Production equipment separates the fluids and the fluids are stored in tank(s) until removal for sale or disposal. Oil and water are removed by truck load -out or by pipeline. Fluids are moved within the facility by pipeline. SPCC Plan Page 4 This production facility(ies) receives, processes, and stores production 24 hours a day, 365.25 days a year. The facility is not manned but an operator inspects the facility daily to weekly. The area surrounding the field is grass and rangeland. There are residences in the field. Individual tanks and production equipment at the facility are described in Appendix A. Drainage pathways and distances to navigable waters are also described in Appendix A. The following information, as appropriate, is included in the site diagrams and descriptions in Appendix A: 1. Containers (including aboveground storage tanks [ASTs], drums, separation and other equipment) and their contents 2. Tanker truck loading and unloading areas 3. Buried or bunkered tanks 4. Drum and portable container storage areas 5. Piping 2.5 Plan Implementation (112.7) Any additional facilities, procedures, methods, or equipment not yet fully operational shall be discussed with the details of installation and start-up (40 CFR 112.7). The sites are discussed individually in Appendix A. Any items not yet fully operational will be completed as soon as practical, but no later than six months following the date of this plan. New individual sites shall have spill prevention and control measures in place at the time production for the site begins. 2.6 Facility Conformance The subject facilities are in conformance with 40 CFR 112 as amended on July 17, 2002, with the following exceptions noted below. The reason for any nonconformance, including impracticable containment or diversion measures, and the provided equivalent environmental protection measures are also noted.

Expected maximum flow rates, flow directions, and maximum quantities for individual sites are listed in Appendix A. Bulk Storage Tank Leak or Failure Failure Modes: Corrosion, vandalism, lightning strikes, valve or piping failure, overfilling. II. Rate of Flow: Variable, depending upon the type, size and location of the tank failure. The ambient temperature at the time of the release may affect the viscosity of the oil and thereby impact the rate of flow. Flow rates for corrosion failure are typically low, ranging from less than a gallon per day to a gallon per hour. Flows resulting from valve and piping failures or vandalism typically range from a gallon per hour up to the tank contents per hour. Lightning strikes may result in a release that is essentially instantaneous. III. Discharge Quantity: Variable depending upon the type and location of the failure. The total quantity discharged would not exceed the working capacity of the largest tank. IV. Preventative Measures: Storage tanks are constructed in accordance with API industry standards. Materials used in constructing the tanks are compatible with the substances stored. Where practicable, earthen berms or other diversionary structures are utilized to control any released fluids. Compacted natural clay/loam bases and berms with gravel armor or concrete are utilized for containment in the event of a release from and of this type equipment. The containment areas are constructed to contain a minimum of 100% of the single largest container within the containment structure plus freeboard for precipitation. Tanks are appropriately sized to minimize the risk of overfilling. Tanker Truck Loading and Unloading Operations SPCC Plan Page 6 Failure Modes: Piping or valve failure, tank failure, overflow, and human error. II. Rate of Flow: Variable depending upon the type, size and exact location of the failure, and the amount of oil in the tanker truck and storage tank. The ambient temperature at the time of the release may affect the viscosity of the oil and thereby impact the rate of flow. Flow rates resulting from piping and valve failures can range from 1 gallon per hour up to the tank contents in less than one hour. The flow rate for tank truck overflows typically will not exceed 5 to 10 bbls per minute. Tank failures may result in releases that are essentially instantaneous. IH. Discharge Quantity: Variable depending upon the type and location of the failure. The total quantity discharged would not exceed the working capacity of the largest tank. IV. Preventative Measures: Oil production is removed from the facility by truck. Tanker truck loading and unloading operations are conducted in accordance with United States Department of Transportation regulations (49 CFR 177). All loading operations are attended by the truck driver. No smoking or open flames are allowed in the vicinity of the storage tanks and loading area. Following the completion of loading operations, the transfer line is disconnected and all valves and outlets on the tanker truck and the storage tank are visually inspected for leakage prior to vehicle departure. Process Unit Failure (Separator/Heater Treater/Gun Barrel) Failure Modes: Process vessels may rupture or associated lines, valves and gauges may fail or leak. Leaks from corrosion or at valves and connections. If pressure relief valves dump to a flare or vent, this may result in a release. II. Rate of Flow: Variable, depending upon the mode and extent of the failure. The maximum expected rate of flow from a process unit failure is the oil production rate of the well plus any additional fluid volume contained in the vessel above the elevation of the rupture. III. Discharge Quantity: Variable, depending on the type of failure and the length of time that the failure went undetected. VI. Preventative Measures: Process units are constructed in accordance with API and ASME industry standards. Where practicable, earthen berms or other diversionary structures are utilized to control any released fluids. Piping Failure Failure Modes: Both aboveground and buried pipelines may rupture or corrode and leak. Associated flanges, screwed connections, valves and gauges are also subject to corrosion and may fail or leak. Piping may be damaged from construction activities. At the wellhead, there may be leaks at the stuffing box, valves, and connections. II. Rate of Flow: Variable, depending on the size and location of the piping -related failure. The maximum potential rate of flow is not expected to exceed the oil production rate. III. Discharge Quantity: Variable depending upon the type and extent of the failure and the length of time that the failure went undetected. IV. Prevention Measures: Flowlines to the tank battery are steel and/or poly pipe. Flowlines are typically buried and secondary containment is not practicable. Corrosion inhibitor is utilized to prevent SPCC Plan Page 7 corrosion. During pipeline excavation projects pipelines are inspected for signs of excessive corrosion or stress. Personnel routinely perform visual inspections of aboveground piping and buried flowline right-of- ways to detect leaks and/or failures. Lines are repaired or replaced as appropriate if leaks, failures, excessive corrosion or stress are indicated. 2.8 Containment and/or Diversionary Structures [112.7(c)] The aboveground storage tanks have berms for secondary containment. Secondary containment for truck loading/unloading area, separation equipment, and piping is not practicable in many instances. See Appendix A for site-specific information. See Appendix B for the oil spill contingency plan. Contact information for company personnel, cleanup and other contractors, and government regulatory agencies is included in Appendix C. The central depot for spill response equipment is the Field Office. Granular absorbent material, pads, booms, shovels, brooms, earthmoving equipment for spill containment, and empty drums are available for dispatch from this site. Oil transport trucks, including contract oil haulers, carry spill control kits. 3.0 INSPECTIONS PROCEDURES (112.7 e) The pumper will informally inspect the production equipment in his area on each visit (daily to weekly). A formal inspection of the production equipment will be conducted, documented, and signed by the operator at least annually. The following will be used as a guide for the informal and formal inspections. Note condition of any piece of equipment, storage tank or drum, and other items that could lead to a spill or adversely effect the operations or safety of the facility. An example site inspection checklist is included in Appendix D. Annual facility inspection records are kept on file for a minimum of three years. A record of inspections and drainage events will be recorded in the remarks section of the Lease Inspection Forms. 4.0 DISCHARGE PREVENTION AND RESPONSE TRAINING PROGRAM At a minimum train your oil handling personnel in the operation and maintenance of equipment to prevent discharges; discharge procedures protocols; applicable pollution control laws, rules, and regulations; general facility operations; and the contents of the SPCC Plan. 112.7(1) (1) Schedule and conduct discharge prevention briefing for your oil handling personnel at least once a year to assure adequate understanding of the SPCC Plan for the facility. 112.7(/) (3) 4.1 Training Requirements Personnel will be instructed in the operation and maintenance of equipment used at this facility to prevent discharges of oil and in applicable pollution control laws, rules, and regulations.

