Hourly rates based on the hourly salary, and fringe benefits costs of the respective positions combined with an hourly overhead cost for the office will be used to establish the actual cost of County staff time devoted to the review of a particular project. Actual staff time spent will be charged against the Base Fee. After the Base Fee has been expended, the applicant will be billed based on actual staff hours accrued. Any billing shall be paid in full prior to final consideration of any land use permit, zoning amendment or subdivision plan. If an applicant has previously failed to pay application fees as required, no new or additional applications will be accepted for processing until the outstanding fees are paid. Checks, including the appropriate Base Fee set forth below, must be submitted with each land use application, and made payable to the Garfield County Treasurer. Applications will not be accepted without the required application fee. Base Fees are non-refundable in full, unless a written request for withdraw from the applicant is submitted prior the initial review of the application materials. Applications must include an Agreement for Payment Form ("Agreement") set forth below. The Agreement establishes the applicant as being responsible for payment of all costs associated with processing the application. The Agreement must be signed by the party responsible for payment and submitted with the application in order for it to be accepted.

Parachute Creek Gas Plant Expansion located at 4289 County Road #215 Parachute, Colorado. 1. Project Description: The proposed plant expansion is 'a 9.59 acre ea anskm4o the existing plant that was permitted in 2002 via Garfield Courity Resoluticrt 2002-67 dated June 17, 2002. - The Parachute Creek Gas Plant is located within a 1,333 -acre parcel owned by Williams Production RMT Co. The existing plant and the proposed expansion are well-placed within this property to reduce impacts on adjacent properties. Please see exhibit 6 - Vicinity Map. The Parachute Creek Gas Plant is utilized to collect natural gas from area gathering systems and process the natural gas by removing water, natural gas liquids and carbon dioxide (CO2) to provide the quality necessary for introduction to interstate natural gas pipelines. The existing plant design capacity is 100,000,000 standard cubic feet of natural gas per day (MMSCFD). The proposed plant expansion will expand capacity to 300 MMSCFD_ This additional plant capacity is needed by Williams Production RMT Co. to keep pace with the projected production curve. The removal of the carbon dioxide will additionally benefit American Soda. American Soda is applying for a Special Use Permit from Garfield County for a CO2 facility that Page 1 of 5 • • • will allow a portion of the CO2 removed from the natural gas to be put to beneficial use in the soda ash operation at American Soda. The plant expansion may necessitate additional line work. This work may include looping of the current 16" gathering line and a possible interconnection of the Parachute Creek Gas Plant and the Grand Valley Plant utilizing an existing 8" line. There are 5 new buildings proposed for the plant expansion. A. Office/Control Building- 75' wide x 75' long x 15' eave height. B. Amine Building- 70' wide x 100' long x 40' eave height. C. Compressor Building- 75' wide x 350' long x 35' eave height. D. MCC/Generator Building- 50' wide x 130' long x 40' eave height. E. Warehouse- 50' wide x 150' long x 40' eave height. These buildings are sized for maximum sizing and may be constructed in smaller dimensions. The plant operates 24 hours a day, 7 days a week and 365 days per year. The current plant employs 12 full time employees and 12 tanker trucks serve the plant every hours. The plant expansion is expected to add 5 full-time employees to the plant and will add 6 tanker trucks loading at the plant each day. These items are detailed in the traffic analysis in 11.1.D. I. A number of skid -mounted pieces of process equipment are being installed at the site. These include I- Inlet gas skid with upper and lower configuration, 1- Flash Tank Valve skid, 1- Amine Filter skid, 1- Circulation pump, 1- Reflux/Booster skid, 1- Chiller/Refrigeration skid with upper and lower configuration, 1- Stabilizer skid, 1 - Residue Gas Metering skid, 1- NGL Pump skid, 1- Glycol skid, 1- FIM© skid, 1- Fuel gas skid, I- Flare knockout skid- 80 feet tall, 4 emergency generators, 2- Refrigeration compressors, 3- NGL Storage tanks and 2- tanker loading stations. Please see the site plan for details. Three new Caterpillar 3612 residue gas compressors will be installed at the site. Room for 2 additional residue gas compressors will be included in the compressor building. The air permit issued by the Air Pollution Control Division will need to be revised prior to startup of the new compressors. Residential Grade exhaust silencers will be installed on the compressors and the compressors will be enclosed by a pre-engineered steel building. Electrical power is currently being upgraded to the existing Parachute Creek Gas Plant and will be completed in September 2004. This electrical upgrade has been sized to serve the plant expansion as well. Construction Schedule: A. Overlot grading of the site occurred in July 2004. B. Steel piling installation is anticipated to occur in August/September 2004. Page 2 of 5 • • • • C. Equipment foundations are anticipated to be poured in OctoberfNovember 2004. D. Piping, equipment installation and other associated work will occur from October 2004 through February 2005, E. Building foundations and building erection will occur after approval of the special use permit. F. Plant startup is scheduled for March 2005. Williams Production RMT Co. has agreed to move forward with piping and equipment installation "at their own risk" as the Garfield County Special Use Permit for the proposed plant has not been granted. Please find attached pictures of the existing Parachute Creek Gas Plant and the surrounding area. 2, Existing zoning: The proposed plant expansion area is Resource Lands- Lower Valley Floor. The Garfield County Zoning Resolution Section 3,10 04 notes "Resource Lands- Gentle Slopes and Lower Valley Floor. Uses, special: allowed by permit only: Industrial support facilities which would include: material handling, pumping facilities, electric distribution, warehouse facilitieslstaging areas, water impoundments, access routes, utility lines, utility substations, pipelines; extraction, processing, accessory uses to the above..." We see that the proposed Parachute Creek Gas Plant expansion meets the Garfield County Resource Lands- Gentle Slopes and Lower Valley Floor special use permit designations 3. Surrounding zoning: Resource Lands and the existing uses are Industrial and Agricultural. 4. Garfield County Comprehensive Plan of 2000: The Garfield County Comprehensive Plan of 2000 notes this project in Study Area 3. Natural Resource extraction is detailed in Section 9 of the "Goals, Objectives, Policies and Programs" located on page 17. "Garfield County recognizes that under Colorado Law, the surface and mineral right interests have certain Iegal rights and privileges, including the right to extract and develop these interests. Furthermore, private property owners also have certain legal rights and privileges, including the right to have the mineral estate developed in a reasonable manner and to have adverse land use impacts mitigated." Policies Section 9.1 notes: "Garfield County, to the extent legally possible, will require adequate mitigation to address the impacts of mineral extraction on adjacent landowners. These measures may include the following: Page 3 of 5 • • • A. Landscaping and screening; B. Modification of phasing or area to be mined, C. Roadway improvements and signage, D. Safe and efficient access routes; E. Drainage improvements to protect surface and groundwater" We see that the proposed Parachute Creek Gas Plant expansion meets the Garfield County comprehensive plan goals, objectives, policies and programs. We have addressed each of the policies stated in 9.1. Additionally, the Parachute Creek Gas Plant permitting in June 2002 and the functioning of the plant over the last 2 years has demonstrated compliance with the Garfield County Comprehensive Plan. 5.

Fourteen people are currently employed at the plant. A proposed addition to the property structure will result in the employment of five additional employees resulting in a total of 19 people at the facility. The existing individual sewage disposal system (ISDS) at the site has been designed for a maximum of 20 people under an estimated sewage loading of 15 gallons/person-day (average flow). Under the ISDS design loading of 15 gallons/person-day, the 19 person facility will utilize an average of 285 gallons/day (i.e., 19x15 = 285). Under this water use scenario, the 1,000 gallon cistern will need to be filled every 3 to 4 days. Current water use records for the existing 14 person facility indicate that filling the cistern once weekly is sufficient to meet the existing nonpotable water use needs. Existing water use records support the conclusion that actual water use is indeed lower than the ISDS design loading criterial of 15 gallons/person-day (i.e., 14 gallons/person-day for 5 day week and 10 gallon/person-day for 7 day week). As based on the above discussion, it is reasonable to conclude the existing 1,000 gallon cistern will need to be filled once or twice per week to supply the nonpotable water supply need for the proposed 19 person facility.

The site has been construction -leveled in the area of reference. A percolation test/soils evaluation was conducted on the property of reference on 06/25102 by an agent of Torn A. Crank, registered professional engineer (R.P.E.). The 06/25102 site investigation was intended to provide subsurface design parameters for a new individual sewage disposal system (ISDS) to serve a commercial office at the site, An engineered ISDS design based on results from the 06/25/02 study has been prepared for the property, The 06/25/02 site investigation report is attached for reference as Appendix A. The locations of the perc excavations are shown on the attached plot plan. A discussion of developed design parameters and the engineered design follow. 2.0 Development of Design Parameters A pert excavation trench (excavation A) was extended to a depth of 120" below ground surface (BGS). There was no evidence of ground water in the open excavation to a depth of 120" BGS. The high seasonal water table was estimated at a depth of 100" BGS. The soils evaluation indicates two distinct soil horizons underlie the site. A Ethological description follows: depth (in.) description 0" - 76" mixture of line sand, silt, coarse to small sandstone cobbles with lenses of sandstone chips 76" - 120" silty clay As based on the 06/25/02 site investigation (Appendix A), a design perc rate of 80 min/in. is chosen for overall system sizing. Page 2 of 9 3.0 System Design A trench absorption field is proposed for discharge of septic effluent at the site. As shown in the attached graphics, the absorption field will consist of four trenches 2' wide and 51' Iong. The trenches will be excavated to a depth of 48". After excavation, 36" of gravel fill (1.0"-2.5" screened rock with aggregate components of uniform size) will be used to construct a level seepage bed in each trench. Adjacent trenches shall be separated by a minimum horizontal distance of 6' (10'-12' separation recommended for ease of construction) of undisturbed soil. Septic effluent distribution piping in the absorption field will consist of a 4" perforated discharge line placed level (end-to-end) down the center of each trench. As shown in the attached graphic, the perforated line will terminate 18" from the ends of each trench. The perforated line will be embedded in the gravel seepage fill with a minimum of 30" of gravel under, and 2" of gravel over each pipe. Ends of the perforated line will be looped with solid piping to adjacent trenches. As shown in the attached graphics, septic effluent will be delivered from the septic tank to each of the four trenches through a distribution box to provide equal distribution. The distribution box must be placed on stable native soil or compacted structural fill to prevent settling and assure equal distribution of septic effluent. Native soil will be used to filI the remaining 12" of trench excavation and construct a soil cap over the absorption field. Before placing the soil cap, synthetic filter fabric ("myrafi", 140-200 mesh), hay, or untreated building paper will be placed over the gravel bed to prevent intrusion of fine soils. The native soil backfill will be mounded 5% over each trench to promote surface flow runoff in the vicinity of the absorption system. The installer should confirm the feasibility of gravity discharge of sewage effluent from the existing septic tank 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 - 200' or less, • elevation of the ground surface at entry to the absorption field shall be at least 30" below 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 office 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. Four inch clean outs shall be installed at maximum 100' intervals in all effluent lines exceeding 100' in length. The ISDS will be sized for sewage flows from a 1350 sq. ft. office (14 person). Average sewage flow from a 14 person office is estimated at 15 gal/employee-8 hr shift or 210 gallday average total flow. The allow for future expansion, the ISDS will be sized to handle an average daily sewage loading of 300 Page 3 of 9 gal/day. A 1,000 gallon septic tank is required for septic effluent discharged at the design daily flow rate. A non - corrodible filter shall be installed at the final outlet Tee of the septic tank or in the effluent line between the septic tank and the absorption field to limit the size of solids and sludge passing into the absorption field. The filter must be accessible for cleaning and replacement from the ground surface. A distribution box is required to provide equal distribution of septic effluent from the septic tank to the absorption field. The distribution box must be placed on stable native soil or compacted structural fill to prevent settling and assure equal distribution of septic effluent As discussed above, a trench absorption field is proposed to discharge septic effluent to the underlying sub -soils. As shown in the attached graphics, the absorption field will consist of four trenches, each 2 ft wide, 48 in. deep, and 51 ft long. The trenches will be filled with 36" of gravel to provide an effective infiltration area of 815 square feet. 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' occupied bldng 5' 20' property Pines 10' 10' subsoil drains 10' 25' irrigation ditch open 50' 50' lined/gated 25 25' solid pipe 10' 10' • To avoid surface flow infiltration and saturation of the new absorption system, abandonment of irrigation in the vicinity of the disposal system is required. Diversion ditches necessary to divert surface flows around the new absorption bed must maintain the minimum setbacks listed above. • All sewer lines and effluent distribution piping shall be 4 inches in diameter, have glued joints, and shall be looped at termination of discharge. Septic tank effluent lines shall be placed level in the absorption field. AlI lines discharging sewage from the office 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 office 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 when covered with less than 24" of soil. Page 6 of 9 • • • 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. • Four inch clean outs shall be installed at maximum 100' intervals in all effluent lines exceeding 100' in length. • A non -corrodible filter shall be installed at the final outlet Tee of the septic tank or in the effluent line between the septic tank and the absorption field to limit the size of solids and sludge passing into the absorption field. The filter must be accessible for cleaning and replacement from the ground surface. • The distribution box shall be set level on undisturbed native soil or a structural pad (e.g., compacted fall or concrete) to prevent settling and promote uniform distribution of flow to the absorption field. A 45 degree bend shall be turned down on the septic influent line to damp surge flows from the septic tank and promote equal distribution. • The seepage trenches shall be constructed with a 36 in. layer of 1.0 in. to 2.5 in. screened rock spread evenly over each trench. The effluent distribution lines will be placed level in the seepage beds with 30" of gravel under, and 2" of gravel over each line. A covering of untreated building paper, hay, straw, or synthetic filter fabric (e.g., "myraf", 140-200 mesh) shall be placed on top of the gravel absorption trenches before placing the surface cap. The surface cap shall be mounded 5% over the absorption trenches 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: i. Excavation should proceed only when the moisture content of the soil is below the plastic limit. Lf 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. ii. 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 septic effluent filter shall be inspected and cleaned as necessary every six (6) months. • 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.

