Exp. 0923.2009 (Notary :vh..:c) Description of Project: The Valley Farms F4 Production Well will be converted to an injection well pending COGCC approval. This well will receive produced water and flowback water from Antero Resources Piceance Corporation (Antero) Piceance Gravel Trend and Castle Springs Production operations. Injection pressures will be developed using a skid mounted pumping facility (pumps, controls, meters, etc. enclosed in a metal sided building approximately 40'x12'x12'). A set of 6 water tanks will be added to the existing 6 tanks located on this site. The existing tank farm is comprised of 4 water tanks and 2 oil storage tanks, each with a capacity of 300 bbls. The proposed total additional capacity of water storage tankage is 1800 bbls. A back up natural gas engine driven electric generator will also be added to the site and will be housed in a separate building. High density polypropylene (HDPE) 12" water lines (2 in parallel) currently exists throughout the Piceance operating field and will transfer produced water and/or flowback water to this location for injection thus eliminating a minimum of 40 truck (100 bbls/truck) trips per day on the public roads. It should be noted that this pipeline system does not extend to all existing well locations (e.g. north of the Colorado River) but it is our intent to connect as many locations to this pipeline system to reduce truck traffic. For those locations not served by pipeline, we will truck water to an unloading point on the water pipeline system in order to convey the water to the injection facility or for recycle purposes. Antero's access rights in and to the well pad site and to the piped system above described have been established over the course of the last four years of expanded drilling and production operations pursuant to numerous lease and surface use agreements with the applicable land owners. Pursuant to said rights, Antero has constructed, operated and maintained the components of this system over the course of said four year period to and through the present date. As noted above, Antero's proposed level of use instant to such access will far less than its heretofore established drilling and production operations. Consistent with the above, Antero represents that produced water delivered to the proposed injection facility will be by pipeline only, except in emergency situations (e.g. pipeline system not operational due to plugging, repairs or other acts beyond the reasonable control of Antero). Waters from the locations where this pipeline has not been constructed requiring truck transportation will be unloaded at Wasatch Bench or other approved unloading facilities. These waters will then be inserted into the pipeline for conveyance to the injection facility. Under proposed normal operations, trucking to this injection facility for the purposes of unloading water for injection will not be done. Wasatch Bench is a produced and flowback water receiving, treatment, storage and pumping facility which has a dual synthetic lined pit of approximately 200,000 bbl capacity complete with leak detection and groundwater monitoring wells. It has multiple truck unloading and loading stations, treatment tanks, a 200,000 bbl pit and pumping facilities. Water trucks unload their contents into the treatment tanks whose effluent is discharged into the pit for storage for either reuse/recycle for fraccing purposes or for water injection at this facility or for trucking out of the area for disposal by other means. These water trucks are used for transporting water from locations that are not on the water pipeline system. Support Materials for Article III and Article IV The proposed facilities and usage will comply with pertinent portions of Articles III and VII of the Unified Land Use Resolution of 2008. Following is a discussion of those applicable sections. Section 7-101 Compliance with Zone District Use Restrictions. The proposed land use change complies with applicable zone district use restrictions and regulations in Article III, Zoning. Section 7-102 Compliance with Comprehensive Plan and Intergovernmental Agreements. The proposed land use change is consistent with applicable provisions of the Garfield County Comprehensive Plan and any intergovernmental agreements between the County and a municipality that applies to the area where the use will occur. Section 7-103 Compatibility. The proposed land use change is consistent with the existing land use and will minimally affect the adjacent land uses. The change will not require any additional land disturbance or change the drainage of the area. The proposed use is compatible with the existing use and will not result in an adverse impact to adjacent land. Section 7-104 Sufficient Legal and Physical Source of Water. The proposed land use change will not require additional water for its operation and maintenance. The proposed facility will not require the installation of a water production well. On the contrary, the facility will be a produced water disposal well. Section 7-106 Adequate Central Water Distribution and Wastewater Systems. The land use change will not require a water distribution system or connection thereto; likewise, the change will not require additional wastewater systems since this site utilizes portable toilet facilities. Section 7-107 Adequate Public Utilities. Electrical service to power the injection pumps will be provided from CR 331 Airport Road just to the north of the site. We believe that no other public utilities will be required. Section 7-108 Access and Roadways. Access to this site will be by existing roadways and easements. No additional access easements or roadways will be required. Vehicles traveling to this site, after construction, will be pick up type trucks and smaller maintenance vehicles. Since this facility will receive produced water by existing pipeline, the number of trucks required for to serve this area due to our operations should decline significantly. The estimated incremental number of truck trips to operate and maintain this facility will be less than 5 per week on average. Safe Access. The incremental traffic accessing this site will not cause an unsafe situation. The current access is designed to accommodate large drilling and completion equipment transported by multi -axle vehicles. Adequate Capacity. Access serving the proposed use has the capacity to accept the additional traffic generated by the use safely and efficiently. The use is not expected to cause traffic congestion or unsafe traffic conditions. We do not expect the impact for the proposed usage to be adverse or significant due to the expected reduction of water truck traffic in the area. Section 7-109 No Significant Risk from Natural Hazards. The use is not subject to significant risk from natural hazards and will not exacerbate existing natural hazards. The site is not in the floodplain. It is in the Moderate Slope Hazard area designation but no additional site preparation or earthwork is planned to accommodate this use change. The site is not located in areas designated as Coal Mine, Major or Moderate Soil Hazards. The site is located in areas designated as Low Wildfire Hazard. The site is located outside of Garfield County Visual Corridor. Section 7-201 Protection of Agricultural Lands. No Adverse Affect to Agricultural Operations. The proposed land use change will have a negligible effect on agricultural operations because Antero does not expect to expand the pad size to accommodate the facilities proposed herein nor to have a net increase in traffic or general disruption to agricultural operations. In addition, dust control measures will be put in place during and after construction, to minimize adverse impacts to livestock and crops Fences. No additional fencing is planned at this time for this land use. A natural barrier consisting of steep fill areas on two sides and steep cut areas on the other two sides currently exists. Roads. The existing access road will be utilized for the operation of the proposed facility. The proposed facility well pads and access roads are graveled to stabilized the surface with respect to erosion control and as a best management practice to mitigate fugitive dust emissions. Irrigation Ditches. The proposed land use will not impact the use or maintenance of the irrigation ditch to the north of the site. Stormwater best management practice controls and secondary containment for the bulk storage of liquids on site will be either improved and/or maintained to protect the adjoining property and irrigation ditches from an accidental release of harmful substances or sediment. Secondary containment for the proposed water storage tanks will be increased as per the SPCC regulations and these changes are documented by the facility diagrams in the SPCC Plan for the Valley Farms D & F Well Pads. In addition, the Valley Farms D & F well pads are configured with tertiary containment via pad perimeter berms so that in the event of a spill there are additional protections that act to further contain a spill to the well pad location. The SPCC plan and the Stormwater Mangagement Plan is presented in the Appendices. Protection of Wildlife Habitat Areas. WestWater Engineering (Westwater) was contracted to perform wildlife field surveys, assessments of wildlife habitats and habitats for sensitive plant species on the proposed project area. The findings of Wildlife evaluation for these facilities are memorialized in a report that is presented in the Appences. WestWater concluded that because the proposed project does not involve new surface disturbance to areas that have not already been disturbed, the proposed project will have minimal impacts on wildlife resources in this area. The report is entitled "Wildlife and Sensitive Areas Report, Valley Farms Injection Wells D & F, Garfield County Colorado (Wildlife Report). Section 7-203 Protection of Wetlands and Waterbodies WestWater was contracted to evaluate the potential jurisdictional Waters of the United States in the proposed project area. The results of this survey identified one existing potential jurisdictional Army Corps of Engineer crossing and a culvert is already in place to mitigation this impact, Otherwise, there are no wetlands or waterbodies in the vicinity of the proposed project. The findings from this evaluation are found in the WestWater Wildlife Report as presented in the Appendices. Section 7-204 Protection of Water Quality from Pollutants. The Valley Farms D & F well pads are included in Antero's CDPHE stormwater management plan and the CDPHE stormwater general permit for construction. The proposed facilities are also included in the Antero Spill Prevention, Control and Countermeasure (SPCC) plan as per U.S. EPA Regulations, 40 CFR 112. To reduce stormwater impacts during construction and operation of these facilities, Best Management Practices (BMPs) will be utilized to protect surface water from stormwater runoff. The proposed facilities also include a well pad perimeter berm to reduce stormwater runoff. The stormwater BMPs for the proposed facilities are presented in the Stormwater Management Plan and presented in the Appendices. The CDPHE General Permit is presented in the Appendices. The SPCC Plan has been prepared and it is presented in the Appendices. The SPCC plan presents detailed descriptions of the best management practices in place at Antero's well pads to prevent and control spills to the environment. The proposed facilities have been designed with secondary and tertiary containment in the form of containment structures around the tank batteries and well pad perimeter berms. The secondary containment for the tank batteries consists of a synthetic liner beneath the tanks and a steel containment structure around each tank battery. The liner will be carried up the side of the steel containment structure. The SPCC plan will be revised to account for the new storage tanks and will be fully implemented prior to operation of the proposed project. This facility will not include any vehicle or mobile machinery maintenance operations, no waste storage areas. Antero also developed an Emergency Response Plan for its Rifle -Silt operations and the purpose of this plan is to control or limit any effect that an emergency or potential emergency will have on any personnel, properties or the environment. A copy of the Antero Emergency Response Plan is available for review in the Rifle office. Section 7-205 Erosion and Sedimentation The Valley Farms D & F Injection well pads are included in the Antero CDPHE Stormwater General Permit and the Antero Stormwater Management Plan. During construction and operation of the proposed facilities, appropriate BMPs will be utilized to minimize stormwater runoff and consequently erosion and sedimentation. The BMPs for the proposed facility are presented in the Appendices. Section 7-206 Drainage. The site is graded to provide a 1% slope across the location for positive drainage. The proposed facilities have been designed with pad perimeter berms to minimize the discharge of stormwater runoff from each injection well facility to adjacent properties. Therefore, no adverse impacts are anticipated for adjacent properties.. Section 7-207 Stormwater Runoff The proposed injection facilities are included in the Antero CDPHE Construction Field -Wide Stormwater General Permit and the Stormwater Management Plan. To reduce sedimentation impacts during construction and operation of the proposed facilities, BMPs will be utilized to protect surface waters from stormwater runoff. Section 7-208 Air Quality The proposed project is not anticipated to adversely affect air quality. The proposed project includes the addition of produced water storage tanks. However, storage tank venting of volatile organic compounds (VOC) will be routed to the existing air pollution control device (combustor) to control odors and minimize emissions VOC emissions. Storage, collection and disposal of produced water and flowback water through the use of the proposed facility in conjunction with the existing water pipeline will significantly reduce the emission of air pollutants as compared with current operating practices. Section 7-209 Areas Subject to Wildfire Hazards. The proposed project is located in an area designated as low fire hazard as per the Garfield County Wildfire Hazard. The proposed land use change does not increase the intensity or duration of a wildfire. The materials stored will not increase the fire potential for this area. Section 7-210 Areas Subject to Natural Hazards and Geologic Hazards Avalanche. The proposed site is not subject to avalanche, landslides, mudflow, rockfall, unstable soils and does not have natural radioactive minerals in rock, soil or water. Section 7-211 Areas with Archeological, Paleontological or Historical Importance. Grand River Institute (GRI) was contracted to conduct a Class I cultural resource inventory for the Valley Farms D and F pad locations. The ensuing GRI report is presented in the Appendices. The purpose of the Class I cultural resource investigation was to identify previously recorded resources within or near the Valley Farms D and F pad locations that may be adversely affected by the proposed action. The potential for additional cultural resources in the project area was also evaluated. The findings of this report conclude that as per the files search conducted by the GRI, no sites have been previously recorded within the proposed project areas. Three historical ditch segments were identified along Dry Hollow Creek but all are located outside the proposed project area. Moreover, two other ditches were documented on U.S.G.S. maps that have not been recorded. However, these ditches occur outside the area of disturbance. The GRI concluded in their report that no further consideration of cultural resources is recommended for the proposed project Section 7-212 Reclamation Westwater was contracted to prepare an "Integrated Vegetation and Noxious Weed Management Plan" (Reclamation Plan) and this plan is presented in the Appendices. Section 4.0 of the plan addresses the revegetation and reclamation of the proposed project area. The project area is composed of arid agricultural meadows, grass and shrubland rolling hills and sparse foothill woodlands. Successful reclamation of the project area is dependent upon soil type and texture, slope gradient and aspect, proper weed control, available water and revegetation with suitable plants. All of these concerns are addressed in Section 4 of the Reclamation Plan. Interim and final reclamation goals will be consistent with those outlined in the COGCC amended rules effective April 1, 2009. These regulations are expected to fulfill Garfield County's requirements for interim and final reclamation standards. Section 7-301 Compatible Design. A. Site Organization. This is an existing site with no expansion planned under this project. The site will not impede adjacent lands from solar radiation, parking, pedestrian traffic or access to any common areas. B. Operational Characteristics. The operations planned for this project will not create nuisances to adjacent users since the operations will be automated with little to no additional truck traffic to this site. Condensate trucking may increase slightly at this site, however, overall truck traffic in the area will decrease. We expect no burden to others regarding parking, service delivery or other uses in the area as a result of this project. 1. Objectionable Emissions. We expect a net reduction of dust, odors, gas, fumes and glare to the general areas as a result of this project. Dust control measures will continue for this site and include the graveling of the pad and watering of the access road.. VOC vapors from produced water and condensate storage tanks vents will be collected and routed to the existing combustor for pollution control and odor mitigation. Odors, VOC emissions, fugitive dust and Oxides of Nitrogen (NOx) from truck exhaust will be all be reduced due to the movement of produced water from the well pads to the proposed facilities using a buried pipeline as opposed to truck hauling. Rick — Not too sure how to word this but I like the idea of decereased impacts due to water movemt via pipeline vs truck. Glare from the proposed tanks and buildings will be minimized by paint color selection and optimal location and orientation. Paint colors will be such that facilities blend into the surroundings. Additional tanks will be situated immediately adjacent to the existing 12' cut which blocks them from view by the adjacent homeowners. Glare from trucks on the road will be reduced. 2. Noise. Noise as measured at the property boundary is not expected to exceed COGCC noise standards on a long term basis Rick — could you say for industrial areas — what noise std applies??. During testing and startup operations of the pumping facilities we expect to power the pumps with electricity generated on site by a temporary diesel engine (approximately 200-300 hp). However, Antero plans to obtain permanent electrical service to power the pump motors and this will significantly reduce the noise associated with the use of the diesel generators. Antero plans to house the diesel genset in a temporary building structure to reduce the noise impact to the area. Nevertheless, the noise impacts due the temporary operation of the diesel genset will not exceed the COGCC limits. 3. Hours of Operation. This facility will operate 24 hours per day and under normal circumstance will not be attended. 4. Roadway System Impacts. The overall impacts from this project on the roadway system will marginal because there will I be a net reduction of water trucks on the roadway system because the produced water from existing well pads is designed to be delivered to the proposed facility via an underground water pipeline This project will lessen the impacts on the roadways because the produced water that is currently either trucked to the Danish Flats Water Handling Facility in Utah, trucked to the Wasatch Bench Water Handling facility or trucked to the Castle Springs injection well will be terminated when the injection wells commence operation. C. Lighting. We are not planning to install any additional outdoor lighting at this facility as a result of this project. Lights interior to the buildings will be normally off. D. Buffering. We plan to buffer the noise generated by the temporary diesel engine by using a noise reducing equipment such as shrouds, buildings or barriers. We plan to use hay bales to visually and audibly buffer the site. E. Materials. The exterior facade of the proposed buildings will be constructed with materials that do not detract from adjacent buildings or uses. F. Building Scale. The scale of buildings on the site will relate to the scale of structures on adjacent properties and the nature of the proposed use. Section 7-303 Design and Scale of Development. The design and scale of the proposed development will not have excessive site disturbance, impact airport operations and is located near to utilities and roads. Agricultural land will be preserved. Section 7-304 Off-street Parking and Loading Standards The proposed project will not require any off-street parking and any loading will be done on location. Section 7-305 Landscaping and Lighting Standards There will be no additional disturbed areas for this project. The existing pad location will undergo routine, authorized restoration and revegetation as required by the COGCC reclamation standards. Section 7-306 Snow Storage Standards The proposed project does not include a designated parking areas since this facility will be unmanned. Section 7-307 Roadway Standards The project does not include any proposed roadways. Section 7-308 Trail and Walkway Standards The proposed project does not include any trails or walkways. Section 7-309 Utility Standards The proposed permanent electrical service will be located in an approved easement and will be above ground construction. DIVISION 4 SUBDIVISION STANDARDS AND DESIGN SPECIFICATIONS The proposed project does not include any subdivision. Section 7-810 Additional Standards Applicable to Industrial Use A. We do not plan to conduct any fabrication at this facility subsequent to the initial installation of planned facilities. Any service and repair operations for the pumping facilities or the generator will be conducted within the enclosed building or obscured by a fence, natural topography or landscaping. B. All operations involving loading and unloading of vehicles shall be conducted on private property and shall not be conducted on a public right-of-way. C. All outdoor storage facilities for fuel, raw materials and products shall be screened by natural topography or enclosed by a fence or wall adequate to conceal such facilities from adjacent property. 1. All outside storage abutting or facing a lot in a residential or commercial zone shall be screened by natural topography or enclosed by a site -obscuring fence to obstruct the storage area from view. The fence shall be of material and design that will not detract from adjacent residences. D. All industrial wastes shall be disposed of in a manner consistent with statutes and requirements of CDPHE and COGCC. E.

