(EnCana) received approval in November 2005 from the Bureau of Land Management (BLM) for a right-of-way grant under Section 28 of the Mineral Leasing Act of 1920, as amended, to authorize the construction, operation, and maintenance of the Meeker Pipeline and Gas Plant Project (Meeker Project). The project involves construction and operation of a natural gas processing plant and 205 miles of up to 36 -inch diameter buried natural gas, natural gas liquids (NGL) and water pipelines and related aboveground appurtenances in Garfield and Rio Blanco Counties, Colorado, and Uintah County, Utah. The Meeker -South portion of the project was originally designed to begin at EnCana's existing Logan Wash Facility and parallel Kinder Morgan's TransColorado pipeline to a termination point at the Meeker Gas Plant in Rio Blanco County, Colorado. The Meeker -South portion was rerouted and renamed to the Piceance Gathering Pipeline Project. The route now begins at EnCana's existing Roan Cliff Station and begins paralleling the original Meeker -South route co - located with Kinder Morgan's TransColorado Pipeline approximately 26 miles north of the Roan Cliff Station. 1.2 Description The Piceance Gathering Pipeline Project (project) is a portion of the Meeker Project and involves construction of approximately 49 miles of 36 -inch diameter natural gas pipeline and related aboveground appurtenances in Garfield and Rio Blanco Counties. Approximately 28 miles of the pipeline route is located in Garfield County. The Garfield County Development Plan narrative will only address the portion of the project located in Garfield County. 1.3 Purpose and Need EnCana plans to increase production in the Piceance Basin by approximately 100 to 200 million standard cubic feet per day (mscfd), each year, for the next several years. The Meeker Project will provide a natural gas gathering and processing system that will transport and process the projected future volumes of natural gas from the western slope of Colorado and the Rocky Mountain region to major interconnections with other interstate pipelines. The proposed pipelines will transport approximately 1 billion standard cubic feet per day (Bscfd) of natural gas from the Piceance Basin of westem Colorado to existing inter- and intrastate pipelines operated by Questar, Kinder Morgan, Mid -American Pipeline Company (MAPCO), Northwest, Rocky Mountain Natural Gas (RMNG), and Colorado Interstate Gas (CIG). Construction of the Piceance Gathering Pipeline will allow EnCana to transport the majority of its Piceance Basin gas to the Meeker Gas Plant for processing. This will enable EnCana to eventually remove its treatment facilities in the South Piceance area (i.e. Garfield County). The pipeline has been sized to accommodate EnCana's current and future estimated gas production from Garfield County. EnCana has designed this pipeline to accommodate existing and future natural gas from other natural gas producers in the Piceance Basin. This pipeline will transport untreated gas to a central processing facility (Meeker Gas Plant) and will provide other producers Piceance Gathering Pipeline Project 1 April 2006 Garfield County Development Plan an opportunity to transport their gas to the Meeker Gas Plant. This will allow other producers to transport their gas out of Garfield County without installing gas treatment and processing facilities. 1.4 Location The Piceance Gathering Pipeline Project (project) consists of approximately 28 miles of natural gas pipeline and related facilities. The proposed pipeline corridor begins at EnCana's existing Roan Cliff Station in Garfield County, Colorado and parallels Garfield County Road 215 in a generally south -north direction for approximately 8 miles. The corridor traverses EnCana's North Parachute Ranch property for approximately 12 miles and connects with the Kinder Morgan TransColorado pipeline corridor. The corridor follows the Kinder Morgan TransColorado corridor north to the Garfield/Rio Blanco County line. Route maps are included in Attachment 1. 1.5 Facilities 1.5.1 Project Design In Garfield County, the proposed project is approximately 28 miles of 36 -inch diameter, buried, natural gas, steel pipeline and related aboveground facilities. Facilities will include two block valves. EnCana will design and construct the pipeline in conformance with the requirements of Title 49 CFR, Part 192, "Regulations for the Transportation of Natural and Other Gas by Pipeline: Minimum Federal Safety Standards", and Part 195, "Transportation of Hazardous Materials by Pipeline". The pipeline will receive natural gas from EnCana's existing 24 -inch diameter Rifle to Logan Wash natural gas pipeline which is connected to many of the gas field in Garfield County. Compressor stations in each field will discharge gas into this new, expanded transportation system. No additional compressor stations will be constructed under this Development Plan. 1.6 Land Requirements 1.6.1 Right -of -Way The construction right-of-way width varies between 35 and 120 feet. Following construction of the pipeline, the width of the right-of-way will be reduced to a permanent right-of-way of 15 to 30 feet, depending upon the surface easement agreement. The proposed pipeline will generally be installed at the edge of existing pipeline or road right-of- ways using a 5 to 50 -foot offset from the existing pipelines. The off -set varies due to number of pipelines in the corridor, terrain and/or environmental features. Alignment sheets are included in Attachment 2. See the alignment sheets for specific information on offset distances and construction right-of-way width. 2 Piceance Gathering Pipeline Project April 2006 Garfield County Development Plan 1.6.2 Corridor Approximately 21 miles (75 percent) of the 28 -mile proposed pipeline corridor will be constructed adjacent to existing Northwest, CIG, Kinder Morgan, Questar, EnCana, or other operator pipeline corridors using the standard 5 to 50 -foot offset. Another 4 miles (14 percent) will be constructed adjacent to existing road corridors. The remaining 3 miles (11 percent) will be constructed in a newly created corridor. The newly created corridor is on lands owned by EnCana and is required to avoid sage grouse habitat. There are slight deviations in several areas to avoid topographically constrained narrow ridgetops, deeply incised washes, steep side and ascent -descent slopes, rock outcrops, and existing well pads. These areas require deviations up to several hundred feet to allow for safe, efficient construction. These areas are visible on the alignment sheets. 1.6.3 Disturbance Construction of the pipelines in Garfield County will disturb 345 acres of land. Pipeline Land Requirements in Garfield County Land Ownershi p Construction Areas (acres) Temporary Use Areas (acres) Total (acres) BLM 31.1 0 31.1 Industry 256.3 9 265.3 Private 48.1 0 48.1 Total 335.5 9 344.5 Since the construction workspace generally overlaps existing pipeline corridors, not all of the 345 acres of land used for construction will be new disturbance. In areas where the pipelines are co -located, 35 to 85 feet of the construction right-of-way will be located in areas previously disturbed. EnCana estimates that approximately 193 acres of disturbance will be in previously disturbed areas and 152 acres will be new disturbance. 1.6.4 Temporary Use Areas Additional construction right-of-way width (temporary use areas) may be required at foreign pipeline and road crossings, waterbody crossings, and steep side and ascent -descent slopes. Temporary use areas are currently identified at Davis Point, where an additional 9 acres of workspace is required due to the steep ascent -descent slope. 1.6.5 Access Roads EnCana will use existing roads to gain access to the right-of-way during construction. These access roads are primarily gravel and/or dirt roads utilized by the oil and gas industry. Garfield Piceance Gathering Pipeline Project 3 April 2006 Garfield County Development Plan CR 215 will be the primary road used for access in Garfield County. A complete list of access roads is provided in the Transportation Management Plan included in the Plan of Development. 1.6.6 Contractor/Pipe Storaae/Offloading Yards EnCana will use contractor, pipe storage, and offloading yards on a temporary basis to support construction activities. These yards have been previously disturbed, are located on privately owned land, and have been used for similar activities in the past. EnCana will utilize the existing American Soda facility for these activities. American Soda and Union Oil Company received a special use permit (99-054) from Garfield County to construct and operate the rail spur. American Soda and EnCana are finalizing an agreement that will allow EnCana to utilize a portion of the American Soda facility for a temporary construction yard. This agreement is not finalized; however, American Soda has provided a statement indicating that they have entered into negotiations with EnCana to provide a temporary construction yard. Copies of the rail spur special use permit approval, American Soda letter, and an exhibit of the temporary contractor yard are provided in Attachment 3. 1.6.7 Aboveground Appurtenances Associated aboveground appurtenances proposed by EnCana include block valves, cathodic protection equipment, and pipeline markers. Sectionalized block valves will be installed with the pipelines at locations dictated by project design and at intervals required by Department of Transportation (DOT) regulations. The perimeter of the block valve sites will be surrounded by suitable security fence. Valves will be located at milepost 4.97 and 20.97. Cathodic protection equipment will be installed as necessary along the pipeline. Exact placement and type of equipment has not yet been designed. The pipeline location will be marked with aboveground pipeline markers in accordance with DOT safety requirements. 2.0 DEVELOPMENT PLAN REQUIREMENTS 2.1 Maps and Attachments 2.1.1 Maps This Development Plan includes the following maps and exhibits: • vicinity map and route maps • individual ownership maps • full-size ownership map • alignment sheets 4 Piceance Gathering Pipeline Project April 2006 Garfield County Development Plan The alignment sheets and the vicinity map and route maps are included as attachments to this narrative. The full-size ownership map and individual ownership maps are provided as attachments to the Landowners tab. 2.1.2 Attachments This Development Plan includes the following attachments: Narrative Tab Narrative Attachment 1—Vicinity Map and Route Maps Attachment 2—Alignment Sheets Attachment 3—Construction Yard Exhibits Attachment 4— Construction March Chart Attachment 5— BLM ROW Grant Attachment 6— Garfield County Road 215 Crossing Detail Plan of Development Tab Plan of Development Attachment 1—Route Maps Attachment 2—Line List Attachment 3—BLM Fence Specifications Appendix 1—Biological Resources Protection Plan Appendix 2—Blasting Plan Appendix 3—Cultural Resources Protection Plan Appendix 4—Environmental Compliance Management Plan Appendix 5—Fire Prevention and Suppression Plan Appendix 6—Fugitive Dust Control Plan Appendix 7—Noxious Weed Management Plan Appendix 8—Paleontological Resources Protection Plan Appendix 9—Reclamation Plan Appendix 10—Safety Plan Appendix 11—Soil Conservation, Sedimentation, and Erosion Control Plan Appendix 12—Spill Prevention, Containment, and Countermeasure Plan Appendix 13—Stormwater Pollution Prevention Plan Appendix 14—Strength Testing Plan Appendix 15—Transportation Management Plan Appendix 16—Waterbody Crossing and Wetland Protection Plan Landowners Tab Attachment 1—Line List Attachment 2—Alignment Sheets Attachment 3—American Soda Surface Use Easement Agreement Attachment 4—Oldland Surface Use Easement Agreement Attachment 5—Uphoff Surface Use Easement Agreement Construction Specifications Piceance Gathering Pipeline Project 5 April 2006 Garfield County Development Plan 2.2 Construction Schedule Construction activities will begin on June 1, 2006. Construction activities are anticipated to last 6 months. With the exception of strength testing, working hours will generally be from sunrise to sunset Monday through Saturday. EnCana plans to construct this project in two portions—the Parachute Valley portion and the Piceance Creek portion. Davis Point will be the dividing point between the two portions. Estimated construction workforce is approximately 150 persons for the Parachute Valley portion and 200 persons for the Piceance Creek portion. Construction personnel will consist of EnCana employees, construction contractor employees, and construction and environmental inspection staff. The workforce will include local and non -local workers. When available, local workers will be employed for construction. Construction personnel hired from outside the project area will include construction specialists, pipeline welders, supervisory personnel, and inspectors who will temporarily locate to the area. Construction workforce personnel will be highly variable based upon construction phase. Workforce will peak during stringing and welding phases of the pipeline and taper off when stringing and welding activities are complete. Stringing and welding activities are anticipated to be at their peak in August and September; therefore, construction workforce should peak during August and September and taper off by October. A construction march chart is included in Attachment 4. The march chart depicts estimated start and end dates of each crew. Workforce numbers can be correlated to this march chart. 2.3 Construction Methods 2.3.1 Plan of Development EnCana has developed a Plan of Development, included in the Plan of Development Tab, which describes construction methods and measures to be taken by EnCana during construction, operation, and maintenance of the project. The Plan of Development establishes procedures for implementation of mitigation measures described in the Environmental Assessment and includes the following environmental compliance plans: Biological Resources Protection Plan; Blasting Plan; Cultural Resources Protection Plan; Environmental Compliance Management Plan; Fire Prevention and Suppression Plan; Fugitive Dust Control Plan; Noxious Weed Management Plan; Paleontological Resources Protection Plan; Reclamation Plan; Safety Plan; Soil Conservation, Sedimentation and Erosion Control Plan; Spill Prevention, Containment and Countermeasure Plan; Stormwater Pollution Prevention Plan; Strength Testing Plan; Transportation Management Plan; and Waterbody Crossing and Wetland Protection Plan. 2.3.2 Construction Specifications Construction of the pipeline will be in accordance with EnCana's Construction Specifications, included in the Construction Specifications Tab. 6 Piceance Gathering Pipeline Project April 2006 Garfield County Development Plan 2.3.3 Construction Sequence The following section provides a description of each phase of standard construction during the project. Staking Civil engineering surveys will be performed by EnCana to identify the centerline of the pipeline and the boundaries of both sides of the approved working limits before construction activities commence. Flagged or painted lath will be set at 200 -foot intervals (maximum), or as required to maintain line of sight, along the proposed centerline. The edges of the work limits will be marked at 200 -foot intervals (maximum), or as required to maintain line of sight, with flagged or painted lath. All temporary use areas will be marked in a similar fashion and all four corners of each temporary use area will be marked by a flagged or painted lath. Clearing, Grading, and Topsoiling Fences crossing the right-of-way will be braced, cut, and temporarily fitted with gates to permit passage. Prior to cutting or replacing the fences, EnCana will notify the grazing permittees, tenants, and landowners and give them the opportunity to be present when the fence is cut. During construction, the opening will be controlled to prevent the escape of livestock. Vegetation will be cleared and the construction right-of-way graded to provide for safe and efficient operation of construction equipment and inspection vehicles, and to provide space for the storage of subsoil and topsoil. Construction activity and ground disturbance will be limited to approved, staked areas. Trees will be cut with a chain saw and/or mechanical shears and brush will be generally cut with a hydraxe or similar equipment. Trees and brush will be cut as close to the ground as possible. Trees will be felled inside the approved right-of-way boundaries. Brush and other materials cleared from the right-of-way will typically be chipped or shredded and incorporated into the topsoil. Topsoil will generally be stripped up to a depth of 6 inches from the trenchline; however, at the landowner's request, more than 6 inches of topsoil may be salvaged and/or topsoil will be salvaged across the full -width of the right-of-way or a portion thereof. On any lands requiring grading, topsoil will be stripped from the entire portion of the right-of-way that requires grading. Up to 12 inches of topsoil will be stripped across the full -width of the right-of-way in irrigated agricultural lands. Topsoil will be stockpiled separate from subsoil and will not be used to pad the trench or construct trench breakers. Trenching Construction methods used to excavate a trench will vary depending on soils, terrain, and related factors. Trenching machines will be used where possible. In situations such as steep slopes, unstable soils, high water table, or deep or wide trench requirements, trackhoes will generally be used. Piceance Gathering Pipeline Project 7 April 2006 Garfield County Development Plan Access will be provided for landowners, tenants, and grazing permittees to move vehicles, equipment, and livestock across the trench where necessary. EnCana will contact livestock operators and provide adequate crossing facilities as needed to ensure livestock are not prevented from reaching water sources because of the open trench. The Contractor will keep wildlife and livestock trails open and passable by adding soft plugs (areas where the trench is excavated and replaced with minimal compaction) during the construction phase. Soft plugs with ramps on either side will be left at all well-defined livestock and wildlife trails and at maximum 1 -mile intervals to allow access across the trench and provide a means of escape for livestock and wildlife that may fall into the trench. A typical trench will be excavated approximately 48- to 60 -inches wide at the bottom and the sides will be sloped to Occupational Safety and Health Administration (OSHA) specifications. The depth of the ditch will be approximately 80- to 110 -inches deep. The depth and width of the ditch will vary depending upon soil types. The cover from top of pipe to ground level as graded to finished right-of-way will be in conformance with DOT regulations. Greater depths of cover will be required at unpaved road crossings, foreign pipeline crossings, waterbodies, and other obstructions. Excavated subsoil will be stored separate from windrowed topsoil piles. Subsoil will not be stored in flowing waterbodies and dry drainages or washes that cross the right-of-way will not be blocked with subsoil. Subsoil will be placed on the banks of the drainage. Gaps will be left periodically in the subsoil piles to avoid ponding and excess diversion of natural runoff during stone events. Pipe Installation Pipe installation will include stringing, bending for horizontal or vertical angles in the alignment, welding the pipe segments together, inspection, coating the joint areas to prevent corrosion, and then lowering -in and padding as described in greater detail below. Stringing Line pipe will be shipped directly from the manufacturer by rail to pipe yards and then hauled by stringing trucks to the pipeline right-of-way. Each individual joint of pipe will be unloaded with a sideboom or trackhoe fitted with a vacuum device and placed (strung) parallel to the ditch in a continuous line. Sufficient pipe for road or waterbody crossings will be stockpiled at staging areas near the crossings. Stringing operations will be coordinated with trenching and installation activities in order to properly manage the construction time at a particular tract of land. Gaps will be left at access points across the ditch to allow crossing of the right-of-way. Bending After joints of pipe are strung along the ditch but before the joints are welded together, individual joints of pipe will be bent to accommodate horizontal and vertical changes in direction. A hydraulically operated bending machine will be used to create field bends. Where the deflection of a bend exceeds the allowable limits for a field -bent pipe, factory (induction) bends or segmented joints will be installed. 8 Piceance Gathering Pipeline Project April 2006 Garfield County Development Plan We/ding After pipe joints are bent, the pipe joints will be lined up end-to-end and clamped into position. The natural gas pipelines will be welded in conformance with 49 CFR Part 192, Subpart E. "Welding of Steel Pipelines" and API 1104, "Standard for Welding Pipelines and Related Facilities," latest edition approved by DOT. Inspection All welds will be visually inspected by a qualified inspector. Non-destructive radiographic inspection methods will be conducted in accordance with DOT requirements. A specialized contractor will be employed to perform this work. Any defects will be repaired or cut out as required under the specified regulations and standards. 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 a tape wrap, shrinkable sleeve wrap, or field -applied fusion bond epoxy. 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 (holidays) will be repaired. Lowering -in and Padding Before the pipe section is lowered into the ditch, inspection will be conducted to verify that the pipe is properly fitted and installed into the ditch, minimum cover is provided, and the trench bottom is free of rocks and other debris that could damage the external pipe coating. Dewatering may be necessary where water has accumulated in the trench, and will occur in accordance with EnCana's Soil Conservation, Sedimentation, and Erosion Plan included in the Plan of Development. Side -boom tractors will be used to simultaneously lift the pipe section, position it over the ditch, and lower it in place. Padding machines will be used to sift soil fines from the excavated subsoils to provide rock -free pipeline padding and bedding. Sandbags may be used to pad the bottom of the ditch instead of, or in combination with, padding with soil fines. In rocky areas, padding material or a rock shield will be used to protect the pipe. No topsoil will be used to pad the pipe. Backfilling Backfilling will begin after a section of pipe has been successfully placed in the ditch. Backfill will be conducted using a bulldozer, rotary auger backfiller, padding machine, or other suitable equipment. Backfillingthe trench will generally use the subsoil previously excavated from the trench, except in rocky areas where imported select fill material maybe needed. Backfill will be graded and compacted, where necessary for ground stability, by tamping or walking with a wheeled or tracked vehicle. Compaction will be performed to the extent that there are no voids in the trench. Backfill of trenches will not be performed where the soil is frozen to the extent that large consolidated masses are formed that will not break down. In irrigated agricultural areas, the backfill will be replaced at the same compaction density as the adjacent undisturbed soil. Any excavated materials or materials unfit for backfill will either be utilized elsewhere or properly disposed of in conformance with applicable laws or regulations. Piceance Gathering Pipeline Project 9 April 2006 Garfield County Development Plan Cleanup and Restoration Cleanup and restoration will occur after the pipeline is installed, and will begin after backfill activities are completed. Cleanup of the surface along the right-of-way and any temporary use areas will be performed by removing any construction debris and by performing final grading to the finished contour. Erosion control measures will be installed as described in EnCana's Soil Conservation, Sedimentation, and Erosion Control Plan. Restoration seeding will be performed in accordance with fee -landowner and BLM requirements as described in EnCana's Reclamation Plan. The Soil Conservation, Sedimentation, and Erosion Control Plan are included in the Plan of Development. 2.4 Required Permits The following table lists permits required to construct the project: Required Permits Agency Permit or Consultation Applicability Federal Department of Interior Bureau of Land Management—Lead Agency—White River Field Office Right -of -Way Grant Pipeline Right -of -Way Grant Department of Defense Sacramento District Army Corps of Engineers—Grand Junction, Colorado NWP 12 Pre -Construction Notification Work in navigable waters of United States (U.S.); or discharge dredge, or fill material in waters of U.S., including wetlands State of Colorado Department of Public Health and Environment Air Pollution Control Division Construction Emissions Permit Department of Public Health and Environment Water Quality Control Division Construction Stormwater Permit Minimal Industry Discharge Permit Construction of land development projects greater than 25 acres Discharge of stormwater from construction site Discharge of hydrostatic test water and discharge of groundwater from construction site Local -Colorado Garfield County Development Plan Road Crossing Permit Installation of pipelines Crossing of County roads and rights-of-way EnCana has received the BLM ROW Grant, which is included as Attachment 5.

