PHASE 3 PIPELINE EnCana Oil & Gas (USA) Inc. REQUEST TO AMEND East Dry Hollow Loop Phase 1 Pipeline I. APPLICATION SUBMITTAL REQUIREMENTS As a minimum, specifically respond to all the following items below and attach any additional information to be submitted with this application: Development Plan Submissions: The applicant shall submit eight copies of the proposed development plan with the completed application form to the Planning Director. The following information must be submitted with a development plan application: (1) Vicinity map indicating the section, township, and range of the site, and its relation to surrounding public roads and municipal boundaries. Project maps are provided in Attachment 1. (2) Project Overview: a description of the project including the length of the pipeline, diameter of the pipeline, pipeline commodity, and the general description of the pipeline route. EnCana Oil & Gas (USA) Inc. (EnCana) is in the process of installing a 20 -inch diameter buried steel, low pressure gathering pipeline in the Mamm Creek field, per approval of the East Dry Hollow Loop Phase 1 (Phase 1) Pipeline Administrative Permit; whereby Phase 1 construction is nearing completion at the P4E. The proposed footage to extend pipeline construction east of the P3 is approximately 8,296 feet in length. The pipeline and related above -ground facilities will be located in Garfield County, Colorado. Reference Attachment 1-Topo D detailing Phase 1 route as well as the proposed amended route. To recap Phase 1 and the intent of the entire line, the 20 -inch pipeline is designed to a Maximum Allowable Operating Pressure (MAOP) of 435 psig (30% of SMYS) ANSI B31.8 with a Location 2 (0.6) safety design factor. The pipeline will be constructed using X-52 grade pipe, 0.281 inch wall thickness, and ANSI 300 rated flanges. The system will be pressure protected with a Pressure Safety Valve (PSV) to prevent over -pressuring. The pipeline will require above- ground appurtenances (block valves, pig launchers and receivers) at both ends of the pipeline. Additional above ground appurtenances will be required to connect existing gathering lines to the new 20 -inch loop line. A PSV will be installed at the Hunter Mesa Compressor Station. (3) Ownership A. For individual right-of-way, a diagram showing adjacent properties and the approximate location of buildings and their uses within a distance of 350 feet of any proposed structure, facility, or area to be disturbed. This may be drawn at a smaller scale than the site plan. B. For an area plan, the map will show the property boundaries and ownership information for all private and public property include in the development area. DEVELOPMENT PLAN APPLICATION 1 03/01/2008 TOMBSTONE PHASE 3 PIPELINE There are two houses within 350 feet of the proposed project. Reference the Garfield County Assessors Map provided in Attachment 1. (4) Evidence of surface owner notification and of surface agreements where the surface owner is not a party to the mineral lease. The pipeline crosses EnCana and three landowners. All landowners within 200 feet of the project are affected surface owners. Copies of Right -of -Way Easements for each surface landowner were submitted with the original Request to Amend Letter of July 31, 2008, but can be referenced in Attachment 4 (5) Need for Proposed Action: a statement of the reason for the pipeline. The basis to amend Phase 1 was outlined in the previous Request to Amend letter stating that landowner negotiations were suspended in a particular section of our proposed Phase 2; therefore it was at the recommendation of our Midstream Gathering team to request immediate approval to extend our pipeline construction. As mentioned above, Phase 1 is nearing completion and it would be a great cost savings to keep moving forward with pipeline construction, as our equipment and personnel are staged and readily available near this site and we are hopeful to avoid demobilization of our current resources. The Application Narrative Tab contains the July 31, 2008 Letter to Amend, stating the need for amendment.

(10) Sensltva Areae Survey: List the types and areas of rnncern along the pipeline right-of-way, such as: sensitive plant populations, cultural, archeological, paleontological resources and wetlands identified during pre -construction environmental surveys, if applicable. A Wildlife Impact and Sensitive Areas Report was previously prepared by WestWater Engineering, Inc. (WestWater) for the existing East Dry Hollow Loop Phase I pipeline in March 2008. This current report is an Addendum to the March 2008 report and pertains to the additional proposed pipeline section. Descriptions of background information, landscape, setting, wildlife and sensitive species, as well as mitigation measures suggested to off -set potential impacts, are presented in the March 2008 report and apply to the pipeline extension unless otherwise noted. The Sensitive Resource Reports r__ the __ujcct are provided in Attachment J . Biological surveys were completed August 2008. The following wildlife impact assessments were identified: • possible loss of winter range to a small number of mule deer and elk that utilize the site. • possible loss of foraging and nesting vegetation/habitat to a small number of bird species. • possible disturbance to a raptor nest west of Dry Hollow Creek, depending on the time period of construction. Also completed were surveys for federally listed threatened and endangered plants and BLM sensitive species plants along the project right-of-way. No sensitive plant species were observed along the right-of-way. No wetlands were identified during construction of EnCana's existing pipelines along the projected corridor. The pipeline project will be constructed within an existing disturbance and will not impact any known wetlands. (11) Land Grant/Permits/Authorizations and Stipulations: attach a copy of any land grants, permits, and authorizations including stipulations. The Garfield County Utility Installation Permit is provided in Attachment 2. A copy of the Stormwater Discharge Permit is provided in Attachment 3. (12) Revegetation Plan: a. A plant material list. Be specific, scientific and common names are required. Include application rate in terms of pure live seed (PLS) per acre/. 4 DEVELOPMENT PLAN APPLICATION 03/01/2008 TOMBSTONE PHASE 3 PIPELINE b. A planting schedule that includes timing, methods, and mulching. c. A revegetation security. A security may be required if, in the determination of the County Vegetation Management, the proposed project has: (i) A potential to facilitate the spread of noxious weeds. (ii) A potential to impact watershed areas. (iii) A potential for visual impacts from public viewing corridors. (iv) Steep slopes (15% or greater) or unstable areas. (v) Disturbs large areas (Half an acre or greater) d. The revegetation security will be in an amount to be determined by the County Vegetation Management that will be site-specific and based on the amount of disturbance. The security shall be held by Garfield County until vegetation has been successfully reestablished, or for a period of time approved by the County Vegetation Management in any specific land use action, according to the Reclamation & Revegetation Standards Section in the Garfield County Weed Management Plan. The County Vegetation Management will evaluate the reclamation and revegetation prior to the release of the security. An Integrated Vegetation and Noxious Weed Management Plan was previously prepared by WestWater for the existing East Dry Hollow Loop Phase I pipeline in March 2008. This current report is an Addendum to the March 2008 report and pertains to the additional proposed pipeline section. This Addendum to the March 2008 report describes updated resource features and observations documented during a recent field survey of the additional pipeline extension. The report of March 2008, Section 4.1, discusses recommended seed mixes and reclamation measures that are applicable to the new pipeline extension. Based on the soil types, terrain, and the presence of noxious weeds in the pipeline ROW, successful reclamation is most likely if a seed mix of grasses is used. Two seed mixes are recommended for the East Dry Hollow Loop Phase 1 project based on the soil type and available moisture; one for the drier juniper/sagebrush sites and one for the meadow/riparian sites with more moisture. Recommended Seed Mix For Arid Sites - East Dry Hollow Loop Phase 1 Pipeline Addendum Common Name Variety Application Rate lbs PLS/acre Plant the Following (10% Total) Indian Ricegrass Nezpar, Paloma, Rimrock 1.9 And Both of the Following (15% each, 30% Total) Galleta Viva 2.5 Bluebunch Wheatgrass Secar 2.8 And One of the Following (20% Total) Thickspike Wheatgrass Critana 3.4 Slender wheatgrass San Luis 3.3 And Two of the Following (40% Total) Muttongrass 0.6 Sandberg Bluegrass 0.6 Bottlebrush Squirreltail 2.7 DEVELOPMENT PLAN APPLICATION 03/01/2008 5 TOMBSTONE PHASE 3 PIPELINE Total 17.8 lbs PLS/acre Recommended Seed Mix For Meadow and Riparian Sites — East Dry Hollow Loop Phase 1 Pipeline Common Name Variety Application Rate lbs PLS/acre And Both of the Following (20% each, 40% Total) Mountain Brome Garnet 5.8 Slender Wheatgrass San Luis 3.3 And One of the Following (20% each, 60% Total) Letterman Neeidegrass 3.5 Blue Wildrye Arlington 4.8 Thickspike Wheatgrass Critana 3.4 Idaho Fescue Joseph 1.2 Wheeler Bluegrass 0.6 Total 22.6 lbs PLS/acre For best results and success, the recommended grass mixture reseeding should be done in late autumn_ The reseeding rate should he doubled for broadcast application, Preferred seeding method is multiple seed bin rangeland drill with no soil preparation other than simple grading to slope and imprinting and waterbars where applicable. Alternative seeding methods include but are not limited to: • harrow with just enough soil moisture to create a rough surface, broadcast seed and re- harrow, preferably at a 90 degree angle to the first harrow; • hydro -seeding (most economical in terms of seed cost); and • hand raking and broadcast followed by re -raking at a 90 degree angle to the first raking. These are not the only means of replanting the site. However, these methods have been observed to be effective in similar landscapes. EnCana increased the original Revegetation Bond # 105073441 from $74,150.00 to $102,725.00 or $2,500 per acre of disturbance for the amended portion and as rider was issued to increase the bond. A copy of the permit bond rider is provided in Attachment 8 and the original will be forward to Garfield County, Board of County Commissioners upon receipt. (13) A weed management plan for all Garfield County listed noxious weeds and State of Colorado listed noxious weeds that are targeted by the Commissioner of Agriculture for statewide eradication. The August 2008 "Integrated Vegetation and Noxious Weed Management Plan" also identifies weeds found during the additional surveys. Most weed populations were observed along the alignment for the pipeline extension, primarily within previously disturbed areas. Noxious weeds observed included chicory, common burdock, musk thistle, Russian knapweed, and salt cedar tamarisk. The Integrated Vegetation and Noxious Weed Management Plan is provided in Attachment 5. 6 DEVELOPMENT PLAN APPLICATION 03/01/2008 TOMBSTONE PHASE 3 PIPELINE (14) Emergency Response Plan: include a fire protection and hazardous material spills plan, which specifies planned actions for possible emergency events, a listing of persons to be notified of all emergency events, a listing of person to be notified of an emergency event, proposed signage, and provisions for access by emergency response teams. The emergency plan must be acceptable to the appropriate fire district or the County Sheriff, as appropriate. The plan shall include a provision for the operator to reimburse the appropriate emergency service provider for costs incurred in connection with emergency response for the operator's activities at the site.

