(2) Project Overview: a description of the project including the length of the pipeline, diameter of the pipeline, pipeline commodity, and the general description of the pipeline route. EnCana Oil & Gas (USA) Inc. (EnCana) is proposing to construct, operate, and maintain an up to 24 -inch diameter, steel natural gas pipeline in Garfield and Mesa Counties. The project is being referred to as the Collbran Pipeline Project and is approximately 21.81 miles in length. The proposed pipeline is located in Section 31, Township 9 South, Range 95 West, Sections 7, 19, 27, 28, 29, 30, 34, 35, & 36, Township 9 South, Range 96 West, Sections 12, 13, & 24, Township 9 South, Range 97 West, Sections 8, 16, 17, 20, 29, 31, & 32, Township 8 South, Range 96 West in Mesa County, Colorado, and in Sections 4, 8, & 9, Township 8 South, Range 96 West, and Sections 27, 33, & 34, Township 7 South, Range 96 West in Garfield County, Colorado. The proposed pipeline will transport future volumes of unprocessed natural gas from the Collbran and Plateau Valleys to the existing EnCana operated Orchard Compressor Station located in the Southwest'' 'A of Section 27, Township 7 South, Range 96 West. The proposed Collbran Pipeline will be constructed within Mesa County, Colorado for approximately 18.2 miles and will be constructed in Garfield County for approximately 3.61 miles. The remainder of the narrative will only describe portions of the project located within Garfield County, Colorado for the purpose of the Garfield County Pipeline Development Plan requirements. Please note that the entire project in Grafeld County will be described; however; EnCana is requesting permission for the northern -most 2.6 miles (MP 19.2 to 21.8) of the project (Collbran Phase 1). After the BLM ROW -Grant has been approved, EnCana will submit an administrative request for the remainder of the project. Total disturbance for Phase 1 is 52.6 acres (23.6 acres for the pipeline and an additional 29 acres will be disturbed for staging areas/pipe/contractor yards). The legal description for Phase 1 is T8S, R96W Section 4; T7S, R96117 Sections 27, 33, and 39; and T8S, R95W Sections 5 and 6. Development Flan Application May 2008 Collbran Pipeline Project (3) Ownership A. For individual right-of-way, a diagram showing adjacent properties and the approximate location of buildings and their uses within a distance of 350 feet of any proposed structure, facility, or area to be disturbed. This may be drawn at a smaller scale than the site plan. B. For an area plan, the map will show the property boundaries and ownership information for all private and public property include in the development area. The application binder contains several diagrams that depict adjacent properties. Garfield County Assessor Maps are provided in the Landowner Tab, topo maps depicting ownership are provided in Attachment 1 of the Narrative Tab, and aerial alignment sheets depicting ownership are provided in Attachment 2 of the Narrative Tab. There is only one building located within 350 feet of the pipeline corridor and staging areas. The building is a barn located on the Colohan Family Trust property. The project will have no impacts on the barn. (4) Evidence of surface owner notification and of surface agreements where the surface owner is not a party to the mineral lease. The affected landowners are the BLM, Keinath, Colohan Family Trust, and Tipping et al. Contact information for the fee -landowners are provided in the Landowners Tab. Specialty Restaurants is also an affected landowner because both staging areas/pipe/contractor yards are located on property owned by Specialty. EnCana did not determine if the surface owners are party to the mineral lease and is instead providing copies of all surface use agreements with affected landowners. Copies of the agreements are provided in the Landowners Tab. (5) Need for Proposed Action: a statement of the reason for the pipeline. EnCana plans to increase production in the Collbran/Plateau Valley area by approximately 50 to 100 million standard cubic feet per day (mscfd), each year, for the next several years. The Collbran Pipeline Project will provide a natural gas gathering system that will transport the projected future volumes of natural gas from the western slope of Colorado and the Rocky Mountain region to major interconnections with interstate pipelines. The proposed pipeline will transport approximately 650 mscfd of natural gas from the Collbran/Plateau Valley area of western Colorado to the Meeker Gas Plant in Rio Blanco County for processing. The pipeline has been sized to accommodate EnCana's current and future estimated gas production and has been designed to accommodate existing and future natural gas from other natural gas producers in the Collbran/Plateau Valley area. This pipeline will transport untreated gas to a central processing facility (Meeker Gas Plant) and will provide other producers an opportunity to transport their gas to the Meeker Gas Plant. This will allow other producers to transport their gas out of the Collbran/Plateau Valley without installing gas treatment and processing facilities. Natural gas liquids would be transported via existing pipeline from the Meeker Gas Plant to the MAPCO pipeline in Utah and the processed natural gas would be 3 Development Plan Application l'IM 2008 Cofinnan Pipeline Project delivered to the Entrega/Rockies Express Pipeline or other interstate pipeline sales outlets. The proposed pipeline would be one of the outstanding pieces in EnCana's Piceance Basin strategy. In 2005, EnCana received a permit from the BLM (COC -67980) to constntct and operate a 1.6 billion standard cubic feet of gas per day natural gas processing facility and 205 miles of natural gas, natural gas liquids, and water pipelines to and from the processing facility. EnCana's Piceance Basin Strategy, maximizes processing technology and minimizes the number of processing facilities, land disturbance, noise, and truck traffic, by constructing and utilizing existing off -specification gas pipelines throughout the Piceance Basin to deliver unprocessed gas to a central processing facility, the Meeker Gas Plant owned by Enterprise. The Meeker Gas Plant will have pipelines that deliver natural gas liquids to an existing natural gas liquids pipeline in Utah and that deliver residue gas to intrastate pipeline sales outlets. EnCana's existing and planned pipeline infrastructure allows EnCana and other natural gas producers the opportunity to transport unprocessed natural gas from natural gas fields in Rio Blanco, Garfield, and Mesa Counties without having to construct additional treatment and processing facilities.

Derclopment Plan Application U,w 2008 CoIlbron Pipeline Project EnCana proposes to use contractor and pipe storage yards on a temporary basis to support construction activities. Both yards are located on property owned by Specialty Restaurants. Maps are included in Attachment 3 in the Narrative Tab. Associated aboveground appurtenances proposed by EnCana include meter stations/valve sets, cathodic protection equipment, and pipeline markers. A meter station/valve set/launcher-receiver will be required at the interconnect to the Orchard Compressor Station. In addition to meters, the meter station 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. 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. (9) Construction Schedule: indicate the estimated start and end dates for construction, days of the week in which construction will occur, hours of day during which construction will occur. Construction activities will take approximately 6 months, are tentatively scheduled for July 2008, and will continue through the fall/winter of 2008. Working hours will normally range from 7:00 AM to 5:00 PM Monday through Saturday. (10) Sensitive Area Survey: List the types and areas of concern along the pipeline right-of-way, such as: sensitive plant populations, cultural, archeological, paleontological resources and wetlands identified during pre -construction environmental surveys, if applicable. EnCana has completed cultural, paleontological, biological and noxious weed surveys in accordance with BLM protocols. Copies of resource surveys are included in the Resource Surveys Tab. Please note that biological surveys were completed in the fall of 2007 and will be completed in spring 2008 prior to construction. If survey results differ from 2007, EnCana will submit the new information to the County. The project will not affect any federally listed threatened or endangered species. EnCana will adhere to the BLM recommendations to avoid construction activities between December 1 and April 30 in big game wintering habitat. If nesting raptors are found during construction, EnCana will adhere to buffer zones and timing limitations as recommended by the BLM. Depending on the species, buffer zones are typically 0.25 to 0.5 miles wide and timing limitations would be typically between March 1 and August 15. Several cultural sites were identified within or near the proposed pipeline corridor. The BLM has not identified the locations of cultural resource sites along the project route and it is unknown Development Plan Application 3 May 2008 Collbrarr Pipeline Project whether any of these sites occur within Garfield County. EnCana will adhere to BLM recommended mitigation for these areas. EnCana will comply with the general terms and conditions of the Army Corps of Engineers Nationwide General Permit number 12, included in the NWP 12 Preconstmction Notification section of the Permits Tab. (11) Land Grant/Permits/Authorizations and Stipulations: attach a copy of any land grants, permits, and authorizations including stipulations. Copies of the NWP 12 PCN, CDPHE Construction Emissions, and the CDPHE Stoimwater permits are included in the Permits Tab. Copies of the BLM ROW Grant, CDPHE M[NDI and Garfield County Utility permits will be provided to the County upon receipt. (12) Revegetation Plan: a. A plant material list. Be specific, scientific and common names are required. Include application rate in terms of pure live seed (PLS) per acre/. b. A planting schedule that includes timing, methods, and mulching. c. A revegetation security. A security may be required if, in the determination of the County Vegetation Management, the proposed project has: (i) A potential to facilitate the spread of noxious weeds. (ii) A potential to impact watershed areas. (iii) A potential for visual impacts from public viewing corridors. (iv) Steep slopes (15% or greater) or unstable areas. (v) Disturbs large areas (Half an acre or greater) d. The revegetation security will be in an amount to be determined by the County Vegetation Management that will be site-specific and based on the amount of disturbance. The security shall be held by Garfield County until vegetation has been successfully reestablished, or for a period of time approved by the County Vegetation Management in any specific land use action, according to the Reclamation & Revegetation Standards Section in the Garfield County Weed Management Plan. The County Vegetation Management will evaluate the reclamation and revegetation prior to the release of the security. Seeding and reclamation activities will begin after final clean-up activities have been completed in the fall of 2008. Disturbed areas will be reseeded with the approved fee -landowner and BLM seed mixtures. EnCana will only use seed that is certified weed -free. Seed bag tags will be collected and submitted to the BLM within 30 days of seeding for the sections of the project on BLM lands and the sections of the project on private land will be submitted to the Garfield County Vegetation Manager at the completion of the project. Seeding rate will be listed as pounds per acre of pure live seed (PLS). The following seed mix was recommended by WestWater Engineering in the Integrated Vegetation and Noxious Weed Management Plan (included in the Resource Surveys Tab) and is subject to change based on recommendations from the BLM or final landowner requirements. 