Garfield County, Colorado Approved 11-06-06 Resolution 2006-115 as recorded: Bk 1877, Pg. 134: Garfield County, Colorado Dear Commission: Williams Production RMT Co. respectfully requests the above referenced Special Use Permit be extended for the period of one year on the basis of continued use of the facility during the remainder of 2007 and 2008. In light of current drillings plans proposed for the Trail Ridge project area, one drill rig will be drilling 10 wells throughout the winter months (November 15, 2007 — March 31, 2008) from a COGCC approved drill pad in Section 16: T5N-R97W. The intent is to leave the existing approved Temporary Living & Storage Facility where it is currently located in Section 3: T5S- R97W and transport workers/employees to and from the existing facility. The one year extension will accommodate both drilling and completion operations for wells referenced above. Leaving the facilities in their current location will allow Williams Production RMT Co. to minimize overall surface disturbance, utilize existing transportation routes, utilize existing infrastructure, and minimize winter traffic to and within remote areas. All facilities including 24 person camp, catering, ISDS, potable water storage, and bear proof trash containment are consistent with the above approved Special Use Permit. All existing camp facilities meet or exceed CDH, CDPHE, Colorado Division of Fire Safety, and 2003 IBC including but not limited to snow load requirements and fire suppression systems. Should you h.v- any questions or concerns regarding this matter, feel free to me @ (303) 606- 4357.

Drainage is approximately 7% to the northwest. A percolation test/soils evaluation was conducted on the property of reference on 09/19/06 by Tom A. Cronk, registered professional engineer (R.P.E.). The perc excavation trench (excavation A) was located approximately 410' southwest of the first well head located on the parcel and approximately 25' northwest of the access road. Additional perc holes were located 45' northwest of the access road (excavation B) and 70' northwest of the access road (excavation C). The 09/19/06 investigation was intended to develop subsurface design parameters for an individual sewage disposal system (ISDS) to serve a proposed commercial man camp at the site. Because of the commercial nature of the project, an engineered ISDS design was prepared for the project on 09/30/06. The 09/30/06 ISDS design utilized a pressurized lift station to allow flexibility with respect to placement of temporary housing facilities at the site. Upon inspection of the site by the ISDS installation contractor in early October, 2006, it became apparent that gravity discharge of sewage was feasible pending berm cover of the effluent line from the office structures to the absorption field. In an effort to simplify the installation and reduce the cost of the ISDS, the original 09/30/06 ISDS design has been revised to facilitate gravity discharge of sewage to the absorption area. The 09/19/06 perc test/soils evaluation is attached for reference as Appendix A. A discussion of developed subsurface design parameters and the revised engineered ISDS design follows. 2.0 Development of Design Parameters A pert excavation trench (excavation A) was extended to a depth of 96" below ground surface (BGS). There was no evidence of ground water or high seasonal water table in the open excavation to a depth of 96" BGS. The soils evaluation indicates three distinct soil horizons underlie the site. A Ethological description follows: depth (in.) description 0" - 12" clayey sand loam, dark brown; loose and friable 12" - 60" tan sandstone gravel in light brown sandy clay/clayey sand matrix 60" - 96" weathered sandstone, tan An INFILTRATOR trench absorption field configured in serial distribution is proposed for the site. A design perc rate of 60 min/in. is chosen for overall system sizing. Page 2 of 9 3.0 System Design A INFILTRATOR absorption trench is proposed for discharge of septic effluent at the site. Construction of the system will consist of excavating level trenches in the area comprising the absorption field. As shown in the attached septic layout plan, the trenches will be oriented perpendicular (i.e., long axis northeast to southwest) to the natural slope (northwest) to minimize the depth of excavation along the trench length. Each trench excavation shall be continued to a maximum depth of 48" BGS at the uphill side of the trench (see absorption field cross-section). After removal of surface soils, the open excavations will be disked or scarified to promote subsurface absorption. Following completion of the initial push -outs, INFILTRATORS will be used to construct a septic effluent distribution system in the