The public access to the site is from CR 331 Dry Hollow Road to Mineota Drive. 2. Access to adjoining Roadways. Access to adjoining roadways will not be altered or impacted as a result of this project. Site distances will be addressed in the Traffic Study but does not appear to be a potential problem since this is an existing facility wherein no issues have come to Antero's attention in terms of access and site distances. The slight increase in vehicular traffic to and from this site (additional pickup truck trips and condensate truck trips) is not expected to be significant. The decreasing water truck trips made on this public road and in the area resulting from this project should more than compensate for any increase traffic to and from this particular site. 3. Easements. Easements are shown on the Site Plan drawing. This project should not impact any existing easements on the site. 4. Topography and Slope. This is an existing site with no change in topography or slope. The site is located in on the edge of a moderate slope hazard area as designated by Garfield County. See Garfield County Slope Hazard exhibit attached. 5. Natural Features. No significant natural features are present at this site. This site is situated in a natural depression with native grasses. 6. Drainage Features. The site plan shows the drainages on this site. No significant drainage changes other than the installation of secondary containment around the proposed water tanks is planned. The site is constructed with a drainage culvert beneath the finished grade to permit the drainage of stormwaters from the natural draw. The existing drainage features for the proposed facilities are described in Section 4.7 of the WestWater Wildlife Report. This report is presented in the Appendices. 7. Water. We do not plan to use any additional water for this project. The site has no springs, seeps, impoundments, wetlands or creeks. There is a natural drainage which has been preserved with installation of a culvert. 8. Floodplain. The site is not located within the 100 year flood plain. See Flood Plain exhibit. 9. Soils. The soil type for the proposed project area include loams and sandy to gravelly loams that overlay broken shale derived from the Green River Formation. Soil types present in the project area are those commonly found along the Colorado River's floodplains. Mapped soil types, as published by the Natural Resources Conservation Service, U.S. Department of Agriculture, were reviewed to make this determination. The soil types identified in this area are presented in Section 2.2 of the WestWater Integrated Vegetation and. Noxious Weed Management Plan. This report is presented in the Appendices. See Generalized Soil Types, Garfield County exhibit. The soils are alkaline and loose. 10. Hazards. There are no known geologic hazards on this site. 11. Natural Habitat. Field inspections were conducted by WestWater on July 8, 2009 to identify existing flora and fauna habitat, wetlands, migration routes. The results or their findings are presented in Section 2.0 of the Integrated Vegetation and Noxious Weed Management Plan. In addition, the WestWater Wildlife Report also addresses these concerns in Secton(s) 3.0 Wildlife and Plant Surveys, Section 4.0 Results of Survey, and Section 4.7 Army Corp of Engineers. The flora communities for the proposed project area, and in the vicinity of the project area, consist of a mixture of agricultural field and sagebrush shrublands with a grass understory. Widely scattered pinon-juniper woodlands lie on benches south of the project area. The Harrington Beardtongue (Penstemon harringtonii) is the only threatened, endangered, and sensitive species (TESS) with the potential to occur in the vicinity of the proposed injection wells. This species occurs most often in sagebrush shrublands and less commonly in pinon-juniper woodlands therefore WestWater concluded that the project area was outside the known range for Harrington beardtongue. In addition, WestWater concluded that the terrain and soils do not appear suitable for any other species of TESS plants. The above reports evaluated the critical habitats for federally listed threatened, endangered, and candidate fish and wildlife species and the potential impacts of this project on these habitats. In addition, a list of Birds of Conservation Concern (BCC) and their habitats were also evaluated by this review. Two federally endangered fish are known t occur in the Colorado River north of the project site. However, WestWater concluded that the designated critical habitat for the federally endangered Colorado pikeminnow and the razorback sucker lies downstream from the project area. WestWater determined that five state listed threatened, endangered, or special concern species may occur within the project area. However, WestWater concluded that, as a result of their surveys, no observations of state listed threatened or endangered wildlife were made in the area of the proposed injection wells. Several raptor species nest, reside, forage or pass through the general area of the proposed injection wells. Raptor species common to this area include the Golden Eagle, Bald Eagle, Red-tailed Hawk, American Kestrel, Cooper's Hawk, Sharp -shinned Hawk, Northern Harrier, Long-eared Owl, and Great Horned Owl all of which are identified on the BCC list. WestWater performed a raptor survey within .25 miles of the project area and did not identify any nests. In addition, no know Bald Eagle nest sites are located within the project area, Colorado Division of Wildlife (CDOW) records indicate that Bald Eagle winter range and roost sites are located along the Colorado River, more than 0.3 miles north of the project area. WestWater also surveyed the project area for presence of sensitive BCC (non -raptor birds) in the project area and their habitat. The findings of this survey are that no sensitive BCC were observed and that suitable habitats for these birds were not identified in the project area. The Greater Sage -Grouse is recognized by the BLM and CDOW as a bird species of special concern. The project area is located more than 2 miles from the nearest CDOW-mapped historic Greater Sage -Grouse habitat. WestWater concluded that it is unlikely that sage -grouse will occur on the project site due to the limited amount of sagebrush and that the proposed project does not include new surface disturbance to areas that have not been disturbed. Both of the injection wells are situated within mule deer and American elk winter range and severe winter range, as well as mule deer critical winter range. In addition, the Valley Farms F Pad injection well resides within a mule deer winter concentration area. WestWater concluded that the proposed facilities would result in the temporary loss of a small amount of elk and mule deer winter ranges. 12. Resource Areas. Grand River Institute (GRI) was contracted to conduct a Class I cultural resource inventory for the Valley Farms D and F pad locations. The ensuing GRI report is presented in the Appendices. The purpose of the Class 1 cultural resource investigation was to identify previously recorded resources within or near the Valley Farms D and F pad locations that may be adversely affected by the proposed action. The potential for additional cultural resources in the project area was also evaluated. The findings of this report conclude that as per the files search conducted by the GRI, no sites have been previously recorded within the proposed project areas. Three historical ditch segments were identified along Dry Hollow Creek but all are located outside the proposed project area. Moreover, two other ditches were documented on U.S.G.S. maps that have not been recorded. However, these ditches occur outside the area of disturbance. The GRI concluded in their report that no further consideration of cultural resources is recommended for the proposed project 'Th) z O 8 o E h n = N n g ri n $ em s I o o < : ci: ;L:77 E 2 1 w m c f c 4 t V 2 z 1 Date Prepared: 7-15-2009 II I Impact Analysis 1. Adjacent Property. This application contains a list of real property owners near or immediately adjacent to the pad location. The parcel is large as depicted in maps provided in this application. The site is a leased portion of the parcel and is about 2.02 acres in size. 2. Adjacent Land Use. Within a 1500' radius, the current land use is primarily rural residential with some agriculture to the immediate north. The parcels to the south are rural residential single family homes. The parcel upon which the site is located is a large tract which is zoned rural residential but is currently used for agricultural purposes. The site is located on the southern boundary of this tract. To the north of this large parcel are single family dwellings. 3. Site Features. This site is situated in a natural depressed area atop a low mesa. There is no natural water feature on site and is not subject to flood (see Flood Map included). Ground water is expected to be more than 100' from the surface. The site appears to have never been developed and has been in its natural state until the oil and gas well pad location was constructed several years ago. This application does not seek to expand the pad. The project area lies south of the Colorado River on a terrace west of Dry Hollow. Overall, the areal terrain is relatively flat with elevations ranging from about 5,220 feet to about 5,640 feet. Benches and hills dominated by pinon-juniper woodlands lie south of the project area. The vegetation of the project area consists of a mixture of agricultural fields, and sagebrush shrublands with a grass understory. 4. Soil Characteristics. The proposed use of the site will not be impacted by the existing soils and their characteristics. The existing site will not be expanded or modified beyond the addition of water tanks of identical size as currently located there as well as a pump house and backup generator house. The soil type for the proposed project area include loams and sandy to gravelly loams that overlay broken shale derived from the Green River Formation. Soil types present in the project area are those commonly found along the Colorado River's floodplains. Mapped soil types, as published by the Natural Resources Conservation Service, U.S. Department of Agriculture, were reviewed to make this determination. The soil types identified in this area are presented in Section 2.2 of the WestWater Integrated Vegetation and Noxious Weed Management Plan. 5. Geology and Hazard Valley Farms F pad: The surface geology of the area in which this site is located is characterized by low mesas, alluvial fans, and river beds with shallow sandy clay topsoils, underlain by stiff clays, weathered shale and sandstone, siltstone, and shale bedrock of the Wasatch Formation. Soils in this area include Potts loam, Arvada loam, and Ildefonso stony loam. On the north side of this site, there are 25-45 percent slopes and on the south side of this site, there are 6-12 percent slopes (source: Soil Survey Geographic (SSURGO) Database). Registered domestic water wells with the Colorado Division of Water Resources indicate ground water depths to the north of the site to be found at approximately 100ft or less; well data to the south of the site suggests groundwater is found at approximately 250ft (average of 7 wells to the south and west). At the time of the submittal of this application, there are no potential natural or man-made hazards for this site associated with its geology. 6. Effect on Existing Water Supply and Adequacy of Supply. The proposed land use change will not require any water and will not place a demand on any water supplies. 7. Effect on Groundwater and Aquifer Recharge Areas. This project will not adversely impact the groundwater or aquifer recharge area because there will be no land application of materials, no disposal of wastes on surface areas or subsurface areas which can communicate with the groundwater or aquifer recharge area, and finally, all stored materials on site will have secondary containment to capture spills or releases. The entire site is contained by berming thus providing a tertiary level of containment. 8. Environmental Effects. WestWater Engineering was contracted to evaluate the Environmental Effects associated with the proposed injection wells. The impacts of the injection well project on the flora and fauna, wildlife habitat, noxious weeds and archaeological resources, is documented in the attached WestWater reports. These include; Report on the Class I Cultural Resource Inventory for a Limited Impact Review, Wildlife and Sensitive Area Report, and finally the Integrated Vegetation and Noxious Weed Management Plan. The SPCC Plan for the proposed project is included in this application. The SPCC plan presents detailed descriptions of the best management practices in place at Antero's well pads to prevent and control spills to the environment. The proposed facilities have been designed with secondary and tertiary containment in the form of containment structures around the tank batteries and well pad perimeter berms. The secondary containment for the tank batteries consists of a synthetic liner beneath the tanks and a steel containment structure around each tank battery. The liner will be carried up the side of the steel containment structure. 9. Traffic. As previously stated in this application, we believe that the impact to local traffic Toads will be positive, i.e. reduce the loads on the streets and highways since transportation of water for disposal will be by underground pipeline versus water truck hauling. A traffic study was performed by Kimley- Horn and Associates, Denver, Colorado and is included in the Appendices. 10. Nuisance. Impacts on adjacent land from generation of vapor, dust, smoke, noise, glare or vibration, or other emanations will be mitigated as much as possible as follows: Vapor: vapors from tank storage will be collected and routed to a vapor combustor located on site. 7 - ^ 0 , Dust: dust will be suppressed by pad and access road maintenance under our routine operation of gravel application to the site and water application to the roads by water truck. Smoke: combustors, tank heaters and any other flame producing equipment will be operated and maintained to minimize smoke generation. Smoke from diesel exhausts will be minimized by routine maintenance of engine equipment. 11. Reclamation Plan. Westwater was contracted to prepare an "Integrated Vegetation and Noxious Weed Management Plan" (Reclamation Plan) and this plan is included in this application. Section 4.0 of the plan addresses the revegetation and reclamation of the proposed project area. Interim and final reclamation goals will be consistent with those outlined in the COGCC amended rules effective April 1, 2009. These regulations are expected to fulfill Garfield County's requirements for interim and final reclamation standards. -r1 Kimley-Horn �f 1 and Associates, Inc, July 15, 2009 ■ Suite 456 990 South Broadway Denver, Colorado Antero Resources Corporation 80209-4273 1625 17th Street, Suite 300 Denver, CO 80202 Attn: Rick Blankenship Manager, Health and Safety Re: Traffic Study — Trip Generation Identification Valley Farms D Pad and F Pad Injection Wells Garfield County, Colorado Dear Mr. Blankenship: The purpose of this letter is to provide an estimated trip generation for the proposed Valley Farms D Pad and F Pad injection Wells for Antero Resources Corporation. Valley Farms is located south of Silt in Garfield County, Colorado. Pads D and F are located along Dry Hollow Road as shown in the attached map. These proposed Pad D and F injection wells will include a pipeline system to bring water to the pads rather than by use of trucks, which is presently the procedure today. Therefore, providing these two pads (D and F) with injection wells will reduce the overall traffic on the surrounding street network by reducing the trucks hauling water from the production pad sites to existing injection wells. Based on comments from Garfield County, this report is to serve as a requirement for the project limited impact review. To estimate the potential trip generation of the proposed Valley Farms Pads D and F injection wells, traffic counts were conducted at an existing injection well. The Antero Resources Corporation Pad T injection well located along Divide Creek Road was counted on Thursday, July 9, 2009 between 7:00 AM and 7:00 PM by Ridgeview Data Collection (count data attached). This injection well will operate similarly to the proposed two injections wells, but this site has no pipeline system. Therefore, vehicle classification counts were conducted of the daily and peak hour counts to identify the trip generation anticipated for the D and F pads. The following table identifies the vehicles generated by the existing Pad T injection well site along Divide Creek Road.

Mr. Rick Blankenship, Antero Resources Corporation July 15, 2009 - Page 2 With the proposed Pad D and F injection wells, it is anticipated that the 18 -Wheel and 10 -Wheel trucks will no longer be needed due to the pipeline being installed to carry the water. One pumper truck is anticipated to be generated each day instead. The same number of pick-up/passenger vehicle trips is anticipated to be generated by the employees of the pad sites. The following table identifies the anticipated vehicle generation for each of the Pad D and F sites. Pad D and F Sites — Existing Vehicle Generation Count Period Pumper Truck Pick Ups Total AM Peak 0 1 _ 1 PM Peak 0 1 1 Daily (7 AM to 7 PM) 1 13 14 Therefore, each of the Pad D and F injection wells is anticipated to generate 14 vehicles per day, making a total of 28 trips (one in and one out). During each of the moming and afternoon peak hours, on average just one peak hour trip is anticipated. Again, by providing these two sites as injection wells with a pipeline system is anticipated to reduce the overall truck traffic on the surrounding street network. A reduction of 27 trucks per day (reduction of 28 water and condensate trucks to Pad T plus 1 pumper truck needed for Pads D and F) is anticipated. Therefore, providing injection wells on Pads D and F is not anticipated to negatively impact the surrounding street network. Since traffic volumes are anticipated to be reduced, a positive impact to traffic is anticipated. If you have any questions pertaining to this traffic analysis, please feel free to contact me.