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 52" BGS to maintain 4' of usable infiltration soil above the HSWT located at 100" BGS. A design perc rate of 80 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. Page A-2 of A-3 3.0 Limitations This report provides a professional assessment of the feasibility of implementing an individual sewage disposal system on the property of reference. The design parameters developed in this document are representative of the site conditions disclosed at the specific time of the site investigation. Site conditions are subject to change from external events both manmade (irrigation or pond construction) and naturally occurring (flooding or excessive precipitation). Cronk Construction Incorporated is not responsible and accepts no liability for any variation in assumed design parameters caused by external events. Cronk Construction Incorporated represents this report has been prepared within the Limits prescribed by the owner and in accordance with the current accepted practice of the civil engineering profession in the area. No warranty or representation either expressed or implied is included or intended in this report or in any of our contracts. SEAL Page A-3 of A-3 (ZD Thomas A.

Garfield County Road and Bridge Department Access Issues I met Kraig Kuberry and Marvin Stephens on August 3, 2004 at the intersection of County Road #215 and Man Camp Road. There is an existing Garfield County Access permit for the intersection. The attached map dated 8/25/04 by Construction Surveys details the improvements to be made at the intersection. All of the improvements shown on the plan regarding signage such as installation of 2 new "Do Not Enter Signs", installation of the delineator post and installation of 2 plant directional signs will occur upon approval of the special use permit. Improvements regarding striping of the acceleration and deceleration lanes at the southwest side of County Road #215 will occur as the weather permits in Spring 2005. All of the costs of the improvements as shown on the plan will be paid for by Williams Production RMT Co. The above information illustrates that the existing intersection with some striping and signage improvements provides the safety necessary to serve the plant expansion and other traffic on County Road #215.. The traffic counts and traffic study are attached and shown on 12.1.D.1. Please contact me with any questions.

Union 76 Water Well Nos. 6 and 6A were also adjudicated as alternate points of diversion for water rights of the Pumping Pipeline of Union Oil Company of California in a decree of the District Court in and for Water Division No. 5, State of Colorado in Case No. 81CW319 on May 5, 1983. The conveyance of Union 75 Water Well Nos. 6 and 6A and the water rights described above includes no interest in the Pumping Pipeline water rights and no interest in any other water rights involved in Case No. 81 CW319. Unocal mares no representation or warranty concerning the amount of water that may be available in priority to the wells under the water rights adjudicated in Case No. 82CW433. Pursuant to the decree in Case No. 82CW433, the pumping rate of Union 76 Water Well Nos. 6 and 6A, combined with that of Union 76 Water Well Nos. 2, 3, 4 and 5, was limited to 1000 gpm. Union 76 Water Well Nos. 2, 3, 4 and 5 have decreed priorities senior to that of Union 76 Water Well Nos. 6 and 6A. Consequently, the pumping from Union 76 Water Well Nos. 6 and 6A may be limited if the total pumping, when combined with that of Union 76 Water Well Nos. 2, 3, 4 and 5, would exceed 1000 gallons per minute. Interest in Irrigation Ditches and Related Easements The subject property was historically irrigated with diversions from the following ditches: 1.

Name: Title: Telephone Number: Signature: Date: Parachute Creek Gas Plant CordiJleran Compliance Services. Inc. Construction Stormwater Management Plan Grand Junction, Colorado EXECUTIVE SUMMARY Purpose/Objective Cordilleran Compliance Services, Inc. (Cordilleran) has prepared this Stormwater Management Plan (SWMP) for Williams Production. RMT Company (Williams) for construction activities associated with the Parachute Creek Gas Plant in Garfield County, Colorado. According to the Colorado Department of Public Health and Environment (CDPHE) regulations, construction sites disturbing more than five acres of land are required to prepare a stormwater management plan. The goal of this plan is to improve water quality by reducing pollutants in stormwater discharges. Construction activities potentially produce many different kinds of pollutants that may adversely impact stormwater. The main pollutant of concern at construction sites is sediment, which can become entrained in stormwater runoff following grading activities that remove protective vegetative cover. When the stormwater runoff carrying these sediments reaches a lake or stream and slows down, the suspended sediments are deposited, and can choke the river channel or cover areas where fish spawn and aquatic plants grow. The particles also cloud waters causing aquatic respiration problems resulting in the death of fish and plants in these systems. Construction may also involve the use of toxic or hazardous materials such as petroleum products, fertilizers, pesticides and herbicides, and building materials such as sealants and concrete, and other chemicals that can be harmful to humans and aquatic life. This plan covers the plant site and the associated right-of-way. Cordilleran has prepared this plan for Williams in order to satisfy the stormwater management requirements for a new construction site. This SWMP for the Parachute Creek Gas Plant will be maintained at the Parachute Creek Gas Plant, at the Williams Parachute Office, and at the Williams regional office in Denver, Colorado until the stormwater discharge permit expires or is inactivated by Williams. Facility Name/Location The Parachute Creek Gas Plant site is located approximately 4 miles northwest of the town of Parachute, Colorado on County Road 215 in Garfield County, Colorado. The site lies within the northeast quarter of the northeast quarter of Section 33, Township 6 South, Range 96 West. Specifically, the site is located at 39'29'13" north latitude, and 108°6'31" west longitude. Refer to the site location map in Figure 1.

Natural gas enters the station via a gathering system pipeline supplied by local production fields. The quality of the natural gas is improved by removing the water, natural gas liquids, and carbon dioxide from the gas stream to make it suitable for pipeline transport. This facility operates 24 hours per day, 365 days per year and employs 18 full time employees. Parachute Creek Gas Plant 2 Cordilleran Compliance Services, Inc. Construction Stormwater Management Pian Grand Junction, Colorado • • 1.0 INDUSTRIAL ACTIVITY DESCRIPTION 1.1 Site Location The Parachute Creek Gas Plant is located approximately 4 miles northwest of the town of Parachute, Colorado on County Road 215 in Garfield County, Colorado. The facility lies within the northeast quarter of the northeast quarter of Section 33, Township 6 South, Range 96 West. Specifically, the site is located at 39°29'13" north latitude, and 108°6'31" west longitude. Refer to the site location map in Figure 1. 1.2 Site Description The Parachute Creek Gas Plant site is located in an arid region on the western slope of Colorado. According to information from the National Oceanic and Atmospheric Administration (NOAA) Western Regional Climate Center, the area receives an average of between 10 and 15 inches of precipitation annually. The maximum estimated precipitation in a 24 hour period, for a 25 year storm event is 21 tenths of an inch (2.1 inches). According to information from the USDA Natural Resources Conservation Service, soils in the vicinity of the Parachute Creek Gas Plant belong to the Arvada-Torrifluvents-Heldt complex. These soils are deep, well drained to somewhat poorly drained, nearly level to gently sloping soils, on benches, terraces, alluvial fans, and flood plains. Runoff is very rapid and the hazard of water erosion is very high. Parachute Creek, a perennial stream, is located approximately 750 feet southwest and down gradient of the Parachute Creek Gas Plant site. Parachute Creek flows southeast to its confluence with the Colorado River, approximately 3.8 miles southeast of the plant location. There is also an irrigation drainage ditch, which flows intermittently, approximately 150 feet north and up gradient of the site. 1.3 Process Description The Parachute Creek Gas Plant is a natural gas fractionation processing and dehydration facility. As a construction site that will disrupt more than 5 acres of land, the primary concern is that of sediments becoming entrained in stormwater and flowing offsite following grading and clearing operations. Additionally, any chemicals stored or used onsite during construction have the potential to adversely impact stormwater and migrate offsite without proper management in the event of a spill or release. The Parachute Creek Gas Plant is currently operational at the date of this revision. The overall facility process will involve receiving gas from area gathering systems and sending it into two separate processes where water, natural gas liquids, and carbon dioxide (CO2) are removed. The current design capacity of the facility is 120,000,000 standard cubic feet of natural gas per day (MMSCFD), however, the planned expansion will increase this capacity. The water and natural gas liquids are transported offsite by truck, while carbon dioxide is vented to atmosphere. Parachute Creek Gas Plant 3 Cordilleran Compliance Services, Inc. Construction Stormwater Management Pian Grand Junction, Colorado • • • L4 Major Equipment Heavy machinery will be used during the expansion of the plant to clear and grade the surface of the site to make it suitable for construction activities. Heavy machinery will move additional processing components to the site and will be used to assemble them once onsite. In general, the major equipment to be installed at the site during the expansion includes heat exchangers, condensers, boilers, coolers, filters, heaters, separators, contactors, dehydrators, scrubbers, natural gas compressor engines,and pumps. Storage tanks for new and used chemicals and for condensate and produced water are currently located onsite and may be supplemented with additional storage tanks. Parachute Creek Gas Plant 4 Cordilleran Compliance Services. Inc. Construction Stormwater Management Plan Grand Junction, Colorado • • 2.0 SITE DESCRIPTION The Parachute Creek Gas Plant site currently occupies approximately 10.1 acres and has a slight slope to the south-southwest. The change in elevation across the existing site from the north to the south is approximately 40 feet. The north plant expansion area will occupy approximately 10.3 acres and the change in elevation across this portion is approximately 30 feet. Stormwater runoff from the site tends to flow toward Parachute Creek, a perennial tributary to the Colorado River. Stormwater outfalls, surface water, structural control measures, industrial activities, materials handling, loading, and storage areas, and adjacent properties are described in the following sections. 2.1 Location of Stormwater Outfalls In considering the Location and planned plot area of the new construction area at the Parachute Creek Gas Plant, stormwater outfalls are anticipated to remain along the southwest border of the property. Stormwater leaves the Parachute Creek Gas Plant site via surface flow to the southeast. Currently no stormwater outfalls exist onsite; instead stormwater exits the site via sheet wash. 2.2 Drainage Basins for Each Outfall Stormwater runoff generally moves to the south and southwest across the site. During construction, the plant should have a silt fence constructed around the southern and western boundaries to prevent soils from washing offsite. Once the plant is constructed the drainage basin areas for each stormwater outfall should be calculated. In the event that the Parachute Creek Gas Plant has a release or spill of a reportable quantity that impacts stormwater and migrates offsite this SWIM should be revised and submitted to the Colorado Oil and Gas Conservation Commission (COGCC) and CDPHE. 2.3 Surface Water/Dry Water Courses Parachute Creek, a perennial stream, is located approximately 750 feet southwest and down gradient of the Parachute Creek Gas Plant site. Parachute Creek flows southeast to its confluence with the Colorado River, approximately 3.8 miles southeast of the plant location. There is also an irrigation drainage ditch, which flows intermittently, approximately 150 feet north and up gradient of the site. 2.4 Existing Structural Control Measures to Reduce Stormwater Pollution There are no existing stormwater controls to consider for the development of stormwater management practices to be used during construction. The stormwater outfalls at the plant should inspected often during construction and be maintained with landscape fabric, rip rap, concrete, straw bales or other energy dissipating Parachute Creek Gas Plant 5 Cordllleran Compliance Services, Inc. Construction Stormwater Management Plan Grand Junciion, Colorado • • devices to prevent erosion. Stormwater conveyances need to be maintained and clear of debris and vegetation in order to adequately handle stormwater from the site. 2.5 Construction Activities The Parachute Creek Gas Plant is used for the purpose of removing carbon dioxide, nitrogen, and water vapor from the natural gas prior to custody transfer of the natural gas for transport to' market. The Parachute Creek Gas Plant stores natural gas condensate, produced water, and bulk chemicals such as lubrication oil for the natural gas compressor engines and the new and used diglycol amine used in the carbon dioxide removal processes. The facility is classified as a Tight industrial site. with a North American Industry Classification System (NAICS) number of 211112. Natural gas enters the plant via pipelines, is processed and is transported via pipeline from the facility. The Parachute Creek Gas Plant is also a sales point at which the custody of the gas is transferred to Northwest Pipeline on the southeast corner of the Parachute Creek Gas Plant. 2.6 Materials Handling, Loading, and Storage Areas Fuels, pesticides or herbicides, paints or solvents. and other industrial materials associated with construction activities must be handled, loaded, and stored so as to prevent stormwater impacts from occurring. All liquids shall be stored in appropriate containers and properly protected from adverse weather or storm events. By following good housekeeping and best management practices (MMPs), discharges of impacted stormwater can be averted. Industrial wastewater shall be properly disposed and not allowed to be discharged to stormwater conveyances. 2.7 Adjacent Property Descriptions The site is surrounded on all sides by private agricultural land. Surrounding land usage is primarily for oil and gas exploration and production and to a lesser extent for seasonal livestock grazing and farming.