You shall instruct your personnel to be alert at all times to prevent damage to equipment in your work area. If at any time that your personnel determine that a spill may occur or has occurred, you are instructed to notify a company representative so that he can be present for instructions and assistance. On completion of your operation, you shall return the area to its original condition. 6.0 OIL PRODUCTION FACILITY DRAINAGE [112.9(b)]: 6.1 Drainage of Rainwater from Facility 112.9(b)(1) At tank batteries and separation and treating areas where there is a reasonable possibility of a discharge as described in § 112.1(b), close and seal at all times drains of dikes or drains of equivalent measures required under § 112.7(c)(1), except when draining uncontaminated rainwater. Prior to drainage, you must inspect the diked area and take action as provided in § 112.8(c)(3)(ii), (iii), and (iv). You must remove accumulated oil on the rainwater and return it to storage or dispose of it in accordance with legally approved methods. (2) Inspect at regularly scheduled intervals field drainage systems (such as drainage ditches or road ditches), and oil traps, sumps, or skimmers, for an accumulation of oil that may have resulted from any small discharge. You must promptly remove any accumulations of oil. SPCC Plan Page 10 a. Drainage from diked storage areas is controlled as follows: 112.9(b)(1) The containment areas are inspected several times per week when operating personnel visit the site. Any accumulation of oil resulting from a discharge is promptly removed. No drainage from containment areas should be required. Water accumulated in the bermed areas will be inspected to insure compliance with applicable water quality standards and will not create a harmful discharge as defined in 40 CFR part 110.3 which includes oil that causes a film or sheen upon or discoloration of the surface of the water. If necessary, fluids within the containment area will be recovered and placed back into the production system or taken to an approved disposal site. Personnel must record any drainage events, including date, hydrocarbons present, and volume drained. A Stormwater Inspection Procedure and Drainage Record Form is presented in Appendix F. b. Drainage from undiked areas is controlled as follows: 112.9(b) (2) Hydrocarbon storage vessels are located within bermed areas to prevent spills into undiked areas. Field drainage dikes and road ditches will be inspected for accumulation of oil or oil contaminated soil. 7M BULK STORAGE CONTAINERS/SECONDARY CONTAINMENT [112.9(c)] 7.1 Tank compatibility with its contents: 112.9(c)(1) Not use a container for the storage of oil unless its material and construction are compatible with the material stored and the conditions of storage. The ASTs onsite are constructed of welded steel in accordance with API standards. The tanks are specifically designed to hold oil and/or water and the materials of construction are compatible with the contents. 7.2 Secondary containment: 112.9(c)(2) Provide all tank battery, separation, and treating facility installations with a secondary means of containment for the entire capacity of the largest single container and sufficient freeboard to contain precipitation. You must safely confine drainage from undiked areas in a catchment basin or holding pond. The permanent secondary containment has been designed to hold the entire contents of the largest tank with sufficient freeboard to allow for precipitation. The gas/liquid separator and associated piping do not have secondary containment, but the facility is covered by an oil spill contingency plan and a commitment of manpower, equipment, and materials. SPCC Plan Page 11 7.3 Container Inspection 112.9(c)(3) Periodically and upon a regular schedule visually inspect each container of oil for deterioration and maintenance needs, including the foundation and support of each container that is on or above the surface of the ground. Personnel view and informally inspect aboveground storage tanks several times per week as part of their routine maintenance schedule. Aboveground storage tanks, secondary containment and associated equipment are formally inspected on an annual basis. During these inspections, the outside of each tank is observed for evidence of deterioration, leaks which might cause a spill, or accumulation of oil inside diked areas. These annual facility inspections are documented. A sample facility inspection form is presented in Appendix D. 7.4 Tank Battery Engineering 112.9(c) (4) Engineer or update new and old tank battery installations in accordance with good engineering practice to prevent discharges. You must provide at least one of the following: (i) Container capacity adequate to assure that a container will not overfill if a pumper/gauger is delayed in making regularly scheduled rounds. (ii) Overflow equalizing lines between containers so that a full container can overflow to an adjacent container. (iii) Vacuum protection adequate to prevent container collapse during a pipeline run or other transfer of oil from the container. (iv) High level sensors to generate and transmit an alarm signal to the computer where the facility is subject to a computer production control system. Tank capacities are such that greater than 30 days is required for the tank capacities to be reached. Tank capacity is monitored at least once per week, weather and road conditions permitting, as part of the facility operating report. 8.0 TRUCK LOADING/UNLOADING [112.7(a)(3)(ii)] AND FACILITY TRANSFER OPERATIONS, OIL PRODUCTION FACILITY [112.9(d)] 8.1 Truck Loading/Unloading 112.7(a)(3) Describe in your Plan ... (ii)Discharge prevention measures including procedures for routine handling of products (loading, unloading, and facility transfers, etc.); 112.7(h) applies only to tank car and tank truck loading/unloading racks. Because the facility does not have a loading/unloading rack, section 112.7(h) is not applicable. The following measures will be implemented: SPCC Plan Page 12 Oil production is removed from the facility by truck. Tanker truck loading and unloading operations are conducted in accordance with United States Department of Transportation regulations (49 CFR 177). All loading operations are attended by the truck driver. No smoking or open flames are allowed in the vicinity of the storage tanks and loading area. Following the completion of loading operations, the transfer line is disconnected and all valves and outlets on the tanker truck and the storage tank are visually inspected for leakage prior to vehicle departure. 8.2 Inspection 112.9(d) (1) Periodically and upon a regular schedule inspect all aboveground valves and piping associated with transfer operations for the general condition of flange joints, valve glands and bodies, drip pans, pipe supports, pumping well polish rod stuffing boxes, bleeder and gauge valves, and other such items. Pipelines are 2 -inch diameter lines or less with a maximum length of a few hundred feet. All piping associated with transfer operations is coated to prevent corrosion. Personnel view and informally inspect aboveground valves and piping several times per week as part of their routine maintenance schedule. Any deficiencies or equipment failures are reported to the field supervisor and corrected promptly. Aboveground valves and piping are formally inspected on an annual basis. These annual facility inspections are documented on the facility inspection form shown in Appendix D. Buried piping is not uncovered for inspections, but if uncovered for any reason, the piping and associated equipment is examined for evidence of corrosion. If unacceptable corrosion is discovered, additional examination and corrective action, including pipe replacement, is performed. 8.3 Saltwater Disposal Facility Inspection 112.9(d) (2) Inspect saltwater (oil field brine) disposal facilities often, particularly following a sudden change in atmospheric temperature, to detect possible system upsets capable of causing a discharge. This section is not applicable because this site is not a saltwater disposal facility. 8.4 Flowline Maintenance 112.9(d) (3) Have a program of flowline maintenance to prevent discharges from each flowline. Personnel view and informally inspect aboveground valves and piping several times per week as part of their routine maintenance schedule. Any deficiencies or equipment failures are reported to the field supervisor and corrected promptly. Aboveground valves and piping are formally inspected on an annual basis. These annual facility inspections are documented on the facility inspection form shown in Appendix D. Buried piping is not uncovered for inspections, but if uncovered for any reason, the piping and associated equipment is examined for evidence of corrosion. If unacceptable corrosion is discovered, additional examination and corrective action, including pipe replacement, is performed. SPCC Plan Page 13 9.0 REPAIR, ALTERATION, RECONSTRUCTION OR CHANGE IN SERVICE [112.7(i)] 112.7(i) If a field -constructed aboveground container undergoes a repair, alteration, reconstruction, or a change in service that might affect the risk of a discharge or failure due to brittle fracture or other catastrophe, or has discharged oil or failed due to brittle fracture failure or other catastrophe, evaluate the container for risk of discharge or failure due to brittle fracture or other catastrophe, and as necessary, take appropriate action. If an AST undergoes a repair, alteration, reconstruction, or change in service, it will be evaluated for the risk of discharge or failure due to brittle fracture or other catastrophe. Qualified contractors and personnel will perform all repair, alteration, and/or reconstruction activities according to accepted industry practices and regulations. 10.0 REGULATORY CONFORMANCE AND EXCLUSIONS [112.70)] 112.70) In addition to the minimal prevention standards listed under this section, include in your Plan a complete discussion of conformance with the applicable requirements and other effective discharge prevention and containment procedures listed in this part or any applicable more stringent State rules, regulations, and guidelines. 10.1 Regulatory Conformance The subject properties are not subject to any state -regulated discharge prevention and containment requirements beyond those specified by federal regulation. State notification procedures are included under the notification section. 10.2 Regulatory Exclusions The subject properties are classified as onshore production facilities which store only petroleum based oils. Furthermore, the properties are not expected to cause substantial harm to the environment as demonstrated by the completed Certification of Applicability of Substantial Harm Criteria form contained in Appendix G. As such, the subject properties are excluded from the following regulations: Subpart B - Requirements for Petroleum Oils and Non -Petroleum Oils except Animal Fats ... 40 CFR 117(g) Security (excluding production facilities) 40 CFR 117(h) Loading/unloading rack (site does not have loading/unloading RACK) 40 CFR 112.8 SPCC plan requirements for onshore facilities (excluding production) 40 CFR 112.10 SPCC plan requirements for onshore drilling & workover facilities 40 CFR 112.11 SPCC plan requirements for offshore oil facilities Subpart C - Requirements for Animal Fats and Oils, Greases, Fish and Marine Oils.... 40 CFR 112.12 SPCC plan requirements for onshore facilities (excluding production) 40 CFR 112.13 SPCC plan requirements for onshore oil production facilities 40 CFR 112.14 SPCC plan requirements for onshore oil drilling facilities 40 CFR 112.15 SPCC plan requirements for offshore oil drilling facilities SPCC Plan Page 14 Subpart D - Response Requirements 40 CFR 112.20 Facility response plans 40 CFR 112.21 Facility response training and drills/exercises SPCC Plan Page 15 APPENDIX A INDIVIDUAL SITE INFORMATION f4 rcitct{it To SPcc Puck SPCC Plan AC�R��DfX,6 APPENDIX B OIL SPILL CONTINGENCY PLANS AND WRITTEN COMMITMENT OF MANPOWER, EQUIPMENT, AND MATERIALS SPCC Plan BBC OIL SPILL CONTINGENCY PLANS AND WRITTEN COMMITMENT OF MANPOWER, EQUIPMENT, AND MATERIALS Secondary containment or diversionary structures are impracticable for portions of this facility for the following reasons (attach additional pages if necessary): All aboveground oil storage tanks at this facility are contained within diked areas. Secondary Containment for line treaters, separation units, oil loading areas, and underground flowlines may be impracticable at this facility for the following reasons: 1) All line treaters and separation vessels at newly constructed batteries are ASME coded flow- through process vessels and are NOT oil storage vessels. 2) Secondary containment diking around fired line treaters may represent a safety hazard 3) The most likely type release from line treaters or separation units is a pressure release from the "pop-off" valve discharging gas rather than crude oil. 4) A safe and effective dike system would be difficult to design and impracticable to construct for loading areas, line treaters, separation vessels, and flowlines. 5) Underground flowlines typically operate at much less than their rated pressure. 6) Extensive diking and/or drainage trenches would interfere with site access for normal operations and also with current surface land uses. Extensive diking and/or trenching may represent a physical hazard as well as an impediment to emergency response equipment and personnel. A spill contingency plan is in effect for this facility in the event of an oil spill. YES An oil spill contingency plan is attached. YES A written commitment of manpower is attached to the spill contingency plan. YES SPCC Plan Page B-1 BBC OIL SPILL CONTROL AND CONTINGENCY PLAN FORWARD Constant vigilance and a personal dedication to protection of the environment should be the goal of every BBC employee. Every safeguard should be taken to prevent the accidental discharge of oil to soil or water, and immediate response to oil spills is every employee's responsibility. Preventive action is our best measure to hold oil discharges to a minimum and reduce the potential pollution danger. The following contingency plan forms the basis to meet this challenge. This alert procedure becomes effective immediately upon the observance of or hearing of an oil spill from any company facilities. Any employee observing or receiving knowledge of an oil spill must immediately take actions to minimize injuries and damage and notify the designated person. Make sure all steps taken are in accordance with good safety practices. The priority in all circumstances will be to protect life. *********************************************** SPCC Plan Page B-2 BILL BARRETT CORP. OIL SPILL CONTROL AND CONTINGENCY PLAN PURPOSE Establish procedures to minimize damage caused by pollution from an accidental oil discharge. II. GENERAL A. Operating personnel will become familiar with these procedures and take corrective action in the event of an oil spill. B. As a preventive measure, be alert for and eliminate potential pollution hazards. III. RESPONSE PROCEDURES A. Upon detecting an oil spill, the person making the discovery should: 1. Determine the source of the leak. 2. Attempt to stop the source of the leak, if it can be done safely. 3. Notify the responsible person and the EH&S Dept. that an oil spill has occurred, and alert the foreman of corrective action taken or required. B. For minor spill events not endangering surface or ground water, the Production Foreman shall: 1. Contact the EH&S Dept. 2. Direct safe clean-up of the oil spill. 3. Arrange for necessary repairs. C. For major spills and spills which endanger surface or ground water, the Production Foreman shall: 1. Mobilize Environmental Emergency Response Equipment and Contractors 2. Contact the EH&S Dept. 3. Direct safe clean-up and arrange for additional equipment, material and manpower as needed. 4. Arrange for necessary repairs. D. Containment, Cleanup and Restoration The general procedures outlined below will normally be followed for spills in most areas. Only approach a spill if you are certain it is SAFE to do so. If you are not sure it is safe wait for additional personnel and/or equipment. 1. Land Oil Spill a. Construct earthen berms or shallow catchment pits with the appropriate equipment to contain the oil. b. Remove any free oil with absorbent materials or vacuum trucks c. Affected soils will either be treated or transported to an approved disposal facility. d. Dispose of all oil -soaked materials (e.g. hay, absorbent cloths or booms) in an approved manner. e. Restore the land area, as nearly as possible, to original conditions. 2. Surface Water Oil Spill SPCC Plan Page B-3 a. If possible, construct an earthen dam downstream of the oil spill (river or stream spills only). b. Allow water past the dam using an underflow pipe, if possible. c. If it is impractical to build an earthen dam, place an oil -absorbent boom downstream or outside of the extent of the oil spill area. d. If possible, construct a backstop downstream of the dam/boom using fence posts and some type of fencing material. Place a boom in the backstop to absorb residual traces of oil on the water surface. e. Remove any free oil from the water surface between the dam/boom and spill using absorbents or a vacuum truck. f. Physically clean the bank areas to prevent any residual oil from entering the water. g. Dispose of all oil -soaked materials (e.g. hay, absorbent cloths or booms) in an approved manner. h. Restore the land area, as nearly as possible, to original conditions. IV. MANPOWER AND EQUIPMENT AVAILABILITY A. Company Personnel In the event of an oil spill, all employees will be utilized as necessary for containment and clean- up. The company personnel used to respond to an oil spill at the site are identified in Appendix C. They will provide oversight in the containment, removal, and remediation of any spilled material. They will also assist and supervise in the maintenance of site security to insure only authorized persons are allowed within the site area during response operations. Company Equipment 1. Cars and pickup trucks equipped with mobile telephones are available for transportation and communications. 2. Pickups are equipped with shovels and hand tools for use in minor spills.

These inspections are not typically documented. Generally, drainage from containment structures is not conducted. Minor accumulations of precipitation are allowed to evaporate. Large accumulations of fluids may be removed by vacuum truck and either returned to a separation vessel for processing or transported to a permitted recovery/disposal facility. In the unlikely event that drainage events are conducted, the accumulated stormwater is visually inspected for contamination from oil. NO oil is released from or pumped from within the berm onto the ground or into a water course. Drainage or pumping does not occur until the fluids have been inspected for oil. Draining only occurs with constant visual supervision of the drain outlet, and only after determining that the water is indeed fresh. Draining ceases at the first sign of an oil sheen and the remaining fluid is removed and properly treated or disposed. The foreman in charge of the facility operations is consulted before any berm is drained or purged. As required by law, any time that stormwater is discharged from the dike, a record of the inspection, discharge and oil removal is to be maintained. The following is the discharge record: Date of Discharge Oil Sheen Present Inspector's Signature Comments SPCC Plan APPENDIX A INDIVIDUAL SITE INFORMATION SPCC Plan A.1.

WestWater biologists previously prepared two reports entitled "East Lateral Loop Pipeline & Bailey Compressor Station Integrated Vegetation & Noxious Weed Management Report" and "East Lateral Loop Pipeline & Bailey Compressor Station Wildlife Assessment and Management Report" in October, 2007. WestWater biologists routinely perform surveys for sensitive plant species while performing other biological surveys for a proposed project. However, unless specifically requested to provide a report concerning the issue of interest, in this case sensitive plants, the reports do not include details on survey findings. For the purposes of this letter report, sensitive species are considered to be those included on the Endangered Species Act (ESA) list and ones recognized as sensitive by BLM. No ESA listed plants have been previously found in the project area vicinity, and no habitat for such species is believed to be present. No ESA listed plants were observed during WestWater's surveys. BLM sensitive plant species potentially present in the vicinity of the proposed pipeline and compressor station are: (1) Penstemon harringtoni (Harrington's beardtongue) (2) Astragalus debequaeus (DeBeque milkvetch), and (3) Astragalus naturitensis (Naturita milkvetch). A brief description of typical habitat for these species in the project area follows. (1) Harrington's beardtongue habitat is sagebrush at 6400 feet elevation and higher. Sagebrush covers the compressor site which reaches 5930 feet elevation at its upper end. This site was searched on September 24, 2007. At this date a plant as robust as P. harringtonii would have been visible, although in a dried state. No penstemon plants were detected. 1 (2) DeBeque milkvetch grows on fine textured soil in and around pinyon juniper woodlands at elevations common to the project. The plant has not been found east of Rifle, Colorado and was not observed during project surveys. (3) Naturita milkvetch is found on shallow soils over rock outcrop terrain in and around pinyon juniper woodlands at elevations within the range of those of the project. This plant also has not been found east of Rifle, and was not observed during project surveys. The above information was corroborated with the Colorado Natural Heritage Program database and the experience of WestWater biologists in the project area. In summary, our analysis leads us to conclude that there are no sensitive plant issues with the existing BBC well sites or the East Lateral Loop Pipeline and Bailey Compressor Station project. There is no evidence that any of these species are likely present along the proposed pipeline or on the proposed compressor site. Please feel free to contact our office with any questions concerning these reports or if we can be of service in any way. Sincerely, Principal Environment Scientist 2 Grand River Institute 4- P.O.