EnCana has identified areas of concern that include nesting raptors, Greater sage grouse habitat, and paleontological resources. In Garfield County, nesting raptors were identified at mileposts 11.8, 12.6, 13.1, and 20.4; Greater sage grouse habitat has been identified between mileposts 8.0 and 24.0; and bedrock formations potentially containing paleontological resources are present between mileposts 22.0 and 24.0. Survey results are based on 2005 surveys. EnCana will resurvey the entire route for noxious weeds, nesting raptors, and Greater sage grouse prior to construction activities. If survey results differ from 2005, EnCana will submit the new information to the County. EnCana consulted with the BLM, Colorado Division of Wildlife (CDOW), and the U.S, Fish and Wildlife Service to identify wildlife species of concem. Field surveys were conducted to determine the presence or absence of suitable habitat for species of concern. The project will not affect any federally listed threatened or endangered species. Impacts to raptor and Greater sage grouse populations and habitats have been mitigated in accordance with BLM and CDOW consultations. EnCana will comply with the following Greater sage grouse protection measures: • Conduct sage grouse presence surveys, habitat assessment, and review of historical lek sites prior to 2006 construction activities. BLM-approved biologists will be required to meet with BLM biologists prior to initiating surveys, and will conduct the surveys using BLM survey protocols. • Avoid surface disturbing activities between March 15t and May 31st in sage grouse lek areas, April 15`h and July 7th in sage grouse production areas, and December 16t and March 15th in winter range. Leks and production areas are present between mileposts 8.0 and 27.3 and Piceance Gathering Pipeline Project 13 April 2006 Garfield County Development Plan winter range is present between mileposts 8.0 and 23.0. Timing restrictions may be adjusted based on results of spring 2006 pre -construction surveys. • Seed disturbed areas with a seed mix designed to reestablish sagebrush and forb species. Sagebrush used for reseeding will be collected from local species. Distribution of sagebrush will be dependent upon range site (i.e., Artemesia tridentata spp. vaseyana and spp. wyomingensis). Reclamation on these sites will use seed mixes and seeding methods that include and promote successful establishment of full complement of grasses and favored native forbs. The following forbs will be included in reclamation seed mixes as appropriate throughout sage grouse range on lands administered by the BLM and lands under EnCana's control or lease: 1) scarlet globemallow, 2) Utah sweetvetch, 3) arrowleaf balsamroot, 4) Lewis flax, and 5) Rocky Mountain penstemon. Seed mixes are provided in the Reclamation Plan. • Additional vegetation clearing to enhance sage grouse habitat will be negotiated between the BLM and the CDOW. If habitat along the existing right-of-way and the surrounding area is determined to be unsuitable due to advanced vegetation succession (e.g., pinyon -juniper regeneration, encroaching serviceberry, etc.), expansion of vegetation removal will be applied along the right-of-way to reclaim a larger area of suitable cover for sage grouse. Where possible, the proposed right-of-way will be shifted to maximize clearing of encroaching vegetation. These areas will be identified during pre -construction sage grouse habitat surveys. • Establish and maintain permanent enclosures on each of the mid- and high -elevation sage grouse habitat intervals. Enclosures will be established as a means of determining the ultimate success of forbs in the reclamation seed mix and will be designed to exclude cattle and wild horses, with dimensions of 100 feet paralleling the right-of-way and a width that spans the fully authorized temporary construction right-of-way. The location of these structures will be subject to approval of the BLM Authorized Officer. The general location on BLM lands is milepost 23.0 and 24.0 (mid -elevation sage grouse habitat). The BLM requests that, in the interest of sage grouse conservation, EnCana arrange to establish a similar enclosure on private lands in the high elevation segment south of milepost 22.0. EnCana will comply with the following raptor protection measures: • Conduct spring 2006 pre -construction nesting raptor surveys prior to construction. BLM- approved biologists will be required to meet with BLM biologists prior to initiating surveys and will conduct the surveys using BLM survey protocols. Surveys will be conducted in suitable nesting habitat (mature pinyon juniper woodland) for all accipiter species. In areas where the proposed pipeline corridor parallels existing disturbance, surveys will be conducted 300 feet from the edge of the right-of-way. In areas where the proposed right-of-way does not parallel an existing disturbance (i.e., a deviation), surveys will be conducted within 2,000 feet from the edge of the right-of-way for the portion of pinyon -juniper habitat being dislocated from the stand by the pipeline corridor and 300 feet from the edge of the right-of-way for the stand portion of the 14 Piceance Gathering Pipeline Project April 2006 Garfield County Development Plan habitat. Surveys will be completed when the birds are either on eggs or when chicks are present. Construction activities will be prohibited within 0.25 -miles of active nests between February 1st and August 15th or until fledging and dispersal of the young. Spring 2005 surveys identified active nests in Garfield County at mileposts 11.8, 12.6, 13.1, and 20.4. - Surveys will be conducted in suitable nesting habitats within 1 -mile of the proposed project for cliff nesting species. Construction activities will be prohibited within 0.25 - miles of active nests between February 1St and August 15th or until fledging and dispersal of the young. EnCana consulted with the BLM and conducted paleontolgical surveys in accordance with BLM protocols. EnCana will comply with the following paleontological protection measures: • Paleontological Monitors will spot-check construction activities through Condition II formations. Paleontological monitoring in Condition II areas will involve periodically spot-checking the trench prior to backfill activities. Detailed information on results of surveys; timing limitations and buffer zones, and mitigation measures are provided in the Biological Resources Protection Plan, Cultural Resources Protection Plan, Noxious Weed Management Plan, and Paleontological Resources Protection Plan included in the Plan of Development. 2.8 Revegetation Plan EnCana's Reclamation Plan is included in the Plan of Development. This plan describes prescribed methods for topsoil replacement, reseeding, and monitoring for reclamation success. The plan includes seed mixes and rates, seeding schedule and methods, and mulch application. EnCana will implement the following mitigation measures during cleanup and restoration activities: • Restore pre -construction contours and drainage patterns. • Decompact subsoil to a depth of 6 to 10 inches prior to topsoil replacement. Decompact topsoil as necessary in areas where topsoil was not salvaged. • Return topsoil to pre -construction depths and locations. • Remove rocks larger than four inches in any dimension from the restored topsoil in all irrigated agricultural areas. In all other areas, remove rocks to match approximate pre - construction conditions. Excess rock may be randomly distributed across the right-of-way to block use of the right-of-way by motor vehicles in selected areas. Any rocks removed from the right-of-way will be disposed of in an approved disposal site. EnCana will coordinate with landowners and the BLM regarding the methods of disposal. Piceance Gathering Pipeline Project 15 April 2006 Garfield County Development Plan • Use vegetative mulch and excess rock to reduce erosion potential by providing additional surface relief structure. - Distribute vegetative debris salvaged during clearing and grading operations across the right-of-way, as discussed below. - Layer rock on the surface of erodible soils in critical areas to reduce erosion and restore appearance of native surface. - Apply mulch on slopes 30 percent or steeper. - Install erosion control matting on slopes 40 percent or steeper. • Seed disturbed areas with the goals of replacing suitable wildlife habitat and browse and providing a vegetative cover that stabilizes soils to control erosion and sedimentation. Typical seed mixes will reflect environmental conditions and ecological range sites along the project route and emphasize the use of native species. Seed mixes, rates, and application areas are provided in the Reclamation Plan. • Use certified weed -free seed purchased from and blended by qualified producers and dealers. • Employ drill or broadcast seed methods to ensure proper seed placement. Drill seeding is preferred and will be used wherever soil characteristics and slope allow effective operation of a rangeland seed drill. Drill seeding will be performed perpendicular to the slope. Seed will be placed in direct contact with the soil at an average depth of 0.5 -inches, covered with soil, and firmed to eliminate air pockets around the seeds. Broadcast seeding will be employed only in areas where drill seeding is unsafe or physically impossible. Seed will be applied uniformly over disturbed areas with manually operated cyclone -bucket spreaders, mechanical spreaders, or blowers. Broadcast application rates will be twice that of drill rates. The seed will be uniformly raked, chained, dragged, or cultipacked to incorporate seed to a sufficient seeding depth. • Complete drill and/or broadcast seeding prior to redistribution of woody material. • Redistribute large, woody material salvaged during clearing operations on BLM lands. Disperse materials over the portion of the right-of-way from which the trees and brush were originally removed to meet fire management objectives and to provide wildlife habitat, seedling protection and a deterrent to vehicular traffic. Woody materials dispersed across the right-of-way will not exceed 3 to 5 tons/acre. • Install erosion control measures in accordance with the Soil Conservation, Sedimentation, and Erosion Control Plan included in the Plan of Development. • Repair all irrigation ditches, cattle guards, fences, and artificial and natural livestock and wildlife water sources to at least pre -construction conditions. 16 Piceance Gathering Pipeline Project April 2006 Garfield County Development Plan • Establish and maintain permanent enclosures on each of the mid- and high -elevation sage grouse habitat intervals. Enclosures will be established as a means of determining the ultimate success of forbs in the reclamation seed mix and will be designed to exclude cattle and wild horses, with dimensions of 100 feet paralleling the right-of-way and a width that spans the fully authorized temporary construction right-of-way. The location of these structures will be subject to approval of the BLM Authorized Officer. The general location on BLM lands is milepost 23.0 and 24.0 (mid -elevation sage grouse habitat). The BLM requests that, in the interest of sage grouse conservation, EnCana arrange to establish a similar enclosure on private lands in the high elevation segment south of milepost 22.0. 2.9 Weed Management Plan EnCana is committed to preventing the introduction of noxious weeds during construction and controlling the expansion of existing noxious weed populations over the life of the project. EnCana's Noxious Weed Management Plan, included in the Plan of Development, prescribes methods to treat existing weed infestations, prevent introduction and spread of infestations during construction, and monitor and treat infestations after construction is complete. EnCana will implement the following measures to minimize noxious weed impacts: • Conduct spring 2006 pre -construction field surveys prior to construction to identify existing noxious weed infestations within the project area. • Consult with BLM and the County to determine pre-treatment for noxious weed infestations identified during spring surveys. • Require vehicles and equipment to arrive at the work site clean, power -washed, and free of soil and vegetative debris capable of transporting weed seeds or other propagules. • Install wash stations at designated infestation areas. Equipment will be power -washed to remove soil and propagules prior to leaving the infested areas. Wash station locations will be determined in conjunction with the BLM and the County after spring surveys have been completed. • Use certified weed -free erosion control and reclamation materials (i.e., straw bales and seed mixes). • Monitor the distribution and density of noxious weeds on the right-of-way for the life of the pipeline and control and/or eradicate any new or expanded population for the life of the project. • Seed disturbed areas with approved BLM and landowner seed mixes. Piceance Gathering Pipeline Project 17 April 2006 Garfield County Development Plan 2.10 Emergency Response Plan EnCana will comply with its Emergency Response Plan (ERP), which describes the functional roles and accountabilities for life safety, property damage, and environmental response. The ERP also describes the communication and notification protocols to engage support, based on the nature and complexity of the emergency. The ERP is attached to the Safety Plan in the Plan of Development. Detailed safety measures and notification protocols are presented in EnCana's Fire Prevention and Suppression Plan, Spill Prevention, Containment, Countermeasure Plan, Strength Testing Plan, and Safety Plan. These plans are included in the Plan of Development. EnCana will reimburse the appropriate emergency service provider for costs incurred in connection with emergency response for activities associated with this project. 211 Traffic Impact Interstate Highway 70 is the major east -west arterial and Colorado State Highway 13 is the major north -south arterial within the project area. In Garfield County, the majority of the project will be accessed from Garfield CR 215. From Garfield CR 215, access will be via EnCana's North Parachute Ranch Road and Middle Fork Access Road and Exxon's Colony Road across Exxon property. Several unsurfaced roads from Garfield CR 215 will also be used to access the pipeline. Secondary access to the northem portion of the project area located in Garfield County will be from Cow Creek and Sprague Gulch Roads via Rio Blanco CR 5. Construction of the Parachute Valley portion of the pipeline will result in an estimated 75 additional commuter roundtrips per day from communities in the region and will have the most impact on Garfield CR 215. The 75 commuter trips will be from I-70 to the temporary construction yard located at the existing American Soda facility. The following table depicts estimated traffic numbers from the construction yard north along Garfield CR 215 to EnCana's North Parachute Ranch: Traffic Impacts Vehicle Type and Number Roundtrips (yard to EnCana NPR) Buses -4 1 Pick-up Trucks -40 1 Lowboys -2 3 Grease truck -1 3 Fuel Truck -1 3 Winch Truck -1 10 Stringing Trucks -3 10 Traffic impact is highly variable based upon construction phase. Traffic will peak during stringing and welding phases of the pipeline and taper off when stringing and welding activities are complete. 18 Piceance Gathering Pipeline Project April 2006 Garfield County Development Plan Construction of the project will require pipeline installation adjacent to and across Garfield CR 215. EnCana will acquire and adhere to permits required by Garfield County for utility installation within the right-of-way. A site-specific crossing detail is provided in Attachment 6. EnCana will implement the following measures to minimize impacts to transportation and roads: • Begin and end construction activities after the average workday, as practical, to minimize traffic congestion impacts to the public. • Use the construction yards as the primary parking area for personal vehicles. Transport the majority of pipeline construction workers to the construction right-of-way by buses provided by the contractor, as practical. • Install the pipeline across Garfield CR 215 in accordance with Garfield County road crossing permits. • Comply with county and state weight restrictions and limitations. • Acquire overweight and oversize permits prior to construction. • Control dust along unsurfaced access roads and minimize tracking of soil onto paved roads, as discussed in the Fugitive Dust Control Plan included in the Plan of Development. • Maintain unsurfaced roads during construction of the project. • Restore roads to equal or better condition than pre -construction levels after construction is complete. 2.12 Staging Areas/Construction Yard EnCana will use contractor, pipe storage, and offloading yards on a temporary basis to support construction activities. These yards have been previously disturbed, are located on privately owned land, and have been used for similar activities in the past. EnCana will utilize the existing American Soda facility for these activities. American Soda and Union Oil Company received a special use permit (99-054) from Garfield County to construct and operate the rail spur. American Soda and EnCana are finalizing an agreement that will allow EnCana to utilize a portion of the American Soda facility for a temporary construction yard. This agreement is not finalized; however, American Soda has provided a statement indicating that they have entered into negotiations with EnCana to provide a temporary construction yard. Copies of the rail spur special use permit approval, American Soda letter, and an exhibit of the temporary contractor yard are provided in Attachment 3. During construction of the pipeline, portable toilets will be available on-site and potable water will be transported from off-site and made available to construction personnel. Electricity and telephone lines will be installed at the temporary construction offices. Piceance Gathering Pipeline Project 19 April 2006 Garfield County Development Plan 2.13 Hydrotest Water The amount of hydrostatic test water for the 28 -mile Garfield County portion has not yet been determined; however, approximately 12.7 million gallons of water will be required to test the entire project. Water will be obtained from a combination of sources, with the majority of water used in Garfield County acquired from the Colorado River. Water used in the project area in the northern portion of Garfield County will be acquired from Piceance Creek or the White River. EnCana will utilize its water rights on Piceance Creek and purchase supplemental water from the Colorado and White Rivers. When surface water sources are used, EnCana will use screens on the intake hoses to prevent the entrapment of fish or other aquatic species. EnCana will monitor the appropriation rate to ensure that an adequate downstream flow is maintained to support aquatic Life. Hydrostatic test water discharge will be returned to surface waters. Potential discharge locations are Middle Fork of Parachute Creek and the West Fork of Parachute Creek. These discharge locations are located at mileposts 5.5 and between mileposts 14.8 and 18.0. EnCana will implement the following mitigation measures to minimize impacts with hydrostatic testing: • Withdraw and discharge hydrostatic test water in accordance with the CDPHE WQCD MINDI permit. • Test water quality during withdrawal and discharge in accordance with permit stipulations and conditions. • Utilize screens on the intake hoses at surface water sources to prevent the entrapment of fish or other aquatic species and monitor the appropriation rate to ensure that adequate downstream flow is maintained to support aquatic life. • Install energy -dissipating devices (straw bale structure) to prevent scour, erosion, and damage to vegetation and monitor the rate of discharge to ensure effectiveness of the energy - dissipating device. Additional information on hydrostatic testing activities is provided in the Strength Testing Plan included in the Plan of Development. 3.0 DEVELOPMENT PLAN REVIEW STANDARDS 3.1 Right -of -Way Location The pipeline route has been routed adjacent to existing pipeline and road corridors for 89 percent of the route. The existing pipeline corridor is not typically located along the perimeters of the surface property ownerships. In the Parachute Valley, the pipeline corridor is located adjacent to County Road 215 and is located along the perimeters of agricultural areas. 20 Piceance Gathering Pipeline Project April 2006 Garfield County Development Plan 3.2 Noise Project -related vehicle traffic and heavy equipment operation will generate noise during construction of the pipeline and noise levels will increase near the project area during construction activities. Impacts from construction activities will be localized and temporary. Operation of the pipeline, block valves, and meter station will not result in any noise impacts. All equipment used during construction of the pipeline will meet with the Colorado Oil and Gas Conservation Commission Rules and Regulations, Section 802, Noise Abatement. Construction - related noise will be minimized by muffling all vehicles and construction equipment and limiting construction activities to daylight hours as much as possible to avoid impacts to the public. 3.3 Visual Impacts Construction and operation of the pipeline will not permanently affect any viewscape. Construction of the pipeline will cause visual impacts from removal of existing vegetation and the degree of the impact will depend on the type of vegetation affected. In grasslands, meadows, and cultivated agricultural lands, the visual impacts will be hardly noticeable once vegetation has returned to its original state. Areas cleared of forested vegetation will cause the most impact, and visual impacts will persist for years. In areas where the pipeline corridor parallels an exiting pipeline or road corridor (89 percent of the route), the visual impacts will be an incremental increase to those already existing and the new corridor will leave similar line, color, and texture contrast. Viewscape impacts caused by pipeline construction will be minimized by implementing measures proposed in EnCana's Reclamation Plan included in the Plan of Development. EnCana will: • Restore the right-of-way to as near as possible original contours and restore natural drainage and runoff patterns. • Scatter salvaged vegetative debris randomly across the right-of-way. • Restore the appearance of naturally rocky slopes and areas that have a natural gravel, cobble, or boulder veneer on the surface by layering or scattering rock across the right-of-way. • Seed disturbed areas with approved BLM and landowner seed mixes. 3.4 Access Roads EnCana will utilize existing access points to public roads. No new roads will be constructed as part of this project. EnCana will implement the following measures to minimize impacts to transportation and roads: • Begin and end construction activities after the average workday, as practical, to minimize traffic congestion impacts to the public. Piceance Gathering Pipeline Project 21 April 2006 Garfield County Development Plan • Use the construction yards as the primary parking area for personal vehicles. Transport the majority of pipeline construction workers to the construction right-of-way by buses provided by the contractor, as practical. • Install pipelines across county roads in accordance with County road crossing permits. • Comply with county and state weight restrictions and limitations. • Acquire oversize and overweight vehicle permits prior to construction. • Control dust along unsurfaced access roads and minimize tracking of soil onto paved roads, as discussed in the Fugitive Dust Control Plan included in the Plan of Development. • Maintain unsurfaced roads during construction of the project. • Restore roads to equal or better condition than pre -construction levels after construction is complete. EnCana will schedule an on-site visit with the County Road and Bridge Director to discuss this project. 