of soil moved is based on a 5 foot deep pipeline trench that is 5 feet wide over the same length and totals approximately 5,700 cubic yards. Top soil will be scraped off first and stored in a separate spoil pile along the ROW for replacement once the final grade is restored after construction. The entire pipeline project should be completed in approximately 45 days once construction begins. Construction is anticipated to begin in late -July and be completed by early August, 2010. Erosion control will be in accordance with Antero's State approved Stormwater Pollution Prevention Plan (see attached) and the appropriate SMP's will be utilized along the ROW as needed. Weed -free straw will be utilized where straw bales or straw waddles are indicated for erosion prevention/control. Dust suppression will be handled by a water truck along the ROW on an as needed basis. Section 2 — Weed Management Plan Antero has obtained the latest County Listed Noxious Weeds from the Garfield County Vegetation Management Department and has included that in the application. Section 2.1 — General Survey Information Field inspections of the project area will be conducted by WestWater Engineering (WWE) biologists in the spring during the commencement of the weed growing season. WWE biologists will survey the area in and around the proposed pipeline project to identify vegetation communities and to starch for, identify, and map noxious weed species. Vegetation types will be determined through field identification of plants, aerial photography, and on -the -ground assessment of plant abundance visible during the survey. Identification of plant species will be aided by using pertinent published field guides (Whitson et al. 2001, CWMA 2007, Kershaw et al. 1998, Weber and Wittmann 2001). Photographs will be taken of the general project location, vegetation, terrain, and other specific biological findings. Locations of weeds and other features to be included in this survey report will be recorded with the aid of a handheld global positioning system (GPS) receiver using NAD831WGS84 map datum, with all coordinate locations based on the Universal Transverse Mercator (UTM) coordinate system in Zone 13. Since the construction is proposed for the winter, Antero is not planning to pre -treat the ROW prior to commencing construction. In March, when the construction phase of the project is complete, Antero will seed the ROW prior to the growing season and on a monthly basis until the native/reseeding has taken hold of the disturbed ground. In addition, the weed treatment program will commence in the spring at the beginning of the weed growing season and after the weed survey has been completed. The weed treatment program consists of at least two treatments per year to address annual and perennial weed species. The treatment programs will be conducted in accordance to the recommendations presented in the weed survey report. The ROW will be inspected every two weeks after completion of construction to insure reseeding is effective and the weed control is working. The weed treatment program and reseeding efforts will enhance in response to the findings of these inspections. Section 3 — Site Revegetatian and Reclamation Reseeding of the ROW will occur in the late-April/early-May timeframe depending on the weather conditions at the time. Antero will reseed the native ground with the seed mixtures listed below utilizing a tractor mounted delivery system. A portion of the ROW is on agricultural land and that section of the ROW will be reseeded with the appropriate crop as requested by the landowner. Antero proposes to use the following seed mix: Dry Land Mix Pure % Germ% Origin Crested Wheatgrass, Hyerest 19.58% 94% CAN Smooth Srome, Lincoln 18.17% 95% KS Perennial Ryegrass VNS 14.99% 90% OR Stender Wheatgrass, Revenue 14.62% 96% CAN Orchard grass, Renegade 14.37% 90% OR Tetraploid Intermediate Wheatgrass, Oahe 9.64% 94% WA Dahurian Wildrye, VNS 4.96% 98% CAN irrigated Land Mix Orchard grass, Potomac 32.0% 90% OR Tall Rescue, Rustler 22.55% 92% OR Tetraploid Perennial Rye grass, Verano 19.51% 90% UK Smooth Srome, Lincoln 13.17% 95% KS Plant hydration, if inadequate through natural means, will be provided by tractor/truck mounted sprayers on an as needed basis until adequate re -vegetation has been established. Due to the gentle slope of the ground along the entire ROW, it is not expected that mulch or juke mats will be required to hold vegetation/seeds in place during the revegetation process. Ha particular area warrants one of these stabilization methods, it will be utilized as needed. Interim and final reclamation measures shall be consistent with those outlined hi the Colorado Oil and Gas Conservation Commission's (COGCC) amended rules, effective April 1, 2009 (COGCC 2009). These regulations are expected to fulfill Garfield County's requirements for interim and final reclamation standards. Section 4 — Cost Estimate Since the proposed project is a pipeline project and the post -project grade will be restored to the pre -project grade Antero has used the County recommended $2500/acre to estimate the cost. Based on 6 total acres disturbed, the cost estimate is $15,000.

Date 1 2.0 INTRODUCTION CTION On June 30, 2005, the State of Colorado stormwater regulation went into effect to require Colorado Discharge Permit System (CDPS) permits from the Colorado Department of Public Health and Environment (CDPHE) Water Quality Control Division (WQCD) for stormwater discharges from construction activities associated with small construction activity for oil and gas sites that disturb between one and five acres. The Stormwater Management Plan (SWMP) was prepared for Antero Resources (Antero) to be used for the Piceance Basin Gravel Trend Midstream Pipeline Program in accordance with good engineering, hydrologic, and pollution control practices to ensure that Best Management Practices (BMPs) are selected, installed, implemented, and maintained to protect surface water. This document contains the required elements of a SWMP associated with Antero's construction activities for the Project, as defined in the CDPS General Permit for Stormwater Discharges Associated with Construction Activity, Authorization to Discharge Under the Colorado Discharge Permit System (Permit No. COR -030000, re -issued and effective July 1, 2007). Antero applied for coverage under the stormwater general permit and was issued COR -038500 for the Piceance Basin Gravel Trend Midstream Pipeline Program Area on July 5, 2005, The application and permit number were renewed at the re -issuance of the general permit. A copy of the permit documents for this project is provided in Appendix A. 3.0 SWMP ADMINISTRATOR The SWMP Administrator for Antero is responsible for the developing, implementing, maintaining, and revising the SWMP. The SWMP Administrator has the authority to dedicate the financial and human resources to implement the SWMP. The SWMP Administrator is: Mr. Gerard G. Alberts --- Manager, Environmental & Regulatory, Denver, Colorado Office: (303) 357-7341 Mobile: (720) 201-0160 The SWMP Administrator will ensure that the SWMP is followed and delegates responsibility for coordination of the SMWP inspections and maintenance of stormwater records to the Operations Manager, The Operations Manager will provide support for the SWMP Administrator with the implementation of the SWMP.