The areas of construction activity are in T. 6 S., R. 91 W. Sections 29, 30, and 31; and, T. 6 S., R. 92 W. Sections 22, 23, 26, and 27; 6th P.M. The new pipeline will follow an existing corridor in which two pipelines have been previously constructed, and will generally cross agricultural lands that have also been surface disturbed. A files search of the general area was conducted through the Colorado Historical Society's Compass Website. Fourteen cultural resources survey projects have been completed in the immediate vicinity of the proposed pipeline with the result of the recording of only two sites. Both sites occur within about 0.5 mile of the proposed project area; however, they are over 0.25 mile from the impact area and will not be directly affected. Of the two, 5GF251 (a prehistoric open camp) has been evaluated as not eligible, and 5GF304 ( a prehistoric rock art site) has been field evaluated as eligible for listing on the National Register of Historic Places. Based on these findings, the occurrence of additional significant cultural resources in the impact area of the proposed new pipeline is considered low. A list of the projects that have been completed within about 0.5 mile of the proposed pipeline is attached. Please call me if you have any questions or need additional information. Sincerely, Carl E.

The Development Plan is for the construction of the Bailey Compressor Pipeline, located entirely within Garfield County. This initial information gathering is in response to Garfield County regulation 9.07, Development Plan Review for Pipelines, specifically 9.07.04(10) Sensitive Area Study. BBC requested that O&G conduct file surveys and make informal contact with appropriate agencies to ascertain if there are sensitive area issues along the proposed pipeline route not previously mitigated or identified. Although the Bailey Compressor Pipeline is entirely on private land, it is planned adjacent to some federal/ BLM lands. As a courtesy and as a source of the most accurate and recent information concerning federal and state endangered species and sensitive resources, O&G informally consulted with BLM and USFWS staff biologist. Section 10, of the County Regulations requires addressing the following information in the Development Plan. "List the types and an -as of concern along the pipeline right-of-way, such as; sensitive plant populations, cultural, archeological, paleontological resources and wetlands identified during pre -construction environmental surveys, if applicable." Information provided herein is based on file searches, the route map provided by BBC and inforrnal consultation with BLM and USFWS specialist. Exact and formal consultation would require on -ground site surveys by qualified biologist. Areas of Concern: Following information reviewed and inforrnal consultation with the USFWS and BLM Resource Specialist, indications are that there are no areas of concern along the proposed route. The route crosses pinon-juniper areas dominated by upland grasslands, all on private land. 420, { 4r i 11 Inverness Way South • Englewood, Colorado 80112 tel 720-529-9777 • fax 720-529-9798 • www.ogenvironmental,com Sensitive Plant Populations: Based on discussions and with the USFWS Biologist Creed Clayton, who has knowledge of the area and is responsible for USFWS (and DOW) consultation for the Glenwood Springs BLM Energy Office, indicated that he was not aware of sensitive plant population issues along the proposed route. He did request that if endangered species were encountered, that the USFWS would be consulted as a courtesy. Mammal and Raptor Species: Consultation with federal resource specialist indicates that the habitat associated with the pipeline is conducive to the Lynx; however there have been no sightings in that specific area. USFWS request that raptor nest not be disturbed or destroyed during pipeline construction. BBC indicated that they would be employing best management practices and voluntary contact the USFWS if these situations occur. Cultural, Archeological, and Paleontological Resources: Bill Barrett Corporation has indicated that all aspects of cultural resources compliance have been addressed. Wetlands: Project and National Wetland Inventory Maps do not indicate the specific presence or identification of wetlands along the project route; however this can only be verified by site inspection. According to BBC, it is their intent to bore under all potential jurisdictional wetlands. O&G consulted with BLM Biologist, Creed Clayton, Glenwood Springs Energy Office, and Rick Kruger, USFWS, Grand Junction, concerning all area of concern issues, including endangered species and Colorado River endangered fish species. There does not appear to be critical issues or areas of concern associated with the proceeding of this project, according to conversations with both Glenwood and Grand Junction BLM/USFWS field offices.

East Lateral Loop Pipeline & Bailey Compressor Station Integrated Vegetation & Noxious Weed Management Report Garfield County, Colorado Compressor Station Site with big sagebrush the dominant plant cover Prepared for: Bill Barrett Corporation, Inc. Prepared by: WestWater Engineering (In Cooperation with Wagon Wheel Consulting, Inc.) October 2007 INTRODUCTION A field inspection of the proposed compressor station site and pipeline route was conducted by WestWater Engineering (WWE) biologists on September 24, 2007. The site map is shown in Figure 1. The inspection focused on noxious weeds and biologically sensitive areas and wildlife. This integrated vegetation and noxious weed management plan, required by Garfield County Regulation 9.07.04 (13) (Board of County Commissioners 2006), uses the data obtained. LANDSCAPE SETTING The Barrett East Lateral Loop proposed compressor station site is located in Section 22, SE1/4 SE 1/4, T6S, R92W, 6th PM (Figure 1 - Map). The Colorado River at the town of Silt, Colorado, is approximately 2.5 miles to the north. The 7 ± acre site is located on a gentle north sloping Sagebrush Park, which is next to pinon pine -Utah juniper woodland to the east. The proposed alignment of the associated pipeline follows an existing pipeline southeastward, turning east and then northeasterly to end 3.1 miles to the east of the compressor station, involving eight sections. The entire project lies on fee -simple properties. Bailey's ecoregional map (Chapman et al. 2006) shows the project in the Colorado Plateau's Shale Deserts and Sedimentary Basins Ecoregion. The soils derive from sandstones, shale, and basalt. The U.S. Natural Resources Conservation Service classifies the rangeland ecological site on the proposed compressor site and over most of the pipeline route, as a Rolling Loam (loamy soils on a rolling landscape) (NRCS 2007a). FINDINGS The noxious weeds list of Garfield County plus the State noxious weed list formed the search list (Table 1). These lists can be found online at www.garfield-county.com/Index.aspx?page=607 and at www.colorado.gov/cs/Satel lite?c=Page&cid=1174084048733&pagename=Agriculture- Main%2FCDAGLayout. Figure 1 depicts weed locations found within and adjacent to the project site/route. Table 2 records the weed findings at the compressor station site and along the pipeline route. All the weed species found in this inspection occurred in the area before the recent oil and gas development activity, due to the area's long history of an agricultural, pastoral economy. The majority of the weeds were found along roads. The roads built or used most recently by petroleum development activities tend to encourage weeds, in particular, Russian knapweed; Acroptilon repens (Figure 2). Roadsides with long-established vegetation tend to have lesser amounts of noxious weeds. Chicory, Cichorium intybus, is a notable exception commonly established along old roadways (Figure 3). The difference in those two species may be due to the more recent immigration of Russian knapweed, rather than any lack of ability to compete with other plants and persist. WestWater Engineering Page 1 of 13 pages October 2007 Simplified Control Method Recommendations Grasses compete well. Re -seed with aggressive grasses, if appearing in ROW, apply herbicide prior to flowering. Re -seed with aggressive grasses, remove at flowering or early seed, or apply herbicides at pre -bud or rosette stage. Re -seed with aggressive grasses; apply herbicides between rosette and pre- 1 bud stages. Till or hand grub in the rosette stage, mow at bolting or early flowering; apply seed head & rosette weevils, leaf feeding beetles, and/or herbicides in rosette stage. The least aggressive thistle, prevent from flowering by tillage, hand grubbing, or mowing. Apply herbicides pre -flowering. Hand grubbing may be sufficient since there are only a few localized plants currently. 1 Apply herbicide prior to flowering, Re -seeding disturbed sites with fast growing grasses. The most difficult thistle to control. Re -seeding disturbed sites with fast growing grasses, herbicide in fall (Curtail recommended), allelopathic —tillage & repeated applications may be necessary.

A bull thistle leaf has a lanceolate apex DISCUSSION and PLANNED ACTIONS Weed Control Prior to ground disturbing activities, the weeds found along the right-of-way (ROW) should be treated with an herbicide appropriate for the species at the most effective time for the majority of the species. Herbicide treatment with two or more physiological modes of action in spring and fall (fall = after approximately August 15, when natural precipitation is present) is the best method to control difficult species such as Russian knapweed (Boerboom 1999, Sullivan 2004). 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. Because noxious weed species occur along the proposed East Lateral Loop route from end to end, even though generally in low amounts, the potential for these weeds to spread during and following the construction phase of the project is high. Standard operating procedure should be to keep soil disturbing activities to the minimum level possible. Construction vehicles should park on previously disturbed lands. Temporary fencing may be needed in places to confine vehicular activities. To the extent practical, frequently clean vehicles to prevent the spread of weed seeds being carried from place to place. Segregating topsoil (0-4 inches rocky soils, 0-16 inches rock -free soils), to be returned to original location in the standard method as the project proceeds, works well to allow native plants to rapidly return to the site. State -of -the -industry techniques will best control water drainage to reduce erosion. Erosion blankets, barriers, and wattles should be of biodegradable materials. Reused materials should only come from weed -free areas. WestWater Engineering Page 7 of 13 pages October 2007 The following tables summarize the most effective treatment strategies for noxious weeds, depending upon their growth habits. Table 3 includes annuals and biennials and Table 4 shows strategies for perennial weeds. 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. 2. Chop roots 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 may not prevent flowering. 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. 2. Herbicide treatment at bud to bloom stage or in the fall. 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. 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 the fall 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 may be reduced, however. 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 biology (Hartzler 2006, Sirota 2004). Re -vegetation The proposed compressor station would constitute the largest disturbance to natural vegetation because the site has native big sagebrush; Artemisia tridentata wyomingensis (see Cover Photo). The proposed pipeline route is along an existing ROW and would re -disturb vegetation in a lower successional state. The fact that the ROW rehabilitation was successful over most of the alignment (Figure 8), suggests that returning it to its current condition is a reasonable expectation. The compressor station would likely be a long-term facility. The possibility of returning the site to sagebrush cover after site closure is less certain. The most valuable sagebrush in this area should average greater than 18 inches high with a canopy cover value greater than 18 percent, occupying stands larger than 18 acres (the "Rule of Eighteens"). Much of the sagebrush in the basin south of Silt has one or all three of these values less than this. Mitigation for lost acreage of sagebrush lands could be done, where appropriate. Two approaches for mitigation are proposed. They are 1) establish sagebrush and similarly -sized native shrub patches in those portions of the ROW distant (>250 m) from any live sagebrush or rabbitbrush plants (Attachment A) and 2) treat ROW sagebrush that can be avoided by project WestWater Engineering Page 8 of 13 pages October 2007 Figure 8. Pipeline rehabilitation shows successful establishment of seeded grass species in the mid-ground, yet poor establishment in the foreground, October 2, 2007 construction crews to improve them. Mowing or disking sagebrush, formerly a popular treatment, would not be done. Biologists now recognize that young sagebrush plants are of less value to wildlife than mature plants (Welch 2005). Inter-seeding desirable forb and grass species into sagebrush stands that have a degraded understory is a new and promising practice. Table 5 provides a seed mix formula that can be used in an inter-seeding project. Because achieving germination of sagebrush seeding is less reliable than achieving it with native grasses, most of the disturbed area would use a seed mix purely of native grasses. Forbs would not be seeded due to the difficulty of establishing desirable forbs before undesirable weeds invade. Also, broadleaf herbicides can safely be used to remove any of the noxious weed species on the Garfield County list from a seeding that only includes grasses. Non-native species should not be in the seed mixes because they retard the return to a natural plant cover (CNHP 1998). Pinon juniper woodland (PJ) is, likewise, much reduced in this basin. The ratio of deer and elk foraging area (sagebrush, pasture, crop land) to cover area (PJ) is excessively high. Therefore, no reduction in PJ to expand sagebrush is recommended. There are four areas of moist soils along the proposed pipeline route: Divide Creek, two small drainages, and a ditch line east of Garfield County Road 311. Divide Creek, at the proposed crossing in Section 25 (SE1/4, SW1/4, T6S, R92W) is incised, putting the floodplain water table too low to support emergent vegetation such as sedges. The water regime does support riparian vegetation, thus, floodplain-adapted grasses should be seeded for rapid restoration of desirable perennial ground cover. The seed formula in Table 5 includes moist soil species. WestWater Engineering Page 9 of 13 pages October 2007 Table 5.