3.5 Endangered Species This project will not threaten any endangered species. Please refer to Section 2.7 3.6 Air Emissions Air quality will temporarily decrease during construction of the pipeline due to construction emissions that will include vehicle exhaust and fugitive dust. Construction activities will take place mainly during the hours of 7:00 a.m. and 7:00 p.m. each day for approximately 6 months, after which they will cease. Exhaust emissions will increase from the operation of construction vehicles and equipment. Fugitive dust will increase and the intensity of impacts will be dependent on the level of construction activity and the soil composition and dryness. Fugitive dust will increase from vehicular traffic on unpaved roads and during grading, trenching, padding, backfilling, and reclamation activities. Actual concentrations of vehicle exhaust and fugitive dust in the air cannot be easily estimated because construction is a linear process in which equipment does not stay at one location for an extended period as the project progresses. Wind dispersion and dilution will reduce the impacts from emissions and these impacts will be localized to the construction right-of-way and access roads during the construction phase of the project. Air quality impacts from construction activities will be temporary until stabilization and revegetation of disturbed areas is complete. Operation of the pipeline will not result in any impacts to air quality. EnCana will implement the following measures to minimize impacts to air quality during construction: • Adhere to CDPHE APCD Construction Emissions permit stipulations. 22 Piceance Gathering Pipeline Project April 2006 Garfield County Development Plan • Maintain and tune equipment to manufacturers' specifications. • Transport the majority of workers from contractor yards to the construction site in buses provided by the contractor. • Limit opacity of fugitive dust to 20 percent or less. • Apply water and/or an approved dust suppressant on non -paved roads and construction work areas. • Clean soil tracked onto paved roads more than 50 feet from the point of origin within one hour of discovery and clean soil tracked less than 50 feet from the point of origin by the end of the working day. • Cease construction operations when wind speeds exceed 30 miles per hour (mph). • Limit vehicle speed to 15 mph on the right-of-way and to the posted speed limits on unpaved roads. • Seed disturbed areas with approved BLM and landowner seed mixes. Additional information is provided in the Fugitive Dust Control Plan in the Plan of Development. 3.7 CDPHE Water Quality Control Standards Construction and operation of the pipeline will comply with all county, state, and federal water quality standards, including those regulating erosion and sedimentation, storm drainage and runoff control, solid wastes, and hazardous substances. EnCana will comply with the COE NWP 12, CDPHE WQCD MINDI, and CDPHE WQCD Stormwater permit conditions. Impacts to surface water quality will be minimized by implementing measures proposed in EnCana's Stormwater Management Plan, Soil Erosion and Sedimentation Control Plan, Waterbody Crossing and Wetland Protection Plan, and Strength Testing Plan in the Plan of Development. EnCana will: • Install temporary equipment bridges across flowing waterbodies. • Place topsoil and spoil at least 10 feet away from the waters edge. • Complete the crossing within 24 hours, as feasible. • Install erosion and sediment control measures to prevent the flow of spoil into any waterbodies. Piceance Gathering Pipeline Project 23 April 2006 Garfield County Development Plan • Maintain erosion and sediment control measures until streambanks and adjacent upland areas are stabilized. • Reestablish pre -construction bed and bank contours, revegetate streambanks, and install erosion control fabric to stabilize the streambanks. • Direct trench dewatering discharges onto a well -vegetated, stable surface and utilize a section of geotextile fabric or plywood to prevent scouring during discharge. • Locate trench dewatering discharges as far as practicable from waterbodies (considering local topography, vegetation, and soils). • Minimize duration of trench dewatering discharges by scheduling dewatering operations immediately prior to lowering in, tie-ins, or backfilling. Minimize trench disturbance (i.e. additional digging) to the extent practicable until the majority of the water is pumped out. • Prohibit storage of hazardous materials, chemicals, fuels, lubricating oils, and concrete coating and refueling .activities within 200 feet of any waterbody. • Minimize erosion from upland areas by seeding the project area with approved BLM and landowner seed mixes. • Withdraw and discharge hydrostatic test water in accordance with all applicable permits. • Test water quality during withdrawal and discharge in accordance with permit stipulations and conditions. • Utilize screens on the intake hoses at surface water sources to prevent the entrapment of fish or other aquatic species and monitor the appropriation rate to ensure that adequate downstream flow is maintained to support aquatic life. • Install energy -dissipating devices (straw bale structure) to prevent scour, erosion, and damage to vegetation and monitor the rate of discharge to ensure effectiveness of the energy - dissipating device. 3.8 County Individual Sewage Disposal Regulations The project will not require any waste disposal or treatment facilities. Portable toilets will be provided on-site. Contents will be removed and disposed of in accordance with applicable laws and regulations. 3.9 Reclamation Plan Please refer to the discussion on reclamation in Section 2.8. 24 Piceance Gathering Pipeline Project April 2006 Garfield County Development Plan 3.10 Abandonment Prior to abandonment of the pipeline, EnCana will contact the Garfield County Planning Director to arrange for a meeting and joint inspection of the right-of-way. This meeting and inspection will take place a minimum of 30 days prior to abandonment, and will be held so that an agreement on an acceptable abandonment plan can be reached. This plan will include, but not be limited to, abandonment and/or removal of facilities, drainage structures and/or surface material, recontouring, replacing of topsoil, seeding, and monitoring. Should the abandoned pipeline be removed, it will be subject to all revegetation and weed management requirements listed in this narrative and supporting documents. 4.0 ADDITIONAL CONCERNS 4.1 Socioeconomics The construction workforce is expected to be 150 persons in the Parachute Valley portion of the project and 200 persons in the Piceance Creek portion of the project, for an estimated total of 350 construction personnel. Given the brief six month construction period, most non -local workers are not expected to be accompanied by their families. Non -local workers will require temporary housing in communities adjacent to the project area. Temporary housing is available in the form of daily, weekly, and monthly rentals in motels, hotels, recreational vehicle (RV) parks, and rental houses. Construction of the pipeline will result in a temporary increase of populations in communities within commuting distance of the project. Demand for temporary housing will rise. Housing will be available, but may be more difficult to find and/or expensive to secure. Construction workers may have to drive longer distances to locate accommodations. Other demands on local agencies will include increased enforcement activities associated with issuing permits for vehicle load and width limits, emergency medical services to treat injuries resulting from construction activities, and law enforcement services to respond to traffic violations and accidents. Local businesses, including gas stations, laundromats, restaurants, liquor stores, and grocery stores will see an increase in revenue. Cities and counties will see an increase in sales tax revenue due to increased purchases by the construction workforce. EnCana will implement the following measures to minimize impacts on local services: • Begin and end construction activities after the average workday, as practical, to minimize traffic congestion impacts to the public. • Implement a health and safety program that will include training on-site supervisory personnel in First Aid and cardiopulmonary resuscitation (CPR). • Provide security measures and/or personnel to patrol EnCana facilities. • Implement a fire prevention and control program as discussed in the Fire Prevention and Control Plan in the Plan of Development. Piceance Gathering Pipeline Project 25 April 2006 Garfield County Development Plan • Provide transportation for pipeline construction workers to the construction right-of-way by buses provided by the contractor, as practical. • Enter project discussions with Garfield County to determine appropriate mitigation measures, as necessary. 4.2 Waterbody Crossings The pipeline corridor will cross 3 perennial and 40 intermittent drainages in Garfield County. With the exception of the East Fork of Parachute Creek and one crossing of the Middle Fork of Parachute Creek, all waterbodies are expected to be dry at the time of construction. EnCana plans to open -cut all waterbody crossings. Sedimentation and turbidity impacts will be caused by in -stream construction. Sedimentation and turbidity impacts associated with in -stream construction will be temporary and limited to the duration of in -stream construction (typically less than 24 hours). The greatest sediment load will occur immediately downstream of the crossing, and suspended sediment concentration will progressively decrease downstream as the large sediment particles deposit on the channel bed. The open -cut crossing method will involve trenching through the waterbody while water continues to flow across the trench. Trackhoes will excavate a trench in the flowing waterbody from one or both of the waterbody banks. Equipment operating within the waterbody will be limited to that needed to construct the crossing. EnCana will place spoil excavated from the trench a minimum of 10 feet from the edge of the waterbody for temporary storage. Sediment barriers will be installed where necessary to prevent sediment and excavated spoil from entering the water. Earthen trench plugs will be left in place on both banks of the waterbody until immediately before pipe installation in order to separate the waterbody trench from the upland trench to prevent water from being diverted into the upland portions of the pipeline trench and to keep muddy water that accumulates in the upland trench from flowing into the waterbody. Once the trench is excavated, the prefabricated segment of pipe will be installed in the trench at least 5 feet under the streambed. The trench will then be backfilled with native streambed spoil and the streambanks restored to pre -construction contours. EnCana will implement the following mitigation measures to minimize water quality impacts during waterbody crossings: • Install temporary equipment bridges across flowing waterbodies. • Place topsoil and spoil at least 10 feet away from the waters edge. • Bury the pipeline at least 5 feet below the bottom of each drainage. • Cross streams during periods of low flow and complete the crossing within 24 hours, as feasible. • Install erosion and sediment control measures to prevent the flow of spoil into any waterbodies. 26 Piceance Gathering Pipeline Project April 2006 Garfield County Development Plan • Maintain erosion and sediment control measures until streambanks and adjacent upland areas are stabilized. • Reestablish pre -construction bed and bank contours, revegetate streambanks, and install erosion control fabric to stabilize the streambanks. • Prohibit storage of hazardous materials, chemicals, fuels, lubricating oils, and concrete coating and refueling activities within 200 feet of any waterbody. In the event that open -cut crossings are prohibited by Garfield County, EnCana will cross flowing waterbodies using a dry -trench method. Dry -trench methods include fluming or damming and pumping. Both methods utilize a sand bag and plastic sheeting diversion structure (or equivalent) to temporarily dam waterbody flow. The flume method requires installation of a flume pipe to divert waterbody flow across the trench. The dam and pump method utilize pumps and hoses to divert waterbody flow across the trench. Additional waterbody crossing information is provided in the Waterbody Crossing and Wetland Protection Plan in the Plan of Development. 4.3 Stormwater Management Stormwater best management practices (BMPs) are detailed in EnCana's Stormwater Pollution Prevention Plan and Soil Conservation, Sedimentation, and Erosion Control Plan in the Plan of Development. EnCana will implement the following measures to control stormwater runoff: • Install temporary erosion and sediment control devices immediately after initial soil disturbance and will be maintained throughout construction and restoration, as necessary, until replaced by permanent erosion control measures. • Limit disturbance during construction to the minimum necessary to efficiently complete construction activities. • Complete construction, cleanup, and reclamation as quickly as possible to keep the time period between grading, trench excavation, backfilling, and final restoration/reclamation to a minimum. • Minimize cut and fills to reduce the amount of exposed slopes. 4.3.1 Installation Detailed information on best management practices and installation of sediment barriers, waterbars, erosion control matting, and mulch is provided in EnCana's Soil Conservation, Sedimentation, and Erosion Control Plan and Stormwater Pollution Prevention Plan. Piceance Gathering Pipeline Project 27 April 2006 Garfield County Development Plan 4.3.2 Inspection During construction, erosion control structures will be inspected daily in areas of active construction or equipment operation, on a weekly basis in areas with no construction or equipment operation, and in all areas within 24 hours of each 0.5 -inch or greater rainfall event, soil and weather conditions permitting. Erosion control monitoring and maintenance efforts will continue after project construction until successful revegetation is achieved as defined in the Reclamation Plan. Throughout the first year following construction, erosion control devices will be checked at all locations along the right- of-way in combination with reclamation and revegetation surveys. Erosion control devices will be reinstalled, repaired, and/or maintained as necessary. 4.3.3 Maintenance All erosion and sediment controls and other protective measures will be maintained in an effective operating condition. If site inspections indicate that best BMPs are not operating effectively, maintenance will be performed promptly, within 24 hours and before the next anticipated storm event, to maintain continued effectiveness of stormwater pollution controls. 4.3.4 Site -Specific BMPs EnCana has completed a preliminary pre -construction stormwater evaluation of the project in Garfield County. In addition to the general measures listed in EnCana's Soil Conservation, Sedimentation and Erosion Control Plan and Stormwater Pollution Prevention Plan, EnCana plans to implement the following site-specific measures: Site -Specific Stormwater Management Practices Feature Milepost Stormwater BMP Culvert inlets 34 culverts between -4.2 and 6.5 Gaps will be left in topsoil and subsoil stockpiles to allow water to travel freely to/through the culvert. Culvert outlets 34 culverts between -4.2 and 6.5 Straw bales or silt fence installed to trap sediment. Waterbodies (parallel to workspace) 5.4 to 6.7; 14.8 to 18 0 Silt fence, straw bales, or equivalent will be installed parallel to the right-of-way in areas where there is insufficient vegetation to prevent sediment from entering waterbodies. Waterbodies (flowing crossings) 4.9, 5.4 Silt fence, straw bales, or equivalent will be installed across the right-of-way to prevent sediment from entering waterbodies. Side slopes 2.4 to 4.9, 5.6 to 7.2, various between 12.5 and 20.4 Straw mulch will be applied on slopes steeper than 30 percent. Erosion control matting will be installed on slopes steeper than 40 percent. Rock mulch or equivalent may be substituted for straw mulch and erosion control matting. 28 Piceance Gathering Pipeline Project April 2006 Garfield County Development Plan Site -Specific Stormwater Management Practices Feature Milepost Stormwater BMP Waterbars will typically be installed every 300 feet on slopes between 5 and 15 percent, every 200 feet on slopes between 15 Ascent -descent 7.2 to 12.5, various and 30 percent, and every 100 feet on slopes steeper than 30 slopes between 12.5 and percent. Straw mulch will be applied on slopes steeper than 30 20.4 percent. Erosion control matting will be installed on slopes steeper than 40 percent. Rock mulch or equivalent may be substituted for straw mulch and erosion control matting. Site-specific BMPs are subject to change/refinement based on actual construction conditions. Exact locations of culverts and waterbodies are depicted on the alignment sheets. Side slopes and ascent -descent slopes are visible on the alignment sheets.

The holder shall minimize construction impacts to air quality by acquiring Colorado Department of Public Health and Environment (CDPHE) Air Pollution Control Division (APCD) construction emissions permits, complying with permit stipulations, and implementing emission control measures proposed in EnCana's Fugitive Dust Control Plan (EnCana 2005g), included in the Plan of Development (EnCana 2005a). The holder shall: • Maintain and tune equipment to manufacturers' specifications. • Transport the majority of workers from contractor yards to the construction site in buses provided by the contractor. • Limit opacity of fugitive dust to 20 percent or less. • Apply water and/or an approved dust suppressant on unpaved roads and construction workspaces. • Clean soil tracked onto paved roads more than 50 feet from the point of origin within one hour of discovery and clean soil tracked less than 50 feet from the point of origin by the end of the working day. • Cease construction operations when wind speeds exceed 30 miles per hour (mph). • Limit vehicle speed to 15 mph on the right-of-way and to posted speed limits on roads. • Seed disturbed areas as discussed in the Vegetation section. 2. The holder will obtain permits for regulated air pollution sources through the CDPHE APCD to ensure compliance with all federal and state air quality standards, and would comply with all county and state permit conditions and stipulations. 3. Construction activities would remain inside the existing disturbance footprint (125 feet wide) within the. Ryan Gulch ACEC between Meeker -South mileposts 42.6 and 43.4. 4. The holder shall minimize impacts to cultural resources by implementing the following measures. These measures will be incorporated into EnCana's Cultural Resources Protection Plan (EnCana 2005d), included in the Plan of Development (EnCana 2005a). The holder shall: Exhibit M Page 2 of 22 • Avoid known cultural resource sites by realigning the centerline, removing temporary use areas, not utilizing the entire construction workspace, and/or completing data recovery. • Test recommended sites to determine eligibility to the NRHP. If the sites were not eligible, no further mitigation would be necessary. If the sites are eligible, either the sites would be avoided by shifting the centerline or data recovery would occur. • Monitor eight sites (4 previously recorded, 3 newly recorded, and 1 potential area) within or adjacent to the right-of-way during construction. • Monitor construction activities within the Canyon Pintado NHD. • Inform all persons associated with the project that they would be subject to prosecution for knowingly disturbing historic or archaeological sites, or for collecting artifacts. If historic or archaeological materials are uncovered during any project or construction activities, activities would stop in the immediate area of the find, and the BLM Authorized Officer would be immediately contacted. Within five working days, the BLM Authorized Officer would inform the holder as to: ▪ whether the materials appear eligible for the NRHP,. - the mitigation measures the holder will likely have to undertake before the site can be used (assuming in situ preservation is not practicable), and - a timeframe for the BLM Authorized Officer to complete an expedited review under 36 CFR 800.11 to confirm, through the SHPO, that the findings of the BLM Authorized Officer were correct and that mitigation was appropriate. • Notify the BLM Authorized Officer by telephone and with written confirmation, immediately upon discovery of human remains, funerary items, sacred objects, or objects of cultural patrimony. Activities would stop in the immediate area of the find, and the discovery would be protected for 30 days or until notified to proceed in writing by the BLM Authorized Officer. 5. The holder shall minimize impacts to prime farmland soils by implementing measures for the proper handling of topsoil and spoil, erosion control, and reclamation procedures as proposed in EnCana's Reclamation Plan (EnCana 2005j), Noxious Weed Management Plan (EnCana 2005h), and Soil Conservation, Sedimentation, and Erosion Control Plan (EnCana 20051) included in the Plan of Development (EnCana 2005a). The holder shall: • Segregate up to 12 inches of topsoil from the entire construction workspace and temporary use areas, unless requested otherwise by the fee -landowner, to prevent mixing of topsoil and subsoil layers. Exhibit M Page 3 of 22 • Stockpile topsoil separately from subsoil. • Compact the pipeline trench during backfill activities to prevent subsidence. • Rip or plow compacted subsoil at least 6 to 10 inches deep before replacing segregated topsoil across the right-of-way. • Return topsoil to pre -construction depths and locations. • Remove rocks from the top 12 inches of soil and make diligent efforts to remove stones greater than 4 inches in any dimension if the off -right-of-way areas do not contain stones greater than 4 inches in any dimension. 6. The holder shall mitigate impacts to floodplains by implementing measures proposed in EnCana's Waterbody Crossing and Wetland Protection Plan (EnCana 2005q), included in the Plan of Development (EnCana 2005a).

(EnCana) and its contractors (Contractor) during construction, operation, and maintenance of the Piceance Gathering Pipeline Project (project). Preparation of the Plan of Development is required by the Bureau of Land Management (BLM). The primary objective of the Plan of Development is to establish procedures for implementation of best management practices and mitigation measures in the Environmental Assessment for the project. Measures identified in this plan apply to work within the project area defined as the right-of-way, access roads, temporary use areas, and other areas used during construction of the project. EnCana and Contractor personnel are to be thoroughly familiar with this plan and its contents prior to initiating construction on the project. 1.1 Purpose The purpose of this Plan of Development is to provide guidelines for the construction, future operations, and maintenance of the project in compliance with mitigation measures set forth in the Environmental Assessment. The Plan of Development contains general information on the project and is not intended as a stand-alone document. Detailed information concerning specific project -related activities such as fire prevention and suppression, soil conservation and erosion control, and waterbody and wetlands protection are provided in the Plan of Development appendices. Detailed maps and drawings are referenced throughout this document and included as Attachment 1. Fee -landowner requirements are included as Attachment 2. 1.2 Overview The Plan of Development contains an introduction, a detailed discussion of the proposed construction activities, and a description of operation and maintenance activities. hi addition, the following environmental compliance plans are attached to the Plan of Development as appendices.