open excavations. The INFILTRATOR effluent distribution system will be installed in accordance with the "Infiltrator Technical Manual", available from Infiltrator Systems Inc., 123 Elni Street, Suite 12, Old Saybrook, Connecticut 06475. Adjacent INFILTRATORS shall be fastened with a minimum of four (4) 3/4" x #8 self -tapping sheet metal or bright brass deck screws to prevent movement and separation during backfilling. Septic effluent will be transferred from the upper trench to each of the adjacent downhill trenches through a serial distribution network as shown in the attached construction details. The serial distribution connections between adjacent trenches will facilitate the saturation of the up hill trench before septic effluent is allowed to flow to each of the adjacent downhill trenches. As shown in the attached Absorption Field Cross Section, the bottom of the INFILTRATOR seepage trenches will be located a maximum of 48" below ground level. The installation will provide 48" of usable infiltration soil between the bottom of each INFILTRATOR trench and the underlying subsoils. After the INFILTRATORS are installed, the absorption field will be covered with a soil cap. The soil cap will consist of approximately 36" of native soil. A minimum of 5% slope will be maintained to promote surface run off away from the absorption field. The installer should confine the feasibility of gravity discharge of sewage effluent from the residence to the absorption field by field verification of assumed design parameters. Assumed design parameters with respect to gravity discharge include: • distance from the sewage pipe at exit from the foundation line to the absorption field - 150' or less, • elevation of the ground surface at entry to the absorption field shall be 6" or less above the invert elevation of the sewage pipe at exit from the foundation line. If field measurements do not confirm these design assumptions, gravity discharge of sewage effluent from the existing residence to the absorption field can not be assured and a lift pump may be required. Please contact the design engineer to address any design modifications necessary for effective operation of the ISDS if the above design assumptions are not upheld. The installer must also confirm the setbacks from property lines, building envelopes, and existing easements shown in the attached graphics are maintained. Additionally, any unknown utility lines, easements, or other adverse conditions disclosed during construction must maintain the required setbacks listed on page 6 of this document. A minimum of 12" (36" recommended) of soil cover is required for all effluent piping and the absorption field (excepting maximum 8" soil cover over septic access ports). Page 3 of 9 Provide high density 1-1/2" blue board insulation cover over all effluent lines with less than 30" cover in all non -traffic areas. Additionally, all effluent lines under vehicle traffic areas shall be minimum Schedule 40 and shall be covered with flow fill and high density 1-1/2" blue board if less than 12" of cover. Finally, 4" clean outs shall be provided at maximum 100' intervals in all effluent lines exceeding 100' in length. The ISDS will be designed to accept sewage discharge from a twenty four (24) person man camp. The man camp will provide sleeping, eating and laundry facilities for the occupants. Sewage loading estimates follow: source work camps with toilets laundry facilities garbage grinder and misc. loading factor average daily sewage flow (gal/day) 24 employees @ 50 gal/person-day 1200 gal/day 24 employees @ 20 gal/person-day 480 gal/day 24 employees @ 5 gal/person-day 120 gal/day Total Average Daily Flow 1,800 gal/day A minimum 3,375 gallon septic tank is required to provide 30 hours of retention capacity for sewage generated at the above estimated rate. To obtain the required retention capacity, a 2,000 gallon single compartment septic tank (i.e., interior baffle removed) will be placed in series and ahead of a 1,500 gallon single compartment septic tank. Finally, a 1,500 gallon standard two compartment septic tank will accept sewage from the office trailers and crew changing facility (see attached septic layout plan). As discussed above, an INFILTRATOR system is proposed to discharge septic effluent to the underlying sub -soils. As shown in the attached graphics, the absorption field will consist of 216 QUICK4 INFILTRATOR units configured in serial distribution as setbacks allow (maximum of individual trench length of 100'). The absorption field will encompass a gross area of 2,592 square feet with an effective area (9.87 sq. III INFILTRATOR plus 50% reduction factor) of 4,263.84 sq. ft. Calculations and design parameters used to size the absorption field follow.