May 2008 7 Antero Resources Piceance Corporation Spill Prevention, Control, and Countermeasure Plan Oil Production Facilities SECTION 2 SPCC PLAN POLICIES AND PROCEDURES This Spill Prevention, Control and Countermeasures (SPCC) Plan is a carefully conceived document prepared to address multiple onshore oil production facilities in Colorado operated by Antero Resources Piceance Corporation (Antero Resources) that are subject to the federal SPCC regulations. A complete list of facilities covered by this plan can be found in Table 1. As there are no State of Colorado SPCC -related requirements more stringent than the U.S. Environmental Protection Agency (EPA) oil pollution prevention regulations (40 CFR 112), this plan was developed to satisfy the federal requirements. Specifically, this SPCC Plan was developed to: • Communicate pollution prevention requirements to Antero Resources employees. • Document Antero Resources SPCC procedures and measures. • Enable Antero Resources employees to report a spill and provide all the necessary information in the event of a release. • Assist Antero Resources in contacting the appropriate agencies. • Provide site-specific information quickly and easily. Based on the type of operating facilities, the plan addresses both the general SPCC plan regulatory requirements specified in 40 CFR 112.7 and those specific to onshore oil production facilities included in 40 CFR 112.9. General requirements applicable to each facility and to the overall management of SPCC -related activities are included in the main text portion of the plan. Appendix A provides site specific information for each individual facility covered by the SPCC plan. This information includes a site layout, description of equipment, volume and type of material stored, surface water flow directions, and spill prevention controls. This plan conforms to the SPCC Regulations and was developed in accordance with sound engineering practices. Any deviations from regulatory requirements that were noted during the development of this plan are noted on Table 2. A complete copy of the SPCC Plan is maintained at the Rifle Field Office and at the Denver Corporate Office. 2.1 Owner Information Name: Antero Resources Piceance Corporation Address: 1625 17th Street, Suite 300 Denver, CO 80202 Facility Contact: Location: (303) 357-7341 This SPCC Plan covers numerous onshore production facilities located in Garfield County. The facilities are shown on maps provided with this plan. 8 May 2008 Antero Resources Piceance Corporation Spill Prevention, Control, and Countermeasure Plan Oil Production Facilities 2.1.1 Facility Layout Details for each facility covered by this plan are provided in Appendix A. In general, the physical layout of a production facility consists of one or more 300 barrel (bbl) welded steel above ground storage tanks (AST) containing hydrocarbon condensate, one or more 300 bbl tank. for storing produced water, one or more oil/water separators, one scrubber unit, one combustion unit and several wellheads. The wellheads and all the production equipment are connected with buried or aboveground steel flowlines. Each facility occupies a cleared area that includes the secondary containment areas surrounding tanks, as well as an earthen berm surrounding the perimeter of the facility comprising the wellhead, meter houses, access road, oil/water separators, combustion unit, and vehicle tum - around area. Runoff/drainage across uncontained portions of the sites is not anticipated to come into contact with hydrocarbons. Visual inspections of the entire location are performed by the pumper each time they are on site, as described in Section 2.3.2. 2.1.2 Tanks, Piping and Equipment The hydrocarbon condensate tanks, produced water tanks, separators, and heater treaters are considered bulk storage tanks/containers under the SPCC regulations. All condensate and produced water tanks are cylindrical with stationary roofs built in accordance with API Specification 12F design. All enclosed tanks are equipped with gas vents to relieve any pressure that might build up inside the tank, and are also equipped with vacuum protection that prevent over or under pressuring of the tanks. The tanks have been sized to provide sufficient capacity to prevent overfilling and when multiple tanks are present they are equipped with equalizing lines to prevent overfilling. Tanks are gauged daily to monitor level to ensure that sufficient tank capacity is available. As described in Section 2.3.2, tanks are visually inspected on a regular basis for leaks, corrosion, and any other malfunctions or deterioration. The equipment materials and construction and associated piping are compatible with the fluids stored and storage conditions such as pressure and temperature. Antero Resources' pads include multiple wells and each pad has the potential to have additional wells added. Therefore, the tanks and equipment associated with adding a well to a pad have been included in this SPCC Plan to address temporary oil storage that may be present at a site. Antero Resources drilling, well completion and testing activities are all pit -less operations to minimize long-term impacts to the environment. During these activities, multiple large tanks (up to 600 bbls) are placed on site to allow for frac water and flowback water storage. Both the frac and flowback water contain hydrocarbons. The frac and flowback tanks, when on site, are visually inspected on a regular basis for leaks, corrosion, and other signs of deterioration. These tanks are also constructed and compatible with the fluids stored and storage conditions. Flowlines are buried and constructed of steel which is compatible with the materials being stored. Flowlines are powder coated and/or painted. 2.1.3 Containment Berms Lined corrugated steel berms are present at each tank battery to provide secondary containment for the condensate and produced water tanks. The storage volume of each bermed area is large enough to contain the entire capacity of the largest single container in the secondary containment May 2008 9 Antero Resources Piceance Corporation Spill Prevention, Control, and Countermeasure Plan Oil Production Facilities plus sufficient freeboard to allow for precipitation. In addition, earthen berms around the perimeter of each of the facilities, provides secondary containment for condensate and produced water loading and unloading activities and separators. Should a release occur, the earthen berms will prevent migration of the spilled material away from the site and allow Antero Resources to control and mitigate the release in a timely and efficient manner. The earthen berms around the perimeter of each facility also provides secondary containment for any temporary tanks that may be present due to well drilling, completion or testing activities. The volume of the perimeter earthen berms is large enough to contain the entire capacity of the largest tank plus sufficient freeboard to allow for precipitation. The worst case scenario for release of oil is the loss of contaimnent of the largest tank at a particular facility due to rupture. This would result in the release of the entire capacity of the tank into the secondary containment over a very short time frame (less than one hour). In this scenario, oil would be contained within the lined constructed steel secondary containment, and the spill response and notification procedures provided in the Emergency Response Plan (Appendix 13) would be implemented. Another possible worst case scenario would be the release of condensate during truck loading activities. In this case the condensate would be contained by the earthen berms surrounding the site. In the unlikely event a berm is breached, oil would flow from the facility in the direction shown on the relevant facility diagram included in Appendix A. 2.1.4 Site Specific Facility Diagrams Site specific facility diagrams are included in Appendix A with the following detail and location information: • Process equipment, • Fixed aboveground storage tanks. • Direction of surface water runoff. • Completely buried and bunkered tanks (including USTs covered under 40 CFR 280 or 281). • Drum and portable container storage areas. • The contents and material of construction of all containers. 2.1.5 SPCC Plan Development Tables Site specific SPCC plan development tables were prepared at each facility included in Table 1. The development tables were created to standardize SPCC site inspections and maintain a database of information including but not limited to: • General facility information • Facility property information • Tank information • Surrounding drainage • Process Equipment • Comments • Containment/loadout information • Failure information outside of containment SPCC plan development tables can be found in Appendix A. May 2008 10 Antero Resources Piceance Corporation Spill Prevention, Control, and Countermeasure Plan Oil Production Facilities 2.2 General Requirements 2.2.1 Discovery, Response and Cleanup of Releases Inspections of facilities are routinely conducted as described in Section 2.3.2. In addition, employees are trained in the appropriate operation and maintenance of equipment and to look for, report and clean up releases as described in Section 2.5.1. All recovered materials are disposed of in accordance with all applicable federal, state and local laws and regulations as described in Section 2.4.1. 2.2.2 Notification Contacts The list of individuals and organizations to contact should a release occur is provided in Antero's Oil Spill Contingency Plan, a copy of which is provided in Appendix B. 2.2.3 Notification Forms Appendix C has the appropriate forms which must be completed prior to reporting a spill. These forms will help remind the operator of the procedures which must be followed and the information which must be furnished. 2.2.4 Response Plan General information on the response to, and reporting of, oil discharges can be found in Section 2.4 of this plan. Detailed information can be found in Antero's Oil Spill Contingency Plan, a copy of which is provided in Appendix B. This plan describes procedures that will be used under various emergency scenarios, including when an oil discharge occurs. The plan is also designed to address releases from areas such as flowlines where secondary containment is not practical. Reporting requirements and contact information is provided in the Oil Spill Contingency Plan. 2.3 Routine Facility Operations, Inspections and Maintenance Antero Resources's oil spill prevention program is described in this section of the SPCC plan and includes routine facility operations, periodic inspections and maintenance activities. It addresses all routine activities associated with the oil production facilities as required by 40 CFR 112.7 and 112.9. 2.3.1 Facility Operations All production equipment is operated to prevent and contain spills. Load line and drain valves are maintained in a closed position when not in use and loadouts are contained within the secondary containment structures. The facility is visited daily by the pumper, who gauges the fluid level in each tank and arranges for offloading of produced fluids when the inventory approaches the tank capacity. Fluid levels are not allowed to exceed 80 percent of tank capacity. The pumper also performs a visual inspection of all above ground vessels, separators, lines, tank hatches, valves, and secondary containment features to promptly identify and respond to leaks or other mechanical issues as described in Section 2.3.2. May 2008 11 Antero Resources Piceance Corporation Spill Prevention, Control, and Countermeasure Plan Oil Production Facilities Tank truck Ioading/unloading occurs at all the facilities covered in this plan. The condensate and produced water tanks are connected to one or more loadout points contained within the tank's secondary containment berms. Trucks used to offload condensate and produced water are positioned adjacent to the lined secondary contaimnent structures and are attended by the pumpers during all loading and unloading activities. The trucks and all loading activities are contained by the facility perimeter earthen berms. The maximum volume of oil that could be released from overfilling a truck is approximately 130 bbl. All loading and unloading activities are conducted by qualified contract personnel who are trained in proper loading and spill prevention techniques and procedures. Pumper truck personnel inspect tank truck and transfer lines including drains and outlets on the tank trucks prior to filling and before departure to ensure that there are no leaks or discharges. If necessary, truck personnel tighten, adjust, or replace equipment that is leaking. Premature vehicular departures are prevented with a manual air brake system and oversight. 2.3.2 Facility Inspection Program Tanks at production batteries are visited and gauged daily. Pumpers are trained to look for and report any leaks. In addition, each week a complete inspection of each facility is conducted and documented. The weekly inspection includes review of all above ground equipment, tanks, valves, hatches, and lines; the site drainage system; and the entire tank battery, including the area within the containment structures and earthen berms. Specifically, each storage vessel, separator, and miscellaneous equipment is visually inspected for deterioration and maintenance needs, including the foundation and support of each tank/container located on or above the ground surface. The inspection also includes visual check of facility transfer equipment including transfer piping and valves, drip pans, pumping well polish rod stuffing boxes, tanks, separators, heater -treaters, valve glands and bodies, pipe supports, and bleeder and gauge valves. Inspection of conditions associated with buried flowlines is accomplished by observing the ground surface above the lines for evidence of leaks on a routine basis. Observations made by the pumper are recorded on weekly inspection forms, which are stored at the Rifle Field Office and the corporate office in Denver. A copy of the weekly inspection form is provided in Appendix D. Mechanical integrity and spill -related issues are addressed as they are identified. In addition to equipment, the entire tank battery, including the area within the secondary containment structures and earthen containment berms, is visually inspected weekly. Site drainage systems such as drainage ditches, road ditches, and intermittent creeks in the vicinity of the facility are inspected for accumulations of oil. Rainwater and other precipitation that accumulates within the berm is either allowed to evaporate, infiltrate into underlying soil, or is removed using a vacuum truck. Excess rainwater removed by the vacuum truck is either returned to storage for use in hydraulic fracturing operations or transported for offsite disposal at a permitted non -hazardous disposal facility. No drains are present in the secondary containment structures or earthen berms. A discharge of rainwater from the secondary containment sturctures cannot occur unless the structure fails or is breached. Oil accumulating within the secondary containment area is removed using absorbent pads or is removed with excess rainwater using a vacuum truck as described above. Accumulated oil is not discharged outside of the secondary containment areas. Evidence of hydrocarbon spills are noted and remediated as appropriate as described in Section 2.4. May 2008 12 Antero Resources Piceance Corporation Spill Prevention, Control, and Countermeasure Plan Oil Production Facilities 2.3.3 Maintenance Program Antero Resources has a robust maintenance program aimed at eliminating releases of oil and minimizing unplanned downtime. Preventative maintenance on mechanical equipment is performed according to manufacturer recommendations to ensure proper operation and elimination of leaks. Any items requiring maintenance that are identified by visual inspections of the facilities are addressed by either Antero Resources mechanical staff or outside contractors. Equipment repairs are made in accordance with the relevant codes and industry standards. Flowline maintenance is performed on an as -needed basis by qualified personnel. If flowline failure occurs, the affected section of line is replaced with wrapped/coated steel pipe. 2.4 Response and Reporting Information Detailed spill reporting and response procedures are provided in the Emergency Response Plan included in Appendix B. The specific response activities taken will depend on the size and nature of the release. 2.4.1 Spill Response — Generally, each Antero employee and contractor is responsible for taking any immediate steps necessary to respond to a spill or release noted during a site visit. If a spill is discovered, the employee/contractor is instructed to isolate or shutdown the source of the release, either by shutting in the well, closing valves to the affected tank or other production vessel, or taking other actions deemed appropriate. After the source of the spill has been abated, the employee/contractor will contact the Incident Commander to report the event. The contact list included in the Emergency Response Plan and Oil Spill Contingency Plan provides the names of the primary and secondary personnel accountable for oil spill prevention and facility response. The contact list also includes important agency numbers. In general, recovered fluids are either returned to the production tank for eventual sale, used as frac fluid or recovered using a vacuum truck and transported offsite for disposal at a permitted commercial disposal facility. Hydrocarbon impacted soil is placed in a lined containment area, allowed to dry and tested to confirm no residual hydrocarbon contamination of concern. Upon receipt of acceptable analytical results, the soil is used onsite. 2.4.2 Spill Reporting As described in the Emergency Response Plan and the Oil Spill Contingency Plan, the Incident Commander will be notified in the event of a release. Notification forms are provided in Appendix C. These forms are designed to assist in providing information in the event of a discharge/release/spill. The forms will help document the event, identify information that needs to be obtained, and list site specific information. Depending on the size and site conditions of the spill, the Incident Commander may have to report the release to various state and federal regulatory agencies. The following paragraphs summarize the notification requirements for various regulatory programs. The reporting requirements for spills under the Clean Water Act, Colorado Water Pollution Control Act, and the Comprehensive Emergency Response, Compensation, and Liability Act (CERCLA) are as follows: 1. If a spill threatens waters of the State of Colorado (causes a sheen or film on surface water or staining of adjoining shorelines), the spill must be reported to the National May 2008 13 Antero Resources Piceance Corporation Spill Prevention, Control, and Countermeasure Plan Oil Production Facilities Response Center, Colorado Department of Public Health and Environment (CDPHE) and the appropriate Local Emergency Response Committee (LEPC) immediately. The reporting requirements for spills from COGCC-regulated facilities are: 1. If the spill is less than 5 bbl and it does not threaten a residence, occupied structure, livestock or waters of the State of Colorado, it is not reportable to COGCC. 2. If a spill threatens a residence, occupied structure, livestock or waters of the State of Colorado, the spill must be reported to COGCC immediately. 3. If the spill is greater than 5 bbl (210 gallons) but less than 20 bbl, it must be reported to COGCC within 10 days. 4. If the oil spill exceeds 20 bbl (840 gallons), it must be reported to COGCC within 24 hours. In addition to the spill reporting requirements listed above, if a spill that threatens waters of the State occurs on land owned by Bureau of Land Management (BLM), it is reportable to BLM. Similarly, if a spill threatens fish or wildlife, it must be reported to the U.S. Fish and Wildlife Service. 2.5 Spill Response Training 2.5.1 Annual Training Antero Resources and its contractors provide the following minimum training to oil -handling personnel: • Operation and maintenance of equipment to prevent oil discharges; • Oil discharge procedure protocols; • Applicable oil spill prevention (State & Federal) laws, rules, and regulations; • General facility operations; and • The contents of the facility SPCC Plan. Training is conducted prior to assignment of job responsibilities and then again annually. Training includes oil spill prevention, SPCC Plan requirements, and federal and state pollution prevention and spill reporting/response requirements. 2.5.2 Discharge Prevention Briefings The facility conducts discharge prevention briefings for oil -handling personnel at least once a year to assure adequate understanding of the SPCC Plan for the facility. At a minimum, this is conducted via annual SPCC and spill response refresher training describing the contents of the SPCC regulations and plans, spill response techniques, and a review of federal and state spill reporting requirements. These briefings also include discussion of potential discharges or component failures and precautionary measures. If a spill has occurred, Antero Resources will also summarize the spill events and the measures implemented to prevent future releases. May 2008 14 Antero Resources Piceance Corporation Spill Prevention, Control, and Countermeasure Plan Oil Production Facilities 2.5.3 Training Records Copies of training and discharge prevention logs can be found in Appendix D. Training records and Discharge Prevention Briefing logs are maintained for a minimum period of three (3) years at the Rifle Field Office. Each contractor organization providing oil -handling personnel maintains training records for its employees in its home office.

The company owns and operates numerous well pads that include tank batteries. The tank batteries generally consist of one or more 300 barrel above ground condensate storage tanks, production water storage tanks, and oil/water separators. Each tank battery has secondary containment per the SPCC plan. Multiple well heads at each pad are tied to tank batteries by flowlines. The flowlines are typically short. Isolation valves are periodically located along the lines. Most flowlines and consolidation lines are belowground and lack secondary containment. The company maintains an inspection and maintenance program to notice and prevent leaks from lines. All field operation personnel are familiar with the location of spill response equipment and response strategies, and with the SPCC and Oil Spill Contingency Plans. They receive annual training in the deployment of response material and handling of hazardous waste (HAZWOPER). Sufficient equipment to respond to the majority of oil discharges is kept at the Antero Resources Field Office and is accessible 24 -hours a day to field operation personnel.

Signature Date Name Title 2.0 INTRODUCTION 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 and oil and gas sites that disturb between one and five acres. This Stormwater Management Plan (SWMP) was prepared for Antero Resources (Antero) to be used for the Piceance Basin Gravel Trend Drilling 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 Drilling 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.