The project will involve the construction and operation of a natural gas processing plant and 205 miles of up to 36 -inch diameter buried natural gas, natural gas liquids (NGL) and water pipelines and related aboveground appurtenances in Garfield and Rio Blanco Counties, Colorado, and Uintah County, Utah. The Piceance Gathering Pipeline Project is a portion of that project and involves construction of approximately 49 miles of 36 -inch diameter natural gas pipeline and related aboveground appurtenances. 2.1 Purpose and Need EnCana plans to increase production in the Piceance Basin by approximately 100 to 200 million standard cubic feet per day (mscfd), each year, for the next several years. The Meeker Project will provide a natural gas gathering and processing system that will transport and process the projected future volumes of natural gas from the western slope of Colorado and the Rocky Mountain region to major interconnections with other interstate pipelines. The proposed pipelines will transport approximately 1 Bscfd of natural gas from the Piceance Basin of western Colorado to existing inter- and intrastate pipelines operated by Questar, Kinder Morgan, Mid - American Pipeline Company (MAPCO), Northwest, Rocky Mountain Natural Gas (RMNG), Colorado Interstate Gas (CIG) and Entrega. 2.2 Pipeline Facilities 2.2.1 Description The proposed project is approximately 49 miles of 36 -inch diameter natural gas pipeline and related aboveground facilities. The project route is depicted in Attachment 1. Pipelines which are subject to federal regulations will be designed and constructed in conformance with the requirements of Title 49 CFR, Part 192, "Regulations for the Transportation of Natural and Other Gas by Pipeline: Minimum Federal Safety Standards". 2.2.2 Right -of -Way The nominal construction right-of-way width will is 120 feet. Following construction of the pipeline, the width of the right-of-way will be reduced to a permanent right-of-way width of 45 feet. The typical right-of-way configuration is depicted in Attachment 1. The proposed pipeline will generally be installed at the edge of existing Kinder Morgan, CIG, Questar, or EnCana permanent rights -of -ways using a standard 25 -foot offset from the existing pipelines. At certain locations, the proposed route deviates from this standard offset configuration due to terrain and/or environmental features. EnCana will utilize temporary use areas where additional right-of-way width will be required at foreign pipeline and road crossings, waterbody crossings, and steep side and ascent -descent slopes. Piceance Gathering Pipeline Project 3 March 2006 Plan of Development 2.2.3 Ancillary Facilities 2.2.3.1 Access Roads EnCana will use existing roads to gain access to the right-of-way during construction. These access roads are primarily gravel and/or dirt roads utilized during installation of the existing Kinder Morgan, CIG, Questar, and EnCana pipelines. Access roads are listed in the Transportation Plan (Appendix 15). 2.2.3.2 Contractor/Pipe Storage/Offloading Yards EnCana proposes to use contractor, pipe storage, and offloading yards on a temporary basis to support construction activities. These yards have typically been previously disturbed, are located on privately owned land, and have been used for similar activities in the past. 2.2.3.3 Aboveground Appurtenances Associated aboveground appurtenances proposed by EnCana include meter stations, block valves, cathodic protection equipment, and pipeline markers. Meter stations will be required at each interconnect/outlet to existing/proposed pipelines. In addition to meters, the meter stations will consist of gas quality measurement equipment, valves, and related piping located within prefabricated metal buildings. The perimeter of the facility will be surrounded with suitable security fencing. Sectionalized block valves will be installed with the pipelines at locations dictated by project design and at intervals required by Department of Transportation (DOT) regulations. The perimeter of the block valve sites will be surrounded by suitable security fence. Locations, land ownership, and land requirements for the block valves have not yet been determined. Cathodic protection equipment will be installed as necessary along the pipelines. Exact placement and type of equipment has not yet been designed. The pipeline location will be marked with aboveground pipeline markers in accordance with DOT safety requirements. 2.2.4 Construction Schedule The project will be constructed beginning summer 2006. Construction activities are anticipated to last 6 months. 4 Piceance Gathering Pipeline Project March 2006 Plan of Development 3.0 CONSTRUCTION ACTIVITIES The following section provides a description of each phase of standard construction along the right-of-way. Also included in these sections are specific applicable mitigation requirements that will be implemented by the Contractor. 3.1 Project Area Surveying and Staking 3.1.1 Pre -Construction Pre -construction surveys and literature review were conducted to identify sensitive resources along the project route. Resources identified include: sensitive wildlife (e.g., mule deer, elk, sage grouse, and raptor) populations and habitat; sensitive plant populations; cultural and paleontological resources; wetlands and waterbodies; and areas of potential geologic instability. Mitigation for sensitive areas that cannot be avoided is addressed in environmental compliance plans included in this document (e.g., Reclamation Plan, Waterbody Crossing and Wetland Protection Plan, Cultural Resources Protection Plan, Biological Resources Protection Plan, etc). Prior to construction, final pre -construction surveys for noxious weed infestations and nesting raptors will be conducted in spring 2006 along the right-of-way in accordance with the Biological Resources Protection Plan. The field survey results will be used to identify sensitive resource construction buffer areas and areas requiring special protective signing, flagging, or fencing. 3.1.2 Construction Civil engineering surveys will be performed by EnCana to identify the centerline of the pipeline and the boundaries of both sides of the approved working limits before construction activities commence. Flagged or painted lath will be set at 200 -foot intervals (maximum), or as required to maintain line of sight, along the proposed centerline. The edges of the work limits will be marked at 200 -foot intervals (maximum), or as required to maintain line of sight, with flagged or painted lath. All temporary use areas will be marked in a similar fashion and all four corners of each temporary use area will be marked by a flagged or painted lath. EnCana's Construction Inspectors will be responsible for verifying that the limits of authorized construction work areas are staked prior to construction. 3.2 Clearing, Grading, and Topsoiling Fences crossing the right-of-way will be braced, cut, and temporarily fitted with gates to permit passage. Prior to cutting or replacing the fences, EnCana will notify the grazing permittees and fee -landowners and give them the opportunity to be present when the fence is cut. During construction, the opening will be controlled to prevent the escape of livestock. During construction, the Contractor will not obstruct or damage gates or cattleguards. Any damage will be repaired to the BLM and/or fee -landowner satisfaction. BLM fence specifications are included in Attachment 3. Vegetation will be cleared and the construction right-of-way graded to provide for safe and Piceance Gathering Pipeline Project 5 March 2006 Plan of Development efficient operation of construction equipment and inspection vehicles, and to provide space for the storage of subsoil and topsoil. Construction activity and ground disturbance will be limited to approved, staked areas. Where tree clearing is necessary, any specimen trees on the perimeter will be flagged for avoidance by EnCana's Environmental or Construction Inspector or the BLM Authorized Officer or field representative. Where feasible, clearing will be feathered to eliminate the straight line effect and to soften the visual impact. Trees will be cut with a chain saw and/or mechanical shears and brush will be generally cut with a hydraxe or similar equipment. Trees and brush will be cut as close to the ground as possible. Stumps will be left in place except over the trenchline or as necessary to create a safe and level workspace. Trees will be felled inside the approved right-of-way boundaries. On BLM lands, EnCana will be required to acquire a Fuel Woods Permit and compensate the BLM for trees. On BLM lands administered by the White River Field Office (WRFO), 3 to 5 tons/acre of brush and trees will be salvaged whole. Trees will be windrowed adjacent to the right-of-way or temporary use areas providing that equipment stay within the approved right-of-way boundaries. Following construction, these materials will be evenly dispersed over the portion of the right-of- way from which the trees and brush were originally removed to impede future access along the right-of-way and to provide wildlife habitat. Remaining brush and trees will be shredded or chipped and salvaged with the topsoil. Timber will be made available to the public for firewood or fence posts. This wood will be de -limbed, cut in 4- to 8 -foot lengths, and stockpiled on the right-of-way or within approved temporary use areas at points where the right-of-way crosses access roads (in a manner such that the stockpiled wood will not hinder reclamation efforts). On fee -lands, brush and other materials cleared from the right-of-way will typically be chipped or shredded and incorporated into the topsoil. Fee -landowner requirements will be listed in the Fee -Lands Line List, included in Attachment 2. Topsoil will be segregated using one of the following methods: from either the full -work area (full -right-of-way method), from the trenchline only (trenchline only method), or from the trenchline and working side (trench and working side method). Topsoil will not be stripped across the centerline of existing pipelines. On WRFO BLM lands, all available topsoil up to a depth of 6 inches will be removed from the trenchline only. On any lands requiring grading, topsoil will be stripped from the entire portion of the right-of-way that requires grading. On fee -lands, topsoil will generally be stripped up to a depth of 6 inches from the trenchline; however, at the fee -landowner's request, more than 6 inches of topsoil may be salvaged and/or topsoil will be salvaged across the full -width of the right-of-way or a portion thereof. On any lands requiring grading, topsoil will be stripped from the entire portion of the right-of-way that requires grading. Up to 12 inches of topsoil will be stripped across the full -width of the right-of- way in irrigated agricultural lands. Fee -landowner requirements will be listed in the Fee -Lands Line List. 6 Piceance Gathering Pipeline Project March 2006 Plan of Development Topsoil will be stockpiled separate from subsoil and will not be used to pad the trench or construct trench breakers. 3.2.1 Clearing, Grading and Topsoiling Requirements The Contractor will implement the following mitigation measures during clearing, grading and topsoiling operations: • Brace and secure each fence crossed before cutting the opening needed for construction to prevent slacking of the wire. The opening will be closed by temporary gates as necessary or as requested by the fee -landowner to prevent passage of livestock. Fences will be braced and secured in accordance with BLM specifications (included in Attachment 3). • Install temporary fencing as required by pre -construction agreements with fee -landowners to prevent livestock entry into the construction right-of-way. • Protect all survey monuments found within the right-of-way. Survey monuments include, but are not limited to, General Land Office and BLM Cadastral Survey Comers, reference corners, witness points, U.S. Coastal and Geodetic benchmarks and triangulation stations, military control monuments, and recognizable civil (both public and private) survey monuments. • Report any survey monuments found within the right-of-way or temporary use areas that are disturbed or obliterated during the course of the project to EnCana. EnCana will report it in writing to the BLM Authorized Officer and the respective installing authority, if known. • Limit clearing and vegetation removal to the extent practical to provide for safe construction. • Minimize vegetation removal to the extent necessary to allow for safe and efficient construction activities. • Cut trees with a chain saw and/or mechanical shears and cut brush with a hydraxe or similar equipment as close to the ground as possible. • Leave stumps and root balls in place except over the trenchline, areas requiring topsoiling, or as necessary to create a safe and level workspace. Fell trees inside the approved right-of-way boundaries. • Use non-linear right-of-way clearing techniques (feathering) to minimize visual impacts, where feasible. • Dispose of cleared vegetation as required: BLM WRFO lands—Salvage 3 to 5 tons/acre of brush and trees. Stockpile material for later use in reclamation. Remaining brush and trees may be shredded or chipped and salvaged with topsoil or may be made available to the public as firewood or Piceance Gathering Pipeline Project 7 March 2006 Plan of Development fenceposts. De -limb the wood, cut in 4- to 8 -foot lengths, and stockpile on the right- of-way or within approved temporary use areas at points where the right-of-way crosses access roads. - Fee-lands—Shred or chip brush and salvage with topsoil, unless specified otherwise. • Minimize cut and fill in order to reduce the amount of soil exposed to erosion. • Salvage topsoil as required: - BLM WRFO lands—up to 6 inches across the trenchline only. Fee-lands—unless otherwise directed by the fee -landowner, up to 6 inches across the trenchline, except irrigated agricultural fields where up to 12 inches will be stripped across the entire right-of-way. Any areas requiring grading—up to 6 inches across the entire right-of-way. • Stockpile topsoil separately from subsoil to prevent mixing of soil layers. • Prohibit use of topsoil to pad the trench or construct trench breakers. • Avoid blocking dry drainages or washes that cross the right-of-way with topsoil. Stockpile topsoil on the banks of the drainage. Leave gaps periodically in the topsoil windrow to avoid ponding and excess diversion of natural runoff during storm events. • Install temporary erosion control measures in accordance with the Soil Conservation, Sedimentation, and Erosion Control Plan. 3.3 Trenching and Blasting Construction methods used to excavate a trench will vary depending on soils, terrain, and related factors. Trenching machines will be used where possible. In situations such as steep slopes, unstable soils, high water table, or deep or wide trench requirements, trackhoes will generally be used. Access will be provided for fee -landowners and grazing permittees to move vehicles, equipment, and livestock across the trench where necessary. EnCana will contact livestock operators and provide adequate crossing facilities as needed to ensure livestock are not prevented from reaching water sources because of the open trench. The Contractor will keep wildlife and livestock trails open and passable by adding soft plugs (areas where the trench is excavated and replaced with minimal compaction) during the construction phase. Soft plugs with ramps on either side will be left at all well-defined livestock and wildlife trails and at maximum 1 -mile intervals to allow access across the trench and provide a means of escape for livestock and wildlife that may fall into the trench. 8 Piceance Gathering Pipeline Project March 2006 Plan of Development A typical trench will be excavated approximately 36- to 48 -inches wide at the bottom and the sides will be sloped to Occupational Safety and Health Administration (OSHA) specifications. The depth of the ditch will be approximately 80- to 100 -inches deep. The depth and width of the ditch will vary depending upon soil types. The cover from top of pipe to ground level as graded to finished right-of-way will be in conformance with DOT regulations. Greater depths of cover will be required at unpaved road crossings, foreign pipeline crossings, waterbodies, and other obstructions. Where the pipeline traverses locations for which there are definite plans to level the land for irrigation or other purposes, the pipe will be buried at a depth to accommodate these plans. The Contractor will utilize the "One Call" system to locate and stake the centerline and limits of all underground facilities in the area of proposed excavation. The Contractor will provide 48- hour notification to the owner/operator of and foreign pipeline prior to performing any work within 10 feet of buried or aboveground -pressurized gas piping. Machine excavation will not be performed closer than 5 feet from any existing pipeline encountered in the right-of-way unless authorized by the pipeline owners/operators. At a minimum, the ditch will be excavated to allow 24 inches of clearance (unless otherwise specified by the foreign pipeline owner/operators) between EnCana pipelines and other pipelines or underground facilities. Paved roads will typically be bored to avoid disrupting traffic in accordance with the governing agency requirements and permitting agreements. Unsurfaced or lightly traveled roads will be crossed using a mechanical ditching machine or a trackhoe. Installation at these locations, including cleanup and restoration of road surfaces, will usually be completed within one day. In such cases, provisions will be made to detour or control passage of traffic during construction. Where rock is encountered, tractor -mounted mechanical rippers or rock trenching equipment may be used to facilitate excavation. In areas where rippers or trenchers are not practical or sufficient, blasting may be employed. Blasting will be used only where necessary. Normally, the effects of blasting are confined to the pipeline right-of-way. Where rock formations are encountered and blasting is necessary, all necessary authorizations will be obtained and all safety precautions observed. All blasting work will be conducted in compliance with federal, state, and local laws, rules, and regulations. The Contractor is responsible for obtaining permits to store blasting materials on BLM lands. After blasting has been completed, trackhoes will be used to clean the ditch for pipe installation. See the Blasting Plan for additional blasting requirements. Excavated subsoil will be stored separate from windrowed topsoil piles. Subsoil will not be stored in flowing waterbodies and dry drainages or washes that cross the right-of-way will not be blocked with subsoil. Subsoil will be placed on the banks of the drainage. Gaps will be left periodically in the subsoil piles to avoid ponding and excess diversion of natural runoff during storm events. Piceance Gathering Pipeline Project 9 March 2006 Plan of Development 3.3.1 Trenching Requirements The Contractor will implement the following mitigation measures during trenching operations: • Utilize the "One Call" system to locate and stake the centerline and limits of all underground facilities in the area of proposed excavation. • Provide 48-hour notification to the owner/operator of and foreign pipeline prior to performing any work within 10 feet of buried or aboveground -pressurized gas piping. • Prohibit machine excavation within 5 feet from any existing pipeline encountered in the right-of-way unless authorized by the pipeline owners/operators. • Stockpile subsoil separate from topsoil stockpiles. • Prohibit use of topsoil to pad the trench or construct trench breakers. • Avoid blocking dry drainages or washes that cross the right-of-way with subsoil. Stockpile subsoil on the banks of the drainage. Leave gaps periodically in the subsoil windrow to avoid ponding and excess diversion of natural runoff during storm events. • Install livestock crossovers (trench plugs), with ramps on either side of the open trench, at maximum 1 -mile intervals and at well-defined livestock and wildlife trails to facilitate passage of livestock, wildlife, and wild horses across the right-of-way and to prevent animals from becoming trapped in the trench. • Maintain water flow in irrigation ditches crossed by the pipeline at all times unless arrangements are made with the affected parties to temporarily shut off the flow of water. 3.4 Pipe Installation Pipe installation will include stringing, bending for horizontal or vertical angles in the alignment, welding the pipe segments together, inspection, coating the joint areas to prevent corrosion, and then lowering -in and padding as described in greater detail below. 3.4.1 Stringing Line pipe will be shipped directly from the manufacturer by rail to pipe yards and then hauled by stringing trucks to the pipeline right-of-way. Each individual joint of pipe will be unloaded with a sideboom or trackhoe fitted with a vacuum device and placed (strung) parallel to the ditch in a continuous line. Sufficient pipe for road or waterbody crossings will be stockpiled at staging areas near the crossings. Stringing operations will be coordinated with trenching and installation activities in order to properly manage the construction time at a particular tract of land. Gaps will be left at access points across the ditch to allow crossing of the right-of-way. 10 Piceance Gathering Pipeline Project March 2006 Plan of Development 3.4.2 Bending After joints of pipe are strung along the ditch but before the joints are welded together, individual joints of pipe will 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 or segmented joints will be installed. 3.4.3 Welding After pipe joints are bent, the pipe joints will be lined up end-to-end and clamped into position. The natural gas pipelines will be welded in conformance with 49 CFR Part 192, Subpart E. "Welding of Steel Pipelines" and API 1104, "Standard for Welding Pipelines and Related Facilities," latest edition approved by DOT. 3.4.4 Inspection All welds will be visually inspected by a qualified inspector. Non-destructive radiographic inspection methods will be conducted in accordance with DOT requirements. A specialized contractor will be employed to perform this work. Any defects will be repaired or cut out as required under the specified regulations and standards. 3.4.5 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 a tape wrap, shrinkable sleeve wrap, or field -applied fusion bond epoxy. 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 (holidays) will be repaired. 3.4.6 Lowering -in and Padding Before the pipe section is lowered into the ditch, inspection will be conducted to verify that the pipe is properly fitted and installed into the ditch, minimum cover is provided, and the trench bottom is free of rocks and other debris that could damage the external pipe coating. Dewatering may be necessary where water has accumulated in the trench, and will occur in accordance with the Soil Conservation, Sedimentation, and Erosion Plan. Side -boom tractors will be used to simultaneously lift the pipe section, position it over the ditch, and lower it in place. Padding machines will be used to sift soil fines from the excavated subsoils to provide rock -free pipeline padding and bedding. Sandbags may be used to pad the bottom of the ditch instead of, or in combination with, padding with soil fines. In rocky areas, padding material or a rock shield will be used to protect the pipe. No topsoil will be used to pad the pipe. 3.5 Backfilling Backfilling will begin after a section of pipe has been successfully placed in the ditch. Backfill will be conducted using a bulldozer, rotary auger backfiller, padding machine, or other suitable equipment. Backfilling the trench will generally use the subsoil previously excavated from the trench, except in rocky areas where imported select fill material maybe needed. Backfill will be Piceance Gathering Pipeline Project 11 March 2006 Plan of Development graded and compacted, where necessary for ground stability, by tamping or walking with a wheeled or tracked vehicle. Compaction will be performed to the extent that there are no voids in the trench. Backfill of trenches will not be performed where the soil is frozen to the extent that large consolidated masses are formed that will not break down. In irrigated agricultural areas, the backfill will be replaced at the same compaction density as the adjacent undisturbed soil. Any excavated materials or materials unfit for backfill will either be utilized elsewhere or properly disposed of in conformance with applicable laws or regulations. 3.5.1 Backfilling Requirements The Contractor will implement the following mitigation measures during backfilling operations: • Construct trench breakers in accordance with the Soil Conservation, Sedimentation, and Erosion Control Plan. • Avoid backfilling rock above the existing bedrock profile. • Place a mound over the trench approximately 0.5 -foot in height to account for subsidence. Written authorization from the fee -landowner is required to eliminate the mound. 3.6 Strength Testing The pipeline will be tested in compliance with DOT regulations (49 CFR Parts 192). Prior to filling the pipeline for a hydrostatic or pneumatic test, each section of the pipeline will be cleaned by passing reinforced poly pigs through the interior of the line. Incremental segments of the pipeline will then be filled with water or nitrogen, pressurized, and held for the duration of the test. The length of each segment tested will depend on topography. Typically, the hydrostatic tests of individual segments will be conducted in sequence and the test water will be transferred from one segment to another. Test water will be obtained from approved sources. Sources for test water are included in the Strength Testing Plan. Water for hydrostatic testing will be appropriated from various sources utilizing portable pumps driven by diesel engines. To prevent environmental damage from potential diesel fuel spills during the operation of the engine(s), additional measures will be implemented when the pumps are located within 200 feet of a waterbody or wetland as described in the Strength Testing Plan. Test water will be discharged to approved locations in accordance with applicable permit requirements. 3.6.1 Strength Testing Requirements The Contractor will implement the following mitigation measures during strength testing operations: • Withdraw and discharge hydrostatic test water in accordance with all applicable permits. 12 Piceance Gathering Pipeline Project March 2006 Plan of Development • Test water quality during withdrawal and discharge in accordance with permit stipulations and conditions. • Utilize screens on the intake hoses at surface water sources to prevent the entrapment of fish or other aquatic species and monitor the appropriation rate to ensure that adequate downstream flow is maintained to support aquatic life. • Install energy -dissipating devices and/or filter bags to prevent scour, erosion, suspension of sediment, and damage to vegetation. Monitor discharge rates to ensure effectiveness of the energy -dissipating device. 3.7 Cleanup and Restoration Cleanup and restoration will occur after the pipeline is installed, and will begin after backfill activities are completed. Cleanup of the surface along the right-of-way and any temporary use areas will be performed by removing any construction debris and by performing final grading to the finished contour. Erosion control measures will be installed as described in the Soil Conservation, Sedimentation, and Erosion Control Plan. Restoration seeding will be performed in accordance with fee -landowner and BLM requirements as described in the Reclamation Plan. 3.7.1 Cleanup and Restoration Requirements The Contractor will implement the following mitigation measures during cleanup and restoration activities: • Restore pre -construction contours and drainage patterns. • Decompact subsoil to a depth of 6 to 10 inches prior to topsoil replacement. Decompact topsoil as necessary in areas where topsoil was not salvaged. • Return topsoil to pre -construction depths and locations. • Remove rocks larger than four inches in any dimension from the restored topsoil in all irrigated agricultural areas. In all other areas, remove rocks to match approximate pre - construction conditions. Excess rock may be randomly distributed across the right-of-way to block use of the right-of-way by motor vehicles in selected areas. Any rocks removed from the right-of-way will be disposed of in an approved disposal site. EnCana will coordinate with fee -landowners and the BLM regarding the methods of disposal. • Use vegetative mulch and excess rock to reduce erosion potential by providing additional surface relief structure. Distribute vegetative debris salvaged during clearing and grading operations across the right-of-way, as discussed below. - Layer rock on the surface of erodible soils in critical areas to reduce erosion and restore appearance of native surface. Piceance Gathering Pipeline Project 13 March 2006 Plan ofDeveloptnent Apply mulch on slopes 30 percent or steeper. Install erosion control matting on slopes 40 percent or steeper. • Seed disturbed areas with the goals of replacing suitable wildlife habitat and browse and providing a vegetative cover that stabilizes soils to control erosion and sedimentation. Typical seed mixes will reflect environmental conditions and ecological range sites along the project route and emphasize the use of native species. Seed mixes, rates, and application areas are provided in the Reclamation Plan. • Use certified weed -free seed purchased from and blended by qualified producers and dealers. • Employ drill or broadcast seed methods to ensure proper seed placement. Drill seeding is preferred and will be used wherever soil characteristics and slope allow effective operation of a rangeland seed drill. Drill seeding will be performed perpendicular to the slope. Seed will be placed in direct contact with the soil at an average depth of 0.5 -inches, covered with soil, and firmed to eliminate air pockets around the seeds. Broadcast seeding will be employed only in areas where drill seeding is unsafe or physically impossible. Seed will be applied uniformly over disturbed areas with manually operated cyclone -bucket spreaders, mechanical spreaders, or blowers. Broadcast application rates will be twice that of drill rates. The seed will be uniformly raked, chained, dragged, or cultipacked to incorporate seed to a sufficient seeding depth. • Complete drill and/or broadcast seeding prior to redistribution of woody material. • Redistribute large, woody material salvaged during clearing operations on WRFO- administered lands. Disperse materials over the portion of the right-of-way from which the trees and brush were originally removed to meet fire management objectives and to provide wildlife habitat, seedling protection and a deterrent to vehicular traffic. Woody materials dispersed across the right-of-way will not exceed 3 to 5 tons/acre. • Install erosion control measures in accordance with the Soil Conservation, Sedimentation, and Erosion Control Plan. • Repair all irrigation ditches, cattle guards, fences, and artificial and natural livestock and wildlife water sources to at least pre -construction conditions. BLM specifications are provided in Attachment 3. • Establish and maintain permanent enclosures on each of the mid- and high -elevation sage grouse habitat intervals. Enclosures will be established as a means of determining the ultimate success of forbs in the reclamation seed mix and will be designed to exclude cattle and wild horses, with dimensions of 100 feet paralleling the right-of-way and a width that spans the fully authorized temporary construction right-of-way. The location of these structures will be subject to approval of the BLM Authorized Officer. The general location on BLM lands is milepost 23.0 and 24.0 (mid -elevation sage grouse habitat). The BLM 14 Piceance Gathering Pipeline Project March 2006 Plan of Development requests that, in the interest of sage grouse conservation, EnCana arrange to establish a similar enclosure on private lands in the high elevation segment south of Meeker -South milepost 22.0. 