If at any time during construction, subsurface site conditions are encountered which differ from the design parameters developed in Section 2.0 construction activities will stop and the design engineer will be contacted to address any necessary design modifications. • Installation procedures including grade, location, setbacks, septic tank size, and absorption field size shall conform with the attached graphic details. Construction activities and system components will not encroach upon existing easements or utility corridors. A minimum of 6 ft of undisturbed soil shall be maintained between individual absorption elements and the septic tank and/or adjacent absorption elements. Minimum site specific setbacks for system components are: Source Septic Tank Absorption Field Building Sewer water line 10' 25' 10' domestic well 50' 236' 50' domestic cistern 25' 25' dwelling 5' 20' property lines 10' 10' dry gulch/int. irrig. 10' 161' pond/lake/stream 50' 186' lined water course 25' 25' irrigation ditch open 50' 186' lined/gated 25' 25' solid pipe 10' 10' • All gravity flow sewer lines and effluent distribution piping shall be 4 inches in diameter and have glued joints. INFILTRATORS shall be placed level in the absorption field. All lines discharging sewage from the residence to the septic tank shall maintain fall of between 1/8 in. and 1/4 in. per foot and shall employ sweep 90's or 2-45's at all turns. Sewer lines from the dwelling to the septic tank and at least 6 ft from the septic tank outlet must meet minimum standard ASTM -3034. Sewer lines under driveways shall always meet minimum Schedule 40 PVC standards and shall be encased with corrugated metal pipe or flow fill and minimum 1-1/2" high density blue board when covered with less than 12" of soil. • A minimum of 12" (36" recommended) of soil cover is required for all effluent piping and the absorption field (excepting maximum 8" soil cover over septic access ports). Provide high density 1-1/2" blue board insulation cover over all effluent lines with less than 30" cover in all non -traffic areas. Four in. sanitary clean -outs shall be installed at Page 6 of 9 maximum 100' intervals in all effluent lines exceeding 100' in length. • The installer shall not place fill in the open excavation until inspected and approved by the design engineer. Additionally, the final cover shall not be placed on sewer lines, septic tank, or the absorption area until the system has been inspected and approved by the design engineer. The installer shall provide 48 hour notice to the engineer for all required inspections. • The effluent distribution system shall be constructed in accordance with the "Infiltrator Technical Manual" available from Infiltrator Systems Inc., 123 Elm Street, Suite 12, Old Saybrook, Connecticut 06475. • Adjacent absorption field trenches shall be connected by a serial distribution system to assure saturation of the upgradient trench before effluent is passed to the adjacent downgradient trench (see attached absorption field plan view and cross section details). • The surface cap shall be mounded 5% over the absorption field to promote surface runoff. • The system contractor shall be aware of the potential for construction activities to reduce soil permeabilities at the site through compaction, smearing, and shearing. The following precautions and construction procedures should be employed during installation to minimize disturbance to native soils: Excavation should proceed only when the moisture content of the soil is below the plastic limit. If a sample of soil forms a rope instead of crumbling when rolled between the hands it is too wet and should be allowed to dry before excavation continues. Excavation and backfill equipment should work from the surface where at all practical to avoid compaction of the soils at depth. iii. The bottom and sidewalls of the excavation should be left with a rough, open surface. The appearance should be that of broken or ripped soil as opposed to a sheared, smeared, or troweled surface. Any smoothed or smeared surfaces should be removed with a toothed rake or shallow ripper taking care to remove loose residues from the bottom of the excavation by hand if necessary. iv. Care should be taken in placing fill materials in the excavation to avoid damaging the exposed soil surfaces. Page 7 of 9 4.2 Operation - Maintenance and Inspections • The owner shall install a structural barrier if necessary and take precautions to prevent vehicular traffic, excessive surface watering, accidental flooding, or other activities in the vicinity of the absorption field which may compact, saturate, or otherwise alter the subsurface soil parameters used in designing the septic system. • The owner will plant and maintain grass or other shallow rooted cover crop to prevent erosion and promote evapotranspiration over the absorption field. • The owner will inspect and maintain the required mounding and drainage away from the absorption field to prevent saturation from precipitation and surface flows. • To mitigate the generation of preferential flow channels which may compromise the operation of the system, the owner will inspect and prevent intrusion of burrowing animals and deep rooted plants into the absorption field. • The owner will conduct periodic maintenance of the septic system by removing accumulated sludge from the septic tank every 3-4 years to prevent clogging of the absorption field.

