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 Non -Conventional Gas (PBNCG) Project. The project will progress through the typical phases of natural gas production with exploration, expansion to a pilot phase (validating the exploration findings), and if the field is viable, 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 service and any other proposed utility improvements. Be specific. As part of the EPS development CNAEP proposes the installation and operation of a 2.6 million - gallon (350,000 cubic feet) Fresh -Water Pond. The facility will be located in the SW 1 /4 NW 1 /4 of Section 36, Township 6 South, Range 98 West of the 6th Principal Meridian (see Maps - Figure 2). The facilities will be used by CNAEP supply water for the EPS drilling operations. Chevron North American Exploration and Production Company Fresh -Water Pond Special Use Permit Piceance Basin Non -Conventional Gas Project 29021-003 1 Document No: 003-31-14-01 1.1 Location The proposed facilities will be located about 2.3 miles northwest of the end of County Road (CR) 211 in the Clear Creek drainage (Figure 2). The site can be accessed from Interstate 70, exit 62, by traveling north on local Road 45N. Road 45N north of De Beque 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. Traveling north of the intersection about 4.5 miles, one reaches the end of CR 211, where a gated fence is encountered (a location locally known as Hiner Gate). An existing ranch road continues north onto Chevron fee land. The Fresh -Water Pond will be located on about 1.6 acres of land along the west side of the access road (Maps - Figure 2). 1.2 Fresh -Water Pond Purpose Water is necessary for a variety of operations necessary for drilling natural gas wells. The water / drilling mud combination provides the necessary lubrication to allow the drill bit to advance, water is a necessary material for casing the well, and hydraulic fracturing (fracing) requires significant quantities of water. The Fresh Water Pond will provide the necessary water for these and other operations. On-site water supplies are necessary because of the remote location of these operations. Currently CNAEP has no industrial water rights in the vicinity, which eliminates direct access to water in the Clear Creek basin. The Fresh Water Pond also provides an on-site water supply in the event of a fire. 1.3 Hours of Operation Typical operations at the Fresh -Water Pond will be a 12 -hour shift, 7 days a week within the property boundaries. Water deliveries typically will be limited to daylight hours but on-site water transfers may occur as required. Water deliveries may be minimized or eliminated if a water treatment system is used to treat / dispose of the production water. Studies are underway to determine the economic feasibility of several water treatment systems. 1.4 Vehicles / Traffic / Regulatory Requirements A preliminary EPS traffic plan is provided as part of the EPS Preliminary Development Plan, which details estimates of traffic on area roads and highways along with possible mitigation measures. A period of increased vehicle traffic is anticipated until proposed mitigation measures can be implemented. Initial traffic associated with the site will be the grading and site preparation including delivery of gravel for the pad / access road and storm -water controls. 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 potentially the piping / valves associated with a water distribution system (currently under study). Once the physical installation is complete, water trucks will be used to fill the pond. Depending on the size of the truck mounted water tanks, it may require 20 to 40 truckloads per day for one to two months to fill the pond (multiple trucks may be used to expedite this process). Chevron North American Exploration and Production Company Fresh -Water Pond Special Use Pennit Piceance Basin Non -Conventional Gas Project 29021-003 2 Document No: 003-31-14-01 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. Once sufficient volume is available at the pond, water will then be trucked to the individual well pads on an as needed basis (dependent of number and size of frac tanks). The proposed water distribution could potentially eliminate the on-site water trucking. 1.5 Civil / Building / Structure / Equipment Specifications The Fresh -Water Pond area will be graded and then prepared with a 60 -millimeter geosynthetic liner. A vehicle access road and turnaround area will be provided. The access road and turnaround will be graveled in accordance with the final design (typically four -inches or 3/ -inch gravel). A grading permit will be submitted to Garfield County when the civil design is finalized. The Fresh Water Pond geosynthetic liner will be installed in accordance with vendor specifications. The liner installer / vendor will supply materials and perform work in accordance with all regulatory requirements and current guidance. The area will be graded as specified in Drawing 003-12-11-111-01 sheets 1 through 3 (see Drawings). Storm water / erosion controls will be used in accordance with the best management controls specified by the site Storm Water Pollution Prevention Plan (SWPPP) (see attached SWPPP and Construction Storm Water Permit). An addendum to the SWPPP for pond specific storm -water controls is provided in Drawing 003-12-11-061-001. Bi -weekly SWPPP inspections will be conducted to ensure site stabilization measures are adequate and / or identify areas that need repair / improvement. Topsoil will be stockpiled and stabilized for eventual site reclamation in accordance with specific SWPPP requirements. A site specific reclamation plan will be generated after the completion of the final civil design and provided to the County along with the revegetation bond. The site specific reclamation plan will follow recommendations provided in the NNWM Plan. Seed mixes used for site stabilization and revegetation will be in compliance with Garfield County Reclamation Standards. A gated, six-foot chain-link fence will be installed around the pond area to control access and prevent wildlife from becoming trapped in the pond. 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 Structural Specification / Regulatory Requirements Currently there are no structures planned at the Fresh Water Pond area. The proposed water distribution system may require a small control / pump house. The County will be notified if a significant structure is proposed for the site. Chevron North American Exploration and Production Company Fresh -Water Pond Special Use Permit Piceance Basin Non -Conventional Gas Project 29021-003 3 Document No: 003-31-14-01 1.7 Electrical Utilities / Regulatory Requirements Initial water transfers at the Fresh Water Pond will be limited to vehicle mounted pumps and hoses / valves. No on-site power will be required for these operations. The addition of a water distribution system may require the addition of on-site pumps, which would require some type of power. Typically these power requirements are met by an on-site generator, but a finalized distribution design will be required to determine the actual electrical requirements. Safety lighting may be added if night operations are required, which again would require some type of on-site power. 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 Fresh Water Pond area is not located in the floodplain. 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 has been infested with noxious weeds. ERM will conduct a supplemental survey of the area during the spring of 2007, with follow-up surveys as the project progresses. 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 hazardous materials that may be encountered. Upon finalization of the Temporary Office design, meetings will be held with the De Beque Fire Chief to determine if additional fire protection is required Chevron North American Exploration and Production Company Fresh -Water Pond Special Use Permit Piceance Basin Non -Conventional Gas Project 29021-003 4 Document No: 003.31-14-01 Portions of the pond liner will be sufficiently rough to allow the slope to be climbed in case of someone accidentally falling into the pond. Ropes leading to the pond interior will be provided every 50 to 100 feet to aid escape. Areas where water is delivered / removed will be posted to warn drivers of the slippage danger and these areas will be provided with hand rails and other safety equipment. The area will be fenced to prevent access by unauthorized personnel and wildlife. No outdoor cooking / fires will be permitted at the Fresh -Water Pond location. A Class ABC fire extinguisher will be provided at the loading / unloading point in the event of a vehicle fire. All personnel accessing the site will be trained on their proper operation. All employees and contractors will comply with the provisions of the CNAEP PBNCG 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 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 pennit and any other legal water supply intonnation, including a water allotment contract or an approved water augmentation plan to demonstrate that you have legal and adequate water for the proposed use. Up to 2.6 -million gallons of water will be stored in the Fresh -Water pond. Water will be supplied by a licensed subcontractor. Treatment of produced water may eliminate the need for an off-site water supply. Depending on the time required for loading / unloading, portable toilets may be provided at the Fresh Water Pond area. If this option is selected the units will be serviced at least twice a week by either Mountain West Oil Field Service & Supplies or Down Valley Septic. These contractors are currently undergoing review by CNAEP contracting to determine if the vendor meets specific contracting requirements. 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 003-12-11- 111-01 sheet 1. Figure 4 (see Maps) shows the existing county roads and general property owners within one -mile of the site. A preliminary plat of the Temporary Office area is provided in the Plat attachment. 4 Topographic Vicinity Map Submit a vicinity map showing slope / topography of your property, for which a U.S.G.S. 1:24,000 scale quadrangle map will suffice. Chevron North American Exploration and Production Company Fresh -Water Pond Special Use Permit Piceance Basin Non -Conventional Gas Project 29021-003 5 Document No: 003-31-14-01 The topographic vicinity map is provided as Figure 5 (see attached Maps). The steep cliffs in many portions of the project area represent a falling rock hazard. These issues will be addressed by the ESHIA process and possible mitigation methods will be incorporated into project planning and the site 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 6 (see Maps) also provides information about surrounding property owners. 6 Property Deed Submit a copy of the deed and a legal description of the subject property. The deed for the entire CNAEP Piceance Basin property is provided in the Deed attachment. 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: (l) 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; Chevron North American Exploration and Production Company Fresh -Water Pond Special Use Pertnit Piceance Basin Non -Conventional Gas Project 29021-003 6 Document No: 003-31-14-01 8.1 Water Supply System Vendor selection is currently underway to determine which company will provide water service to the Fresh -Water Pond. The most likely scenario involves transporting water from the Colorado River in 2,400- to 4,800 -gallon tanker trucks. Actual water delivery schedules will be affected by drilling rates, the number of drilling rigs, and the decisions surrounding the water treatment. Water used for drilling operations does not need to be potable. 8.2 Road Improvements / Issues CR 211 is scheduled for surface improvements (addition of 4 -inches of gravel) beginning in May or June of 2007. CNAEP is studying improvements needed to handle the well pad traffic on the existing dirt road that continues along Clear Creek. If significant modifications are made to the existing access road a driveway permit application will be submitted to the County. Permit submittal will be held until specific CR 211 improvements clarified. Improvements to CR 204 also are planned but there has been a delay due to the costs associated with the initial bids provided to the County. Negotiations are currently underway to obtain bids more in line with the County budget. Mesa County currently has weight restrictions assigned to the bridge that crosses the Colorado River at De Beque. The V.5-45.3 Bridge on 45 Road (Roan Creek) is scheduled for removal and replacement beginning in October 2007 and is expected to take about a year to complete. Heavy loads (>27 tons) and less than 15 -ft can take the Interstate 70 (I-70), De Beque exit (Exit 62), continue east on the frontage road to W.5 road and back to 45 Road (Roan Creek). Overweight vehicles greater than 15 -ft need to exit I-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). 8.3 Visual Effects The Fresh -Water Pond is located in a remote region of Garfield County and will have minimal visual effects on adjoining property owners. Visual effects include the physical presence of the pond and operational traffic. Outdoor lighting currently is not planned but if installed in the future it will be positioned downward to minimize visual impacts. 8.4 Reclamation and Revegetation Plan Once pond is no longer required the pond will be drained, the liner and gravel access road / turnaround will be removed, and the area will be returned to the original contours and planted with native vegetation. General details of the re -vegetation are provided in the IVNWM Plan and SWPPP and will be included in the final revegetation plan. 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 Storm Water Pollution Prevention Plan (SWPPP) and will be included in the final revegetation plan. Chevron North American Exploration and Production Company Fresh -Water Pond Special Use Permit Piceance Basin Non -Conventional Gas Project 29021-003 7 Document No: 003-31-14-01 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 & 5.03.08], 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 Fresh Water Pond supports operations associated with the development of natural gas, additional requirements must be met for Garfield County approval. The following details applicable information not provided in Sections 1 through 8 that are required by the supplemental regulations. 9.1 Environmental / Social Studies A Class III Cultural Resources Inventory (Carl E.