3.8 Livestock Barrier and Other Livestock Issues Fences crossing the right-of-way will be braced, cut, and temporarily fitted with gates to permit passage. During construction, the opening will be controlled to prevent the escape of livestock. Existing fences will be replaced and braces left in place upon completion of construction activities. Prior to cutting or replacing the fences, EnCana will notify the grazing permittees and fee -landowners and give them the opportunity to be present when the fence is cut. During construction, the Contractor will not obstruct or damage gates or cattleguards. Any damage will be repaired to the BLM and/or fee -landowner satisfaction. EnCana will provide compensation or interim measures for any critical facilities (such as watering sites) that are disrupted during the construction or restoration process through prior agreements with grazing permittees or fee -landowners. 3.8.1 Livestock Related Requirements The Contractor will implement the following mitigation measures relating to livestock: • Brace and secure each fence crossed before cutting the opening needed for construction to prevent slacking of the wire. The opening will be closed by temporary gates as necessary or as requested by the fee -landowner to prevent passage of livestock. Fences will be braced and secured in accordance with BLM specifications (included in Attachment 3). • Install temporary fencing as required by pre -construction agreements with fee -landowners to prevent livestock entry into the construction right-of-way. • Maintain the current condition and usability of stock ponds and other facilities along the right-of-way. • Install livestock crossovers (trench plugs), with ramps on either side of the open trench, at maximum 1 -mile intervals and at well-defined livestock and wildlife trails to facilitate passage of livestock across the right-of-way and to prevent livestock from becoming trapped in the trench. • Restore damaged livestock fences, gates, cattleguards, and brace panels to BLM or fee - landowners specifications. 3.9 Health and Safety 3.9.1 Health and Safety Requirements The Contractor will implement the following health and safety measures: Piceance Gathering Pipeline Project 15 March 2006 Plan of Development • Comply with requirements listed in the Safety Plan, Fire Prevention and Suppression Plan, Blasting Plan, Strength Testing Plan, and the Spill Prevention, Containment, and Countermeasure Plan. • Cease construction activities, with the exception of strength testing operations, by sunset. Nighttime construction (with the exception of strength testing) will not be permitted unless approved by EnCana. • Prohibit camping on the right-of-way. • Control fugitive dust in accordance with the Fugitive Dust Control Plan and any applicable county, state, or federal permit requirements. • Properly maintain and muffle equipment to reduce emissions and noise. • Prohibit burning of brush or debris, and campfires, lunch fires, or warming fires on the right- of-way in accordance with the Fire Prevention and Suppression Plan. 3.10 Waste Disposal 3.10.1 Waste Disposal Requirements The Contractor will implement the following waste disposal measures: • Prohibit littering on the right-of-way. Construction and operations sites will be maintained in a sanitary condition at all times and waste materials at these sites will be disposed of promptly at an appropriate waste disposal site. Waste is defined as all discarded matter including, but not limited to, human waste, trash, garbage, refuse, oil drums, petroleum products, blasting boxes, and equipment. • Dispose of excess or unsuitable materials at commercial disposal sites, commercial recycling centers, and disposal sites approved by EnCana. • Store and dispose hazardous wastes in accordance with the Spill Prevention, Containment, and Countermeasure Plan. • Remove human wastes, temporarily located within self-contained facilities (portable toilets), from the right-of-way and dispose of in accordance with applicable laws and regulations. 4.0 OPERATION AND MAINTENANCE ACTIVITIES EnCana will be responsible for monitoring pipeline operations after construction is completed. Maintenance and operating personnel will be coordinated from district offices so that any area can be reached within a short period in case of an emergency or malfunction. These personnel will be qualified and trained employees of EnCana. 16 Piceance Gathering Pipeline Project March 2006 Plan of Development EnCana's pipeline system will be operated and maintained in accordance with industry standard procedures to ensure safe operation and to maintain the integrity of its pipeline system. Operation and maintenance procedures for DOT regulated pipelines will be developed in accordance with the safety standards outlined in 49 CFR Parts 191 and 192 and other applicable regulations. These procedures will continue to be implemented during the operations and maintenance of the pipeline facilities. 4.1 Right -of -Way Access Surface travel along the right-of-way will generally be limited to periodic valve inspections, leak surveys, right-of-way maintenance, and any pipeline repairs that may be needed. In addition to the above activities, it will also be necessary to access the right-of-way for the following: • corrosion control survey crews, • noxious weed control surveys and maintenance (in conformance with the Noxious Weed Management Plan), and • periodic monitoring of irrigation ditches and irrigated agricultural fields for two seasons after construction to ensure the integrity of the ditch and field flow characteristics. 4.2 Pipeline and Site Maintenance and Repair EnCana's pipelines will be built to current standards of engineering, inspection, and cathodic protection and will require minimal maintenance. Repairs required because of minor corrosion and slight extemal mechanical damage to pipe and coating material can be made without interruption or with minimum interruption of service. Repairs are usually made under a reduced pipeline pressure and require a minimum amount of excavation and heavy equipment. Other minor repairs include correction of erosion, repairs to waterbars, replacement of pipeline markers, and removal of debris from the right-of-way. These repairs may require earth -moving equipment and hand tools. Some settling of the backfilled trench will occur, particularly after the first winter following construction. In this case, subsidence and potholes will be filled and the surface restored to normal grade and reseeded. If subsidence is discovered in subsequent years, the potholes will be filled and the surface restored to normal grade and reseeded. EnCana will also maintain the right-of-way in a safe, useable condition as directed by the BLM Authorized Officer or field representative. A regular maintenance program will include, but is not limited to, soil stabilization and noxious weed management and control. Pipeline failures or external mechanical damage needing major repairs may require shutdown of the pipeline. In these instances, the pipeline segment will be isolated between mainline valves and the natural gas in the segment needing repair will be vented to the atmosphere. To facilitate these repairs, equipment, tools, pre -tested pipe, and other materials for emergency use will be stored at existing operations facilities. Piceance Gathering Pipeline Project 17 March 2006 Plan of Development EnCana will be responsible for noxious weed control on disturbed areas within the limits of the right-of-way. EnCana will consult with the BLM Authorized Officer or field representative and local weed districts for acceptable weed control within the limits imposed in the grant stipulations. See the Noxious Weed Management Plan for additional information. 4.3 Vehicle and Equipment Maintenance EnCana will ensure that all operations equipment is properly maintained to reduce emissions. 4.4 Wildlife Avoidance Periods Pipeline maintenance will be scheduled to avoid wildlife construction windows as defined in the Biological Resources Protection Plan. Emergency maintenance in these areas during the wildlife construction windows will require notification of the BLM. 4.5 Survey Monuments EnCana will ensure that a registered land surveyor or a BLM cadastral surveyor restores any General Land Office or BLM cadastral survey corners/monuments obliterated during operations. Procedures to restore the monuments will be as described in the Manual of Surveying Instructions for the Survey of the Public Lands in the United States, latest edition. EnCana will record these surveys in the appropriate county and send a copy to the Authorized Officer. If the BLM cadastral surveyors or other federal surveyors are used to restore the disturbed survey monument, EnCana will be responsible for the survey cost. 5.0 TERMINATION AND ABANDONMENT OF RIGHT-OF-WAY AND FACILITIES Prior to termination of the BLM Right -of -Way Grant, or any portion thereof, EnCana will contact the Authorized Officer to arrange for a pre -termination meeting and joint inspection of the right-of-way. This meeting and inspection will take place a minimum of 30 days prior to termination, and will be held so that an agreement on an acceptable termination plan can be reached. This plan will include, but not be limited to, abandonment and/or removal of facilities, drainage structures and/or surface material, recontouring, replacing of topsoil, seeding, and monitoring. The Authorized Officer must approve the plan in writing. EnCana will relinquish all, or those specified portions, of the right-of-way in accordance with the termination plan. 18 Piceance Gathering Pipeline Project March 2006 Plan ofDevelopment—Attachment / ATTACHMENT 1 -MAPS Piceance Gathering Pipeline Project March 2006 Meeker Gas Plont Hunter Creek Station 64 Rio Blanco County Line Compressor Station RIO BLANCO COUNTY GARFIELD COUNTY Meeker 252 Regional View .0 '0 0 D o 0 0 Roan Cliff Station Parachute 30 0 3O1AWee LEGEND D COUNTY BOUNDARY AROAD im CITY AND TOWN N PROPOSED PIPELINE. $ ABOVEGROUND FACILITY 0 T 5 Wes PICEANCE GATHERING PIPELINE.

GPO 1154 • 099 ) Form 9172-31 (June 1977) UNITED STATES DEPARTMENT OF THE INTERIOR BUREAU OF LAND MANAGEMENT F-3 - FENCE CONSTRUCTION 1. GENERAL - Using materials specified herein, Contractor shall construct fence in accordance with these specifications and detailed drawings on fence design. 2. INSTALLATION OF POSTS AND BRACES — Depth to which posts shall be placed and spacing of posts and bracings shall be as shown on drawings. Steel posts shall not be used for end panel, corner panel, gate panel, or stress panel posts. All wood posts shall be set in dug holes, except that wood line posts may be driven upon written authorization by the Contracting Officer. Steel posts shall be driven ex- cept where rock formations prohibit driving. Posts which are driven shall be free of damage when in place, and any driven post which is split, twisted, or bent, or which has a broomed top shall be removed and shall be replaced with an undamaged post. When wood posts are to be set in dug holes, holes for posts shall be dug to depth at which posts ate to be set and of sufficient diameter to allow setting posts with adequate open space around each post to permit tamping of backfill for full depth of hole. Space around each post shall be filled gradually and uni- formly with soil and packed firmly from bottom of hole to ground surface. Except where rock formations prohibit, steel posts shall be driven into ground to depth shown on draw- ings or until anchor plate is slightly below ground surface. If rock formations prohibit driving of steel posts, holes of the approximate diameter of steel posts and eighteen (18) inches deep shall be exca- vated or drilled for placement of posts. Post shall then be placed in hole and grouted, if necessary, to make post solid. All posts /Shall be set in accurate alignment. .drca.,4 a Where rock or other unusual conditions make setting of posts in accordance with above two paragraphs impractical, Contractor may reauest, in writing, use of fi ur s and rock •acks for line posts in specif- ic locations. Where such request is granted by Con- tracting Officer, figure fours shall be used in lieu of steel posts, and rock jacks in lieu of wood posts; ex- cept that where a series of figure fours are required, a rock jack shall be substituted for every fifth figure four. Figure fours and rock jacks shall be constructed as shown on drawings. Corner post assemblies, gate post assemblies, and stress panels shall be constructed to conform with the design on drawings. Stress panels shall be con- structed on crests of all hills and at a maximum distance of eighty (80) rods apart where barbed wire only is to be used and forty (40) rods apart where woven wire is to be used. Stress panels are required at all points between which wire is to be stretched. 3, INSTALLATION OF WIRE - Wire shall be tightly and uniformly stretched and snugly stapled to wood posts and attached to steel posts with standard wire clips. In stretching wire, excessive tension shall be avoided. Staples shall be driven into wood until staple comes in contact with wire against post, but not tight enough to crimp wire or prevent free move- ment of wire between post and staple. Staples shall not be driven parallel to grain of wood. Woven wire shall be attached to posts at top and bottom wires and at a minimum of two intermediate horizontal wires. Fence fabric and barbed wire shall terminate at each/ end post, gate post, corner post, and stress panel.' Each line of barbed wire and each longitudinal wire o fence fabric shall be wrapped around post and spliced to itself with at least four (4) turns. When wire stays are used, they shall be uniformly spaced between adjacent posts and inserted in suc- cessive fence wire strands in such a manner that proper wire spacing will be maintained throughout length of fence. If wood stays are used, they shall be uniformly spaced between adjacent posts and shall be securely fastened to each fence wire by means of smooth wire ties in such a manner that proper wire spacing will be maintained throughout. Where fence crosses depressions, dips, swales, or other low areas and ground between adjacent posts is more than twenty (20) inches below bottom wire of a barbed wire fence or ten (10) inches below bottom strand of a woven wire fence, an additional strand or strands of barbed wire shall be stretched between successive posts or entire fence shall be weighted down with a rock deadman. Rock deadmen shall weigh a minimum of fifty (50) pounds per fence panel and shall be sufficiently heavy to keep wire from pulling posts from ground. Fence wire strands shall be anchored to deadmen with two or more strands of No. 9 galvanized wire attached to each fence strand to maintain proper spacing. 4. GATES — Wire gates shall be constructed where designated by Contracting Officer. Number of gates required is stated under Description of pork in the Specification Supplement. Gates -- and posts and braces on ends of fence on each side of gates -- will be of size and design shown on drawings. Gates shall have same type wire and same wire spacing as rest of fence. Gates shall be constructed with wood stay ends, with two wood stays equally spaced between. One gate end shall be fastened stationary to end post with three (3) nine (9) gauge wire ties, one near top, one at midpoint, and one near bottom of end stay. Opening end shall be provided with nine (9) gauge smooth wire loops at top and bottom of end stay as is common practice for fastening wire gap gates. Each gate shall also be equipped with a mechanical gate closing device as specified in Paragraph D in Form 9172-28 (F—S—Fence Construction Specifications Supplement). Immediate gate stays shall extend a minimum of three (3) inches above top fence wire and six (6) inches below bottom wire. Intermediate stays shall be approximately two (2) inches in diameter. End stays shall be approximately three (3) inches in diameter. 5.

(EnCana) and its contractors (Contractor) to avoid or minimize adverse impacts to biological resources during construction, operation, and maintenance activities. Measures identified in this plan apply to work within the project area defined as the right-of-way, access roads, temporary use areas, and other areas used during construction of the project. EnCana and Contractor personnel are to be thoroughly familiar with this plan and its contents prior to initiating construction on the project. 1.1 Purpose This plan was developed as the implementing document for relevant mitigation measures contained in the Environmental Assessment. This plan identifies protection measures that will be implemented to avoid and reduce short- and long-term impacts to biological resource habitats and populations within and adjacent to the construction workspace. Due to pending surveys in the spring of 2006, the list of construction timing restrictions (included in Attachment 1) is subject to revision, based on the results of surveys and agency coordination. This plan will updated after spring surveys and prior to construction in 2006. 2.0 RESPONSIBILITIES 2.1 EnCana EnCana will be responsible for meeting the goals and objectives of this plan and for monitoring construction activities to ensure that the Contractor applies the measures and complies with the natural resources construction constraints. EnCana will be responsible for all mandated pre - construction raptor and threatened, endangered, and sensitive plant surveys, identifying and marking sensitive areas, and marking appropriate buffer areas. EnCana is responsible for updating this plan prior to construction of the project 2.2 Contractor The Contractor will be responsible for adhering to biological resource construction timing restrictions. These are provided in Attachment 1 and described in Section 3.0. 3.0 PROTECTION MEASURES In order to avoid long-term impacts to key wildlife and plant species, protection measures have been developed in coordination with the Bureau of Land Management (BLM) and the Colorado Division of Wildlife (CDOW). Piceance Gathering Pipeline Project March 2006 Biological Resources Protection Plan 3.1 Seasonal Limitations and Buffer Zones The Environmental Assessment specifies a number of seasonal limitations and required buffer zones for sensitive resources. A seasonal limitation is defined as the time of year when no construction disturbance is allowed in a particular sensitive area. These limitations also are referred to as seasonal closures or construction constraints. Buffer zones are disturbance -free areas surrounding a sensitive location (e.g., raptor nest, sage grouse lek). Timing restrictions for those species potentially affected by the project are described below and summarized by milepost in Attachment 1. Currently, the site-specific timing restrictions for the following resources are included: • mule deer severe winter range • Greater sage grouse production areas • Greater sage grouse lek areas • Greater sage grouse winter range • nesting raptors (historic) Site-specific constraints for active raptor nests and active migratory bird nests will be added after completion of spring surveys. 3.2 Pre -Construction Surveys Field surveys are required to ensure that the project does not jeopardize the continued existence of a listed or proposed plant or animal species. Surveys required prior to construction activities are threatened, endangered and sensitive plant surveys, nesting raptor surveys, and Greater sage grouse presence and habitat surveys. No construction activities will occur until approved in writing by the BLM Authorized Officer. 3.3 General Protection Measures In addition to the site-specific seasonal limitations and buffer zones identified below, EnCana will comply with the following plant and wildlife protection measures. • Site-specific mitigation plans will be developed with the FWS for any impacted threatened or endangered species. • All non-essential access roads will be closed along the operational right-of-way to minimize disturbance impacts to wildlife. • EnCana will notify the BLM in the event of emergency maintenance. • Construction will not proceed in restricted areas until final clearance is obtained by the applicable federal and state agencies. This restriction applies to sage grouse and raptor surveys scheduled for 2006. Once final clearances have been obtained, EnCana's Environmental Manager will notify EnCana's Project Manager in writing. 2 Piceance Gathering Pipeline Project March 2006 Biological Resources Protection Plan 3.4 Greater Sage Grouse Protection Measures EnCana will comply with the following greater sage grouse protection measures: • Conduct sage grouse presence surveys, habitat assessment, and review of historical lek sites each spring prior to construction. BLM-approved biologists will be required to meet with BLM biologists prior to initiating surveys, and will conduct the surveys using BLM survey protocols. • Avoid surface disturbing activities between March lm and May 31s` in sage grouse lek areas, April 15th and July 7th in sage grouse production areas, and December 16` and March 15th in winter range. Leks and production areas are present between mileposts 8.0 and 27.3 and winter range is present between mileposts 8.0 and 23.0. Timing restrictions may be adjusted based on results of pre -construction surveys. • Seed disturbed areas with a seed mix designed to reestablish sagebrush and forb species. Sagebrush used for reseeding will be collected from local species. Distribution of sagebrush will be dependent upon range site (i.e., Arternesia tridentata spp. vaseyana and spp. wyomingensis). Reclamation on these sites will use seed mixes and seeding methods that include and promote successful establishment of full complement of grasses and favored native forbs. The following forbs will be included in reclamation seed mixes as appropriate throughout sage grouse range on lands administered by the BLM WRFO and it is recommended that these components be applied to fee -lands under EnCana's control or lease: 1) scarlet globemallow, 2) Utah sweetvetch, 3) arrowleaf balsamroot, 4) Lewis flax, and 5) Rocky Mountain penstemon. Seed mixes are provided in the Reclamation Plan. • Additional vegetation clearing to enhance sage grouse habitat will be negotiated between the BLM and the CDOW. If habitat along the existing right-of-way and the surrounding area is determined to be unsuitable due to advanced vegetation succession (e.g., pinyon -juniper regeneration, encroaching serviceberry, etc.), expansion of vegetation removal will be applied along the right-of-way to reclaim a larger area of suitable cover for sage grouse. Where possible, the proposed right-of-way will be shifted to maximize clearing of encroaching vegetation. These areas will be identified during pre -construction sage grouse habitat surveys. • Establish and maintain permanent enclosures on each of the mid- and high -elevation sage grouse habitat intervals. Enclosures will be established as a means of determining the ultimate success of forbs in the reclamation seed mix and will be designed to exclude cattle and wild horses, with dimensions of 100 feet paralleling the right-of-way and a width that spans the fully authorized temporary construction right-of-way. The location of these structures would be subject to approval of the BLM Authorized Officer. The general location on BLM lands is milepost 23.0 and 24.0 (mid -elevation sage grouse habitat). The BLM requests that, in the interest of sage grouse conservation, EnCana arrange to establish a similar enclosure on private lands in the high elevation segment south of milepost 22.0. Piceance Gathering Pipeline Project 3 March 2006 Biological Resources Protection Plan 3.5 Big Game Protection Measures EnCana will comply with the following big game protection measures: • Avoid construction activities in severe mule deer winter range between December 1st and April 30th between mileposts 34.5 and 44.5. • Install wildlife crossovers (trench plugs) with ramps on either side at maximum 1 -mile intervals and at well-defined livestock and wildlife trails to facilitate passage of big game across the trench and to prevent big game from becoming trapped in the trench. • Seed disturbed areas as discussed in the Reclamation Plan. • Redistribute large, woody material salvaged during clearing operations on BLM WRFO- administered lands. Disperse materials over the portion of the right-of-way from which the trees and brush were originally removed to meet fire management objectives and to provide wildlife habitat, seedling protection and a deterrent to vehicular traffic. Woody materials dispersed across the right-of-way will not exceed 3 to 5 tons/acre. Excess woody materials may be mulched or made available for firewood or fenceposts. 3.6 Migratory Bird Protection Measures EnCana will comply with the following migratory bird protection measures: • Conduct pre -construction migratory bird surveys each spring prior to construction to identify active nests within the project area. BLM-approved biologists would be required to meet with BLM biologists prior to initiating surveys, and would conduct the surveys using BLM survey protocols. • Implement standard nest avoidance, timing restrictions, and/or additional mitigation measures for nests located on or adjacent to the right-of-way. The FWS would be consulted with if any special status species nests were discovered on or adjacent to the right-of-way. 3.7 Raptor Protection Measures EnCana will comply with the following raptor protection measures: • Conduct pre -construction nesting raptor surveys in the spring prior to construction. BLM- approved biologists would be required to meet with BLM biologists prior to initiating surveys and would conduct the surveys using BLM survey protocols. Surveys will be conducted in suitable nesting habitat (mature pinyon -juniper woodland) for all accipiter species. In areas where the proposed pipeline corridor parallels existing disturbance, surveys will be conducted 300 feet from the edge of the right-of-way. In areas where the proposed right-of-way does not parallel an existing disturbance (i.e., a deviation), surveys would be conducted within 2,000 feet from the edge of the right -of - 4 Piceance Gathering Pipeline Project March 2006 Biological Resources Protection Plan way for the portion of pinyon -juniper habitat being dislocated from the stand by the pipeline corridor and 300 feet from the edge of the right-of-way for the stand portion of the habitat. Surveys would be completed when the birds are either on eggs or when chicks are present. Construction activities would be prohibited within 0.25 -miles of active nests between February Et and August 15th or until fledging and dispersal of the young. Spring 2005 surveys identified active nests at mileposts 11.8, 12.6, 13.1, 20.4, 37.8, and 40.0. - Surveys will be conducted in suitable nesting habitats within 1 -mile of the proposed project for cliff nesting species. Construction activities would be prohibited within 0.25 - miles of active nests between February 1st and August 15th or until fledging and dispersal of the young. 3.8 Threatened, Endangered and Sensitive Raptor Protection Measures EnCana will comply with the following threatened, endangered, and sensitive raptor protection measures: • Conduct pre -construction surveys, each spring prior to construction, to identify active goshawk nests present near or adjacent to the construction right-of-way. BLM-approved biologists will be required to meet with BLM biologists prior to initiating surveys, and will conduct the surveys using BLM survey protocols. Construction activities will not occur within 0.5 -miles of active goshawk nests between February l' and August 15th or until fledgling and dispersal of the young. • Consult with the FWS to determine appropriate protection measures if any federally listed or candidate raptor species are identified during pre -construction surveys. 3.9 Threatened, Endangered and Sensitive Plant Protection Measures EnCana will comply with the following threatened, endangered, and sensitive plant protection measures: • Avoid plants that occur along the outside edge of the right-of-way and installing exclusion fencing to prevent disturbance from construction activities. Fence will be installed along the edges of the right-of-way in the Ryan Gulch Area of Critical Environmental Concern (ACEC) between milepost 42.6 and 43.4. • Seed disturbed areas with Standard WRFO Seed Mix. 3.10 Discovery During Construction If a species of concern is discovered during construction that was not discovered during pre - construction surveys, the BLM will be notified immediately, and the necessary procedures will be implemented.

