CNAEP is the operator and 100 -percent surface/mineral owner of about 40,000 acres north of De Beque, Colorado. The company also controls an additional 75,000 acres of severed mineral rights in the vicinity. Development of this natural gas field is referred to as the Piceance Basin Natural Gas Development Program (PBNGP). The project will progress through the typical phases of natural gas production with exploration, expansion to a pilot phase (validating the exploration findings), and depending on physical findings and economic conditions, development of the remainder of the field. The project exploration phase was completed during 2006 with the Skinner Ridge Field, 13 -well delineation program. Favorable results from these wells initiated the next phase of the project, which is designated the Early Production System (EPS). The EPS includes operations planned from mid -2007 through 2009 primarily located within the Clear Creek drainage (see Maps - Figure 1). The EPS includes construction of support facilities and implementation of operations associated with the development of four well pads and two service pads. Two state-of-the-art directional drilling rigs will be utilized to install up to 22 wells per pad. The project infrastructure will include access roads, offices, temporary housing, utilities (water, sewage, electricity), storage areas, pipelines (water, gas, condensate, produced water), and processing / treatment equipment. Operations will include road construction, equipment transfer, facilities installation, drilling, well installation and development, material supply, production processing, and general maintenance. If the EPS results are favorable the program will be ramped up to full scale with the use of 6 to 10 drilling rigs over the next 10 to 15 years. CNAEP is implementing their internal Environmental, Social, and Health Impact Assessment (ESHIA) process for the PBNCG Project. While this process has been used around the globe, the PBNCG Project will be the first execution of these procedures in North American. The ESHIA process is designed to integrate project needs and site specific regulations and concerns. It also identifies problem areas and attempts to develop mitigation plans prior to construction or initiation of operations. CNAEP has contracted with Environmental Resource Management (ERM) of Denver, Colorado, to perform the project ESHIA. 1 Nature and Character of Special Use Permit Please submit, in narrative form, the nature and character of the Special Use requested. Submit plans and supporting information (i.e. letters from responsible agencies). Include specifications for the proposed use including, but not limited to, the hours of operation, the number and type of vehicles accessing the site on a daily, weekly and/or monthly basis, and the size and location of any existing and/or proposed structures that will be used in conjunction with the proposed use, and provisions for electric power set vice and any other proposed utility improvements. Be specific. As part of the EPS development CNAEP proposes the installation and operation of a 21,000 - cubic -yard capacity, lined Cuttings Pit. The facility will be located on portions of Tracts 97 and 127 of Section 27, Township 6 South, Range 98 West, 6th Principal Meridian, Garfield County, Colorado (see Maps - Figure 2). The pit will be used to store drilling cuttings when the well -pad cuttings pit capacity is exceeded, Chevron North American Exploration and Production Company Cuttings Pit Special Use Permit Piceance Basin Non -Conventional Gas Project 29021-003 1 Document No: 006-31-14-01 1.1 Location The proposed Cuttings Pit is situated about 0.3 mile west of CR 211 on an existing well pad road, located about 1.3 miles north of the intersection of CR 204 and 211 (see Maps - Figure 2). The EPS project area can be accessed from Interstate 70, exit 62, by traveling north on local Road 45N. Road 45N north of De Beque, Colorado, is also known as Roan Creek Road/Drive and CR 204. The intersection of CR 211 and CR 204 is located about 12.5 miles north northwest of De Beque. The existing pad access road on the north side of CR 211 will be the Man Camp entrance (see Maps - Figure 2). The footprint of the facility is about 3,0 acres. 1.2 Cuttings Pit Purpose The drilling rigs will generate significant quantities of cutting because of the depth and number of wells. A limited amount of storage capacity is provided on the well pad, but additional storage will be required to handle the total volume. A centrifuge may be used at the individual well pads to reduce the cuttings water content, snaking the material easier to handle and transport. The onsite storage area eliminates the need to truck the cuttings to offsite locations. If analytical tests show that the cuttings material to be benign, the pit will be covered, and the area will be reclaimed. Alternatively, if the cuttings contain contaminants (e.g., metals) above regulatory limits, the material will eventually be shipped to the appropriate disposal facility. The general size of the proposed Cuttings Pit cell is 200 ft x 300 ft x 15 ft deep for a capacity of about 21,000 cubic yards (2 ft of freeboard). The facility was sized to service the EPS phase of the project and potentially into the initial full field development. 1.3 Hours of Operation The Cuttings Pit will be used seven days a week on an as needed basis with operations typically limited to daylight hours. 1.4 Vehicles / Traffic / ReguIatory Requirements A preliminary EPS traffic plan was previously provided in the EPS Plan of Development, which details estimates of traffic on area roads and highways. A period of increased vehicle traffic is anticipated until proposed mitigation measures can be implemented. Initial traffic associated with the Cuttings Pit will be the excavation, grading, and site preparation. Once the site preparation is complete, liner deliveries and the associated installation crews will generate short term traffic. Additional deliveries / installations will include a security / wildlife fence and gravel / fill material for the access road and pit entrance. Assuming 10 days per well and about 3,000 cubic yards of excess material requiring movement to the Cuttings Pit, about 14 daily trips would be required (10 -cubic -yard trucks). However, the actual required daily loads may vary depending on the drilling operations. All vehicles working within Garfield County Right of Ways will be licensed and registered in the State of Colorado. Vehicles hauling equipment and materials will abide by Garfield County Road and Bridge Departments oversize / overweight regulations. All vehicles requiring an oversize / overweight permit will send a letter showing proof that they can operate under a known bond holder on file with Garfield and Mesa County Road and Bridge Departments before a permit will be issued. Chevron North American Exploration and Production Company Cuttings Pit Special Use Permit Piceance Basin Non -Conventional Gas Project 29021-003 2 Document No: 006-31-14-01 CNAEP has contracted with Hyland Enterprises, Inc. (see attached Hyland Contract) to supplement the County maintenance operations (scheduled hours 5 am to 5 pm) through the winter months. Hyland also will provide general maintenance services for the site roads. A second contractor, Ken Small Industries, may supplement these services. 1.5 Civil Specifications / Regulatory Requirements The Cuttings Pit area will be graded as specified in Drawings 006-12-11-111-01 rev. B and 006- 12-11-114-01 rev. B (see Drawings). The access road to the Cuttings Pit was previously graded for a well pad but may be modified to handle the truck traffic. Storm -water / erosion controls will be installed in accordance with the best management practices specified by the site Storm Water Management Plan (SWMP) (SWMP and Construction Storm Water Permit are provided as attachments). Drawings 006-12-1 1-061-01 rev. B and 006-12-1 1- 065-001 rev. B (see Erosion Control Drawings) details site specific storm -water controls and will be included as an addendum to the site SWMP. Bi -weekly SWMP inspections will be conducted and documented to ensure site stabilization measures are adequate and / or identify areas that need repair / improvement. Existing topsoil will be stockpiled and stabilized for the eventual site reclamation in accordance with specific SWMP requirements. Seed mixes used for site stabilization and revegetation will be in compliance with Garfield County Reclamation Standards. The stockpile will be monitored and controlled for noxious weeds throughout the operation of the Cuttings Pit. General information concerning the area reclamation plan for the area is provided in Section 8.4. A gated, six-foot chain-link fence will be installed around the pit area to control access and prevent wildlife from becoming trapped in the pit. The facility gate will be locked when no one is present at the site. A site wide construction dewatering permit is currently being obtained from the Colorado Department of Public Health and Environment (CDPHE) as a precaution for the EPS development. Dewatering operations are not expected at this site because of the sandy soil and elevation above the Local water table. 1.6 Structure Specifications / Regulatory Requirements Currently there are no structures planned at the Cuttings Pit area. 1.7 Electrical Utilities / Regulatory Requirements No on-site power will be required for these operations. 1.8 Floodplain No Federal Emergency Management Agency (FEMA) flood map was available for the Clear Creek area. To properly evaluate the area for flooding issues, a preliminary, 100 -year floodplain was developed for Clear Creek in accordance with FEMA guidance and specifications. The result of that analysis is provided as Figure 3 (see Maps). A report summarizing the findings of the Clear Creek floodplain analysis will be published in June, 2007, and be provided to the County. The current analysis indicates the Cuttings Pit is not located in the floodplain. Chevron North American Exploration and Production Company Cuttings Pit Special Use Permit Piceance Basin Non -Conventional Gas Project 29021-003 3 Document No: 006-31-1401 1.9 Noxious Weeds An initial survey of noxious weeds in the Clear Creek drainage was completed during November, 2006, to determine the extent of the problem. The results were presented in the Integrated Vegetation and Noxious Weed Management (IVNWM) Plan for the Chevron Clear Creek 8 -Inch Pipeline (see attached IVNWM, WestWater Engineering, December, 2006). The study indicated that about 50 -percent of the valley floor has been infested with noxious weeds. Supplemental information has been reported in a CIear Creek biological survey completed by WestWater during May of this year (see Section 9.1). The recent survey included the majority of the Clear Creek basin including the surrounding steep talus slopes. Survey results indicated that the entire drainage is affected by noxious weeds (see IVNWM attachment). Information from these studies will be used to identify noxious week infestations and develop management techniques. All identified noxious weeds will be removed during the initial site grading. Maintenance operations will include continuing control of all noxious weeds using a combination of removal and revegetation techniques. 1.10 Safety / Security / Emergency Response Site personnel will be trained to report fires or other emergencies in accordance with the CNAEP Emergency Response Plan (see attached ERP). The ERP is a living document that will incorporate changes to facilities and operations as the various systems come on line. Coordination meetings will be held with the De Beque Fire Chief and other emergency agencies to address site specific issues. A detailed map and GPS coordinates will be provided to the Garfield County Sheriff's Office and De Beque Fire Chief as part of the facility ERP. The map will provide sufficient detail to inform the officials of the site location, the types of facilities, and possible hazards that may be encountered. Upon finalization of the Cuttings Pit design, meetings will be held with the De Beque Fire Chief to determine if additional fire protection is required. Portions of the pit liner will be sufficiently rough to allow the slope to be climbed in case of someone accidentally falling into the pit. The access ramp also will provide an escape route. The area will be fenced to prevent access by unauthorized personnel and wildlife. No outdoor cooking / fires will be permitted at the Cuttings Pit location. A Class ABC fire extinguisher will be provided at the access gate for additional coverage in the event of a vehicle fire. All personnel accessing the site will be trained in the proper operation of extinguishers. All employees and contractors will comply with the provisions of the CNAEP Hazard Elimination / Safety (HES) Plan (see attached HES). Applicable requirements will be detailed in any Master Service Agreement and must be met prior to any contracting activity. Noncompliance with the policy will result in immediate dismissal and termination of the contract. 2 Water Supply / Wastewater Management Systems Chevron North American Exploration and Production Company Cuttings Pit Special Use Permit Piceance Basin Non -Conventional Gas Project 29021-003 4 Document No: 006-31-1401 If you will be using water or will be treating wastewater in conjunction with the proposed use, please detail the amount of water that would be used and the type of wastewater treatment. If you will be utilizing well water, please attach a copy of the appropriate well permit and any other legal water supply information, including a water allotment contract or an approved water augmentation plan to demonstrate that you have legal and adequate water for the proposed use. Cuttings Pit operations will not require any water / wastewater systems. 3 Site Plan / Property Map Submit a site plan /map drawn to scale that portrays the boundaries of the subject property, all existing and proposed structures on the property, and the County or State roadways within one (1) mile of your property. If you are proposing a new or expanded access onto a County or State roadway, submit a driveway or highway access permit. A site plan of the property and proposed facilities and access is provided in Drawing 006-12-1 1- 111-01 rev. B (see attached Drawings). Figures I through 3 (see Maps) shows the existing county roads and general property owners within one -mile of the site. A preliminary plat of the Cuttings Pit is provided in the Plat attachment. 4 Topographic Vicinity Map Submit a vicinity map showing slope 1 topography of your property, for which a U.S.G.S. 1:24,000 scale quadrangle map will suffice. The topographic vicinity map is provided as Figure 2 (see attached Maps). The steep cliffs in many portions of the project area represent a falling rock hazard. These issues have been addressed by the ESHIA process and possible mitigation methods will be incorporated into project planning and the site HES and ERP. 5 Assessor's Map / Adjacent Landowners Submit a copy of the appropriate portion of a Garfield County Assessor's Map showing all the subject property and public and private landowners adjacent to your property (which should be delineated). In addition, submit a list of all property owners, public and private landowners and their addresses adjacent to or within 200 ft. of the site. This information can be obtained from the Assessor's Office. We will also need the names (if applicable) of all mineral right owners of the subject property. (That information can be found in your title policy under Exceptions to Title). A copy of the appropriate portion of the Garfield County Assessor's Map with the marked site location is provided in the Assessor Map attachment. The list of adjacent property owners is provided as the Property Owner attachment. Figure 3 (see Maps) also provides general information about surrounding property owners. 6 Property Deed Submit a copy of the deed and a legal description of the subject property, Chevron North American Exploration and Production Company Cuttings Pit Special Use Permit Piceance Basin Non -Conventional Gas Project 29021-003 5 Document No: 006-31-14-0 I The deed for the entire CNAEP Piceance Basin property is provided in the Deed attachment. Supplemental information concerning the tracts associated with the Cuttings Pit location also are provided. 7 Authorization Letter If you are acting as an agent for the property owner, you must attach an acknowledgement from the property owner that you may act in his/her behalf. A letter authorizing Washington Group International to represent CNAEP in the permitting activities is provided in the Authorization Letter attachment. 8 Water & Wastewater Management / Street Improvements / Project Visual Effects Submit an statement that specifically responds to each of the following criteria from Section 5.03 of the Zoning Regulations: (1) Utilities adequate to provide water and sanitation service based on accepted engineering standards and approved by the Board of County Commissioners shall either be in place or shall be constructed in conjunction with the proposed use. (2) Street improvements adequate to accommodate traffic volume generated by the proposed use and to provide safe,convenient access to the use shall either be in place or shall be constructed in conjunction with the proposed use; (3) Design of the proposed use is organized to minimize impact on and from adjacent uses of land through installation of screen fences or landscape materials on the periphery of the lot and by location of intensively utilized areas, access points, lighting and signs in such a manner as to protect established neighborhood character; 8.1 Water and Sanitation Service The Cuttings Pit operations will not require any water or sanitation services. 8.2 Road Improvements / Issues Surface improvements on CR 211 were completed in late May and early June (addition of 4 - inches of gravel). CNAEP is studying improvements needed to handle the increased traffic on the existing dirt road that continues along Clear Creek. A representative of Garfield County Road and Bridge Department indicated that presently no driveway permit is required at the transition between CR 211 and the existing dirt road, but a stop sign should be provided. If major modifications are made at this location this issue will be revisited. Improvements to CR 204 also are planned but there has been a delay due to the costs associated with the early bids provided to the County. The Colorado River bridge that provides access to De Beque from Interstate 70 (I-70) is scheduled for demolition in August, 2007, in preparation for the bridge replacement. The 45 Road, V.5-45.3 Bridge replacement is expected to take about a year to complete. A detour from the De Beque 1-70 exit (Exit 62) requires heading east on the frontage road to W.5 road and back to 45 Road (Roan Creek). However, there is a height restriction of 15 -ft on this route. Vehicles greater than 15 -ft need to exit 1-70 at Exit 75 (Parachute) and continue west on the frontage road toward De Beque to W.5 road and back to 45 Road (Roan Creek) north of De Beque. A map posted by Mesa County of the affected area is provided (see 45 Road Bridge attachment). Chevron North American Exploration and Production Company Cuttings Pit Special Use Permit Piceance Basin Non -Conventional Gas Project 29021-003 6 Document No: 006-31-14-01 Another transportation issue associated with shipments along the I-70 corridor is the closure of the eastbound lanes at the Hanging Lake Tunnel near Glenwood Springs due to a crack in the tunnel ceiling. All traffic through this section of I-70 will be routed through the westbound lane. Repairs are expected to be completed late in 2007. 8.3 Visual Effects The proposed Cuttings Pit location is in a remote region of Garfield County. Visual effects include the physical presence of the facility and operational traffic. Because of the limited operations additional mitigation measures are not anticipated at this time. 8.4 Reclamation and Revegetation Plan When the Cuttings Pit is no longer needed for operations, the site reclamation will begin. If the material is determined to be benign, the cuttings will be graded to an appropriate contour. The liner edges then will be removed from the berm and used to cover the cuttings surface. One -foot of fill will be placed over the cover, followed by six -inches of topsoil (if available), which will be planted with native vegetation. Reclamation and revegetation activities will be in accordance with requirements outlined in Garfield County Zoning Resolution 5.02.21 (11), General details of the re -vegetation activities are provided in the IVNWM Plan and SWMP and will be included in the final revegetation plan. If the cuttings material exceeds regulatory requirements, the cuttings will be moved to either an on-site or off-site disposal facility. The liner will then be removed, the area will be re-contoured, and reclamation will be completed as discussed in the previous paragraph. Future planning for full-scale development may determine that site has value for alternative purposes. New permits will be obtained and a modified site reclamation plan will be submitted in the event of such change. 9 Use Specific Standards Depending on the type of Special Use Permit requested. you may need to respond to additional review standards in the Garfield County Zoning Resolution Section 5.00 [Supplementary Regulations]. This may include uses such industrial uses [section 5.03.07 & 5.03.081, Accessory Dwelling Units [section 5.03.21], Utility line/Utility Substations, etc. Specific sections of the Zoning Resolution which can be located on the Garfield County web site at http./fwww.garfieldcounty.com/building_and_planning/index.htm, or information can be obtained from this office. Because the Cuttings Pit supports operations associated with the development of natural gas, additional requirements must be met for Garfield County approval. The following details applicable supplemental information not covered in Sections 1 through 8. 9.1 Environmental / Social Studies A Class III Cultural Resources Inventory (Carl E. Conner and Barbara J. Davenport, June 3, 2005) and a Biological Survey (WestWater Engineering, July 11, 2006) were performed as part of the permitting process for an 8 -inch gathering pipeline that will be part of the EPS. These studies provide baseline information for the ESHIA process and have been considered during the design process. Chevron North American Exploration and Production Company Piceance Basin Non -Conventional Gas Project 29021-003 7 Cuttings Pit Special Use Permit Document No: 006-31-14-01 WestWater Engineering recently completed a biological survey of the entire Clear Creek drainage (see attached Clear Creek Biological Survey, WestWater Engineering, May, 2007). The study addressed birds of conservation concern; threatened, endangered and sensitive plant species; noxious weeds; waters of the United States; aquatic habitat; and general wildlife observations. Sensitive habitats have been identified and procedures are being generated to address nearby activities. Copies of the listed reports are provided as attachments for reference purposes. 9.2 Supplemental Industrial Operations Requirements A preliminary impact statement of the EPS, which includes the Cuttings Pit facilities, is provided as the EPS Preliminary Plan of Development that was submitted with this permit. Specific applicable statements are as follows: No water will be removed or discharged from any of the State's waters without applicable permits. Any discharge will meet the drinking water standards controlled by the Colorado Department of Health and Environment. Dust generated by vehicle traffic will be controlled with adequate water trucks and the addition of gravel to CR 211. The Cuttings Pit will not generate vapor, dust, smoke, glare, excessive noise, vibration, or other emanations. Vehicle traffic to and from the Cuttings Pit will have effects on wildlife but the ESHIA process will be used to identify problem areas and determine mitigation options. Mitigation recommendations will be provided to project management, who will evaluate the alternatives and implement appropriate measures. A bond for the site reclamation after the cessation of activities will be provided as an addendum to this application upon determination of the total site disturbance. 9.3 Supplemental Industrial Performance Standards All operations will comply with applicable County, State, and Federal regulations for water, air and noise pollution and shall not be conducted in a manner constituting a public nuisance or hazard. Specific information about noise, heat, dust, etc. is provided in Sections 1 through 8. No flammable liquids or explosive solids or gases will be stored at the Cuttings Pit. All such materials will be properly stored at an appropriate site in accordance with the site Spill Prevention, Control, and Countermeasures (SPCC) plan. No outdoor storage, including heavy equipment, will be allowed at the Cuttings Pit location. All storage will be maintained at the service pads until the Office / Shop / Warehouse / Laydown Yard area is constructed. No repair operations will be allowed at the Cuttings Pit location. All repairs will be completed at the drilling or service pads. All loading / unloading operations will occur within the Cuttings Pit footprint. None of these types of operations will affect traffic on CR 211. Chevron North American Exploration and Production Company Cuttings Pit Special Use Permit Piceance Basin Non -Conventional Gas Project 29021-003 8 Document No: 006-31-14-01 No alcohol or firearms will be permitted at the Cuttings Pit or any other CNAEP facilities / property. Outdoor smoking areas will be designated at safe distances from any potentially flammable materials.