Drainage is approximately 7% to the northwest. A percolation test/soils evaluation was conducted on the property of reference on 09/19/06 by Tom A. Cronk, registered professional engineer (R.P.E.). The pert excavation trench (excavation A) was located approximately 410' southwest of the first well head located on the parcel and approximately 25' northwest of the access road. Additional perc holes were located 45' northwest of the access road (excavation B) and 70' northwest of the access road (excavation C). A perc excavation trench (excavation A) was extended to a depth of 96" below ground surface (BGS). There was no evidence of' ground water or high seasonal water table in the open excavation to a depth of 96" BGS. The soils evaluation indicates three distinct soil horizons underlie the site. A lithological description follows: depth (in.) description 0" - 12" clayey sand loam, dark brown; loose and friable 12" - 60" tan sandstone gravel in light brown sandy clay/clayey sand matrix 60" - 96" weathered sandstone, tan Page A-1 of A-3 Pert holes were constructed in excavation A at the surface and at depths of approximately 40 in. and 80 in. Additional perc holes were constructed in excavation B at the surface and at depths of 36 in. and 72 in., and in excavation C at the surface and at depths of 32 in. and 66 in. The holes appeared to be well saturated at the time of the test. Results of the percolation test are shown in Table I.

The following site-specific considerations should be observed during implementation of the ISDS: • The bottom of the ISDS absorption field should be located no deeper than 48" BGS to maintain 4' of usable infiltration soil above the extent of the soils evaluation excavation located at 96" BGS. A design pert rate of 60 min/in. is recommended for overall system sizing. • Care should be taken during construction to avoid compaction and smearing of the exposed infiltrative surfaces and preserve the natural permeability of the native soils.

Williams currently holds 23,000 acres of mineral leases in this portion of Garfield County. This field is known as "Trail Ridge" and has been operated by Williams for five years. We currently operate 31 natural gas wells in the field and plan to drill an additional 9 wells in 2006. In aggregate, Williams expects to drill over 1,500 wells in the Trail Ridge field over the next 20 years. Numerous facilities similar to this one are expected to be utilized over the next decade. The primary purpose of this facility is to house all essential drilling personnel during the winter months. Suitable permanent housing inventory is not available in this area. In fact, the nearest housing is approximately 2-1/2 hours away by car. This facility will not pose any threat to any local lodging or housing businesses. In addition, hotels and motels in Rio Blanco and Garfield Counties are currently at full capacity. The facility will be co -located on a COGCC-approved drilling rig "pad" together with standard drilling rig facilities. The facility will be in use from November 2006 through May 2006 and will be managed by catering and rental companies that specialize in these types of facilities. PTI/Crown Camp Services will be responsible for the housing, catering and laundering services. PTI will supply a single "camp attendant" that will supervise the operation of this facility. Depending on the outcome of this pilot phase, the need for this facility may need to be extended for an indefinite period of time. Williams Production RMT Co. would respectfully request this Special Use Permit to be valid until June 1, 2008. This date would allow for operations across two full winter seasons. Given the late start of this year's program, a full winter pilot will not be realized. Please refer to exhibit #1B for a general regional layout of the drilling pad and the associated wells that will be drilled from it. Exhibit #1C details the living and storage facilities and the layout of these as compared to the traditional drilling equipment on the pad. This exhibit is included in the approved well permit from the Colorado Oil and Gas Commission. In addition, as per COGCC requirements, this exhibit was submitted to Garfield County, attention to Mr. Jess Smith, on July 20, 2007. No comments regarding this application were received. Exhibit #1D provides a more detailed and more current pictorial of the pad layout. This will be Williams' first attempt at drilling wells in this area during the winter season. In order to conduct operations during the winter efficiently and safely, we've concluded that all personnel associated with the drilling operation are essential and Page 1 of 10 must remain on location. Drilling natural gas wells is a 24 -hours per day operation, thus normally requiring numerous shift changes, equipment transfers, and transportation in and out of well sites during any given day. The types of vehicles that will be accessing the site, at least preliminarily in order to get it stocked, will be standard pickups, passenger vans, semi trailers loaded with drilling materials, and large pump trucks. A possibility also exists that a helicopter will be used to transfer crews to and from the facility. This would also be the case in an emergency requiring an immediate evacuation (see "Emergency Services" below). The drilling rig crew will be operating on a two weeks on/two weeks off shift schedule, with one week consisting of 7 days. However, given the winter conditions to be encountered, travel to and from this site will be limited at times. Winters are generally mild in this area of the state, however, two or three storms annually can essentially prohibit any type of road access to the area. With this in mind, Williams has decided to plan this facility for a "stranded" scenario, in which multiple crews could be "stranded" on the location for 2-3 days at a time. The standard number of people that will be housed at the facility will be 24. The absolute maximum number of people in the "stranded" scenario would be 54. Everybody that will be present at the drill site will not necessarily use the Temporary Housing and Storage Facility. For instance, the Williams drilling foreman will have his own trailer on the drill pad. Please refer to the table below which outlines the essential personnel who will be using this faci ity.

