Regulatory & Land Advisor —Midstream Services Encana Oil & Gas (USA), Inc. 370 17th Street, Ste 1700 Denver, CO 80202 RE: Encana's Hunter Mesa Water Storage Facility Dear Brenda, This office is in receipt ofadditional information you submitted in your letter dated January 28, 2009 which was received in this office on January 29, 2009. Based on further review, it appears virtually all of the conditions have been met with the exception of condition 9(b) which requires the following: The Applicant shall install a waterfowl deterrence system that consists of the placement of high -tensile wire at regular intervals across the pond. These wires act as a visual deterrent to birds attempting to land on the water, and as a noise deterrent, as the stretched wirecreatesan ultrasonic (inaudible to humans) sound. Staff cannot forward a permit to the Board of County .Commissioners for signature until Encana has constructed the high -tensile wire. As you are aware, this was a specific requirement by the BOCC in a public hearing. Once you receive this letter, give me a call to discuss what options there may be available to Encana. Do not hesitate to contact this office should you have any questions. Very truly yours, Fre A.

(EnCana) Hunter Mesa Water Storage Facility Dear Mr. Jarman: On January 20, 2003 the Garfield County Board of County Commissioners (BOCC) approved the EnCana Hunter Mesa Water Storage Facility Special Use Permit Application (Resolution 2003-02) subject to compliance with certain conditions. The purpose of this letter is to confirm compliance with, and agreement to, the county's conditions so that the Special Use Permit for the facility may be issued to EnCana. For your reference, the BOCC conditions appear in italicized type and the EnCana response appears in normal font. 1. All representations of the Applicant, either within the application or stated at the meeting before the Board, shall be considered conditions of approval, unless specifically altered by the Board. EnCana agrees to this condition. 2. The Applicant shall comply with all applicable requirements of the Garfield County Zoning Resolution of 1978, as amended. EnCana agrees to this condition. 3. The Applicant shall comply with all State and Federal regulations and standards, such as Water and Air Quality. EnCana agrees to this condition. 4. The Applicant shall comply with the following recommendations from the Garfield County Road and Bridge Department: a) The Applicant shall continue to provide support for the continued maintenance of County Road 319 as necessary. EnCana agrees to this condition, as necessary and in accordance with its use. b) The truck drivers shall abide by the posted speed limit of 35 M.P.H. on County Road 319. EnCana supports the adherence to posted speed limits for all its employees and contractors, including truck drivers. 5. The Applicant shall comply with the following recommendations from the Colorado Division of Wildlife: a) In addition to the 8 -foot high perimeter fence, a 2 to 3 foot high mesh small game fence, immediately surrounding the pits and buried 6 to 8 inches in the ground, shall be installed. EnCana agrees to this condition. Pictures are provided in Attachment 1. b) Escape ramps shall be installed in the pits to allow wildlife species that manage to reach the water to escape the pits. EnCana agrees to this condition. Pictures are provided in Attachment 1. c) Pond netting over all the pits, or another method of mitigation acceptable to the Colorado Division of Wildlife, shall be installed to help prevent migratory birds from resting and/or foraging on the ponds, particularly during winter months. EnCana has experimented with methods for its various ponds to mitigate the potential for migratory birds to contact the ponds and continues to work closely with the Division of Wildlife in this regard. The Division of Wildlife (DOW) has expressed to EnCana its appreciation for EnCana's efforts to work to alleviate potential loss and impacts to wildlife. However, the DOW has also expressed concern to EnCana regarding the DOW'S ability to provide written acceptance for any method that mitigates migratory bird contact with ponds because they want to ensure that they do not relieve EnCana (or any operator) from the responsibility of not harming wildlife. At the county's request, EnCana can establish and facilitate a meeting between Garfield County and the DOW to discuss this issue further. d) Death of any migratory birds caused by the proposed facility shall be immediately reported to the Colorado Division of Wildlife and the US Fish and Wildlife Services. To date, there have been no known deaths of migratory birds associated with this facility; however, EnCana agrees to this condition. e) Pits shall be monitored for oil. Shall any oil reach the pits, measures shall be taken to immediately remove the oil. EnCana monitors the pits for oil on a daily basis. In the case that oil is found in the pits, it has and will continue to be removed by skimming the oil from the top of the water. f) Steps should be taken to ensure any run-off of by-products from the facility be contained on site. This facility was built consistent with EnCana's Stormwater Management Plan. A copy of this plan (sans appendices) is included in Attachment 2. 6. Vibration, emission of smoke and particulate matter, and the emission of heat or radiation shall comply with applicable Federal, State, and County laws, regulations and standards. EnCana agrees to this condition. 7. The Applicant shall comply with all Local, State and Federal Fire Codes that pertain to the operation of this type of facility. An Emergency Plan shall be filed with the County and the appropriate Fire District. EnCana agrees to this condition. EnCana's Emergency Plan entitled, "Emergency Response Plan, November 2007, North and South Piceance: Exploration & Production" has been delivered to the Garfield County Emergency Manager (Deputy Chris Bornholdt) and the Rifle Fire Protection District (Mr. Mike Morgan). 8. The Applicant shall comply with the appropriate noise regulations as per Colorado State Statute 25-12-130. EnCana agrees to this condition. 9. The following commitments shall be adhere to: a) The exterior of the holding tanks shall be painted in a beige color to match the surrounding terrain. EnCana agrees to this condition. Pictures are included in Attachment 1. b) Signage shall be visible and shall include the company name, address and 24-hour toll-free emergency phone number. Signage shall comply with the County's sign regulations. EnCana has posted signage around the facility indicating the company name and the 24-hour emergency phone number. Pictures are included in Attachment 1. c) Groundwater resources shall be protected at all times. The pits shall be lined with impermeable HDPE (High Density Polyethylene). If groundwater is encountered during construction, monitoring wells shall be installed and sampled regularly. In the event of any violation with respect to water pollution, the Applicant shall provide proof of compliance with applicable Federal, State, and County laws, regulations and standards. The pits at Hunter Mesa are lined with impermeable high-density polyethylene (HDPE). Groundwater was not encountered during construction of the facility. In the event of a potential violation with respect to water pollution, EnCana will provide documentation of compliance with applicable Federal, State, and County laws, regulations and standards at the county's request. Water samples for the Hunter Mesa Water Treatment Facility were submitted to Garfield County's Building and Planning Department in 2004, 2005, 2007 and 2008 and copies are included in Attachment 3. d) Driftage shall be contained on-site. A berm, approximately 20 feet tall and 60 feet wide, at its base, shall be installed downwind (south and east) of the pits. EnCana agrees to this condition. e) Extra measures shall be taken if noise or odors are emanated beyond the site boundary. EnCana agrees to this condition. To date, EnCana has not reported or had any complaints of noise or odors emanating beyond the site boundary. 0 Fire Control Measures provided by the Applicant in the application shall be adhered to. EnCana agrees to this condition. g) Four (4) 175 watt mercury vapor lights will be installed. These lights will be set to turn on automatically at dusk and turn off at sunrise. Two (2) lamps will be mounted on the east side of the tanks. Two (2) lights will be mounted on the west boundary to light the ponds for safety purposes. EnCana agrees to this condition. h) Landscaping shall be directed towards erosion control. Any areas disturbed by construction and not covered by liner or equipment shall be resurfaced with sand and gravel. EnCana agrees to this condition. Any areas disturbed by construction and not covered by a liner or equipment have been resurfaced with sand and gravel. 10. Prior to the issuance of the Special Use Permit, the Applicant shall submit a copy of the Reclamation Bond. The Applicant shall comply with State and Local Noxious Weed regulations. EnCana agrees to this condition. EnCana has submitted a Reclamation Bond for this facility, effective as of December 16, 2008, and a copy of the bond is provided in Attachment 4. 11. The operation of the Facility shall be done in accordance with any Federal, State or Local regulations governing this operation of this type of Facility. EnCana agrees to this condition. 12. The operation of this Facility shall be in accordance with the provisions allowed within the Surface Lease Agreement signed by the Applicant (Lessee) and the land owner (Lessor). EnCana agrees to this condition. 13. The construction of the Facility shall be done in a manner to mitigate any problems which may occur due to the possible shrinking or swelling of the soils on-site. The water storage facility was constructed in 2003-2004. No tears in the HDPE liner material, which may indicate shrinking or swelling of soils, have occurred to date. 14. The issuance of this Special Use Permit is subject to an annual review of the water chemistry of the water contained within the evaporation pits, at such time when freestanding water is within the pit. This analysis will be presented to the Planning Department on the 1st day of July for the duration of the Facility. The analysis of this water will be at the sole cost of the Applicant/Owner. If this water is determined, through this analysis, to be hazardous or toxic, based on applicable standards, then the Applicant/Operator is required to submit an additional Special Use Permit application, with appropriate fees, to address and mitigate the potential hazard(s). EnCana agrees to this condition. Copies of reports submitted to the Garfield County Building and Planning Department in 2004, 2005, 2007 and 2008 are provided in Attachment 3. 15. The County reserves the right to retain outside expertise, at the expense of the Applicant/Operator of the Facility, in an effort to conduct tests or analyses of the physical nature, water chemistry or groundwater properties on and away from the site. EnCana recognizes that the County reserves this right. However, in an effort to eliminate miscommunication, EnCana requests that it be notified by the county prior to the county retaining the outside expertise and be given an opportunity to correct the situation. 16. The Facility is for the sole use of the Applicant. If any other entities are to be added as users, than these entities would be subject to an additional Special Use Permit review. EnCana agrees to this condition. 17. The Applicant/Operator shall consult with appropriate authorities as to the planting and care of suitable landscaping plants. EnCana has covered all disturbed land with sand and gravel. 18. The proposed lease parcel is subdivided from the parent parcel either by the appropriate action of the Board of County Commissioners or the recording of a deed of at least 35 acres of land surround the leased area, in the name of the Applicant. EnCana believes that this condition of approval was added inadvertently. EnCana is not aware of any requirement or arrangement to subdivide the proposed lease parcel. I observed that the issue following EnCana's request to receive approval for this SUP during the January 6, 2003, Public Hearing was a request for approval of an exemption from the definition of subdivision request for Richard and Karen Rhodes (see Proceedings of the Board of County Commissioner, Garfield County, Colorado, Meeting Minutes of January 6, 2003) and assume that this condition was inadvertently added to EnCana's conditions of approval instead of the conditions of approval for the issue that followed EnCana's during the January 6, 2003 public hearing. To this extent, the parcel where this facility is located has not been subdivided per this condition. 19. Licensing of all out-of-state vehicles and equipment to be used on this project within the County of Garfield, State of Colorado. EnCana agrees to this condition. I trust that these responses provide sufficient information regarding the BOCC conditions of approval such that a Special Use Permit for this facility can be issued. If you have any questions or need additional information, ple-se don't hesitate to contact me at (720) 876-3989. cerely, r`enda R. Linster egulatory & Lan.

EnCana Oil & Gas (USA) Inc. (EnCana) has submitted a General Permit Application to WQCD, a copy of which is provided as Appendix A. This Master SWMP has been prepared in compliance with CDPHE WQCD, the Federal Clean Water Act (CWA), and the National Pollutant Discharge Elimination Permit (NPDES) regulations found in 40 CFR, Part 122.26 for stormwater discharges. The objectives of this Master SWMP are to: 1. Identify all potential sources of pollution which may reasonably be expected to affect the quality of stormwater discharges associated with construction activity within this Master SWMP permit area at each project site; 2. Describe the practices to be used to reduce the pollutants in stormwater discharges associated with construction activity within this Master SWMP permit area at each project site (also known as Best Management Practices (BMPs)); and ensure the practices are selected and described in accordance with good engineering practices, including the installation, implementation and maintenance requirements; 3. Be properly prepared and updated to ensure compliance with the terms and conditions of the Stormwater Construction Permit; 4. Work hand in hand with the Site Specific Records, as described in the following section; and 5. Serve as an education tool and comprehensive reference/guide to stormwater management for inspectors, surveyors, engineers, and EnCana employees and contractors. EnCana construction activities fall under one of two types. Exploration and Production (E&P) sites involve the construction of well pads, roads, and other facilities. Midstream Services (also referred to as Gas Gathering) sites involve the construction of pipelines and compressor, treatment, and other facilities. This Master SWMP is intended to address stormwater management for any and all of these sites within this Master SWMP's Permit Coverage Area. 1.1 Site Specific Records While Volume 1 of the Master SWMP contains all of the general permit area information, Volume 2 of the Master SWMP contains all of the Site Specific Records including all Individual Stormwater Site Plans (Site Plans), as discussed in Section 2.8, and all Inspection and Maintenance Reports (discussed in Section 5.4). These Site Specific Records contain information specific to each site (each well pad, compressor station, section of road/pipeline, etc.), including information on areas of disturbance, ecosystems and vegetation, soil types, percent pre -disturbance vegetation, etc. Any changes to the design of individual sites or the BMPs used at those sites will be noted on the Site Plans as those changes occur, and kept with the Site Specific Records. The Site Specific Records (Volume 2 of the Master SWMP) are bound separately from the body of this Master SWMP; however, both are readily available during any inspection. Both the body of this SWMP (Volume 1) and the Site Specific Records (Volume 2) comprise the entire SWMP, and go hand in hand in keeping EnCana in compliance with stormwater regulations. The Site Specific Records will be kept at the EnCana field office in Parachute during active construction and site inspections to ensure accurate implementation, inspections, and maintenance of BMPs, as well as timely revisions to the Site Specific Records.