Construction Stormwatcr Management Plan Grand Junction, Colorado • • 3.0 DESCRIPTION OF POTENTIAL POLLUTION SOURCES AND MATERIAL INVENTORY The following is a description of potential sources of pollutants to stormwater discharges. 3.1 Description of Significant Material Storage During construction chemical storage will be minimal. Stockpiles of excavated soils should be bermed and covered with sheet plastic or tarps to prevent stormwater from transporting sediments into nearby dry washes. Any fuel storage tanks for trucks and heavy construction equipment refueling should be contained in an earthen berm capable of containing the entire volume of the largest tank. 3.2 Description of Significant Spills. Leaks, Releases The expansion area of the Parachute Creek Gas Plant has no record of prior development. No significant spills, leaks, or releases have occurred at the site prior to initiation of construction activities in June 2002. 3.3 Description of Stormwater Discharges An active CDPHE stormwater discharge permit for construction activities with permit number COR — 034248 exists for the Parachute Creek Gas Plant at the time of this revision. 3.4 Potential Pollution Sources Potential pollution sources during construction may include graded soils cleared of native vegetation, excavated soil stockpiles, aggregate stockpiles, vehicle fuel tanks and oil dripslleaks, fuel ASTs, use of pesticides and herbicides, and use of sealants, emulsions, or concrete. Engineering controls should be used to control soil erosion. Chemicals should be properly stored in areas where they will not come in contact with stormwater. 3.5 Summary of Stormwater Sampling Data Stormwater sampling is not required by the discharge permit issued for the facility and sampling has not been requested by the CDPHE.

These are described below. 4.1 SWMP Administrator The SWMP Administrator is responsible for: Authority for dedicating the necessary financial and human resources to implement the SWMP; - Implementing spill clean ups; Notifying local authorities and local residents in the event that a significant release of stormwater occurs that leaves the plant; and - Signatory authority. - Coordinating various stages of plan development and implementation: - Conducting inspections; Coordinating employee training programs; Maintaining all records; - Making certain that all appropriate reports are submitted as necessary; - Coordinating the implementation of the preventive maintenance program; and - Supervising spill response and housekeeping measures. 4.2 Preventive Maintenance The following preventive maintenance measures will be implemented to reduce potential stormwater contamination sources at the Parachute Creek Gas Plant: Storage containers, fuel tanks, and equipment in use during construction activities will be visually inspected daily for obvious leaks by site and contractor personnel as they perform their routine duties; Storage containers will be properly labeled so material accidentally released can be quickly identified, properly cleaned up, and disposed. OSHA -approved labeling and signage systems will be completed in a timely fashion; Erosion damage to the earthen berms and outfalls onsite will be repaired in a timely fashion; Areas of stained soil will be inspected to identify the sources, and if necessary, releases associated with routine operations and maintenance will be minimized to the extent practical; - Energy -dissipating material, such as riprap, will be placed at the stormwater outfalls to prevent erosional damage. Although the site does not currently have distinct outfalls, energy -dissipating material such as cobbles or gravel could minimize erosion of onsite soils at the outfalls and in areas where chemicals are likely to come into contact with stormwater. Barrow ditches should be free from vegetation and debris which may cause impounding of stormwater;. Parachute Creek Gas Plant 8 Cordilleran Compliance Services. Inc. Construction Stormwater Management Plan Grand Junction, Colorado Stormwater management structures will be cleared of debris and repaired when necessary; and Surface runoff controls such as curbing, culverting, and ditches will be used to control runoff at the facility, and will be used to prevent runoff from the adjacent properties to the north from flowing onto the facility. 4.3 Good Housekeeping The following items will be addressed to maintain a clean and orderly facility. 4.3.1 Operations and Maintenance Techniques Develop and maintain inspection schedules (See Attachment A); Correct deficiencies noted during these inspections; - Clean and maintain stormwater management system components; Routine trash collection and disposal, and grounds maintenance; Familiarize employees and contractors with the storage locations for spill clean-up equipment; Familiarize employees and contractors with good housekeeping procedures, tips, reminders, and pollution prevention concepts; and Control erosion around vehicle access areas (gravel drive-through areas). 4.3.2 Material Storage and Inventory The following good housekeeping practices will be followed at the material storage areas: - Storage containers will be stored away from direct traffic to prevent accidents; Dumpsters, empty containers, receptacles, and sumps will be covered to prevent the collection of precipitation; Storage areas will be kept free of trash; Chemical substances used at the site will be identified, properly labeled, inventoried, and the Material Safety Data Sheets (MSDS) will be kept on file; Chemical substance containers will be clearly labeled and have MSDS on file. The following information should be displayed: o Type of substance. o Stock number. o Expiration date. o Reactivity. o Corrosivity. o Ignitability. o Toxicity. o Health hazards. o Suggested hauling methods. o First aid. Containers will be stored off the ground to prevent corrosion. Parachute Creek Gas Plant 9 Cordilleran Compliance Services. Inc. Construction Stormwater Management Plan GrandJu►tcrion, Colorado • • • 4.4 5_0ll Prevention and Response Procedures Williams is committed to operating the Parachute Creek Gas Plant in accordance with Section 112.7 of the Oil Pollution Prevention Regulations issued under the Federal Water Pollution Control Act (40 CFR Part 112). These regulations require the owners/operators of certain facilities to prepare and implement a Spill Prevention Control and Countermeasure (SPCC) plan. Copies of the SPCC and SWMP plans will be maintained at the Parachute Creek Gas Plant, at the Parachute Field Office, and at the regional office in Denver, Colorado. The SPCC plan contains information on the potential for oil, as defined in 40 CFR Part 112.2, to impact stormwater discharges, and the quantities of oil that potentially could be discharged. The SPCC plan contains information on employee training pertaining to spill prevention and response. Governmental agencies to be contacted in the event of a release and spill cleanup contractors are listed in Tables 2 and Table 3, respectively. 4.5 Best Management Practices Williams will continue to implement appropriate stormwater management practices including diversion: materials handling and spill prevention; sediment and erosion prevention; inspections; and other non-structural measures at the Parachute Creek Gas Plant. These are discussed below. All excavation work shall be conducted in an manner that preserves soil and allows for segregation of soil types in order to facilitate land reclamation in the future. Measures shall be taken to preserve excessive soil erosion by wind or water including silt fencing, straw bales and other stormwater management efforts. All excavated surfaces shall be maintained with adequate moisture to prevent wind erosion. 4.5.1 Stormwater Diversion Culverts may be used to control runoff or divert it away from construction activities and. equipment. Prevent stormwater flow from leaving the plant using grading or extending terraces across to the southwestern portion of the site and planting open areas with native grasses as soon as feasible. 4.5.2 Materials Handling and Spill Prevention Where possible, materials will be stored and handled in covered areas to prevent contact with stormwater. Employees and contractors will receive training in identifying spills, and in containment and cleanup measures. Training will be provided for specific material handling procedures and practices, as well as the equipment used to mitigate spills. Parachute Creek Gas Plant 10 Cordilleran Compliance Services, Inc. Construction Stormwater Management Plan Grand Junction, Colorado 4.5.3 Sediment and Erosion Prevention Energy dissipating material, such as riprap, will be placed at stormwater outfalls to prevent erosional damage; - Culverts will be cleared of debris and repairs made when necessary; - Gravel will be maintained at vehicle access areas. 4.5.4 Other Pollution Prevention Measures Good Housekeeping o Remove trash and debris from site. o Keep dumpsters or other trash receptacles covered. Record Keeping and Reporting o Records will be maintained of site inspections, spills, and stormwater control structure maintenance activities. o If a reportable impacted stormwater release occurs, a report will be submitted to CDPI-IE, Water Quality Division, and the COGCC. o Records and reports will be retained at the Parachute Creek Gas Plant for at least three years. 4.6 Employee Training Williams will continue to implement a training program to address the areas of concern outlined in the SWMP for the construction of the Parachute Creek Gas Plant. Personal work responsibilities are used to identify the appropriate attendees. The training program will be conducted along with standard safety and environmental training. The following topics are included in the SWMP training program. 4.6.1 Introduction to Stormwater Permits Stormwater regulations; Purpose of stormwater permit; and Requirements of stormwater permit. 4.6.2 Pertinent Components of the Permit - SWMP Spill response and clean-up procedures: - Clearly identify potential spill areas and drainage routes. Make employees aware of the materials handled, where those materials are used. and how materials are to be handled, Identify labels and location of Material Safety Data Sheets.. Discuss the environmental impact of potential spills. Make emergency contacts and telephone numbers readily available. Parachute Creek Gas Plant 1 1 Cordilleran Compliance Services, Inc. Construction Stormwater Management Plan Grand Junction, Colorado • • Make certain employees know the locations of spill response equipment. [)rill employees on spill cleanup procedures. Good housekeeping procedures - Review and demonstrate basic cleanup procedures. Identify proper disposal methods and locations. Best Management Practices Review use of berms, grading, gravel, etc. for erosion control to avoid sedimentation. Process evaluation to evaluate procedural and equipment improvements that can cost effectively reduce the potential for chemicals to come in contact with stormwater or reduce a potential for an impacted storm release. Inspections - Discuss routine inspection methods and responsibilities. 4.6.3 Reporting and Record keeping Review and demonstrate inspection reporting and record keeping procedures including appropriate forms and tables (Attachment A). 4.6.4 Enforcement Discuss Williams commitment to enforcement of the various components of the SWMP. 4.7 Record keeping for Non-Stormwater Discharges Stormwater leaves the Parachute Creek Gas Plant site along the ground surface via drainage swales and culverts, not through sewers or other buried piping; therefore, non-stormwater discharges are very unlikely to occur. However, dry weather inspection of stormwater discharge outfalls will be conducted as part of the regular stormwater management system inspections to make certain that non -permitted discharges are not included in permitted discharge. Results of the non-stormwater discharge inspections will be recorded on the worksheet provided in the SWMP Logbook (see Attachment A), which will be kept on file at the Parachute Creek Gas Plant. Parachute Creek Gas Plant 12 Cordilleran Compliance Services. Inc. Construction Stormwater Management Plan Grand Junction Colorado • • 5.0 RECORD KEEPING AND INTERNAL REPORTING PROCEDURES The following procedures for record keeping and internal reporting will be followed to keep accurate and complete documentation of events associated with the stormwater management program. A SWMP Logbook will be developed for the Parachute Creek Gas Plant. Examples of the inspection checklists to be included in the logbook are presented in Attachment A. 5.1 Inspection Log The SWMP Logbook will include an Inspection Log. This will be used, when appropriate, for recording pertinent information regarding stormwater management activities. The kinds of information that will be recorded include: Observations of spills, Leaks, or overflows; the location, time, date, and weather conditions when the event occurred; and the corrective actions required and taken will be recorded; Storrnwater management and pollution prevention training activities; Contacts with regulatory agencies and personnel; and Maintenance and repair of structural storm water management controls. 6.0 CONSISTENCY WITH OTHER PLANS This SWMP has been written and revised without the preparation of a separate SPCC plan specific to construction activities. A SPCC plan for the Parachute Creek Gas Plant that complies with §112.7 of the Oil Pollution Prevention Regulation (40 CFR §112) issued under section 311 of the Federal Water Pollution Control Act has been prepared for the current operational conditions of the facility. The SPCC plan should be revised as necessary by qualified Williams personnel or by an outside party with knowledge of the facility once construction activities are complete. 7.0 ALLOWABLE NON-STORMWATER DISCHARGES No non-stormwater discharge permits have not been issued for construction of the Parachute Creek Gas Plant from CDPHE at this time. Generally, discharges are not allowed other than discharges entirely of stormwater, except if necessary, water for fire fighting activities. There are no foundations or footing drains, natural springs, or landscape irrigation return flows associated with construction of the Parachute Creek Gas Plant. 8.0 ADDITIONAL REQUIREMENTS FOR FACILITIES SUBJECT TO SARA TITLE III, SECTION 313 REQUIREMENTS The Parachute Creek Gas Plant site is not subject to SARA Title 111, Section 313 requirements because there have been no releases of reportable quantities of hazardous materials to land or water from this facility.

The Plant currently stores "oil- (as defined by the EPA) in quantities sufficient to require SPCC compliance. The SPCC regulations are in place in order to minimize the risk of "oil" contamination to navigable waters and other environmental receptors. An expansion of the Plant is presently underway. This expansion includes the addition and/or modification of structures and equipment that will materially affect the storage of oil at the facility. Williams will continue to comply with all applicable SPCC requirements as required by the EPA. Toward this end, Williams has contracted Cordilleran Compliance Services, Inc. (Cordilleran) to revise the current SPCC Plan for the Plant, as the expansion progresses. Upon completion of the expansion project, Cordilleran will promptly inspect the facility and the surrounding area for compliance. Based upon this inspection and review of Plant operating. procedures, Cordilleran will, using sound engineering judgment., amend the current SPCC Plan describing best management practices designed to minimize the risk of "oil" spills and releases from occurring at the Plant. Additionally, the SPCC Plan will certify that the containment structures at the plant meet SPCC guidelines. Should you have any questions or concerns, please coptame at (970) 263-7800.