This SWMP addresses construction activities associated with development of the natural gas resources in the Skinner Ridge area. This SWMP is intended to be periodically updated as needed to address planned developments, new disturbances, and other changes needed to manage storm water and protect surface water quality. 1.1 Storm Water Runoff Permitting Requirements The Federal Clean Water Act [Section 402(p)] requires that discharges of pollutants to waters of the United States from any point source be regulated by NPDES permits. In November 1990 the USEPA published final regulations that established application requirements for storm water associated with construction activity for soil disturbances of 5 acres or more be regulated as an industrial activity and covered by an NPDES permit. In December 1999 the USEPA published final Phase II NPDES regulations that established application requirements for storm water associated with construction activity for soil disturbances to be regulated as an industrial activity and covered by an NPDES permit. These regulations became effective July 1, 2002. On June 30, 2005, the State of Colorado stormwater regulation went into effect to require Colorado Discharge Permit System (CDPS) permits from the Water Quality Control Division (the Division) for stormwater discharges from construction activities associated with small construction activity for oil and gas sites (those that disturb between one and five acres). Permitting for oil and gas construction sites that disturb five or more acres during the life of the project, or are part of a larger common plan of development, has been required since 1992. Although federal permit coverage for these discharges was conditionally exempted from the Federal Clean Water Act by the 2005 Federal Energy Bill, the Colorado Water Quality Control Commission has maintained the requirement within Colorado's regulations, and therefore permit coverage for these activities remains in effect in Colorado. These requirements are in addition to the requirements of the Colorado Oil and Gas Conservation Commission (COGCC). Construction permits are required for oil & gas activities that disturb 1 or more acres during the life of the project or are part of a larger common plan of development. CDPHE considers a common plan of oil and gas development to mean development of several well pads and/or related infrastructure in a contiguous area either during the same time period or under a consistent plan for long-term development. 3 SKINNER RIDGE SWMP CHEVRON U.S.A., INC 1.2 Project Description and Background The Skinner Ridge Common Plan of Development will be located in Garfield County, Colorado within Townships 5, 6, 7, 8 & 9 South, Ranges 97 & 98 West. The town of Debeque, Colorado is the nearest population center. The Skinner Ridge area is located approximately 14 miles north of DeBeque. The current drilling and development plan includes pad construction, access road improvement/construction, pit construction, installation of associated facilities, well drilling, well completion, well testing and pipeline construction. The area of disturbance including the natural gas well pads, the access roads and gathering system pipeline will be greater than twenty-six acres. 1.3 Project Owner and Operator The property owner and operator is Chevron U.S.A., Inc. Their address is: Chevron U.S.A. Inc. 11111 S. Wilcrest Houston, Texas 77099 Ph (281) 561-3664 The Chevron contact person for the project is Michael DeBerry, Manager, Piceance Basin Operations. Mr. DeBerry can be contacted by phone at 970-257-6005. The Chevron administrator for the Storm water Management Plan (SWMP) is Hector E. Cavazos. Mr. Cavazos can be contacted by phone at (281) 561-3664. Chevron will be in charge of all aspects of this project. Contractor(s) will be employed for construction and drilling, but all work will be supervised by Chevron and all decisions will be made by Chevron. 4 SKINNER RIDGE SWMP CHEVRON U.S.A., INC 2.0 CONSTRUCTION SITE DESCRIPTION 2.1 Site Location and Construction Area Description The Skinner Ridge project area will be located in Garfield County, Colorado within Townships 5, 8 & 9 South, Range 97 West and Townships 5, 6 & 7 South, Range 98 West. In areas that are disturbed by construction, soil materials will be managed so that erosion and sediment transport are minimized. Nearby drainages will be protected by appropriate measures. The road will be graded and sloped to drain into roadside ditches and to direct runoff from adjacent slopes away from the road surface. The development consists of the construction of roads, pipelines, drilling pads and gas treatment facilities. The construction of the facilities in the development area will be done using conventional cut and fill, trenching and earth moving techniques. Reclamation and final stabilization will be conducted as described in Section 7. 2.2 Schedule of Construction Activities Natural gas exploration and development activities are planned for several years. Existing and future well pads and other disturbances are included in this SWMP. For well pads that will be constructed, Best Management Practices (BMPs) will be installed prior to, during, and immediately following constriction. Development of the natural gas resource and construction of necessary improvements on this property will Iikely continue for the next 3 to 5 years. The development of natural gas wells is generally accomplished in three distinct work phases. The first phase is the Development (Construction/Drilling/Completion), the second phase is the Production (Operation/Maintenance), and the third phase is the Final Reclamation. Each work phase is briefly discussed below. Development (Construction/Drilling/Completion/Reclamation) The development phase includes the following activities; pad construction, well drilling, well completion, gas line installation, and pad area reclamation. Pad reclamation is accomplished by backfilling the reserve pit, contouring disturbed soils to conform with the surrounding terrain, replacing the stockpiled top soil, seeding of disturbed soil areas in order to reestablish a cover vegetation, and construction of erosion and sediment control structures. The completion of the wells (gas production) generally triggers a one - 5 SKINNER RIDGE SWMP CHEVRON U.S.A., INC year time period in which the reclamation phase of work should be completed. For the specific final stabilization seed mixture please refer to the Figure 2. Production (Operation/Maintenance) The production phase includes the operation and maintenance activities during natural gas production. The typical equipment on a pad during the production phase consists of a wellhead, a separation unit, from one to several 300 -barrel capacity aboveground tanks for condensate, and an above ground tank for storing produced water. Gas pipelines are also installed during this phase of work. Reclamation activities during this phase include maintenance of revegetated areas and maintenance of the erosion and sediment control structures. Natural gas wells in the Skinner Ridge area are projected to produce for approximately 20 to 30 years. Final Reclamation The pad area will be reclaimed by contouring disturbed soils to conform to the surrounding terrain, by replacing the stockpiled top soil, by seeding of disturbed soil areas in order to reestablish cover vegetation, and by construction of erosion and sediment control structures as needed. If the exploratory holes yield economically viable natural gas resources; additional gas well drilling will proceed. Once the well is completed and brought into production it will operate as an unmanned facility twenty-four hours per day, seven days per week, and 365 day a year. Chevron personnel or contract personnel will visit the site daily or at a minimum one per week. Once stabilization is achieved, defined as uniform vegetative cover established with a density of at least 70 percent of pre -disturbance levels, a well pad may be removed from this SWMP for sediment controls. Best Management Practices will stay in effect as an ongoing company practice to insure proper management of storm water protection. However, if petroleum hydrocarbons or other chemicals impact stormwater as a result of industrial activities onsite, the impacted stormwater will be addressed by following a spill prevention control and countermeasures (SPCC) plan. 2.3 Runoff Characteristics Runoff characteristics are based on site topography, soil type, and soil/vegetative cover. According to the NCRS, soils for the Skinner Ridge project area consist of the following soil types: 1. Biedsaw-Sunup gravelly loarns, 10 to 40% slopes -- is on side slopes of mountains and ridges. Native vegetation is mainly juniper, sagebrush, shadscale saltbrush, greasewood, ephedra, yucca, and Indian ricegrass. Elevation is 5,100 to 6,600 feet. Biedsaw soil is 6 SKINNER RIDGE SWMP CHEVRON U.S.A., INC deep and well drained. Permeability is slow and water capacity is high. Runoff is rapid and water erosion is severe. Sunup soil is shallow and well drained. Permeability is moderate and water capacity is very low. Runoff is rapid and water erosion is severe. 2. Cumulic Haploborolls, 1 to 3% slopes are on flood plains. Vegetation is narrowleaf, cottonwoods, maples, willows, grasses, and forbs. Elevation is 5,800 to 7,400 feet. The soil is deep and is well drained to poorly drained. Permeability is moderate to moderately slow and water capacity is low to high. Runoff is slow and water erosion is slight. 3. Grobutte very channery loam, 30 to 60% slopes — is on steep hills and mountainsides. Native vegetation is shrubs and grass. Elevation is 6,000 to 8,000 feet. The soil is deep and well drained. Permeability is moderately rapid and water capacity is low. Runoff is rapid and water erosion is very severe. 4. Happle very channery sandy loam, 12 to 25% slopes is on alluvial -colluvial fans and toeslopes. The soil is deep and well drained. Native vegetation is sagebrush, grasses, and forbs. Elevation is 5,400 to 6,200 feet. Permeability is moderate and water capacity is low. Runoff is medium and water erosion is severe. 5. Happle-Rock outcrop association, 25 to 65% slopes is on side slopes and canyon rims. The soil is deep and well drained. Native vegetation is sagebrush, grass, and forbs. Elevation is 6,200 to 7,200 feet. Permeability is moderate and water capacity is low. Runoff is rapid and water erosion is severe. 6. Tosca channery loam, 25 to 80% slopes — is on mountain side slopes and footslopes. The soil is deep and well drained. Native vegetation is serviceberry, Gat -label's oak, snowberiy, and grasses. Elevation is 6,200 to 8,500 feet. Permeability is moderate and water capacity is low. Runoff is rapid and water erosion is very severe. The runoff coefficient value prior to and after construction will range from 0.10 to 0.40; depending on the topography of each well pad. The pre -disturbance percent ground cover ranges from 60 to 85 percent. For specific pad percent ground cover information please refer to the plat maps. Possible receiving waters include unnamed tributaries of Tom Creek, Deer Park Gulch, Clear Creek, Roan Creek, and the Colorado River. 7 SKINNER RIDGE SWMP CHEVRON U.S.A., INC 3.0 POTENTIAL POLLUTION SOURCES Potential pollution sources associated with construction sites and natural gas development include: • Sediment resulting from erosion of soil stockpiles and other areas cleared of vegetation; • Leakage of fuels and lubricants from equipment and spills from fueling; • Trash and debris from clearing activities, construction materials, and workers; • Leakage or spills from storage tanks and process equipment associated with natural gas development. The most common source of pollution from pad and access road construction is sediment, which can be carried away from the work site with storm water runoff and impact the water quality of a receiving stream. Clearing, grading, and otherwise altering previously undisturbed land can increase the rate of soil erosion over pre -disturbance rates. Refined Petroleum products can also be potential storm water pollutants. These products are used in construction activities to power or lubricate equipment and include: fuel, gear oil, hydraulic oil, brake fluid, and grease. Debris from laydown areas, residue from equipment cleaning and maintenance, and solid waste generated from land clearing operations and human activity (trees, brush, paper, trash, etc.) present other potential pollution sources within the construction site. Spills or leaks from potential sources are described in the SPCC plan. Response to certain events may require specialized training due to health and safety concerns. 8 SKINNER RIDGE SWMP CHEVRON U.S.A., INC 4.0 DESCRIPTION OF CONTROL MEASURES 4.1 Soil Erosion and Sediment Controls The objective of erosion and sediment controls is to minimize the release of sediments to storm water runoff. This can be accomplished through the use of structural and/or nonstructural controls. This section describes erosion and sediment controls to be used at active construction sites to minimize possible sediment impacts to storm water runoff. The proposed erosion control features can include but not limited to: • Placement of any topsoil stockpiles along the cut -slope side of the pad to divert run-on; • Installation of silt fence, straw bales or diversion ditches at or below the toe of fill slopes where located within 100 feet of surface water drainages or where steep slopes will likely result in rapid drainage from the location to nearby drainages, and; • Installation of check dans in areas of concentrated flow; • Use of erosion control matting, rock armoring, and soil berms to prevent soil erosion. 4.1.1 Uphill topsoil stockpile/diversion berm In order to divert surface runoff from upgradient areas away from construction areas, salvaged topsoil may be placed on the uphill side of the road cut slope. The topsoil stockpile may be placed and graded to form a diversion berm that will direct surface water away from the road. 4.1.2 Downhill silt fence Silt fence can be installed at the down gradient edge of the road and other fill slopes located within 100 feet of a surface drainage. Silt fences may also be required in areas where steep slopes will likely result in fast flow of water from the location to nearby drainages. Typical silt fence installation details are given in Appendix B. 4.1.3 Hay bale check dams Hay bale check dams should be installed at suitable locations to slow the concentrated flow of drainage water. Typical hay bale check dam installation details are given in Appendix B. 9 SKINNER RIDGE SWMP CHEVRON U.S.A., INC 4.1.4 Rock check dams Rock check dams will be installed in areas of concentrated flow. Rock check dams may be used instead of hay bale check dams in areas where steep slopes, high flows, or long- term exposure are expected to result in failure or frequent maintenance of a hay bale structure. Typical hay bale check dam installation details are given in Appendix B. 4.1.5 Road drainage relief Culverts, rolling dips or water bars may be used to provide drainage of water from road surfaces as needed to drain low areas or to reduce the amount of water flowing on the road surface. Road drainage relief should be provided as needed and in accordance with generally accepted practices. Guidance for road drainage relief is available in the document "Low -Volume Roads Engineering, Best Management Practices Field Guide," developed by the U.S. Forest Service and available on-line at http://www.blm.gov/bmp/field%20guide.htm. Depending on the location and type of drainage relief installed, additional sediment control features may be needed such as sediment removal at the inlet and erosion protection at the outlet. 4.1.6 Culvert inlet and outlet protection Installation of culverts may be needed in certain areas where the access road intersects intermittent drainages. The culvert inlet area will include a sediment sump. The culvert outlet area will include an energy dissipation feature that should be installed to promote lateral spreading of the water. 4.1.7 Soil berm Soil berms may be used to divert drainage away from areas of concern or to direct flow toward sediment control structures. Where used, soil berms shall be constructed of soil with sufficient fines to minimize flow through the berm. Berms shall be at least 1 8 - inches tall and will be compacted in place by wheel rolling with suitable rubber tired, heavy equipment. 4.1.8 Straw waddles Straw rolls are intended to capture and keep sediment on the slopes. Straw rolls are useful to temporarily stabilize slopes by reducing soil creep and sheet and rill erosion until permanent vegetation can be established. Straw rolls will last an average of one to two years. The slope needs to be prepared before the rolls are placed. Small trenches are created across the slope on the contour. The trench should be deep enough to 10 SKINNER RIDGE SWMP CHEVRON U.S.A., INC accommodate half the thickness of the roll (about 3"-5"). The trenches need to be 10 to 25 feet apart. The rolls need to be installed perpendicular to water movement, parallel to the slope contour. Start by installing rolls from the bottom of the slope. The rolls need to fit snugly against the soil. No gaps should be between the soil and roll. Willow or wooden stakes need to be driven through the roll and soil. There should only be 1 to 2 inches of stake exposed above the roll. The stakes should be installed every 4 feet. 4.1.9 Seeding of disturbed areas Project areas disturbed by construction will be revegetated as soon as practicable following construction. Areas that will be revegetated will primarily be cut and fill slopes associated with grading activities. The permanent mix, rate, application method, and supplemental materials will be selected by the revegetation contractor. It is anticipated that this will include suitable grass species supplemented by cereal crops. 4.1.10 Rocky areas In areas of the project, the depth to bedrock is expected to be relatively shallow. Excavation in these areas will result in rock fragment and pieces being exposed on the ground surface. Rock pieces, typically sedimentary sandstone, siltstone or shale, will provide a surface that is erosion resistant. Both cut and fill slopes in rocky areas may result in a surface that is similar to gravel surfacing (see below) and depending on the extent of rock pieces may preclude the use of downstream sediment retention BMPs (such as berms or silt fence). The person selecting BMPs should use experience and good judgment in determining which rocky soils will or won't require downstream BMPs. 4.1.11 Gravel surfacing Gravel surfacing may be used to cover soil in areas of high traffic such as roads, facility areas, and the area near well heads. Gravel surfacing forms a layer that protects soil from wind and water erosion and prevents vehicle tracking. 4.1.12 Natural vegetative cover An effective way to prevent erosion and sedimentation is to preserve the existing vegetation. It can provide both dust control and a reduction in erosion potential by increasing infiltration, trapping sediment, stabilizing the soil, and dissipating the energy of hard rain. Natural vegetative cover can be applied to any site and is not restricted by the type of soil, topography or climate. 11 SKINNER RIDGE SWMP CHEVRON U.S.A., INC 4.1.13 Sediment basins A sediment basin is a way to capture sediment from stormwater runoff before it leaves a development site. The basin will allow storm water runoff to collect in a basin, where the sediment can settle. Sediment basins must be located in an area that is easily accessible to maintenance crews for removal of accumulated sediment. 4.1.14 Diversion ditch Diversion ditches convey concentrated runoff of surface water from the areas of disturbance to a stabilized area. The ditch should be excavated to a depth and width that can handle the expected flows. The ditch should be sloped so that the water velocities do not cause excess erosion. The ditch can be lined with check dams, vegetation, rock and/or other filter BMPs. 4.1.15 Erosion control matting Erosion control matting is a way to provide erosion protection and assist in the establishment of vegetation. The matting selection should be based on the slope ratio. Typical erosion control matting installation details are given in Appendix B. 4.1.16 Additional BMP references The structural and non-structural BMPs listed above are intended to include all BMPs that may be used for gas gathering projects. However, there may be situations where a BMP is needed but not included above or project personnel may need additional information on the use, specification, and maintenance of BMPs. Additional information resources are listed below: • For oil and gas operations, the Bureau of Land Management and U.S. Forest Service have developed "Surface Operating Standards and Guidelines for Oil and Gas Exploration and Development," "Gold Book." The most recent version (fourth edition) of this is available on the internet at http://www.blm.gov/bmp/GoldBook_Draft v12.pdf. • For construction BMPs the Urban Drainage and Flood Control District, a Colorado front range group of city and county agencies has developed a BMP manual that is available on the internet at http://www.udfcd.org/usdcm/vol3.htm • For construction BMPs and surface stabilization methods, the Alabama Soil and Water Conservation Committee has developed "Erosion Control, Sediment Control and Stormwater Management on Construction Sites and Urban Areas, Volume 1 Developing Plans and Designing Best Management Practices." This information is available on the internet at 12 SKINNER RIDGE SWMP CHEVRON U.S.A., INC http://swcc.state.al.us/pdf/ASWCC June 2003 Alabama Handbook Constructio n_E&S Control.pdf • For access roads, the US Forest Service and Bureau of Land Management have developed "Low -Volume Roads Engineering, Best Management Practices Field Guide," which is available on the internet at http://www.bhn.gov/brnp/field%20guide.htm 4.2 Storm Water Management Controls Stnictural BMPs will be installed, inspected, and maintained as needed. This SWMP will be revised as needed to address new disturbances. Depending on the type and location of new facilities there may be a need for inclusion of new and different BMPs. In general, new development should be planned with consideration for storm water quality (e.g. minimize disturbed area and maximize distance from surface water drainages, as practicable). Other developments on the property, primarily existing and/or improved roads, not currently or specifically addressed in the SWMP will be periodically checked for erosion and drainage problems. This is especially important for access roads located within 100 feet of surface drainages or creeks. If problems are noted, they should be reported to the Operations Supervisor and/or Chevron SWMP administrator. Problem areas may be addressed through construction activities, but will likely need to be addressed through BMPs which will be added to the plan as needed. 4.3 Other Controls 4.3.1 Waste management and disposal Pad and access road construction will generate various other wastes during the course of construction. Other wastes may include the following: • Trees and shrubs from clearing operations, • Trash and debris from construction materials and workers, • Sanitary sewage. Each of these wastes will be managed so as to not contribute to storm water pollution. Trees and shrubs may be piled along the toe of fill slopes to provide additional sediment control. Construction trash and debris will be collected in containers and hauled off-site for disposal in approved landfills. Sanitary waste will be containerized in portable toilets or other storage tanks with waste materials regularly pumped and transported off-site for disposal at approved facilities. 13 SKINNER RIDGE SWMP CHEVRON U.S.A., INC 4.3.2 Fuels and materials management Petroleum Products Petroleum products which may be present at the construction site include but not limited to: gasoline, diesel fuel, lubricant oils, hydraulic oils, used oils, and solvents. Gasoline and diesel fuel will be stored in portable storage tanks with secondary containment. Lubricant, hydraulic, and miscellaneous oils and solvents will be stored in 55 -gallon or smaller containers. Pollutants from petroleum products used during construction activities adhere easily to soil particles and other surfaces. In case of a spill or leak, soils contaminated with petroleum products will be contained and removed to an approved disposal site. Proposed soil erosion and sediment control practices will aid in retention of spills or leaks. Use of secondary containment and drip pans/sorbent materials will reduce the likelihood of spills or leaks contacting the ground. Proposed maintenance and safe storage practices will reduce the chance of petroleum products contaminating the road site. Oily wastes such as crankcase oil, cans, rags, and paper containing oils will be placed in proper receptacles and disposed of or recycled. An additional source of petroleum contamination is leaks from equipment and vehicles. Routine daily inspections will be conducted to identify leaks and initiate corrective actions, if needed. The local SPCC plan will be activated as appropriate to manage any petroleum product spill. The following guidelines for storing petroleum products will be used. • All product containers will be clearly labeled. • Drums will be kept off the ground within any required secondary containment and stored under cover if needed. • Fuel tanks will be stored within any required secondary containment. • Lids of drummed materials will be securely fastened. • Emergency spill response procedures will be available on-site. Persons trained in handling spills will be on call at all times. • Spill clean up and containment materials (absorbent, shovels, etc.) will be easily accessible. Spills will be immediately cleaned up and contaminated materials will be properly stored on site until they can be disposed of in accordance with applicable regulations. • Storage areas and containers will be regularly monitored for leaks and repaired or replaced as necessary. Workers should be reminded about proper storage and handling of materials during weekly subcontractor or safety meetings Other Chemicals Products Management Additional materials will be used and stored on site for use in construction. These materials will be stored appropriately and managed to minimize spills and Leaks. Storage areas will be regularly inspected and any minor spills or leaks will be cleaned up immediately. 14 SKINNER RIDGE SWMP CHEVRON U.S.A., INC Materials Management The construction contractor will maintain a laydown or staging area for equipment and materials storage on site. These areas will be maintained with good housekeeping and will be inspected on a regular basis for spills, leaks, and potential contamination. 4.3.3 Construction Site Housekeeping Housekeeping will consist of neat and orderly storage of materials and containerized fluids. Wastes will be temporarily stored in containers and regularly collected and disposed of at approved off-site facilities. If spills occur prompt cleanup is required to minimize any commingling of waste materials with storm water runoff. Routine maintenance will be limited to fueling and lubrication of equipment. Drip pans and/or sorbent material will be used during routine fueling and maintenance to contain spills or leaks. Any waste product from maintenance will be containerized and transported off site for disposal or recycling. All attempts will be made to minimize major equipment overhauls conducted on site. Equipment will be transported off site for major overhauls if required. Cleanup of trash and discarded materials will be conducted during the course of each work day. Cleanup will consist of patrolling the road way, access areas, and other work areas to pickup trash, scrap debris, other discarded materials, and any contaminated soil. These materials will be disposed of appropriately. 15 SKINNER RIDGE SWMP CHEVRON U.S.A., INC 5.0 INSPECTION AND MAINTENANCE PROCEDURES To meet requirements of the General Permit inspection and maintenance of erosion and sediment controls must occur during the project. Continued inspection and maintenance is required for specific structures after construction is completed. The inspection program will include the following: 1. A qualified person familiar with the SWMP and control measures will conduct the inspections. 2. Inspections will cover these area of the construction site: • Disturbed areas without stabilization, • Material storage areas, • Best Management Practices (BMPs), • Surface water diversions, • Downgradient areas, • New access roads, and • Locations where vehicles enter or exit the site. 3. Inspections will occur at least once every 14 calendar days and after a significant precipitation or snow melt event that causes erosion; depending on safety concerns. 4. Completed and stabilized sites will be inspected at least once per month; depending on safety concerns. 5. A log of inspections will be kept. 6. Water quality will be assessed for all receiving streams and discharge areas 7. Disturbed areas and material storage areas that are exposed to precipitation will be inspected for evidence of pollutants entering nearby drainages. 8. Check dams, silt fences, and/or other BMPs will be inspected for evidence of deterioration, under -cutting, and build up of sediment. Sediment will be removed as required. 9. Roads used for vehicle access will be inspected for evidence of off-site sediment transport. 10. The SWMP will be modified as necessary to include additional controls designed to correct identified problems. Approved revisions to the SWMP will be made within 7 days of the approval or sooner at the discretion of the Operations Supervisor. 11. An inspection report summarizing the scope of the inspection, the name of the person conducting the inspection, date of inspection, and observations relating to the implementation will be prepared. Inspection reports will be retained for at least 3 years from the date that the site is finally stabilized. 12. Actions taken to modify any storm water control measure will be recorded and maintained with the SWMP. 13. If no deficiencies are found during the inspection, the report will contain certification that the site is in compliance with the SWMP. Signatures will be in accordance with the General Permit Conditions, Part E. 1 (Appendix A). 16 SKINNER RIDGE SWMP CHEVRON U.S.A., INC Maintenance will include prompt repairs and/or adjustments to any erosion and sediment control structures that are deteriorating or found to be performing inadequately. Repairs should be made as soon as possible and prior to the next inspection or anticipated storm event. Chevron U.S.A. or designated contractor(s) will maintain, on-site all materials necessary to make any reasonably expected repairs such as silt fence, hay bales, and stakes. 17 SKINNER RIDGE SWMP CHEVRON U.S.A., INC 6.0 NON-STORMWATER DISCHARGES No non -storm water discharges are anticipated from the project.

