CNAEP is the operator and 100 -percent surface/mineral owner of about 40,000 acres north of De Beque, Colorado. The company also controls an additional 75,000 acres of severed mineral rights in the vicinity. Development of this natural gas field is referred to as the Piceance Basin Natural Gas Development Program (PBNGDP). The program will progress through the typical phases of natural gas production with exploration followed by early phase production, when equipment / operations are optimized for regional conditions, and depending on physical findings and economic conditions, development of the full 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 are primarily located within the Clear Creek drainage, a tributary to Roan Creek (see 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, communications), storage areas, pipelines [water, gas, produced water (water and condensate mixture)], and processing / treatment equipment. Operations will include road construction, equipment transfer, facilities installation, drilling, well installation and development, material supply, production processing, and general operations and maintenance. Assuming favorable economic conditions and field production the program could be ramped up to about 2,000 wells (100+ well pads) within the next 10 years. CNAEP is implementing their internal Environmental, Social, and Health Impact Assessment (ESHIA) process for the PBNGDP. 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. 2 BACKGROUND Early in the 20th century natural gas reserves were identified in the Piceance Basin but the nature of the geological formations and technical limitations made the reserves uneconomical to develop. Natural gas in these types of areas is referred to as tight gas, which means that it is trapped in unusually impermeable, hard rock, or sandstone/limestone formation. Geological assessment of the Piceance Basin, in particular the Williams Fork Formation, has shown that the gas is trapped in discontinuous sand bodies that are the remnants of ancient sandy creek beds. A combination of increasing demand together with higher prices and recent technological advances has now made development of these reserves feasible. Because of these favorable factors, CNAEP made the capital investment to determine the extent of natural gas resources underlying land previously purchased for oil shale reserves. Beginning in 2005 and continuing into 2006, 13 -delineation wells were installed and partially placed into production. Gas volumes were sufficient to prompt the company to move forward to the next phase. The EPS phase will be used to determine whether or not to proceed to full field Chevron North America Exploration and Production Company Piceance Basin Plan of Development Piceance Basin Natural Gas Development Project 1 Document No. 29021-003.000-31-14-01 rev. 1 development and the pace of such development. Economic factors and physical gas field characteristics may affect the nature and scale of the full field development. 3 CNAEP PROJECT SPECIFIC PROCESSES In addition to evaluation of the economics of the EPS, a number of CNAEP processes and procedures will be implemented to ensure project success. Safety is the first on the list. All operations will be evaluated to determine possible hazards / risks with focus on eliminating unsafe procedures or developing mitigation plans. All CNAEP and subcontractor personnel will be required to complete mandatory safety training with daily safety meetings to discuss operations to be performed that day. The company does not tolerate non-compliance with their safety program. Because there is no assurance that even the best safety plan can anticipate all scenarios, CNAEP develops site specific Emergency Response Plans (ERP) for each of their projects. The ERP generates contingency plans to prepare for accidents or natural events such as fires or severe weather events. Local coordination with emergency service providers is a basic part of the ERP process. Regulatory compliance also is high on the list of internal CNAEP processes. All CNAEP controlled operations must be in compliance with local, state, and federal requirements. Prior to entering into an agreement with subcontractors, each company must document that they will observe all project related regulations. For example, a company providing drinking water to the site must show they have a license to provide the service, are obtaining the water from a certified potable water source, and are observing local weight restrictions on area roads. A CNAEP process currently underway for the PBNGDP is their internal Environmental, Social, and Health Impact Assessment (ESHIA). The ESHIA process is designed to integrate project needs and site specific regulations and community concerns. It also identifies problem areas and attempts to develop mitigation plans prior to construction or initiation of operations. ESHIA is a tool to aid and inform engineering design and project management. When properly implemented the ESHIA provides real time feedback to the engineering design and construction to minimize or mitigate local project effects. 4 PRELIMINARY EARLY PRODUCTION SYSTEM DEVELOPMENT PLAN The following is a description of the current EPS Development Plan, which essentially is a snapshot in time. Because of the iterative nature of any early stage project, frequent changes are to be expected. Efforts will be made to inform stakeholders when project decisions result in significant changes. 4.1 Location The site can be accessed from Interstate 70, exit 62, by traveling north on local Road 45N. Road 45N north of De Beque is known as Roan Creek Road/Drive and transitions to CR 204 at the Garfield / Mesa county line. The EPS project roughly begins at the intersection of CR 204 and CR 211 located about 12.5 miles north northwest of De Beque, near the confluence of Clear Creek and Roan Creek. The official access point is located at the end of CR 211, locally known as Hiner Gate, about 4.5 miles north of the CR 204 & 211 intersection. Chevron North America Exploration and Production Company Piceance Basin Plan of Development Piceance Basin Natural Gas Development Project 2 Document No. 29021-003.000-31-14-01 rev. 1 4.2 Local Setting Proposed facilities and operations for the EPS will be located along the Clear Creek valley, a tributary to Roan Creek. The area is a deeply cut box canyon in a regional plateau, the Roan Plateau. Elevations vary from 5,000 to 6,000 feet in the canyon to 8,000+ feet on the plateau. An escarpment tops the canyon walls with the valley fill consisting of mixture of fractured rock from the escarpment and debris flows from the underlying less consolidated sediments. Springs and intermittent streams originating on the plateau flow into perennial and ephemeral streams that traverse the valley. The Clear Creek riparian zone contains the heaviest vegetation with populations of cottonwood and other deciduous trees. Portions of the area were historically irrigated to provide pasture for livestock and wildlife and the irrigation ditch areas provide an altered habitat that supports increased vegetation. Moving out of the riparian zone into the drier zones one encounters typical low herbaceous prairie species such as sagebrush and scattered Pinon and Juniper trees. Significant portions of the valley slopes are barren but north -facing slopes can contain spruce and fur trees with interspersed sagebrush at the lower elevations. A threatened plant species locally know as De Beque buckwheat reportedly is present in the area. All of these areas are vulnerable to noxious and invasive weed populations, which has been identified as a problem in the Clear Creek drainage. Mule deer and elk are the major game species in the area along with populations of bighorn sheep, black bear, wild turkey, and greater sage grouse. There also are potential populations of native trout. Raptor nests are evident in the area including Cooper's hawks, red-tailed hawks, great -horned owls, and flammulated owls. The Bureau of Land Management has identified the habitat as ideal for a number of sensitive and migratory birds. One of the few remaining herds of wild horses roams the area, which the local residents use as a tourist attraction. 5 EARLY PRODUCTION SYSTEM FACILITIES / OPERATIONS 5.1 Major Project Components The EPS will incorporate both existing and new facilities. Existing facilities include the 13 delineation wells with typical wellhead equipment, an aboveground flexible gathering pipeline, and well pad gas separation equipment / tanks (tanks hold combination of produced water and natural gas condensate). These operations are currently serviced by a number of subcontractors and CNAEP personnel from the Grand Junction office. Proposed infrastructure / facilities include the following (see Figure 1): • Upgrading of CR 204 and 211, in coordination with Garfield County (CR 211 improvements were completed in May 2007) • Temporary Office • Central Man Camp • Fresh Water Pond • Cuttings Pit Chevron North America Exploration and Production Company Piceance Basin Plan of Development Piceance Basin Natural Gas Development Project 3 Document No. 29021-003.000-31-14-01 rev. 1 • Four Drilling Pads with Two Service Pads • Pipelines— Natural Gas, Water, Condensate / Produced Water • Central Production Facility (FIuid Separation, Gas Compression, Condensate Storage) • Water Treatment System • Water Management Ponds • Thirty -Inch Natural Gas Pipeline (connection to regional pipelines) • Communications Towers • Office / Shop / Warehouse / Laydown Yard • Gravel Pit 5.2 EPS Details 5.2.1 Road and Highway Issues CNAEP and Garfield County are coordinating to upgrade the existing access roads including portions of the 9.5 miles of CR 204 and 4.0 miles of CR 211. Garfield County initially placed the CR 211 project out to bid, but the received bids were in excess of the available funds. The County has since decided to work with the bidders to try to get the costs in line with existing budgets. County road work then shifted focus to surface improvements on CR 211 to prepare for the increased traffic volume. This was a general maintenance project, which included adding gravel to the existing surface. Vendor selection delays will affect the CR 204 upgrade schedule, possibly postponing improvements until late 2007 with construction phased according to weather. Mesa County currently has special weight restrictions on the bridge that crosses the Colorado River at De Beque (loads limited to less than 10 tons). The V.5-45.3 Bridge on 45 Road (Roan Creek) is scheduled for removal and replacement beginning in October 2007 (potentially earlier), an activity expected to take about a year to complete. Heavy loads (>27 tons) and less than 15 -ft can take the Interstate 70 (1-70), 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 1-70 at Exit 75 (Parachute) and continue west on the frontage road toward De Beque to W.5 road and back to 45 Road (Roan Creek) north of De Beque. Another transportation issue associated with shipments along the I-70 corridor is the closure of the eastbound lanes at the Hanging Lake Tunnel east of Glenwood Springs due to a large crack in the tunnel ceiling. All traffic through this section of I-70 will be routed through the westbound lane until repairs are completed and result in major traffic delays certain times of the day. 5.2.2 Temporary Office A temporary field office is proposed on Chevron property slightly to the northwest of the end of CR 211. Office facilities are required for planning and coordination of on-site operations, centralized emergency response capabilities, and general site security. Facilities in this area are needed because of the remote location of the drilling operations. Available facilities in De Beque are not suitable for these operations and would have required additional use of CR 204 and 211. Alternative nearby facilities (e.g., Parachute or Grand Junction, Colorado) would require additional commuting time and again increase traffic on local roads. A permanent office is in the planning stage the EPS / Full Development transition phase but construction will be dependent on the production results. Currently the plan is to use the Chevron North America Exploration and Production Company Piceance Basin Plan of Development Piceance Basin Natural Gas Development Project 4 Document No. 29021-003.000-31-14-01 rev. 1 temporary office facilities for about one year, but production schedules may extend that timeframe. The Garfield County special use permit may need to be extended if that scenario develops. Proposed facilities at the temporary office include five manufactured homes configured as office facilities (one smaller building will serve as the site security trailer for vehicle control); utilities including power and communications, potable water supply (initially a tank), and sewage management (storage tank); communications tower and associated equipment building; and fuel depot (one unleaded gasoline and one diesel fuel tank). Specific details concerning the Temporary Office can be found in the Garfield County Special Use Permit application. 5.2.3 Central Matz Camp Because of the limited housing in the vicinity and the need to reduce traffic on local roads, a Central Man Camp is proposed. A location about 0.6 mile north of the CR 204 and 211 intersection has been selected. The facility will be used throughout the EPS phase of the project and into the full development phase (as needed). These facilities will be used by the drilling rig crews who will operate on 12 -hour shifts (drilling operations are scheduled for 24 hours a day, 7 days a week). No catering service is planned but the facility will be equipped with kitchens, which will require crew to make occasional off-site trips for supplies. The proposed man camp will consist of two manufactured homes supplied with utilities including power and communications, individual sewage treatment system (ISDS), and a potable water storage tank. A non-exempt drinking water well is proposed for the location, but several other options (centralized water system) are currently being evaluated. The resident population for the camp will be maintained at less than 24 unless adverse weather results in additional stranded personnel. Specific details concerning the Central Man Camp can be found in the Garfield County Special Use Permit application. 5.2.4 Fresh -Water Pond A lined, 2.6 -million gallon fresh -water pond to supply drilling operations water is proposed for a location near the confluence of Clear Creek and Tom Creek, about 2.6 miles north northwest of Hiner Gate. The pond will provide the necessary storage for the early drilling operations. Current planning includes a proposed pipeline to transfer water from near De Beque to reduce water truck traffic, but depending on the timing of facility installations, a limited number of water trucks may be required. Also once production has sufficiently ramped up, production water should be available in sufficient quantities to maintain drilling operations with only limited water import requirements. Water quality requirements for drilling operations are currently under study. Tanker trucks will initially be used to transfer water from the ponds to the well pads, but a water distribution system is being planned to eliminate this requirement. Specific details concerning the Fresh -Water Pond can be found in the Garfield County Special Use Permit application. Chevron North America Exploration and Production Company Piceance Basin Plan of Development Piceance Basin Natural Gas Development Project 5 Document No. 29021-003.000-31-14-01 rev. 1 5.2.5 Cuttings Pit A lined cuttings pit is proposed for a location about 1.8 miles northeast of the intersection of CR 204 and 211. The pit will be used for the drill cuttings generated by the drilling operations and have a capacity of 567,000 cubic feet. Sufficient initial storage will be available on the individual well pads, but additional space will be required as operations ramp up. Specific details concerning the Cuttings Pit will be included in the Garfield County Special Use Permit application expected to be submitted in July. 5.2.6 EPS Drilling /Service Pads CNAEP will utilize two Helmerich & Payne, Inc. state-of-the-art, Flex -4, directional drilling rigs for the EPS. These rigs allow up to 22 wells to be drilled from a single pad. Depending on local topography and knowledge of the gas field, up to four well pads will be installed per section [in accordance with Colorado Oil and Gas Conservation Commission (COGCC) regulations]. The EPS includes operations associated with four drilling pads and two service pads located along Clear Creek and Tom Creek near the confluence. Four well pads, 598-26AV, 598-35BV, 598-25AV, and 598-25BV, have been selected for this phase of the project. Two service pads, 598-35AV and 598-25-4 (one of the delineation well pads), will be used to provide additional storage for drilling operations. The service pads will utilize existing well pads or pads identified for future drilling operations. The EPS drilling pads will be constructed in accordance with the Colorado Oil and Gas Conservation Commission (COGCC) regulations and guidelines. The pads will contain the drilling rig, drilling / hydro -fracturing (fracing) supplies and equipment, and technical support trailers. The service pads will be used for storage of drilling pipe, fracing supplies, tanks, and general equipment. After the completion of the wells a variety of well pad equipment is installed for early processing. Pad equipment performs the following functions: gas stream pressure reduction, fracing / formation sand capture and removal (during initial well cleanup phase), gas / Iiquid separation (produced water and condensate), and transfer via pipelines to the Central Compression Facility for further processing. Pads 598-26AV, -35BV, -25AV, and -25BV also will house man -camp facilities for the supervisory and technical support staff associated with drilling operations. Details of these facilities were provided to Garfield County in a special use permit submitted by Cordilleran Compliance Services, Inc. 5.2.7 Pipelines — Natural Gas, Water, Condensate /Produced Water Production will require pipelines to transfer natural gas, water, and produced water (water and condensate mixture) to the appropriate facilities. Current planning is to consolidate these pipelines into a central corridor to minimize land disturbance. The corridor will be sized for both the EPS and full field development. Production from most of the existing wells is currently collected using a four -inch flexible gathering line. The flex -line transfers the product to well pad 598-36-1 where additional water Chevron North America Exploration and Production Company Piceance Basin Plan of Development Piceance Basin Natural Gas Development Project 6 Document No. 29021-003.000-31-14-01 rev. 1 and condensate are removed. The natural gas is then transferred into another flex -line that delivers it to a compression facility on the Roan Plateau. The flex -line has been scheduled for replacement with an 8 -inch line that was permitted in December 2006, but decisions were made to reroute the line, requiring permit re -submittal. The mixture of condensate and produced water is currently trucked from each pad to a processing facility. The EPS production will require a new gathering system consisting of 8- to 10 -inch pipelines (depending on number of attached wells), which will transfer wet gas to the Central Production Facility (see Section 5.2.8) for processing. Four -inch lines are currently planned to transfer the condensate / produced water mixture from each well to the separator and tanks at the Central Production Facility. Processed produced water generated by the Central Production Facility will be piped to the Water Treatment Facility for additional treatment (see Section 5.2.9). Current plans are to periodically truck condensate from the Central Production Facility tanks to a processing facility. Natural gas from the Central Production Facility will be transferred to the project 30 -inch production delivery pipeline (see Section 5.2.11) using a dedicated 12 -inch pipeline. Significant water will be required for drilling operations including water for well casing completions and fracing operations. In order to meet these needs a temporary water line has been proposed that will deliver fresh water from the De Beque area to the site. The water will be stored in the Fresh Water Pond and the Water Management Ponds (see Sections 5.2.4 and 5.2.10) until needed for operations. Water transfers to the well pads early in the project will need to rely on water tankers, but the goal is to install the pipelines as soon as possible to reduce truck traffic. Additional details of the pipeline corridor will be provided when the facility Pipeline Development Plan Permit Application is submitted. 5.2.8 Central Production Facility - Fluid Separation, Gas Compression, Condensate Storage A Central Production Facility for gas and condensate / produced water processing is proposed for an arca near the confluence of Clear Creek and Tom Creek, about 2.6 miles northwest of Hiner Gate. Facility operations will include gas drying and compression, produced water / condensate separation, and condensate purification and storage. The Central Production Facility will process production from the four EPS well pads. The wet gas stream from the pads will be dehydrated at this facility using a glycol gas dehydration system. The system will be maintained in heated enclosures to protect the operation from weather extremes. The dehydrated gas will then be transferred to the compression station where it will be compressed and introduced to the 30 -inch pipeline (see Section 5.2.11) for delivery to regional pipelines. The condensate / produced water from the wells will be transferred into a separator that will remove the majority of the condensate. Condensate will then be transferred to a series of tanks for storage until it can be trucked to a processing facility. Separated produced water will be transferred to a proposed Water Treatment Facility (see Section 5.2.9) to remove any remaining hydrocarbons and potentially remove the solids (process selection still underway). Early Chevron North America Exploration and Production Company Piceance Basin Plan of Development Piceance Basin Natural Gas Development Project 7 Document No. 29021-003.000-31-14-01 rev. 1 calculations indicate that the majority of the treated water will be used for continuing site operations. Additional details of the Central Compression Facility will be provided when the facility Special Use Permit Application is submitted. 5.2.9 Water Treatment Facility Processed produced water leaving the Central Production Facility will be piped about 250 yards south to the proposed Water Treatment System. At a minimum all produced water will be treated to remove hydrocarbons. Water treated only to this level would still contain suspended and dissolved solids, primarily salts, which typically are composed of common ions such as sodium and calcium. However, these solids may contain specific constituents that require specialized disposal. The initial process at the Water Treatment Facility would be another separator with a longer retention time. This step will remove an additional portion of the carryover condensate released by the Central Compression Facility. However, the produced water will still contain dissolved hydrocarbons and a limited amount of condensate. Current plans are to use an electrocoagulation (EC) unit to remove remaining hydrocarbons and some of the produced water dissolved solids. An electrocoagulating unit in simplest form is an electrolytic cell with an anode and cathode where an electrical current is passed through the media (produced water). The anode is sacrificed but in the process, contaminants in the water coagulate into larger particles that drop out of suspension. The coagulated solids drop to the bottom of the unit while the effluent continues on to either a holding pond or tank or to the next level of treatment. The coagulated solids sludge will be transferred to a holding tank, pond, or additional treatment for dehydration or offsite disposal. The EC effluent requires additional treatment to remove the remaining dissolved solids. Two membrane technologies are currently being evaluated for the EPS solids removal. Additional technologies are being evaluated for the potential full field development. Early production operations may begin prior to the completion of the membrane system, which will require the EC effluent to be temporarily stored in a Water Management Pond (see Section 5.2.10). However, the effluent water quality may be acceptable for fracing operations and can be used for this purpose until the membrane system is available. Discussions and studies are underway to determine a use for excess water coming from the membrane treatment system. Effluent from these systems is typically of such high quality that minerals need to be added back in to make it usable. Several options are being explored including releasing it for beneficial use or to regional surface water. A number of water rights issues need to be addressed if this approach is pursued. The membrane systems also generate solids that will require proper disposal (TBD). Additional details of the treatment system will be provided when the facility Special Use Permit Application is submitted. Chevron North America Exploration and Production Company Piceance Basin Plan of Development Piceance Basin Natural Gas Development Project 8 Document No. 29021-003.000-31-14-01 rev. 1 5.2.10 Water Management Ponds Drilling operations require significant quantities of water and depending on the well field may generate large quantities of produced water. Facilities are necessary to manage these waters. A proposed, double -lined, Water Management Pond(s) would be used for this purpose. A two -cell pond with a total capacity of 19.3 million gallons is proposed for an area west of the Central Compression Facility. The two cell design provides the capability to handle both fresh water and partially treated produced water (hydrocarbons removed). Effluent from the EC system will be stored in nearby tanks initially with an option of constructing a proposed effluent pond (6.3 million gallon capacity). A second two -cell Water Management Pond (19.3 million gallon) is under study near the confluence of Deer Park Gulch and Clear Creek. Pond cells containing partially treated produced water will be equipped with specialized apparatus designed to prevent / minimize entry by water fowl and wildlife. A number of systems are currently being evaluated and "lessons learned" from other operators are being considered. Additional details of the Water Management Pond will be provided when the facility Special Use Permit Application is submitted. 5.2.11 Thirty Inch Natural Gas Pipeline The EPS natural gas will be transferred from the Central Production Facility to regional pipelines using a 30 -inch pipeline. The regional pipelines are located on the Roan Plateau about 8 miles to the north northwest of the compression facility. Several support buildings will be required for the actual connections to the pipelines, which will house necessary valves and meters. A Pipeline Development Plan Permit Application was submitted to the County in June and is currently under review. 5.2.12 Office /Shop / Warehouse /Laydown Yard A long-term office, shop, warehouse, and yard storage facility is proposed for an area about 2.1 miles north of the intersection of CR 204 and 211. The facilities will provide support for the EPS and potential full-scale project. All temporary office operations, most field storage, and large equipment storage will be transferred to this main facility. Space requirements and site layout are currently in the preliminary design phase. The facility will be designed to meet not only the EPS requirements but the possible full-scale operations. The site design will include a properly sized ISDS and permitted water well (or system). Because of the long -lead time on the water well permits, a temporary water supply system may be initially required. Additional details of these facilities will be provided when the Special Use Permit Application is submitted. Chevron North America Exploration and Production Company Piceance Basin Plan of Development Piceance Basin Natural Gas Development Project 9 Document No. 29021-003.000-31-14-01 rev. 1 5.2.13 Five Communication Towers Site topography requires the installation of five communication towers to provide adequate coverage for the project area during EPS. The first tower will be installed at the Temporary Office location. Additional towers will be installed near the Cowboy Chapel, Smitty Point (Section 2, Township 6S, Range 98W), Parachute Knob (Section 16, Township 5S, Range 97W), and Tom Creek. Four of the towers were detailed in a Special Use Permit approved by the County in February, 2007. The application for the fifth tower at the Temporary Office location was recently submitted and is currently under review. 5.2.14 Gravel Pit A source of aggregates will be required for road improvements and facility construction. CNAEP has acquired property located about three miles southwest of De Beque with suitable gravel reserves for that purpose. Negotiations are underway with an existing aggregate company to determine the best method to utilize this resource. Details of the gravel pit will be provided after the evaluations are complete. 6 EARLY PRODUCTION SYSTEM PROJECT EFFECTS Large scale projects normally result in a variety of environmental effects. Projects also impact local communities in a variety of ways. Habitat loss can result in more wildlife / people interactions, construction activities can increase local traffic, schools can have insufficient teachers to handle the influx of students, etc. CNAEP has implemented the ESHIA process to identify these types of effects and explore possible mitigation measures. The concept is to minimize negative effects but recognize there will be limits on possible solutions. The following is a general description of some of the issues that will have possible impacts on the area and community. This is only a sampling of the possible impacts. 6.1 Wildlife The Roan Creek and Clear Creek Basins contain significant populations of wildlife. The area draws large numbers of hunters every year, generating income for the local community. Deer and elk herds are the most obvious wildlife and are typically visible along CR 204 and 211. Increased traffic along these roads potentially will result in additional vehicle / wildlife collisions. The ESHIA process has identified specific wildlife corridors that are currently being mapped. A variety of mitigation measures are under consideration (e.g., wildlife fences, increasing the visual buffer along the road, special reflectors, etc.). Other mitigation measures could include strict enforcement of speed limits through a variety of controls. Chevron North America Exploration and Production Company Piceance Basin Plan of Development Piceance Basin Natural Gas Development Project 10 Document No. 29021-003.000-31-14-01 rev. 1 6.2 Visual Effects The majority of the EPS project will occur in remote regions of Garfield County having limited visual effects on a small group of local land owners and lessees. Major visual effects are primarily the lighting associated with the 24-hour operation of the drilling rigs. In some areas rig lights will shine on the surrounding canyon walls, making it visible for some distance. Possible mitigation measures will be evaluated as part of the ESHIA process and implemented as determined by project management. After the completion of the drilling activities the wellhead piping and equipment will be painted to blend into the surrounding terrain (using guidance such as that provided in the Bureau of Land Management Gold Book) and portions of the well pads will be reclaimed, minimizing the visual effects. Other visual effects will include the temporary buildings and material storage areas. These areas will be reclaimed as the facilities are retired from use. 6.3 Noise The project area lands are zoned as agricultural / rural, which means that noise levels must be limited to 55 decibels using the A -weighted Fletcher—Munson curve [db(A)] from 0700 to 1900 and 50 db(A) from 1900 to 0700. These limits are enforceable at a distance of 25 -feet from the property line (Colorado Statues, Title 25, Article 12, Section 103). The statutes do allow noise levels to increase up to 10 db(A) for up to 15 minutes per hour between the hours of 0700 and 1900. In agricultural / rural areas periodic, impulsive, or shrill noises at a level of 50 db(A), daytime, and 45 db(A), evening, are considered a public nuisance. Drilling operations and the associated traffic will generate considerable noise. The remote location will provide the primary noise mitigation, but studies will be performed to document problem areas and determine the appropriate measures. Sound barriers / enclosures may be provided where necessary. 6.4 Integrated Vegetation and Noxious Weed Management Plan Continuing studies are evaluating the project area for noxious weed issues (e.g., Chevron Clear Creek 8 Inch Pipeline Integrated Weed Management Plan, Garfield County, Colorado, WestWater Engineering, December, 2006). The studies have found noxious weed exposures or infestations (from both Garfield County and State of Colorado lists) throughout the majority of the project area. Additional studies are being completed as proposed site facility locations are selected, followed by implementation of weed control that follows best management practices. 6.5 Preliminary Traffic Assessment A preliminary traffic study was performed in September, 2006, to determine current traffic patterns on CR 211 and the associated side roads. The study showed of the 800 to 900 peak mid- week vehicles heading north out of De Beque, about 87 -percent turned on to CR 213 to access the existing Occidential Petroleum facilities. About 4 -percent of the remaining traffic continued north on CR 204, with about 9 -percent turning on to CR 211 to access the CNAEP property. Chevron North America Exploration and Production Company Piceance Basin Plan of Development Piceance Basin Natural Gas Development Project 11 Document No. 29021-003.000-31-14-01 rev. 1 Construction activities and drilling operations will add significantly to the use of both CR 204 and 211. Early traffic estimates resulted in numbers as high as 500+ vehicles a day. After those numbers were identified, efforts were made to reduce vehicle numbers where possible. Water tanker trucks were determined to be a major portion of the overall traffic, which resulted in the evaluation of a pipeline from the De Beque area to the project. While the pipeline represents a capital expenditure, it also represents a cost savings over trucking and reduces wear and tear on local roads. Another method to reduce local traffic includes centralized parking areas with shuttle services going to the site. Areas for parking lots and shuttle service requirements are currently being evaluated to determine how feasible this is for the project. Certain activities will still require multiple vehicle trips including delivering well construction supplies (drilling mud, fracing sand, well completion material), piping, facility equipment (tanks, separators, compressors, generators, etc.), and general construction equipment (backhoes, excavators, etc.). However, not all activities will occur at the same time, which will allow some of these loads to be staggered. Exact traffic volumes are still under study by CNAEP and the ESHIA process. Rough estimates at this time are on the order of between 100 and 350+ additional vehicle round trips. However, the upper limits typically would not occur on a daily basis. Specific installations will require short-term traffic increases, such as delivering pipeline for construction or specific facility equipment. Tables la and lb show an example of the type of information that was evaluated for this preliminary traffic assessment.