Activities at the Permit Coverage Area will likely involve the construction of: • Well pads • Access roads • Pipelines • Compressor stations The above construction activities are only typical and may vary once construction begins. Up-to-date information on the construction of well pads, roads, pipelines, etc. will be kept with the Site Specific Records (Volume 2 of the Master SWMP). 2.1 Sequence of Major Activities Site specific, scheduling, surface use agreements, and/or other constraints can and/or may dictate changes in construction sequences. Significant sequence changes are addressed in the Site Specific Records (Volume 2 of the Master SWMP). Specific details on the construction and maintenance of BMPs mentioned below are provided in the Stormwater Manual of Best Management Practices (BMP Manual) as discussed in Section 3.3. 2.1.1 Well Pads and Roads Construction activities for well pads and roads are generally completed in the following sequence: Preconstruction: 1. Surveys. Topographic, vegetation, wildlife and archeology, as dictated. 2. Temporary BMP's. Where physical access is available, installation of terminal perimeter and temporary sediment controls, such as wattles, silt fence and/or other as necessary. Actual BMPs used for each site are shown on the Site Plans (discussed in Section 2.8) and kept with the Site Specific Records (Volume 2 of the Master SWMP). Construction: 3. Vegetation Clearing. Vegetation will be cleared/grubbed and placed along the perimeter at the terminal discharge edges/points in a windrow and/or dam beyond the edge of excavation and at any run -on -protection discharge points, and/or chipped or other depending on landowner requirements. St\South Rockies\Operations - North Piceance \0 County and Local Permits\COA Letters\Hunter Mesa Water Storage Facflitv\Attachment 2\0rchard Unit SWMP 100% 2-1 January 2008 4. Diversions and Retention Reservoirs. After vegetation clearing and prior to topsoil stockpiling, diversions are to be placed for run -on -protection (ROP) to prevent the greater landscape from discharging onto the planned disturbance. Temporary sediment control BMPs shall be placed at the discharge points of the ROP until permanent erosion controls can be installed along the entire length of the ROP. Diversions are to be installed along the terminal discharge edge inside of the vegetation windrows to convey site water/sediment to terminal discharge points where rough retention reservoirs are to be installed. The retention reservoir outlets are to receive temporary sediment control BMPs until permanent retention reservoirs and erosion, drainage, and sediment BMPs can be installed. 5. Topsoil Stripping/Conservation. All ACCESSIBLE TOPSOIL is to be removed from areas that are to be excavated, covered in subsoils, or turned into stabilized unpaved surfaces. If initial topsoil stockpile areas are insufficient to accommodate the quantities of topsoil being generated, the excess is to be placed at either end of the subsoil stockpile and segregated as much as possible. After major earthwork, grading, and erosion/drainage/sediment controls are complete, any areas that can be identified for immediate interim reclamation shall receive topsoil. 6. General Rough Grading. The site location will be graded to provide suitable surfaces for vehicle traffic and/or building sites, and may be graded to establish surface drainage patterns, such as berms or roadside ditches as necessary. 7. Facility Specific Grading. Individual facilities may require additional excavation to allow for construction of foundations. Excess soil will typically be used in general site grading. 8. Foundation Construction. To support facilities (such as tanks, processing equipment, etc), foundations will be constructed. Foundations may consist of select backfill, concrete spread footings, or piles. Finished support elevations are to be installed twelve to eighteen inches (12-18") above finished grade or the lowest point of the facility. 9. Facility Construction. Tanks, processing equipment, etc. will be constructed. Interim Reclamation: 10. Gravel Surfacing. Areas used for access, parking, or materials staging will typically be gravel surfaced. 11. Reclamation of Unused Areas. Areas not needed for facilities, roads, parking, or materials staging will generally be reclaimed. Salvaged topsoil will be spread and the vegetative seed mix will be applied. 12. Application of Erosion Stabilization. Depending on terrain (e.g. steep slopes and drainage crossings) additional measures may be applied to increase stability of the reclaimed area. Final Reclamation: 13. Reclamation of Post -Operation Areas. When operation of well pad or road is no longer necessary, the area will be decommissioned and all newly disturbed areas will be reclaimed. Any remaining topsoil will be spread and the vegetative seed mix will be applied. This may occur after termination of this permit and under the coverage of a new construction permit. 2.1.2 Pipelines Construction activities for pipelines are generally completed in the following sequence: Preconstruction: 1. Surveys. Topographic, vegetation, wildlife and archeology, as dictated. 2. Mark Right -Of -Way. The construction right-of-way (ROW) will be marked prior to construction with laths and/or flagging. Laths/flagging will be maintained throughout construction and will not be removed until after reclamation activities have been completed. S:South Rockies\Operations - North Piceancel0_ County and Local Permits\COA Letters\Hunter Mesa Water Storage Facility Attachment 2\Orchard Unit SWMP 100% 2-2 January 2008 3. Temporary BMPs. EnCana's stormwater inspectors will determine locations to install preconstruction temporary erosion control devices, per site specific BMP installation plans and as necessary. EnCana's contractor will maintain the erosion control structures as directed by the stormwater inspectors throughout all phases of construction, or until permanent erosion control measures are installed. Actual BMPs used for each site are shown on the Site Plans, which are kept with the Site Specific Records (Volume 2 of the Master SWMP). Construction: 4. Vegetation Clearing. If necessary, vegetation will be cleared and placed in a windrow at the edge of the work area to be used later in reclamation activities, removed from the construction site, or burned/chipped depending on landowner requirements. Details for windrows are provided within the Stockpiling BMP of the BMP Manual (discussed in Section 3.3). 5. Topsoil Stripping. All ACCESSIBLE TOPSOIL (from the entire width of the right-of-way) will be removed and temporarily stockpiled along the up -hill side of the right-of-way (if terrain grades will allow) for later use in reclamation activities. 6. General Grading. For pipeline segments that occur in relatively rough terrain, general grading will be conducted to create a safe and workable ground surface. This is generally done to form a relatively level work surface on steep cross slopes and to reduce slopes in undulating terrain (arroyo and wash crossings). The site location will be graded to provide suitable surfaces for vehicle traffic and/or building sites, and may be graded to establish surface drainage patterns, such as berms or roadside ditches as necessary. 7. Trench Excavation. The trench needed for pipeline installation is almost always off -set in the ROW. The surveyors may indicate the location of the trench on their pipeline lateral. Generally, the trench will be located in the first third of the ROW. The remaining two thirds of the ROW will be used for working space. The trench depth and width will vary with the number of pipes to be installed and the pipe diameter. Generally, a 4 -foot deep trench will be excavated by track -mounted excavators. The ditch will be excavated and sloped in accordance with OSHA specifications. The cover from top of pipe to ground level will be a minimum of 36 inches. Where rock is encountered, tractor -mounted mechanical rippers or rock trenching equipment may be used to facilitate excavation. The trench will be excavated and subsoil material stockpiled within the confines of the approved right-of-way limits. Trench spoil will be stored in a separate location from the previously segregated topsoil. 8. Pipe Installation. Pipe installation will include stringing, bending for horizontal or vertical angles in the alignment, welding the pipe segments together, coating the joint areas to prevent corrosion, and then lowering -in and padding. 9. Stringing. Pipe will be hauled by truck to the pipeline ROW. Each joint of pipe will be unloaded and placed parallel to the ditch. 10. Bending. After the joints of pipe are strung along the ditch, individual joints of pipe may need to be bent to accommodate horizontal and vertical changes in direction. Field bends will be made utilizing a hydraulically operated bending machine. Where the deflection of a bend exceeds the allowable limits for a field -bent pipe, factory (induction) bends will be installed. 11. Welding. After the pipe joints are bent, the pipe is lined up end-to-end and clamped into position. The pipe is then welded in conformance with 49 CFR Part 192, Subpart E. "Welding of Steel Pipelines" and API 1104, "Standard for Welding Pipelines and Related Facilities". 12. Welding Inspection. Welds will be visually inspected by a qualified inspector. Any defects will be repaired or cut out as required under the specified regulations and standards. 13. Coating. To prevent corrosion, the pipe will be externally coated with fusion bonded epoxy coating prior to delivery. After welding, field joints will be coated with fusion bond epoxy coating, tape and primer, or shrink sleeves. Before the pipe is lowered into the ditch, the pipeline coating will be visually inspected and tested with an electronic detector, and any faults or scratches will be repaired. 14. Lowering -In and Padding. Once the pipe coating operation has been completed, a section of the pipe will be lowered into the ditch. Side -boom tractors may be used to simultaneously lift the pipe, position it over the ditch, and lower it in place. inspection will be conducted to verify: that minimum SikSouth Rockies\Operations - North Piceance\0 County 2-3 January 2008 and local Permits\COA Letters\Hunter Mesa Water Storage FaciliW\Attachment 2\Orchard Unit SWMP 100% cover is provided; the trench bottom is free of rocks, debris, etc.; external pipe coating is not damaged; and the pipe is properly fitted and installed into the ditch. Specialized padding machines will be used to sift soil fines from the excavated subsoil to provide rock -free pipeline padding and bedding. In rocky areas, padding material or a rock shield will be used to protect the pipe. Topsoil will not be used to pad the pipe. At the completion of lowering -in and padding activities the contractor may install trench breakers around the pipelines to minimize subsurface water flow. Details for trench breakers are provided within the BMP Manual (discussed in Section 3.3). 15. Backfilling. Backfilling will begin after a section of the pipe has been successfully placed in the ditch and final inspection has been completed. Backfilling will be conducted using a bulldozer, rotary auger backfill, padding machine or other suitable equipment. Backfilling the trench will use the subsoil previously excavated from the trench. Backfill will be graded and compacted, where necessary for ground stability, by being tamped or walked in with a wheeled or track vehicle. Compaction will be performed to the extent that there are no voids in the trench. Any excavated materials or materials unfit for backfill will be utilized or properly disposed of in conformance with applicable laws or regulations. 16. General Grading. If general grading was conducted to facilitate pipeline construction, these materials will be replaced and graded to recreate the preconstruction topography. Final Reclamation: 17. Cleanup. Cleanup activities will be initiated as soon as practicable after backfilling activities have been completed. All construction -related debris will be removed and disposed of at an approved disposal facility. 18. Subsoil and Topsoil Placement. Subsoil will be evenly re-contoured across the right-of-way to pre -construction conditions. After the subsoil has been re -spread the contractor will spread the previously segregated topsoil back across the right-of-way. The topsoil will be evenly spread to original contours. 19. Vegetation. After any remaining topsoil is spread, the vegetative seed mix will be applied. The area will be revegetated according to private landowner Surface Use Agreements and/or according to the BLM/Forest Service reclamation requirements. Details for revegetation are provided within the BMP Manual (discussed in Section 3.3) and the Revegetation Manual (provided as Appendix B). 20. Application of Erosion Stabilization. Depending on terrain (e.g. steep slopes and drainage crossings) additional measures may be applied to increase stability of the reclaimed area. Possible erosion stabilization methods are provided within the BMP Manual (discussed in Section 3.3). Actual locations and measures used are shown on the Site Plans, which are kept with the Site Specific Records (Volume 2 of the Master SWMP). 2.1.3 Compressor Stations, Treatment Facilities, or Other Facilities. Construction activities for compressor stations, treatment facilities, and other facilities are generally completed in the following sequence: Preconstruction: 1. Surveys. Topographic, vegetation, wildlife and archeology, as dictated. 2. Temporary BMP's. Where physical access is available, installation of terminal perimeter and temporary sediment controls, such as wattles, silt fence and/or other as necessary. Actual BMPs used for each site are shown on the Site Plans, which are kept with the Site Specific Records (Volume 2 of the Master SWMP). S:South Rockies\Operations- North Piceance\0 County and Local Permits\COA Letters\Hunter Mesa Water Storage FaciliN\Attachment 21Orchard Unit SWMP 100 % 2-4 January 2008 Construction: 3. Vegetation Clearing. Vegetation will be cleared/grubbed and placed along the perimeter at the terminal discharge edges/points in a windrow and/or dam beyond the edge of excavation and at any run -on -protection discharge points, and/or chipped or other depending on landowner requirements. 4. Diversions and Retention Reservoirs. After vegetation clearing and prior to topsoil stockpiling, diversion are to be placed for ROP to prevent the greater landscape from discharging onto the planned disturbance. Temporary sediment control BMP's shall be placed at the discharge points of the ROP until permanent erosion controls can be installed along the entire length of the ROP. Diversions are to be installed along the terminal discharge edge inside of the vegetation windrows to convey site water/sediment to terminal discharge points where rough retention reservoirs are to be installed. The retention reservoir outlets are to receive temporary sediment control BMP's until permanent retention reservoirs and erosion, drainage, and sediment BMP's can be installed. 5. Topsoil Stripping/Conservation. All ACCESSIBLE TOPSOIL is to be removed from areas that are to be excavated, covered in subsoils, or turned into stabilized unpaved surfaces. If initial topsoil stockpile areas are insufficient to accommodate the quantities of topsoil being generated, the excess is to be placed at either end of the subsoil stockpile and segregated as much as possible. After major earthwork, grading, and erosion/drainage/sediment controls are complete, any areas that can be identified for immediate interim reclamation shall receive topsoil. 6. General Rough Grading. The site location will be graded to provide suitable surfaces for building sites and vehicle traffic, and may be graded to establish surface drainage patterns, such as berms or roadside ditches as necessary. 7. Excavation. Soil will be excavated to allow for the construction of foundations. Trenches will be excavated for all underground piping and conduit. Excess soil will typically be used in general site grading. 8. Foundation Construction. Foundations will be constructed to support facility buildings. Foundations may consist of select backfill, concrete spread footings, piles, etc. Finished support elevations are to be installed twelve to eighteen inches (12-18") above finished grade or the lowest point of the facility. 9. Facility Construction. Buildings, tanks, processing equipment, etc. will be constructed. Utilities will be installed. Interim Reclamation: 10. Landscaping. If necessary, certain areas will be spread with topsoil and landscaped. 11. Gravel Surfacing. Areas used for access, parking, or materials staging will typically be gravel surfaced. 12. Reclamation of Unused Areas. Areas not needed for facilities, roads, parking, or materials staging will generally be reclaimed. Salvaged topsoil will be spread and the vegetative seed mix will be applied. 13. Application of Erosion Stabilization. Depending on terrain (e.g. steep slopes and drainage crossings) additional measures may be applied to increase stability of the reclaimed area. Possible erosion stabilization methods are provided within the BMP Manual (discussed in Section 3.3). Actual locations and measures used are shown on the Site Plans, which are kept with the Site Specific Records (Volume 2 of the Master SWMP). Final Reclamation: 14. Reclamation of Closed Facilities. When facilities are no longer necessary, the buildings may be demolished, according to approved procedures. All construction materials will be removed and the newly disturbed areas will be reclaimed. Any remaining topsoil will be spread and the vegetative seed mix will be applied. This may occur after termination of this permit and under the coverage of a new construction permit. S:\South_Rockies\Operations - North Piceance\0_ County and Local Permits\COA Letters\Hunter Mesa Water Storage Fachitv\Attachment 2\Orchard Unit SWMP 100% 2-5 January 2008 2.2 Area Estimates The Permit Coverage Area encompasses portions or all of 51 sections of surface land (approximately 32,600 acres) in Township 8 and 9 South, Range 96 and 97 West. Development of the natural gas resource and related facilities within the area is estimated to result in a total disturbance area of 999+ acres. Because the area will vary over time, these are only approximate estimates. This information is used to help determine the extent of control measures (BMPs) needed. 2.3 Description of Existing Topography and Soils The Permit Coverage Area consists of relatively flat mesas and ridge crests, mountainsides and steep canyons with areas of rock outcrop, and valley bottoms. Elevations within the Permit Coverage Area range from approximately 5,000 feet above mean sea level (ems!) along the Colorado River to 6,400 feet near the southeast corner of the area. Annual precipitation within the Permit Coverage Area ranges from 25 to 40 inches. Soils surrounding the Permit Coverage Area are distributed according to the major soil forming factors including climate (effective moisture and temperature), parent material, topographic position, and slope. The soils table within Appendix C provides a summary of the soil types found within the Permit Coverage Area (including permeability, available water capacity, surface runoff, erosion hazard, and others). Most of these soil types are considered to possess moderate to very severe potential for water erosion. 2.4 Description of Existing Vegetation The existing percent vegetative ground cover for each well pad, section of roadway/pipeline, etc. within the Permit Coverage Area is estimated on each inspection and maintenance report form (discussed in Section 5.4), which are kept with the Site Specific Records (Volume 2 of the Master SWMP). The majority of the Orchard Unit consists of pinyon -juniper woodlands. However, there is also a large area of big sagebrush and a smaller area of greasewood fans/flats. The vegetation within the Orchard Unit consists of woodland hillsides dominated by Utah Juniper (Juniperus osteosperma), with a few scattered pinyon pine (Pinus edulis) at higher elevations or north -facing slopes. Drainages and ridge tops/mesas in the Unit (Samson Mesa, Creek Mesa) were dominated by Basin and Wyoming big sagebrush (Artemisia spp.), greasewood (Sarcobatus vermiculatus) and shadscale (Atriplex confertifolia). Drainages in the southeast portion of the project area, as well as high -elevation hillsides, had dense groves of scrub oak (Quercus gambelii) with understory species such as creeping hollygrape (Mahonia repens), mountain pussytoes (Antennaria parvifolia), yarrow (Achellea millefolium), northern sweetvetch (Hedysarum boreale), and sego lily (Calochortus nuttalh). Some patches of serviceberry (Amelanchier alnifolia) and mountain -mahogany (Cercocarpus montanus) were also found along drainage hillsides. The most common understory species found within the sagebrush/greasewood flats included orange globemallow (Sphaeralcea munroana), yellow and red prickly pear cactus (Opuntia polyacantha), cryptantha (Cryptantha glomerate), and yucca (Yucca giauca). The entire Orchard Unit has, to some extent, been affected by cheatgrass (downy brome) (Bromus tectorum) (see Invasive, Non -Native Species). It is often associated with sagebrush communities and disturbed areas, especially two -track roads. In the pinyon/juniper woodlands, this species may be found as the understory. Stressed by the recent drought, many pinyon pine trees in the Colorado Plateau have succumbed to an engraver beetle (Ips confusus) infestation. However, in the Orchard Unit, the scattered pinyon pine trees have shown few signs of infestation. 2.5 Identification of Potential Pollution Sources Potential sources of pollution are associated with all phases of the project from the start of construction though interim reclamation and up until final stabilization has occurred. Final stabilization occurs when construction activities have been completed and all disturbed areas have been either built on, paved, or a uniform S:\South Rockies\Operations - North Piceance\0_ County and Local Permits \COA Letters\Hunter Mesa Water Storage FacilityWttachment 2\Orchard Unit SWMP 100% 2-6 January 2008 vegetative cover has been established with a density of at least 70 percent of pre -disturbance levels, or equivalent permanent, physical erosion reduction methods have been employed. The most common source of pollution during construction is sediment resulting from the erosion of recently cleared and/or graded areas, such as cuUfill slopes and soil stockpiles. However, there may be many potential pollution sources at any given site. The following types of conditions that might affect the potential for a pollutant source to contribute pollutants to stormwater (CDPHE, 2007B) shall be evaluated: • The frequency of the activity (i.e., does it occur every day or just once a month? can it be scheduled to occur only during dry weather?); • Characteristics of the area where the activity takes place (i.e., surface type (pavement, gravel, vegetation, etc.), physical characteristics [site gradients, slope lengths, etc.]); • Ability of primary and secondary containment (fuel tanks, drum storage, etc.) at product storage and loading/unloading facilities to prevent and contain spills and leaks; • Proximity of product storage and loading/unloading facilities to waterways or drainage facilities; • Concentration and toxicity of materials which may to be found in the site's stormwater runoff; and • Contamination of storage facilities/containment with stored materials (i.e., used oil drums or tanks coated with spilled oil). The following items are potential sources of pollutants at the Orchard Unit. Each of the potential sources of pollutants will be controlled using one or more of the following types of BMPs: Erosion Controls, Drainage Controls, Sediment Controls or Non-Stormwater Controls. Descriptions and details for each of these types of BMPs are provided in the BMP Manual (discussed in Section 3.3). Actual BMPs used at each site are shown on the Site Plans (discussed in Section 5.4). Construction: • All Disturbed and Stored Soils: Erosion Controls, Drainage Controls, Sediment Controls. • Vehicle Tracking of Sediments: Sediment Controls, Non-Stormwater Controls. • Management of Contaminated Soils: Non-Stormwater Controls. • Loading and Unloading Operations: Non-Stormwater Controls. • Outdoor Storage Activities (Building Materials, Fertilizers, Chemicals, etc.): Non-Stormwater Controls. • Vehicle and Equipment Maintenance and Fueling: Non-Stormwater Controls. • Significant Dust or Particulate Generating Processes: Non-Stormwater Controls. • Routine Maintenance Activities Involving Fertilizers, Pesticides, Detergents, Fuels, Solvents, Oils, etc.: Non-Stormwater Controls. • On -Site Waste Management Practices (Waste Piles, Liquid Wastes, Dumpsters, etc.): Non-Stormwater Controls. • Concrete Truck/Equipment Washing, Including the Concrete Truck Chute and Associated Fixtures and Equipment: Non-Stormwater Controls. • Dedicated Asphalt and Concrete Batch Plants: There will be no asphalt or concrete batch plants located within the Permit Coverage Area of this SWMP. • Non -Industrial Waste Sources Such as Worker Trash and Portable Toilets: Non-Stormwater Controls. Interim/Final Reclamation: • All Disturbed and Stored Soils: Erosion Controls, Drainage Controls, Sediment Controls. • Vehicle Tracking of Sediments: Sediment Controls, Non-Stormwater Controls. S:\South Rockies\Operations- North Piceance\0 County 2-7 January 2008 and Local Permits\COA Letters Hunter Mesa Water Storage FaciliMAttachment 2\Orchard Unit SWMP 100% • Vehicle and Equipment Maintenance and Fueling: Non-Stormwater Controls. • Significant Dust or Particulate Generating Processes: Non-Stormwater Controls. • Non -Industrial Waste Sources such as Worker Trash and Portable Toilets: Non-Stormwater Controls. 2.6 Allowable Sources of Non-Stormwater Discharge Allowable sources of non-stormwater discharge within the Permit Coverage Area include the following: • Uncontaminated Springs. Although there are several springs within the Permit Coverage Areas, none of these springs are currently located in areas where soil disturbance will occur. If this changes in the future, the controls used at any such location will be noted with the Site Specific Records. • Landscape Irrigation Return Flow. There are several locations where pipelines cross through irrigated fields. These locations will be treated similarly to any water crossing with the use of an appropriate control which will be noted in the Site Specific Records. • Construction Dewatering. Construction dewatering is described and discussed in Section 3.2.5. • Concrete Washout. Concrete washout is described and discussed in Section 3.2.4. • Emergency Fire Fighting Water. Water used to put out any type of fire is considered an allowable source of non-stormwater discharge. No other non-stormwater discharges are allowed under the Stormwater Construction Permit. Other types of non-stormwater discharges must be addressed in a separate permit issued for that discharge. 2.7 Receiving Water Runoff from disturbed areas during construction will be controlled and/or routed through the use of one or more BMPs, as described later in this plan, prior to being discharged to receiving waters. However, it may be expected that runoff from certain areas will infiltrate into the earth and is not expected to contribute to receiving waters. Runoff from the Permit Coverage Area will flow to the Colorado River directly or through one of the following tributaries: Horsethief Creek, Moffat Gulch, Smith Gulch, Alkali Creek, Little Alkali Creek, Wallace Creek, Spring Creek, or other unnamed tributaries. Intermittent drainages occur along Smith Gulch, and Alkali and Little Alkali Creeks. All other drainages are ephemeral. No wetland habitats have been documented along any drainages. However, floodplains occur along Alkali and Little Alkali Creeks. 2.8 Master SWMP Permit Area Map and Individual Stormwater Site Plans An overall Master SWMP Permit Area Map is provided as Appendix D. This map is likely to change constantly and will be updated at least annually. The Master SWMP Permit Area Map includes: • Contours and elevations (topography) with existing drainage patterns; • Locations and names of major surface waters such as streams, wetlands, irrigation ditches, canals, etc....; • Master SWMP permit area boundaries; and • Construction area locations including roads, pipelines, well pads, compressor station facilities, treatment facilities, water parks, and all other facilities. Individual Stormwater Site Plans (Site Plans) of each site (well pad, access road, section of pipeline, etc.) are provided with the Site Specific Records (Volume 2 of the Master SWMP) Separate Site Plans will be S:\South_Rockies\Operations - North Piceance\0 County and local Permits \COA Letters\Hunter Mesa Water Storage FaciliN\Attachment 2\Orchard Unit SWMP 100% 2-8 January 2008 developed for each phase of construction: preconstruction, construction, interim reclamation (if applicable), final stabilization (if applicable) and final reclamation (if applicable). These Site Plans include: • Construction site boundaries (this is the area expected to be disturbed by clearing, excavating, grading, or other construction activities); • Contours and elevations (topography) with existing and proposed drainage patterns; • Limits of well pads and locations of reserve pits and well heads (if applicable); • All areas of ground surface disturbance, including areas of cut and fill; • Locations of all potential pollutant sources listed in Section 2.5 (including areas used for vehicle fueling, the storage of materials, equipment, soil, or waste, etc...); • Locations of all minor surface waters and all anticipated allowable sources of non-stormwater discharge (including springs, dewatering, concrete washout, etc...); • Locations of all existing and planned BMPs (including erosion, drainage, and sediment controls); • Locations, names, and distances to streams, wetlands, irrigation ditches, canals, and other surface waters; and • The size, type and location of any outfall(s). If the stormwater discharge is to a municipal separate stormwater system, name that system, the location of the storm sewer discharge, and the ultimate receiving water(s). Figures showing typical BMP locations along roadways and pipelines are provided as part of the BMP Manual (discussed in Section 3.3). S:\South_Rockies\Operations - North Piceance\0_ County and Local Permits \COA Letters\Hunter Mesa Water Storage Facility \Attachment 2\Orchard Unit SWMP 100% 2-9 January 2008 3.0 Best Management Practices (BMPs) A key component of this Master SWMP is employing BMPs to improve stormwater quality. Local factors will be evaluated to determine what BMPs are suitable and practical at different locations. BMPs will be employed in different combinations during construction activities and phases as conditions warrant. Due to the fact that this Master SWMP is likely to cover more than one ecosystem (as described in Section 2.4), the selection of BMPs (including type, quantity, sequence/combination, etc.) will vary at each site within the Master SWMP Permit Area. Specific BMPs to be employed at each well pad, road, pipeline, or other facility are identified on the Site Plans, which are kept with the Site Specific Records (Volume 2 of the Master SWMP). 