This SWMP addresses construction activities associated with dcvclopmcnt of the natural gas resources in the Skinner Ridge arca. This SWMP is intended to bc periodically updated as needed to address planned developments, new disturbances, and other changes nccdcd to manage storm water and protect surface water quality. 1.1 Storm Water Runoff Permitting Requirements The Federal Clean Water Act [Section 402(p}7 requires that discharges of pollutants 10 waters of the United Station from any point source be rcgulatcd by NPDES permits. 1n 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 bc rcgulatcd as an industrial activity and covered by an NPDES permit. In December 1999 the USEPA published final Phase ❑ NPDES regulations that cstablishcd application rcquircmcnts for storm water associated with construction activity for soil disturbances to be rcgulatcd as an industrial activity and covered by an NPDES permit. These regulations became effective July 1, 2002. Construction permits arc required for oil & gas activities that disturb 5 or more acres during the life of the project or arc part of a larger common plan of dcvclopmcnt. CDPHE considers a common plan of of and gas development to mean dcvclopmcnt of several welt pads and/or related infrastructure in a contiguous arca cithcr during the same time period or under a consistent plan for long-term dcvclopmcnt. 3 SKINNER RIDGE SWMP CHEVRON U.S.A., INC 1.2 Project Description and Background The Skinncr Ridge Common Plan of Dcvclopmcnt will bc located in Garfield County, Colorado within Townships 5 & 6 South. Range 98 Wcst. The town of Debcquc. Colorado is the nearest population center. The Skinncr Ridge arca is located approximately 14 miles north of DeSegue. The current drilling and dcvclopmcnt plan includes pad construction, access road improvemcnt/constntction, pit construction. installation of associated facilities, well drilling, well completion, well testing and pipclinc construction. The area of disturbance including thc natural gas well pads, the access roads and gathering system pipeline will be greater than five acres. 1.3 Project Owner and Operator The property owner and operator is Chevron Oil & Gas Corporation. Their address is: Chevron U.S.A. Inc. 11111 S. Wilcrest Houston, Texas 77099 Ph (981) 561-4991 The Chevron contact person for the projcct is Scan Norris. Mr. Norris can be contacted by phone at (970) 270-7517. Chevron will be in charge of al] aspects of this projcct. Contractor(s) will do the actual construction and grading but all work will be supervised by Chevron and all decisions will bc 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 Skinncr Ridge project arca will be located in Garfield County, Colorado within Townships 5 & 6 South, Range 98 West. The following is a list of the sections that are in the development arca: Township 5 South Range 98: Sections: 8, 17, 25, 27, 36 Township 6 South Range 98: Sections: 11, 12, 22, 23, 27, 28 In areas that arc 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 dcvclopmcnt consists of the construction of roads. pipelines, drilling pads and gas treatment facilities. The construction of the facilities in the development arca will be done using conventional cut and fill, trenching and earth moving techniques. Reclamation and final stabilisation 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 arc included in this SWMP. For well pads that will be constructed, BMPs will be installed prior to, during, and immediately following construction as practicable. Development of thc natural gas resource and construction of necessary improvements on this property will likely continue for the next 3 to 5 years, The dcvclopmcnt 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 thc Production (Operation/Maintenance). and the third phase is the Abandonment and final reclamation. Each work phase is briefly discussed below. 5 SKINNER RIDGE SWMP CHEVRON U.S.A., INC Development (Construction/Drilling/Completion/Reclamation) The development phasc includes the following activities; pad constnrction, well drilling, well completion, gas line installation, and pad arca reclamation. Pad reclamation is accomplished by backfilling thc reserve pit, contouring disturbed soils to conform with thc surrounding terrain, replacing thc stockpiled top soil, sccding of disturbed soil arcas in ordcr to reestablish a cover vegetation, and construction of erosion and sediment control structures. The completion of a well (gas production) generally triggers a one- year time period in which thc reclamation phase of work should bc completed. For the specific final stabilization seed mixturc please rcfcr to the Figure 2. Production (Operation/Maintenance) The production phase includes thc operation and maintenance activities during natural gas production. The typical equipment on a pad during thc 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 arc also installed during this phase of work. Reclamation activities during this phase include maintcnancc of rcvegetatcd areas and maintenance of the erosion and scdimcnt control structures. Natural gas wells in the Skinner Ridge arca arc projected to producc for approximately 20 to 30 years. Abandonment and Final Reclamation When the natural gas production of a well is exhausted it will be abandoned. Upon well abandonment each borehole will bc plugged. capped. and all surface equipment will be rcmovcd. Subsurface pipelines will be rcmovcd to specified locations and plugged. The pad arca wilt be reclaimed by contouring disturbed soils to conform to thc surrounding terrain, by replacing the stockpiled top soil. by sccding of disturbed soil areas in ordcr to reestablish cover vcgctation, 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. Any additional wells wilt need to bc added to the SWMP. Once thc 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 stabilisation 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 rcmovcd from this SWMP for sediment controls. However, if petroleum hydrocarbons or other chemicals impact stormwatcr as a result of industrial activities onsitc, the impacted stormwatcr will bc addressed by following a spill prevention control and countermeasures (SPCC) plan. SKINNER RIDGE SWMP CHEVRON U.S.A., INC 2.3 Runoff Characteristics Runoff characteristics arc based on site topography, soil type, and soil/vegetative cover. According to the NCRS, soils for the Skinner Ridge project arca consist of the following soil types: 1. Bicdsaw-Sunup gravelly loams, 10 to 40% slopes - is on sidc slopes of mountains and ridges. Native vcgctation is mainly juniper, sagebrush, shadscalc saltbrush, grcascwood, ephedra, yucca, and Indian riccgrass. Elevation is 5,100 to 6.600 feet. Bicdsaw soil is deep and well drained.