Other foremen or designated personnel may also assist in stormwater inspections and maintenance of records. Overall, the SWMP Team is responsible for: 2 072 V • 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 natural gas mineral rights in the Piceance Basin, Garfield County, Colorado. Antero's Piceance Basin Gravel Trend Drilling Program Area lies within Township 6 South, and Ranges 92 West and 93 West. Individual pad sites within the permitted area range from approximately 3/4 acres to three acres in size. The permitted area also includes field and site-specific access roads and pipelines. A topographic map of the project area is provided as Figure 2. 4.2 Sequence of Major Activities The overall development of natural gas pad sites is generally accomplished in three distinct work phases: development, production and abandonment. The work completed and sequences of events for each phase are briefly discussed below. Approximately 3/4 acres to three acres of surface terrain are disturbed during the construction of a new pad site. The construction phase includes the following sequence of activities: pad construction, well drilling, well completion, gas flowline installation, access road building, and well pad reclamation. The production phase includes the operation and maintenance activities during natural gas production. The typical equipment on a pad site during the production phase consists of a wellhead, a separation unit, and one or more 300 -barrel (typical) capacity aboveground tanks for condensate (if needed). Gas wells in the field are projected to produce for approximately 20 to 30 years. When the natural gas production of a well is exhausted it will be abandoned. Well abandonment includes plugging and capping the well and removal of all surface equipment. The pad area will be reclaimed by contouring disturbed soils to conform to the surrounding terrain. Gas activity types requiring ground surface disturbance include: a new drill site, a facility site, a plugged and abandoned (P&A) site, and an excavation/other site as well as pipeline construction and access roads. Each of these types is described as follows: 3 • A new drill site includes pad construction, well drilling, well completion, gas flowline installation, access road building and well pad reclamation. Pad reclamation is accomplished by backfilling the reserve pit (if applicable), contouring disturbed soils to conform to the surrounding terrain, replacing the stockpiled top soil, and seeding of disturbed soil areas in order to reestablish coverage vegetation. • A facility site includes pad construction, tank and sump installation (if applicable), gas flowline installation, access road building and pad reclamation. Pad reclamation is accomplished by contouring disturbed soils to conform to the surrounding terrain, replacing the stockpiled top soil, and seeding of disturbed soil areas in order to reestablish coverage vegetation. • A P&A site includes well abandonment, flowline re-routing or abandonment, access road decommissioning, and removal of all oilfield operations from the pad site. Pad reclamation is accomplished by contouring disturbed soils to conform to the surrounding terrain and seeding of disturbed soil areas in order to reestablish coverage vegetation. • An excavation/other site includes excavation for a variety of reasons. Excavation areas will be reclaimed by backfilling and contouring the disturbed area to conform to the surrounding terrain and seeding of disturbed soil areas in order to reestablish coverage vegetation. • Pipelines connect pad sites to other gathering operations within the basin. Pipeline connections are regularly maintained, added to, or repaired. These sites are included in this SWMP. Pipeline maintenance can include excavation, backfilling, and re -contouring the disturbed area, as listed above. Access roads provide access to the drill sites, pad sites, pipeline connections, facility sites, excavation sites, and P&A sites listed above. Roadwork construction and maintenance is included in this SWMP for these access roads. Road reclamation is accomplished by contouring disturbed soils to conform to the surrounding terrain, replacing the stockpiled top soil, and seeding of disturbed soil areas in order to reestablish coverage vegetation. For stormwater regulation purposes, construction sites have been divided into the following stormwater stages: Active, Completed, and Final Stabilization. Details regarding the stormwater stages are provided later in Section 8.2 of this plan. 4.3 Area of Disturbance The total field wide area of disturbance is approximately 95 acres. The site-specific areas of disturbance are identified on the site-specific database site maps; specific inspection forms; and history reports. (Appendix B). 4.4 Soil Description Soils in the project area consist of Arvada-Torrifluvents-Fleldt, Potts- lldefonso complex, Potts loam, Olney loam, Arvada loam, and Wann sandy loam. The elevation for these soil types range 4 from 5,000 feet to 9,500 feet above mean sea level (amsl). The slopes typically range from 1 percent (%) to 50 percent. A brief narrative of each soil type found in the Piceance Basin Gravel Trend Area is as follows: Arvada—Torrifluvents—Heldt, I% to 20% slopes — is a deep, well drained to somewhat poorly drained, on benches, terraces, alluvial fans, and flood plains. The surface layer typically consists of loam, clay loam, and sandy loam, stratified with sand gravel, or cobbles. Potts—Ildefonso complex, 12% to 25% slopes — is formed on mesas, alluvial fans, and sides of valleys. The native vegetation mostly consists of wheatgrass, needleandthread, and sagebrush. The permeability of the Potts soil is moderate, and the available water capacity is high. Runoff rate is medium, and the hazard of water erosion is moderate. The permeability of the Ildefanso soil is moderately rapid, and the available water capacity is low. Runoff rate is medium, and the hazard of water erosion is moderate. Elevations range from 5,000 feet to 6,500 feet amsl. Potts loam, 6% to 12% slopes — is formed on mesas, benches, and sides of valleys. The native vegetation mostly consists of wheatgrass, needleandthread, and sagebrush. The permeability is moderate, and the available water capacity is high. Runoff rate is medium, and the hazard of water erosion is severe. Elevations range from 5,000 feet to 7,000 feet amsl. Olney loam, 6% to 12% slopes — is a deep, well drained; moderately sloping to rolling soil and is on alluvial fans and sides of valleys. The soil is formed in alluvium derived primarily from sandstone and shale. Typically, the surface layer is grayish brown loam about 12 inches thick. The subsoil is grayish brown and light gray sandy clay loam about 21 inches thick. The substratum is light gray gravelly sandy clay loam and very gravelly sandy loam to a depth of 60 inches. Permeability is moderate, and available water capacity is moderate. Arvada loam, I% to 3% slopes -- is a deep and somewhat poorly drained on terraces and bottom land in valleys. The soil is formed in alluvium derived primarily from sandstone and shale. Typically, the upper part of the surface layer is dark grayish brown fine sandy loam about 4 inches thick. The underlying material is mottled, light brownish gray fine sandy loam and the lower part coarse sandy loam. Permeability is moderately rapid and available water capacity is high. Wann sandy loam, 1% to 3% slopes — deep, well -drained, sloping soils on fans and high terraces. The area contains slopes of 1% to 3%. This soil is formed in highly saline alluvium derived from sandstone and shale. The surface layer typically is strongly to very strongly alkaline, pale brown loam about 3 inches thick. The subsoil is brown silty clay loam and the substratum is light brown or brown silty clay loam. Permeability is very slow. 4.5 Vegetation Description The well pads in the basin are primarily surrounded by low shrubs and brush rangeland, tall grass, short grass prairie land, sand dune complexes, and occasional crop land. Native vegetation land cover types include Gambel Oak, Elk Sedge, Aspen, Bromes, Pinyon, Juniper, Indian Rice Grass, Wheatgrass, Junegrass, Serviceberry, Bitterbrush, Sagebrush, Shadescale, Saltbrush, 5 Greasewood, and Yucca. Pre -disturbance ground cover varies from 40% to 90%. Specific vegetation data at each pad site are entered on the site-specific inspection forms. 4.6 Description of All Potential Pollution Sources The location and description of all potential pollution sources are provided in detail in Section 6.1 and summarized in Table 1. 4.7 Non-Stormwater Discharges The following is a summary list of non-stonnwater discharges which are allowed under the stormwater permit: • Discharges from emergency fire -fighting activities or a fire hydrant; • Landscape irrigation or return flow; ▪ Uncontaminated springs; • Construction dewatering; and Antero does not anticipate any non-stormwater discharges at the pad sites. 4.8 Receiving Waters The stormwater discharged may directly impact unnamed tributaries to, as well as Mamm Creek, Last Chance Ditch, Dry Creek, Dry Hollow Creek, Multa Trina Ditch, Divide Creek, and Canyon Ditch, and then will ultimately be received by the Colorado River. The majority of Antero's pads or access roads do not intrude or encroach on any wetland acreage. If a wetland is designated to be within a pad construction area, Antero will consult with the Army Corp of Engineers, as applicable. 5.0 SITE MAPS The site maps are kept in Antero's database. Antero's database is intended to manage and track all site-specific stormwater records for Antero. The database consists of current inspection forms with supporting visio map attachments. Maps are updated at every inspection interval and dated to show changes from one inspection to the next. For the purposes of this SWMP, the site-specific map infonnation required to be included in the SWMP (Appendix B) will actually be comprised of the Antero database. Pad construction site boundaries; ground surface disturbances; areas of cut and fill; storage areas for building materials, equipment, soil or waste; structural BMP locations; non-structural BMP locations (as applicable); locations of springs, streams, wetlands or other surface waters; wellhead locations; and other pertinent site -specifics are shown on maps attached to the site- specific SWMP Inspection Reportss (Appendix 13). Site-specific features may be hand -drawn. 6 Sl7 6.0 STORMWATER MANAGEMENT CONTROLS 6.1 Identification of Potential Pollutant Sources To identify, evaluate, and assess potential sources of stormwater runoff pollutants that may exist at a pad site, the following activities and pollutant sources were evaluated: • Disturbed and stored soils; • Vehicle tracking controls; • Management of contaminated soils; Loading and unloading operations; Outdoor storage activities; Vehicle and equipment maintenance and fueling; Dust or particulate generating processes or activities; • Routine maintenance activities; • On-site waste management practices; • Concrete truck washing; • Dedicated concrete and asphalt batch plants; • Non -industrial waste sources; and • Potential spills. 6.1.1 Disturbed and Stored Soils Disturbed soil and excavated materials will be stored on or next to the pad. Topsoil and other soils will be stockpiled separately and seeded. Excavation in sensitive areas may be conducted using special techniques as specified by the landowner/agency representative. Materials excavated will be utilized as backfill when practical. An exception may be excess rock generated by rock blasting excavation activities. In these areas, some select backfill materials may be required to protect the project area. Excess rock may be pushed into rock filter dikes, used in energy dissipation zones below culverts, constructed into rock check dams within grassed swales, or distributed over a portion of the project area. All cut slopes made in steep rolling terrain during construction will be re -graded and contoured to blend into the adjoining landscape and natural drainage patterns will be reestablished to as near pre -disturbance levels as possible. 7 ( 411): Temporary workspace areas will be restored to approximate pre -construction conditions. 6.1.2 Vehicle Tracking Controls Properly constructed and graveled roads provide the best off-site tracking control. Access road entrances adjacent to paved county roads are often graveled to prevent or minimize any off-site soil tracking from pad areas or access roads. In some instances, cattle guards are used to drop off caked mud before the vehicle exits the site area. In addition, minimizing site access, contractor education, and other sediment control BMPs as specified on the site-specific information forms will be utilized in Appendix B. 6.1.3 Management of Contaminated Soils If contaminated soils are excavated at an Antero site, additional BMPs will be employed to ensure containment of any stormwater runoff. In addition, stockpiles of contaminated soil will be removed from the site and disposed or landfarmed as soon as possible. 6.1.4 Loading and Unloading Operations The majority of loading and unloading activities occur during well drilling and well completion activities. Well drilling and completion surfactants, friction reducers, dilute hydrochloric acid, potassium chloride solutions, drilling mud, condensate, and other fluids are transported or unloaded directly into the well from trucks, on site tanks, and/or the reserve pit. Dry drilling mud components are contained in paper bags and are stacked on pallets, which are unloaded using a forklift or by hand. In the event of a spill, the SWMP material handling and spill prevention procedures will be followed (see Section 6.2.4). Other activities include unloading of drill pipe, completion pipe (casing), and natural gas line pipe, which are not potential pollution sources. 6.1.5 Outdoor Storage Activities The most common substances that are stored on a pad area are: 1) fuel and lubricants used by vehicles and construction equipment; 2) frac fluids (surfactants, friction reducers, hydrochloric acid, and potassium chloride) used during well completion procedures; 3) production water from the well; and 4) produced crude oil and condensates. A Iist of chemical products typically used at an Antero pad site is included as Table 1. 6.1.6 Vehicle and Equipment Maintenance and Fueling Antero does not fuel or maintain construction -related vehicles or equipment located within the Antero Piceance Basin Gravel Trend Drilling Program Area. 6.1.7 Dust or Particulate Generating Processes or Activities Dust and/or particulates generated from vehicle traffic on graveled access roads may produce fugitive emissions. Dust and particulate generation are highest during dry and hot times of the year. If dust from vehicle traffic on graveled access roads becomes significant, dust suppression procedures will be implemented that include road watering. 8 r 6.1.8 Routine Maintenance Activities Routine maintenance activities involving fertilizers, detergents, fuels, solvents and oils are not completed at the Antero pad sites. Herbicides will be applied annually in some areas to control noxious weeds. Herbicide application will always be conducted by certified and trained individuals, and with consideration for runoff potential to nearby surface waters. 6.1.9 On-site Waste Management Practices All waste from materials imported to the construction site are placed in appropriate containment and then removed for disposal/recycling to an appropriate licensed disposal/recycling facility. No waste materials will be buried, dumped, or discharged to waters of the state. 6.1.10 Concrete Truck Washing Concrete truck/equipment washing, including the concrete truck chute and associated fixtures and equipment, is not conducted within the Antero Piceance Basin Gravel Trend Drilling Program Area. 6.1.11 Dedicated Concrete and Asphalt Batch Plants No dedicated concrete or asphalt batch plants are located within the Antero Piceance Basin Gravel Trend Drilling Program Area. 6.1.12 Non -Industrial Waste Sources Cleanup of trash and discarded materials will be conducted as noticed. Cleanup will consist of patrolling the roadway, access areas, and general work areas in order to pick up trash, debris, scrap, or other discarded materials. All waste from materials imported to the construction site are placed in appropriate containment and then removed for disposaUrecycling to an appropriate licensed disposal/recycling facility. This also includes sanitary sewage facilities (typically portable), which will be placed, anchored, and maintained with proper care. 6.1.13 Potential Spills Spills or leaks will be handled by Antero personnel or contractors, according to the Antero's Piceance Area, Production Wells, Garfield County, Colorado Spill Prevention, Control and Countermeasure (SPCC) Plan. Antero personnel conduct discharge prevention measures, including procedures for routine handling of products. Loading and transfer issues are discussed in monthly safety meetings. Preventive maintenance is scheduled by the SWMP Administrator. As part of the preventive maintenance program, Antero personnel conduct monthly inspections for good housekeeping issues, operation and maintenance issues, and the condition of structural controls, specifically around tanks and containers. 9 Operators are trained in the safe handling of materials and spill discovery, response, and cleanup procedures during safety meetings. Emergency numbers are posted at the Rifle office, 792 Buckhorn Drive, Rifle, Colorado. In general, small spills will be handled by Antero persoimel. The SWMP Administrator or his designee will handle spills and emergencies. In most cases, an absorbent material is used to pick up the spill. The spill response equipment is also located at the Rifle office. In the situation of a larger spill, the SWMP Administrator or Operations Manager would be notified and a contractor would be called to respond to the spill. For the protection of spill response personnel, all drums, tanks, and other containers are clearly Labeled to identify contents, in the event of a spill. Materials handling is discussed in detail in Section 6.2.4 of this plan. 6.2 Best Management Practices (BMPs) BMPS for sediment and erosion control will be accomplished through a combination of construction techniques, vegetation and re -vegetation, administrative controls, and structural features. Typical configurations of structural controls discussed below and technical drawings with references are provided in a BMP Manual and Technical Drawings (Appendix C). BMP selection is guided by the criteria listed in Table 2 and Appendix B. Structural and non- structural BMPs are discussed in the following sections, and are summarized in Table 3. 6.2.1 Structural Practices for Erosion and Sediment Control Structural practices primarily include physical attributes of a pad site, access road or pipeline designed to reduce erosion and control stormwater or sediment movement. 6.2.1.1 Erosion Reduction and Control Construction of a pad requires the removal of vegetative cover and topsoil, thereby increasing peak flood flows, water velocity, and the volume of stormwater runoff. An increase in water runoff volume and velocity results in increased erosion. Erosion reduction and control will be accomplished by using all or combinations of various erosion control methods. These methods include, but are not limited to the following: • Diversion and control of runon water; • Diversion and control of runoff water; • Vegetation establishment and maintenance; and • Application and maintenance of mulches, blankets, tackifiers, tracking and contouring. Runoff control procedures that will be used to mitigate and reduce the erosive transport forces of stormwater during and after construction of a pad will include but will not be limited to the following: 10 LW' • Check Dams; Berms; • Culverts; • Culvert Protection; • Diversions; • Land Grading; • Mulches, with or without a tackifier; and • Erosion Control Blanket. Existing vegetation cover and topsoil are removed only where necessary for the operation of equipment and construction of the pad. Trees and large shrubs that are not cleared from the pad area will be protected from damage during construction by avoiding them with equipment. For example, the blade of a bulldozer will be in a raised position except for designated areas. Trees will be cut or trimmed only to facilitate clearing, grading, and safe installation of a pad. Trees outside the area of disturbance will not be cut, but may have overhanging limbs trimmed if necessary. Refer to Tables 2 and 3 for a list of all BMPs to be used throughout the Field Wide SWMP. Appendix C includes details and technical drawings on BMP installation and maintenance procedures. 6.2.1.2 Sediment Reduction and Control The reduction and control of sediment contained in stormwater runoff will be accomplished by the use of sediment containment systems. Sediment containment systems are hydraulic controls that allow the detention of suspended particles via gravity, filtering or entrapment. Sediment controls that will be used to mitigate and control sediments generated from the erosive transport forces of stormwater during and after construction of a pad will include but will not be limited to the following: • Silt Fence; • Straw Bales; • Wattles; and • Vehicle Tracking Pads (Cattle Guard). Refer to Tables 2 and 3 for a list of all BMPs to be used throughout the Field Wide SWMP. Appendix C includes details and technical drawings on BMP installation and maintenance procedures. 6.2.1.3 Detailed Structural and Administrative Site Management Practices 11 The following structural and administrative site management practices are expected to reduce, minimize and control erosion and sediment transport: in order to minimize disturbances associated with installation of pads, level and gently sloping terrain outside the construction project area will not be graded, except where necessary. • To prevent tracking of sediment mud and rocks onto public roads, portions of access roads may be graveled, as appropriate. Other means such as track pads/angular rock or cattle guards may be utilized if appropriate. • Silt barriers (e.g. wattles, silt fence, straw bales) will be installed as needed on down - gradient portions of project areas. • Side hill cuts (cut slopes) will be kept to a minimum to protect local resources while providing a safe and stable plane for the efficient and safe use of equipment. • Where conditions warrant, erosion control structures such as berms, diversion or culverts may be constructed to divert water away from project areas. These control structures will also reduce soil erosion along and adjoining areas disturbed during construction. • During construction near perennial streams, lakes or wetlands, the utilization of sedimentation basins, silt fence, straw bales may be considered in order to prevent suspended sediments from reaching down slope watercourses, streams, lakes or wetlands. • Where appropriate, staked straw bales or silt fence may be constructed adjacent to crossings to reduce potential sedimentation in streams or wetlands. • In areas that have steep slopes, water bars or runoff diversions may be installed. When used, water bars will generally begin and end in undisturbed ground at approximately a 2% slope. Culverts may be installed at a grade ranging from 2% to 5%. Inlet protection may include inlet aprons and rock armoring around the culvert perimeter while below grade inlet sumps may be installed to enhance sediment deposition. Outfall protection may include the use of a rock barrier to slow the discharge of runoff water. Culvert pipe or outfall protection will be extended to the toe of the slope on the discharge end. ▪ During the reclamation of a pad, all cut and fill slopes in steep terrain will be graded and contoured to blend into the adjoining landscape. Natural drainage patterns will also be reestablished. When possible cut and fill slopes will be constructed so they are no steeper than a 1 to 3 ratio. • Reclaimed pads may have a fence constructed around areas that have been seeded. These fences will be installed in order to keep livestock and vehicles off reseeded areas. 6.2,1.4 Implementation of Structural Practices 12 The following structural practices (sediment controls) may be utilized at disturbed areas: vegetative buffers, brush barriers, silt fences, straw bale barriers, water bars, sediment traps, sediment basins, or equivalent sediment controls. These sediment control structures will be installed so as to protect down slope surface waters, wetlands and roads from sediment flow due to runoff from a precipitation or snow melt event. All graded surfaces, walls, dams and structures, vegetation, erosion and sediment control measures and other protective devices identified in the site plan will be maintained, repaired, and restored as necessary. Table 3 contains a summary list of structural and non-structural BMPs. 6.2.2 Non -Structural Practices for Erosion and Sediment Control Erosion and sediment control can also be controlled via non-structural BMPs. Non-structural BMPs are BMPs that are not engineered as a stormwater barrier and are capable of limiting the amount of potential pollutants available to reach receiving water bodies. Non-structural BMPs can achieve the same effect as structural BMPs through erosion control, filtration trapping and the settling of sediment load within a perimeter. Antero has implemented non-structural practices for stormwater management into their pad site development, including Program Oversight, Construction Site Planning and Management, and Materials Management. Table 3 summarizes the details of such practices. Pad sites can include a slope to the reserve pit or a buffer zone of natural vegetation used as a non-structural BMP to inhibit sediment travel offsite and minimize the footprint of the pad. 6.2.3 Phased BMP Implementation The phases of construction or development and stormwater stages are linked to the implementation of structural and non-structural BMPs. For stormwater regulation purposes, construction sites have been divided into the following stormwater stages: Active, Completed, and Final Stabilization. Storrnwater controls to be used for each phase are listed in Table 2 and 3. Preconstruction and Active Construction During pre -construction, drilling, and other active construction, the focus will be primarily on containment type BMPs. An example would be a continuous berm to contain stormwater pollutants on site. During this phase, stormwater runoff is specifically controlled so as not to leave the pad site. Completed Sites 13 For completed sites, containment BMPs are generally removed and areas are re -seeded. These are less active construction periods and less attention is needed regarding runoff when reclamation types of BMPs are put in place to mitigate the potential pollutants. Final Stabilization Sites Permanent stormwater BMPs, such as culverts and check darns, will remain in place after final stabilization. Depending upon the type of site, the site terrain, and the phase of construction, different stormwater BMPs will be utilized. Various BMP options are listed in Table 2, and design specifications are shown in the BMP Manual & Technical Drawings (Appendix C). 6.2.4 Material Handling and Spill Prevention Hazardous materials and petroleum products used in construction of a pad include fuel and lubricants for construction equipment and vehicles; small quantities of paints and solvents; water or gel based frac fluids (surfactant, friction reducer, dilute hydrochloric acid, potassium chloride) used during well completion; produced water; and crude oil/condensate. Material Safety Data Sheets (MSDS) for materials to be used or that are produced, are maintained at Antero's Rifle, Colorado office. Additional information regarding material handling and spill prevention can be found in Antero's Piceance Area, Production Wells, Garfield County, Colorado SPCC Plan. 6.2.5 Dedicated Concrete or Asphalt Batch Plants Antero does not have or subcontract any dedicated concrete or asphalt batch plants for its pad site development or construction in the Piceance Basin Gravel Trend Drilling Program Area, nor will stormwater encounter concrete or asphalt batch plant activities. 6.2.6 Vehicle Tracking Control Antero will employ BMPs to minimize vehicle tracking. Further discussion on this topic is in Section 6.1.2 of this SWMP. 6.2.7 Waste Management and Disposal, Including Concrete Washout Waste disposal is further discussed in Sections 6.1.9 and 6.1.12 of this plan. Concrete washout does not occur at Antero's sites, and therefore, will not be a potential pollutant to stormwater. 6.2.8 Groundwater and Stormwater Dewatering Construction dewatering may take place on a limited basis at Antero sites. The permit allows for conditional discharge of construction dewatering to the ground (to infiltrate), however no groundwater from construction dewatering can be discharged as surface runoff or to surface waters. For large construction projects with planned dewatering activity, Antero will apply for a separate dewatering permit from the state, as required. 14 (k719 7.0 FINAL STABILIZATION AND LONG-TERM STORMWATER MANAGEMENT 7.1 Reclamation Unless otherwise directed by the landowner or a jurisdictional authority, rocks, cut vegetation, and other surface material temporarily stockpiled during construction will be redistributed as backfill on the project area. During reclamation, sediment BMPs will remain in use. Disturbed areas will be seeded using seed mixes appropriate to the location noted in Table 4, unless the landowner wishes to return the land to agricultural production. Local soil conservation authorities with the U.S. Natural Resources Conservation Service, surface owners and/or reclamation contractors familiar with the area may be consulted regarding the other seed mixes to be utilized. On terrain where drill seeding is appropriate, seed may be planted using a drill equipped with a depth regulator to ensure proper depth of planting. The seed mix will be evenly and uniformly planted over the disturbed area. Drilling will be used where topography and soil conditions allow operation of equipment to meet the seeding requirements of the species being planted. Broadcast seeding will occur on steep terrain and on areas where the cut vegetation and rocks were redistributed over a right-of-way. Seeding will be done when seasonal or weather conditions are most favorable according to schedules identified by the jurisdictional authority, reclamation contractor, or landowner. Whenever possible, seeding will be timed to take advantage of moisture, such as early spring or late fall, which will benefit from winter precipitation. Seed mixes will be planted in the amount specified in pounds (as noted in Table 4) of pure live seed per acre. No primary or secondary noxious weeds will be in the seed mix. The reestablishment of vegetative cover as well as watershed stabilization measures will be scheduled during the working season and before the succeeding winter. Re -vegetation will be accomplished as soon as practical following the reclamation of a pad, pipeline or road. Mulch will be laid down during re -vegetation as appropriate. The cut vegetation and rocks will act like mulch in the areas where they are applied. Where straw or hay mulch is applied, the mulch will be applied and crimped into the soil. The need for fertilizers will be determined in conjunction with the landowner. If fertilization is necessary, the rates of application will be based on site-specific requirements of the soil. A special condition exists for pad sites within crop lands. According to the CDPHE Stormwater Fact Sheet dated July 2007: When portions of an oil and gas site are restored to crop land in accordance with the COGCC rules, and returned to the control of the farmer following interim reclamation, permit coverage is no longer required for those areas, and it is not necessary for the oil and gas site to either stabilize or reassign permit coverage for the area restored to crop land. 15 When this condition exists for a pad site, inspections will be discontinued and the site will be removed from the stormwater construction permit program. 7.2 Post Construction Structural Measures Perrnanent water bars, culverts, trench plugs and/or other permanent structural measures may be installed on steep slopes and at wetland and stream crossing boundaries. After restoration and reclamation work is complete, required repairs to vegetation and erosion and sediment control BMPs will be completed as required. 7.3 Finally Stabilized According to stormwater regulations, "finally stabilized means that all ground surface disturbing activities at the site have been completed and all disturbed areas have been either built on, paved, or a uniform vegetative cover has been established with an individual plant and a density of at least 70 percent of pre -disturbance levels, and the vegetation cover is capable of providing erosion control equivalent to pre-existing conditions, or equivalent permanent, physical erosion reduction methods have been employed." A special condition exists for oil and gas pad sites regarding pavement. According to the CDPHE Stormwater Fact Sheet dated July 2007: Areas developed as stabilized unpaved surfaces as needed for operation of the facility after interim reclamation also qualify as "anally stabilized". The term "stabilized unpaved surfaces" includes dirt road surfaces and the portions of the well pad surfaces that cannot be revegetated due to operational necessity, but does not include slopes, ditches and other areas where revegetation is necessary. Stabilized unpaved surfaces must be prepared in such a way as to minimize erosion, such as preventing rill erosion on pad surfaces or roads. 8.0 INSPECTION AND MAINTENANCE PROCEDURES 8.1 Preventive Maintenance Preventing stormwater from passing through pad areas where contamination may occur is a key element of preventative maintenance. Another key element of preventative maintenance is the routine inspection and repair of erosion and sediments control structures. Regular cleaning of diversion ditches and other BMPs to keep them free of debris and sediment will be practiced. Spillways and culvert systems will also be routinely cleaned and inspected. These maintenance procedures will help to insure that the stormwater does not leave disturbed areas via unintended channels. The following preventive maintenance procedures will be implemented to reduce or eliminate potential stormwater contamination sources that may exist on a pad: 16 (41717 • Storage containers, fuel tanks, and equipment used during construction activities should be visually inspected routinely for obvious leaks. These inspections should be conducted by site and contractor personnel as they perform their routine duties; • Drums will be properly labeled so an enclosed substance can be quickly identified. OSHA -approved labeling and sign systems will be followed for all secondary containers; • Erosion damage to the berms, outfalls, silt barriers, collection channel, containment ponds, and any other erosion and sediment controls will be repaired as soon as practical; • Areas of stained soil will be inspected in order to identify the sources of the staining. Contaminated soil will be removed and properly disposed; • Energy dissipating material, such as riprap, cobbles or gravel will be placed, or existing materials will be utilized at the stormwater outfalls to prevent erosion damage. Barrow ditches should be free from vegetation and debris which may cause impounding of stormwater; and • Stormwater management structures will be cleared of debris and repaired when necessary; and surface runoff controls such as culverts, and ditches will be used to control runoff. 8.1.1 Good Housekeeping In accordance with BMPs that provide procedures to eliminate contamination, and direct, divert, and contain stormwater, Antero has implemented a number of housekeeping practices. These practices will help prevent soil sediment, trash, and toxic or hazardous substances from entering navigable waters. Housekeeping practices include regular cleaning, organization and maintenance of pad equipment and erosion and sediment control structures throughout the project. Areas where chemicals are stored and used at the project should be stored in buildings or containers where there is limited potential for stormwater contact. These areas include producing pads that typically consist of wellheads, separator units, dehydration units, and 300 -barrel capacity aboveground tanks. The following items will be addressed in order to maintain a clean and orderly pad during the development, production, and abandonment phases of work: • Inspect pad areas routinely; • Correct deficiencies noted during inspections; • Clean and maintain stormwater management structures and components; • Routine trash collection and proper disposal; 17 Familiarize employees and contractors with spill clean-up equipment and storage locations; and • Familiarize employees and contractors with good housekeeping procedures and pad pollution prevention procedures. 8.1.2 Material Storage The following good housekeeping practices will be followed at the material storage areas: • Storage containers will be stored away from direct traffic to prevent accidents. They will also have proper labels; • Dumpsters and trash receptacles will be enclosed in order to prevent the dissemination of refuse; • Storage areas will be kept free of refuse; • Chemical substances used at pads will be properly labeled and will have proper spill containment; and • Chemical substance containers will be clearly labeled with an MSDS kept on file. 8.1.3 Waste Removal All waste from materials imported to the construction site will be removed for disposal/recycling to an appropriate licensed disposal/recycling facility, including sanitary sewage facilities (typically portable). No wastes of imported materials will be buried, dumped, or purposely discharged to waters of the state. There are no other pollutant sources from areas other than construction areas. 8.2 Inspections Inspections will be conducted to document the status of erosion and sediment control structures and re -vegetation efforts. Inspection forms will document non-compliance conditions, including any uncontrolled releases of sediment or other contaminants, additional BMPs that are needed, or repair and maintenance issues. Required actions or modifications, as documented on the SWMP Inspection Report, will be implemented in a timely manner after the inspection. Routine inspections may be conducted at pad areas and along access roads and pipelines during all phases of work and after a precipitation -related event. All inspection observations will be recorded on the SWMP Inspection Report. The form provides a standardized format that will be completed during all inspections, and includes a signature line for the inspector to ensure compliance with the regulations. For stormwater regulation purposes, construction sites have been divided into stormwater inspection stages: Active, Completed, and Final Stabilization. Each of these stonnwater inspection stages is discussed below. Once a Completed Site is finally stabilized, it will be removed from this stormwater construction permit program. 18 A special condition exists for pad sites within crop lands, which is detailed in Section 7.1 of this plan. When pad sites are being returned to a farmer for agricultural usage, the sites may be removed from the stormwater construction permit program. Personnel responsible for inspections will be trained to evaluate stormwater management concerns, erosion and sediment control BMPs, and to evaluate pad and surrounding area vegetation. 8.2.1 14 -day Inspection/Active Stage The construction phase of work is classified as the Active stage, according to stormwater regulations. The inspection frequency is every 14 days during the Active stage and must be conducted within 24 hours after the end of any precipitation or snowmelt event that causes surface erosion. The access roads, pads, gathering lines and associated disturbed areas, and any stored materials that are exposed to precipitation will be inspected for evidence of, or the potential for pollutants that may enter the drainage system. Erosion and sediment control that are identified on the site- specific SWMP Inspection Report will be inspected to ensure that they are in good condition and operating properly. 8.2.2 Monthly Inspection/Completed Stage For sites or portions of sites that meet the following criteria, but final stabilization is not achieved due to a vegetative cover that has not become established, a thorough inspection will be conducted at least once every month, and post -storm event inspections are not required. This reduced inspection schedule is only allowed if: • All construction activities that will result in surface ground disturbance are completed; • All activities required for final stabilization, in accordance with the SWMP, have been completed, with the exception of the application of seed that has not occurred due to seasonal conditions or the necessity for additional seed application to augment previous efforts; and • The SWMP has been amended to indicate those areas that will be inspected in accordance with the reduced schedule. However, because slopes and other disturbed areas are not vegetated, erosion in these areas still occurs which requires maintenance activities such as regrading, erosion control blankets, and seeding of problems areas. As such, inspections must continue in order to address these situations. The SWMP for the site must be amended to indicate those areas that will be inspected at this reduced frequency. 8.2.3 Final Stabilization Stage When any access roads, pads, gathering lines and associated areas have reached final stabilization, site-specific areas and associated BMPs will be removed from the stormwater 19 (_W construction inspection routine. All temporary site-specific BMPs no longer required will be removed. 8.2.4 Winter Conditions Inspections will not be required where construction activities are temporarily halted because snow cover exists over the entire site for an extended period as long as melting conditions do not exist. The following information must be documented in the inspection record for use of this exclusion: dates when snow cover occurred, date when construction activities ceased, and date melting conditions began. 8.2.5 Precipitation Event Inspections Active pad site inspections will be conducted within 24 hours after a precipitation or snowmelt event that causes surface erosion. If no construction activities will occur at a pad site following a storm event, post -storm event inspections will be conducted prior to re -commencing construction activities, but no later than 72 hours following the storm event. Surface erosion generally occurs when precipitation or snowmelt results in surface water flow. 9.0 EMPLOYEE TRAINING Antero will inform and train employees who are involved with SWMP activities. Training will cover information and procedures contained in the SWMP and will be conducted on an as - needed basis. Personnel work responsibilities will be used to identify the appropriate attendees. Safety and environmental elements of the SWMP will also be covered. A Training Log (Appendix D) will be kept and updated on an annual basis. The following topics may be presented and discussed during SWMP training: • Introduction to CDPS Stormwater Permit; • Stormwater regulations; • Purpose of storrnwater permit; • Requirements of stormwater permit; • Components of the SWMP; • Identification of potential pollutant sources; • BMPs; • Preventative maintenance; • Good housekeeping; • Inspections and maintenance; and 20 60:47:1 . Record keeping. 10.0 RECORD KEEPING The following record keeping procedures will be implemented in order to provide accurate and complete documentation of events associated with the stormwater management program. Routine inspections will include the 14 -day, monthly, and post precipitation event inspections. Stormwater related inspection records, site maps, and diagrams will be also kept on file or in the Antero database. All stormwater related records will be filed and stored by Antero for a minimum of three years after each individual site has achieved final stabilization 11.0 SWMP REVIEW/CHANGES Antero will amend the SWMP whenever there is a significant change in design, construction, operation, or maintenance, which has a significant effect on the potential for the discharge of pollutants to water of the state, or if the SWMP proves to be ineffective in achieving the general objectives of controlling pollutants in stormwater discharges associated with pad activities. The SWMP is considered a "living document". 21 Colorado River '4 mi. 1 :e w0 an 0 0 CIzuJ DRAINAGE FLOW DIRECTION 1 I STRWA.

