PSCo is aware that eight copies are required; however, at the direction of the Garfield County Building and Planning Department, one copy is submitted at this time. Subsequent copies will be provided at the direction of the planning department. In addition, for your information this is a joint project between Rocky Mountain Natural Gas Company, A subsidiary of Kinder Morgan, Inc. and Public Service Company of Colorado. As a point of clarification, the Company name may be confusing since our utility company name is "branded" as Xcel Energy (TV, news ads, bills, etc.); however, the legal owner and operator of the utility facilities in Colorado is Public Service Company of Colorado. Since Xcel Energy is only the holding company or "brand" for Public Service Company of Colorado, all utility facilities and related land rights, including fee property, easements, permits, etc., are owned by, operated by and held in the name of Public Service Company of Colorado, a Colorado Corporation. The proposed Rifle Discharge Compressor Station would reinforce the existing 12 -inch high-pressure natural gas pipeline that delivers gas between the Rifle Gas Plant and the Edwards Meter Station. This pipeline provides gas to Silt, New Castle, Glenwood Springs, Basalt, Aspen, Gypsum, Eagle, Edwards, Avon, and the Vail Valley. This reinforcement would be accomplished by raising the operating pressure of the pipeline to provide a greater throughput volume for the existing pipeline. The increase in pressure would be achieved by installing a new compressor at the outlet of the existing Rifle Gas Plant. The only pipelines required for this project would be the lead lines to connect the new compressor to the existing gas plant. . The Rifle Discharge Compressor Station will 1 reinforce the existing supply systems and allow customers located in the area to continue to receive reliable and economical natural gas service. 1 1 1 This information is submitted for review, referral, and consideration for approval by the Garfield County Board of County Commissioners and Planning Commission in accordance with C.R.S. 29-20-108.

SPECIAL USE PERMIT APPLICATION Application Requirements: These items must be submitted with the application. A complete, signed Special Use Form is submitted on the previous page. The following items, 1 through 7, address the requirements in the Special Use Permit Application. SUMMARY OF APPLICATION Public Service Company of Colorado (PSCo) proposes to construct and operate a natural gas booster compressor station at the existing Rifle Gas Plant owned and operated by PSCo and Rocky Mountain Natural Gas (RMNG) located on private property 2 miles west of Rifle. The proposed compressor station would be called the Rifle Gas Plant Discharge Compressor Station - Rifle Gas Plant, but is also referred to as the Rifle Discharge Compressor Station in this application. A Special Use Permit was approved in 1994 for the existing Rifle Gas Plant. The Rifle Discharge Compressor Station would reinforce the existing 12 -inch high-pressure gas pipeline that delivers gas between the Rifle Gas Plant and the Edwards Meter Station. This pipeline provides gas to Silt, New Castle, Glenwood Springs, Basalt, Aspen, Gypsum, Eagle, Edwards, Avon, and the Vail Valley. This reinforcement will be accomplished by raising the operating pressure of the pipeline from 750 pounds per square inch gauge (psig) to 1,200 psig to provide a greater throughput volume for the existing pipeline. The increase in pressure would be accomplished by installing a booster compressor at the outlet of the existing Rifle Gas Plant. The only pipelines required for this project would be the lead lines to connect the new compressor to the existing gas plant. Two 12 -inch pipelines would be installed from the existing discharge to the Rifle Avon 12 -inch pipeline that is located 200 feet east of the discharge. A suction line would be drawn off the existing Rifle Avon 12 -inch pipeline to the compressor, where the pressure would be increased and the gas discharged via a separate line to the Rifle Avon pipeline. The existing 12 -inch pipeline, operated at 750 psig pressure at the Rifle Gas Plant, has been brought to capacity by growth in Garfield, Eagle, and Pitkin counties. Without construction of this proposed compressor PSCo and RMNG, co-owners of the pipeline, will be unable to continue to provide reliable natural gas service to all the customers served from this pipeline. The Rifle Discharge Compressor Station consists of a utility building, a control building, and the compressor building, where two compressor engines would be installed. At this time, PSCo will design the Rifle Discharge Compressor Station location for two compressor engines; however, in 2002 PSCo intends to install only one engine on the project site. The second engine will be installed later, depending on demand for natural gas. The compressor engine would meet all Colorado Department of Public Health and Environment (CDPHE) air permitting requirements. The compressor engine would also meet a noise specification at the property boundary. A commercial muffler would be installed on the exhaust, and the compressor would be housed in a 35 -foot by 70 -foot building. Because of winter energy demands, the engine will come online as soon as it is installed. The compressor building will be constructed no more than 60 days after the engine is online. The compressor will comply with Colorado Revised Statutes 25-12-103, 1371 -Application for Special Use Permit(July 19.02).doc 7/23/02 1 1 • rNoise Abatement, for industrial zones. I PSCo would like to begin construction of the Rifle Discharge Compressor Station September 15, 2002, so that the Rifle Discharge Compressor Station would be in service by December 1, 2002.