Prepared by: WestWater Engineering Inc. (In coordination with Wagon Wheel Consulting, Inc.) October 2007 INTRODUCTION The proposed Barrett East Lateral Loop Pipeline and Bailey Compressor Station site is located in Section 22, SE1/4 SE 1/4, T6S, R92W, 6th PM (Figure 1). The Colorado River at the town of Silt, Colorado, is approximately 2.5 miles to the north. The 7± acre compressor station site is located on a gentle north sloping big sagebrush park next to piflon pine -Utah juniper woodland to the east. The proposed route of the associated pipeline follows an existing pipeline route southeastward, turning east and then northeasterly to end 3.1 miles to the east of the compressor station. The entire project lies on fee -simple properties. Bailey's ecoregional map (Chapman et al. 2006) shows the project in the Colorado Plateau's Shale Deserts and Sedimentary Basins Ecoregion. The soils derive from sandstones, shale, and basalt. The Natural Resources Conservation Service classifies the rangeland ecological site on the proposed compressor site and over most of the pipeline route as a Rolling Loam (loamy soils on a rolling landscape). WestWater Engineering (W WE) conducted a site and route inspection on September 24, 2007. The lands were surveyed for plant community conditions, listed noxious weeds, and wildlife. This document covers those matters that relate to wildlife. The species discussed are a fraction of the total, yet represent the major wildlife concerns of the area. This assessment and mitigation plan meets the wildlife requirement of Garfield County Regulation 9.07.04 (10) (Board of County Commissioners 2006). RESULTS Big Game Colorado Division of Wildlife (CDOW) places the area within Game Management Unit 42. Mule deer and elk severe winter range overlays the project area entirely. CDOW defines severe winter range to be where 90 percent of a species of wildlife are concentrated during the worst two winters in ten. Every winter both deer and elk concentrate in the project area. In the project area, elk (wapiti) are as common, or more common, than mule deer according to pellet group abundance (Figure 2). Apparently, elk have adapted to higher densities of roads in the area than is typical elsewhere (Lyon 1983). The sagebrush generally shows extreme hedging from big game browsing (Figure 3). This suggests that a shortage of sagebrush is a limiting factor in big game winter range carrying capacity. The piflon pine -Utah juniper woodlands on steeper, rockier slopes provide escape and loafing cover for deer and elk. Black bears typically center their summer activities in the aspen zone and move into the mountain shrub zone in mid August to fatten up for winter hibernation. This is typical, but bears exhibit atypical behavior and do it frequently when mast crops fail in their usual range. This means that bears may pass through the Bailey Compressor Station site. Bears will be drawn to human food in any form, garbage or otherwise. The maxim cannot be overused, that "a fed bear is a dead bear". It is highly recommended that food storage and garbage removal be done in a timely and secure manner so as to not habituate bears to a human facility.

Birds Species encountered through casual observation during the multiple -objective survey are shown in Table 1 below: Table 1. Species Encountered During the Survey Red-tailed Hawk American Kestrel Wilson's Snipe Mourning Dove Northern (Red -shafted) Flicker Piton Jay Western Scrub Jay Mountain Chickadee Juniper Titmouse White -breasted Nuthatch Mountain Bluebird Yellow-rumped (Audubon's) Warbler Chipping Sparrow Song Sparrow White -crowned Sparrow Western Meadowlark House Finch Cassin's Finch Pine Siskin American Goldfinch Black -billed Magpie Savannah Sparrow Note: bold indicates a U.S. Fish and Wildlife Services Species of Conservation Concern & italics indicate species migrating and/or has no nesting habitat in the area. Birds of Conservation Concern are known to inhabit the area. These include northern harrier, golden eagle, loggerhead shrike, pifion jay, Bewick's wren, black -throated gray warbler, and Brewer's sparrow. Only the Brewer's sparrow has a potential for nesting and/or significant foraging within any habitat of the type that would be affected by the project. WestWater Engineering Page 3 of 9 pages October 2007 Considering the current condition of the sagebrush on the compressor site, and generally in the area, it isn't likely that Brewer's sparrows occupy any of the habitats that would be further degraded or destroyed by the proposed action. Several raptors reside or pass through the basin south of Silt. Kim Potter (U.S. Forest Service biologist, Rifle, Colorado, pers. comm.) reports nesting red-tailed hawks, American kestrels, and long-eared owl in the basin. Strong evidence exists for great horned owls, Cooper's hawks, and northern saw -whet owls also nesting in the area. Swainson's and sharp -shinned hawks may nest in the area as well. Reports suggest that barn owls and western screech owls have expanded their ranges into the area almost certainly due to the recent stretch of mild winters (K. Potter pers. comm.). Northern pygmy owls, northern goshawks, rough -legged hawks, merlins, and bald eagles winter in the basin. The mourning dove is the common game bird in the area (Righter et al. 2004). Weedy plants that usually invade after an area is disturbed provide food for mourning doves plus several nongame birds, especially finches. Several of these "weed" species can actually be desirable in that they fill in where a rehabilitation seeding fails to establish. By filling in these areas, innocuous weedy plants help suppress noxious weeds, while feeding a list of wildlife species. Examples are common sunflower (Helianthus annuus), stork's bill (Erodium cicutarium), kochia (Bassia scoparia), and Russian thistle (Salsola kali). Canada goose, mallard, and other waterfowl, plus American coot, may nest or forage in the right-of-way (ROW) near the pond in Section 26 (T6S, R92W) and along Divide Creek and the draws east of the creek. The livestock culture attracts wild turkeys out of the mountain shrub and Douglas fir habitat, south and east of the area. Other Wildlife Widely distributed game species (small game, furbearers) include rock squirrel, mountain cottontail, red fox and coyote; and along Divide Creek, beaver and mink. In addition to the birds mentioned above, other non -game wildlife that characterize the area are Hopi chipmunk, Woodhouse toad, northern leopard frog, western terrestrial garter snake, and various commonly detected invertebrates, such as alfalfa and monarch butterflies. Speckled dace, fathead minnow, creek and roundtail chubs, flannelmouth and white suckers, and possibly bluehead sucker swim in Divide Creek. The frog and chub are Colorado State Species of Special Concern. Attachment 1 lists the wildlife species mentioned in this text. PLANNED WILDLIFE MEASURES AND RATIONALE Because the site is on native big sagebrush dominated ground, the proposed compressor station would constitute the largest disturbance to natural vegetation (Figure 4). The proposed pipeline route is along an existing ROW and would re -disturb vegetation in a lower successional state. The fact that the ROW rehabilitation was successful over most of the route (Figure 5), suggests that returning it to its current condition is a reasonable expectation. Because the compressor station site would likely be occupied for a long time period, the possibility of returning it to sagebrush cover after site closure is less certain. WestWater Engineering Page 4 of 9 pages October 2007 Figure 4. Wyoming sagebrush park at the proposed Bailey Compressor Station site (note that elk sign is abundant). The site is in a big game winter concentration area, Garfield County, Colorado, October 2, 2007 Figure 5. Pipeline rehabilitation shows successful establishment of seeded grass species in the mid -ground, yet poor establishment in the foreground, Garfield County, Colorado, October 2, 2007 WestWater Engineering Page 5 of 9 pages October 2007 The most valuable sagebrush in this area should average greater than 18 inches high with a canopy cover value greater than 18 percent, occupying stands larger than 18 acres (the "Rule of Eighteens"). One or all three of the values in much of the sagebrush in the basin south of Silt are less than this number. Mitigation for lost acreage of sagebrush lands should be pursued if feasible. Inter -seeding desirable forb and grass species into sagebrush stands with a degraded understory is a new and promising practice. Mowing or disking sagebrush is clearly not recommended here. Young sagebrush plants are of less value to wildlife than mature plants. Pinon juniper woodland (PJ) is, likewise, much reduced in this basin. The deer and elk foraging area (sagebrush, pasture, cropland) to cover area (PJ) ratio is excessively high. Therefore, no reduction in PJ to expand sagebrush is recommended. (See the Integrated Vegetation and Noxious Weed Management Plan for the East Lateral Loop Project for specific vegetation treatment and management plans.) The stream crossing of Divide Creek requires a "404 Permit" from the U.S. Army Corps of Engineers (COE). Whether the project will qualify for the "Nationwide Permit under #12 Utility Activities" will have to be determined, e.g., the disturbance < 0.5 acre and < 500 ft long. To be safe Barrett Corporation should notify the COE district engineer early in the planning stages to simplify meeting any permit conditions. Whatever the type of 404 Permit this project will operate under, it will contain stipulations for reducing the adverse effects of redistributing stream bed material while making a pipeline crossing of the stream. Sedimentation of spawning gravels could be a contributing cause of the decline of bluehead and flannelmouth suckers throughout their ranges (Ptacek et al. 2005). Spawning requirements of the state species of special concern, roundtail chub, are not known (Rees et al. 2005). The development of the basin south of Silt by the petroleum industry undoubtedly has had and will have increasing adverse effects on raptors, as with most other native wildlife species. However, the effect of this one project on wintering raptors would not be measurable. Conversely, impacts may well arise and be detectable during raptor nesting seasons. A raptor survey in the spring of 2008 would provide the information needed to prevent nesting impacts. Late April and early May is the optimum time to survey the area for nesting raptors. Since most of the likely habitat is evergreen PJ woodland (Figure 6), observing nests would be difficult without eliciting responses from nesting birds by using recorded call playback techniques. Two visits should be adequate to survey the project route, a single day for diurnal raptors and one night for owls. Suspending construction activities within a quarter mile of active nest sites is a positive conservation action for raptors. Obscuring terrain may allow a closer approach to an active nest. For great horned owls and American kestrels, merely avoiding the nest is sufficient. For the other owls and hawks the quarter mile buffer applies and the period from March 15 to July 15 is the sensitive time. The standard period for avoiding disturbance to golden eagles is February 15 to July 15. Construction should be scheduled around seasonally sensitive times to the extent possible. This may be difficult. On public lands the acceptable work window may only be four months. Such a period could start as late as August 1 (end of stipulated migratory bird nesting season) and end December 1 (start of critical big game winter period). In the project area these four months, August through November, are the optimum work months considering wildlife. If brushing out WestWater Engineering Page 6 of 9 pages October 2007 Figure 6.

Likewise, wildlife would benefit if the peak of construction activity can avoid the critical time for deer and elk, December 1 to April 30. If the Divide Creek crossing can avoid May through July, the fish spawning period would be protected. Table 2 displays the most critical periods for wildlife in the East Lateral Loop project area. As the project advances, and if flexibility becomes urgent, it may be necessary to exercise calculated flexibility to accomplish the work. In this case, the April 30 ending of the critical winter range period can, in most years, retract two weeks to April 15 with fewer adverse effects than can the migratory bird period be pushed to June 1. Also raptor nesting is more critical in the first half of the season when nests are most likely to be abandoned due to disturbance (Richardson and Miller 1997). Table 2. Seasonal limitations on construction work in the area of East Lateral Loop Project Concern Period Deer and Elk severe (critical) winter range December 1 — April 30 Migratory Birds primary nesting season May 15 — July 15 Golden Eagle nesting February 15 — July 15 (1/4 mile of nest only) Hawks and Owls nesting March 15 — July 15 (1/4 mile of nest only) Native fish spawning May 1 — July 31 (Divide Creek only) Ideal construction periods May 1 —15, July 16 —November 30 Compressor noise should be attenuated to the extent practical. While many species of wildlife adapt to noise, there is a cost in failed detection and responses to natural sounds. There may also be physiological deterioration (reduced fitness) due to increased metabolism, increased heart rate, decreased auditory function, and other effects (Bromley 1985). Tolerance to noise rather than avoidance by wildlife has resulted in significantly reduced productivity (Ingelfinger 2001, Stone 2000, DOE 2001, Whittacker and Knight 1998). The goal for noise containment is <-60 dB at 200 m in any direction from the compressor station pad. Construction and service vehicle drivers should be encouraged to maintain modest speeds to reduce the chances of striking wildlife on the road. Speed limit signs can be posted on company - maintained roads where collisions with wildlife appear most likely. WestWater Engineering Page 7 of 9 pages October 2007 Power lines, tall towers, vertical exhaust stacks, reserve pits and fences constitute potential wildlife hazards that may accompany the project. If, or when, any potential hazard becomes a feature of the project, it should be designed with standard wildlife safe elements following consultation with specialists such as those at WWE.