For the specific final stabilization seed mixture please refer to Figure 2. Areas at which are not used for facilities, access roads, materials storage yards, or other work areas will be stabilized with vegetation. Areas that are stabilized with vegetation will be considered to have achieved final stabilization when a uniform stand of vegetation with a density of at least 70 percent of the pre -disturbance has been established. Other areas which may include facilities, access roads, materials storage yards, and other work areas will be considered fully stabilized with the use of permanent, physical erosion reduction methods which include, but are not limited to: 1. Surface hardening — covering of the soil surface with hardened products such as concrete or asphalt pavement. 2. Surface covering — covering of the surface soil with structure that inhibits contact of precipitation with the soil surface which is generally considered to be placement of a structure (building or tank) over the soil surface. 3. Gravel surfacing — gravel surfacing will be applied in areas such as access roads, materials storage yards, and other work surfaces. Some gravel may be lost due to erosion from intense precipitation events or due to vehicle traffic. Gravel surfaces will be periodically inspected to determine the need for gravel replacement. Gravel surfaces will be replaced or repaired (through grading) when inspection reveals that the gravel surface is no longer effectively covering the soil surface. 19 SKINNER RIDGE SWMP CHEVRON U.S.A., INC 8.0 CERTIFICATIONS 8.1 Owner/Applicant Certification I certify under penalty of law that this document and all attachments were prepared under my direction or supervision in accordance with a system designed to assure that qualified personnel properly gather and evaluate the information submitted.

CHEVRON EXPLORATION & PRODUCTION CORPORATION MidContinent Business Unit Stormwater Guidance Document aliato 2006 Stormwater Permit (SW) Introduction: The 2005 Energy Rule has incorporated an exemption for oil and gas operations, including construction activities, at oil and gas exploration, production, processing or treatment operations or transmission facilities from the requirements to obtain an NPDES permit for stormwater discharges except in very limited instances. States may still choose to regulate construction stormwater runoff from your facilities, and Alaska, Colorado, Wyoming have indicated their intention to do so. This exemptions does not apply to any violation of a Reportable Quantity (RQ) that triggers a permit need for E&P operations. This exemption encourages voluntary application of best management practices (BMPs) for construction activities associated with oil and gas field activities and operations to minimize erosion and control sediment to protect surface water quality. MCBU standards always require the use of BMPs, regardless of proximity to water Disturbances: Criteria: The criteria that will initiate the permitting process for a Stormwwater Permit (SWP) will be determined by the amount of acreage that will be disturbed and the proximity to waters of the US or state. These disturbance areas include: Disturbed construction area — Drilling pads -- Storage or staging areas Access roads built or modified during this disturbance — Stockpile areas — Right of Ways for pipelines and/or electrical distribution systems Acreage size: The acreage size noted below does not apply in all states except Alaska, Colorado, and Wyoming. There is no regulatory requirement to develop storm water plans prior to commencing operations in all other states. There is however a MCBU guideline to use best management practices (BMP) in all 8/24/2007 construction activities to insure adequate environmental safeguards are in place to prevent any storm water runoff. In Alaska, Colorado, Wyoming, the size of the disturbance will dictate the required action and the level of detail required to comply with federal and or state requirements. The acreage will fall into three categories - < 1 acre (less than one acre) - > 1 acre < 5 acres (greater than one acre and less than five acres) - > 5 acres (greater than five acres) Inspections: Inspections will be performed during, and after any construction activity in Alaska, Colorado, and Wyoming. Inspections (attached) will be documented and filed in the field office for any state and/or federal agency review. Photographs of the identified construction site will be taken prior to any disturbance. These photos will be used to compare the site for full stabilization and closure of the permit Active construction site -- inspection performed every fourteen days (14) days and after a one half (1/2) inch rainfall and snowmelt event. Inspections will be performed by the Facilities Engineering group during the active construction activity. These inspections will be performed by the construction representative. Post construction - inspections performed monthly until site is 70% fully stabilized . The Operations Group will perform the inspections on the post construction site. These inspections will be performed by the lease operator or operation supervisor designated personnel. The D7i program will be used to schedule the 14 day and monthly inspections and insure full compliance with the storm water inspection requirements. DocMan can also be used in those areas that use DocMan to record all documented inspections, Storni water prevention plans, and permits. Training: Training for detailed understanding of the SWP process within MCBU can be accessed through the training coordinator. 8/24/2007 Storm Water Pollution Prevention Plan Drilling/Construction Activity Field/Project: Is this a required bi-weekly or monthly inspection?

Emergency evacuation route(s), places of refuge, assembly point(s), and the locations of key site emergency equipment are identified on this map. Major topographical features and the direction of prevailing winds/weather conditions that could affect emergency response planning are also marked on this map. Figure 7-3a is pasted at site entry points and at locations Throughout the work area. 7.4 Roles and Responsibilities for On -Site and Off -Site Personnel The Project Supervisor is responsible for implementing the emergency response plan and coordinates emergency response activities on this site. Helshe provides specific direction for emergency action based upon information available regarding the incident and response capabilities and initiates emergency procedures, including protection of the public and notification of appropriale aulhOrilies. In the event of an emergency, site personnel are evacuated and do not participate in emergency response activities. Asa result. this emergency response plan is designed 10 COM ply with 29 CFR 1910.38(a). The on- site personnel and their alternates responsible for coordinating site evacuation efforts am listed in Table 7-4, The site relies upon the off-site emergency response organizations listed in the Emergency Contact Information, Table 7-4, to respond to site emergencies. 7.5 Emergency Alerting and Evacuation Site workers are alerted to emergencies Through the use of an employee alarm system. The employee alarm systems at this site are listed in Table 7-5. Table 7-5 Employee Alarm Systems Type of Alarm Location How Alarm is Used Air horn Sso Three blasts This alarm system is tested periodically under normal site operating conditions to ensure that it is in good working order and can effectively alert all persons on-site, If evacuation notice is given, site workers leave the worksite by way of the nearest exit, Appropriate primary and alternate evacuation routes and assembly areas have been identified. The routes and assembly area will be determined by conditions at the time of the evacuation based on wind direction, the location of the hazard 50ur0e. and other factors as determined by rehearsals and inputs from emergency response organizations. Wind direction indicators are located so That workers can determine a safe up wind or cross wind evacuation route and assembly area if not informed by the emergency response coordinator at the time the evacuation alarm sounds. Personnel exiting the site gather at a designated assembly point To determine that everyone has successfully exited the site, personnel will he accounted for at 1110 assembly site. If any worker cannot be accounted for, notification is given to the Project Supervisor so that appropriate action can be initiated. Contractors and subcontractors on this site have coordinated their emergency response plans to ensure that these plans are compatible and that source(s) of potential emergencies are recognized, alarm systems are clearly understood, and evacuation routes are accessible to all personnel relying upon them. 7.6 Emergency Response When the lead person on site determines that outside assistance is required, the applicable off-site organization Shown in Table 7-4 is Contacted. They provides relevant information to the responding Organizations, including hazards associated with the emergency incident, potential containment problems, and missing site personnel. 7.7 Emergency Medical Treatment and First Aid This Site does not assign site personnel to provide first aid. Personnel who require medical care are transferred to a medical facility. Some personnel on site will be trained in basic first aid and will render care to the best of their abilities under the "Good Samaritan" laws. 7.8 Emergency Response Training All persons who enter this worksite, including visitors, receive a site-specific bnefrng about anticipated emergency situations and the emergency procedures. Prior to the commencement of work and in accordance with the Training Section of this Plan, site personnel are trained in the contents of this emergency response plan, including potential emergencies, personnel 10105 and responsibilities, evacuation routes and procedures, and the location of medical assistance_ WhereThis site relies on off-site organizations for emergency response (see Table 7-3), the training of personnel in those off-site organizations has been evaluated and is deemed adequate for response to This site. 7.9 Emergency Response Fire Management We will minindze the nsk of accidental fire by utilizing the following mitigation measures as applicable for the site. Stectly adhere to Hol Work Procedures and protocols Control noxious weeds and cheatgrass Inspect and maintain equipment to minimize potential ignition sources Use spark arrestors on engines where applicable Carry incipient stage fire fightng equipment (up to 204 ABC extnguisher) in vehicles and they (334 ABC extinguishers) will be staged on ail pad locations • Individuals will be trained in Incipient stage fire fighting techniques and will respond according to their training to Suppress any accidental fires Will create defensible Spaces in line with the Colorado Firewise Guidelines and in line with SLM Fire Management Guidelines Figure 73 Primary Muster Point: Hiner Gate (N39 Deg 32.474 W 108 Deg 19.518 Elevation 5839) Alternate Muster Point: Cowboy Chapel (N39 Deg 29,115 ft.