(EnCana) and its contractors (Contractor) to ensure that blasting operations are carried out in accordance with federal, state, and local regulations and restrictions. Measures identified in this plan apply to work within the project area defined as the right-of-way, access roads, temporary use areas, and other areas used during construction of the project. EnCana and Contractor personnel are to be thoroughly familiar with this plan and its contents prior to initiating construction on the project. 1.1 Purpose The project crosses numerous areas of surface and subsurface rock where mechanical equipment may be unable to rip or excavate rock from the right-of-way or trenchline to allow construction of the pipeline. In these areas, blasting will be used to shatter the rock to allow grading of the right-of-way for access or excavation of the trenchline to provide an adequate depth of cover to protect the pipeline. This plan describes safety standards and practices that will be implemented during construction to minimize health, safety, and environmental concerns related to blasting on the project. This plan was developed as the implementing document for relevant mitigation measures contained in the Environmental Assessment. 2.0 BLASTING PROCEDURES The following procedures will be implemented by the Contractor during blasting operations on the project. This section of the plan describes pre -blasting requirements, the typical sequence of activities associated with blasting operations, notifications required by the Contractor and EnCana, and areas where blasting is restricted or where special mitigation measures will be required. 2.1 Pre -Blasting Requirements 2.1.1 Regulations and Restrictions The Contractor will obtain all necessary permits for, and will comply with, the rules and regulations of the Occupational Safety and Health Administration (OSHA) and all federal, state, county, and local regulations and permits for the use, storage, transportation, and handling of explosive materials. The Contractor will provide EnCana with copies of all required permits prior to commencing blasting operations. 2.1.2 Explosives Storage The Contractor will obtain necessary permits and comply with all conditions of 27 CFR 55 governing the storage of explosives. All powder magazines will be located in a secure remote Piceance Gathering Pipeline Project March 2006 Blasting Plan area and will be kept locked. Powder and detonators will never be stored together in the magazine, and any vehicle used to transport explosives from the magazine to the blast site will conform to applicable federal and state regulations. Magazines located on BLM land must be approved by the Authorized Officer. As required by federal statutes, the Contractor will maintain an inventory and use record for all explosives and detonating caps that will be reconciled at the end of each working day, and will include the number of misfires and their disposition. The inventory and use record will be available for inspection by EnCana and jurisdictional authorities at all times. 2.1.3 Contractor Blasting Procedure Qualification Only workmen thoroughly experienced in handling explosives will be permitted to supervise, handle, haul, or detonate explosives. In jurisdictions where the licensing of blasters is mandatory, the Contractor will provide EnCana with proof of the required certification for every person directing or conducting blasting operations. In no instance will the Contractor allow a person to conduct or direct a blasting operation unless that person is the holder of a valid Blaster's Certificate, where required by the authority having jurisdiction. The Contractor will utilize a qualified engineer to assist in the preparation of site-specific blasting procedures and to provide an engineering report showing recommended charges and blasting methods to be used at specific locations. Contractor's written blasting procedures must be submitted and approved by EnCana before commencing blasting. The Contractor will qualify its blasting procedure with EnCana prior to commencing blasting operations. The procedure qualification will include a minimum of five test shots not exceeding 20 feet each in length, monitored with three -channel seismographs. Data from the test shots will be used by the Contractor to establish standard shot in terms of pounds of explosive per delay. Test shots are required for each major change in geology, explosive manufacturer, or explosive grade, as determined by EnCana. Production shot procedures and delays will be identical to the test shot procedures and delays. 2.1.4 Notifications The Contractor must notify EnCana and appropriate federal, state, county, and local agencies at least 48 hours prior to storing or using explosives on the right-of-way. In addition, the following notifications will be needed throughout the project. • Prior to any detonation of explosives in the vicinity of existing facilities (such as pipelines, dwellings, structures, overhead or underground utilities, farm operations, or public crossings), a minimum of 48 hours notice will be given to EnCana, the appropriate authorities, and the owners or operators of any facilities that may be affected by the blasting. The Contractor will also comply with the "One Call" notification requirements, if available. • Nearby fee -landowners will be notified by EnCana 24 hours (the Contractor will give EnCana 48 hours notice) in advance of blasting to ensure that all persons, livestock, and equipment are out of the danger zone. Blasting will not be used where there are 2 Blasting Plan identifiable risks due to the proximity of residences or other structures. 2.2 Blasting Process The following section provides a brief overview of the typical sequence of activities associated with blasting operations. • Trenchline Stripping—The trenchline or right-of-way where blasting will be required, is stripped of soil to expose the rock that cannot be excavated. • Drilling—Holes are drilled in the rock with pneumatic drills to allow insertion of the explosive charge. Holes are drilled in a pre -determined pattern in order to control the blast and fly -rock as appropriate. Signs are installed at the limits of the blast area noting blasting signals, access, and radio restrictions. • Loading—Holes are loaded with explosives and are filled with sand or soil to contain the blast within the trenchline. (Previously conducted tests on charges and drill patterns determine the appropriate combination of explosive charge and drill pattern for a particular geologic area that will provide adequate fracturing of the rock, and appropriate control of air blast, vibrations, and fly -rock.) • Padding/Matting—Soil padding or blasting mats will be placed over the blast area to control fly-rock/debris, when in close proximity to structures. The Contractor's blasting procedure and test shots will adequately address and confirm acceptable fly -rock parameters. Topsoil will not be used as padding. • Warning—The blaster examines the blast area to ensure that vehicles and personnel have withdrawn to a safe distance. Access through the area is restricted and a series of "blast imminent" waming signals are sounded. • Blast—Following the warning signals, the explosives will be detonated. • Clearance—The Contractor's blasting foreman or blaster will conduct a thorough post - blast inspection of the blast area for cut-offs or misfires and will ensure that any undetonated explosives are properly destroyed by detonation prior to any other work proceeding. Once the area is verified clear of unexploded charges and hazards such as falling rock, the "all clear" signal is given. 2.3 Restrictions No blasting will be done without prior approval of EnCana. The Contractor will be liable for any and all damages resulting from blasting operations. Special blasting controls will be required in the vicinity of power lines, telephone lines, fiber optic lines, existing pipeline facilities, structures, water wells, springs, or buildings or where directed by EnCana to preclude the possibility of damage due to fly -rock, shock waves, vibrations, or changes to hydraulic Piceance Gathering Pipeline Project 3 March 2006 Blasting Plan conductivity of the bedrock near important springs and wells. This will be accomplished by a combination of blast design, adequate collaring, and matting. Matting to control fly -rock includes, but is not limited to, fabricated mats, overburden, and sand -pad matting. Fly -rock leaving the right-of-way will be collected immediately and either returned to the right-of-way or disposed of at disposal sites approved by EnCana, the BLM, or fee -landowners. 3.0 SAFETY MEASURES Standard safety measures will be employed during blasting operations to prevent damage to adjacent resources, residences, utilities, and roadways. As discussed above, these measures will include blasting controls to limit fly -rock, air blast, and vibrations near sensitive areas. Warning signals, signage, and procedures to protect human health and safety are discussed below. 3.1 General Safety Requirements The Contractor will at all times protect its workers and the public from any injury or harm that might arise from drilling dust and the use of explosives. Only workers thoroughly experienced in handling explosives will be permitted to supervise, handle, haul, load, or shoot explosives. In those jurisdictions where the licensing of blasters is mandatory, the Contractor will provide EnCana, before any crew assignment, with proof of the required certification for every person so required. The Contractor will not leave loaded holes overnight, unattended, or unprotected. Explosives will only be primed immediately before use. Loading and blasting will be concluded by 4:00 p.m. each work day, unless prior approval is received from EnCana. No explosives or blasting agents will be abandoned on the right-of-way. During the blasting procedure, all personnel not involved in the actual detonation will stand back at least 1,000 feet and workers involved with the detonation will stand back at least 650 feet from the time the "blast imminent" signal is given until the "all clear" has been sounded. The Contractor will post flagmen on all roadways passing within 1,000 feet of the blast area to stop all traffic during blasting operations. 3.2 Warning Signs and Signals 3.2.1 Signs and Access Control The Contractor will post warning signs and guards at all points of access to the blasting area, including trails. The warning signs will comply with the requirements of the jurisdictional authorities and will have lettering a minimum of 4 inches in height on a contrasting background. Signs will be installed at the limits of the blast area noting warning signals, and access and radio restrictions. All access roads to blasting sites will be blocked off and signed while blasting operations are taking place. Flagmen and/or guards will be posted at all roadways, trails, construction roads, or other access points to the blast area, within 1,000 feet from the blast site in every direction. 4 Blasting Plan 3.2.2 Blast Site Clearance Prior to initiating the blast warning system, the blaster will: • complete the blast inspection, • clear all personnel not involved with blasting operations from the blast area for a distance of at least 1,000 feet, • ensure that all right-of-way traffic and, if applicable, road and access road traffic is halted, • confirm that the guards are posted and the controlled area is secure, and • retreat to a safe firing distance. 3.2.3 Blast Signals The Contractor will use an acceptable air horn or siren to give the proper blasting warning and "all clear" signals. The warning system used for blast signals will produce a sound (air horn or siren) that is distinct from any other signals used on construction. Use of vehicle horns as blast signals is not permitted. The following audible blast warning system will be employed: • Blast Imminent—Three minutes before the blast is to be detonated, the blaster will give three short blasts of the air horn or siren. If there is an interruption to the blast routine once the "Blast Imminent" signal has been given, the entire blast signal procedure will begin again. • Blast Signal—Three minutes after the "blast imminent" signal has been given, the blaster will give one short blast of his air horn or siren, followed by detonation of the explosives. • All Clear Signal—The blaster will check the blast site to ensure that all charges have detonated. Once this assessment has been confirmed, the blaster will give one long blast of the air horn or siren. 3.3 Fire Safety The presence of explosive materials on the project site could potentially increase the risk of fire during construction. To reduce this risk, the Contractor will strictly adhere to all requirements of the Fire Prevention and Suppression Plan. In addition, special precautions related to blasting operations include: • Prohibit ignition devices or sources within 50 feet of an explosives storage area. • Maintain magazine sites so that they are clear of fuels and combustible materials, and that the structures are well -ventilated and fire resistant. • Protect magazines from wildfires that could occur in the immediate area (this will be accomplished by removing all vegetation within 50 feet of the storage container). • Remove empty explosive storage boxes from the right-of-way and disposing of at a project approved disposal site.

(EnCana) and its contractors (Contractor) to avoid or minimize adverse impacts to cultural resources during construction and subsequent reclamation, restoration, and maintenance activities. Measures identified in this plan apply to work within the project area defined as the right-of-way (ROW), access roads, temporary use areas, and other areas used during construction of the project. EnCana and Contractor personnel are to be thoroughly familiar with this plan and its contents prior to initiating construction on the project. 1.1 Purpose The purpose of this plan is to provide for the identification, evaluation, and treatment of cultural resources that may be impacted as a result of construction of the project. This plan also defines the responsibilities and measures to preserve and protect cultural resources during construction of the project. This plan was developed as the implementing document for relevant mitigation measures contained in the Environmental Assessment. 2.0 RESPONSIBILITIES 2.1 EnCana EnCana will employ standard operating procedures during construction to protect cultural resources. EnCana will: • Provide cultural monitoring by professional archaeologists during construction for project areas determined to be sensitive for cultural resources. • Include specific language in the Contractor's specifications regarding trespass on sites and procedures to be followed during unexpected discovery. • Use procedures described in Sections 4.0 and 5.0 to deal with the inadvertent exposure of cultural resources during construction. 2.2 Contractor The Contractor will be responsible for following the project procedures and requirements defined in this plan during and after the exposure of cultural resources. The Contractor will be responsible for providing EnCana's Environmental Inspector with adequate advance notification of construction activities so that archaeological monitors can be deployed where required. If, in its operations, the Contractor damages, or is found to have damaged, any previously Piceance Gathering Pipeline Project March 2006 Cultural Resources Protection Plan documented or undocumented historic or prehistoric cultural resources, EnCana agrees to have a permitted cultural resources consultant prepare and execute a BLM-approved data recovery plan. 2.3 Environmental Inspector EnCana's Environmental Inspector will monitor daily construction activities, and is responsible for ensuring pipeline construction activities comply with all applicable mitigation requirements, permit conditions, and environmental specifications relating to cultural resources protection. This includes keeping track of construction activities and ensuring that monitors will be onsite when construction activities require cultural monitoring. 3.0 PRE -CONSTRUCTION ACTIVITIES 3.1 Testing Sites field evaluated and recommended for listing on the National Register of Historic Places (NRHP) will be tested prior to construction. Testing plans will be approved by the BLM Authorized Officer prior to surface disturbance. 3.2 Training The Contractor will inform all crews of requirements relating to cultural resource protection. All construction personnel who operate ground -disturbing equipment will receive special instruction on the types of archaeological remains that may be encountered and the procedures to be followed if they encounter buried archaeological deposits or features. All construction and other employees present on the right-of-way will be informed of both the Environmental Inspector and Cultural Monitor's authority to halt work. All personnel will be informed that they are subject to prosecution for knowingly disturbing historic or prehistoric sites, or for collecting artifacts. Violation may result in removal from the project and/or may result in civil or criminal penalties in accordance with the Archaeological Resources Protection Act of 1979 (as amended). 4.0 MONITORING AND REPORTING REQUIREMENTS Cultural resource monitoring will be conducted by Cultural Monitors to ensure that aboriginal and historic cultural materials are preserved and to ascertain whether construction may continue after the unexpected discovery of any cultural materials. 4.1 Monitoring Cultural Monitors will monitor project construction through all significant sites. No ground disturbing construction activities (topsoiling, grading, or ditching) will begin prior to their arrival. The Contractor is responsible for notifying EnCana's Environmental Inspector at least 72 hours in advance of areas requiring monitoring where identified on the following table, so that archaeological monitors can be deployed where required. The Contractor will be responsible for all construction delays due to insufficient notification. Areas requiring cultural monitoring are 2 Piceance Gathering Pipeline Project March 2006 Cultural Resources Protection Plan included in Attachment 1. Archaeological monitoring will consist of the examination of all heavy equipment ground disturbances (clearing, grading, and trenching) within 100 feet of a significant site, especially trench walls and the surfaces of graded areas. Cultural monitoring will be conducted in two phases: • Phase One—The first phase will involve monitoring of the construction zone after vegetation clearing has occurred but prior to grading (including topsoiling) activities. The Cultural Monitor will follow the grading equipment looking for indications of shallowly buried cultural materials. • Phase Two—The second monitoring phase will occur during pipeline trenching. The Cultural Monitor will follow the ditching equipment at a cautionary distance, allowing time for construction dust to settle and for visible detection of buried cultural features. 4.2 Reporting Cultural Monitors will document daily monitoring activities on daily monitoring report forms that will be delivered to the Environmental Inspector on a daily basis. Cultural monitoring results will be reported on a bi-weekly basis to the BLM Authorized Officer in a short letter report. 5.0 DISCOVERY REQUIREMENTS 5.1 Cultural Resources If cultural resources (artifacts, hearths, rock art, etc.) are discovered during construction, the Contractor will immediately stop all work near the discovery. The following steps will be implemented when cultural resources are discovered: • Cease all earth disturbing activity within 100 feet of the discovery. The area will be secured until notified to proceed from the BLM Authorized Officer. • Contact the BLM Authorized Officer, Environmental Inspector, and Cultural Monitor immediately. At the direction of the BLM, the Cultural Monitor will assess the nature of the discovery and determine the necessary course of action. If necessary, the Cultural Monitor will mark the area and recommend procedures to be implemented to avoid further site damage. EnCana will protect the discovery until removed. The BLM Authorized Officer will, within five working days, inform EnCana as to: - whether the materials appear eligible for the NRHP, - mitigation measures required before the site can be used (assuming in situ preservation is Piceance Gathering Pipeline Project 3 March 2006 Cultural Resources Protection Plan not practicable), and - a time frame for the BLM Authorized Officer to complete an expedited review to confirm, through SHPO, that the findings of the BLM Authorized Officer are correct and mitigation is appropriate. 5.2 Human Remains If human remains are discovered during construction, the Contractor will be responsible for immediately stopping all work near the discovery. The following steps will be implemented when human remains are discovered: • Cease all earth disturbing activity within 100 feet of the discovery. The area will be secured until notified to proceed from the BLM Authorized Officer. • Contact the BLM Authorized Officer, Environmental Inspector, and Cultural Monitor, along with the relevant county coroner or sheriff, immediately. The BLM will notify the SHPO, as appropriate. • Allow the Cultural Monitor to assess the nature of the discovery and determine the necessary course of action. If necessary, the Cultural Monitor will mark the area and recommend procedures to be implemented to avoid further site damage. EnCana will protect Native American remains and objects until removal. It may be necessary for EnCana to provide 24- hour, onsite security as determined by the BLM. • Report any funerary or associated funerary objects encountered during construction activities immediately to the BLM. Activities will cease in the immediate area of the discovery and the discovery will be protected for 30 days or until notified to proceed by the BLM Authorized Officer. 4 Piceance Gathering Pipeline Project March 2006 Cultural Resources Protection Plan—Attachment / ATTACHMENT 1 -MONITORING LOCATIONS Piceance Gathering Pipeline Project March 2006 Cultural Resources Protection Plan Attachment 1 (Will be provided prior to construction.)