H2S Contingency Plan (if applicable) IX. General Telephone Numbers X. Area Specific Telephone Numbers -Including Hospital and Emergency responders I. Introduction Serious incident situations, unless properly controlled, can result in loss of life and damage to public or private property. Situations resulting from spills can generate complex technical, legal and public relations problems. It cannot be overemphasized that the best way to handle emergency situations is to prevent their occurrence. This Plan is designed to help Bill Barrett Corporation (BBC) respond quickly and effectively to the problems presented by serious incidents when they do occur. The Plan's primary goal is to help the company prevent, as far as practical, any loss of life or damage to property, wildlife, or the ecology. Within this Response Plan you will find descriptions of the duties that must be accomplished when a serious incident occurs. It provides personnel with procedures for handling such incidents effectively. The Plan is prepared: 1. To serve as the basis for an organized action plan in dealing with emergencies and spills of all magnitudes. 2. To spell out responsibility, priority and importance in countering an emergency situation or major spill. 3. To provide information on the means of handling serious incidents and identify the organizations that are involved. 4. To tabulate the personnel and agencies that must be notified. Prompt action is mandatory. For this reason, the content of this Plan must be understood by the persons who may have need of it. All involved employees should be informed to take quick action to protect life and property and to immediately report the incident. The plan will require modification from time to time, as personnel change, as technologies advance, and as experience indicates improvements. The plan is to be reviewed annually by the EH&S staff to assure that it is up to date. This plan is not intended to replace existing SPCC or other required Plans, but rather its purpose is to be a supplement providing general guidelines for emergency situations.

Communication / Evidence It is important when an emergency is identified that notification to an employee's supervisor is made as soon as possible. It is mandatory that notices be given internally as soon as practical. Notification will follow the reporting hierarchy for BBC. The first person to identify the emergency will report it to his/her supervisor. If a person's supervisor cannot be immediately reached with the known contact (i.e. telephone numbers of home, office, portable phone, or pager) then the next person on the list must be notified. At each notification, instructions may be received to be implemented. Each person receiving notification then is responsible for contacting up the chain of command. Notification to regulatory authorities should be made only after discussion the situation with the Senior onsite BBC Supervisor. Communication Techniques 1. Communication must be through a two-way confirmed means. Use of messages on a voice recorder or answering machine does not constitute notification. A message may be left, but the next person up the chain of command must be contacted. 2. If a line is busy, advise the operator that you have an emergency and get the operator to interrupt the line. 3. Make sure the person you are communicating with understands you. This can be done by asking them to repeat key parts of your discussion. 4. If you are calling someone you do not frequently talk to, make sure you identify yourself and where you can be reached. 5. If working with a radio communication, call out the person you want to talk to followed by your name (E.G. "Kurt, this is Greg, do you read meT) Wait long enough for a response. The person may be away from the radio and may need some time to get back, 6. If calling by telephone, let the phone ring at least six times before hanging up. 7. Do not hesitate to call above your supervisor if your supervisor is unreachable. 8. Have relevant information available before starting notification. This does not mean a complete report of everything, but as a minimum the following: A. Location or facility and call back phone number B. Type of emergency. C. Time and date first noticed. D. Magnitude of emergency (e.g. size of fire or spill, number of people involved, injuries, if other properties or companies are involved). E. What you have done prior to making your notification. F. What your plans are in responding to the emergency. G. What are the weather conditions? H. What, if any, outside notifications have been made. I. What assistance you need. J. When you will call back with a subsequent report. Communication Equipment The primary means of communications will be by telephone and radio. Field operations that are Company operated will utilize two-way radio(s) communications and/or mobile telephones. Communications are designed to allow supervisors to be in contact with the Region office. Drillings rigs are usually equipped with either radio systems that communicate with the drilling contractor or mobile telephones. All drilling locations will have some means of two-way communications either onsite or within a 15 -minute drive (all types of weather). Community/Public Affairs Communication and public affairs are best handled by persons trained in dealing with the media. There will be times when it is not practical to refer all questions from the media and public to our headquarters. Indeed, a factual, short response can help reduce the time and effort ultimately needed to respond to the media and public. The senior ranking BBC onsite employee or his/her designate, if approached for a statement, may respond to questions from the media. The response should be a short statement of the facts. Estimates or speculations as to cause or size of the problem must not be made. Information requests for more than the facts relating directly to the immediate emergency (such as our future plans, amount of damage, what other hazards might exist, previous inspections done at the facility, any citations we may have received, etc.) should be referred to Jim Felton (or other designated personnel). If you are going to be questioned in front of a camera, consider your appearance and what will be in the background (behind you) of your interview. If possible, your interview should be done with a neutral or non -threatening background. It must be emphasized to provide only the facts. Assume any camera or recorder in the area is ON at all times (it just may be). Encourage the media to speak with Jim Felton in the Denver office for any detailed information. Preserving the Evidence In the aftermath of a serious incident, it becomes necessary to investigate the incident in order to determine cause and corrective actions. Perhaps the most important aspect of this investigation is determining the facts, and as such, the preservation of the evidence is of great importance. With the assistance of personnel involved at the incident scene, the evidence can be preserved and a more beneficial investigation performed. The following are basic guidelines which should be followed: 1. Secure the Area Rope off or other control access into the incident site. Access by non - company personnel allowed only after management approval. The only exception being necessary access by emergency medical rescuers and fire fighters. 2. Preserve the Evidence As much as possible, don't disturb objects relating to the incident. If unavoidable, stake or mark its location and record what was there. Never allow evidence to leave the scene with out approval. 3. Document the Evidence The IncidentLeader is responsible for preserving all documentation until the investigator(s) arrive at the scene. 4. Identify Witnesses If persons who witnessed the incident cannot remain on the scene to be interviewed during the investigation, get their names and pertinent information so that they can be located later. VII. HAZWOPER INDEX • Introduction • HAZWOPER Plan Narrative A. Pre -Emergency Planning B. Personnel Roles and Line of Authority C. Evacuation, Safe Distances, and Places of Refuge D. Employee Safety During a Hazwoper Response E. Response Evaluation & Follow -Up HAZWOPER Introduction HAZWOPER stands for "Hazardous Waste Operations and Emergency Response". HAZWOPER is a regulation designed to establish a management plan for emergencies involving hazardous materials. It is applicable to oil field operations primarily through the regulations addressing emergency responses to hazardous substance releases. HAZWOPER defines an emergency response, or responding to emergencies, as a response effort by employees from outside the immediate release area or by other designated responders (e.g., local fire departments, mutual -aid groups, designated HAZMAT Team, etc.) to an occurrence which results or potentially results in an uncontrolled release of a hazardous substance. For the purposes of this plan, the term "immediate release area" has been defined as encompassing the Superintendent's/Area Foreman's geographical area; therefore, if an emergency situation can be mitigated by Kerr-McGee Company personnel, it is not a HAZWOPER Emergency. In the event that an uncontrolled release requires the response of specially trained emergency teams to stop or control the release (e.g. Fire Department, Department of Health Services, etc.), it is a HAZWOPER response and the procedures in this section of the "Response Manual" must be followed. HAZWOPER Plan Narrative A. Preplanning Response Actions Preplanning is the key to a successful emergency management plan. Planning is handled through the training of company employees, formulation of emergency response activities, and pre -planned coordination with outside emergency responders. The following items constitute BBC's preplanning actions. All employees will be trained in Hazard Communication and Emergency Response. This includes hazardous material container labeling, access to, and understanding Material Safety Data sheets, and responding to emergencies involving hazardous materials. Specific emergency scenarios and appropriate responses will be discussed in these training sessions. All field employees will receive training to a minimum of "First Responder Operations Level", as defined by HAZWOPER. In the event of a HAZWOPER emergency, response activities will be coordinated with contract companies trained to respond to HAZWOPER. The names of these companies and their emergency numbers can be found in Section 9 and 10 of this Emergency Management Plan. B. Personnel Roles and Lines of Authority If an incident is classified as a HAZWOPER response, the Superintendent/ Area Foreman responsible for the facility requiring the response shall supervise BBC personnel in emergency response activities and perform all reporting requirements pursuant to this Emergency Response Plan. He/she will continue to perform these duties until such time as the responding Emergency Response Team arrives. Upon the arrival of the trained Emergency Response Team, the ranking official of said team will be designated as the Incident Leader. After that point, all emergency response activities will be conducted under the direction of the Incident Leader. C. Evacuation, Safe Distances, and Places of Refuge Evacuation - The open air nature of oil and gas operations generally permits numerous safe evacuation routes. In areas where this is not the case, employees are directed to attempt escape along a route that takes them upwind of an incident. Crosswind escape is suggested only until upwind escape is appropriate. Wind direction indicators are installed on all properties that contain H2S gas. Safe Distances - Prior to the arrival of the Incident Leader mentioned in Section B, the Superintendent/Area Foreman or designee shall be responsible for establishing the distance from the hazardous scene. After the Incident Leader arrives on the scene, safe distances will be established at his/her discretion. Places of Refuge should be established as appropriate for BBC operations. D. Employee Safety During a HAZWOPER Response All field employees will be trained to a minimum of "First Responder Operations Level". This training insures that the employee can operate certain equipment on the property during an emergency in order to bring the emergency condition under control. In the course of these operations the employee may be exposed to a hazardous environment, become injured, or have his/her clothing become contaminated with a hazardous material. The following items will address these issues. Personal Protection Equipment (PPE) is available to every employee. The type of equipment available to the employee will vary depending on the hazards inherent in the subject work area. Selection, safe use, limitations, maintenance, care and storage will be thoroughly covered in employee training. The Company's policies and procedures pertaining to PPE are found in the EH&S Manual located in each area office. Employee training will include provisions for initial and periodic refresher training. Emergency Medical Services will be provided by local hospitals, urgent care centers, and fire departments. Services have been identified in Section 10 of this Emergency Response Plan and are listed by BBC operating area name. Decontamination of clothing equipment will be coordinated with BBC EH&S staff. The MSDS will be consulted for proper disposal of contaminated items. E. Response Evaluation & Follow -Up An Emergency Response Review Committee has been established for the management and review of BBC's emergency responses. After a HAZWOPER response has occurred, the Emergency Response Review committee will submit a report to management discussing the emergency response. A copy of this report will be kept in the files. The Emergency Response Review Committee: • Operations/Area Manager • Environmental, Health & Safety Manager • Superintendent/Area Foreman The report will identify: • Nature and Cause of emergency • Statistics pertaining to emergency (i.e. damage, injuries, etc.) • Effectiveness of Company Emergency Response Personnel • Corrective Measures taken to prevent recurrence of similar emergency at this location (considering applicability to other locations) DWELLINGS, OFFICES, ETC.

September 4, 2007 Garfield County Building and Planning 108 8" Street, Suite 410 Glenwood Springs, Colorado 81601 Attn: Craig Richardson Re: Bailey Compressor Station Traffic Assessment and Trip Generation Letter, Garfield County, Colorado Dear Mr. Richardson: Per Garfield County requirements, this letter presents the results of a trip generation assessment for the proposed Bailey Compressor Station. This letter also includes a discussion of how vehicles will access the proposed site. The Bailey Compressor Station is to be located along Alta Mesa Road approximately 3 miles south of the Town of Silt in Garfield County, Colorado. The total site area is approximately 10 acres. Access to the proposed compressor station will be from Alta Mesa Road. Site -generated traffic estimates are determined through a process known as trip generation. For this study, Kimley-Horn used information provided by the client to determine the number of vehicles anticipated to access the site per day as well as the number of vehicles anticipated to enter and exit the site during the AM and PM peak hours. These trip generation estimates include the number and types of vehicles that are anticipated to access the site during the construction phase, during normal operations, and in the future. During the estimated sixteen (16) week construction period it is anticipated that the total number of vehicles that will access the facility during a typical day would be approximately twenty (20) vehicles. A vehicle entering the site and exiting the site counts as two trips; therefore, a total of 40 vehicle trips in and out of the site are anticipated during the construction phase of the compressor station. These vehicles would include cranes, boom trucks, semi tractor trailers, concrete trucks, 1 -ton roust- a-bout/welder trucks, and 1/2 and 3/4 -ton company trucks. Once construction is completed and normal daily operation begins, it is expected that approximately eight (8) vehicles would access the site daily resulting in a total of 16 vehicle trips in and out of the site. Typical daily operation vehicles would include 1 - ton and 3/4 -ton technician, pumper, and contractor trucks, %z -ton manager and visitor trucks, and water and condensate removal semis.