(EnCana) / East Dry Hollow Loop Phase 1 Pipeline — Request to Amend Dear Fred: This letter is In reference to our conversation of July 25, 2008, whereby I explained EnCana's need to extend pipeline construction on our East Dry Hollow Loop Phase 1 Pipeline, which is currently in progress. In the planning stages of East Dry Hollow Loop Phase 2, we came up against survey delays due to outstanding landowner negotiations on part of this proposed trunk line. Pipeline construction for Phase 1, complete to the P4E, should be in approximately two weeks. Therefore, it is at the recommendation of our Midstream Gathering team to request immediate approval to move forward with construction, while equipment and personnel are readily available at this site. Construction will last approximately five weeks. As requested, I am providing project maps from Phase 1 (Topo D and alignment sheets), as well as, amended Topo D and alignment sheets referencing proposed construction to the east from the P4E to just east of the P3, setting a launcher and tieing into our existing 12 -inch pipeline on EnCana's property. Also provided is the approved Garfield County Utility Permit allowing a road bore of County Road 331 and the Right -of -Way Easements for landowners Cherokee Mountain Estates, L.L.C. and Shirley A. Arbaney, Rick Arbaney, Courtney Arbaney and Tiffany K. Bevan. Please note, that an increase to the Revegetation Bond for approximately 11.43 acres will be submitted. When said Permit Bond is executed and received, I will forward you a copy. I look forward to your response and approval to extend pipeline construction of the East Dry Hollow Loop Phase I.

(Cordilleran) on behalf of EnCana Oil and Gas (USA), Inc. (EnCana), recently inventoried a pipeline route crossing West Divide Creek and several intermittent drainages. The route extends across private land, and the United States Army Corps of Engineers (USACoE) jurisdictional water crossing of West Divide Creek is on property owned by Miller Land and Cattle. This informational packet is being retained to comply with the Army Corps of Engineers Nationwide 404 permit requirements. Permitting for the crossings is being conducted under Nationwide 12 standards with optional courtesy notification of the USACoE. The work should be done in accordance with Colorado Regional Conditions. The West Divide Creek crossing, 7S -92W-1-2, will be constructed by directional boring. EnCana also intends to construct the other drainage crossings noted in the attached spreadsheet in accordance with USACoE regulations and best management practices. This includes an additional intermittent drainage crossing located on the Eubanks family's property that was inaccessible during the time of the survey, but was identified on the topographical map. Attachments with this letter include: a location map, data spreadsheet, and photographic log. Please do not hesitate to contact me at the above referenced phone number or at mikebrygger@a cordcomp.com if you have any questions or concerns. Thank you for your attention to this matter.

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 \\encana.com\dnvshared\South Rockies\Operations_South Piceance\Gathering Trunk Pipelines-Projects\Mamm Creek\STORMWATERWamm Creek SWMP (East Dry 1-1 Revised February 2008 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 1.2 SWMP Administrator The SWMP Administrator is responsible for the process of developing, implementing, maintaining, and revising this SWMP as well as serving as the comprehensive point of contact for all aspects of the facility's SWMP.

Activities at the Permit Coverage Area will likely involve the construction of: Colorado River within portions or all of 113 • Well pads • Access roads • Pipelines • Compressor stations • Water Treatment Facility • Fresh Water Storage Pond • Evaporation Facility 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: \\encana.comWnvshared\South_Rockies\Operations_South Piceance\Gathering Trunk Pipelines -Projects \Mamm Creek \STORMWATER\Mamm Creek SWMP (East Ory 2-1 Revised February 2008 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, 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. \\encana.com\dnvshared\South_Rockies\Operations South Piceance\Gathering Trunk Pipelines-Projects\Mamm Creek\STORMWATERWamm Creek SWMP (East Dry 2-2 Revised February 2008 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. 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 \\encana.mm\dnvshared\South_Rockies\Operations South Piceance\Gathering Trunk Pipelines-Projects\Mamm Creek \STORMWATERVdamm Creek SWMP (East Dry 2-3 Revised February 2008 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 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 \\encana.mm\dnvshared\South_RoUdes\Operations South Piceance\Gathering Trunk Pipelines-ProJects\Mamm Creek\STORMWATERNMamm Creek SWMP (East Dry 2-4 Revised February 2008 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: 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 \lencana.comldnvshared\South Rockies\Operations South Piceance\Gathering Trunk Pipelines -Projects Mamm Creek\STORMWATER\Mamm Creek SWMP (East Dry 2-5 Revised Febniary 2008 mix will be applied. This may occur after termination of this permit and under the coverage of a new construction permit. 2.2 Area Estimates The Permit Coverage Area encompasses portions or all of 113 sections of surface land (approximately 72,273 acres) in Township 6, 7, and 8 South, Range 92, 93, and 94 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, alluvial terraces, steep slopes, mountainsides, intermittent drainage swells, and valley bottoms. The Mamm Creek Unit is located south of the Colorado River, within the southern portion of the Piceance Basin. The Piceance Basin is a broad, asymmetric, southeast -northwest trending structural basin that contains sedimentary rocks up to 20,000 feet thick and lies between the White River uplift to the northeast, the Gunnison uplift to the south, and the Uncompahgre swell to the west (George 1927; Weiner and Haun 1960). Elevations within the Permit Coverage Area range from approximately 5,000 feet above mean sea level (amsl) along the Colorado River to 8,900 feet on Grass Mesa near the western edge of the unit area. Annual precipitation within the Permit Coverage Area ranges from 10 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 primary vegetation types in the Mamm Creek Unit are sagebrush shrublands (Artemisia tridentata), pinyon -juniper woodlands (Pinus edulis-Juniperus osteosperma), and Gambel oak shrublands (Quercus gambelii). A small amount of aspen is present at the southern and eastern edge of the Project Area. The riparian vegetation includes narrowleaf cottonwood (Populus angustifolia), mountain maple (Acer glabrum), river birch (Betula occidentalis), alder (Alnus incana spp. tenuifolia), dogwood (Cornus sereciea), and Woods' rose (Rosa woodsii). Snowberry occurs in the shrublayer, and orange sneezeweed (Dugaldia hoopesi(), tailcup lupine (Lupinus caudatus), field horsetail (Equisetum arvense), American vetch (Vicia americana), orchardgrass (Dactylis gloverata), northern bedstraw, geranium (Geranium caespitosum), and yarrow (Achillea lanulosa) occur in the understory. Further to the southwest, numerous blue spruce (Picea pungens) occur along the creek (BLM 2005). Vegetation within the Grass Mesa area primarily consists of hillsides dominated by pinyon -juniper woodlands (Juniperus osteosperma and Pinus edulis) and the mesa top dominated by mixed mountain shrubs, mostly big sagebrush (Artemisia tridentata), Gambel oak (Quercus gambelii), and serviceberry (Amelanchier alnifolia). Several of the proposed locations fall within areas dominated by sagebrush -steppe. Herbaceous and succulent species commonly found in the project area include arrow -leaf balsamroot (Balsamorhiza sagittata), prickly pear cactus (Opuntia polyacantha), prairie lupine (Lupinus wyethii), orange globemallow (Sphaeralcea munroana), and several species of penstemon (Penstemon spp.) and paintbrush (Castilleja spp.) (BLM 2004). \\encana.mm\ nvshared\South Rockies\Operations_South Piceance\Gathering Trunk Pipelines -Projects Mamm Creek\STORMWATERVAamm Creek SWMP (East Dry 2-6 Revised February 2008 The entire Mamm Creek 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 Mamm Creek 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 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 cut/fill 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 (Le., 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 Mamm Creek 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. \encana.com\dnvshared\Souh Rockies\Operations South Piceance\Gathering Trunk Pipelines -Projects Mamm Creek\STORMWATER%lamm Creek SWMP (East Dry 2-7 Revised February 2008 • 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. • 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. All streams in the Mamm Creek Unit are tributary to the Colorado River. The project area is located in the Mamm Creek watershed, and drained by Gant Gulch, Middle Mamm Creek, and an unnamed tributary to Middle Mamm Creek. Gant Gulch is tributary to West Mamm Creek. These drainages flow to the northeast into the mainstream portion of Mamm Creek. Mamm Creek is a perennial tributary to the Colorado River. \\encana.mm\dnvshared\Soulh_Rockles\Operations South Piceance\Gathering Trunk Pipelines-ProJedsWamm Creek \STORMWATERW amm Creek SWMP (East Dry 2-8 Revised February 2008 Floodplain habitat occurs along Middle Mamm Creek and East Mamm Creek, which are perennial streams within the Gant Gulch Area. Dry Hollow Creek is also within the Project Area. Riparian habitat is found along the banks of these streams. The riparian vegetation along Middle Mamm creek extends up to 100 feet on either side of the creek. The riparian habitats associated with Middle Mamm, East Mamm and Dry Hollow Creeks, have been determined to be "non-functional" or "functioning at risk" (M. Kinser, BLM, personal communication, September 2005) (BLM 2005). The Grass Mesa area is located within the watersheds of Dry Creek and Ramsey Gulch. Both of these creeks are tributaries to the Colorado River. Stream flows in the drainages within the Grass Mesa area are generally ephemeral and dependent on seasonal storm and snowmelt runoff. Floodplain habitats occur along the intermittent drainages within Dry Creek and Ramsey Gulch but no floodplain habitat would be impacted by the proposed action. Intermittent drainages occur along Dry Creek and Ramsey Gulch. However, no wetland habitats or riparian vegetation have been documented along these drainages (BLM 2004) 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; • 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 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, distances to streams, wetlands, irrigation ditches, canals, other surface waters, etc; • 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). \\encana.com\dnvshared\SaNh_Rockies\Operalions_South 2-9 Revised February 2008 Piceance\Gathering Trunk Pipelines-ProJectsWamm Creek \STORMWATERWamm Creek SWMP (East Dry 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. \\encana.com\dnvshared\South_Rockies\Operations_South Piceance\Gathering Trunk Pipelines-Projectswamm Creek \STORMWATER Mamm Creek SWMP (East Dry 3-1 Revised February 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 mobile 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. \\encana.com\dnvshared\SoWr Rockies\Operations South Piceance\Gathering Trunk Pipelines-Projeus\Mamm Creek\STORMWATER'Mamm Creek SWMP (East Dry 3-2 Revised February 2008 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 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): \\encana.mm\dm/shared \South_Rockies\Operations South Plceance\Gathering Trunk Pipelines-Projectswamm Creek\STORMWATER\Mamm Creek SWMP (East Dry 3-3 Revised February 2008 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. 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. \\encana.com\dnvshared\South_Rockies\Operations_South Plceance\Gathering Trunk Pipelines-Projectswamm Creek\STORMWATERN1amm Creek SWMP (East Dry 3-4 Revised February 2008 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...). • 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. 1\encana.mmltlnvshared\South Rockies\Operations South Plceance\Gathering Trunk Pipellnes-Projects\Mamm Creek\STORMWATER'Mamm Creek SWMP (East Dry 3-5 Revised February 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. \\encana.com\dnvshared\South__Rockies\Operations South Piceance\Gathering Trunk Pipelines-ProJectswamm Creek STORMWATERWamm Creek SWMP (East Dry 4-1 Revised February 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 \\ancana.com\dnvshared\South Rockies\Operations South 5-1 Revised February 2008 Piceance\Gathering Tank Pipelines-ProjectsWamm Creek\STORMWATERWamm Creek SMMP (East Dry be fully vegetated, erosion in these areas still occurs which requires maintenance activities such as regrading 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. \\encana.wm\dnvshared\SouthRockdes\OperalionsSouth Piceance\Gathering Trunk Pipelines -Projects Mamm Creek\STORMWATERvvtamm Creek SWMP (East Dry 5-2 Revised February 2008 • Reseeding of any bare spots where vegetation has failed to establish. • 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). \\encana.mm`dnvshared\South_Rackies\operations South Piceance\Gathering Trunk Pipelines -Projects \Mamm Creek\STORMWATERWamm Creek SWMP (East Dry 5-3 Revised February 2008 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.