Prepared for: Antero Resources 792 Buckhorn Drive Rifle, CO 81650 Prepared by: WestWater Engineering 2516 Foresight Circle #1 Grand Junction, CO 81505 July 2009 1.0 INTRODUCTION 1.1 Project Description At the request of Antero Resources (Antero), WestWater Engineering (WWE) has prepared an Integrated Vegetation and Noxious Weed Management Plan for the proposed Valley Farms Injection Wells D & F. Antero is proposing to convert existing well sites into injection wells, both of which lie approximately 1 mile south of Silt, Colorado in Sections 14 and 15, Township 6 South, Range 92 West (Figure 1). The project area lies within Garfield County, Colorado, and is located on private land. Access to the project area is currently available via County Road 331 (Dry Hollow Road), Mineota Drive, and private access roads. The primary use of the site and surrounding area is private residence, agricultural fields, wildlife habitat, and natural gas extraction/development. The general project area is currently undergoing rapid natural gas development including the drilling of wells, and the construction of pipelines, compressors, and access roads. 1.2 General Survey Information Mapped soil types, as published by the Natural Resources Conservation Service (NRCS), U.S. Department of Agriculture (USDA), were reviewed to determine the soil types and vegetation characteristics of the proposed injection wells and surrounding area (NRCS 2009). Field inspections of the project area were conducted by WWE biologists on July 8, 2009. WWE biologists surveyed the area in and around the proposed injection wells to identify vegetation communities and to search for, identify, and map noxious weed species. Vegetation types were determined through field identification of plants, aerial photography, and on -the -ground assessment of plant abundance visible during the survey. Identification of plant species was aided by using pertinent published field guides (Whitson et al. 2001, CWMA 2007, Kershaw et al. 1998, Weber and Wittmann 2001). Photographs were taken of the general project location, vegetation, terrain, and other specific biological findings. Locations of weeds and other features included in this report were recorded with the aid of a handheld global positioning system (GPS) receiver using NAD83/WGS84 map datum, with all coordinate locations based on the Universal Transverse Mercator (UTM) coordinate system in Zone 13. 2.0 LANDSCAPE SETTING 2.1 Vegetation Communities Vegetation communities around the project area are disturbed by agriculture, natural gas development, and nearby residential development. Vegetation consists of a mixture of agricultural fields and sagebrush shrublands with a grass understory. Widely scattered Orion - juniper woodlands lie on benches south of the project area. Pinon juniper woodlands are dominated by Utah juniper (Juniperus osteosperma) and occasional pinon pine (Pinus edulis) and are mixed with sagebrush (Artemisia tridentata ssp.), fortis, and grasses. Other vegetation observed in the area includes greasewood (Sarcobatus vermiculatus), rabbitbrush (Chrysothainnus nauseosus), Indian ricegrass (Achnatheruin hymenoides), kochia (Bassia prostrate), Russian thistle (Salsola ssp.), downy brome (Bromus tectorum), annual wheatgrass WestWater Engineering Page 1 of 16 July 2009 (Eremopyrurn triticeum), and crested wheatgrass (Agropyron cristatum). Agricultural fields north of both well pads D and F are heavily infested with Russian knapweed (Acroptilon repens). Bare ground is also present throughout much of the site due to natural gas development. The climate for the Colorado River valley is considered semi -arid with a wide range of temperatures and precipitation. The average annual precipitation in the region ranges between 10 and 14 inches, and temperatures range from about 95 degrees F in the summer months to -5 degrees F during the winter months. 2.2 Soils Soil types include loams and sandy to gravelly loams that overlay broken shale derived from the Green River Formation. Soil types present in the project area are those commonly found along the Colorado River's floodplains. Mapped soil types, as published by the Natural Resources Conservation Service (NRCS), U.S. Department of Agriculture (USDA), were reviewed to determine the soil types and vegetation characteristics of the project site and surrounding property (NRCS 2009). Four soil types are found in the project area and include the following: 1. Potts loam with 6-12 percent slopes. Present at well pad D. 2. lldefonso stony loam with 25-45 percent slopes. Present on slope north of well pad D. 3. Arvada loam with 1-6 percent slopes. Present in agricultural land north of well pad D. 4. Olney loam with 6-12 percent slopes. Present at well pad F. 2.3 Terrain The project area lies south of the Colorado River on a terrace west of Dry Hollow. Terrain is relatively flat with elevations ranging from about 5,220 ft to about 5,640 ft. Benches and hills dominated by pinon juniper woodlands lie south of the project area. Natural gas exploration and development is resulting in landscape/watershed scale habitat fragmentation. The physical loss of habitat is due primarily to the increase in roads, well pads, pipelines, compressor stations, and other ancillary facilities required to produce and transport natural gas. Additionally, agricultural and grazing practices have altered vegetative composition in the area, and have further contributed to the introduction and/or spread of invasive species. 3.0 NOXIOUS WEEDS 3.1 Introduction to Noxious Weeds Noxious weeds are plants that are aggressive competitors when non-native to an area. Most have come from Europe or Asia, either accidentally or as ornamentals that have escaped. Once established in a new environment, they tend to spread quickly because the insects, diseases, and animals that normally control them are absent. Noxious weeds are spread by man, animals, water, and wind. Prime locations for the establishment of noxious weeds include roadsides, construction sites, areas that are overused by animals or humans, wetlands, and riparian corridors. Subsequent to soil disturbances, vegetation communities can be susceptible to WestWater Engineering Page 3 of 16 July 2009 infestations of invasive or exotic weed species. Vegetation removal and soil disturbance during construction can create optimal conditions for the establishment of invasive, non-native species. Construction equipment traveling from weed -infested areas into weed -free areas could disperse noxious or invasive weed seeds and propagates, resulting in the establishment of these weeds in previously weed -free areas. The Colorado Noxious Weed Act (State of Colorado 2005) requires local governing bodies to develop noxious weed management plans. Both the State of Colorado and Garfield County maintain a list of plants that are considered to be noxious weeds. The State of Colorado noxious weed list includes three categories. List A species must be eradicated whenever detected. List B species include weeds whose spread should be halted. List C species are widespread, but the State will assist local jurisdictions which choose to manage those weeds. The Garfield County Weed Advisory Board has compiled a list of 21 plants from the State list considered to be noxious weeds within the county (see Appendix A). Four of those weed species were found in, or near, the project area. The Garfield County Weed Advisory Board has duties to: 1. Develop a noxious weed list, 2. Develop a weed management plan for designated noxious weeds, and 3. Recommend to the Board of County Commissioners that identified landowners submit an integrated weed management plan for their properties. 3.2 Observations Eight Colorado State listed weed species are found in the project area, four of which are listed by Garfield County (Table 1 and Appendix A). Colorado State B listed weeds (four) observed in the project area were Russian knapweed (Acroptilon repens), musk thistle (Carduus nutans), redstem filaree (Erodiurn cicutarium), and houndstongue (Cynoglossurn officinale). Colorado State C listed weeds (four) observed in the project area were chicory (Cichorium in ybus), halogeton (Halogeton glomeratus), field bindweed (Convolvulus arvensis), and downy brome (Bromus tectorum). Of these State listed weeds, Russian knapweed, houndstongue, chicory, and musk thistle are listed by Garfield County. The heaviest infestations of Garfield County listed noxious weeds were found north of well pad D in an agricultural field (Photos 1 and 2). Russian knapweed was observed in this field from the toe of the slope below the pad to an irrigation ditch which runs east/west to the north of the pad. Chicory was also observed along the irrigation ditch north of the pad. Several smaller infestations of Russian knapweed were also observed north of well pad F (Figure 2). Additional invasive plants were found in the project are that are not listed by the State of Colorado or Garfield County but may be considered nuisance weeds. These plants can negate revegetation efforts and cause losses due to decreased seeding success and associated costs. The presence of these plants creates increased competition for resources by desirable seeded and native young plants. Plants in this category observed in the project area include kochia (Bassia prostrata), Russian thistle (Salsola spp.), and annual wheatgrass (Ererrropyrurrr triticeum). Kochia infestations were heavy along the access roads to the pads, in small nearby drainages, and along cut and fill slopes around the pads (Photo 3).

