INTRODUCTION This Reclamation Plan (plan) describes measures to be taken by ETC Canyon Pipeline, LLC (Company) and its construction contractors (Contractor) for topsoil restoration, reseeding, planting, noxious weed control and reclamation monitoring. 1.1 PURPOSE The purpose of this plan is to describe in text and on drawings the prescribed methods for topsoil replacement, reseeding, planting noxious weed control, and monitoring for reclamation success. This plan is applicable to the construction on right-of-way (ROW) and extra workspace locations. 1.2 GOALS AND OBJECTIVES The short-term goals of reclamation are to control erosion and sedimentation and to minimize impacts to adjacent land uses. Properly executed construction practices and optimum scheduling will mitigate short-term impacts. Long term goals include controlling erosion and sedimentation; protecting water resources and soils; limiting the introduction and spread of noxious weeds; and returning disturbed areas to pre-existing condition. Monitoring during construction and post -construction will ensure that these goals are achieved. 1.3 ENVIRONMENTAL TRAINING The Company will conduct environmental training for all project personnel. Training will include topsoil protection measures and methods for controlling the spread of noxious weeds (e.g., maintaining clean vehicles and equipment). 1.4 RELATED PLANS / MAPS The following documents include additional requirements specifically related to the reclamation of the ROW and ancillary areas: • Soil Conservation, Sedimentation and Erosion Control Plan • Stream Crossing and Wetland Protection Plan • Hazardous Materials Management and Spill Prevention and Countermeasure Plan • Alignment Sheets 1.5 RESPONSIBILTIES Responsibilities are detailed below: 1.5.1 The Company The Company will be responsible for ensuring that the Contractor meets the standards defined in this plan to restore all disturbed areas to pre -construction conditions and to ensure long-term monitoring of restoration success. The Company will take remedial actions as necessary to restore and maintain a stable vegetative cover on the ROW. The Company will provide the Contractor with the appropriate blended seed mixes developed through consultation with agency representative and landowners. 1.5.2 The Contractor The pipeline Contractor will be responsible for post -construction re -seeding of the ROW, extra workspaces, and off -ROW ancillary sites following their construction activities. Reclamation will be conducted according to this plan as specified for the Contractor. 1.5.3 The Environmental Inspector The Environmental Inspector will have the responsibility to ensure field activities are performed in accordance with this reclamation plan by the Contractor and in compliance with all other permits and agreements. The Environmental Inspector will have the authority to make site-specific field changes in certain reclamation procedures within the guidelines of this plan in consultation with the landowner. 2. RECLAMATION PROCESS The following sections outline the pre -construction planning and sequential steps for restoring the ROW and extra workspaces following installation of the pipe and backfilling of the trench. However, one of the most important factors relating to successful reclamation takes place during the initial grading of the ROW. Topsoil salvage requirements and methods are discussed in detail in the Soil Conservation, Sedimentation, and Erosion Control Plan. 2.1 RECLAMATION ACTIVITIES The Environmental Inspectors, Soil Conservation Authority and Landowners will work to determine depth of topsoil, salvage, appropriate seed mixes, and seeding methods. 2.2 ROCK DISPOSAL "Excess rock" is defined as all rock that cannot be returned to the existing rock profile in the trench or graded cuts, or is not needed to restore the ROW surface to a condition comparable to that found adjacent to the ROW. This does not include tailings from boring operations. Excess rock will be randomly distributed across the ROW, piled or windrowed to create or enhance wildlife habitat, or arranged to block use of the ROW by motor vehicles. If not practical, the Contractor will remove other excess rock from the ROW and haul it to an approved disposal site. The Company will coordinate with landowners regarding the methods of disposal. 2.3 FINAL CLEANUP Within 30 days after backfilling the trench, the Contractor will make every effort to complete final cleanup and installation of permanent erosion control structures. The ROW and other project -related areas where soil has been disturbed will be restored as close to pre -excavation grades, compaction, and other conditions as possible, unless a specific exemption has been granted by the landowner. No solid waste, trash, or vegetative matter will be buried on the ROW. Final compaction of disturbed areas will be returned to approximate pre -construction conditions. In cases where this is not possible, e.g., steep slopes or rocky areas where full -ROW width topsoil salvage was not required, compaction will not vary more than 10 percent from adjacent off -ROW conditions. The Company will test soil compaction to a depth of 18 inches, if possible, at regular intervals using hand-held penetrometers or equivalent testing equipment and procedures. The Contractor will take remedial action as directed by the Company at all locations where compaction is not within the previously described 10 -percent limit. The Contractor will decompact excessively compacted areas with a paraplow, "Vibrashank," or other deep tillage implement. In areas where topsoil has been segregated, the subsoil will be decompacted prior to re -spreading the topsoil. In areas with a pre-existing rocky surface material, the Contractor will spread rock over the ROW to maintain a surface appearance similar to that of adjacent undisturbed terrain. Spreading rock on the surface will not be used as a method to dispose of excess rock except as described in Section .2.2. Where approved by the landowner and environmental Inspector, the Contractor will randomly distribute any windrowed shrubs or other remaining vegetation debris over the ROW. However, this must be accomplished by hand or light equipment (e.g., all -terrain vehicles) after seeding of the ROW so the spread material will not interfere with the performance of seeding equipment and to prevent disturbance of the seedbed. 2.4 TOPSOIL RESTORATION After the trench has been backfilled and the ROW regarded, the Contractor will redistribute topsoil to the approximate location from which it was originally removed. Restored topsoil will be left in a roughened condition to discourage erosion and enhance the quality of the seedbed. Topsoil will not be handled during excessively wet or frozen conditions as determined by the Environmental or Construction Inspector. Topsoil will be redistributed as close to original salvage depths as possible. Salvage methods are discussed in Section 2.2 of the Soil Conservation, Sedimentation, and Erosion Control Plan. Segregation of subsoil and topsoil will be maintained throughout final cleanup procedures. The Contractor will be responsible for replacement of lost or degraded (mixed) topsoil with topsoil imported from a Company -approved and weed -free source. Additional erosion control and soil stabilization will be required in areas adjacent to or within drainages. See the Soil Conservation, Sedimentation, and Erosion Control Plan and Stream Crossing and Wetland Protection Plan for additional information. 2.5 MISCELLANEOUS AGRICULTURAL FEATURES All irrigation ditches, drain tiles, cattle guards, fences, and artificial and natural livestock/wildlife water sources will be maintained and repaired to at least pre - construction conditions. Temporary measures will be provided, as agreed with the landowner, for any of these facilities that are disrupted during the construction or reclamation process. All drain tiles crossed by the trench line will be located and restored to the satisfaction of the landowner. Since the exact location or even the existence of drainage system may not be known prior to excavation, all drain tiles unearthed during excavation by the Contractor will be reported to the Company in writing. 2.6 SEEDBED PREPARATION The Contractor will scarify, till, or harrow the seedbed to a depth of 3 to 4 inches or as determined by the Environmental Inspector prior to seeding where needed to improve revegetation potential. Those sites where seedbed preparation is not practical (e.g., steep lopes, rocky areas, etc.) will be left with adequate roughness following topsoil placement to create micro -environments for seed germination and growth, and to reduce the potential for soil movement. 2.7 SOIL SUPPLEMENTS Generally, fertilizer will not be used unless requested by the landowner or recommended by either the Environmental Inspector or a soil conservation authority. At this time, no areas have been identified that require fertilizer. 2.8 REVEGETATION The Contractor will be responsible for seeding the ROW and off -ROW ancillary sites using Company -supplied seed mixes, appropriate seeding methods, and approved application rates. The seeding requirements and scheduling of reclamation activities will be determined in coordination with the Soil Conservation Authority or the appropriate landowner. 2.8.1 Species Selection and Sources Selection of grass and shrub species for revegetation will be based on pre - construction community composition and soil types as well as establishment potential, soil stabilizing qualities, commercial availability of regional varieties, post -construction land use objectives, and agency recommendations. Native species will be utilized to the extent possible unless non -natives are specifically requested by a private landowner or land managing agency. Project seed will be purchased from the blended by qualified producers and dealers. Certified weed -free or "blue -tagged" seed will be purchased for use on the project, but this status is only available for those native species with named varieties. All other seed will be free of primary noxious weeds. ETC Canyon Pipeline, LLC Oil & Gas (U.S.A.) Inc. will submit the seed for independent testing prior to its use. The Contractor will be responsible for providing all seed tags to the Environmental or Construction Inspector at the end of each day. On range lands, the following seed mix will be used: Pounds pure live seed (PLS)/Acre Luna Pubescent Wheatgrass 3.0 Paloma Indian Ricegrass 3.0 Arriba Western Wheatgrass 2.0 Rincon Rour-wing Saltbrush 1.0 Shadscale 1.0 Total 10.0 lbs PLS/Acre 2.8.2 Seed Application Rates and Viability Species ratios and Pure Live Seed (PLS) application rates will be developed in consultation with Landowners, agency specialists and other regional revegetation consultants. Seeding rates will be determined in PLS pounds per acre and seeds per square foot based on drilled application rates. Broadcast seeding rates will be twice the drill rate. Seed will be used within 12 months of testing to assure seed viability. If additional seeding is required in the year following construction, additional viability test will be conducted to determine any need for adjustment of application rates. The Contractor will seed wetlands, when necessary as determined by the Environmental Inspector. Successful recolonization by wetland species is generally related to effective topsoil salvage methods and sources of seed and rhizomes in adjacent areas. Streambanks will be seeded immediately upon completion of final cleanup as described in the Stream Crossing and Wetland Protection Plan and independent of other reclamation activities 2.8.3 Seeding Methods and Procedures The Contractor will employ broadcast or drill seeding as determined in the field by the Company. Seeding activities will be contingent upon weather and soil conditions, and subject to evaluation by the Environmental Inspector. Seeding will not be permitted if there is more than 2 inches of snow on the ground unless approved by the Environmental Inspector. Where approved by the landowner or land managing agency, the Contractor will randomly distribute any windrowed shrubs or other remaining vegetation debris over the ROW by hand or light equipment so as not to disturb the seedbed. 2.8.3.1 Drill Seeding Drill seeding will be employed wherever soil characteristics and slope allow effective operation of a range drill. Drill seeding will be performed perpendicular to the slope unless otherwise directed by the Environmental Inspector. The drill will have a seed release mechanism sufficient to allow seeds of various sizes and densities to be planted at the proper seeding depth. 2.8.3.2 Broadcast Seeding Broadcast seeding will be employed in all areas where drill seeding cannot be performed. Seed will be applied using manually operated cyclone - bucket spreaders, mechanical spreaders, blowers or hydroseeders. Seed will be uniformly broadcast over disturbed areas. Immediately after broadcasting, the seed will be uniformly raked, chained, harrowed, or cultipacked to incorporate seed to a sufficient seeding depth. If it is not possible to cover the seed with mechanical methods, the seeding rates will be doubled. 2.9 PERMANENT EROSION CONTROL Permanent erosion control methods will be utilized as needed for stabilization of slopes and soils as described in the Soil Conservation, Sedimentation, and Erosion Control Plan. Permanent erosion control measures will be installed within 30 days after the trench is backfilled to aid in site stabilization wherever required. 3. NOXIOUS WEED CONTROL Noxious weeds are spread through the dispersal of seeds or the transport of propagative plant parts. It is therefore important to reduce the sources of seed and viable plant material prior to construction disturbance and to prevent its transport or importation during construction. The combination of methods described below will be employed to minimize the potential for expansion of noxious weed populations via the pipeline route. 3.1 WEED CONTROL MEASURES DURING CONSTRUCTION The Company will require that all Contractor vehicles and equipment arrive at the work site clean, to prevent the importation of noxious weeds from a previous work site. Only after the Environmental Inspector has determined it to be free of soil, debris, or other potential sources of noxious weeds will any piece of equipment be allowed initial transport or access to the ROW. 4. WORKER SAFETY AND SPILL REPORTING All contracted herbicide contractors will obtain and have readily available copies of the appropriate application permits and the Environmental Protection Agency Material Safety Data Sheets (MSDS) for the herbicides being used. All reasonable precautions will be taken to avoid spilling herbicides. However, a spill kit will be carried in all herbicide applicator's vehicles to facilitate quick and effective response to a spill, should one occur. Herbicide spills will be reported in accordance with the requirements described in the project's Hazardous Material Management and Spill Prevention and Countermeasure Plan 5. RECLAMATION ASCHEDULE AND DOCUMENTATION Reclamation activities will be determined in part by construction schedules and seasonal climatic conditions. Seeding and planting will be coordinated with other reclamation activities to occur as soon after seedbed preparation as possible. Ideally, the Contractor will complete permanent reclamation activities prior to the end of the typical fall planting season (September 1st - October 31st ). Upon completion of reclamation, the Company's Construction Inspector, Environmental Inspector, and Land Agents, will perform a final inspection of the ROW and ancillary facilities to verify that pre -construction commitments have been satisfied. A copy of the post -reclamation inspection form will be transmitted to the Contractor is any deficiencies or a need for remedial action is noted. 6. POST -CONSTRUCTION MONITORING AND EVALUATION 6.1 REVEGETATION AND EROSION CONTROL MONITORING During the first growing season following construction and reclamation, qualified specialists will conduct intensive surveys to assess revegetation success and determine the need for further reclamation. Revegetation monitoring will include evaluation of the following parameters as compared to adjacent (off -ROW) vegetation: • percent total herbaceous cover (seeded species plus desirable volunteers), and • species composition Where applicable, the following will be evaluated: • new or expanded populations of noxious weeds. Areas with poor germination and/or growth will be evaluated to determine, if possible, the cause of the problem. Reclamation techniques will be modified as necessary to address any identified problems and appropriate remedial measures will be undertaken. The Contractor will be responsible for remediating any problem areas identified by the Company for the first growing season following construction. Thereafter, the Company will be responsible for obtaining a reclamation contractor to perform any necessary work. Erosion control monitoring will be performed in response to significant weather events and/or concurrently with the revegetation monitoring during the first year following construction. Success criteria for both are discussed in Section 6.2. Both erosion control and revegetation monitoring will be conducted routinely throughout the life of the pipeline to evaluate long-term survival of reestablished vegetation and the effectiveness of erosion control measures with specific attention to problem sites. 6.2 EVALUATING RECLAMATION SUCCESS The Company is responsible for the stability and revegetation of all areas disturbed as a result of construction for the life of the pipeline. As discussed in Section 6.1, the Company will conduct intensive monitoring after the first growing season and routinely thereafter to assess soil stability and revegetation success. The Contractor will reseed any portion of the ROW that does not exhibit 50 percent total herbaceous cover (comprised of seeded species plus desirable volunteers) relative to adjacent (off -ROW) vegetation after the first complete growing season. Additional seeding will be completed during the next seeding season (fall or spring). In the event that first year revegetation is affected by precipitation amounts significantly below the annual average, the Company may request deferment of additional seeding activities until the following seeding window. The reclaimed ROW will be considered stable when the surface appears similar to adjacent undisturbed land and the following accelerated erosion indicators do not exist: • Perceptible soil movement (exceeding pre -construction conditions) • Head cutting in drainages • Flow pattern development resulting in large (greater than 12 inches in depth) rills or gullies • Trench subsidence or slumping Revegetation will be considered successful when the following criteria are met: • Total herbaceous (seeded species plus desirable volunteers) cover is at least 75 percent of that on adjacent land, • Species composition comprised of a mix of seeded species and desirable volunteers from adjacent communities, and Fire Prevention & Suppression 1.

