APPLICATION SUBMITTAL REQUIREMENTS As a minimum, specifically respond to all the following items below and attach any additional information to be submitted with this application: Development Plan Submissions: The applicant shall submit eight copies of the proposed development plan with the completed application form to the Planning Director. The following information must be submitted with a development plan application: (1) Vicinity map indicating the section, township, and range of the site, and its relation to surrounding public roads and municipal boundaries. Project maps are provided in Attachment 1. (2) Project Overview: a description of the project including the length of the pipeline, diameter of the pipeline, pipeline commodity, and the general description of the pipeline route. Project Overview EnCana Oil & Gas (USA) Inc. (EnCana) is planning to extend its Tombstone Trunk pipeline. This project involves construction, operation, and maintenance of a new trunk pipeline for gathering and transporting of natural gas from related drilling operations in the Orchard Unit area north and south of Interstate 1-70. The pipeline and related above-ground facilities will be located in Garfield County, Colorado. The Tombstone Phase 3 pipeline is approximately :!::16,641 feet in length and will parallel EnCana's existing 24-inch Parachute to DeBeque pipeline. The proposed route and all construction disturbances will be located within an existing pipeline corridor. The project is located in Sections 5 and 6, Township 8 South, Range 96 West and Sections 32, 33, 28, and 27, Township 7 South, Range 96 West. The pipeline will begin at the E70U lateral in Section 6, Township 8 South, Range 96 West and will end at the existing EnCana pipeline riser located in Section 27, Township 7 South, Range 96 West, just north of the Orchard Compressor Station. The Tombstone Phase 3 pipeline will gather unprocessed natural gas from various Orchard Unit well pad sites and transport the natural gas to the existing EnCana riser for delivery of the natural gas to the Orchard Compressor Station. The proposed project is approximately 3.2 miles of up to 12-inch diameter, .281 wall X52/60 FBE buried, steel or composite, natural gas. The pipeline will be buried at least 48-inches in depth. The estimated maximum allowable operation pressure (MAOP) is 1,440 pounds per square inch (psi) and the pipeline will be operated at a normal operating pressure of 200 to 500 psi. EnCana has submitted a Colorado Department of Transportation (COOT) Utility/Special Use Permit Application requesting permission to construct the 12-inch diameter natural gas pipeline and related above-ground facilities in the COOT right-of-way in Garfield County, Colorado. The permit application is included in Attachment 2. l)EVELOPl\'lENT PL1\N APPLIC1\TION 03/01/2008 TOMBSTONE Pl !ASE 3 PIPELINE (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. Buildings located within 350 feet of the proposed project are 2 storage sheds, 8 garages, 1 office building, and 1 cement building. See Attachment 1 for Garfield County Assessor Map indicating buildings and their location. The project maps provided in Attachment 1 indicate property ownership along the right-of-way. (4) Evidence of surface owner notification and of surface agreements where the surface owner is not a party to the mineral lease. COOT is the only affected landowner. Please note that EnCana did not determine if COOT is party to the mineral lease and will provide a copy of the approved COOT permit when approved. See Attachment 1 for Garfield County Assessor Map, depicting surface owner (COOT) and adjacent landowners. The project is located within 200 feet of eight landowners that are not affected surface owners. The return receipts providing notification to the landowners will be provided upon receipt. Landowner information is provided in Attachment 4. (5) Need for Proposed Action: a statement of the reason for the pipeline. EnCana plans to increase production in the Orchard Unit area by up to 50 million standard cubic feet per day (mscfd), each year, for the next several years. The Tombstone Phase 3 pipeline will complete a natural gas gathering system that will utilize existing pipelines to transport the projected future volumes of natural gas to the Meeker Gas Plant in Rio Blanco County for processing. After processing, 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 pipeline route is within the COOT right-of-way along Highway 6 & 24 and will be installed entirely within the existing, disturbed area. The proposed Tombstone Phase 3 natural gas pipeline would be installed maintaining an 8-foot off-set from the edge of existing pipeline to the edge of proposed pipeline. The average width of the existing, disturbed pipeline corridor is approximately 75 feet. A temporary work area of 60 feet will be used during construction of this project. The right-of-way will revert to a permanent easement of 30 feet. Construction of the proposed pipeline will disturb approximately 22.9 acres. No new disturbance will occur outside the existing, disturbed area. (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 begin after project approval by the Garfield County Planning Department and approval of the COOT Utility/Special Use Permit To Construct Application. Construction activities are anticipated to last 12-16 weeks. Construction activities are tentatively scheduled for May 2008 and will continue through August 2008. Working hours will normally range from sunrise to sunset 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. Westwater Engineering, Inc. (Westwater) has completed the biological assessments of the Tombstone Phase 3 pipeline. The Tombstone Phase 3 pipeline was surveyed for sensitive resources during the fall of 2007. The Sensitive Resource Reports for the Tombstone Phase 3 pipeline are provided in Attachment 5. Biological surveys were completed and it was determined that no significant impact to wildlife would occur. The trunk line is not specifically located on or across any noted wildlife habitat feature previously identified by CDOW or U.S. Fish and Wildlife Service as noteworthy, essential, or critical to any species known for this habitat in this part of the state. Also completed were surveys for federally listed threatened and endangered plants and BLM sensitive species plants along the project right-of-way. No sensitive plant species were observed along the right-of-way. 4 l)EVEJ.OPMl·'.NT PI,AN 1\PPJJCATION 03/01/2008 TOMBSTONE PHASE 3 PIPELINE No cultural or paleontological resources were identified during construction of EnCana's existing Parachute to DeBeque pipeline. The Tombstone Phase 3 pipeline will be constructed within an existing disturbance and will not impact any known cultural or paleontological resources. No wetlands were identified during construction of EnCana's existing Parachute to DeBeque pipeline. The Tombstone Phase 3 pipeline will be constructed within an existing disturbance and will not impact any known wetlands. (11) Land Grant/Permits/Authorizations and Stipulations: attach a copy of any land grants, permits, and authorizations including stipulations. The COOT Utility/Special Use Permit Application has been submitted. A copy of the submittal is provided in Attachment 2. Upon approval of the COOT Application request, a copy will be provided to Garfield County. A copy of the Stormwater Discharge Permit is provided in Attachment 3. (12) Revegetation Plan: a. A plant material list. Be specific, scientific and common names are required. Include application rate in terms of pure live seed (PLS) per acre/. 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. Soil types on the pipeline route support similar species of native vegetation. The following mix is adapted from the seed mix used on the Tombstone Phase 1 project, and is considered appropriate for this project.

The reseeding rate should be doubled for broadcast application. Preferred seeding method is multiple seed bin rangeland drill with no soil preparation other than simple grading to slope and imprinting and waterbars where applicable. Alternative seeding methods include but are not limited to: • harrow with just enough soil moisture to create a rough surface, broadcast seed and re- harrow, preferably at a 90 degree angle to the first harrow; ·hydro-seeding (most economical in terms of seed cost); and •hand raking and broadcast followed by re-raking at a 90 degree angle to the first raking. These are not the only means of replanting the site. However, these methods have been observed to be effective in similar landscapes. EnCana will provide a Revegetation Security to Garfield County for the amount of $57,250 or $2,500 per acre of disturbance for the Tombstone Phase 3 Pipeline. The security deposit certificate is provided in Attachment 8. (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. A field inspection of the proposed gathering system links and site was conducted by Westwater biologists on August 28, 2007. The survey covered a minimum 50 feet on either side of the center line of the route. The level of infestation of listed noxious weeds is quite low. Other weeds mentioned, e.g. cheatgrass, are a far greater problem and challenge to successful reclamation. The Integrated Vegetation and Noxious Weed management Plan is provided in Attachment 5. (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) is planning to extend its Tombstone Trunk pipeline. This project involves construction, operation, and maintenance of a new trunk pipeline for gathering and transporting of natural gas from related drilling operations in the Orchard Unit area north and south of Interstate I-70. The pipeline and related above-ground facilities will be located in Garfield County, Colorado. The Tombstone Phase 3 pipeline is approximately ±16,641 feet in length and will parallel EnCana's existing 24-inch Parachute to DeBeque pipeline. The proposed route and all construction disturbances will be located within an existing pipeline corridor. The project is located in Sections 5 and 6, Township 8 South, Range 96 West and Sections 32, 33, 28, and 27, Township 7 South, Range 96 West. The pipeline will begin at the E70U lateral in Section 6, Township 8 South, Range 96 West and will end at the existing EnCana pipeline riser located in Section 27, Township 7 South, Range 96 West, just north of the Orchard Compressor Station. Project maps are included in Attachment I. The Tombstone Phase 3 pipeline will gather unprocessed natural gas from various Orchard Unit well pad sites and transport the natural gas to the existing EnCana riser for delivery of the natural gas to the Orchard Compressor Station. The proposed pipeline will consist of approximately 3.2 miles of trunk pipeline. The trunk pipeline will be up to 12-inch diameter for transporting natural gas. EnCana has submitted a Colorado Depaitment of Transportation (CDOT) Utility/Special Use Permit Application requesting permission to construct the 12-inch diameter natural gas pipeline and related above-ground facilities in the CDOT right-of-way in Garfield County, Colorado. The permit application is included in Attachment 2. 1.2 PURPOSE AND NEED EnCana plans to increase production in the Orchard Unit area by up to 50 million standard cubic feet per day (mscfd), each year, for the next several years. The Tombstone Phase 3 pipeline will complete a natural gas gathering system that will utilize existing pipelines to transport the -projected future volumes of natural gas to the Meeker Gas Plant in Rio Blanco County for processing. After processing, 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. 1.3 LOCATION The Tombstone Phase 3 pipeline will begin in Sections 6 and 5, Township 8 South, Range 96 West at milepost 67.7 of Colorado State Highway 6 & 24 and will parallel Highway 6 & 24 and EnCana's existing 24-inch pipeline crossing through Sections 32, 33, 28, and 27 Township 7 South, Range 96 West and connect at EnCana's existing pipeline riser in Section 27, Township 7 South, Range 96 West at milepost 70.5 of State Highway 6 & 24, just north of the Orchard Compressor Station. 1.4 FACILITIES 1.4.1 Project Design The proposed project is approximately 3.2 miles of up to 12-inch diameter, .281 wall X52/60 FBE buried, steel or composite, natural gas. The pipeline will be buried at least 48-inches in depth. The estimated maximum allowable operation pressure (MAOP) is 1,440 pounds per square inch (psi) and the pipeline will be operated at a normal operating pressure of 200 to 500 psi. EnCana will design and construct the pipeline and related facilities in conformance with the requirements of Title 49 CFR, Part 192, "Regulations for the Transportation of Natural Gas and Other Gas by Pipeline: Minimum Federal Safety Standard". 1.5 LAND REQUIREMENTS 1.5.1 Right-of-Way The entire project route is located within an existing, disturbed pipeline corridor that parallels EnCana's existing 24-inch diameter Parachute to DeBeque Pipeline. The pipeline route is within the CDOT right-of-way along Highway 6 & 24 and will be installed entirely within the existing, disturbed area. The proposed Tombstone Phase 3 natural gas pipeline would be installed maintaining an 8-foot off-set from the edge of existing pipeline to the edge of proposed pipeline. The average width of the existing, disturbed pipeline corridor is approximately 75 feet. A temporary work area of 60 feet will be used during construction of this project. The right-of-way will revert to a permanent easement of 30 feet. Construction of the proposed pipeline will disturb approximately 22.9 acres. No new disturbance will occur outside the existing, disturbed area. 1.5.2 Corridor The proposed route will be located within an existing pipeline corridor and the pipelines would parallel EnCana's existing 24-inch pipeline. The pipeline route will parallel CDOT right-of-way along Highway 6 & 24. 1.5.3 Disturbance The Tombstone Phase 3 Pipeline will disturb approximately 22.9 acres in Garfield County. No new disturbance will occur outside the existing disturbance. EnCana has selected a route which will parallel roadways and existing utility corridors for the proposed route; all of the acreage has been previously disturbed from construction activities associated with a previous pipeline, roadways and utility installation. 2 1.5.4 Contractor/Pipe Storage/Offloading Yards EnCana's contractors will haul the pipe used for the project from a pipe wholesale distributor located in Garfield County and no pipe yards will be necessary for the construction of the project. 1.5.5 Aboveground Appurtenances After completion of reclamation activities, above-ground pipeline markers will be installed over the center of the pipeline. 2.0 DEVELOPMENT PLAN REQUIREMENTS 2.1 ATTACHMENTS 2.1.1 Attachments This Development Plan includes the following attachments: Attachment I -Project Maps Attachment 2 -Permits Attachment 3 -Stormwater Attachment 4 -Landowner Information Attachment 5 -Weeds and Wildlife Attachment 6 -Emergency Response Plan Attachment 7 -Spill Plan Attachment 8 -Revegetation Security 2.2 CONSTRUCTION SCHEDULE Construction activities will begin after project approval by the Garfield County Planning Department and approval of the CDOT Utility/Special Use Permit To Construct Application. Construction activities are anticipated to last 12-16 weeks. Construction activities are tentatively scheduled for May 2008 and will continue through August 2008. Working hours will normally range from sunrise to sunset Monday through Saturday. 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. 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 during a construction project. 3 2.3.2.1 Engineering Surveys The construction right-of-way will be marked prior to construction with laths and/or flagging. Laths/flagging will be maintained throughout construction and will not be removed until after reclamation activities have been completed. 2.3.2.2 Clearing, Grading, and Topsoiling Clearing, topsoiling, and grading will be limited to the minimum area required for safe and efficient construction. Available topsoil, up to a depth of six inches, will be segregated from the trenchline only. Where grading is required, topsoil will be stripped from the entire portion of the right-of-way. Topsoil will be removed and stockpiled, and the right-of-way will be graded only to the extent necessary to create safe and efficient pipeline installation conditions. 2.3.2.3 Trenching The ditch will be excavated and sloped in accordance with OSHA specifications. The cover from top of pipe to ground level will be a minimum of 48 inches. Where rock is encountered, tractor- mounted mechanical rippers or rock trenching equipment may be used to facilitate excavation. The bottom of the trench line will remain free of rocks and debris to allow for a solid surface to install the pipe. The trench will be excavated and subsoil material stockpiled at the edge of the workspace. Based on field conditions, gaps will be made in subsoil stockpiles to avoid ponding or excessive diversion of natural runoff during storm events. 2.3.2.4 Pipe Installation Pipe installation will include stringing, bending for horizontal or vertical angles in the alignment, welding the pipe segments together, coating the joint areas to prevent corrosion, and then lowering-in and padding as described in greater detail below. Stringing Pipe will be hauled by truck to the pipeline right-of-way. Each joint of pipe will be unloaded and placed parallel to the ditch. Each section of pipe will be stacked on timber skids to stabilize the pipe until welding is completed. 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. Welding After the pipe joints are bent, the pipe will be lined up end-to-end and clamped into position. The two joints of pipe will be evenly spaced within the clamps to ensure that the pipes are properly aligned, before welding begins. The pipe is then welded in conformance with 49 CFR Part 192, Subpart E. "Welding of Steel Pipelines" and AP! 1104, "Standard for Welding Pipelines and Related Facilities". 4 Welding Inspection Welds will be visually inspected by a qualified inspector. Any defects will be repaired or cut out as required under the specified regulations and standards. Coating To prevent corrosion, the pipe will be externally coated with fusion bonded epoxy coating prior to delivery. After welding, field joints will be coated with fusion bond epoxy coating, tape and primer, or shrink sleeves. Before the pipe is lowered into the ditch, the pipeline coating will be visually inspected and tested with an electronic detector, and any faults or scratches will be repaired. 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. 2.3.2.5 Backfilling Backfilling will begin after a section of the pipe has been successfully placed in the ditch and final inspection has been completed. Backfilling will be conducted using a bulldozer, rotary auger backfill, padding machine or other suitable equipment. Backfilling the trench will use the subsoil previously excavated from the trench. Backfill will be graded and compacted, where necessary, for ground stability, by being tamped or walked in with a wheeled or track vehicle. Compaction will be performed to the extent that there are no voids in the trench. Any excavated materials or materials unfit for backfill will be utilized or properly disposed of in conformance with applicable laws or regulations. Topsoil will not be used to backfill the trench. 2.3.2.6 Cleanup Cleanup activities will be initiated as soon as practicable after backfilling activities have been completed. All construction-related debris will be removed and disposed of at an approved disposal area. The right-of-way will be graded as near as possible to the pre-construction contours and natural runoff and drainage patterns will be restored. The right-of-way will be left in a roughened condition to provide micro-climates for plant development and collection of stormwater runoff. 2.3.3 Road Crossings/Installation The proposed pipeline will not cross any Garfield County roads. The pipeline will be buried at least 48 inches to ensure proper protection of the pipeline. 5 2.3.4 Drainage and Stream Crossings/Installation Cordilleran Compliances Services, Inc. provided consultation with regards to drainage and stream crossings and found that all United States Army Corp of Engineers (USACoE) jurisdictional crossings on the Tombstone Phase 3 route were authorized by Nationwide 404 permit# 12 with no requirement for notification. The route lies within Colorado Highway 6 & 24 right-of-way, and within an existing utility corridor. 2.4 REQUIRED PERMITS The following table lists permits required to construct the project.