3.1 Erosion, Drainage, and Sediment Control BMPs The primary method for controlling erosion, drainage, and sediment transport consists of minimizing initial disturbance of the soil and ground cover. However, many other methods can also be used. All stormwater- related BMPs will fall under at least one of the following three types of controls: • Erosion Control. Any source control practice that protects the soil surface and/or strengthens the subsurface in order to prevent soil particles from being detached by rain or wind, thus controlling raindrop, sheet, and/or rill erosion. • Runoff Control. Any practice that reduces or eliminates gully, channel, and stream erosion by minimizing, diverting, or conveying runoff. • Sediment Control. Any practice that traps the soil particles after they have been detached and moved by wind or water. Sediment control measures are usually passive systems that rely on filtering or settling the particles out of the water or wind that is transporting them prior to leaving the site boundary. BMPs may also be classified as either structural or non-structural controls: • Structural Control. Handles sediment -laden stormwater prior to it leaving each site. Structural BMPs are used to delay, capture, store, treat, or infiltrate stormwater runoff. Some examples of structural BMPs include sediment traps, diversions, and silt fences. Most Runoff Controls and Sediment Controls can also be classified as Structural Controls. • Non-structural Control. Reduces the generation and accumulation of pollutants, including sediment, from a construction site by stabilizing disturbed areas and preventing the occurrence of erosion. Some examples of non-structural BMPs include revegetation, mulching, and surface roughening. These types of stabilization techniques are not only the most effective method for reducing soil loss, but they are also normally the most cost effective due to low initial cost and reduced maintenance requirements. Most, but not all, Erosion Controls can also be classified as Non-structural Controls. The Site Plans, as mentioned previously and kept with the Site Specific Records (Volume 2 of the Master SWMP), show the proposed locations of all erosion, drainage, and sediment control BMPs (both structural and non-structural). Detailed descriptions, design criteria, construction specifications, and maintenance information for all BMPs are provided in the BMP Manual (discussed in Section 3.3). 3.2 Non-Stormwater Control BMPs Non-stormwater controls include general site and materials management measures that indirectly aid in the minimization of water pollution. Types of pollution sources include, but are not limited to, litter, oil and grease, hazardous material spills, and sediment. S:\South Rockies\Operations - North Piceance\0_ County and Local Permits\COA Letters\Hunter Mesa Water Storage Facilityblllachment 2\Orchard Unit SWMP 100% 3-1 January 2008 3.2.1 Materials Delivery and Storage The good housekeeping practices listed below will be followed on site during construction and operation: • An effort will be made to store only enough product required for task completion. • All materials stored on site will be stored in a neat and orderly manner in appropriate containers and, where possible, under a roof or other enclosure, and/or within secondary containment areas to avoid contact with stormwater. • Products will be kept in their original containers with the original manufacturer's label. • Substances will not be mixed with one another unless recommended by the manufacturer. • Whenever possible, all of the product will be used before disposing of the container. • Manufacturer's recommendations for proper use and disposal will be followed. Additional information on material delivery and storage is available in the BMP Manual (discussed in Section 3.3). 3.2.2 Material Handling and Spill Prevention In addition to the material storage practices (listed in the previous section) that will be used to reduce the risk of spills or other accidental exposure of materials and substance, the BMP Manual (discussed in Section 3.3) will provide more detailed information on spill prevention and control. Furthermore, the Spill Prevention, Control and Countermeasure (SPCC) Plan will be followed for the control of hydrocarbons. In general, spill prevention and response procedures will include notification (CDPHE 24-hour spill reporting line — 877-518- 5608), clean-up with the use of spill kits and absorbents, and ensuring that materials and wash water can not discharge from the site, and never into a storm drain system or stream. 3.2.3 Vehicle Cleaning, Fueling, Maintenance, and Tracking Controls As required by EnCana Oil & Gas (USA), Inc. master service agreement(s) and drilling contract(s), contracting companies and/or vendors are required to service all vehicles and equipment prior to entering EnCana facilities. However, in the event maintenance procedures are required at EnCana facilities, all fluids transferred must utilize secondary containment and drip pans to minimize a release of materials and properly dispose or recycle spent materials in compliance with local, state, and federal guidelines. While on site, equipment will be parked, serviced, and fueled within designated areas. Equipment fueling on pipeline rights-of-way will be completed where necessary during active construction. Periodic inspections of equipment and control procedures will be implemented. Selected equipment may be fueled in place using fuel trucks. When necessary, equipment and machinery will be decontaminated at an on-site decontamination area prior to removal from the construction area. Areas will be provided with adequate waste disposal receptacles for liquid as well as solid waste. Vehicle tracking of sediments is not expected to be a problem due to construction scheduling. Construction vehicles will remain on site throughout earth -moving activities. All other vehicles remain in stabilized areas and do not enter the construction area until that area is stabilized. However, applicable BMPs (such as scheduling (to minimize site access), stabilized construction entrances, vehicle cleaning, etc.) will be utilized if sediment tracking does become a problem. In addition to the typical practices listed above, the BMP Manual (discussed in Section 3.3) provides more detailed information on vehicle cleaning, fueling, maintenance, and tracking controls. 3.2.4 Waste Management and Disposal As required by EnCana Oil & Gas (USA), Inc. master service agreement(s) and drilling contract(s), contracting companies and/or vendors are required to manage all waste generated by their activities at EnCana facilities in S:\South Rockies\Operations - North Piceance\0_ County and Local Permits \COA Letters\Hunter Mesa Water Storage Facility\Attachment 2\Orchard Unit SWMP 100 3-2 January 2008 compliance with local, state, and federal guidelines. EnCana Oil & Gas (USA) utilizes a periodic inspection program to ensure waste management requirements are fulfilled and inspections are documented. A few of the waste management procedures that will be followed include the following: • Proper bins will be provided for trash collection and disposal in compliance with local, state, and federal guidelines. • Contaminated soils will be placed into a lined and bermed area. Samples of the impacted soil will be collected and a complete characterization analysis will be performed. When applicable, the impacted soil will be sent to a licensed disposal facility. • The contractor will provide portable toilets. Sanitary waste will be regularly collected by a licensed sanitary waste management contractor and disposed of in an approved manner. • In the event that sediment is inadvertently transported off the construction site, it will be collected and returned to the site and placed on the soil stockpile or spread over the construction pad area and compacted. On well pads and access roads concrete washout is used as an interior conductor pipe ballast. Concrete washout water can NOT be discharged to surface waters or to storm sewer systems without separate permit coverage. However, discharge to the ground of concrete washout water from washing of tools and concrete mixer chutes may be authorized by this permit, provided that (CDPHE, 2007a): 1. The source is identified in the SWMP; 2. BMPs are included in the SWMP to prevent pollution of groundwater; and 3. These discharges do not leave the site as surface runoff or to surface waters. Locations where concrete washout activities take place are shown on the Site Plans. Additional waste management procedures, including solid waste, hazardous waste, contaminated soil, concrete washout, and septic and sanitary waste, are included in the BMP Manual (discussed in Section 3.3). 3.2.5 Dewatering Dewatering refers to the mechanical removal of water from an excavation or other structure. Both groundwater and stormwater may require dewatering during construction. Dewatering of pipelines at the completion of hydrostatic testing will be required for most pipeline installations. 3.2.5.1 Groundwater Dewatering Groundwater is very rarely encountered during the construction activities associated with either E&P sites or Midstream Services sites. If groundwater is encountered, it is typically during construction of a pipeline across a stream crossing. These pipelines are either bored under the stream or a flume is utilized. Non-stormwater construction dewatering of groundwater can NOT be discharged to surface waters or to storm sewer systems without separate permit coverage. However, discharges to the ground of water from construction dewatering activities may be authorized by this permit, provided that (CDPHE, 2007a): 1. The source is groundwater and/or groundwater combined with stormwater that does not contain pollutants in concentrations exceeding the State groundwater standards in Regulations 5 CCR 1002-41 and 42; 2. The source is identified in the SWMP; 3. BMPs are included in the SWMP; and 4. These discharges do not leave the site as surface runoff or to surface waters. S:\South Rockies\Operations - North Piceance\0_ County and Local Permits\COA Letters\Hunter Mesa Water Storage FaciliNWttachment 2\Orchard Unit SWMP 100% 3-3 January 2008 Dewatered groundwater shall be pumped or diverted to a sediment control BMP prior to discharge to the ground. Locations of groundwater dewatering, as well as any BMPs utilized, will be noted on the Site Plans as soon as such dewatering occurs. Additional information on groundwater dewatering is provided in the BMP Manual, discussed in Section 3.3. 3.2.5.2 Stormwater Dewatering The discharge of pumped stormwater (not including groundwater or other non-stormwater sources) from excavations, ponds, depressions, etc., to surface water, or to a municipal separate storm -sewer system is allowed by the Stormwater Construction Permit, as long as the dewatering activity and associated BMPs are identified in the SWMP (including location of the activity), and BMPs are implemented in accordance with the BMP Manual, discussed in Section 3.3 (CDPHE, 2007c). Stormwater that collects in open depressions or trenches during construction activities will be dewatered into an existing sediment control, such as a detention pond, a sediment trap, or simply into a well -vegetated area to percolate into the ground and catch suspended sediment. The quality, source, and location of dewatering, as well as any BMPs utilized, will be noted on the Site Plans as soon as such dewatering occurs. Additional information on stormwater dewatering is provided in the BMP Manual, discussed in Section 3.3. 3.2.5.3 Pipeline Dewatering New Department of Transportation (DOT) pipelines are hydrostatically tested with water upon completion of construction. Once the hydrostatic testing has been completed, dewatering of the pipeline must occur. This will involve the insertion of a displacer, commonly referred to as a pig, in the pipeline. The discharge rate will be regulated, and energy dissipation devices, and/or sediment controls will be used, as necessary, to prevent erosion, streambed scour, suspension of sediments, or excessive streamflow. Locations on pipeline dewatering, as well as any BMPs utilized, will be noted on the Site Plans as soon as such dewatering occurs. Additional information on stormwater dewatering is provided in the BMP Manual, discussed in Section 3.3. 3.3 Stormwater Manual of BMPs A Stormwater Manual of Best Management Practices (BMP Manual) is provided as Appendix E. The BMP Manual has been prepared to provide EnCana personnel, contractors, and subcontractors with information on the proper selection, design, installation, and maintenance of BMPs to manage oil and gas related stormwater and to meet federal and state SWMP implementation requirements. The main objectives of the BMP manual are to: • Serve as an easy-to-use guide for selecting, designing, installing, and maintaining BMPs. • Function as a reference for construction plans and specifications. • Ultimately lead to the avoidance of any net increase in off-site erosion and sedimentation of waters of the U.S. The BMPs within this BMP Manual are organized into four main types of controls for easy reference: Erosion Controls, Runoff Controls, Sediment Controls, and Non-stormwater Controls. Each of these types of controls has been discussed earlier in this section of the SWMP. 3.4 Phased BMP Implementation Various BMPs will be implemented and maintained during different phases of the project. A description of each phase is as follows: • Preconstruction. The preconstruction phase involves the installation of BMPs (temporary and/or permanent) around each site perimeter and at discharge points (such as vegetation buffers (no installation required for this BMP), slash, wattles, diversions, sediment basins and reservoirs, etc...). S13outh Rockies\Operations - North Piceance\0_ County and Local Permits\COA letters\Hunter Mesa Water Storage FaciliMPAtachment 2\Orchard Unit SWMP 100% 3-4 January 2008 • Construction. The construction phase involves the stripping and stockpiling of topsoil, the excavation and backfill for access roads, pipelines, and well pads, and the installation of additional BMPs (preferably permanent BMPs) to control erosion and sedimentation (such as tracking topsoil piles and the installation of roadside channels, culverts, diversions, etc...). • Interim Reclamation. The interim reclamation phase primarily involves seeding of all disturbed areas not needed during operation of the well pads. However, this phase also involves the installation of any additional permanent BMPs that may be needed, as well as the continued maintenance and inspections of all BMPs until final stabilization occurs. Final stabilization occurs once all surfaces are built on, paved or graveled, and/or a uniform stabilized vegetative cover with a density of 70 percent of pre -disturbance levels has been established or when an equivalent permanent, physical erosion reduction method has been employed. A further explanation of final stabilization is provided as section 4 of this plan. • Final Reclamation. For pipelines, this phase involves seeding of all disturbed areas, and the installation of any additional permanent BMPs that may be needed, as well as the continued maintenance and inspections of all BMPs until final stabilization occurs. For other areas (roads, well pads, facilities, etc...), this phase (which may occur after termination of this permit and under the coverage of a new construction permit) occurs when operation of the area is no longer necessary. In these cases, this phase will include the installation of any additional BMPs required during facility decommissioning as well as the spreading of any remaining topsoil, the application of seed, and the inspection/maintenance of all BMPs until final stabilization occurs. Temporary controls, such as silt fencing, may be used to control sediment and erosion during preconstruction and construction activities. Permanent controls, such as diversions and sediment traps, may also be used during the initial phases of the project. However, only permanent controls will be used during interim reclamation and final stabilization. Temporary controls may be converted into permanent controls (such as revegetating a diversion) if needed. The primary control used during interim and final stabilization will be revegetation. Seeding will occur as soon as possible after disturbance of an area is complete. If the seeding is not successful, the area will either be reseeded or other controls will be put in place until reseeding can occur. S:South_Rockies\Operations - North Piceance\0_ County and Local Permits\COA Letters\Hunter Mesa Water Storage FacilitstAttachment 2\Orchard Unit SWMP 100% 3-5 January 2008 4.0 Interim Reclamation and Final Stabilization As soon as practicable after construction activities have been completed in a disturbed area, interim (for well pads, or other facilities) or final (for roads and pipelines) reclamation will be started to prevent further erosion of soil from that area. This typically occurs immediately upon completion of earthwork activities. All disturbed areas (except for the surface of dirt roads, those portions covered by pavement or a structure, and those areas used during operation of a well) will be stabilized with permanent controls. The most common measure used to achieve final stabilization is revegetation. Mulching, erosion control blankets, surfacing with gravel or slash, and/or other methods may also be used. Structural controls (such as diversions, berms, and sediment traps) may be revegetated and used as permanent measures to control pollutants in stormwater discharges that will occur after construction operations have been completed. Appendix E includes detailed information on each of the previously discussed BMPs. In addition, a revegetation manual is provided as Appendix B, which provides guidance as to possible methods and materials needed to accomplish revegetation on differing site conditions. The specific BMPs used at each site are shown on the Site Plans which are kept with the Site Specific Records (Volume 2 of the Master SWMP). Final stabilization means that all ground surface disturbing activities at the site have been completed, and all disturbed areas have been either built on, paved, or a uniform vegetative cover has been established with an individual plant density of at least 70 percent of pre -disturbance levels, or equivalent permanent, physical erosion reduction methods have been employed. For purposes of this permit, establishment of a vegetative cover capable of providing erosion control equivalent to pre-existing conditions at the site will be considered final stabilization. Areas developed as stabilized unpaved surfaces as needed for operation of the facility after interim reclamation, will also qualify as "finally stabilized." This 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 will be prepared in such a way as to prevent ongoing erosion issues. Coverage under the Stormwater Construction Permit may be inactivated for any individual site or a portion/section of that site (i.e. the access road to a well pad) when the area has attained final stabilization and all temporary erosion and sediment control measures associated with that area have been removed. An area will be considered finally stabilized when construction and interim reclamation is complete and when the above final stabilization criteria have been met, even though the site may be disturbed again in the future for final reclamation. However, future land disturbances that follow final stabilization and result in disturbance of one acre or greater (such as final reclamation) will require new permit coverage at that time. Upon final stabilization of any site or portion/section of a site, a signed certification sheet (provided in Appendix F) will be placed into the Site Specific Records binder to replace the Site Plans and the inspection and maintenance records for that area. However, the Site Plans and inspection reports shall be retained in a separate location for a period of three years following final stabilization of the Permit Coverage Area. These documents will be made available to WQCD or EPA upon request and at the time of inspection. S:\South Rockies\Operations - North Piceance\0_ County and Local Permits\COA LettersWunter Mesa Water Storage FacilitytAttachment 2\Orchard Unit SWMP 100% 4-1 January 2008 5.0 Inspection and Maintenance Inspections and maintenance is an extremely important part of the Stormwater Construction Permit. The Construction Manager will ensure that all stormwater management controls are constructed or applied in accordance with governing specifications or good engineering practices. Experienced teams will be used for construction. A first inspection will occur upon installation of the controls. In addition, all workers on the site will be trained as to the location and use of the controls, especially those controls that will be disturbed as construction proceeds across the site. The goal is to minimize the potential for inadvertent removal or disturbance of BMPs and to prevent the off site transport of sediment and other pollutants. 5.1 Inspection Schedule Inspections are required as soon as the first soil disturbance occurs at the site. Once final stabilization of the site has occurred and the EnCana inspector has filled out the final stabilization certification sheet (see Section 4), inspections are no longer necessary. Specific information regarding inspection schedules are provided in the following sections. 5.1.1 Minimum Inspection Schedule for active sites The minimum inspection schedule applies to those sites under active construction, which includes the period from when the ground is initially disturbed to when construction activity is completed, and also includes the preparation of areas that will be revegetated for interim reclamation. During the Active Site period, a thorough inspection of the site stormwater management system (which includes all utilized BMPs) must be conducted at least every 14 calendar days. Also, post -storm event inspections must be conducted within 24 hours after the end of any precipitation or snowmelt event that causes surface erosion. There are three exceptions to the minimum inspection schedule which are described in detail within the next three sections: post -storm event inspections at temporarily idle sites (inspections required within 72 hours after a storm), inspections at completed sites (inspections required monthly), and inspections during certain winter conditions (inspections may not be required). Any use of an exception is temporary, and does not eliminate the requirement to perform routine maintenance due to the effects of a storm event or other conditions that may impact BMP performance, including maintaining vehicle tracking controls and removing sediment from impervious areas. Inspections, as described above, are required at all other times. 5.1.2 Post -Storm Event Inspections at Temporarily Idle Sites Temporarily idle sites are those where there are no construction activities occurring following a storm event. At such sites, post -storm event inspections must be conducted prior to restarting construction activities at the site, but no later than 72 hours following the storm event, and the delay noted in the inspection report. Routine inspections still must be conducted at least every 14 calendar days. 5.1.3 Completed Sites Once construction is completed and the site has been prepared for interim or final stabilization (including completion of appropriate soil preparation, amendments and stabilization practices), the site (or portion of the site) is considered a Completed Site (for purposes of the stormwater permit). Note: only construction activities that result in a disturbance of the ground surface must be completed. Construction activities that can be conducted without disturbance of the ground surface, such as certain well completion activities, would not prohibit a site from otherwise qualifying as a Completed Site. (Completed Sites still require permit coverage until the final stabilization criteria have been met) Completed Sites qualify for a reduced inspection schedule, as the potential for pollution is reduced if the site has been adequately prepared and/or seeded. However, because slopes and other disturbed areas may not be fully vegetated, erosion in these areas still occurs which requires maintenance activities such as regrading S',\South Rockies\Operations . North Piceance\0_ County and Local Permits \COA Letters \Hunter Mesa Water Storage Facilitv\Attachment 2\Orchard Unit SWMP 100 5-1 January 2008 and seeding of problem areas. As such, inspections must continue in order to address these situations. During the Completed Site period, a thorough inspection of the site stormwater management system (which included all utilized BMPs) is required at least once every month. The SWMP must be amended to indicate those areas that will be inspected at this reduced frequency. 5.1.4 Winter Conditions Inspections Exclusion Inspections are not required at sites where construction activities are temporarily halted, snow cover exists over the entire site for an extended period, and melting conditions posing a risk of soil erosion do not exist. This temporary exclusion is applicable only during the period where melting conditions do not exist, and applies to the routine 14 -day and monthly inspections, as well as the post -storm -event inspections. It is typical that when snow cover exists, even at a Completed Site, significant potential for erosion and BMP failure exists when melting does finally occur. Therefore, the site should prepared prior to snow cover to ensure it is as stabilized as possible, and be prepared to perform site maintenance when melt -off occurs, to alleviate any potential problems. Inspection records (see Section 5.4) will document that winter conditions exist and that inspections will be excluded. 5.2 Performing Inspections Inspections will be conducted by qualified personnel on the following areas: • All vegetated areas until 70% of pre -disturbance vegetation levels are reached. • All BMP measures identified in this document. • Construction site perimeter and discharge points. • All disturbed areas. • Areas used for storage of material/waste that are exposed to precipitation. • Other areas determined to have a significant potential for stormwater pollution, such as demolition areas or concrete washout locations, or locations where vehicles enter or exit the site. These areas will be inspected to determine if there is evidence of, or the potential for, pollutants leaving the construction site boundaries, entering the stormwater drainage system, or discharging to state waters. All BMPs will be evaluated to determine if they still meet the design and operational criteria in the SWMP and if they continue to adequately control pollutants at the site. Any BMPs not operating in accordance with Appendix E of this SWMP will be addressed as soon as possible, immediately in most cases, to minimize the discharge of pollutants, and the Site Specific Records will be updated. 5.3 Maintenance Maintenance activities will ensure that all control measures are functioning at optimum levels and that all procedures and techniques will be in proper working order during a runoff event or spill condition. Any maintenance, repairs, or replacements deemed necessary after required inspections will be corrected as soon as possible (if not immediately), to minimize the discharge of pollutants. Certain maintenance procedures may take a short period of time to make sure that all the proper safety precautions are in place, such as a "one call" for utilities, if the maintenance involves excavation of sediment located above a buried pipeline. Maintenance will include, but is not limited to: • Pickup or otherwise prevention of litter, construction debris, and construction chemicals from becoming a pollutant source prior to anticipated storm events. • Removal of sediment from silt fences, sediment traps, and other sediment controls. • Reseeding of any bare spots where vegetation has failed to establish. SitSouth Rockies Operations - North Piceance\0_ County and Local Permits\COA letters\Hunter Mesa Water Storage FacilitvWltachment 2\Orchard Unit SWMP 100% 5-2 January 2006 • Repairs and/or adjustments to any erosion and sediment control that is deteriorating or found to be performing inadequately. Detailed maintenance requirements for each BMP are identified in Appendix E. When maintenance is required, the following process will typically be followed: 1. Perform inspections according to the minimum inspection schedule discussed in Section 5.1. 2. Note the need for maintenance on the inspection and maintenance report form. 3. If necessary, collect the additional materials and/or resources needed to perform the maintenance activity. 4. Perform maintenance and note the date performed on the inspection and maintenance report form. 5. Re -inspect the area to ensure compliance. 5.4 Documenting Inspections and Maintenance The permittee must document inspection results, maintenance activities, and maintain a record of the results for a period of 3 years following expiration or inactivation of permit coverage. A typical inspection and maintenance report form is provided in Appendix G. Although the site may have a phased construction schedule, all construction areas may be inspected at the same time and on one form. Each well pad, road, pipeline, or other facility which is inspected shall be clearly written on the inspection form. Inspection reports will include the following: • Date of inspection, name of inspector, and title of inspector • The area inspected (Site ID), type of area (well pad, access road, pipeline, etc.), phase of construction (preconstruction, construction, etc.), and type of inspection (active, completed, etc.) • Site specific information including disturbed area, soil type(s), ecosystem/vegetation type(s), receiving waters, etc. • Vegetation observations including the percent pre -disturbance vegetation and whether or not vegetation growth has reached 70% of pre -disturbance levels • Specific inspection requirements (all BMPs and areas of potential pollutant sources) • Observed conditions including: - Location(s) of discharges of sediment or other pollutants from the site - Location(s) of BMPs that need to be maintained - Location(s) of BMPs that failed to operate as designed or proved inadequate for a particular location - Location(s) where additional BMPs are needed that were not in place at the time of inspection • Description and date(s) of corrective action(s) taken, and measures taken to prevent future violations • Changes necessary to the SWMP A hand drawn Site Plan shall be included, if necessary, to show the location(s) of any observed condition (as listed above). After adequate corrective action(s) has been taken and recorded, or where a report does not identify any incidents requiring corrective action, the report will contain a signed statement indicating the site is in compliance with the permit to the best of the signer's knowledge and belief.