GRI Project No. 2840 11 June 2008 Prepared by Carl E. Conner (Principal Investigator) and Barbara Davenport Grand River Institute P.O. Box 3543 Grand Junction, Colorado 81502 State of Colorado Antiquities Permit No. 2008-63 Submitted to Board of County Commissioners Garfield County, Colorado Abstract At the request of EnCana Oil and Gas (USA) Inc., Grand River Institute conducted a Class I cultural resources inventory for a Sensitive Area Study in relation to an anticipated Special Use Permit Application with Garfield County for the proposed East Dry Hollow Loop Phase I pipeline project. The study is for a linear route of 3.9 miles and is located in the Dry Hollow and West Divide Creeks area about 5.0 miles south of Silt, Colorado. The Class I inventory was undertaken to ensure the project's compliance with county, state, and federal laws and regulations governing the identification and protection of cultural resources on privately owned lands that will be affected by a government action. This work was performed under State of Colorado Antiquities Permit No. 2008-63. The purpose of the cultural resources investigation was to identify previously recorded resources within or near the project area that may be adversely affected by the proposed action and to evaluate the potential of additional such resources in the project arca. The Class I files search and report preparation were performed during the first two weeks of June 2008. Although sites occur near the project area, none have been recorded within 300 meters of the proposed pipeline. Accordingly, a determination of "no effect" for the project is recommended pursuant to Section 106 of the National Historic Preservation Act (36 CFR 800).

The linear route of 3.9 miles is located on private land in the Dry IHollow and West Divide Creeks area. This work was performed under Statc of Colorado Antiquities Permit No. 2008-62. Carl E. Conner, Principal Investigator, was assisted by archaeologist Barbara J. Davenport. The Class I files search and report preparation were performed during the first two weeks of June 2008. The Class I inventory was undertaken to ensure the project's compliance with state and federal legislation governing the identification and protection of cultural resources on privately owned lands that will be affected by a government action. It was done to meet requirements of the National Historic Preservation Act (as amended in 1992), the National Environmental Policy Act of 1969 (42 U.S.C. 4321), the Federal Land Policy and Management Act of 1976 (43 U.S.C. 1701), and the Archaeological Resources Protection Act of 1979 (16 I I.S.C. 470aa et seq., as amended), and Article 80.1, Colorado Revised Statutes. These laws are concemed with the identification, evaluation, and protection of fragile, non-renewable evidence of human activity, occupation, and endeavor reflected in districts, sites, structures, artifacts, objects, ruins, works of art, architecture, and natural features that were of importance in human events. Such resources tend to be localized and highly sensitive to disturbance. All work was performed according to guidelines set forth by the Office of Archaeology and Historic Preservation (OAHP) of the Colorado Historical Society. Location of the Project Area The study area is located approximately 5.0 miles south of Silt, Colorado. It lies in T. 6 S., R. 92 W., Sections 35 and 36; T. 7 S., R. 92 W., Sections I, 2, 3, 4, 10 and 1 I; 6'" P.M. (Figure 1). Environment The project area is within the Piceance Creek Basin, one of the major geologic subdivisions of Colorado. The Piceance Creek Basin is an elongate structural downwarp of the Colorado Plateau province that apparently began its subsidence approximately 70 million years ago during the Laramide Orogeny. Sediments from surrounding highlands were deposited in the basin, accumulating to a thickness of as much as 9000 feet by the lower Eocene epoch, when subsidence ceased. Regional uplift occurred in the Late Tertiary, and erosion of the area has continued since (Young and Young 1977:43-46). The Wasatch formation underlies the study arca. It consists of a series of interbedded variegated mudstones, sandstones, and siltstones of varying colors --brick red, tan, white, and purple. Forming after a period of erosion, the Wasatch is the first extensive continental deposit following those of the Cretaceous -age Mesaverde Group. 0 0- t0 0 J 0 271000 272000 273000 274000 276000 /4111 JA 6 S.

The project area rests on the benchland south of the Colorado River on the gently sloping ridges that border Dry Hollow and West Divide Creeks. Elevations average about 6000 feet. This relatively low elevation is host to a cool semiarid climate where temperatures can drop to - 10 degrees F during the winter and summer temperatures may reach 100 degrees E; there is a maximum of 120 frost free days and the annual precipitation is about 12 inches. The surrounding higher elevations are characterized as cooler and moister. Annually, the high mountain temperatures could average 5 degrees cooler and the precipitation as much as 14 inches greater that the surrounding low elevations (USDA 1978:244). There are several generalized vegetation communities in the area including riparian along the creeks, big sage and saltbush shrubland in the valley bottoms, and juniper/oak woodland on the surrounding mountain slopes. However, the prehistoric streamflow and habitats along Dry Hollow and West Divide Creeks have been significantly altered by historic EuroAmerican water diversions, reservoirs, and irrigation of agricultural fields. The valley bottoms have also changed due to infringement by pipelines, gravel operations, roadways and bridges. Ranchers currently use the area primarily for livestock grazing. Ground visibility ranges from 20% in the relatively recently undisturbed areas to about 90% in the cultivated fields and along the roads. These communities support a variety of wildlife species. Mule deer, elk, coyote, and black bear are common, as are cottontail rabbits, and various rodents. Mountain lion, bobcat, fox, skunk, badger, and weasel are also likely inhabitants. Bird species observed in the area include the wild turkey, jay, raven, red -shafted flicker, long-eared owl, and various raptors. Although the present day land use of the project area (including energy development, grazing, ranching and farming) has pushed some of the large mammals into the surrounding mountains, deer and wild turkeys make heavy use of the cultivated fields during the months of colder temperatures. Also, the creek contains several beaver ponds and wetlands that are supported primarily from snowmen, groundwater, springs, and irrigation runoff. Paleoclimate Relatively small changes in past climatic conditions altered the exploitative potential of an area and put stress upon aboriginal cultures by requiring adjustments in their subsistence patterns. Therefore, reconstruction of paleoenvironmental conditions is essential to the understanding of population movement and cultural change in prehistoric times (Euler et al. 1979). To interpret whatever changes are seen in the archaeological record, an account of fluctuations in past climatic conditions must be available or inferences must be made from studies done in surrounding area. Generally, only gross climatic trends have been established for western North America prior to 2000 BP (Antevs 1955; Berry and Berry 1986; Mehringer 1967; Madsen 1982; Wendlund and Bryson 1974; Peterson 1981). Scientific data derived from 3 investigations of prehistoric cultures and geoclimatic and bioclimatie conditions on the southern Colorado Plateau over the past two millennia have achieved a much greater degree of resolution (Dean et al. 1985). Files Search Results Cultural resource investigations in the region have yielded surface diagnostic artifacts and excavated cultural materials consistent with the regional cultural history. Evidence provided by chronometric diagnostic artifacts and radiocarbon analyses indicate regional occupation during the Paleoindian Era, Archaic Era, Formative Era, and Protohistoric Era. Historic records suggest occupation or use of the region by EuroAmerican trappers, settlers, miners, and ranchers as well. Overviews of the prehistory and history of the region are provided in documents published by the Colorado Council of Professional Archaeologists' entitled Colorado Prehistory: A Context for the Northern Colorado Plateau (Reed and Metcalf 1999), and by the Colorado Historical Society entitled Colorado Plateau Country Historic Context (Husband 1984). A file search for known cultural resources within the project area was made through the Colorado Historical Society's Office of Archaeology and Historic Preservation. This review identified seven reports that have been done in the general area, which are listed in Table 1. Table 1. List of projects previously conducted within about 1.0 mile of the study area.