6 Development Plan Application 61.AY 2008 Collbran Pipeline Project Recommended Seed Mix Species (Common) Species (Scientific) Varietv Seed in• Rate (PLS*/a) Plant the following: Indian ricegrass Achnatheram (Oiyzopsis) hymenoides Nezpar, Paloma, Rinuock 1.3 Galleta Pleuraphis (Hilaria) jmnesii Viva florets 1.7 Bluebunch wheatgrass Agropyron spicatum Secar, P-7, Anatone 1.9 and one of the following: Thickspike wheatgrass Agroptyon dasystachyum Critana, Schwendimar 2.3 Slender wheatgrass Agropyron trachycaulurn San Luis 2.3 Western wheatgras Arriba 2.0 and two of the following: Muttongrass Poa fendleriona 0.4 Sandberg bluegrass Pon sandbergii 0.4 Bottlebrush squirreltail Elymus elymoides - 1.8 *Pure Live Seed Total up to 14.1 EnCana will provide a revegetation security to Garfield County for the amount of $154,250 or $2,500 per acre of disturbance (61.7 acres) for the Collbran Pipeline Project. (13) A weed management plan for all Garfield County listed noxious weeds and State of Colorado listed noxious weeds that are targeted by the Commissioner of Agriculture for statewide eradication. Noxious weed surveys were completed by WestWater Engineering Inc. for the proposed Collbran Pipeline Project and by Wildlife Specialties for the proposed contractor/pipe/staging areas. The Integrated Vegetation and Noxious Weed Management Plan and Habitat Assessment are included in the Resource Surveys Tab. (14) Emergency Response Plan: include a fire protection and hazardous material spills plan, which specifies planned actions for possible emergency events, a listing of persons to be notified of all emergency events, a listing of person to be notified of an emergency event, proposed signage, and provisions for access by emergency response teams. The emergency plan must be acceptable to the appropriate fire district or the County Sheriff, as appropriate. The plan shall include a provision for the operator to reimburse the appropriate emergency service provider for costs incurred in connection with emergency response for the operator's activities at the site. EnCana 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 provided in the Emergency Response Tab. Detailed safety measures and notification protocols are presented in EnCana's Fire Prevention and Suppression Plan, Strength Testing Plan, and Safety Plan. These plans are included in the Plan of Development Tab. Development plan Application May 2008 Collin -nit Pipeline Project After EnCana selects a construction contractor (early June), a detailed plan will be sent to the County and the construction contractor representatives will meet with representatives from the Sheriff's department and Grand Valley Fire District. EnCana will reimburse the appropriate emergency service provider for costs incurred in connection with emergency response for activities associated with this project. (15) Traffic Impact: for construction traffic on county roads, indicate the anticipated types of vehicles, number of each type, anticipated number of trips per day per each type, county roads to be used, percentage of the construction traffic that will travel on each listed county. EnCana will utilize Garfield County Road 300 and several private roadways within Garfield County to gain access to the right-of-way during construction. Garfield County Road 300 is heavily used by the oil and gas industry, and minimal additional impact will result from the increase traffic volumes. Vehicle traffic on Garfield County Road 300 will be necessary for approximately 2 to 3 months of the project, since the majority of the project is located in Mesa County and construction crews will utilize other roadways in Mesa County to gain access to the right-of-way. The table below provides an estimate of the traffic impacts on Garfield County Road 300. 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 300 and US Highway 6. The 75 commuter trips will be from I-70 to the temporary construction yard located at the southwest intersection of County Road 300 and Highway 6. The following table depicts average (over the course of the project) estimated traffic numbers from the construction yard and pipe yard south along County Road 300 to the pipeline workspace: Traffic Impacts Vehicle Type and Number Roundtrips (yard to pipeline) Totals Buses -4 1 4 Pick-up Trucks 1 40 --40 Lowboys 2 5 10 Grease truck 1 3 3 Fuel Truck -1 3 3 Winch Truck -1 10 10 Stringing Trucks 10 50 -5 Total 120 J Development Plan Application Almy 2008 Co/lbran Pipeline Project 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. (16) Staging Areas: indicate the general location of the staging areas required for pipeline construction. EnCana will use an office and equipment staging areas/yard and a pipe storage staging areas/yard on a temporary basis to support construction activities. The proposed office and equipment yard is approximately 7 acres and the proposed pipe storage yard is approximately 22 acres. Both yards are located on Specialty Restaurants. Electricity and telephone lines will be installed at the temporary construction offices. Portable toilets will be available on-site and potable water will be transported from off-site and made available to constriction personnel. Access to the office and equipment staging area is off of Garfield County Road 300. EnCana will apply for a driveway permit prior to construction. Access to the pipe storage staging area is off of U.S. Highway 6 and will be from an existing driveway that EnCana utilizes to access the C7OU well pad. (17) Hydrotest Water: indicate the quantity of water required, source of water and the disposition of the water after testing. The Collbran Pipeline will be hydrostatic tested with water prior to being placed into service. EnCana has existing agreements for appropriating water from the Colorado River. 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 in accordance with the CDPHE MINDI permit requirements. EnCana does not anticipate discharging hydrostatic test water within Garfield County. Additional information on hydrostatic testing activities is provided in the Strength Testing Plan included in the Plan of Development Tab. 11. Referral and Review by the Planning Director: The Planning Director will coordinate the review of the development plan application. Upon the filing of a complete application for development plan review, the Planning Director shall promptly forward one copy to the County Road & Bridge, Oil & Gas Auditor, Vegetation Management and Engineering Departments; the appropriate fire district or County Sheriff; the surface owners of an individual pipeline development plan; and any adjacent municipality for comment. (1) Referral comments on the proposed development shall be returned to the Planning Director no later than 18 days from the date of application for an Development Plan Application May 2008 9 Cornwall Pipeline Project individual site application and 30 days from the date of application for an area development plan. (2) In addition, the applicant shall notify the property owners within 200 feet of the route that are not affected surface owners with an agreement with the applicant. A sign will be posted on the portions of the route crossing or adjacent to a public road within seven days after receiving the application for an individual development plan review. Both the notice and the sign shall indicate that a development plan review application has been made, and the phone number of the Planning Department where information regarding the application may be obtained. The applicant shall notify all property owners within 200 feet of the outside boundary of an area development plan and post a sign at the intersection of each public road entering the area within seven days after receiving the application for an area development plan review. Both the notice and the sign shall indicate that a development plan review application has been made, and the phone number of the Planning Department where information regarding the application may be obtained. There are two landowners that are within 200 feet of the proposed pipeline (Jolly and Strong) and one landowner that is within 200 feet of the proposed staging area/pipe/contractor yards (CDOT) that are not affected surface owners. Contact information for each adjacent landowner is included in the Landowners Tab. EnCana will provide notice to these landowners within seven days of submitting the Pipeline Development Plan to the County. Return receipt providing notification to each adjacent landowner will be provided upon receipt. EnCana will provide copies of the application binder to affected surface owners within seven days of submitting the Pipeline Development Plan to the County. (3) Any determination by the Planning Director to approve or conditionally approve a development plan application must be in writing and mailed or otherwise provided to the applicant no later than 28 days for an individual pipeline development plan or 60 days for an area pipeline development plan, after the date on which the development plan application is filed. Failure to make a determination on the application within this time period shall result in the application being considered approved and the applicant's building permit or access, or other permits being processed. 