INTRODUCTION The Fire Prevention and Suppression Plan (plan) identifies measures to be taken by ETC Canyon Pipeline, LLC (Company) and its contractors (Contractor) to ensure that fire prevention and suppression techniques are carried out in accordance with federal, state, and local regulations. Measures identified in this plan apply to work within the project area defined as the right-of-way (ROW), access roads, all work and storage areas, and other areas used during construction of the project. 2. PURPOSE The risk of fire danger during pipeline construction is related to smoking, refueling activities, operating vehicles and other equipment off roadways, welding activities and the use of flammable liquids. During pipeline operation, risk of fire is primarily from unauthorized entry onto the ROW. During maintenance operations, risk of fire is from vehicles and pipeline maintenance activities that require welding. This plan establishes standards and practices that will minimize the risk of fire danger and, in case of fire, provide for immediate suppression. 3. RESPONSIBILITIES AND COORDINATION This plan will be implemented by the Company and the Contractor on the project. The Company and the Contractor have the responsibility for providing all necessary fire -fighting equipment on the project site to their respective employees, and operating under the requirements of this plan. Prior to construction, the Company will contact the appropriate authorities to establish communications, obtain permits (if applicable), and/or fulfill other obligations as directed by fire control authorities. In addition to the above, the Company will: • Ensure that prevention, detection, pre -suppression, and suppression activities are in accordance with this fire plan and federal, state and county laws, ordinances, and regulations pertaining to fire. • Accompany agency representatives on fire tool and equipment inspections and take corrective action upon notification of any fire protection requirements that are not in compliance; and The fire prevention and suppression measures described in this plan will be in effect from June 1 to the end of construction. These dates may change by advance written notice by fire control authorities. However, required tools and equipment will be kept in serviceable condition and be immediately available for fire suppression at all times. 4. FIRE PREVENTION MEASURES 4.1 PRECONSTRUCTION AND CONSTRUCTION Methods and procedures that will be implemented prior to and during the construction period to minimize the risk of fire are described below. 4.1.1 Training Contractor will train all personnel about the measures to take in the event of a fire. Contractor will also inform each construction crewmember of fire dangers, locations of extinguishers and equipment, and individual responsibilities for fire prevention and suppression during regular safety briefings. Smoking and fire rules will also be discussed with the Contractor and all field personnel during the project's environmental training program. 4.1.2 Smoking Smoking is prohibited in areas cleared and graded a minimum of 10 feet in diameter to mineral soil. All buming tobacco and matches will be extinguished before discarding. Smoking is also prohibited while operating equipment or vehicles, except in enclosed cabs or vehicles. 4.1.3 Spark Arresters During construction, operation, maintenance, and termination of the ROW, all Contractor and Company equipment operating with an internal combustion engine will be equipped with federally approved spark arresters. Spark arresters are not required on trucks, buses and passenger vehicles (excluding motorcycles) that are equipped with an unaltered muffler or on diesel engines equipped with a turbocharger. A Garfield County fire prevention officer will have full authority to inspect spark arresters on project equipment prior to its use on the project on federal lands and periodically during the construction project. 4.1.4 Parking, Vehicle Operation and Storage Areas In no case will motorized equipment, including worker transportation vehicles be driven or parked outside of the designated and approved work limits. Equipment parking areas, the ROW, staging areas, designated vehicle -parking areas, and small stationary engine sites, where permitted, will be cleared of all flammable material. Clearing will extend a minimum of 10 feet beyond the edge of the area to be occupied, but not beyond the boundaries of the approved ROW, extra workspace, or ancillary site. Glass containers will not be used to store gasoline or other flammables. 4.1.5 Equipment All motor vehicles and equipment will carry one long -handled (48 -inch minimum) round -point shovel, and one dry chemical fire extinguisher (5 pounds minimum). Individuals using power saws and grinders will have a shovel as described above, and an 8 -ounce capacity fire extinguisher immediately available. The Fire Guard will operate a truck equipped with a 125 gallon slip-on pump unit designed for wildlife firefighting. All equipment will be kept in a serviceable condition and readily available. 4.11 Restricted Operations The Contractor will restrict or cease operation on federal lands during periods of high fire danger at the direction of the responsible Garfield County Officer. The Contractor will restrict or cease operations during periods of high fire danger at the direction of the Garfield County Sheriff's Office Fire Marshal. Restrictions may vary from stopping certain operations at a given time to stopping all operations. The company may obtain approval to continue some or all operations if acceptable precautions are implemented. 4.12 Monitoring Construction and Environmental Inspectors for the Company will inspect the job site and the Contractor's operations for compliance with all provisions of this plan. In addition, federal, state, and local fire control agencies may perform inspections in areas under their jurisdiction at their discretion. 4.2 PIPELINE OPERATION During pipeline operation, the risk of fire danger is minimal. The primary causes of fire on the ROW result from unauthorized entry by individuals utilizing the ROW for recreational purposes and from fires started outside of the ROW. In the latter case, the ROW can be used by authorities as a potential fire break. During pipeline operation, access to the ROW will be restricted, in accordance with landowner requirements, to minimize recreational use of the ROW. 4.3 PIPELINE MAINTENANCE During maintenance operations, the Company or its Contractor will equip personnel with basic fire -fighting equipment including fire extinguishers, and shovels as described in Section 4.1.5 Equipment. Maintenance crews will also carry emergency response/fire control contact phone numbers. 5. FIRE SUPPRESSION 5.2 SUPPRESSION Contractor will take the following actions should a fire occur within the project area during construction. • Take immediate action to suppress fires using all available manpower and equipment. Notify the Fire Guard. • Immediately notify the nearest fire suppression agency of the fire location, action taken, and status (refer to Fire Suppression Contacts for a list of fire suppression agencies and emergency phone numbers). • Relinquish the Fire Guard's direction of fire suppression activities to agency fire management officers upon their arrival. If a reported fire is controlled, the Fire Guard will note the location and monitor the progress in extinguishing the fire. The Fire Guard, or their designee, will remain at the fire scene until it is fully extinguished. The extinguished fire will be monitored in accordance with procedures described in Section 5.2 below. Fire Suppression Contacts Construction Phone Number Office Location Garfield County Garfield County (970) 625-8095 Garfield County Dispatch Center Private and State Lands, Colorado Garfield County (970) 285-9127 Garfield County Sheriff's Office in Parachute 5.2 MONITORING Contractor will mark the location and boundaries of all extinguished fires. The extinguished fire site will be monitored by the Contractor for a minimum of 24 hours. Monitoring includes walking the fire site perimeter, as well as crossing through the site. The Fire Guard will maintain a log of all extinguished fire locations for future reference. 6. NOTIFICATION 6.1 NOTIFICATION PROCEDURES Construction crewmembers will report all fires, whether extinguished or uncontrolled, to the Fire Guard. If the fire is uncontrolled, Contractor's Fire Guard will call the nearest fire suppression agency (refer to Fire Suppression Contacts), and the Company. Information regarding the location of the fire, property ownership, and closest access roads should be provided to the Dispatch Office and the Company. If a reported fire is controlled, but not extinguished, the Fire Guard will call to notify the nearest fire suppression agency to alert them of the situation. The status of the fire will be monitored by the Fire Guard and when extinguished, the nearest fire suppression agency will be notified. See table for a list of fire suppression contacts.