Historic records also indicate a permanent Euro - American presence in the region began as early as the late 1880's. Notably, the prehistoric sites in the river corridor have been impacted by the 130 year occupation and use of the area by EuroAmericans. Notably, many of the newly and previously recorded resources in the general area indicate it was intensively occupicd during the Protohistoric Era. Unfortunately for many of the sites where wickiups were present, post -cutting and wood collection by the Historic EuroAmerican settlers and ranchers over the past 125 years has nearly wiped out evidence of their presence. Also, surface collection of diagnostic artifacts has impacted the sites and affected the assignment of cultural/temporal associations. In general, although the study area was probably not continuously occupied prehistorically, it seems to have offered an attractive environment for gathering, floral processing, hunting, as well as lithic procurement and processing. Site density in the surrounding mesa areas is high, probably due to two factors: good access to permanent water, and strategic topographical positioning on the ridge tops and open benches. Such camp placement provided a good view of the surrounding lower elevations for purposes of hunting and protection. The heavily vegetated canyon bottoms were accessed for reasons of acquiring water and for the procurement of floral and faunal resources. The apparent differences in the characteristics of the upland and lowland sites may be due to factors other than cultural selection. The lowland sites are subjected to more artifact collecting than the uplands, and the areas along the Colorado River have been subject to few cultural resource surveys. The upland area exhibits a very thick vegetation cover that may be limiting discovery of features and additional artifacts. Lowland sites exhibit greater variability in site types. While the uplands are limited to isolated finds, open camps, and lithic scatters; the lowlands contain these site types and open architectural sites, sheltered sites, and a single tool stone procurement area. The lowland sites contain higher frequencies of cultural features or evidence of features. These features include fire -cracked rock scatters, charcoal stains, hearths, stone structures, and wickiups. All of the prehistoric sites contain low numbers of artifacts, including very limited numbers of debitage, bifacial tools and expedient tools. This suggests conservation, curation, and reuse of flaked stone tools in an area where tool material sources are limited. Lowland sites tend to be situated in the pinyon juniper vegetation community in greater frequencies than is suggested by the relative proportion of the pinyon juniper to other vegetation communities. The sites in the uplands are distributed proportionally to the size of the vegetation 6 communities, with the mountain shrub and sagebrush communities exhibiting the highest site density. Too little is known of the age of the sites to make any definitive statements. The distribution of site ages based on projectile points and ceramics is generally the same as portrayed in Reed and Metcalf (1999), but the lack of absolute dating precludes any conclusions in this area. Lithic scatters exhibit a smaller site size than open camps in both the lowland and upland settings. Isolated finds are distributed across a wider range of slopes than lithie scatters or open camps. The differences in the type and distribution of historic sites are: Sites in the uplands are limited to sheep and cattic raising activities and arc primarily post -1889. Sites in the uplands are distributed proportionally to the size of the vegetation communities, with the mountain shrub and sagebrush communities exhibiting the highest site density. Sites in the lowlands display a greater diversity in types and are found mainly in the pinyon juniper and sagebrush zones. The historic sites in the lowlands are concentrated near transportation corridors and near permanent water sources, particularly the habitation sites. Sites indicative of particular economic activities are spread across the landscape. During 1980, the BLM 's Glenwood Springs Resource Area was subject to an archaeological survey that randomly sampled three percent of its managed lands. A total of 17,400 acres was surveyed for cultural resources. As a result, 58 prehistoric sites and 2 historic sites were recorded, an average of about 2 sites per section (.0034/acre). Three types of prehistoric sites were distinguished by the study; limited activity areas, short-term camps, and large habitation sites. These were classified on the basis of site size and the diversity of artifacts/activities represented. Notably, the sites were unevenly distributed and varied by vegetation community. The highest site density, about 5.0 sites/section (.0078/acre), occurred in pinyon/juniper and sagebrush communities. Concurrently, the greatest number of sites located during the survey tended to occur in or near the pinyon/juniper community. Other environmental factors found to be important during the statistical analysis of the settlement patterns included 1) vertical distance between the site and the primary water source is a greater controlling factor that the horizontal distance, 2) sites tend to be near or on points of vantage, 3) sites tend to be located in forested areas, preferably with a southern exposure and, 4) sites tend to occur on flat ground (less than 40% grade) in areas of relatively low surface relief (Burgess et al. 1980:108-120, 138- 139). In general, the region exhibits a relatively low site density and sites tend to cluster near permanent water sources. Relevant Historical Background post -1880 The Ute people occupied large areas of Western Colorado until about 1881. Due to the White River Ute's discontent that lead to the "Meeker Massacre," as the incident became know, a congressional investigation lead to the Treaty of 1880 that stipulated the removal of the White River bands to the Uintah Reservation in northeastern Utah. The Uncompahgre band was to be 7 given a small reservation in the vicinity of the confluence of the Colorado and Gunnison Rivers. Aware of the value of these agricultural lands, however, the commission charged with enforcing the terms of the treaty, under the direction of Otto Mears, manipulated the location process using a loophole in the treaty language, and the Uncompahgres were given lands in Utah near the Uintah Reservation. The Southern Ute bands were left on the small reservation in southwestem Colorado that had been given them by the Treaty of 1873. On 1 September 1881, the last of the Utes were moved to their new reservations in Utah, and western Colorado was completely opened to the whites. Interest in the potential agricultural lands of western Colorado (namely the Uncompahgre, Gunnison, Colorado, Dolores, San Miguel, White, and La Plata River valleys) had been growing for some time prior to the Utes' banishment, and by the spring of 1881 frontier towns closest to the Ute lands were "crowded with people, anxious to enter the Reservation and take possession of the most desirable locations (Haskell 1886:2)." Only days after the last of the Utes had been expelled, settlers began rushing onto the reservation lands. Settlement activity spread quickly -- during the autumn months of 1881 land claims were staked, townsites were chosen, and railroad routes were surveyed (Haskell 1886, Borland 1952, Rait 1932). However, because the former reservation lands were not officially declared public lands until August 1882, the first year of settlement activity was marked by a degree of uncertainty regarding the legality of land claims. When finally announced, the 1882 declaration did not allow home -stead entries on the newly opened lands, but only pre-emptions, or cash entries, at the rate of $1.25 per acre for agricultural land, $5.00 per acre for mineral land (Borland 1952:75). By 1895, the major portion of the land along Mamm Creek had been claimed, mostly under Cash Entry patents. The settlers raised their own food and availed themselves of the plentiful game in the area. Gardens, hay fields, and orchards were planted, and irrigation ditches were dug to divert the creek's water to cultivated fields. Large herds of cattle and sheep were accumulating, grazing the valley floor and the vast open range above, driven to the uplands via trails leading up the various gulches. Because the area was still fairly remote, competition for lands had not yet begun. Travel in and out of the Rifle area was restricted to horse and/or wagon. There were several well-developed Ute trails, and in the early 1880s, the federal government had built the aforementioned road between the White and Grand Valleys. In 1885 a toll road opened along the Grand River between Rifle and Grand Junction; prior to the building of this road through DeBeque Canyon, the route to Grand Junction had been a two-week joumey "through the Cedar Hills, up Kimball Creek...down the "Sawtooth Range to Fruita and then back to Grand Junction" (Murray 1973:5). But, despite this network of trails and roads, Parachute remained pretty much isolated. With the coming of the D&RG railroad in 1890, however, new pressures were brought to the area. More and more settlers arrived, competing not only for arable land but also for grazing privileges on the unpatented public domain of the surrounding uplands. Increasing numbers of 8 cattle and sheep were imported, some being run as commission cattle for outside investors (ibid:84). Open warfare between cattle and sheep ranchers ensued, resulting in the slaughter of thousands of animals. Four thousand sheep belonging to Messrs. Starkey and Charlie Brown were killed by masked men who tried to drive the animals over cliffs at the head of a Clear Creek tributary and above the Grantee Schoolhouse (LaPoint et al. 1981:3-51). Another 4000 sheep belonging to J.B. Hurlburt were driven to their deaths above Ben Good Creek, a tributary of East Fork. The animosity between cattlemen and sheepmen continued into the 1900s. Finally, Congress passed the Taylor Grazing Act in 1934, bringing to an end to the free range by providing for regulated grazing and an end to the Sheep -Cattle Wars. Cash Entry, Desert Land, and Homestead patents continued to be granted into the 1920s and 30s. Ranching and farming were still the most important economic activities in the Parachute area and remained so until the 1960s and 1970s when many of the farms and ranches of the region were bought up by large companies interested in the large-scale extraction of oil shale and natural gas. Summary and Recommendations The National Historic Preservation Act of 1966 (NHPA) directs that federal agencies protect cultural resources that possess significant values. Significance is a quality of cultural resource properties that qualifies them for inclusion in the NRNP. The statements of significance included in this report are field assessments that support management recommendations to the State Historic Preservation Officer (SHPO). The final determination of site significance is made by the controlling agency in consultation with the SHPO. The Code of Federal Regulations was used as a guide for site evaluations. Titles 36 CFR 50, 36 CFR 800, and 36 CFR 64 are concerned with the concepts of significance and (possible) historic value of cultural resources. Titles 36 CFR 65 and 36 CFR 66 provide standards for the conduct of significant and scientific data recovery activities. Finally, Title 36 CFR 60.6 establishes the measure of significance that is critical to the determination of a site's NRNP eligibility, which is used to assess a site's research potential: The quality of significance in American history, architecture, archaeology, and culture is present in districts, sites, buildings, structures, and objects of State and local importance that possess integrity of location, design, setting, materials, workmanship, feeling, and association, and a) that are associated with events that have made a significant contribution to the broad patterns of history; or b) that are associated with the lives of persons significant in our past; or c) that embody the distinctive characteristics of a type, period, or method of construction, or that represent the work of a master, or that possess high artistic values, or that represent a significant and distinguishable entity whose components may lack individual distinction; or d) that have yielded, or may be likely to yield, information important in the prehistory or history. 9 The eligibility determination and consultation process is guided by Section 106 of the NI -IPA (36 CFR 60, 63, and 800). Final determinations of National Register eligibility and effect are made by the controlling agencies in consultation with the State Historic Preservation Officer. The Class T files search and report preparation were performed during the first two weeks of June 2008. Although sites occur in the general area, none have been recorded within 0.4 mile of the proposed pipeline. Accordingly, a determination of "no effect" for the project is recommended pursuant to Section 106 of the National Historic Preservation Act (36 CFR 800). 10 References Antevs, E. 1955 Geologic -climate dating in the west.