Overall, the SWMP Team is responsible for: 2 (0'7 • Implementing spill/upset clean up procedures; • Notification to local authorities and local residents of reportable releases; • Coordinating various stages of BMPs and implementation; • Conducting inspections; • Maintenance of all records; and • Coordination of a preventive maintenance program and housekeeping measures. 4.0 SITE DESCRIPTION 4.1 Nature of Construction Activity Antero is an exploration and production (E&P) company focused on acquiring and developing unconventional natural gas resources in North America. Antero currently owns or leases oil and natural gas mineral rights in the Piceance Basin, Garfield County, Colorado. Antero's Piceance Basin Gravel Trend Midstream Pipeline Program Area lies within Township 6 South, and Ranges 92 West and 93 West. The pipelines consist of an area approximately eighty feet in width known as a right-of-way (ROW). These RDW's can extend for several miles covering a multitude of surface land uses. A topographic map of the project area is provided as Figure L 4.2 Sequence of Major Activities The overall development of oil and natural gas pipeline is generally accomplished in a single phase of construction. The work completed and sequences of events are briefly discussed below. The pipeline installation contractor will adhere to the following sequence of operations unless otherwise approved or directed by Antero or the Bureau of Land Management's (BLM's) engineer/compliance officer. Revision to this sequence may be instituted if approved by the state engineer/compliance officer, in consultation with the BLM Authorized Officer (AO), if such modifications do not result in erosion or sedimentation at the site. Further control measures may be required by the project engineer or the BLM AO in special circumstances. Pipelines connect pad sites to other gathering operations within the basin. Pipeline connections are regularly maintained, added to, or repaired. The development of underground gas pipelines is generally accomplished in three distinct work phases. The first phase is the development (construction/completion/reclamation), and the second phase is the abandonment with final reclamation. Each work phase is briefly discussed below. 4.2,1 Development (Construction/Completion/Reclamation) -- Active Site The development phase includes the following activities: develop access; install vehicle tracking control; install silt fence around stabilized staging areas; install silt fence and or berms on the down gradient limit of construction for erosion and sediment control; and install straw bales 3 STATE OF COLORADO Rill Ritter, Jr.,.Gavernar James B.

Malin, Regulski, Simonson REPRESENTATIVE: Lorne Prescott, David Krickbaum-Olsen Associates PRACTICAL LOCATION: Intersection of CR 311 and 335 TYPE OF APPLICATION: Flood Plain Development GENERAL PROJECT DESCRIPTION — On September 23, 2010, staff met with representatives from Olsen Associates to discuss the Floodplain development permitting process and review. The proposal is to install gas and water pipelines within the floodplain of Divide Creek. Because the lines were less than 12" in diameter and less than 5 miles in length the pipeline had been allowed under a county grading permit. The original plan was to bore under the intersection of CR 311 and Divide Creek to avoid potential impacts to Divide Creek; however, after the construction crew encountered large rocks and other impenetrable materials it was determined that an open cut ditch across the floodplain would be the appropriate contingency plan. The intent of this plan is to install coffer damns and divert Divide Creek while constructing the open cut ditch. Once the ditch is completed, the landscape will be returned to preconstruction elevationslcontours and replanted. West Water Engineering has performed wetland delineation and requested a Nationwide permit from the US Army Corp of Engineers. A review of Garfield County's flood plain maps show that this portion of Divide Creek is within the 100 year flood plain and will require a flood plain development permit from the county. Please be aware, that as long as there are legal or code enforcement issues with the pipeline crossing the Regulski property the county will not issue any land use permits for this application.

Generally, no legally binding controls are imposed on land use. Purchase of Development Rights. Purchase of the right to develop from owners of specific parcels, leaving the owner all rights of ownership. The price of the rights is the diminution in the market value of the land as a result of the removal of the development rights. The remaining value of the land is the "farm use" value. Purchase and Resale or Lease with Restrictions. Purchase of land, imposition of restrictions on use and development and resale at market price. End result is equivalent to purchase of development rights. Transfer of Development Rights. Development rights on land in a designated preservation area may be purchased by a developer and transferred to a designated development area where the equivalent amount of additional development can be constructed. Differential Assessment. Assessment for property tax purposes based on the farm use value of the land rather than the market value. There are three major types of differential assessment: pure preferential assessment with full abatement; deferred taxation with partial or with no abatement; and restrictive agreement, under which a farmland owner contracts to maintain his land in farm uses in return for a lower assessment. Development Permit System. Requirement that a special permit be obtained for development from a designated state or regional agency. Permit is in addition to normal local zoning and building permits. Right to Farm. Legislation stating that local ordinances cannot be enacted which restrict normal farming practices unless they endanger public health and safety, and providing farmers with some protection against private nuisance lawsuits. Table 29 classifies these programs and approaches by general purpose and type. 9.9 Conclusions • Although agricultural uses account for less than 2 percent of total County income and employ less than 6 percent of County residents, the tradition of ranching and farming in the County is an important cultural component. Furthermore, although its economic impact is weakening, agricultural uses still occupied approximately 25 percent of the total land area in Garfield County in 1987. • Agricultural land in the County, particularly those uses designated as "Prime Farmland" by the Soil Conservation Service, is predominantly located on the Valley floors, and is generally flat with little topographical constraints to development. These characteristics will continue to encourage the Table 29 Common Programs to Protect Agricultural Lands General Purpose of Program Type of Program Land Use Programs 1 Tax Incentive Programs Reduce Relative Attractiveness of Farming Area For Development Offset Additional Burden on Farming Caused by Urbanization Comprehensive Planning Agricultural Districting Prohibition of Local Nuisance Ordinances Capital Gains Tax .r• Right to Farm Legislation Prevent Changes in Land Use Restrictive Agreements Agricultural Zoning Development of Permit Systems Purchase of Development Rights Purchase and Resale of Restrictions Transfer of Development Rights Source.