Through the ESHIA process CNAEP also is evaluating mitigation measures such as limiting truck traffic during hours when school children in De Beque are traveling between their homes and school. Other options include trimming sagebrush along CR 204 to reduce vehicle / wildlife collisions. This preliminary assessment will be developed into a full traffic study as designs are finalized in accordance with ESHIA evaluations and CNAEP management decisions. 6.6 Reclamation A reclamation plan and associated bond will be submitted to the County for each facility. The COGCC also requires all well pads to be reclaimed within a specified time period. Reclamation efforts will include the removal of unnecessary equipment including gravel pads, regarding the area to close to the original contours (when possible), replacement of the top soil, planting the site with the appropriate seed mix (including factors such as elevation), and maintaining the site until the vegetation is sufficiently re-established (following both COGCC and County requirements). The ultimate purpose of the reclamation effort is to minimize or remove signs of the development. Chevron North America Exploration and Production Company Piceance Basin Plan of Development Piceance Basin Natural Gas Development Project 13 Document No. 29021-003.000-31-14-01 rev. 1 Addendum A Temporary Office Changes to the Temporary Office permit application since initial submittal: Project name has been changed to Piceance Basin Natural Gas Development Program (originally called Piceance Basin Non -Conventional Gas Project). The proposed trailer layout has been modified to position two trailers facing one another with a common sidewalk between the trailer sets. The updated drawings will be submitted as part of the building and grading permit applications. The parking area has been extended to accommodate the twenty-four vehicles (originally twenty were specified). The updated drawings will be submitted as part of the building and grading permit applications. The originally proposed two tank fuel depot, 1,000 gallons of diesel and 1,000 gallons of unleaded gasoline, has been modified to two 3,000 or 4,000 gallon tanks. The area at the south end of the Temporary Office enclosure has been designated a storage area for small storage buildings and miscellaneous equipment and materials. The area is visible only from an occasionally occupied farm house that is leased from Chevron. The generator at the Temporary Office has been downgraded from a 1,000 kW supplemental / backup gas-fired generator to a backup / emergency generator rated at 40 kW with an annual runtime of 40 hours or less. A Perkins 1106D, Tier III rated generator has been selected for the site. At the County's request a water well location has been identified near the site (in case the site occupancy exceeds one year). Alternative water supplies are currently being evaluated including a central pipeline that potentially could supply water to all project facilities. The goal of that evaluation is to reduce water truck traffic on CR 204 and 211. The initial project traffic plan is continuously being modified to reduce overall traffic on County roads. The proposed pipeline would significantly reduce water truck traffic (water balance is still being refined). en 0 Washington Group International 1111110 Integrated Engineering, Construction, and Management Solutions PICEANCE BASIN NON -CONVENTIONAL GAS PROJECT EARLY PRODUCTION SYSTEM GARFIELD COUNTY SPECIAL USE PERMIT APPLICATION TEMPORARY OFFICE FACILITY 1 Incorporation of Editorial Review SMC 4/30/07 0 Issued for County Submitral 4/25/07 REV.