Prepared for: EnCana Oil and Gas (USA), Inc. Parachute, Colorado Prepared by: WestWater Engineering 2570 Foresight Circle #1 Grand Junction, CO 81505 August 2008 1.0 INTRODUCTION 1.1 Project Description EnCana Oil and Gas (USA), Inc. (EnCana) has requested WestWater Engineering (W WE) to provide an "Integrated Vegetation and Noxious Weed Management Plan" for a proposed "special use permit" in Garfield County, Colorado. EnCana is seeking the special use permit to install an additional section of gas pipeline to the existing EnCana East Dry Hollow Loop Phase I pipeline (Figure 1). An "Integrated Vegetation and Noxious Weed Management Plan" was previously prepared for the existing Phase 1 pipeline in March 2008. This current report is an Addendum to the March 2008 report and pertains to the additional proposed pipeline section. Descriptions of vegetation, soil type, landscape, setting and noxious weeds, as well as control practices and reclamation recommendations, are presented in the March 2008 report and apply to the pipeline extension unless otherwise noted. This Addendum to the March 2008 report describes updated resource features and observations documented during a recent field survey of the additional pipeline extension. The pipeline extension begins at the EnCana P4 well pad, approximately .75 miles west of Garfield County Road 331 (CR 331) in Dry Hollow Creek, and extends generally eastward about 8296 feet (1.57 miles) to the EnCana/Eubanks property boundary (Figure 1). The Elm/atlas/Eubanks twycty line, at the pipeline extension terminus, .i:3 approximately .7 miles east of CR 331. The pipeline extension is situated within Sections 2, 3, 4, 10 and 11 of T7S, R92W, of the 6th P.M., Garfield County, Colorado (Figure 1). The potential area of disturbance for the additional pipeline section is approximately 10.5-11.0 acres based upon a 55-60 foot construction right-of-way. 2.0 LANDSCAPE SETTING 2.1 Vegetation Communities The predominant vegetation community along the pipeline route consists of open irrigated and dry -land meadows planted with alfalfa and various introduced grass species. Adjacent slopes and ridges are vegetated with piflon pine (Pinus edulis), Utah juniper (Juniperus utahensis), sagebrush (Artemesia tridentata), rabbitbrush (Chrysothamnus nauseosus) and wheatgrass (Pascopyrum spp.). The riparian area adjacent to Dry Hollow Creek contains cottonwood (Populus spp.), bluegrass (Poa spp.), brome grass (Bromus spp.), reed canarygrass (Phalaroides arundinacea), saltgrass (Distichlis spp.) and scattered big basin sagebrush (Artemesia tridentata tridentata). Downy brome (Bromus tectorum) was observed as the dominant grass species in non -irrigated areas and along the previously disturbed pipeline corridor 2.2 Soil Types Associated soil types are discussed in the March 2008 report. Two additional soil types are associated with the pipeline addendum (NRCS 2008). Heldt-Clay-Loam occurs in valley sides and alluvial fans of 3 to 6 percent slopes; has severe limitations for land capability; requires special conservation measures; and is primarily used for grazing, recreation and wildlife habitat. The Torrifluents soil type occurs on near -level terrain in flood plains and tributaries; has severe limitations for land use; and is primarily used for grazing, forestland and wildlife habitat. The WestWater Engineering Page 1 of 9 8/20/2008 native vegetation of the Heldt-Clay-Loam soil is typically westem wheatgrass (Pascopyrum smithii), big sagebrush (Artemesia tridentata spp.) and rabbitbrush (Chrysothamnus spp.). The vegetation generally associated with Torrifluents is grass spp., cottonwood (Populus spp.), willow (Salix spp.), sedge (Carex spp.) and rush (Juncus spp.). 3.0 NOXIOUS WEEDS Section 3.0 of the March 2008 report discusses general noxious weed concerns, need for management and species listings by the State of Colorado and Garfield County. The discussions provided in Section 3.0 of the March 2008 report are applicable to the proposed pipeline extension described in this report addendum. 3.1 Survey Methods WWE conducted the surveys of the additional pipeline section on August 18, 2008. Ground and climate conditions were dry and visibility of resource features was excellent. The purposes of the surveys were to identify vegetation communities and to search for, identify, and map noxious weed species. Factors considered include soil type and texture, existing land management, absence or presence of plant species, and the present natural vegetation community. Vegetation types were determined through field identification of plants, aerial photography, and on -the -ground assessments of plant abundance visible during the survey. Identification of plant species was aided by using pertinent published field guides (Whitson et al. 2001, CWMA 2007, Kershaw et al. 1998). Locations of weeds and other features included in this report were recorded with the aid of a handheld global positioning system instrument (GPS) using NAD83/WGS84 map datum, with all coordinate locations based on the Universal Transverse Mercator (UTM) coordinate system in Zone 135. Recorded noxious weed locations and general densities are presented in Appendix A. 3.2 Observations This report includes weeds found during the additional surveys by WWE biologists. Numerous weed populations were observed along the alignment for the pipeline extension, primarily within previously disturbed areas. Garfield County listed noxious weeds observed included chicory, common burdock, musk thistle, Russian knapweed, and salt cedar tamarisk (Table 1). The most prevalent listed weed species observed was Russian knapweed (Photo 1). Russian thistle, kochia and cheatgrass (Photos 2 and 3) were the most prevalent weeds observed, though not specifically listed by Garfield County. Other weeds noted during the survey were clasping pepperweed and field bindweed (Photo 1). Locations of Garfield County listed noxious weeds observed during the surveys are presented in Figure 1 and Appendix A. WestWater Engineering Page 2 of 9 8/20/2008 Table I.

WestWater Engineering Page 6 of 9 8/20/2008 3.3 Treatment and Control of Noxious Weed Infestations From the noxious weed list developed by the State of Colorado (8 CCR 1203-19), Garfield County has designated 24 weeds to be controlled in its jurisdiction (Table 1 of March 2008 report). Five weed species from the Garfield County list were found in or near the proposed pipeline ROW and are indicated by bold type in Table 1 of this current report. Included in Table 1 are weed life cycle type, state listing category, and recommended control method for each weed species. Those in regular type were also observed during the survey and are listed by the State of Colorado as noted (CWMA 2007). Problematic weeds not listed by Garfield County or the state, such as Russian histle and kochia, were observed along the pipeline ROW and can have an adverse impart nn reclamation effnrts through competition for moisture with desirable species. 3.4 Recommended Treatment Strategies Section 3.4 of the March 2008 report, which is applicable to the proposed pipeline extension described in this report addendum, outlines and discusses recommended treatment strategies for controlling noxious weeds 1.5 T life epic. -nd Mouagement CAct:dor s Section 3.5 of the March 2008 report, which is applicable to the proposed pipeline extension, outlines and discusses noxious weed life cycles and management calendars for thistle species and salt cedar. 3.6 Commercial Applicator Recommendations Section 3.6 of the March 2008 report, which is applicable to the proposed pipeline extension outlines and discusses recommendations for the use of a commercial applicator when controlling noxious weeds. 3.7 Best Management Practices — Noxious Weeds Section 3.7 of the March 2008 report, which is applicable to the proposed pipeline extension, outlines and discusses "best management practices" for controlling noxious weeds. 4.0 REVEGETATION - RECLAMATION 4.1 Pipeline ROW The pipeline extension traverses a variety of terrain including open irrigated and dry -land meadows, small intermittent drainages, the riparian area of Dry Hollow Creek and adjacent rocky slopes. The majority of the pipeline route follows an existing gas pipeline that has previously been disturbed (Cover Photo). The pipeline extension will disturb an area approximately 55-60 feet in width for a length of about 1.57 mile resulting in approximately 10.5-11.0 acres of disturbance. The vegetation ranges from irrigated alfalfa meadows to varying WestWater Engineering Page 7 of 9 8/20/2008 non -irrigated native vegetation depending on the site. Successful reclamation of the project area is dependent upon soil type and texture, aspect, slope, proper weed control and revegetation with suitable plant species. The August 2008 survey noted Garfield County listed weed species such as chicory, common burdock, musk thistle, Russian knapweed and salt cedar tamarisk in the pipeline ROW. Other problematic weeds noted were Russian thistle, kochia, clasping pepperweed and field bindweed. Construction of the new pipeline extension will create a new disturbance that could allow additional weeds to gain a foothold unless an effective monitoring and weed control program is implemented. The report of March 2008, Section 4.1, discusses recommended seed mixes and reclamation measures that are applicable to the new pipeline extension described in this report addendum.