111. Development Plan Review Standards and Criteria for Approval: A development plan shall be approved or conditionally approved in accordance with the following standards and criteria. (1) Right-of-way and any associated facilities shall be located along the perimeters of surface property ownerships and not within areas of agricultural crop production as a general guide. Non -perimeter locations will be acceptable if the surface owner agrees and there is no adverse impact on adjacent properties. Development Platt Application MAY 2(108 Collbrnn Pipeline Project The pipeline route has been routed adjacent to existing pipeline and road corridors to the extent practical. All surface owners have agreed to the pipeline route. Signed surface use agreements are included in the Landowner Tab. (2) Any equipment used in construction or operation of a pipeline must comply with the Colorado Oil and Gas Conservation Commission Rules and Regulations, Section 802, Noise Abatement. a. For any pipeline construction or operational facility that will have a substantial impact in adjacent areas, additional noise mitigation may be required. One or more of the following additional noise mitigation measures may be required: (i) acoustically insulated housing or covers enclosing any motors or engines (ii) screening of the site or noise emitting equipment by fence or landscaping (iii) noise management plan specifying the hours of maximum noise and the type, frequency, and the level of noise to be emitted; and (iv) any other noise mitigation measures required by the COGCC. b. All power sources used in pipeline operations shall have electric motors or muffled internal combustion engines. 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 meters 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) Pipeline operations shall be located in a manner to minimize their visual impact and disturbance of the land surface, to the extent practical. a. The location of right-of-way shall be away from prominent natural features and identified environmental resources. b. Right-of-way shall be located to avoid crossing hills and ridges, and wherever possible, shall be located at the base of slopes. c. Facilities shall be painted in a uniform, non -contrasting, non -reflective color, to blend with the adjacent landscape. 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. Because the pipeline corridor parallels an exiting pipeline or road corridor, the visual impacts will be an incremental increase to those already existing and the new corridor will leave similar line, color, and texture contrast. Development Plan Application � May 2008 Collbrai Pipeline Projen Viewscape impacts caused by pipeline construction will be minimized by implementing measures proposed in EnCana's Reclamation Plan included in the Plan of Development Tab. EnCana will: • Restore the right-of-way to as near as possible original contours and restore natural drainage and ninoffpattems. • 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. (4) Access points to public roads shall be reviewed by the County Road & Bridge Department and shall be built and maintained in accordance with the Garfield County Road Specifications. All access and oversize or overweight vehicle permits must be obtained from the County Road & Bridge Department prior to beginning operation. All proposed transportation right-of-way to the site shall also be reviewed and approved by the County Road & Bridge Department to minimize traffic hazards and adverse impacts on public roadways. Existing roads shall be used to minimize land disturbance unless traffic safety, visual or noise concerns, or other adverse surface impacts clearly dictate otherwise. Any new roads created as a result of the pipeline construction, intended to be permanent for maintenance and repair operations shall be placed behind a locked gate or other barriers preventing use by recreational vehicles. Any gates or barriers need to be consistent with the surface owners' preferences. 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. • Use the constntction 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 Tab. • Maintain unsurfaced roads during construction of the project. 12 Development Plan Application NIM 2008 Collbinn Pipeline Project • Restore roads to equal or better condition than pre -construction levels after construction is complete. • Allow the construction contractor selected to operate under EnCana's Overweight Permit Bond No.PIB0007951 for the purpose of constructing the Collbran Pipeline Project. (5) In no case shall an operator engage in activities which threaten an endangered species. This project will not threaten any endangered species. (6) Air contaminant emissions shall be in compliance with the applicable permit and control provisions of the Colorado Air Quality Control Program, Title 25, Resolution 7, C.R.S. 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 six 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. • 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. Development Pian Application 13 May 20D8 CoI(bran Pipeline Project • 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 Tab. (7) All operations shall comply with all applicable State Public Health and Environment, Water Quality Control standards. Constriction 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 Stonnwater permit conditions. Impacts to surface water quality will be minimized by implementing measures proposed in EnCana's Stormwater Management Plan, Waterbody Crossing and Protection Plan, and Strength Testing Plan in the Plan of Development Tab. 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. • Maintain erosion and sediment control measures until streambanks and adjacent upland areas are stabilized. • Reestablish pre -constriction 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). 14 Development Plan Application N!,v 2008 Collbrnn Pipeline Project • 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. (8) Any proposed waste disposal or treatment facilities shall comply with all requirements of the County Individual Septic Disposal System 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. (9) The proposed reclamation plan shall provide for a reasonable reclamation schedule in light of the specific surface use and surrounding land uses, and may require recontouring and revegetation of the surface to pre -disturbance conditions. The Planning Director may also approve a plan for an alternative post - disturbance reclamation, provided the surface owner and the applicant agree, and the plan is in harmony with the surrounding land uses and the Comprehensive Plan. EnCana will provide a revegetation security to Garfield County for the amount of $154,250 or $2,500 per acre of disturbance (61.7 acres) for the Collbran Pipeline Project. (10) Should an abandoned pipeline be removed, it will be subject to the original revegetation and weed management requirements in the original application. 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 Development Plan Applic May 2008 15 CoUbrnn Pipeline Project 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. IV.

(EnCana) is proposing to construct, operate, and maintain an up to 24 -inch diameter, steel natural gas pipeline in Garfield and Mesa Counties. The project is being referred to as the Collbran Pipeline Project and is approximately 21.81 miles in length. The proposed pipeline is located in Section 31, Township 9 South, Range 95 West, Sections 7, 19, 27, 28, 29, 30, 34, 35, & 36, Township 9 South, Range 96 West, Sections 12, 13, & 24, Township 9 South, Range 97 West, Sections 8, 16, 17, 20, 29, 31, & 32, Township 8 South, Range 96 West in Mesa County, Colorado, and in Sections 4, 8, & 9, Township 8 South, Range 96 West, and Sections 27, 33, & 34, Township 7 South, Range 96 West in Garfield County, Colorado. The proposed pipeline will transport future volumes of unprocessed natural gas from the Collbran and Plateau Valleys to the existing EnCana operated Orchard Compressor Station located in the Southwest'' 'A of Section 27, Township 7 South, Range 96 West. The proposed Collbran Pipeline will be constructed within Mesa County, Colorado for approximately 18.2 miles and will be constructed in Garfield County for approximately 3.61 miles. The remainder of the narrative will only describe portions of the project located within Garfield County, Colorado for the purpose of the Garfield County Pipeline Development Plan requirements. Vicinity and route maps are included as Attachment 1 in the Narrative Tab and aerial alignment sheets are included as Attachment 2 in the Narrative Tab. Please note that the entire project in Garfield County will be described; however; EnCana is requesting permission for the northern -most 2.6 miles (MP 19.2 to 21.8) of the project (Collbran Phase 1). After the BLM ROW -Grant has been approved, EnCana will submit an administrative request for the southern -most mile (MP 18.2 to 19.2) (Collbran Phase II). Total disturbance Phase 1 is 23.6 acres and total disturbance for Phase II is 9.1 acres. An additional 29 acres will be disturbed for staging areas/pipe/contractor yards. Total disturbance for the project is 61.7 acres. 1.2 PURPOSE AND NEED EnCana plans to increase production in the Collbran/Plateau Valley area by approximately 50 to 100 million standard cubic feet per day (mscfd), each year, for the next several years. The Collbran Pipeline Project will provide a natural gas gathering system that will transport the projected future volumes of natural gas from the western slope of Colorado and the Rocky Mountain region to major interconnections with interstate pipelines. The proposed pipeline will transport approximately 650 mscfd of natural gas from the Collbran/Plateau Valley area of western Colorado to the Meeker Gas Plant in Rio Blanco County for processing. The pipeline has been sized to accommodate EnCana's current and future estimated gas production and has been designed to accommodate existing and future natural gas from other natural gas producers in the Collbran/Plateau Valley area. This pipeline will transport untreated gas to a central processing facility (Meeker Gas Plant) and will provide other producers an opportunity to transport their gas to the Meeker Gas Plant. This will allow other producers to Calibre!' Pipeline Project May 2008 Pipeline Development Plan transport their gas out of the Collbran/Plateau Valley without installing gas treatment and processing facilities. Natural gas liquids would be transported via existing pipeline from the Meeker Gas Plant to the MAPCO pipeline in Utah and the processed natural gas would be delivered to the Entrega/Rockies Express Pipeline or other interstate pipeline sales outlets. The proposed pipeline would be one of the outstanding pieces in EnCana's Piceance Basin strategy. In 2005, EnCana received a permit from the BLM (COC -67980) to construct and operate a 1.6 billion standard cubic feet of gas per day natural gas processing facility and 205 miles of natural gas, natural gas liquids, and water pipelines to and from the processing facility. EnCana's Piceance Basin Strategy, maximizes processing technology and minimizes the number of processing facilities, land disturbance, noise, and truck traffic, by constructing and utilizing existing off -specification gas pipelines throughout the Piceance Basin to deliver unprocessed gas to a central processing facility, the Meeker Gas Plant owned by Enterprise. The Meeker Gas Plant will have pipelines that deliver natural gas liquids to an existing natural gas liquids pipeline in Utah and that deliver residue gas to intrastate pipeline sales outlets. EnCana's existing and planned pipeline infrastructure allows EnCana and other natural gas producers the opportunity to transport unprocessed natural gas from natural gas fields in Rio Blanco, Garfield, and Mesa Counties without having to construct additional treatment and processing facilities. 