The facility consists of heat exchangers, condensers, boilers, metering equipment, dehydrationlprocessing equipment, reciprocating compressors and engines, storage tanks and vessels, and piping systems. Products related to the maintenance and operation of the facility arc stored in above ground storage tanks. Natural gas liquids (NGLs) are tricked from the facility on a regular basis. The facility is operated and manned 24 hours per day, 365 days per year. 2.4 Facility Storage Oil, as defined in 40 CFR 112.2, is stored in several above ground storage tanks (ASTs) and partially buried storage tanks al the facility. An inventory of the materials stored at the facility is presented in Table 1 in Appendix B. The locations of the tanks and storage units listed in Table 1 may be found on the Site Map, Figure 2 in Appendix A. 4 • • • The stored liquid levels are typically gauged or noted daily by Williams field personnel. The level in each tank is managed to maintain at least 3 days of excess capacity for the event in which weather or transport capacity prevents routine condensate or produced water hauling. The capacity of the containment areas will be maintained to contain the volume of the tanks above the containment structure height. Several of the tanks are enclosed in secondary containment areas, the dimensions of which are detailed in the Secondary Containment Volume Calculations table. An additional freeboard volume of approximately ten percent of the largest tank volume will be maintained to contain precipitation expected from the average annual maximum precipitation event. 2.5 Facility Drainage and Distance to Navigable Waters The closest water body to the facility is Parachute Creek, which is several hundred yards southwest of the property. All existing drainages in the vicinity of the facility discharge to Parachute Creek during significant storm events. Drainage within the site is governed by surface topography. Downhill slope direction arrows on Figure 2 indicate the predicted direction of storm water flow from the site to the south and west. SECTION 3.0 SPILL HISTORY [40 CFR 112.7(a)] The facility was not in existence and therefore did not experience a reportable oil spill event within 12 months prior to the effective date of 40 CFR 112 (January 10, 1973). • • SECTION 4.0 PREDICTION OF DIRECTION, RATE OF FLOW, AND POTENTIAL QUANTITY OF DISCHARGE [40 CFR 112.7(b)] An inventory of the materials at the facility that are regulated under this SPCC plan is presented in Table 1.

Containment capacity calculations and/or specifications are provided in Appendix B of this SPCC plan. 5.2 Conformance with Other Applicable Guidelines [4{1 CFR 112.7(e)1 The following subsections contain information relevant to the applicable sections of Part 112.7. 5.2.1 Onshore Production Facility Drainage 140 CFR 112.7(c)(5)(ii)1 Drainage from diked storage areas: Secondary containment structures at the facility are not equipped with drainage valves. Precipitation that may accumulate in the containment areas is normally allowed to evaporate. No permanent automatic pumps or ejector devices are present in any of the containment areas. 1f removal of any water accumulated in the containment areas is necessary, it will be conducted under the direct supervision of responsible personnel as described in this section. Inspection offacility structures: All field drainage or diversion systems 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 from these areas promptly upon discovery. Diked area inspection and drainage of rainwater: Accumulated precipitation is removed from all secondary containment areas 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 visually inspect the water in the containment structure and note the appearance of the water in the Secondary Containment Drainage Log included in Appendix D of this SPCC plan. This log is also used to record the name of the person draining the containment as well as the date, time. and approximate quantity of water removed DO WE REALLY HAVE TO KEEP LOGS FOR THIS?. Completed Secondary Containment Drainage Logs will be kept on file with the SPCC documents for a period of al least three years. 5.12 Production Facility Bulk Storage Tanks[40 CFR 112.7(c)(5)(lii)1 Tank cortrpatibility with its contents: Materials used for all storage tanks are compatible with the material stored and the conditions of storage.

This guide provides procedures for initial actions, and for classifying, reporting, and cleaning up spills. INITIAL ACTIONS Regardless of type, size, or location of a spill, the following initial actions should be taken: Take steps to eliminate the source of the spill and contain it, if it appears that help will be necessary to control the spill, calls for assistance should be made before engaging in spill control activities. Determine the type of material spilled. Estimate the quantity released Determine the spill location Determine preliminary impacts As soon as doing so will not jeopardize the spill control activities, contact the Production Supervisor (Kent Evers: 970-285-9377), Production/Pipeline Superintendent (Brad Moss: 970-285-9377), or the District Manager (Steven Soychak: 970-285-9377) and provide the information listed above. Once the above information is in hand, a determination of subsequent requirements will be made using the criteria described in the following sections. The Production Supervisor will respond to the situation to the extent of his capacity utilizing the help of the Operations and Principal Environmental Specialist (Dave Cesark 970-285-9377). All spills which require notification of a regulatory agency should be reported to the District Manager and the Principal Environmental Specialist as soon as possible. The District Manager or the Principal Environmental Specialist will notify regulatory agencies as appropriate. The Spill Report Form, included in this appendix, should be completed to aid future decisions. This form has prompts for all of the information that is required to evaluate the spill and for information typically required by regulatory agencies. The "Report of Undesirable Event" form, following this guide, should be used when Federal lands or Federal minerals are involved. The COGCC Spill/Release Form also follows this guide. CLASSIFYING SPILLS Reporting and subsequent cleanup activity depends upon type and quantity of material spilled, the spill location, and impacts caused. The types of material that may be spilled at a Williams facility are categorized as follows: Condensate and IEP wastes. These spills include losses of condensate, produced water, drilling mud, or any mixture of the above. Refined petroleum products. Refined petroleum products include gasoline, diesel fuel, heating oils, and lubricants. Hazardous substances. Hazardous substances are defined as any substance or waste which after its release constitutes a threat to public health of welfare or aquatic or wildlife because of its quantity, concentration, chemical, corrosive, flammable, reactive, or toxic characteristics. Substances commonly used at Williams facilities that are considered hazardous materials for reporting purposes are compiled in Table El. REPORTING SPILLS In Colorado, condensate and E&P wastes are to be reported within 24 hours if the spill has entered waters of the state (any surface or groundwater) or entered navigable waters (any surface water) in sufficient quantities to cause a sheen on the water or stain on the shore. Spills less than 5 barrels that can be immediately contained and cleaned up do not need to be reported. Spills greater than 20 barrels must be reported with 24 hours. Refined petroleum releases must be reported if they have entered navigable waters or if the quantity release exceeds 25 gallons. Spills of hazardous materials must be reported if they impact navigable waters or their volume exceeds the reportable quantities in Table E 1. In general, oral or telephone reports are to be made within 24 hours. The District Manager or Principal Environmental Specialist will notify regulatory agencies as appropriate. As a practical matter, an evaluation of the specifics of each spill and a determination of reporting requirements will be made. If there is any question about reporting requirements, Williams Resources will over -report rather than under -report. Written, follow up reports are to be sent within 10 days to: Colorado Oil and Gas Conservation Commission 1120 Lincoln 4 801 Denver, Colorado 80203 (Use COGCC Spill/Release Form) Bureau of Land Management (If the release occurred on SLM lands) File an "Undesirable Event Form" with: Glenwood Springs Resource Area Office 50629 Highways 6 and 24 P.0 Box 1009 Glenwood Springs, CO 81602 If the Local Emergency Planning Commission (LEPC) was notified of the spill (in the event of a hazardous substance release) a report should also be sent to: Dale Hancock Garfield County LEPC 109 8th St., Ste. 300 Glenwood Springs, Colorado 81601 SPILL CLEANUP Once a spill has been identified and contained, the Production Supervisor will dispatch manpower and equipment necessary to properly clean up the spill. Table E2 lists approved contractors for spill containment and cleanup. Only qualified personnel with the specific necessary training will perform remedial activities. Clean up activities can vary significantly from case to case, therefore, specific direction cannot be provided in advance. In general, any free liquid present should be collected using absorbent materials or a vacuum truck rather than allowing it to infiltrate into the ground. Liquids should be collected from water surfaces. Particular attention should be paid to confining the spill to the area originally impacted. If the cleaned up material must be stored prior to final disposal, it should not be taken from the immediate area of the spill, instead, it should be placed on, and covered with plastic sheeting, and steps should taken to control potential runoff. Spilled material should be removed from drainages as soon as possible to prevent mobilization in the event of precipitation. Williams Production RMT Company may use either off-site disposal, the Williams landfarm near Parachute, or on- site land farming to accomplish cleanup. The Principal Environmental Specialist should be contacted for the location of an approved disposal Facility. As on-site land farming cannot be performed without approval of the COGCC and the landowner, the Principal Environmental Specialist should also coordinate this activity.