INTRODUCTION This Hazardous Materials Management and Spill Prevention and Countermeasure Plan (HAZMAT Plan) describes measures to be taken by the ETC Canyon Pipeline, LLC (Company) and its contractors (Contractor) to reduce the risks associated with the use, storage, transportation, production, and disposal of hazardous materials (including hazardous substances and wastes) and petroleum products. In addition, this plan outlines the required spill prevention and response (cleanup) procedures for the project. The HAZMAT Plan prepared as part of the Stormwater Pollution Prevention Plan as required by the project's National Pollution Discharge Elimination System (NPDES) permit for stormwater discharges. This plan was prepared in accordance with good engineering practices. In general, hazardous materials and clean-up equipment will be stored at the construction yard. Materials Safety Data Sheets (MSDS) will be maintained at the Contractor's yard(s) throughout the construction period. The Contractor will prepare and have the Company review and approve a HAZMAT Plan prior to any storage of hazardous substances or petroleum products. The company will have 10 days to review submitted plans. 1.1 PURPOSE OF PLAN The purpose of this plan is to provide a description of hazardous materials management, spill prevention, and spill response/cleanup measures associated with the construction, operation, and maintenance of the project. In addition this plan provides Contractors with requirements and guidance for the creation of their own HAZMAT Plan. 1.2 OVERVIEW OF THE PLAN'S COMPONENTS This plan includes the following components: (1) an introduction; (2) a description of the spill prevention procedures related to vehicle refueling and servicing and the transportation, storage, and disposal of hazardous materials; (3) guideline for developing the Contractor's HAZMAT Plan; (4) a description of the physical and procedural methods for spill control and cleanup; and (5) an overview of the notification and documentation procedures to be followed in the event of a spill. 1.3 PLANS AND MAPS RELATED TO THE HAZMAT PLAN Construction Alignment Sheets: These maps show the locations of drainages, waterbodies (defined as flowing streams and rivers), wetlands, and other sensitive resource areas. Fire Suppression and Prevention Plan: This plan details measures to be taken to reduce the risk of starting a fire, and measures to be implemented in the event a fire does occur within the project construction area. Stream Crossing and Wetland Protection Plan: This plan provides detailed information on measures that will be implemented during construction to avoid and/or minimize project -related impacts to waterbodies and wetlands. 1.4 REGULATORY OVERVIEW Major legislation pertaining to hazardous materials includes the Comprehensive Environmental Response, Compliance, and Liability Act (CERCLA), the Resource Conservation and Recovery Act (RCRA), the Clean Air Act, and the Clean Water Act. Numerous other federal, state, and local regulations also govern the use, storage, transport, production, and disposal of hazardous materials. Some of the key requirements of these laws are outlined in the following: • Title 29, CFR, Part 1910.1200 (Hazardous Communication Standard). Title 27, CFR, Part 55 (storage and use of explosives) • Title 40, CFR, Parts 112, 260 to 263, and 279 (hazardous wastes definitions, standards for hazardous waste generators, and requirements for Spill Prevention Control and Countermeasure Plans) • Title 49, CFR, Part 171-180 (hazardous materials transportation) • Superfund Amendments and Reauthorization Act (SARA) Title III, Section 301-303 (emergency planning), Section 304 (emergency release notification), and Section 311/312 (community right -to -know reporting requirements) This plan is intended to comply with and compliment existing regulations pertaining to the safe use of hazardous materials. Persons responsible for handling hazardous materials for this project will be trained in the proper use/management of the materials and will be familiar with all applicable laws, policies, procedures, and best management practices (BMP's) related to them. 2. CONTRACTOR'S GUIDELINES FOR DEVELOPING THE HAZMAT PLAN The following sections provide specific guidelines for the preparation of the HAZMAT Plan by Contractor. 2.1 CERTIFICATIONS, ACKNOWLEDGEMENTS AND DESIGNATION OF COORDINATOR RESPONSIBLE PERSON(S) 2.1.1 Certifications Contractor will certify that all of the information provided in the HAZMAT Plan is accurate and complete to the best of their knowledge. Contractor will also certify that they are committed to implementing the HAZMAT Plan as written. As per the requirements of 40 CFR, Part 112, Contractor will have the HAZMAT PLAN reviewed and certified by a registered Professional Engineer. 2.1.2 Amendments In completing this certification, Contractor will agree to make all necessary and appropriate amendments to the plan and submit any such amendment to the Company and the appropriate county, state, and/or federal authorities within 7 days of finding an amendment is necessary. Amendments to the plan will be necessary under any of the following circumstances: • 100 percent or more increase of a previously disclosed material, • any handling of a previously undisclosed hazardous material subject to inventory requirements, O a change of business address, name, or ownership. 2.1.3 Responsible Person(s) Contractor is responsible for contacting county representatives to determine county requirements for Hazardous Materials Business/Management Plans. Generally counties will provide guidelines and forms for completion and submittal to the county. As required on the applicable county forms that the Contractor will obtain, Contractor will designate a primary emergency coordinator for hazardous materials management and emergency response. Two alternates will also be identified. Business, residential, and cellular or pager telephone numbers will be provided for all three persons as necessary, to allow for contact on a 24-hour basis. Primary and alternate emergency coordinators will be knowledgeable of the chemicals and processes involved in Contractor's operation. They will have full access to all facilities, including locked areas, and must have the authority to commit company resources. They will also have stop work authority to prevent impacts (potential or actual) to environmental resources. 2.2 FACILITIES' DESCRIPTION AND INVENTORY OF MATERIALS Contractor's submittals will be provided to the Environmental Inspector. The Environmental Inspector will provide submitted information to the jurisdictional agencies as appropriate. 2.2.1 Site Map Contractor will complete the relevant county forms related to business information and description. The Contractor is also required to provide a site map/facility map for each construction yard indicating storage and safety precautions for hazardous materials and hazardous wastes. The Contractor's site map will, at a minimum, indicate the following: • orientation and scale • total land area in square feet • access and egress points • building and/or temporary trailers • parking lots • adjacent land uses (if business, indicate business name) • surrounding road, storm drains, ad waterways (including waterbodies and wetlands) • locations of hazardous materials and hazardous waste storage • underground and above ground tanks • containment or diversion structures (dikes, berms, retention ponds) • shutoff valves and/or circuit breakers • location of emergency response materials and equipment • location of MSDS and HAZMAT PLAN • location of emergency assembly area • location of clean up equipment within the yard As noted in Section 3.6 — Storage of Hazardous Materials, hazardous materials will be stored only in designated staging areas 100 feet from streams (dry and wet) and wetlands (dry and wet) and equipment storage yards. Temporary pumps, diesel powered generators, etc., will be located at least 100 feet from the edge of streams (dry and wet), wetlands (including dry or seasonal wetlands), and other sensitive areas defined by the project's Environmental Inspectors. If storage areas cannot be located at least 100 feet from streams and wetlands because of topographic conditions or space, the Contractor will also provide a sketch of where the materials will be stored in relation to the waterbody and location of clean up equipment. Include measures to be implemented for secondary containment as specified in Section 3.6.1, Physical Storage Requirements. 2.2.2 Inventory Contractor will provide a complete inventory to the Company of all hazardous substances that will be used (refer to Title 40, CFR, Parts 116 and 302). All inventory forms required by the relevant county will be provided by the Contractor as part of their HAZMAT Plan. 3. HAZARDOUS MATERIALS MANAGEMENT Construction, operation, and maintenance of the project will require the use of certain potentially hazardous materials such as fuels, 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 their quantity, concentration, or chemical composition. Generally, hazardous materials will be stored in the Contractor's yard and not on the right-of-way (RO). When stored, used, transported, and disposed of properly as described below, the risks associated with these materials can be reduced substantially. 3.1 OVERVIEW OF HAZARDOUS MATERIALS PROPOSED FOR USE The following project -specific measures pertain to all vehicle refueling and servicing activities as well as the storage, transportation, production and disposal of hazardous materials (substances/wastes). These measures are intended to prevent the discharge of fuels, oils, gasoline, and other harmful substances to waterbodies, groundwater aquifers, and/or other sensitive resource areas during project construction. Hazardous materials (substances) used during project construction may include solvents and other substances. In addition, petroleum products such as gasoline, diesel fuel, lubricating oils, and hydraulic fluid will be used. Some of these materials will be used in relatively large quantities at staging areas, in storage yards, and on the ROW to operate and maintain equipment during construction. Smaller quantities of other materials such as: herbicides, paints, and other chemicals will be used to control noxious weeds and facilitate revegetation on the row, and to operate and maintain meter stations during the life of the project. Additional materials will be necessary at other locations along the ROW (e.g., river crossing, hydrostatic test stations) and at off -ROW construction yards. Listings of other hazardous materials that will be used during construction, operation, and maintenance of the project in other locations will be identified on the Contractor's Hazardous Substances Inventory form included in Attachment 1. The Company will compile all Contractor's submittals and update Attachment 1 prior to start of construction. The Company will update the inventory of hazardous materials used/stored on the project as needed throughout the life of the project. This information will be provided to the appropriate regulatory agencies as required. 3.2 TRAINING All project personnel will be required to receive basic spill prevention training. The Company is required to maintain a record of those workers who have received environmental training and ensure that only trained employees are allowed to work on the project. In addition all Contractor personnel who will be involved with the transportation and storage of fuels or hazardous substances, equipment maintenance, and spill response will be required to attend a higher level training class given by the Contractor as described in Section 5.2. 3.3 VEHICLE REFUELING AND SERVICING Construction vehicles (e.g., trucks, bulldozers, etc.) and equipment (e.g., pumps, generators, etc.) will be fueled/serviced in designated upland staging areas at least 100 feet from waterbodies and wetlands (including dry streams and dry or seasonal wetlands, refer to the stream and wetland crossing list in the Stream Crossing and Wetland Protection Plan). If pumps, generators, etc. cannot be located at least 100 feet from streams and wetlands because of topographic conditions or space limitations, special precautions (e.g., placing pumps and small refueling cans in secondary containment structures) will be taken to prevent the spill or release of hazardous materials into the waterway. Fueling will not occur within 200 feet of private wells or 400 feet of municipal wells. When selecting refueling areas, consideration will be given to slopes and other topographic conditions. Refueling locations will generally be flat to minimize the chance of spilled substance reaching a waterbody. In most cases, rubber -tired vehicles will be refueled and serviced at local gas stations or equipment yards off the ROW. Tracked vehicles will typically be refueled and serviced by fuel/service vehicles on the ROW. Every effort will be made to minimize the threat of a fuel spill during refueling and servicing. Fuel/service vehicles will carry extra plastic, a bucket or plastic pan to catch fuel, and minimum of 20 pounds of suitable absorbent material to handle potential spills. In addition, all vehicles will be inspected for leaks prior to being brought on-site and regularly throughout the construction period. In the event that a leak(s) is found, equipment will not be allowed to operate until all leaks have been repaired. Vehicles will also be equipped with fire fighting equipment as specified in the Fire Prevention and Suppression Plan. Construction equipment requiring maintenance which might result in the draining or leaking of fluids will be serviced only after a 12 mil plastic liner has been installed between the equipment and the soil. This liner must be placed in such a manner that all fluid is contained. Washing of construction vehicles (such as concrete trucks) will be allowed only in construction staging areas at least 100 feet from waterbodies and wetlands (including dry streams and dry or seasonal wetlands). Washing areas will be contained with berms or barriers to prevent migration of wastewater and/or sediments into waterbodies. Waste concrete material will be removed and properly disposed of once it has hardened. 3.4 EQUIPMENT ISPECTION AND DECONTAMINATION Prior to moving equipment onto the ROW, the Environmental Inspector will check equipment for leaks while also inspecting the equipment for weeds. All equipment will be cleaned and weed -free prior to being moved to the ROW. Equipment contaminated from fuel or hydraulic line breaks will be cleaned with diapers and the diapers will be disposed of properly. 3.5 TRANSPORTATION OF HAZARDOUS MATERIALS Procedures for loading and transporting fuels and other hazardous materials will meet the minimum requirements established by the Department of Transportation (DOT) and other pertinent requirements. At all times, hazardous materials will be transported in DOT approved containers. Prior to transporting hazardous materials, appropriate shipping papers will be completed. Vehicles carrying hazardous materials will be equipped with shovels, barriers tape, 4 to 6 mil plastic bags, personal protective clothing, and spill pads to contain a small spill should one occur during transport. In addition, vehicles transporting such materials will be properly signed (placarded) and/or marked. Prior to transporting hazardous materials, vehicles will be inspected for leakage and other potential safety problems. The Contractor will ensure that vehicle drivers are properly trained to respond to and report spills, leakage, and/or accidents involving hazardous materials (see Section 5.2 of this plan). All hazardous materials used for the project will be properly containerized and labeled at all times, including during transportation. Smaller DOT approved containers will be used on-site to transport needed amounts of hazardous materials to a specific location. Transfer of materials from large to small containers will not be done by hand pouring, but will be accomplished using appropriate equipment including pumps, hoses, and safety equipment. These smaller ("service") containers will also be clearly labeled. 3.6 STORAGE OF HAZARDOUS MATERIALS Hazardous materials will be stored only in designated staging areas 100 feet from streams (dry and wet) and wetlands (dry and wet) and equipment storage yards. Temporary pumps, diesel powered generators, etc., will be located at least 100 feet from the edge of streams (dry and wet), wetlands (including dry or seasonal wetlands), and other sensitive areas defined by the project's Environmental Inspectors. If storage areas cannot be located at least 100 feet from streams and wetlands because of topographic conditions or space limitations, special precautions will be taken to prevent the spill or release of hazardous materials into the waterway. These precautions will include limiting the quantity and amount of time such materials are stored near the stream or wetland, providing secondary containment, and using trained personnel to monitor activities at the storage site. Storage of greater than 55 gallons of hazardous materials will not be permitted within 100 feet of streams or wetlands. Cleanup materials, including absorbent spill pads and plastic bags, will also be stored in these areas. Hazardous materials will not be stored in areas subject to flooding or inundation. 3.6.1 Physical Storage Requirements Security: Hazardous materials will be stored in secure areas to prevent damage, vandalism, or theft. During construction hours, hazardous materials may be stored temporarily on the ROW but overnight storage on the ROW will be prohibited. All storage containers will remain sealed when not in use and storage areas will be secured (gated, locked, and/or guarded) at night and/or during non - construction periods. Storage Containers: Containers will be compatible with the hazardous materials or wastes stored. If the container leaks or becomes damaged, the substance must be transferred to a container in good condition. Contractor will inspect containers at least weekly to discover any leaks in the containers or the containment systems. Containers used for transportation must comply with the DOT requirements, including those in Title 49, CFR, Part 173. Secondary Containment: Secondary containment will consist of bermed or diked areas that are lined and capable of holding 110 percent of the volume of the stored material plus any potential precipitation accumulation, and will be provided for fuel and oil tanks stored on-site [e.g., in Contractor's yard(s)]. Container Management: Containers holding hazardous substances will be kept closed during transfer and storage, except when it is necessary to add or remove the substance. Incompatible Wastes: Wastes that are incompatible with other wastes will not be placed in the same container, nor in an unwashed container, that previously held an incompatible material. Ignitable or Reactive Substances: Substances that may ignite or are reactive must be located at least 50 feet from the construction yard boundary. "NO SMOKING" signs will be conspicuously placed wherever there is a hazard from ignitable or reactive waste. Examples of ignitable wastes are: paint wastes, certain degreasers, thinners and solvents (petroleum distillates), epoxy resins, and adhesives. Examples of reactive wastes that may be found at construction yards include permanganate and manganese wastes from dry cell batteries. Storm Water: It may be necessary to drain accumulated storm water from within the secondary containment areas that contain the fuel storage tanks. If the storm water has been contaminated, absorbent pads or booms will be used to remove floating petroleum products. After the contamination has been removed, the storm water will be left to evaporate, if possible, otherwise it will be disposed of in an appropriate manner. Prior to disposal, the Environmental Inspector will check for sheen or other evidence of contamination. 3.6.2 Container Labeling Requirements for Hazardous Wastes Contractor will comply with the following labeling requirements for any on-site container (including tanks) used to store accumulated hazardous wastes. The containers will be labeled as required in Title 40 CFR, Part 262 and will contain at least the following information: • chemical name (oil, diesel, etc.), • the accumulation start date and/or the date the 90 -day storage period began; and • the words "Hazardous Waste" and warning words indicating the particular hazards of the waste, such as "flammable", "corrosive", or "reactive." 3.7 DISPOSAL OF HAZARDOUS WASTES Contractor will be responsible for ensuring that all hazardous wastes generated during their operations are collected regularly and disposed of in accordance with all applicable laws. Contractor will determine details on the proper handling and disposal of hazardous waste, and will assign responsibility to specific individuals prior to construction of the project. Hazardous wastes typically include chemicals, spent batteries, and other items. Contractor will ensure that every effort will be made to minimize the production of hazardous waste during the project including, but not limited to, minimizing the amount of hazardous materials needed for the project; using alternative non -hazardous substances when available; recycling usable materials such as paints and batteries to the maximum extent; and filtering and reusing solvents and thinners whenever possible. Any Contractor (generator) producing more than 100 kilograms per month of hazardous waste must apply for an EPA Identification Number. Contractor (generator) producing less than 100 kilograms per month are considered conditionally exempt small quantity generators. A generator can store hazardous wastes on-site for a period of up to 90 days without having to obtain a permit as a storage facility, or as a small quantity generator up to a total of 1000 kilograms. 3.8 CONTAMINATED CONTAINERS Containers that once held hazardous materials as products or which held hazardous wastes must be considered as potential hazardous wastes due to the residues of hazardous contents that may persist. In order for the container to be handled as non -hazardous waste, regulations require that the container be essentially empty and that certain handling requirements for the empty container be followed, including the following: • The containers must be empty, which means as much of the contents as possible have been removed so that none will pour out in any orientation and that they contain less than 1 pound and require special handling because of the waste type. • If the empty containers are less than five gallons, they may be disposed of as non- hazardous solid waste or scrapped. • If the empty containers are greater than five gallons, they must be handled in the following manner: o Returned to the vendor for re -use, o Sent to a drum recycler for reconditioning, or — used or recycled on-site. 3.9 WASTE OIL FILTERS Used, metal canister oil filters can be managed as solid waste as long as they are thoroughly drained of "free flowing" oil (oil exiting drop -by -drop) is not considered "free flowing"); the filters are accumulated, stored, and transferred in a closed, rainproof container. Waste oil filters are best drained by puncturing and gravity draining while the filter is still hot. 3.10 USED LUBRICATING OIL Waste lubrication oil, including contaminated soil and rags, have specific requirements for storage, transportation, and disposal. Contractors are considered "Used Oil Generators" and as such must meet the following requirements: • Have a HAZMAT Plan certified by a registered Professional Engineer and approved by the Company. • Conduct spill prevention briefings frequently enough to assure adequate understanding by all workers. • Label all storage containers "Used Oil". • Ensure storage containers do not have visible leaks 3.11 INSPECTION AND RECORD KEEPING Contractor will inspect all storage facilities on a regular basis, but not less than weekly. The Weekly Hazardous Materials/Wastes Inspection Log in Attachment 2, will be used to record the condition of the facility. In addition to the weekly log, Contractor will maintain records for hazardous materials and hazardous wastes as required by all applicable federal, state, and local regulations and permit conditions. Record keeping requirements include: • hazardous material/waste inspection log • transportation documents • bills of lading • manifests • shipping papers • training records • release report forms • spill history Environmental Inspectors will monitor, inspect, document, and report on Contractor's compliance with all hazardous materials and hazardous waste management practices. 4. POTENTIALLY CONTAMINATED SITES This general procedure is included as a contingency in the event that unexpected or unknown (pre-existing) contaminated sites are encountered during the course of construction. During the course of construction, some potential exists for encountering contaminated soils, groundwater, or other materials. Should such a situation develop where there is a reasonable basis for believing that contaminated materials have been encountered (where contamination is suggested by visible indications or unusual odors), the Contractor will stop work and immediately notify the Environmental Inspector or the Construction Supervisor. The Environmental Inspector or Construction Supervisor will determine next steps, including notification requirements. The Contractor may not commence work without authorization. 5. SPILL CONTROL AND COUNTERMEASURES The measures described in Section 3.0 of this plan are intended to prevent the spill of hazardous materials during normal project construction, operation and maintenance activities. However, not all potential spill situations can be reasonably foreseen or prevented. In accordance with Section 6.1 — Reporting Criteria, the Environmental Inspector will make a note of minor spills and cleanup in their daily logs. These minor spills will be documented in the daily report taken in the event of a major spill. In general, the Contractor will perform all cleanup activities including: (1) specifying in their HAZMAT PLAN specific containment and cleanup procedures; (2) providing necessary materials and labor; and (3) performing all reporting and documentation, as required. Notification and documentation of spills is discussed in greater detail in Section 6.0 of this plan. 5.1 PHYSICAL AND PROCEDURAL RESPONSE MEASURES Physical response actions are intended to ensure that all spills are promptly and thoroughly cleaned up. However, the first priority in responding to any spill is personnel and public safety. Construction personnel will be notified of evacuation procedures, including evacuation routes, to be used in event of a spill emergency. In general, the first person on the scene will: • attempt to identify the source, composition, and hazard of the spill or stain; • isolate and stop the spill and begin clean up of the spill or stain, if possible (i.e., if it is safe). • contain spills or stains, of unknown substances, in a barrel or plastic to prevent migration if rain occurs, • properly store, and • obtain a sample of the unknown substance for laboratory analysis • Notify appropriate personnel and initiate reporting actions; and • Initiate evacuation of the area if necessary. Persons should only attempt to clean up or control a spill if they have received proper training. Untrained individuals will immediately notify the Contractor's primary or alternate emergency coordinators. If there is a spill of an unknown substance and its identity cannot be determined by observing obvious clues (i.e., labels on containers), or observing obvious sources (e.g., hydraulic lines, fuel tanks, etc.), it would not be considered safe for the average person to contain the spill and obtain sample for laboratory analysis. Any spill of an unknown substance should be treated as a hazard and should be approached, contained and sampled by trained emergency response personnel. General construction personnel should be instructed to contain and cleanup spills of only those substances they can safely identify and that can be safely approached (from upwind an upgradient) and handled, after identifying the materials from a safe distance and location. In general, expert advice will be sought to properly clean up major spills (defined as any spill over the reportable quantity for that substance). For spills on land, berms will be constructed to contain the spilled material and prevent migration of hazardous materials or petroleum products toward waterways. Dry materials will not be cleaned up with water or buried. Contaminated soils will be collected using appropriate machinery, stored in suitable containers, and properly disposed of in appropriately designated areas off-site. After contaminated soil is recovered, all machinery utilized will be decontaminated, and recovered soil will be treated as used oil if contaminated with petroleum products or hazardous waste is contaminated with hazardous waste. Contaminated cleanup materials (absorbent pads, etc.) and vegetation will be disposed of in a similar manner. For major spills, cleanup will be verified by sampling and laboratory analysis. If spilled materials reach water, booms and skimmers will be used to contain and remove contaminants. Other actions will be taken as necessary to clean up contaminated waters. In areas where construction activity will cross a small slowing waterbody (25 feet or less), absorbent booms will be placed on the water surface downstream of the construction zone, prior to construction. Clean-up materials including absorbent spill pads and plastic bags will be placed on site at flowing streams and "wet" wetlands when construction is occurring within 100 feet of these areas. For river crossings over 25 feet, cleanup materials will be located on both banks. 5.1.1 On -Site Equipment The following equipment will be maintained on site with each crew using heavy equipment for use in cleanup situations. • shovels • absorbent pads/materials • personal protective gear • fire fighting equipment • medical first-aid supplies • phone list with emergency contact numbers • storage containers • communications equipment 5.2 EMPLOYEE SPILL PREVENTION/RESPONSE TRAINING AND EDUCATION Contractor will provide spill prevention and response training to appropriate construction and inspection personnel. Persons accountable for carrying out the procedures specified herein will be designated prior to construction and informed of their specific duties and responsibilities with respect to environmental compliance and hazardous materials. Contractor is required to maintain a record of those workers who have received training. Note that this training is in addition to the environmental training that will be conducted by the Company. Contractor's training will be provided to inform appropriate personnel of site-specific environmental compliance procedures. At a minimum, this training will include the following: • a review of the Company and Contractor HAZMAT Plan, and discussion of individual responsibilities; • an overview of all regulatory requirements; • methods for the safe handling/storage of hazardous materials and petroleum products; • spill prevention procedures; • operation and location of spill control materials; • inspection procedures for spill containment equipment and materials; • emergency response procedures; • use of personal protective equipment (PPE); • use of spill cleanup equipment; • procedures for coordinating with emergency response teams; • standard information regarding a spill to be provided to Company for agency notification (see Section 6.1); 6. NOTIFICATION AND DOCUMENTATION OF SPILL PROCEDURES Notifications and documentation procedures for all spills that occur during project construction, operation, or maintenance will conform to applicable federal, state, and local laws. Adherence to such procedures will be the top priority once initial safety and spill response actions have been taken. The following sections describe the notification and documentation procedures, and should be implemented in conjunction with the response procedures listed in other sections of this plan. 6.1 REQUIRED NOTIFICATION Notification will begin as soon as possible after discovery of a release. The individual who discovers the spill will contact a Company Construction or Environmental Inspector. If the Environmental Inspector determines that the spill meets the criteria for immediate verbal notification of government agencies (see Section 6.1.3, Reporting Criteria) and/or determines that the spill may threaten human health or the environment, he/she will immediately notify Company's Field Supervisor who will make the required agency notifications as described below. On federal lands, all spills greater than 1 gallon will be reported. Prior to beginning the notification process, the individual initiating notification should obtain as much information as possible to clearly document and communicate the situation. See Section 6.1.1 for standard information that will be requested by agencies. The following mandatory notifications will be made by the Environmental Inspector. • 911 will be called if the spill is deemed to be an emergency • National Response Center (800) 424-8802 (for amounts exceeding the reportable quantity for that material (see section 6.1.3, Reporting Criteria) • Colorado Department of Health and Environment (303) 692-3500 non -emergency (303) 756-4455 emergency • Grand Junction State Patrol/State Hazardous Materials Team, for spill occurring on State Highway rights-of-way (970) 248-7278 • Local Emergency Planning Committee — notified at the following numbers. • Garfield County (Glenwood Springs, CO) (970) 945-9151 6.1.1. Agency Notification When notifying a regulatory agency, the Environmental Inspector will provide the following information: • current threats to human health and safety, including known injuries, if any; spill location (legal land description if available), including landmarks and nearest access route; reporter's name and phone number; time the spill occurred; • type and estimated amount of hazardous materials involved; • potential threat to property and environmental resources, especially waterbodies and wetlands; and • status of response actions. On-site personnel should always consult the Environmental Inspector to clarify regulatory requirements. 6.1.2 Landowner Notification When a spill poses a direct and immediate threat to health and safety and/or property, the landowners potentially affected by the spill will be directly notified by the Company. The Alignment Sheets delineate land ownership along the entire ROW and will be used to determine affected landowners. Immediate notification of landowners is required for all situations in which the spill poses a direct and immediate threat to health and safety and/or property. 6.1.3 Reporting Criteria The Contractor will report to the Company Environmental Inspector all hazardous substance releases regardless of size and petroleum product spills which threaten or enter any waterbody, or that are over 1 quart in size. Verbal reports are required immediately following a major spill when doing so would not delay clean up or administration of urgent medical care. The Company Environmental Inspector will determine if the spill meets the following criteria for immediate agency notification. Any release of hazardous material over the applicable reportable quantities (List of Reportable Quantities), or a petroleum product spill which threatens or enters a waterbody must of reported immediately to the National Response Center (NRC), the BLM, state, and local authorities. On federal lands, all spills greater than 1 gallon will be reported. For petroleum spills over 25 gallons which occur in upland areas notification will be made to the, state, and local authorities.