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 I). 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 Temporary Office facility. The facility will be located in the SE t/ SE 1/4 of Section 9 and in the SWl/a SWt/a of Section 10, Township 6 South, Range 98 West of the 6th Principal Meridian (see Maps - Figure 2). Chevron North American Exploration and Production Company Temporary Orrice Special Lrse Permit Piceance Basin Non -Conventional Gas Project 29021-003 1 Document No: 018-31-14-01 1.1 Location The proposed facilities will be located at the end of County Road (CR) 211 in the Clear Creek drainage (see Maps - 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, Colorado, is also known as Roan Creek Road/Drive and CR 204. The intersection of CR 211 and CR 204 is located about 12,5 miles north northwest of De Beque. Traveling north of the intersection about 4.5 miles, one reaches the end of CR 211, where a gated fence is encountered. An existing ranch road continues north onto Chevron fee land. The location is locally known as Hiner Gate and the Temporary Office area would be located just inside the gate on about 2.19 acres of land along the west side of the access road (see Maps - Figure 2). 1.2 Temporary Office Purpose Office facilities are required for planning and coordination of on-site operations, centralized emergency response capabilities, and general site security. On-site facilities are needed because of the remote location of these operations. Limited facilities in De Beque are not suitable for these operations and would require significant use of County Roads 204 and 211. Alternative nearby facilities (e.g., Parachute or Grand Junction, Colorado) would require additional commuting time, which would result in increased local traffic. The facilities will be used by CNAEP personnel until permanent office facilities are completed at another location (south of Hiner Gate). Current estimates are for the permanent facility to be completed within a year but schedule modifications may affect that timetable and require a permit extension for the Temporary Office facilities. 1.3 Hours of Operation Normal operations at the Temporary Office facility will be a 12 -hour shift, 7 days a week. Operations may be expanded up to 24-hour shifts during critical operations and emergencies. Typical usage will be transient in nature with potentially 20 individuals using the facility, but the majority of personnel would be in the field supervising site operations. Special meetings for project coordination, safety meetings, etc., could result in temporary increases in this number, but this type of use would be limited in duration (e.g., one to two hours). 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 and storrn-water controls. Once the site preparation is complete, trailer deliveries and the associated installation crews will generate short term traffic. Additional deliveries / installations will be required for the trailer foundations, water storage and sewage collection tanks, dumpster, generator, fuel tanks, communications trailer (communication tower already on site), and miscellaneous trailer furnishings. Chevron North American Exploration and Production Company Temporary Office Special Use Permit Piceance Basin Non -Conventional Gas Project 29021-003 2 Document No: 018-31-14-01 Because the Hiner Gate is the access control point for the majority of the drilling operations, numerous vehicles will check in at this location daily. An estimated 150 to 500 daily vehicle round trips will be required initially to support drilling and construction operations for the site. About 10- to 15 -percent of these vehicles will service operations south of Hiner Gate but the majority will be checked in and out at the Ternporary Office. Vehicles will range from heavy duty pickup trucks to oversized vehicles for transporting the drilling rig and associated equipment. The majority of the traffic will be sized to meet posted weight restrictions but a number of heavy and wide loads will be required to place major equipment (e.g., drilling rigs, compressors, etc.). The EPS Plan of Development discusses the types of operations that will require vehicle support. Up to 20 vehicles will be directly associated with supervisory personnel who will use the Temporary Office during their normal shift. These vehicles will be used to travel to the various field locations and for accessing the site. Additional traffic passing through the Temporary Office checkpoint will include the drilling rig crews. Each drill rig will have a five person operational crew who will travel between the well pad and the Central Man Camp located about one -mile northeast of the intersection of CR 204 and CR 211. Current plans are to minimize drill crew traffic by limiting each crew to one on-site vehicle. Personnel also making use of the Temporary Office will include individuals from the operation specific man camps maintained at each drilling pad. Each drilling pad camp will house about 15 to 20 specialists including drill site managers, rig managers, mud engineers, safety officers, directional drilling experts, measurement while drilling instrumentation engineers, and solids control personnel. These individuals also will operate on 12 -hour shifts but will primarily remain at the pad camp. Members of these crews will occasionally make use of the Temporary Office facilities and / or pass through the checkpoint for a variety of reasons. A combination of company and personal vehicles will be located at the pad camps to provide access to other on-site activities and to allow crew members to travel off-site for groceries, entertainment, etc. Carpooling will be encouraged to minimize the number of personal vehicles traveling off site. Additional traffic associated with the Temporary Man Camp will include subcontractors servicing the potable water and wastewater systems, supplying bottled water, and providing trash collection. The number of trips required for these services will be dependent on the company selected and the capacity of their service fleet. 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. 1.5 Civil Specifications / Regulatory Requirements The office area will be graded and then prepared with four inches of 3/4 -inch gravel. A 20 - vehicle parking area will be provided east of the trailers for crewmember vehicles. A grading permit will be submitted to Garfield County at the completion of the final civil design. Chevron North American Exploration and Production Company Piceance Basin Non -Conventional Gas Project 29021-003 3 Temporary Office Special Use Permit Document No: 018-31-1a-01 The area will be graded as specified in Drawing 018-12-1 1-1 1 1-01 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 associated Construction Storm Water Permit). An addendum to the SWPPP for specific storm water controls for this site is provided in Drawing 018-12-1 1-061-001 (see Erosion Control Drawings). 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 the eventual site reclamation in accordance with specific SWPPP requirements. Seed mixes used for site stabilization and revegetation will be in compliance with Garfield County Reclamation Standards. The stockpile will be monitored and controlled for noxious weeds throughout the operation of the Temporary Office. General information concerning the area reclamation plan for the area is provided in Section 8.4. Upon completion of the final grading the Temporary Office area will be prepared with four inches of 3/4 -inch gravel. A 20 -vehicle parking area will be provided south of the office buildings for crewmember vehicles. A site wide construction dewatering permit is currently being obtained from the Colorado Department of Public Health and Environinent (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 Specifications / Regulatory Requirements Four vendors are currently being evaluated for supplying the manufactured office buildings. The companies currently under consideration include Mod Space (GE Modular Space), Mobile Mini, Pac-Van, and Williams Scotsman. Four 12 -ft x 60 -ft manufactured offices (or equivalent) from one of these vendors will be located at the Temporary Office site. The trailers will contain a combination of private offices, multi -person operations centers, and meeting rooms (general site plans and floor plans provided in Building Information attachment). Each trailer will provide restroom facilities and a limited kitchen and be equipped with individual electric heat and air conditioning tied into the site central power system. A Williams Scottsman 32 -ft x 10 -ft manufactured office will be located along the access road at the Temporary Office location (see attached Drawing 018-12-1 1- 1 1 1-001). The building will serve as the security access facility for the site. All traffic proceeding past the Hiner Gate access point will check in and out through this facility. The building contains an office and a meeting area with some limited storage (see Building Information attachment). A 30 -ft communication tower is to be located at the southern end of the Temporary Office site (special use permit under review). This tower along with four additional towers is necessary to provide radio and cellular communications in the deep canyons. All of the towers meet Federal Communications Commission and National, Federal Aviation Administration, International Fire Code, and National Electrical Code regulations. An 8 ft x 9 ft modular communication system trailer also is located on the site. This building provides shelter for on-site Supervisory Control and Data Acquisition (SCADA) instrumentation and general site communications. Vendors including Dupont Buildings, JoaQuin, Shelterworks, and Thermohond are currently being evaluated (see Building Information attachment). All Chevron North American Exploration and Production Company Temporary Office Special Use Peril it Piceance Basin Non -Conventional Gas Project 29021-003 4 Document No: 018-31-14-01 communications equipment installed in the building will meet Federal Communications Commission, International Fire Code, and National Electrical Code regulations. A fuel depot will be installed at the Temporary Office to service on site vehicles. The depot will consist of two 1,000 -gallon aboveground Convault tanks, one for diesel fuel and one for unleaded gasoline. These tanks have integral secondary containment and are reinforced with concrete walls. Detailed specifications are provided in the Fuel Depot attachment. Information about these tanks will be incorporated into the site Spill Prevention Control and Countermeasures (SPCC) Plan (see attached SPCC Plan) during the next review cycle (October, 2007). The tank installations shall be in accordance with manufacturer and SPCC plan specifications, local fire codes, National Fire Protection Association requirements, and International Fire Code. 1.7 Electrical Utilities / Regulatory Requirements Electrical power will be provided to the site through a combination of existing service and supplemental power generation. The existing power is a 500 kVA, single phase, 12,000 volt line provided by Grand Valley Power. Because of variations in Temporary Office power requirements and additional operations that will be fed from this line, a 1,000 kW supplemental / backup gas-fired generator will be installed at the site. The gas will be provided by the installation of a two-inch line connected to the existing flex -line, 1 3 -delineation well gathering line. The connection will be switched to the eight -inch valley gathering line when that pipeline goes into service. The specific generator vendor is still under review, with an anticipated selection by mid-May. Unit details will be provided to the County as they become available. Air permits also will be submitted as soon as the final selection is made. Copies of the appropriate permits will be provided to Garfield County in a supplement to this permit application. The generator will be equipped with an appropriate muffler or sound suppression system to meet the 50 to 55 db(A) requirements for rural installations A study is currently underway to determine needed electrical service improvements for the area. An initial upgrade will provide up to 5 MW, with ultimate plans to upgrade to 240 MW service. Study results are anticipated to be completed by mid year. 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 Temporary Office area is not located in the floodplain. 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 material that may be encountered. Chevron North American Exploration and Production Company Temporary Office Special Use Permit Piceance Basin Non -Conventional Gas Project 29021-003 5 Document No: 018-31-14-01 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 Each building will be provided with at least two Class ABC fire extinguishers and all personnel will be trained in their proper operation. The communication building will be provided with one Class C, carbon dioxide electrical fire extinguisher and a general Class ABC extinguisher. Cooking will be primarily limited to kitchens at the Man Camps but there may be occasional outdoor cooking for motivational events or group meetings. An enclosed gas grill, equipped with a general Class ABC extinguisher, will be used for these events. The grill will be positioned on the gravel pad at least 25 ft from any vegetation. No outdoor cooking or fires will be permitted during State or County fire bans. 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. The Temporary Office buildings potentially could be used as emergency shelter in the event of a significant weather event. Occupancy would be limited to the time necessary to open the roads. CNAEP has contracted with Hyland Enterprises, Inc. (see attached Hyland Contract) to supplement the County maintenance operations (scheduled hours 5 am toy pm) but there is still a possibility of road closures. Worst case storms in the area have shut down area roads for up to 72 hours. A number of options are being explored to minimize the possibility of stranding personnel at the site. Possible contingency plans include a 5 to 10 day water, food, and fuel supply maintained at any facility where personnel could become stranded. A detailed "stranded Chevron North American Exploration and Production Company Temporary Office Special Use Permit Piceance Basin Non -Conventional Gas Project 29021-003 6 Document No: 018-31-14-01 scenario" will be developed prior to the October, 2007, and be incorporated into an updated Emergency Response Plan. 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 permit and any other legal water supply information, including a water allotment contract or an approved water augmentation plan to demonstrate that you have legal and adequate water for the proposed use. CNAEP is currently performing an internal audit of two local water / wastewater service providers to determine their operations meet all of the company requirements, including the required permits. Down Valley Septic and Mountain West Oil Field Service & Supplies (Mountain West) are being evaluated to determine if they meet CNAEP contract standards. The intention is to have one vendor service all on-site facilities. 2.1 Water Supply System The Temporary Office will rely on a water storage tank that will be provided by either Mountain West or Down Valley Septic. Average residential usage is typically listed as 50 to 100 gallons per day, but usage at an office facility is typically Tess. Assuming a worst case for water usage the system will need to be sized for up to 1,000 gallons per day. Both vendors have indicated that actual use is dependent on the individual occupants, A water augmentation plan study as required by the permitting process has been initiated in preparation for the permanent office location. The water augmentation plan may encounter some resistance because Clear Creek is an over -appropriated basin. Specific information about the water system is provided in Section 8. 2.2 Wastewater Management System The wastewater management system for the Temporary Office will be provided by an on-site tank provided by Mountain West or Down Valley Septic. Both vendors indicated that the insulated collection tanks would be located above ground with a general size of 5,000- to 8,000 -gallons. The actual service schedule for the tanks will be dependent on the vendor truck size and the general site usage. Portable toilets will be provided at the security trailer because of the transient nature of personnel passing through the gate. These units will be serviced at least twice a week by the selected vendor. Specific information about the wastewater system is provided in Section 8. 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 Chevron North American Exploration and Production Company Temporary Office Special Use Permit Piceance Basin Non -Conventional Gas Project 29021-003 7 Document No: 018-31-14-01 (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 018-12-1 1- 11 1-01 sheet 1 (see attached Drawings). 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. The topographic vicinity neap 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.