The historical and cultural importance of farming and ranching, particularly in the western portion of the County; 2, The trend towards development in historical agricultural lands will continue to intensify, 3. The transitioning of the County from ranching and farming dependence to a more service and tourism - based economic base. 10.0 ENVIRONMENTAL CONSTRAINTS Garfield County is composed of a wide variety of topography, climate, vegetation, and natural features. These characteristics make development challenging depending on the exact location and scope of the proposal. Furthermore, due to the sensitive nature of many parts of the County, decision makers and Planning Staff need to be cognizant of the unique aspects of specific areas of the County. In areas where development may damage or destroy important natural resources, appropriate mitigation or design components must be implemented. This section of the Plan describes areas that warrant concern, suggests available resources to assist in identifying areas of critical concern and developing policies to address the unique environment that compose the County. The following discussion addresses areas of particular concern, the status and availability of general planning information, an analysis of existing Comprehensive Plan objectives and policies and concludes with suggested policy changes to address these issues. 10.2 Ecologically Critical Areas These areas contain one or more significant natural resource that could be degraded or lost as a result of uncontrolled or incompatible development. They are based on resource quality, scarcity or the role the resource plays in the ecosystem. These areas can provide many amenities and services to the public and to private landowners. Riparian and Wetlands. Wetlands are widely recognized as important components of the ecosystem and provide a wide variety of benefits including flood control, water purification and fish and wildlife habitat. Wetlands also support approximately 30 percent of federally protected and endangered species. Simply stated, the filling or destruction of wetlands during construction contributes to downstream flooding, declining water quality and diminished fish and wildlife habitat. The regulation of impacts on Riparian and Wetlands fall within the jurisdiction of the Army Corps of Engineers, with statutory authority based on the enforcement of Section 404 of the Clean Water Act, as amended. Section 404 of the Clean Water Act requires approval prior to discharging, dredging or placing fill material into the waters of the United States. Typical activities requiring Section 404 permits are: • Depositing of fill or dredged material in waters of the U.S. or adjacent wetlands; • Site development fills for residential, commercial or recreational developments; • Construction of revetments, groins, breakwaters, levees, dams, dikes or weirs; • Placement of riprap and road fills. Local policies can assist in the protection of these areas through the implementation of Zoning, Subdivision and PUD policies. For example, it is clearly within the jurisdiction of the County to require minimal disturbance to wetlands and riparian areas, prohibit the removal of vegetation, require re -vegetation, the maintenance of baseline biological conditions and the enforcement of specific structural setbacks from stream banks and riparian areas. Wildlife Habitat. The Division of Wildlife (DOW) has developed a series of maps that describe the Winter Range, Winter Concentration Areas, Severe Winter Range, Highway Crossings, Migration Corridors, Migration Patterns, Production Areas, Summer Range and Critical Habitat for Elk, Mule Deer, Pronghorn, and Bighorn Sheep. The Division of Wildlife is available to assist local governments in developing "Wildlife Habitat Composite Maps". These maps are produced by stacking the 20 or so individual species maps and calculating the cumulative value of overlap areas. Personnel from the Division review the composite information and evaluate the potential for low, moderate, or high impact to wildlife habitat based on these maps. To assist in the evaluation of wildlife impacts, a worksheet has been applied elsewhere to integrate these maps in the planning process. The worksheet provides the planner and project proponent a direct cause and effect perspective on the impacts of a proposed project. The worksheet is also an effective method to initiate contact between planners, proponents and CDOW personnel in order to discuss potential impacts and alternative approaches to lessen or eliminate these impacts. The use of DOW maps and data varies among counties. Some counties have included guidelines in their land use ordinances to suggest how wildlife impacts may be dealt with. The review of CDOW maps is an official and formal procedure required for proposed projects. In other cases, it may consist of an informal review by planning staff. Official actions are preferred, as they furnish a consistent method of evaluating wildlife impacts regardless of changes in CDOW and county personnel, 10.3 Natural Hazard Areas Geological Hazard Area. Geologic hazard areas are defined as those areas characterized by earthquake faults, a high frequency of landslides, subsidence or severe erosion, In 1976, the County contracted with The Lincoln-Devore Testing Laboratory to produce a series of maps to identify and classify, on a broad scale, the geologic hazards within the County. These studies were intended to identify areas that may warrant further study or mitigation, depending on the specific development proposal in the area. These maps provide The Board of County Commissioners, the Planning Commission and planning staff a valuable method for determining the appropriateness and possible mitigation necessary to address geologic constraints for individual development proposals. The information contained in the study is currently under-utilized by planning staff. The specific information that these maps contain, is found among the Land Use Mapping included within the Comprehensive Plan, available for public viewing, includes the following data sets: Surficial Geology 1. Landslides, including all types of slope failures other than mudflows; 2. Mudflows; 3. Fans, showing areas of past and present debris fan activity; 4. Torrential Wash Fans; Slope Stability 1. Potentially Unstable Slopes; 2. Unstable Slopes; 3. Debris Slides; 4. Mudflows; 5. Rockfalls; 6. Talus Slopes; 7. Debris Fans; 8. Active Slope Failure; Soils Hazards 1. Corrosive Soils; 2. Expansive Soils; 3. Highly Expansive Soils; 4. Potential Subsidence; 5. Active Subsidence; Scope Hazard Areas AREA 1 Areas of minor hazard, such as soil creep, potentially unstable slope or area of safety zone surrounding serious hazards. Further investigation should include a detailed geologic study, followed by engineering analysis if geologic study disclosed a problem. Mitigation for these hazards is generally described as simple and economical. AREA 2 These areas should include a detailed geologic investigation and engineering study, including test drilling, simple strength tests, groundwater evaluation and stability analysis. Mitigation for these hazards is usually possible, but will often be expensive and may involve large-scale construction work. Special siting may be helpful. AREA 3 Areas of Major Hazards, such as active landslides. Investigation for these areas should Include geologic study, intensive drilling and strength testing, stability analysis and monitoring of