The runoff coefficient value prior to and after constnrction will range from 0.10 to 0.40: depending on the topography of each well pad. The pre -disturbance perccnt ground cover ranges from 60 to 85 perccnt. For specific pad perccnt ground cover information please rcfcr 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 constntction sites and natural gas dcvclopmcnt include: • Sediment resulting from erosion of soil stockpiles and other areas cleared of vegetation; • Leakage of fuels and lubricants from cquipmcnt and spills from fueling; • Trash and debris from clearing activities, construction materials, and workers; • Lcakagc or spills from storage tanks and process equipment associated with the natural gas development activities. 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. Petroleum products can also be potential storm water pollutants. These products arc 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, ctc.) present other potential pollution sources within thc construction site. Spills or leaks from potential sources arc 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 scdimcnt 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 crosion and scdimcnt controls to be used at active construction sites to minimize possible scdimcnt impacts to storm water runoff. The proposed erosion control features can include: • Placement of any topsoil stockpiles along thc cut -slope side of the pad to divert nun -on; • installation of silt fence, straw bales or diversion ditches at or below thc toc of fill slopes where located within 100 fcct of surface water drainages or whcrc steep slopes will likely result in rapid drainage from the location to nearby drainages. and; • Installation of check dams in areas of conccntratcd 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 upgradicnt areas away from construction areas, salvaged topsoil may be placed on thc uphill side of the road cut slope. The topsoil stockpile may be placed and graded to forma diversion berm that will direct surface water away from thc road. 4.1.2 Downhill silt fence Silt fence can be installed at the down gradient edge of thc 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 thc location to nearby drainages. Typical silt fence installation details arc given in Appendix B, 4.1.3 Hay bale check dams Hay bale check dams should be installed at suitable locations to slow thc conccntratcd flow of drainage water. Typical hay bale check dam installation details arc given in Appendix B. 9 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 runoffto 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 scdimcnt. 4.1.14 Diversion ditch Diversion ditches convey concentrated runoff of surface water from the areas of disturbance to a stabilized arca. The ditch should be excavated to a depth and width that can handle the expected. flows. The ditch should 1,e sloped so that the water velocities do not cause excess erosion. The ditch can be lined with check dams. vegetation, rock andlor 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 malting installation details arc given in Appendix B, 4.1.16 Additional BMP references The structural and non-structural BMPs listed above arc 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 arc 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 intemet at httn:/lwww.blm.tov/bmp/Gold Book Draft v12.pdf. • For construction BMPs the Urban Drainage and Flood Control District, a Colorado frons range group of city and county agencies has developed a BMP manual that is available on the internet at http://www.udfcd.orriusdcrn/vol3.htrn • For construction BMPs and surface stabilization methods, the Alabama Soil and Water Conservation Committee has developed "Erosion Control, Sediment Control and Stormwater Management on Constriction Sites and Urban Areas, Volume I Developing Plans and Designing Best Management Practices."