(2) Street improvements adequate to accommodate traffic volume generated by the proposed use and to provide safe, convenient access to the use shall either be in place or shall be constructed in conjunction with the proposed use; (3) Design of the proposed use is organized to minimize impact on and from adjacent uses of land through installation of screen fences or landscape materials on the periphery of the lot and by location of intensively utilized areas, access points, lighting and signs in such a manner as to protect established neighborhood character; 8.1 Water and Sanitation Service 8.1.1 Water Supply System As discussed in Section 2, CNAEP is currently evaluating two local service vendors (Down Valley Septic and Mountain West) with the intention is to have one vendor service all on-site facilities. Both vendors have indicated that the Temporary Officde probably will be supplied using 2,400 - gallon tanker trucks. Vendor service trips will be determined by the on-site tank capacity and facility usage, with up to daily service required. Servicing all of the on-site facilities potentially will require multiple trips each day. The selected vendor will maintain records of water testing (coliform bacteria), both source and on-site, and provide copies to CNAEP. Any tests indicating the presence of bacteria will be reported to the Garfield County Board of Health or designee. A 2,000- to 8,000 -gallon, aboveground, insulated, potable water tank will be supplied by the selected vendor will be installed north of the office trailers (see Drawing 018-12-1 1-1 1 1-001). Tank and installation specifications will be provided as soon as the vendor is selected. The tank will be protected with pipe/concrete barriers to minimize accidental damage from vehicle traffic. 8.1.2 Wastewater Management System The CNAEP internal audit of Down Valley Septic and Mountain West Oil Field Service & Supplies also is evaluating their ability to provide sewage service to the Temporary Office (and other facilities). The intention is to have one vendor service all on-site facilities. Both vendors have indicated that the Temporary Office will be serviced using 2,400 -gallon tanker trucks. Current estimates are for a minimum of two service trips a week, but actual usage may vary depending on the number of people manning the office. A 2,000- to 5,000 -gallon, aboveground, sewage tank will be supplied by the selected vendor will be installed north of the office trailers (see Drawing 018-12-11-111-001). Tank and installation specifications will be provided as soon as the vendor is selected. The tank will be protected with pipe/concrete barriers to minimize accidental damage from vehicle traffic. Current plans are to move these operations to a permanent Office / Shop / Warehouse / Laydown Yard location, which will have a permitted water well and engineered sewage treatment system. Chevron North American Exploration and Production Company Temporary Office Special Use Permit Piceance Basin Non -Conventional Gas Project 29021-003 9 Document No: 018-31-14-01 Site selection and the construction schedule are still in the study phase. This site will be included in a water augmentation plan that is currently under study. 8.1.3 Sanitation Services The Temporary Office area will be maintained in a clean, safe, and sanitary condition, free of weeds or refuse. Down Valley Septic or Mountain West will provide trash collection services for the Central Man Camp. One 6- to 30 -cubic yard, "bear -proof" dumpster (dependent on the vendor) will be provided on site to manage miscellaneous solid waste. The duinpster will be constructed of steel and include dual steel lids. The container lid will be secured using a steel bar across the top of the lid with positive connection and a hasp lock at the sidewalls to restrict entry (or equivalent). Site personnel will be informed of the proper closure procedures. No hazardous materials will be disposed of in this container (posted accordingly). Sufficient signage, in multiple languages if required, will be posted to ensure that all users are aware of the appropriate regulations/procedures. 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). Another transportation issue associated with shipments along the I-70 corridor is the closure of the eastbound lanes at the Hanging Lake Tunnel near Glenwood Springs due to a crack in the tunnel ceiling. All traffic through this section of I-70 will be routed through the westbound lane. 8.3 Visual Effects The Temporary Office facilities are located in a remote region of Garfield County, with visual effects mostly limited to an adjoining lessee. Visual effects include the physical presence of the facility, building lighting, and operational traffic. Outdoor lighting will be positioned downward to minimize impacts on the lessee. Additional mitigation measures identified by the CNAEP ESHIA process will be implemented as determined by project management. Chevron North American Exploration and Production Company Temporary Oftice Special Use Permit Piceance Basin Yon -Conventional Gas Project 29021-003 10 Document No: 018-31-14-01 8.4 Reclamation and Revegetation Plan Current planning specifies that when the permanent office location becomes available, all operations, with the exception of the communication tower and building, will be moved to the new site. Once the trailers and equipment are moved the gravel pad will be excavated and the area will be re -graded and planted with native vegetation. Reclamation and revegetation activities will be in accordance with requirements outlined in Garfield County Zoning Resolution 5.02.21 (11). General details of the re -vegetation activities are provided in the IVNWM Plan and Storm Water Pollution Prevention Plan (SWPPP) and will be included in the final revegetation plan. 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:f/www.garfiieldcounty.com/building_and_planning/index.htm, or information can be obtained from this office. Because the Temporary Office 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. Conner and Barbara J. Davenport, .lune 3, 2005).and a Biological Survey (WestWater Engineering, July 11, 2006) were performed as part of the permitting process for an 8 -inch gathering pipeline that will be part of the EPS. These studies provide baseline information for the ESHIA process and have been considered during the design process. Copies are provided as attachments for reference purposes. 9.2 Supplemental Industrial Operations Requirements A preliminary impact statement of the EPS, which includes the Temporary Office facilities, is provided as the EPS Preliminary Plan of Development that was submitted with this permit. Specific applicable statements are as follows: No water will be removed or discharged from any of the State's waters without applicable permits. Any discharge will meet the drinking water standards controlled by the Colorado Department of Health and Environment. The generator for the Temporary Office will be provided with the appropriate snuffler or sound suppression system to meet the 50 to 55 db(A) requirements for rural installations. Dust Chevron North American Exploration and Production Company Temporary [)flicc Special Use Permit Piceance Basin Non -Conventional rias Project 29031-003 I I Document No: 01S-31-14-01 generated by vehicle traffic will be controlled with adequate water trucks and the addition of gravel to CR 211. The man camp facility will not generate vapor, dust, smoke, glare, excessive noise, vibration, or other emanations. Vehicle traffic to and from the man camp will have effects on wildlife but the ESHIA process will be used to identify problem areas and determine mitigation options. Mitigation recommendations will be provided to project management, who will evaluate the alternatives and implement appropriate measures. A bond for the site reclamation after the cessation of activities will be provided as an addendum to this application upon determination of the total site disturbance. 9.3 Supplemental Industrial Performance Standards All operations will comply with applicable County, State, and Federal regulations for water, air and noise pollution and shall not be conducted in a mariner constituting a public nuisance or hazard. Specific information about noise, heat, dust, etc. is provided in Sections I through 8. An air emissions permit will be obtained for the proposed gas -powered generator when the final selection process is completed. The fuel depot (two 1,000 gallon fuel tanks) installation will comply with the Oil Pollution Prevention regulations (40 CFR 1 12) of the Clean Water Act, National Fire Prevention Association guidance, and International Fire Code regulations. A copy of the site SPCC plan will be provided to the De Beque fire chief for review. No outdoor storage, including heavy equipment, will be allowed at the Temporary Office location. All storage will be maintained at the service pads until the Office / Shop / Warehouse / Laydown Yard area is constructed. No repair operations will be allowed at the Temporary Office location. All repairs will be completed at the drilling or service pads. Loading / unloading operations will include use of the fuel depot (fuel delivery and filling individual vehicles), water deliveries, sewage removal and trash removal. Fueling operations are strictly controlled by the requirements listed in the SPCC plan. The fuel depot tanks will have integral secondary containment in accordance with 40 CFR 122. The integrity of the secondary containment will be monitored as part of normal SPCC plan inspections. The use of water and sewage storage tanks currently eliminates the need for percolation tests or ground -water resource tests. 9.4 Supplemental Regulation for Accessory Dwelling Units While the Temporary Office facilities will not be continuously manned, the following Garfield County requirements are applicable. Outdoor food storage is prohibited to prevent the attraction of animals to the Temporary Office facility. Chevron North American Exploration and Production Company Temporary Office Special Use Permit Piceance Basin Non -Conventional Gas Project 29021-003 12 Document No: 018-31-14-01 All facilities will be permitted in accordance with the Garfield County Building Permit.