soil, rock and groundwater conditions. Mitigation may be possible in these areas, but could be quite expensive, require special siting and involve a certain element of risk. Soil Hazard Areas AREA 1 Areas of rninor, easily mitigated hazards, such as expansive or corrosive soils. Investigation should include geologic study, limited sampling and soil testing. Mitigation typically involves design modification or use of special materials. AREA 2 Areas of moderate hazards, such as subsidence hazards. Investigation includes detailed geologic study, test drilling and analysis. Mitigation usually involves special siting and design. AREA 3 Areas of major hazard, such as outcrops of corrosive, subsiding or evaporite rock. investigation includes detailed geologic study, test drilling and chemical testing and other professional analysis. Mitigation involves special siting, design and use limitations; the Lincoln-Devore Study recommended that development of these areas be avoided, if possible. SCS Soil Surveys. Soil surveys, produced by the Soil Conservation Service, are a detailed inventory and evaluation of the specific soil types within a region. The County has a copy of these detailed maps on file at 1:24,000 (1" = 2000') scale. For general planning purposes, the SCS provides a general soil map, which is shown on Map 11. The general soil map provides a broad perspective of the soils and landscape of the County. It provides a basis for comparing the potential of large areas for general kinds of land use. Because of its small scale, the map does not show the kind of soil at a specific site. Therefore, it is not suitable for selecting specific land uses or identifying mitigation measures appropriate for individual development projects. The detailed soil maps, which have recently been updated by SCS on 1:24,000 scale U.S.G.S. quadrangle maps, are appropriate for this level of analysis. Floodprone Areas. These areas are identified on the basis of the frequency and potential for flooding. The County uses the Flood Insurance Rate Maps developed by the Federal Emergency Management Agency (FEMA) to determine the various rate zones of the 100 -year floodplain boundaries within the County. Due to the scale necessary for assessing specific floodplain hazards, these maps are retained in the Planning Department and are available for review by the public during normal business hours. The County has digitized FEMA maps for Study Areas 1, 11, and 111, and these are included in the mapping in Section V. Fire Hazard Areas. The continued dispersal of residential uses in undeveloped portions of the County increases the likelihood of catastrophic property loss due to wildfires. The Colorado State Forest Service, the agency responsible for reviewing and commenting on the wildfire hazards in the County, describes this process of urbanization as the "wildlandlurban interface." Wildland refers to all hillsides, valleys, prairies and forests. The natural vegetation in these wildlands may be pines, hardwoods, tall grasses, chaparral or other varieties of vegetation. The urban part of the interface terminology describes all of the manmade structures that accompany the homes, such as storage sheds, commercial buildings, schools, churches and recreational structures. The "interface" in Garfield County can be classified into two general types: • The Mixed Interface contains individual structures scattered throughout rural areas. Usually these are isolated homes surrounded by larger or smaller areas of land. When a fire starts, the individual homes are difficult to protect because of the large area that may be burning, but there may be relatively few homes at risk. • A Classic Interface is where homes, especially those crowded onto smaller lots in new subdivisions, press against the wildland vegetation along a broad front or fronts. Vast adjacent wildland areas can propagate a massive flame front during a wildfire, and numerous homes are put at risk by a single fire. A potentially massive property loss can occur due to the high density of these developments. The Colorado State Forest Service is available to review and suggest mitigational measures for specific projects that are susceptible to wildfire. The Forest Service has adopted a series of mitigation measures. These measures should be enforced by the Board of County Commissioners, the Planning Commission and planning staff during the project review and approval process. 1, Location of Building Site. The Forest Service recommends that building envelopes be located on the most level site possible. For instance, during a fire, narrow canyons become natural chimneys drawing fire and accelerating its rate of spread, if a home is placed on a ridge, the Forest Service recommends a setback of at least 30 feet for a single family home, to prevent the house from being hit directly by flames and heat moving up the sides of the ridge. 2. Emergency Access. In the event of a fire, firefighting equipment must be able to quickly access a site, while at the same time, occupants may be evacuating the homesites. This situation, combined with smoke and soot from a fire, could lead to disastrous consequences, The Forest service recommends a 40 - foot roadway width (two, 14' travel lanes and 4' shoulders) to accommodate emergency vehicles in high -wildfire potential areas. In addition, any bridges leading to the homesites should be strong enough to handle the weight of firefighting equipment (40,000 pounds). The Forest Service recommends road grades of less than 12 percent to allow access in areas of steep terrain. Entrance gates, often locked, should be able to be broken easily or keys left with local firefighting personnel. 3. Site Design Standards. Construction materials and site design standards are very effective methods of minimizing wildfire dangers. The Forest Service recommends the following specific measures applicable to County land use policies: • Untreated shake roofs are the leading cause of home losses in wildland areas. The Forest Service recommends that jurisdictions require the use of either treated wood shakes or non-combustible roofing materials, in areas identified as hazard areas; • Chimneys should be screened with noncombustible, wire mesh screening. Exterior attic and under floor vents should be covered with wire mesh to prevent sparks from being drawn in. Screening should also be used under porches or areas below the ground line. • A Safety Zone should be established around each structure. These include standard Forest Service recommendations including reducing ladder fuels around trees, trimming of lower branches and the establishment of a 30 -foot buffer of flammable vegetation away from the structure. This buffer increases as the percent of uphill or downhill slope increases. 