Superscript - Colorado State B or C list. 3.3 Integrated Weed Management Control of invasive species is a difficult task. Care must be taken to prevent damage to desirable plant species during treatments to prevent further infestations by other pioneer invaders. Weed management is best achieved through a variety of methods over a long period of time including, inventory (surveys), direct treatments, prevention through best management practices, monitoring of treatment efficacy, and subsequent detection efforts. Weed management is often reserved to "control" of existing species and prevention of further infestations (existing and novel species) rather than eradication. After successful and effective management, decreases in infestation size and density can be expected, and after several years of successful management practices, eradication is sometimes possible. 3.4 Prevention and Assessment of Noxious Weed Infestations Weed management is costly and heavy infestations may exceed the economic threshold for practical treatment. Prevention is especially valuable in the case of noxious weed management. Several simple practices should be employed to prevent most weed infestations. The following practices should be adopted for any activity to reduce the costs of noxious weed control through prevention. The practices include: • Prior to delivery to the site, equipment should be thoroughly cleaned of soils remaining from previous construction sites which may be contaminated with noxious weeds. • If working in sites with weed -seed contaminated soil, equipment should be cleaned of potentially seed -bearing soils and vegetative debris at the infested area prior to moving to uncontaminated terrain. • All maintenance vehicles should be regularly cleaned of soil. • Avoid driving vehicles through areas where weed infestations exist. WestWater Engineering Page 8 of 16 July 2009 Assessment of the existence and extent of noxious weeds for an area is essential for the development of an integrated management plan. This report provides an initial assessment of the occurrence of noxious weeds for the project area. In order to continue effective management of noxious weeds, further inventory and analysis is necessary to 1) determine the effectiveness of the past treatment strategies, 2) modify if necessary the treatment plan, and 3) detect early any infestations of new species or locations and thus more economical treatments. 3.5 Treatment and Control of Noxious Weed Infestations Invasive and noxious weeds commonly occur along ditches, creek corridors and adjacent drainages (especially in riparian areas), abandoned fields, and disturbed areas such as well pads, pipeline routes, and roadsides. Control methods for the four Garfield County listed noxious weed species found in the project area are described in Table 2. Included in Table 2 are weed life cycle type and recommended control methods for each weed species. Table 2. Weed Treatment Methods Common Name* .: Scientific Name ;. USDA Symbol '..

Superscript - Colorado State B or C list. *'t Type: A = annual; B = biennial; CP = creeping perennial; N = perennial 3.6 Recommended Treatment Strategies It is important to know whether the target is an annual, biennial, or perennial to select strategies that effectively control and eliminate the target. Treatment strategies are different depending on plant type, which are summarized in Tables 3 and 4. Herbicides should not always be the first treatment of choice when other methods can be effectively employed. WestWater Engineering Page 9 of 16 July 2009 Some weeds, particularly annuals and biennials, can develop resistance to herbicides. The ability to quickly develop immunity to herbicides, especially when they are used incorrectly, makes it imperative to use the proper chemicals at the correct time in the specified concentration according to the product label. Most misuse is centered on excessive application, either in frequency or concentration. This results in mostly top kill and resistant phenotypes. Table 3. Treatment Strategies for Annual and Biennial Noxious Weeds Target: Prevent Seed Production 1. Hand grub (pull), hoe, till, cultivate in rosette stage and before flowering or seed maturity. If seeds develop, cut and bag seed heads. 2. Cut roots with a spade just below soil level. 3. Treat with herbicide in rosette or bolting stage, before flowering. 4. Mow biennials after bolting stage, before seed set. Mowing annuals will not prevent flowering but can reduce total seed production. fro Table 4. Treatment Strategies for Perennials Target: Deplete nutrient reserves in root system, prevent seed production 1. Allow plants to expend as much energy from root system as possible, do not treat when first emerging in spring, but allow growth to bud/bloom stage. If seeds develop, cut and bag if possible. 2. Herbicide treatment at bud to bloom stage or in the fall (recommended after August 15 when natural precipitation is present). In the fall, plants draw nutrients into the roots for winter storage. Herbicides will be drawn down to the roots more efficiently at this time due to translocation of nutrients to roots rather than leaves. If the weed patch has been present for a long period of time, another season of seed production is not as important as getting the herbicide into the root system. Spraying in fall (after middle August) will kill the following year's shoots, which are being formed on the roots at this time. 3. Mowing usually is not recommended because the plants will flower anyway; seed production should be reduced. Many studies have shown that mowing perennials and spraying the re -growth is not as effective as spraying without mowing. Effect of mowing is species dependent; therefore, it is imperative to know the species and its basic biology. Timing of application must be done when biologically appropriate, which is not necessarily convenient. 4. Tillage may or may not be effective. Most perennial roots can sprout from pieces only %z" — 1" long. Clean machinery thoroughly before leaving the weed patch. 5. Hand pulling is generally not recommended for perennial species unless you know the plants are seedlings and not established plants. Hand pulling can be effective on small patches but is very labor intensive because it must be done repeatedly. 3.7 Life Cycle and Management Calendars Best results in the control of Garfield County listed noxious weeds found in the project area can be achieved by following the recommended timetable presented in Table 5. Species not listed can be considered to have control timing similar to plants of the same type (annual, biennial etc.).

Regulations may require a Colorado licensed applicator. An applicator has the full range of knowledge, skills, equipment, and experience desired when dealing with tough noxious weeds. Reclamation farming services using multiple seed bin range drills and specialized related equipment is available and should be used for reclamation seeding projects. WestWater Engineering Page 11 of 16 July 2009 Common chemical and trade names may be used in this report. The use of trade names is for clarity by the reader. Inclusion of a trade name does not imply endorsement of that particular brand of herbicide and exclusion does not imply non -approval. Certified commercial applicators will decide which herbicide to use and at what concentration according to label directions. Landowners using unrestricted products must obey all label warnings, cautions, and application. concentrations. The author of this report is not responsible for inappropriate herbicide use by readers. 3.9 Best Management Practices -- Noxious Weeds Construction: The following practices should be adopted for any construction project to reduce the costs of noxious weed control and aid in prevention efforts. The practices include: • top soil, where present, should be segregated from deeper soils and replaced as top soil on the final grade, a process known as live topsoil handling; • wetland vegetation, if encountered, should be live handled like sod, temporarily watered if necessary, and placed over excavated sub -soil relative to the position from which the wetland sod was removed; • cut-off collars should be placed on all wetland and stream crossings to prevent back washing or draining of important aquatic resources; • in all cases, temporary disturbance should be kept to an absolute minimum; • equipment and materials handling should be done on established sites to reduce area and extent of soil compaction; • disturbances should be immediately reseeded with the recommended mix in the re - vegetation section; • topsoil stockpiles should be seeded with non-invasive sterile hybrid grasses, if stored longer than one growing season; • prior to delivery to the site, equipment should be cleaned of soils remaining from previous construction sites which may be contaminated with noxious weeds; and • if working in sites with weed -seed contaminated soil, equipment should be cleaned of potentially seed -bearing soils and vegetative debris prior to moving to uncontaminated terrain. In areas with slope greater than 3 percent, imprinting of the seed bed is recommended. Imprinting can be in the form of dozer tracks or furrows perpendicular to the direction of slope. When utilizing hydro -seeding followed by mulching, imprinting should be done prior to seeding unless the mulch is to be crimped into the soil surface. If broadcast seeding and harrowing, imprinting should be done as part of the harrowing. Furrowing can be done by several methods, the most simple of which is to drill seed perpendicular to the direction of slope in a prepared bed. Other simple imprinting methods include deep hand raking and harrowing, always perpendicular to the direction of slope. WestWater Engineering Page 12 of 16 July 2009 Herbicides: Annual and biennial weeds are best controlled at the pre -bud stage after germination or in the spring of the second year. The species identified in the survey are susceptible to commercially available herbicides. Selective herbicides are recommended to minimize damage to desirable grass. Herbicide use in any riparian zones should be restricted to formulations that are approved for such use. Non-selective aquatic glyphosate fonnulations (e.g., Rodeo®) can be used in riparian areas with little danger to the ground or surface water, but desired grasses, forbs, shrubs and trees are susceptible to damage by direct contact. Professionals or landowners using herbicides must use the concentration specified on the label of the container in hand. Herbicides generally do not work better at higher concentrations. Most herbicide failures observed by WIVE are related to incomplete control caused by high concentrations killing top growth before the active ingredient can be transported to the roots through the nutrient translocation process. Most herbicide applications should use a surfactant if directed on the herbicide label or other adjuvants as called for on the herbicide label. Grazing: Grazing should be deferred, in reclaimed areas, until the desired grass species are established. Mechanical: Due to the heavy infestations of Russian knapweed observed north of both well pads D and F, mechanical treatment is not highly recommended in these areas. Other weeds observed in the project area that occur on disturbed surfaces that could be easily accessed are more likely to show success after mechanical treatments. Such areas are ideal for mechanical control with a hand tool (shovel etc.) during infestation stages while numbers are relatively low and visibility is good. Alternative Methods: An alternative method, particularly where there is poor or destroyed topsoil, is the application of vesicular-arbuscular mycorrhizal fungi, typically referred to as AMF. These fungi, mostly of the genus Glomus, are symbiotic with about 80 percent of all vegetation. Endo-mycorrhizal fungi are associated mostly with grasses and forbs and could be helpful when reclaiming this project. In symbiosis, the fungi increase water and nutrient transfer capacity of the host root system by as much as several orders of magnitude (Barrow and McCaslin 1995). Over-the-counter commercial products, which are better adapted to coating seeds when re- seeding and treating roots of live seedling trees and shrubs at time of planting, come in powder form and are available from many different sources. Some also come in granular form to be spread with seed from a broadcast spreader. The best AMF products should contain more than one species. All Colorado State Forest Salida District tree and shrub plantings include the application of AMF. According to District Forester Crystal Tischler, "AMF is worth it" (Tischler 2006). Most, if not all, Coloradoepartment of Transportation re-vegetation/reseeding projects now require use of AMF and BioSol, a certified by-product of the penicillin manufacturing process composed primarily of mycelium. Compacted soils respond well to fossilized humic substances and by- products called humates. These humates, including humic and fulvic acids and humin were formed from pre -historic plant and animal deposits and work especially well on compacted soils when applied as directed. WestWater Engineering Page 13 of 16 July 2009 4.0 REVEGETATION — RECLAMATION 4.1 Project Area The project area is comprised of arid agricultural meadows, grass and shrubland rolling hills, and sparse foothill woodlands. Successful reclamation of the project area is dependent upon soil type and texture, slope gradient and aspect, proper weed control, available water, and revegetation with suitable plant species. Based on the soil types, terrain, and the presence of noxious weeds in the project area, successful reclamation is most likely if a seed mix of grasses and shrubs is used. The seed mix presented in Table 6 is recommended. The suggested seed mix is based on BLM recommendation for the elevation and vegetation type presently occurring in the project area (BLM 2008). For best results and success, the recommended grass mixture reseeding should be done in late autumn. The reseeding rate should be doubled for broadcast application (CNHP 1998). Preferred seeding method is multiple seed bin rangeland drill with no soil preparation other than simple grading to slope and imprinting and waterbars where applicable. Alternative seeding methods include, but are not limited to: • harrow with just enough soil moisture to create a rough surface, broadcast seed and re - harrow, preferably at a 90 degree angle to the first harrow; • hydro -seeding (most economical in terms of seed cost); and • hand raking and broadcast followed by re -raking at a 90 degree angle to the first raking. • These are not the only means of replanting the site. However, these methods have been observed to be effective in similar landscapes. After desired grasses are established and control of target weed species is successful, then shrubs, forbs, and trees can be planted without concern for herbicide damage. Few native forb seeds are available commercially as cultivars. Most are collected from natural populations. Native shrubs and forbs often do not establish well from seed, particularly when mixed with grasses. Past experience has shown that stabilizing the soil with grasses, accomplishing weed control, and then coming back to plant live, containerized woody species in copses has been the most cost effective method for establishing the woody species component of the plant community. For sites where soil disturbance will be temporary, grasses should be drilled after construction activities cease and the equipment is removed from the site. After two years of controlling weeds (with herbicides) and allowing the grasses to become established, forbs and woody species should be inter -seeded or hand -planted to increase the diversity and value of the reclamation plantings. 4.2 Reclamation Goals Interim and final reclamation measures shall be consistent with those outlined in 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.