Fire Prevention and MCA Business Unit Protection Guidelines Piceance Basin Safety Plan, Hot Work Permitting Procedures May 2007 SCOPE The scope of these guidelines is to outline some basic principles to avoid the potentials of having an unplanned and out of control fire, while setting some protection mechanisms in place in case it occurs REQUIREMENTS Chevron requirements are set forth to do all in our powers to avoid the potentials of starting an unplanned fire and all individuals will he trained to know what to do and when to do it if the occasion occurs. APPLICABLE DOCUMENTS Safety Plan, Hot Work Permitting Procedures MATERIALS & EQUIPMENT Permits, Fire Extinguishers, Water sources SAFETY Individuals will be trained to allowable response levels, and all care will be taken to avoid a human caused event. Personnel will be given these guidelines to aid them in occasions of nature caused events also. QUALITY These Guidelines will be reviewed periodically and will be shared with employees. During Level III and other audits we will question field workers to insure they have adequate knowledge to protect themselves in an emergency situation. Task 1.0 Fire Prevention Sub Task 1.1 The field production and processing units will be designed to minimize the potential for starting fires. This includes but isn't limited to; • Flare Stacks • Fired Vessels • Heater Packages • Incinerators 1.2 All work that has potential to cause an ignition source to a combustible material will be covered and planned for using a JSA and Hot Work Permit following the local protocols. • JSA should include weather conditions, and fire potential. BLM Website has this updated daily. • Contact local response personnel and notify them a head of time when doing certain actions that raise the hazards. • Emergency Response Plan will be discussed during JSA meetings • Insure all information is included on the JSA and shared with all personnel affected by the job.

This area won't be completely void of vegetation due to storm water damage potentials, but will be kept at a reasonable low level. 1.4 Fire Breaks will be mowed into the local landscape to help eliminate fire spread potentials. These areas won't be devoid of vegetation, but will have it kept at minimal levels to avoid fire potentials and addressing storm runoff problems. 1.5 Where applicable we will try to replace the cheat grass, purple mustard, sagebrush, and scrub brush with plants that are less conducive to wildfire spread. 1.6 Vehicle traffic will be restricted to maintained roads only (unless the person has written approval from Chevron Management). This reduces the potential of a fire being started by the catalytic converter. 1.7 Smoking will be restricted to certain locations in our field that are appropriately set up for disposal of the cigarette wastes. No smoking in vehicles or out in the open because of the wildfire potentials. 1.8 Areas around Flare Stacks and Fire vessels will be maintained as bare ground and treated to avoid fire potentials. In some cases other actions will be required to eliminate storm runoff and erosion potentials. 1.9 Work with the BLM and if they see an opportunity to do a prescribed burn to eliminate some fire dangers work with them to make sure it's done safely and with minimal effect on our actions. 2.1 Chevron Employees will be trained to fight Incipient Stage Fires only. • A fire that can be controlled with in 3 minutes or less with use of a small water hose, shovels, polaski, or fire extinguisher. 2.2 Fire Extinguisher will be strategically located at the well sites, in process areas, or in the personnel's vehicles for response capabilities. 2.3 Actions • Make sure you are in a safe location • Notify others of problem and get help corning • Fight fire if you determine it is in incipient stage Printed 8/27!2007 9:07:50 AM Page 2 Chevron Production Co.

December 2006 Chevron Clear Creek 8 Inch Pipeline IVNWMP Page 1 of 14 Chevron Clear Creek 8 Inch Pipeline Integrated Vegetation and Noxious Weed Management Plan December 2006 Introduction On November 22, 2006, a field inspection of the subject pipeline was conducted by WestWater Engineering (WWE) biologists. The inspection identified appropriate topics for inclusion in an integrated vegetation and noxious weed management plan required by Garfield County Regulation 9.07.04 (13) (BOCC, 2006). Factors considered include soil type and texture, existing land management, absence or presence of listed noxious weeds and likely potential natural vegetation community. Landscape Setting Chevron Clear Creek 8 Inch Pipeline is on the first terrace above Clear Creek and generally follows the creek and road in a southeasterly direction before turning west and climbing the slopes of Mt. Blaine. At the northern terminus, Clear Creek was dry on the date of inspection (Photo 2). Southeast of the northern terminus a few hundred meters, high quality groundwater springs commence surface flow. The stream is lined with watercress, Nasturtium officinale with a heavy riparian deciduous shrub and woodland over story comprised of mountain boxelder, Acer negundo and introduced and naturalized New Mexico locust, Robinia neomexicana (Photo 3). The New Mexico locust has crowded out most native shrubs one would expect such as skunkbush sumac (Rhus trilobata) and willows (Salix spp.). Photo 2. Dry stream bed near north terminus. Photo 3. Clear Creek flowing near mid -point. Terrain is gently sloping to moderately steep. Soils on the pipeline route are cumulic haploborolls in the meadow -forming swales and fans along the creek, Happle very channery sandy loam on moderately steep, brushy toe slopes, foot slopes, fans, and back slopes adjacent to the meadows and Biedsaw on the steep slopes where the route turns westerly to the southern terminus on the slopes of Mount Blaine. Texture of the meadow soil is very fine, sandy loam while the brushy Happle soils are variable but mostly medium texture sandy loans, deep, and well -drained with high permeability. The Biedsaw soil is clay loam or clay, but clay ranges from 35 to 45 percent, silt from 25 to 50 percent, and sand from 15 to 30 percent (NRCS, 2006b). WestWater Engineering Chevron Clear Creek 8 Inch Pipeline IVNWMP Page 2 of 14 Potential natural vegetation for meadows includes basin big sagebrush (Artemesia tridentata tridentata), western wheatgrass (Pascopyrurn smithii) and basin wildrye (Leymus cinereas). For moderate, loamy slopes, needle and thread (Hesperostipa comata comata), bluebunch wheatgrass (Pseudoroegneria spicatum spicatuna), Indian ricegrass (Achnatherum hymenoides) western wheatgrass, Wyoming big sagebrush (A. t. ia'yomingensis), and winterfat, (Krascheninnikovia lanata) is expected and was, to an extent, observed during the inspection by WWE. Similar vegetation on the steeper but still moderate, brushy slopes is expected with the Photo 4. Typical natural vegetation. Photo 5. Shrubland near turn to west. addition of bottlebrush squirreltail (Sitanion h>>strix) and shadscale saltbush (Ampler confertifolia). The westerly portion of the route across the slopes of Mount Blaine to the southern terminus has native vegetation dominated by Utah juniper (Juniperis utahensis), pinyon pine (Pinus edulis), western wheatgrass, bottlebrush squirreltail, and Wyoming big sagebrush Photo 1, cover). Current Amount of Infested Land Needing Treatment More than half the route for the pipeline is exposed to or infested with Garfield County and State of Colorado (8 CCR 1203-19) listed noxious weed species (Figure 1 and 2, p. 13 and 14). This is particularly true near Clear Creek along the edge of the deciduous riparian vegetation and meadows and where the pipeline crosses the creek. Species in bold type in Table I are Garfield County listed noxious weeds and the others are listed by the State of Colorado as noted. All invasive species observed were noted due to the adverse impact these species may have on reclamation. Additionally, some species not listed in Garfield County are listed in adjacent jurisdictions, e.g., common mullein. Only Garfield County listed weeds are trapped. Table 1.

Herbicides should not necessarily always be the first treatment of choice when other methods can be effectively employed. Table 2. Treatment Strategies for Annual and Biennial Noxious Weeds Target: Prevent Seed Production 1. Allow plants to expend as much energy from root system as possible, do not treat when first emerging in spring but allow growth to bud/bloom stage. If seeds develop, cut and bag if possible. 1. Hand grub (pull), hoe, till, cultivate in rosette stage and before flowering or seed maturity. seeds develop, cut and bag seed heads. If ^2. Chop roots with a spade below soil level. 5. Hand pulling is generally not recommended for perennial species unless you know the plants are seedlings and not established plants. Hand pulling can be effective on small patches but is very labor intensive because it must be done repeatedly. 3. Treat with herbicide in rosette or bolting stage, before flowering. 4. Mow biennials after bolting stage, before seed set. Mowing annuals will not prevent flowering but can reduce total seed production. Herbicide treatment with two or more herbicide modes of action in fall (after approximately August 15 when natural precipitation is present) is the best method to control difficult perennials such as Canada thistle. The resilience of Canada thistle and its 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. Table 3. Treatment Strategies for Perennials Target: Deplete nutrient reserves in root system, prevent seed production 1. Allow plants to expend as much energy from root system as possible, do not treat when first emerging in spring but allow growth to bud/bloom stage. If seeds develop, cut and bag if possible. 2. Herbicide treatment at bud to bloom stage or in the fall (recommended, after August 15 when natural precipitation is present). In the fall plants draw nutrients into the roots for winter storage. Herbicides will be drawn down to the roots more efficiently at this time due to translocation of nutrients to roots rather than leaves. If the weed patch has been present for a long period of time, another season of seed production is not as important as getting the herbicide into the root system. Spraying in fall (after middle August) will kill the following year's shoots, which are being formed on the roots at this time. 3. Mowing usually is not recommended because the plants will flower anyway; seed production should be reduced. Many studies have shown that mowing perennials and spraying the re -growth is not as effective as spraying without mowing. Effect of mowing is species dependent; therefore, it is imperative to know the species and its basic biology. Timing of application must be done when biologically appropriate which is not necessarily convenient. 4. Tillage may or may not be effective. Most perennial roots can sprout from pieces only 1/2" - 1" long. Clean machinery thoroughly before leaving the weed patch. 5. Hand pulling is generally not recommended for perennial species unless you know the plants are seedlings and not established plants. Hand pulling can be effective on small patches but is very labor intensive because it must be done repeatedly. 1've:>tVV tci Eriginocrine; Cl r. rcir Clear C;reelk 8 Inch Pipeline IVNWIVIP P_ gc 5 c,f Following any non-selective herbicide treatment (e.g. glyphosate), the entire treated portion should be replanted with a mix of grasses recommended in this plan. The seed mix of grasses does not include forbs or shrubs due to the presence of Canada thistle and field bindweed. Shrubs and native forbs and legumes are usually adversely affected by herbicides much as the weeds are affected. Shrub, forb and tree components of the vegetation community can be added after control of undesirable species has been attained. For example, in irrigated meadows, re- planting of the entire meadow with a mix of grasses and non -bloating legumes such as sainfoin, Onobiychis viciaefolia, followed by rest from grazing is recommended. Best Management Practices The following practices should be adopted for any construction project to reduce the costs of noxious weed control. The practices include: • top soil, where present, should be segregated from deeper soils and replaced as top soil on the final grade, • in all cases temporary disturbance should be kept to an absolute minimum, • equipment and materials handling should be done on established sites such as the northern point of origin, • disturbances should be immediately replanted with the recommended mix in the re - vegetation section. • WWE recommends moving the pipeline laterally to keep as much of the route in the meadows and out of the shrubs as possible. It is far easier to manage meadow vegetation than re-establish shrubs and forbs and control weeds in shrubs. In areas with slope greater than 3%, imprinting of the seed bed is recommended. Imprinting can be in the form of dozer tracks or furrows perpendicular to the direction of slope. When hydro - seeding or mulching, imprinting should be done prior to seeding unless the mulch is to be crimped into the soil surface. If broadcast seeding and harrowing, imprinting should be done as part of the hanowing. Furrowing can be done by several methods, the most simple of which is to drill seed perpendicular to the direction of slope in a prepared bed. Other simple imprinting methods include deep hand raking and harrowing, always perpendicular to the direction of slope. Herbicides: Difficult species respond better to application of a combination of two or more chemical modes of action (biological reason for plant death) rather than one. Local certified commercial herbicide applicators report best control of Canada thistle using a combination of modes of action. It has also been found that use of two different groups of chemicals in the same mode of action can increase effectiveness on difficult species, e.g. phenoxys and benzoic acids or carboxylic acids and benzoic acids in a mix. Some come commercially pre -mixed, e.g. Crossbow and Super Weed -be -Gone Max which are available over the counter. Some of the most effective herbicides are restricted use and available only for licensed applicators. Professionals or landowners using herbicides must use the concentration specified. Herbicides generally do not work better at higher concentrations. Most herbicide failures observed by 1'VcstWatcr Fngineori;id Chevfon Clea Creek 3 Inch Pipeline IVN /MP Faye 6 of 14 WWE are related to incomplete control caused by high concentrations killing top growth before the active ingredient can be transported to the roots through the nutrient relocation process. Most herbicide applications should use a surfactant as directed on the herbicide label or other adjuvants as called for on the herbicide label. Grazing: There is currently heavy grazing on much of the pipeline route as evidenced by plant utilization observed on 11-22-2006. Initial observations indicate areas currently open to cattle grazing harbor the greatest distribution, diversity and density of weeds. Grazing should be controlled in a manner to enhance rather than diminish the plant community. Certain noxious weeds are highly palatable during short stages of the life cycle to certain grazing animals including goats, sheep, mule deer, elk, cattle and horses. Preparation and implementation of an appropriate grazing management plan should be considered. Photo 6. Severe meadow erosion. Mechanical: Photo 7. Typical meadow with burdock. It is recommended senescent, seed -bearing, listed weeds on the route and adjacent to the route be cut, bagged and disposed of in a licensed landfill. Rosettes can be cut with a shovel below the Photo 8. Seed bearing burdock. Photo 9. Seed bearing musk thistle. WeslWater Engineering Chevron Clear Creek 3 Inch Pipeline IVNWMP Page 7 of 14 Photo 10. Houndstongue rosette. Photo 11. Scotch thistle rosette. surface of the soil on plants which are not yet dormant. Even with some seed drop, cutting and bagging will greatly reduce seed release. Future need to do mechanical or other control methods should be reduced after only two seasons of cutting and bagging. Alternative Methods: Some noxious weeds are subject to damage from beneficial insects. Included are Canada thistle stem mining beetle, Ceutorhynchlis !infra, Canada thistle bud weevil, Larinus planus, musk and plumeless thistle rosette weevil, Trichosirocalus horridus, Canada thistle stem gall fly, Urophora cardui, and thistle defoliating beetle, Cassida rubiginosa, which feeds on the foliage of Canada, musk, and plumeless thistles (Sullivan, 2004). Currently, the thistles present are not of sufficient density, in the opinion of WWE, to support populations of insect parasites. Therefore it is unlikely these insects would be helpful unless explosive spread and growth occurs after the pipeline is constructed. The bindweed mite, Aceria malherbae, is a microscopic mite imported from southern Europe as a biological control agent for field bindweed (Hammon, 2006). According to recent anecdotal information it may be a very effective control for bindweed on pipeline route. This mite may be useful for reducing field bindweed. Another alternative method, particularly for cheatgrass infestations and poor to non-existent topsoils in the Utah juniper woodlands on Mt. Blaine, is the application of vesicular-arbuscular mycorrhizal fungi (V/AMF). These fungi, mostly of the genus Glomus are symbiotic with about 80% of all vegetation. Endo-mycorrhizal fungi are associated mostly with grasses and forbs and ecto-nrycorrhizal fungi are associated mostly with trees and some shrubs. In symbiosis, the fungi increase water and nutrient transfer capacity of the host root system by as much as several orders of magnitude (Barrow and McCaslin, 1995). Over-the-counter commercial products, which are better adapted to coating seeds when reseeding and treating roots of live seedling trees and shrubs at time of planting come in powder and are available from many different sources. Some applicators, including a New Castle company, collect and grow local accessions of V/AMF. The latter are applied to weed patches and are WestWatcr Engineering. Chevron Clear Creek 8 Inch Pipeline IVNWMP Page 8 of 14 reputed to greatly increase competition of native plants with Canada thistle in particular thereby affecting a non -chemical control of some noxious weeds. Revegetation Soil types on the property support many of the same species of native vegetation. As stated previously, the recommended mix is limited to grasses due to the prevalence of field bindweed and the need to use selective herbicides to spot treat for perennial Canada thistle and field bindweed, biennial common burdock, bull, scotch, and musk thistle.

Preferred seeding method is multiple seed bin rangeland drill with no soil preparation other than simple grading to slope and waterbars. Seed should be bagged separately so each size group of seed can be metered at the appropriate rate. Applying a quarter pound over an acre with a species such as canby bluegrass is difficult and may require use of wheat bran or rice hulls or some other adjuvant to assist metering the small seeds at the appropriate rate. Alternative seeding methods include but are not limited to: • harrow with just enough soil moisture to create a rough surface, broadcast seed and re - harrow, preferably at a 90 degree angle to the first harrow, • hydro -seeding (most economical in terms of seed cost), and CF<L OrClear Creek 3 Inch Pipeline fVNV"/MP P e 9 1 • hand raking and broadcast followed by re -raking at a 90 degree angle to the first raking. • These are not the only means of replanting the site. However, these methods have been observed to be effective in similar landscapes. Upon successful control of target species and establishment of grasses, shrubs, forbs and trees can be planted without concern for herbicide damage. Few native forb seeds are available commercially as cultivars. Most are collected from natural populations. Native shrubs and forbs often do not establish well from seed, particularly when mixed with grasses. Past experience has shown that stabilizing the soil with grasses, accomplishing weed control and then coming back to plant live; containerized woody species in copses has been the most cost effective method for establishing the woody species component of the plant community.

An applicator has the full range of knowledge, skills, equipment and experience desired when dealing with Canada thistle and other difficult vegetation. A reputable local company, Julius Ag, Andy Julius, Certified Applicator's License No. 11210, Julius Ag, 2169 I-70 West Frontage Road, Debeque, CO 81630, 970-379-6917 has the experience and knowledge necessary for success. Reclamation farming with multiple seed bin range drills and related equipment is also available through Julius Ag. An alternative applicator using V/AMF and other natural products locally is: Alpha Natural, Inc., 1808 Road 245, New Castle, CO 81647, 970-984-2467. Common chemical and trade names may be used in this report. The use of trade names is for clarity by the reader. Inclusion of a trade name does not imply endorsement of that particular brand of herbicide and exclusion does not imply non -approval. Certified commercial applicators will decide which herbicide to use and at what concentration. Landowners using unrestricted products must obey all label warnings, cautions, and application concentrations. The author of this report is not responsible for inappropriate pesticide use by readers.