(WestWater) has completed the biological assessments of the Tombstone Phase 3 pipeline. The Tombstone Phase 3 pipeline ,..,as surveyed for sensitive 7 >,: resources during the fall of 2007. The Sensitive Resource Reports for the Tombstone Phase 3 pipeline are provided in Attachment 5. Biological surveys were completed and it was determined that no significant impact to wildlife would occur. The trunk line is not specifically located on or across any noted wildlife habitat feature previously identified by CDOW or U.S. Fish and Wildlife Service as noteworthy, essential, or critical to any species known for this habitat in this part of the state. Also completed were surveys for federally listed threatened and endangered plants and BLM sensitive species plants along the project right-of-way. No sensitive plant species were observed along the right-of-way. 2.7.2 Cultural and Paleontological No cultural or paleontological resources were identified during construction of EnCana's existing Parachute to DeBeque pipeline. The Tombstone Phase 3 pipeline will be constructed within an existing disturbance and will not impact any known cultural or paleontological resources. 2.7.3 Wetlands No wetlands were identified during construction of EnCana's existing Parachute to DeBeque pipeline. The Tombstone Phase 3 pipeline will be constructed within an existing disturbance and will not impact any known wetlands. 2.8 REVEGETATION Soil types on the pipeline route support similar species of native vegetation. The following mix is adapted from the seed mix used on the Tombstone Phase 1 project, and is considered appropriate for this project.

The reseeding rate should be doubled for broadcast application. Preferred seeding method is multiple seed bin rangeland drill with no. soil preparation other than simple grading to slope and imprinting and waterbars where applipable:: :··:·.,•.::in : · .. : ·..;.: '''·. · 8 Alternative seeding methods include but are not limited to: • harrow with just enough soil moisture to create a rough surface, broadcast seed and re-harrow, preferably at a 90 degree angle to the first harrow; •hydro-seeding (most economical in terms of seed cost); and • hand raking and broadcast followed by re-raking at a 90 degree angle to the first raking. These are not the only means of replanting the site. However, these methods have been observed to be effective in similar landscapes. EnCana will provide a Revegetation Security to Garfield County for the amount of $57,250 or $2,500 per acre of disturbance for the Tombstone Phase 3 Pipeline. The security deposit certificate is provided in Attachment 8. 2.9 WEED MANAGEMENT PLAN A field inspection of the proposed gathering system links and site was conducted by West Water biologists on August 28, 2007. The survey covered a minimum 50 feet on either side of the center line of the route. The level of infestation of listed noxious weeds is quite low. Other weeds mentioned, e.g. cheatgrass, are a far greater problem and challenge to successful reclamation. The Integrated Vegetation and Noxious Weed management Plan is provided in Attachment 5. Recommended Treatment It is important to know whether the target is annual, biennial, or perennial to select strategies that effectively control and hopefully eliminate the target. Herbicides should not necessarily always be the first treatment of choice when other methods can be effectively employed. Herbicide treatment with two or more herbicide modes of action in fall (after approximately August 15 when natural precipitation is present) is the best method to control difficult species such as Russian knapweed. The resilience and ability to quickly develop immunity to herbicides, particularly those used incorrectly, makes it imperative to use the proper chemicals at the correct time in the specified concentration. Most misuse seems centered around excessive use either in frequency or concentration. This results in mostly top kill and an immune phenotype. Best Management Practices The following practices should be adopted for any construction project to reduce the costs of noxious weed control. The practices include: • top soil, where present, should be segregated from deeper soils and replaced as top soil on the final grade, a process known as live topsoil handling; • wetland vegetation if encountered, should be live handled like sod, temporarily watered if necessary, and placed over excavated sub-soil relative to the position from which the wetland sod was removed; • cut-off collars should be placed on all wetland and stream crossings to prevent back washing or draining of important aquatic resources; • in all cases temporary disturbance should be kept to an absolute minimum; • equipment and materials handling should be done on established sites such as the northern point of origin to reduce area and extent of soil compaction; • disturbances should be immediately replanted with the recommended mix in the re-vegetation 9 section; • topsoil stockpiles should be seeded with non-invasive sterile hybrid grasses if stored longer than one growing season; • prior to delivery to the site, equipment should be cleaned of soils remaining from previous construction sites which may be contaminated with noxious weeds; and • if working in sites with weed-seed contaminated soil, equipment should be cleaned of potentially seed-bearing soils and vegetative debris prior to moving to uncontaminated terrain. on the Tombstone Trunk Phase 3 Pipeline. The Weed Management Plan is provided in Attachment 5. 2.10 EMERGENCY RESPONSE AND SPILL PREVENTION The EnCana Emergency Response Plan is provided in Attachment 6.

EnCana's Spill Plan describes measures to be taken to reduce the risks associated with the use, storage, transportation, production, and disposal of hazardous materials (including hazardous substances and wastes) and petroleum products and outlines the required spill prevention and response (cleanup) procedures for the project. The Spill Plan is provided in Attachment 7. IO 2.11 TRAFFIC IMPACT Colorado State Highway 6 & 24 will be used to access the project. Construction of the pipeline could result in an estimated 40 additional commuter roundtrips per day. Impacts will be temporary and will cease when construction of the pipeline is complete. 2.12 STAGING AREAS/CONSTRUCTION YARDS There are no construction staging areas or yards associated with this project. 2.13 HYDROTEST WATER The natural gas pipeline would be strength tested to prove its integrity and substantiate the MAOP. All pressure tests shall meet DOT standards. Approximately I 00,000 gallons (0.30-acre- feet) of water would be required to hydrostatically test the pipeline. EnCana would use water from its existing Colorado River water rights or from its contract with the West Divide Water Conservancy District. Hydrostatic test discharge water would be discharged into storage tanks and transported via truck for recycling and use in drilling operations. 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 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' 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. 4.0 MITIGATION MEASURES The following protective measures have been adopted by EnCana to address specific resource values and environmental concerns associated with the project. 4.1 NOXIOUS WEEDS All construction equipment and vehicles will be clean and free of soil and weed seed prior to the start of construction. EnCana will monitor the right-of-way for noxious weed infestations and shall control noxious weeds as requested by CDOT representatives and Garfield County Vegetation Management personnel. The Weed Management Plan is provided in Attachment 5. 11 The following measures identify how EnCana will control and reduce the spread of noxious weeds: • Ensure that equipment used on the project is clean and free of noxious weeds before arriving at the project. • 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. The recommended seed mix in Section 2.8 of this plan identifies the appropriate seed mixes for reclamation of disturbed areas. • 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. 4.2 EROSION AND STORMWATER Temporary and permanent erosion control measures will be implemented to control erosion and transport of sediment. Erosion and sediment controls will be used and maintained during all phases of construction, as necessary. Selection of appropriate erosion controls will be selected based on soil properties, steepness of the slope, and anticipated surface flow or runoff. During cleanup, the right-of-way will be graded as near as possible to the pre-construction contours and natural runoff and drainage patterns will be restored. Permanent waterbars will be constructed along all slopes in excess of five percent in gradient. The Stormwater Management Plan included in Attachment 3 provides further mitigation measures to be implemented during construction and operation of the pipeline. 4.3 THREATENED, ENDANGERED, AND SENSITIVE SPECIES Biological surveys were completed for federally listed threatened and endangered plants and BLM sensitive species plants along the proposed pipeline route in September 2007. WestWater biologists have concluded that no suitable habitat exists along the proposed routes for threatened and endangered or sensitive species plants. The Sensitive Resource Report for the Tombstone Trunk Phase 3 is included in Attachment 5. 4.4 CULTURAL RESOURCES The proposed project is located entirely within an existing, disturbed corridor. No known cultural areas are located within this corridor. 4.5 AIR QUALITY Dust shall be controlled by the use of water or an approved dust suppressant, as directed by Garfield County. 12 4.6 SOLID WASTE MANAGEMENT The construction right-of-way will be maintained in a sanitary condition at all times and waste materials on the project will be disposed of promptly at an appropriate waste disposal facility. Waste includes, but is not limited to, human waste, trash, garbage, ashes, welding rods, etc. Portable toilets will be available on-site. Liquid and solid waste generated during construction of the project will be disposed of in an approved manner at an appropriate facility so as not to impact air, water, soil, vegetation, or wildlife. 4. 7 HAZARDOUS MATERIALS MANAGEMENT Construction, operation, and maintenance of the project will require the use of certain potentially hazardous materials such as fuels, explosives, and herbicides. By definition, hazardous materials (substances and wastes) have the potential to pose a significant threat to human health and the environment based upon quantity, concentration, or chemical composition. Generally, hazardous materials will be stored in contractor yards and not on the right-of-way. To prevent the accidental release of hazardous materials and petroleum products, activities shall comply with EnCana's Spill Plan, which is summarized below and provided in Attachment 7 Spill Plan. • Identifies emergency notification and state agency names and phone number that shall be contacted in the event of a spill; • A description of the spill prevention procedures related to vehicle refueling and servicing and the transportation, storage, and disposal of hazardous materials; and • Includes instructions for the collection and disposal of waste, soil, and other materials generated during, and cleanup of a spill. The following precautions shall be taken to ensure that a release of petroleum and hazardous materials is prevented or contained: • Specify containment and cleanup procedures. • Provide necessary materials and labor. • Project area will be inspected frequently to ensure proper use, storage, and disposal of material. • Equipment and vehicles shall be inspected daily for leaks and receive preventative maintenance to reduce the potential for leakage. • Perform all reporting and documentation, as required. 13 ) KEI NATH EnCana Oil & Gas (USA) Inc.

021508.doc ii Revised February 2008 1.0 Introduction This Master Stormwater Management Plan (Master SWMP) satisfies the Colorado Department of Public Health and Environment (CDPHE) Water Quality Control Division (WQCD) General Permit No. COR-030000 issued on May 31, 2007 for Stormwater Discharges Associated with Construction Activities (the Stormwater Construction Permit). EnCana Oil & Gas (USA) Inc. (EnCana) has submitted a General Permit Application to WQCD, a copy of which is provided as Appendix A. This Master SWMP has been prepared in compliance with CDPHE WQCD, the Federal Clean Water Act (CWA), and the National Pollutant Discharge Elimination Permit (NPDES) regulations found in 40 CFR, Part 122.26 for stormwater discharges. The objectives of this Master SWMP are to: 1. Identify all potential sources of pollution which may reasonably be expected to affect the quality of stormwater discharges associated with construction activity within this Master SWMP permit area at each project site; 2. Describe the practices to be used to reduce the pollutants in stormwater discharges associated with construction activity within this Master SWMP permit area at each project site (also known as Best Management Practices (BMPs)); and ensure the practices are selected and described in accordance with good engineering practices, including the installation, implementation and maintenance requirements; 3. Be properly prepared and updated to ensure compliance with the terms and conditions of the Stormwater Construction Permit; 4. Work hand in hand with the Site Specific Records, as described in the following section; and 5. Serve as an education tool and comprehensive reference/guide to stormwater management for inspectors, surveyors, engineers, and EnCana employees and contractors. EnCana construction activities fall under one of two types. Exploration and Production (E&P) sites involve the construction of well pads, roads, and other facilities. Midstream Services (also referred to as Gas Gathering) sites involve the construction of pipelines and compressor, treatment, and other facilities. This Master SWMP is intended to address stormwater management for any and all of these sites within this Master SWMP's Permit Coverage Area. 1.1 Site Specific Records While Volume 1 of the Master SWMP contains all of the general permit area information, Volume 2 of the Master SWMP contains all of the Site Specific Records including all Individual Stormwater Site Plans (Site Plans), as discussed in Section 2.8, and all Inspection and Maintenance Reports (discussed in Section 5.4). These Site Specific Records contain information specific to each site (each well pad, compressor station, section of road/pipeline, etc.), including information on areas of disturbance, ecosystems and vegetation, soil types, percent pre-disturbance vegetation, etc. Any changes to the design of individual sites or the BMPs used at those sites will be noted on the Site Plans as those changes occur, and kept with the Site Specific Records. The Site Specific Records (Volume 2 of the Master SWMP) are bound separately from the body of this Master SWMP; however, both are readily available during any inspection. Both the body of this SWMP (Volume 1) and the Site Specific Records (Volume 2) comprise the entire SWMP, and go hand in hand in keeping EnCana in compliance with stormwater regulations. The Site Specific Records will be kept at the EnCana field office in Parachute during active construction and site inspections to ensure accurate implementation, inspections, and maintenance of BMPs, as well as timely revisions to the Site Specific Records.