10.4 Visual Resources Visual resources in the County are defined as those "viewshed corridors" that are particularly valuable to residents and visitors of the area. These areas are typically defined by the relationship between major roadways and specific topographic features. The definition of these areas is purely subjective, but serve to identify areas where land use policies may have considerable impact on the visual character important to the residents and visitors of the County. The following corridors where identified by Planning Staff as particularly important to the County, from a visual perspective: 1-70; SH 82; SH 133; and SH 13. The visual corridors, shown on the attached background mapping, are based on the viewplanes from each of these corridors. Of particular note is the recent designation of the portion of SH 133 from Carbondale to the Pitkin County line as a "Scenic Byway." Although this designation does not require any changes to local or regional land use policies, the designation validates the importance of this particular corridor. Local policies towards these areas should respect the importance in carefully planning for these areas, while at the same time not placing undue restrictions on a private property owner's ability to develop land. Policies for important visual corridors commonly applied throughout the Country include the following: • Requiring landscaping and buffer zones between corridors and approved structures; • Strongly encourage the use of clustered development to minimize visual impacts of subdivisions and commercial development; • Require more stringent lighting standards to minimize the impacts of dense development. 10.5 Existing Policies Towards the Environment Policies regarding the environment contained within the 1984 Comprehensive Plan are based on the following goal: "Encourage a land use pattern which considers the environmental sensitivity of the land, does not overburden the physical capacity of the land and is in the best interest of County Residents." The following discussion presents the primary Objectives and Policies currently in place that support this goal and summarizes the effectiveness of each of the policies. "Discourage the development of areas with identified severe environmental constraints," The single policy related to this objective focuses on the identification and avoidance of "severe" environmental constraints, namely active landslides, debris slides, unstable slopes, bedrock slides, major rnudflows, radioactive tailings and the 100 year floodplain. The primary issue related to the implementation of this goal is defining the specific constraint for a particular geographical location. The existing 1984 Comprehensive Plan Management District Map only identifies areas of "severe" environmental constraints. The map fails to allow Planning Staff to specifically identify the particular constraint. This becomes an issue because different land uses (residential, commercial, industrial, etc.) would require differing levels of mitigation, if possible, to address these constraints. One method of addressing this issue would be the development of specific environmental constraint overlays that address each of these areas of concern. "Protect riverfrontlnpanan areas from encroachment by development. " Policies related to this objective include possible requirements for the dedication of river frontage as common open space. This objective has never been fully utilized or incorporated into the development approval process. It is suggested that this policy be refined and incorporated into the County Floodplain recommendations. Specific refinements to protect and improve these areas include the following: = Removal of vegetation in riparian and shoreland and disturbance of groundcover adjacent to streams shall be prohibited. If permitted land uses disturb these areas, they should be re -vegetated as soon as possible; • Adequate erosion control measures should be incorporated on development site plans in areas containing riparian vegetation; • All efforts must be made to reduce stream pollution and interference with the natural changes of the stream and to enhance the value of the stream as an important natural and ecological feature. "Discourage new development that cannot mitigate major air or water degradation that will be a result of the proposal" This objective states that the County will require "major" development proposals to evaluate and mitigate their impact on air and water quality in the County. Although a valid concern to County residents, there is currently no definition of "major" developments in the Comprehensive Plan, the Zoning Resolution, or the PUD or Subdivision Regulations. Secondly, the level of analysis necessary to comply with this policy is not articulated in County policies. It is suggested that this policy remain in the Updated Comprehensive Plan, but be refined to identify the scope of the project's impact, the level of analysis necessary and a set of specific mitigation policies to address potential impacts. In addition, it appears that sufficient support exists to develop woodburning restrictions applicable to the entire County. Ensure that natural drainages are protected from soil erosion that would result from alteration." This objective is enforced by recommending that new development mitigate any potential erosion damage from the alteration of existing natural drainages. Specific mitigation has not been integrated into County land use policies. As suggested earlier, County Floodplain, Subdivision and PUD Regulations should be amended to specify the type of mitigation necessary to fulfill this objective. "Ensure that development on lands having moderate or minor environmental constraints consider the limitations of the land." The current Plan requires mitigation in these areas based on the specific management districts defined on the Comprehensive Pian map. This issue, surrounding the implementation of this policy, rests on the inability to define the specific constraint within an area defined in the Plan as a "moderate or minor" constraint. One method commonly applied to address this issue is a refinement of the constraint definitions. As discussed earlier, planning staff have data suitable for identifying specific hazard areas that are much more site-specific than the management districts developed in 1981. It is suggested that the environmental constraints be implemented through the use of 'overlay zones" that are based on separate hazard areas such as debris flows, soil conditions and slope characteristics. Furthermore, specific mitigation for these impacts should be developed and uniformly applied within the review process. "That development proposals consider soil constraints as a part of physical the (sic) limitation considerations." The single policy related to this objective requires the County to discourage development in areas with severe soil limitations. Specific areas that fit these criteria are not formally identified. In fact, development has been allowed in areas defined by the 1981 management districts defined as having "severe environmental constraints," but the specific constraint in these areas (soils, debris flows, slopes, etc.) is difficult to determine. Specific soil constraint overlays would assist staff in determining when and if this policy is triggered by a specific development proposal. "Encourage developers to recognize the unique physical features of the land and lay out the subdivision in a manner that is compatible with those features." The policy to implement this objective calls for the County to discourage development proposals that require excessive natural vegetation removal and cut and fill areas that will result in a visual degradation of the area. The definition of "excessive" or "visual degradation" is not formally defined. Again, overlays defining areas of specific visual importance would assist in ensuring the effectiveness of this policy. "Protect unique natural and scenic resources such as unusual vegetation and major wildlife habitats." As stated earlier, the failure to formally identify areas impacted by this proposal seriously restrict its implementation. Overlays and performance standards (design guidelines) would allow staff to more effectively address this objective. "Encourage development in areas with the feast environmental constraints prior to lands with greater physical limitations," This objective calls for the County to encourage the development of land with minor or no environmental constraints prior to the development of !and with severe or moderate environmental constraints. It assumes that some implementable tool (zoning, subdivision and PUD regulations) includes an ability to determine which areas are more conducive to development than others, what kinds of land uses are more appropriate than others and the unique standards for the area that will apply. None of these appear to be available with existing regulations. 