EPS specific information incorporated as project details are finalized. umbers Revised 9/25/2006 Statement of Policy Facility and personnel safety will always take precedence over maintaining operations. Personnel will not attempt to continue working on or remain at a location if the facility is in an unsafe condition. All personnel are authorized to stop work if an unsafe condition posing an immediate hazard occurs. No reprimands will be given if the situation later proves less serious than thought. Hazards of a less serious nature should be brought to the attention of the supervisor who will assess the situation and initiate appropriate action, Under emergency response conditions, or drills, employees are expected to act only in accordance with their training. At no time wit any employee place themselves, or allow themselves to be placed, into a life-threatening situation. The following priorities will govem our response to any emergency situation: 1. The safety of employees takes precedence over all other considerations. 2. We will minimize impact on the environment once the safety of all personnel has been secured. 3. We will endeavor to minimize damage to or loss of property and equipment, keeping safety and environmental concerns at the top of our priority list. Emergency Action Plan: Scope: This written plan covers the designated actions employees (Chevron & Contractors) associated with the Skinner Ridge Delineation Project (Pieance CreeklDebeque, Colorado) must take to ensure their safety from fire, bomb threats, gas leaks, severe weather, or other emergencies. Elements: Fires or other emergency situations should be verbally reported to the Chevron U.S.A. Inc. person in charge (PIC) in the field location. If they are unavailable call (307) 783-9428, where appropriate 9-1-1 should also be called to initiate public emergency response resources to report the incident. In the event that evacuation is required all employees shall evacuate per posted instructions (if applicable) and report to the following designated muster points Primary Muster Point: Hiner Gate (N39 Deg 32.474 W 108 Deg 19.518 Elevation 5839) Alternate Muster Point: Cowboy Chapel (N39 Deg 29.115 ft. W 108 Deg 19.705 ft Elevation 5506) Field Rally Point: Main Deer Camp approx. 2.1 miles north of Hiner gate on right hand side of road at log cabin. (N39 Deg 34.311 ft, W 108 Deg 20,776 ft Elevation 5985) Note: See attached map. Operator (Person In Charge) is designated to perform a final building check to ensure all temporary/portable office building/s have been evacuated in the event of an emergency. Designated individualls will then remove the sign -in log and report to the muster point. Muster points will be discussed daily prior to job executions and will be carried over into night time operations should they exist. There are no critical operations at the Skinner Ridge Project/ Field that would require personnel to remain behind and operate. However, to minimize the dangers associated with an emergency, any trained employee may shut off the following energy sources after evacuating temporary office facilitiy/s: Building Energy Type Utility Shut-off Location Temporary On -Site Office — Drilling or testis location. Electricity- Generator Propane/Diesel fired devices. Posted at entrance to Drilling rig location. Visitors are required to sign a logbook upon entering any field office or location whether permanent or temporary. They will be required to note the time of their arrival, work location, emergency contact numbers (if not already on file) and departure time from the facility. In the event of an emergency, Chevron personnel wit use the logbook, verbal communication, cell or satellite phones and/or radios at the muster point to account for all personnel. If necessary, available, pre -designated personnel may initiate a search for any missing person as long as it is safe to do so. For Field Work sites, personnel present on location are noted by crew leaders and supervisors. Emergency muster points are pre -established and should be discussed daily before each job during (JSA) job safety analysis. In the event of an emergency, personnel will evacuate to the designated muster point where a headcount will be conducted. Employees who have been certified in First Aid/CPR and have received Bloodborne Pathogen training may render assistance to injured employees. For further information about this plan, contact the Charlie Eagler (HES Champion) at 307- 799-6314 (cell). If he cannot be reached, please contact George Badovinatz (Operations Supervisor) at 307-799-7217 (cell) / 307-783-3613 (office), Dave Howard (Facility Rep.) at 970-986-9823 (cell) / 970-283-1041 (office), or Fairl Dixon (Field Operations) at 970-379-6688 (cell) or 254-387-4949 (satellite). Alarm System: The only current active alarms will be designated "drilling rig " alarms and will be noted on the sign in sheet at rig site - Notification of an emergency situation may be given by using either of the following methods: Temporary Office Facility/s • Verbally • Company Radio • Telephone/ Cell Field Offices and Field Work Sites • Verbally • Company Radio • Telephone/ Cell Evacuation: Employees shall follow the procedures noted below for evacuation in emergency situations: Emergency Bomb Threats Employee Action Evacuate to the Cowboy Chapel parking lot. Fire/Explosion Evacuate to the Cowboy Chapel parking lot. Gas Leak Evacuate to the Cowboy Chapel parking lot if possible or upwind of leak. High Winds, Thunderstorms or Tornadoes Seek immediate shelter in a non -hazardous location. At -Clear Signal: When employees have been evacuated from any building/s or worksite/s, they may only be re-entered after it has been determined to be safe to do so by the designated on-site "Person in Charge". This may be done in consultation with local emergency responders or Chevron Management as appropriate. The Chevron designated onsite "Person In Charge" shall communicate the at -clear signal verbally to all affected employees. Training: Duties of individuals, trained to carry out the safe and orderly emergency evacuation of the Skinner Ridge Delineation Project Temporary office's or worksite/s are noted below: Position Duty AU Employees Evacuate and assist others in leaving building/s or worksitels and reporting to muster point. Designated "Person in Charge" Make final sweep of building's or worksitels to insure that all rooms or sites are evacuated. Take building's sign -in log sheet's to the muster point. Operations Supervisor (or designee) Oversee evacuation, direct additional response as appropriate. Determine when all -clear may be given. Reviews are conducted with employees covered by the plan at intervals noted below. Documentation of each review is contained in the Skinner Ridge temporary office/s located at the current site's of drilling operations. • Upon employee's initial assignment to the Skinner Ridge Project, employees receive training on this plan. • Whenever the employee's responsibilities or designated actions under the plan change. • Whenever the plan is changed. Documentation of each review is contained in the Skinner Ridge Temporary Office's located at the Hiner Gate. Building evacuation drills will be conducted in accordance with local fire codes on an annual basis.

Emergency evacuation route(s), places of refuge, assembly point(s), and the IOCatiOns of key site emergency equipment are identified on this map. Major topographical features and the direction of prevailing windslweather conditions that could affect emergency response planning are also marked on this map. Figure 7-3a is posted at site entry points and at locations throughout the work area. 7.4 Roles and Responsibilities for On -Site and Off -Site Personnel The Project Supervisor is responsible for implementing the emergency response plan and coordinates emergency response activities On this site. Helshe provides speoifie direction for emergency action based upon information available regarding the incident and response capabilities and initiates emergency procedures, including protection of the public and notification of appropriate authorities. In the event of an emergency. Site personnel are evacuated and do not participate in emergency response activities. As a result, this emergency response plan is designed to comply with 29 CFR 1910.38(a). The on- site personnel and their alternates responsible for coordinating site evacuation efforts are listed in Table 7-4. The site relies upon the off-site emergency response organizations listed in the Emergency Contact Information, Table 7-4, to respond to site emergencies. 7.5 Emergency Alerting and Evacuation Site workers are alerted to emergencies through the use of an employee alarm system. The employee alarm systems at this site are listed in Table 7-5. Table 7-5 Employee Alarm Systems Type of Alarm Location How Alain is Used Air horn 350 Three blasts This alarm System is tested periodically under normal site operating conditions to ensure that it is in good working order and can effectively alert all persons on-site. If evacuation notice is given, site workers leave the worksite by way of the nearest exit. Appropriate primary and alternate evacuation routes and assembly areas have been identified. The routes and assembly area will be determined by conditions at the time of the evacuation based on wind direction, the location of the hazard source. and other factors as determined by rehearsals and inputs from emergency response Organizations. Wind direction indicators are located so that workers can determine a safe up wind or cross wind evacuation route and assembly area if not informed by the emergency response coordinator at the time the evacuation alarm sounds. Personnel exiting the site gather at a designated assembly point. To determine that everyone has successfully exited the site. personnel will be accounted for at the assembly site. If any worker cannot be accounted for. notification is given to the Project Supervisor so that appropriate action can be initiated. Contractors and subcontractors on this site have coordinated their emergency response plans to ensure that these plans are compatible and that source(s) of potential emergencies are recognized, alarm systems are clearly understood, and evacuation routes are accessible to all personnel relying upon them. 23 7.6 Emergency Response When the lead person on site determines that outside assistance is required, the applicable off-site organization shown in Table 7-4 is contacted- They provides relevant information to the responding organizations, including hazards associated with the emergency incident, potential containment problems, and missing site personnel. 7.7 Emergency Medical Treatment and First Aid This site does not assign site personnel to provide first aid. Personnel who require medical Care are transferred to a medical facility. Some personnel on site will be trained in basic first aid and will render care to the best of their abilities under the "Good Samaritan" laws. 7.8 Emergency Response Training All persons who enter this worksite. including visitors. receive a site-specific briefing about anticipated emergency situations and the emergency procedures. Prior to the commencement of work and in accordance with the Training Section of this Plan, site personnel are trained in the contents of this emergency response plan, including potential emergencies, personnel roles and responsibibhes, evacuation routes and procedures. and the location of medical assistance. Where this site relies on off-site organizations for emergency response (see Table 7-3), the training of personnel in those off-site organizations has been evaluated and is deemed adequate for response to this site. 7.9 Emergency Response Fire Management We will minimize the risk of accidental fire by utilizing the following mitigation measures as applicable for the site. Strictly adhere to Hot Work Procedures and protocols • Control noxious weeds and cheatgrass Inspect and maintain equipment to minimize potential ignition sources Use spade arrestors on engines where applicable Carry incipient stage fire fighting equipment (up to 20# ABC extinguisher) in vehicles and They (30# ABC extinguishers) will be staged On all pad locations • Individuals will be trained in Incipient stage fire fighting techniques and will respond according to their training to suppress any accidental fires • Will create defensible spaces in line with the Colorado Firewise Guidelines and in line with BLM Fire Management Guidelines Figure 7.3 Primary Muster Point: Hiner Gate (N39 Deg 32.474 W 108 Deg 19.518 Elevation 5839) Alternate Muster Point Cowboy Chapel (N39 Deg 29,115 ft, W 108 Deg 19.705 ft Elevation 5506) Field Rally Point: Main Deer Camp approx. 2.1 miles north of Hiner gate on right hand side of road at log cabin.

Fire Prevention and MCA Business Unit Protection Guidelines Piceancc Basin Safety Plan, Hot Work Permitting Procedures May 2007 SCOPE The scope of these guidelines is to outline some basic principles to avoid the potentials of having an unplanned and out of control fire, while setting some protection mechanisms in place in case it occurs REQUIREMENTS Chevron requirements are set forth to do all in our powers to avoid the potentials of starting an unplanned fire and all individuals will be trained to know what to do and when to do it if the occasion occurs. APPLICABLE DOCUMENTS Safety Plan, Hot Work Permitting Procedures MATERIALS & EQUIPMENT Permits, Fire Extinguishers, Water sources SAFETY Individuals will be trained to allowable response levels, and all care will be taken to avoid a human caused event. Personnel will be given these guidelines to aid them in occasions of nature caused events also. QUALITY These Guidelines will be reviewed periodically and will be shared with employees. During Level III and other audits we will question field workers to insure they have adequate knowledge to protect themselves in an emergency situation. Task 1.0 Fire Prevention Sub Task The field production and processing units will he designed to minimize the potential for starting fires. This includes but isn't limited to; • Flare Stacks • Fired Vessels • Heater Packages • Incinerators 1.2 All work that has potential to cause an ignition source to a combustible material will he covered and planned for using a JSA and Hot Work Permit following the local protocols. • JSA should include weather conditions, and fire potential. BLM Website has this updated daily. • Contact local response personnel and notify them a head of time when doing certain actions that raise the hazards. • Emergency Response Plan will he discussed during JSA meetings • Insure all information is included on the JSA and shared with all personnel affected by the job. CAUTION: Use Hot Work Permit Procedure whenever Hot Work is planned. Important parts of HW Permitting Procedure to comply with for fire prevention • Fire Watch with no other duties when there are any open flames Printed 8/27/2007 9:00:44 AM Page 1 Chevron Production Co. Fire Prevention and MCA Business Unit Protection Guidelines Piceance Basin May 2007 • Fire Watch observes site for 30 minutes after Hot Work ends or when released by Chevron Representative. • A Chevron Rep will be responsible and oversee all Hot Work Activities. • Avoid Field Hot Work whenever possible — minimize potential • Comply with all requirements on the permit and JSA • Monitor site appropriately to the hazards that could be encountered 1.3 Area can be mowed on either side of the road down to a minimal level to help mitigate potential ignition sources from vehicles (as determined by Chevron Representative). This area won't be completely void of vegetation due to storm water damage potentials, but will be kept at a reasonable low leve!. 1.4 Fire Breaks will be mowed into the local landscape to help eliminate fire spread potentials. These areas won't be devoid of vegetation, but will have it kept at minimal levels to avoid fire potentials and addressing storm runoff problems. 1,5 Where applicable we will try to replace the cheat grass, purple mustard, sagebrush, and scrub brush with plants that are less conducive to wildfire spread. 1.6 Vehicle traffic will be restricted to maintained roads only (unless the person has written approval from Chevron Management). This reduces the potential of a fire being started by the catalytic converter. 1.7 Smoking will be restricted to certain locations in our field that are appropriately set up for disposal of the cigarette wastes. No smoking in vehicles or out in the open because of the wildfire potentials. 1.8 Areas around Flare Stacks and Fire vessels will be maintained as bare ground and treated to avoid fire potentials. In some cases other actions will he required to eliminate storm runoff and erosion potentials. 1.9 Work with the BLM and if they see an opportunity to do a prescribed burn to eliminate some fire dangers work with them to make sure it's done safely and with minimal effect on our actions. 2.0 Fire Response 2.1 Chevron Employees will be trained to fight Incipient Stage Fires only. • A fire that can be controlled with in 3 minutes or less with use of a small water hose, shovels, polaski, or fire extinguisher. 2.2 Fire Extinguisher will he strategically located at the well sites, in process areas, or in the personnel's vehicles for response capabilities. 2.3 Actions • Make sure you are in a safe location • Notify others of problem and get help corning • Fight fire if you determine it is in incipient stage Printed 8/Z7/2007 9:00:44 AM Pare Chevron Production Co. Fire Prevention and MCA Business Unit Protection Guidelines Piceance Basin May 2007 3.0 Shelter In Place • Protect others • Proceed to a safe location if you can't control and let others know. 2.4 If the personnel aren't adequately trained or can not handle the situation the plan is to proceed to a safe location and notify others of their location. CAUTION: Do NOT try to outrun a fire if you're in a safe zone. 2.5 Provide a water source for fire fighting responders. This can include but not limited to; • Fresh Water Pond • Dip pits along Clear and Willow Creek • Water Tanks — with no Oil 3.1 If the fire is larger than you can safely respond go to a safe location and wait for assistance. Designated Safe Zones • Well pads away from tanks, pits (unless water — no oil), and heater packages. • Irrigated Fields • Process areas away from Hydrocarbon vessels • Roads as a last resort if you can't make it to a larger open area 3.2 Areas to avoid • Cheat grass, purple mustard, dead/dry foliage areas — fast burning fire area • In creek bed close to trees or shrubs — chance of things (trees) falling on you and superheated air flows. • Close to any plastic lines, gas/oil storage, or high pressure lines/equipment • Talus slopes — heat and vapors go up slopes and are death traps • Trailers or wood structures Printed 8/27/2007 9:00:44 AM Page 3 I '?:7;111.)11.►9:j)r Complete Production Services P.O.

No. 1105-06 Class III Cultural Resource Inventory Report for Two Proposed Pipeline Route Segments (8.50 miles) in the Clear Creek and Deer Park Areas of Garfield County, Colorado, for ChevronTexaco GRI Project No. 2533 3 June 2005 Prepared by Carl B. Conner and Barbara J. Davenport Grand River Institute P.O. Box 3543 Grand Junction, Colorado 81502 BLM Antiquities Permit No. C-52775 Submitted to Bureau of Land Management Grand Junction Field Office 2815 I -I Road Grand Junction, Colorado 81506 Abstract Grand River Institute (GRI) conducted a CIass III cultural resources inventory of two proposed pipeline route segments in the Clear Creek and Deer Park areas of Garfield County, Colorado, for ChevronTexaco. These routes totals approximately 8.50 miles long, of which 6.85 miles are located 011 private lands and 1.65 miles are on Bureau of Land Management (BLM) administered property. A 200 -foot wide corridor was inspected for the pipeline routes, resulting in a survey ofa total of 166 acres of private property and 40 acres of BLM land. The survey and report preparation were conducted by Carl B. Conner, Barbara J. Davenport, Nicole Darnell, Jim Conner and Dana Archuleta. A files search was completed on 19 May 2005, and the field inventory was carried out on May 3 P` and June t of 2005. The inventory was undertaken to ensure the project's compliance with federal legislation governing the identification and protection of cultural resources. The purposes of this investigation were to identify resources within the project area likely to be affected by the proposed action, to evaluate these sites' eligibility for listing in the National Register of Historic Places (NRI -IP), and to make management recommendations for those sites found to be eligible or potentially eligible. The files search identified three historic sites within the project corridors. Two sites (5GF424 and 5GF5425) are structures near the mouth of Clear Creek and one site is reportedly an historic race track (5GF351), all occurring on private property. The Roan Creek Community Center (5GF424), was revisited just last year for another project so a new reevaluation form was not completed for this site. The Roan Creek School House (5GF425) was previously field evaluated as eligible for listing on the NRIIP. Site 5GF425 was reevaluated as "field not eligible" for listing on the NRNP. Site 5GF351, the historic race track, was previously field evaluated as need data. With this revisit, no indication oldie race track was found. Site 5GF351 was reevaluated as "field not eligible" for listing on the NRNP. In conclusion, the two historic structures will not be affected by the proposed pipeline construction. The historic race track site has been previously disturbed by road construction, and farming/ranching activities and there is no subsurface potential. Since the pipeline construction through this site will take place in already disturbed areas (road corridor) archaeology clearance for the project is recommended. ii Table of Contents Introduction 1 Location of the Project Arca Environment 1 Summary of Files Search and Literature Overview 2 Study Objectives 4 Field Methods 4 Results 4 Site Significance 5 Site Description 5 Discussion 7 Sumntaly of Site Evaluations and Recortnendations 8 References 9 Appendix A: Tables of Previously Recorded Cultural Resources and Bibliographic List of Previously Conducted Inventories A.1 Appendix B: OAHP Site Form B.1 List of Figures Figure 1.