This SWMP is intended to be periodically updated as needed to address planned developments, new disturbances, and other changes needed to manage storm water and protect surface water quality. 1.1 Storm Water Runoff Permitting Requirements The Federal Clean Water Act [Section 402(p)] requires that discharges of pollutants to waters of the United Station from any point source be regulated by NPDES permits. In November 1990 the USEPA published final regulations that established application requirements for storm water associated with construction activity for soil disturbances of 5 acres or more be rcgulatcd as an industrial activity and covered by an NPDES permit. In December 1999 the USEPA published final Phase ❑ NPDES regulations that estab€ishcd application rcquircmcnts for storm water associated with construction activity for soil disturbances to be regulated as an industrial activity and covered by an NPDES permit. These regulations became effective July 1, 2002. Construction permits are required for oil & gas activities that disturb 5 or more acres during thc life of the project or arc part of a larger common plan of development. CDPHE considers a common plan of oil and gas development to mean development of several well pads and/or related infrastructure in a contiguous arca either during thc same timc period or under a consistent plan for long-term development. 3 SKINNER RIDGE SWMP CHEVRON U.S.A., INC 1.2 Project Description and Background The Skinner Ridge Common Plan of Dcvclopmcnt will be located in Garfield County. Colorado within Townships 5 & 6 South, Range 98 West. The town of Dcbcquc, Colorado is the nearest population center. The Skinner Ridge arca is located approximately 14 miles north of DeBequc. The current drilling and dcvclopmcnt plan includes pad construction, access road improvement/construction, pit construction, installation of associated facilities, well drilling, well completion, well testing and pipeline construction. The area of disturbance including the natural gas well pads, the access roads and gathering system pipclinc 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. 1 1 111 S. Wilcrest Houston, Texas 77099 Ph (981) 561-4991 The Chevron contact person for thc project is Scan Norris. Mr. Norris can be contacted by phone at (970) 270-75[7. Chevron will be in charge of all aspects of this project. Contractor(s) will do the actual construction and grading but all work will be supervised by Chevron and all decisions will be made by Chevron. 4 SKINNER RIDGE SWMP CHEVRON U.S.A., INC 2.0 CONSTRUCTION SITE DESCRIPTION 2.1 Site Location and Construction Area Description The Skinner Ridge project arca will be located in Garfield County. Colorado within Townships 5 & 6 South, Range 98 West. Thc following is a list of the sections that arc in the dcvclopmcnt 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 constriction. soil materials will be managed so that erosion and sediment transport arc 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. Thc development consists of the construction of roads, pipelines, drilling pads and gas treatment facilities. The construction of the facilities in the dcvclopmcnt arca will be done using conventional cut and fill, trenching and earth moving techniques. Reclamation and final stabilization will be conducted as described in Section 7. 2.2 Schedule of Construction Activities Natural gas exploration and dcvclopmcnt 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 the natura] gas resource and construction of necessary improvements on this property will likely continue for thc 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/Complction), the second phase is the Production (Operation/Maintenance), and thc third phase k the Abandonment and final reclamation. Each work phasc is briefly discussed below. 5 SKINNER RIDGE SWMP CHEVRON U.S.A., INC Development (Construction/Drilling/Completion/Reclamation) The development phase includes the following activities; pad construction. well drilling, well completion, gas lint installation, and pad arca reclamation. Pad reclamation is accomplished by backfilling the reserve pit. contouring disturbed soils to conform with the surrounding terrain, replacing the stockpiled top soil, seeding of disturbed soil areas in order to reestablish a cover vcgctation, and construction of erosion and scdimcnt control structures. The completion of a well {gas production) generally triggers a one- year timc period in which thc reclamation phase of work should be completed. For the specific final stabilization seed mixture plcasc rcfcr to the Figure 2. Production (Operation/Maintenance) The production phase includes the operation and maintcnancc activities during natural gas production. The typical cquipmcnt on a pad during the production phasc consists of a wellhead, a separation unit, from one to several 300 -barrel capacity aboveground tanks for condensate, and an above ground tank for storing produced water. Gas pipelines are also installed during this phase of work. Reclamation activities during this phase include maintcnancc of rcvegetated areas and maintcnancc of the erosion and sediment control structures. Natural gas wells in the Skinner Ridge arca arc projected to produce 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 be plugged, capped, and all surface equipment will be rcmovcd. Subsurface pipelines will be removed to specified locations and plugged. Thc pad arca will be reclaimed by contouring disturbed soils to conform to the surrounding terrain, by replacing the stockpiled top soil, by sccding of disturbed soil areas in order to reestablish cover vcgctation, and by construction of erosion and sediment control structures as needed. If thc exploratory holes yield economically viable natural gas resources; additional gas well drilling will proceed. Any additional wells will need to be added to the SWMP. Once the welt is completed and brought into production it will operate as an unmanned facility twenty-four hours per day, seven days per week, and 365 day a year. Chevron personnel or contract personnel will visit the site daily or at a minimum one per week. Once stabilization is achieved, defined as uniform vegetative cover established with a density of at least 70 percent of pre -disturbance levels. a well pad may he rcmovcd from this SWMP for sediment controls. However. if petroleum hydrocarbons or other chemicals impact stormwatcr as a result of industrial activities onsite, the impacted stormwatcr will be addressed by following a spill prevention control and countermeasures (SPCC) plan. 6 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 side 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 dccp and well drained.

The most common source of pollution from pad and access road construction is scdimcnt. which can be carried away from the work sitc 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 constriction activities to power or lubricate cquipmcnt and include: fuel, gear oil, hydraulic oil, brake fluid, and grease. Debris from laydown areas, rcsiduc from cquipmcnt cleaning and maintenance, and solid waste generated from land clearing operations and human activity (trees, brush. paper, trash. ete.) present other potential pollution sources within the construction site. Spills or teaks from potential sources are described in the SPCC plan. Response to certain events may require specialized training due to health and safety concerns. 11 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 thc use of structural and/or nonstructural controls. This section describes erosion and scdimcnt controls to be used at active construction sites to minimize possible sediment impacts to storm water runoff. The proposed erosion control features can include: • Placement of any topsoil stockpiles along the cut -slope side of the pad to divert run-on; • Installation of silt fence, straw bales or diversion ditches at or below thc toe of fill slopes where located within 100 feet of surface water drainages or where steep slopes will likely result in rapid drainage from the location to nearby drainages, and; • Installation of check dams in areas of concentrated flow; • Use of erosion control matting, rock armoring, and soil berms to prevent soil erosion. 4.1.1 Uphill topsoil stockpile/diversion berm In order to divert surface runoff from upgradicnl areas away from construction areas. salvaged topsoil may be placed on the uphill side of the road cut slope. The topsoil stockpile may be placed and graded to form a diversion berm that will direct surface water away from the road. 4.1.2 Downhill silt fence Silt fcncc can be installed at the down gradient edge of the road and other fill slopes located within 100 feet of a surface drainage. Silt fences may also be required in areas where steep slopes will likely result in fast flow of water from the location to nearby drainages. Typical silt fence installation details arc given in Appendix B, 4.1.3 Hay bale check dams Hay bale check dams should be installed al suitable locations to slow thc concentrated flow of drainage water. Typical hay bale check dam installation details arc given in Appendix B. 9 CHEVRON U.S.A. INC SKINNER RIDGE SWMP CHEVRON U.S.A..

Gasoline and diesel fuel will be stored in portable storage tanks with secondary containment. Lubricant. hydraulic. and miscellaneous oils and solvents will be stored in 55 -gallon or smaller containers. Pollutants from petroleum products used during construction activities adhere easily to soil particles and other surfaces. In case of a spill or leak, soils contaminated with petroleum products will be contained and removed to a proper disposal site. Proposed soil erosion and sediment control practices will aid in retention of spills or leaks. Usc of secondary containment and drip pans will reduce the likelihood of spills or Teaks contacting the ground. Proposed maintenance and safe storage practices will reduce the chance of petroleum products contaminating the road site. Oily wastes such as crankcase oil, cans. rags, and paper containing oils will bc placed in proper receptacles and disposed of or recycled. An additional source of petroleum contamination is Icaks from cquipmcnt and vehicles. Routine daily inspections will be conducted to identify Icaks and initiate corrective actions, if needed. The following guidelines for storing petroleum products will be used. • All product containers will be clearly labeled. • Drums will be kept off the ground within 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 accordancc with applicable regulations. • Storage areas and containers will be regularly monitored for leaks and repaired or replaced as necessary. Workers should be reminded about proper storage and handling of materials during weekly subcontractor or safety meetings Other Chemicals Products Management Additional materials will be used and stored on site for use in construction. These materials will be stored appropriately and managed to minimizc spills and leaks. Storage areas will be regularly inspected and any minor spills or Teaks will be cleaned up i mmcdiatcly_ Materials Management 14 SKINNER RIDGE SWMP CHEVRON U.S.A.. INC The construction contractor will maintain a laydown or staging area for equipment and materials storage on site. These areas will be maintained with good housekeeping and will he inspected on a regular basis for spills, Icaks, and potential contamination. 433 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 watcr runoff. Routine maintcnancc will be limited to fueling and lubrication of equipment, Drip pans will be used during routine fueling and maintcnancc 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 bc 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 CHEVRON U.S.A., INC SKINNER RIDGE SWMP CHEVRON U.S.A., INC SKINNER RIDGE SWMP 5.0 INSPECTION AND MAINTENANCE PROCEDURES SKINNER RIDGE SWMP CHEVRON U.S.A., INC 6.0 NON-STORMWATER DISCHARGES No non -storm water discharges arc anticipated from the project.

INC 7.0 FINAL STABILIZATION Areas which have been disturbed are considered to be stabilized when a uniform vegetative cover with a density of 70 percent of thc 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. Areas at which arc not used for facilities. access roads, materials storage yards. or other work areas will be stabilized with vegetation. Areas that arc stabilized with vcgctation will bc considered to have achieved final stabilization when a uniform stand of vegetation with a density of at least 70 percent of the pre -disturbance has been established. Other areas which may include facilities, access roads, materials storage yards, and other work arcas will be stabilized with thc use of permanent. physical crosion reduction methods which include. but arc 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 stricture that inhibits contact of precipitation with the soil surface which is generally considered to be placement of a stricture (building or tank) over the soil surface. 3. Gravel surfacing — gravel surfacing will bc applied in areas such as access roads, materials storage yards, and other work surfaces. Some gravel may be lost duc to erosion from intense precipitation events or duc to vehicle traffic. Gravel surfaces will be periodically inspected to determine the need for gravel replacement. Gravel surfaces will bc replaced or repaired (through grading) when inspection reveals that thc gravel surface is no longer effectively covering the soil surface. l9 SKINNER RIDGE SWMP CHEVRON U.S.A., INC 8.0 CERTIFICATIONS 8.1 Owner/Applicant Certification I certify under penalty of law that this document and all attachments were prepared under my direction or supervision in accordance with a system designed to assure that qualified personnel properly gather and evaluate the information submitted.

CONTENTS OF THE STORMWATER MANAGEMENT PLAN (cont.) C. b) Materials Handling and Spill Prevention. The SWMP shall identify any procedures or significant materials (see definitions at Part LD.) handled at the site that could contribute pollutants to runoff. These could include sources such as: exposed storage of building materials, fertilizers or chemicals; waste piles; and equipment maintenance or fueling procedures. Areas or procedures where potential spills can occur shall have spill prevention and respoose procedures identified. Measures to control stormwater pollution frons dedicated concrete batch plants or dedicated asphalt batch plants coveted by this certification, must be identified in the SWMP. 4. Final Stabilization and Longterm Stormwater Management The plan shall include a description of the measures used to achieve final stabilization and measures to control pollutants in stormwater discharges that will occur after construction operations have been completed. Final stabilization is reached when all soil disturbing activities at the site have been completed, and uniform vegetative cover has been established with a density of at least 70 percent of pte-distur'bance levels, or equivalent permanent, physical erosion reduction methods have been employed. For purposes of this permit, establishment of a vegetative cover capable of providing erosion control equivalent to pre- existing conditions at the site can be considered final stabilization. The permittee will be responsible for providing to thc Division the documentation to make this comparison. The Division may, after consultation with thc permitte a and upon good cause, amend the final stabilization criteria for specific operations. 5. Other Controls The plan shall include a description of other measures to control pollutants in stormwater discharges, including plans for waste disposal and limiting off -side soil tracking. 6.