10.6 Conclusions • The existing Management District Map, designed to address areas of minor, moderate and severe constraints, does not allow specific hazards to be identified and mitigated. Separate environmental overlay maps would be a more effective approach to ensure these constraints are addressed in the development review process. • Specific goals related to the protection of wetlands and riparian areas should be integrated into the Floodplain Regulations to ensure implementation. Professional assistance from the Division of Wildlife should be used to develop composite maps identifying areas of low, moderate and high wildlife impact areas. Furthermore, these maps should be integrated into the project review process. • Consensus should be reached regarding areas of serious geological and topographical constraints. The available data should be cataloged, and used to develop specific mitigation measures that will be consistently applied throughout the County. • Visual corridors and companion design guidelines regarding signage, setbacks, buffer areas and landscaping should be formally adopted and enforced by the County. • The County should develop woodburning restrictions as soon as possible. • Staff should continue to utilize State Forest Service personnel to assist in the review of projects located in wildfire areas and incorporate their suggestions in the review and approval process. PROGRAMS: 7.1 A High Groundwater/Septic System Constraints Map, based on previously collected technical data, will be developed and applied in the project review process to ensure that water and wastewater systems are designed in a safe, effective manner. For areas of the County that have not been mapped, it shall be incumbent upon the developer to evaluate the sub -surface conditions and their ability for adequately treating wastewater that would be generated by the project. 7.2 Modifications to the Zoning Resolution will include an assessment of the relationship between existing central water and sewer systems and future zone districts, particularly as it relates to density definitions. 7.3 In areas identified as having severe constraints to the use of ISDS, the developer shall install either centralized wastewater treatment facilities, or another engineered design approved by the State, or shall leave this land undeveloped. 7.4 A Water Constraints Map, based on the collection of geologic data, will be developed and applied to the project review process to ensure that potable water systems are designed in a healthy and safe manner and that an adequate water supply exists. 8.0 NATURAL ENVIRONMENT ISSUES: Issues related to the natural environment identified during the Comprehensive Plan process are as follows: • Tourism is an integral component of the economy of Garfield County. f,. -2A) T Therefore, it is essential that the planning process respect the natural environment that brings residents and visitors to the County; • The existing Management District Map, designed to address areas of minor, moderate, and severe environmental constraints, does not allow for specific hazards to be identified and mitigated; • Protection of air and water quality should be an essential component of the Comprehensive Plan and subsequent amendments to the Zoning Resolution and Subdivision Regulations; • Development should respect the natural contours and drainage patterns on each individual project site; • Important visual corridors should be identified and companion design guidelines regarding signage, setbacks, buffer areas and landscaping should be formally adopted and enforced by the County. GOALS: Garfield County will encourage a land use pattern that recognizes the environmental sensitivity of the land, does not overburden the physical capacity of the land and is in the best interests of the health, safety and welfare of Garfield County. Enhancement of the river corridor. The reclamation of land after extraction processes. Protection of watersheds and flood plains. Control of drainage that impacts the communities. OBJECTIVES: 8.1 The County of Garfield reserves the right to deny a project based on severe environmental constraints that endanger public health, safety or welfare. 8.2 Proposed projects will be required to recognize the physical features of the land and design projects in a manner that is compatible with the physical environment. 8.3 Garfield County will ensure that natural drainages are protected from alteration. 8.4 River -fronts and riparian areas are fragile components of the ecosystem and these areas require careful review in the planning process. 8.5 Development proposals will be required to address soil constraints unique to the proposed site. 8.6 Garfield County will ensure that natural, scenic and ecological resources and critical wildlife habitats are protected. 8.7 Development will be encouraged in areas with the least environmental constraints. POLICIES: 8.1 Garfield County shall discourage and reserve the right to deny development in areas identified as having severe environmental constraints such as active landslides, debris flows, unstable slopes, bedrock slides, major mudflows, radioactive tailings, slopes over 25 percent, riparian areas and wetlands and projects proposed within the 100 year floodplain. 8.2 Garfield County shall discourage development proposals that require excessive vegetation removal, cut and fill areas or other physical modifications that will result in visual degradation or public safety concerns. 8.3 Natural drainage patterns will be presented so the cumulative impact of public and private land use activities will not cause storm drainage and floodwater patterns to exceed the capacity of natural or constructed drainageways, or to subject other areas to an increased potential for damage due to flooding, erosion or sedimentation or result in pollution to streams, rivers or other natural bodies of water. 8.4 The County will require development with river frontage to address the issue through physical design in a way which will protect fragile wetlands and scenic resources and protect floodplains from encroachment. 8.5 The County will discourage development in areas where severe soil constraints cannot be adequately mitigated. 8.6 Garfield County will protect critical wildlife habitat needed by state and federally protected, threatened or endangered species. Development within these designations that cannot be designed, constructed and conducted so as to have a minimum adverse impact upon such habitat or these wildlife species, shall be discouraged; however, it is the intent of this policy, that no private landowner lose the ability to develop his/her land without fair compensation as a result of owning significant wildlife habitat. 