In order to meet IBC 2003, each room will only occupy two workers. Please refer to Exhibit #1N for the floor plan, dimensions, and specifications of this unit. 90'x98'storage shed for steel casing, cement materials, excavation equipment, and maintenance tools (Exhibits #1E, #1F, and #1G) (this structure will be permitted separately through Garfield County) 3 4000 gallon potable water storage tanks 3 70 kW generators Exhibits #1H through #1M illustrate several of the structures listed above. All of the equipment and structures will be powered via generators on-site. Therefore, no electric utilities additions will be required. These buildings are designed for use in arctic areas such as Alaska and Canada, thus they are air -tight and will not allow for any type of influx of rodents. The trailers will meet or exceed the 75 psf snow load requirement as per IBC 2003 at this elevation (8,500' above sea level). Directions to Facility From Kentucky Fried Chicken in northern Rifle: • Take County Hwy 13 north approximately 19 miles to the Rio Blanco Store • Turn left on Rio Blanco County Road 5; travel approximately 19 miles to MTW gate (brown trailer house on left) • Go through MTW gate and security building and follow main road approximately 16 miles to the lease road on left • Follow lease road to the NE, keeping left for 2 miles to the facility Zone District Text Amendment Williams Production RMT has, under separate filing, applied for a text amendment to section 5.02.21 "Special Use Permits for Temporary Housing at Construction Sites" of the Garfield County Zoning Resolution of 1978 per section 10.01.01. This Special Use Permit application is being filed and reviewed concurrently with the text amendment request. We feel that this is the best approach to permitting this facility and will ensure compliance with the Garfield County Comprehensive Plan of 2000 and Garfield County Zoning Resolution. Description of Water Facilities In order to accommodate everyday living conditions, the Williams Temporary Storage and Housing Facility will be using water and will be dealing with wastewater. After consultation with contractors such as HB Rentals, Aramark, Clear Stream, and PTI Camp Page 3 of 10 Services who construct and operate these facilities regularly, as well as county health officials, the facility needs to be designed for a total of 80 gallons of water per person per day. This quantity encompasses all functions within the facility, including dining, food preparation, laundry, sewage, and sanitation and also allows for a contingency volume. Thus, the facility will be using and processing about 1,920 gallons of water per day. Williams plans to permit and construct one Individual Sewer Discharge Systems("ISDS") to accommodate the waste generated from this facility. This system will be permitted through Garfield County as per the ISDS Permit process and will meet all county and IBC codes and regulations that apply to these systems, including size, space, and accessibility. This process, as well as the associated soils testing, are in progress. In favorable weather, potable water can be hauled into the sites via a water hauling contractor. This water will meet the Colorado Department of Public Health and Environment for public water supplies. However, the goal is to have enough potable water on-site to last for 10 days, thus avoiding the need for transportation to and from the facility. The potable water will be supplied from the Meeker City Water Department and will be delivered in stainless steel tanks and at 3000 gallons at a time. The supplier, GTM, Ltd., use separate trucks and tanks exclusively for potable water. Please refer to Exhibit #10 in the application booklet for information regarding potable water supplies and hauling. This water will be treated prior to use in the facility. Due to the use of this facility during the winter season, all equipment, tanks, and lines will be winterized appropriately. In fact, the drilling rig equipment will include an additional boiler that will be capable of heating the water used for the drilling and housing operations. Due to the number of people serviced by this facility (24), and the use of ISDS systems, CDPHE permits (Wastewater Discharge Permit, Public Water System Permit) will not be required. No effluent of any type will be discharged on the surface. In addition, the facility will meet the exception criteria outlined in CDPHE sec 1.1 of 5 CCR 1003-1 for the primary drinking water regulations.