These segments total approximately 8.5 miles long, of which 6.85 miles are located on private lands and 1.65 miles are on Bureau of Land Management administered property. A total of 166 acres of private property and 40 acres of BLM land was surveyed. The survey and report preparation were conducted by Carl E. Conner (Principal Investigator), Barbara J. Davenport, Nicole Darnell, Jim Conner and Dana Archuleta. A files search was completed on 19 May 2005, and the field inventory was carried out on May 31' and June i 5' of 2005. The survey was done to meet requirements of the Federal Land Policy and Management Act of 1976, the National Ilistoric Preservation Act (as amended in 1992), the National Environmental Policy Act (NEPA) of 1969, and Article 80.1 of the Colorado Revised Statutes. These laws are concerned with the identification, evaluation, and protection of fragile, non-renewable evidences of human activity, occupation and endeavor reflected in districts, sites, structures, artifacts, objects, ruins, works of art, architecture, and natural features that were of importance in human events. Such resources tend to be localized and highly sensitive to disturbance. Location of the Project Arca The project area is located about 12 miles north of the town of De Beque in the Clear Creek and Deer Park areas of Garfield County, Colorado. In general, the pipeline will follow the west side of County Road 211 and the north side of the upgraded Deer Park Road, but the 200 foot wide inventory corridor includes both sides of these roads. The three segments of pipeline occur within T. 5 S., R. 98 W., Section 36; and 1'. 6 S., R. 98 W., Sections 4, 9, 10, 11, 15, 22, 27, 33, and 34; 6th P.M. (Figures 1 and 2). Environment The proposed project is within the Piceance Creek Basin, one of the major geologic subdivisions of Colorado. The Piccance Creek Basin is an elongate structural downwarp of the Colorado Plateau province that apparently began its subsidence approximately 70 million years ago during the Laramide Orogeny. Sediments from surrounding highlands were deposited in the basin, accumulating to a thickness of as much as 9000 feet by the lower Eocene epoch, when subsidence ceased. Regional uplift occurred in the Late Tertiary, and erosion of tile -area has continued since -(Young arid -Young 1977:43:46):The Wasatch formation underlies the south portion of the study area, while the Green River Formation 1 occurs in the northern part. The project area rests within valley bottoms of the Roan Plateau. Elevations range from about 5500 to 6000 feet. These elevations have three vegetation communities including saltdesert sluvblands, pinyon juniper woodlands, and sagebrush/grasslands. Ground visibility ranged from 30% in the sagebrush and greasewood to about 90% in the disturbed areas along the roads. These communities support a variety of wildlife species although the present day land use of the project area (including energy development, grazing, ranching and farming) has pushed most large mammals into the surrounding mountains. There, mule deer, elk, coyote, and black bear are common, as are cottontail rabbits, beavers, and various rodents. Mountain lion, bobcat, fox, skunk, badger, and weasel are also likely inhabitants. Bird species observed in the area include the jay, raven, red -shafted flicker, long-eared owl, and various raptors. There is little climate variation within the study area. These relatively low elevations are host to a cool semiarid climate where temperatures can drop to -10 degrees F during the winters and summer temperatures may reach 100 degrees F; there is a maximum of 120 frost free days and the annual precipitation is about 14 inches. The surrounding higher elevations are characterized as cooler and moister. Annually, the high mountain temperatures could average 5 degrees cooler and the precipitation as much as 14 inches greater that the surrounding low elevations (USDA SCS 1978:244). Suutnniary of Files Search and Literature Overview A records search was made for the project area through the BLM on 19 May 2005. An on-line search of the records at Colorado Historical Society's "Compass" site was also completed. These searches, which also included GLO Plats, were conducted to determine which areas were previously surveyed, to identify all known cultural resources in the vicinity of the study area, and to gather pertinent published and unpublished information on previous surveys in the immediate arca. This information is important in the interpretation and evaluation of the cultural resources that were expected to be found. The files search identified tluee historic sites within the project corridors. Two sites (5GF424 and 5GF5425) are structures near the mouth of Clear Creek and one site is reportedly an historic race track (5GF351), all occurring on private property. In addition, there are nine sites in the general vicinity of the project area and these are listed in Table A-1 in Appendix A. Table A-2 (Appendix A) provides a bibliographic list of the previous projects conducted near the project area. Cultural resource investigations in the region have yielded surface diagnostic 2 artifacts and excavated cultural materials consistent with the regional cultural history. Evidence of the Paleoindian Era, the Archaic Era, Formative Era, and Protohistoric Era has been found in the area. Historic records suggest occupation or use by EuroAmerican trappers, settlers, miners, and ranchers as well. Overviews of the prehistory and history of the region are provided in documents published by the Colorado Council of Professional Archaeologists' entitled Colorado Prehistory: A Context for the Northern Colorado Plateau (Reed and Metcalf 1999), and by the Colorado I-Iistorical Society entitled Colorado Plateau Country Historic Context (husband 1984). A more specific document regarding the Euro -American settlement of the study area is History of Roan Creek and De Beque (Prather and de Beque, n.d.). As therein described, in the De Beque - Roan Creek area, the first to file homestead claims were Robert Eaton, L.T. Stewart and George Gibson along Dry Fork. Brothers Harve and John Van Cleave filed claim to Roan Creek property and established a cattle business in 1883 that became well known in Western Colorado. Other creeks in the area are named for the early ranchers who often brought cattle and cowboys with them. Kimball Creek is named for Gayton and William Kimball. Con [now Conn} Creek is named for C.H. Conwell. Tom Wallace set up his outfit on Wallace Creek, and John Carr on Carr Creek. George and Frank Newton settled on Clear Creek --apparently named before they arrived. The importance of water --and water rights --to the settlers not only was acknowledged by naming the creeks after thein but also by so naming the ditches. Accordingly, one will also find the familiar names of Charles Creek, Joe Newman, A.S. Hirnebaugh, Henderson Frashier, Tom King, George P. Anderson, George Hayes, and W.A. DeLaMatyr on ditches and ranches of the surrounding area. By 1888, at least 31 ranches were in active operation, and a total of 140 cubic feet of water had been filed on (ibid.:3-4). The town of De Beque is named for Dr. W.A.E. de Beque, who arrived with three companions (Fred Webster, John Boudin and Dick Smith) in the spring of 1884. He established a ranch on the banks of the Grand River near its confluence with Roan Creek. The first post office was within a log building built by Dr. de Beque, which served as his office, a drug store and a general store. Marie de Beque was the first Postmistress, officially named so in 1888. During this year, the town site of De Beque was established outside the boundary of the de Beque's ranch on what was originally the H.L. Spencer homestead. It was platted by surveyor John Walzl and given the name of De Beque in February of 1888. Shortly thereafter, Dr. de Beque built the first residence in the town (ibid.:3-4). Adjacent to Ravensbeque (Dr. de Beque's ranch), the first school was started in 1886 by Mrs. Joseph McMillen, who initially began teaching her own children, but soon took in others from the surrounding homesteads. About that same time, a public school was opened on Con [Conn] Creek. Later, county schools were opened on Brush Creek, Kimball Creek, Dry Fork and main Roan Creek. The school started by Mrs. McMillen was moved to town where various buildings served as classrooms untila stone school house was built itt 1892. Grades through high school were added as were new buildings to the school grounds, and in 3 1912, the first class was graduated from the high school (Prather and de Beque, n.d.:6). The town grew steadily during the late 1800's and early 1900's, due in part to the coming of the railroad in May of 1890. It quickly became an areal center serving not only the Roan Creek ranches north of the Grand River, but also the Blue Stone Valley farms and ranches south of the river --after a bridge was built in 1891. Over the years, many people came and left, but the town's population rarely exceeded 400 persons (ibid.:7-9). Study Objectives The purpose of the inventory was to identify and record all cultural resources within the areas of potential impact, to assess their significance and eligibility to the National Register of Historic Places (NRNP), and to make management recommendations for those sites found to be eligible or potentially eligible. Based on the files searches cultural resources were expected to be encountered. Field Methods A Class III cultural resource inventory of the project areas was performed by two persons who walked zig zag transects along the two segments of the proposed pipeline route to cover a 60 meter (200 foot) wide corridor centered on the west side of the existing Clear Creek road and the north side of the Deer Park road. Crew members worked from USGS 7.5' series maps. Cultural resources were sought as surface exposures and were characterized as sites or isolated finds. Sites were defined by the presence of five or more artifacts and/or significant feature(s) indicative of patterned human activity. Isolated finds were defined by the presence of a single artifact or several artifacts, which apparently represent a single event (e.g., a single core reduction), and is surficial in nature. All cultural resources such as open camps, lithic scatters, and isolated finds were recorded as they were encountered. Sites were to be recorded using the following methods of mapping and note taking. The basic approach to the data collection was to be the continuous mapping of observed artifacts and features by recording UTM coordinates (NAD 83 Datum) using a Trimble Geo XT. Site maps were to be created using corrected GPS data and ARCMAP. Photographs were to be taken at each site and include general views and specific artifacts or features. Field notes and photo negatives for this project are on file at Grand River Institute, while the photographs are submitted to the BLM. No artifacts were collected. 4 Results As expected, cultural resources were encountered during the survey. Field conditions were as anticipated, and did not affect the methods. This portion of the report presents a discussion of site significance evaluation and describes the two previously re-recorded historic sites, Site Significance The National Historic Preservation Act of 1966 (NIIPA) directs the BLM to ensure that BLM-initiated or authorized actions do not inadvertently disturb or destroy significant cultural resource values. Significance is a quality of cultural resource properties that qualifies them for inclusion in the NRI -IP. The statements of significance included in this report are field assessments to support recommendations to the BLM and State Historic Preservation Officer (SHPO). The final determination of site significance is made by the BLM in consultation with the SHPO and the Keeper of the Register, The Code of Federal Regulations was used as a guide for the in -field site evaluations. Titles 36 CFR 60, 36 CFR 800, and 36 CFR 64 are concerned with the concepts of significance and (possible) historic value of cultural resources. Titles 36 CFR 65 and 36 CFR 66 provide standards for the conduct of scientific data recovery activities. Finally, Title 36 CFR 60.4 establishes the measure of significance that is critical to the determination of a site's NRI -IP eligibility, which is used to assess a site's research potential: The quality of significance in American history, architecture, archaeology, and culture is present in districts, sites, buildings, structures, and objects of State and local importance that possess integrity of location, design, setting, materials, workmanship, feeling, and association, and a) that are associated with events that have made a significant contribution to the broad patterns of history; or b) that arc associated with the lives of persons significant in our past; or c) that embody the distinctive characteristics of a type, period, or method of construction, or that represent the work of a master, or that possess high artistic values, or that represent a significant and distinguishable entity whose components may lack individual distinction; or d) that have yielded, or may be likely to yield, information important in the prehistory or history. Site Description The Roan Creek Community Club (5GF424) was revisited just last year for another project so a new reevaluation form was not completed for this site. The Roan Creek School (5GF425), was revisited and reevaluated along with site 5GF351, an historic race track. This section provides general descriptions of these sites. Location data for them is provided in Appendix A (Figure A-1). Detailed information for 5GF425 is provided in Appendix B: 5 OAUP Site Form (available at the I3LM and OAHP). Site 5GF351 was originally recorded only as a report from a local (unnamed) land owner in 1978 by the Museum of Western Colorado. The original site form contained very little information and an assessment of the reported location was never conducted. Upon revisiting the site, no indication of cultural manifestations remained. It could not be relocated by this inventory and there is no subsurface potential. Mucli of the site area has been previously disturbed by road construction and farming/ranching activities. Evaluation and Management Recommendation Due to a perceived lack of potential for this site to yield additional significant information regarding the area's history, this site is field evaluated as not eligible for listing on the National Register of Historic Places. No further work is necessary. Site 5GF424 is the Roan Creek Community Club building complex and is presently in use as the "Cowboy Chapel of Prayer." The site was previously recorded, however, that form was not signed or dated and contains limited information. The site is located at the confluence of Clear Creek (County Road 211) and Roan Creek (County Road 204) at an elevation of 5520 feet. Vegetation on the site is grass and the surrounding open areas contain sagebrush. Most of the ground around the structures is barren and includes a dirt parking area. The main focus of the site is a large milled log structure which measures 54 feet in length by 30 feet in width and rests on a concrete foundation. The south side (front) of the building has double door entryway which measures 7 feet by 15 feet and contains two, five - horizontal panel, plywood doors. The gable ends and the upper portion of the entryway have cedar shingle siding in a coursed pattern. The cast wall has three windows and one (newer) door opening and the west wall has four windows and a door while the rear wall and entryway each have two double windows of an older style of true divided lite glass with a pattern of 2W3H. The asphalt shingle roof appears to be new (the original site form states that the roof was of corrugated metal). Two brick chimneys are present, one in the center of the west wall and the other at the northeast corner of the building. Also, the concrete landing, stairs and iron hand rails at the entryway seem to have been replaced fairly recently. Approximately ten feet from the northwest corner of the main log structure is a storage shed which measures 12 feet by 8 feet and is constructed of milled lumber with a metal shed style roof. This building has a single do&r on its east side and a single small window on the south wall. Forty feet north-northeast from the northeast corner of the main 6 log building is an old privy with a wood shed style roof. The site has been well maintained and is currently in use. This structure is referenced in a booklet entitled, "Cattle and Shale, 1884-1984, A Story of Roan Creek and De Bcclue" in the section that discusses families and ranching on upper Roan Creek. The description from pages 13 and 14 is as follows: "A community hall, "I-Iighmore Hall" was erected, which became the center of many social gatherings and dances. Plays, musicals, all day picnics, church services, and neighborhood gatherings of all kinds were held there. The guiding star and musical director of all this activity was Pearl Sullivan, the wife of Dougald Sullivan, whose ranch was the I-limcbaugh ranch at the mouth of Clear Creek. Pearl and her music will long be remembered. There were other Sullivan brothers, too, who engaged in the cattle business here for years, but they are not here now. Other names closely associated with the development of the community are Flasche, Franklin, Firvin, Letson, Huntley, Gordon, and Simmons, but most of the people who bore those names and lived among us for awhile, are gone." Evaluation and Management Recommendation This site appears to meet criteria for National Register status (36 CFR 60.4 a, b and c) and is field evaluated as eligible for listing on the National Register of Historic Places. It will not be directly affected by the proposed project and no further work is recommended. Site 5GF425 is the old Roan Creek School building. It is presently not in use. The site was previously recorded, however, the forth was not signed or dated and contains limited information. The site is located along County Road 211 near the confluence of Roan and Clear Creeks in Garfield County at an elevation of 5530 feet. Surrounding vegetation is grass and sagebrush. The site consists of a one room school house with and an attached entryway/ mudroom. It is a framed structure with horizontal wood -siding. It was painted white sometime in the past, however, portions are beginning to weather or arc lacking paint altogether. The main room has a front gabled roof of galvanized corrugated metal while the entry has a shed (half -gabled) roof of milled lumber with wood shake shingles (most of which are missing). The main room measures 22 feet by 14 feet and has five single hung windows (2 sashes each) on the east wall and one single hung window (2 sashes) on the west wall, all measuring approximately 24" by 60" overall. All these windows are authentic divided lite with a 2W 1 I-1 pattern to each sash, however the glass is no longer present. No window or door openings are on the south wall. This room has a brick chimney along the center of the west wall and extends on the exterior approximately five feet up from the roof (on its lowest side). The interior of this room possesses remnant areas of wall paper with a childlike motif 7 (baby ducks, chicks, birds etc.) and some modern graffiti. Some old shelves were also present. There is electrical wiring on the exterior of the east and south walls. The entry/nmulroom on the north end measures 10 feet by 14 feet and has a single door on the north wall and a square window opening (about 30 inches) on each the east and west walls. Again, the glass is no Longer present, A search for any reference to this school was made in a booklet entitled, `Cattle and Shale, 1884-1984, A Story of Roan Creek and De Tacque," but none was found. Despite this, the estimated time of construction is ca. 1930. Evaluation and Management Recommendation This site does not appear to meet criteria for National Register status (36 CFR 60.4 a, b and c). The structure seems to be structurally unsound as it is listing to the east. Given its deteriorating condition and lack of historic artifacts or references, and due to a perceived lack of potential for this site to yield additional significant information regarding the area's history, it is field evaluated as not eligible for listing on the National Register of Historic Places. No further work is necessary. Discussion This project has provided an opportunity to continue the investigations into the Clear Creek and Deer Park Valleys. As expected, historic structures were the site type encountered by the inventory. One such site was re-recorded. Other farm and ranch complexes are present near the pipeline route that are likely to date to the first half of the twentieth century. Limitations to the study included the disturbance of much of the proposed routes by previous construction activities (road, ditch, fence, etc.) or by cultivation. Summary of Site Evaluations and Recommendations The eligibility determination and consultation process is guided by Section 106 of the NHPA (36 CFR 60, 63, and 800). Inventory to identify, evaluate, and mitigate potential effects to cultural resources affected by an undertaking is the first step in the Section 106 process. BLM actions cannot be authorized until the Section 106 process is completed (36 CFR 800.3). Final determinations of National Register eligibility and effect are sought from the controlling federal agencies in consultation with the State Historic Preservation Officer (SHPO) and the Advisory Council on Historic Preservation. The files search identified three historic sites within the project corridors. Two sites (5GF424 and 5GF5425) are structures near the mouth of Clear Creek and one site is reportedly an historic race track(5GF351), all occurring on private property. The Roan Creek Community Center (50F424), was revisited just last year for another project so a new reevaluation form was not completed for this site. The Roan Creek School House (5GF425) 8 was previously field evaluated as eligible for listing on the NRI -IP. Site 50F425 was reevaluated as "field not eligible" for listing on the NRI -IP. Site 5GF351, the historic race track, was previously field evaluated as need data. With this revisit, no indication of the race track was found. Site 50F351 was reevaluated as "field not eligible" for listing on the NRHP. In conclusion, the two historic structures will not be affected by the proposed pipeline construction. The historic race track site has been previously disturbed by road construction, and farrningfranching activities and there is no subsurface potential. Since the pipeline construction through this site will take place in already disturbed areas (road corridor) archaeology clearance for the project is recommended. As directed by the new 36 CFR800 regulations, this inventory included the search for relevant traditional cultural properties. None were found. 9 References Husband, Michael B. 1984 Colorado Plateau Country Historic Context. Colorado I-Iistorical Society, Denver. Prather, Sarah and Armand de Beque. n.d.