Agencies that the Company verbally notified of a release will be given written notification by the Company within 30 days. Contractor will provide a written report of all reportable spills requiring agency notification within 24 hours (see Attachment 1). The Contractor will record spill information in a daily log. The following is a list of items that should be included in the daily log (as appropriate, based on the spill incident): • time and date of each log entry; • name of individual recording log entry; • list of all individuals notified, including time and date; • type and amount of material spilled; • resources affected by spill; • list of response actions taken, including relative success; • copies of letters, permits, or other communications received from government agencies throughout the duration of the spill response; • copies of all outgoing correspondence related to the spill; and • photographs of the response effort (and surrounding baseline photographs if relevant). Maintaining detailed and organized records during a spill incident is an important and prudent task. One Contractor representative should be designated to manage the records for an incident. If extensive spill response and cleanup operations are required, the Contractor may choose to assign a bookkeeper to assist in the documentation process. The Contractor's on-site bookkeeper will track and manage all expenditures (i.e., equipment, personnel/labor hours, and associated resources) and will help supplement the information provided in the daily log book.

Where lanes of traffic are reduced or impaired by construction activities, flag persons will be employed. 2.6 SAFE PROCEDURES FOR PREVENTION OF MECHANICAL DAMAGE TO UNDERGROUND FACILITIES The Contractor will give adequate advance notification of all work that will be performed within existing pipeline easements, ROW, or property so that site preparation and supervision can be provided. Before commencing any excavation, the Contractor will receive authorization to commence excavating from the Company Representative. The Company Representative, or his delegate, will locate and stake the centerline and limits of all underground facilities in the area of proposed excavation. The Company Representative will be assigned to monitor all mechanical excavation being carried out within 10 feet of buried or above ground pressurized gas piping. 2.7 DAMAGED PIPE Any dents, gouges, scratches or other similar defects will be brought to the attention of the Company as soon as they are detected. Detrimental defects will not be accepted and will be repaired or cut out of the line as directed by the Company, regardless as to when or how they may have occurred. Grinding to remove defects within dented areas will not be permitted. Gouges, grooves, scratches, or tears may be removed by grinding provided that the wall thickness is not reduced to less than 95 percent of the specified nominal wall thickness. Dents other than those described above will be permitted provided they do not exceed the following maximum levels specified for each case. • As delivered from the pipe mill: maximum depth of 0.5 percent of the pipe diameter and 25 percent of the pipe diameter in any other dimension. • Allowable damage in the field prior to backfill: maximum depth of 1 percent of' the pipe diameter and 50 percent of the pipe diameter in any other dimensions. • Allowable damage in the field after backfill: maximum depth of 2 percent of the pipe diameter and 75 percent for the pipe diameter in any other dimension. Pounding or jacking to remove dents is prohibited. Defects greater than those noted above will be cut out as a cylinder and replaced by welding a pup joint to the line. 2.8 HIGH VOLTAGE HAZARD AND MITIGATION OF INDUCED VOLTAGE EFFECTS Generally work will be stopped if one or more of the following conditions prevail: • during local electrical storms denoted by visible lightning or the sound of thunder; during high winds, wet snow, or freezing rain; 2.9 COLD WEATHER CONSTRUCTION The Contractor will be aware of the special considerations that must be made with respect to cold weather construction including exposure, hypothermia, frostbite, heavy clothing, and adverse driving conditions and will account for these in the completion of the work in order to eliminate personal injury and property damage.

Report on the Class I Cultural Resource Inventory for a Sensitive Area Study on Private Lands for the Proposed Rulison to Enterprise Pipeline in Garfield County, Colorado, for ETC Canyon Pipeline GRI Project No. 2828 24 April 2008 Prepared by Carl E. Conner (Principal Investigator) and Barbara Davenport Grand River Institute P.O. Box 3543 Grand Junction, Colorado 81502 State of Colorado Antiquities Permit No. 2008-63 Submitted to Board of County Commissioners Garfield County, Colorado Abstract At the request of ETC Canyon Pipeline (as represented by WestWater Engineering), Grand River Institute conducted a Class I cultural resources inventory for a Sensitive Area Study in relation to an anticipated Special Use Permit Application with Garfield County for the proposed Rulison to Enterprise Pipeline project. The study is for a linear route of 10.2 miles that is located between Parachute and Rulison, which, except for about two miles on the east end where it tums south, is located north of the Colorado River and I-70. The Class I inventory was undertaken to ensure the project's compliance with county, state, and federal laws and regulations goveming the identification and protection of cultural resources on privately owned lands that will be affected by a government action. This work was performed under State of Colorado Antiquities Permit No. 2008-63. The purpose of the cultural resources investigation was to identify previously recorded resources within or near the project area that may be adversely affected by the proposed action and to evaluate the potential of additional such resources in the project area. The Class I files search and report preparation were performed during April 2008. The pipeline will be used to transport natural gas to an existing pipeline infrastructure owned by Enterprise Pipeline. The pipeline will be placed in an existing Right -of -Way (ROW) adjacent to pipelines owned by Williams Production RMT. Surface disturbance will occur in a 30 -foot permanent ROW and a 30 -foot temporary ROW, as well as three 2 -acre staging areas. Although sites occur near the project area, no significant resources (eligible to the National Register of Historic Places) have been recorded within 100 meters of the proposed pipeline. Accordingly, a determination of "no effect" for the project is recommended pursuant to Section 106 of the National Historic Preservation Act (36 CFR 800). Of concern, however, is site 5GF1135 that is classified as "not eligible—officially" and by estimation lies about 200 feet south of the proposed pipeline. Despite its evaluation, it is apparently a EuroAmerican grave and as such is protected under the Colorado Revised Statute of Historical, Prehistorical and Archaeological Resources, Unmarked Human Graves [Section 1, 24-80-401 (1), 1988 Ret. Vol., as amended]. The grave's location should be verified by an archaeologist, clearly marked, and avoided by any construction. ii Table of Contents Introduction 1 Location of the Project Area 1 Environment 1 Figures 1-3.

A.1 iii Introduction At the request of ETC Canyon Pipeline (as represented by WestWater Engineering), Grand River Institute conducted a Class I cultural resources inventory for a Sensitive Area Study in relation to an anticipated Special Use Permit Application with Garfield County for the proposed Rulison to Enterprise Pipeline project. The study is for a linear route of 10.2 miles that is located between Parachute and Rulison, which, except for about two miles on the east end where it turns south, is located north of the Colorado River and I-70. This work was performed under State of Colorado Antiquities Permit No. 2008-62. Carl E. Conner, Principal Investigator, was assisted by archaeologist Barbara J. Davenport. The Class I files search and report preparation were performed during the first two weeks of April 2008. The Class I inventory was undertaken to ensure the project's compliance with state and federal legislation governing the identification and protection of cultural resources on privately owned lands that will be affected by a government action. It was done to meet requirements of the National Historic Preservation Act (as amended in 1992), the National Environmental Policy Act of 1969 (42 U.S.C. 4321), the Federal Land Policy and Management Act of 1976 (43 U.S.C. 1701), and the Archaeological Resources Protection Act of 1979 (16 U.S.C. 470aa et seq., as amended), and Article 80.1, Colorado Revised Statutes. These laws are concerned with the identification, evaluation, and protection of fragile, non- renewable evidence of human activity, occupation, and endeavor reflected in districts, sites, structures, artifacts, objects, ruins, works of art, architecture, and natural features that were of importance in human events. Such resources tend to be localized and highly sensitive to disturbance. All work was performed according to guidelines set forth by the Office of Archaeology and Historic Preservation (OAHP) of the Colorado Historical Society. Location of the Project Area The proposed pipeline is located on private lands that lie between the town of Parachute, Colorado, and Holms Mesa to the south of Rulison. It lies in T. 6 S., R. 95 W., Sections 25, 26, 32, 33, 34, 35, and 36; T. 7 S., R. 95 W., Sections 1, 5, and 6; T. 7 S., R. 96 W., Sections 1 and 2; 6th P.M. (Figure I) Environment The project area is within the Piceance Creek Basin, one of the major geologic subdivisions of Colorado. The Piceance Creek Basin is an elongate structural downwarp of the Colorado Plateau province that apparently began its subsidence approximately 70 million years ago during the Laramide Orogeny. Sediments from surrounding highlands were deposited in the basin, accumulating to a thickness of as much as 9000 feet by the lower Eocene epoch, when subsidence ceased. Regional uplift occurred in the Late Tertiary, and 1 L. R. 9511. R; 9615.= a: CJZ '?❑ N O4. t--: $ acG � 0 d• 0 d,7)40N 2 ° y O F1.