Best Management Practices Field Guide," which is available on the interact at hit: +/ww w.b I nt.go v tb m pl fie l d %20 gu i de. h t m 4.2 Storm Water Management Controls Structural 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 arca and maximize distance from surface water drainages. as practicable). Other developments on the property, primarily existing andlor 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 arc noted, they should be reported to the Site Manager and/or 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 will 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 suitable 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: 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 othcr surfaces. In case of a spill or leak, soils contaminated with petroleum products will be contained and removed to a proper disposal site. Proposed soil erosion and sediment control practices will aid in retention of spills or leaks. Use of secondary containment and drip pans will reduce the likelihood of spills or leaks contacting the ground. Proposed maintenance and safc storage practices will reduce the chance of petroleum products contaminating the road site. Oily wastes such as crankcase oil, eans, 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 bc conducted to identify Teaks and initiate con'cctivc actions, if needed. The following guidelines for storing petroleum products will bc used. • All product containers will be clearly labeled. • Drums will bc kept off the ground within secondary containment and stored under cover if needed. • Fuel tanks will be stored within 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 Icaks 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 Mana.gcment Additional materials will be used and stored on site for use in construction. These materials will bc stored appropriately and managed to minimize spills and leaks. Storage arcas will bc regularly inspected and any minor spills or leaks will be cleaned up i mmediately. Materials Manatement 14 SKINNER RIDGE SWMP CHEVRON U.S.A., INC The construction contractor will maintain a laydown or staging arca for cquipmcnt 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 sealed containers and regularly collected and disposed of at off-site, suitable 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 will bc 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. There will be no major equipment overhauls conducted on site. Equipment will be transported off site for major overhauls. Cleanup of trash and discarded materials will be conducted at the end 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 maintcnancc 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 thc inspections. 2. Inspections will cover these arca of the construction site: • Disturbed areas without stabilization, • Material storage areas, • Best Management Practices (BMPs), • Surface water diversions, • Downgradicnt 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. 4. Completed and stabilized sites will bc inspcctcd at least once per month. 5. A log of inspections will be kept. 6. Water quality will bc assessed for all receiving streams and discharge areas during • ach inspection. 7. Disturbed areas and material storage areas that arc exposed to precipitation will be inspcctcd for evidence of pollutants entering nearby drainages. 8. Check dams. silt fences, and other BMPs will be inspcctcd for evidence of deterioration, under -cutting, and build up of sediment. Sediment will be removed when it has built up one-third to one-half the height of the hay bales or silt fence. 9. Roads used for vehicle access will bc inspcctcd for evidence of off-sitc scdimcnt transport. 10. Eoliowing each inspection, the SWMP will be modified as necessary to include additional controls designed to correct identified problems. Revisions to thc SWMP will be made within 7 days of the inspection. I I. An inspection report summarizing the scope of thc inspection, thc name of thc person conducting thc 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. 11 Actions taken to modify any storm water control measure will be recorded and maintained with the SWMP. 13. If no deficiencies arc found during thc inspection, the report will contain certification that thc site is in compliance with the SWMP. Signatures will bc 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 anticipated storm event. Chevron U.S.A. or designated contractor(s) will maintain, on-sitc 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 arc anticipated from thc project. Possible exceptions include fire prevention/suppression or dust control activities. IR SKINNER RIDGE SWMP CHEVRON U.S.A., INC 7.0 FINAL STABILIZATION Arcas which have been disturbed arc considered to be stabilized when a uniform vegetative cover with a density of 70 percent of the pre -disturbance levels has been established or when an equivalent permanent, physical erosion reduction method is in- place. For thc specific final stabilization seed mixture please refer to Figure 2. Arcas at which arc not used for facilities. access roads, materials storage yards. or other work areas will be stabilized with vegetation. Arcas that arc stabilized with vcgctation will bc considered to have achieved final stabilization when a uniform stand of vegetation with a density of at [cast 70 percent of thc pre -disturbance has been established. Other areas which may include facilities, access roads, materials storage yards, and other work areas will bc 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 thc 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 accordancc with a system designed to assure that qualified personnel properly gather and evaluate thc information submitted.