The proposed 8 -inch pipeline, which is approximately 6.25 miles long, runs parallel to Garfield County Road 211, except on the southern portion where it turns west and nins for about 2 miles (Figure 1). Surveys were conducted using roadside observations from a motor vehicle and on foot in order to more thoroughly inventory the pipeline alignment. Field observations to document the presence of raptors were conducted using binoculars, listening for raptor vocalizations and searching for nests and sign of raptor presence. Searching for raptor sign included looking for droppings, castings, feathers, excrement (whitewash) and discarded prey items, particularly around nest sites. Potential raptor nesting habitat was surveyed including pinon-juniper woodlands and box-elder/Mexican locust vegetation that was predominantly found along the Clear Creek riparian corridor. The canyon walls along Clear Creek and its tributaries were surveyed to determine the presence of raptors and nest sites. Plant surveys were conducted in conjunction with raptor and bird of conservation concern inventories. RESULTS Raptors Two species of raptors were observed during the survey. Species included Cooper's Hawk (Accipiter cooperii) and American Kestrel (Falco sparverius)`, seven individual raptors (5 adults, 2 chicks) were counted. Two active nest sites were found and four nests that were likely to have active during the 2006 nesting season were located (Table 1 and Figure 2). The survey was conducted late enough in the current nesting season that a Targe portion of raptors have already fledged their chicks. The inactive nests (at time of survey) were determined to have been either active and fledged or possibly active but failed, based on observations in and around the nest. In most cases, raptor whitewash was observed under nests or deposited on current annual plant growth, which indicates recent presence of raptors. One possible American Kestrel nesting territory was located, but no nest was found. Based on chick size, feathered development and movements within Cooper's Hawk nest # 2, the young were estimated to be approximately 10-12 days old on July 6, 2006 (Figure 3 and 4). Cooper's Hawks will typically fledge at about 30-34 days. Therefore, it is likely that fledging would occur around July 30. The status of nest # 1 is unknown (either eggs or chicks) and if the adults were incubating at the time of the survey, fledging may not occur to sometime in mid- August. The active Cooper's Hawk nest sites #'s 1 and 2 are located about 105 feet and 265 feet from the centerline of the pipeline ROW, respectively (Figure 1 and 2). The proposed pipeline construction will result in increased human activity and vehicular traffic in the vicinity of the nest site, increasing the potential of nest failure. What is not known is the level of vehicular/human activity that would cause these nesting pairs to abandon the nests. The Colorado Division of Wildlife does not have a recommended buffer for Cooper's Hawks; however, it is our opinion that a one-quarter mile buffer zone around this nest would decrease the likelihood of nest failure due to project related disturbance. Nests # 2 is located in a box -elder tree about 300-400 feet east of an active drill pad west of Clear Creek. This pad has apparently received a substantial amount of activity and daily traffic and these birds have shown a tolerance for this level of disturbance. In general, raptors have a higher tolerance to occasional vehicular traffic and a lower tolerance to "constant" human -related activity on the ground. It is generally accepted by avian biologists that raptors have a stronger fidelity to their nest site after young have hatched and are more apt to abandon their nest site in response to disturbance during incubation.

Cooper's Hawk 12S 730847 4376427 Cooper's Hawk territory/roosting site in a box -elder along Clear Creek. No nest found, but whitewash and feathers on ground indicated frequent use in the area. 2 Construction Recommendations: If possible, delaying pipeline construction within 0.25 miles of the active nest sites until fledging occurs will reduce the chances of nest failure. The nest sites should continue to be monitored by qualified personnel if construction approaches the nest site prior to fledging. If construction cannot be delayed until fledging, construction activities, vehicular and equipment traffic, and on -ground personnel should be confined to the side of the pipeline corridor away from the nest, which would maximize the buffer between disturbance and the nest. Individual raptors react to disturbance inconsistently; therefore, it is difficult to predict how these birds, which have adapted to the current level of disturbance, would react to pipeline construction. Birds of Conservation Concern The U.S. Fish and Wildlife Service places its highest priority for conservation for those species listed as Birds of Conservation Concern for the Southern Rockies and Colorado Plateau. No birds of conservation concern were observed during the survey. Clear Creek, due to the riparian vegetation, is suitable habitat for a variety of bird species. Threaten, Endangered, or Sensitive Plant Species Plant species that may be subject to protection under the ESA list and could potentially occur in this area are shown in following table. Common Name Scientific Name ESA Status Uinta Basin hookless cactus Sclerocactus glaucus Threatened (T) Debeque phacelia Phacelia submutica Candidate for Listing Debeque milkvetch Astragalas debequaeus Proposed for Listing For two of these species, specific soil types are necessary for the occurrence of these species. The Debeque phacelia and the Debeque milkvetch require soils consistent with the Wasatch formation and this soil type was not observed along the pipeline alignment. The soil type along Clear Creek appears to be that of the Green River formation. The sagebrush and open pinon juniper along Clear Creek and on the westward portion of the pipeline bisects possible Uinta Basin cactus habitat but no plants were observed.

Blaine marks the south end of Skinner Ridge on the west side of Clear Creek Prepared for: Chevron/Texaco USA Prepared by: WestWater Engineering 2570 Foresight Circle #1 Grand Junction, CO 81501 In Coordination with: Cordilleran Compliance Services, Inc. May 2007 Clear Creek Biological Survey May 2007 1.0 Introduction Chevron requested that WestWater Engineering (WWE) conduct a biological survey as early as possible in Spring 2007 to document the location of raptor nests, the presence of Threatened, Endangered and Sensitive Plant Species (TESS); the extent of weed infestations; the presence and location of Birds of Conservation Concern (BOCC) other than raptors; the location of waterways under the jurisdiction of the U. S. Army Corps of Engineers (COE); and the general condition of the aquatic habitat in Clear Creek and its tributaries. 1.1 Project Scope and Location Clear Creek is located in Garfield County, Colorado. It is one of the major tributaries of Roan Creek. The mouth of the canyon is located approximately 12 miles north of the town of DeBeque. Clear Creek and its tributaries drain approximately 113 square miles of the Roan Plateau. Elevations range from 5,485 ft at the mouth of the canyon to 8,011 ft at the top of Mount Blaine (see Photo 1). This biological survey was restricted to the portion of Chevron properties located under the rim of Clear Creek (see Photo 2 and Figure 1). This area is referred to as the Clear Creek drainage or "the canyon" in the following sections of the report. Although Chevron is actively developing the natural gas resources in Deer Park Gulch, that drainage is owned by Shell and WWE biologists did not receive permission to survey the Shell private surface. The same restriction applied to Doe Gulch, Scott Gulch and approximately 1 % miles of lower Clear Creek. Photo 2. This biological survey was limited to Chevron property under the rim of Clear Creek WestWater Engineering Page 1 of 24 pages 5/21/2007 Figure 1: Chevron Clear Creek Overall Map Biological Survey Westwater Engineering Miles (Scale: 1:100,000) 0 0.5 1 2 1.2 Landscape Setting During the survey, Clear Creek was flowing the entire length of the stream due to spring run-off. As runoff ceases, flows diminish and the stream flows intermittently, disappearing underground at several locations. The vegetation adjacent to the stream consists of a few riparian deciduous shrubs and a woodland over story comprised of mountain boxelder (Acer negundo), introduced and naturalized New Mexico locust (Robinia neomexicana), a few remnant of Fremont cottonwoods (Populus firemontii) in lower Clear Creek, and narrowleaf cottonwoods (Populus angustifolia) above the confluence of Cottonwood Creek. In some areas the New Mexico locust has crowded out most native shrubs normally found in this riparian zone such as skunkbush sumac (Rhus trilobata), wild rose (Rosa woodsii), chokecherry (Prunus virginiana), and willow (Salix spp.) Woody vegetation on the upland slopes consists of basin big sagebrush (Artemesia tridentata tridentate), gambels oak (Quercus gambel), rabbitbrush (Chrysothammnus spp.), snowberry (Symphoricarpus occidentalis), serviceberry (Amelanchier alnifolia), skunkbush sumac, currant (Ribes spp.), Oregon grape (Berberis repens), and clematis (Clematis spp.). The understory is primarily cheatgrass (Bromus tectorum) and a mix of annual, biennial and perennial weeds. Few native grasses and forbs are present. Potential natural vegetation for meadows includes basin big sagebrush, western wheatgrass (Pascopyrum smithii), and basin wildrye (Leymus cinereus). For moderate, loamy slopes, needle and thread (Hesperostipa comata comata), bluebunch wheatgrass (Pseudoroegneria spicatum spicatum), Indian ricegrass (Achnatherum hymenoides), western wheatgrass, Wyoming big sagebrush (A. t. wyomingensis), and winterfat, (Krascheninnikovia lanata) is expected. Similar vegetation on the steeper but still moderate, brushy slopes is expected with the addition of bottlebrush squirreltail (Sitanion hystrix) and shadscale saltbush (Atriplex confertifolia). 2.0 Birds of Conservation Concern 2.1 Background Information As part of the protection and management of avian species, the Fish and Wildlife Service (FWS) in 2002 published a list of BOCC (FWS 2002). In a Memorandum of Understanding (MOU), the Bureau of Land Management (BLM), FWS and Forest Service (FS) placed the highest priority for conservation on birds included on the BOCC list. A subset of this list includes a register of BOCC for the Southern Rockies and the Colorado Plateau, including Western Colorado. Not all of these BOCC species occur regularly in Colorado and some are present only as seasonal migrants. After a thorough review of the literature (Andrews and Righter 1992, Kingery 1998), WWE biologists compiled a list of the BOCC species likely to nest in the Clear Creek/Roan Plateau area. Habitat and nesting records for BOCC, as described in the Colorado Breeding Bird Atlas (Kingery 1998, and references therein) and Colorado Birds (Andrews and Righter 1992), in the vicinity of Clear Creek are summarized below. Bird identification and taxonomic nomenclature are in accordance with that applied by the Colorado Breeding Bird Atlas Project (Kingery 1998). 2.2 Raptors The BLM, in its approved White River Resource Area Resource Management Plan (1997), places special emphasis on conservation of all raptors, including species indigenous to the Roan Plateau but not on the BOCC list. The BLM objectives for raptors state: "Maintain the short- term utility and promote the continued long-term development and availability of suitable raptor WestWater Engineering Page 3 of 24 pages 5/21/2007 habitats. This includes prey base, nest sites and other special habitat features necessary to help stabilize or allow increases in regional raptor populations." Table 1 includes the common name, scientific name, BOCC status, habitat requirements and breeding status for raptors that could be observed in the Clear Creek drainage. Table 1.

The search was focused to locate active raptor nests; however, all raptor sightings and nest locations (including inactive nests) were recorded. Based on a reconnaissance of the entire drainage on March 29, the area was divided into 33 "search areas" to facilitate surveys of the extensive cliff habitat. Biologists worked in two-man teams and spent an average of four hours per session systematically searching the cliff faces for nests and bird activity following protocol described by Craig and Enderson (2004). Each biologist used binoculars and a spotting scope equipped with a zoom ocular lens (usually 20-60 power variable) which permitted close -in views of potential nest sites. When possible, two to three teams worked together covering up to two miles of the canyon to better track eagles, falcons and buteos and determine what ledges or caves were being actively used by the birds. Cliff searches were most productive in the morning hours; in the afternoons, WWE biologists walked the riparian corridors or pinon-juniper (PJ) -covered hillsides searching for nests of other raptor species. In addition to these visual searching techniques, the biologists used the recorded call play -back methodology described by P. Kennedy (Kennedy and Stahlecker 1993; the "Kennedy- Stahlecker-Rinker" method) as modified by R. Reynolds and others (1992) for the southwestern United States. WWE biologists used "Predation MP3 Game Caller" units and played the call of a Great Horned Owl or a Cooper's Hawk alarm call in an attempt to locate raptors who often respond to the presence and calls of other raptors. In an attempt to determine which owl species are present in Clear Creek canyon, an owl survey was conducted during the evenings of April 25 and 26, 2007. Two teams started at opposite ends of the canyon, one at the mouth and the other at the confluence of Willow Creek and No Name Creek. Using the "Predation MP3 Game Caller" units, the owl calls were played for 30 seconds and biologists listened for response for 2 minutes for each species of owl; each team played the calls of two owl species before driving one half mile along the main road to the next station. The team moving down -canyon played the Northern Pygmy Owl and Long-eared Owl calls, while the team traveling up -canyon played the Flamm elated Owl and Northern Saw -whet Owl calls. A total of ten minutes were required to play calls, listen for response, and move to the next station. Each team played their owl calls at 32 stations, covering the main canyon and Tom Canyon. All locations of birds, nests and owl response were recorded using handheld GPS units and locations are reported as UTM coordinates (Datum: WGS84, Zone: 12S). WestWater Engineering Page 6 of 24 pages 5/21/2007 2.4 Raptor Observations WWE biologists observed an abundance of raptors in Clear Creek in April, 2007. Numerous individuals of ten species were recorded and biologists determined that eight species were nesting in the canyon. Golden Eagles were well established in Clear Creek in late March and were observed the entire length of the canyon. Eagle cliff nesting sites were located from the face of Mt. Blaine to the upper end of Willow Creek. Red-tailed Hawks were observed on numerous occasions throughout the entire drainage. Northern Harriers were observed from late March, primarily hunting along the canyon floor, but no nesting sites were recorded. Sharp -shinned Hawks were observed on several occasions, but no nesting sites were discovered. American Kestrels were observed all month throughout the drainage. Peregrine Falcons appeared about mid-April and established nesting territories in Tom Canyon and upper Clear Creek. Likewise, Cooper's Hawks appeared about mid-April, and through the rest of the month these birds were establishing nesting territories. Like Red-tailed Hawks and Golden Eagles, Cooper's Hawks were found throughout the entire drainage. WWE biologists also expected to find Prairie Falcons, but none were observed in Clear Creek. Great -homed Owls were observed both in the PJ habitat under Mt. Blaine and in the riparian habitat (night surveys) along the creek(s). Flammulated and Northern Saw -whet Owls response locations were recorded during night owl surveys in the riparian habitats. Photos 3 and 4 portray a Northern Saw -whet Owl and a Flammulated Owl that responded to calls during the owl survey. Photos 3 and 4. Northern Saw -whet Owls (L) and Flammulated Owls (R) responded to the calls Figure 2 shows the locations of active and inactive raptor nests as well as the locations of owl responses during the owl survey. Details are provided below for each active raptor nest that was discovered; the following abbreviations are used: Golden Eagle — GOEA; Peregrine Falcon — PEFA; American Kestrel — AMKE; Cooper's Hawk — COHA; Red-tailed Hawk — RTHA; Great -horned Owl — GHOW; Flammulated Owl — FLOW; Northern Saw -whet Owl =- NSWO.

COHA-1 (726345mE 4384715mN): Stick nest with fresh nesting material 30 ft high in a 35 ft Box Elder tree on main Clear Creek above Tom Canyon; pair of Cooper's Hawks defended the nest. COHA-2 (725200rnE 4386410mN): Stick nest with fresh fir bough in a box elder 25 ft above the ground in the riparian zone in Sheep Creek. Cooper's Hawk defended the nest site. COHA-3 (728220mE 4385615mN): Good stick nest 30 ft up in 40 ft boxelder. Adult COHA seen in the area two days; once perched on the edge of the nest. RTHA-1 (728075mE 4387030mN): Stick nest about 80 ft up on 160 ft cliff in Tom Creek. Adult Red -tail Hawk defended the nest against a GOEA. In addition to the active nests described above, there were several areas in which raptors were observed and nesting is likely to occur. For example, there were many sightings of GOEA in "Rattlesnake Basin" the southernmost basin on the east side of Clear Creek. On multiple occasions, WWE biologists observed Golden Eagles visiting stick nests on a large cliff with multiple nests, but the birds did not stay at any one nest long enough to prove it to be active. In a similar manner, GOEA were observed on several occasions in Tom Canyon, especially near the confluence of Tom and Clear Creeks. On one occasion, the birds landed on a large stick nest on the west side of Clear Creek, but it proved not to be an active nest. Many inactive GOEA nests are located in the upper portion of Clear Creek and also in Willow Creek. The large cliffs provide a wide variety of sites suitable for nesting; WWE biologists termed the small caves "potholes"; many were large enough to hold the large stick nests built by GOEA. Although only one active Kestrel nest is shown on the map, many adult Kestrels were observed along Clear Creek. These small raptors nest in holes in large cottonwoods or box -elders in the riparian zone; their nests are easily missed during surveys. Sharp -shinned Hawks (SSHA) were WestWater Engineering Page 8 of 24 pages 5/21/2007 observed on several occasions. Although no SSHA nests were discovered, they are likely nesters in Douglas Fir habitat on northeastern exposures in the upper canyon(s). 2.5 Birds of Conservation Concern (BOCC) other than raptors Table 2 provides the common name, scientific naive, habitat requirements and breeding status of birds on the BOCC list that could be found under the rims of the Clear Creek drainage.