The Wasatch formation underlies the study area. It consists of a series of interbedded variegated mudstones, sandstones, and siltstones of varying colors --brick red, tan, white, and purple. Forming after a period of erosion, the Wasatch is the first extensive continental deposit following those of the Cretaceous -age Mesaverde Group. Sediments are stream, floodplain, and swamp deposits. In the west 1.0 mile portion of the study area, Quaternary gravel deposits overlay the Wasatch formation. The project area rests on benchland. Elevations range from about 5120 to 6220 feet. This relatively low elevation is host to a cool semiarid climate where temperatures can drop to -10 degrees F during the winter and summer temperatures may reach 100 degrees F; there is a maximum of 120 frost free days and the annual precipitation is about 12 inches. The surrounding higher elevations are characterized as cooler and moister. Annually, the high mountain temperatures could average 5 degrees cooler and the precipitation as much as 14 inches greater than the surrounding low elevations (USDA 1978:244). There are several generalized vegetation communities in the area including riparian along the river, big sage and saltbush shrubland in the valley bottom, and juniper/oak woodland on the surrounding mountain slopes. However, the prehistoric streamflow and habitats along the Colorado River have been significantly altered by historic EuroAmerican water diversions, reservoirs, and irrigation of agricultural fields. The valley bottom has also changed due to infringement by pipelines, gravel operations, roadways and bridges. Ground visibility ranges from 20% in the relatively undisturbed areas to about 90% along the roads and pipelines. These communities support a variety of wildlife species. Mule deer, elk, coyote, and black bear are common, as are cottontail rabbits, and various rodents. Mountain lion, bobcat, fox, skunk, badger, and weasel are also likely inhabitants. Bird species observed in the area include the wild turkey, jay, raven, red -shafted flicker, long-eared owl, and various raptors. Although the present day land use of the project area (including energy development, grazing, ranching and farming) has pushed some of the large mammals into the surrounding mountains, deer and wild turkeys make heavy use of the cultivated fields during the months of colder temperatures. Paleoclimate Relatively small changes in past climatic conditions altered the exploitative potential of an area and put stress upon aboriginal cultures by requiring adjustments in their subsistence patterns. Therefore, reconstruction of paleoenvironmental conditions is essential to the understanding of population movement and cultural change in prehistoric times (Euler et al. 1979). To interpret whatever changes are seen in the archaeological record, an account of fluctuations in past climatic conditions must be available or inferences must be made from 5 studies done in surrounding area. Generally, only gross climatic trends have been established for western North America prior to 2000 BP (Antevs 1955; Berry and Berry 1986; Mehringer 1967; Madsen 1982; Wendlund and Bryson 1974; Peterson 1981). Scientific data derived from investigations of prehistoric cultures and geoclimatic and bioclimatic conditions on the southem Colorado Plateau over the past two millennia have achieved a much greater degree of resolution (Dean et al. 1985). Files Search Results Cultural resource investigations in the region have yielded surface diagnostic artifacts and excavated cultural materials consistent with the regional cultural history. Evidence provided by chronometric diagnostic artifacts and radiocarbon analyses indicate regional occupation during the Paleoindian Era, Archaic Era, Formative Era, and Protohistoric Era. Historic records suggest occupation or use of the region by EuroAmerican trappers, settlers, miners, and ranchers as well. Overviews of the prehistory and history of the region are provided in documents published by the Colorado Council of Professional Archaeologists entitled Colorado Prehistory: A Context for the Northern Colorado Plateau (Reed and Metcalf 1999), and by the Colorado Historical Society entitled Colorado Plateau Country Historic Context (Husband 1984). A file search for known cultural resources within the project area was made through the Colorado Historical Society's Office of Archaeology and Historic Preservation. This review identified thirty-six reports that have been done in the general area, which are listed in Table A-1 (Appendix A). The files search identified fifty-nine sites that occur within about 0.5 mile of the study area (Table A-2). No significant cultural resources (designated eligible for listing on the National Register of Historic Places) occur within 100 meters of the proposed pipeline. One prehistoric open camp (5GF1136) and one isolated find (5GF1146) — both evaluated as not eligible by the State Historic Preservation Officer— occur within 100 feet of the proposed pipeline. Site 5GF1135, a human burial also classified as not eligible—officially, lies about 200 feet south of the proposed pipeline. Archaeological Assessment of Prehistoric Cultural Resources Previous archaeological studies in the general vicinity have suggested regional occupation for as long as 8000 years, although recently an inventory of block units east of this study area within the Doghead GAP (Conner et al. 2006) provided direct evidence of the presence of Foothill -Mountain Paleoindian occupation at 5GF1323, which pushes the regional prehistoric occupation dates back to about 10,000 yr BP. Historic records also indicate a permanent Euro -American presence in the region began as early as the late 1880's. Notably, the prehistoric sites in the river corridor have been impacted by the 130 year occupation and use of the area by EuroAmericans. Notably, many of the newly and 6 previously recorded resources in the general area indicate it was intensively occupied during the Protohistoric Era. Unfortunately for many of the sites where wickiups were present, post - cutting and wood collection by the Historic EuroAmerican settlers and ranchers over the past 125 years has nearly wiped out evidence of their presence. Also, surface collection of diagnostic artifacts has impacted the sites and affected the assignment of cultural/temporal associations. In general, although the study area was probably not continuously occupied prehistorically, it seems to have offered an attractive environment for gathering, floral processing, hunting, as well as lithic procurement and processing. Site density in the surrounding mesa areas is high, probably due to two factors: good access to permanent water, and strategic topographical positioning on the ridge tops and open benches. Such camp placement provided a good view of the surrounding lower elevations for purposes of hunting and protection. The heavily vegetated canyon bottoms were accessed for reasons of acquiring water and for the procurement of floral and faunal resources. The apparent differences in the characteristics of the upland and lowland sites may be due to factors other than cultural selection. The lowland sites are subjected to more artifact collecting than the uplands, and the areas along the Colorado River have been subject to few cultural resource surveys. The upland area exhibits a very thick vegetation cover that may be limiting discovery of features and additional artifacts. Lowland sites exhibit greater variability in site types. While the uplands are limited to isolated finds, open camps, and lithic scatters; the lowlands contain these site types and open architectural sites, sheltered sites, and a single tool stone procurement area. The lowland sites contain higher frequencies of cultural features or evidence of features. These features include fire -cracked rock scatters, charcoal stains, hearths, stone structures, and wickiups. All of the prehistoric sites contain low numbers of artifacts, including very limited numbers of debitage, bifacial tools and expedient tools. This suggests conservation, curation, and reuse of flaked stone tools in an area where tool material sources are limited. Lowland sites tend to be situated in the pinyon -juniper vegetation community in greater frequencies than is suggested by the relative proportion of the pinyon juniper to other vegetation communities. The sites in the uplands are distributed proportionally to the size of the vegetation communities, with the mountain shrub and sagebrush communities exhibiting the highest site density. Too little is known of the age of the sites to make any definitive statements. The distribution of site ages based on projectile points and ceramics is generally the same as portrayed in Reed and Metcalf (1999), but the lack of absolute dating precludes any conclusions in this area. Lithic scatters exhibit a smaller site size than open camps in both the lowland and upland settings. Isolated finds are distributed across a wider range of slopes than lithic scatters or open camps. 7 The differences in the type and distribution of historic sites are: Sites in the uplands are limited to sheep and cattle raising activities and are primarily post -1889. Sites in the uplands are distributed proportionally to the size of the vegetation communities, with the mountain shrub and sagebrush communities exhibiting the highest site density. Sites in the lowlands display a greater diversity in types and are found mainly in the pinyon juniper and sagebrush zones. The historic sites in the lowlands are concentrated near transportation corridors and near permanent water sources, particularly the habitation sites. Sites indicative of particular economic activities are spread across the landscape. During 1980, the BLM 's Glenwood Springs Resource Area was subject to an archaeological survey that randomly sampled three percent of its managed lands. A total of 17,400 acres was surveyed for cultural resources. As a result, 58 prehistoric sites and 2 historic sites were recorded, an average of about 2 sites per section (.0034/acre). Three types of prehistoric sites were distinguished by the study; limited activity areas, short-term camps, and large habitation sites. These were classified on the basis of site size and the diversity of artifacts/activities represented. Notably, the sites were unevenly distributed and varied by vegetation community. The highest site density, about 5.0 sites/section (.0078/acre), occurred in pinyon/juniper and sagebrush communities. Concurrently, the greatest number of sites located during the survey tended to occur in or near the pinyon/juniper community. Other environmental factors found to be important during the statistical analysis of the settlement patterns included 1) vertical distance between the site and the primary water source is a greater controlling factor than the horizontal distance, 2) sites tend to be near or on points of vantage, 3) sites tend to be located in forested areas, preferably with a southern exposure and, 4) sites tend to occur on flat ground (less than 40% grade) in areas of relatively low surface relief (Burgess et al. 1980:108-120, 138-139). In general, the region exhibits a relatively low site density and sites tend to cluster near permanent water sources. Relevant Historical Background post -1880 The Ute people occupied large areas of Western Colorado until about 1881. Due to the White River Ute's discontent that led to the "Meeker Massacre," as the incident became known, a congressional investigation led to the Treaty of 1880 that stipulated the removal of the White River bands to the Uintah Reservation in northeastern Utah. The Uncompahgre band was to be given a small reservation in the vicinity of the confluence of the Colorado and Gunnison Rivers. Aware of the value of these agricultural lands, however, the commission charged with enforcing the terms of the treaty, under the direction of Otto Mears, manipulated the location process using a loophole in the treaty language, and the Uncompahgres were given lands in Utah near the Uintah Reservation. The Southern Ute bands were left on the small reservation in southwestern Colorado that had been given them by the Treaty of 1873. On 1 September 1881, the last of the Utes were moved to their new reservations in Utah, and western Colorado was completely opened to the whites. 8 Interest in the potential agricultural lands of western Colorado (namely the Uncompahgre, Gunnison, Colorado, Dolores, San Miguel, White, and La Plata River valleys) had been growing for some time prior to the Utes' banishment, and by the spring of 1881 frontier towns closest to the Ute lands were "crowded with people, anxious to enter the Reservation and take possession of the most desirable locations (Haskell 1886:2)." Only days after the last of the Utes had been expelled, settlers began rushing onto the reservation lands. Settlement activity spread quickly --during the autumn months of 1881 land claims were staked, townsites were chosen, and railroad routes were surveyed (Haskell 1886, Borland 1952, Rait 1932). However, because the former reservation lands were not officially declared public lands until August 1882, the first year of settlement activity was marked by a degree of uncertainty regarding the legality of land claims. When finally announced, the 1882 declaration did not allow homestead entries on the newly opened lands, but only pre- emptions, or cash entries, at the rate of $1.25 per acre for agricultural land, $5.00 per acre for mineral land (Borland 1952:75). By 1895, the major portion of the land along the River and its tributaries had been claimed, mostly under Cash Entry patents. The settlers raised their own food and availed themselves of the plentiful game in the area. Gardens, hay fields, and orchards were planted, and irrigation ditches were dug to divert the creek's water to cultivated fields. Large herds of cattle and sheep were accumulating, grazing the valley floor and the vast open range above, driven to the uplands via trails leading up the various gulches. Because the area was still fairly remote, competition for lands had not yet begun. Travel in and out of the Rifle area was restricted to horse and/or wagon. There were several well-developed Ute trails, and in the early 1880s, the federal government had built the aforementioned road between the White and Grand Valleys. In 1885, a toll road opened along the Grand River between Rifle and Grand Junction; prior to the building of this road through DeBeque Canyon, the route to Grand Junction had been a two-week journey "through the Cedar Hills, up Kimball Creek...down the "Sawtooth Range to Fruita and then back to Grand Junction" (Murray 1973:5). But, despite this network of trails and roads, Parachute remained pretty much isolated. With the coming of the D&RG railroad in 1890, however, new pressures were brought to the area. More and more settlers arrived, competing not only for arable land but also for grazing privileges on the unpatented public domain of the surrounding uplands. Increasing numbers of cattle and sheep were imported, some being run as commission cattle for outside investors (ibid:84). Open warfare between cattle and sheep ranchers ensued, resulting in the slaughter of thousands of animals. Four thousand sheep belonging to Messrs. Starkey and Charlie Brown were killed by masked men who tried to drive the animals over cliffs at the head of a Clear Creek tributary and above the Granlee Schoolhouse (LaPoint et al. 1981:3-51). Another 4000 sheep belonging to J.B. Hurlburt were driven to their deaths above Ben Good Creek, a tributary of East Fork. The animosity between cattlemen and sheepmen continued into the 1900s. Finally, Congress passed the Taylor Grazing Act in 9 1934, bringing to an end to the free range by providing for regulated grazing and an end to the Sheep -Cattle Wars. Cash Entry, Desert Land, and Homestead patents continued to be granted into the 1920s and 30s. Ranching and farming were still the most important economic activities in the Parachute area and remained so until the 1960s and 1970s when many of the farms and ranches of the region were bought up by large companies interested in the large-scale extraction of oil shale and natural gas. Summary and Recommendations The National Historic Preservation Act of 1966 (NHPA) directs that federal agencies protect cultural resources that possess significant values. Significance is a quality of cultural resource properties that qualifies them for inclusion in the NRHP. The statements of significance included in this report are field assessments that support management recommendations to the State Historic Preservation Officer (SHPO). The final determination of site significance is made by the controlling agency in consultation with the SHPO. The Code of Federal Regulations was used as a guide for site evaluations. Titles 36 CFR 50, 36 CFR 800, and 36 CFR 64 are concerned with the concepts of significance and (possible) historic value of cultural resources. Titles 36 CFR 65 and 36 CFR 66 provide standards for the conduct of significant and scientific data recovery activities. Finally, Title 36 CFR 60.6 establishes the measure of significance that is critical to the determination of a site's NRHP eligibility, which is used to assess a site's research potential: The quality of significance in American history, architecture, archaeology, and culture is present in districts, sites, buildings, structures, and objects of State and local importance that possess integrity of location, design, setting, materials, workmanship, feeling, and association, and a) that are associated with events that have made a significant contribution to the broad patterns of history; or b) that are associated with the lives of persons significant in our past; or c) that embody the distinctive characteristics of a type, period, or method of construction, or that represent the work of a master, or that possess high artistic values, or that represent a significant and distinguishable entity whose components may lack individual distinction; or d) that have yielded, or may be likely to yield, information important in the prehistory or history. The eligibility determination and consultation process is guided by Section 106 of the NHPA (36 CFR 60, 63, and 800). Final determinations of National Register eligibility and effect are made by the controlling agencies in consultation with the State Historic Preservation Officer. The Class 1 files search and report preparation were performed during April 2008. The pipeline will be used to transport natural gas to an existing pipeline infrastructure owned 10 by Enterprise Pipeline. The pipeline will be placed in an existing Right -of -Way (ROW) adjacent to pipelines owned by Williams Production RMT. Surface disturbance will occur in a 30 -foot permanent ROW and a 30 -foot temporary ROW, as well as three 2 -acre staging areas. Although sites occur near the project area, no significant resources (eligible to the National Register of Historic Places) have been recorded within 100 meters of the proposed pipeline. Accordingly, a determination of "no effect" for the project is recommended pursuant to Section 106 of the National Historic Preservation Act (36 CFR 800). Of concern, however, is site 5GF1135 that is classified as "not eligible—officially" and by estimation lies about 200 feet south of the proposed pipeline. Despite its evaluation, it is apparently a EuroAmerican grave and as such is protected under the Colorado Revised Statute of Historical, Prehistorical and Archaeological Resources, Unmarked Human Graves [Section 1, 24-80-401 (1), 1988 Ret. Vol., as amended]. The grave's location should be verified by an archaeologist, clearly marked, and avoided by any construction. References Antevs, E. 1955 Geologic -climate dating in the west.

Date: 06/28/2007 Contractor: Grand River Institute A.9 INTEGRATED VEGETATION AND NOXIOUS WEED MANAGEMENT PLAN RULISON TO ENTERPRISE PIPELINE GARFIELD COUNTY, COLORADO Prepared For: ETC Canyon Pipeline Prepared by: WestWater Engineering 2570 Foresight Circle #1 Grand Junction, CO 81505 In coordination with: Wagon Wheel Consulting 111 E. 3rd St. Ste 213 Rifle, CO 81650 April 2008 1.0 INTRODUCTION 1.1 Project Description ETC Canyon Pipeline has requested WestWater Engineering (W WE) in coordination with Wagon Wheel Consulting to provide an "Integrated Vegetation and Noxious Weed Management Plan" for a proposed "special use permit" in Garfield County, Colorado. ETC Canyon Pipeline is seeking the special use permit to install a 24 -inch gas pipeline from Holms Mesa to an existing interconnect approximately 2 miles north of Parachute, Colorado. The total length of the pipeline is 10.4 miles. The pipeline will be used to transport natural gas to an existing pipeline infrastructure owned by Enterprise Pipeline. The pipeline will be placed in an existing Right -of —Way (ROW) adjacent to pipelines owned by Williams Production RMT. Surface disturbance will occur in a 30 -foot permanent ROW and a 30 -foot temporary ROW, as well as three 2 -acre staging areas. The proposed pipeline is located on private lands that lie between the town of Parachute, Colorado, and Holms Mesa to the south of Rulison (Figure 1). The proposed pipeline begins at the gas plant approximately two miles north of Parachute, travels south for about 150 meters, and then follows an existing pipeline ROW in an easterly path crossing County Road 215 and ascending a steep hillside to the mesa immediately east of the county road. The pipeline then proceeds southeast where it parallels Interstate 70 eastward toward Rulison, Colorado. The pipeline alignment turns southeast crossing I-70, the frontage road south of I-70, the railroad, and a small power line before crossing the Colorado River. From the Colorado River the pipeline heads south along the edge of an irrigated alfalfa field, crosses County Road 309, then continues south to its terminus on Holms mesa. The topography along the pipeline route varies from flat irrigated meadows and hay fields to steep rocky sections with piton -juniper (PJ) and oakbrush. The pipeline also crosses the Colorado River and a series of wetlands located in an overflow channel to the south of the river. Elevations along the pipeline route range from 5,146 feet near the Colorado River to 6,427 feet on Holms Mesa. Numerous natural gas well pads are adjacent to the pipeline alignment. Rural residences are widely spaced in the vicinity of the proposed pipeline alignment along County Road 309 and the Holms Mesa area. The primary use of the surrounding area of the pipeline is agriculture/ rangeland, wildlife habitat and recent natural gas extraction/development. 2.0 LANDSCAPE SETTING 2.1 Vegetation Communities Vegetation communities along the pipeline route are categorized as PJ woodlands and mixed sagebrush and greasewood shrublands. PJ woodlands are dominated by pinon pine (Pinus edulis) and Utah juniper (Juniperus utahensis) mixed with an understory of mainly Wyoming sagebrush (Artemesia tridentata wyomingensis), forbs, and grasses. Numerous ephemeral washes bisect the alignment in the section that parallels Interstate 70, most often in a north to south flow pattern. Vegetation along the washes consists of greasewood (Sarcobatus vermiculatus), rabbitbrush (Chrysothamnus nauseosus), basin big sagebrush (Atermesia tridentata tridentata), and scattered four -winged saltbush (Atriplex canescens). The shrublands WestWater Engineering Page 1 of 18 4/9/2008 i §\wAcgy §� j/ 1- > o )0§ 50 ° / $ 2 a 2 > • v c K -J Weed Locations e within the project area are composed primarily of Wyoming big sagebrush, greasewood, and rabbitbrush (Chrysothamnus viscidiflorus). Non-native downy brome (Bromus tectorum) dominates the understory for this shrubland community as well as the PJ woodlands on and adjacent to Holms Mesa. Agricultural lands within the pipeline corridor include pasture land located southeast of the gas plants near County Road 215, pasture land located north of the Colorado River near Rulison, irrigated alfalfa fields south of the Colorado River near Rulison, and irrigated meadows on the alignment on Holms Mesa. The pipeline also crosses through riparian and wetlands habitat found adjacent to the Colorado River. The vegetation in this area is composed primarily of Fremont cottonwoods (Populus fremontii), sumac (Rhus trilobata), Woods' rose (Rosa woodsii), and tamarisk (Tamarix ramosissima). 2.2 Soil Types The east terminus of the proposed pipeline sits atop Holms Mesa, primarily on Vale silt loam, 6 — 12% slopes. Native vegetation characteristic of Vale silt loam is Western wheatgrass (Pascopyrum smithii), prairie sandreed (Calamovilfa longifolia), needle and thread grass (Hesperostipa comata), rabbitbrush (Chrysothamnus nauseosus), and Utah serviceberry (Amelanchier utahensis). The pipeline will run north and descend very steep (up to 70%) slopes of Torriorthents and rock outcrop whose native characteristic vegetation is wheatgrass (Agropyron sp.), bluegrass (Poa sp.), Indian ricegrass (Oryzopsis hymenoides), Wyoming big sagebrush, (Artemesia wyomingensis), pinon (Pinus edulis), and Utah juniper (Juniperus utahensis). As the pipeline continues north it descends the less steep flank of Holms Mesa consisting of Potts loam and Ildefonso stony loam, 12 — 45% slopes. Native vegetation found on this soil complex includes wheatgrass, needle and thread grass, Indian ricegrass, Utah serviceberry, piiion, and Utah juniper. Soils encountered as the pipeline crosses the Colorado River are Arvada loam, Torrifluvents, and Heldt clay loam. The soils in the riparian area are nearly level, have high water tables, and can be periodically flooded. Characteristic native vegetation of this soil complex are water tolerant grasses, sedges, rushes, greasewood, and cottonwood. The pipeline then runs westward, north of I-70, on primarily only one soil, Arvada loam, 1 — 6% slopes. Characteristic native vegetation species include; western wheatgrass, alkali sacaton (Sporobolus airoides), inland saltgrass (Distichlis spicata), winterfat (Krascheninnikovia lanata), and greasewood. The pipeline route then ascends a hilly area generally consisting of Potts loam and Ildefonso stony loam, 3 — 12 % slopes. The descent into the Parachute Creek drainage crosses a short very steep area of badland, sparsely covered with Utah juniper and shrubs. The soils of the western terminus, near Parachute Creek, are primarily Heldt clay loam and Nihill channery loam on 1 - 6% slopes. The characteristic native vegetation of those soils are western wheatgrass, needle and thread grass, rabbitbrush, and basin big sagebrush (Artemesia tridentata tridentata). 3.0 NOXIOUS WEEDS Noxious weeds are plants that are not native to an area. Most have come from Europe or Asia, either accidentally or as ornamentals that have escaped. Once established in a new environment they tend to spread quickly since insects, diseases, and animals that normally control them are WestWater Engineering Page 3 of 18 4/9/2008 absent. Noxious weeds are spread by man, animals, water, and wind. Prime locations for the establishment of noxious weeds include roadsides, sites cleared for construction, areas that are overused by animals or humans, wetlands, and riparian corridors. Subsequent to soil disturbances, vegetation communities can be susceptible to infestations of invasive or exotic weed species. Vegetation removal and soil disturbance during construction can create optimal conditions for the establishment of invasive, non-native species. Construction equipment traveling from weed -infested areas into weed -free areas can disperse noxious or invasive weed seeds and propagates, resulting in the establishment of these weeds in previously weed -free areas (Photo 1). Photo 1. Potential weed vector — accumulated soil on equipment The Colorado Noxious Weed Act Colorado (8 CCR 1203-19) requires local governing bodies to develop noxious weed management plans (State of Colorado 2005). Both the State of Colorado and Garfield County maintain a list of plants that are considered to be noxious weeds. The State of Colorado noxious weed list includes three categories. List A species must be eradicated whenever detected (none were found). List B species include weeds whose spread should be halted (7 species found). List C species are widespread, but the State will assist local jurisdictions which choose to manage those weeds (3 species found). The Garfield County Weed Advisory Board has compiled a list of 21 plants from the State list considered to be noxious weeds within the county (see Appendix A). Six of those weed species were found in, or near, the project area. The Garfield County Weed Advisory Board has duties to: 1) develop a noxious weed list; 2) develop a weed management plan for designated noxious weeds; and WestWater Engineering Page 4 of 18 4/9/2008 3) recommend to the Board of County Commissioners (BOCC) that identified landowners submit an integrated weed management plan for their properties. 3.1 Survey Methods Mapped soil types, as published by the Natural Resources Conservation Service (NRCS), U.S. Department of Agriculture (USDA), were reviewed to determine the soil types and vegetation characteristics of the plant site and surrounding property (NRCS 2008). A field inspection of the proposed Rulison - Enterprise pipeline route was conducted by WWE biologists on March 24 and 25, 2008. WWE biologists surveyed an area 150 feet from the center line on both sides of the proposed pipeline to identify vegetation communities and to search for, identify, and map noxious weed species. A snow cover of 12-24 inches prevented accurate detection and identification of existing weeds on the north flank of Holms Mesa. Only those plants persisting above the snow were observed and recorded. The remainder of the survey area was free of snow. Vegetation types were determined through field identification of plants, aerial photography, and on -the -ground assessments of plant abundance visible during the survey. Identification of plant species was aided by using pertinent published field guides (Whitson et al. 2001, CWMA 2007, Kershaw et al. 1998). Weeds visible above the snows were identified from dried residual growth. Photographs were taken of the general project location, vegetation and terrain, and other specific biological findings. Locations of weeds and other features included in this report were recorded with the aid of a handheld global positioning system instrument (GPS) using NAD83/WGS84 map datum, with all coordinate locations based on the Universal Transverse Mercator (UTM) coordinate system in Zones 12S and 13S (Appendix B). 3.2 Observations The most prevalent listed weeds were Scotch thistle, tamarisk, redstem filaree, and cheatgrass (Photos 2 and 3). Other problematic, but not listed, weeds noted during the survey were kochia and Russian thistle. Kochia and Russian thistle were found scattered in some disturbed areas, but a high concentration of kochia was found in a silted -in pond at UTM 12S 757183mE 4374161mN (Appendix C, Photo 5). See Table 1 for the general location of listed weeds. Specific UTM coordinates of weeds can be found in Appendix B. 3.3 Treatment and Control of Noxious Weed Infestations Invasive and noxious weeds commonly occur along creek corridors and adjacent drainages, especially along riparian areas, pipeline routes, disturbed areas such as well pads, roadsides, and abandoned fields. Six weed species from the Garfield County list were found in or near the proposed pipeline ROW and are indicated by bold type in Table 2. Included in Table 2 are weed life cycle type, state listing category, and recommended control method for each weed species. Those in regular type were also observed during the survey and are listed by the State of Colorado as noted (CWMA 2007). The locations of these weeds were plotted on the project map (Figure 1).