Changes in this General Permit Several notable changes from the previous General Permitfor Construction Activities have been incorporated into this permit. Most of the changes are related to the Phase 11 revision to the stormwater regulation in the Colorado Discharge Permit System Regulations (5CCR 1002-61), effective March 2, 2001. Signlficanr changes are listed below: 1. Permit coverage is now required for construcrioa sites that disturb I to 5 acres (i:e., small construction activities). Allowances have been made for small construction activities to comply with the requirements of a Division -approved Qraling Local Program (refer to section VI below for a discussion of Qtaling Local Programs) in place of many specific requirements in the Permit, including requirements to submit an application, inactivation notice. and fees to the Division. Refer to Part I.A.3 of the Permit and section VILA of the Rationarefor more details. 2. The requirements to submit with the application the Township, Range, section and quarter section of a site and a7st ofany other environmental permits for the site have been removed. 3. Inactivation requirements have been changed to allow small construction activities that submit applications indicating a completion date 12 months or less from the start of construction activity to be authorized for a predetermined period from 3 to 12 months The permit certification will include the automatic expiration date for permit coverage. This expiration date will be in place of the requirement to submit an Inactivation Notice. 1f permit coverage beyond the expiration date is needed (i.e., the site has not been finally stabilized), the permittee must submit an extension request form to the Division at least 10 days prior to the expiration.

The Rationale discussion on the Exemptions far Small Municipalities (Secrian 111.8) has been changed to include the March 10, 2003 deadline far permit coverage for municipally -owned industries. This did not involve any changes to the permit 11. BACKGROUND As required under the Clean Water Act amendments of 1987, the Eoi ironmentai Protection Agency (EPA) has established a framework for regulating municipal and industrial stormwater discharges. This framework is under the National Pollutant Discharge Elimination System (NPDES) program (Note: The Colorado program is referred to as the Colorado Discharge Permit System, or CDPS, instead of NPDES). The Water Quality Control Division ("the Division) has stormwater regulations (5CCR 1002-61) in place. These regulations require specific types of industrial facilities that discharge stortnwaler associated with industrial activity (industrial storrnwater), to obtain a CDPS permit for such discharge. The regulations specifically include construction activities that disturb 0170 acre of land or more as industrial facilities. Construction activities that are part of a larger common plan of development which disturb one acre or more over a period of time are also included A. General Permit The Water Quality Control Division ("the Division') has determined that the use of general permits is the appropriate procedure for handling the thousands of industrial stormwater applications within the State. B. Permit Requirements Thi spermit does not require submission of effluent monitoring data in the permit application or in the permit itself It is believed that afully implemented Stormwater Management Plan (SWMP) should be sufficient to control water quality impacts. The permit requires dischargers to control and eliminate 1he sources of pollutants in stormwater through the development and implementation of a SWMP. The plan must include Best Management Practices (BMPs). which will include pollution prevention and source reduction measures. This will constitute BAT and BCT and should achieve compliance with water quality standards. The narrative permit requirements include prohibitions against discharges ofnon-stormwater (e.g. . process water). Refer to Part 1.C.2 of the permit In addition. as a condition of this permit, the permittee is required to pay the annual fee as described in the Water Quality Control Act. Failure to submit the requited fee when due and payable is a violation of the permit and will result in enforcement action as discussed below_ Permittees will be billed for the iniad permit fee within a few weeks ofpermit issuance. Some construction activities may be required to comply with a Qualifying Local Program in place of meeting several of the specific requirements in this permit. Sites covered by a Quaking Local Program may not be required to submit an application for coverage ora notice of inactivation and may not be required to pay the annual fee. Refer to Section VILA of the Rationale for further information. C. Violations/Penalties Dischargers of stormwater associated with industrial activity, as defined in the Regulations for the State Discharge Permit System (5CCR 1002-61), which do not obtain coverage under this or other Colorado general permits, or under an individual CDPS permit regulating industrial stammerer, will be in violation of the Federal Clean Water Act and the Colorado Water Quality Control Act, 25-8-101. For facilities covered under a CDPS permit, failure to comply with any CDPS perrnu requirement constitutes a violation. Civil penalties for violations of the Act or CDPS permit requirements may be up to 510,000 per day. Criminal pollution of state waters is punishable by fines of up to 825,000 per day. COLORADO DEPARTMENT OF PUBLIC HEALTH AND ENVIRONMENT, Water Quality Control Division Rationale - Page 3- Permit No. COR -030000 111. STORMWATER DISCHARGES ASSOCIATED WITH CONSTRUCTIONAL 7VI7Y The Storrriwater regulations require that stormwater discharges associated with certain industrial activities be covered under the permit program. Construction activity that disturbs one acre or more during the life of the project is specifwcaily included in the listed industrial activates. Construction Activity Construction activity includes clearing, grading and excavation activities. Construction does not include routine maintenance performed by public agencies. or their agents to maintain orrginal fine and grade. hydraulic capacity, or original purpose of the facility. Definitions of additional terms can be found in Part I.D of the Permit. Stormwater discharges from construction activity require permit coverage. except for operations that result in the disturbance of less than one acre of total land area which are not pan ofa larger common plan of development or sale. A larger common plan of development or sale is a contiguous area where multiple separate and distinct construction activities may be taking place at different times on dOferenr schedules under one plan. B. Topes of Activities Covered This permit is intended to cover most new or existing discharges composed entirety ofstormvvater from construction activities that are required by5tate regulation w obtain a permit. This includes stormwater discharges associated with areas that are dedicated 10 producing earthen materials, such as soils. sand. and gravel, for use at a single construction site. These areas may be located at the construction site or at some other location. This permit does not authorise the discharge of mine water or process water from such areas. This permit also includes stormwater discharges associated with dedicated asphalt plops and concrete plants located al the construction sites. C. Types ofActivities NOT Covered This permit does not cover stormwaterdisciarged from construction sites that is mixed with stormwater from other types of industrial activities, or process water of any kind. Other types of industrial activities that require stormwater discharge permits pursuant to different sections of the regulations (Regulation 5 CCR 1002-61, Section 61.2(e)(iii)(A-l. K)], are not covered by this perms. This permit also does not cover the discharge of process water. If the construction =filmy encounters groundwater, a Construction Dewatering Discharge Permit (Permit Number COG 070000) must also be obtained in order to discharge this groundwater from the excavation site. An application for this permit can be obtained from the Division at the address listed in Part IA.4.0 of the Permit. D. Exemptions for Small Municipalities The Inter :oda!Surface Transportation Efficiency, Act of 1991 (Section 1068(c)) added an exemption to the stormwater regulations for municipalities with less than 100,000 Population. The term municipality" includes cities, towns. counties, special districts or any entity created by or pursuant to Stare law. Stormwater discharges associated with construction activity for facilities or sites that are owned ar operated by a small municipality are not required to apply for or obtain a stormwater permit until March 10, 2003. (Note: This exemption does not apply to other, privately owned construction sites within the same small municipality) COLORADO DEPARTMENT OF PUBLIC HEALTH AND ENVIRONMENT. Water Quality Control Division Rationale - Page 4. Permit No. COR -030000 IV COVERAGE UNDER THIS GENERAL PERMIT Under this genera! permit, operators of stormwater discharges associated with construction activity maybe granted authorisation to discharge stonnwater into waters of the State of Colorado. This includes stormwater discharges associated with industrial activity from areas that are dedicated to producing earthen materials. suck as soils, sand and gravel, for use ata single construction .site. and dedicated asphalt plants and dedicated concrete plans. This permit does not pre-empt or supersede the authonry of local agencies to prohibit, restrict or control discharges of stormwater to storm drain systems or other water courses within theirjarsdiction. Authorization to discharge under the permit requires submittal ofa completed application form arida certafrcafon that the SWMP it complete, unless the sate is covered by a Qualifying Local Program. Upon receipt of all required information, the Division may allow or disallow coverage under the general permit. V. APPLICATION AND CERTIFICATION At least ten days prior to the commencement of construction activities (Le.; the initial disturbance of soils associated with clearing, grading excavation activities. installation of structural BMPS, or other activities), the operator of the construction site shall submit an original completed application which includes the signed cerlifradon that the SWMP is complete. In order to avoid confusion during processing, original signatures are required for the application to be considered complete. For small construction sites only, if rhe site is covered by a Qualifying Local Program (see below), submittal of an application is nor required For the purpose of this permit, the operator" is the person who has day-to-day control over the project. This can be the owner. the developer, the general contractor or the agent of one of these parties, in some circumstances. At different times of a construction project, dWerent types of parries may satisfy rhe definition of 'operator' and the certification maybe Transferred as roles change (Note - Under the Federal regulations. this application process is referred to as a Notice of Intent. or NOL For internal consistency with its current program. the Division wilt continue to use the term applicarron.) An outline of the permit application requirements is found in the permit at Part J.A.4.b. If this general permit is applicable, then a certification will be developed and the applicant will be certified under this general permit. VI. QUALIFYING LOCAL PROGRAMS For stormwater discharges associated with small construction activity (i -e, one to five acre sites). the permit includes conditions that incorporate approved qualifying local erosion and sediment control program (Qualifying Local Program) requirements by reference. A Qualifying Local Program is a municipal stormwater program for stormwater discharges associated with small construction activity that has been formally approved by the Division The requirements for Qualifying Local Programs are outlined in Part 61.8(12) of the Colorado Discharger Permit System Regulations (also see the Division's "Qualifying Local Programs for Small Construction Sites - Application Guidance). Such programs must impose requirements to protect water quality that are at least us stria as those required to this permit; A. Approval Termination: A Qualing Local Program may be terminated by either the Division or the municipality. Upon termination of Division approval of Quaking Local Program, any small construction ociiviry required to obtain permit coverage under Section 61.3(2)(h) of the State Discharge Permit System Regulations shall submit an application form as provided by the Division, with a certification that the Stormwwvzter Management Plan (SWMP) is complete as required by Part 1.4.4 of the Permit, within 30 days. R Approval Expiration: Division approval of Qualtying Local Program will expire with this general permit on June 30, 2007. Any municipality desiring to continue Division approval of their program must reapply by March 31, 2007. The Division will determine if the program may continue as a approved Qualifying Local Program.