1.3 LAND REQUIREMENTS 1.3.1 Right -of -Way The construction right-of-way will normally consist of 75 feet of work area for the construction of the pipeline and after the completion of the project the right-of-way will revert back to a 50 foot permanent easement for operation of the pipeline. The proposed pipeline will cross approximately 3.4 miles of fee surface and 0.2 miles of BLM administrated land. 1.3.2 Corridor The route in Garfield County parallels existing road right-of-ways and existing utility corridors. 1.3.3 Disturbance The proposed pipeline will disturb approximately 33 acres in Garfield County and the proposed staging areas/contractor/pipe yards will disturb 29 acres. Total disturbance in Garfield County is 62 acres. 1.3.4 Contractor/Pipe Storage/Offloading Yards EnCana proposes to use contractor and pipe storage yards on a temporary basis to support construction activities. Both yards are located on property owned by Specialty Restaurants. Maps are included in Attachment 3 in the Narrative Tab. 2 - Collbrnn Pipeline Project May 2008 Pipeline Development Plan 1.3.5 Access Roads EnCana will use existing access roads to gain access to the right-of-way during construction operations. EnCana personnel will utilize Colorado State Highway 6 between Parachute, Colorado and Debeque, Colorado and Garfield County Road 300 to access various points along the pipeline right-of-way. Additionally, multiple private two track roads will also be used by project personnel. No new roads will be constructed. 1.3.6 Aboveground Appurtenances Associated aboveground appurtenances proposed by EnCana include meter stations/valve sets, cathodic protection equipment, and pipeline markers. A meter station/valve set/launcher-receiver will be required at the interconnect to the Orchard Compressor Station. In addition to meters, the meter station 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. 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. 2.0 DEVELOPMENT PLAN REQUIREMENTS 2.1 ATTACHMENTS 2.1.1 Attachments This Development Plan includes the following tabs: • Narrative Tab -Vicinity Map and Route Maps - Alignment Sheets - Yard Exhibits • Plan of Development - Biological Resources Protection Plan - 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 Collbran Pipeline Project Maj 2008 Pipeline Development Plan -Safety Plan -Stormwater Management Plan -Strength Testing Plan - Transportation Management Plan -Waterbody Crossing and Protection Plan • Landowners -Line List -Agreements - Notifications • Specifications -Construction Specifications - Una Bridge Engineering Recommendation • Emergency Response -EnCana Emergency Response Plan - Collbran Pipeline Emergency Response Plan • Resource Surveys -Wildlife Impact and Sensitive Area Report (Pipeline) -Integrated Vegetation and Noxious Weed Management Plan (Pipeline) -Cultural Resources Inventory Report (Pipeline) - Cultural Resource Inventory Report (Yards) -Habitat Assessment (Yards) • Permits -BLM ROW Grant -NWP 12 Preconstruction Notification -CDPHE Constriction Emissions - CDPHE Stormwater -CDPHE MINDI -Garfield County Utility Permit 2.2 CONSTRUCTION SCHEDULE Construction activities are tentatively scheduled for July 2008 and will continue through the fall/winter of 2008. Working hours will normally range from 7:00 AM to 5:00 PM Monday through Saturday. Construction activities will take approximately 6 months and will begin upon approval from the Garfield County Planning Director and the BLM Authorized Officer. 4 Collbran Pipeline Project Mn • 2008 Pipeline Development Plan 2.3 CONSTRUCTION METHODS 2.3.1 Plan of Development EnCana has developed a Plan of Development, which describes construction methods and measures to be taken by EnCana during construction, operation, and maintenance of the project. The Plan of Development is provided to project personnel to establish guidelines for construction and operation of the project and to address mitigation measures that were identified in the Wildlife Impact and Habitats Assessments, Weed Management Plan, and Environmental Assessment. 2.3.2 Construction Sequence The following section provides a description of each phase of standard construction during the project. The following operations are typical in a construction spread. 2.3.3 Project Area Surveying and Staking 2.3.3.1 Pre -Construction Pre -construction surveys and literature review will be conducted to identify sensitive resources along the project route. Resources identified include: sensitive wildlife (e.g., mule deer, elk, and raptor) populations and habitat; sensitive plant populations; and cultural and paleontological resources. Prior to construction, final pre -construction surveys for noxious weed infestations and nesting raptors will be conducted in spring 2008 along the construction workspace. The field survey results will be used to identify sensitive resource construction buffer areas and areas requiring special protective signing, flagging, or fencing. 2.3.3.2 Construction Civil 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. 2.3.4 Clearing, Grading, and Topsoiling Fences crossing the construction workspace will be braced, cut, and temporarily fitted with gates to permit passage. Prior to cutting or replacing the fences, EnCana will notify the grazing pemrittees 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. Col/bran Pipeline Project i May 2008 Pipeline Development Plan Vegetation will be cleared and the construction workspace 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 hydro -axe or similar equipment. Trees and brush will be cut as close to the ground as possible. Vegetative material will typically be chipped or shredded and incorporated into the topsoil. Stumps that are not shredded or chipped and incorporated into the topsoil will be removed and disposed of at an approved disposal facility. Topsoil will be salvaged where required by the BLM and fee -landowners and protected along most of the pipeline route to facilitate revegetation of the construction workspace after construction is complete. Topsoil will be segregated using one of the following methods: from either the full -work area, from the trenchline only, or from the trenchline and working side of the construction workspace. On any lands requiring grading, the topsoil will be stripped from the entire portion of the construction workspace that requires grading. On BLM lands, all available topsoil up to a depth of 6 inches will be removed from the trenchline and working side of the workspace. On any lands requiring grading, the topsoil will be stripped from the entire portion of the workspace 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 construction workspace or a portion thereof. On any lands requiring grading, the topsoil will be stripped from the entire portion of the construction workspace that requires grading. Up to 12 inches of topsoil will be stripped across the full -width of the construction workspace in irrigated agricultural lands. Fee -landowner requirements are listed in the Fee -Lands Line List included as Attachment 2. Topsoil will be stockpiled separate from subsoil and will not be used to pad the trench or construct trench breakers. Dry drainages or washes that cross the construction workspace will not be blocked with topsoil or subsoil piles. Topsoil and subsoil will be placed on the banks of the drainage. Gaps will be left periodically in the topsoil and subsoil windowed to avoid ponding and excess diversion of natural runoff during storm events. 2.3.5 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. 6 Collbran Pipeline Project Alay 2008 Pipeline De'e(opulent Plan 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 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 construction workspace 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 construction workspace 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 construction workspace. 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 Collbrnn Pipeline Project May 2008 Pipeline Development Plan stored in flowing waterbodies and dry drainages or washes that cross the construction workspace 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. 2.3.6 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. 2.3.6.1 Stringing Line pipe will be shipped directly from the manufacturer by rail to pipe yards and then hauled by stringing trucks to the pipeline construction workspace. 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 construction workspace. 2.3.6.2 Bending After the joints of pipe are strung along the ditch, 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 will be installed. 2.3.6.3 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. 2.3.6.4 Welding 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. 2.3.7 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 8 Conran Pipeline Project May 2008 Pipeline Development Plan will be visually inspected and tested with an electronic detector, and any faults or scratches (holidays) will be repaired. 