SWMP Administrators: • E&P Sites: Terry Gosney, Regional Environmental Coordinator 2717 County Road 215, Suite 100, Parachute, CO 81635 (970) 285-2600 ----···------------· -----------------·---------·--------------------- = ~v1idstream Ser-Jices: Brad Ankrum, Piceance ~v1idstream Operations ~v1anager 2717 County Road 215, Suite 100, Parachute, CO 81635 (970) 285-2600 H:\Data\Stormwater Permits\Orchard Unit SWMP\Orchard Unit SWMP (Tombstone) 021508.doc 1-2 Revised February 2008 2.0 Narrative Description of Master SWMP Permit Coverage Area Name of Permit Coverage Area: Orchard Unit Permit Number: COR-037959 Location of the Permit Coverage Area: • County: Portions of Garfield and Mesa Counties. • City: Located in Colorado approximately 7 miles east of DeBeque and south of the Colorado River within the southern portion of the Piceance Basin. • Township/Section/Range: Township BS, Range 96W, Sections 7-10 and 14-36, Sixth Principal Meridian. Activities at the Permit Coverage Area will likely involve the construction of: • Well pads • Access roads • Pipelines • Compressor stations The above construction activities are only typical and may vary once construction begins. Up-to-date information on the construction of well pads, roads, pipelines, etc. will be kept with the Site Specific Records (Volume 2 of the Master SWMP). 2.1 Sequence of Major Activities Site specific, scheduling, surface use agreements, and/or other constraints can and/or may dictate changes in construction sequences. Significant sequence changes are addressed in the Site Specific Records (Volume 2 of the Master SWMP). Specific details on the construction and maintenance of BMPs mentioned below are provided in the Stormwater Manual of Best Management Practices (BMP Manual) as discussed in Section 3.3. 2.1.1 Well Pads and Roads Construction activities for well pads and roads are generally completed in the following sequence: Preconstruction: 1. Surveys. Topographic, vegetation, wildlife and archeology, as dictated. 2. Temporary BMP's. Where physical access is available, installation of terminal perimeter and temporary sediment controls, such as wattles, silt fence and/or other as necessary. Actual BMPs used for each site are shown on the Site Plans (discussed in Section 2.8) and kept with the Site Specific Records (Volume 2 of the Master SWMP). Construction: 3. Vegetation Clearing. Vegetation will be cleared/grubbed and placed along the perimeter at the terminal discharge edges/points in a windrow and/or dam beyond the edge of excavation and at any run-on-protection discharge points, and/or chipped or other depending on landowner requirements. H:\Data\Stormwater Permils\Orchard Unit SWMP\Orchard Unit SWMP (Tombstone) 021508.doc 2-1 Revised February 2008 4. Diversions and Retention Reservoirs. After vegetation clearing and prior to topsoil stockpiling, diversions are to be placed for run-on-protection (ROP) to prevent the greater landscape from discharging onto the planned disturbance. Temporary sediment control BMPs shall be placed at the discharge points of the ROP until permanent erosion controls can be installed along the entire length of the ROP. Diversions are to be installed along the terminal discharge edge inside of the vegetation windrows to convey site water/sediment to terminal discharge points where rough retention reservoirs are to be installed. The retention reservoir outlets are to receive temporary sediment control BMPs until permanent retention reservoirs and erosion, drainage, and sediment BMPs can be installed. 5. Topsoil Stripping/Conservation. All ACCESSIBLE TOPSOIL is to be removed from areas that are to be excavated, covered in subsoils, or turned into stabilized unpaved surfaces. If initial topsoil stockpileareas·are insufficient to-accommodate the·quantities-oftopsoil· being-gemirated;-the excess-- is to be placed at either end of the subsoil stockpile and segregated as much as possible. After major earthwork, grading, and eroslon/drainage/sedlrnent controis are complete, any areas that can be identified for immediate interim reclamation shall receive topsoil. 6. General Rough Grading. The site location will be graded to provide suitable surfaces for vehicle traffic and/or building sites, and may be graded to establish surface drainage patterns, such as berms or roadside ditches as necessary. 7. Facility Specific Grading. Individual facilities may require additional excavation to allow for construction of foundations. Excess soil will typically be used in general site grading. 8. Foundation Construction. To support facilities (such as tanks, processing equipment, etc), foundations will be constructed. Foundations may consist of select backfill, concrete spread footings, or piles. Finished support elevations are to be installed twelve to eighteen inches (12-18") above finished grade or the lowest point of the facility. 9. Facility Construction. Tanks, processing equipment, etc. will be constructed. Interim Reclamation: 10. Gravel Surfacing. Areas used for access, parking, or materials staging will typically be gravel surfaced. 11. Reclamation of Unused Areas. Areas not needed for facilities, roads, parking, or materials staging will generally be reclaimed. Salvaged topsoil will be spread and the vegetative seed mix will be applied. 12. Application of Erosion Stabilization. Depending on terrain (e.g. steep slopes and drainage crossings) additional measures may be applied to increase stability of the reclaimed area. Final Reclamation: 13. Reclamation of Post-Operation Areas. When operation of well pad or road is no longer necessary, the area will be decommissioned and all newly disturbed areas will be reclaimed. Any remaining topsoil will be spread and the vegetative seed mix will be applied. This may occur after termination of this permit and under the coverage of a new construction permit. 2.1.2 Pipelines Construction activities for pipelines are generally completed in the following sequence: Preconstruction: 1. Surveys. Topographic, vegetation, wildlife and archeology, as dictated. 2. Mark Right-Of-Way. The construction right-of-way (ROW) will be marked prior to construction with laths and/or flagging. Laths/flagging will be maintained throughout construction and will not be removed until after reclamation activities have been completed. H:\Data\Stormwater Permits\Orchard Unit SWMP\Orchard Unit SWMP (Tombstone) 021508.doc 2-2 Revised February 2008 3. Temporary BMPs. EnCana's stormwater inspectors will determine locations to install preconstruction temporary erosion control devices, per site specific BMP installation plans and as necessary. EnCana's contractor will maintain the erosion control structures as directed by the stormwater inspectors throughout all phases of construction, or until permanent erosion control measures are installed. Actual BMPs used for each site are shown on the Site Plans, which are kept with the Site Specific Records (Volume 2 of the Master SWMP). Construction: 4. Vegetation Clearing. If necessary, vegetation will be cleared and placed in a windrow at the edge of the work area to be used later in reclamation activities, removed from the construction site, or burned/chipped depending on landowner requirements. Details for windrows are provided within the Stockpiling BMP of the BMP Manual (discussed in Section 3.3). 5. Topsoil Stripping. All ACCESSIBLE TOPSOIL (from the entire width of the right-of-way) will be removed and temporarily stockpiled along the up-hill side of the right-of-way (if terrain grades will allow) for later use in reclamation activities. 6. General Grading. For pipeline segments that occur in relatively rough terrain, general grading will be conducted to create a safe and workable ground surface. This is generally done to form a relatively level work surface on steep cross slopes and to reduce slopes in undulating terrain (arroyo and wash crossings). The site location will be graded to provide suitable surfaces for vehicle traffic and/or building sites, and may be graded to establish surface drainage patterns, such as berms or roadside ditches as necessary. 7. Trench Excavation. The trench needed for pipeline installation is almost always off-set in the ROW. The surveyors may indicate the location of the trench on their pipeline lateral. Generally, the trench will be located in the first third of the ROW. The remaining two thirds of the ROW will be used for working space. The trench depth and width will vary with the number of pipes to be installed and the pipe diameter. Generally, a 4-foot deep trench will be excavated by track-mounted excavators. The ditch will be excavated and sloped in accordance with OSHA specifications. The cover from top of pipe to ground level will be a minimum of 36 inches. Where rock is encountered, tractor-mounted mechanical rippers or rock trenching equipment may be used to facilitate excavation. The trench will be excavated and subsoil material stockpiled within the confines of the approved right-of-way limits. Trench spoil will be stored in a separate location from the previously segregated topsoil. 8. Pipe Installation. Pipe installation will include stringing, bending for horizontal or vertical angles in the alignment, welding the pipe segments together, coating the joint areas to prevent corrosion, and then lowering-in and padding. 9. Stringing. Pipe will be hauled by truck to the pipeline ROW. Each joint of pipe will be unloaded and placed parallel to the ditch. 10. Bending. After the joints of pipe are strung along the ditch, individual joints of pipe may need to be bent to accommodate horizontal and vertical changes in direction. Field bends will be made utilizing a hydraulically operated bending machine. Where the deflection of a bend exceeds the allowable limits for a field-bent pipe, factory (induction) bends will be installed. 11. Welding. After the pipe joints are bent, the pipe is lined up end-to-end and clamped into position. The pipe is then welded in conformance with 49 CFR Part 192, Subpart E. "Welding of Steel Pipelines" and API 1104, "Standard for Welding Pipelines and Related Facilities". 12. Welding Inspection. Welds will be visually inspected by a qualified inspector. Any defects will be repaired or cut out as required under the specified regulations and standards. 13. Coating. To prevent corrosion, the pipe will be externally coated with fusion bonded epoxy coating prior to delivery. After welding, field joints will be coated with fusion bond epoxy coating, tape and primer, or shrink sleeves. Before the pipe is lowered into the ditch, the pipeline coating will be visually inspected and tested with an electronic detector, and any faults or scratches will be repaired. 14. Lowering-In and Padding. Once the pipe coating operation has been completed, a section of the pipe will be lowered into the ditch. Side-boom tractors may be used to simultaneously lift the pipe, position it over the ditch, and lower it in place. Inspection will be conducted to verify: that minimum H:\Data\Stonnwater Permits\Orchard Unit SWMP\Orchard 2-3 Revised February 2008 Unit SWMP (Tombstone) 021508.doc cover is provided; the trench bottom is free of rocks, debris, etc.; external pipe coating is not damaged; and the pipe is properly fitted and installed into the ditch. Specialized padding machines will be used to sift soil fines from the excavated subsoil to provide rock-free pipeline padding and bedding. In rocky areas, padding material or a rock shield will be used to protect the pipe. Topsoil will not be used to pad the pipe. At the completion of lowering-in and padding activities the contractor may install trench breakers around the pipelines to minimize subsurface water flow. Details for trench breakers are provided within the BMP Manual (discussed in Section 3.3). 15. Backfilling. Backfilling will begin after a section of the pipe has been successfully placed in the ditch and final inspection has been completed. Backfilling will be conducted using a bulldozer, rotary auger backfill, padding machine or other suitable equipment. Backfilling the trench will use the subsoil previously excavated from the trench. Backfill will be graded and compacted, where necessary for ground-stability;-by·beingiampectorwalkectirrwith-a-wheetectortrackvehicle~Compactiorrwill-be performed to the extent that there are no voids in the trench. Any excavated materials or materials unfit for backfill will be utilized or properly disposed of in conforrnance wiih applicable laws or regulations. 16. General Grading. If general grading was conducted to facilitate pipeline construction, these materials will be replaced and graded to recreate the preconstruction topography. Final Reclamation: 17. Cleanup. Cleanup activities will be initiated as soon as practicable after backfilling activities have been completed. All construction-related debris will be removed and disposed of at an approved disposal facility. 18. Subsoil and Topsoil Placement. Subsoil will be evenly re-contoured across the right-of-way to pre-construction conditions. After the subsoil has been re-spread the contractor will spread the previously segregated topsoil back across the right-of-way. The topsoil will be evenly spread to original contours. 19. Vegetation. After any remaining topsoil is spread, the vegetative seed mix will be applied. The area will be revegetated according to private landowner Surface Use Agreements and/or according to the SLM/Forest Service reclamation requirements. Details for revegetation are provided within the BMP Manual (discussed in Section 3.3) and the Revegetation Manual (provided as Appendix 8). 20. Application of Erosion Stabilization. Depending on terrain (e.g. steep slopes and drainage crossings) additional measures may be applied to increase stability of the reclaimed area. Possible erosion stabilization methods are provided within the BMP Manual (discussed in Section 3.3). Actual locations and measures used are shown on the Site Plans, which are kept with the Site Specific Records (Volume 2 of the Master SWMP). 2.1.3 Compressor Stations, Treatment Facilities, or Other Facilities. Construction activities for compressor stations, treatment facilities, and other facilities are generally completed in the following sequence: Preconstruction: 1. Surveys. Topographic, vegetation, wildlife and archeology, as dictated. 2. Temporary BMP's. Where physical access is available, installation of terminal perimeter and temporary sediment controls, such as wattles, silt fence and/or other as necessary. Actual BMPs used for each site are shown on the Site Plans, which are kept with the Site Specific Records (Volume 2 of the Master SWMP). H:\Data\Stormwater Permits\Orchard Unit SWMP\Orchard Unit SWMP (Tombstone) 021508.doc 2-4 Revised February 2008 Construction: 3. Vegetation Clearing. Vegetation will be cleared/grubbed and placed along the perimeter at the terminal discharge edges/points in a windrow and/or dam beyond the edge of excavation and at any run-on-protection discharge points, and/or chipped or other depending on landowner requirements. 4. Diversions and Retention Reservoirs. After vegetation clearing and prior to topsoil stockpiling, diversion are to be placed for ROP to prevent the greater landscape from discharging onto the planned disturbance. Temporary sediment control BMP's shall be placed at the discharge points of the ROP until permanent erosion controls can be installed along the entire length of the ROP. Diversions are to be installed along the terminal discharge edge inside of the vegetation windrows to convey site water/sediment to terminal discharge points where rough retention reservoirs are to be installed. The retention reservoir outlets are to receive temporary sediment control BM P's until permanent retention reservoirs and erosion, drainage, and sediment BMP's can be installed. 5. Topsoil Stripping/Conservation. All ACCESSIBLE TOPSOIL is to be removed from areas that are to be excavated, covered in subsoils, or turned into stabilized unpaved surfaces. If initial topsoil stockpile areas are insufficient to accommodate the quantities of topsoil being generated, the excess is to be placed at either end of the subsoil stockpile and segregated as much as possible. After major earthwork, grading, and erosion/drainage/sediment controls are complete, any areas that can be identified for immediate interim reclamation shall receive topsoil. 6. General Rough Grading. The site location will be graded to provide suitable surfaces for building sites and vehicle traffic, and may be graded to establish surface drainage patterns, such as berms or roadside ditches as necessary. 7. Excavation. Soil will be excavated to allow for the construction of foundations. Trenches will be excavated for all underground piping and conduit. Excess soil will typically be used in general site grading. 8. Foundation Construction. Foundations will be constructed to support facility buildings. Foundations may consist of select backfill, concrete spread footings, piles, etc. Finished support elevations are to be installed twelve to eighteen inches (12-18") above finished grade or the lowest point of the facility. 9. Facility Construction. Buildings, tanks, processing equipment, etc. will be constructed. Utilities will be installed. Interim Reclamation: 10. Landscaping. If necessary, certain areas will be spread with topsoil and landscaped. 11. Gravel Surfacing. Areas used for access, parking, or materials staging will typically be gravel surfaced. 12. Reclamation of Unused Areas. Areas not needed for facilities, roads, parking, or materials staging will generally be reclaimed. Salvaged topsoil will be spread and the vegetative seed mix will be applied. 13. Application of Erosion Stabilization. Depending on terrain (e.g. steep slopes and drainage crossings) additional measures may be applied to increase stability of the reclaimed area. Possible erosion stabilization methods are provided within the BMP Manual (discussed in Section 3.3). Actual locations and measures used are shown on the Site Plans, which are kept with the Site Specific Records (Volume 2 of the Master SWMP). Final Reclamation: 14. Reclamation of Closed Facilities. When facilities are no longer necessary, the buildings may be demolished, according to approved procedures. All construction materials will be removed and the newly disturbed areas will be reclaimed. Any remaining topsoil will be spread and the vegetative seed mix will be applied. This may occur after termination of this permit and under the coverage of a new construction permit. H:\Data\Storrnwater Permits\Orchard Unit SWMP\Orchard Unit SWMP (Tombstone) 021508.doc 2-5 Revised February 2008 2.2 Area Estimates The Permit Coverage Area encompasses portions or all of 51 sections of surface land (approximately 32,600 acres) in Township 8 and 9 South, Range 96 and 97 West. Development of the natural gas resource and related facilities within the area is estimated to result in a total disturbance area of 999+ acres. Because the area will vary over time, these are only approximate estimates. This information is used to help determine the extent of control measures (BMPs) needed. 2.3 Description of Existing Topography and Soils The Permit Coverage Area consists of relatively flat mesas and ridge crests, mountainsides and steep ___ c:<:ioyon~_with areas of rock outcrop, and valle)I ~o!toms. . ___ __ . ·-___________ _ Elevations within the Permit Coverage Area range from approximately 5,000 feet above mean sea level (amsl) along the Colorado River lo 6,400 feet near the southeast corner of the area. Annual precipitation within the Permit Coverage Area ranges from 25 to 40 inches. Soils surrounding the Permit Coverage Area are distributed according to the major soil forming factors including climate (effective moisture and temperature), parent material, topographic position, and slope. The soils table within Appendix C provides a summary of the soil types found within the Permit Coverage Area (including permeability, available water capacity, surface runoff, erosion hazard, and others). Most of these soil types are considered to possess moderate to very severe potential for water erosion. 2.4 Description of Existing Vegetation The existing percent vegetative ground cover for each well pad, section of roadway/pipeline, etc. within the Permit Coverage Area is estimated on each inspection and maintenance report form {discussed in Section 5.4), which are kept with the Site Specific Records (Volume 2 of the Master SWMP). The majority of the Orchard Unit consists of pinyon-juniper woodlands. However, there is also a large area of big sagebrush and a smaller area of greasewood fans/flats. The vegetation within the Orchard Unit consists of woodland hillsides dominated by Utah Juniper (Juniperus osteosperma), with a few scattered pinyon pine (Pinus edulis) at higher elevations or north-facing slopes. Drainages and ridge tops/mesas in the Unit (Samson Mesa, Creek Mesa) were dominated by Basin and Wyoming big sagebrush (Artemisia spp. ), greasewood ( Sarcobatus vermiculatus) and shadscale (Atriplex confertifolia). Drainages in the southeast portion of the project area, as well as high-elevation hillsides, had dense groves of scrub oak (Quercus gambeli1) with understory species such as creeping hollygrape (Mahonia repens), mountain pussytoes (Antennaria parvifo/ia), yarrow (Ache/lea mi//efo/ium), northern sweetvelch (Hedysarum boreale), and sego lily (Ca/ochortus nutta/11). Some patches of serviceberry (Amelanchier a/nifolia) and mountain-mahogany (Cercocarpus montanus) were also found along drainage hillsides. The most common understory species found within the sagebrush/greasewood flats included orange globemallow (Sphaeralcea munroana), yellow and red prickly pear cactus (Opuntia polyacantha), cryptantha (Cryptantha glomerata), and yucca (Yucca glauca). The entire Orchard Unit has, to some extent, been affected by cheatgrass (downy brome) (Bromus tectorum) (see Invasive, Non-Native Species). It is often associated with sagebrush communities and disturbed areas, especially two-track roads. In the pinyon/juniper woodlands, this species may be found as the understory. Stressed by the recent drought, many pinyon pine trees in the Colorado Plateau have succumbed to an engraver beetle (lps confusus) infestation. However, in the Orchard Unit, the scattered pinyon pine trees have shown few signs of infestation. 2.5 Identification of Potential Pollution Sources Potential sources of pollution are associated with all phases of the project from the start of construction though interim reclamation and up until final stabilization has occurred. Final stabilization occurs when construction activities have been completed and all disturbed areas have been either built on, paved, or a uniform H:\Data\Stormwater Permils\Orchard Unit SWMP\Orchard Unit SWMP (Tombstone) 021508.doc 2-6 Revised February 2008 vegetative cover has been established with a density of at least 70 percent of pre-disturbance levels, or equivalent permanent, physical erosion reduction methods have been employed. The most common source of pollution during construction is sediment resulting from the erosion of recently cleared and/or graded areas, such as cuUfill slopes and soil stockpiles. However, there may be many potential pollution sources at any given site. The following types of conditions that might affect the potential for a pollutant source to contribute pollutants to stormwater (CDPHE, 20078) shall be evaluated: • The frequency of the activity (i.e., does it occur every day or just once a month? can it be scheduled to occur only during dry weather?); • Characteristics of the area where the activity takes place (i.e., surface type (pavement, gravel, vegetation, etc.), physical characteristics [site gradients, slope lengths, etc.]); • Ability of primary and secondary containment (fuel tanks, drum storage, etc.) at product storage and loading/unloading facilities to prevent and contain spills and leaks; • Proximity of product storage and loading/unloading facilities to waterways or drainage facilities; • Concentration and toxicity of materials which may to be found in the site's stormwater runoff; and • Contamination of storage facilities/containment with stored materials (i.e., used oil drums or tanks coated with spilled oil). The following items are potential sources of pollutants at the Orchard Unit. Each of the potential sources of pollutants will be controlled using one or more of the following types of BMPs: Erosion Controls, Drainage Controls, Sediment Controls or Non-Stormwater Controls. Descriptions and details for each of these types of BMPs are provided in the BMP Manual (discussed in Section 3.3). Actual BMPs used at each site are shown on the Site Plans (discussed in Section 5.4). Construction: • All Disturbed and Stored Soils: Erosion Controls, Drainage Controls, Sediment Controls. • Vehicle Tracking of Sediments: Sediment Controls, Non-Stormwater Controls. • Management of Contaminated Soils: Non-Stormwater Controls. • Loading and Unloading Operations: Non-Stormwater Controls. • Outdoor Storage Activities (Building Materials, Fertilizers, Chemicals, etc.): Non-Stormwater Controls. • Vehicle and Equipment Maintenance and Fueling: Non-Stormwater Controls. • Significant Dust or Particulate Generating Processes: Non-Stormwater Controls. • Routine Maintenance Activities Involving Fertilizers, Pesticides, Detergents, Fuels, Solvents, Oils, etc.: Non-Stormwater Controls. • On-Site Waste Management Practices (Waste Piles, Liquid Wastes, Dumpsters, etc.): Non-Stormwater Controls. • Concrete Truck/Equipment Washing, Including the Concrete Truck Chute and Associated Fixtures and Equipment: Non-Stormwater Controls. • Dedicated Asphalt and Concrete Batch Plants: There will be no asphalt or concrete batch plants located within the Permit Coverage Area of this SWMP. • Non-Industrial Waste Sources Such as Worker Trash and Portable Toilets: Non-Stormwater Controls. Interim/Final Reclamation: • All Disturbed and Stored Soils: Erosion Controls, Drainage Controls, Sediment Controls. • Vehicle Tracking of Sediments: Sediment Controls, Non-Stormwater Controls. H:\Oata\Stormwater Permits\Orchard Unit SWMP\Orchard Unit SWMP (Tombstone) 021508.doc 2-7 Revised February 2008 • Vehicle and Equipment Maintenance and Fueling: Non-Stormwater Controls. • Significant Dust or Particulate Generating Processes: Non-Stormwater Controls. • Non-Industrial Waste Sources such as Worker Trash and Portable Toilets: Non-Stormwater Controls. 2.6 Allowable Sources of Non-Stormwater Discharge Allowable sources of non-stormwater discharge within the Permit Coverage Area include the following: • Uncontaminated Springs. Although there are several springs within the Permit Coverage Areas, none of these springs are currently located in areas where soil disturbance will occur. If this changes int~~future~th_e_contr:ols used at any such locatioll ;yillbe_noted Witll_ltl~~ite_Specific~_EJ~ords ......... __ _ • Landscape Irrigation Return Flow. There are several locations where pipelines cross through irrigated fields. These locations will be treated similarly to any water crossing with the use of an appropriate control which will be noted in the Site Specific Records. • Construction Dewatering. Construction dewatering is described and discussed in Section 3.2.5. • Concrete Washout. Concrete washout is described and discussed in Section 3.2.4. • Emergency Fire Fighting Water. Water used to put out any type of fire is considered an allowable source of non-stormwater discharge. No other non-stormwater discharges are allowed under the Stormwater Construction Permit. Other types of non-stormwaier discharges must be addressed in a separate permit issued for ihat discharge. 2.7 Receiving Water Runoff from disturbed areas during construction will be controlled and/or routed through the use of one or more BMPs, as described later in this plan, prior to being discharged to receiving waters. However, it may be expected that runoff from certain areas will infiltrate into the earth and is not expected to contribute to receiving waters. Runoff from the Permit Coverage Area will flow to the Colorado River directly or through one of the following tributaries: Horsethief Creek, Moffat Gulch, Smith Gulch, Alkali Creek, Little Alkali Creek, Wallace Creek, Spring Creek, or other unnamed tributaries. Intermittent drainages occur along Smith Gulch, and Alkali and Little Alkali Creeks. All other drainages are ephemeral. No wetland habitats have been documented along any drainages. However, floodplains occur along Alkali and Little Alkali Creeks. 2.8 Master SWMP Permit Area Map and Individual Stormwater Site Plans An overall Master SWMP Permit Area Map is provided as Appendix D. This map is likely to change constantly and will be updated at least annually. The Master SWMP Permit Area Map includes: • Contours and elevations (topography) with existing drainage patterns; • Locations and names of major surface waters such as streams, wetlands, irrigation ditches, canals, etc .... ; • Master SWMP permit area boundaries; and • Construction area locations including roads, pipelines, well pads, compressor station facilities, treatment facilities, water parks, and all other facilities. Individual Stormwater Site Plans (Site Plans) of each site (well pad, access road, section of pipeline, etc.) are provided with the Site Specific Records (Volume 2 of the Master SWMP) Separate Site Plans will be H:\Data\Stormwater Permits\Orchard Unit SWMP\Orchard Unit SWMP (Tombstone) 021508.doc 2-8 Revised February 2008 developed for each phase of construction: preconstruction, construction, interim reclamation (if applicable), final stabilization (if applicable) and final reclamation (if applicable). These Site Plans include: • Construction site boundaries (this is the area expected to be disturbed by clearing, excavating, grading, or other construction activities); • Contours and elevations (topography) with existing and proposed drainage patterns; • Limits of well pads and locations of reserve pits and well heads (if applicable); • All areas of ground surface disturbance, including areas of cut and fill; • Locations of all potential pollutant sources listed in Section 2.5 (including areas used for vehicle fueling, the storage of materials, equipment, soil, or waste, etc ... ); • Locations of all minor surface waters and all anticipated allowable sources of non-stormwater discharge (including springs, dewatering, concrete washout, etc ... ); • Locations of all existing and planned BMPs (including erosion, drainage, and sediment controls); • Locations, names, and distances to streams, wetlands, irrigation ditches, canals, and other surface waters; and • The size, type and location of any outfall(s). If the stormwater discharge is to a municipal separate stormwater system, name that system, the location of the storm sewer discharge, and the ultimate receiving water(s). Figures showing typical BMP locations along roadways and pipelines are provided as part of the BMP Manual (discussed in Section 3.3). H:\Oata\Stormwater Permits\Orchard Unit SWMP\Orchard Unit SWMP (Tombstone) 021508.doc 2-9 Revised February 2008 3.0 Best Management Practices (BMPs) A key component of this Master SWMP is employing BMPs to improve stormwater quality. Local factors will be evaluated to determine what BMPs are suitable and practical at different locations. BMPs will be employed in different combinations during construction activities and phases as conditions warrant. Due to the fact that this Master SWMP is likely to cover more than one ecosystem (as described in Section 2.4), the selection of BMPs (including type, quantity, sequence/combination, etc.) will vary at each site within the Master SWMP Permit Area. Specific BMPs to be employed at each well pad, road, pipeline, or other facility are identified on the Site Plans, which are kept with the Site Specific Records (Volume 2 of the Master SWMP). ----------~------------------------- 3.1 Erosion, Drainage, and Sediment Control BMPs The primary method for controlling erosion, drainage, and sediment transport consists of minimizing initial disturbance of the soil and ground cover. However, many other methods can also be used. All stormwater- related BMPs will fall under at least one of the following three types of controls: • Erosion Control. Any source control practice that protects the soil surface and/or strengthens the subsurface in order to prevent soil particles from being detached by rain or wind, thus controlling raindrop, sheet, and/or rill erosion. • Runoff Control. Any practice that reduces or eliminates gully, channel, and stream erosion by minimizing, diverting, or conveying runoff. • Sediment Control. Any practice that traps the soil particles after they have been detached and moved by wind or water. Sediment control measures are usually passive systems that rely on filtering or settling the particles out of the water or wind that is transporting them prior to leaving the site boundary. BMPs may also be classified as either structural or non-structural controls: • Structural Control. Handles sediment-laden stormwater prior to it leaving each site. Structural BMPs are used to delay, capture, store, treat, or infiltrate stormwater runoff. Some examples of structural BMPs include sediment traps, diversions, and silt fences. Most Runoff Controls and Sediment Controls can also be classified as Structural Controls. • Non-structural Control. Reduces the generation and accumulation of pollutants, including sediment, from a construction site by stabilizing disturbed areas and preventing the occurrence of erosion. Some examples of non-structural BMPs include revegetation, mulching, and surface roughening. These types of stabilization techniques are not only the most effective method for reducing soil loss, but they are also normally the most cost effective due to low initial cost and reduced maintenance requirements. Most, but not all, Erosion Controls can also be classified as Non-structural Controls. The Site Plans, as mentioned previously and kept with the Site Specific Records (Volume 2 of the Master SWMP), show the proposed locations of all erosion, drainage, and sediment control BMPs (both structural and non-structural). Detailed descriptions, design criteria, construction specifications, and maintenance information for all BMPs are provided in the BMP Manual (discussed in Section 3.3). 3.2 Non-Stormwater Control BMPs Non-stormwater controls include general site and materials management measures that indirectly aid in the minimization of water pollution. Types of pollution sources include, but are not limited to, litter, oil and grease, hazardous material spills, and sediment. H:\Dala\Stormwater Permits\Orchard Unit SWMP\Orchard Unit SWMP (Tombstone) 021508.doc 3-1 Revised February 2008 3.2.1 Materials Delivery and Storage The good housekeeping practices listed below will be followed on site during construction and operation: • An effort will be made to store only enough product required for task completion. • All materials stored on site will be stored in a neat and orderly manner in appropriate containers and, where possible, under a roof or other enclosure, and/or within secondary containment areas to avoid contact with stormwater. • Products will be kept in their original containers with the original manufacturer's label. • Substances will not be mixed with one another unless recommended by the manufacturer. • Whenever possible, all of the product will be used before disposing of the container. • Manufacturer's recommendations for proper use and disposal will be followed. Additional information on material delivery and storage is available in the BMP Manual (discussed in Section 3.3). 3.2.2 Material Handling and Spill Prevention In addition to the material storage practices (listed in the previous section) that will be used to reduce the risk of spills or other accidental exposure of materials and substance, the BMP Manual (discussed in Section 3.3) will provide more detailed information on spill prevention and control. Furthermore, the Spill Prevention, Control and Countermeasure (SPCC) Plan will be followed for the control of hydrocarbons. In general, spill prevention and response procedures will include notification (CDPHE 24-hour spill reporting line -877-518- 5608), clean-up with the use of spill kits and absorbents, and ensuring that materials and wash water can not discharge from the site, and never into a storm drain system or stream. 3.2.3 Vehicle Cleaning, Fueling, Maintenance, and Tracking Controls As required by EnCana Oil & Gas (USA), Inc. master service agreement(s) and drilling contract(s), contracting companies and/or vendors are required to service all vehicles and equipment prior to entering EnCana facilities. However, in the event maintenance procedures are required at EnCana facilities, all fluids transferred must utilize secondary containment and drip pans to minimize a release of materials and properly dispose or recycle spent materials in compliance with local, state, and federal guidelines. While on site, equipment will be parked, serviced, and fueled within designated areas. Equipment fueling on pipeline rights-of-way will be completed where necessary during active construction. Periodic inspections of equipment and control procedures will be implemented. Selected equipment may be fueled in place using fuel trucks. When necessary, equipment and machinery will be decontaminated at an on-site decontamination area prior to removal from the construction area. Areas will be provided with adequate waste disposal receptacles for liquid as well as solid waste. Vehicle tracking of sediments is not expected to be a problem due to construction scheduling. Construction vehicles will remain on site throughout earth-moving activities. All other vehicles remain in stabilized areas and do not enter the construction area until that area is stabilized. However, applicable BMPs (such as scheduling (to minimize site access), stabilized construction entrances, vehicle cleaning, etc.) will be utilized if sediment tracking does become a problem. In addition to the typical practices listed above, the BMP Manual (discussed in Section 3.3) provides more detailed information on vehicle cleaning, fueling, maintenance, and tracking controls. 3.2.4 Waste Management and Disposal As required by EnCana Oil & Gas (USA), Inc. master service agreement(s) and drilling contract(s), contracting companies and/or vendors are required to manage all waste generated by their activities at EnCana facilities in H:\Data\Stormwater Perrnits\Orchard Unit SWMP\Orchard 3-2 Revised February 2008 Unit SWMP (Tombstone) 021508.doc compliance with local, state, and federal guidelines. EnCana Oil & Gas (USA) utilizes a periodic inspection program to ensure waste management requirements are fulfilled and inspections are documented. A few of the waste management procedures that will be followed include the following: • Proper bins will be provided for trash collection and disposal in compliance with local, state, and federal guidelines. • Contaminated soils will be placed into a lined and bermed area. Samples of the impacted soil will be collected and a complete characterization analysis will be performed. When applicable, the impacted soil will be sent to a licensed disposal facility. • ne contractorwill proviC!eportaorinoilets. ··Sanitary-waste will beregTHarly to1iecteernya licensed sanitary waste management contractor and disposed of in an approved manner. • In the event that sediment is inadvertently transported off the construction site, it will be collected and returned to the site and placed on the soil stockpile or spread over the construction pad area and compacted. On well pads and access roads concrete washout is used as an interior conductor pipe ballast. Concrete washout water can NOT be discharged to surface waters or to storm sewer systems without separate permit coverage. However, discharge to the ground of concrete washout water from washing of tools and concrete mixer chutes may be authorized by this permit, provided that (CDPHE, 2007a): 1. The source is identified in the SWMP; 2. BMPs are included in the SWMP to prevent pollution of groundwater; and 3. These discharges do not leave the site as surface runoff or to surface waters. Locations where concrete washout activities take place are shown on the Site Plans. Additional waste management procedures, including solid waste, hazardous waste, contaminated soil, concrete washout, and septic and sanitary waste, are included in the BMP Manual (discussed in Section 3.3). 3.2.5 Dewatering Dewatering refers to the mechanical removal of water from an excavation or other structure. Both groundwater and stormwater may require dewatering during construction. Dewatering of pipelines at the completion of hydrostatic testing will be required for most pipeline installations. 3.2.5.1 Groundwater Dewatering Groundwater is very rarely encountered during the construction activities associated with either E&P sites or Midstream Services sites. If groundwater is encountered, it is typically during construction of a pipeline across a stream crossing. These pipelines are either bored under the stream or a flume is utilized. Non-stormwater construction dewatering of groundwater can NOT be discharged to surface waters or to storm sewer systems without separate permit coverage. However, discharges to the ground of water from construction dewatering activities may be authorized by this permit, provided that (CDPHE, 2007a): 1. The source is groundwater and/or groundwater combined with stormwater that does not contain pollutants in concentrations exceeding the State groundwater standards in Regulations 5 CCR 1002-41 and 42; 2. The source is identified in the SWMP; 3. BMPs are included in the SWMP; and 4. These discharges do not leave the site as surface runoff or to surface waters. H:\Data\Stormwater Permits\Orchard Unit SWMP\Orchard 3-3 Revised February 2008 Unit SWMP (Tombstone) 021508.doc Dewatered groundwater shall be pumped or diverted to a sediment control BMP prior to discharge to the ground. Locations of groundwater dewatering, as well as any BMPs utilized, will be noted on the Site Plans as soon as such dewatering occurs. Additional information on groundwater dewatering is provided in the BMP Manual, discussed in Section 3.3. 3.2.5.2 Stormwater Dewatering The discharge of pumped stormwater (not including groundwater or other non-stormwater sources) from excavations, ponds, depressions, etc., to surface water, or to a municipal separate storm-sewer system is allowed by the Stormwater Construction Permit, as long as the dewatering activity and associated BMPs are identified in the SWMP (including location of the activity}, and BMPs are implemented in accordance with the BMP Manual, discussed in Section 3.3 (CDPHE, 2007c). Stormwater that collects in open depressions or trenches during construction activities will be dewatered into an existing sediment control, such as a detention pond, a sediment trap, or simply into a well-vegetated area to percolate into the ground and catch suspended sediment. The quality, source, and location of dewatering, as well as any BMPs utilized, will be noted on the Site Plans as soon as such dewatering occurs. Additional information on stormwater dewatering is provided in the BMP Manual, discussed in Section 3.3. 3.2.5.3 Pipeline Dewatering New Department of Transportation (DOT) pipelines are hydrostatically tested with water upon completion of construction. Once the hydrostatic testing has been completed, dewatering of the pipeline must occur. This will involve the insertion of a displacer, commonly referred to as a pig, in the pipeline. The discharge rate will be regulated, and energy dissipation devices, and/or sediment controls will be used, as necessary, to prevent erosion, streambed scour, suspension of sediments, or excessive streamflow. Locations on pipeline dewatering, as well as any BMPs utilized, will be noted on the Site Plans as soon as such dewatering occurs. Additional information on stormwater dewatering is provided in the BMP Manual, discussed in Section 3.3. 3.3 Stormwater Manual of BMPs A Stormwater Manual of Best Management Practices (BMP Manual) is provided as Appendix E. The BMP Manual has been prepared to provide EnCana personnel, contractors, and subcontractors with information on the proper selection, design, installation, and maintenance of BMPs to manage oil and gas related stormwater and to meet federal and state SWMP implementation requirements. The main objectives of the BMP manual are to: • Serve as an easy-to-use guide for selecting, designing, installing, and maintaining BMPs. • Function as a reference for construction plans and specifications. • Ultimately lead to the avoidance of any net increase in off-site erosion and sedimentation of waters of the U.S. The BMPs within this BMP Manual are organized into four main types of controls for easy reference: Erosion Controls, Runoff Controls, Sediment Controls, and Non-stormwater Controls. Each of these types of controls has been discussed earlier in this section of the SWMP. 3.4 Phased BMP Implementation Various BMPs will be implemented and maintained during different phases of the project. A description of each phase is as follows: • Preconstruction. The preconstruction phase involves the installation of BMPs (temporary and/or permanent) around each site perimeter and at discharge points (such as vegetation buffers (no installation required for this BMP), slash, wattles, diversions, sediment basins and reservoirs, etc ... ). H:\Data\Stormwater Permits\Orchard Unit SWMP\Orchard Unit SWMP (Tombstone) 021508.doc 3-4 Revised February 2008 • Construction. The construction phase involves the stripping and stockpiling of topsoil, the excavation and backfill for access roads, pipelines, and well pads, and the installation of additional BMPs (preferably permanent BMPs) to control erosion and sedimentation (such as tracking topsoil piles and the installation of roadside channels, culverts, diversions, etc ... ). • Interim Reclamation. The interim reclamation phase primarily involves seeding of all disturbed areas not needed during operation of the well pads. However, this phase also involves the installation of any additional permanent BMPs that may be needed, as well as the continued maintenance and inspections of all BMPs until final stabilization occurs. Final stabilization occurs once all surfaces are built on, paved or graveled, and/or a uniform stabilized vegetative cover with a density of 70 percent of pre-disturbance levels has been established or when an equivalent permanent, physical erosion reduction-method has. been. employed~urther-explanation of-final-stabilization. is.provided-as-- - section 4 of this plan. • Final Reclamation. For pipelines, this phase involves seeding of all disturbed areas, and the installation of any additional permanent BMPs that may be needed, as well as the continued maintenance and inspections of all BMPs until final stabilization occurs. For other areas (roads, well pads, facilities, etc ... ), this phase (which may occur after termination of this permit and under the coverage of a new construction permit) occurs when operation of the area is no longer necessary. In these cases, this phase will include the installation of any additional BMPs required during facility decommissioning as well as the spreading of any remaining topsoil, the application of seed, and the inspection/maintenance of all BMPs until final stabilization occurs. Temporary controls, such as silt fencing, may be used to control sediment and erosion during preconstruction and construction activities. Permanent controls, such as diversions and sediment traps, may also be used during the initial phases of the project. However, only permanent controls will be used during interim reclamation and final stabilization. Temporary controls may be converted into permanent controls (such as revegetating a diversion) if needed. The primary control used during interim and final stabilization will be revegetation. Seeding will occur as soon as possible after disturbance of an area is complete. If the seeding is not successful, the area will either be reseeded or other controls will be put in place until reseeding can occur. H:\Data\Slormwater Permits\Orchard Unit SWMP\Orchard Unit SWMP (Tombstone) 021508.doc 3-5 Revised February 2008 4.0 Interim Reclamation and Final Stabilization As soon as practicable after construction activities have been completed in a disturbed area, interim (for well pads, or other facilities) or final (for roads and pipelines) reclamation will be started to prevent further erosion of soil from that area. This typically occurs immediately upon completion of earthwork activities. All disturbed areas (except for the surface of dirt roads, those portions covered by pavement or a structure, and those areas used during operation of a well) will be stabilized with permanent controls. The most common measure used to achieve final stabilization is revegetation. Mulching, erosion control blankets, surfacing with gravel or slash, and/or other methods may also be used. Structural controls (such as diversions, berms, and sediment traps) may be revegetated and used as permanent measures to control pollutants in stormwater discharges that will occur after construction operations have been completed. Appendix E includes detailed information on each of the previously discussed BMPs. In addition, a revegetation manual is provided as Appendix B, which provides guidance as to possible methods and materials needed to accomplish revegetation on differing site conditions. The specific BMPs used at each site are shown on the Site Plans which are kept with the Site Specific Records (Volume 2 of the Master SWMP). Final stabilization means that all ground surface disturbing activities at the site have been completed, and all disturbed areas have been either built on, paved, or a uniform vegetative cover has been established with an individual plant density of at least 70 percent of pre-disturbance levels, or equivalent permanent, physical erosion reduction methods have been employed. For purposes of this permit, establishment of a vegetative cover capable of providing erosion control equivalent to pre-existing conditions at the site will be considered final stabilization. Areas developed as stabilized unpaved surfaces as needed for operation of the facility after interim reclamation, will also qualify as "finally stabilized." This includes dirt road surfaces and the portions of the well pad surfaces that cannot be revegetated due to operational necessity, but does not include slopes, ditches, and other areas where revegetation is necessary. Stabilized unpaved surfaces will be prepared in such a way as to prevent ongoing erosion issues. Coverage under the Stormwater Construction Permit may be inactivated for any individual site or a portion/section of that site (i.e. the access road to a well pad) when the area has attained final stabilization and all temporary erosion and sediment control measures associated with that area have been removed. An area will be considered finally stabilized when construction and interim reclamation is complete and when the above final stabilization criteria have been met, even though the site may be disturbed again in the future for final reclamation. However, future land disturbances that follow final stabilization and result in disturbance of one acre or greater (such as final reclamation) will require new permit coverage at that time. Upon final stabilization of any site or portion/section of a site, a signed certification sheet (provided in Appendix F) will be placed into the Site Specific Records binder to replace the Site Plans and the inspection and maintenance records for that area. However, the Site Plans and inspection reports shall be retained in a separate location for a period of three years following final stabilization of the Permit Coverage Area. These documents will be made available to WQCD or EPA upon request and at the time of inspection. H:\Oata\Stormwater Permits\Orchard Unit SWMP\Orchard Unit SWMP (Tombstone) 021508.doc 4-1 Revised February 2008 5.0 Inspection and Maintenance Inspections and maintenance is an extremely important part of the Stormwater Construction Permit. The Construction Manager will ensure that all stormwater management controls are constructed or applied in accordance with governing specifications or good engineering practices. Experienced teams will be used for construction. A first inspection will occur upon installation of the controls. In addition, all workers on the site will be trained as to the location and use of the controls, especially those controls that will be disturbed as construction proceeds across the site. The goal is to minimize the potential for inadvertent removal or disturbance of BMPs and to prevent the off site transport of sediment and other pollutants. 5.1 Inspection Schedule Inspections are required as soon as the first soil disturbance occurs at the site. Once final stabilization of the site has occurred and the EnCana inspector has filled out the final stabilization certification sheet (see Section 4 ), inspections are no longer necessary. Specific information regarding inspection schedules are provided in the following sections. 5.1.1 Minimum Inspection Schedule for active sites The minimum inspection schedule applies to those sites under active construction, which includes the period from when the ground is initially disturbed to when construction activity is completed, and also includes the preparation of areas that will be revegetated for interim reclamation. During the Active Site period, a thorough inspectlon of the s1te storrnvvater management system ('vvhlch includes all uti!ized S~v1Ps) must be conducted at least every 14 calendar days. Also, post-storm event inspections must be conducted within 24 hours after the end of any precipitation or snowmelt event that causes surface erosion. There are three exceptions to the minimum inspection schedule which are described in detail within the next three sections: post-storm event inspections at temporarily idle sites (inspections required within 72 hours after a storm), inspections at completed sites (inspections required monthly), and inspections during certain winter conditions (inspections may not be required). Any use of an exception is temporary, and does not eliminate the requirement to perform routine maintenance due to the effects of a storm event or other conditions that may impact BMP performance, including maintaining vehicle tracking controls and removing sediment from impervious areas. Inspections, as described above, are required at all other times. 5.1.2 Post-Storm Event Inspections at Temporarily Idle Sites Temporarily idle sites are those where there are no construction activities occurring following a storm event. At such sites, post-storm event inspections must be conducted prior to restarting construction activities at the site, but no later than 72 hours following the storm event, and the delay noted in the inspection report. Routine inspections still must be conducted at least every 14 calendar days. 5.1.3 Completed Sites Once construction is completed and the site has been prepared for interim or final stabilization (including completion of appropriate soil preparation, amendments and stabilization practices), the site (or portion of the site) is considered a Completed Site (for purposes of the stormwater permit). Note: only construction activities that result in a disturbance of the ground surface must be completed. Construction activities that can be conducted without disturbance of the ground surface, such as certain well completion activities, would not prohibit a site from otherwise qualifying as a Completed Site. (Completed Sites still require permit coverage until the final stabilization criteria have been met) Completed Sites qualify for a reduced inspection schedule, as the potential for pollution is reduced if the site has been adequately prepared and/or seeded. However, because slopes and other disturbed areas may not be fully vegetated, erosion in these areas still occurs which requires maintenance activities such as regrading H:\Data\Stormwater Permits\Orchard Unit SWMP\Orchard Unit SWMP {Tombstone) 021508.doc 5-1 Revised February 2008 and seeding of problem areas. As such, inspections must continue in order to address these situations. During the Completed Site period, a thorough inspection of the site stormwater management system (which included all utilized BMPs) is required at least once every month. The SWMP must be amended to indicate those areas that will be inspected at this reduced frequency. 5.1.4 Winter Conditions Inspections Exclusion Inspections are not required at sites where construction activities are temporarily halted, snow cover exists over the entire site for an extended period, and melting conditions posing a risk of soil erosion do not exist. This temporary exclusion is applicable only during the period where melting conditions do not exist, and applies to the routine 14-day and monthly inspections, as well as the post-storm-event inspections. It is typical that when snow cover exists, even at a Completed Site, significant potential for erosion and BMP failure exists when melting does finally occur. Therefore, the site should prepared prior to snow cover to ensure it is as stabilized as possible, and be prepared to perform site maintenance when melt-off occurs, to alleviate any potential problems. Inspection records (see Section 5.4) will document that winter conditions exist and that inspections will be excluded. 5.2 Performing Inspections Inspections will be conducted by qualified personnel on the following areas: • All vegetated areas until 70% of pre-disturbance vegetation levels are reached. • All BMP measures identified in this document. • Construction site perimeter and discharge points. • All disturbed areas. • Areas used for storage of material/waste that are exposed to precipitation. • Other areas determined to have a significant potential for stormwater pollution, such as demolition areas or concrete washout locations, or locations where vehicles enter or exit the site. These areas will be inspected to determine if there is evidence of, or the potential for, pollutants leaving the construction site boundaries, entering the stormwater drainage system, or discharging to state waters. All BMPs will be evaluated to determine if they still meet the design and operational criteria in the SWMP and if they continue to adequately control pollutants at the site. Any BMPs not operating in accordance with Appendix E of this SWMP will be addressed as soon as possible, immediately in most cases, to minimize the discharge of pollutants, and the Site Specific Records will be updated. 5.3 Maintenance Maintenance activities will ensure that all control measures are functioning at optimum levels and that all procedures and techniques will be in proper working order during a runoff event or spill condition. Any maintenance, repairs, or replacements deemed necessary after required inspections will be corrected as soon as possible (if not immediately), to minimize the discharge of pollutants. Certain maintenance procedures may take a short period of time to make sure that all the proper safety precautions are in place, such as a "one call" for utilities, if the maintenance involves excavation of sediment located above a buried pipeline. Maintenance will include, but is not limited to: • Pickup or otherwise prevention of litter, construction debris, and construction chemicals from becoming a pollutant source prior to anticipated storm events. • Removal of sediment from silt fences, sediment traps, and other sediment controls. • Reseeding of any bare spots where vegetation has failed to establish. H:\Data\Stormwater Perrnits\Orchard Unit SWMP\Orchard Unit SWMP (Tombstone) 021508.doc 5-2 Revised February 2008 • Repairs and/or adjustments to any erosion and sediment control that is deteriorating or found to be performing inadequately. Detailed maintenance requirements for each BMP are identified in Appendix E. When maintenance is required, the following process will typically be followed: 1. Perform inspections according to the minimum inspection schedule discussed in Section 5.1. 2. Note the need for maintenance on the inspection and maintenance report form. 3. If necessary, collect the additional materials & resources needed to perform the maintenance activity. 4. Perform maintenance and note the date performed on the inspection and maintenance report form. 5. Re-inspect the area to ensure compliance. 5.4 Documenting Inspections and Maintenance The permittee must document inspection results, maintenance activities, and maintain a record of the results for a period of 3 years following expiration or inactivation of permit coverage. A typical inspection and maintenance report form is provided in Appendix G. Although the site may have a phased construction schedule, all construction areas may be inspected at the same time and on one form. Each well pad, road, pipeline, or other facility which is inspected shall be clearly written on the inspection form. Inspection reports will include the following: • Date of inspection, name of inspector, and title of inspector • The area inspected (Site ID), type of area (well pad, access road, pipeline, etc.), phase of construction (preconstruction, construction, etc.), and type of inspection (active, completed, etc.) • Site specific information including disturbed area, soil type(s), ecosystem/vegetation type(s), receiving waters, etc. • Vegetation observations including the percent pre-disturbance vegetation and whether or not vegetation growth has reached 70% of pre-disturbance levels • Specific inspection requirements (all BMPs and areas of potential pollutant sources) • Observed conditions including: Location(s) of discharges of sediment or other pollutants from the site Location(s) of BMPs that need to be maintained Location(s) of BMPs that failed to operate as designed or proved inadequate for a particular location Location(s) where additional BMPs are needed that were not in place at the time of inspection • Description and date(s) of corrective action(s) taken, and measures taken to prevent future violations • Changes necessary to the SWMP A hand drawn Site Plan shall be included, if necessary, to show the location(s) of any observed condition. After adequate corrective action(s) has been taken and recorded, or where a report does not identify any incidents requiring corrective action, the report will contain a signed statement indicating the site is in compliance with the permit to the best of the signer's knowledge and belief. All completed inspection and maintenance report forms (a blank copy of which is included in Appendix G) are kept with the Site Specific Records (Volume 2 of the Master SWMP). H:\Data\Stormwater Permils\Orchard Unit SWMP\Orchard 5-3 Revised February 2008 Unit SWMP (Tombstone) 021508.doc 6.0 Plan Revisions and Retention When BMPs or site conditions change, the Master SWMP (Volume 1) and/or the Site Specific Records (Volume 2) will be amended to accurately reflect the actual field conditions. Examples include, but are not limited to, removal of BMPs, identification of new potential pollutant sources, addition of BMPs, modification of BMP installation/implementation specifications or maintenance procedures, and changes in items included in the Site Plans. Changes to the Master SWMP (Volume 1) shall be noted on the SWMP Revisions log at the front of this plan. Changes to individual stte conditions will be noted in the Site Specific Records (Volume 2) on the applicable inspection and maintenance report form. All changes in Volume 1 and Volume 2 shall be made prior to actual changes in the site conditions, except for responsive SWMP changes, which shall be made immediately after changes are made in the field or as soon as practical, but in no case more than 72 hours after the change(s) in BMP installation and/or implementation occur at the site that require development of materials to modify the SWMP. At a minimum, the Master SWMP will be updated annually. The Master SWMP and the Site Specific Records will be retained at the EnCana field office in Parachute during active construction and site inspections to ensure accurate implementation and maintenance of BMPs, and required revisions. These documents will be retained for a period of three years following final stabilization of the Permit Coverage Area. These reports will be made available to WQCD or EPA upon request and at the time of inspection.