(EnCana) and its contractors (Contractor) will implement to construct and operate the project in compliance with all federal, state, and local permits and requirements. Measures identified in this plan apply to work within the project area defined as the right-of-way, access roads, temporary use areas, and other areas used during construction of the project. EnCana and Contractor personnel are to be thoroughly familiar with this plan and its contents prior to initiating construction on the project. 1.1 Purpose EnCana is committed to designing, constructing, and operating the project in an environmentally sound manner and in compliance with all local, state, and federal regulations. The project will be designed and planned to protect environmental resources to the greatest extent practicable. The primary purpose of this plan is to outline procedures and protocols for managing environmental compliance during construction of the project. The environmental compliance program will be implemented under the direction of the Bureau of Land Management. The purpose of the environmental compliance program is to monitor and document the implementation of mitigation measures included in the Environmental Assessment. The following strategies have been adopted as the framework of the environmental compliance management program. Environmental Training: Environmental training programs will be conducted prior to construction to support compliance with environmental requirements. All project personnel working on the right-of-way will attend environmental training. Environmental Inspection: The EnCana Environmental Inspector (El) will have a visible presence on the project. During construction, the EI will observe and document environmental compliance, as well as actively identify and anticipate potential environmental compliance concerns ahead of construction. Clear and Responsive Communication: Environmental and construction representatives will interact daily and will ensure that all verbal discussions and written documentation are professional and responsive at all times. All project personnel will interact as frequently as necessary to ensure that environmental information, concerns, and issues requiring resolution are communicated in a timely manner. Teamwork: In the event of a reoccurring or significant environmental non-compliance, relevant project representatives (construction, engineering, lands, environmental) will work jointly to develop and implement responsive resolutions as efficiently as possible. Piceance Gathering Pipeline Project March 2006 Environmental Compliance Management Plan 2.0 RESPONSIBILITIES The environmental compliance management roles and responsibilities are summarized below. 2.1 EnCana 2.1.1 Project Manager The Project Manager will: • Coordinate among the Chief Construction Inspector and Environmental Manager. • Consult with the appropriate agencies on changes of project work that affect the mitigation program or sensitive resources. • Act as the arbitrator between construction and environmental considerations if an internal conflict arises. 2.1.2 Environmental Manager The Environmental Manager is the ultimate authority for project environmental compliance and successful implementation of the environmental compliance management program. Responsibilities include policy and management level communications with EnCana management, and federal, state, and local regulatory agencies. The Environmental Manager will: • Communicate frequently with the Environmental Inspector, Chief Construction Inspector, and the Contractor regarding environmental inspection and compliance activities. • Maintain communication with regulatory agencies. • Ensure that spring biological surveys are completed and the Biological Resources Protection Plan has been updated and approved by the BLM prior to construction. • Interface with and advise project management regarding environmental compliance. • Report hazardous material spills in accordance with the Spill Prevention, Containment, and Countermeasure Plan. • Coordinate with various project representatives, as necessary, to resolve issues when performing project troubleshooting on environmental compliance issues. 2.1.3 Environmental Inspector An Environmental Inspector (El) will be assigned to oversee the environmental compliance inspection process. In addition to performing inspection duties, the EI will: • Communicate with the Environmental Manager and the Chief Construction Inspector on a 2 Piceance Gathering Pipeline Project March 2006 Environmental Compliance Management Plan daily basis. • Provide key liaison role in coordinating attendees and facilitating agreements in the field, as appropriate, with agency representatives. • Coordinate daily with construction inspectors, the Contractor, and biological, cultural, and paleontological monitors to ensure that required monitors are present when construction activities are scheduled in all areas requiring monitors. The EI will directly represent the BLM and will have authority to enforce the environmental requirements of the Plan of Development and any environmental permits. The EI will be on a peer status with other project construction inspection staff. The EI will act as a liaison between the Contractor and agency field representatives and will coordinate regularly with the various construction inspectors to ensure that the construction inspectors are apprised of the status of environmental issues in their respective areas. The EI will be responsible for determining non-compliance activities and anticipating activities and situations that could result in non-compliance to Plan of Development, environmental permits, and project stipulations contained in the BLM Right -of -Way Grant. The EI will play a significant role suggesting methods to bring construction activity into compliance and/or to temporarily halt certain activities that may cause damage to sensitive environmental resources. In this capacity, the EI will work in conjunction with the Construction Inspector as applicable. The EI will use sound professional judgment in exercising these authorities and will not stop work unless there is a situation that could: • cause serious injury or harm to persons or property; • harm threatened endangered or sensitive species or protected cultural resources; or • violate certain federal or state codes. 2.1.4 Chief Construction Inspector The Chief Construction Inspector will: • Notify the Environmental Manager of changes in the project work so that appropriate environmental reviews can take place. • Work with the Environmental Inspector to evaluate and improve the implementation of the environmental compliance management program, as construction progresses; • Coordinate with the Contractor, Environmental Inspector, and construction inspectors for all construction -related issues. • Supervise compliance with construction, safety, and environmental mitigation measures identified in the Plan of Development. Piceance Gathering Pipeline Project 3 March 2006 Environmental Compliance Management Plan 2.1.5 Construction Inspectors Construction inspectors will: • Conduct quality control construction inspections within area of expertise. • Provide support in monitoring and reporting compliance with the environmental compliance management program. 2.1.6 Threatened, Endangered, and/or Sensitive Species Monitors At this time there are no requirements for Threatened, Endangered, or Sensitive Species (biological) Monitors on the project. If biological monitors are required as a result of spring survey findings, the biological monitors will be present in areas requiring biological monitors as listed in the Biological Resources Protection Plan. Biological monitors will: • Monitor biological resources. • Observe construction activities, document work, and submit reports to the Environmental Inspector. 2.1.7 Cultural Resource and Paleontological Monitors Cultural and paleontological monitors will be present in areas requiring monitors as listed in the Cultural Resources Protection Plan and the Paleontological Resources Protection Plan. Cultural and Paleontological monitors will: • Monitor cultural and paleontological resource protection areas. • Observe construction activities, documenting work, and submitting reports to the Environmental Inspector. 2.2 Contractor The Contractor will have the prime responsibility for ensuring that the project is constructed in accordance and in compliance with all federal, state, and local environmental permits, requirements, and stipulations. During construction of the project, it will be the responsibility of the Contractor to train all workers engaged on the project and keep them up-to-date regarding environmental requirements. 3.0 ORIENTATION AND TRAINING Training is an integral tool for achieving environmental compliance. An environmental training program will be developed to target every level of the organization (management and 4 Piceance Gathering Pipeline Project March 2006 Environmental Compliance Management Plan workforce). Topics to be addressed during training will include biological resources, cultural resources, erosion control, fire prevention, hazardous materials spill prevention and control measures and other project requirements. 4.0 REPORTING The EI will document Contractor conformance with project mitigation requirements, permit conditions, and environmental specifications on a. weekly basis. Reports should document project -related activities inspected, milepost and station number, date and approximate time of day, ownership (BLM or fee -lands), sensitive sites present (i.e., cultural sites, paleontological sites, waterbodies, wetlands, etc.), and a brief description of the activities observed. The EI will assign a level of compliance to each report. The compliance level will be determined by comparing the activity observed with the mitigation measures included in the Plan of Development and stipulations attached to the BLM Right -of - Way grant. The following compliance levels will be used: • Acceptable—issued when the activities observed are in compliance with the project environmental requirements. • Minor problem—issued when there is a minor deviation from the project requirements, but the deviation does not place sensitive resources at risk. An example of a minor problem would be if a small amount of soil is placed outside the approved workspace boundaries, but has no effect on biological or cultural resources. If the minor problem is not corrected within a reasonable timeframe or multiple occurrences of a similar nature occur, the situation might be elevated to a noncompliance. • Noncompliance—issued when an activity is observed that violates the project environmental requirements and places a sensitive resource at risk. Examples would include failure to install or maintain erosion control devices or lack of cultural or paleontological monitors at required locations. Compliance results will be reported on a weekly basis to the BLM Authorized Officer and EnCana representatives in a short letter report.

(EnCana) and its contractors (Contractor) to ensure that fire prevention and suppression techniques are carried out in accordance with federal, state, and local regulations. Measures identified in this plan apply to work within the project area defined as the right-of-way, access roads, temporary use areas, and other areas used during construction of the project. EnCana and Contractor personnel are to be thoroughly familiar with this plan and its contents prior to initiating construction on the project. 1.1 Purpose The risk of fire danger during pipeline construction is related to smoking, refueling activities, operating vehicles and other equipment off roadways, welding activities and the use of flammable liquids. During pipeline operation, risk of fire is primarily from unauthorized entry onto the right-of-way. During maintenance operations, risk of fire is from vehicles and pipeline maintenance activities that require welding. This plan establishes standards and practices that will minimize the risk of fire danger and, in case of fire, provide for immediate suppression. This plan was developed as the implementing document for relevant mitigation measures contained in the Environmental Assessment. 2.0 RESPONSIBILITIES AND COORDINATION EnCana and the Contractor are responsible for providing all necessary fire -fighting equipment on the project site to their respective employees and operating under the requirements of this plan. Prior to construction, EnCana will contact the appropriate authorities to establish communications, obtain permits (if applicable), and/or fulfill other obligations as directed by fire control authorities. In addition to the above, EnCana will: • Ensure prevention, detection, pre -suppression, and suppression activities are in accordance with this fire plan and federal, state and county laws, ordinances, and regulations pertaining to fire; • Accompany agency representatives on fire tool and equipment inspections and take corrective action upon notification of any fire protection requirements that are not in compliance; and The fire prevention and suppression measures described in this plan will be in effect from June 1st to the end of construction. These dates may change by advance written notice from fire control authorities. However, required tools and equipment will be kept in serviceable condition and be immediately available for fire suppression at all times. Piceance Gathering Pipeline Project March 2006 Fire Prevention and Suppression Plan 3.0 FIRE PREVENTION MEASURES 3.1 Pre -Construction and Construction Methods and procedures that will be implemented prior to and during the construction period to minimize the risk of fire are described below. 3.1.1 Training The Contractor will train all personnel about the measures to take in the event of a fire and will inform each construction crew member of fire dangers, locations of extinguishers and equipment, and individual responsibilities for fire prevention and suppression. Smoking and fire rules will also be discussed with the Contractor and all field personnel during the safety training program. 3.1.2 Smoking Smoking is prohibited except in areas cleared and graded a minimum of 10 feet in diameter to mineral soil. All burning tobacco and matches will be extinguished before discarding. Smoking is also prohibited while operating equipment or vehicles, except in enclosed cabs or vehicles. 3.1.3 Spark Arresters During construction, operation, and maintenance of the right-of-way, all Contractor and EnCana equipment operating with an internal combustion engine will be equipped with federally approved spark arresters. Spark arresters are not required on trucks, buses and passenger vehicles (excluding motorcycles) that are equipped with an unaltered muffler or on diesel engines equipped with a turbocharger. A BLM fire prevention officer will have full authority to inspect spark arresters on project equipment prior to its use on the project on federal lands and periodically during the construction project. 3.1.4 Parking, Vehicle Operation and Storage Areas In no case will motorized equipment, including worker transportation vehicles, be driven or parked outside of the designated and approved construction workspace. Equipment parking areas, the right-of-way, temporary use areas, and small stationary engine sites, where permitted, will be cleared of all flammable material. Glass containers will not be used to store gasoline or other flammables. 3.1.5 Equipment All motor vehicles and equipment will carry one long -handled (48 -inch minimum), round -point shovel and one dry chemical fire extinguisher (5 -pounds minimum). Individuals using power saws and grinders will have a shovel and fire extinguisher, as described above, immediately available. All equipment will be kept in a serviceable condition and readily available. 3.1.6 Road Closures The Contractor will notify the appropriate fire suppression agency of the scheduled closures prior to the open -cut crossing of a road. If required, the Contractor will construct a bypass prior 2 Piceance Gathering Pipeline Project March 2006 Fire Prevention and Suppression Plan to the open -cut installation of a road crossing, unless a convenient detour can be established on existing approved roads or within approved work limits. All bypasses will be clearly marked by the Contractor. During road closures the Contractor will designate one person, who knows the bypass, to direct traffic. The Contractor will minimize, to the extent possible, the duration of road closures. Additional information is provided in the Transportation Management Plan. 3.1.7 Refueling Fuel trucks will have a large fire extinguisher charged with the appropriate chemical to control electrical and gas fires. The extinguisher will be a minimum size 35 -pound capacity with 40 BC or higher rating. 3.1.8 Burning No burning of slash, brush, stumps, trash, or other project debris will be permitted on the project. No campfires, lunch fires, or warming fires will be allowed. 3.1.9 Welding One 5 -gallon backpack pump will be required with each welding unit in addition to the standard fire equipment required in all vehicles. All equipment will be kept in a serviceable condition and readily available. 3.1.10 Monitoring Construction and Environmental Inspectors for EnCana will inspect the construction workspace and the Contractor's operations for compliance with all provisions of this plan. In addition, federal, state, and local fire control agencies may perform inspections in areas under their jurisdiction at their discretion. 3.2 Pipeline Operation and Maintenance During pipeline operation, the risk of fire danger is minimal. The primary causes of fire on the right-of-way result from unauthorized entry by individuals utilizing the right-of-way for recreational purposes and from fires started outside of the right-of-way. In the latter case, the right-of-way can be used by authorities as a potential fire break. During maintenance operations, EnCana or the Contractor will equip personnel with basic fire -fighting equipment including fire extinguishers and shovels as described in Section 3.1.6. Maintenance crews will also carry fire suppression contacts as described in Section 4.0. 3.3 Aboveground Appurtenances Defensible space will be created around any aboveground appurtenances in accordance with Colorado Firewise guidelines (www.firewise.com). Piceance Gathering Pipeline Project 3 March 2006 Fire Prevention and Suppression Plan 4.0 FIRE SUPPRESSION The Contractor will take the following actions should a fire occur within the project area during construction. • Take immediate action to suppress fires using all available manpower and equipment. • Immediately notify the nearest fire suppression agency of the fire location, action taken, and status (refer to Table 4-0 Fire Suppression Contacts). • Immediately notify EnCana's Construction Inspector, Chief Construction Inspector, and Environmental Inspector of the fire location and action taken.

If the fire is uncontrolled, the Contractor will call the nearest fire suppression agency (refer to Table 4-0 Fire Suppression Contacts). Information regarding the location of the fire, property ownership, and closest access roads should be provided to the dispatch office and EnCana. If a reported fire is controlled, but not extinguished, the Contractor will call to notify the nearest fire suppression agency to alert them of the situation. The status of the fire will be monitored by the Contractor and when extinguished, the nearest fire suppression agency will be notified. 4 Piceance Gathering Pipeline Project March 2006 Fugitive Dust Control Plan Fugitive Dust Control Plan TABLE OF CONTENTS 1.0 Introduction 1 1.1 Purpose 1 2.0 Requirements for Dust Control 1 2.1 General Requirements 1 2.2 Control of Unpaved Roads On -Site 2 2.3 Control of Paved Roads 2 2.4 Control of Disturbed Areas On -Site 2 Piceance Gathering Pipeline Project March 2006 Fugitive Dust Control Plan 1.0 INTRODUCTION This Fugitive Dust Control Plan (plan) describes the general control measures to be taken by EnCana Oil and Gas (USA) Inc. (EnCana) and its contractors (Contractor) to ensure that dust suppression techniques are implemented to control fugitive dust sources during construction operations. Measures identified in this plan apply to work within the project area defined as the right-of-way, access roads, temporary use areas, and other areas used during construction of the project. Additional mitigation measures may be required and will be listed as conditions in the Colorado Department of Public Health and Environment (CDPHE) Air Pollution Control Division (APCD) Construction Emission Permit. EnCana and Contractor personnel are to be thoroughly familiar with this plan and its contents prior to initiating construction on the project. 1.1 Purpose The purpose of this plan is to identify measures to be taken by EnCana and the Contractor to control fugitive dust sources during construction operations. This plan was developed as the implementing document for relevant mitigation measures contained in the Environmental Assessment. 2.0 REQUIREMENTS FOR DUST CONTROL 2.1 General Requirements The Contractor is required to provide dust control measures for all areas disturbed by construction. The measures listed below will be required, as necessary, to.control fugitive dust. Additional measures, if required, will be listed in the CDPHE APCD Construction Emission Permit. Dust control will be implemented by the Contractor in areas of active construction within 500 feet of highways, residences, and power transmission rights-of-way (unless waived by the owner/operator). Dust control is required near major roadways any time dust stays in the air for 5 minutes or reaches 20 feet in height. Dust control is required on the construction right-of-way and access roads when dust plumes exceed 20 percent visual opacity. Dust control will also be implemented on access roads, as determined by EnCana, and as required by the Contractor for the health and safety of employees. Dust control will be achieved primarily through application of water or an approved dust palliative. Application rates for the dust palliative will follow the manufacturer's recommendations. All dust palliatives used will be biodegradable. Use of salts with water as a suppressant is limited to magnesium chloride (MC70). Water will not be appropriated from surface waters unless EnCana has appropriate water rights. Piceance Gathering Pipeline Project March 2006 Fugitive Dust Control Plan Water obtained from wells is permitted, but written approval from the fee -landowner is required prior to appropriation. 2.2 Control of Unpaved Roads On -Site During construction, operation, and maintenance of the project, the Contractor will suppress dust with application of water or other suppressant as needed and will control vehicle speed to 15 miles per hour (mph). The Contractor shall apply dust suppressants to the construction work area and access roads at the request of EnCana, the BLM, and county or state representatives. 2.3 Control of Paved Roads The Contractor will implement the following requirements on paved roads: • Construction entrances will be installed to prevent tracking mud and soil onto paved roads. Construction entrances will be constructed as required by county, state, and BLM permits. • Any soil tracked onto a paved road that extends more than 50 feet from the point of origin shall be cleaned up by the Contractor within one hour of discovery. Any soil tracked onto a paved road that extends less than 50 feet shall be cleaned up by the end of the working day. 2.4 Control of Disturbed Areas On -Site During construction, operation, and maintenance of the project, the Contractor will suppress dust with application of water or other suppressant as needed, and will control vehicle speed to 15 mph. All areas disturbed by construction will be revegetated in accordance with EnCana's Reclamation Plan. The Contractor shall apply dust suppressants to the construction work area and access roads at the request of EnCana, the BLM, and county or state representatives. 2 Piceance Gathering Pipeline Project March 2006 Noxious Weed Management Plan Noxious Weed Management Plan TABLE OF CONTENTS 1.0 Introduction 1 1.1 Purpose 1 2.0 Noxious Weed Management 1 2.1 Identification and Treatment of Problem Areas 1 2.2 Preventative Measures 2 2.3 Monitoring 2 LIST OF ATTACHMENTS Attachment 1—Noxious Weed Infestations Attachment 2—Wash Station Typical Piceance Gathering Pipeline Project March 2006 Noxious Weed Management Plan 1.0 INTRODUCTION This Noxious Weed Management Plan (plan) identifies measures to be taken by EnCana Oil and Gas (USA) Inc. (EnCana) and its contractors (Contractor) to minimize the spread and establishment of noxious weeds and non-native invasive species. Measures identified in this plan apply to work within the project area defined as the right-of-way, access roads, temporary use areas, and other areas used during construction of the project. EnCana and Contractor personnel are to be thoroughly familiar with this plan and its contents prior to initiating construction on the project. 1.1 Purpose EnCana is committed to preventing the introduction of noxious weeds during construction and controlling the expansion of existing noxious weed populations over the life of the project. The purpose of this plan is to prescribe methods to treat existing weed infestations, prevent introduction and spread of infestations during construction, and monitor and treat infestations after construction is complete. This plan was developed as the implementing document for relevant mitigation measures contained in the Environmental Assessment. 2.0 NOXIOUS WEED MANAGEMENT 2.1 Identification and Treatment of Problem Areas Field surveys will be conducted each spring prior to construction to identify existing noxious weed infestations along the pipeline right-of-way and temporary use areas. Infestation locations will be provided in Attachment 1. Noxious weed infestations will be flagged in the field to alert construction personnel to the infestation and prevent significant ground disturbance until noxious weed preventative measures have been implemented. EnCana will consult with the BLM and local weed control districts to determine pre-treatment for noxious weed infestations identified during spring surveys. Depending upon the species and the time of construction, methods of pre-treatment may include: • Mechanical—mowing or pulling by hand. • Chemical—application of an approved herbicide by a licensed applicator. Herbicides will be selected based on recommendations by each local weed control district or BLM and subject to fee -landowner approval. All herbicides will be applied in accordance with all applicable laws and regulations on BLM and fee -lands. Prior to the use of herbicides or pesticides on BLM lands, a Pesticide Use Proposal (PUP) must be submitted to and approved by the BLM. Potential sites for equipment and vehicle wash stations will be identified in consultation with Piceance Gathering Pipeline Project March 2006 Noxious Weed Management Plan local weed control districts and the BLM to minimize the potential for the transport of seeds or viable plant materials from infested areas. Signs will be posted along the right-of-way to alert approaching construction crews to wash station locations. A portion of the environmental training, required for construction personnel prior to commencing work, will be devoted to a discussion of noxious weed control issues and applicable project requirements. 2.2 Preventative Measures The following preventative measures will be implemented to prevent the spread of noxious weeds: • Vehicles and equipment will be required to arrive at the work site clean, power -washed, and free of soil and vegetative debris capable of transporting weed seeds or other propagules. • Wash stations will be required at designated infestation areas. Equipment will be power - washed to remove soil and propagules prior to leaving the infested area. Wash stations will be constructed in accordance with the typical drawing in Attachment 2. • Materials used for erosion control and reclamation (i.e. straw bales and seed mixes) will be obtained from sources that are certified weed -free. • Disturbed areas will be reseeded in accordance with the Reclamation Plan as soon as possible after construction activities have been completed. 2.3 Monitoring EnCana will continue to monitor the distribution and density of noxious weeds on the right-of- way for the life of the pipeline. Surveys will be conducted concurrently with reclamation monitoring and will occur as early in the year as feasible to identify and control noxious weeds before they produce seed. Monitoring data collected will include the noxious weed species, location, and extent of infestation. At those locations where new populations have been identified or pre-existing populations have expanded, EnCana will take action to eradicate the population or control their spread. The selection of control methods will be based on the available technology and information of the weed species. Methods of control may include those listed in Section 2.1. Noxious weed problems identified after reclamation criteria have been met (refer to the Reclamation Plan) will be addressed in a joint endeavor between EnCana, the fee -landowner or BLM, and the local weed control district. 2 Piceance Gathering Pipeline Project March 2006 Noxious Weed Management Plan Attachment 1 ATTACHMENT 1 -NOXIOUS WEED INFESTATIONS Piceance Gathering Pipeline Project March 2006 Noxious Weed Management Plan—Anachment 1 (Will be provided prior to construction.)