2.3.8 Lowering -in and Padding Once the pipe coating operation has been completed, a section of the pipe will be lowered into the ditch. Padding or placement of sand bags along the bottom of the trench line may occur before the pipe section is lowered -in, depending on the bottom surface of the trench. Side -boom tractors will be used to simultaneously lift the pipe, position it over the ditch, and lower it in place. Inspection will be conducted to verify that minimum cover is provided; the trench bottom is free of rocks, debris, etc.; external pipe coating is not damaged; and the pipe is properly fitted and installed into the ditch. Specialized padding machines will be used to sift soil fines from the excavated subsoil to provide rock -free pipeline padding and bedding. In rocky areas, padding material or a rock shield will be used to protect the pipe. Topsoil will not be used to pad the pipe. 2.3.9 Backfillinq 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 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. 2.3.10 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 as described in the Strength Testing Plan. Collbran Pipeline Project 9 May 2008 Pipeline Derelopmenl Plan Test water will be discharged to approved locations in accordance with applicable permit requirements. 2.3.11 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 construction workspace 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 Stormwater Management Plan. Restoration seeding will be performed in accordance with fee -landowner and BLM requirements as described in the Reclamation Plan. 2.3.11.1 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 construction workspace to block use of the reclaimed construction workspace by motor vehicles in selected areas. Any rocks removed from the construction workspace 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 construction workspace. Layer rock on the surface of erodible soils in critical areas to reduce erosion and restore appearance of native surface. - Apply mulch, erosion control matting, or equivalent measures on steep slopes in accordance with the Stormwater Management Plan. • 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 10 Callbrnn Pipeline Project May 2008 Pipeline Development Plan 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. • Install erosion control measures in accordance with the Stormwater Management 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 of the Plan of Development Narrative, included in the Plan of Development Tab. 2.3.12 Road Crossings and Installation The proposed Collbran Pipeline will be installed across Garfield County Road 300 and several private two -track roads. As determined during a field visit with Jake Mall on March 25, 2008, EnCana will open -cut County Road 300 and will install a concrete culvert with steel grate along the south side of CR 300 to provide a intake for stormwater and allow a wider area for trucks to make the comer. The proposed pipeline will be buried at least 60 -inches underneath the road surface to ensure proper protection of the pipeline. EnCana will submit a utility permit to the Garfield County Road and Bridge Department prior to the start of construction activities. Field notes from the onsite visit are included in the Garfield County Utility Permit section of the Permits Tab. 2.3.13 Drainage and Stream Crossings/Installation The Collbran Pipeline was routed to avoid major drainage and stream crossings. The proposed pipeline will be constructed across four intermittent waterbodies (Little Alkali Creek, Wallace Creek and two unnamed tributaries to the Colorado River) and one perennial waterbody (the Colorado River). EnCana will comply with the general terns and conditions of the Army Corps of Engineers Nationwide General Permit number 12, included in the NWP 12 Preconstruction Notification section of the Permits Tab. Collbran Pipeline Project Moy 2008 Pipeline Development Plan The Colorado River will be crossed by suspending the pipeline on an existing Garfield County span bridge (the old Colorado River Bridge also referred to as the Una Bridge). EnCana will suspend the pipeline in accordance with all applicable Garfield County permit requirements. Remaining waterbodies will be crossed using the open -cut crossing method. Trackhoes will excavate a trench in the 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 ten 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 (if flow is present). 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. Dry drainage crossings will be constructed using the same upland, mainline construction methods that will be used along the rest of the construction workspace, except that spoil will be placed outside the channel. During cleanup and reclamation, the pre -construction profiles and contours (including meanders of the drainage bed) of dry drainages will be re-established. Mulch, seed, and erosion control measures will be installed as described in the Waterbody Crossing and Protection Plan and the Stormwater Management Plans included in the Plan of Development Tab. 2.3.14 Una Bridge Crossing EnCana plans to span the Colorado River by installing the pipeline across the Una Bridge (similar to the three existing pipelines that EnCana installed between 2003 and 2005). The engineering report and recommendations is included in the Una Bridge Engineering Report section of the Specifications Tab. EnCana would like to purchase the Una Bridge and is preparing an offer to present to Garfield County. 12 Collbrnn Pipeline Project May 2008 Pipeline Development Plan 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—Grand Junction Field Office Right -of -Way Grant Pipeline right-of-way EA preparation NEPA compliance Department of Defense Sacramento District 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 Quafty Control Division Construction Emissions Permit Construction of land development projects greater than 25 acres Department of Public Health and Environment Water Quality Control Division Construction Stormwater Permit Discharge of stormwater from construction site Minimal Industry Discharge Permit Discharge of hydrostatic test water and discharge of groundwater from construction site Local -Colorado Garfield County Pipeline Development Plan Installation of pipelines Utility Installation Permit Crossing of County roads and rights-of-way Copies of the permits are included in the Permits Tab. 2.5 OWNERSHIP AND FEE -LANDOWNER DOCUMENTATION 2.5.1 Ownership 2.5.1.1 Affected Landowners Approximately 95 percent of the proposed pipeline is located on fee surface and the remaining 5 percent is located on land administered by the Bureau of Land Management Glenwood Springs Office. Garfield County Assessor Maps depicting the pipeline route are provided in the Landowners Tab. The affected landowners are the BLM, Keinath, Colohan Family Trust, and Tipping et al. Contact information for the fee -landowners are provided in the Landowners tab. Specialty Restaurants is also an affected landowner because both staging areas/pipe/contractor yards are located on property owned by Specialty. Collbrnn Pipeline Project May 2008 Pipeline Development Plan 2.5.1.2 Adjacent Landowners There are two Landowners that are within 200 feet of the proposed pipeline (Jolly and Strong) and one landowner that is within 200 feet of the proposed staging area/pipe/contractor yards (CDOT) that are not affected surface owners. Contact information for each adjacent landowner is included in the Landowners Tab. EnCana will provide notice to these landowners within seven days of submitting the Pipeline Development Plan to the County. Return receipt providing notification to each adjacent landowner will be provided upon receipt. 2.5.2 Agreements EnCana did not determine if the surface owners are party to the mineral lease and is instead providing copies of all surface use agreements with affected landowners. Copies of the agreements are provided in the Landowners Tab. 2.5.3 Buildings There is one building located within 350 feet of the proposed project. This is a metal building used as a barn on the Colohan property.

Copies of resource surveys are included in the Resource Surveys Tab. Please note that biological surveys were completed in the fall of 2007 and will be completed in spring 2008 prior to construction. If survey results differ from 2007, EnCana will submit the new information to the County. 2.7.1 Biological EnCana consulted with the BLM, Colorado Division of Wildlife (CDOW), and the U.S, Fish and Wildlife Service to identify wildlife species of concern and field surveys were conducted in the summer and fall of 2007 to determine the presence or absence of suitable habitat for species of concern. Ten species of wildlife of special concern to Garfield County were identified that may Collbran Pipeline Project May 2008 Pipeline Development Plan have the potential to seasonally use areas within or adjacent to the pipeline corridor. These species and potential impacts are identified in the following table: Wildlife Species of Special Interest in Garfield County Species Impact Bald Eagle None expected. Black Bear None expected. Brazilian Free -tailed Bats None expected. Canada Goose None expected. American Elk None expected with adherence to timing limitations and proper reclamation. Great Blue Heron None expected. Mule Deer None expected with adherence to timing limitations and proper reclamation. American Peregrine Falcon None expected. Razorback Sucker None expected. Wild Turkey None expected. The project will not affect any federally listed threatened or endangered species. EnCana will adhere to the BLM recommendations to avoid construction activities between December I and April 30 in big game wintering habitat. If nesting raptors are found during construction, EnCana will adhere to buffer zones and timing limitations as recommended by the BLM. Depending on the species, buffer zones are typically 0.25 to 0.5 miles wide and timing limitations would be typically between March 1 and August 15. 2.7.2 Paleontological There are no paleontological outcrops in Garfield County that require mitigation. 2.7.3 Cultural Several cultural sites were identified within or near the proposed pipeline corridor. The BLM has not identified the locations of cultural resource sites along the project route and it is unknown whether any of these sites occur within Garfield County. EnCana will adhere to BLM recommended mitigation for these areas. 