Prepared by: Westwater Engineering 2570 Foresight Circle #1 Grand Junction, CO 81505 September 2007 INTRODUCTION A field inspection of the proposed gathering system links and site was conducted by WestWater Engineering (WWE) biologists on August 28, 2007. Proposed routes are shown in Figure I, at the end of document. The inspection identified appropriate topics for inclusion in an integrated vegetation and noxious weed management plan required by Garfield County Regulation 9 .07 .04 (13) (BOCC 2006). Factors considered include soil type and texture, existing land management, absence or presence of listed noxious weeds and potential natural vegetation community. LANDSCAPE SETTING The trunk line is located adjacent to and north of U.S. Highway 6, partly through the Una industrial area. Terrain is gently sloping to moderately steep with east and south facing aspects. Soils on the pipeline route are Arvada loam, found with 1-6% slopes and ecological site salt flats, Arvada loam, found with 6-25% slopes (Photos 2 and 3), and Nihill channery loam found with 6- 25% slopes (NRCS 2007a). This is a harsh site with difficult soils and competition from unregulated invasive species. Photo 2. Arvada loam salt flats near east end Westwater Engineering Page 2 of 14 09/10/07 ) ) Photo 3. Wasatch Formation and derived soils Plants commonly seen in the area so il s include the species listed in Table I and their expected density. The Arvada loam salt flats site is particularly difficult with fine soils that expand and shrink (NRCS 2007a). Reclamation species are often difficult to find, expensive, and difficult to plant. Trees are non-existent on the route. Shrubs dominate the undisturbed landscape on the eastern half of the route. Table 1.