All fabricated materials will be stored at contractor's yard and delivered to the job site. Pipe will be strong along the right-of-way during construction of the pipeline. Equipment used during the construction of the pipeline and compressor will be required to stay on R.O.W. at all times with no exceptions. During the construction of the Bailey Compressor Station all materials and supplies to include equipment, will be stored onsite at all times and within the property boundaries. Hydrostatic Testing For the proposed 20 inch and 8 inch pipelines Bill Barrett Corporation (BBC)is not planning to hydrostatically test these two lines. These lines will be ran at low pressures using allowing BBC to test their lines with wellhead pressures. BBC does intend to hydro test their proposed 6 inch steel High Pressure natural gas pipeline. It is estimated that the maximum test pressure of this line will be 1573 psig which is adequate to meet the standards set by DOT and API Specification to test pipelines at 1'/Z times the maximum operating pressure. BBC intends to utilize water from contractors with approved water rights to complete the test. Water will be disposed of at one of their existing water storage sites once test has completed and is successful or trucked of to an approved disposal facility. The hydro test will consist of a 8 hour test. This test will be broken down into three segments during the 8 hour period. The segments are as follows: 2 hour Leak test, 2 hour strength test, 4 hour Stability test. The test shall be recorded with the use of dead weights and a meter chart showing pressure and ambient temperatures. During the first 2 hours of the test readings should be taken in 15 minute increments and then every 30 minutes for the remainder of the test. Pressure shall only be allowed to drop to the estimated minimum pressure. If pressure drops below minimum pressure test will be considered as a failure. Test is to be performed by qualified technicians with approved supervision by a BBC representative or third party inspection company hired by BBC. All equipment used for testing must be calibrated and have current qualification documentation prior to commencement of the test.

DESIGN GUIDE This design guide covers the design, installation and maintenance guidelines for carbon steel pipelines used in natural gas service. 2. CODES AND STANDARDS As a minimum, carbon steel pipelines shall be designed to the latest approved editions and sections of the applicable codes and standards as follows: 3. DESIGN OF CARBON STEEL PIPE 3.1 Allowable Working Pressure 3.1.1 The following formula is from 49 CFR Part 192, Section 192.105, "pipeline Safety Regulations" by the Office of Pipeline Safety, Department of Transportation (DOT). P= 2ST xFxExT D Where: P= Internal design Pressure, pounds per square inch gauge (psig) S= Yield Strength, psi of pipe material in accordance with paragraph 192.107 t= Wall Thickness in inches F= Design Factor determined in accordance with paragraph 192.11 of DOT pipeline safety E= Longitudinal joint factor determined in accordance with paragraph 192.113 of DOT Pipeline Safety Regulations (E=1.0) T= Temperature derating factor determined in accordance with paragraph 192.115 of DOT Pipeline Safety Regulations (T=1.00 for a temperature of 250° or less) 3.1.2 The above equation was based on the allowable working pressures for gas transmission and distribution piping at -20°F to 250°F service temperature. 3.1.3 Corrosion allowance must be added to the calculated wall thickness.

No.: 0 Number: DG -4850 Date: Page: 2 of 10 3.2 Pipeline Sizing 3.2.1 Sizing Equations The AGA flow equation modified by the Colebrook -White transmission factor as shown below is recommended for the most accurate prediction of pipeline flow characteristics. Q= 38.774 10-6 Tb Pb [Pi2—p22j0.5 d25F [G Tr Zavg L] where: Q= Flow rate (MMSCFD Tut= Base Temperature (520°R) Pb= Base Pressure (14.73 psia) Pi= Upstream Pressure (psia) P2= Downstream pressure (psia) G= Gas specific Gravity (air=1.0) T1= Flowing gas Temperature (°R) Zavg Gas compressibility factor L= Pipe Length (miles) d = Pipe Inside Diameter (inches) F = Transmission Factor =4 Logi° (3.71 d/Ke) Ke = Effective Roughness (inches) 3.2.2 Mainline Sizing Criteria Mainlines are sized based on a 5 to 10 psi/mile pressure drop. Physical and economic considerations such as horsepower, pipe availability, fuel gas costs and future expansion may dictate different sizing criteria. Summer or winter gas flowing temperatures and ambient temperatures will be used depending on the basic purpose of the mainline, i.e., winter peak day requirements verses year-round transportation for others, etc. 3.2.3 Branchline Sizing Criteria Branchlines are sized to flow peak hour loads. A specific psi/mile pressure drop criterion is not used. The difference between the available pressure at the mainline tap and the required meter facility inlet pressure will be used, resulting in pressure drop rates up to 20 psi/mile. Pipe sized down to 2" nominal pipe size may be used. 3.2.4 Gathering Line Sizing Criteria Gathering lines are designed for a 5 to 10 psi/mile pressure drop, with a minimum nominal pipe size of 4". Physical and economic considerations such as horsepower and pipe availability, fuel gas costs and future expansion may dictate different sizing criteria.

ROUTE SELECTION 4.1 The route should be the most direct line between accessible starting and terminal points of the pipeline. Exceptions to this may be made for items such as rivers, work areas, rough terrain, archaeological and environmental considerations, towns or populated areas, land use, power lines, roads, railroads and related facilities. 4.1.1 Rivers and ravines should be crossed at right angles and in a straight run of the river. 4.1.2 Rough terrain, wet land and fault zone crossings should be minimized. 4.1.3 Road and railroad crossings should be minimized. 4.1.4 Areas with a high potential for encroachment should be avoided 4.1.5 Areas with high potential for requiring condemnation to obtain right -or -way should be avoided. 4.1.6 The alternative of routing the pipeline in and along a public road or railroad right -or -way should be evaluated. 4.1.7 Pipelines should not be routed parallel and adjacent to power lines where reasonable alternatives are available. 4.2 The start and termination of the pipeline and preliminary route may be determined by using USGS maps. Route information accuracy requires field reconnaissance and/or the use of aerial photography. 4.3 After preliminary determination of the route, an ownership search and preliminary survey should be made to determine actual conditions along the route. Based on the survey and related information, the route should be finalized and resurveyed as required. Property plats, permits and the construction drawings may then be prepared. 5. RIGHT-OF-WAY (ROW) 5.1 Permanent ROW widths should be a strip of land 50 feet in width for a single pipeline. In addition to the permanent ROW, temporary additional work space may be necessary for larger line sizes, at road crossings, river crossings, and areas with side slopes. 5.2 Any conditions or restrictions contained in the easement must be incorporated in the design and construction of the line. 5.3 The granting of a sales meter (faun tap) as a condition of the easement is discouraged. 6. PERMITS 6.1 Environmental permits may be required for a variety of reasons. The Environmental Department shall be consulted relative to any permit requirements. 6.2 Use permits are normally required when the pipeline crosses federal land, state land, state and county highways, railroads and waterways. The design and installation of the pipeline must be in compliance WAGON WHEEL CONSULTING ENGINEERING STANDARDS with the specific permit requirements. Any conditions or special requirements should be indicated on the design drawings and in the contact documents. 7. HANDLING AND STORAGE The interior of all pipe and fittings shall be kept free of dirt, liquids and foreign matter at all times. 8. PIPELINE DESIGN 8.1 Construction drawings and contract documents for pipelines subject to the requirements of 49 CFR Part 192 should be thoughtly reviewed to assure that the design meets the latest requirements of that code. 8.2 The design of any facility considered exempt from Part 192 should be compared to the minimum requirements of Part 192. A tabulation of any deviations should be prepared and included in the permanent documentation of that facility. 8.3 All facilities shall be designed using the applicable design factor to meet the Class Locations as defined in Part 192 8.4 Pipeline cover greater than the minimum specified by Part 192, §192.327 may be required due to easements, permits, road and railroad crossings, drain tile and to provide clearance between the new line and existing pipelines. Also cover greater than minimum requirements may be prudent in agricultural areas due to deep cultivation or operating activities or in areas subject to significant wind or water erosion 8.5 Trenching 8.5.1 In rocky soil conditions, the trench bottom should be undercut a minimum of 4 inches and the unde4rcut filled with fine gravel or clean soil that will provide a good bearing surface for the pipe. 8.5.2 The trench bottom should be flat to eliminate peak loads on the pipe and deter the pocketing of liquids. 8.6 Crossings 8.6.1 Road and Railroad Road and railroad crossing design requirements are often dictated by the permit requirements of the governing body having jurisdictional authority. A permit must be obtained prior to making any crossing. Uncased crossings are preferred and should be pursued in the permitting process. Also, 49 CFR Pert 192, requires a lower design factor for uncased road and railroad crossing in Class I and Class II locations. If unusual loads are anticipated, a stress analysis shall be required.

WAGON WHEEL CONSULTING ENGINEERING STANDARDS CARBON STEEL PIPELINES Rev. No.: 0 Number: DG -4850 Date: Page: 5 of 10 8.6.2 Waterway Crossings Waterways may range from small drainage canals to large navigable rivers and lakes, may of which require a crossing permit from a jurisdictional authority. Wetlands and navigable waterways are normally under the jurisdiction of the U.S. Army Corps of Engineers. Small stream crossings controlled by local authorities may not require special permits and may be accomplished with standard cross-country construction methods. However, the specific requirement should be checked with local authorities before proceeding with the crossing design. The selection of the most suitable location to cross a waterway involves many considerations, particularly if it is of significant size. In selecting and designing the crossing, documentation of the history, geology and hydrology of the waterway and projection of possible future considerations such as bottom scouring and movement of the channel should be competed. Waterway conditions at the time of construction will also influence the selection of the crossing. An accurate survey of the river should be made, noting caving banks, sand bars, and related items in order to arrive at the best location and determine depth below the bottom of the channel. Economic and engineering evaluations will need to be completed to determine the design of the crossing and method of construction to use. For major pipeline systems, consideration should be given to a dual crossing which would provide a backup should failure or damage occur to one of the crossings. 8.7 Foreign Pipeline Crossings The specific requirements for foreign pipeline crossings are normally set by the owner or operator of the foreign line. The minimum cover requirements are maintained and the crossing is approved by the operator of the foreign line. Cathodic test leads should be installed on the company line and the foreign pipeline with the approval of the owner or operator of the foreign line. 8.8 Pipeline Pulling 8.8.1 The effect of pulling a number ofjoined lengths of pipe across the ground by gripping one end results in the generation of a tensile load in the pipe. The maximum force that can be applied to the pipe length in pulling it into position should be calculated prior to pulling. 8.8.2 A pulling head should be used to attach to the leading end of the pipe. This can take the form of a simple rubber pad with a steel cable wrapped around the pipe, or can be more sophisticated in the form of a pulling head. 8.8.3 Under no circumstances should the pipe be pulled by attaching to the flange. If flange assemblies are installed, they musty be elevated to keep from dragging, both in front and behind. WAGON WHEEL CONSULTING ENGINEERING STANDARDS CARBON STEEL PIPELINES Rev. No.: 0 Number: DG -4850 Date: Page: 6 of 10 8.9 Pipe Laying Connections made to valves, unsupported equipment, manholes, etc., shall be supported. A concrete pad shall be installed under the heavy member to resist settlement and preclude the pipe from supporting the component. 8.10 Backfilling 8.10.1 The final backfill material can be the original excavated material or other convenient soil provided it does not contain large rocks, debris or frozen lumps. The backfill should be compacted to 90%. 8.10.2 In areas where a high water table exists it will be necessary to allow for the effect of buoyancy of the pipe and of the backfill material. The conventional trench configuration and the frictional forces and load on the fill will no longer be sufficient to overcome a tendency for the pipe to float. This situation requires that the depth of cover be calculated from the following equation; H _ 0.785 (D2Ww) — Ws D (Ws — Ww) Where: H= Minimum cover in feet D= Diameter of the pipe in feet Wp= Weight of empty pipe in lbs Ws= Saturated soil density in lbs/cubic foot Ww= Density of water in lbs/cubic foot 8.11 Plowing In The plowing in of gas piping will not be allowed without prior written approval of the Client. 8.12 Valve Spacing and Design 8.12.1 Sectionalizing block valves and blow down valves for new transmission and non -rural gathering lines must meet the requirements of 49 CFR, §192.179. 8.12.2 The installation of block valves in rural gathering pipelines and in all pipeline segments that are replaced, relocated or changed shall be based on operating considerations. Hydrotesting is not considered to be replacement, relocation or change and does not dictate that a valve be installed. 8.12.3 Block valves should be located at readily accessible locations, such as near roads, but away from overhead power lines if blow -offs are included.