Prepared For: EnCana Oil and Gas (USA), Inc. Prepared by: WestWater Engineering 2570 Foresight Circle #1 Grand Junction, CO 81505 August 2008 WestWater Engineering INTRODUCTION EnCana Oil and Gas (USA), Inc. (EnCana) has requested WestWater Engineering (WWE) to provide a "Wildlife Impact and Sensitive Areas Report" for a proposed "special use permit" in Garfield County, Colorado. EnCana is seeking the special use permit to install an additional section of 16 -inch gas pipeline to the existing EnCana East Dry Hollow Loop Phase I pipeline (Figure 1). A "Wildlife Impact and Sensitive Areas Report" was previously prepared for the existing Phase I pipeline in March 2008. This current report is an Addendum to the March 2008 report and pertains to the additional proposed pipeline section. Descriptions of background information, landscape, setting, wildlife and sensitive species, as well as mitigation measures suggested to off -set potential impacts, are presented in the March 2008 report and amity to the pipeline extension unless otherwise noted. This Addendum to the March 2008 report describes updated resource features and observations documented during a recent field survey within the additional pipeline section. WWE conducted the surveys of the additional pipeline section on August 18, 2008. Ground and climate conditions were dry and visibility of resource features was excellent. WWE biologists surveyed an area 60 feet from the center line on both sides of the proposed pipeline. The purposes of the surveys were to determine those wildlife and sensitive plant species that occupy the project area at varying periods during the year and which would potentially be impacted as a result of the pipeline construction and operational activities. Factors considered include coil type and texture, existing land management, absence or presence of wildlife and plant species, habitat designations by Federal and State wildlife agencies, and the present natural vegetation community. Locations of biological features included in this report were recorded with the aid of a handheld global positioning system instrument (GPS) using NAD83/WGS84 map datum, with all coordinate locations based on the Universal Transverse Mercator (UTM) coordinate system in Zone 13S. The additional pipeline section begins at the EnCana P4 well pad, approximately .75 miles west of Garfield County Road 331 (CR 331) in Dry Hollow Creek, and extends generally eastward about 8296 feet (1.57 miles) to the EnCana/Eubanks property boundary (Figure 1). The Encana/Eubanks property line, at the pipeline terminus, lies approximately .7 miles east of CR 331. The additional pipeline segment is situated within Sections 2, 3, 4, 10 and 11 of T7S, R92W, of the 6th P.M., Garfield County, Colorado (Figure 1). The potential area of disturbance for the additional pipeline section is approximately 10.5-11.0 acres based upon a 55-60 foot construction right-of-way. WestWater Engineering 1 8/20/2008 LANDSCAPE SETTING General Description The proposed additional pipeline is located on private lands, about 6.0 to 7.0 miles southeast of the Town of Rifle; and is about 4.5 to 5.0 miles south of the Colorado River. Beginning at the EnCana P4E well pad, the pipeline traverses generally eastward through an open dry -land meadow, a narrow stand of pinon/juniper and irrigated meadows while following an existing gas pipeline to the EnCana N3E well pad. The pipeline then follows an existing gas field road generally south and eastward through irrigated meadows and then descends a steep rocky slope along an existing access road to the Dry Hollow Creek drainage crossing. The pipeline then crosses Dry Hollow Creek, continues south for a few hundred feet through rangeland and agricultural land, and then turns east to the CR 331 crossing. From CR 331 the pipeline section travels east along an existing gas pipeline through agricultural fields, approximately .7 miles, to its terminus at the EnCana/Eubanks property line. The topography in the pipeline extension consists generally of flat to rolling meadows. The Dry Hollow Creek drainage is bordered by moderately steep hillsides that rise about 100 feet to low mesas. The terrain west of the Dry Hollow Creek pipeline crossing is moderately steep while the terrain to the east rises gradually within a drainage containing irrigated meadows. Elevations of the pipeline extension range from 5,960 to 6,150 feet. Numerous natural gas well pads are adjacent to the pipeline extension. Rural residences are widely spaced in the vicinity of the proposed pipeline extension along County Road 331 and east toward the pipeline terminus. The primary use of the surrounding area of the pipeline is agriculture/rangeland, wildlife habitat and recent natural gas extraction/development. Soils Associated soil types are discussed in the March 2008 report. Two additional soil types are associated with the pipeline addendum (NRCS 2008). Heldt-Clay-Loam occurs in valley sides and alluvial fans of 3 to 6 percent slopes; and has severe limitations for land capability; requires special conservation measures; and is primarily used for grazing, recreation and wildlife habitat. The Torrifluents soil type occurs on near -level terrain in flood plains and tributaries; has severe limitations for land use; and is primarily used for grazing, forestland and wildlife habitat. The native vegetation of the Heldt-Clay-Loam soil is typically western wheatgrass (Pascopyrum smithii), big sagebrush (Artemesia tridentata spp.) and rabbitbrush (Chrysothamnus spp.). The vegetation generally associated with Torrifluents is grass spp., cottonwood (Populus spp.), willow (Salix spp.), sedge (Carex spp.) and rush (Juncus spp.). Vegetation The predominant vegetation community along the pipeline route consists of open irrigated and dry -land meadows planted with alfalfa and various introduced grass species. Adjacent slopes and ridges are vegetated with pifion pine (Pinus edulis), Utah juniper (Juniperus utahensis), sagebrush (Artemesia tridentata) , rabbitbrush (Chrysothamnus nauseosus) and wheatgrass (Pascopyrum spp.). The riparian area adjacent to Dry Hollow Creek contains cottonwood WestWater Engineering 3 (Populus spp.), bluegrass (Poa spp.), brome grass (Bromus spp.), reed canarygrass (Phalaroides arundinacea), saltgrass (Distichlis spp.) and scattered big basin sagebrush (Artemesia tridentata tridentata). Cheatgrass (Bromus tectorum) was observed as the dominant grass species in non- irrigated areas and along the previously disturbed pipeline corridor. RESULTS OF SURVEY TESS Plant Species One special statue plant species and its habitat, Harrington beardtongue, that may be present in the project area, is listed in Table 1. It should be noted that Table 1 of the March 2008 report incorrectly listed the Harrington beardtongue as a Federal Candidate Species (USFWS 2008). Harrington beardtongue is considered a sensitive plant species by the Bureau of Land Management and U.S. Forest Service and is not under candidate consideration by the U.S. Fish and Wildlife Service. Table 1. Potential BLM and FS sensitive plant species Scientific Name Common Name Habitat Preference Penstemon est : bt„ .. Harrington t,__.a,�.,b_P Rocky loam, rocky clay loam derived from coarse calcareous parent ` materials; open sagebrush or, less commonly, piton -juniper. Elev. 6500-9,200 ft. Found in Garfield County on Grass Mesa. Results: No TESS plant species and/or their habitats were observed within the survey area of the proposed pipeline extension. The highest elevation of project area is approximately 6,150 feet, about 300 feet below the known lower elevation limit for Harrington beardtongue (Penstemon Haringtonii) (Spackman et al. 1997). Federal Listed Threatened, Endangered, Candidate Wildlife Species No federal listed threatened, endangered or candidate wildlife species occupy the area of the proposed pipeline extension and, thus, none of these species will be affected as a result of the proposed project. Habitats for these species do not occur on the project site or the immediate area. State Listed Threatened, Endangered Special Concern Wildlife Species During the surveys no state listed threatened or endangered wildlife species were observed in the area of the proposed pipeline extension. Bald Eagle may visit areas along Dry Hollow Creek and adjacent mesas and slopes in search of winter forage in the form of fish and dead animal carcasses. No Kit Fox denning sites were observed in the area of the pipeline extension. Potential foraging habitat for Kit Fox occurs within the area of the pipeline extension. Habitats for bat species for roosting, breeding and hibernating, in the form of caves, mine shafts, walls and cliffs, do not occur in the immediate vicinity of the pipeline extension. Townsend's Big - eared Bat can occur in the area while foraging. Potential habitat occurs along the stream corridor of Dry Hollow Creek for Northern Leopard Frog. Breeding habitats for Northern Leopard Frog, WestWater Engineering 4 in the form of shallow and quiet areas of water, do not occur in the area of disturbance for the pipeline extension. Birds of Conservation Concern (BOCC) Raptors: Numerous pinon pine and Utah juniper within .25 miles of the pipeline extension are of sufficient height and density for tree nesting raptors. The rock outcrops west of Dry Hollow Creek by the CR 331 pipeline crossing, and, north of the pipeline alignment by the EnCana P3 well pad are suitable for raptor nesting. One raptor cliff nest, likely of a Red-tailed Hawk (RTHA-2), was observed in the rock outcrop west of the CR 331 crossing, west of Dry Hollow Creek (Photo 1). This nest appeared active during the 2008 nesting season with fresh sticks and whitewash present at the nest site; no raptors were observed at the nest site. The general raptor nesting season has recently ended (August 15) and any young produced at this nest location have probably fledged and attained independence. Figure 1 illustrates the new raptor nest location for RTHA-2. One Red-tailed Hawk was observed foraging in the area of the EnCana N3E well pad. Raptor nest locations for the pipeline extension are reported as follows: RTHA-2 (UTM 13s 271770mE, 4372459mN): Nest is in a rock outcrop west of proposed pipeline extension, nest diameter = 28-30 inches, nest depth = 12 inches, slope = 100 per cent, aspect = 100 degrees. Nest is likely that of a Red-tailed Hawk. Status is likely active for 2008. Photo 1. Red-tailed Hawk Cliff Nest West of CR 331 Pipeline Crossing. WestWater Engineering 5 5 Birds of Conservation Concern (BOCC) other than raptors: The few stands of pinon/ juniper woodland associated with the project area are suitable nesting habitats for Pinyon Jay and Black -throated Gray Warbler. Pinyon Jays were observed north of the pipeline extension in the pinon/juniper northwest of the EnCana P3 well pad. Terrestrial Species American Elk and Mule Deer: For elk the pipeline segments within Sections 3, 10 and 11 are within a winter concentration area (CDOW 2008). For mule deer, the pipeline extension is situated in severe winter range; and the pipeline segments within Sections 3, 10 and 11 are within a winter concentration area (CDOW 2008). During the surveys deer fecal pellets were observed in areas where sagebrush and/or pinon pine and juniper trees were present. One deer was observed in the meadow area east of the EnCanaP4E well pad. For the project area, during winter periods when deep snow covers low-lying vegetation, mule deer rely on the existing sagebrush above the snow for their primary food source, while elk rely primarily on available grasses for food. Adjacent areas of pifion pine and juniper trees provide necessary escape, thermal and loafing cover for deer and elk. Other Bird Species: The project area's sagebrush, rabbitbrush, pillion pine, Utah juniper, riparian and grass under stories provide nesting and foraging habitats for various other migratory and non -migratory bird species, depending on the season of the year. Bird species observed during the additional surveys included House Finch, Blue -gray Gnatcatcher, Rock Wren and Mourning Dove. Reptiles: Plateau lizard was observed in the rocky terrain and pifion/juniper south of the pipeline extension, south of the EnCana P3 well pad. Aquatic Species Amphibians: Potential habitat for Northern Leopard Frog occurs along the stream corridor of Dry Hollow Creek. Breeding habitat for Northern Leopard Frog was not observed in the area of the creek crossing at Dry Hollow Creek. Fish: No fish inventories were conducted as part of this survey. Dry Hollow Creek, at the area of the pipeline project, apparently has never have been surveyed for fish species (Elmblad 2008, pers. comm.). Therefore, it is not certain if fish species occur in Dry Hollow Creek at the area of the pipeline project. Water flows in Dry Hollow Creek were observed at the time of WWE field surveys and this stream likely supports aquatic invertebrates. Fish species do occur in the Colorado River that lies approximately 4.5 miles north of the project site. The soils of the pipeline extension and adjacent drainages exhibit a high degree of erosion, which periodically affects silt loads and water quality of the Colorado River during significant runoff events. WestWater Engineering 6 IMPACTS TO WILDLIFE Wildlife Impact Assessment Construction of the pipeline extension will directly disturb approximately 10.5-11.0 acres of vegetation and wildlife habitat. Foreseen impacts would be (1) the loss of winter range to a small number of mule deer and elk that utilize this site, (2) the loss of foraging and nesting vegetation/habitat to a small number of bird species, and (3) the possible disturbance to a raptor nest west of Dry Hollow Creek, depending on the time period of construction. Further impacts to wildlife are discussed in the March 2008 report. MITIGATION RECOMMENDATIONS The "Mitigation Recommendations" that are outlined in the March 2008 report apply to the proposed pipeline extension described in this report. REFERENCES CDOW. 2008.

(EnCana) the following information as it relates to spill incidents: • Reporting requirements; • Initial spill response procedures; • How to access emergency response procedures; and • Initial remediation techniques. This document is intended to provide operations personnel with sufficient information so they can readily assess a spill, know which government agency to report to, what to report, and how to address the spill. This document only covers spills that are "manageable" with the tools and resources that operations personnel have readily available to them. The document does not cover unmanageable or catastrophic spills that require specialized expertise and equipment. Regardless of the size or type of spill, if difficulties or uncertainties arise, contact EnCana's Parachute, Colorado Office staff for advice and assistance. Please refer to the contact information provided in Section 2.1. This Project Specific Spill Response Plan covers spills associated with construction, drilling, completion and production operations and services associated with them. A copy of this Project Specific Spill Response Plan is on file at the following locations: EnCana Oil & Gas (USA), Inc. Parachute, Colorado Office EnCana Spill Plan Emergency Response May 2008 1 2.0 SPILL PREVENTION Care should be taken to prevent spills, leaks and releases. Two variables must be considered if a release occurs: Rate of flow: Is variable, depending on size and location of the related failure. Maximum expected potential rate of flow is not anticipated to exceed the amount of total liquid per day transferred using the pipeline. Personnel routinely perform visual inspections of piping to detect any failures. Total quantity of fluid that could be discharged: Is variable, depending on the rate of flow though the pipeline and the location of the failure. The maximum potential release would not exceed the volume for the pipeline and tank of the fluid being transferred. EnCana has engineering controls and management practices in place to prevent spills. Secondary containment is provided for oil spills at permanent facilities. For temporary surface pipelines EnCana has designed the pipeline with block valves which isolate sections of the pipeline to limit a release should one occur. Storage tanks are designed with isolation valves to ensure containment. EnCana's standard operating procedures require that any fluid transfer though temporary surface pipelines will be manned 24-hour a day until the transfer has been completed. If a spill is discovered then the following actions and reporting will be initiated immediately. EnCana Spill Plan Emergency Response May 2008 2 3.0 SPILL REPORTING PROCEDURES Spill reporting is an important part of environmental management. There can be fines and penalties imposed upon a company for not reporting a spill if it is considered a `reportable" occurrence under the legislation. This plan outlines when a spill is reportable, and to whom the spill must be reported. In addition to reporting to regulators, EnCana's personnel must be informed, and an incident/accident report completed and submitted to the EnCana's Parachute, Colorado Office. 3.1 INTERNAL NOTIFICATION Field personnel are to notify the EnCana's Parachute, Colorado office staff immediately upon locating a spill, release, or an unnatural event. The EnCana's Parachute, Colorado office staff will notify the required local, federal and state agencies.