Examples include, but are not limited to, removal of BMPs, identification of new potential pollutant sources, addition of BMPs, modification of BMP installation/implementation specifications or maintenance procedures, and changes in items included in the Site Plans. Changes to the Master SWMP (Volume 1) shall be noted on the SWMP Revisions log at the front of this plan. Changes to individual site conditions will be noted in the Site Specific Records (Volume 2) on the applicable inspection and maintenance report form. All changes in Volume 1 and Volume 2 shall be made prior to actual changes in the site conditions, except for responsive SWMP changes, which shall be made immediately after changes are made in the field or as soon as practical, but in no case more than 72 hours after the change(s) in BMP installation and/or implementation occur at the site that require development of materials to modify the SWMP. At a minimum, the Master SWMP will be updated annually. The Master SWMP and the Site Specific Records will be retained at the EnCana field office in Parachute during active construction and site inspections to ensure accurate implementation and maintenance of BMPs, and required revisions. These documents will be retained for a period of three years following final stabilization of the Permit Coverage Area.

Dear Sir or Madam: 2717 County Road 215 Suite 100 Parachute, CO 81635 P: (970)285-2739 Please find the attached data summary table and laboratory analysis report for water samples collected from the Hunter Mesa Water Treatment Facility on June 4, 2008.

As such, the water will not come in contact with the general public or with environmental receptors such as soil, ground water, or surface water.

I speak on behalf of numerous neighbors (6500 road Association) regarding these issues. As I will phone with a verbal confirmation of the fax / e-mail itninediately after sending, I respectfirlly ask that they be submitted, in their entirety, to the board of commissioners and public in attendance as a matter of public record. Thank you. As 1 understand it, Encana is prepared to request a special permit allowing for evaporative ponds or lakes on the Fazzi property South of Silt for the purpose of mitigating a surplus of water in the course of gas extraction. I would like to remind the board of commissioners that this type of activity is closely if not directly related to what is known as "coal bed methane" extraction, and has extensively documented, negative impacts to water quality and water tables. As there is relative certainty as to the negative impacts to our local water supply, and in light of the recent and potentially repeated drought conditions of 2002, I feel that this issue is one which should be studied at length and will most certainly be an issue for review by the State Water Board and Environmental Protection Agency. 1, therefore, respectfully request denial or a moratorium of any such permit to conduct this or similarly designed endeavors. 00 a separate but related note, I would like to present an issue of ivanrediate and extreme concern regarding the use of County Road 331 (South of Silt) as a designated truck route. Eighteen wheelers, such as are utilized by the ranching and oil and gas industry pose an itnminent threat to human health safety and welfare. Encana has not submitted a request to Garfield County Road and Bridge Department for a permit to travel an extended portion of 331 Road. I am particularly concerned for the safety of our school children who travel said roadway to and from school every week -day. There are two blind corners and a blind hill along this road, one specific corner, of which requires immediate attention by the county in order to facilitate safe passage under even the most ordinary of conditions. I would like to remind the board of commissioners that a woman died, through no apparent fault of her own, in the late fall of 2001, due in great part to a dangerously reduced line of site and negligent driver. Had her line of site been adequate, she may have been able to take other measures. however, as there is little alternative than a full -on impact, either way - it is doubtful that her unfortunate circumstance would have been different. JAN -06-03 MON 07:29 From Lisa Bracken 01-06-03 Page 2 of 2 307576 2146 P.02 Let us not think the unthinkable with regard to our children. Provide them safe passage. Prohibit the use of industrial vehicles on this road, and do the right thing by correcting these unconscionable dangerous conditions. It now appears that a well site is being pursued on the Monkewich property which also abuts county road 331, near an active bus stop. Please consider the exacerbated dangers which could be involved and the certain interest the Colorado Department of Transportation would express under such circumstances. I submit this quote taken from an 85 -page report produced jointly by the International Petroleum Industry Environmental Conservation Association (IPIECA) and the International Association of Oil & Gas Producers (OGP). "In concentrating on securing future supplies of oil and gas, we have perhaps paid less attention to other, equally important aspects of our business. We readily acknowledge that as individual companies - and as an industry - we do not always have the right answers. Sometimes we do not even ask the right questions. Therefore, probably the biggest challenge we face is in working more closely and effectively with others; listening to and learning from diverse points of view,' the report says." 1n light of such a statement, I ask that you, as our county leaders take the initiative in hearing with an open mind the concerns of your constituency. These issues are close to our heart, and we believe that as our neighbors, they are close to yours as well. Let us pause (for as long as it may take), ponder and work cohesively as we approach these uncertain issues. Let us not be dictated to by industry interest. Let us, instead, discover the questions and answers together - and implement solutions as a caring and sustainable community. Sincerely sa Bracken c.c.