Observed Noxious Weed Locations in the Project Area Common Name* Scientific Name USDA Symbol General Location and Comments Bull ThistleB Cirsium vulgare CIVU Very few scattered plants along or near the Colorado River. Common Mulleins Verbascum thapsus VETH A few patches in disturbed sites along benches on the north slope of Holms Mesa. Much heavier concentrations along the Colorado River. Downy Bromes Bromus tectorum BRTE Also known as cheatgrass. Can be found scattered throughout much of the project area, especially in the valley bottom. There is less downy brome in the juniper along the north slope of Holms Mesa. Halogetons Halogeton glomeratus HAGL Scattered very thinly along the valley bottom pipeline route. There are a few small concentrations where the pipeline route runs north of I-70. Houndstongue° Cynoglossum officinale CYOF Only one patch of about 6 plants along a ditch at the north base of Holms Mesa. Plumeless Thistle Carduus acanthoides CAAC Two small patches separated by about 50 feet an the flank of Holms Mesa (Appendix C, Photo 9). The northem patch is in a small moist area in juniper and contains about 30 plants. The southern patch was obscured by snow but at least 6 rosettes were seen in a disturbed opening (probably an old roadbed) in the juniper stand. Redstem FilareeB Erodium cicutarium ERCI6 Thickly scattered throughout the pipeline route and extending beyond 150 feet on either side. Can be found primarily in the valley bottoms of the Parachute Creek and Colorado River drainages and on top of Holms Mesa. Not found directly in recently plowed/mulched portions of the route but was found immediately on either side of those portions of the route (Appendix C, Photo 6 and 7). Russian Olive° Elaeagnus angustifolia ELAN A cluster of 5 trees along the Colorado River. Scotch Thistle° Onopordum acantbiune ONAC About 500 plants directly in the pipeline route along a swath 1000 feet long by 50 feet wide. Almost all are 2"d year rosettes which means that they will bloom and spread seed this season. Only one first year rosette was seen but they probably have only begun to sprout from last year's seed (Appendix C, Photo 8). Tamarisk° Tamarix sp. TARA Also called Salt Cedar. Common along the Colorado River, near the mouth of drainages, and along one silted -in pond. A few tamarisks were also found along a gully on the northwest flank of Holms Mesa (Appendix C, Photo 10). * Govemment weed listing: Bold - Garfield County, Colorado.

Weed Control Methods Common Name* Scientific Name USDA Symbol Type** Control Methods Bull Thistle° Cirsium vulgare CIVU B/A Tilling or, because of the small number of plants, hand grubbing in the rosette stage. Mow at bolting or early flowering; Cut and bag mature seed heads. Herbicides in rosette stage. Common Mullein` Verbascum thapsus VETH B Cut and dig rosettes and bolting plants, re -seed with aggressive grasses. Herbicides if necessary. Downy Brome` Bromus tectorum BATE A Eliminate seed source; re -vegetate with native grasses; herbicide treatment in earlyspringand fall. Halogeton Halogeton glomerattrs HALL A Planting competitive salt tolerant perennials or grasses can be very effective. Susceptible to herbicides in the pre -flowering stage. Avoid high intensity grazing in early Spring as this has been shown to significantly increase halogeton (Pavek 1992). Houndstongue Cynoglossum officinale CYOF B Re -seed with aggressive grasses, remove at flowering or early seed, dig or grub at pre -bud or rosette stage or apply herbicides prior to bud stage. Plumeless Thistle Carduus acantboides CAAC B/WA Tillage or, because of the small number of plants, hand grubbing to sever the tap root below a 2 inch depth. Herbicides in rosette or early bolting stage. Biological control with insects is not practical on this small infestation. Redstem Filaree ° Erodium cicutariurn ERCI6 B/A Early Spring tillage before weed emergence in the existing corridor to a depth of 5 -10 cm. Tillage is not practical in the thick greasewood or sagebrush land bordering the corridor. Herbicide application in Spring while plants are small. Thick infestations adjacent to the pipeline route mean that control of this weed will be an ongoing task for many years (Trainor and Bussan 2001). Russian Olive° Elaeagnus angustifolia ELAN p Herbicide on cut stumps or on the cut surfaces after girdling (Colorado State Parks 2005). Scotch Thistle Onopordum acanthium ONAC B Tillage, hand grubbing; herbicides in rosette stage; mow at bolting stage. Tamarisk° Tamarix sp. TARA p Repeated flooding prevents seedling establishment. Herbicide treatment on basal portion of young plants; cut larger plants and treat with herbicide plus adjuvant within 30 minutes. Plant area with native species to shade out tamarisk. Biological with Diorhabda elongata deserticola, the tamarisk leaf beetle, if available (Tamarisk Coalition 2007). * Government weed listing: Bold - Garfield County, Colorado. Superscript - Colorado State B or C list. ** Type: A -annual, B -Biennial, P-Perenni I, WA -Winter Annual WestWater Engineering Page 8 of 18 4/9/2008 3.4 Recommended Treatment Strategies It is important to know whether the target is annual, biennial, or perennial to select strategies that effectively control and eliminate the target. Treatment strategies are different depending on plant type, which are summarized in Tables 3 and 4. In Section 3.5, the Life Cycle and Management Calendars section, (Figure 2) and Table 5, the best timing and strategies are illustrated for the noxious weeds found. Herbicides should not always be the first treatment of choice when other methods can be effectively employed. Table 3. Treatment Strategies for Annual and Biennial Noxious Weeds Target: Prevent Seed Production 1. Hand grub (pull), hoe, till, cultivate in rosette stage and before flowering or seed maturity. If seeds develop, cut and bag seed heads. 2. Chop roots with a spade below soil level. 3. Treat with herbicide in rosette or bolting stage, before flowering. 4. Mow biennials after bolting stage, before seed set. Mowing annuals will not prevent flowering but can reduce total seed production. irota Table 4. Treatment Strategies for Perennials Target: Deplete nutrient reserves in root system, prevent seed production 1. Allow plants to expend as much energy from root system as possible, do not treat when first emerging in spring, but allow growth to bud/bloom stage. If seeds develop, cut and bag if possible. 2. Herbicide treatment at bud to bloom stage or in the fall (recommended, after August 15 when natural precipitation is present). In the fall, plants draw nutrients into the roots for winter storage. Herbicides will be drawn down to the roots more efficiently at this time due to translocation of nutrients to roots rather than leaves. If the weed patch has been present for a long period of time, another season of seed production is not as important as getting the herbicide into the root system. Spraying in fall (after 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 plants 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'' h" - 1" 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. irota 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. 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.

It is also appropriate to control common mullein. One column that should be added is cutting of rosettes, which can be done any time during growing. Figure 2.

(Sirota 2004) WestWater Engineering Page 10 of 18 4/9/2008 3.6 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 tough noxious weeds. 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. 3.7 Best Management Practices — Noxious Weeds 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 re -seeded 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. WestWater Engineering Page 11 of 18 4/9/2008 In areas with slope greater than 3 percent, 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 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 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 translocation process. Most herbicide applications should use a surfactant if directed on the herbicide label or other adjuvants as called for on the herbicide label. Grazing: Grazing should be deferred, in reclaimed areas, until the desired grass species are established. Mechanical: Bull thistle was found in low density and is an example where control could be accomplished mechanically. Alternative Methods: An 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 percent 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 re- seeding 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. 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 WestWater Engineering Page 12 of 18 4/9/2008 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. Biological control in the project area using natural insect agents are either not available for the large infestations (such as redstem filaree or cheatgrass) or will be of little value for small infestations (such as plumeless thistle). 4.0 REVEGETATION - RECLAMATION 4.1 Pipeline ROW The pipeline traverses a variety of terrain including greasewood flats, sagebrush flats, small intermittent drainages, the riparian area of the Colorado River and drier ridge top areas and hillsides. The majority of the pipeline route follows an existing gas line that has previously been disturbed (Photo 4). The pipeline will disturb an area approximately 60 feet in width for a length of about 10.4 mile resulting in disturbance to previously reclaimed areas and native vegetation. The vegetation ranges from irrigated grass meadows and alfalfa fields to varying native vegetation depending on the site. Successful reclamation of the project area is dependent upon soil type and texture, aspect, slope, proper weed control and revegetation with suitable plant species. Photo 4. Existing gas line ROW north of Interstate 70 WestWater Engineering Page 13 of 18 4/9/2008 Weeds noted during the survey included common mullein, musk thistle, red -stemmed filaree, downy brome, bull thistle, plumeless thistle, houndstongue, halogeton, Russian olive and tamarisk. Other problematic weeds noted were Russian thistle and kochia. It is likely that additional weeds exist in this area because of the previous disturbance, making weed control in this location an important part of the reclamation. Construction of the new pipeline will create a new disturbance that could allow additional weeds to gain a foothold unless an effective monitoring and weed control program is implemented. Based on the soil types, terrain, and the presence of noxious weeds in the pipeline ROW, successful reclamation is most likely if a seed mix of grasses is used (Tables 6 and 7). This will allow control of noxious weeds while establishing vegetation in the disturbed areas. Two seed mixes are presented based on soil type and available moisture; one for the drier juniper/sagebrush sites and one for the meadow/riparian sites with more moisture. For best results and success, the recommended grass mixture reseeding should be done in late autumn. The reseeding rate should be doubled for broadcast application (CNHP 1998). 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. After desired grasses are established and control of target weed species is successful, then shrubs, forbs and trees can be planted without concern for herbicide damage. Few native forb seeds are available commercially as cultivars. Most are collected from natural populations. Native shrubs and forbs often do not establish well from seed, particularly when mixed with grasses. Past experience has shown that stabilizing the soil with grasses, accomplishing weed control, and then coming back to plant live, containerized woody species in copses has been the most cost effective method for establishing the woody species component of the plant community. For the pipeline ROW, grasses should be drilled after construction activities cease and the equipment removed from the site. After two years of controlling weeds (with herbicides) and allowing the grasses to become established, the forbs and woody species should be inter -seeded or hand -planted to increase the diversity and value of the reclamation plantings.