Reportable spills are defined as: • ANY spill or release that may impact waters of the State. These spills are reportable as soon as practicable. • Any spills in excess of 20 barrels (840 US gallons) are reportable within 24 hours. • Any spills in excess of five barrels (210 US gallons) are reportable within ten days. In addition, the following types of spills are reportable. Spills that may cause an adverse effect to the environment. An adverse effect is defined as "impairment of or damage to the environment, human health, or safety or property. " Specifically, it is considered the following: • Spill is confirmed to have moved off -location (including vertical migration to water table); • Contaminants are present off -location at levels generally accepted to be problematic to soil, groundwater, livestock, and vegetation. This includes third party impact such as vegetation damage, and livestock impact; • Release is into surface water or a watercourse and moves off location; • Release or spill has potential for offsite odor complaints; and • Potential for toxic or flammable release to air going offsite. For assistance in determining if a release can be classified as an "adverse effect" or "potentially hazardous to the environment", contact EnCana's Parachute, Colorado Office Staff (See contact information provided in Section 2.1). 4.1.2. CHEMICAL AND REFINED HYDROCARBON SPILL Spills of production chemicals, fuels, lubricating oils as well as other refined hydrocarbons require reporting. Reporting of ANY AMOUNT of chemicals identified as toxic substances is required. Most of these compounds are associated with the downstream refining end of the petroleum industry, and are therefore not dealt with in detail in this report. EnCana Spill Plan Emergency Response May 2008 4 4.1.2.1 Release into Water A release of ANY AMOUNT of a chemical into surface water, a watercourse or groundwater that can cause an adverse effect on the environment must be immediately reported. Typically this means water found external to a containment berm. The regulations require reporting of any amount that can cause an adverse effect. This effectively means any chemical, fuel or lubricant used in construction; drilling, completion and production operations that are spilled into surface water must be reported. The regulatory authority then decides if any further action is required. 4.1.2.2 Releases onto the Ground A release of chemical or fuels onto the ground below the State of Colorado thresholds may still be reportable. Contact the EnCana's Parachute, Colorado Office staff for specific chemical releases. 4.1.3 CUMULATIVE RELEASES Cumulative releases involve the slow release of material over a sufficiently long time that the volumes eventually become significant and represent a potential risk to the environment. Cumulative releases that typically occur at our operations are associated with load outs, tank farms, pits, etc. and are relatively confined, therefore not causing a "significant environmental effect". Although the reporting of cumulative releases is required if they are causing a significant environmental effect, it should only be done in consultation with EnCana's Parachute, Colorado Office staff. 4.2 WHO IS TO REPORT? When an operator, maintenance person or other employee discovers a reportable spill, the area supervisor of EnCana's Parachute, Colorado Office staff must be notified immediately. The area supervisor must immediately contact EnCana's Parachute, Colorado Office staff, who will contact the appropriate government agency to report the spill (see Table 1 below). EnCana's employees and contractors are not to contact regulators unless directed to do so by their manager. 4.3 WHEN TO REPORT AND WHAT TO REPORT? A release should be reported to the appropriate government agency as soon as it is discovered or at the first available opportunity. The requirement for reporting is both verbal and written depending on the severity of the spill. Government authorities will advise if a written report is required at the time the verbal report is provided. Reporting personnel should make a point of inquiring about the need for a written report. The Table on page 10 outlines the specific information to be provided verbally and in written reports for spills of oil, condensate and produced water, as well as spills of chemicals and refined hydrocarbons. Verbal reports are provided as soon as possible, written reports are provided according to the schedule required by the government agency. EnCana Spill Plan Emergency Response May 2008 5 The proposed well sites are located in Garfield County, Colorado. In the Garfield County region, the Local Emergency Planning Commission (LEPC) is the County Sheriff's Office (Table 1). When notified of a spill, they may contact state and federal agencies, but be sure to confirm this, because procedures change regularly. Written reports will be compiled and submitted by EnCana.

Refer to Table 1 for current phone numbers. Garfield County Sheriff's Department (County LEPC) The Dispatch operator will assess the need for service and will dispatch emergency Police, Ambulance, Fire and/or Hazardous Material Response as required. Construction, drilling, completion and production operations personnel will contact the Garfield County Sheriff's Department in the early stages of operation to advise them of the start of operation and to provide instructions to reach the operations site. The directions will be kept on file by the Dispatch operator and utilized if required. In the event of a spill the Garfield Sheriff's department is also the County LEPC. The LEPC Coordinator will access the situation and activate the County Hazmat response team as required. The Coordinator will also act as first contact advisor to initial clean-up efforts. The Coordinator may also contact additional regulatory agencies as required, but be sure to ask them and document the response. National Response Center (NRC) The NRC must be notified in the event of a produced water spill that could reach waters of the US. The NRC will notify the US Coast Guard. They will contact the region in which the spill occurs and a regional coordinator may be dispatched to the site depending on severity of the spill. Both the EnCana's supervisor and the Garfield County LEPC Coordinator must contact the NRC. Environmental Protection Agency (EPA) The NRC should notify the EPA regarding a spill. However, contact the EPA Region 8 Spill Line (Table 1) just to be sure. Colorado Oil & Gas Conservation Commission This division must be contacted in the event of any spill (regardless of size). This is the state emergency response commission. A representative will be sent to the site if required. EnCana Spill Plan Emergency Response May 2008 8 Bureau of Land Management (BLM): Initial contact with BLM should be to the Glenwood Springs Energy Office, Grand Junction Field Office & White River field Office (Table 1). They will then activate the BLM spill response plan. EnCana Oil & Gas (USA), Inc. The EnCana Parachute, Colorado Office staff will activate EnCana's spill response personnel if required and dispatch an environmental/spill specialist to site if the spill severity requires it. The Division Manager will dispatch the Area Production Supervisor to the site to manage spill containment and clean up operations if needed. The Area Production Supervisor will communicate with the Garfield County Sheriffs Department, the appropriate surface use agency (Bureau of Land Management, Colorado Division of Wildlife) to facilitate and manage the overall clean-up operation and ensure to that all government requirements are fulfilled. EnCana Oil & Gas (USA), Inc. - Parachute, Colorado Office: The EnCana Parachute, Colorado Office staff will provide spill clean up guidance and will prepare detailed spill reports for the regulatory agencies. Environmental spill specialists will coordinate with the Garfield County LEPC Coordinator to ensure that all government regulations and requirements are met. Environmental spill specialists will work with and advise the onsite Production Supervisor regarding remediation measures required. Spill specialists will coordinate all post clean up sampling activity and reporting. EnCana Spill Plan Emergency Response May 2008 9 6.0 GENERAL SPILL RESPONSE PLAN 6.1 INITIAL COMMUNICATION AND ACTION PROCEDURES Internal spill reporting procedures require completion of an EnCana's incident/accident report as well as a spill assessment form. Information contained on this form assists operators in providing verbal reports to government authorities. The spill assessment form also helps to characterize the spill sufficiently that appropriate response procedures can be initiated. The assessment form covers spills from all facilities associated with the upstream oil and gas sector including pipelines; however the form will be completed for reportable spills only. The form is to be completed by operators at the time the spill is discovered. It is maintained with the operator's files with a copy forwarded to EnCana. The assessment form is not submitted to any government agencies. A copy of the assessment form is contained on the following page. It is important to document all phases of a spill. If an assessment form is not available, document all information (date, time of actions, phone numbers called, contact names, etc.) on available paper and transfer it to a proper form at a later date. The most critical aspects of spill response are accurately locating the spill, isolating or shutting in the source of the spill, if possible, and containing and recovering surface fluids. All of these activities must be undertaken with due consideration for the safety of the operator, clean-up crews and the general public. Reporting of the spill should take place once initial activities to contain and recover the spill are underway. Reports should be submitted to the appropriate government agencies, as well as to EnCana. The spill assessment form as well as an incident accident report form must be completed and retained in company files.

EnCana Spill Plan Emergency Response May 2008 11 6.2 SUPERVISOR'S RESPONSIBILITIES EnCana's Parachute, Colorado Office Staff can provide advice and assistance with respect to operator responsibilities as required. Operator is responsible for the following items: • Assessing the location and source of the spill and determining if the spill can be contained; • Assessing the hazards associated with responding to a spill; • Determining the extent/impact of the spill; • Contacting and dispatching clean-up crews; • Controlling access to the spill site; • Coordinating the containment and recovery of surface fluids; • Notifying company and regulatory agencies; • Completion of spill assessment form, and incident/accident report form; • Ensuring topsoil is salvaged and segregated; and • Scheduling clean-up and repairs. 6.3 "FIRST RESPONSE" COMPANIES First response companies will provide assistance with initial containment and recovery of product. Operators should be aware of local "first response" companies that they can call on to assist in initial containment of the spill. Operators should ensure that a listing of First Response companies is compiled and appended to this document. This list should also be posted in common areas at batteries and other facility sites. Operators should ensure that this list is periodically updated so that only those companies that are current appear on the list. Willow Creek Companies Russell Fowles P. O.