Previous ROW reclamation was fair to moderately successful on the westerly half of the proposed route. The easterly half of the existing ROW was poorly reclaimed with little to no reclamation species evident. Dominant species on this section are cheatgrass (Bromus tectorum) and field pennycress (Thlaspi arvense) an invasive but unregulated species. Another unregulated invasive species, white horehound (Marrubium vulgare) is present adjacent to the central portion of the pipeline and could be a problem in reclamation. The easterly half with fine, alkaline, sodic soils is an ideal section to inoculate with arbuscular mycorhizzal fungi (AMF) during reclamation. The Alternative Methods section provides further discussion of AMF. CURRENT AMOUNT OF INFESTED LAND NEEDING TREATMENT As stated previously, the pipeline is exposed to or infested with several problem weeds not regulated by Garfield County or State of Colorado (8 CCR 1203-19). Listed noxious weed species were found in low numbers and densities (Figure I, page 13). Other weeds observed are noted in the text, due to the adverse impact these species may have on reclamation through competition for moisture with desirable species. Only Garfield County listed weeds were mapped. Some species not listed in Garfield County are listed in adjacent jurisdictions, e.g., common mullein (Verbascum thapsis) is listed in nearby Rio Blanco County. Species in bold type in Table 2 are Garfield County listed noxious weeds observed in the field. Those in regular type were also observed and are listed by the State of Colorado as noted. Table 2.