Antero is proposing to convert existing well sites into injection wells, both of which lie approximately 1 mile south of Silt, Colorado in Sections 14 and 15, Township 6 South, Range 92 West (Figure 1). The project area lies within Garfield County, Colorado, and is located on private land. Access to the project area is currently available via County Road 331 (Dry Hollow Road), Mineota Drive, and private access roads. The primary use of the site and surrounding area is private residence, agricultural fields, wildlife habitat, and natural gas extraction/development. The general project area is currently undergoing rapid natural gas development including the drilling of wells, and the construction of pipelines, compressors, and access roads. 1.2 General Survey Information In preparation for developing the following report, WWE biologists performed field surveys and assessments of wildlife, wildlife habitats, and habitats for sensitive plant species on the proposed project area. WWE conducted surveys on July 8, 2009. The purpose of the surveys was to determine the wildlife and sensitive plant species that occupy the project area at varying periods during the year, and species that would potentially be impacted as a result of the proposed injection wells and operational activities. Factors considered include: 1) soil type and texture; 2) existing land management; 3) absence or presence of wildlife and plant species including raptors, sage -grouse, and other sensitive birds species; 4) special designations by Federal and State wildlife agencies; and 5) the existing natural vegetation community. This report provides written documentation that describes survey findings as well as recommended mitigation measures. 2.0 LANDSCAPE SETTING 2.1 Vegetation Vegetation communities around the project area are disturbed by agriculture, natural gas development, and nearby residential development. Vegetation consists of a mixture of agricultural fields and sagebrush shrublands with a grass understory. Widely scattered pifion- juniper woodlands lie on benches south of the project area. Pinon juniper woodlands are dominated by Utah juniper (Juniperus osteosperma) and occasional pinon pine (Pinus edulis) and are mixed with sagebrush (Artemisia tridentata ssp.), forbs, and grasses. Other vegetation observed in the area includes greasewood (Sarcobatus vermiculatus), rabbitbrush (Chrysothamnus nauseosus), Indian ricegrass (Achnatherum hymenoides), kochia (Bassia prostrata), Russian thistle (Salsola ssp.), downy brome (Bromus tectorum), annual wheatgrass (Eremopyrum triticeum), and crested wheatgrass (Agropyron cristatum). Agricultural fields north of both well pads D and F are heavily infested with Russian knapweed (Acroptilon repens). Bare ground is also present throughout much of the site due to impacts from development.

Py 9. 2C09 bms LL 9 N a The climate for the Colorado River valley is considered semi -arid with a wide range of temperatures and precipitation. The average annual precipitation in the region ranges between 10 and 14 inches, and temperatures range from about 95 degrees F in the summer months to -5 degrees F during the winter months. 2.2 Soils Soil types include loams and sandy to gravelly loams that overlay broken shale derived from the Green River Formation. Soil types present in the project area are those commonly found along the Colorado River's floodplains. Mapped soil types, as published by the Natural Resources Conservation Service (NRCS), U.S. Department of Agriculture (USDA), were reviewed to determine the soil types and vegetation characteristics of the project site and surrounding property (NRCS 2009). Four soil types are found in the project area and include the following: 1. Potts loam with 6-12 percent slopes. Present at well pad D. 2. Ildefonso stony loam with 25-45 percent slopes. Present on slope north of well pad D. 3. Arvada loam with 1-6 percent slopes. Present in agricultural land north of well pad D. 4. Olney loam with 6-12 percent slopes. Present at well pad F. 2.3 Terrain The project area lies south of the Colorado River on a terrace west of Dry Hollow. Terrain is relatively flat with elevations ranging from about 5,220 ft to about 5,640 ft. Benches and hills dominated by pifion juniper woodlands lie south of the project area. Natural gas exploration and development is resulting in landscape/watershed scale habitat fragmentation. The physical loss of habitat is due primarily to the increase in roads, well pads, pipelines, compressor stations, and other ancillary facilities required to produce and transport natural gas. Additionally, agricultural and grazing practices have altered vegetative composition in the area, and have further contributed to the introduction and/or spread of invasive species. 3.0 WILDLIFE AND PLANT SURVEYS 3.1 Background Information Descriptions of critical habitats for federally listed threatened, endangered, and candidate fish and wildlife species were reviewed in the Federal Register, U.S. Department of the Interior, U.S. Fish and Wildlife Service (FWS). Wildlife habitat (activities) maps, provided via the internet web by the Colorado Division of Wildlife's (CDOW) "Natural Diversity Information Source" (NDIS), were reviewed and incorporated into this report in reference to mule deer, elk, black bear, mountain lion, and state -listed threatened, endangered, and species of "special concern"(CDOW 2008a). A list of Birds of Conservation Concern (BCC) and their habitats was reviewed. This list is published by the FWS through a Memorandum of Understanding with the BLM and the U.S. Forest Service (USFS), which places high conservation priorities for BCC species (USFWS 2002). Not all of these BCC species occur regularly in Colorado, and some are present only as WestWater Engineering Page 3 of 15 July 2009 seasonal migrants. Of those known to breed in Colorado, only a portion are known or suspected to breed within the vicinity of the project area. Avian literature sources such as the "Birds of Western Colorado Plateau and Mesa Country" (Righter et al. 2004) and the "Colorado Breeding Bird Atlas" (Kingery 1998) were reviewed to determine the likelihood for species occurrence within the project area. Bird identification and taxonomic nomenclature are in accordance with that applied by the Colorado Breeding Bird Atlas Project (Kingery 1998). The determination of the presence/absence of suitable habitat for threatened, endangered, and "sensitive species" (TESS) plants was based on previous WWE observations of typical habitat occupied by BLM or USFS sensitive plants, the Colorado Natural Heritage Program (CNHP) Rare Plant Field Guide (Spackman et al. 1997), and locations of species documented in the CNHP statewide database. 3.2 Survey Methods A preliminary review of the project area, using aerial photography maps, was conducted to familiarize personnel with vegetation types and terrain and as an aid to help determine the likelihood of the presence of threatened, endangered, or sensitive wildlife and plant species. Field data, including general project location, boundaries, and reported features, were verified and/or recorded with the aid of a handheld global positioning system (GPS) receiver utilizing NAD83/WGS84 map datum, with all coordinate locations based on the Universal Transverse Mercator (UTM) coordinate system within Zone 13. WWE biologists conducted pedestrian surveys of the area to identify and locate wildlife species, wildlife sign (tracks, fecal droppings, and vegetation disturbance), vegetation communities, and wildlife habitats. Vegetation types were determined through field identification of plants, aerial photography, and on -the -ground assessments of plant abundance. Identification of plant species was aided by using pertinent published field guides (Whitson et al. 2004, Weber and Wittman 2001, CWMA 2007, Kershaw et al. 1998). Visual searches for raptor and other bird species nests were focused on cottonwood trees within a 0.25 mile distance from the well pads. Nest searches and bird identification were aided with the use of binoculars and song recognition, where needed. Photographs were taken of the general project location, surrounding vegetation, and terrain (Cover Photo). 4.0 RESULTS OF SURVEY 4.1 TESS Plant Species The occurrence and distribution of TESS plants are strongly influenced by geologic formations and the resulting soil types present in an area. Individual plant populations are scattered and are usually only comprised of a small number of individual plants. This is primarily a result of specific soil and moisture requirements of each species and the high variability in the distribution and surface exposure of the layers within the formation. Harrington beardtongue (Penstemon harringtonii) is the only TESS plant with the potential to occur in the vicinity of the proposed injection wells. This species occurs most oven in sagebrush shrublands, and less commonly, pinon juniper woodlands between 6,800 and 9,200 feet. Thus, the project area is outside the known range for Harrington beardtongue, and the terrain and soils do not appear suitable for any other species of TESS plants. WestWater Engineering Page 4 of 15 July 2009 4.2 Federal Listed Threatened, Endangered, Candidate Wildlife Species Two federally endangered fish species are known to occur in the Colorado River north of the project site. However, designated critical habitat for the federally endangered Colorado pikeminnow and razorback sucker lies downstream from the project area (Maddux et al. 1993). 4.3 State Listed Threatened, Endangered and Special Concern Wildlife Species WWE biologists determined that five state listed threatened, endangered, or special concern species may occur within the project area and are listed in Table 1 (CDOW 2008b).

Raptor species that are common to the area include Golden Eagle, Bald Eagle, Red-tailed Hawk, American Kestrel, Cooper's Hawk, Sharp -shinned Hawk, Northern Harrier, Long-eared Owl, and Great Horned Owl, The riparian corridors and shale cliffs existing in the project area are of sufficient height and density for tree and cliff nesting raptors, although very little suitable habitat lies within 0.25 miles of the proposed injection wells. WestWater Engineering Page 5 of 15 July 2009 Raptor species that are listed as BCC which may occur in the project area are listed in Table 2. In addition to the BCC list, six other species of raptors that could potentially be found nesting in the project area are also listed in Table 2. Table 2. Raptor species that may be present in the project area Common Name Scientific Name BCC Habitat & BreedingRecords Northern Harrier Circus cyaneus Y • Grassland, shrubland, agricultural arcas, and marshes. Nests in areas with abundant covera tall reeds, cattails, grasses) in grasslands and mgarshes. Also known to nest in high -elevation sagebrush. Cooper's Hawk Accipiter cooperii N • Cottonwood riparian to spruce/fir forests, including pifton/juniper woodlands. Nests most frequently in pines and aspen. Sharp -shinned Hawkstriates Accipiter N • High density young, or even -aged, stands of coniferous forest and deciduous forests of aspen or oak brush with small stands of conifers. Red-tailed Hawk ButeoN jamaicensis • Diverse habitats including grasslands, pifion-juniper woodlands and deciduous, coniferous and riparian forests. Nests in mature trees (especially cottonwood, aspen, and pines) and on cliffs and utility poles. Golden Eagle Aguila chrysaetos Y • Grasslands, shrublands, agricultural areas, piflon- juniper woodlands, and ponderosa forests. Prefers nest sites on cliffs and sometimes in trees in rugged areas. American Kestrelsparverius Falco Bubo N N • Coniferous and deciduous forests and open terrain with suitable perches. Nests in cavities in trees, cliffs and buildings. • Occupies diverse habitats including riparian, deciduous and coniferous forests with adjacent open terrain for hunting. Great Horned Owlvirginianus Long-eared Owl Asio otus N • Occupies mixed shrublands. Nests and roost in sites in dense cottonwoods, willows, scrub oak, junipers and dense forest of mixed conifers and aspens. Bald Eagle Haliaeetus leucocephalus Y • Generally nest near larger bodies of water that support fish populations. Nests in large trees and cliffs. No raptor nests were observed within 0.25 miles of the project area. No known Bald Eagle nest sites are located within the project area. CDOW records (NDIS 2007) indicate that Bald Eagle winter range and roost sites are located along the Colorado River, more than 0.3 miles north of the project area. 4.4.2 Birds of Conservation Concern (BCC) other than raptors In addition to the raptors discussed above, WWE biologists surveyed the project area for the presence of the sensitive BCC and their habitat that could be present in the project area. BCC habitat and nesting records, as described in the Colorado Breeding Bird Atlas (Kingery 1998), Colorado Birds (Andrews and Righter 1992), and Birds of Western Colorado Plateau and Mesa Country (Righter et al. 2004) in the vicinity of the project area, are summarized in Table 3. WestWater Engineering Page 6 of 15 July 2009 Table 3. BCC species that may be present in the project area Common Name Scientific Name Habitat & Breeding Records Pinyon Jay Gymn°rhinus cyanocephal us • Pifion-juniper woodlands. Brewer's Sparrow Spizella breweri • Sagebrush shrublands. Lewis's Woodpecker Melanerpes lewis • Pifion-juniper woodlands, riparian areas, open pine forests, and cottonwoods. Juniper Titmouse Baeolophus griseus • pinon juniper woodlands. No BCC were observed during the survey. Suitable habitats for the species listed in Table 3 were not observed in the project area. 4.4.3 Greater Sage -Grouse The Greater Sage -Grouse is recognized by the BLM and CDOW as a species of special concern. Greater Sage -Grouse occupy the sagebrush shrublands on the divide between the Parachute Creek and Roan Creek drainages. They require large, continuous areas of sagebrush habitat on flat gently rolling terrain with vegetation dominated by sagebrush (Artemesia tridentata var. vaseyana) and, generally, lacking an overstory of mountain shrub or woodland species. The project area is located more than 2 miles from the nearest CDOW-mapped historic Greater Sage -Grouse habitat. No sage -grouse sign was observed during the surveys. It is unlikely that sage -grouse will occur on the project site due to the limited amount of sagebrush and the existing disturbance. 4.5 Terrestrial Species 4.5.1 American Elk and Mule Deer Both well pads are situated within mule deer and American elk winter range and severe winter range, as well as mule deer critical winter range. Well pad F lies within a mule deer winter concentration area, as mapped by CDOW "NDIS" (Figure 2). During the survey, deer droppings and fresh tracks were observed throughout the project area. Elk and mule deer utilize the winter range extensively in the project area, following the snow line to higher elevations in the spring. Mule deer rely on the existing sagebrush and shrubs for their primary food source, while elk rely primarily on available grasses for food. Areas of pinon- juniper woodlands and scattered oakbrush and serviceberry copses provide necessary forage and production areas as well as escape, thermal, and loafing cover for deer and elk, particularly during the summer period. WestWater Engineering Page 7 of 15 July 2009 4.5.2 Black Bear and Mountain Lion CDOW "NDIS" mapping shows the project area to be within overall range for black bear and mountain lion. A black bear human conflict area also lies approximately 260 feet west of well pad D. Black bear are a common resident mammal throughout the area. Black bears are omnivorous and the diet depends largely on what kinds of food are seasonally available, although their mainstay is vegetation. In spring, emerging grasses and succulent forbs are favored. In summer and early fall, bears take advantage of a variety of berries and other fruits. In late fall, preferences are for berries and mast (acorns), where available. When the opportunity is present, black bears eat a diversity of insects, including beetle larvae and social insects (ants, wasps, bees, termites, etc.), and they kill a variety of mammals, including rodents, rabbits, and young or unwary ungulates. The area provides important habitat to black bear during the late spring, summer, and fall months with its abundance of berry and mast producing plants including. serviceberry, chokecherry, and Gambel oak. Black bear are in hibernation from mid-November through April to May. Mountain lion typically follow migrating deer herds in search of deer as the primary food source. Mountain lion have large territories and are highly mobile as they search for food or new territories. Mountain lion prefer to hunt in rocky terrain near woodland habitats. These habitat conditions occur near the project area. Mountain lion could travel through and hunt in the project area year-round. The project area is not mapped by CDOW as a potential mountain lion conflict area. 4.5.3 Small Mammals Common small mammal species (small game, furbearers, non -game) that may be present on the project site include coyote (Canis latrans), bobcat (Lynx rufus), golden -mantled ground squirrel (Spermophilus lateralis), northern pocket gopher (Thomomys talpoides), desert cottontail (Syvilagus audubonii), white-tailed jackrabbit (Lepus townsendii), and least chipmunk (Tarnias minimus). 4.5.4 Other Bird Species The project area does not lie within overall range for Wild Turkey (Merriam's - Meleagris gallopavo merriami), although it is possible that Wild Turkeys could occur in the area. The project area's shrublands, understory grasses, and nearby pinon-juniper stringers provide nesting and foraging habitats for various other migratory and non -migratory bird species, depending on the season of the year. Bird species that may occur on the project site include; Black -billed Magpie (Pica pica), Common Raven (Corvus corax), Mountain Bluebird (Sialia currucoides), Vesper Sparrow (Pooecetes gramineus), Tree Swallows (Tachycineta thalassina), and Turkey Vulture (Cathartes aura). WestWater Engineering Page 9 of 15 July 2009 4.5.5 Reptiles Plateau striped whiptail (Cnemidophorus velox), sagebrush lizard (Sceloporus graciousus), short - homed lizard (Phrynosora hernandesi), collared lizard (Crotaphytus collaris), Western terrestrial garter snake (Thamnophis elegans), Racer (Coluber constrictor), bull snake (Pituophis catenifer), and western rattlesnake (Crotalus viridis) are reptiles potentially occurring in the project area. 4.6 Aquatic Species 4.6.1 Amphibians Two BLM sensitive species, the northern leopard frog (Rana pipiens) and the Great Basin spadefoot (Spea intermontana), along with the tiger salamander (Ambystoma tigrinum) and chorus frog (Pseudacris triseriata), may occur near the project in any nearby suitable ponds or drainages. 4.7 Army Corp of Engineers (ACOE) WWE biologists also recorded any Army Corps of Engineers (ACOE) potential jurisdictional Waters of the United States (WOUS) encountered during the survey. Only one potential jurisdictional COE crossing was observed, and a culvert is already in place (Table 4, Figure 2). Table 4. Potential COE crossing observed within the Valley Farms Injection Wells D & F rolect area. Label UTM Zone Easting Northing Depth inches Width feet WOUS/Wetland COE Crossing 13 272026 4379044 1 1.5 Potential Jurisdictional WOUS 4.8 Cultural Resources At the request of Antero Resources, Grand River Institute (GRI) conducted a Class I cultural resource inventory for the proposed injection well locations, and is the subject of a separate document (GRI 2009). Findings show that no previously recorded sites are located within the project area, and that no further consideration of cultural resources is recommended for the proposed project. 5.0 AFFECTS TO WILDLIFE 5.1 Wildlife Impact Assessment The Valley Farms Injection Wells D & F will affect site-specific native vegetation and wildlife habitat adjacent to the project site. Because the area has already been disturbed, and the existing wells will be converted into injection wells, the project will minimally affect wildlife. The project will contribute to the overall cumulative impacts to the wildlife populations in the area that are experiencing gradual habitat loss, fragmentation, alteration, and displacement through increased development. WestWater Engineering Page 10 of 15 July 2009 5.1.1 Terrestrial Species 5.1.1.1 Elk and Mule Deer Potential affects include the temporary loss of a small amount of elk and mule deer winter ranges. Human presence and activities during the project may create a direct disturbance for elk and deer populations within and immediately adjacent to the project area. 5.1.1.2 Birds Greater Sage -Grouse: Greater Sage -Grouse are highly dependent on sagebrush dominated habitats in western Colorado. The quality and quantity of this habitat type dictates its suitability for sage -grouse. Disturbance to sagebrush shrublands that reduces the availability and suitability of presently occupied habitat would affect this species. However, no suitable Greater Sage - Grouse habitat is located within or near the proposed project. Passerine Species: The affects to foraging and nesting habitat to a small number of bird species is expected to be minimal. If the project should require any clearing of vegetation beyond the boundaries of the existing pad, affects to local bird species would be more significant should vegetation clearing occur during the breeding/nesting season. Raptors: No raptor nests were observed within 0.25 miles of the well pads. Raptors may be indirectly affected by disturbance associated with the proposed project, including equipment and human presence. 5.1.1.3 Black Bear and Mountain Lion Due to the large home range of both black bear and mountain lions, and because of the extensive amount of available habitat for these species, no significant affects from this project for these species are expected. 5.1.1.4 Small Mammals The amount of available habitat for small mammals, including bats, should not be affected significantly by the proposed injection wells. 5.1.1.5 Reptiles The amount of available habitat for reptiles should not be impacted significantly by the proposed injection wells. Disturbance will occur primarily within an existing disturbed site, which is not expected to affect reptile populations. 5.1.2 Aquatic Species 5.1.2.1 Amphibians Downstream individuals would be most susceptible in the event contaminants were introduced to surface water during construction or operational activities. The amount of available habitat for amphibians should not be affected significantly by the proposed injection wells. Disturbance will occur primarily within an existing disturbed site, which is not expected to affect amphibian populations. WestWatcr Engineering Page 11 of 15 July 2009 5.1.2.2 Endangered Fish The Colorado pikeminnow and the razorback sucker are both federally -listed fish species that occur in the Colorado River. Potential impacts from the proposed injection wells include: water use, sedimentation of tributaries to the Colorado River, and spills of chemicals and fuels from equipment. It is not likely that endangered fish will be affected by this project, due to both the project size and its location on existing pads. Appropriate application of stormwater Best Management Practices (BMPs) and Spill Prevention Counter Control (SPCC) measures will also help reduce any potential impacts to aquatic species. 6.0 AFFECTS TO TESS PLANT SPECIES No TESS plants or their habitats were found during surveys, and therefore no affects on TESS plants are expected. 7.0 MITIGATION RECOMMENDATIONS The following recommendations for mitigation are presented for maintenance and improvement of wildlife habitat, quality, and prevention of human -caused impacts to resources. 7.1 Maintenance and Restoration of Habitat Sagebrush communities in the project area have declined over the years and continue to do so as a result of development and loss of habitat. Noxious weeds and invasive plant species have now invaded many habitats due to construction and ground clearing of native vegetation. Woodlands, sagebrush, and native grasses are key food sources for elk and mule deer, and provide nesting and foraging habitat for a variety of migratory birds and small mammals. Reclamation plans should include efforts to restore these vegetation communities, particularly the sagebrush community for sage -obligate species. Reclamation recommendations include the following: 1. Seeding of native Wyoming and big basin sagebrush should be added to the re -vegetation plan. Local, ecologically adapted sagebrush seed from the existing sagebrush vegetation near the project area should be used in reclamation. 2. Ongoing control of noxious and invasive weeds is recommended as an additional method to maintain native vegetation communities and favorable wildlife habitats. An "Integrated Vegetation and Noxious Weed Management Plan" is provided for this project in a separate report. 7.2 Planning for Sensitive Time Periods and Areas 7.2.1 Mule Deer and Elk Disturbance associated with construction equipment and personnel may cause elk and mule deer to select habitats in more secluded areas away from the proposed injection wells. Any construction and/or operational activities during the winter months will impact deer and elk WestWater Engineering Page 12 of 15 July 2009 winter range as mapped by the CDOW "NDIS". According to the Colorado Oil and Gas Conservation Commission's amended rules, effective April 1, 2009, elk winter range is excluded from the rules as sensitive wildlife habitat. Deer critical winter range and deer severe winter range are included in the new 2009 rules, both of which are located within the project area (COGCC 2009). No development activity should take place between January 1 and March 31 to meet the CDOW and COGCC standards for the protection of mule deer critical winter range in the project area. 7.2.2 Migratory Birds In order to comply with the Migratory Bird Treaty Act by showing a good faith effort to reduce potential impacts on nesting birds, if any brushltree clearing is necessary, it should take place outside of the nesting seasons. Nesting season is generally considered between May 15 and July 31 in this area for most species. June 1 to July 15 is the peak period when most incubation and brood rearing takes place. If brushltree clearing can occur prior to May 1, most affected birds will relocate to alternate nesting sites. After mid-to-late July, most fledging has occurred and brushltree clearing impacts would be minimized. Pinyon Jays are an exception to typical nesting periods in this area and are known as an early nester. Records show nests with eggs as early as March 23. Often, young birds have fledged by May 15. Because suitable Pinyon Jay habitat is not present at the project site, the pre -May 1 vegetation clearing recommendation is acceptable and adequate to avoid destruction of any potentially active migratory bird nests. 7.2.3 Greater Sage -Grouse No affects to Greater Sage -Grouse are expected to occur as a result of the proposed project. No specific planning is recommended in regards for Greater Sage -Grouse. 7.2.4 Raptors Activities associated with the proposed injection wells are not likely to impact raptor populations, and therefore, no mitigation measures are necessary. 7.3 Other Mitigation Practices 7.3.1 Erosion Efforts to control soil erosion within the project area should be implemented. Disturbed soils within the project area are susceptible to erosion and downstream water quality could be negatively affected by increased soil erosion. In addition to stormwater management around the project site, other current factors (noxious weeds, livestock grazing, other natural gas development) affecting soil erosion should be managed and remedial measures implemented. Prior to any construction which involves potential stream crossings, appropriate consultation with the U.S. Army Corps of Engineers (ACOE) is recommended. 7.3.2 Black Bears Black bears will likely move through the general project area and could be attracted to human - related food sources (garbage, pet foods, and barbeque grills). In order to prevent human injury and/or the tin -wanted removal, injury, or destruction of bears, it is recommended that food and WestWater Engineering Page 13 of 15 July 2009 garbage storage and removal be done in a timely and secure manner so as to not habituate bears to the human activities of the project. 8.0 REFERENCES Andrews, R., and R.