2.8 REVEGETATION Seeding and reclamation activities will begin after final clean-up activities have been completed in the fall of 2008. Disturbed areas will be reseeded with the approved fee -landowner and BLM seed mixtures. EnCana will only use seed that is certified weed -free. Seed bag tags will be collected and submitted to the BLM within 30 days of seeding for the sections of the project on BLM lands and the sections of the project on private land will be submitted to the Garfield County Vegetation Manager at the completion of the project. Seeding rate will be listed as pounds per acre of pure live seed (PLS). The following seed mix was recommended by WestWater Engineering in the Integrated Vegetation and Noxious Weed Management Plan 16 Collin -an Pipeline Porojeet May 2008 Pipeline Development Plan (included in the Resource Surveys Tab) and is subject to change based on recommendations from the BLM or final landowner requirements. Recommended Seed Mix Species (Common) Species (Scientific) Variety Seeding Rate (PLS*/a) Plant the following: Indian ricegrass Achnatherum (ayzopsis) hymenoides Nezpar, Paloma, Rimrock 1.3 Galleta Pleuraphis (Hilaria) jamesii Viva florets 1.7 Bluebunch wheatgrass Agropyron spicatum Secar, P-7, Anatone 1.9 and one of the following: Thickspike wheatgrass Agropyon dasystachyum Critana, Schwendimar 2.3 Slender wheatgrass Agropyron trachycaulum San Luis 2.3 Western wheatgras Arriba 2.0 and two of the following: Muttongrass Poa fendleriana 0.4 Sandberg bluegrass Poa sandbergii 0.4 Bottlebrush squirreltail Elymus elymoides 1.8 *Pure Live Seed Total up to 14.1 The right-of-way will be scarified, tilled, harrowed, or roughened to a depth of 3 to 4 inches prior to seeding, where needed, to prepare the seedbed and improve revegetation potential. 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. Broadcast seeding will be employed only in areas where drill seeding is unsafe or physically impossible. Broadcast application rates will be double the drill rate. Immediately after broadcasting, the seed will be uniformly raked, chained, or dragged to incorporate seed to a sufficient seeding depth. EnCana will provide a revegetation security to Garfield County for the amount of $154,250 or $2,500 per acre of disturbance (61.7 acres) for the Collbran Pipeline Project. 2.9 WEED MANAGEMENT PLAN Noxious weed surveys were completed by WestWater Engineering Inc. for the proposed Collbran Pipeline Project and by Wildlife Specialties for the proposed contractor/pipe/staging areas. Six species on the Garfield County or State of Colorado weed list were observed along the Collbran Pipeline project area; however, the vegetative community does not support extensive noxious weed infestations except for cheatgrass. Salt cedar and cheatgrass were observed in the contractor/pipe/staging areas. EnCana will control and reduce the spread of noxious weeds by implementing the following mitigation measures: Collbran Pipeline Project May 2008 Pipeline Development Plan Ensure that equipment used on the project is clean and free of noxious weeds before arriving at the project. Cleaning will be completed using either high-pressure water or compressed air to remove potential weed seeds. Minimize soil disturbance to reduce areas of potential noxious weeds. Equipment and project vehicles will be confined to the flagged project right-of-way to minimize excess soil disturbance. • Salvage and segregate topsoil, then redistribute to reclaim the right-of-way. • Establish native grasses and forbs. Refer to Section 2.8 for a discussion on reclamation and seed mixes. • Eradicate weed introductions early through the uses of herbicides. Herbicides will only be applied by personnel that are licensed by the State of Colorado to use and apply herbicides. The Integrated Vegetation and Noxious Weed Management Plan and Habitat Assessment are included in the Resource Surveys Tab. 2.10 EMERGENCY RESPONSE The following table lists contact information for emergency personnel: Emer_r enc Phone Numbers Utility Notification Center of CO (800) 922-1987 Garfield County Sheriff (970) 625-8095 Parachute Fire Department 911 or (970) 285-7711 Parachute Police Department 911 or (970) 285-7630 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 provided in the Emergency Response Tab. Detailed safety measures and notification protocols are presented in EnCana's Fire Prevention and Suppression Plan, Strength Testing Plan, and Safety Plan. These plans are included in the Plan of Development Tab. After EnCana selects a construction contractor (early June), a detailed plan will be sent to the County and the construction contractor representatives will meet with representatives from the Sheriff's department and Grand Valley Fire District. EnCana will reimburse the appropriate emergency service provider for costs incurred in connection with emergency response for activities associated with this project. 18 Conran Pipeline Project May 2008 Pipeline Development Plan 2.11 TRAFFIC IMPACT EnCana will utilize Garfield County Road 300 and several private roadways within Garfield County to gain access to the right-of-way during construction. Garfield County Road 300 is heavily used by the oil and gas industry, and minimal impact will result from the increase traffic volumes. Vehicle traffic on Garfield County Road 300 will be necessary for approximately 2 to 3 months of the project, since the majority of the project is located in Mesa County and construction crews will utilize other roadways in Mesa County to gain access to the right-of-way. The table below provides an estimate of the traffic impacts on Garfield County Road 300. 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 300 and US Highway 6. The 75 commuter trips will be from I-70 to the temporary construction yard located at the southwest intersection of County Road 300 and Highway 6. The following table depicts average (over the course of the project) estimated traffic numbers from the construction yard south along County Road 300 to the pipeline workspace: Traffic Impacts Vehicle Type and Number Roundtrips (yard to pipeline) Totals Buses -4 1 4 .-- ' Com' Pick-up Trucks -40 1 40 Lowboys -2 5 10 ---_, 3 G:.rv- Grease truck -1 3 1 3 Fuel Truck -1 3 t 3 Winch Truck -1 10 .10 -3 c . Stringing Trucks -8 10 80 -•--r 3 c,,,...„- .e Total 150 i 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. 2.12 STAGING AREAS/CONSTRUCTION YARDS EnCana will use an office and equipment staging areas/yard and a pipe storage staging areas/yard on a temporary basis to support construction activities. The proposed office and equipment yard is approximately 7 acres and the proposed pipe storage yard is approximately 22 acres. Both yards are located on Specialty Restaurants. Collbran Pipeline Project May 2008 Pipeline Development Plan Electricity and telephone lines will be installed at the temporary construction offices. Portable toilets will be available on-site and potable water will be transported from off-site and made available to construction personnel. Access to the office and equipment staging area is off of Garfield County Road 300. EnCana will apply for a driveway permit prior to construction. Access to the pipe storage staging area is off of U.S. Highway 6 and will be from an existing driveway that EnCana utilizes to access the C7OU well pad. 2.13 HYDROTEST WATER The Collbran Pipeline will be hydrostatic tested with water prior to being placed into service. EnCana has existing agreements for appropriating water from the Colorado River. 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 in accordance with the CDPHE MINDI permit requirements. EnCana does not anticipate discharging hydrostatic test water within Garfield County. Additional information on hydrostatic testing activities is provided in the Strength Testing Plan included in the Plan of Development. 3.0 POST -CONSTRUCTION ACTIVITIES 3.1 MAINTENANCE AND OPERATION EnCana will maintain the right-of-way for the life of the project. Maintenance will include repairing soil erosion and reseeding as necessary. The right-of-way will be considered satisfactorily reclaimed by the BLM Authorized Officer, fee -owner, and the Garfield County Vegetation Management personnel when soil erosion has been stabilized and a vegetative cover at least equal to that present prior to disturbance and a plant species composition at least as desirable as that present to the disturbance is established. Establishment of all the species in the seed mixture will be considered as meeting the composition/desirable species criteria. EnCana will monitor the right-of-way for noxious weed infestations and shall control noxious weeds as requested by the BLM Authorized Officer and Garfield County Vegetation Management personnel. Herbicide use shall be approved by the BLM Authorized Officer prior to use. EnCana's gathering system is operated according to natural gas industry standards. Supervisors and field personnel will monitor and control the system by driving throughout the project area inspecting facilities on a periodic basis. Disposal of any liquid and solid waste generated during maintenance and operation of the pipeline will be done at an approved facility in an environmentally sound and approved manner. 20 Conran Pipeline Project May 2008 Pipeline Development Plan 4.0 DEVELOPMENT PLAN REVIEW STANDARDS 4.1 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. 4.2 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 meters 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. 4.3 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. Because the pipeline corridor parallels an exiting pipeline or road corridor, 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 Tab. EnCana will: • Restore the right-of-way to as near as possible original contours and restore natural drainage and runoff patterns. • 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. Collbran Pipeline Project May 2008 Pipeline Development Plan 4.4 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. • 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 Tab. • Maintain unsurfaced roads during construction of the project. • Restore roads to equal or better condition than pre -construction levels after construction is complete. 4.5 ENDANGERED SPECIES This project will not threaten any endangered species. Please refer to Section 2.7.1. 4.6 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 22 Collin on Pipeline Project May 2008 Pipeline Development Plan 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. • 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 Tab. 4.7 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, Waterbody Crossing and Protection Plan, and Strength Testing Plan in the Plan of Development Tab. EnCana will: • Install temporary equipment bridges across flowing waterbodies. Collbrnn Pipeline Project May 2008 Pipeline Development Plan • 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. • 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. • hrstall 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. 24 Col@ran Pipeline Project May 2008 Pipeline Development Plat 4.8 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. 4.9 RECLAMATION PLAN Please refer to the discussion on reclamation in Section 2.8. 4.10 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.