(EnCana) currently operates natural gas wells in Garfield County. These wells produce brackish water commonly referred to as produced water. This produced water is alkaline and must be disposed of properly. The rate that a natural gas well generates produced water is variable but historical rates have averaged approximately 2.5 barrels per day. Produced water is also generated during the drilling and completion of a natural gas well. It is sometimes necessary to truck several hundred barrels of water from a drill site after completion of a well. At an individual well any oil and/or natural gas is separated from the produced water generated by the well. The water is typically stored in an 80 -barrel capacity tank at the well location and then intermittently loaded onto a tank truck and hauled off site. The primary non -water component of the produced water is sodium chloride. Traces of other salts such as magnesium chloride and sodium bicarbonate are also present. The produced water contains an average of 10,000 parts per million total dissolved solids. This level of salinity is beyond potable but still far lower than that of seawater. Produced water also contains trace amounts of free and dissolved oil. EnCana (and formerly Snyder Oil) has operated an evaporation pit near Rifle since 1996. The capacity of this evaporation pit is no longer adequate. EnCana intends to construct an additional evaporation pit next to their Hunter Mesa Booster Station south of Rifle. The Hunter Mesa facility will be constructed somewhat differently than the Rifle evaporation pit. The new facility will be equipped with extra measures to prevent oil from reaching the evaporation pond. The off-load water tanks will be plumbed in series with internal weirs and most of the oil will be separated and contained at this point. Water discharged from the off-load tanks will then pass through a gas powered heater in which any oil that may carry over from the tanks will be separated and contained. The heater also increases the water temperature thereby increasing the evaporation rate. The majority of water that passes through the new facility will not be evaporated but will be purified and reused in EnCana hydro fracturing operations. Approximately three quarters of the production water will exit the heater system into a state of the art electronic water treatment system. The electronic water treatment system will lower the Total Dissolved Solids (TDS) to well below 3,000 parts per million (ppm) and this treated water will be stored in a separate Low TDS pond. EnCana personnel will pull water form the Low TDS pond as needed for hydro fracturing. The new facility would operate similarly to the existing pond where the produced water will be sprayed over the pond to increase the evaporation rate. A series of center -mounted sprinklers will distribute the water over the pond in droplets. The droplets will be small enough to maximize evaporation while not creating a mist, which would tend to drift. The anticipated total rate of spraying is approximately 500 gallons per minute. The sprinkler lines will be charged utilizing a 460 C.I. motor powering a Berkley 3/8 pump. The pump and distribution lines will be situated within the lined area so that in the event of a leak the water will be contained. EXHIBIT "B" IMPACT STATEMENT HUNTER MESA STATION EVAPORATION PIT ADDITION The location for the new facility was selected for a number of beneficial reasons. The proposed location is central to Encana operations in the area. This will shorten truck trips and reduce the number of trucks traveling closer to town The evaporation facility will not differ significantly from the surrounding land uses, which are oil and gas related. The location is relatively remote. The closest residence is over 1 mile southeast of the site therefore sufficient distance exists to prevent noise or odor impacts to surrounding properties. The hours of operation for the facility will be as such: the evaporation system pump and sprayers will operate 24/7 during the spring and summer months and will be purged and shut down for the fall and winter months; the electronic water treatment system and heater treater will operate 24/7/365. The majority of water trucks will travel to and from the site between 8 am and 4 pm but some trips may be made outside of these hours if needed. At maximum usage the facility is expected to generate approximately 20 to 25 water tanker truck trips per day into and out of the new facility. The majority of these trips will be on existing private roads that already service natural gas operations on Hunter Mesa. Water trucks will operate primarily during daylight hours and will be traveling to and from well locations in the area. Heavy trucks already frequently travel the roads in the Hunter Mesa area therefore the new facility is not expected to require improvements to the existing roads. At present EnCana hauls produced water to their evaporation pit on 319 Road just south of Rifle, as well as to the Black Mountain disposal facility in Mesa County. The new facility will reduce the number of trips to the present evaporation facility therefore keeping the majority of EnCana related truck traffic farther from town. During the evaporation process an estimated 2 percent of the spray is lost to driftage. The saline nature of the produced water can potentially impact vegetation on surrounding lands. The driftage also has a noticeable odor but as long as the driftage is contained the odor is also contained. The new facility will contain this driftage with a berm, approximately 20 feet tall and 60 feet wide at its base, on the downwind sides of the pit. Noise will be emanated by the aeration pump and sprayers. The containment berm will aid in mitigating this noise as well as controlling driftage. The sound level of noise emanating from the facility will not exceed the 75 decibel maximum set forth in Colorado Statute 25-12-103. Given the remote location of the new facility, noise or odor will not be a nuisance. If in the unlikely event nuisance noise or odors are emanated by the facility extra measures will be taken to control them. The location of the proposed Hunter Mesa facility is underlain by gravels and alluviums derived mainly from sandstone, shale or basalt. The predominate soil type in the site area is clayey loam. This facility is designed to protect the groundwater resources. The pits will be lined with impermeable HDPE and if groundwater is encountered during construction, monitoring wells will be installed and sampled regularly. There will be no use of either groundwater or natural surface water on the facility. The facility design will preclude any pollution to enter surface run-off. There will be no sewage generated on the site. The unloading and tank area will be constructed in accordance with US EPA Spill Prevention Control and Countermeasures Plan requirements. As such, secondary containment or diversion structures will be constructed to prevent any release from leaving the facility. The property boundary, as depicted on the Site Layout Map, will be surrounded by 8 -foot tall field fence (wood posts with wire mesh panels). Fencing will contain two steel access gates and cattle guards will be installed at both gates. The gates will remain open during daylight hours and will be secured overnight. This type of fencing will be sufficient to preclude wildlife entry. Surrounding uses are such that a visible barrier fence should not be necessary. Signage will include the company name and address as well as a 24-hour toll-free emergency phone number. The facility will occupy eight acres of rangeland considered to be winter rangeland for mule deer. This type of facility is by nature incompatible with continued wildlife access therefore wildlife will be excluded by wildlife -proof fencing. The limited size of the facility will not block wildlife migration routes. An oil separating system will be employed to prevent oil from reaching the holding pond in order to eliminate potential impacts to waterfowl. Attraction of waterfowl to the holding pond is not expected but a deterrence system will be installed if waterfowl usage does occur. The facility will utilize three sizes of steel above ground holding tanks. Three 400 -barrel (bbl) capacity tanks, 12 ft in diameter by 20 ft high, will hold the production water offloaded from the water trucks. Five 300 bbl capacity tanks, 12 ft in diameter by 15 ft high, will hold water or oil from the heater treater separator system. One 210 bbl capacity tank, 10 ft in diameter by 15 ft high, will capture overflow from the other tanks. All tanks will be painted in a beige color to match the surrounding terrain. A minimal amount of lighting will be required for the new facility therefore four 175 -watt mercury vapor lamps will be installed. These lamps can be set to turn on automatically at dusk and tum off at sunrise. Two lamps will be mounted on the east side of the tanks in order to light the offloading area and two lamps will be mounted on the west boundary to light the ponds for safety purposes. Three phase electrical power services the compressor station adjacent to the proposed facility therefore upgrades to existing electrical utilities will not be necessary. The expected life of the Hunter Mesa Evaporation Pit is 20 years. Reclamation of the facility would include regrading the facility to the approximate existing slope, replacing stockpiled "topsoil" and seeding with the seed mix of the current land manger's choice. Construction of the facility is expected to take approximately 10 weeks to complete.

Each off-load water tank will be plumbed with internal weirs allowing the oil that floats to the top to be skimmed off and contained in a separate tank. The relatively oil -free water will be discharged from the off- load tanks into a heat -treating system. The "heater treater" will remove remaining oil before the water reaches the evaporation pit. The manufacturer and model of heater treater has not yet been determined but the unit will be constructed to industry standards. The model selection will be based on acceptable throughput capacity while operating at the lowest possible temperature to achieve the desired separation of water and oil. The electronic water treatment system is manufactured by Sabrex of Texas, Inc. This new system will allow EnCana to recycle approximately three quarters of their produced water. Once the produced water is treated with the Sabrex system EnCana will use the water in their hydro fracturing operations. The Sabrex system is described on the following three pages.

For years Reverse Osmosis and DI have been used to remove total dissolved solids from water and wastewater. Today the high energy requirements, use of hazardous chemicals for cleaning and regeneration requirements, complexity of pretreatment requirements and high volumes of waste reject/regeneration water are coming under attack by regulatory agencies in commercial and industrial applications. There is also a growing requirement to recycle water due to NPDES permitting restrictions or other regulatory compliance requirements. There is new electronic water purification (EWP) technology that can offer an alternative to traditional water purification. How Does it Work? There is no comparable technology on the market today and is marketed under the EWP brand name by Sabrex and Alamo Water Refiners. Various Dissolved salts and Silica in water are the major components of TDS (total dissolved solids). These dissolved salts need to be removed on many applications, or they will form deposits and affect equipment performance. (Figure 1) Figure 1 Figure 2 Figure 3 The Electronic Water Purifier makes patented technology available to generate DI quality water by removing these dissolved salts electronically. Electrodes used are made from activated carbon fabric and a conductive material. When these electrodes are layered using a DC power supply, the individual electrodes are charged with different polarities. The dissolved salts in the water have polarity charges are attracted to the opposite polarity of the electrode, thus removing the dissolved salts from the water. These dissolved salts are adsorbed electrochemically on the activated carbon electrode surface creating the pure water. (Figure 2) When sufficient dissolved salts are deposited on the electrodes and conductivity increases beyond the set point desired, the electrodes are regenerated by shorting the electrodes to ground. The http://sabrex-tx.com/report2.htm 11/22/2002 Sabrex of Texas - Electronic Water Purifier Page 2 of 3 contaminants fall off the electrode in the same chemical form as was removed. After the regeneration, the waste at 5 to 10 times the original concentration is discharged through a valve to drain. (Figure 3) Upon completion of this cycle, the polarities are reversed for normal operation. The principal of first order kinetics applies, since the same percentage of dissolved solids is removed regardless of whether the feed stream is 500 PPM or 2,000 PPM. Only the run time is affected. The limit on TDS is 2,500 PPM with this carbon fiber based material. In the future carbon powder based technology is being developed that will safely operate at TDS levels of 15,000 PPM. Pretreatment is not a major issue, since the factors that affect membranes and resin such as suspended solids, chlorine and organics do not affect the electrodes of the EWP. Also the electrodes do not allow bacteria to breed and colonize. Cycle Testing Much testing has been done on San Antonio City Water for over 1,000 cycles (Figure 4). Consistently, based on a volumetric average over 75% of the dissolved salts in the water were removed through one pass through the electrode at 1 gpm over a duration of more than 2 hours. The regeneration time per cycle was Only 15 minutes. Only 1.7 watt-hours of electricity are used per gallon of water purified. 1 1 UC Power Supply Figure 4 San ant 9511 aaa 536 o.x3R -TOO P testing of sn 0005 ty Water 24 hrsfday o, ER Time of100 Rurb ni I5R $arias 2 5krwa 5 Selo. 4 ---+ S9r6Ps5 ..A+w Setles 6 -y— 500051 Strips e 84008 50851610 Simplex Process Flow Schematic Electrode Flowmeter 1 '• wastewaer Pure water The process uses a PLC to control all functions such as regeneration using the conductivity set point to initiate the opening and closing of solenoid valves.