EXPLORATION at PRODUCTION Tower 3, Suite 1000 1515 Arapahoe Street Denver, CO 80202 3031572-3900 303/629-8255 fax The increased demand for natural gas has caused Williams Production RMT Company (Williams) to operate more drilling rigs in the Piceance Basin and, as such, gas production is expected to increase by fifty percent within the next year and by seventy-five percent within the next two years. Consequently, Williams is planning a significant expansion project for the Parachute Creek Gas Plant (PCGP) to meet the new gas processing commitment. Williams is proposing to modify the facility -wide permit to reflect the changes in operating parameters and process and control equipment associated with expansion of the plant. The current plan is for the new plant expansion to commence construction in September of 2004 with the projected startup date between March 1 and May 1 of 2005. Williams plans to increase the permitted maximum gas throughput of the plant from the existing 100 MMscf/day to a new total maximum plant throughput of 300 MMscflday with the addition of a new 200 MMscf/day gas processing skid (New Skid) and associated gas compression and gas conditioning equipment. The corresponding new emission sources associated with this plant expansion project include the following: 3 New Skid Residue Recompression Engines (Source ID: ENG -13, ENG -14, and ENG -15) 3 New Skid Propane Refrigeration Engines (Source ID: ENG -16, ENG -17, and ENG -18) 1 New Skid Process Heater (Source ID: HTR -2) 1 New Skid Amine Sweetening Unit (Source ID: AMINE -2) 1 New Skid Ethylene Glycol (EG) Dehydration Unit (Source ID: DENY -2) 1 New Skid Process and Emergency Flare (Source ID: FLARE -2) 2 New Skid Condensate Storage Tanks (manifolded single source, Source ID: TK -MX -4) 1 New Skid Condensate Loadout Emission Source (Source ID: LOAD -3) 1 New Skid NGL Loadout Emission Source (Source ID: LOAD -4) 1 New Skid Fugitive VOC Emission Source (Source ID: FUG -2) 4 Exempt Emergency Generators (Source ID: GEN -1-6) In addition to the new emission sources listed above, Williams is removing or modifying several existing sources as listed below: Remove electrical generator engines ENG -07 and ENG -0$ from permit, change to exempt emergency status, renamed to GEN -01 and GEN -02. Reduce NOx emission factor for ENG -01, ENG -02, ENG -03, ENG -09, and ENG -10 from 2.0 glbhp-hr to 1.5 g/bhp-hr, based on EPA reference test data. of) ,out • Mr. Ram Seetharam CDPHE April 30, 2004 Page 2 Revise VOC emissions from the condensate tank emission source (Source ID: TK-I/TK-2) based on a recent pressurized condensate sample analysis and E&PTANK2.O computer model. Details regarding new and modified emission sources are presented below. Compressor/Generator Engines There will be a total of 22 internal combustion engines driving gas compressors or electrical generators at the plant. Of the 12 existing or permitted engines at this facility prior to this modification, two are driving electrical generators (Source ID: ENG -7 and ENG -08). These two engines will be re -designated as exempt emergency generators because the gas plant will be operating on the grid when the draft permit for this modification issues. They will be renamed to Source ID: GEN -01 and GEN -02, and removed from the permit. Five existing engines will be permitted with slightly lower NOx emission factors (Source ID: ENG -0I, ENG -02, ENG -03, ENG -09, and ENG -10), and five will remain unchanged under this permit modification. Engines ENG -01, ENG -02, ENG -03, ENG -09, and ENG -10 are each Ajax DPC 2804 LE 2 -cycle lean burn engines site rated at 792 hp. Each of these five engines was permitted at 2.0 g/bhp-hr and 13.5 tpy NOx. Engines ENG -01, ENG -02, and ENG -03 each successfully passed USEPA reference testing on January 8 and February 18, 2003, with both measured NOx and CO emissions averaging well below the permit limits. Based on the results of the USEPA reference tests, Williams is proposing to lower the NOx emission factor and annual emission limit for each of these five Tike -kind engines from 2.0 glbhp-hr to 1.5 gibhp-hr and from 15.3 tpy NOx to 11.5 tpy NO*. Measured NOx emissions from all USEPA reference test runs for engines ENG -01, ENG - 02, and ENG -03 were below this value, and as such, Williams believes that the Division should not require that these engines be re -tested using the USEPA reference test method. Please note that all of the engines at this facility are subject to semi annual testing using a portable analyzer. Williams will install six additional compressor engines associated with the New Skid expansion. Each of the six compressor engines will be equipped with SCO catalytic control systems to meet the reciprocating internal combustion engine (RICE) MACT standard requirements. Three compressor engines (Source ID: ENG -13, ENG -14, and ENG -15) will be used for residue gas recompression to support the New Skid expansion. These engines are each Caterpillar 3612 LE TA -130 4 -cycle lean burn engines each site rated at 3,210 hp. In accordance with the RICE MACT, the SCO control system will achieve CO and VOC/HAP control efficiencies of 93%. Williams has listed the NOx, CO, and VOC/HAP emission factors and annual emission limits at 0.7 g/bhp-hr NOx, 0.18 g/bhp-hr CO and 0.1 g/bhp-hr VOC based on manufacturer's emission factors and reflecting the 93% control efficiency of the SCO control system. Williams also has similarly listed the individual and aggregate HAP emissions for these engines to reflect the 93% SCO control efficiency. Three compressor engines (Source ID: ENG -16, ENG -17, and ENG -18) will be used for propane refrigeration compression to support the New Skid expansion. These engines are each Caterpillar 3512 LE TA -130 4 -cycle lean burn engines each site rated at 777 hp. In accordance with the RICE MACT, the SCO control system will achieve CO and VOC/HAP control efficiencies of 93%. Williams has listed the NOx, CO, and VOC/1-IAP emission factors and annual emission • Mr. Ram Seciharam CDPHE April 30, 2004 Page 3 limits at 1.5 gfbhp-hr NO,,, 0.12 gfbhp-hr CO and 0.1 g/bhp-hr VOC based on manufacturer's emission factors and to reflect the 93% control efficiency of the SCO control system. Williams also has similarly listed the individual and aggregate HAP emissions for these engines to reflect the 93% SCO control efficiency. Emergency Generators In addition to re -designating the two existing electrical generator engines to exempt emergency generator status, Williams will install four additional internal combustion engine -driven emergency electrical generators (Source ID: GEN -03, GEN -04, GEN -05, and GEN -06). These generators will be used to keep the plant operational during emergency periods when power from the electrical grid is not available. Each generator will be driven with a 1,145 Hp Caterpillar 3516 TALE -130 4 -cycle lean bum internal combustion engine. The six generators will operate a total maximum of 600 hours per year, and as such, they will meet the requirement to operate less than 100 hours/engine/year and they are exempt from permitting and APEN reporting under Colorado Regulation Number 3, IID 1.ttt.(iii). Heaters Here will be a total of two natural gas-fired process heaters at the plant. M.MBtu/hr Hot Oil Heater (Source ID: HTR -1) will remain unchanged. Williams will install a 54.0 M1VIBtufhr Hot Oil Heater (Source ID: HTR -2) that will be associated with the New Skid expansion project. Criteria and Non -Criteria Reportable pollutant emissions from both heaters are based on AP -42 emission factors. Amine Sweetening Units There will be a total of two amine sweetening units at the plant. Each will remove carbon dioxide from the plant inlet gas streams. The e.xisting.55 MMset/day amine unit (Source ID: AMINE -1) will remain unchanged, with the amine flash tank overhead vapor stream routed to the existing Process and Emergency Flare (Source ID: FLARE -1) and the arsine still rent overhead stream routed to atmosphere with an annual VOC emission limit of 13.1 tpy VOC. Emissions are based on the GRI AMINECalc computer model. Williams will install a new 125 MMscf/day amine unit associated with the New Skid expansion project (Source ID: AMINE -2). The flash tank overhead vapor stream from this unit will be routed to a new Process and Emergency Flare (Source ID: FLARE -2) associated with the New Skid Expansion, and the amine still vent overhead vapor stream will be routed to atmosphere with. an annual VOC emission limit of 14.7 tpy VOC. Emissions are based on the GRI AMINECaIc computer model. Dehydration Units There will be a total of two ethylene glycol (EG) dehydration units at the plant. Each will remove moisture from a ,commingled stream of plant inlet gas and sweetened gas from the two amine units. The;„eting 125 MMscflday amine unit (Source ID: DEHY-1), will remain unchanged, receiving 45% plant inlet gas and 55% sweet gas from tlic existing amine unit, with the flash tank overhead vapor stream routed to the existing Process and Emergency Flare (Source ID: FLARE - 1), and the regenerator still vent overhead stream routed to a 96% control dedicated flare Mr. Ram Seethararn CDPHE April 30, 2004 Pale 4 (Emission Point: DEHY-I ). This unit is designed in compliance with the requirements of the 40 CFR Part 60 Subpart 1-1I-1 ONG MACT standard. Emissions are based on the GRI GLYCaIc computer model. Williams will install a new 200 MMscflday dehydration unit associated with the New Skid expansion project (Source ID: DEHY-2). It will receive a commingled stream comprised of 37.5% plant inlet gas and 62.5% sweet gas from the new amine unit, with the flash tank overhead vapor stream from this unit routed to a new Process and Emergency Flare (Source ID: FLARE -2) associated with the New Skid Expansion, and the regenerator still vent overhead vapor stream routed to a 96% control dedicated flare (Emission Point: DEHY-2). This unit is designed in compliance with the requirements of the 40 CFR Part 60 Subpart HH ONG MACT standard. Emissions are based on the GRI GLYCaIc computer model. Process and Emergency Flares There will be a total of two process and emergency flares at the plant and two dedicated flares that are discussed under the Dehydration Unit part of this letter. The existing process and emergency flare (Source ID: FLARE -1) will remain unchanged, receiving pilot and purge gas, flash gas from the existing amine and dehydration units, and plant gas during emergency shutdown of the existing gas processing skid. It is designed to meet the requirements of 40 CFR Part 60.18 for smokeless operation of flares used as control devices. Williams will install a new process and emergency flare (Source ID: FLARE -2) associated with the New Skid expansion project. It will be of similar configuration to the existing FLARE -1 unit. It will receive pilot and purge gas, flash gas from the New Skid amine and dehydration units, and plant gas during emergency shutdown of the New Skid expansion gas processing skid. It is designed to meet the requirements of 40 CFR Part 60.18 for smokeless operation of flares used as control devices. Condensate Storage Tank Emission Sources There will be a total of two condensate tank emission sources at the plant. Each source will be comprised of two tanks that are connected via a piping manifold. All condensate tanks at the plant are designed in compliance with 40 CFR Part 60 Subpart Kb requirements. Williams is revising the annual VOC emission limit for the existing condensate tank emission source (Source ID: `IK-IITK-2) based on an assumed condensate collection rate of 3.0 bbl/day, a recent pressurized condensate sample analysis, and using the E&PTANK2.0 computer model. Williams is revising the annual VOC emission limit for this source downward from 11.8 tpy VOC to 10.2 tpy VOC. Williams will install a new condensate tank emission source (Source ID: TIC-3/TK-4) similar to the existing condensate tank emission source. The new condensate tank emission source is associated with the New Skid expansion project. Williams is listing the annual VOC emission limit for the New Skid condensate tank emission source based on an assumed condensate collection rate of 6.0 bbllday, a recent pressurized condensate sample analysis, and using the E&I'TANK2.0 computer model. Williams is listing the annual VOC emission limit for this source at 20.4 tpy VOC. Condensate and NGL Loadout Emission Sources Mr. Ram Seetharam CDPHE April 30, 2004 Page 5 There will be a total of two condensate loadout emission sources and two NGL loadout emission sources at the plant. Estimated annual VOC emissions from the existing condensate loadout emission source (Source ID: LOAD -1) and from the existing NGL loadout emission source (Source ID: LOAD -2) are each below the 2.0 tpy threshold for APEN reporting and therefore are exempt from permitting and APEN reporting. Williams will install a new condensate loadout emission source (Source ID: LOAD -3) and a new NOL loadout emission source (Source ID: LOAD -4), both associated with the New Skid expansion project. As with the existing loadout emission sources, estimated annual VOC emissions from the New Skid condensate loadout emission source and from the New Skid NGL loadout emission source are each below the 2.0 tpy threshold for APEN reporting and therefore are exempt from permitting and APEN reporting. Fugitive VOC Emissions from Leaking Equipment There will be a total of two fugitive VOC emission sources at the plant. Both sources are subject to the leak detection and repair requirements of 40 CFR Part 60 Subpart KKK. The existing fugitive emission source at the plant (Source ID: FUG -1) will remain unchanged. Estimated VOC emissions from the existing fugitive emission source were calculated based on an estimated equipment component count, a recent inlet gas analysis, using the Oil and Gas Production Operations equipment leak emission factors (from OAQPS TTN BBS, EPA -453/R-95- 017, Table 2-4), and assuming a control factor of 75%. Fugitive VOC annual emissions from this source are estimated at 3.3 tpy. An additional fugitive VOC emission source (Source ID: FUG -2) will be associated with the New Skid expansion project. Estimated VOC emissions from the New Skid fugitive emission source were calculated based on an estimated equipment component count, a recent inlet gas analysis, using the Oil and Gas Production Operations equipment leak emission factors (from OAQPS TTN BBS, EPA -453/R-95-017, Table 2-4), and assuming a control factor of 75%. Fugitive VOC annual emissions from this source are estimated at 2.9 tpy. Summary of Change in Emissions Facility -wide emissions from all permitted and exempt sources prior to and subsequent to this modification are presented below. The sources associated with the March 19 and April 29, 2004 pending permit modifications are accounted for in this emissions analysis.