The forms discussed in die Rationale and Perth are available on tie Division's website at: hap://www. cdphe state. ca.as/wg/penwiawri4wgedpmtktml A. Changes in this General Permit Several notable changes from the previous Genera! Permit for Consrrmelon Activities kave been incorporated into this permit. Most of the changes are related to the Phase ll revision to the stormwater regulation in the Catorado Discharge Permit System Regulations (5CCR 1002-61), effective March 2, 2001. Significant changes are listed below: 1. Permit coverage is naw requiredfor consauction sites that disturb 1 to 5 acres (i.e., viral construction activities). Allowances have been made for small construction activities to comply with the requirements of a Division -approved QualEying Local Program (refer to section VI below for a discussion ofQuafiTying Local Programs) in place of many specifee requirements in the Permit, including requirements to submit an application, inactivation notice. and fees to the Division. Refer to Part 1.A.3 of the Permit and section VILA of the Rationale for more details. 2. The requirements to submit with the application the Township, Range, section and quarter section of a sae and a list of any 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 front the star 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. If permit coverage beyond the expiration date is needed (i.e., the site has not been finally =butted), the permittee must submit an extension request form to the Division at least 10 days prior to the expiration. COLORADO DEPARTMENT OF PUBLICHEALTHAND ENVIRONMENT, Water Quality Control Division Rationale - Page 2. Permit No. COR -030000 L INTRODUCTION (cont) 4. The Rationale discussion on the Exemptions for Small Municipalities (Section 11.5) has been changed to include the March 10, 2003 deadline for permit coverage for municipally -owned industries. This did not invasive any changes to the permit. II. BACKGROUND As required under the Clean Water Act amendments of 1987, the Environmental 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 ofNPDES). The Water Quality Control Division ("the Division) has stormwaier regulations (5CCR 1002-61) in place. These regulations require specific types of industrial facilities that discharge stornnvarer associated with industrial activity (industrial stormwater), to obtain a CDPS permit for such discharge. The regulations specifically include construction activides thal disturb one acre of land or more as industrial facilities. Construction activities that are pan ofa larger common plan of development which disturb one acre or more over a period of time are also included. A. General Permits 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 This permit does not require submission of effluent monitoring data in the permit application or in the permit itself. 11 is believed that a fully implemented Stormwater Management Plan (SWMP) should be sufficient to control water quality impacts. The permit requires dischargers to control and eliminate the sources of pollutants in Stormwater through the development and implementation of a SWMP. The plan must include Best Management Practicer (BMPs), which will include pollution prevention and source redaction measures. This will constitute BAT and BCT and should achieve compliance with water quality standards. The narrative permit requirements include prohibitions against discharges of non-stornneoter (e.g., process water). Refer to Pan LC.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 Qaaliry Control Act. Failure to submit the required fee when due and payable is a violation of the permit and will result in enforcement action as discussed below. Permtaees will be billed for the initial permit fee within a few weeks of permit 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 Qualifying Local Program may not be required to submit an application for coverage or a notice of inactivation and may not be required to pay the annual fee. Refer to Section VILA of the Rationale for further information. C. Vialations/Pe allies Dischargers ofstormwater associated with industrial activity, as defined in the Regulations for the Stale 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 storntwater, 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 CDPSpermit requirement constitutes a violation. Civil penalties for violations of the Act or CDPS permit requirements may be cry to $10,000 per day. Criminal pollution of state waters is punishable by fetes of up 10 525,000 per day.

STORMWATER DISCHARGES ASSOCIATED WITH CONSTRUCTION ACTIVITY The Ston iwater 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 specifically included is the listed industrial activities. A. Construction Activity Constratdon activity inebedes clearing, grading and excavation activities. Construction does not include routine maintenance performed by public agencies, or their agents to maintain anginal line and grade, hydraulic capacity, or original purpose of the facility. Definitions of additional terms can be found in Part LD of the Permit. Starmwater 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 part 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 crosiracifoe activities may be taking place at different times on different schedules under one plan. B. Types of Activities Covered This permit is intended to cower most new or existing discharges composed entirely ofstonnwaterfrom construction activities that are required by State regulation to obtain a permit. This includes stormwater discharges associated with areas that are dedicated to producing earthen materials, such as soils, sand. and gravel. for use at a single construction site. These areas may be located at the construction sae or at some other location. This permit does not authorize the discharge of mine water or process water from such areas. This permit also includes stonnwater discharges associated with dedicated asphalt plants and concrete plants located at the construction sites. C. Times ofActivioes NOT Covered This permit does not cover stonnwater discharged from construction sites that is mixed with stormwater from other types of industrial activities. or process water ofany kind. Other types of industrial activities that require atormwater discharge permits pursuant to different sections of the regulations (Regulation 5 CCR 1002-61, Section 61.2(e)(iir)(A-1. K)], are not covered by this permit. This permit also does not cover the discharge of process water. If the construction activity encounters groundwater. a Construction Dewatering Discharge Permit (Permit Number COG -070000) must also be obtained tet order so discharge this groundwater from the excavation site. An application for this permit can be obtained from the Division at the address listed in Part LA.4a of the Permit. D. Exemptions for Small Municipalities The late -modal Surface Transportation Efficiency Act of 1991 (Section 1068(()) added an exemption to the atormwater regulations for municipalities with less than 100,000 population. The term "municipality" includes cities. fawns. counter. special districts or any entity created by or pursuant to State law. Stormwater discharges associated with construction activity for facilities or sites that are owned or operated by a small municipal&y are not required to apply for or obtain a stormwaterpermit 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 general permit, operators ofstormwater discharges associated with construction activity may be granted authorization to dischargesrormwater into waters of the State of Colorado. This includes stormwater discharges associated with industrial activity from areas that are dedicated to producing earthen materials. such as soils, sand and gravel. for use ata single construction site, and dedicated asphalt plants and dedicated concrete plants. This permit does not pre-emptor supersede the authority of local agencies to prohibit, restrict or control discharges of stormwater io storm drain systems orother water courses within iheirjurisdiction. Authorization to discharge under the permit requires submittal ofa completed application form and a certification that the SWMP is complete, unless the site is covered by a Qualifying Local Program. Upon receipt of all required information, the Division may allow or disallow coverage under the general permit. Y. APPLICATION AND CERTIFICATION At least ten days prior to the commencement of construction activities (r. e.: 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 certification dear the SWMP is complete. In order to avoidconfesion during processing, original signatures are required for the application to be considered complete. For small construction sites only, if the site is covered by a Qualifying Local Program (see below), submittal of an application is not required. For the purpose of this permit, the 'operator" is the person who has day -today 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, different types of parties may satisfy the definition of 'operator' and the certification may be transferred as roles change. _ - (Note - Under the Federal regulations, this application process 0 referred it es a Notice of Intent or NO!. For internal consistency with is current program, the Division will continue to use the term "application ) An outline of the permit application requirements is found in the permo at Part LA.4.b. Ifthis general permit is applicable, then a certification will be developed and the applicant will be certified under this general permit. VI. QUALIFYING LOCAL PROGRAMS Far stormwater discharges associated with small construction activity (i.e., one to five acre saes). the permit includes conditions that incorporate approved qualifying local erosion and sediment control program (Qualfytng Local Program) requirements by reference. A Qualifying Local Program is a municipal stormwater program for stornewater discharges associated with small construction activity that has been formally approved by the Division. The requirements -far 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 as strict as those required in this permit. A. Approval Termination: A Qualifying Local Program may be terminated by either the Division or the municipality. Upon termination of Division approval ofa QualifyingLoeal Program, any small construction activity 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 kation that the Stormwater Management Plan (SWMP) is complete as required by Pan I.A.4 of the Permit, within 30 days. B Approval Expiration: Division approval of a Qualing Local Program will expire with this general permit an 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 Qual fyi,eg Local Program.

Coverage under a Oualifvin¢ Local Program - For Small Construction Sites Only For small construction sites (disturbing less than 5 acres) covered under a Qualifying Local Program (see Section V! raring., Permit ragvirrmants appjy ataudined 12elpw The local program must have been formally designated by the Division to qualify. Most municipalities haw some type of local program and may require permits and fee.s. 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 natlfying operators and/or owners Mat they are covered by a Qualifying Laeal Program. A list ofmunicipalities with Qualifying Local Programs is also available at ht1p://www.edphestate.co.ushvq/PermitrUnit/wgadpntt.html. The Division reserves the right to require wry owner or operator within the jurisdiction of a Quabfying Local Program covered under this permit so apply for and obtain coverage under theft!! requirements of this permit. 1. Permit Coverage: Ila construction site is within the jurisdiction oja Qualifying Local Program, the operator of the toren-action activity is authorized to discharge stormwater associated with small construction activity under this general permit without the submitral of an application to the Division. Thepermirtee also is not required to submit an inactivation nonce or payment of an annual fee to the Division. 2. Permit Terms and Conditions: The pe ni#ee covered by a Qualifying Local Program must comply with the requirements of that Qualifying Local Program . In addition, the following permit sections are applicable: L 1.A.1, 1.1.2, and I.A.3: Authorization to discharge and discussion of coverage under the permit. n. 1.C. 1: General limitations that must be met in addition to local requirements. iii. LCI, LC3: Prohibition ofnonstarmwater discharges unless addressed in a separate CDPS permit, and requirements related to releases of reportable quantities. iv. ID: Additional definitions. v. Pas II (except for Pars 11.1.1, 11.8.3, II.B.B, and 11.810): Specifically includes, but is not limited to, pronsions applicable in the case of noncompliance with permit requirement, and requirements to provide information and access. B. StormwaserManasement.Plans (SWMPi) Prior to commencement of construction, a stormwater management plan (SWMP) shall 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 identtf'potential sources of pollution (including sediment) which may reasonably be expected to affect the quality of stormwater discharges associated with construction activity from the facility. In addition, the plan shall describe the best management practice MMPs) which will be used to reduce the pollutants in stormwater discharges from the construction site. Facilities mast implement the provisions of their SWMP as a condition of this permit The SWMP shall include the following trims: 1. Site Description 2. Site Map 3. BMPs for Stormwater Pollution Prevention 4. Longterm Stormwater Management S. Other Controls 4. Inspection and Maintenance 7. Signatory Requirements and Availabifiry 8. SWMP Review/Changes (See Part i.B. of the permit for a more detailed description of SWMP requirements.) COLORADO DEPARTMENT OF PUBLIC HEALTH AND ENVIRONMENT, Water Quality Control Division Rationale - Page 6. Permit No. COR -030000 Vll, TERMS AND CONDITIONS OF PERMIT (cont) C. Monitoring Sampling and resting ofstorntweterfor specific parameters is not required an 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 10 suspect that compliance with the SWMP is a problem. or to measure the effectiveness of the BMPs in removing pollutants in the effluent. D. Facility Inspections Active constriction sites must inspect their stormwater management controls at leas: every 14 days and after any precipitation or snowmel: event that causes surface erosion. At sites where construction has been completed but a vegetative cover has not been established. time inspections must occur at least once per month. *sizes where winder conditions exist, inspections 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. CS for detailed requirements of these inspections. E. Revision ofSWMP F. G. Based on the results oldie 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 soon 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. Reporting The inspection record shall be made available to the Division upon request. Regular submittal of an annual report is not required in this permit. Annual Fee The permittee 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 lune 34 billing cycle. For small construction activities. fopplieation was madefar coverage with a completion date 32 months or fess from Mg 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 are will be billed the standard annual fee. H. inactivation Notice When a site has been finally stabilized in accordance with Me SWMP, the operator of the facility shall submit an Inactivation Nadee that is signed in accordance with Part I.E.l of the permit The content of the Inactivation Notice is described in Part l.A.6 of the permit A copy of the Inactivation Notice form will be mailed to thepenniuee along with the permit certiftcatiom. Additional copies are available from the Division. An exception to the requirement to submit an inactivation has been included in the renewed permit for Small Construction Sites that will be finally stabilized within 12 months of the beginning of construction activities. In such cases, the permit certification will indicate the automatic cs7m-otioa date. Ifpenniit coverage is needed beyond that date. an extension request form must be submitted to the Division at least 10 days prior to the expiration date.

Facility: Piceance Basin Field 16 Date: January 2, 2007 Spill Prevention, Control, and Countermeasure Plan — Piceance Basin Field 1.7 Facility Layout and Diagram 1.7.1 Facility Layout • The physical layout of the facility is described as follows: The Piceance Basin Field is located in various sections of Townships 5 South, Range 98 West, of the 6th Principle Meridian in Garfield County, Colorado. The following is a list of the sections that are in the development area: Township 5 South Range 98: Sections: 8, 17, 25, 27, 36 Township 6 South Range 98: Sections: 11, 12, 22, 23, 27, 28 Figure 1 in Appendix C contains additional site location information. The town of DeBeque, CO. which lies approximately 14 miles South-southeast of the facility, is the nearest population center. The Piceance Basin Field can be reached from DeBeque by traveling approximately 14 miles north on County Road 45 In Mesa County, which changes into County Road 204 at the Garfield County line, and then traveling approximately 7 miles northwest on County Road 211. The Piceance Basin Field lies just north of County Road 211 in the Clear Creek and Tom Creek drainages. The Piceance Basin Field is an onshore production facility, owned and operated by Chevron USA, Inc. The field is located in remote high desert terrain deeply cut by the Clear and Tom Creek drainages. Vehicular travel is restricted to roadways and foot travel off roadways is difficult. The Piceance Basin Field is primarily a gas production field, but produces small amounts of condensate that are stored on site and periodically shipped to oil sales by truck. The production equipment at each Site typically includes a wellhead, a fired line heater, one or more separators, and one or two condensate/water above -ground storage tanks (ASTs). Gas is metered at each facility and is sold to a third party. The liquid condensate is sold and shipped by tanker truck. Facility Storage 140 CFR 112.7(at(31{01 Oil, as defined in 40 CFR 112.2, is stored in above -ground storage tanks (ASTs) at each well location. An inventory of the materials at the facility that are regulated under this SPCC plan is presented in the Container and Potential Spills Table in Section 2B.1. The locations of the tanks, truck loading facilities, and other potential discharge sources are shown on Figure 1 in Appendix C. The drain systems at the facilities are routed through drain lines to storage tanks or sumps. No process effluents, untreated or treated, are released off-site. Surface runoff from storm events is the only normal discharge. Facility Drainage and Distance to Navigable Waters The Piceance Basin Field lies in the south -flowing Clear Creek and Tom Creek drainages in Mid -western Colorado. Torn Creek flows into Clear Creek just south of the field and Clear Creek continues generally south and then East to its confluence with Roan Creek just south of the Roan Cliffs. The Roan Creek follows a south by southwest path to where it drains into the Colorado River.