Coverage under a Oualifviee Local Program - For Small Construction Sees Onty For small construction sites (disturbing less than 5 acres) covered under a Qualifying Local Program (see Section VI abm'e) et.,Iy,ce rat„ permit requirements scaly asputlined below. The loval program must have been formally designated by the Division to qualify. Most municipalities have some type of local program and may require permits andfres. However, simply having a program in place does not necessarily mean that it is a qualifying program and that a State permit is not required. The local municipality will be responsible for notifying operators and/or owners that they are covered by a Qualifying Local Pregnant. A list of municipalities with Qual8ying Local Programs is also available at hap://www.cdphe.state.co.usheq/PermitsUnit/wgcdpeet.html. The Division reserves the right to require any owner or operator within the jurisdiction ofa Qualifying Local Program covered under this permit to apply for and obtain coverage under the fit!! requirements of this permit. 1. Permit Coverage- Ifa construction site is within the jurisdiction ofa Qualifteng Local Program, the operator of the construction activity is authorized to discharge mom:water associated with small construction activity under this general permit rvttham the submittal of an application to the Division.

B. Storm water ManaPs) Prior to commencement °fconstruetion. a stormwater management plan (SWMP) shalt be developed and implemented for each facility covered by this permit. A certification that the SWMP is complete must be submitted with the permit application. The SWMP shall identify potential sources of pollution (including sediment) which may reasonably be expected w affect the quality ofstormwater discharges associated with construction activity from the facility. In addition, the plan shall describe the best management practice (BMPs) which will be used to reduce the pollutants in stammerer discharges from the construction site. Facilities must implement the provisions of their SWMP es a condition of this permit. The SWMP shall include the following items: 1. Site Description 2. Site Map 3 BMPs for Stormwater Pollution Prevention 4. Longterm Stormwater Management 5. Other Controls 6 Inspection and Maintenance 7. Signatory Requirements and Availability 8.