(EnCana) and its contractors (Contractor) during constniction, operation, and maintenance of the Collbran 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 construction workspace, access roads, temporary use areas, and other areas used during construction of the project. This plan will be developed as the implementing document for relevant mitigation measures contained in the Environmental Assessment and may be updated prior to construction to ensure that all mitigation measures have been included. 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. In addition, the following environmental compliance plans are attached to the Plan of Development as appendices. The following is a list of the compliance plans: • 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 Column, Pipeline Project August 2007 Plan of Development • Appendix 10—Safety Plan • Appendix 11—Stormwater Pollution Prevention Plan • Appendix 12—Strength Testing Plan • Appendix 13—Transportation Management Plan • Appendix I4—Waterbody Crossing and Protection Plan 1.3 Required Permits The project traverses several jurisdictional boundaries, including federal, state, and local agencies.

The project will involve the construction and operation of approximately 22 miles of 24 -inch diameter buried natural gas pipeline and related aboveground appurtenances in Garfield and Mesa Counties, Colorado. 2.1 Purpose and Need EnCana plans to increase production in the Collbran/Plateau Valley area by approximately 50 to 100 million standard cubic feet per day (mscfd), each year, for the next several years. The Collbran Pipeline Project will provide a natural gas gathering system that will transport the projected future volumes of natural gas from the western slope of Colorado and the Rocky Mountain region to major interconnections with interstate pipelines. The proposed pipeline will transport approximately 650 mscfd of natural gas from the Collbran/Plateau Valley area of western Colorado to the Meeker Gas Plant in Rio Blanco County for processing. The pipeline has been sized to accommodate EnCana's current and future estimated gas production and has been designed to accommodate existing and future natural gas from other natural gas producers in the Collbran/Plateau Valley area. This pipeline will transport untreated gas to a central processing facility (Meeker Gas Plant) and will provide other producers an opportunity to transport their gas to the Meeker Gas Plant. This will allow other producers to transport their gas out of the Collbran/Plateau Valley without installing gas treatment and processing facilities. Natural gas liquids would be transported via existing pipeline from the Meeker Gas Plant to the MAPCO pipeline in Utah and the processed natural gas would he delivered to the Entrega/Rockies Express Pipeline or other interstate pipeline sales outlets. The proposed pipeline would be one of the outstanding pieces in EnCana's Piceance Basin strategy. In 2005, EnCana received a permit from the BLM (COC -67980) to construct and operate a 1.6 billion standard cubic feet of gas per day natural gas processing facility and 205 miles of natural gas, natural gas liquids, and water pipelines to and from the processing facility. EnCana's Piceance Basin Strategy, maximizes processing technology and minimizes the number of processing facilities, land disturbance, noise, and truck traffic, by constructing and utilizing existing off -specification gas pipelines throughout the Piceance Basin to deliver unprocessed gas to a central processing facility, the Meeker Gas Plant owned by Enterprise. The Meeker Gas Plant will have pipelines that deliver natural gas liquids to an existing natural gas liquids pipeline in Utah and that deliver residue gas to intrastate pipeline sales outlets. EnCana's existing and planned pipeline infrastructure allows EnCana and other natural gas producers the opportunity to transport unprocessed natural gas from natural gas fields in Rio Blanco, Garfield, and Mesa Counties without having to construct additional treatment and processing facilities. Collbran Pipeline Project .it uguct 2007 Plan of Development 2.2 Pipeline Facilities 2.2.1 Description The proposed project is approximately 22 miles of up to 24 -inch diameter natural gas pipeline and related aboveground facilities. The project route is depicted in Attachment 1. The pipeline 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 Construction Workspace The nominal construction workspace width will be 75 feet. Following construction of the pipeline, the construction workspace will be reduced to a permanent construction workspace width of 50 feet. The proposed pipeline will generally be installed at the edge of existing pipeline or road corridors, and will use a standard 25 -foot offset from the existing pipelines when located adjacent to a pipeline corridor. At certain locations, the proposed route deviates from this standard offset configuration due to terrain and/or environmental features. Approximately 20.3 miles of the 21.8 mile pipeline corridor (93 percent) parallels existing pipeline or road corridors. The approximately 1.5 miles of pipeline corridor that does not follow existing corridors was routed to avoid areas on the Grand Mesa National Forest that had erosive soils, susceptivity to flash flooding, bighorn sheep habitat and sensitive plant habitat. EnCana will utilize temporary use areas where additional construction workspace width will be required at drainage crossings and steep side and ascent -descent slopes. These areas are presented in the following table: 4 Collbran Pipeline Project A lig fist 2007 Plan of Development Temoorar Milepost Reason Needed Length (feet) Width (feet) Total (Acres) 0.3 drainage 306 25 0.20 1.4 side slope 438 25 0.27 2.3 side slope and drainage 781 25 0.44 3.0 side slope and drainage 516 25 0.29 3.1 side slope and drainage 308 25 0.15 4.1 drainage 566 50 0.67 4.5 side slope and drainage 498 25 0.28 4.6 side slope and drainage 594 50 0.72 4.8 side slope 390 25 0.22 5.0 side slope and rock outcrop 258 25 0.15 5.1 side slope 421 25 0.21 6.0 side slope 275 25 0.14 6.1 steep topography, side slope, drainage 3060 50 3.43 8.2 side slope 541 25 0.31 9.1 side slope 790 25 0.45 10.3 side slope 1031 25 0.59 10.7 side slope 1 191 25 0.66 17.8 side slope 475 25 0.28 18.3 drainage 262 25 0.16 19.1 side slope 974 25 0.55 19.9 drainage 471 25 0.27 10.44 2.2.3 Ancillary Facilities 2.2.3.1 Access Roads EnCana will use existing roads to gain access to the construction workspace during construction. These access roads are primarily gravel and/or dirt roads utilized during installation of the existing Kinder Morgan, Momentum, Laramie, and EnCana pipelines. 2.2.3.2 Contractor/Pipe Storage/Offloading Yards EnCana proposes to use contractor, pipe storage, and off-loading 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/valve sets, cathodic protection equipment, and pipeline markers. Meter stations/value sets will he 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 meter C'ollbran Pipeline Project Augur! 2007 Plan "1 Development stations/valve sets would require no more than a maximum land requirement of 50 feet in width by 50 feet in length. The perimeter of the facility will be surrounded with suitable security fencing. EnCana plans to install three meter station/valve set. One will be installed near milepost 6.1 to accommodate potential future gas volume from potential future interconnects with TransColorado. The other meter station/valve sets are planned near milepost 11.7 and milepost 14.1 and would accommodate potential future gas volume from EnCana's Orchard Unit gathering system. 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 2008. Construction activities are anticipated to last 6 months. 3.0 CONSTRUCTION ACTIVITIES The following section provides a description of each phase of standard construction along the construction workspace. 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 will be conducted to identify sensitive resources along the project route. Resources identified include: sensitive wildlife (e.g., mule deer, elk, and raptor) populations and habitat; sensitive plant populations; and cultural and paleontological resources. Mitigation measures intended to minimize itnpacts are provided in environmental compliance plans included in this document (e.g., Reclamation Plan, Waterbody Crossing and 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 2008 along the construction workspace 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 surveys will be performed by EnCana to identify the centerline of the pipeline and the 6 Collbran Pipeline Project August 2007 Plan DJ Ilerelopmeii1 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 construction workspace 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 workspace 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 he 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 hydro -axe or similar equipment. Trees and brush will be cut as close to the ground as possible. Vegetative material will typically be chipped or shredded and incorporated into the topsoil. Stumps that are not shredded or chipped and incorporated into the topsoil will be removed and disposed of at an approved disposal facility. Topsoil will be salvaged where required by the BLM and fee -landowners and protected along most of the pipeline route to facilitate revegetation of the construction workspace after construction is complete. Topsoil will be segregated using one of the following methods: from either the full -work area, from the trenchline only, or from the trenchline and working side of the construction workspace. On cnn' lands requiring grading, the topsoil will be stripped from the entire portion of the construction workspace that requires grading. On BLM lands, all available topsoil up to a depth of 6 inches will be removed from the trenchline and working side of the workspace. On any lands requiring grading, the topsoil will be stripped from the entire portion of the workspace 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 construction workspace or a portion thereof. On any lands requiring grading, the topsoil will he stripped from the entire portion of the Collbron Pipeline Pwie ! 7 it unnsi 2007 Plan of Development construction workspace that requires grading. Up to 12 inches of topsoil will be stripped across the full -width of the construction workspace in irrigated agricultural lands. Fee -landowner requirements are listed in the Fee -Lands Line List included as Attachment 2. Topsoil will be stockpiled separate from subsoil and will not be used to pad the trench or construct trench breakers. Dry drainages or washes that cross the construction workspace will not be blocked with topsoil or subsoil piles. Topsoil and subsoil will be placed on the banks of the drainage. Gaps will be left periodically in the topsoil and subsoil windowed to avoid ponding and excess diversion of natural runoff during storm events. 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 workspace. • Protect all survey monuments found within the construction workspace. Survey monuments include, but are not limited to, General Land Office and BLM Cadastral Survey Corners, 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 construction workspace 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 hydro -axe or similar equipment as close to the ground as possible. • Use non-linear construction workspace clearing techniques (feathering) to minimize visual impacts, where feasible. 8 Collbran Pipeline Project August 2007 Place of Uerelopment • Shred or chip trees and 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 lands—up to 6 inches across the trenchline and working side of the construction workspace. - 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 construction workspace. - Any areas requiring grading—up to 6 inches across the entire construction workspace. • 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 construction workspace 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 Stormwater Management 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. A typical trench will he excavated approximately 36- to 48 -inches wide at the bottom and the Cullhrzm Pipeline Project Ang¢v 2007 Plan of Development 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 construction workspace 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 Calf" 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 construction workspace 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 construction workspace. 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 construction workspace 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. 