Precipitation that may accumulate in the containment areas is normally allowed to evaporate. No automatic pumps or ejector devices are present in any of the containment areas. If removal of any water accumulated in the containment area is necessary, it will be conducted under the direct supervision of responsible personnel as described in this section. All field drainage systems (such as drainage ditches or road ditches) are inspected at regular intervals for the presence of accumulated oil that may have resulted from a small discharge. Any accumulated oil will be removed form these areas promptly upon discovery. If enough precipitation accumulates within a secondary containment area to compromise the containment capacity, the excess precipitation is removed using a vacuum truck. pump, or other appropriate method. Removed water is disposed of in accordance with applicable local, state, and federal regulations. Prior to removal of the water from any containment area, the responsible personnel visuatly inspect and test the water quality in the containment structure area and note the results in the Secondary Containment Drainage.

If so, details of inspection are provided in Section 2B.6. 2B.4.2 Flowline Maintenance Program • Describe the facility flowline maintenance program: Buried piping is coated and wrapped. When buried piping is exposed, it is inspected for deterioration. If corrosion damage is found, additional examination and corrective action will be taken. Piping which is no longer in service will be capped, valved, or otherwise restrained to prevent oil spills, Any buried equipment will be visually inspected for corrosion whenever it is exposed through excavation. All pipe supports at the facility are designed to minimize abrasion and corrosion and to allow for expansion and contraction. Pipe supports are routinely inspected as part of the general facility inspection described in Section 28.6 of this SPCC plan. Further inspection and correction will be conducted on the affected metal equipment if problems are identified to minimize the chance for a discharge from facility transfer equipment. In cases where excessive corrosion is observed, additional mitigation steps are taken and may include, but not be limited to: • Change in pipe material (fiberglass or stainless steel), • Employment of chemical corrosion inhibitors for internal corrosion, and/or • Installation of additional cathodic protection for external corrosion. 2B.5 Facility Tank Car & Tank Truck Loading/Unloading Rack(s) and Area(s) • The Facility 0 does ® does not have a tank truck loading/unloading rack.

Aboveground Storage Tanks Specifications Page 3 of 3 12.19/2006 The Aboveground Solution to the 'Inderground Problem Interest in the preservation of our environment has prompted all levels of many governments to issue strict guidelines for the installation, operation and removal of underground storage tanks (UST's). As a result, owners and operators are faced with tedious and complicated rules and paperwork. They may also be faced with expensive upgrades, purchase of monitoring equipment, testing, and obtaining pollution liability insurance to comply with these requirements. In the event of a leak, the actual costs for soil and groundwater clean-up can be catastrophic. As aboveground storage tanks (AST's) replace UST's on a more regular basis, strict guidelines are being issued for AST's as well. ConVault's innovative Protected AST's are the proven solution for these problems. Engineered for Safety ConVault Protected AST's are engineered to survive in the real world. Utilizing patented manufacturing procedures, the resulting product is a tank for flammable liquids seamlessly encapsulated in six-inch thick concrete with integral secondary containment, thermal stability, vehicle impact protection, and projectile protection. The system contains no cold joints or heat transfer points on the bottom or the sides. ''�onVault primary steel tanks (including spill containment basins) are fabricated in accordance with UL 142 (Seventh Jition). Each unit is pressure tested twice at the factory using ConVault patented processes to insure proper performance in the field. ConVault Protected AST's are shop -fabricated under strict quality controls in accordance with UL 2085 and ULC -3655 and ULC -S602 for Protected Tanks. Primary and secondary containment are independently tested at the plant in accordance with UL and ULC requirements. The ConVault Protected AST is listed in accordance with UL 2085, ULC -S655, and ULC -S602 Insulated/Secondary Containment for Aboveground Storage Tanks, Protected Type. The six-inch thick (6") concrete exterior acts as a thermal mass reducing temperature variations, provides a non -corrosive, durable exterior, and provides protection for the secondary containment. The ConVault Protected AST system has passed numerous performance tests including 2 -hour liquid - pool and furnace fire tests, vehicle impact test and projectile -resistance test. Numerous real-life events have also proven the safety of the system. The end result: owners and operators of ConVault Protected AST's are provided with PEACE OF MIND. Meets Government, _nvironmenta! and Fire Safety Regulations Each ConVault Protected AST is exhaustively production -tested at the factory before shipment to its destination. ConVault Protected AST's meet NFPA 30, 30A and 31; UFC, BOCA, SBCCI, and International Fire Code fire safety requirements and provide grounding connections in accordance with NFPA 780. ConVault Protected AST's have been approved by environmental and fire protection officials in all states of Australia, all provinces of Canada, all states of the USA, and by government officials of the Czech Republic, England, Finland, Germany, Poland, Russia, and Slovakia. The California Air Resources Board has certified ConVault Protected AST's for Phase 1 and II balanced vapor recovery, including methanol/ethanol blends. ConVault Protected AST's meet all safety requirements for primary and secondary containment, leak monitoring, spill containment and overfill protection. Specific jurisdictions may have special requirements for tank accessories. Contact your local representative for local regulations. With the first installation in 1986, over 27,000 tanks are now in service at extremely diverse locations in over 20 different countries without a single reported system failure to -date! It is this historical performance that has been the cornerstone of gulatory comfort with the ConVault protected AST product. Designed for Value The ConVault Protected AST system will provide ongoing value for fuel storage. More stringent regulations are consistently on the horizon; however, with a ConVault Protected AST the need for updating is greatly reduced. ConVault operating costs are substantially lower than virtually any other AST on the market. The concrete exterior provides protection for the secondary containment, and acts as a thermal mass, reducing temperature variations (which reduces fuel vapor loss and water vapor gain), while providing a non -corrosive, durable exterior. To meet your fuel storage needs, ConVault Protected AST's are manufactured in sizes ranging from 125 to 12,000 US gallons, or 500 to 45 000 liters (including multi -compartment options). ConVault AST's have a 20 or 30 -year warranty. ConVault Protected AST's are produced at manufacturing sites around the world. The unit is shipped as a finished assembly, normally limiting the need for major on-site work to providing a concrete pad and electrical service. Although the units are intended for f,; =- - stationary service, in the event of changing requirements %� + . L d L they can be moved and reinstalled. ConVault Protected AST's are thus an asset, compared to UST's or "tanks in dikes" which are usually considered a liability. Always consult local fire and building codes before installing a ConVault Protected AST since environmental and fire safety regulations can vary between jurisdictions.

Mt. Blaine at confluence of Clear Creek and Roan Creek. Prepared for: Chevron/Texaco USA Prepared by: WestWater Engineering 2570 Foresight Circle #1 Grand Junction, CO 81505 In Coordination with: Cordilleran Compliance Services, Inc. December 2006 Chevron Clear Creek 8 Inch Pipeline Integrated Vegetation and Noxious Weed Management Plan December 2006 Introduction On November 22, 2006, a field inspection of the subject pipeline was conducted by WestWater Engineering (WWE) biologists. The inspection identified appropriate topics for inclusion in an integrated vegetation and noxious weed management plan required by Garfield County Regulation 9.07.04 (13) (BOCC, 2006). Factors considered include soil type and texture, existing land management, absence or presence of listed noxious weeds and likely potential natural vegetation community. Landscape Setting Chevron Clear Creek 8 Inch Pipeline is on the first terrace above Clear Creek and generally follows the creek and road in a southeasterly direction before turning west and climbing the slopes of Mt. Blaine. At the northern terminus, Clear Creek was dry on the date of inspection (Photo 2). Southeast of the northern terminus a few hundred meters, high quality groundwater springs commence surface flow. The stream is lined with watercress, Nasturtium officinale with a heavy riparian deciduous shrub and woodland over story comprised of mountain boxelder, Acer negunclo and introduced and naturalized New Mexico locust, Robinia neo,nexicana (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 (NRCS, 2006b). Potential natural vegetation for meadows includes basin big sagebrush (Artemesia tridentata tridentata), western wheatgrass (Pascopw—urri smithii) and basin wildrye (Levnnts cinereus). For moderate, loamy slopes, needle and thread (Hesperostipa cantata cordata), bluebunch wheatgrass (Pseudoroegneria spicatum spicatum), Indian ricegrass (Ac/inatherum ht'menoides) western wheatgrass, Wyoming big sagebrush (A. 1. iii onringensis), and winterfat, (Krascheninnikovia lanata) is expected and was, to an extent, observed during the inspection by WWE. Similar vegetation on the steeper but still moderate, brushy slopes is expected with the Photo 4. Typical natural vegetation. Photo 5. Shrubland near turn to west. addition of bottlebrush squirreltail (Sitanion hi strix) 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 trapped. 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 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. Allow plants to expend as much energy from root system as possible, do not treat when first emerging in spring but allow growth to bud/bloom stage. If seeds develop, cut and bag if possible. 1. Hand grub (pull), hoe, till, cultivate in rosette stage and before flowering or seed maturity. seeds develop, cut and bag seed heads. If 2. Chop roots with a spade below soil level. 5. Hand pulling is generally not recommended for perennial species unless you know the plants are seedlings and not established plants. Hand pulling can be effective on small patches but is very labor intensive because it must be done repeatedly. 3. Treat with herbicide in rosette or bolting stage, before flowering. 4. Mow biennials after bolting stage, before seed set. Mowing annuals will not prevent flowering but can reduce total seed production. Herbicide treatment with two or more herbicide modes of action in fall (after approximately August 15 when natural precipitation is present) is the best method to control difficult perennials such as Canada thistle. The resilience of Canada thistle and its ability to quickly develop immunity to herbicides, particularly those used incorrectly, makes it imperative to use the proper chemicals at the correct time in the specified concentration. Most misuse seems centered around excessive use either in frequency or concentration. This results in mostly top kill and an immune phenotype. Table 3. Treatment Strategies for Perennials Target: Deplete nutrient reserves in root system, prevent seed production 1. Allow plants to expend as much energy from root system as possible, do not treat when first emerging in spring but allow growth to bud/bloom stage. If seeds develop, cut and bag if possible. 2. Herbicide treatment at bud to bloom stage or in the fall (recommended, after August 1.5 when natural precipitation is present). In the fall plants draw nutrients into the roots for winter storage. Herbicides will be drawn down to the roots more efficiently at this time due to translocation of nutrients to roots rather than leaves. If the weed patch has been present for a long period of time, another season of seed production is not as important as getting the herbicide into the root system. Spraying in fall (after middle August) will kill the following year's shoots, which are being formed on the roots at this time. 3. Mowing usually is not recommended because the plants will flower anyway; seed production should be reduced. Many studies have shown that mowing perennials and spraying the re -growth is not as effective as spraying without mowing. Effect of mowing is species dependent; therefore, it is imperative to know the species and its basic biology. Timing of application must be done when biologically appropriate which is not necessarily convenient. 4. Tillage may or may not be effective. Most perennial roots can sprout from pieces only 1/2" - I" long. Clean machinery thoroughly before leaving the weed patch. 5. Hand pulling is generally not recommended for perennial species unless you know the plants are seedlings and not established plants. Hand pulling can be effective on small patches but is very labor intensive because it must be done repeatedly. 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, Onobrvchis 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. [n 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 WWE are related to incomplete control caused by high concentrations killing top growth before the active ingredient can be transported to the roots through the nutrient relocation process. Most herbicide applications should use a surfactant as directed on the herbicide label or other adjuvants as called for on the herbicide label. Grazing: There is currently heavy grazing on much of the pipeline route as evidenced by plant utilization observed on 11-22-2006. Initial observations indicate areas currently open to cattle grazing harbor the greatest distribution, diversity and density of weeds. Grazing should be controlled in a manner to enhance rather than diminish the plant community. Certain noxious weeds are highly palatable during short stages of the life cycle to certain grazing animals including goats, sheep, mule deer, elk, cattle and horses. Preparation and implementation of an appropriate grazing management plan should be considered. Photo 6. Severe meadow erosion. Mechanical: Photo 7. Typical meadow with burdock. It is recommended senescent, seed -bearing, listed weeds on the route and adjacent to the route be cut, bagged and disposed of in a licensed landfill. Rosettes can be cut with a shovel below the Photo 8. Seed bearing burdock. Photo 9. Seed bearing musk thistle. Photo 10. Houndstongue rosette. Photo 11. Scotch thistle rosette. surface of the soil on plants which are not yet dormant. Even with some seed drop, cutting and bagging will greatly reduce seed release. Future need to do mechanical or other control methods should be reduced after only two seasons of cutting and bagging. Alternative Methods: Some noxious weeds are subject to damage from beneficial insects. Included are Canada thistle stem alining beetle, Ceutarhvnchus Intra, Canada thistle bud weevil, Larinus planus, musk and plumeless thistle rosette weevil, Trichosirocalus hurridus, Canada thistle stem gall fly, Urophora cardui, and thistle defoliating beetle, Cassida r-ubiginosa, 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-mycon•hizal 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 V/AMF. The latter are applied to weed patches and are reputed to greatly increase competition of native plants with Canada thistle in particular thereby affecting a non -chemical control of some noxious weeds. Revegetation Soil types on the property support many of the same species of native vegetation. As stated previously, the recommended nix 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 fo • this site. (NRCS, 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 • 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.