No.: 0 Number: DG -4850 Date: Page: 7 of 10 8.13 Liquid Removal 8.13.1 Liquid may accumulate at any low point in a pipeline and some means of removal should be considered during the design phase of a pipeline system. Methods typically used for liquid removal in pipelines are siphons, drops and pigging. The selection of the method or combination of methods should be based on the expected liquid volumes and liquid disposal problems. 8.13.2 Siphons are typically installed at low points in the pipeline where liquids can accumulate and in drips and scrubbers. They consist of a pipe inserted through the top of the pipeline using a saddle connection (or piping system) that extends to the bottom of the pipe with a valve to allow blow down of the liquids from the low point. Temporary insertion type siphons are also available. Siphons should not be installed where they may become a restriction to pigging operations. 8.13.3 Drips are fabricated assemblies installed with the pipeline to separate and store liquids. They are generally located at wellheads, in-line on pipelines, at pig receivers and at inlets to plants. The liquid capacity of the drip should be based on the expected volumes of liquids to be removed, time period between draining of the drips and related operating conditions. 8.13.4 Pigging a. Consideration shall be given to the installation of on -stream pigging systems when accumulations of liquids, dirt, wax and related materials would severely decrease the pipeline efficiency or contribute to internal corrosion. Pigs may be any of a large variety of types. b. Pigging will normally require the installation of permanent on -stream launchers and receivers for those facilities that require frequent pigging runs, or those mainline transmission pipelines which cannot be taken out of service. Temporary or mobile type pigging systems may be considered for gathering and those pipeline which can be taken out of service and are pigged infrequently. c. The design for system to be pigged should ensure that no restrictions are included in the system. Where a line size change occurs, the normal practice is to install a receiver and a launcher, although multiple size pigging sections should be considered. Installation of guide bars on all large side connections and liquid removal facilities must incorporate into the design to prevent entrapment or damage to the pig. d. Liquid receiving facilities must be provided and sized to contain the slugs of liquid expected to be removed from the piping by each pig run. 8.14 Branch Connections 8.14.1 Branch connections or side taps should be designed into the pipeline as necessary to combine or split flows, and to provide service to other systems or sale facilities. 8.14.2 Farm taps, although discouraged, may be required by ROW easement. WAGON WHEEL CONSULTING ENGINEERING STANDARDS CARBON STEEL PIPELINES Rev.No.: 0 Number: DG -4850 Date: Page: 8 of 10 8.15 Pipe, Valves and Fittings 8.15.1 The pipe used in the design should be seamless, submerged -arc welded (SAW) or electric resistance weld (ERW). Pipe should be specified to ASTM A106 Grade B or API 5L. The ratio of pipe diameter to wall thickness (D/t) should not exceed 90 without a specific evaluation to be included in the permanent facility records. For welded pipelines, field weldability due to wall thickness should not be of concern for wall thickness 0.156" and above. Added wall thickness for corrosion allowance shall be added when corrosive gas (with high levels of H2S or CO2 with free water) exists in the system. Special chemistry should also be considered for pipe to be used in corrosive gas service. 8.15.2 Valves in pipeline systems shall be rated by an ANSI class designation. Valves 2" and larger must meet API 6D or an approved equal. The pressure rating of the valve must meet or exceed the design pressure of the pipeline. For corrosive gas applications, NACE trim should be specified. Valve ends for connections to pipelines should be either weld -by -weld or weld - by -flange with the weld always on the side serving the most critical service. Some common applications of various valves are as follows: a. Plug Valves Block, isolation and blowdown b. Ball Valves (full open) Hot tap valves, where pressure drop must be minimized or where pigging is a consideration c. Gate Valves Block, isolation and hot tap valves d. Check Valves Direction flow devices at side valves settings and in compressor piping e. Relief Valves Overpressure protection f. Control Valves To control volume or pressure 8.15.3 Flanged connections should be avoided below grade in order to reduce the potential for undetected leaks. Screwed connections 1-1/2" and smaller may be used; however, screwed connections made directly on the pipeline are prohibited except for locations that may be conveniently isolated and there is little risk of mechanical damage from outside forces. 8.15.4 The materials and rating of flanges and fittings for the pipeline must be compatible with or exceed those of the pipeline. 8.16 Pipe Coating and Painting 8.16.1 Sttel pipe installed below ground or submerged must be insulated from the earth to reduce the cost of external corrosion control (cathodic protection current). Pipelines may be protected using a variety of external coatings applied in a coating yard, at the job site or over -the -ditch. 8.16.2 All above ground piping must be painted to prevent atmospheric corrosion. WAGON WHEEL CONSULTING ENGINEERING STANDARDS CARBON STEEL PIPELINES Rev. No.: 0 Number: DG -4850 Date: Page: 9 of 10 8.17 Cathodic Protection 8.17.1 Steel pipelines installed below ground or submerged must be protected from external corrosion using cathodic protection as part of the protective system. 8.17.2 Cathodic protection systems require that pipelines be electrically insulated from other systems at certain points. Insulating flanges or unions should be installed in above ground piping at all plants, meter stations and connections with foreign pipelines. 8.17.3 Cathodic protection is normally provided by a rectifier and ground bed system or sacrificial anodes. The rectifiers are installed as necessary to provide the required protection. Test connections are provided at intervals along the pipeline, generally at road crossings and cased road/railroad crossings. The test connections are typically installed with the pipline by the contractor. The cathodic survey is made by either the Client's cathodic specialist or specialized contractor. Special grounding system should be considered when the pipeline parallels a power line. 8.18 Testing 8.18.1 Radiography is a means to control welding quality during construction 8.18.2 Pressure testing must be conducted on all pipeline systems to establish integrity. Most testing is done with water, however, some testing may be either air, nitrogen or natural gas. Environmental permit requirements must be considered when planning the hydrostatic test. 8.18.3 After completion of a hydrostatic test, the pipeline must be dried. Generally dewatering of the line with cup pigs is all that is necessary. Winter start-up, proximity to the market, or contract requirements may require additional drying. Methanol slugs may be pushed thought the pipline with pigs to remove moisture and suppress the dew point. Methanol may be injected during the start-up to reduce moisture and hydrate problems. Compressed and dried air may also be used with pigs to dry and clean the line. 8.18.4 Under no circumstances shall the total time under test exceed eight (8) hour at 1.5 times the design pressure. 8.18.5 When draining the water from the pipe, beware of creating a vacuum condition. Both ends of the line should be open to atmosphere to allow the water to run freely out of the pipe. 8.18.6 Unless otherwise directed in writing, all tests shall be conducted or withnessed by a Client representative. 8.19 Qualified Welders 8.19.1 Only "Qualiffied Welders" (anyone who has passed a KNE administered welding test within the preceeding 12 months) will be allowed to perform welding on pipe and fittings. 8.19.2 Candidates for qualification or requalification shall fabricate test assemblies for each type and size of material required for a specific job. WAGON WHEEL CONSULTING ENGINEERING STANDARDS CARBON STEEL PIPELINES Rev. No.: 0 Number: DG -4850 Date: Page: 10 of 10 8.20 Line Markers Typical signs include "Caution" or mile post signs and aerial patrol signs. The "Caution" signs should be installed all crossings and other locations where necessary and practical to identify the location of the pipeline to reduce the possibility of damage or interference. If a line is to be patrolled by airplane on a regular basis, aerial patrol signs should also be installed. The fence posts on either side of the pipeline at all crossings shall be painted distinctively. 9.