Our investigation was conducted to explore subsurface conditions and provide foundation design recommendations for the proposed construction. The report includes descriptions of subsoil and groundwater conditions found in sixteen exploratory borings made during this investigation, recommended foundation systems and allowable design soil pressures and design and construction criteria for details influenced by the subsurface conditions. This report was prepared in general conformance with our Proposal No. 04-101, dated • June 4, 2004. The report was prepared from data developed during field exploration, laboratory testing, engineering analysis and experience with similar conditions. A brief summary of our conclusions and recommendations follows. Detailed criteria are presented within the report. Williams Production RMT Company Facility Addition GEG Job No. 1,691 SUMMARY OF CONCLUSIONS Subsoils found in the exploratory borings included up to 1 foot of existing fill and up to 110 feet of sandy clay underlain by variable siltstone / sandstone to the maximum depth explored. Practical drill rig refusal was encountered at 89 feet in exploratory boring TH-10 and at 113 feet in exploratory boring TH-14 in the underlying siitstone / sandstone. Groundwater was not encountered the day of drilling. We were not able to locate groundwater monitoring piezometers due to recent site grading. Variable, medium stiff to very stiff. sandy clay soils were identifiedf foundation levels. We recommend driven piles bedded in a underlying competent strata to mitigate potential settlement of structures. A competent stratum was identified at depths of 89 to 113 feet. Shallow foundations supported by well compacted structural fill is also presented for structures where more risk of potential movement is acceptable. A discussion of alternatives, including detailed design and construction criteria are included in the text of the report. We believe slab -on -grade construction supported by the soil encountered will involve low potential for movement. We recommend structurally supported floors in all finished areas. Detailed design and construction criteria area presented in the text of this report. 4. Surface drainage should be designed for rapid runoff of surface water away from the proposed structures. SITE CONDITIONS The subject site was located approximately 4 miles northwest of Parachute, Colorado on County Road 215. Fig. 1. The subject site was located in a northwest and southeast oriented valley bottom. Steeper slopes were noted along the sides Williams Production RMT Company Facility Addition GEG Job No. 1,691 2 )4 • • • of the valley. The subject site was located north and east of an existing gas production facility on vacant. undeveloped land. The ground surface was partially cleared of vegetation. Low, indigenous vegetation was noted across the remainder of the site. The subject site sloped down toward the southeast and southwest 5 to 9 percent (measured with handheld rangefinder and hand level). Scattered cobbles were noted at the surface across the site. Ar irrigation type pipe (dry at the time of our visit) was located along the southwest portion of the site. A gas production facility was southwest of the site. Parachute Creek, undeveloped land and steeper upslopes of the valley sidewalls were beyond. An asphalt paved access road was northwest with undeveloped land further upvalley. County Road 215 was north and east of the site with steeper valley sidewalls beyond to the northeast. Undeveloped land was downvaIley toward the southeast. The vicinity sloped down toward the valley bottom; the valley bottom sloped down toward the southeast at less than 1 percent (USGS Parachute, Colorado Quadrangle, 1962). PROPOSED CONSTRUCTION We understand proposed construction will consist of a gas facility addition. There will be various related structures. There will be no below grade construction. We understand the "T-501IT-502" structures, residue compressor", "refrigeration Williams Production RMT Company Facility Addition GEG Job No. 1,691 • compressor" and electric generator will have a relatively low tolerance for movement (on the order of// inch). We understand deep foundations are desired for support of these structures. The tolerance for differential movement of the remaining structures will be 2 -inches. We understand there be a tank storage area where mat foundations are desired. Shallow spread footing foundations are desired for the remainder of proposed construction. We anticipate foundation loads of 1.000 to 2.000 pounds per lineal foot of perimeter foundation wall for each structure. There may be up to 15 to 20 feet of site grading cut and fill across the site. There will be no below grade construction. If proposed construction changes or is different from what is stated. we should be contacted to review actual construction and our recommendations. SUBSURFACE CONDITIONS Subsurface conditions at the site were investigated by drilling and sampling sixteen exploratory borings. Locations of the exploratory borings are shown on Fig. 2. Graphic logs of the soils found in the borings and field penetration resistance tests are presented on Figs. 3 through 7. Subsurface conditions encountered included up to 1 foot of existing fill and at least 20 to 110 feet of sandy clay underlain by variable siltstone / sandstone to the maximum depth explored of 20 to 113 feet below the ground surface. Practical drill rig Williams Production RMT Company Facility Addition 4 GEG Job No, 1,691 • refusal was encountered at 89 feet in exploratory boring TH-10 and at 113 feet in exploratory boring TH-14 in the underlying siltstone / sandstone. The existing fill consisted of gravel, sand and clay was dry to moist and brown. The sandy clay had sandy, clayey gravel and clayey sand lenses was medium stiff to very stiff, dry to very moist, brown and had an appearance of ancient landslide / sheet flow type deposition. The siltstone / sandstone exhibited substantial drill rig resistance to practical drill rig refusal. Clay samples tested had moisture contents ranging from 5.7 to 16.9 percent and dry densities from 109 to 123 pcf. Eight clay samples were tested 411 for Atterberg limits. These samples exhibited liquid limits from 26 to 34, plasticity indices from 12 to 20 and 51 to 87 percent silt and clay sized particles (passing the No. 200 sieve). Two other clay samples had 41 and 51 percent passing the No. 200 sieve (silt and clay sized particles). Fifteen clay samples were tested for swell consolidation characteristics using a one dimensional cedometer apparatus. These samples ranged from no movement swell of 3.2 percent when wetted under a confining pressure of 500 psf or 1,000 psf. We do not believe the sample that swelled 3.2 percent is representative of soil encountered on site. Two sand samples were tested. These samples had moisture contents of 9.6 percent to 13.5 percent and dry densities of 113 and 109 pcf, respectively. One sand sample exhibited a liquid limit of 27, plasticity index of 13 and 40 percent • Williams Production RMT Company Facility Addition GEG Job No. 1,£91 • • • passing the No. 200 sieve. Another sand sample had 30 percent passing the No. 200 sieve. Two gravel samples were tested. These samples had moisture contents of 7.1 and 7.4 percent, 35 and 39 percent retained on the No. 4 sieve (gravel sized particles) and 41 and 25 percent passing the No. 200 sieve. Groundwater was not encountered the day of drilling. Piezomenters were not located during subsequent visits due to recent site grading. Results of laboratory testing are presented on Figs. 8 through 20 and summarized on Table l.. SITE DEVELOPMENT Site grading plans were not available at the time of this investigation. We understand up to 15 to 20 feet of cut and fila are proposed across the site. Prior to fill placerrent, the surface of native soils below fill should be stripped and ail organic and deleterious materials completely removed. The surface should be scarified to a depth of 10 inches, moisture conditioned to within 2 percent of optimum moisture content and compacted to at least 95 percent of standard Proctor (ASTM D 698) maximum dry density. On-site soils free of deleterious materials, organics and particles over 6 -inches diameter can be reused in non structural areas during grading. Fill in structural areas may include special. requirements as shown later under the "'FOUNDATIONS" section of this report. Additional fill placement should be moisture conditioned to within 2 percent of Wllhams Production RMT Company Facility Addition B GEG Job No. 1,691 optimum moisture content and compacted to at least 95 percent of standard Proctor (ASTM L 698) maximum dry density in 10 -inch maximum thickness loose lifts. Subgrade soils and fill greater than 15 foot in depth should be moisture conditioned to within 2 percent of maximum dry density and compacted to at least 100 percent maximum dry density standard Proctor (ASTM 0698). Subgrade preparation, and placement and compaction of grading fill should be observed and tested by a representative of our firm during construction. Sample site grading specifications are included in Appendix A. Review of Grading Fill We reviewed site grading fill records performed by our representative between June 28 and July 18, 2004. Nuclear compaction tests show recommended minimum density has been achieved on site. We did identify several tests where the recommended moisture requirement was not met. We are concerned teat some settlement potential may exist in the fill soils where the moisture content is low. We are aware the existing gas plant was compacted in a similar manner as the existing site and we are also aware there are no compaction records for the existing site. The current owners are satisfied with the performance of the existing plant and may not be concerned with the moistures. Williams Production !UV Company Facility Addition GEG Job No. 1,691 • • FOUNDATIONS This investigation indicates a variable, medium stiff to very stiff, sandy clay soils exist at foundation levels. Laboratory test results indicate the sandy day has relatively low bearing capacity and consolidation potential. We believe a foundation system that is anchored in an underlying competent strata would offer lower movement potential than shallow foundations at the subject site. Driven piling or drilled pier foundations are examples of deep foundations. Drilled pier installation would likely require casing / special installation techniques and be more expensive, We understand the "T-501 / T-502' structures, "residue compressor", "refrigeration compressor" and electric generator will have a relatively low tolerance for movement (on the order of 12 inch). We recommend driven pile foundations, embedded in a competent bearing stratum for structures where less potential movement is desired. Depth to competent bearing stratum were variable. We identified a competent stratum at approximately 89 feet in exploratory boring TH-10 and did not identify a stratum to a depth of 100 feet in exploratory boring TH-5. A competent bearing stratum was identified at 113 feet in exploratory boring TH-15. We believe it would be a prudent measure to locate each structure that requires less movement on the same foundation to further mitigate differential movement. For structures where more risk of potential for movement is acceptable an alternative of shallow foundations (spread footing and mat) bearing on well compacted structural fill is also presented. Williams Production RMT Company Facility Addition B GEG Job No. 1,691 The recommended design and construction criteria for driven piles and shallow foundations (spread footing and mat) are presented below in order of decreasing attractiveness. These criteria were developed from analysis of field and laboratory data and our experience. The owner should also consider additional +;if any) requirements established by the structural engineer. Driven Piles Pile material should be steel H sections (HP 10x42 or larger) or concrete filled, closed end, steel pipes (10 -314 -inch Q.D.. 0.25 -inch thick walled or heavier). Pipe piles are typically used in this area. Tip reinforcement should be provided to reduce pile damage during hard driving. A maximum allowable service stress of 12,000 psi should not be exceeded. Based on our experience, capacities of 50 tons to 75 tons can be developed during driving. The capacity of piles iri compression driven as described above will be the structural strength of the piles. 2. We identified a competent bearing strata at a depth of 89 to 113 feet below existing ground surface. We anticipate deeper depths to competent stratum across the site. 3. Groups of piles placed closer than three diameters, center to center, should be evaluated to determine their reduced capacity. 4. The pile driving hammer should be operated at the manufacturer's recommended stroke and speed when the "set" is measured, 5. The contractor should select a driving hammer and cushion combination which is capable of installing selected piles without overstressing the pile. The contractor should submit the pile driving plan and the pile hammer cushion combination to the structural engineer for evaluation of the driving stress in advance of the pile installation. Williams Production RMT Company Facility Addition 9 GEG Job No. 1.691 • • • 6. We believe a modulus of subgrade reaction of 50 to 150 psi/in can be used for lateral resistance of pile caps. A plate load test can be performed to provide a more direct correlation between site soils and modulus of subgrade reaction. 7. A representative of our office should observe and keep records of penetration resistance, pile lengths and other factors that could affect the performance of the foundation, during driving. Spread Footings- Structures where more potential risk of movement is acceptable 1 Existing soils should be removed to at least a depth of 2 feet below and 2 feet horizontally beyond footings in each direction and replaced with a well compacted structural fill. The resulting subgrade should be prepared by scarifying 10 -inches, moisture conditioning to with 2 percent of optimum moisture and compacting to at least 95 percent of standard Proctor (ASTM D698) maximum dry density. Structural fill soils should consist of well graded sands and gravels with a maximum particle size of 3 -inches, maximum 30 percent passing the No. 200 sieve and maximum liquid limit of 30 percent. A COOT type Class 5 aggregate base course would meet this criteria and is recommended. A sample of the proposed fill soils should be supplied to our office for acceptance testing, prior to use or import. Additional fill should be moisture conditioned to within 2 percent of optimum moisture content and compacted to at least 95 percent of standard Proctor (ASTM D698) maximum dry density in 10 -inch maximum loose lifts. 2. Footings bearing on well compacted structural fill placed as stated above should be designed for a maximum soils bearing pressure of 1,000 psf. Loose soils should be completely removed from foundation bearing areas, prior to placing concrete. 3. We recommend a minimum width of at least 18 -inches for Williams Producton RMT Company Facility Addition 16 GEG Job No. 1,691 • • continuous footings. Isolated pads should be at feast 36 inches by 36 inches. Foundation walls should be well reinforced top and bottom. We recommend reinforcement sufficient to span an unsupported distance of at least 15 feet. Reinforcement should be designed by the structural engineer. Exterior walls should be protected from freezing. We understand the normal depth assumed for frost protection in the Garfield County area is 3 feet. 5. The completed foundation excavation should be inspected by our representative for proof roll and to verify the subsurface foundation conditions are as anticipated from our boriiings. Geotechnical Engineering Group should also be called to test compaction of subgrade and fill during placement. Mat Foundations — (tank storage areas) 1 Mat foundations can be designed for a maximum soils bearing pressure of 500 psf. Loose soils should be completely removed from foundation bearing areas. prior to placing concrete.. 2. Existing soils should be removed to at least a depth of 2 feet below and 2 feet horizontally beyond mat in each direction and replaced with a well compacted structural fill. The resulting subgrade should be prepared by scarifying 10 -inches, moisture conditioning to with 2 percent of optimum moisture and compacting to at least 95 percent of standard Proctor (ASTM D698) maximum dry density. Structural fill soils should consist of well graded sands and gravels with a maximum particle size of 3 -inches, maximum 30 percent passing the No. 200 sieve and maximum liquid limit of 30 percent. A CDOT type Class 5 aggregate base course would meet this criteria and is recommended for structures where minimizing potential movement is a concern. A sample of the proposed fill soils should be supplied to our office for acceptance testing, prior to use or import. Additional fill should be moisture conditioned to within 2 percent of optimum moisture content and compacted to at least 95 percent of standard Proctor (ASTM D698) maximum dry density in 10 -inch maximum loose lifts. Wlil ar is Production RMT Company Facility Addition 11 GEG Job No. 1,691 • • Mat foundations should be well reinforced, bath top and bottom. We recommend reinforcement sufficient to span an unsupported distance of at least 12 feet. Reinforcement should be designed by the structural engineer. Foundations should be protected from freezing. The normal depth assumed for frost protection in the Garfield County area is 3 feet. The completed foundation excavation should be observed by our representative to verify subsurface foundation conditions are as anticipated from our borings and to test compaction. FLOOR SYSTEMS The near -surface soils which will support slab -on -grade floors exhibited low movement potential. Some movement must be assumed_ To our knowledge, the only reliable solution to control floor movement is the construction of a structurally supported floor with at least a 12 -inch air space between the floor and subgrade. In our opin on, structural floors should be used in all finished areas. We recommend the following precautions for construction of slabs -on -grade at this site, These precautions will not prevent movement in the event the underlying conditions become wetted; they tend to reduce damage if movement occurs, Slabs should be supported by at least a 1 foot depth of well Williams Production RMT Company Facility Addition 12 GEG Jots No. 1,691 compacted. structural fill as stated above under the "FOUNDATIONS, Spread Footings" section of this report. The completed subgrade should be scarified 10 -inches depth, moisture conditioned to within 2 percent of optimum moisture content and compacted to at least 95 percent of maximum standard Proctor (ASTM D698) dry density. prior to structural fill placement. A Geotechnical Engineering Group, Inc. representative should be called to visit the site to test compaction and observe soils in the excavation bottom and structural fill. 2. Slab -on -grade construction should be limited to unfinished areas and exterior flatwork where practical. Slabs should be separated from exterior walls and interior bearing members with a slip joint which allows for free vertical movement of slabs. The use of slab -bearing partitions should be minimized. Where such partitions are necessary. a slip joint allowing at least 2 inches of free vertical slab movement should be used. Doorways and stairwells should also be designed for this movement. Underslab plumbing should be eliminated where feasible. Where such plumbing is unavoidable, it should be thoroughly pressure tested during construction for leaks and should be provided with flexible couplings. 6. Frequent control joints should be provided to reduce problems associated with shrinkage and curling. The American Concrete Institute (ACI) and Portland Cement Association (PCA) recommend a maximum panel size of 8 to 15 feet depending upon concrete thickness and slump, and the maximum aggregate size. We advocate additional control joints 3 feet off and parallel to grade beams and foundation walls. Williams Production RMT Company Facility Addition 13 GEG Job No. 1,691 • • • BELOW -GRADE CONSTRUCTION No below -grade construction is anticipated at this site. Typically. foundation drains are not required for construction of this type. Crawl space areas should be sloped so that potential moisture will not collect in these areas. but flow out of the crawl space. Crawl space areas should also be well ventilated to mitigate potential musty odors. CONCRETE Twc sods samples (TH-3 and TH-12 at 4 foot depth) tested had a water- soluble sulfate concentrations of 65 and 280 ppm. Sulfate concentrations in this area are considered to have a negligible to moderate effect on concrete that comes into contact with the soils. We recommend a Type II (sulfate resistant) cement be used for concrete that comes into contact with the subsoils. In addition, concrete should have a maximum water -cement ratio of 0.5. SURFACE DRAINAGE Performance of foundations and concrete flatwork is influenced by surface moisture conditions. Risk of wetting foundation soils can be reduced by carefully Williams Production RMT Company Facility Addition 14 GEG Joh No, 1,691 • planned and maintained surface drainage. Surface drainage should be designed to provide rapid runoff of surface water away from the proposed structures. We recommend the following precautions be observed during construction and maintained at all time after the construction is completed. The ground surface surrounding the exterior of the structures should be sloped to drain away from the additions in all directions. We recommend a slope of at least 12 inches in the first 10 feet around the additions. where possible. In no case should the slope be less than 6 inches in the first 5 feet. The ground surface should be sloped so that water will not pond adjacent to the additions. 2. Backfill around foundation walls should be moistened and compacted. 3. Roof downspouts and drains should discharge well beyond the limits of all backfill. Splash blocks and downspout extenders should be provided at all discharge points. Landscaping should be carefully designed to minimize irrigation. Plants used close to foundations should be limited to those with low moisture requirements; irrigated grass should not be located within 5 feet of the foundation. Sprinklers should not discharge within 5 feet of foundations. irrigation should be limited to the minimum amount sufficient to maintain vegetation; application of more water will increase likelihood of slab and foundation movements. 5. Impervious plastic membranes should not be used to cover the ground surface immediately surrounding the structures. These membranes tend to trap moisture and prevent normal evaporation from occurring. Geotextile fabrics can be used to limit the weed growth and allow for evaporation.