Nests in sagebrush. • Uncommon: Breeding has been not been confirmed in Rio Blanco or Garfield Counties. 2.6 Procedures While no specific routes or techniques were used to survey for BOCC species, WWE biologists were ever vigilant for these species while watching cliffs and walking riparian areas and conducting other surveys. All songbirds observed were identified, either by visual reference or song, or by both methods. WestWater Engineering Page 9 of 24 pages 5/21/2007 All locations of birds were recorded using handheld GPS units and locations are reported as UTM coordinates (Datum: WGS84, Zone: 12S). 2.7 Observations The survey was conducted very early in the year; many neo -tropical migrants (songbirds) were just arriving at the end of April when the field work was terminated. Biologists noted a marked increase in the number of songbirds at the end of April. Four of the BOCC species listed above were observed by WWE biologists. Pinyon jays were recorded in mid-April and then again at the end of the month in PJ habitat in lower Clear Creek. Virginia's Warblers were seen on two dates at the end of April in lower Willow Creek and in the main canyon on the west side of Clear Creek at the mouth of Buck Gulch. A Black -throated Gray Warbler was observed on April 30 at the mouth of Tom Canyon. Although no Lewis's Woodpeckers were seen during this survey, WWE biologists are confident they are present in the Clear Creek area based on an observation by a WWE biologist during a previous survey. No nests of BOCC species were discovered. 3.0 Threatened, Endangered and Sensitive plant Species (TESS) 3.1 Background Information The occurrence and distribution of TESS are strongly influenced by geologic formations and the resulting soil types present in an area. Individual plant populations are scattered and usually only comprised of a small number of individual plants. This is primarily a result of specific soil and moisture requirements of each species and the high variability in the distribution and surface exposure of the layers within the formation. In the valley bottom and adjacent foothills in the lower portion of Clear Creek, three TESS plants could be found in the Wasatch Formation, particularly the Atwell and Shire members of the formation. DeBeque phacelia and adobe thistle require heavy clay soils subject to high levels of swelling and shrinkage. DeBeque milkvetch is often found on silt -clay soils which become hard - baked during the summer months. These three plants appear to be salt tolerant and may be associated with high selenium levels. The Atwell Gulch member of the Wasatch formation, which is comprised of reddish, heavy clay soils, is found in the mouth of Clear Creek, below Mt. Blaine on the west and Chimney Rock on the east. Plants associated with shale of the Green Rive Formation will likely occur at higher elevations on the ridges and steep slopes. Plants likely to occur on Green River shale include the Roan Cliffs blazingstar, sun -loving meadownre and Parachute penstemon. Piceance bladderpod also prefers soils of the Green River Formation, but can be found on more gentle slopes and in areas with shale outcrops. Three species, Naturita milkvetch, hanging garden sullivantia, and Uinta Basin hookless cactus, are less influenced by specific geological formations. Naturita milkvetch appears to be more associated with sandstone outcrops and sandy/gravelly flow patterns below the sandstone layers. Suitable habitat is often found on soils derived from the Wasatch Formation, but may also be found on the soils of the Green River Formation. This plant has a greater range, occurring into southwestern Colorado, Utah and New Mexico. Distribution is limited to sandstone ledges and canyons. WestWater Engineering Page 10 of 24 pages 5/21/2007 Hanging garden sullivantia is restricted to hanging gardens which grow beneath waterfalls and on cliffs below seeps. Potential habitat in the Clear Creek drainage is at the heads of the steeper drainages and on cliffs with a permanent water source. Uinta Basin hookless cactus is found in areas with deep soils, and within diverse vegetation associations. It is not specific to soils derived from the Wasatch or Green River Formation. The potential habitat in Clear Creek is restricted to areas under 6,000 ft in elevation, which is the upper limit of its distribution (Spackinan et. al. 1997). WWE biologists consulted the Colorado Rare Plant Field Guide (Spackman et al. 1997) to determine which species could possibly be present in Clear Creek. This reference, along with several years experience in field surveys for rare plant species, enabled WWE biologists to develop the list of plants contained in Tables 3 and 4 below. Table 3.

Various geologic formations. Several occurrences in Garfield County including East and West forks of Parachute Creek Sparsely vegetated open sunny steep shale talus slopes of the Green River formation Occurs in the Parachute Creek drainage Threatened (T), endangered (E) and candidate (C) are status categories related the Federal Endangered Species Act. These designations are the responsibility of the FWS and are granted to species through a formal listing process. Candidate species are those for which the FWS has sufficient information on their biological vulnerability to support proposals to list them as threatened or endangered. Table 3 includes the federally listed species. Sensitive is a designation used by the BLM and FS. Sensitive plant species are designated by the BLM State Director using criteria found in BLM Manual 6840 and from consultation with BLM field offices, the FS and the Colorado Natural Heritage Program (CNHP) The BLM sensitive plant list does not duplicate those species that are on the federal T&E list but does include some species proposed for listing or considered as candidates for listing (Table 4). 3.2 Procedures Based on soil types and slope, WWE biologists searched likely areas for plants. Searches were conducted as late as possible in April to allow for plant growth. Wasatch soils near the mouth of Clear Creek were searched as well as steep slide areas in the Green River Formation. Biologists did not search every slide, but selected areas that were representative of the extensive steep talus slopes in the canyon(s). The locations of the TESS plants discovered during the searches were plotted on aerial photographs. Because the waterfalls in CIear Creek and its tributaries were still carrying spring runoff, an extensive search for hanging gardens sullivantia was not conducted. WestWater Engineering Page 12 of 24 pages 5/21/2007 All locations of TESS plants were recorded using handheld Guidance Positioning System (GPS) units and locations are reported as UTM coordinates (Datum: WGS84, Zone: 12S). 3.3 Observations Although searches were conducted as late as possible in April to allow for plant growth, primarily plant material from the 2006 growing season was discovered. Two of the ten TESS species described above were found. Roan Cliffs blazingstar (MERH) and sun -loving meadowrue (THHE) were found on many of the steep slides that were surveyed. Figure 3 illustrates the distribution of the plants that were discovered. Note that only a portion of the many talus slopes were surveyed. Because WWE biologists did not have access to the slide habitats in Doe Gulch, Deer Park Gulch and the small canyons on the east side of Clear Creek south of Deer Park Gulch, those areas could not be surveyed. Many comparatively small slides exist on the west side of Clear Creek and only a few of these areas were surveyed for TESS plants. WWE biologists feel that a more thorough survey of the west side would result in many more TESS plant discoveries, especially of Roan Cliffs blazingstar, which appears to prefer more eastern and north-eastern aspect, while sun -loving meadowrue appears to thrive in full sun exposures. The smaller, ephemeral waterfalls high in the cliffs on the west side of Clear Creek may also provide habitat for hanging gardens sullivantia. Photos 5 and 6 show the steep rocky slopes searched by WWE biologists and an example of the plant materials they found. Photo 5.

Roan Cliffs blazingstar: old plant material from 2006, note new green growth 4.0 Weeds Previous reports by WWE biologists (WWE 2006a, b) have documented severe infestations of weeds and invasive noxious plants in Clear Creek. These reports concentrated on the Clear Creek drainage below the confluence of Tom Creek. This survey allowed the entire drainage below the rims to be surveyed for weeds/noxious plants. 4.1 Procedures In conjunction with raptor nest searches in riparian habitat, TESS plant surveys on the steep hillsides and other biological surveys, WWE biologists conducted foot surveys for weeds throughout the length of Clear Creek. In many cases, species determination was based on last year's growth; in some cases, basal rosettes were also present. WWE biologists have extensive experience in plant identification; weeds species were identified after consulting Colorado Flora: Western Slope (Weber and Wittmann 2001) and Weeds of the West (Whitson 1996). All locations of weeds and noxious plants were recorded using handheld GPS units and locations are reported as UTM coordinates (Datum: WGS84, Zone: 12S). 4.2 Observations Table 5 provides a list of the weeds recorded by WWE biologists in Clear Creek and its tributaries. Weeds on the Garfield County list, as well as those on all three lists (State A, B and C) published by the state of Colorado, plus one species known to be problematic by WWE biologists, are included. The table includes all species encountered by WWE biologists during WestWater Engineering Page 14 of 24 pages 5/21/2007 surveys in November, 2006 (WWE 2006a), except for cutleaf nightshade (Solanum triflorum) and field bindweed (Convolvulus arvensis). Little of the foliage of these plants persists to the following growing season and the tiny plants emerging this spring were missed by WWE biologists. Table S.

Photo 7. Heavy infestation of common mullein on west side of Clear Creek just above Tom Creek WestWater Engineering Page 15 of 24 pages 5/21/2007 Houndstongue is the most widespread weed that WWE biologists encountered during the surveys. It is found from the heads of the drainages to the mouth of Clear Creek, in the riparian as well as on steeper hillsides. The four thistle species and common mullein are probably in next in order of occurrence, with some patches of mullein so thick that biologists reported it "feels like walking on a wooly carpet". Photo 7, above, illustrates one of the heavy infestations of common mullein. This report contains no map(s) of weeds because the distribution of weeds and noxious invasive plants in Clear Creek is so widespread. 5.0 Waters of the United States 5.1 Background Information Waters of the United States includes lands likely to be within the jurisdiction of the COE under Section 404 of the Clean Water Act. WWE biologists and Geographic Information System (GIS) specialist performed an evaluation of the property to identify lands that may be within COE jurisdiction during the course of the biological surveys. Waters of the United States includes wetlands and drainage courses (including streams, ephemeral drainages that connect to streams via surface flow or subsurface connection), ponds, lakes and springs. Clear Creek has many tributaries; some have active flows year-round, some carry water during the snowmelt/spring runoff, others carry water only during major stonn events. A section of Clear Creek at the confluence of Tom Creek ceases to carry water during the late spring and summer. Surface flows reappear downstream, presumably from springs and subsurface flows. On many of the steep slopes on both sides of Clear Creek there are drainages that apparently carry significant volumes of water off the near -vertical cliffs and down to the valley floor. Many have prominent alluvial fans with no apparent stream channel that connects to Clear Creek. The water apparently is absorbed into the rocky, porous alluvial fan and is carried under the surface. 5.2 Procedures The GIS specialist for WWE used high quality aerial photographs, U. S. Geological Survey (USGS) topographic maps and Garfield County stream data to identify each drainage that appeared to connect with Clear Creek, either by surface flow or by suspected subsurface connection. In the field, WWE biologists recorded GPS locations of dry streambeds and active flows during surveys of riparian areas for weeds and wildlife species. When possible, the coordinates of the confluence of the dry streambed or side drainage with Clear Creek were recorded. 5.3 Observations Figure 4 illustrates the drainages that have been designated as possibly jurisdictional by WWE staff. It includes active streams, dry streambeds and wetlands. Drainages are numbered from south to north; the figure shows that nearly 80 waterways may fall under the jurisdiction of the COE. Wetlands WWE biologists recorded four potential wetland sites. There is a small wetland (WE -1) populated with rushes and sedges just under the Gibler Ditch; just east of this site is an area on the hillside populated with tamarisk (WE -2). A third suspected site (WE -3) is on the east side of Clear Creek just north of Scott Gulch. It is a small fenced -in area with willow or tamarisk. The fourth wetland (WE -4) is adjacent to the main channel of Clear Creek below the confluence of WestWater Engineering Page 16 of 24 pages 5/21/2007 Buck Gulch near a head gate. The exact coordinates of WE -2 and WE -3 were not recorded because biologists suspected the sites were on Shell property. Streams, Drainages, Ponds At the time of survey, water was flowing in the main stem of Clear Creek for its entire length, in Tom Creek, in Cottonwood Creek and in Willow Creek. These drainages, in addition to several drainages that were already dry at the time of the survey, are included as jurisdictional waterways. In addition, there are several drainages that carry an appreciable amount of water, especially during major storm events that do not have an apparent confluence with Clear Creek. WWE biologists suspect that these drainages have a subsurface connection. Figure 4 includes streams with an active (persistent) water flow, dry streambeds with a discernable connection with Clear Creek, and dry streambeds that have no surface connection. Springs and seeps As mentioned above, a segment of Clear Creek dries up in late spring and summer, but then reappears further south. Biologists noted three seeps or springs (see wetlands above), but the abundance of water during the survey made detection of additional springs or seeps impossible. 6.0 Aquatic Habitat 6.1 Procedures While surveying riparian areas for weeds, raptor nests and BOCC, WWE biologists took note of the condition of the aquatic habitat in Clear Creek. No water quality, macro -invertebrate or fish sampling was conducted. 6.2 Observations Overall aquatic and riparian habitat conditions are deemed poor primarily because of historic overgrazing in the drainage. Creek banks are incised, eroded and unstable due to continual removal of streamside vegetation (Photo 8). Sedimentation and the resulting "cementing" of stream substrate are evident, resulting in poor aquatic invertebrate production. There is some cottonwood regeneration occurring in sections of the creek, but very few willows can be found resulting in reduced stream shading. Lack of shade over the stream increases water temperature, especially in late spring and summer when water flow decreases, resulting in reduced insect production. 7.0 Other Wildlife Observations During the course of the surveys in Clear Creek, many other wildlife species and sign were observed and recorded. Wild turkeys, elk, deer and a few snakes (bull and garter) added variety for the biologists. Turkeys and elk use the entire drainage; mule deer were concentrated in the P.l habitat near the mouth of the canyon. As mentioned above, the number of species and individual songbirds increased throughout the month of April. Biologists encountered fresh bear droppings in upper Clear Creek and in Sheep Creek. These sites provide excellent habitat for bears, with stands of chokecherry, oak and other food sources that are important, especially in the fall as bears attempt to gain weight prior to winter. WestWater Engineering Page 17 of 24 pages 5/21/2007 Photo 8. Incised stream bank in middle Clear Creek; note tamarisk on stream's edge 8.0 Summary and Recommendations Biological surveys conducted by WWE biologists identified ten raptor species present in the project area and documented nesting by eight species of raptors. The presence of four non -raptor BOCC species was confirmed. Two species of TESS plants were observed and initial mapping of their distribution was accomplished. The widespread distribution of 14 species of weeds was recorded with several species occurring throughout the entire canyon. Waters of the United States were mapped. Although no intensive aquatic surveys were conducted, the overall condition of aquatic habitat in Clear Creek is deemed poor by WWE biologists. An abundance of wild turkeys, elk and other wildlife species was noted. The following sections provide recommendations for selected topics. 8.1 Raptors Activities associated with energy development in Clear Creek have the potential to impact raptor populations. In order to reduce the potential for impacts, it is important that construction and drilling activities be scheduled such that they do not interfere with breeding, nesting and brood - rearing activities. The following recommendations should be considered Best Management Practices (BMPs) for minimizing the effects of energy development on raptor populations. 8.1.1 Timine Limitations In areas of known raptor nesting, construction and drilling activities should not be scheduled between territory establishment and dispersal of young from the nest. If work is planned during the nesting season, areas of known and potential nesting should be inventoried by qualified biologists. Tinting limitation restrictions should then be considered and applied to all active WestWater Engineering Page 18 of 24 pages 5/21/2007 nests. WWE recommends temporal and spatial restrictions for activities near active nests based on BLM stipulations (BLM 1997), Colorado Division of Wildlife (CDOW) recommendations (Craig 2002) and literature review of nesting season timing for raptors in the Roan Plateau region (Andrews and Righter 1992, Kingery 1998, Poole 2005). These recommendations are summarized in Table 6 and illustrated on Figure 2. Table 6. Timing limitations and NSO recommendations for active raptor nests Species Buffer Zone - NSO Seasonal Restriction Red-tailed Hawk 0.33 mile 1 March - 15 July Swainson's Hawk 0.25 mile 1 April - 15 August Sharp -shinned Hawk 0.25 mile 1 April - 15 August Cooper's Hawk 0.25 mile 1 April - 15 August Peregrine Falcon 0.5 mile 15 March - 31 July Prairie Falcon 0.5 mile 15 March - 31 July Golden Eagle 0.25 mile + alt. nests 1 January - 15 July Northern Harrier 0.25 mile 1 April - 15 August American Kestrel * * Flammulated Owl 0.25 mile 1 April — 1 August Northern Saw -whet Owl 0.25 mile 1 March 1 August Northern Pygmy -Owl 0.25 mile 15 March - 15 July Long-eared Owl 0.25 mile 1 March - 15 July Great Horned Owl * * * American Kestrels and Great Horned Owls are relatively tolerant of human activity. Keep activity to a minimum during breeding season. 8.1.2 Habitat Fragmentation and Removal Fragmentation of wildlife habitat is a concern due to the rapid development of natural gas resources by a number of private companies. Habitat fragmentation is defined as an increased partitioning of intact vegetative communities that tends to reduce the suitability for wildlife occupancy. Fragmentation increases the potential for the establishment of non-native or invasive species which may out -compete preferred native species. When possible, new infrastructure should be constructed along existing pipeline and access road corridors to reduce habitat fragmentation in this area. Every effort should be made maintain the integrity of forested areas, both in the riparian zone and on north -facing hillsides, with an emphasis on protecting those areas where nesting is known to occur. Removal of trees containing raptor nests should be prohibited. 8.1.3 Future Monitoring Future monitoring of known nest sites as well as continued surveying for new sites by qualified biologists may allow insight into population trends and habitat requirements of species nesting in the region. Some portions of the drainage have not yet been thoroughly surveyed due to access and safety concerns. As development continues and access improves, these areas should be inventoried to allow implementation of BMP to minimize impacts on raptor populations. WestWater Engineering Page 19 of 24 pages 5121 /2007 8.2 Birds of Conservation Concern (BOCC) other than raptors Surveys later in the spring would allow BOCC species to arrive and establish breeding territories in the area. It is likely that additional BOCC species would be observed and nesting habitats could be delineated. 8.3 Threatened, Endangered and Sensitive Species (TESS) plants Surveys should be conducted later in the spring to allow for germination, flowering/fruiting of TESS plants, as well as searches in active and ephemeral waterfalls high on the canyon walls. 8.4 Weeds and Invasive Plants Weeds are so widespread in Clear Creek canyon that managers may feel there is no solution. However, weed reports previously written by WWE and cited in this report outline specific measures that can be taken to address the rampant weed issues in the drainage. 8.5 Waters of the United States To protect the integrity of Clear Creek waters and riparian habitat, precautions need to be taken when crossing or intersecting the waterways identified (Figure 4). Adequate barriers and filtration methods should be used to prevent and reduce soil from eroding into the water and riparian areas of Clear Creek and its tributaries. The Corps of Engineers should be consulted for Standard BMPs used in construction activities that intersect jurisdictional waterways. 8.6 Aquatic Habitat To better determine the current condition and potential for aquatic habitat(s) in Clear Creek, we recommend water quality assessment, a survey after runoff to determine which reaches of the stream maintain adequate flows, fish sampling and macro -invertebrate sampling. 8.7 Bears In recent years, the CDOW has experienced an increasing number of situations where conflicts have occurred between black bears and natural gas development. Most often incidents involve workers that have created problems at campsites (remote man camps) or around drilling sites where trash has not been protected and bears have been attracted in search of food. By their nature, black bears are not aggressive and prefer to avoid contact with humans. However, they are constantly searching for food and if they smell food trash, they can come in contact with humans. During times of drought or lack of seed/berry production due to frost, bears will be in a constant search for food. Intentional feeding of bears has occurred in the past and should never be allowed by employees. Intentional feeding almost always leads to unanticipated problems including direct contact with humans (human bites, breaking into cabins, trailers, trucks). In order to avoid bear problems, all potential sources of food attributable to workers should be eliminated from access by bears. Any trash containing food items produced on drilling sites and in man carnps needs to be protected from bears. Removal of trash containing food items and bear -proof trash containers are two possible solutions. This requires aggressive and persistent action to eliminate the opportunity for bears to obtain food items in and around production sites. WestWater Engineering Page 20 of 24 pages 5/21/2007 Black bear problems are best prevented by proactive measures rather than attempting to solve an ongoing problem. The CDOW much prefers avoidance to problem management. 9.0 References Andrews, R, and R. Righter. 1992. Colorado Birds: A Reference to Their Distribution and Habitat.