Without limiting the foregoing, Contractors' drug and alcohol testing policy for Work that is regulated by the Department of Transportation will meet or exceed Department of Transportation requirements and Work that is not regulated by the Department of Transportation ("DOT") will meet or exceed the requirements of Company's drug and alcohol testing requirements for Contractors not doing "covered" DOT work. The Contractor shall provide Company or designee with a copy of its written drug and alcohol testing policy, and, if requested, shall allow the Company or designee to audit its records and procedures pertaining thereto. Contractor will be responsible for ensuring that any subcontractor also meets the requirements imposed on Contractor under this Section 27. 28. COMPLIANCE WITH APPLICABLE LAWS AND COMPANY POLICIES. Contractor warrants that it is, and shall remain, in compliance with EPA, FLSA, OSHA, Department of Transportation, and other applicable federal laws and regulations, and shall cause its employees and subcontractors to comply with such applicable laws and regulations throughout the term of this Master Agreement and the applicable Request For Services. Contractor also warrants that it shall comply and cause all its employees, agents and subcontractors to comply with any and all policies, rules and/or procedures established by Company pertaining to the Work. Any Contractor performing Department of Transportation - covered tasks, shall furnish qualified individuals to perform the Company's covered tasks. A covered task is an activity that (a) is performed on a pipeline facility and (b) is an operation or maintenance task, and (c) is performed as a requirement of either 49 C.F.R. Part 192 or 49 C.F.R. Part 195, and (d) affects the operation or integrity of the pipeline. Contractor shall use a process for valuation and records retention acceptable to the Company and in accordance with 49 C.F.R. Part 192, 807 and 195.507. To the extent the Department of Transportation has placed pipeline transportation companies on heightened security alert, Contractor is responsible for heightened security to insure that persons non-essential to the performance of the Work or Page 6 of 10 foreign objects/items are not permitted at the Work Site. Contractor will be responsible for implementing security background checks for persons performing Work. One 6 cubic yard, bear -proof dumpster will be provided on-site. (Assuming 12 bedrooms and 1 kitchen (i.e. 13 unit equivalent) times 4 cubic feet = 52 cubic feet divided by 27 cubic feet per cubic yard= 1.92 cubic yard container. For sake of convenience, a 6 cubic yard dumpster will be provided on site). This dumpster will be constructed of steel and include dual steel lids. These lids are secured via the use of a steel bar across the top of the steel lids with positive connection and a hasp lock at the sidewalls to restrict entry into the dumpster. "Stranded" Plan As discussed above, this facility will be designed to handle an overflow of occupants in the case of a blizzard that immobilizes traffic in and out of the area. Based on the experience of company employees who have lived and worked in the area for decades, the worst of storms can cause traffic to cease for up to 72 hours. Therefore, Williams is comfortable in planning for a 10 -day contingency supply of water, food, and fuel. PTI's standard operating procedure is to stock 3 -weeks' worth of food at every venue such as this. Adequate tank facilities will be on-site to store 45,000 gallons of diesel fuel. Some portion of this diesel fuel will be used to run the generators that power the sleeping and dining facilities. The remainder would be used for the drilling operation. Finally, adequate tank facilities will be on-site to store 420,000 gallons of fresh water. The majority would be used for the drilling operation. Approximately 12,000 gallons of potable water will be stored in 3 tanks as a contingency for the housing and dining facilities. This water would be treated prior to use in the facility. Emergency Services Please refer to Section 11 in the booklet for a copy of Williams' Emergency Response Plan for all of the company's operations in Garfield County. This facility will be supplied with Class B or Class C fire extinguishers in readily accessible and readily visible locations. Enough extinguishers will be supplied in order for one to be located within any 100' radius. In addition, Williams will be constructing and supplying to the facility a mobile firefighting unit that is equipped with "Purple K" fire retardant. This unit is approximately 3'x3' in size. Williams has used this unit in other operations in Garfield County. Due to the use of this facility during the winter season, all equipment, tanks, and lines will be winterized. Thus fresh water tanks on location can be supplied with all-weather hoses to assist with any firefighting event. Williams and its contractors have reviewed recommendations distributed by St. Mary's CareFlight out of Grand Junction with regard to helicopter evacuation and landing zone specifications. The helicopter would require a 100'x100' clear and flat zone to land. This zone can easily be accommodated at the southwest end of the drilling pad. With regard to medical and other emergencies, Williams will be contracting a full-time on-site EMT/Paramedic/Safety/Security