BiII Barrett Corporation STORM WATER MANAGEMENT PLAN BILL BARRETT CORPORATION MAMM CREEK FIELD GARFIELD COUNTY, CO 0.0 INTRODUCTION This Storm Water Management Plan (SWMP) has been prepared for the BILL BARRETT CORPORATION (the Company) MAMM CREEK FIELD in order to identify Best Management Practices (BMPs) which will be implemented to meet the terms and conditions of the Colorado General Permit for Storm Water Discharges Associated with Construction Activity. The SWMP has been prepared in accordance with good engineering, hydrologic, and pollution control practices, and is designed to constitute compliance with rules and regulations promulgated by the Colorado Department of Public Health and Environment (CDPHE). This SWMP is divided into two sections: the Reference Section and the Site Specific Section. The Reference Section, also referred to as the Master SWMP, contains information that is applicable to all Sites. The Site Specific Section includes Site maps and discussion regarding each Site; this information will be updated over time as the activities at each site progress and change. Both Sections together are referred to as a "Field SWMP." The SWMP Administrator is Scot Donato. The following Sections 1.0, 2.0, and 3.0 comprise the Reference Section of the SWMP. I.0 FIELD PROJECT DESCRIPTION The below sections (a) through (h) follow the General Permit C.1.(a) through (h). (a) THE COMPANY is constructing the oil & gas production facilities Iocated in Garfield County, Colorado, which involves oil & natural gas well drilling, completion and production facilities, and associated roads and pipelines. The facilities meet the CPDHE term of a "common plan of development," which is defined as a site where multiple separate and distinct construction activities may be taking place at different times on different schedules, but still under a single plan. (b) This section discusses the major steps for completion of the different types of construction activities. Construction of each type of facility follows a typical, consistent procedure. The construction sequence for major activities for construction at oil & natural gas well pads consists of: • Clearing vegetation and establishing perimeter stormwater control as shown on the Site diagrams; • Removing and stockpiling topsoil, grading and compacting the project areas level; • Excavating the reserve pit; • Moving in drilling equipment and drilling oil & gas well; • Removing all drilling equipment and moving in completion equipment to complete well; • Removing all completion equipment and installing semi-permanent production equipment; and • Re-seeding/reclaiming the remaining disturbed area with uniform vegetative cover to at least 70% of pre - disturbance levels, referred to as Final Stabilization. Note that stabilized unpaved surfaces can meet the definition of Final Stabilization for those areas that must remain unvegetated for production operations at a well pad. • Portions of a site returned to cropland use and the control of the farmer to not require establishment of vegetative cover. Once returned, these areas are no longer regulated as construction activity. The sequence of major activities for construction of the access roads consists of: • Clearing and grading the road right-of-way; • Cutting the roadside drainage ditches; • Contouring and compaction of existing or imported materials; • Emplacing and compacting roadbase as appropriate; • Re-seeding/reclaiming the remaining disturbed area with uniform vegetative cover to at least 70% of pre - disturbance levels. • Following construction of the well for which the access road was built, dirt road surfaces will remain for access to the well and are considered `stabilized unpaved surfaces.' The sequence of major activities for construction of the pipeline route consists of: • Clearing and grading the road right-of-way; • Trenching for the pipeline install; • Welding pipe together and placing in the trench; • Backfilling and compacting the trench; • Re-seeding/reclaiming the remaining disturbed area with uniform vegetative cover to at least 70% of pre - disturbance levels. The sequence of major activities for construction of the completion and production facilities consists of: • Installing production facilities including tanks, separators, and piping. • Regrading the surrounding area for reclaimation as appropriate. • Re-seeding/reclaiming the remaining disturbed area with uniform vegetative cover to at least 70% of pre - disturbance levels. Where the above procedures differ during actual construction activities and the change results in a change to a BMP at a site, this will be described in the corresponding Site -Specific Section. (c) The approximate total area of the Mamm Creek Field is 20,306 acres. The approximate areas to be disturbed at each individual Site are as described in the Site -Specific Section. (d) USGS topographic maps were used to evaluate the topography of the Sites. The topography and natural site drainage are discussed in the Site Specific Sections. If wetlands are present at any individual facility and the potential impact to the wetlands is determined to fall under the jurisdiction of the U.S. Army Corp. of Engineers (Army Corps), the Army Corps will be consulted for the proper permit(s) as appropriate, and the construction methodology outlined in the permit will be followed. (e) The majority of the project area is located in short grass prairie or range land, and existing vegetation may include range -type grasses, sage brush, forbs, pinyon, juniper trees, willows and cottonwoods. Vegetative ground cover ranges from approximately 10% to 70%. A description of the existing vegetation at each of the Sites is included in the Site Specific Sections. (0 The most common substances that have the potential to be spilled within the project area are: I) fuel and lubricants for construction equipment and vehicles; 2) water or gel based frac fluids (surfactant, friction reducer, acid, potassium chloride) using during completion, sand; 3) produced water; and 4) produced crude oil/condensate. The locations for storage and handling of these substances will be chosen based on protection from moving vehicles, distance from surface water bodies, distance from sloped ground, and other practical factors. The locations are shown on the Site maps in the Site -Specific Section. (g) No non -storm water components of storm water discharge such as irrigation return flows or spring discharge are anticipated. If non -storm water discharges are found to be required at a Site, a discussion will be included in the Site - Specific Section. (h) The potential receiving water bodies for surface water drainage from the Sites will be Divide Creek, Dry Hollow Creek and Mamm Creek. The receiving water body for each Site is noted in the Site -Specific Section. 2.0 STORMWATER POLLUTION PREVENTION This section covers the specifications of the Best Management Practices (BMPs) that will be applied during construction activities covered in this SWMP. The implementation of BMPs in the field will be shown on the Site maps, and deviations from the specifications below will be discussed in the Site -Specific Section. 2.1 Erosion and Sediment Controls (BMPs) Erosion control will be accomplished through a combination of construction techniques, use of structural features, and non-structural practices. Erosion controls, as appropriate, will be implemented prior to successive phases of each project including; site clearing, road grading, and final pad grading. The controls will remain in place and active until the project site is appropriately stabilized. 2.1.1 Construction Techniques Excavation a. Excavated materials will be stored next to the excavation to protect the material from vehicular and equipment traffic. As required by the Reclamation Regulations all excavation operations on cropland shall separate and store the various A, B, and C soil horizons. b. Excavation in especially sensitive areas may be conducted according to special techniques as specified by the landowner/agency representative c. Materials excavated will be utilized as backfill when practicable. An exception may be some rock excavated by blasting. In these areas, some select backfill may be required to protect the project area. Excess rock may be pushed into rock filter dikes, used in energy dissipation zones below culverts, constructed into rock check dams within grassed swales, distributed over a portion of the project area or disposed of' off-site. d. All cuts made in steep rolling terrain during construction will be regraded and contoured to blend into the adjoining landscape and to reestablish the natural drainage patterns. e. Materials that are unsuitable for use as backfill or excess backfill material will be disposed at approved locations. f. Temporary workspace areas will be restored to approximate pre -construction conditions. Streams and Wetlands a. During construction near perennial streams, lakes or wetlands, sedimentation (detention) basins, straw bales, or fabric filters may be constructed to prevent suspended sediments from reaching downgradient watercourses, streams, lakes or wetlands. b. Disturbance of riparian and wetland areas will be kept to the minimum needed for construction and installation. Approaches to streams will involve selective clearing of vegetation. Willows and cottonwoods cleared during construction will be reestablished as part of reclamation. c. If work occurs in willow/shrub type areas, the small trees and shrubs may be trimmed to ground level in areas where equipment will be working. d. The first 1.0 feet of topsoil from wet areas will be salvaged and redistributed over the excavation as quickly as reasonably possible following installation of the pipeline. The seeds, roots, rhizomes, tubers, and bulbs present in the topsoil will enhance and help speed up reclamation of wet areas disturbed by construction. e. Where appropriate, water bars or sediment filters, such as staked straw bales or silt fences, will be constructed adjacent to the crossings to reduce potential sedimentation in streams or wetlands. Trenching will cross dry streams. Small flowing streams will be crossed by fluming or trenching with a downstream silt barrier to reduce downstream sedimentation. 2.1.2 Structural Features Structural site management practices refer to physical structures such as vegetative filters, soil roughening, crimped straw, brush dams, rock filter dikes, silt fences, straw bale dikes, water bars, or equivalent sediment controls installed so as to protect down slope surface waters, wetlands and roads from sediment flow due to runoff from a storm event. Specifically, during construction, soil roughening, crimped straw, silt fences, straw bale dikes, water bars, terracing, or equivalent sediment controls are recommended for all side slope and down slope boundaries for the construction area. Alternatively, a detention basin providing storage for runoff from a l0 -year, 24-hour storm event could be implemented. Below are listed several considerations for structural practices: a. To minimize disturbance associated with installation of the Facility, level and gently sloping terrain outside the project area will not be graded, except where reasonable for construction equipment stability and fire safety. b. Silt barriers and deterrents (eg. crimped straw, brush dams, rock filter dikes, silt fences, hay bales, or water bars) will be installed as needed on down -gradient portions of the project area. Typical silt barrier construction are shown on BMP figures c. Side hill cuts will be kept to a minimum to protect local resources while providing a safe and stable plane for the efficient and safe use of equipment. d. Where conditions warrant, erosion control structures such as berms, water bars, diversion or collection channels, terraces, or culverts will be constructed to divert water away from the project area and to reduce soil erosion along and adjoining areas disturbed during construction. e. In areas of' steep slopes that are not annually cultivated, water bars or runoff diversions, will be installed as indicated in Table 1. The water bars will begin and end in undisturbed ground at a 2% slope. f. Culverts may be installed at a grade ranging from 2-5 %. Inlet protection may include inlet aprons and rock armoring around the culvert perimeter while below grade inlet sumps may be installed to enhance deposition. Outfall protection may include the use of a rock armored splash pad to slow water. Table 1 - Spacing for Erosion Control Structures Slope Diversion Spacing (Feet) 5-15% 300 16-30% 200 30+ % 100 Table 2 - (BLM Cold book) Slope Diversion Spacing (feet) 2 % 300 2-4% 200 4-5% 75 5+ % 50 Post -Construction Structural Measures will include: a. Permanent water bars will be installed on steep slopes according to Table 1 and at wetland and stream crossings. b. Trench plugs will be installed on steep slopes according to Table I and at wetland and stream crossings. After restoration work is complete, required repairs to vegetation and erosion and sediment control structures will be completed along with routine scheduled pipeline inspections and/or in response to other notification. 2.1.3 Non -Structural Practices Non-structural practices such as leaving existing vegetation, shrubs, and trees in place where possible, and interim reclamation such as interim seeding of select areas, mulching, geotextile fabrics, and vegetative buffers, will be employed wherever practicable to assist in preventing erosion from project sites. The following describes some general practices, and implementation at each site will be discussed in the Site- specific information. a. Existing cover will be removed only where necessary for the operation of equipment. In general, vegetation will be cut off near ground level leaving the root system intact. Cuttings may be stacked into a brush dam, distributed along the contour across reclaimed areas during reclamation or disposed of as directed by the landowner/agency representative. b. Trees and large shrubs that are not cleared from the site will be protected from damage during construction by avoiding them with equipment. For example, bulldozers will maintain their blades in a raised position except for areas designated for clearing or to smooth out sharp breaks in relief. c. Grading outside the project area will be done only when necessary for the safe operation of equipment and for fire protection. d. Trees will be cut or trimmed only to facilitate clearing, grading, and safe installation. Trees which must be removed will be cut. Trees outside the area of disturbance will not be cut, but will only have overhanging limbs removed by cutting, with the tree to remain. The bulldozers will maintain their blade in a raised position in sensitive visual resource areas, where practicable. e. Interim reclamation of soil stockpiles and other appropriate areas may be implemented to prevent erosion from these areas. Interim seeding, mulching, or geotextile fabrics may be used to stabilize slopes. Cut or existing live vegetation may be used as a vegetative buffer to slow runoff water flow and prevent sediment from reaching live water. Following construction, the following non-structural practices will be employed: f. Unless otherwise directed by the landowner or the jurisdictional authority, rocks, cut vegetation, and other surface material temporarily stockpiled for construction will be redistributed back across non -fenced portions of the project area. g• Disturbed areas will be seeded using seed mixes appropriate to the location. Local soil conservation authorities with the U.S. Natural Resources Conservation Service, surface owners and/or reclamation contractors familiar with the area may be consulted regarding the correct seed mix to be utilized. h. On terrain where drill seeding is appropriate, seed may be planted using a drill equipped with a depth regulator to ensure proper depth of planting. The seed mix will be evenly and uniformly planted over the disturbed area. Drilling may be used where topography and soil conditions allow operation of equipment to meet the seeding requirements of the species being planted. i. Broadcast seeding will occur on steep terrain and on areas such as where the cut vegetation and rocks were redistributed over the right-of-way. j. Seeding will be done when seasonal or weather conditions are most favorable according to schedules identified by the jurisdictional authority, reclamation contractor, or landowner. Whenever possible, seeding will be timed to take advantage of moisture, such as early spring or late fall to benefit from precipitation. k. Seed mixes will be planted in the amount specified in pounds of pure live seed/acre, where necessary. There will be no primary or secondary noxious weeds in the seed mix. I. As far as possible, the reestablishment of vegetative cover as well as watershed stabilization measures will be scheduled during the working season and before the succeeding winter. In any case, revegetation treatments will be accomplished as soon as practical following completion of facility construction. m. In general, the applicable portions of the project area will not be mulched during reclamation and revegetation. Mulch will only be applied at the request of the jurisdictional authority in areas where the cut vegetation and rocks are not redistributed over the disturbed area. (The cut vegetation and rocks will act like mulch in the areas where they are applied.) Where straw or hay mulch is requested, the mulch will be applied and crimped into the soil. n. The need for fertilizers will be determined in conjunction with the jurisdictional authority, surface owners and/or reclamation contractors. If fertilization is necessary, the rates of application will be based on site- specific requirements of the soil. 2.2 Phased BMP Implementation There are many possible options for application of BMPs during the phases of construction outlined in Section 1 (b) above. The actual implementation will depend on the conditions at the individual Sites. As such, site-specific BMP changes from phase to phase will be noted on the Site maps and, if needed, described in writing in the Site -Specific Sections. Each time that a BMP is changed, the Site map will be updated. The Site maps and written sections are intended to be dynamic - changing frequently to reflect the actual conditions in the field. The exception to this will be at the very beginning of the activities, when the Site -Specific Sections will show the anticipated activities. 2.3 Materials Handling and Spill Prevention Hazardous materials and petroleum products to be used in construction of the facilities are limited to diesel fuel and lubricants for construction equipment and vehicles; small quantities of paints and solvents; water or gel based frac fluids (surfactant, friction reducer, acid, potassium chloride) using during completion; produced water; and, crude oillcondensate. Material Safety Data Sheets (MSDSs) for materials to be used on sites will be available either at the Site or the closest regional office. Practices for the prevention of pollution due to materials handlin are specifically outlined in the Spill Prevention, Control and Countermeasures (SPCC) Plan. available at the Silt field office. The general BMPs that will be employed at all sites include: • Refueling and lubrication of vehicles will be conducted a minimum of 100 feet back from flowing streams and wetlands. • Spills will be promptly cleaned up and contaminated materials hauled off-site and disposed of/recycled properly. • Quantities of materials on site will be limited to "as -needed" for the immediate operations underway. • All waste from materials imported to the construction site are to be removed for disposal/recycling to an appropriate licensed disposal/recycling facility, including sanitary sewage facilities (typically portable). 2,4 VEHICLE TRACKING CONTROL To prevent tracking of sediment onto public roads, the facilities shall have, at a minimum, compacted ingress and egress areas adjacent to public roads. Other means such as gravel/scoria placement, or cattle -guards may be utilized if appropriate. 2.5 WASTE MANAGEMENT AND DISPOSAL No wastes of imported materials shall be buried, dumped, or discharged to waters of the State, and there are no anticipated pollutant sources from areas other than construction areas. 2.6 GROUNDWATER AND STORMWATER DEWATERING roundwater from the wells is `produced water' and will be managed by storing in the reserve pit during drilling activities nd in a tank during production activitie4 tipAhekdomring activities are anticipated, as precipitation would bq pected to infiltrate and evaporate; 3.0 MAINTENANCE and INSPECTION Maintenance will be the responsibility of the Company. Maintenance will be performed on an as -needed basis based upon the results of inspections conducted at the site or general observations during any reason for being present on the site. The baseline schedule for inspection of the construction sites is outlined below. If deviations from the baseline schedule are found to be required, approval of alternative schedules will be pursued from the CDPHE. Information regarding an alternative schedule will be included on the respective Site-specific section. 1. An inspection of the Site to document pre-existing conditions will be conducted prior to construction activities. 2. During construction activities, inspections will be conducted at least every 14 calendar days and within 24 - hours of any precipitation event exceeding 1.0 inch during construction and prior to initiating reclamation. i. An exception to the 24-hour post -storm inspection requirement is if a site is "temporarily idle," meaning that no construction activities will occur following a storm event. In this case, an inspection is required prior to re -commencing construction activities, but no later than 72 hours following the storm event. If this exception occurs, it will be documented in the Site-specific section. 3. In the case where the following three conditions are met, the permittee is allowed to reduce the inspection frequency to once a month, and post -storm inspections are not required. The conditions are: i. All construction activities that will result in surface ground disturbance are completed (this may include some well completion activities); ii. All activities required for final stabilization, in accordance with the SWMP, have been completed, with the possible exception of the application of seed that has not occurred due to seasonal conditions or the necessity for additional seed application to augment previous efforts (this allows for seeding to occur in more favorable growing conditions); and iii. The SWMP has been amended to indicate those areas that will be inspected in accordance with this reduced schedule. This will be noted in the Site-specific section of this SWMP. The monthly schedule described above is allowed for sites within a field permit that meet the final stabilization preparation criteria and are waiting for the 70% vegetative cover to be achieved. 4. Inspections are not required at sites where construction activities are temporarily halted, snow cover exists of the entire site for an extended period of time, and melting does not pose a risk of surface erosion. If this situation occurs, it will be documented in the Site-specific section of this SWMP. 5. Inspections will be documented and these records kept on file for three years following reclamation. 6. Negative inspection results will be corrected as soon as practicable. Reporting requirements for noncompliance are outlined in Part II A. 3 of the General Permit. The 24-hour spill reporting hotline is 1-877-518-5608.