C Nloniroring Sampling and testing ofstormwater for spocifrc parameters is not required on a routine basis under this permit. However, the Division reserves the right to require sampling and testing on a case-by-case basis, in the event that there is reason to suspect that compliance with the SWAP is a problem, or to measure the effectiveness of the BMPs m removing pollutants in the effluent. D. arcAN_I rection Active Construction sites must inspect their stormwater management controls at lean every 14 days and after any precipitation or snowmen event that causes surface erosion. At sites where construction has been completed but a vegetative cover has not been established, these inspections must occur at least once per month. Atsites where winter conditions exist, !rupee -lions are not required during the period that the winter conditions exist. For all of these inspections, records must be kept on file. Refer to the permit at Part I.C.S for detailed requirements of these inspections. E. Revision of SWMP Based on the results of the inspections (see D. above), the description of potential pollutant sources and the pollution prevention and control measures identified in the SWMP, and the control measures themselves, shall be revised and modified as appropriate as 100n as practicable after such inspection. Modification of control measures shall be implemented in a timely manner, but in no case more than 7 calendar days after the inspection. ? The inspection record shall be made available to the Division upon request Regular submittal of an anneal report is not required in this permit Annual Fee The permitree is required to submit payment of an annual fee as set forth in the Water Quality Control Act. Permittees will be billed for the initial permit fee within a few weeks of permit issuance and then annually, based on a July 1 through June 30 billing cycle. For small construction activities, if application was made for coverage with a completion date 12 months or les s„from the start of construction activity. a fee will be assessed based on the estimated number of calendar -quarters the site is active. Projects going beyond that time will be billed the standard annual fee. H. Inactivation Notice When a sae has been finally stabilized in accordance with rhe SWMP, the operator of the facility shall submit an Inactivation Notice that is signed in accordance with Pan I.E,I of the permit. The content of thelnactivation Notice is described in Part 1.4.6 of rhe permit. A copy of the Inactivation Notice form will be mailed to the permittee along with the permit certification. Additional copies are available from the Division. An exception to the requirement to submit an inactivation has been inchtded in the renewed permitfar Small Construction Sites that will beftnallystabilised within 12 months of the beginning of construction activities. In such cases, the permit certification will indicate the automatic expiration date. Ifpermu coverage is needed beyond that daze. an extension request form must be submitted to the Division at lean 10 days prior to the expiration date.

If the new responsible party will not complete the oamferfornt, the permit may be inactivated if the permittee has no legal responsibility, through ownership or contract, for the construction activities at the site. In this case the new operator would be required to obtain permit coverageseparately. 1 Duration ofPermit The general permit will expire on Jane 30, 2007. The permittee's authority to discharge under this permit is approved until the expiration date of the general permit. Anypermitee desiring continued coverage under the general permit mast apply for recertification under the general permit at least 90 days prior to its expiration date. Nathan Moore March 11, 2002 VII CHANGES MADE AFTER PUBLIC NOTICE Several comments were received from the Environmental Protection Agency (EPA), Changes based on these comments and additional interna! review are discussed below: R- The EPA commented that language needs to be added to the permit addressing the certification requirements for inspection reports. Part 1.E.1 ofthe Permit requires that all reports submitted to the Division include specific certification language. Because site inspections required by Part 1.C.5 ofthe permit are not submitted to the Division, they are not covered under Part I. C.5 of the Permit or Regulation 5 CCR 1002-61. Section 61.4(1)(f), which require specyic certification language. However, Regulation 5 CCR 1002-61, Section 61.8(4)0)(i0(B) does require that the permittee maintain a record summarizing the inspections that includes a certification that the site in compliance with the plan and the permit. Therefore, language has been added to Part I.C.5 ofthe Permit, requiring that a signed statement be intruded with all records of inspection on the status of compliance at the site. B. The EPA recommended that the Permit and Rationale be changed to indicate that the application is due ten days prior to the commencement of construction activities. instead of prior to the anticipated date of discharge. The Division agrees that this wording is preferable and more accurately indicates the Division's existing interpretation of the regulations. These changes have been made. C. The EPA expressed concern with requiring a permittee to transfer permit coverage in cases where the new responsible party may not be cooperative. Language has been added to the Permit and Rationale clarifying that termination of permit coverage is allowed when the permittee 110 longer has any legal responsibility through ownership or contract for the construction activity. D. The EPA commented on the lack of a definition for the terms "receiving water" and "ultimate receiving water". A definition has been added to the Permit, and the term "ahimate receiving water" clarfied io indicate that it means the first named receiving water, if the discharge initially goes to an unnamed ditch or storm sewer.

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 tetTace 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 offrcinale with a heavy riparian deciduous shrub and woodland over story comprised of mountain boxelder, Acer riegundo 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 loam, 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 (MRCS, 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 (Pascopyrum sinithii) and basin wildrye (Leymus cinereus). For moderate, loamy slopes, needle and thread (Hesperostipa comata comata), bluebunch wheatgrass (Pseudoroegneria spicatum spicatum), Indian ricegrass (Achnatherum lrymenoides) western wheatgrass, Wyoming big sagebrush (A. t. ivyomingensis), and winterfat, (Krascheninnikovia Janata) 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 lrystrix) and shadscale saltbush (Atriplex 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 1 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 mapped. Table 1.

Recommended Treatment It is important to know whether the target is annual, biennial, or perennial to select strategies that effectively control and hopefully eliminate the target. Treatment strategies are different WestWatei Engineering Chevron Clear Greek 8 Inch Pipeline IVNWMP Pacte 4 of hi depending on plant type and are summarized in Tables 2 and 3. 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. 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 112" - 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. WestWater Engineering Chevron Clear Creek 8 Inch Pipeline IVNVVMP Page 5 of 14 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, Onob;ychis 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 harrowing. Furrowing can be done by several methods, the most simple of which is to drill seed perpendicular to the direction of slope in a prepared bed. Other simple imprinting methods include deep hand raking and harrowing, always perpendicular to the direction of slope. Herbicides: Difficult species respond better to 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 WesiWater Engineering Chevron Clear Creek 8 Inch Pipeline (VNWMP Page 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: 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 7. Typical meadow with burdock. Photo 8. Seed bearing burdock. Photo 9. Seed bearing musk thistle.