The pan evaporation rate is estimated to be approximately 45 inches from which the average annual precipitation of 14 inches must be subtracted. The net evaporation rate is therefore 31 inches. Doubling 31 inches of evaporation yields a 62 -inch evaporation rate utilizing spray aeration. The surface area of the evaporation pit is approximately 1.8 acres, which is expected to yield an evaporation rate of approximately 9.3 acre feet/year. 9.3 acre ft/year is equivalent to 72,153 bbls/year or 198 bbls/day. EXHIBIT "IC" LINER INSTALLATION PROCEDURES HUNTER MESA STATION EVAPORATION PIT ADDITION 2.2.2 Storage The Project Manager shall provide storage space in a, location (or several locations) such that on-site transportation and handling are minimized. Storage space should be protected from theft, vandalism, passage of vehicles, and be adjacent to the area to be lined. INSTALLATION 3.1 Anchor Trench Systems All Anchor Trench Systems shall be excavated by the Earthwork Contractor (unless otherwise specified) to the lines and widths shown on the design drawings, prior to geomembrane placement. If the anchor trench is excavated in clay susceptible to desiccation, no more than the amount of trench required for the geomembrane to be anchored in one day shall be excavated (unless otherwise specified) to minimize desiccation potential of the anchor trench clay soils. Slightly rounded corners shall be provided in the trench where the geomembrane adjoins the trench so as to avoid sharp bends in the geomembrane. No large rocks or clay lumps shall be allowed to underlie the geomembrane in the anchor trench. Backfilling of the anchor trench shall be conducted in accordance with Section 3.5. 3.2 Geosvnthetic Placement Immediately prior to installation of the designed geomembrane liner, the surface shall be observed by CLC and the owner or the owner's representative. The decision to repair cracks, if any, shall be made only by the Project Manager. The subgrade shall be walked by CLC and the Project Manager for joint approval. CLC will sign acceptance of the surface condition of the subgrade. The integrity of the underlying soil is the responsibility of the owner/earthwork contractor. Subgrade Preparation Recommendations: No liner shall be placed on surfaces not previously found acceptable by the CLC supervisor or his agent. No sharp stones or other hard objects that could penetrate the liner shall be present in the top 1 inch of the surfaces to be covered. Surfaces to be lined shall be smooth and free of all rocks, sharp stones, sticks, roots, sharp objects, or debris of any kind. The surface should provide a firm, unyielding foundation for the geosynthetic with no sudden, sharp or abrupt changes or break in grade. 3.2.1 Field Panel Identification A field panel is the unit of geomembrane which is to be seamed in the field; i.e., a field panel is a roll or a portion of roll cut in the field. At the time of installation, the CLC Field Supervisor shall give each field panel an "identification code" (Number or letter -number). This identification code shall be agreed upon by the Project Manager. This field panel identification code shall be as simple and logical as possible. 5 3.2.2 Field Panel Placement 3.2.2.1 Location Field Panels are located by the CLC Field Supervisor in a manner consistent with the Specification and best suited to existing site conditions. • 3.2.2.2 installation Schedule Field panels are placed one at a time, and each field panel is seamed immediately after its placement (in order to minimize the number of unseamed field panels); and CLC shall record the identification code, location, and date of installation of each geomembrane field panel. Daily Progress Report to be submitted to Project Manager for forwarding to Engineer (Owner), also on a daily basis. 3.2.2.3 Weather Conditions Welding placement shall not take place during any precipitation, in the presence of excessive moisture, blowing dust, or in the presence of excessive winds (unless wind barriers are provided). In addition, welding shall not take place in an area of ponded water. 3.2.2.4 Method of Placement CLC shall verify the following: Any equipment used does not damage the geomembrane by handling, trafficking, excessive heat, leakage of hydrocarbons, or other means; The prepared surface underlying the geomembrane has not deteriorated since previous acceptance and is still acceptable immediately prior to geosynthetic placement; Any geosynthetic elements immediately underlying the geomembrane are clean and free of. debris; All personnel working on the geomembrane do not smoke, wear damaging shoes, or engage in other activities which could damage the geomembrane; The method used to unroll the panels does not cause scratches or crimps in the geomembrane and does not damage the supporting soil; The method used to place the panels minimizes wrinkles (especially differential wrinkles between adjacent panels; Adequate temporary loading and/or anchoring (e.g., sand bags, tires), not likely to damage the geomembrane, has been placed to prevent uplift by wind (in case of high winds, continuous loading, e.g., by adjacent sand bags, or soil is recommended along edges of panels to minimize risk of wind flow under the panels); Direct contact with the geomembrane is minimized; i.e., the geosynthetic(s) are protected by geotextiles, extra geomembrane, or other suitable materials in areas where excessive traffic may be expected. 6 The electric generator is placed on a smooth base such that no damage occurs to. the geomembrane; Buffing shall be completed no more than one (1) hour prior to extrusion welding (buffing is not necessary for hot wedge welding); A smooth insulating plate or fabric is placed beneath the hot welding apparatus after usage; and The geomembrane is protected from damage in heavily trafficked areas. 3.3.3 Seam Preparation CLC shall verify that: Prior to seaming, the seam area is clean and free of moisture, dust, dirt, debris of any kind, and foreign material; and Seams are aligned with the fewest possible number of wrinkles and "fishmouths". 3.3.4 Weather Conditions for Seaming The normally required weather conditions for seaming are as follows: The high temperature limit for welding is the temperature at which the well-being of the crew becomes uncertain. Unless authorized in writing by the Project Manager, no seaming shall be attempted at ambient temperatures below 50 Fahrenheit. The colder the weather, the slower the welding speeds possible for effective welding. Further detail for cold weather welding follows in this section. In all cases, the geomembrane shall be dry and protected from wind. CLC shall verify that these weather conditions are fulfilled and will advise the Project Manager if they are not. The Project Manager shall then decide if the installation shall be stopped or, postponed. Cold Weather Seaming of Polyethylene Liners Cold Weather welding restrictions exist because problems associated with hot air seaming techniques have been mistakenly applied to extrusion welds. The CLC extrusion weld, however, has been successfully employed in cold weather on several job sites. With the assistance of preheating the sheet, the CLC weld has been applied as low as -50F. Both the CLC extrusion weld and hot wedge weld are able to overcome cold weather welding restrictions because of their unique designs. CLC's extrusion weld is not solely temperature dependent. It combines pressure, extrudate, and mixing action in addition to temperature, to bond the liner together. The mixing action means that convective heat transfer takes place in addition to conductive heat transfer. Overall heat transfer is thus improved, and sensitivity to ambient temperature is dramatically reduced. - 3.3.6 General Seaming Procedure Unless otherwise specified, the general seaming procedure used by CLC shall be as follows: The rolls of geomembrane shall be overlapped by approximately four inches (100 mm) for fusion welding and three inches for extrusion welding. "Fishmouths" or wrinkles at the seam overlaps shall be cut along the ridge of the wrinkle in order to achieve a flat overlap. The cut "fishmouths" or wrinkles shall be seamed and any portion where the overlap is inadequate shall then be patched with an oval or round patch of the same geomembrane extending a minimum of 6 inches beyond the cut in all directions. Seaming shall extend up the panels and well into the anchor trench. All cross seams are to be extrusion welded where they intersect. The top flap of membrane is removed in the area to be extrusion welded and the weld area is ground parallel to the seam prior to welding. For fusion welding on wet or muddy subgrade, a movable protective layer of plastic may be required to be placed directly below the overlapped membranes being seamed. This is to prevent any moisture buildup between the sheets to be welded and/or to provide consistent rate of speed for the wedge welding device. 3.3.7 Nondestructive Seam Continuity Testing 3.3.7.1 Concept CLC shall nondestructively test all field seams over their full length using a vacuum test unit, air pressure testing, or other approved method. The purpose of nondestructive tests is to check the continuity of seams. It does not provide information on seam strength. Continuity testing shall be carried out as the seaming work progresses, not at the completion of all field seaming. 3.3.7.2 Vacuum Testing The equipment shall be comprised of the following: - A vacuum box assembly consisting of a rigid housing, a. transparent viewing window, a soft neoprene gasket attached to the bottom, port hole or valve assembly, and a gauge to indicate chamber vacuum; A steel vacuum tank and pump assembly equipped with a pressure controller and pipe connections; A rubber pressure/vacuum hose with fittings and connections; A bucket and wide brush, mop or spray assembly; A soapy solution. 10 Insert needle or other approved pressure feed device into the tunnel created by. the fusion weld; Energize the air pump to a pressure between 25 and 30 psi (160 and 200 kPa), close valve, and sustain pressure for approximately five (5) minutes; If loss of pressure exceeds above listed values, or does not stabilize, locate faulty area and repair in accordance with Section 3.4; Remove needle or other approved pressure feed device and seal; and Pressure tested seams are recorded on Daily Progress Reports. 3.3.8 Destructive Testing 3.3.8.1 Concept Destructive seam tests shall be performed at random selected locations. The purpose of these tests is to check that welds are fully integrated with each other and to evaluate seam strength. Seam strength testing shall be done as the seaming work progresses, not at the completion of all field seaming. 3.3.8.2 Location and Frequency The owner and/or owner's representative shall select locations where seam samples will be cut. These locations shall be established as follows: A frequency shall be agreed upon by CLC and the Project Manager at the Resolution and/or Pre -Construction Meeting. Unless otherwise specified, destructive samples should be pulled at intervals of 1 sample for every 500 linear feet of weld. The seaming technician shall not be informed in advance of the locations where the seam samples will be taken. 3.3.8.3 Sampling Procedure Samples shall be cut by CLC as the seaming progresses in order to have test results before the geomembrane is covered by another material. CLC shall: Cut samples; Assign a number to each sample which is to be based upon seam and sample number and mark it accordingly; Record sample location on daily report; and All holes in the geomembrane resulting from destructive seam sampling shall be immediately repaired in accordance with repair procedures described in Section 3.4. The continuity of the new seams in the repaired area shall be tested according to Section 3.3.7. 12 Type of Material Specification for Seam Strength (Based on NSF 54 Standards) No. of Coupons Minimum Values Required (Pounds per Inch of Width) Peel Peel Shear Shear Peel Shear Extrusion Fusion Extrusion Fusion 30 mil HDPE 2 1 35 49 63 63 40 mil HDPE 2 1 48 67 86 86 60 mil HDPE 2 1 70 98 126 126 80 mil HDPE 2 1 92 115 166 166 100 mil HDPE 2 1 115 143 207 207 30 mil HDT 2 1 31 44 56 56 40 mil HDT 2 1 42 60 76 76 60 mil HDT 2 1 63 88 113 113 80 mil HDT 2 1 84 115 151 151 100 mil HDT 2 1 105 143 189 189 Standard testing procedure is as follows: If there is a failure in either peel or shear, then five total coupons are tested. If more than one coupon fails, then the sample fails. This is a modified ASTM method. The ASTM methods that are used are D4437, D413 and D638 which all can apply. Reasons for pass/fail criteria: The FTB requirement is very important. With a fully integrated, continuous connection through the seam, no weld bead/sheet or sheet/sheet interface exists. Such an interface might be separated by absorbed chemicals, causing failure of the seam. In addition to the FTB criterion, a minimum stress level is specified. This is important in order to protect against legitimate tearing of a thin portion of polymer in the weld (as might occur if the weld is off center). The minimum stress levels are necessarily lower than tensile yield strengths of the parent sheet because of the different configuration of the test specimens during destructive testing. Bending moments come into play along with straight tensile stresses, especially as the sheets are bentback in peel. These bending moments depend on the shape of the welds which vary even within the same welding technique. The minimum stress values are based on the average performance values of passed weld specimens tested in the laboratory. 3.3.8.6 Procedures for Destructive Test Failure The following procedures shall apply whenever a sample fails a destructive test. CLC has two options: 1) Reconstruct the seam between any two passed test locations; or 14 Topping - used to repair areas of inadequate seams which have an exposed edge; In addition, the following provisions shall be satisfied: Surfaces of the geomembrane which are to be repaired shall be abraded no more than one hour prior to the repair; All surfaces must be clean and dry at the time of the repair; All seaming equipment used in repairing procedures must be approved; The repair procedures, materials, and techniques shall be approved in advance of the specific repair by the Project Manager and CLC. Patches or caps shall extend at least 6 inches beyond the edge of the defect, and all corners of patches shall be rounded with a radius of at least 3 inches. 3.4.3.2 Geomembrane Verification of Repairs Each repair shall be non-destructively tested using the methods described in Section 3.3.7 as appropriate. Repairs which pass the non-destructive test shall be taken as an indication of an adequate repair. Failed tests indicate that the repair shall be redone and retested until a passing test result is obtained. 3.5 Backfilling of Anchor Trench The anchor trench, if any, shall be adequately drained by Owner/Earthwork Construction to prevent ponding or otherwise softening the adjacent soils while the trench is open. The anchor trench shall be backfilled by the Earthwork Contractor or as outlined in the specifications and bid documents. Since backfilling the anchor trench can affect material bridging at toe of slope, consideration should be given to backfill the liner at its most contracted state; preferably during the cool of the morning or extended period of overcast skies. Care shall be taken when backfilling the trenches to prevent any damage to the geosynthetics. 3.6 Lining System Acceptance The geosynthetic lining system shall be accepted when: The installation of all materials are deployed and welded; Verification of the adequacy of all seams and repairs including associated testing is complete. 3.7 Soils in Contact with the Geomembrane Important points for quality assurance of soils in contact with the geomembranes include: A geotextile or other cushion approved by the designer may be installed between angular aggregate and the geomembrane. Equipment used for placing soil shall not be driven directly on the geomembrane. 16 Property Thickness.

This deep, well drained, moderately sloping soil is on mesas, bench- es, and sides of valleys. Elevation ranges from 5,000 to 7,000 feet. This soil formed in alluvium derived from sandstone, shale, or basalt. The average annual precipi- tation is about 14 inches, the average annual air tem- perature is about 46 degrees F, and the average frost - free period is about 120 days. Typically, the surface layer is brown loam about 4 inches thick. The subsoil is reddish brown clay loam about 24 inches thick. The substratum is pinkish white loam to a depth of 60 inches. Included with this soil in mapping are small areas of Olney, Kim, and Ildefonso soils that have slopes of 3 to 6 percent. These areas make up 10 to 15 percent of the map unit. Permeability is moderate, and available water capacity is high. Effective rooting depth is 60 inches or more. Surface runoff is slow, and the erosion hazard is moder- ate. This soil is used mainly for irrigated crops and hay and for dryland farming (fig. 10). Alfalfa, small grains, and grass -legume hay are grown. Small areas are used for grazing. These soils are usually irrigated by flooding. Drop structures in irrigation ditches, grassed waterways, and minimum tillage prevent serious erosion. Irrigation water should be carefully managed to avoid piping and erosion. Cover crops or stubble mulching also help to limit ero- sion in dryfarmed areas. The native vegetation on this soil is mainly wheat - grass, needleandthread, and sagebrush. When range condition deteriorates, forbs and shrubs increase. When the range is in poor condition, undesira- ble weeds and annual plants are numerous. Properly managing grazing maintains and improves range condi- tion. Reducing brush improves the range. Seeding im- proves range in poor condition. Crested wheatgrass, western wheatgrass, and Russian wildrye are suitable for seeding. Preparing a seedbed and drilling the seed are good practices. Pheasant, mourning dove, cottontail rabbit, some mule deer, and squirrel find habitat on this soil. Community development and recreation are limited by low strength and the shrink -swell potential. Dwellings and roads can be designed to overcome these limita- tions. Community sewage systems will be needed if the population density increases.

These gently sloping to rolling soils are on mesas and sides of valleys. Elevation ranges from 5,000 to 6,500 feet. The Potts soil formed in alluvium derived from sandstone, shale, or basalt. The Ildefonso soil formed in very strongly calcareous, basaltic alluvium and small amounts of eolian material. The average annual precipitation is about 14 inches, the average annual air temperature is about 46 degrees F, and the average frost -free period is about 120 days. The Potts soil makes up about 60 percent of the map unit, and the Ildefonso soils makes up about 30 percent. The Potts soil is on slightly concave positions, and the Ildefonso soil is on the breaks of steeper slopes. The Potts soil is deep and well drained. Typically, the surface layer is brown loam about 4 inches thick. The subsoil is reddish brown clay loam about 24 inches thick. The substratum is pinkish white loam that extends to a depth of 60 inches. RIFLE AREA, COLORADO Permeability of the Potts soil is moderate, and availa- ble water capacity is high. Effective rooting depth is 60 inches or more. Surface runoff is slow, and the erosion hazard is moderate. The lldefonso soil is deep and well drained. Typically, the surface layer is brown stony loam about 8 inches thick. The underlying material is white, calcareous very stony loam that extends to a depth of 60 inches. Permeability of the lldefonso soil is moderately rapid, and available water capacity is low. Effective rooting depth is about 60 inches. Surface runoff is slow, and the erosion hazard is moderate. Included with this soil in mapping are small areas of Olney and Kim soils that have slopes of 3 to 12 percent. These areas make up 5 to 15 percent of the map unit. These soils are used mainly for limited grazing and wildlife habitat. The native vegetation on the Potts soil is mainly wheatgrass, needleandthread, and sagebrush. The native vegetation on the Ildefonso soil is mainly pinyon and Utah juniper and an understory of Indian ricegrass, wheatgrass, junegrass, serviceberry, bitterbrush, and sa- gebrush. When the understory vegetation deteriorates, grasses almost disappear and forbs and shrubs increase. Proper- ly managing grazing maintains and improves range con- dition on both soils. Seeding improves range on the Potts soil if it is in poor condition. Crested wheatgrass, western wheatgrass, and Russian wildrye are suitable for seeding. Preparing a seedbed and drilling the seed are good practices. Reducing brush on the Potts soil im- proves the range. Properly managing the vegetation on the lldefonso soil maintains wood production and graz- ing. Selectively thinning pinyon and juniper improves grazing and provides firewood, posts, and Christmas trees. The lldefonso soil is suited to production of pinyon and Utah juniper. It can produce 9 cords of wood per acre when trees more than 4.5 feet tall reach an average diameter (at one foot) of 5 inches. The low available water capacity affects survival of tree seedlings. Mule deer, wild turkey, chukar, gray squirrel, cottontail rabbit, and some pheasant find habitat on these soils. Community development is limited on the Potts soil by low strength, shrink -swell potential, and slope. Communi- ty development is limited on the lldefonso soil by steep slopes. This complex is in capability subclass Vle, nonirrigated. 58—Potts-lldefonso complex, 12 to 25 percent slopes. These strongly sloping to hilly soils are on mesas, alluvial fans, and sides of valleys. Elevation ranges from 5,000 to 6,500 feet. The Potts soil formed in alluvium derived from sandstone, shale, or basalt. The Ildefonso soil formed in very strongly calcareous, basaltic alluvium and small amounts of eolian material.

Effective rooting depth is about 60 inches. Surface runoff is medium, and the erosion hazard is moderate. Included with this soil in mapping are small areas of Morval and Lazear soils. The Morval soils are at the higher elevations. The Lazear soils are shallow and are on ridge crests and steep mountainsides. These areas make up 10 to 18 percent of the map unit. These soils are used mainly for limited grazing and wildlife habitat. The native vegetation on the Potts soil is mainly wheatgrass, needleandthread, and sagebrush. The native vegetation on the Ildefonso soil is mainly pinyon and Utah juniper and an understory of Indian ricegrass, wheatgrass, junegrass, serviceberry, bitterbrush, and sa- gebrush. When the understory vegetation deteriorates, grasses almost disappear and forbs and shrubs increase. Proper- ly managing grazing maintains and improves range con- dition on both soils. Seeding improves range in poor condition in less sloping areas of the Potts soil. Blue - bunch wheatgrass, western wheatgrass, and need- leandthread are suitable for seeding. Preparing the seedbed and drilling the seed are good practices. Con- trolling brush on the Potts soil improves range that is producing more shrubs than are normally found in the potential plant community. Properly managing the under - story vegetation on the Ildefonso soil maintains wood production and grazing. Selectively thinning pinyon and juniper improves grazing and provides firewood, posts, and Christmas trees. The Ildefonso soil is suited to production of pinyon and Utah juniper. It can produce 9 cords of wood per acre when trees more than 4.5 feet tall reach an average diameter (at one foot) of 5 inches. The low available water capacity affects survival of tree seedlings. 34 Mule deer, wild turkey, chukar, gray squirrel, cottontail rabbit, and some pheasant find habitat on these soils. The steep slopes limit community development. Struc- tures are needed to divert runoff to minimize gullying and erosion. This complex is in capability subclass Vle, nonirrigated. 59—Potts-Ildefonso complex, 25 to 45 percent slopes. These hilly to very steep soils are on alluvial fans and sides of valleys.