For smaller spills, the technique for spill clean-up is basically shoveling the material into a drum, labeling the drum, and disposing of it along with other oil field waste materials as per routine disposal methods to a landfill. Generally, Class I landfills accept this type of waste, however if the material is contained within drums, Class II landfills may also accept them. Other methods of manual recovery include using cans, buckets or rakes to pick-up contaminated soils on the surface. The important point to consider when remediating small spills is to ensure that ALL of the affected soils have been removed or otherwise dealt with and all actions to clean-up, repair the problem, and prevent further occurrence are well-documented. This is most easily accomplished if the spill is dealt with immediately, thereby not allowing the spill to soak into the ground. The following illustrates the decision matrix for spill clean-up. 7.2 REMEDIATION FOR LARGE SPILLS The information contained within this section is meant to provide guidance on initial containment, recovery and treatment measures to be applied to spills, which are "manageable" with the equipment and expertise available to the majority of EnCana's operations supervisors. This section is not meant for larger, uncontrolled spills that will require specialized equipment and expertise. EnCana Spill Plan Emergency Response 13 May 2008 Spills will require initial containment and treatment so as to minimize spill clean up and site restoration work, and the potential for environmental and public health risks. This section provides information on initial treatment to stabilize the spill and prevent the worst effects from settling in before the site can be sampled and more specific treatments applied. Contact EnCana's Parachute, Colorado Office staff for any additional advice or assistance that may be required. See contact information provided in Section 2.1. 7.2.1 SPILL CONTAINMENT Containment measures may be broadly categorized into two groups: land based and water based. The options for containment make use of a wide range of locally available materials such as straw, chicken wire, and snow fencing as well as commercial sorbents and booms. 7.2.1.1 Land Containment Methods It is important to note that land spills are generally much easier to deal with than spills that have reached a waterway. Efforts should be made to prevent or stop spilled product from entering the water. Land containment of spills can be achieved by using minor earthworks such as trenches and earth dams or dykes. In the winter, snow can be used for a similar purpose. Snow is also a suitable sorbent material for spills other than salt spills. Salt will melt the snow and result in further spread of salt contamination. Trenches Trenches can be used to intercept and hold all types of fluids; however trench construction is practical only in the summer. Figures 6.1 and 6.2 (Appendix A) provide details of an interceptor trench and methods of using trenches to intercept overland and subsurface flow. Trench construction should include the use of a plastic liner. This prevents downward migration into subsurface soils and potentially groundwater. Relatively shallow trenches may be strategically placed down slope of a spill to intercept surface and subsurface spilled materials. This method is effective in preventing subsurface contamination of water and eventual discharge to streams and other water bodies. Equipment required to build a trench includes: • Backhoe, loader, bulldozer; • Shovels, picks; and • Plastic liners. EnCana Spill Plan Emergency Response May 2008 14 Dams and Dykes Earth and snow dams may be constructed across ditches or low areas to contain a spill and stop its flow. The entire flow of the spilled material and any surface drainage may be contained. Construction materials include earth, wood, sandbags, and snow. The dam or dyke should be lined with plastic sheeting to make it impermeable to the spilled product. In the winter, water may be sprayed on the snow dams or dykes to create ice. Dams should be of sufficient size to contain the entire spill volume; insufficient capacity may result in overtopping and/or failure. 7.2.1.2 Containment on Waterways Water containment measures generally include the use of booms or barriers. However, dams and weirs may also be used for ditches with flowing water and for smaller streams. Figure 6.3 illustrates the use of dams and weirs. These methods are typically used where it is necessary to allow the water to flow, while retaining lighter than water liquids such as petroleum products that separate readily from water. Water bypass or underflow dams may also be constructed on small, slow -flowing streams. Water bypass involves first constructing an earthen dyke to stop the flow of water, and then inserting a pipe below the level of the spilled material and discharging the water on the other side of the dyke. (Figure 6.4). It is important to note that the discharge end of the pipe should not be inclined above the level of the dyke or overtopping and failure will result. Weirs made from plywood, lumber and sheet metal may also be used in ditches with flowing water and may be placed to completely or partially block culvert openings. These barriers may be suspended from stakes on either side of the culvert openings and raised or lowered to maintain the desired water level while retaining the oil. Recovery of material collected behind dams and weirs may be made with the use of sorbents, skimmers or by direct suction. Other water containment measures include the use of booms or barriers. These methods are typically limited to the containment and recovery of materials that will readily separate from and float on water. The type and size of a boom will depend on the specific location and the conditions within which the boom will be used. The general principles for using a boom are: • To contain a spill of floating liquid or debris; • To deflect or divert material to a defined area so that it may be recovered; and • To protect sensitive areas from contamination. EnCana Spill Plan Emergency Response May 2008 15 There are many common items that can be used as improvised booms. These include: • Railroad ties; • Telephone or power poles; • Trees; • Lumber; • Inflated fire hose; • Styrofoam; • Chicken wire or fishing net and sorbent materials (rolled into a sausage shape). It is important that buoyant material be used within the boom; otherwise it will become water logged and sink after several hours. Rope or wire can be used to hold the boom sections in place. Natural sorbents include straw and evergreen boughs. Commercial sorbents have greater capacity to absorb oil and other petroleum products; they last longer, and can be reused. Foam sections have good sorbent capacity and excellent buoyancy. Figures 6.5 and 6.6 illustrate methods of connecting booms together and construction of a "jellyroll" or "sausage roll" using improvised sorbent barriers. Proper boom deployment is a critical consideration. The angle of the boom relative to the flow direction must be related to water flow velocity in order to achieve effective containment (Figure 6.7). Several booms arranged in parallel may be necessary to contain the entire product. These should be spaced to allow for particles, which may escape the first boom, float to the surface, and be contained by the next boom. In addition, the use of several booms permits the removal of a boom for cleaning. Figures 6.7 to 6.9 illustrate boom deployment methods. The chart at the bottom of Figure 6.7 illustrates the proper angle to deploy the boom based on water velocity. The higher the stream velocity, the more perpendicular the boom will be with respect to the crossing. In the example shown in the illustration, proper bloom deployment is at an angle of 24° for a stream flow velocity of 175 feet/minute. Fixed barriers can be used in streams with soft beds where stakes can be driven. A snow fence barrier may be installed to span the width of a stream less than 1 m deep and may be anchored at both ends with steel or wooden stakes. Stakes are driven into the stream bottom at 3 to 6 foot intervals. Straw bales or commercial sorbents are placed on the upstream side. The barrier should be angled against the current for collection of product along the shore. Multiple snow fence barriers can be used to provide backup against potential losses from upstream barriers. Net or chicken wire barriers can be constructed for the same purpose. Figure 6.10 illustrates a typical snow fence barrier. 7.2.2 RECOVERY Recovery efforts must be undertaken as soon as it is practical and safe to do so. Focus on rapid recovery of spilled materials is required to reduce and/or eliminate any potential dangers or hazards to the environment. Recovery methods generally include suction, mechanical removal and use of sorbent materials. EnCana Spill Plan Emergency Response May 2008 16 Suction Direct suction includes the use of vacuum trucks or portable pumps. Large capacity wet service shop vacs may also be used if there is an available power source nearby. Suction screens may be required to prevent hose plugging by floating debris and to prevent pump damage. Care should be taken to reduce the uptake of water in order to minimize the amount of material, which requires disposal, and prevent mixing of oil and water. Manual and Mechanical Recovery Manual and mechanical recovery, discussed previously, is an effective option for the removal of small spills. Manual recovery using hand tools (shovels, buckets, rakes, cans) is also effective in removing spills from areas that are inaccessible to larger equipment. Though labor intensive and time consuming, manual recovery is often the only method of recovery available and in some cases is the preferred method as it causes the least amount of damage to an area. Mechanical recovery using heavy equipment is an option typically reserved for larger spills. Details with respect to the use of heavy equipment are provided in local area emergency response plans. Use ofSorbent Material Sorbents are materials that soak up oil or other product. They are commonly used for final clean up and recovery of small amounts of product or to remove product in places that are inaccessible by other means of recovery. They are effective in recovering thin as well as thick layers of product; however large volumes of sorbent material may be required for thick deposits. 7.2.3 INITIAL TREATMENT Initial treatments are designed to prevent the worst effects of a spill from "settling in" before the site can be sampled and more specific treatments completed. The purpose of initial treatment is to "buy time" to allow for more extensive sampling and analytical programs to be completed and to optimize treatment programs. Initial treatments are especially important on salt spills, as these initial remediation measures will greatly assist in deterring or slowing the soil "salinization" process. These treatments should proceed within 24 to 48 hours of the spill, before the spill dries out or receives much rain. If there has been considerable rain resulting in soft soils, chemicals may have to be hand broadcast or sprayed from offsite to prevent vehicles from rutting the soil. 7.2.3.1 Soils Handling Soil handling must be minimized to the extent possible during wet soil conditions. Typically if there is a potential to create ruts that are greater than 3 inches deep, equipment should be kept off the soils and the spill should be accessed on foot and manually dealt with as explained in Section 7.2.2. However, under an emergency situation this may not always be feasible and it may be necessary to strip the topsoil ahead of the machinery when accessing the site to prevent compaction and destruction of the soil structure. In particular, soils must be handled carefully during excavations. The following measures should be taken when excavating soils: EnCana Spill Plan Emergency Response May 2008 17 • Strip the topsoil away from the area where you intend to excavate. Stockpile the topsoil away from the area where you plan to stockpile the spoil materials to avoid mixing the two together. When it is time to fill the hole, fill it first with the spoil materials, leaving a low "roach" or mound to account for settling. Respread the topsoil evenly on top of the mound being sure to completely cover the excavated area. It is particularly important during winter excavations to not replace the topsoil until the spoil pile has settled; and • If the topsoil was contaminated during the spill, treat the topsoil according to the specifications listed below for brine and hydrocarbon spills. 7.2.3.2 Brine Spills For the purposes of this document, brine is defined as: • Water with over 10 000 mg/1 (ppm) of total dissolved solids (TDS); OR • Emulsions containing over 20% brine (emulsions with less than 20% brine can be treated as a hydrocarbon spill since the oil component will be sufficiently high that it is treatable as such); OR • Previous spills have caused "bare spots" on the ground where vegetation either does not grow, grows slowly, or is characterized by plants that appear different from the surrounding area. Information on the composition and general chemistry of fluids characterizing the field areas may be obtained from fluid sample analysis reports (CORE labs etc.), and should be reviewed by operators to determine the potential for a spill to result in impacts to soils or vegetation and the need to initiate immediate response. Initial treatment for brine spills typically involves the addition of a calcium product to be applied and incorporated into the soil within the first 24 to 48 hours of clean up prior to flushing with fresh water. Operators should be aware of product suppliers in their areas, and have a listing posted or readily available at facilities. Accepted treatment chemicals include gypsum (calcium sulphate) and various formulations of calcium nitrate (liquid or granular fertilizer 15.5-0-0; Saline Soil Saver (SSS); and LCA -II). Generally calcium nitrates are preferred because of better solubility, but are prone to surface washes and may contaminate nearby water sources. Conversely, gypsum's low solubility characteristics make it unsuitable for most sites except wet areas. Other chemicals that have been used successfully on brine spills include calcium chloride (CaC12 ), and magnesium sulphate (MgSO4 ). The following options are provided for initial remediation of brine -contaminated soils. EnCana Spill Plan Emergency Response May 2008 18 Option 1: Site Conditions: Ground is not frozen, and can be cultivated or soaked with water to incorporate the fertilizer. There are no water sources (shallow wells, sloughs, dugouts, ponds) near the spill site, and soils are average in terms of moisture levels (mesic sites). Note: Calcium nitrate should never be used in situations where site run-off could cause it to contaminate sources of drinking water for Yunnan, livestock, or wildlife consumption. Application: 2.2 lbs. calcium nitrate per 10 yards2. Procedure: Spread the fertilizer on the spill site (by hand if the soils are wet). Cultivate or water the soil well so that the fertilizer is incorporated. Soak the soil until puddles form. Let puddles soak in, and then soak the soil some more. Soak the soil as often as possible over the next few days. Calcium nitrate/polymer/flocculant formulations may also be used and are preferred when the ground is not frozen or over saturated so that the treatment soaks in immediately. These formulations are commercially available under the trade names Saline Soil Saver (SSS) and LCA -II. Application: Dilute 0.8 US gallons of SSS or 0.5 US gallons of LCA -II with 6.2 US gallons of fresh water and apply 500 US and apply to 10 square yards. Be sure to protect the concentrate from freezing. Option 2: Site Conditions: The ground is frozen and there will likely be runoff in the spring; OR the site is near water, thereby precluding the use of calcium nitrate. Application: 11 lbs. gypsum per 10 yards2. Procedure: Spread the granular gypsum on site (by hand if soils are wet). If the ground is not frozen, and cultivation of the soils is possible (the affected site is not a bog or muskeg) cultivate as soon as soils are dry enough to permit cultivation, then soak the soil until puddles form. Only soak the site once immediately prior to incorporation as the chloride salinity will aid in increasing the solubility of the gypsum. 7.2.3.3 Hydrocarbon Spills Soil contaminated by hydrocarbons must be removed from the spill site and removed to an approved landfill.