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, Ceutorhynehus 1ltura, 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-mycorrhizal 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 VfAMF. The latter are applied to weed patches and are WestWater 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.

PLS/AC *WWE recommends accepting no other cultivar for this site. (MRCS, 2006a), Colorado Natural Heritage Program, 1998. Seeding rate should be doubled for broadcast application. Preferred seeding method is multiple seed bin rangeland drill with no soil preparation other than simple grading to slope and 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 Wes/Water Engineering Chevron Clear Creek 8 Inch Pipeline IVNWMP Page 9 of 14 • 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.

Commercial Applicator Recommendations A certified commercial applicator is a good choice for initial control efforts. 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 1-70 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 advised 9/25/200F 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 will any employee place themselves, or allow themselves to be placed, into a life-threatening situation. The following priorities will govern 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 wit 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 8 Contractors) associated with the Skinner Ridge Delineation Project (Pieance Creek/Debeque. 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 tog 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 individual's 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 facilitiyls: Building Energy Type Utility Shut-off Location Temporary On -Site Office — Drilling or tests 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 will use the logbook, verbal communication, cell or satellite phones and/or radios at the muster point to account for at personnel. If necessary, available, pre -designated personnel may initiate a search for any missing person as long ash 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 Bloodbome 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)1970-283-1041 (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 Facilityls ▪ 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-hazordous location. All -Clear Signal: When employees have been evacuated from any buildings 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 all -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 All 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 employees 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.

He/she provides specific direction for emergency action based upon information available regarding the incident and response capabilities and initiates emergency procedures, nduding 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 t0 comply with 29 CFR 1910.38(3). The on- site personnel and their alternates responsible for coordinating site evacuation efforts are listed in Table 7-4. The s4e relies upon the off-s4e 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 S stems 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 itis 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 mules 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 08 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 lime the evacuation alarm sounds. Personnel exiting the site gamer at a designated assembly point. To determine that everyone has successfully exited the site, personnel will be accounted for at the assembly site. a 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 orgenlzatiens. 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 350ut 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 responsibilities, 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 tire 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 equpmerl to minimize potential ignition sources • Use spark arrestors on ergines where applicable Carry incipient Stage fire fighting equipment (up to 200 ABC extinguisher) in vehides and they (300 ABC extinguishers) will be staged do all pad IOCatiois Individuals wrII be trained in Indpient stage fire fghfing tech(queS and will respond according to their training to suppress any accidental fres Will create defensible spaces in One 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.

I3ox 3543 Grand Junction, Colorado 81502 BLM Antiquities Permit No. C-52775 Submitted to Bureau of Land Management Grand Junction Field Office 2815 H Road Grand Junction, Colorado 81506 Abstract Grand River Institute (GRI) conducted a Class 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 on 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 of a total of 166 acres of private property and 40 acres of BLM land. The survey and report preparation were conducted by Carl E. 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 31" and June Is' 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 rcconunendations 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 (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 (50F425) was previously field evaluated as eligible for listing on the NRHP. 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 of the 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 reconunended. ii 'fable of Contents Introduction 1 Location of the Project Area 1 Environment I Summary of Files Search and Literature Overview 2 Study Objectives 4 Field Methods 4 Results 4 Site Significance 5 Site Description 5 Discussion 7 Summary of Site Evaluations and Recom►nendations 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, Jiro Conner and Dana Archuleta. A files search was completed on 19 May 2005, and the field inventory was carried out on May 3 I5' and June 151 of 2005. The survey was done to meet requirements of the Federal Land Policy and Management Act of 1976, the National Historic 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 Area 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; 6" 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 the area has continued since (Young and 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 shrublands, 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 mamrnals into the surrounding mountains. There, mule deer, elk, coyote, and black bear are connrnnon, 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). Summary 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 area. This information is important in the interpretation and evaluation of the cultural resources that were expected to be found. The piles search identified three historic sites within the project corridors. Two sites (5GF424 and 50F5425) are structures near the mouth of Clear Creek and one site is reportedly an historic race track (50F351), 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 Historical Society entitled Colorado Plateau Country Historic Context (I -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 Willia►n 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 them but also by so naming the ditches. Accordingly, one will also find the familiar names of Charles Creek, Joe Newman, A.S. Hianebaugh, Henderson Frashier, Tom King, George P. Anderson, George Hayes, and W.A. DcLaMatyr 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 Bcque'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 until a stone school house was built in 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 (NRI -IP), 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 (NHPA) 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 thein for inclusion in the NRHP. 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 are associated with the lives of persons significant in our past; or c) that embody the distinctive characteristics of a type, period, or method of construction, or that represent the work of a master, or that possess high artistic values, or that represent a significant and distinguishable entity whose components may lack individual distinction; or d) that have yielded, or may be likely to yield, information important in the prehistory or history. 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 OAI-IP Site Form (available at the BLM and OA1-IP). 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. Much 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 fortn 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, fi ve- horizontal panel, plywood doors. The gable ends and the upper portion of the entryway have cedar shingle siding in a coursed pattern. The east 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 stem 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 door 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 aqui is currently in use. This structure is referenced in a booklet entitled, "Cattle and Shale, 1884-1984, A Story of Roan Creek and De Bcque" in the section that discusses families and ranching on upper Roan Creek. The description from pages 13 and 14 is as follows: "A conununity hall, "Highmore 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-Iirncbaugh 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 form 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 are 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 2W1H 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/mudroom 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 Beque," but none was found. Despite this, the estimated time of construction is ca. 1930. Evalu4tion 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 (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) 8 was previously field evaluated as eligible for listing on the NRNP. Site 5GF425 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 5GF351 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 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. 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 listorical 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 runs 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 large 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 Iikely 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.

Whitewash on vegetation surrounding the nest. Unknown raptor 12S 730820 4377413 Nest determined to have been active, with whitewash on vegetation below nest, which was in a 75 ft box - elder. 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 pH -ion -juniper along Clear Creek and on the westward portion of the pipeline bisects possible Uinta Basin cactus habitat but no plants were observed.