8.7 Garfield County will require development on lands having moderate or minor environmental constraints to mitigate physical problems such as minor rockfalls, 17 to 24 percent slopes, minor mudflows, potential subsidence, high water tables, slow percolation, radioactive soils and/or corrosive and expansive soils. PROGRAMS: 8.1 Garfield County will explore options to integrate an environmental review process that is sensitive to differing levels of natural constraints throughout the County. Performance standards should be developed that ensure adequate mitigation of identified constraints. 9.0 NATURAL EXTRACTION ISSUES: RESOURCE Primary issues concerning natural resource extraction identified during the Comprehensive Plan process include the following: • The relationship between previously approved mining operations and residential development has resulted in visual, noise and traffic compatibility issues; ▪ The property rights of private property owners must be balanced with the rights of mineral lessees; • The County must be proactive in reacting to market conditions that will impact the level, location and scale of mineral extraction within the County; • Garfield County has significant mineral resources that has, and will continue to have, a considerable impact on the economic health of the County. GOAL: Garfield County recognizes that under Colorado law, the surface and mineral interests have certain legal rights and privileges, including the right to extract and develop these interests. Furthermore, private property owners also have certain legal rights and privileges, including the right to have the mineral estate developed in a reasonable manner and to have adverse land use impacts mitigated. OBJECTIVES: 9.1 The County will require adequate mitigation to address impacts of mineral extraction on private property owners, without undue burden on the legal rights of mineral lessees. 9.2 The County through the implementation of the Comprehensive Plan, Zoning and Special Use Permit policies, will address future compatibility issues with current mining operations. 9.3 The County will ensure that mineral extraction activities will not adversely affect the natural environment, including air quality, water quality, wildlife habitat or important visual resources. POLICIES: 9.1 Garfield County, to the extent legally possible, will require adequate mitigation to address the impacts of mineral extraction on adjacent land owners. These measures may include the following: A. Landscaping and screening; t3. Modification of phasing or area to be mined; C. Roadway improvements and signage; D. Safe and efficient access routes; E. Drainage improvements to protect surface and groundwater. 9.2 Garfield County, in coordination with relevant special districts, authorities and municipalities, will require that developers of energy or mineral extraction projects finance the construction and operation of any public improvements which, now or in the future, will be required by their projects. 9.3 Garfield County will require developers of mineral extraction projects to participate in and contribute to the funding of the County's monitoring of the demographic changes and socioeconomic impacts associated with such projects. The applicability of this policy will be assessed on a case-by-case basis by the Board of County Commissioners. 9.4 Dust, odors and fumes should be contained within the extraction site generating such emissions and should not negatively affect any surrounding land use. 9.5 Any proposal regarding mineral extraction that cannot mitigate adverse impacts may be denied based on a finding of incompatibility, for the following reasons: A. Adversely affecting the desirability of the immediate neighborhood or the entire community; B. Impairing the stability or value of existing adjacent properties; C. Adversely affecting the quality of life of existing adjacent residences; D. Showing a lack of quality or function in operational planning and/or design; E. Creating a public danger or nuisance to surrounding areas; F. Altering the basic character of adjacent land uses or the entire community. PROGRAMS: 9.1 The Garfield County Zoning Resolution will be revised to reflect the Goals, Objectives and Policies regarding resource extraction. It is suggested subdivision developers obtain all subsurface rights (mineral rights) associated with the land proposed for subdivision prior to Final Plat approval. All mineral leases and owners of record of the platted property shall be identified on the Final Plat. 9.2 Planning staff, with the cooperation of the Planning Commission, will revise the Special Use Permit process to reflect the need to ensure compatibility of mineral extraction activities with adjacent land uses. 10.0 URBAN AREA OF INFLUENCE ISSUES: Primary issues identified during the Comprehensive Plan process can be summarized as follows: • County land use decisions, particularly those immediately adjacent to municipal boundaries have, in some cases, created compatibility problems; • Due to the wide variety of Uses By Right within the County's current Zoning Resolution, planning staff has no discretionary review authority to prevent incompatibility situations with an adjacent municipality. GOALS: Ensure that development and overall land use policies occurring in the County that will affect a municipality are compatible with the existing zoning and future land use objectives of the appropriate municipality. \NestWater Engineering Consulting Engineers & Scientists 2' 16FORE5IGHT CIRCLE, tt August 24, 2010 Mr. Travis Morse US Army Corps of Engineers 402 Rood Ave., Room 142 Grand Junction, CO 81501 GRAND JUNCTION, 'COLORADO 61505 (970) 241-7076 - FAX (970) 241-7097 RE: Wetland Delineation and Nationwide Permit 12 verification for a Divide Creek crossing at the intersection of CR 311 and CR 335 in Silt, CO. Dear Mr. Morse: Antero Resources requested WestWater to perform a wetland delineation and Nationwide Permit (NWP) #12, Utility Lines Activities, for review and verification for an open cut ditch crossing of Divide Creek in Silt, CO. Antero Resources had intended to horizontal directionally drill (HDD) under Divide Creek at the intersection of CR 311 and CR 335. The intention of the bore was to eliminate potential impacts to wetlands adjacent to and including Divide Creek. During the boring process Antero encountered large boulders embedded in a sandy substrate. As the boring continued, significant difficulties were encountered when the boulders rolled in the loose substrate. This resulted in a crimped bore and Antero abandoned boring operations. To facilitate completion of the project, Antero would like to implement their contingency which is to cross Divide Creek and adjacent wetlands with an open cut ditch. WestWater conducted a thorough evaluation of the project area and delineated wetlands within the project area. This letter and pre -construction notification is a request to fulfill requirements for NWP #12. Pertinent information concerning this request follows. Please feel free to contact our office if you have any questions regarding this delineation, or if we can be of assistance in any way. Sincerely, Brett F. Fletcher Environmental Scientist) Wetland Biologist Wetland Delineation Divide Creek Prepared for: Antero Resources Prepared by: WestWater Engineering August 2010 Introduction WestWater Engineering (WWE) biologists were requested to perform a wetland delineation and file a pre -construction notification (PCN) for a Nationwide Permit (NWP) #12 verification request.