The level of infestation of listed noxiou s weed s is quite low. Other weeds mentioned, e.g. cheatgrass, are far greater problem and challenge to successful reclamation (Photos 4 and 5). Photo 4.

Treatment strategies are different depending on plant type and are s ummariz ed in Tables 3 and 4. The Life Cycle and Management Calendar section and Table 6 illustrate be st timing and strategies for the noxious weeds found. Herbicides shou ld not necessarily a lways be the first treatment of choice when other methods can be effectively employed. Table 3.

Herbicides will be drawn down to the roots more efficiently at thi s time due to tran sloc ation of nutri ents to ro ots rather than leaves. If the weed patch has been present for a long period of time, another seaso n of see d production is not as important as getting th e herbicid e into the root system. Spraying in fall (after We stwater Engin ee ring Page 5of14 0 9/10/07 Table 4. Treatment Strategies for Perennials Target: Deplete 1111trie11t reserves in root system, preve11t seed prod11ctio11 middle August) will kill the following year's shoots, which are being formed on the roots at this time. 3 . Mowing usually is not recommended because the p lants will flower anyway; seed production should be reduced. Many studies have shown that mowing perennials and spraying the re-growth is not as effective as spraying without mowing. Effect of mowing is species dependent; therefore, it is imperative to know the species and its basic biology . Timing of application must be done when biologically appropriate which is not necessarily convenient. 4. Tillage may or may not be effective. Most perennial roots can sprout from pieces only Yi" -I" long. Clean machinery thoroughly before leaving the weed patch. 5. Hand pulling is generally not recommended for perennial species unless you know the plants are seedlings and not established plants. Hand pulling can be effective on small patches but is very labor intensive because it must be done repeatedly. (Sirota 2004) Herbicide treatment with two or more herbicide modes of action in fall (after approximately August 15 when natural precipitation is present) is the best method to control difficult species such as Russian knapweed (Photo 6). The res il ience and ability to quickly develop immunity to herbicides, particularly those used incorrectl y, makes it imperative to use the proper chemicals at the correct time in the specified concentration. Most misuse seems centered around excessive use either in frequency or concentration. This results in mostly top kill and an immune phenotype. Photo 6. R ussian knapweed Westwater Engineering Page 6of14 09/10/07 ) BEST MANAGEMENT PRACTICES The following practices should be adopted for any construction project to reduce the costs of noxious weed control. The practices include: • top soil, where present, should be segregated from deeper soils and replaced as top soil on the final grade, a process known as live topsoil handling; • wetland vegetation if encountered, should be live handled like sod, temporarily watered if necessary, and placed over excavated sub-soil relative to the position from which the wetland sod was removed; • cut-off collars should be placed on all wetland and stream crossings to prevent back washing or draining of important aquatic resources; • in all cases temporary disturbance should be kept to an absolute minimum; • equipment and materials handling should be done on established sites such as the northern point of origin to reduce area and extent of soil compaction; • disturbances should be immediately replanted with the recommended mix in the re- vegetation section; • topsoil stockpiles should be seeded with non-invasive sterile hybrid grasses if stored longer than one growing season; • prior to delivery to the site, equipment should be cleaned of soils remaining from previous construction sites which may be contaminated with noxious weeds; and • if working in sites with weed-seed contaminated soil, equipment should be cleaned of potentially seed-bearing soils and vegetative debris prior to moving to uncontaminated terrain. In areas with slope greater than 3%, imprinting of the seed bed is recommended. Imprinting can be in the form of dozer tracks or furrows perpendicular to the direction of slope. When hydro- seeding or mulching, imprinting should be done prior to seeding unless the mulch is to be crimped into the soil surface. If broadcast seeding and harrowing, imprinting should be done as part of the harrowing. Furrowing can be done by several methods, the most simple of which is to drill seed perpendicular to the direction of slope in a prepared bed. Other simple imprinting methods include deep hand raking and harrowing, always perpendicular to the direction of slope. Herbicides: Difficult species such as Russian knapweed (Photo 6) respond better to an application of a combination of two or more chemical modes of action (biological reason for plant death) rather than one (Boerboom 1999). It has also been found that use of two different groups of chemicals in the same mode of action can increase effectiveness on difficult species, e.g., phenoxys and benzoic acids or carboxylic acids and benzoic acids in a mix. Some come commercially pre- mixed, e.g., Crossbow and Super Weed-be-Gone Max, which are available over the counter. However, some of the most effective herbicides are restricted use and available only for licensed applicators. Professionals or landowners using herbicides must use the concentration specified on the label of the container in hand. Herbicides generally do not work better at higher concentrations. Most Westwater Engineering Page 7of14 09/10/07 herbicide failures observed by WWE are related to incomplete control caused by high concentrations killing top growth before the active ingredient can be transported to the roots through the nutrient relocation process. Most herbicide applications should use a surfactant if directed on the herbicide label or other adjuvants as called for on the herbicide label. Mechanical: Bull thistle and Russian knapweed found on the route are low enough in density and occurrence that control of these two species could be accomplished mechanically (Photos 6 and 7). Photo 7. Bull thistle Alternative Methods: Some noxious weeds are subject to damage from beneficial insects. Included are musk and plumeless thistle rosette weevil (Trichosirocalus horridus) and thistle defoliating beetle (Cassida rubiginosa), which feeds on the foliage of Canada, musk, and plumeless thistles (Sullivan 2004). Currently, infestations and noxious species found are candidates for insect control. Another alternative method, particularly for downy brome infestations and poor or destroyed topsoil, is the application of vesicular-arbuscular mycorrhizal fungi typically referred to as AMF. These fungi, mostly of the genus Glomus are symbiotic with about 80% of all vegetation. Endo- mycorrhizal fungi are associated mostly with grasses and forbs and could be helpful when reclaiming this project. In symbiosis, the fungi increase water and nutrient transfer capacity of the host root system by as much as several orders of magnitude (Barrow and Mccaslin 1995). Over-the-counter commercial products, which are better adapted to coating seeds when reseeding and treating roots of live seedling trees and shrubs at time of planting come in powder form and are available from many different sources. Some also come in granular form to be spread with seed from a broadcast spreader. The best AMF products should contain more than one species. Westwater Engineering Page 8of14 09/10/07 ) Some applicators, including a New Castle company, collect and grow local accessions of AMF. The latter are applied to weed patches and are reputed to greatly increase competition of native plants with Canada thistle in particular thereby affecting a non-chemical control of some noxious weeds. All Colorado State Forest Salida District tree and shrub plantings include the application of AMF. According to District Forester Crystal Tischler, "AMF is worth it" (Tischler 2006). Most if not all Colorado Department of Transportation re-vegetation/re-seeding projects now require use of AMF and BioSol, a certified by-product of the penicillin manufacturing process composed primarily of mycelium. Compacted soils respond well to fossilized humic substances and by- products called humates. These humates, including humic and fulvic acids and humin were formed from pre-historic plant and animal deposits and work especially well on compacted soils when applied as directed. RE-VEGETATION Soil types on the pipeline route support similar species of native vegetation. As stated previously, the recommended mix is limited to grasses due to the prevalence of field bindweed, halogeton and other weeds needing control with selective herbicides, and the need to use selective herbicides to spot treat for listed noxious weeds found in Table 2. The following mix (Table 5) is adapted from the seed mix used on the Tombstone Phase 1 project, as is considered appropriate for this project. Table 5.