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 govem our response to any emergency situation: 1 The safety of employees takes precedence over all other considerations. 2. We will minimize impact on the environment once the safety of all personnel has been secured. 3. We will endeavor to minimize damage to or loss of property and equipment. keeping safety and environmental concems at the top of our priority list. Emergency Action Plan: Scope: This written plan covers the designated actions employees (Chevron & Contractors) associated with the Skinner Ridge Delineation Project (Pieance 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 at employees shall evacuate per posted instructions (if applicable) and report to the following designated muster points'. Primary Muster Point: Hiner Gate (N39 Deg 32.474 W 108 Deg 19.518 Elevation 5839) Alternate Muster Point: Cowboy Chapel (N39 Deg 29.115 ft, W 108 Deg 19,705 ft Elevation 5506) Field Rally Point: Main Deer Camp approx. 2.1 miles north of Hiner gate on right hand side of road at log cabin. (N39 Deg 34.311 ft. W 108 Deg 20.776 ft Elevation 5985) Note: See attached map. Operator (Person In Charge) is designated to perform a final building check to ensure all temporary/portable office building/s have been evacuated in the event of an emergency. Designated 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 facilitiy/s: Building Energy Type Utility Shut-off Location Temporary On -Site Office — Drilling or testis location. Electricity- Generator Propane/Diesel fired devices. Posted at entrance to Drilling rig location. Visitors are required to sign a logbook upon entering any field office or location whether permanent or temporary. They will be required to note the time of their arrival, work location, emergency contact numbers (if not already on file) and departure time from the facility. In the event of an emergency, Chevron personnel will use the logbook, verbal communication, cell or satellite phones and/or radios at the muster point to account for all personnel. If necessary, available, pre -designated personnel may initiate a search for any missing person as long as it is safe to do so. For Field Work sites, personnel present on location are noted by crew leaders and supervisors. Emergency muster points are pre -established and should be discussed daily before each job during (JSA) job safety analysis. In the event of an emergency, personnel will evacuate to the designated muster point where a headcount will be conducted. Employees who have been certified in First Aid/CPR and have received Bloodborne Pathogen training may render assistance to injured employees.

Box 3543 Grand Junction, Colorado 81502 BLM Antiquities Permit No. C-52775 Submitted to Bureau of Land Management Grand Junction Field Office 281514 Road Grand Junction, Colorado 81506 Abstract Grand River Institute (GRI) conducted a Class 111 cultural resources inventory of two proposed pipeline route segments in the Clear Creek and Deer Park areas of Garfield County, Colorado, for ChcvronTexaco. 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 315' and June 151 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 -1P), and to make management reconuncndations for those sites found to be eligible or potentially eligible. The files search identified three historic sites within the project corridors. Two sites (5GF424 and 5GF5425) are structures near the mouth of Clear Creek and one site is reportedly an historic race track (5GF351), all occurring on private property. The Roan Creek Community Center (5GF424), was revisited just last year for another project so a new reevaluation form was not completed for this site. The Roan Creek School House (5GF425) was previously field evaluated as eligible for listing on the NRHP. Site 5GF425 was reevaluated as "field not eligible" for listing on the NRHP. 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. ii Table of Contents Introduction 1 Location of the Project Arca 1 Environment 1 Summary of Files Search and Literature Overview 2 Study Objectives 4 Field Methods 4 Results 4 Site Significance 5 Site Description 5 Discussion 7 Summary of Site Evaluations and Recouttnendations 8 References 9 Appendix A: Tables of Previously Recorded Cultural Resources and Bibliographic List of Previously Conducted Inventories A.1 Appendix B: OAHP Site Form B.1 List of Figures Figure 1.

These segments total approximately 8.5 miles long, of which 6.85 miles are located on private lands and 1.65 miles are on Bureau of Land Management administered property. A total of 166 acres of private property and 40 acres of BLM land was surveyed. The survey and report preparation were conducted by Carl E. Conner (Principal Investigator), Barbara J. Davenport, Nicole Darnell, Jim Conner and Dana Archuleta. A files search was completed on 19 May 2005, and the field inventory was carried out on May 3151 and June 1 s" 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 T. 6 S., R. 98 W., Sections 4, 9, 10, 11, 15, 22, 27, 33, and 34; 6111 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 cattinued'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 sluublands, 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 fanning) has pushed most large mammals into the surrounding mountains. There, mule deer, elk, coyote, and black bear are common, as are cottontail rabbits, beavers, and various rodents. Mountain lion, bobcat, fox, skunk, badger, and weasel are also likely inhabitants. Bird species observed in the area include the jay, raven, red -shafted flicker, long-eared owl, and various raptors. There is little climate variation within the study area. These relatively low elevations are host to a cool semiarid climate where temperatures can drop to -10 degrees F during the winters and summer temperatures may reach 100 degrees F; there is a maximum of 120 frost free days and the annual precipitation is about 14 inches. The surrounding higher elevations are characterized as cooler and moister. Annually, the high mountain temperatures could average 5 degrees cooler and the precipitation as much as 14 inches greater that the surrounding low elevations (USDA SCS 1978:244). 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 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. 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 (Husband 1984). A more specific document regarding the Euro -American settlement of the study area is History of Roan Creek and De Beque (Prather and de Beque, n.d.). As therein described, in the De Beque - Roan Creek area, the first to file homestead claims were Robert Eaton, L.T. Stewart and George Gibson along Dry Fork. Brothers Harve and John Van Cleave filed claim to Roan Creek property and established a cattle business in 1883 that became well known in Western Colorado. Other creeks in the area are named for the early ranchers who often brought cattle and cowboys with them. Kimball Creek is named for Gayton and William Kimball. Con [now Conn] Creek is named for C.H. Conwell. Tom Wallace set up his outfit on Wallace Creek, and John Carr on Carr Creek. George and Frank Newton settled on Clear Creek --apparently named before they arrived. The importance of water --and water rights --to the settlers not only was acknowledged by naming the creeks after them but also by so naming the ditches. Accordingly, one will also find the familiar names of Charles Creek, Joe Newman, A.S. Hhnebaugh, Henderson Frashier, Toin King, George P. Anderson, George Hayes, and W.A. DcLaMatyr on ditches and ranches of the surrounding area. 13y 1888, at least 31 ranches were in active operation, and a total of 140 cubic feet of water had been filed on (ibid.:3-4). The town of De Beque is named for Dr. W.A.E. de Beque, who arrived with three companions (Fred Webster, John Boudin and Dick Smith) in the spring of 1884. He established a ranch on the banks of the Grand River near its confluence with Roan Creek. The first post office was within a log building built by Dr. de Beque, which served as his office, a drug store and a general store. Marie de Beque was the first Postmistress, officially named so in 1888. During this year, the town site of De Beque was established outside the boundary of the de Beque's ranch on what was originally the H.L. Spencer homestead. It was platted by surveyor John Walzl and given the name of De Beque in February of 1888. Shortly thereafter, Dr. de Beque built the first residence in the town (ibid.:3-4). Adjacent to Ravensbeque (Dr. de Beque's ranch), the first school was started in 1886 by Mrs. Joseph McMillen, who initially began teaching her own children, but soon took in others from the surrounding homesteads. About that same time, a public school was opened on Con [Conn] Creek. Later, county schools were opened on Brush Creek, Kimball Creek, Dry Fork and main Roan Creek. The school started by Mrs. McMillen was moved to town where various buildings served as classrooms 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 (NRNP), and to make management recommendations for those sites found to be eligible or potentially eligible. Based on the files searches cultural resources were expected to be encountered. Field Methods A CIass 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 (NAPA) directs the BLM to ensure that BLM-initiated or authorized actions do not inadvertently disturb or destroy significant cultural resource values. Significance is a quality of cultural resource properties that qualifies them for inclusion in the NRNP. The statements of significance included in this report are field assessments to support recommendations to the BLM and State Historic Preservation Officer (S1{PO). 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 NRIIP eligibility, which is used to assess a site's research potential: The quality of significance in American history, architecture, archaeology, and culture is present in districts, sites, buildings, structures, and objects of State and local importance that possess integrity of location, design, setting, materials, workmanship, feeling, and association, and a) that are associated with events that have made a significant contribution to the broad patterns of history; or b) that arc associated with the lives of persons significant in our past; or c) that embody the distinctive characteristics of a type, period, or method of construction, or that represent the work of a master, or that possess high artistic values, or that represent a significant and distinguishable entity whose components may lack individual distinction; or d) that have yielded, or inay 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 OAHP Site Form (available at the BLM and OAI-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 I-Iistoric Places. No further work is necessary. Site 5GF424 is the Roan Creek Community Club building complex and is presently in use as the "Cowboy Chapel of Prayer." The site was previously recorded, however, that form was not signed or dated and contains limited information. The site is located at the confluence of Clear Creek (County Road 211) and Roan Creek (County Road 204) at an elevation of 5520 feet. Vegetation on the site is grass and the surrounding open areas contain sagebrush. Most of the ground around the structures is barren and includes a dirt parking area. The main focus of the site is a large milled log structure which measures 54 feet in length by 30 feet in width and rests on a concrete foundation. The south side (front) of the building has double door entryway which measures 7 feet by 15 feet and contains two, five- horizontaI 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 patient 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 Ianding, stairs and iron hand rails at the entryway seem to have been replaced fairly recently. Approximately ten feet from the northwest corner of the main log structure is a storage shed which measures 12 feet by 8 feet and is constructed of milled lumber with a metal shed style roof. This building has a single 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 and is currently in use. This structure is referenced in a booklet entitled, "Cattle and Shale, 1884-1984, A Story of Roan Creek and Dc Balm" in the section that discusses families and ranching on upper Roan Creek. The description from pages 13 and 14 is as follows: "A community hall, "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-Iimebaugh 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 Recomtnendation 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, alt measuring approximately 24" by 60" overall. All these windows arc authentic divided lite with a 2W1 H 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 13eque," but none was found. Despite this, the estimated time of construction is ca. 1930. Evaluation and Management Recommendation This site does not appear to meet criteria for National Register status (36 CFR 60.4 a, b and c). The structure seems to be structurally unsound as it is listing to the east. Given its deteriorating condition and lack of historic artifacts or references, and due to a perceived lack of potential for this site to yield additional significant information regarding the area's history, it is field evaluated as not eligible for listing on the National Register of Historic Places. No further work is necessary. Discussion This project has provided an opportunity to continue the investigations into the Clear Creek and Deer Park Valleys. As expected, historic structures were the site type encountered by the inventory. One such site was re-recorded. Other farm and ranch complexes are present near the pipeline route that are likely to date to the first half of the twentieth century. Limitations to the study included the disturbance of much of the proposed routes by previous construction activities (road, ditch, fence, etc.) or by cultivation. Summary of Site Evaluations and Recommendations The eligibility determination and consultation process is guided by Section 106 of the NHPA (36 CFR 60, 63, and 800). Inventory to identify, evaluate, and mitigate potential effects to cultural resources affected by an undertaking is the first step in the Section 106 process. BLM actions cannot be authorized until the Section 106 process is completed (36 CFR 800.3). Final determinations of National Register eligibility and effect are sought from the controlling federal agencies in consultation with the State Historic Preservation Officer (SHPO) and the Advisory Council on Historic Preservation. The files search identified three historic sites within the project corridors. Two sites (5GF424 and 5GF5425) are structures near the mouth of Clear Creek and one site is reportedly an historic race track (5GF351), all occurring on private property. The Roan Creek Community Center (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 NRFIP. 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 IIusband, Michael B. 1984 Colorado PIateau Country Historic Context. Colorado Historical 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 sparveritrs); 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 I 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 likely that fledging would occur around July 30. The status of nest # 1 is unknown (either eggs or chicks) and if the adults were incubating at the time of the survey, fledging may not occur to sometime in mid- August. The active Cooper's Hawk nest sites #'s 1 and 2 are located about 105 feet and 265 feet from the centerline of the pipeline ROW, respectively (Figure 1 and 2). The proposed pipeline construction will result in increased human activity and vehicular traffic in the vicinity of the nest site, increasing the potential of nest failure. What is not known is the level of vehicular/human activity that would cause these nesting pairs to abandon the nests. The Colorado Division of Wildlife does not have a recommended buffer for Cooper's Hawks; however, it is our opinion that a one-quarter mile buffer zone around this nest would decrease the likelihood of nest failure due to project related disturbance. Nests # 2 is located in a box -elder tree about 300-400 feet east of an active drill pad west of Clear Creek. This pad has apparently received a substantial amount of activity and daily traffic and these birds have shown a tolerance for this level of disturbance. In general, raptors have a higher tolerance to occasional vehicular traffic and a lower tolerance to "constant" human -related activity on the ground. It is generally accepted by avian biologists that raptors have a stronger fidelity to their nest site after young have hatched and are more apt to abandon their nest site in response to disturbance during incubation.

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 pinon-juniper along Clear Creek and on the westward portion of the pipeline bisects possible Uinta Basin cactus habitat but no plants were observed.