The project is located at this intersection. Total Project Site Acreage: Approximately 1.5 acres. Background Antero Resources had intended to horizontal directionally drill (HDD) under Divide Creek at the intersection of CR 311 and CR 335 (Figure 1). Antero Resources had intended to horizontal directionally drill (HDD) under Divide Creek at the intersection of CR 311 and CR 335. The intention of the bore was to eliminate potential impacts to wetlands adjacent to and including Divide Creek. During the boring process Antero encountered large boulders embedded in a sandy substrate. As the boring continued, significant difficulties were encountered when the boulders rolled in the loose substrate. This resulted in a crimped bore and Antero abandoned boring operations, To facilitate completion of the project, Antero would like to implement their contingency which is to cross Divide Creek and adjacent wetlands with an open cut ditch. Delineation Methods — WestWater biologists performed a wetland delineation of the project area on August 19, 2010. The wetland boundaries were identified on the basis of the vegetation, soils, and hydrologic characteristics present at the site in accordance with the Arid West Regional supplement to the Army Corps of Engineers (COE) Wetland Delineation Manual, September 2008. The wetland boundary delineation included identification of plant species, vegetation composition, and structure. Soil borings (18 f in. deep) were taken with an auger for observation of wetland soil and hydrology indicators within the potential wetland. Wetland boundaries were marked using orange flags. Boundary flags were located using a Magellan MobileMapper CX sub -meter accuracy GPS unit. Boundary flag and sample point UTM locations are Listed in Table 1. Data sheets were filled out for sample locations on Divide Creek and two locations in adjacent wetlands. Data sheets are attached to the end of this report. Table 1.

Adjacent wetlands appeared to have a source of hydrology independent of Divide Creek. It appears that hydrology to these wetlands is supplied by groundwater seepage from the irrigated pastures on the mesa west of the project area. Flags were placed along wetland boundaries, boundary line A and B, at their transition to uplands. Boundary line D indicates a dry island that is surrounded by wetlands in the project area. Data sheets were completed for wetland to upland transects near flags A06, A18, and B04 (Figure 2) and are attached to the end of this report. Proposed Construction and Impacts - It is Antero Resources intent to instal] coffer darns and divert flows through a corrugated metal pipe (CMP) while constructing the open cut ditch (OCD) through Divide Creek. Once the ditch has been backfilled and preconstruction contours have been reestablished, flow will be returned to the natural channel and the CMP will be removed. Antero estimates that the project will be completed within 2 weeks of commencement. Re -contouring and re - vegetation operations will also be completed in that time frame. Temporal impacts through the stream channel and adjacent wetlands are negligible considering the amount of time it will take to cut the ditch, lay pipe, back fill, and reestablish wetland vegetation. There will be no permanent impacts to WoUS or adjacent wetlands. Disturbance will be limited to 25 feet on either side of the centerline of the ditch (Figure 2). The ditch will be dug 5 feet deep and 3 pipelines will be installed. There will be a 12 inch water line in a 16 inch casing, a 12 inch steel gas line, and an irrigation water line (see attached Drawings). Top soil and vegetation will be removed and set aside until ditch work has been completed. Vegetation and top soil will be distributed once the ditch has been filled and the area returned to its pre-existing topography. No WoUS will be depleted or impounded during DCI} construction. It is WestWater's assertion that a "no significant impact" finding is warranted for temporally impacted WoUS. Antero Resources will submit before and after photos to the COE for the stream and wetland remediation once it has been completed. Threaten and Endangered Species Based on a review of federally listed species in Garfield County, on the US Fish and Wildlife Service website, it is likely the proposed project will have no effect on threatened or endangered species habitat. Table 2 contains the federally listed species in Garfield County. Table 2. Garfield County Threatened and Endangered Species Common Name Scientific Name Status Bonytail Gila elegans Endangered Canada lynx Lynx Canadensis Threatened Colorado pikeminnow Ptychocheilus lucius Endangered Humpback chub Gila cypha Endangered Mexican spotted Owl Strix occidentalis lucida Threatened Razorback sucker Xyrauchen texanus Endangered Threatened Uinta Basin hookless cactus Sclerocactus glaucus Utc ladies' -tress orchid Spiranihes diduvaialis Threatened The northern boundary for critical habitat for listed species in the Colorado River, Razorback sucker and the Colorado pikeminnow, is exit 90 (Rifle exit) north off Interstate 70. The confluence of Divide Creek and the Colorado River is approximately 8 miles upstream of the end of critical habitat. There is no other critical habitat within 10 miles of the project area. A web search was conducted on the National Register of Historic Places web site, www.colohistory- oahp.org, and no results were found in the project vicinity. There are no buildings or structures in the project area nor does the project area appear to meet any of the evaluation criteria for nomination to the National Register of Historic Places as listed in 36 CFR 60.4.

Once the ditch has been backfilled and preconstruction contours have been reestablished, flow will be returned to the natural channel. Antero estimates that the project will be completed within 2 weeks of commencement, including re -contouring and re -vegetation operations. Temporal impacts through the stream channel and adjacent wetlands are negligible considering the amount of time it will take to cut the ditch, lay pipe, back fill, and reestablish wetland vegetation.