The native vegetation on the Ildefonso soil is mainly pinyon and Utah juniper and an understory of Indian ricegrass, wheatgrass, junegrass, serviceberry, bitterbrush, and sa- gebrush. When the understory vegetation deteriorates, grasses almost disappear and forbs and shrubs increase. Proper- ly managing grazing on the Potts soil maintains and improves the range condition. Properly managing the vegetation on the Ildefonso soil maintains wood produc- tion and ground cover. The value for grazing is low SOIL SURVEY because of steep slopes and the tree canopy. Firewood, posts, and Christmas trees can be harvested from the more gently sloping areas. The Ildefonso soil is suited to production of pinyon and Utah juniper. It can produce 9 cords of wood per acre when trees more than 4.5 feet tall reach an average diameter (at one foot) of 5 inches. The low available water capacity affects survival of tree seedlings. Steep slopes and the severe erosion affect harvesting. Mule deer, wild turkey, chukar, gray squirrel, cottontail rabbit, and some pheasant find habitat on these soils. Community development is limited by very steep slopes. This complex is in capability subclass Vile, nonirrigat- ed. 60—Rhone loam, 5 to 30 percent slopes. This deep, well drained, gently sloping to steep soil is on mountain- sides and ridges. Elevation ranges from 7,600 to 8,600 feet. This soil formed in residuum from sandstone and marlstone. The average annual precipitation is about 20 inches, the average annual air temperature is about 40 degrees F, and the average frost -free period is less than 75 days. Typically, the upper part of the surface layer is brown loam about 8 inches thick, and the lower part is brown sandy clay loam about 20 inches thick. The underlying material is brown extremely channery sandy clay loam about 24 inches thick. Sandstone is at a depth of 52 inches. Included with this soil in mapping are small areas of Parachute and Northwater soils. The moderately deep Parachute soils are on smooth ridge crests and west - and south -facing side slopes. The Northwater soils are on north -facing side slopes. These areas make up about 10 to 15 percent of the map unit. Permeability is moderate, and available water capacity is moderate. Effective rooting depth is 40 to 60 inches. Surface runoff is slow, and the erosion hazard is slight. This soil is used mainly for wildlife habitat and limited grazing. The native vegetation is mainly brome, needlegrass, and sagebrush. There are small areas of dwarfed aspen, but they are of little or no commercial value. When range condition deteriorates, forbs, shrubs, and Kentucky bluegrass increase. Properly managing grazing maintains and improves range condition. Seeding and removing brush improve range on less sloping areas if it is in poor condition. Intermediate wheatgrass, slender wheatgrass, and mountain or smooth brome are suitable for seeding. Preparing the seedbed and drilling the seed are good practices. Elk, mule deer, coyote, grouse, and rabbit find habitat on this soil. Use of this soil for community development or as a source of construction material is limited by steep slopes. 90 TABLE 1. --TEMPERATURE AND PRECIPITATION DATA* SOIL SURVEY Month Temperature* 1 Precipitation* Averagel Average daily 1 daily maximumlminimum Average daily 2 years in 10 will have -- i Maximum I Minimum temperature 1 temperature higher 1 lower than-- 1 than -- Average 1 number oflAverage growing 1 degree 1 days** 2 years in 10 will have -- Less than -- More than -- i Average number of Average days with snowfall 0.10 inch or more January---- February--- March April May June July August September i October i November i December' Year of 36.2 42.9 52.2 62.9 73.9 83.3 89.6 86.8 78.9 67.5 50.6 37.9 63.6 of 9.2 15.4 22.6 29.9 37.7 44.0 50.5 49.4 39.8 30.5 21.2 11.4 of 22.7 29.2 37.4 46.4 55.8 63.7 70.1 68.1 59.4 49.0 35.9 24.7 30.1 1 46.9 of i of 53 1 -18 61 -12 73 1 3 80 i 14 89 i 23 96 l 31 98 l 38 96 l 36 93 l 25 84 1 15 69 1 61 -13 98 1 -23 16 33 69 201 490 711 933 871 582 285 40 11 4,242 In 0.90 0.73 0.70 0.83 0.82 0.88 0.82 1.32 1.03 1.27 0.85 1.10 1 In 0.31 l 0.25 i i 0.28 1 i 0.50 0.19 i 0.21 0.27 0.55 0.28 0.40 0.45 0.43 8.61 In 1.36 1.11 1.04 1.11 1.31 1.41 1.25 1.93 1.62 1.96 1.17 1.57 13.62 3 2 3 3 3 2 3 4 3 3 3 4 36 In 13.5 8.5 4.6 1.8 .0 .0 .0 .0 .3 .8 5.9 14.5 49.9 *Recorded in the period 1951-74 at Rifle, CO. **A growing degree day is an index of the amount of heat available for plant growth.

B (EPA) - The indicated compound was found in the associated method blank as well as the laboratory sample. J7 Surrogate recovery limits cannot be evaluated; surrogates were diluted out 0 (ESC) Sample diluted due to matrix interferences that impaired the ability to make an accurate analytical determination. The detection limit is elevated in order to reflect the necessary dilution. T8 (ESC) - Additional method/sample information: Sample(s) received past/too close to holding time expiration. Qualifier Report Information ESC utilizes sample and result qualifiers as set forth by the EPA Contract Laboratory Program and as required by most certifying bodies including NELAC. In addition to the EPA qualifiers adopted by ESC, we have implemented ESC qualifiers to provide more information pertaining to our analytical results. Each qualifier is designated in the qualifier explanation as either EPA or ESC. Data qualifiers are intended to provide the ESC client with more detailed information concerning the potential bias of reported data. Because of the wide range of constituents and variety of matrices incorporated by most EPA methods,it is common for some compounds to fall outside of established ranges. These exceptions are evaluated and all reported data is valid and useable unless qualified as 'R' (Rejected). Definitions Accuracy - The relationship of the observed value of a known sample to the true value of a known sample. Represented by percent recovery and relevant to samples such as: control samples, matrix spike recoveries, surrogate recoveries, etc. Precision - The agreement between a set of samples or between duplicate samples. Relates to how close together the results are and is represented by Relative Percent Differrence. Surrogate - Organic compounds that are similar in chemical composition, extraction, and chromotography to analytes of interest. The surrogates are used to determine the probable response of the group of analytes that are chem- ically related to the surrogate compound. Surrogates are added to the sample and carried through all stages of preparation and analyses.

Qualifier Report Information ESC utilizes sample and result qualifiers as set forth by the EPA Contract Laboratory Program and as required by most certifying bodies including NELAC. In addition to the EPA qualifiers adopted by ESC, we have implemented ESC qualifiers to provide more information pertaining to our analytical results. Each qualifier is designated in the qualifier explanation as either EPA or ESC. Data qualifiers are intended to provide the ESC client with more detailed information concerning the potential bias of reported data. Because of the wide range of constituents and variety of matrices incorporated by most EPA methods,it is common for some compounds to fall outside of established ranges. These exceptions are evaluated and all reported data is valid and useable unless qualified as 'R' (Rejected). Definitions Accuracy - The relationship of the observed value of a known sample to the true value of a known sample. Represented by percent recovery and relevant to samples such as: control samples, matrix spike recoveries, surrogate recoveries, etc. Precision - The agreement between a set of samples or between duplicate samples. Relates to how close together the results are and is represented by Relative Percent Differrence. Surrogate - Organic compounds that are similar in chemical composition, extraction, and chromotography to analytes of interest. The surrogates are used to determine the probable response of the group of analytes that are chem- ically related to the surrogate compound. Surrogates are added to the sample and carried through all stages of preparation and analyses.

The quality control samples include a method blank, a laboratory control sample, and the matrix spike/matrix spike duplicate analysis. If a target parameter is outside the method limits, every sample that is effected is flagged with the appropriate qualifier in Appendix B of the analytic report. Method Blank - an aliquot of regent water carried through the entire analytic process. The method blank results indicate if any possible contamination exposure during the sample handling, digestion or extraction process, and analysis. Concentrations of target analytes above the reporting limit in the method blank are qualified with the "B" qualifier. Laboratory Control Sample - is a sample of known concentration that is carried through the digestion/extraction and analysis process. The percent recovery, expressed as a percentage of the theoretical concentration, has statistical control limits indicating that the analytic process is "in control". If a target analyte is outside the control limits for the laboratory control sample or any other control sample, the parameter is flagged with a "J4" qualifier for all effected samples. Matrix Spike and Matrix Spike Duplicate - is two aliquots of an environmental sample that is spiked with known concentrations of target analytes. The percent recovery of the target analytes also has statistical control limits. If any recoveries that are outside the method control limits, the sample that was selected for matrix spike/matrix spike duplicate analysis is flagged with either a "J5" or a "J6". The relative percent difference (%RPD) between the matrix spike and the matrix spike duplicate recoveries is all calculated. If the RPD is above the method limit, the effected samples are flagged with a "J3" qualifier. Page 10 of 10 EXHIBITS EnCana Oil and Gas (USA), Inc.