Box 3543 Grand Junction, Colorado 81502 BLM Antiquities Permit No. C-52775 State of Colorado Archaeological Permit No. 2009-82 Submitted to Board of County Commissioners Garfield County, Colorado Abstract At the request of Antero Resources, Grand River Institute (GRI) conducted a Class I cultural resource inventory for the proposed Valley Farms Pad D and Pad F well locations. The project area will affect less than 15 acres that are located on private land in Garfield County, Colorado. This work was performed under State of Colorado Archaeological Permit No. 2009-82 and BLM Antiquities Permit No. C-52775. The Class I files search and report preparation were performed on the 6'b of July 2009. The Class I inventory was undertaken to ensure the project's compliance with state and federal legislation governing the identification and protection of cultural resources on federal lands that will be affected by a government action. The purpose of the cultural resources investigation was to identify previously recorded resources within or near the proposed facility that may be adversely affected by the proposed action and to evaluate the potential of additional such resources in the project areas. As a result of the files search, no sites have been previously recorded within the proposed project areas. Three historic ditch segments have been recorded along Dry Hollow Creek within the SW 1/4 of Section 15, but all are located well outside of the proposed area of disturbance. Two other ditches appear on the U.S.G.S. quadrangle map that have not been recorded, but again occur outside the area of disturbance. Accordingly, no further consideration of cultural resources is recommended for the proposed project. ii TABLE OF CONTENTS Introduction 1 Location of the Project Area 1 Environment 1 Paleoclimate 3 Files Search Results 3 Discussion/Archaeological Assessment of Cultural Resources 5 Summary and Recommendations 5 References 6 LIST OF FIGURES AND TABLES Figure 1.

The project area will affect less than 15 acres that arc located on private land in Garfield County, Colorado. This work was performed under State of Colorado Archaeological Permit No. 2009-82 and BLM Antiquities Permit No. C-52775. The Class I files search and report preparation were performed on the 6'h of July 2009 by Carl E. Conner, Principal Investigator and Barbara Davenport. The Class I inventory was undertaken to ensure the project's compliance with state and federal legislation governing the identification and protection of cultural resources on privately owned lands that will be affected by a government action. It was done to meet requirements of the National Historic Preservation Act (as amended in 1992), the National Environmental Policy Act of 1969 (42 U.S.C. 4321), the Federal Land Policy and Management Act of 1976 (43 U.S.C. 1701), and the Archaeological Resources Protection Act of 1979 (16 U.S.C. 470aa et seq., as amended), and Article 80.1, Colorado Revised Statutes. These laws are concerned with the identification, evaluation, and protection of fragile, non-renewable evidence of human activity, occupation, and endeavor reflected in districts, sites, structures, artifacts, objects, ruins, works of art, architecture, and natural features that were of importance in human events. Such resources tend to be localized and highly sensitive to disturbance. All work was performed according to guidelines set forth by the Office of Archaeology and Historic Preservation (OAHP) of the Colorado Historical Society. Location of the Project Area The study area is located about 1.0 mile south of the town of Silt in Garfield County, CO. The pads will be constructed in T. 6 S., R. 92 W., Sections 14 and 15; 6th P.M. (Figure 1). Environment The proposed project is within the Piceance Creek Basin, one of the major geologic subdivisions of Colorado. The Piceance Creek Basin is an elongate structural downwarp of the Colorado Plateau province that apparently began its subsidence approximately 70 million years ago during the Laramide Orogeny. Sediments from surrounding highlands were deposited in the basin, accumulating to a thickness of as much as 9000 feet by the lower Eocene epoch, when subsidence ceased. Regional uplift occurred in the Late Tertiary, and erosion of the area has continued since (Young and Young 1977:43-46). The project area lies south of the Colorado River on a terrace west of Dry Hollow. 1 .�lRai# ,v1 .

The project area is indicated. [GRI #2967, 7/6/09] 2 The region has a cool desert climate. Precipitation ranges between 10 and 14 inches, although the surrounding mountain areas may receive up to 20 inches. Temperatures range from about 95 degrees F in the summer to -5 degrees F during January. A frost -free period of about 150 days is the maximum (USDA SCS 1978b:403). Paleo-environmental data for the area are scant, but it is agreed that gross climatic conditions have remained fairly constant over the last 12,000 years. Still, changes in effective moisture and cooling/ warming trends probably affected the prehistoric occupation of the area. Elevations of the project areas range from 5520 to 5640 feet, which fall within the Upper Sonoran zone. Natural vegetation within and surrounding the pad locations consists primarily of open sage/greasewood flats, and cheatgrass, agricultural lands and on the nearby ridges pinyon/juniper forest. Ground visibility in the project area averages 30%. Present land uses in the vicinity are open range, agricultural fields and energy development. Wildlife inhabitants including mule deer, elk, coyote, and black bear are common in the surrounding area, as are cottontail rabbits and various rodents. Mountain lion, bobcat, fox, skunk, badger, and weasel are also likely inhabitants. Bird species observed in the area include the jay, raven, red -shafted flicker, long-eared owl, golden and bald eagles and various other raptors. Paleoclixrate Relatively small changes in past climatic conditions altered the exploitative potential of an area and put stress upon aboriginal cultures by requiring adjustments in their subsistence patterns. Therefore, reconstruction of paleoenvironmental conditions is essential to the understanding of population movement and cultural change in prehistoric times (Euler et al. 1979). To interpret whatever changes are seen in the archaeological record, an account of fluctuations in past climatic conditions must be available or inferences must be made from studies done in surrounding area. Generally, only gross climatic trends have been established for western North America prior to 2000 BP (Antevs 1955; Berry and Berry 1986; Madsen 1982; Mehringer 1967; Peterson 1981; Wendlund and Bryson 1974). Scientific data derived from investigations of prehistoric cultures and geoclimatic and bioclimatic conditions on the southern Colorado Plateau over the past two millennia have achieved a much greater degree of resolution (Dean et al. 1985). Files Search Results Cultural resource investigations in the region have yielded surface diagnostic artifacts and excavated cultural materials consistent with the regional cultural history. Evidence provided by chronometric diagnostic artifacts and radiocarbon analyses indicate regional occupation during the Paleoindian Era, Archaic Era, Formative Era, and 3 Protohistoric Era. Historic records indicate occupation or use of the region by EuroAmerican trappers, settlers, miners, and ranchers as well. Overviews of the prehistory and history of the region are provided in the Colorado Council of Professional Archaeologists' publications entitled "Colorado Prehistory: A Context for the Northern Colorado River Basin" (Reed and Metcalf 1999), and "Colorado History: A Context for Historical Archaeology" (Church et al. 2007). Files searches for known cultural resources within the project area were made through the Colorado Historical Society's Office of Archaeology and Historic Preservation. This review identified three previously recorded cultural resources (Table 1) near the project area. Additionally, three cultural resource projects have been conducted in the general vicinity (Table 2). Table 1. List of previously recorded resources near the proposed project areas.

Project # Title/Author/Date/Contractor GF.LM.R376 Title: ANTERO DIXON B WELL FAD, ACCESS ROAD AND PIPELINE: A CLASS III CULTURAL RESOURCE INVENTORY, GARFIELD COUNTY, COLORADO (BLM GSFO# 5407-12 NEPA C0140-2007-102EA) Author: MCDONALD, KAE Date: 03/01/2007 Contractor: METCALF ARCHAEOLOGICAL CONSULTANTS FOR THE BLM, GLENWOOD SPRINGS FIELD OFFICE 4 Project it Title/Author/Date/Contractor MC.PA.R66 TITLE: ARCHAEOLOGICAL RECONNAISSANCE OF THE CRAIG -RIFLE 345 KV ELECTRICAL TRANSMISSION LINE, MOFFAT COUNTY, COLORADO AUTHOR: JENNINGS, CALVIN H. AND KATHLEEN SULLIVAN DATE: 02/01/1977 CONTRACTOR: LABORATORY OF PUBLIC ARCHEOLOGY, COLORADO STATE UNIVERSITY MF.PA.CR TITLE: CIG RIFLE 345 KV ELECTRICAL TRNS LINE AUTHOR: JENNINGS CALVIN H; SULLIVAN KATHLEEN DATE: 02/01/1977 CONTRACTOR: LABORATORY OF PUBLIC ARCHEOLOGY Discussion/Archaeological Assessment of Cultural Resources The data derived from this inventory supports conclusions reached by a predictive model study conducted for the BLM's Grand Junction Resource Area. In that study, eight variables were found to be the most useful in the prediction of open air sites. These include site slope, aspect, horizontal distance to water (permanent and nearest), vertical distance to water (permanent and nearest), view angle (horizontal), distance to vantage overlook, nearby relief (100 m. and 150 m. radius), and shelter from wind (O'Neil 1993:207-208). There is a concentration of sites generally within about 0.25 mile of the main drainages in the area to the south of the proposed well pads and most occur within the present day pinyon juniper, big sagebrush, desert shrub or saltbush communities. However, the key factor appears to be proximity to the water source. Most likely prehistoric sites in the general vicinity were utilized during periods of migration between the mountainous regions of the Grand and Battlement Mesas and the White River Plateau, or in the lower elevations along the Colorado River during the winter months. EuroAmerican historic and modem irrigated fields occur in the lowlands north of the project area. Summary and Recommendations As a result of the files search, no sites have been previously recorded within the proposed project areas. Three historic ditch segments have been recorded along Dry Hollow Creek within the SW 114 of Section 15, but all are located well outside of the proposed area of disturbance. Two other ditches appear on the U.S.G.S. quadrangle map that have not been recorded, but again occur outside the area of disturbance. Accordingly, no further consideration of cultural resources is recommended for the proposed project. 5 References Antevs, E. 1955 Geologic -climate dating in the west. American Antiquity 20:317-355.