The reseeding rate should be doubled for broadcast application. Preferred seeding method is multiple seed bin rangeland drill with no soil preparation other than simple grading to slope and imprinting and waterbars where applicable. Westwater Engineering Page 9of14 09/10/07 Alternative seedin g methods include but are not limited to: • harrow with just enough soil mo isture to create a rough surface, broadcast seed and re- harrow, preferably at a 90 degree angle to the first harrow; • hyd ro -seed in g (most economical in term s of see d cost); and • hand raking and broadcast followed by re-raking at a 90 degree a n g le t o th e first raking . • These are not the only means of replanting the site. However, these me th ods have been observed to be effective in similar landscap es. After desired grasses are established and control of target weed species is successful then shrubs, forbs and trees can be pla nted without concern fo r herbicide damage. Few native forb seeds are available commercially as cultivars. Most are collected from natural populations. Native s hrubs and forbs often do not establish well from seed, particularly when mixed with g rasses . Past experience has s hown that stabili z in g the so il with grasses, accomplishing weed contro l and then coming back to plant live; containerized woody species in copses has been th e most cost effective method for establishing the woody species component of the plant community.

(Sirota 2004) Westwater Engineering Page 11 of 14 09/10/07 COMMERCIAL APPLICATOR RECOMMENDATIONS A certified commercial applicator is a good choice for herbicide control efforts. An applicator has the full range of knowledge, skills, equipment and experience desired when dealing with Russian knapweed and other difficult vegetation. Reclamation farming services using multiple seed bin range drills and specialized related equipment is available and should be used for reclamation seeding projects. Common chemical and trade names may be used in this report. The use of trade names is for clarity by the reader. Inclusion of a trade name does not imply endorsement of that particular brand of herbicide and exclusion does not imply non-approval. Certified commercial applicators will decide which herbicide to use and at what concentration according to label directions. Landowners using unrestricted products must obey all label warnings, cautions, and application concentrations. The author of this report is not responsible for inappropriate herbicide use by readers.

Prepared by: Westwater Engineering 2570 Foresight Circle #1 Grand Junction, CO 81505 Septem her 2007 INTRODUCTION A field survey of the proposed trunk line right-of-way was conducted by WestWater Engineering (WWE) biologists August 28, 2007 . The proposed route is shown in Figure l , at the end of thi s document. The survey addressed topics for a wildlife impact statement and whether or not migration, use patterns, alteration of native vegetation or creation of hazardous attractions or refuge is an issue as required by Garfield County Regulation 5.03.07(1) [C] (BOCC 2006). LANDSCAPE SETTING The trunk line is located adjacent to and north of U.S. Highway 6, partly through the Una industrial area in an existing right-of-way (ROW) and utility corridor. Immediately north a few hundred feet is Interstate Highway 70. Terrain is gently sloping to moderately steep with east and south facing aspects (Photo I). Soils on the pipeline route are Arvada loam (Photo 2) , found with 1-6% slopes and ecological site salt flats , Arvada loam, found with 6-25% slopes , and Nihill channery loam found with 6-25% slopes (NRCS 2007). Photo 1. Wasatch Formation from which Wasatch Badlands soils are derived WestWater Engineering Page l of 9 pages 10 /17/2007 ) Photo 2. Arvada loam salt flats near east end Potential natural vegetation for soils affected includes the species listed in Table I and their expected density. The Arvada loam salt flats site is particularly difficult with fine soils that expand and shrink (NRCS 2007). Trees are non-existent on or near the route. Shrubs dominate the undisturbed landscape on the eastern half of the route but are not found in the ROW. Table 1.

Density of native vegetation on adjacent lands is low. Density for cheatgrass (Bromus tectorum) was more than 50% on adjacent vacant rangeland. Previous ROW reclamation was fair to moderately successful on the westerly half of the proposed route. The easterly half of the existing ROW was poorly reclaimed with little to no reclamation species evident. Dominant species on this section are cheatgrass and field pennycress (Th/as pi arvense ), an invasive but unregulated species. Another unregulated invasive species, white horehound (Marrubium vulgare ), could spread from nearby vacant rangeland and become problematic for reclamation. METHODS In addition to WWE biologist knowledge of the site, based on recent work on adjacent sites and long-term work in the region, Colorado Division of Wildlife (CDOW) personnel were contacted, the Natural Diversity Information Source was reviewed as was current published literature. A species occurrence checklist for the site was developed and is presented in Table 2. This list of wildlife species could be expected to be observed on or from the site during some period in the annual cycle. Wildlife observed or leaving evidence of use on the day of inspection is noted in bold type. The data, obtained from the CDOW County Species Occurrence database, was extracted and modified by WWE biologists based on the plant communities present at the site, potential wildlife using those plant communities during at least one season and experience from observing similar sites throughout the region (CDOW 2006, Fitzgerald et al. 1994, Andrews and Righter 1992, Hammerson 1999).

A portion lies between U.S. Highway 6 and Una Industrial Park. The once vacant rangeland appears to have been heavily grazed by sheep in the past. Recovery of the native vegetation community is nil. Potential impacts to wildlife species are assessed at different levels. From a landscape perspective, mega fauna, e.g., mule deer, elk, bald eagle and similar species with wide-ranging mobility are likely not affected by this project. Most of the species listed in Table 2 are migrants or passers-by, particularly mega-fauna like elk, mule deer and bald eagles and most other listed avifauna. Other wildlife, e.g., desert cottontail, deer mice, fence lizards and their cohorts, could be affected by a project such as this. However, the trunk line is not specifically located on or across any noted wildlife habitat feature previously identified by CDOW or U.S. Fish and Wildlife Service WestWater Engineering Page 5 of 9 pages 10/17/2007 as noteworthy, essential, or critical to any species known for this habitat in this part of the state. Wildlife values are very low in part due to the poor condition of the land and the industrial and other anthropomorphic impacts to the affected and adjacent land. A well-known local landscape-level wildlife issue in the vicinity is the American elk problem, which develops in late winter on nearby Colorado River meadows and bottomland. A group of elk arrive in late winter from Spring Creek, Wallace Creek and the Sunnyside area. Elk have not been regular winter residents of the Colorado River bottomland near the project area until recently. This new distribution is not an historic or desirable situation for elk. The abnormal movement and concentration is thought by the CDOW elk managers to be the result of late, special hunting seasons. CDOW has maintained several different late and special seasons due to undesirable numbers of elk on severe winter range and winter concentration areas on private land. Now, the elk sometimes assemble and end up trapped between Interstate 70 and U.S. Highway 6 in the vicinity of the west end of this trunk. A few wander onto the highways and are killed and cause major damage to vehicles. According to District Wildlife Manager, J. T. Romatzke, hunting seasons have undergone recent, major re-scheduling specifically target to prevent the abnormal distribution and concentration. Officials are hopeful the elk will remain southwest in an area known as Sunnyside (Romatzke 2007). WILDLIFE MITIGATION AND MANAGEMENT RECOMMENDATIONS Control Noxious Weeds. Timely reclamation and control of weed out-breaks will prevent spread from the trunk line. Regulated noxious weeds were observed in small numbers. These invasive species degrade wildlife habitat by replacing native vegetation. Minimize footprint of disturbance. Reduce to the minimum level possible all soil disturbing activities. Park construction vehicles on previously disturbed lands during construction to further reduce temporary disturbance. Re-seeding. Temporary and permanent disturbances are recommended to be re-seeded with native grasses. These measures should be described in an Integrated Vegetation and Noxious Weed Management Plan for this site. Best management practices such as the imprinting of un- vegetated slopes to reduce rill erosion should be implemented. Topsoil on finished grade has been eroded as can be seen in Photo 3. Merely imprinting with bulldozer tracks at right angle to slope would have prevented some loss of topsoil. Fence Removal. Wildlife un-friendly fences are located in the vicinity. If possible, old fence is recommended to be removed to enhance wildlife movement. Westwater Engineering Page 6 of 9 pages 10/17/2007 Photo 3. Rill erosion of newly applied topsoil.