DESCRIPTION This item shall consist of the excavation, transportation, placement and compaction of materials from locations indicated on the plans, or staked by the Engineer, as necessary to achieve preliminary street and overlot elevations. These specifications shall also apply to compaction of excess cut materials that may be placed outside of the subdivision and/or filing boundaries. 2. GENERAL The Soils Engineer shall be the Owner's representative. The Soils Engineer shall approve fill materials, method of placement, moisture contents and percent compaction, and shall give written approval of the completed fill.. 3. CLEARING JOB SITE The Contractor shall remove all trees, brush, and rubbish before excavation or fill placement is begun. The Contractor shall dispose of the cleared material to provide the Owner with a clean, neat appearing job site. Cleared material shall not be placed in areas to receive fill or where the material will support structures of any kind. 4. SCARIFYING AREA TO BE FILLED All topsoil and vegetable matter shall be removed from the ground surface upon which fill is to be placed. The surface shall then be plowed or scarified until the surface is free from ruts, hummocks or other uneven features, which would prevent uniform compaction by the equipment to be used. 5. COMPACTING AREA TO BE FILLED After the foundation for the fill has been cleared and scarified. it shall be disked or bladed until it is free from large clods, brought to the proper moisture Job No. 1,691 Fig. A-1 content (within 2 percent above or below optimum) and compacted to not less than 95 percent of maximum density as determined in accordance with ASTM D 698. If soft) yielding subgrade conditions are encountered, stabilization may be required. 6. FILL MATERIALS Fill soils shall be free from vegetable matter or other deleterious substances, and shall not contain rocks or lumps having a diameter greater than six (6) inches. Fill materials shall be obtained from cut areas shown on the plans or staked in the field by the Engineer, On-site materials classifying as CL, SC, SM, SW, SP, GP, GC and GM are acceptable. Concrete, asphalt, organic matter and other deleterious materials or debris shall not be used as fill. 7. MOISTURE CONTENT Fill materials shall be moisture treated to within 2 ± percent of optimum moisture content as determined from Proctor compaction tests. Sufficient laboratory compaction tests shall be made to determine the optimum moisture content for thee various soils encountered in borrow areas. The Contractor may be required to add moisture to the excavation materials in the borrow area if, in the opinion of the Soils Engineer. it is not possible to obtain uniform moisture content by adding water on the fill surface, The Contractor may be required to rake or disk the fill soils to provide uniform moisture content through the soils. The application of water to embankment materials shall be made with any type of watering equipment approved by the Soils Engineer, which will give the desired results. Water jets from the spreader shall not be directed at the embankment with such force that fill materials are washed out. Should too much water be added to any part of the fill, such that the material is too wet to permit the desired compaction from being obtained, rolling and all work on that section of the fill shall be delayed until the material has beer allowed to dry to the required moisture content. The Contractor will be permitted to rework wet material in an approved manner to hasten its drying. 8. COMPACTION OF FILL AREAS Selected fill material shall be placed and mixed in evenly spread layers. After each fill layer has been placed, it shall be uniformly compacted to not less than the specified percentage of maximum density. Expansive soils classifying as Job No. 1,691 Fig. A-2 • CL or SC shall be compacted to at least 95 percent of the maximum dry density as determined in accordance with ASTM D 698 (100 percent for fill deeper than 15 feet below final grade). At the option of the Soils Engineer, soils classifying as SW, SP, GP. GC or GM may be compacted to 90 percent of the maximum density as determined in accordance with ASTM D 1557 (95 percent for fill deeper than 15 feet below final grade). Fill materials shall be placed such that the thickness of loose material does not exceed 10 inches and the compacted lift thickness does not exceed 6 inches. Compaction, as specified above, shall be obtained by the use of sheepsfoot rollers, multiple -wheel pneumatic -tired rollers, or other equipment approved by the Engineer for soils classifying as CL or SC. Granular fill shall be compacted using vibratory equipment or other equipment approved by the Soils Engineer. Compaction shall be accomplished while the fill material is at the specified moisture content. Compaction of each layer shall be continuous over the entire area. Compaction equipment shall make sufficient trips to insure that the required density is obtained. 9. COMPACTION OF SLOPES Fill slopes shall be compacted by means of sheepsfoot rollers or other suitable equipment. Compaction operations shall be continued until slopes are stable, but not too dense for planting, and there is no appreciable amount of loose soil on the slopes. Compaction of slopes may be done progressively in increments of three to five feet (3' to 5') in height or after the fill is brought to its total height. Permanent fill slopes shall not exceed 3:1 (horizontal to vertical). 10. DENSITY TESTS Field density tests shall be made by the Soils Engineer at locations and depths of his choosing. Where sheepsfoot rollers are used, the soil may be disturbed to a depth of several inches. Density tests shall be taken in compacted material below the disturbed surface. When density tests indicate that the density or moisture content of any layer of fill or portion thereof is below that required, the particular layer or portion shall be reworked until the required density or moisture content has been achieved. 11. COMPLETED PRELIMINARY GRADES All areas, both cut and fill, shall be finished to a level surface and shall meet the following limits of construction: A. Overlot cut or fill areas shall be within plus or minus 2/10 of one foot. Job No. 1,591 Fig, A-3 • 6. Street grading shall be within plus or minus 1110 of one foot. The civil engineer, or duly authorized representative, shall check all cut and fill areas to observe that the work is in accordance with the above limits. 12. SUPERVISION AND CONSTRUCTION STAKING Observation by the Soils Engineer shall be continuous during the placement of fill and compaction operations so that he can declare that the fill was placed in general conformance with specifications. All inspections necessary to test the placement of fill and observe compaction operations will be at the expense of the Owner. All construction staking will be provided by the Civil Engineer or his duly authorized representative. Initial and final grading staking shall be at the expense of the owner. The replacement of grade stakes through construction shall be at the expense of the contractor. 13. SEASONAL LIMITS No fill material shall be placed, spread or rolled while it is frozen, thawing, or during unfavorable weather conditions. When work is interrupted by heavy precipitation, fill operations shall not be resumed until the Soils Engineer indicates that the moisture content and density of previously placed materials are as specified. 14. NOTICE REGARDING START OF GRADING The contractor shall submit notification to the Soils Engineer and Owner advising them of the start of grading operations at least three (3) days in advance of the starting date. Notification shall also be submitted at least 3 days in advance of any resumption dates when grading operations have been stopped for any reason other than adverse weather conditions. 15. REPORTING OF FIELD DENSITY TESTS Density tests made by the Soils Engineer. as specified under Density Tests" above, shall be submitted progressively to the Owner. Dry density, moisture content, of each test taken and percentage compaction shall be reported for each test taken. Job No. 1,691 Fig. A-4 • 16. DECLARATION REGARDING COMPLETED FILL • • The Soils Engineer shall provide a written declaration stating that the site was filled with acceptable materials, or was placed in general accordance with the specifications. 17. DECLARATION REGARDING COMPLETED GRADE ELEVATIONS A registered Civil Engineer or licensed Land Surveyor shall provide a declaration stating that the site grading has been completed and resulting elevations are in general conformance with the accepted detailed development plan.

Romatzke with the CDOW regarding the project. In general, Mr. Romatzke agreed wih the 8' tall chainlink fence installation at the perimeter of the plant site. We will be meeting with Mr. Romatzke regarding other wildlife issues on the remainder of the 1,333 acre parcel. We have included a letter from 2002 from Perry Will with the Colorado Division of Wildlife. Item #4 in the letter deals specifically with the Parachute Creek Gas Plant 2002 Special Use Permit Application and notes "The biggest wildlife impact is the loss of the acreage at the plant site (10ac). The area was an alfalfa field and heavily utilized by deer for transition and winter forage. The Division of Wildlife supports fencing the entire site for protection of the site and to keep wildlife from entering." Williams Production RMT Co. agrees to install a new 8' tall chainlink fence to surround the plant expansion as shown on the Site Plan_ The new chainlink will tie directly into the existing chainlink fence that surrounds the existing plant. Please also find attached an article regarding Williams Production RMT Co., Principal Environinental Specialist, Dave Cesark's efforts in cooperation with the Colorado Division of Wildlife. Dave Cesark and CDOW have worked together to produce a Wildlife Enhancement Plan on neighboring Williams Production RMT Co. property that will aid in protection of riparian areas, reduce overgrazing, removing noxious weeds and will improve habitat for mule deer, native wild turkey and rainbow and brown trout.

We have the following comments: 1. Cumulative Impacts: The Environmental Assessment prepared by the BLM refers to cumulative impacts studied and says that there are no significant cumulative impacts. The Division of Wildlife does not believe that cumulative impacts of the projects have been fully considered or disclosed. The EA document does not elaborate on cumulative concerns, such as the impacts from future well development that will supply gas to this pipeline. The EA purpose and need states that this pipeline is needed to service existing gas wells as well as future wells and increased natural gas demands. Although this pipeline will have little direct impact on wildlife, the cumulative impacts of existing and future wells remains to be seen or analyzed. More gas wells will obviously be drilled in Garfield County and it is not known how many gas wells in Mesa County would be put in place and connected to this pipeline. Fragmentation and degradation of wildlife habitats is likely to occur with increased gas field developments resulting from this pipeline installation. Furthermore, if any portion of the increased need is planned to come from future itJrQ leases on the Naval Oil Shale Reserve or increased production of existing NOSR leases, then it should be disclosed and possibly be a pipeline over which FERC should have some regulatory authority. 2. Reclamation Plan: The Mesa County CUP plan states that excessive rock supplies will be distributed over the pipeline right-of-way in piles or rows. We encourage replacement of rocks, in DEPARTMENT OF NATURAL RESOURCES, Greg E. Walcher, Executive Diredar WILDLIFE COMMISSION, Rick Enstrom, Chair • Robert Shoemaker, Vice -Chair • Marianna Raftopouros, Secretary ■,e,.....s.....-, .........-1 aI...,.. _ o"..a.. _ 011...r... — comparable natural densities, wherever rock outcroppings are disturbed. This helps mitigate impacts to reptiles, small mammals and some bird species. The Division of Wildlife supports boring beneath some of the rock outcroppings, which, will preserve habitat for the above species types. In general, both plans should place more emphasis on invasive weed monitoring and control, throughout the lives of the pipeline and plant facility. We encourage the requirement to inspect and clean equipment for weeds before the equipment enters construction sites. Revegetation success should not just be based on the density of preferred plant species; it should also be based on the absence of invasive and noxious weeds. The Garfield County SUP plan assumes access to irrigation water for reclamationlrevegetation purposes. However, it states in Exhibit A, page A-2, that the water rights in the irrigation ditches have been previously sold. The availability of this water plays a significant role in the vegetative status of the historic agricultural lands in the permit area. It may also significantly affect reclamation success and the ability to prevent noxious weed invasion. 3. Pipeline Routing: Riparian areas should be avoided. Though the Colorado River floodplain and riparian community are avoided, we are concerned about the riparian area along Parachute Creek in Garfield County. There are Cooper's Hawk and Northern Harrier nests along Parachute Creek in the vicinity of the proposed route. The route should be surveyed for active nests, and the timing of construction activities adjusted accordingly. 4. Gas Plant (Garfield County): The biggest wildlife impact is the loss of the acreage at the plant site (10ac.). The area was an alfalfa field and heavily utilized by deer for transition and winter forage. The Division of Wildlife supports fencing the entire site for protection of the site and to keep wildlife from entering. We appreciate the opportunity to comment on this project. If you have any questions, please call me at 255-6100. Sincerely, Perry Will Area Wildlife Manager (Acting) xc: Catherine Robertson, BLM — Grand Junction Ann Heubner, BLM-Glenwood Springs Steve Yamashita Joe Gumber John Broderick John Toolen Williams works to turn producing property into productive wildlife habitat When Dave Cesark envisions the 1,404 acres of land Williams owns and develops for natural gas in the Parachute Creek Valley of western Colorado, he sees hundreds of mule deer, thriving alfalfa fields and pristine creeks. The principal environmental spe- cialist for Exploration & Production's office in Parachute is leading a proj- ect not just to protect the lands where we operate some 20 natural gas wells. but to enhance the prop- erty for wildlife's sake. "We want to turn this place into a mecca for wildlife," Dave says of the Williams -owned acreage. "It will be rewarding down the road to see how it develops and improves over the years and how the wildlife pop- ulation continues to grow and thrive on the property. That's when we'll be able to look back and feel like we've accomplished something," Working closely with Colorado's Division of Wildlife, Williams start- ed what Dave calls the Wildlife Habitat Enhancement Plan for the property about a year ago. When Williams acquired the land in 2001, it had been overgrazed by cattle and was in need of work to get it in shape to support a mix of wildlife ranging from native wild turkey and mule deer to rainbow and brown trout. With the help of a property manag- er possessing expertise in wildlife biology and range management, the project began with a year's worth of work that included taking wildlife inventories, producing accu- rate maps of the area, recording wildlife observations and consider- ing potential management options. What lies ahead is a list of priori- ties to improve the land over the next five years. Plans include implementing a livestock grazing management program, installing fencing to protect the riparian area, removing noxious weeds, seeding to improve alfalfa growth, planting an acre's worth of cotton- wood trees and equipping existing Mule deer congregate on Williams -owned land in the Parachute Creek Valley of western Colorado. Working closely with Colorado's Division of Wildlife. Williams began a Wildlife Habitat Enhancement Plan for the property about a year ago to improve the mule deer population. Dave Cesark stands in front of a beaver pond on Williams -owned property in Parachute Creek Valley where he's leading a Wildlife Habitat Enhancement Plan. trees with wire wrappings to pro- tect them from beaver damage. As an added benefit, the Division of Wildlife plans to use the land as a training ground for its youth hunting program beginning this spring. The division also is in the process of forming a formal part- nership with Williams to provide oversight on the project. As a community leader, Dave says the company recognizes the importance of going above and beyond the regulatory require- ments to be good environmental stewards of the land. Not only is Williams the largest taxpayer and employer in Garfield County, but it also is committed to raising the bar for protecting our lands for generations to come. "It's important not only to reclaim the lands we use, but to make them better than they were before;" Dave says. "This project is a perfect example of us trying to do just that."