10 Collbmn Pipeline Project August 2007 Plan of Development 3.3.1 Trenching Requirements The Contractor will implement the following mitigation treasures 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 construction workspace 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 construction workspace 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 construction workspace 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 construction workspace. Each individual joint of pipe will be unloaded with a sideboom or trackhoe fitted with a vacuum device and placed (strung) paralld 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 construction workspace. Cu/1/,, n Pipeline Riojet-t I I A ugtat 2007 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 12 Col/bran Pipeline Project August 2007 Plan of Development 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. 3.5.1 Backfilling Requirements The Contractor will implement the following mitigation measures during backfilling operations: • Construct trench breakers in accordance with the Stormwater Management 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 as described in the Strength Testing Plan. Test water will he 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. Collbran Pipeline Project Augnsr 2007 Plat o rDerelopment • 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 construction workspace 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 Stormwater Management 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 construction workspace to block use of the reclaimed construction workspace by motor vehicles in selected areas. Any rocks removed from the construction workspace 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 construction workspace. 14 Collbruu Pipeline Project August 2007 Plurt 0f Derelupmen! - Layer rock on the surface of erodible soils in critical areas to reduce erosion and restore appearance of native surface. - Apply mulch, erosion control matting, or equivalent measures on steep slopes in accordance with the Stormwater Management Plan. • 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. • Install erosion control measures in accordance with the Stormwater Management 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. 3.8 Livestock Barrier and Other Livestock Issues Fences crossing the construction workspace 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 he 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 Collbmn Pipeline Project 15 August 2007 Plan of Development 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 workspace. • Maintain the current condition and usability of stock ponds and other facilities along the construction workspace. • 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 construction workspace 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: • Comply with requirements listed in the Safety Plan, Fire Prevention and Suppression Plan, Blasting Plan, and Strength Testing 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 construction workspace. • 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 16 Collbrmr Pipeline Project August 2007 Plan of -Development construction workspace 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 construction workspace. 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. • Remove human wastes, temporarily located within self-contained facilities (portable toilets), from the construction workspace 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, and will operate and maintain the pipeline in accordance with industry standard procedures to ensure safe operation and to maintain the integrity of the 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 Access Surface travel along the construction workspace will generally he limited to periodic valve inspections, leak surveys, construction workspace maintenance, and any pipeline repairs that may be needed. In addition to the above activities, it will also he necessary to access the construction workspace 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. Cnllbrun Pipeline Project Aq,mn 21)07 17 Plan of Development 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 external mechanical damage to pipe and coating material can be made without interruption or with minimum interruption of service. Repairs are usually made Linder 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 construction workspace. 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 construction workspace 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. EnCana will be responsible for noxious weed control on disturbed areas within the limits of the construction workspace. 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 18 Collbron Pipeline Project August 2007 Plan of Development 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 EMERGENCY PROCEDURES EnCana will develop an Emergency Plan for DOT regulated pipelines that will be followed by EnCana employees in the event of an emergency. The Emergency Plan will be developed in accordance with applicable 49 CFR Parts 191 and 195 requirements and will include written procedures that have been used to minimize the hazards of natural gas and natural gas liquids pipeline emergencies. The Emergency Plan will address topics- such as administrative issues, emergency planning, assignment of responsibilities, handling and evaluating emergency calls, responding to and controlling emergency situations, news media communications, restoration of service, obtaining and reporting emergency information, employee training, liaison with public officials, general public information program, location/inventory of pipeline repair materials and equipment, and lists of emergency telephone numbers and key personnel. 6.0 TERMINATION AND ABANDONMENT OF CONSTRUCTION WORKSPACE AND FACILITIES Prior to termination of the BLM Construction workspace Grant, or any portion thereof, EnCana will contact the Authorized Officer to arrange for a pre -termination meeting and joint inspection of the construction workspace. 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 construction workspace in accordance with the termination plan.

(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 construction workspace, 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 will be developed as the implementing document for relevant mitigation measures contained in the Environmental Assessment and may be updated prior to construction to ensure that all mitigation measures have been included. 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 Collbran Pipeline Project August 2007 Blasting Plan governing the storage of explosives. All powder magazines will be located in a secure remote 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, 2 Collbian Pipeline Projee( August 2007 Blasting Plan and equipment are out of the danger zone. Blasting will not be used where there are identifiable risks due to the proximity of residerices 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" warning 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 Colhran Pipeline Project August 2007 Blasting Plan possibility of damage due to fly -rock, shock waves, vibrations, or changes to hydraulic 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 Collbran Pipeline Project August 2007 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 construction workspace, 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 and defines measures to preserve and protect cultural resources during construction of the project. This plan will be developed as the implementing document for relevant mitigation measures contained in the Environmental Assessment and may be updated prior to construction to ensure that all mitigation measures have been included. 2.0 PRE -CONSTRUCTION ACTIVITIES 2.1 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. 2.2 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 construction workspace 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). 3.0 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 Collbran Pipeline Project August 2007 Cullum! Resources Protection Plan after the unexpected discovery of any cultural materials. 3.1 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 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. 3.2 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. 4.0 DISCOVERY REQUIREMENTS 4.1 Cultural Resources If cultural resources (artifacts, hearths, rock art, etc.) are discovered Contractor will immediately stop all work near the discovery. The implemented when cultural resources are discovered: • Cease all earth disturbing activity within 100 feet of the discovery. until notified to proceed from the BLM Authorized Officer. during construction, the following steps will be The area will be secured • Contact the BLM Authorized Officer, Environmental Inspector, and Cultural Monitor 2 Collhran Pipeline Project August 2007 Cultural Resources Protection Plan 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 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. 4.2 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.

(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 construction workspace, 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 (BLM). The purpose of the environmental compliance program is to monitor and document the implementation of mitigation measures included in the Environmental Assessment. This plan will be developed as the implementing document for relevant mitigation measures contained in the Environmental Assessment and may be updated prior to construction to ensure that all mitigation measures have been included. 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 (EI) 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 Cotlbrat Pipeline Project August 2007 Environmental Compliance Management Plan project representatives (construction, engineering, lands, environmental) Will work jointly to develop and implement responsive resolutions as efficiently as possible. 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 Collbran Pipeline Project August 2007 Environmental Compliance Management Plan 2.1.3 Environmental Inspector An Environmental Inspector (EI) 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 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 CoAAGran Pipeline Project 3 August 2007 Environmental Compliance Management Plan construction -related issues. • Supervise compliance with construction, safety, and environmental mitigation measures identified in the Plan of Development. 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 Biological Monitors At this time there are no requirements for 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 4 Collbran Pipeline Project August 2007 Environmental Compliance Management Pfau 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 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 construction workspace, 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 construction workspace. 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 will be developed as the implementing document for relevant mitigation measures contained in the Environmental Assessment and may be updated prior to construction to ensure that all mitigation measures have been included. 2.0 FIRE PREVENTION MEASURES 2.1 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. 2.1.1 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. 2.1.2 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. Collbran Pipeline Project August 2007 Fire Prevention and Suppression Plan 2.1.3 Spark Arresters During construction, operation, and maintenance of the construction workspace, 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. 2.1.4 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 construction workspace, 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. 2.1.5 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. 2.1.6 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 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. 2.1.7 Refueling Fuel tricks 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. 2.1.8 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. 2 Collbran Pipeline Project August 2007 Fire Prevention and Suppression Plan 2.1.9 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. 2.1.10 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. 2.2 Pipeline Operation and Maintenance During pipeline operation, the risk of fire danger is minimal. The primary causes of fire on the construction workspace result from unauthorized entry by individuals utilizing the construction workspace for recreational purposes and from fires started outside of the construction workspace. In the latter case, the construction workspace 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. 2.3 Aboveground Appurtenances Defensible space will be created around any aboveground appurtenances in accordance with Colorado Firewise guidelines (www.firewise.com). 3.0 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.