Administration Assistant. This person will be located at the facility 24 -hours a day and will be the first -responder in the case of a medical emergency and will also coordinate traffic flows, attendance monitoring, and helicopter operations (ie FlightCare) if needed. This person will be supplied by Page 7 of 10 CenterLine, Inc. This individual will also be responsible for monthly sanitation, safety, security, and fire protection inspections, as well as water usage and sewage disposal reports. This person will also oversee fire prevention efforts. Williams Production RMT Co. will provide detailed location descriptions, directions, and maps to all emergency service providers in county. Please refer to section 4 in the booklet for a detailed map and route to the facility. Site Plan Please refer to Exhibit #1D that illustrates the site plan and layout of this facility, in conjunction with the standard drilling facilities. The structures that will be associated with the Temporary Living and Storage Facility are outlined on page #1. All buildings will be installed and operated to meet all International Building Code 2003, International Plumbing Code 2003, International Mechanical Code, National Electric Code 2002, National Fire Protection Association, and International Fire Code 2003. Also, please note that no County or State roadways exist within one mile of this facility. Several private roadways will be used to access this site. After operations on this drilling pad are complete, it will be reclaimed as per guidelines from the Colorado Oil and Gas Conservation Commission. As shown in section 4 of this booklet, this location will be flat. Other than the drilling reserve pit, no significant amounts of standing water are expected. Topographical Description Please refer to Exhibits #1B that illustrates the topographical nature of this area. Please note that the entire pad will be flat and to grade. Construction of this pad has commenced. Garfield County Assessor's Map Please refer to Exhibit #5A which are Garfield County Assessor's Maps showing the subject property and all public and private landowners thereto. A listing of adjacent property owners is shown on Exhibit #5B. Deed Please refer to section 6 for documents that portray the progression of ownership of these lands. The Patent (Deed) showing the original transmittal of this acreage from the United States Bureau of Land Management to the Federal Oil Shale Co. The document titled "Certificate of Amendment of Certificate of Incorporation of Pacific Western Oil Corporation illustrates the name change from Federal Oil Shale Co./Pacific Western Oil Corp. to a new entity called Getty Oil Company. The other documents outline the name change from Getty Oil Company to Getty Oil Exploration Co. Also included is a certificate of merger that documents the transfer of ownership from Getty Oil Exploration Co. to Chevron U.S.A. Inc. Legal description of lands for which the Temporary Living and Storage Facility will traverse: portions of the NE/4SW/4 and portions of the NW/4SE/4 of Section 3, Township 5N, Range 97W. Page 8 of 10 Surface Owner (Chevron USA) Consent Chevron USA has agreed to the use of this surface as acknowledged in the attached letter dated July 12, 2006 (see section 7). Chevron USA has been privy to these plans for several months and has verbally accepted and supported this effort. Also, please see the attached lease agreement between Williams Production RMT and Chevron USA which allows for temporary "mancamps" as well as support structures on all associated leasehold. Please refer to section 7 of the application for these documents. Section 5.03 Review Standards (1) The proposed temporary housing and storage facility will be served by water hauled onto the site and stored in tanks. These tanks will allow the water to be distributed to the proposed units or in storage tanks attached to each unit. The water supplied will meet the Colorado Department of Public Health and Environment standards for public water supplies. All of these facilities will meet or exceed accepted engineering standards. Please refer to "Description of Water Facilities" section for greater detail. (2) Proposed traffic generated to the site will be the standard and existing traffic associated with Williams' drilling activity on the property. The proposed facility will generate a net reduction in the amount of daily traffic to this drilling pad location and should therefore reduce impact on the Garfield County road system. County roads that should benefit from this facility include CR 45, CR 213, CR 204, as well as others in Rio Blanco County. This net reduction of traffic will decrease dust, noise, glare, vibration, and adverse impacts on wildlife. (3) Due to the remote nature of the facility, minimal impacts on adjacent property will occur. Williams has received an approved Surface Use Agreement from Chevron USA. Please see the signed letter dated July 12, 2006 in the booklet. The Williams Production RMT Co. Temporary Living and Storage Facility will meet all applicable Performance Standards as detailed in Garfield County Supplementary Regulations 5.03.08. Potential Additional Sites As part of this application, Williams Production RMT Co. has outlined plans for additional facilities of this nature throughout Garfield County, primarily on the high plateaus.