ETC Canyon Pipeline is seeking the special use permit to install a 24 -inch gas pipeline from Holmes Mesa to an existing interconnect approximately 2 miles north of Parachute, Colorado. The total length of the pipeline is 10.4 miles. The pipeline will be used to transport natural gas to an existing pipeline infrastructure owned by Enterprise Pipeline. The pipeline will be placed in an existing Right -of —Way (ROW) adjacent to pipelines owned by Williams Production RMT. Surface disturbance will occur in a 30 -foot permanent ROW and a 30 -foot temporary ROW, as well as three 2 -acre staging areas. The proposed pipeline is located on private lands that lie between the town of Parachute, Colorado, and Holms Mesa to the south of Rulison. The proposed pipeline begins at the gas plants approximately 2 miles north of Parachute, travels south for about 150 meters and then follows an existing pipeline ROW in an easterly path crossing County Road 215 ascending a steep hillside to the mesa immediately east of the county road. The pipeline then proceeds southeast where it parallels Interstate 70 eastward toward Rulison, Colorado. The pipeline alignment turns southeast, crossing I-70, to the frontage road south of I-70, the railroad and a small power line before crossing the Colorado River. From the Colorado River, the pipeline heads south along the edge of an irrigated alfalfa field, crosses County Road 309, and then continues south to its terminus on Holms Mesa. The topography along the pipeline route varies from flat irrigated meadows and hay fields to steep rocky sections with ph -ion -juniper and oakbrush. The pipeline crosses the Colorado River riparian habitat and a series of wetlands located in an overflow channel to the south of the river. Elevations along the pipeline route range from 5,146 feet near the Colorado River to 6,427 feet on Holms Mesa. Numerous natural gas well pads are adjacent to the pipeline alignment. Rural residences are widely spaced in the vicinity of the proposed pipeline alignment along County Road 309 and the Holmes Mesa area. The primary use of the surrounding area of the pipeline is agriculture/rangeland, wildlife habitat, and recent natural gas extraction/development. 1.2 General Survey Information In preparation for developing the following report, WWE biologists performed field surveys and assessments of wildlife, wildlife habitats, and habitats for sensitive plant species on the proposed pipeline alignment and surrounding area. WWE conducted the surveys on March 24 and 25, 2008. All areas of the survey were free of snow except for the steep north -facing slope below Holmes Mesa where patches of snow of 1- to 2 -foot depth existed. The purposes of the surveys were to determine the wildlife and sensitive plant species that occupy the project area at varying periods during the year and that would potentially be impacted as a result of the pipeline construction and operational activities. Factors considered include: I) soil type and texture; 2) existing land management; 3) absence or presence of wildlife and plant species; 4) habitat designations by Federal and State wildlife agencies; and 5) the present natural vegetation WestWater Engineering Page 1 of 23 pages April 2008 community. This report provides written documentation that describes survey findings as well as recommended mitigation measures to help offset potential impacts to wildlife and sensitive plants that occupy the project site and adjacent area. This assessment and mitigation plan meets the wildlife requirement of Garfield County Regulation 9.07.04 (10) (Board of County Commissioners 2006). 2.0 LANDSCAPE SETTING 2.1 Vegetation Vegetation communities along the pipeline route are categorized as pifion-juniper woodlands and mixed sagebrush and greasewood shrublands. Pifion-juniper woodlands are dominated by pinon pine (Pinus edulis) and Utah juniper (Juniperus utahensis) and can be mixed with an understory of mainly Wyoming sagebrush (Artemesia tridentata wyomingensis), forbs, and grasses (Photo 1). Numerous ephemeral washes bisect the alignment in the section that parallels Interstate 70, most often in a north to south flow pattern. Vegetation along the washes consists of greasewood (Sarcobatus vermiculatus), rabbitbrush (Chrysothamnus nauseosus), basin big sagebrush (Atermesia tridentata tridentata), and scattered four -winged saltbush (Atriplex canescens). The shrublands within the project area are composed primarily of Wyoming big sagebrush, greasewood, and rabbitbrush (Chrysothamnus viscidiflorus). Non-native downy brome (Bromus tectorum) dominates the understory for this shrubland community as well as the pinon juniper woodlands on and adjacent to Holmes Mesa. Photo 1. Pinon-juniper woodland with sagebrush WestWater Engineering Page 2 of 23 pages March 2008 Agricultural lands within the pipeline corridor include pasture land located southeast of the gas plants near County Road 215, pasture land located north of the Colorado River near Rulison, irrigated alfalfa south of the Colorado River near Rulison (Photo 2), and irrigated meadows on the alignment on Holmes Mesa. The pipeline also crosses through riparian and wetlands habitat found adjacent to the Colorado River. The vegetation in this area is composed primarily of Fremont cottonwoods (Populus fremontii), sumac (Rhus trilobata), Woods' rose (Rosa woodsii), and tamarisk (Tamarix ramosissima). Photo 2. Irrigated alfalfa field south of Colorado River 2.2 Soils The east terminus of the proposed pipeline sits atop Holms Mesa, primarily on Vale silt loam, 6 — 12% slopes. Native vegetation characteristic of Vale silt loam is Western wheatgrass (Pascopyrum smithii), prairie sandreed (Calamovilfa longifolia), needle and thread grass (Hesperostipa comata), rabbitbrush (Chrysothamnus nauseosus), and Utah serviceberry (Amelanchier utahensis). The pipeline will run north and descend very steep (up to 70%) slopes of Torriorthents and rock outcrop whose native characteristic vegetation is wheatgrass (Agropyron sp.), bluegrass (Poa sp.), Indian ricegrass (Oryzopsis hymenoides), sagebrush, (Artemesia sp.), pinon (Pinus edulis), and Utah juniper (Juniperus utahensis). As the pipeline continues north it descends the less steep flank of Holms Mesa consisting of Potts loam and Ildefonso stony loam, 12 — 45% slopes. Native vegetation characteristic of this soil complex is wheatgrass, needle and thread grass, Indian ricegrass, Utah serviceberry, pinon, and Utah juniper. WestWater Engineering Page 3 of 23 pages March 2008 Soils encountered as the pipeline crosses the Colorado River are Arvada loam, Torrifluvents, and Heldt clay loam. The soils in the riparian area are nearly level, have high water tables, and can be periodically flooded. Characteristic native vegetation of this soil complex is water tolerant grasses, sedges, rushes, greasewood, and cottonwood. The pipeline then runs westward, north of I-70, on primarily only one soil, Arvada loam, 1— 6% slopes. Characteristic native vegetation is western wheatgrass, alkali sacaton (Sporobolus airoides), inland saltgrass (Distichlis spicata), winterfat (Krascheninnikovia lanata), and greasewood. The pipeline route then ascends a hilly area generally consisting of Potts loam and Ildefonso stony loam, 3 — 12 % slopes. The descent into the Parachute Creek drainage crosses a short very steep area of badland, sparsely covered with Utah juniper and shrubs. The soils of the western terminus, near Parachute Creek, are primarly Heldt clay loam and Nihill channery loam on 1 - 6% slopes. The characteristic native vegetation of those soils are western wheatgrass, needle and thread grass, rabbitbrush, and basin big sagebrush (Artemesia tridentata tridentata). 3.0 WILDLIFE AND PLANT SURVEYS 3.1 Background Information Descriptions of critical habitats for federally -listed threatened, endangered and candidate fish and wildlife species were reviewed in the Federal Register, U. S. Department of the Interior, Fish and Wildlife Service (USFWS). Wildlife habitat (activities) maps, provided via the intemet web by the Colorado Division of Wildlife's (CDOW) "Natural Diversity Information Source" (NDIS), were reviewed and incorporated into this report in reference to state -listed threatened, endangered and species of "special concern"(CDOW 2008a). A list of Birds of Conservation Concern (BOCC) and their habitats for the Southern Rocky Mountain Region and the Colorado Plateau was reviewed. This list is published by the USFWS through a Memorandum of Understanding with the Bureau of Land Management (BLM) and the US Forest Service (USFS), which places high conservation priorities for BOCC species (USFWS 2002). Not all of these BOCC species occur regularly in Colorado, some are present only as seasonal migrants. Of those known to breed in Colorado, only a portion are known or suspected to breed within the vicinity of the proposed pipeline. Avian literature sources such as the "Birds of Westem Colorado Plateau and Mesa Country" (Righter et al. 2004) and the "Colorado Breeding Bird Atlas" (Kingery 1998) were reviewed to determine the likelihood for species occurrence within the project area. Bird identification and taxonomic nomenclature are in accordance with that applied by the Colorado Breeding Bird Atlas Project (Kingery 1998). Mapped soil types, as published by the Natural Resources Conservation Service (NRCS), U. S. Department of Agriculture, were reviewed to determine the soil types and vegetation characteristics of the project site and surrounding property (NRCS 2008). The determination of the presence/absence of suitable habitat for Threatened, Endangered and "Sensitive Species" plants (TESS) was based on previous WWE observations of typical habitat occupied by BLM or USFS sensitive plants, the Colorado Natural Heritage Program (CNHP) Rare Plant Field Guide (Spackman et al. 1997), and locations of species documented in the CNHP statewide database. WestWater Engineering Page 4 of 23 pages March 2008 3.2 Survey Methods A preliminary review of the project area using aerial photography maps was conducted to familiarize personnel with vegetation types and terrain and as an aid to help determine the likelihood of the presence of threatened, endangered or sensitive wildlife and plant species. Field data including general project location, boundaries and reported features were verified and/or recorded with the aid of a handheld global positioning system instrument (GPS) utilizing NAD83/WGS84 map datum, with all coordinate locations based on the Universal Transverse Mercator (UTM) coordinate system within Zones 12S and 13S. WWE biologists physically surveyed the area within 150 feet of both sides of the pipeline alignment to identify and locate wildlife species, wildlife sign (tracks, fecal droppings, vegetation disturbance, vegetation communities and wildlife habitats. Vegetation types were determined through field identification of plants, aerial photography, and on -the -ground assessments of plant abundance. Identification of plant species was aided by using pertinent published field guides (Whitson et al. 2004, CWMA 2007, Kershaw et al. 1998). Visual searches for raptor and other bird species nests were focused on rock cliffs, piton pine, Utah juniper, and Fremont cottonwood trees within a 0.25 mile distance from the pipeline's centerline. These searches included the rock outcrops east of Parachute Creek and north of Interstate 70. Nest searches and bird identification were aided with the use of binoculars and song recognition, where needed. Photographs were taken of the general project location, surrounding vegetation and terrain, and specific biological findings. 4.0 RESULTS OF SURVEY 4.1 TESS Plant Species Special status species of plants that may be present in the project area, and their habitats, are listed in Tables 1 and 2 in three categories: 1) Federally Listed Threatened or Endangered (1 species), 2) Federal Candidate Species (2 species), and 3) BLM Sensitive Species (5 species). Nomenclature and habitat descriptions are based on the CHNP literature (Spackman et al. 1997). Table 1.

Elevation: 5,800-9,000 ft Results: No TESS plants were observed during the biological survey. Potential habitat for Rocky Mountain thistle exists on the mesa east of Parachute creek, but no plants were observed. Appropriate elevations for Harrington beardtongue existed near Holms Mesa, but correct aspect and soils type were absent. The steep hillside to the east of County Road 215 has habitat suitable for Debeque milkvetch; however, none was observed during the survey. The closest known sites supporting the Debeque milkvetch are found in the northern portion of Sharrard Park and north of Webster Mesa. No known Debeque milkvetch populations will be affected by the proposed pipeline alignment. Suitable habitat for the other TESS plants listed in Tables 1 and 2 was not observed during this survey. 4.2 Federal Listed Threatened, Endangered, Candidate Wildlife Species No federal listed threatened, endangered or candidate wildlife species known to occupy the area of the proposed pipeline alignment and, thus, none of these species will be affected as a result of the proposed project. However, this section of the Colorado River where the pipeline crosses is designated critical habitat for the Federally endangered Colorado pikeminnow and razorback sucker. The Colorado pikeminnow and razorback sucker are discussed in more detail in Section 4.7.2, Fish. 4.3 State Listed Threatened, Endangered Special Concern Wildlife Species WWE biologists determined that four state listed threatened, endangered or special concern species may occur within the project area and are listed in Table 3 (CDOW 2008b).

Elevation: 3,000-11,000 ft * E= State Endangered, T= State Threatened, SC = Species of Concern During the surveys, no state listed threatened or endangered wildlife species were observed in the area of the proposed pipeline alignment. Bald Eagles are common winter residents on the Colorado River and utilize the cottonwood trees for night roosts, hunting perches and nesting. There are several nesting pairs of Bald Eagles on the Colorado River, with the closest nest site being west of Rifle, Colorado near Webster Hill. The Colorado River and adjacent mesas and drainages are utilized as hunting areas by the Bald Eagles. The eagles may also visit areas along Parachute Creek and adjacent mesas and slopes in search of winter forage in the form of fish and dead animal carcasses. Peregrine Falcons are summer residents in Colorado and the closest known nesting sites are found in the sheer cliffs of the Parachute and Clear Creek drainages. Habitats for bat species for roosting, breeding and hibernating, in the form of caves, mine shafts, walls and cliffs, could occur in the cliff areas to the north of the pipeline between Parachute and Rulison. Townsend's big -eared bat could occur in the area while foraging (CDOW 2008a). Potential habitat occurs along the Colorado River and Parachute Creek for northern leopard frog. Breeding habitat for northern leopard frog, in the form of shallow and quiet areas of water, occurs in the pipeline crossing at the Colorado River and wetlands complex on the south side of the river. 4.4 Birds of Conservation Concern (BOCC) Raptors: Several raptor (birds of prey) species nest, reside, forage or pass through the general area of the pipeline project. Raptor species that are common to the area include Golden Eagle, Red-tailed Hawk, American Kestrel, Cooper's Hawk, Peregrine Falcon and Great Horned Owl. The Bald Eagle, a common winter migrant, is discussed in Table 3 of this report. Numerous pifion pine, Utah juniper and cottonwood trees (Photo 3) encountered along and adjacent to the pipeline alignment are of sufficient height and density for tree nesting raptors. The rock outcrops WestWater Engineering Page 7 of 23 pages March 2008 east of Parachute Creek and southwest of the pipeline also contain suitable areas for nesting raptors. The cliffs north of the pipeline segment between Parachute and Rulison also contain a large number of rock outcrops suitable for use as nest sites by raptors. Photo 3. Raptor nest in Fremont cottonwood Raptor species that are listed as BOCC in the Southern Rockies and the Colorado Plateau, and which may occur in the project area, are listed in Table 4. In addition to the BOCC list, seven other species of raptors that could potentially be found nesting in the pipeline project area are also listed in Table 4. Table 4. Raptor species that may be present in the project area Common Name Scientific Name BOCC Habitat & Breeding Records Northern Harrier Circus cyaneus Y • Grassland, shrubland, agricultural areas, and marshes. Nests in areas with abundant cover(e.g.,tall reeds, cattails, grasses) in grasslands and marshes. Also known to nest in high -elevation sagebrush. Cooper's Hawk Accipiter cooperii N • Cottonwood riparian to spruce/fir forests, including pifion/juniper woodlands. Nests most frequently in pines and aspen. Sharp -shinned Hawk Accipiter striates N • High density young, or even -aged, stands of coniferous forest and deciduous forests of aspen or oak brush with small stands of conifers. Red-tailed Hawk ButeoN jamaicensis • Diverse habitats including grasslands, pifion-juniper woodlands and deciduous, coniferous and riparian forests. Nests in mature trees (especially cottonwood, aspen, and pines) and on cliffs and utility poles. WestWater Engineering Page 8 of 23 pages March 2008 Table 4. Raptor species that may be present in the project area Common Name Scientific Name BOCC Habitat & BreedingRecords Swainson's Hawk Buteo swainsoni Y • Typically, arid grassland, desert, agricultural areas, shrublands and riparian forests. Nests in trees in or near open areas. Golden Eagle Aquila drrysaetos Y • Grasslands, shrublands, agricultural areas, pifion-juniper woodlands, and ponderosa forests. Prefers nest sites on cliffs and sometimes in trees in rugged areas. American Kestrel Falco sparverius N • Coniferous and deciduous forests and open terrain with suitable perches. Nests in cavities in trees, cliffs and buildings. Peregrine Falcon Falco peregrines Y • Ph -ion -juniper woodlands and coniferous and riparian forest near cliffs. Nests on ledges of high cliffs away from human disturbance. Prairie Falcon Falco nexicanus y • Grasslands, shrublands, and alpine tundra. Nests on cliffs or bluffs in open areas. Great Horned Owl Bubo virginianus N • Occupies diverse habitats including riparian, deciduous and coniferous forests with adjacent open terrain for hunting. Northern Saw- whet Owl Aegolius acadicus N • Mountain and foothills forest and canyon country. Significant use of pinon-juniper woodland and Douglas - fir. Long-eared Owl Asia otus N • Occupies mixed shrublands. Nests and roost in sites in dense cottonwoods, willows, scrub oak, junipers and dense forest of mixed conifers and aspens. Previous surveys had noted an American Kestrel nest in the cottonwood trees of Parachute Creek immediately west of the pipeline. However, the tree containing the nest site had blown down and no kestrel activity was observed in the area during this survey. Three raptor nests identified in previous surveys were observed in the rock outcrops east of Parachute Creek (Figure 1). One nest (RTHA-4) appeared to be used by ravens, while no activity at the other two nest sites was observed. One Red-tailed Hawk was seen soaring in the vicinity of RTHA- 3, but no nest maintenance activity was observed. Use of these nest sites by Red-tailed Hawks is still possible as it is early in the nesting season and nest initiation is just beginning for red -tails. Red-tailed Hawk nesting activity was observed at a cliff nest (RTHA-1) previously identified in the rock outcrop north of the Parachute to Rulison pipeline segment (Figure 1, Photo 4). Birds were observed carrying stick materials to the nest, an indication of nesting activity. No other nesting activity was observed at the other nest sites found during this survey. While no nesting activity was noted, it is still early for most species except owls and eagles. In this portion of Colorado, the raptor nesting season is generally considered to occur between mid-February and mid-August. Typically, owls and eagles are the first raptors to begin the annual nesting cycle followed by members of the Genus Accipiter, Buteo, Circus and Falco. Usually, by mid-August all young birds have fledged and left the nest. WestWater Engineering Page 9 of 23 pages March 2008 Photo 4. Active Red-tailed Hawk in rock outcrop WWE biologists assigned nest sites to specific raptor species based on knowledge of raptor occurrence in this area, as well as design, location, materials, and configuration of nesting structures. A complete list of raptor nests observed during this survey is found in Table 5 and Figure 1. Table 5.