(EnCana) and its contractors (Contractor) to avoid or minimize adverse impacts to paleontological resources during construction and subsequent reclamation, restoration, and maintenance activities. Measures identified in this plan apply to work within the project area defined as the right-of-way (ROW), access roads, temporary use areas, and other areas used during construction of the project. EnCana and Contractor personnel are to be thoroughly familiar with this plan and its contents prior to initiating construction on the project. 1.1 Purpose The purpose of this plan is to provide for the identification, evaluation, and treatment of paleontological resources that may be impacted as a result of construction of the project. This plan also defines the responsibilities and measures to preserve and protect paleontological resources during construction of the project. This plan was developed as the implementing document for relevant mitigation measures contained in the Environmental Assessment. 2.0 RESPONSIBILITIES 2.1 EnCana EnCana will employ standard operating procedures during construction to protect paleontological resources. EnCana will: • Implement paleontological monitoring by a BLM-approved paleontologist during construction for project areas determined to be sensitive for paleontological resources. • Include specific language in the Contractor's specifications regarding trespass on sites and procedures to be followed during unexpected discovery. • Use procedures described in Sections 5.0 to deal with the inadvertent exposure of vertebrate fossils during construction. 2.2 Contractor The Contractor will be responsible for following the project procedures and requirements defined in this plan during and after the exposure of paleontological resources. The Contractor will be responsible for providing EnCana's Environmental Inspector with adequate advance notification (72 -hour minimum notice) of construction activities so that paleontological monitors can be deployed where required. Piceance Gathering Pipeline Project March 2006 Paleontological Resources Protection Plan 2.3 Environmental Inspector EnCana's Environmental Inspector will monitor daily construction activities, and is responsible for ensuring pipeline construction activities comply with all applicable mitigation requirements, permit conditions, and environmental specifications relating to paleontological resources protection. This includes keeping track of construction activities and ensuring that monitors will be on-site when construction activities require paleontological monitoring. 3.0 TRAINING The Contractor will inform all crews of requirements relating to paleontological resource protection. All construction personnel who operate ground -disturbing equipment will receive special instruction on the types of fossils that may be encountered and the procedures to be followed if they encounter fossils. All construction and other employees present on the right-of- way will be informed of both the Environmental Inspector and Paleontological Monitor's authority to halt work. All personnel will be informed that they are subject to prosecution for knowingly disturbing fossil localities, or for collecting fossils. Violation may result in removal from the project and/or may result in civil or criminal penalties. 4.0 MONITORING AND REPORTING REQUIREMENTS Paleontological resource monitoring will be conducted by Paleontological Monitors to ensure that fossils are preserved and to ascertain whether construction may continue after the unexpected discovery of any vertebrate fossils. 4.1 Monitoring Paleontological Monitors will monitor project construction through Condition I formations and will spot-check construction activities through Condition II formations. The Contractor is responsible for notifying EnCana's Environmental Inspector at least 72 hours in advance of areas requiring monitoring, so that paleontological monitors can be deployed where required. The Contractor will be responsible for all construction delays due to insufficient notification. Areas requiring paleontological monitoring are included in Attachment 1. Paleontological monitoring in Condition I formations will consist of monitoring trenching activities. The Paleontological Monitor will follow the ditching equipment at a cautionary distance, allowing time for construction dust to settle and for visible detection of fossils. At the Meeker Gas Plant, a monitor will be present at any time it becomes necessary to excavate into the underlying bedrock formation. Paleontological monitoring in Condition II areas will involve periodically spot-checking the trench prior to backfill activities. 4.2 Reporting Paleontological Monitors will document daily monitoring activities on daily monitoring report 2 Piceance Gathering Pipeline Project March 2006 Paleontological Resources Protection Plan forms that will be delivered to the Environmental Inspector on a daily basis. Paleontological monitoring results will be reported on a bi-weekly basis to the BLM Authorized Officer in a short letter report. 5.0 DISCOVERY REQUIREMENTS If vertebrate fossils are discovered during construction, the Contractor will immediately stop all work near the discovery. The following steps will be implemented when vertebrate fossils are discovered: • Cease all earth disturbing activity within 100 feet of the discovery. • Contact the BLM Authorized Officer, Environmental Inspector, and Paleontological Monitor immediately. At the direction of the BLM, the Paleontological Monitor will assess the nature of the discovery and determine the necessary course of action. If necessary, the Paleontological Monitor will mark the area and recommend procedures to be implemented to avoid further site damage. EnCana will protect the discovery until removed.

(EnCana) and its contractors (Contractor) for topsoil restoration, reseeding, and reclamation monitoring. Measures identified in this plan apply to work within the project area defined as the right-of-way, temporary use areas, and other areas used during construction of the project. EnCana and Contractor personnel are to be thoroughly familiar with this plan and its contents prior to initiating construction on the project. 1.1 Purpose The purpose of this plan is to describe prescribed methods for topsoil replacement, reseeding, and monitoring for reclamation success. This plan was developed as the implementing document for relevant mitigation measures contained in the Environmental Assessment. 1.2 Goals and Objectives The short-term objectives of reclamation are to control erosion and sedimentation and to minimize impacts to adjacent land uses. Properly executed construction practices and optimum scheduling will mitigate short-term impacts. Long-term objectives include controlling erosion and sedimentation, protecting water resources and soils, limiting the introduction and spread of noxious weeds, and returning disturbed areas to pre-existing condition. Monitoring during construction and post -construction will ensure that these goals are achieved. 2.0 RESPONSIBILITIES 2.1 EnCana EnCana will be responsible for ensuring that the Contractor meets the standards defined in this plan to restore all disturbed areas to pre -construction conditions and to ensure long-term monitoring of restoration success. EnCana will take remedial actions as necessary to restore and maintain a stable vegetative cover on the right-of-way. EnCana will provide the Contractor with the appropriate blended seed mixes developed through consultation with the BLM and fee - landowners. EnCana will be responsible for reclaiming the entire right-of-way after each phase of construction. 2.2 Contractor The Contractor will be responsible for seeding the right-of-way, temporary use areas, and off - right -of -way ancillary sites following their construction activities. Reclamation will be conducted according to this plan as specified for the Contractor. Piceance Gathering Pipeline Project March 2006 Reclmnation Plan 2.3 Environmental Inspector EnCana's Environmental Inspector will have the responsibility to ensure field activities are performed in accordance with this plan by the Contractor and in compliance with all other permits and agreements. The Environmental Inspector will have the authority to make site- specific field changes in certain reclamation procedures within the guidelines of this plan in consultation with the fee -landowner or BLM. 3.0 RECLAMATION PROCESS The following sections outline the pre -construction planning and sequential steps for restoring the right-of-way and temporary use areas following installation of the pipe and backfilling of the trench. 3.1 Agricultural Features All irrigation ditches, cattle guards, fences, and artificial and natural livestock and wildlife water sources will be maintained and repaired to at least pre -construction conditions. Temporary measures will be provided, as agreed with the fee -landowner or BLM, for any of these facilities that are disrupted during the construction or reclamation process. BLM fence specifications are included in Attachment 3 of the Plan of Development. 3.2 Rock Disposal Excess rock is defined as all rock that cannot be returned to the existing rock profile in the trench or graded cuts, or is not needed to restore the right-of-way surface to a condition comparable to that found adjacent to the right-of-way. Excess rock will be randomly distributed across the right-of-way, piled or windrowed to create or enhance wildlife habitat, or arranged to block use of the right-of-way by motor vehicles. If not practical, the Contractor will remove other excess rock from the right-of-way and haul it to an approved disposal site. EnCana will coordinate with fee -landowners or the BLM regarding the methods of disposal. On irrigated agricultural lands, rocks will be removed from at least the top 12 inches of soil and diligent efforts will be made to remove stones greater than 4 inches in any dimension if the off - right -of -way areas do not contain stones greater than 4 inches in any dimension. Requirements for rock removal may vary between fee -landowners and will be listed in the Fee -Lands Line List, included in Attachment 2 of the Plan of Development. 3.3 Final Cleanup Within 30 days after backfilling the trench, the Contractor will make every effort to complete final cleanup and installation of permanent erosion control structures. The right-of-way and other project -related areas where soil has been disturbed will be restored as close to pre -construction grades, compaction, and other conditions as possible. No solid waste, rock, trash, or vegetative debris will be buried on the right-of-way. 2 Piceance Gathering Pipeline Project March 2006 Reclamation Plan Irrigated agricultural lands are of special concern and require precise re -contouring and trench compaction to return fields to pre -construction conditions. The Contractor will work closely with fee -landowners to ensure irrigated agricultural lands are effectively restored. Final compaction of disturbed areas will be returned to approximate pre -construction conditions. Any compacted areas, including but not limited to the travel lane, will be decompacted. Compacted areas will be decompacted with a scarifier to a depth of 6 to 10 inches prior to topsoil replacement and seeding. Compacted areas on irrigated agricultural land where topsoil was not salvaged will be decompacted to a depth of 18 inches using a paraplow or other deep tillage implement so as not to mix topsoil and subsoil horizons. 3.4 Topsoil Restoration After the trench has been backfilled and the right-of-way regraded, the Contractor will redistribute topsoil to the approximate location from which it was originally removed. Restored topsoil will be left in a roughened condition to discourage erosion and enhance the quality of the seedbed. Topsoil will not be handled during excessively wet or frozen conditions. Topsoil will be redistributed as close to original salvage depths as possible. Salvage methods are discussed in the Soil Conservation, Sedimentation, and Erosion Control Plan. Segregation of subsoil and topsoil will be maintained throughout final cleanup procedures. The Contractor will be responsible for replacement of lost or degraded (mixed) topsoil with topsoil imported from an EnCana-approved and certified weed -free source. Additional erosion control and soil stabilization will be required in areas adjacent to or within drainages. See the Soil Conservation, Sedimentation, and Erosion Control Plan and the Waterbody Crossing and Wetland Protection Plan for additional information. 3.5 Permanent Erosion Control Permanent erosion control methods will be utilized as needed for stabilization of slopes and soils as described in the Soil Conservation, Sedimentation, and Erosion Control Plan. Permanent erosion control measures will be installed within 30 days after the trench is backfilled to aid in site stabilization wherever required. 3.6 Rock and Vegetative Debris Vegetative mulch and excess rock may be used to reduce erosion potential by providing additional surface relief structure. In areas with a pre-existing rocky surface material, the Contractor will spread rock over the right-of-way to maintain a surface appearance similar to that of adjacent undisturbed terrain. Suitable sites include naturally rocky slopes and areas that have a natural gravel, cobble, or boulder veneer on the surface. Suitable sites will be determined in conjunction with the BLM or the fee -landowner. On BLM lands and where approved by the fee -landowner, the Contractor will randomly distribute any windrowed trees, shrubs or other remaining vegetation debris over the right-of- Piceance Gathering Pipeline Project 3 March 2006 Reclamation Plan way. On lands administered by the WRFO BLM, dispersed vegetative debris will not exceed 3 to 5 tons/acre. Vegetative dispersal must be accomplished by hand or with appropriate equipment after seeding of the right-of-way so the spread material will not interfere with the performance of seeding equipment and to prevent disturbance of the seedbed. Straw mulch or equivalent will be applied as discussed in the Soil Conservation, Sedimentation, and Erosion Control Plan. 3.7 Seedbed Preparation The Contractor will scarify, till, or harrow the seedbed to a depth of 3 to 4 inches prior to seeding where needed to improve revegetation potential. Those sites where seedbed preparation is not practical (e.g., steep slopes, rocky areas, etc.) will be left with adequate roughness following topsoil replacement to create micro -environments for seed germination and growth, and to reduce the potential for soil movement. 3.8 Soil Supplements Generally, fertilizer will not be used unless requested by the fee -landowner. At this time, no areas have been identified that require fertilizer. 3.9 Revegetation The Contractor will be responsible for seeding the right-of-way, temporary use areas and off - right -of -way ancillary sites using EnCana-supplied seed mixes, appropriate seeding methods, and approved application rates. The seeding requirements and scheduling of reclamation activities will be determined in coordination with BLM or fee -landowner. 3.9.1 Species Selection and Sources Selection of grass and shrub species for revegetation will be based on pre -construction community composition and soil types, as well as establishment potential, soil stabilizing qualities, post -construction land use objectives, and BLM and fee -landowner recommendations. Native species will be utilized on BLM lands and native species will be utilized to the extent possible on fee -lands unless non -natives are specifically requested by a fee -landowner. Project seed will be certified weed -free and will be purchased from and blended by qualified producers and dealers. Seed mixes will be purchased from commercial seed vendors and must be state -certified weed - free mixtures. Seed bag tags will be collected and submitted to the BLM and appropriate county to confirm that the seed was purchased from a commercial seed vendor and was tested and certified. Seeding rate will be listed as pounds per acre of pure live seed (PLS). The Contractor will be responsible for providing all seed tags to the Environmental Inspector at the end of each day. The Environmental Inspector will provide seed tags and stationing seeded to the Environmental Manager who will provide the seed tags and stationing seeded to the BLM or county. Approved seed mixes, rates, and application areas are identified in Attachment 1. 4 Piceance Gathering Pipeline Project March 2006 Reclamation Plan 3.9.2 Seed Application Rates and Viability Seeding rates will be determined in PLS pounds per acre and seeds per square foot based on drilled application rates. Broadcast seeding rates will be twice the drill rate. Seed will be used within 12 months of testing to assure seed viability. If additional seeding is required in the year following construction, additional viability tests will be conducted to determine any need for adjustment of application rates. Wetlands will not be seeded. Successful recolonization by wetland species is generally related to effective topsoil salvage methods and sources of seed and rhizomes in adjacent areas. Streambanks will be seeded immediately upon completion of final cleanup as described in the Waterbody Crossing and Wetland Protection Plan. 3.9.3 Seeding Methods and Procedures The Contractor will employ broadcast or drill seeding as determined in the field by EnCana. Seeding activities will be contingent upon weather and soil conditions, and subject to evaluation by the Environmental Inspector. Seeding will not be permitted if there is more than 2 inches of snow on the ground unless approved by the Environmental Inspector and BLM Authorized Officer or field representative. On BLM lands and where approved by the fee -landowner, the Contractor will randomly distribute any windrowed trees and shrubs or other remaining vegetation debris over the right-of-way (after seeding) by hand or with appropriate equipment so as not to disturb the seedbed. 3.9.3.1 Drill Seeding Drill seeding is the preferred seeding method and will be employed wherever soil characteristics and slope allow effective operation of a rangeland seed drill. Drill seeding will be performed perpendicular to the slope. Seed will be placed in direct contact with the soil at an average depth of 0.5 -inches, covered with soil, and firmed to eliminate air pockets around the seeds. Seed will be applied using a rangeland seed drill with a seed release and agitation mechanism sufficient to allow seeds of various sizes and densities to be planted at the proper seeding depth. 3.9.3.2 Broadcast Seeding Broadcast seeding will be employed only in areas where drill seeding is unsafe or physically impossible. Seed will be applied using manually operated cyclone -bucket spreaders, mechanical spreaders, or blowers. Seed will be uniformly broadcast over disturbed areas. Broadcast application rates will be twice that of drill rates. Immediately after broadcasting, the seed will be uniformly raked, chained, dragged, or cultipacked to incorporate seed to a sufficient seeding depth. If the area is seeded prior to a soil crust forming, harrowing or raking may not be necessary. 3.10 Grazing Prior to and during construction, EnCana will keep grazing allotment permittees on BLM lands and ranchers on fee -lands informed regarding schedules to allow them ample opportunity to Piceance Gathering Pipeline Project 5 March 2006 Reclamation Plan move livestock away from the right-of-way. Gates and fences will be installed along the right-of- way as required. Hard or soft plugs will be left or installed to allow livestock to cross to either side of the right-of-way during construction. Gates, fences, and cattle guards will be repaired or replaced after construction as agreed to with the fee -landowner or BLM. These facilities will be left in as good as or better shape than the pre -construction condition. Fences crossed by the pipeline and cattle guards or gates on access roads or within the right-of- way damaged during construction on BLM lands will be rebuilt or replaced in accordance with BLM specifications. BLM specifications are included in Attachment 3 of the Plan of Development. Fences will be properly braced prior to cutting and the permittee or rancher will be provided the opportunity to be present when the fence is cut and repaired. Riparian areas on BLM lands will be fenced until reclamation is successful. Fence will be installed around the incised banks and channel with a sufficient gap to allow for passage of wildlife or livestock up or down the channel. 4.0 RECLAMATION SCHEDULE AND DOCUMENTATION Reclamation activities will be determined in part by construction schedules and seasonal climatic conditions. Seeding and planting will be coordinated with other reclamation activities to occur as soon after seedbed preparation as possible. The Contractor will complete permanent reclamation activities prior to the end of the typical fall planting season. Fall seeding would be completed after September Pt and prior to prolonged ground frost. If necessary, spring seeding will be completed when the ground thaws and prior to May 15`h. Upon completion of reclamation, EnCana's Construction Inspector, Environmental Inspector, and Land Agent will perform a final inspection of the right-of-way and ancillary facilities to verify that pre -construction commitments have been satisfied. A copy of the post -reclamation inspection form will be transmitted to the Contractor if any deficiencies or a need for remedial action is noted. 5.0 POST -CONSTRUCTION MONITORING AND EVALUATION 5.1 Revegetation and Erosion Control Monitoring During the first growing season following construction and reclamation, EnCana will conduct intensive surveys to assess revegetation success, evaluate erosion control measures, and determine the need for further reclamation. Revegetation monitoring will include evaluation of the following parameters as compared to adjacent (off -right-of-way) vegetation: • percent total herbaceous cover (seeded species plus desirable volunteers), • new or expanded populations of noxious weeds, and • species composition. 6 Piceance Gathering Pipeline Project March 2006 Reclamation Plan Areas with poor germination and/or growth will be evaluated to determine, if possible, the cause of the problem. Reclamation techniques will be modified as necessary to address any identified problems and appropriate remedial measures will be undertaken. The Contractor will be responsible for remediating any problem areas identified by EnCana for the first growing season following construction. Thereafter, EnCana will be responsible for obtaining a reclamation contractor to perform any necessary work. Erosion control monitoring will be performed in response to significant weather events and/or concurrently with the revegetation monitoring during the first year following construction. Success criteria for both are discussed in Section 5.1.2. Both erosion control and revegetation monitoring will be conducted routinely throughout the life of the pipeline to evaluate long-term survival of reestablished vegetation and the effectiveness of erosion control measures with specific attention to problem sites. 5.1.1 Monitoring Agricultural Fields EnCana will periodically monitor irrigation ditches and irrigated agricultural fields for two years following construction to ensure that field flow characteristics have been maintained. The Contractor will be notified if any remedial work is required. 5.1.2 Evaluating Reclamation Success EnCana is responsible for the stability and revegetation of all areas disturbed as a result of construction for the life of the pipeline. As discussed in Section 5.1, EnCana will conduct intensive monitoring after the first growing season and routinely thereafter to assess soil stability and revegetation success. The Contractor will reseed any portion of the right-of-way that does not exhibit 50 percent total herbaceous cover (comprised of seeded species plus desirable volunteers) relative to adjacent (off -right-of-way) vegetation after the first complete growing season. Additional seeding will be completed during the next seeding season (fall or spring). In the event that first year revegetation is affected by precipitation amounts significantly below the annual average, EnCana may request deferment of additional seeding activities until the following seeding window. The reclaimed right-of-way will be considered stable when the surface appears similar to adjacent undisturbed land and the following accelerated erosion indicators do not exist: • perceptible soil movement (exceeding pre -construction conditions), • flow pattern development resulting in rills or gullies greater than 12 inches in depth , or • trench subsidence or slumping. Revegetation will be considered successful when the following criteria are met: • total herbaceous (seeded species plus desirable volunteers) cover is at least 70 percent of that on adjacent land, and Piceance Gathering Pipeline Project 7 March 2006 Reclamation Plan • species composition is comprised of a mix of seeded species and desirable volunteers from adjacent communities. 5.2 Post -Construction Reporting EnCana will include a discussion of soil stability, vegetation success, noxious weed status and control treatments, and identified problems as part of a post -construction activity report to be submitted annually to the BLM until success criteria for all sites are met. 8 Piceance Gathering Pipeline Project March 2006 Reclamation Plan—Attachment 1 ATTACHMENT 1—APPROVED SEED MIXES, RATES, and APPLICATION AREAS Piceance Gathering Pipeline Project March 2006 Reclamation Plan -Attachment 1 Seed Mixes Species Rates1 (lbs PLS/a) Application Areas (mileposts) Standard GJFO Seed Mix Western Wheatgrass (Arriba) 3.0 0.0 to 8.0 Pubescent Wheatgrass (Luna) 3.0 Indian Ricegrass (Paloma) 2.5 Four -wing Saltbush (Rincon) 1.0 Shadscale 1.0 10.5 High Elevation Sage Grouse Seed Mix Bluebunch wheatgrass (Secar) 1.0 8.0 to 22.0 Slender wheatgrass (Pryor) 1.0 Big bluegrass (Sherman) 1.0 Canby bluegrass (Canbar) 1.0 Mountain brome (Bromar) 1.0 Blue flax (Appar) 0.5 Rocky mountain penstemon 0.5 Arrowleaf balsamroot 1.0 Utah sweetvetch 1.0 8.0 Mid -Elevation Sage Grouse Seed Mix Western wheatgrass (Rosanna,) 1.0 22.0 to 30.0 Indian ricegrass ( Rimrock) 1.0 Bluebunch wheatgrass (Whitmar) 1.0 Thickspike wheatgrass (Critana) 1.0 Letterman needlegrass 1.0 Globemallow 0.5 Utah sweetvetch 1.0 Arrowleaf balsamroot 1.0 7.5 Standard WRFO Seed Mix (Native Seed Mix #2) Western wheatgrass (Rosanna) 2.0 30.0 to 38.0 Indian ricegrass (Rimrock) 1.0 43.0 to 44.5 Bluebunch wheatgrass (Whitmar) 2.0 Thickspike wheatgrass (Critana) 2.0 Globemallow 0.5 Fourwing saltbush (Wytana) 1.0 8.5 Piceance Gathering Pipeline Project March 2006 Al -1