APPLICANT(S): EnCana Oil & Gas (USA), Inc. PROPERTY OWNER: Benzel Livestock Company (John Benzel) LOCATION: The subject property is located in the Hunter Mesa area, approximately 1 mile south of County Road 322 and 1 mile east of County Road 319 (W. Mamm Creek Road). SITE INFORMATION: 8 acres WATER: Will not be used SEWER: Will not be used ACCESS: Driveway easement off of County Road 319 EXISTING ZONING: A/R/RD (Agricultural / Residential / Rural Density) ADJACENT ZONING: A/R/RD L DESCRIPTION OF THE PROPOSAL: A. Summary of Request: The Applicant requests approval for the construction and operation of natural gas production water evaporation pits and associated holding tanks. B. Project Description: The Applicant operates natural gas wells in Garfield County. These wells produce a brackish water referred to as "produced water". According to the Applicant, a natural gas well generates produced water at a historical rate of averaging approximately 2.5 barrels per day. Produced water is alkaline and needs to be disposed of properly. The primary EnCana Oil & Gas (USA), Inc. Special Use Permit BOCC —1/6/03 Page 2 non -water component of the produced water is sodium chloride. Traces of other salts, such as magnesium chloride and sodium bicarbonate, are also present. The produced water contains an average of 10,000 parts per million total dissolved solids ("TDS"). This level of salinity is beyond potable but lower than that of seawater. Produced water also contains trace amounts of free and dissolved oil. Produced water is also generated during the drilling and completion of a natural gas well. It is necessary to truck several hundred barrels of water from a drill site after completion of a well. The Applicant (formerly known as Snyder Oil) has operated an evaporation pit facility near Rifle off of County Road 319 since 1996. Approval for this evaporation pit was granted by the Board pursuant to Resolution No. 96-21 (Exhibit J). The Applicant indicated that the capacity of this evaporation pit is no longer adequate. The pits proposed as part of this application will be constructed next to the Hunter Mesa Booster Station. The Applicant asserted that the location for the proposed Facility was selected due to a number of beneficial reasons. The significant reason is that the proposed location is central to EnCana existing operations in the area. According to the Applicant, the new Facility will be constructed differently than the existing Rifle evaporation pit facility. The Applicant indicated that the new Facility will be equipped with extra measures to prevent oil from reaching the evaporation pits. The off-load water tanks will be plumbed in series with internal weirs and at individual well(s) most the oil and/or natural gas will be separated from the produced water and contained. Water discharged from the off-load tanks will pass through a gas powered heater in which any oil that may carry over from the tanks will be separated and contained. The heater increases the water temperature thereby increasing the evaporation rate. The water is typically stored in 80 -barrel capacity tank on location and then intermittently hauled off site. The majority of the water that passes through the Facility will not be evaporated but will be purified and reused in the hydro -fracturing operations. Approximately three quarters of the production water will exit the heater system into a electronic water treatment system. The electronic water treatment system will lower the IDS to well below 3,000 ppm (parts per millions) and the treated water will be stored in a separate Low TDS pond. Water will be pulled from the Low TDS ponds, as needed, for hydro -fracturing. Produced water will be sprayed over the pond to increase the evaporation rate. A series of center -mounted sprinklers will distribute the water over the pond in droplets. The droplets will be small enough to maximize evaporation while not creating a mist. The Applicant indicated that the anticipated total rate of spraying is approximately 500 gallons per minute. The sprinkler lines will be charged by a 460 C.I. motor powering a Berkley 3/8 pump. The pump and EnCana Oil & Gas (USA), Inc. Special Use Permit BOCC — 1/6/03 Page 3 distribution lines will be situated within the lined area so that in the event of a leak the water will be contained. The Facility will utilize 3 sizes of above -ground steel holding tanks, a total of 9 tanks. The dimensions and functions of the holding tanks are as follows: Number of Tanks Tank Capacity (barrel = bbl) Diameter Height Function 3 400 bbl 12 ft 20 ft Will hold the production water off-loaded from the water trucks 5 300 bbl 12 ft 15 ft Will hold water or oil from the heater treater separator system 1 230 bbl 10 ft 15 ft Will capture overflow from the other tanks The Applicant noted that the hours of operation for the Facility will be as follows: 1. The evaporation system pump and sprayers will operate 7 days a week, 24 hours a day during the spring and summer months and will be purged and shut down for the fall and winter months. 2. The electronic water treatment system and heater treater will operate 365 days of the year, 7 days a week, 24 hours a day. 3. The majority of the water trucks will travel to and from the site between 8:00 am and 4:00 pm with some trips made outside of these hours as necessary. C. Site Description: The subject property is very level. The vegetation on the subject area is sparse sage brush. The Facility will be located immediately adjacent to an existing compressor site. The subject area contains a total of 8 acres which will be completely encompassed by a non -security 8 -foot field fence (wood posts with wire mesh panels). D. Zoning: The subject property is zoned A/R/RD (Agricultural / Residential /Rural Density). The type of use requested falls under the definition of "Processing" which is a Special Use in the A/R/RD zone district. "Processing" is a subcategory of "Industrial Operations Classification", therefore it is subject to the standard outlined in Section 5.03.07 of the Garfield County Zoning Resolution. EnCana Oil & Gas (USA), Inc. Special Use Permit BOCC —1/6/03 Page 4 E. Relationship to the Comprehensive Plan: The subject property is designated on the "Proposed Land Use Districts, Study Area 2 & 3" map in the Garfield County Comprehensive Plan of 2000, as "Outlying Residential." Outlying Residential is consistent with the underlying zoning, which in the case of A / R / RD is a minimum lot area of 2 acres. The subject property is located outside of the 2 mile sphere of influence for both the City of Rifle and the Town of Silt. F. Adjacent Land Uses: The area surrounding the proposal is pre -dominantly range land with similar, oil and gas, type land uses. The closest residence is over a mile southeast of the subject site. G. Road/Access: The primary access to the subject area is via a driveway easement off of County Road 319. However, the site is accessible from County Road 322. No modifications to the road system is required as part of this approval. H. Applicability: Pursuant to Section 9.03.04 of the Zoning Resolution, an application for a Special Use Permit shall be approved or denied by the Board of County Commissioners after holding a public hearing thereon in conformance with all provisions of the Zoning Resolution. II. REVIEW AGENCY AND OTHER COMMENTS: Comments were received from the following agencies are have been integrated throughout this memorandum as applicable. 1. Colorado Division of Wildlife: Exhibit I 2. Rifle Fire Protection District: No comment. 3. Bureau of Land Management: No comment. 4. Garfield County Road and Bridge Department: Exhibit G 5. Garfield County Vegetation Management: Exhibit H III. REVIEW CRITERIA. FOR SPECIAL USE PERMITS (SECTION 5:03) Pursuant to Section 5.03, as listed under the Zone District Regulations, special uses shall conform to all requirements listed thereunder and elsewhere in the Zoning Resolution, as well as the following standards: 1. Utilities adequate to provide water and sanitation service based on accepted engineering standards and approved by the Board of County Commissioners shall either be in place or shall be constructed in conjunction with the proposed use. EnCana Oil & Gas (USA), Inc. Special Use Permit BOCC —1/6/03 Page 5 Response: The Applicant indicated that there will be no use of either groundwater or natural surface water for the Facility. There will also be no sewage generated on the site. During construction, portable sanitary facilities shall be installed. Construction of the Facility is expected to take approximately 10 weeks. 2. Street improvements adequate to accommodate traffic volume generated by the proposed use and to provide safe, convenient access to the use shall either be in place or shall be constructed in conjunction with the proposed use. Response: The Applicant asserted that the majority of the water trucks will travel to and from the site between the hours of 8:00 am to 4:00 pm. Some trips may be made outside of these hours, as necessary. The Facility is expected to generate approximately a total of 20 to 25 water - tanker truck trips per day. The majority of the trips will be on existing private roads that already service natural gas operations on Hunter Mesa. The Applicant asserted that heavy trucks already frequently travel the roads in the Hunter Mesa area, therefore, the new facility is not expected to require improvements to the existing roads. Presently, the Applicant hauls produced water to their evaporation pit on CR 319 just south of Rifle, as well as to the Black Mountain disposal facility in Mesa County. The new Facility will reduce the number of trips to the present evaporation facilities, thereby keeping the majority of the truck traffic further from the Town of Rifle. Jake Mall, Garfield County Road and Bridge Department, provided the following comments (seen in more detailed in Exhibit G): A. The entrance to the proposed evaporation pits is an existing driveway that was built to County standards for large truck traffic. A new driveway will not be needed to accommodate the new use. B. The increase in traffic will not be a problem, as the road has been upgraded to a heavy traffic haul road. EnCana Oil and Gas USA contributed a large amount of money both for improvements and maintenance of CR 319. The Road and Bridge Department has no reason to believe that the Applicant will not continue to provide support for the continued maintenance of CR 319. C. The Road and Bridge Department's biggest concern is that the trucks abide by the posted speed limit on CR 319 and practice safe driving methods. The posted speed limit on CR 319 is 35 MPH. EnCana Oil and Gas USA has a company policy that their employees and subcontractors abide by a company speed limit of 30 mph to increase safety on the roads that they use for their business. EnCana Oil & Gas (USA), Inc. Special Use Permit BOCC, — 1/6/03 Page 6 3. Design of the proposed use is organized to minimize impact on andfi•omn adjacent uses of land through installation of screen fences or landscape materials on the periphery of the lot and by location of intensively utilized areas, access points, lighting and signs in such a manner as to protect established neighborhood character. Response: No outdoor storage buildings are associated with the evaporation pits. The property boundary will be surrounded by 8 -foot tall, non -security field fence (wood posts with wire mesh panels). The fencing will contain two steel access gates and cattle guards will be installed at both gates. The Applicant noted that the gates will remain open during daylight hours and will be secured overnight. The Applicant asserted that surrounding uses are such that a visible barrier fence should not be necessary. In Exhibit M of the application, the Landscaping Plan states that "due to the remote location landscaping efforts will be directed at erosion control as opposed to visual impacts. Any areas disturbed by construction and not covered by liner or equipment will be resurfaced with sand and gravel." The Applicant indicated that the tanks associated with the pits will be painted in a beige color to match the surrounding terrain. Signage will be visible and include the company name and address, as well as 24-hour toll-free emergency phone number. .Pursuant to Section 5.03.10, uses listed as Special Uses shall be permitted only: 1. Based on compliance with all requirements listed herein, and; 2. Approval by the County Commissioner, which Board may impose additional restrictions on the lot area, floor area, coverage, setback and height of proposed uses or required additional off-street parking, screening fences and landscaping, or any other restriction or provision it deems necessary to protect the health, safety and welfare of the population and uses of the neighborhood or zone district as a condition of granting the special use. Response: Staff sees no reason for the Board to impose any special conditions. Section 5.03.07 (Industrial Operations]: Pursuant to Section 5.03,07 of the Zoning Resolution, a permit for Industrial Operations requires the submittal of an impact statement on the proposed use describing its location, scope, design and construction schedule, including an explanation of its operational characteristics. The impact statement is required to address the following: EnCana Oil & Gas (USA), Inc. Special Use Permit BOCC -1/6/03 Page 7 (A) Existing lawful use of water through depletion or pollution of surface run-off, streamflow or ground water. Response: The Applicant asserted that the location of the proposed Facility is underlain by gravels and alluviums derived mainly from sandstone, shale, or basalt. The predominate soil type in the site area is very clayey loam. The Applicant asserted that the Facility has been designed to protect the groundwater resources, The pits will be lined with impermeable HDPE (High Density Polyethylene) and if groundwater is encountered during construction, monitoring wells will be installed and sampled regularly. Exhibit K of the application outlines the liner installation procedures. (B) Impacts on adjacent land, from the generation of vapor, dust, smoke, noise, glare or vibration, or other emanations. Response: The Applicant noted that noise will emanate from the aeration pump and sprayers. The Applicant asserted that the sound level of noise emanating from the Facility will not exceed the 75 decibel maximum set forth in the Colorado State Statute 25-12-103. Seventy five (75) db(A) is for the `Industrial' zone. Pursuant to Colorado State Statues, "sound levels of noise radiating from a property lines at a distance of twenty-five feet or more therefrom in excess of the db(A) established for the following time periods and zones shall constitute prima facie evidence that such noise is a public nuisance:" Zone 7:00 am to next 7:00 pm 7:00 pm to next 7:00 am Residential 55 db(A) 50 db(A) Commercial 60 db(A) 55 db(A) LightIndus trial 70 db(A) 64 db(A) Industrial 80 db(A) 75 db(A) Staff feels that the County shall enforce appropriate noise regulations which may require the Applicant to meet the 55 db(A) established for the `Residential" zone. The Applicant indicated that during the evaporation process and estimated 2 percent of spray is lost to driftage. The Applicant noted that the saline nature of the produced water can potentially impact vegetation on surrounding lands. The driftage also has a noticeable odor. The Applicant asserted that as along as the driftage is contained, the odor is also contained. A berm, approximately 20 feet tall and 60 feet wide at its base, on the downwind side (south and east) of the pits, is proposed to be constructed in order to mitigate driftage from the spray and noise. EnCana Oil & Gas (USA), Inc. Special Use Permit BOCC —1/6/03 Page 8 The Applicant asserted that given the remote location of the new Facility, noise or odor will not be a nuisance. However, if in the unlikely event nuisance noise or odors are emanated by the Facility, extra measures will be taken to control them. This shall also pertain to dust, smoke, glare and vibration shall any of these be created by the Facility. (C) Impacts on wildlife and domestic animals through the creation of hazardous attractions, alteration of existing native vegetation, blockade of migration routes, use patterns or other disruptions. Response: The Applicant indicated that the type of facility is by nature incompatible with continued wildlife access, therefore, wildlife -proof fencing will be installed. The Applicant noted that an oil separating system will be employed to prevent oil from reaching the holding pond in order to eliminate potential impacts to waterfowl. The Applicant asserted that attraction of waterfowl to the holding pond is not expected, but a deterrence system will be installed if waterfowl usage does occur. Brett Ackerman, of the Colorado Division of Wildlife, noted that the property is classified as severe winter range for elk and mule deer, winter concentration for elk, and overall range for black bear and mountain lion. Mr. Ackerman has offered the following comments (seen in more detail in Exhibit I): 1. Water attracts wildlife, particularly in areas such as the proposed site where water is relatively scarce. Because of the heated nature of the water, the pits will likely remain open during the colder months which will possibly attract waterfowl and small mammals. In addition to the proposed 8 -foot high perimeter big game fence, a 2 to 3 -foot high mesh small game fence immediately surrounding the pits and buried 6 to 8 inches in the ground would protect animals that are able to penetrate the outer fence. 2. Impermeable liners make it difficult, if not impossible, for any animals that enter the pits to escape. Escape ramps are essential in facilitating the escape of any wildlife species that manage to reach the water. A simple structure should be constructed in each body of water that would allow animals to escape the ponds should they become trapped. 3. Separation system to prevent oil from reaching the ponds is a positive component to the plan to protect any animals that do reach the pits. Pits should be monitored for oil. If any oil reaches the ponds measures should be taken to immediately remove it. Furthermore, the heated and saline nature of the pits can be detrimental and fatal to waterfowl and other migratory birds. Pond netting over all the pits on the facility would help to prevent migratory birds from resting and/or foraging on the ponds, particularly during the winter months. EnCana Oil & Gas (USA), Inc. Special Use Permit BOCC —1/6/03 Page 9 4. The death of any migratory birds caused by the proposed facility is a violation of state and federal law. Any deaths of migratory birds or other wildlife alb ibutable to this facility must be immediately reported to the CDOW and US Fish and Wildlife Services. 5. Studies have found that sodium chloride has behavioral and toxic impacts on animals and vegetation. Salts, expected to be by-products of the Facility, are highly soluble and will follow any water flow. Accordingly, streams, small lake ecosystems and groundwater are particularly vulnerable to salt runoff. Steps should be taken to ensure that any run-off from the site be contained on site. (D) Affirmatively show the impacts of truck and automobile raffle to and from such uses and their impacts to areas in the County. Response: Impacts of truck and automobile traffic to areas in the County have been discussed throughout this memorandum. (E) That sufficient distances shall separate such use from abutting property which might otherwise be damaged by operations of the proposed use(s). Response: The closest residence to the Facility is over 1 mile southeast of the site. Similar oil and gas type land uses surround the proposed Facility. Precaution, such as noise and odor, proposed by the Applicant are discussed throughout this memorandum. (F) Mitigation measures proposed for all of the foregoing impacts identified and for the standards identified in Section 5.03.08 of this Resolution Response: Mitigation measures for all of the foregoing impacts identified have been addressed throughout this memorandum. Mitigation measures for the standards identified in Section 5.03.08 [Industrial Performance Standards] of the Garfield County Zoning Resolution are addressed beginning on Page 10 of this memorandum. Special Use Permits may be granted for those uses with provisions that provide adequate mitigation for the following: (A) A plan for site rehabilitation must be approved by the County Commissioners before a permit for conditional or special use will be issued; Response: The estimated life of the facility is between 10 and 20 years. The Applicant has provided a Reclamation Plan in Exhibit M of the application. The reclamation of the site will consist of the following steps, but shall not be limited to: EnCana Oil & Gas (USA), Inc. Special Use Permit BOCC —1/6/03 Page 10 1. Removal of all surface equipment and liner materials. 2. Restoration of grade to approximate original conditions. 3. Replacing stockpiled topsoil. 4. Complying with all prevailing COGCC and Garfield County regulations governing final reclamation. Steve Anthony, Director of Vegetation Management, provided comments with regard to the proposed Reclamation Plan submitted with the application. These comments are summarized below and can be seen in more detail in Exhibit H. 1. Noxious Weeds: a. Inventory and map noxious weeds on site. b. Provide a weed management plan. 2. Revegetation: a. Revegetation Plan shall include plant material list, planting schedule, and a revegetation bond or security (in the amount of $13,920.00 for 8 acres of disturbance). (B) The County Commissioners may require security before a permit for special or conditional use is issued, if required. The applicant shall furnish evidence of a bank commitment of credit, bond, certified check or other security deemed acceptable by the County Commissioners in the amount calculated by the County Commissioners to secure the execution of the site rehabilitation plan in workmanlike manner and in accordance with the specifications and construction schedule established or approved by the County Commissioners. Such commitments, bonds or check shall be payable to and held by the County Commissioners; Response: The Applicant shall comply with this provisions if deemed necessary by the Board of County Commissioners. (C) Impacts set forth in the impact statement and compliance with the standards contained in Section 5.03.08 of this Resolution.

It is important to ensure that any proposed disturbance is backed up by a commitment to revegetation and follow-up weed management. My recommendation is to request a more detailed vegetation plan with particular emphasis on the revegetation component. My comments are as follows: 1. Noxious Weeds D. Inventory and mapping -I suggest that the applicant map and inventory the proposed project area for any listed Garfield County Noxious Weeds (attached). ➢ Weed Management -The applicant shall provide a weed management plan that is specific to the inventoried noxious weeds. 2. Revegetation The applicant has quantified the disturbed area as eight acres. The applicant needs to provide a Revegetation Plan that includes: ➢ Plant material list (be specific, scientific and common names required). ➢ Planting schedule (to include timing and methods). ➢ A revegetation bond or security. This may be: D. A check/cash deposit with the County Treasurer. (This is preferred by the County, a deposit agreement to be drafted by the County Attorney is necessary). ➢ A letter of credit from an in-state financial institution. ➢ A bond or surety from a bonding or insurance company. (The bond must refer to the Reclamation Plan and the special use permit number). The Vegetation Management Department recommends that a revegetation security in the amount of $1740/acre (4 cents per square foot) be held until vegetation has been successfully reestablished. This figure has been calculated to anticipate market costs for reclamation in 10-20 years when the site is closed and recontoured for reclamation. This amount totals $13,920.00 for eight acres of disturbance. The security shall be held by Garfield County until vegetation has been successfully reestablished according to Sections 4.07 and 4.08 of the Garfield County Weed Management Plan. The Board of County Commissioners will designate a member of their staff to evaluate the reclamation prior to the release of the security. Please feel free to contact me at 625-3969.

I have reviewed the application along with its respective attachments and references, and have evaluated the operation's anticipated effects on wildlife. The proposed site is privately owned rangeland, and is classified as severe winter range for elk and mule deer, and overall range for black bear and mountain lion. In addition, it is listed as a winter concentration area for elk. According to Colorado System for Conservation Planning (SCoP) mapping practices, the following federal threatened and endangered species have suitable habitat, but have not necessarily been observed in the area of interest. • American peregrine falcon • Bald eagle • Mexican spotted owl • Southwestern willow flycatcher • Whooping crane The following state threatened and endangered species have suitable habitat, but have not necessarily been observed in the area of interest. • American peregrine falcon • Bald eagle • Greater sandhi]] crane • Kit fox • Mexican spotted owl • Western burrowing owl • Whooping crane As the application states, this type of facility is, by nature, imcompatible with continued wildlife access. Therefore, measures must be taken in order to ensure' that the facility does not create a hazard to surrounding wildlife. DEPARTMENT OF NATURAL RESOURCES, Greg E.

Ackerman (970) 625-2876 p.03 Water attracts wildlife, particularly in areas such as the proposed site where water is relatively scarce. Because of the heated nature of the water, the ponds will likely remain open during the colder months and one would expect waterfowl and small mammals to be attracted to them. In addition to the proposed eight -foot -high perimeter big game fence, a two to three -foot -high mesh small game fence immediately surrounding the ponds and buried six to eight inches in the ground would protect animals that are able to penetrate the outer fence. - Impermeable pond liners make it difficult, if not impossible, for any animals that enter the pond to escape. Escape ramps are essential in facilitating the escape of any wildlife species that manage to reach the water. A simple structure should be constructed in each body of water that would allow animals to escape the ponds should they become trapped. The applicant's proposed separation system to prevent oil from reaching the ponds is a positive component to a plan to protect any animals that do reach the ponds. In addition, ponds should be monitored for oil, and if oil reaches the ponds measures should be taken to immediately remove it. Furthermore, the heated and saline nature of the . proposed ponds can be detrimental and fatal to waterfowl and other migratory birds. Pond netting over all ponds on the facility would help to prevent migratory birds from resting and/or foraging on the ponds, particularly during the winter months. The death of any migratory bird caused by the proposed facility is a violation of state and federal law. Any deaths of migratory birds or other wildlife attributable to this facility must be immediately reported to the Colorado Division of Wildlife and the United States Fish and Wildlife Service. Studies have found that sodium chloride has behavioral and toxic impacts on animals and vegetation. Salts expected to be byproducts of this facility are highly soluble and will follow any water flow. Accordingly, streams, small lake ecosystems and groundwater are particularly vulnerable to salt runoff Steps should be taken to ensure that any runoff from the site be contained on site. Measures should be taken to monitor soil and groundwater in order to avoid any degradation in water quality and soil type and structure over the life of the project. Returning the site to slope with fill and seeding should not be considered complete reclamation if the soil and surrounding area has degraded due to activities performed on the site. In addition, operation and reclamation of the site should include a comprehensive weed control plan in order to prevent establishment and infestation of noxious weeds. Thank you for the opportunity to comment on this important land use issue in Garfield County. Please feel free to contact me to regarding this or any other wildlife matter. Sincerely, Brat A.

I was advised to leave condition #14 as approved by the Board at a public hearing. Any changes to the recommended conditions, as noted below, would require a new public hearing. Unless I hear from you differently, the Resolution will remain on the BOCC agenda, as drafted, for the Chairman's signature Monday, January 20tH Tamara Original Message From: Craig Meis [mailto:craigmeis@cordcomp.com] Sent: Tuesday, January 14, 2003 11:59 AM To: Tamara Pregl Cc: john.Ieacock@encana.com; Chris Williams; Bob Chesson; Bob Powers; Dion Plsek; Dave Grisso Subject: RE: EnCana Resolution of approval Importance: High Tamara A concern has been raised over the wording of condition 14 of the draft Resolution that I hoped to clarify on behalf of Encana and revise prior to the Resolution being finalized on 1/20 to avoid any potential future conflicts. Our concern is specifically with the stated hazardous or toxic analysis and data submittal on an annual basis of the water contained within the evaporation pits. All water treated at this facility is characterized as an E&P waste, as defined in 34-60-103(4.5) C.R.S., which is specifically under the jurisdictional and regulatory authority of the COGCC for the State of Colorado. Being granted the State authority, the COGCC has established analytical testing requirements associated with the permitting and operation of a Centralized E&P Waste Management Facility which this facility would be classified. I would suggest to avoid any potential conflict regarding the regulatory jurisdiction of a waste considered to be E&P exempt under the federal Resource Conservation and Recovery Act (RCRA) that condition 14 simply state that analytical testing protocols and procedures will be adhered to as written specifically under Section 908 of the COGCC Rules and Regulations. I hope this e-mail helps clarify the rational for our concern however should further discussion be necessary please don't hesitate to contact myself at your earliest convenience. I apologize for any confusion and not clarifying this issue in greater detail at the hearing however we were unaware of the specific condition language until we received the draft Resolution. I would be more than happy to clarify this issue with any or all of the Commissioners if necessary. Our intent is not to avoid the requirements as written under condition 14 but simply to restate the condition so that it is consistent with the applicable regulatory body and existing rules. Again, please do not hesitate to contact myself with any questions or concerns. Thanks Craig J.