BOCC habitat and nesting records, as described in the Colorado Breeding Bird Atlas (Kingery 1998), Colorado Birds (Andrews and Righter 1992) and Birds of Western Colorado Plateau and Mesa Country (Righter et al. 2004) in the vicinity of the pipeline are summarized in Table 6. WestWater Engineering Page 11 of 23 pages April 2008 Table 6. BLM sensitive & migratory bird species that may be present in the project area Common Name Scientific Name Habitat & Breeding Records Pinion Jay Gymnorhinus cyanocephalus • Pifion-juniper woodlands; nests in pinons or junipers. • Confirmed breeder in Garfield County in the vicinity of the pipeline. Black -throated Gray Warbler Dendroica nigrescens • Mature pifion-juniper woodlands; nests on horizontal branches in Piiion or juniper. • Confirmed breeder in Garfield County in the vicinity of the pipeline. Lewis' Woodpecker Melanerpes lewis • Open stands of cottonwood and ponderosa pine; nests in cottonwood in riparian settings, ponderosa pine and aspen. • Possible breeder in Garfield County. Virginia's Warbler Vermivora virginiae • Dense shrublands and scrub forests of Gambel oak, pifion-juniper, mountain mahogany or ponderosa pine. Nests on the ground among dead leaves or on rock or log overhangs. • Nesting has been confirmed in Garfield Counties, including the Roan Plateau. Unlikely nester in the project area. Brewer's Sparrow Spizella breweri • Sagebrush, greasewood and rabbitbrush in desert valleys; nests in sagebrush. • Confirmed breeder in Garfield County in the vicinity of the pipeline. The species most likely to nest in this project area include the Pinyon Jay and Black -throated Gray Warblers, which prefer mature pifion-juniper woodlands for nesting. The primary suitable habitat for nesting would be in the pinon juniper woodlands in the segments of the pipeline near Parachute and on Holms Mesa. There are suitable patches of sagebrush available for Brewer's sparrow to nest in within the project area. The cottonwood riparian vegetation along the Colorado River appears to be suitable nesting habitat for Lewis' Woodpecker. Virginia's Warbler is an unlikely nester in the project area. No BOCC species were observed during the surveys since the surveys were not conducted during the breeding or nesting periods. 4.6 Terrestrial Species 4.6.1 American Elk and Mule Deer CDOW places the proposed pipeline within Game Management Units (GMU) 32 and 42. In GMU 32 and 42, the pipeline is situated within mule deer and American elk overall range and winter range. The west end of the pipeline northeast of Parachute passes through a portion of elk severe winter range and an elk winter range concentration area (Figure 2). The east end of the pipeline on Holms Mesa is also classified as elk severe winter range. Mule deer severe winter range is found on the north side of Interstate 70 on the pipeline segment between Parachute and Rulison, while the area south of the Interstate is classified as mule deer severe winter range and as a winter concentration area. The area on Holmes Mesa is classified as a mule deer winter concentration area (Figure 3). CDOW defines "winter range" as "that part of the overall range where 90 percent of the individuals are located during the average five winters out of ten from the first heavy snowfall to spring green -up". CDOW defines a "winter concentration area" as "that part of the winter range where densities are at least 200 percent greater than the surrounding winter range density during WestWater Engineering Page 12 of 23 pages March 2008 the same period used to define winter range in the average five winters out of ten". "Severe winter range" is defined as "that part of the range of a species where 90 percent of the individuals are located when the annual snowpack is at its maximum and/or temperatures are at a minimum in the two worst winters out of ten." During the surveys, numerous deer, fresh tracks, beds, antler rubs and fecal pellets were observed in areas where sagebrush and/or pinon pine and juniper trees were present (Photo 5). Significant browsing by deer on available sagebrush and rabbitbrush was observed where these plant species occurred, especially in the openings in the pinon juniper and meadow edges. Evidence of deer and elk use in the meadows east of Parachute Creek, in the riparian corridor of the Colorado River and on Holms Mesa was observed. Mule deer rely on the existing sagebrush and shrubs above the snow for their primary food source, while elk rely primarily on available grasses for food. Adjacent areas of pinon pine and juniper trees provide necessary escape, thermal and loafing cover for deer and elk (Photo 6). Deer and elk were observed in areas adjacent to the pipeline throughout the survey. Photo 5. Deer pellets in sagebrush opening Photo 6. mule deer in pinon-juniper cover 4.6.2 Black Bear and Mountain Lion CDOW "NDIS" mapping shows the proposed pipeline to be within overall range for black bear and mountain lion. The vegetation of the proposed project site does not provide adequate food sources for black bear to be routinely attracted to the area. However, it is not uncommon for black bear to travel through the surrounding area during periods of short natural food supplies as bears search for food. During these periods black bears may be attracted to human -related food sources such as garbage and cooking areas. Mountain lion typically follow migrating deer herds in search of deer as the primary food source. Mountain lion have large territories and are highly mobile as they search for food or new territories. Mountain lion prefer to hunt in rocky terrain with trees or shrubs. This habitat condition occurs within the cliff areas north of the pipeline between Parachute and Rulison as well as the steep slopes at the south edge of Holms Mesa. Mountain lion could travel through and hunt in these areas, especially when deer are present during the winter period. WestWater Engineering Page 15 of 23 pages January 2008 4.6.3 Small Mammals Common small mammal species (small game, furbearers, non -game) include mountain cottontail, coyote, bobcat, striped skunk, porcupine, deer mouse and least chipmunk. Several cottontails and chipmunks were observed along the pipeline ROW during the survey. Fringed myotis and spotted bat are two bat species of the area that are considered "sensitive" by the BLM and could possibly forage for airborne insects through the area of the project (Reid 2006). Townsend's big -eared bat is previously discussed in the section on "State Listed Threatened, Endangered Special Concern Wildlife Species". Roosting, breeding and hibernating habitats for bats in the form of caves, mine shafts, walls and cliffs occur near the pipeline alignment, especially in the cliff areas to the north of the pipeline segment between Parachute and Rulison. 4.6.4 Other Bird Species The project areas' sagebrush, pinon pine, Utah juniper, cottonwood riparian, wetlands and grass under -stories provide nesting and foraging habitats for various other migratory and non - migratory bird species, depending on the season of the year (Photo 7). Bird species observed during the survey included House Finch, Black -billed Magpie, American Crow, Common Raven, Dark -eyed Junco, Mountain Bluebird, Black -capped Chickadee, Plain Titmouse, White -breasted Nuthatch, Red -winged Blackbird, Canada geese and numerous species of ducks. The Mourning Dove is the most common game bird in the area (Righter et al. 2004) and likely nests in trees and ground settings throughout this area. Habitat for Wild Turkey occurs in the area of the proposed pipeline (CDOW 2008a) and two birds were observed on the bench above County Road 309 during this survey. Photo 7. Riparian Vegetation and Wetlands South of Colorado River WestWater Engineering Page 16 of 23 pages March 2008 4.6.5 Reptiles Plateau striped whiptail, sagebrush lizard, side -blotched lizard, plateau lizard, bullsnake, and western rattlesnake are reptiles common to this region and could occur in the vegetation and terrain of the project property (Hammerson 1999). 4.7 Aquatic Species 4.7.1 Amphibians Great Basin spadefoot is an amphibian species that could occur on the property since it is common to the pit -ion -juniper woodland and sagebrush shrublands of the area (Hammerson 1999). This species breeds during summer periods in temporary pools in ravines and drainages that experience water flow after heavy rain events. Potential habitat for northern leopard frog occurs along the Colorado River and associated overflow channels and wetlands. 4.7.2 Fish No fish inventories were conducted as part of this survey. However, the location where the pipeline crosses is considered part of designated critical habitat for the Federal endangered Colorado pikeminnow and razorback sucker. Federally listed, Colorado critical habitat for Colorado pikeminnow occurs in the upper Colorado River in Mesa and Garfield Counties. It extends in its 100 -year floodplain from the Colorado River Bridge at exit 90 (Rifle town exit) north off Interstate 70 (T6S, R93W, section 16 (6th Principal Meridian) to the Colorado -Utah state line. Additional critical habitat occurs in Utah. The razorback sucker's designated critical habitat in Colorado includes Mesa and Garfield Counties. The habitat includes the Colorado River and its 100 -year floodplain from Colorado River Bridge at exit 90 (Rifle town exit) north off Interstate 70 (T6 S, R93 W, Section 16 (6th Principal Meridian) to WestWater Canyon in T20S, R25E, Section 12 (Salt Lake Meridian). Other designated habitat includes the Gunnison River and its 100 -year floodplain from the Redlands Diversion Dam in T1 S, R1 W, Section 27 (Ute Meridian) to the confluence with the Colorado River in T1 S, R1 W, Section 22 (Ute Meridian). The present distribution of the Colorado pikeminnow includes the Green River below the confluence with the Yampa River; the lower Duchesne River in Utah; the Yampa River below Craig, Colorado; the White River from Taylor Draw Dam near Rangely, Colorado, downstream to the confluence with the Green River; the Gunnison River in Colorado; and the Colorado River from Palisade, Colorado, downstream to Lake Powell. The closest known currently occupied area is located in the Colorado River approximately 30 miles downstream of the proposed pipeline crossing. Habitat requirements of this species depend on the life stage and time of year. Young -of -the year and juveniles prefer shallow backwaters, while adults prefer pools, eddies, and deep runs (Miller et al. 1982). Throughout most of the year, juvenile, subadult, and adult Colorado pikemirmow utilize relatively deep, low-velocity habitats that occur in nearshore areas of main river channels. However, in spring when discharge is high due to snow -melt runoff, Colorado pikeminnow adults utilize flood plain wetlands, flooded tributary mouths, flooded side canyons, and eddy habitats that are accessible only during high flows. WestWater Engineering Page 17 of 23 pages March 2008 The FWS has conducted electro -shocking surveys in the Colorado River from Beaver Tail Mountain (in Debeque Canyon) to Silt annually since 2004 in an effort to detect the presence of endangered fish species. According to the FWS in Grand Junction (Burdick pers. comm. 2008), these surveys have not documented the presence Colorado pikeminnow. The present distribution of the razorback sucker is limited to the upper Green River in Utah, lower Yampa River in Colorado, and occasionally the Colorado River near Grand Junction, Colorado. Habitat requirements for razorback sucker can be met in both riverine and reservoir environments. General habitat used by adults consist of eddies, pools, and backwaters during the non -breeding period (July through March) (Maddux et al. 1993). Runs, backwaters, and flooded off -channel impoundments are used during breeding. Juveniles seem to prefer shallow water in backwaters, tributary mouths, and off -channel impoundments. Habitats used by adult razorback suckers in rivers of the Upper Colorado River Basin include deeper runs, eddies, backwaters, and, at higher discharges, flooded off -channel environments in spring (the latter apparently including movements from the colder main channel into warmer habitats, a behavior called "staging," before spawning); runs and pools often in shallow water associated with submerged sandbars in summer; and low-velocity runs, pools, and eddies in winter. Young razorback suckers require nursery environments with quiet, warm, shallow water such as tributary mouths, backwaters, or inundated flood plain habitats in rivers and coves or shorelines in reservoirs. The FWS has conducted electro -shocking surveys in the Colorado River from Beaver Tail Mountain (in Debeque Canyon) to Silt annually since 2004 in an effort to detect the presence of endangered fish species. According to the FWS in Grand Junction (Burdick pers. comm. 2008), these surveys have not documented the presence any razorback sucker during this survey period. Care should be taken during construction to contain any sediment that could enter the river and affect water quality for fish and other aquatic organisms. 5.0 IMPACTS TO WILDLIFE 5.1 Wildlife Impact Assessment Construction of the pipeline will cause disturbance within the ROW to native vegetation and wildlife habitat. Foreseen impacts would be (1) the loss of winter range to a small number of mule deer and elk that utilize this site, (2) the loss of foraging and nesting vegetation/habitat to a small number of bird species, and (3) the possible disturbance to raptor nests adjacent to and within the pipeline corridor. The casual human disturbance that will be associated with the pipeline construction activities will indirectly cause some wildlife species to avoid the area, at least during the periods of human activity. Some species will become accustomed to the human activity while maintaining a distance that is tolerable. The impact to wildlife as a result of the pipeline installation and operation is relatively minimal and would not affect the overall status of wildlife populations of the area. The project and its ongoing activities will contribute; however, to the overall cumulative impacts to the wildlife populations of the area that are experiencing gradual habitat loss, fragmentation, alteration and displacement through increased development. WestWater Engineering Page 18 of 23 pages March 2008 6.0 MITIGATION RECOMMENDATIONS The following suggestions for mitigation are presented for maintenance and improvement of wildlife habitat quality as well as for the prevention of human -caused wildlife losses and/or conflicts. 6.1 Maintenance and Restoration of Habitat In the Rocky Mountain Region sagebrush communities have declined over the years and continue to do so as a result of development and habitat conversion. Sagebrush is a key food source for wintering mule deer on this project site and provides nesting and foraging habitat for a variety of migratory birds and small mammals. The grass understory of the current sagebrush, piflon-juniper vegetation and adjacent meadows provides valuable forage for wintering elk. After disturbance and removal, it generally takes decades to return sagebrush to its current condition through natural vegetative succession. Deliberate planting of sagebrush is possible, yet costly. Native Wyoming and basin big sagebrush should be considered and added to the re - vegetation plan of disturbed soils once grass/forb plantings have established themselves. Seed from the existing sagebrush vegetation should be used to create wildlife forage that has a mix of grasses, forbs and sagebrush. Any further energy exploration and/or development in this area, such as future pipeline installations, should include efforts to maintain and/or restore the sagebrush community. Ongoing control of noxious and invasive weeds is recommended as an additional method to maintain native vegetation communities and favorable wildlife habitats. An "Integrated Vegetation and Weed Management Plan" is provided for this project in a separate report. 6.2 Off-site Mitigation A temporary loss of wildlife habitat will occur as result of habitat alteration for the pipeline installation. Habitat loss will be permanent in areas where vegetation reclamation is unsuccessful. Some species of wildlife will benefit when the disturbed vegetation of the pipeline corridor is reclaimed with introduced plant species; yet other species will not benefit as a result of a change in the native vegetation complex. For example, disturbance and removal of sagebrush will cause long term winter habitat loss to mule deer until native sagebrush becomes re-established. This habitat loss contributes to the overall cumulative impacts to wildlife as a result of increased development in this region. Efforts to conduct or contribute to off-site habitat mitigation in the local area, especially for deer and elk winter range, would help offset net habitat losses to these species. Off-site mitigation could be in the form of habitat improvement or habitat acquisition that protects key habitats in perpetuity. CDOW is a key agency to contact for suggestions and recommendations toward off-site wildlife habitat mitigation. 6.3 Planning for Sensitive Time Periods 6.3.1 Mule Deer and Elk Wintering mule deer and elk would benefit if construction and/or energy exploration/ development activities avoided the critical time for these species from December 1 to April 30. Energy industry activities are commonly limited during this time period on federal lands of the WestWater Engineering Page 19 of 23 pages March 2008 area in order to accommodate wintering mule deer and elk. Table 7 displays the most critical periods for deer and elk in the area of the pipeline project. Table 7. Seasonal critical periods for Rulison Enterprise Pipeline Concern Period Deer and Elk severe (critical) winter range December 1 — April 30 Migratory Birds primary nesting season May 15 — August 1 Raptor nesting season February 1 — August 15 6.3.2 Migratory Birds Vegetation clearing activities, in relation to construction and development projects, would have less impact to migratory birds if conducted outside the primary nesting season of May 15 to August 1 (Table 7). 6.3.3 Raptors Activities associated with the proposed project have the potential to impact raptor populations. In order to reduce the potential for impacts to nesting raptors, it will be important that the project proponent schedule construction activities such that they do not interfere with breeding, nesting and brood rearing activities (Table 7). CDOW's (Craig 2002) recommended raptor nest site avoidance standards for the species observed in this survey are summarized below (Table 8). If the project cannot be completed prior to, or after, the next nesting season, the known nest should be re -inventoried by qualified biologists. If any birds are found behaving in a manner consistent with nesting, every effort should be made to apply the timing limitation and buffer distance stipulations. Table 8.

Keep activity to a minimum during breeding season. WestWater Engineering Page 20 of 23 pages March 2008 6.4 Other Mitigation Practices 6.4.1 Erosion Control and Soil Stability Efforts to control soil erosion within the project area should be implemented. Disturbed soils within the pipeline corridor will be highly susceptible to erosion and downstream water quality could be negatively affected by increased soil erosion. Boring beneath the Colorado River and associated wetlands for the pipeline stream crossing would minimize disturbance to the soils and vegetation of the stream bed and banks, thus, reducing downstream silt and sediment loads that can affect water quality for endangered fish critical habitat areas and other aquatic life. 6.4.2 Fences Several livestock fences will be dismantled and re -built as part of the pipeline construction project. Re -built fences that are designed for easy passage of deer and elk can allow these animals to utilize the native and planted vegetation for forage and move about the adjacent areas freely as they search for food and cover. In addition, properly designed fences will prevent deer and elk from being injured or suffering death as a result of becoming entangled as they attempt to jump over or pass through a fence. Generally, wire fences that do not exceed 42 inches in height and have 12 -inch spacing between the top two wires will allow deer and elk to pass over a fence without conflict. The BLM utilizes these fence specifications for livestock fencing on federal lands (BLM 1989). The publication presented by CDOW, "Fencing with Wildlife in Mind" provides fence designs that are friendly to wildlife and is available at the CDOW web site at http://wildlife.state.co.us/NR/rdonlyres/B0D65D61-6CB0-4746-94F1- 6EE 194E1 C230/0/fencing.pdf. 6.4.3 Traffic Construction and service vehicle drivers should be encouraged to maintain modest speeds to reduce the chances of striking wildlife on public and private roads. Advisory signs with this cautionary message could be placed on roadways of the area. Posting speed limit signs where collisions with wildlife appear most likely, on County Roads and energy -industry roads, will help reduce losses to wildlife as a result of vehicle encounters. 6.5 Mitigation Summary Table 9 briefly summarizes the mitigation measures mentioned in this report, which can help to reduce impacts to wildlife as a result of the Rulison Enterprise Pipeline project.