Williams Production RMT Company is proposing to increase the full time employment at the facility by five FTEs, from the current 15 to 20 in the future. The number of trucks that load at the plant will increase by 12, from the current six to a total of 18 in the future. Our study is based on the traffic count data that was compiled by Sopris Engineering, LLC. The following is our analysis of potential traffic impacts that might result from this proposed expansion. EXISTING TRAFFIC Turning movement volumes were manually counted for a total of two days and were summarized in 15 minute periods. These counts were taken at five intersections/driveways in the vicinity of the existing gas plant. The count program included the intersection of CR 215 and Mancamp Road as well as four intersections on Mancamp Road (three serve the gas plant and the other is the Well Access Road). Counts were taken from 7:30 am on August 12, 2004 to 8:00 am on August 13, 2004. Counts were also taken from 6:30 am on August 16, 2004 to 7:30 am on August 17, 2004. The resulting daily volumes for these two 24-hour counts are shown in Figure 1. These counts specifically surveyed the three access points that serve the gas plant and show that there were a total of 234 vehicles per day (vpd) on August 12-13 going into or out of the gas plant. Trucks comprised 48 of these daily vehicles (21°,6). On August 16-17, there were a total of 253 vpd with 38 vpd being trucks (15%). The 15 -minute data for both of the days were reviewed to determine the pattern of peak hours through the day. The following peak hour period were determined: • On August 12, 2004 (Thursday), the morning peak hour occurred between 7:45 am and 8:45 am while the morning peak hour on August 16, 2004 (Monday) occurred between 6:30 am and 7:30 am. The resulting morning peak hour turning movement volumes are shown in Figure 2. 6300 South Syracuse Way, Suite 600 Centennial, CO 80111 tel 303.721.1440 fax 303.721.0832 www.f-hueng.com info@fhueng.com August 27, 2004 Mr. Phil Vaughan Page 2 • A mid-day peak hour occurred on August 12th between 11:15 am and 12:15 pm, and the mid-day peak hour on August 16, 2004 occurred between 10:30 am and 11:30 am. The resulting mid-day peak hour turning movement volumes are shown in Figure 3. • On August 12, 2004, the evening peak hour occurred between 5:00 pm and 6:00 pm, and the evening peak hour on August 16, 2004 occurred between 3:00 pm and 4:00 pm. The resulting evening peak hour turning movement volumes are shown in Figure 4. Operational analyses of the five study intersections and driveways were performed according to the techniques documented in the Highway Capacity Manual 2000, by the Transportation Research Board (TRB), 2000. The result of such an analysis is a level of service (LOS) rating, which is a qualitative assessment of the traffic flow based on the average stopped delay per vehicle at a controlled intersection. Levels of service are described by a letter designation ranging from "A" to "F" with LOS A representing essentially uninterrupted flow, and LOS F representing a breakdown of traffic flow with excessive congestion and delay. The results of this analysis shows that morning, mid-day, and evening peak hour volumes at all five intersections/driveways currently operate at LOS A (see Figures 2, 3, and 4). SITE -GENERATED TRAFFIC The Parachute Creek Gas Plant is a unique land use, and the detailed traffic counts that were collected in the field provide ample information on which to base future traffic forecasts. The forecasts of future traffic (see Table 1) are based on the following methodology: • Future daily and hourly volumes are based on an average of the two count periods. • Truck traffic related to the site is assumed to increase in proportion to the forecast of future trucks serving the site. All truck volumes were multiplied by a factor of 3,0. This is the ratio between 18 trucks in the future and 6 currently. • Automobile traffic related to the site is assumed to increase in proportion to the forecast of future employees working at the site. All automobile volumes were multiplied by a factor of 1.33. This is the ratio between 20 full time employees in the future and 15 currently. Table 1. Trip Generation Analysis Total Volume (Truck Volume) Daily Morning Peak Hour I Mid -Day Peak Hour Evening Peak Hour Current 8/12 — 13/04 234 (48) 17 (4) 21 (5) 26 (3) 8/16 — 17/04 253 (38) 24 (0) 1 22 (3) 23 (3) Average 244 (43)21 (2) 22 (4) 25 (3) Future 397 (129) I 32 (7) 42 (14) 40 (10) • August 27, 2004 Mr. Phil Vaughan Page 3 The results of this analysis show that there will be approximately 400 trips per day with the proposed expansion of the gas plant with between 32 and 42 trips occurring during the morning three peak hours. Daily traffic at the plant will grow by approximately 63%. Truck traffic will represent approximately 32% of the total traffic in the future, up from 15 — 20% currently. BACKGROUND TRAFFIC GROWTH In addition to the expansion of the gas plant, it was assumed that general growth in the county will result in corresponding growth in background (unrelated to the project) traffic volumes on both CR 215 and Mancamp Road, A growth rate of 4% per year was assumed for this analysis. This is higher than the approximate 3% growth rate in population for Garfield County that is forecasted by the State of Colorado Demography Office over the next 20 years. Background traffic growth was assumed to occur at the 4% rate over the next 20 year — through 2024. TOTAL TRAFFIC AND LEVELS OF SERVICE Figures were prepared showing the total average daily and peak hour traffic volumes (site generated and background) that were forecasted for 2024. These figures are as follows: • Figure 5 — 2024 Total Daily Traffic Volumes • Figure 6 — 2024 Morning Peak Hour Traffic Volumes • Figure 7 -- 2024 Mid -Day Peak Hour Traffic Volumes • Figure 8 -- 2024 Evening Peak Hour Traffic Volumes Level of service analyses were also completed for the five project intersections/driveways for each of the three peak periods. Figures 6, 7, and 8 show that all of the intersections/driveways will continue to operate at LOS A over the next 20 years. CONCLUSION The results of the level of service analyses show that there will not be any traffic operational concerns, and all intersections and driveways will operate well (LOS A).

SUP Application and has been revised and items have been added below as per comments from Steve Anthony. An inventory of noxious weeds was completed for the riparian area consisting of approximately 100 acres within the 1,333 -acre parcel owned by Williams Production RMT Co. This was completed as part of the Parachute Creek Wildlife Enhancement Project. " 2.3 acres of tamarisk was identified and was eradicated in Spring 2004. Additionally, hounds tongue and various thistles were identified and eradicated. Steve Anthony and I discussed that a reclamation bond will be required by Garfield I County for the new and existing plant site totaling approximately 20 acres of surface disturbance. Please note that the above and attached information presented discusses a carefully implemented plan for mitigation of impacts caused by the Parachute Creek Gas Plant. The majority of these mitigation strategies are currently in-place in the existing Parachute Creek Gas Plant and will be extended to the expansion. Please contact me with any questions. Sincerely, Philip B. Vaughan President PVCMI Page 1 of 1 SITE REHABILITATION PLAN PARACHUTE CREEK GAS PLANT EXPANSION 44 he Parachute Creek Gas Plant Expansion (Plant Expansion) will be located on rangeland owned by Williams Production MT Company (Williams). The Plant Expansion area is 9.57 acres and is immediately adjacent to the existing plant. The subject site appears to lie in the Villa Grove soil series. The Villa Grove series consists of deep, well -drained soils that formed in alluvium derived from sandstone, shale, or basalt. The soil should be stripped to a depth of approximately twelve (12) inches and stockpiled at the facility margins. The maximum depth of stockpiled shall be 24" or less to preserve soil viability. Topsoil stockpiles will be seeded as described below in the section on seeding methods and times. RECLAMATION Two phases of reclamation are planned. Soil stockpiles and areas disturbed by construction that will not be utilized during Plant Expansion operation will be reclaimed immediately following Plant Expansion construction. Final reclamation will be performed within one year of Plant Expansion closure and removal. The objectives of reclamation will be as follows: • 1. Stabilization of the disturbed areas will be conducted by providing wind and water erosion control to reduce soil loss. 2. Utilize the prescribed seed mixtures and additional vegetation practices as described below to establish a self- sustaining vegetative rangeland cover for cattle pasture use. FACILITY AND STRUCTURE REMOVAL The Plant Expansion will be abandoned in accordance with Colorado Oil and Gas Conservation Commission regulations in place at the time of facility abandonment. Equipment will be removed from the site. BACKFILLING, GRADING, AND RE -CONTOURING Reclaimed areas will be sloped to 3:1 or less. • Page 1 of 3 TOPSOIL REPLACEMENT Soil salvaged during Plant Expansion construction activities will be redistributed over the soil surface after subsoil has (ken replaced and additional backfilling; grading, and re -contouring steps have been completed as described below. Soil will be replaced by using front-end loaders, trackhoes, and dozers. Soil will not be replaced when itis excessively wet and frozen so as to jeopardize soil structure. SEEDBED PREPARATION/SOIL TILLAGE Seedbed preparation and soil tillage will be completed after the application of subsoil, topsoil, and any soil amendments. Soil tillage will be to a minimum depth of 4" utilizing a disk, chisel plow, or harrow. Seedbed preparation will also include removal of coarse fragments (rock material) that exceed 35% to 40% of the soil surface as well as rocks 8" in diameter that occupy more than 10% of the soil surface. SEEDING METHODS AND TIMES Soil stockpiles and areas disturbed by construction that will not be utilized during Plant Expansion operation will be seeded. If seeding is performed in the spring, it will be accomplished by May 15; if fall seeding is performed it will be completed after August 30 and before the soil freezes, Seeding efforts will consist of drill seeding with a rangeland drill to a planting depth of ''/d" to '//" on slopes 3.1 or flatter. Broadcast seeding followed by harrowing or hand raking to lightly glover the seed with soil will be used on slopes steeper than 3:1, or on areas inaccessible for drill seeding equipment. All areas to be reclaimed will be mulched no later than 24 hours after seeding with a certified weed -free straw or grass hay material. Grass hay mulch will be applied at 1 /2 tons per acre, or straw mulch will be applied at 2 tons per acre. Mulch material will be crimped into the soil surface with a commercial mulch crimper, a straight disc, or bulldozer tracks if too steep to otherwise crimp mulch in place. SEED MIXTURES Please see Table 1 for the seed mixtures. WEED CONTROL PLAN A qualified person will inspect the Plant Expansion area and will inventory and map the proposed project area for any listed Garfield County noxious weeds. Based on this inventory and mapping, methods, materials, and timing of weed control measures will be specified. The vast majority of the Plant Expansion area will be graveled and will be devoid of vegetation. • Page 2 of 3 TABLE 1 Stockpile and Disturbed Areas Reclamation TABLE 2 Final Reclamation Seed Mixture Common Name Scientific Name Pounds Pure Live Seed (PLS) per acre AIkal Sacaton Sporobdus aims 1.0 Sideoats Grama Boute1oua curtipendula 2.0 Basin Wikirye Leymus cinereus 2.0 Westem wheatgrass Pascopyrurn sim4hW 4.0 TOTAL PLS 9.0 Page 3 of 3 Pyr -1 4T Land Planning Division 1 nn. n !-, T, } 1 -1 1 1 UJO t uulity nunu .)L.)

The items noted below were discussed during our meetings regarding fire protection issues at the Parachute Creek Gas Plant. Plant Safety Systems and Plant Design Plant spacing is designed as to minimize impact fire and aitow unobstructed access tor outside fire fighting equipment (i.e. trucks). NGItb tanks are set back from county road 215 as per 1NFPA spacing requirements. Plant st t systems include gas and tire detection, which either shuts down or isolates specific equipment and/or plant when activated.

Fire extinguishers are located throughout the plant, so plant pe stage fires. Loading Rack and Truck Drivers el can fight incipient Truck drivers are given a safety briefing i safety orientation when they arrive to haul there first load from our plant. Also, for new drivers one of our plant personnel goes to the loading rack with the driver to discuss the loading process. Page 1 of 3 • I ruck drivers must check-in at the office by signing m, at which time they are given a loading ticket. They then travel to the loading rack and hook-up. Once they have achieved a proper ground, the control room receives a signal and allows loading to begin. Safely equipment at the loading rack includes breakaway valves which shutdown the flow of liquid in the event ofa line problem. Also, an Emergency Shut Down (ESD) button is located near the rack, which shuts down the loading process in the event of an emergency when manually activated. Fire Training Fire extinguisher training is provided to Williams employees on a annual basis. Emergency Response Plan i he current emergency response pian (EKY) will be updated to include the plant expansion and will be reviewed with the GVFPD. A copy is also available via the Local Emergency Planning Committee (LEPC). Perimeter access for G V ii Pia will be provided and clearance under piperacks at certain locations for vehicle crossings will be provided.