Mineral Ave., Suite 10 Littleton, Colorado 80122 (303) 781-8211 www .Buysandassociates.com Revised by: Jake Jacobs EnCana Oil & Gas (USA) Inc. July 2005 INTRODUCTION It is the policy of EnCana Oil & Gas (USA) Inc. (EnCana) to comply with all environmental and safety rules and regulations. To implement this policy, it is necessary to provide for employee training, equipment, policies and procedures for preventative measures and immediate response for emergency incidents. An emergency incident includes spills, fires, blowouts, explosions or any act causing injuries or fatalities. Major incidents, or the cumulative effect of minor incidents, can cause complex and expensive technical, legal, governmental, and public relation problems for the company. It is not the intent of this manual to provide a step-by-step solution to every possible emergency incident. This manual will serve as a guide to assist EnCana personnel in the proper response to an emergency incident. REPORTING OF ALL EMERGENCIES OR INCIDENTS (Spills, Fires, Blowouts, Accidents, etc.) EnCana shall be notified according to ''Emergency Response Plan" protocol, of any and all fires, breaks, spills, leaks, or blowouts containing hydrocarbons or hydrocarbon waste or residue, salt water, strong caustic or strong acids, or other deleterious che1nicals or hannful conta1ninants occurring at EnCana drilling, producing, transporting, or processing facilities. In addition, all injuries, fatalities and vehicle accidents shall be reported to EnCana Operations Management and Environmental Health & Safety personnel, according to "Emergency Response Plan" protocol. Notification of such fire, break, leak, spill, blowout or any accident shall be in accordance with the provisions set forth below: Immediate Notification: Immediate notification shall be made as soon as possible after discovery (day or night) in accordance with "Emergency Response Plan" protocol. Situations requiring immediate_notification are as follows: 1) Blowouts 2) All fires 3) Any spill, break, or leak of one barrel or more 4) Any spill, break or leak which reaches a stream, lake or watercourse, including any lake bed, gully, draw, streambed, wash, arroyo, natural or man-made channel through which water flows, has flowed. or could flow. 5) Spills, breaks, or leaks which may with reasonable probability endanger human health, result in substantial damage to property, or endanger the health of livestock or wildlife. 6) All serious injuries, fatalities or vehicle accidents 7) Hydrogen sulfide emissions.idischarges In no event shall any personnel minimize the size of any spill, fire or blowout, nor shall they make the decision to delay reporting or b~gin cleanup operations. I. Purpose TECHNIQUES FOR CONTROLLING OIL DISCHARGES (LAND & WATER) ,&,., In spite of precautions taken, oil discharges can occur. Since the location and 1nagnitude of discharges can vary so greatly, this section was written to furnish general guidelines and usable techniques for containment of cleanup operations. II. Countermeasures A. Upon discovery of an accidental discharge the first action taken should be the safeguard of life and property. The next step would be to find the source of discharge and stop additional loss of fluid. I. Controllable Discharge: In most cases the amount of fluid being discharged is small and operations can be shut down to relieve power oil line or flowline pressure while installing a saddle clamp. The same is true when a valve is left open or tanks overflow. If possible the oil should be transferred into another storage tank or holding tank. 2. Catastrophic Discharge: The most damaging type of discharge usually occurs when a large volume of oil is lost in a short period of time. This is usually caused by ruptured tanks, equipment failure, or flowline breaks. In such cases the containment equipment and manpower should be concentrated well below the leading edge of the discharged oil. This will insure ample time for installation of containment dikes, dams and equipment. 3. Flammability: If discharged material is flammable and is located in a congested area, the local Fire and Police Departments should be notified immediately. rfhey in turn can initiate proper evacuation n1easures. Ill. Containment & Removal A. Fast action to contain the discharged fluid is of the utmost importance. It not only reduces the size of the area affected, it also reduces the cost of cleanup operations. The successful handling of any oil discharge depends on four different operations: I) Contain1nent 2) Rcinoval 3) Disposal 4) Cleanup IV. Mobilization A. The availability of equipment, material and labor is very important. Depending on the terrain and size of the discharge the following equipment may be needed; dozers, backhoe. tanks or vacuun1 truck, pu1nps, hose, boon1s, fencing, sorbent 1natcrials, po1iable light planL small boat, rubber boots, hand tools, communication system, etc. V. Discharges On Land A. Oil spills can come from many sources, however, the most common cause is power oil line or flowline leaks. The first rule for a land spill is, as always, containment. Confine the oil to the smallest area possible to reduce land damage and cleanup operations. In most areas. an earthen dam or dike can be constructed in the drainage flow to catch the oil. This will hold the oil for pick up by vacuum trucks. If groundwater (rain) is a problem, a retention pit can be dug with diversion ditches cut so that all spilled fluids drain into the pit. Vacuum trucks can then pick up the collected fluid. It may be necessary to install a siphon in the pit or dam if rainwater is a problem. A second dam or dike should always be maintained further down the drainage flow from where the oil is contained. If it becomes necessary to use this secondary dam, then immediately construct another further down the drainage flow. VI. Containment of Discharges fnto Water A. The first priority is lo limit the spread of oil to the smallest possible area. B. Floating Boom Development: Depending on water currents, a boom can be an effective means of controlling the spread of oil on water. Different conditions require the boom to be placed in certain configurations to utilize their containment potential. Generally, where river or water currents exceed 3 feet per second, containment is hindered. The oil will be forced under the barrier if the boom is placed perpendicular to the direction of water flow. Floating booms should be placed in such a way as to divert the oil to a calm area where removal may be accomplished. The types of boom development techniques commonly used are outlined in the following descriptions and diagrams: l. Oi 1 can be controlled along the shoreline adjacent to the point of discharge by tying one end of the boom to the shore and towing the loose end around the edge of the slick by boat or hand. Sorbent materials can then be placed in the slick, and removed by hand tools along the shoreline. Large spills can be ren1oved by vacuun1 pu1np or by to\ving the boon1 and encircled oil to a location where a skimming operation can be accomplished. This type of development is shown in the upper portion of Figure D-1. 2. The lower portion of Figure D-1 depicts an open Jake with the slick located offshore. ·1 hl.' bonn1 is anchored at one i:nd and to\ved around the slick to con1p!ctely ..:ncircle the oil. The oil can then be rc1novecl \Vith sorbcnt n1a1crial-.. J. In ;1 fr1-.,r. tlO\\·ing strearn (over 3 fect/st~cniHlj, the boon1 1nust be deployed tn di\lTi l!l<::'. ,_)if inlc1 a caln1cr area J(_ir the cen1oval operation. Iftlie strcarn is na1TO\V, the boo1n n1ay be tied to one bank and stretched across the strean1 in a configuration similar to that shown in the upper portion of Figure D-2. Best results will be accomplished when the boom is deployed at an angle less than 20° to the direction of flow. 4. The lower portion of Figure D-2 depicts a wide fast flowing river where the boom will not reach across the river. The current would wash the oil under the barrier if the boom was placed perpendicular to the water flow. A boom configuration must be employed which diverts the oil into a calm area for oil removal. The boom is tied to the shoreline at one end and attached to a mooring line at the other end to maintain the proper configuration to herd the oil. The boom should be placed at an angle less than 20° to the direction of flow. 5. In order to avoid loss of oil under a boom due to delays in removing the oil or to recover lesser amounts over a longer period of time (overnight), the construction of a skimming pond can be used. This technique is shown in Figure D-3. The use of several booms in conjunction with a skimming pond at the stream edge is also shown in Figure D-3. C. Expedient Booms: Described below are simple booms that can be constructed with materials available from local sources. I. Tie several bales of straw or hay (end to end) with steel wire. This acts as a sorbent boom. lfyou want to use it as a containment-type boom, just cover the bales with polyethylene sheets. The boom is attached to a cable and deployed across the stream. Figure D-4 describes this boom. 2. Logs or similar material can also be fastened together (end to end) and deployed across the water channel. Oil, however, passes more easily under this type barrier. This can be remedied by scattering floating sorbent materials in front of the barrier to help contain the oil. The barrier should also be placed at a sharper angle ( 10°) to the direction of flow. 3. Filter Fences: Filter fences can be used to control oil in ditches and streams where, generally, the water depth is fom feet or less. This type containment is very useful since it uses 1naterials available in 1nore areas at a 1nini1nal cost. This fence can be constructed with chicken or hog wire or chain link fence. Steel or wooden posts can be used for support and hay or straw used fi:ir the filter. Posts are driven into the stream bed 8-10 feet apart and set at an angle to current flow. The wire fencing is then tied to the post, always allowing at least one foot freeboard (wire above water level). Then anchor the fence to each bank of the stream. The straw or hay is broken out of the bales and spread over the water, the full width of the fence, for 15 to 20 feet back upstream. The depth of the straw or hay should be a minimum of 6 inches thick. In most cases there should be a series of these filter fences constructed leaving adequate working space between fences. These fences should always be continually 1naintained so the saturated stra\v or hay c<u1 be replaced as needed (Figure D-4). D. Flow Construction: It may be possible, where water flow rnlume is low, terrain permits, and sufficient time is available, to construct a catch basin in the stream channel or divert the water into holding ponds. This allows removal of oil by skimmer. vacuum trucks, etc. I. Siphon Dam: Figure D-5 illustrates two types of temporary catch basin construction using submerged pipe openings to carry water past the surface barrier which. iu turn, retains the floating oil. Care should be taken in selection of pipe diameter or number of pipes used to insure adequate discharge to prevent the dike from overflowing by trapped water.

Removal of Oil From Water A. Ideally, oil removal will be a two-stage operation. The first step is to consolidate the oil slick as much as possible. The greater oil thickness allows more efllcient use ofskirnmiug equipment. Oil recovered by this process can often be placed back into the production system and thus recovered. The second stage is to remove the remaining skim of oil. This is done by covering the slick with floating sorbent materials and retrieving the saturated materials by hand labor. 13. Practically, oil is diverted to the most suitable or accessible point where removal equipment can be located. Wind and water currents can be used to help float the oil into pockets for removal. However, wind and water currents can also hinder the operation. Always be aware of these two factors. VIII. Treating Agents A. Oil spill treating agents are generally classified as dispersants, collecting agents, sinking agents, burning agents, or gelling agents. 13. Chemical agents are not allowed to be used without prior approval of the EPA C. EnCana does not keep these chemical agents on hand and does not iutend for them to be used on any oil spill unless approval is received from the appropriate regulatory agency, and even then only with prior management approval. IX. Final Cleanup A. The final cleanup phase is to remove the oil stains on banks and vegetation bordering the spill area. The remaining contamination can be picked up by heavy equipment and removed to a disposal site. B. In order to protect the shoreline it may be necessary to strip the oil from vegetation by hand or flush with water into a holding pond. X. Disposal of Oil and Sorbent Materials A. The EnCana President or Operations Manager will determine what samples need to be taken and will evaluate what disposal options arc best for the particular site.

The project area contains no areas of critical environmental concern. Environmental Consequences/Mitigation: No impacts would occur and no mitigation measures are proposed. · CULTURAL RESOURCES Affected Environment: Pursuant to the following, a cultural resource inventory of federally managed lands and actions permitted by a federal agency must be undertaken prior to the agency considering the proposed surface disturbing actions -Historic Sites Act of 1935 (Pl 74-292), National Historic Preservation Act, 1966 (Pl 95-515), as amended (PL 102-575), National Environmental Policy Act 1969 (PL 91-190), Executive Order 11593, 1971 (16USC 470), Archaeological and Historic Data Preservation Act, 1974 (PL 93-291), American Indian Religious Freedom Act, 1978 (PL 95-341) and Native American Graves Protection and Repatriation Act 1990 (PL 101-601). The Proposed Action pipeline route and C02 amine treating facility was inventoried at a Class III level (100%) to determine whether cultural resources were present, and if present, the affect the Proposed Action would have on those resources. Uncompahgre Archaeological Consultants conducted a Class I literature search and review of the entire proposed pipeline route; and a Class III field examination of a segment of the proposed pipeline route that crosses ELM-administered public land, and American Soda and other private property north of Parachute. The on-the-ground inventory area consisted of a 150-foot corridor centered on the flagged centerline. The inventory also included areas of previous disturbance such as existing pipeline RO\Vs and highway ROW. In addition three areas of block inventory were conducted. Two of the areas proposed for staging areas, and one block area was on the western terminus of the pipeline at the proposed location of the C02 amine treating facility. Three segments of the pipeline on ELM managed lands were re-routed to avoid cultural resources or mitigate visual effects. These segments were inventoried at the same level and intensity as described above, with negative results. A total of 196 acres were inventoried at a Class Ill level. 11 A Class I literature review of the records at the Grand Junction and Glenwood Springs Field Offices, BLM and the Historical Society's Office of Archaeology and Historic Preservation was conducted for the entire pipeline conidor, with an approximate one- mile study area centered on the proposed route. The file search revealed that previous cultural resource inventories had been conducted in and around the proposed route. The ELM-administered public land had been inventoried for a pipeline, a portion of which the current proposed route parallels. The most notable previously recorded sites are 5GF959 (described below) and 5GF110. The Sisyphus Shelter was detennined to be eligible to the National Register of .Historic Places (NRBP), but was excavated and destroyed by construction ofl-70. A total of three prehistoric archaeological sites, ten prehistoric isolated finds and five Modern Features were recorded. Five locations were observed with cultural remains that appeared to be less than 50 years old. The sites and isolated finds were observed to be in areas where the surface has been eroded, indicating that there is a high potential for undiscovered subsurface sites. The three prehistoric archaeological sites -5GF959, 3183 and 3184 are field evaluated as eligible to the NRHP. The original pipeline route was moved to avoid affecting 5GF959, 3183 and 3184. Therefore, the Proposed Action would not affect the site. Environmental Consequences/Mitigation: Mitigation measures to avoid impacts to archaeological sites include pipeline reroute. The pipeline was relocated in two locations to avoid impacting archaeological sites 5GF959, 3183 and 3184. Although the route was moved to avoid affecting 5GF959, the proposed pipeline conidor lies adjacent to the nonheast corner of the site. The soils in th.is area appear to be at least 50 cm deep and sandy. A monitor during pipeline construction is recommended because subsurface cultural resources may be present and undiscovered. In addition, an education/discovery stipulation would be added to the ROW grant to stress the importance of th.is matter to EnCana' s employees and subcontractors. All persons who are associated with the project must be informed that if anyone is found disturbing historic, archaeological or scientific resources, including collecting artifacts, the person or persons could be subject to prosecution. Pursuant to 43CFRJ 0.4(g), the BLM authorized officer must be notified, by telephone, with written confirmation, immediately upon the discovery of human remains, funerary items, sacred objects, or objects of cultural patrimony. Further, pursuant to 43CFR10.4 (c) and (d), activities must cease in the vicinity of the discovery and the discovery must be protected for 30 days or until notified to proceed by the authorized officer. If, in connection with operations under this contract, EnCana and its contractors, subcontractors, or employees of any of them, discovers, encounters or becomes aware of any objects or sites of cultural or paleontological value or scientific interest such as historic or prehistoric ruins, graves or grave markers, fossils, or artifacts, the proponent shall immediately suspend all operations in the vicinity of the cultural or paleontological 12 resource and shall notify the BLM authorized officer of the findings (16 U.S.C. 470h-3, 36 CFR 800.112). Operations may resume at the discovery site upon receipt of v.'fitten instructions and authorization by t1e authorized officer. Approval to proceed will be based upon evaluation of the resource. Evaluation shall be by a qualified professional selected by the authorized officer from a federal agency insofar as practicable. When not practicable, the holder shall bear the cost of the services of a non-federal professional. Within five working days the authorized officer will inform the holder as to: • Whether the materials appear eligible for the NRHP; • The mitigation measures the holder will likely have to undertake before the site can be used (assuming in situ preservation is not necessary); and, • A time frame for the authorized officer to complete an expedited review under 36 CFR 800.11, or any agreements in lieu thereof, to confinn through the State Historic Preservation Officer that the findings of the authorized officer are correct and the mitigation is appropriate. The proponent may relocate activities to avoid tbe expense of mitigation and/or the delays associated with this process, as long as the new area has been appropriately cleared of resources and' the exposed materials are recorded and stabilized. Otherwise, the proponent will be responsible for mitigation costs. The authorized officer will provide technical and procedural guidelines for the conduct of mitigation. Upon verification from the authorized officer that the required mitigation has been completed, the proponent would then be allowed to resume construction. Antiquities, historic, prehistoric ruins, paleontological or objects of scientific interest that arc outside of the authorization boundaries but diJ:ectly associated with the impacted resource would also be included in this evaluation and/or mitigation. Antiquities, historic, prehistoric ruins, paleontological or objects of scientific interest, identified or unidentified, that are outside of the authorization and not associated with the resource within the authorization would also be protected. · Impacts that occur to such resources that are related to the authorization activities would be mitigated at the proponent's cost including the cost of consultation i.vith Native American groups. PALEONTOLOGY Affected Environment: Uncompahgre Paleo Consultants surveyed the paleontolo1,'1cal resources along the Pipeline ROW from I-70 to Logan Wash. This survey was performed in compliance with l\1EPA of 1969 (NEPA P.L. 91-190; 31 Stat. 852, 42 U.S.C. 44321- 4327) and FLPMA of 1976 (P.L. 94-579; Stat. 2743, U.S.C. 1701-1782). This survey sought to locate, identify, and.evaluate paleontological resources along the pipeline ROW for identification and potential protection. The proposed pipeline route overlies the Shire Member of the lower Eocene Wasatch Formation (approximately 55 million years old). The Shire Member contains alluvial plain sediments with a few channel sands and marginal lacustrine deposits with woody coal. Facies along the pipeline route include variegated red, purple, tan, and white rnudstones with fluvial sandstone and siltstone ioterbedding. · Despite several good outcrops within the study boundaries, no fossils were found. Other studies performed in or around the proposed EnCana pipeline ROW have reported no fossil localities. TI1e route seems to follow an interval of Jess smectitic (swelling) mudstones than typically seen stratigraphically higher in the section of Wasatch. The upper portion of the Shire member io the DeBeque area is more carbonate-rich and bears better-developed paleosols that seem to preferentially preserve fossils. Environmental Consequences/Mitigation: No impacts are anticipated to occur based on the lack of paleontological findings during the field survey. However, in the event a paleontological resource is found, the finding would be innnediately reported to the BLM authorized officer. The operator would suspend all operations in the immediate area of such discovery until written authorization to proceed is issued by the authorized officer. An evaluation of the discovery would be made by the authorized officer to determine 26 appropriate actions to prevent the loss of significant resources or scientific values. The operator would be responsible for tbe cost of evaluation and tbe authorized officer would make any decision as to proper mitigation measures after consulting witb the operator.

Due to Northwest Colorado's unpredictable weather, work in the ROW can create several types of hazards for the traveling public, contractors, and their personnel. The condition of the highway can change quickly. Mud tracked onto the highway by equipment, or ice and snowpack are just a few of the conditions that make the roadway more hazardous for all concerned. The terrain within the ROW must be kept clear of hazards as well. Holes, trenches, equipment and materials can make the terrain "unrecoverable" for a driver should his/her vehicle leave the highway. Activities must be shut down \Yhcn the roadway is other than dry. The use of frozen materials for backfilling will only lead to settlement. The contractor must make extra effort to compact the excavation. In the spring, any settlement of backfill shall be repaired. The re-vegetation shall take place yet this fall or early next spring.