Existing property is 9.7 acres 1.) Plans and specifications for the proposed use including the hours of operation, the amount of vehicles accessing the site on a daily, weekly and/or monthly basis, and 1 the size of any existing or proposed structures that will be utilized in conjunction with the proposed use. Please submit this information in narrative form and be specific. The proposed compressor is being permitted to operate 8,760 hours per year. During normal operation, the compressor station would be unmanned and the site will be 1 accessed by one vehicle per week. Additional trips would be associated with varying maintenance periods as needed. It is anticipated that additional maintenance may occur as many as 6 days per year, with one vehicle per day accessing the site. At a minimum, the site would be accessed by one vehicle per day during annual maintenance period of approximately 1 week. Service vehicles would consist of three-quarter ton pickup trucks. Five vehicles will access the site daily during construction. Construction will occur 12 hours per day, 6 days per week over a 21/2 -month period from September 15, or as soon as the permit is approved, through December 1, 2002. Various vehicles would access the site, depending on the phase of development. A lowboy trailer and semi -truck will transport some equipment to the site and will drop it off for a specified duration, depending on its use. Initially, bulldozers and graders would be used to grade the site. A cement mixer will be used during construction of the foundation, drilling rigs would be used for installation of caissons, a 1,470 -horsepower (hp) crane will be used to install the compressor, and a smaller crane will be used during construction of buildings. A water ' truck would be used to control dust during construction. The number of workers who will access the site during construction would also vary by construction phase, ranging from 5 1371 -Application for Special Use Pennit(July 19.02).doc 2 7/23/02 1 to 20 laborers. Most of the workers would commute from Grand Junction, Colorado. Currently, there is no compression at this location. The existing structures at the Rifle I Gas Plant are used to remove hydrocarbons from natural gas. Proposed structures for the Rifle Discharge Compressor Station include: 1 > Compressor Building, which would be 35 feet wide, 70 feet long, and 20 feet high ➢ Utility Building, which would be 10 feet wide, 10 feet long, and 8 feet high. ➢ Control Building, which would be 10 feet wide, 20 feet long, and 8 feet high The compressor and utility buildings will be located within the existing 3.5 -acre fenced area as shown on Figure 1. The proposed facilities would occupy approximately '/2 acre on the west side of the existing Rifle Gas Plant. The buildings will be metal modular ' structures rated for the rain and snow load for the geographic area. Buildings will be painted desert beige or some other color as recommended by Garfield County. The buildings will screened by natural topography on the north. Figure 2, Site Plan, shows ' the location of existing and proposed structures. 2.) If you will be using water or will be treating wastewater in conjunction with the proposed use, please detail the amount of water that would be used and the type of wastewater treatment. If you will be utilizing well water, please attach a copy of the appropriate well permit and any other legal water supply information, including a 1 water allotment contract or an approved water augmentation plan.

PSCo is aware that 10 copies are required to be provided to the Garfield County Department of Building, one copy is submitted at this time. Subsequent copies will be provided at the direction of the planning department. In addition, for your information this is a joint project between Rocky Mountain Natural Gas Company, A subsidiary of Kinder Morgan, Inc. and Public Service Company of Colorado. As a point of clarification, the Company name may be confusing since our utility company name is "branded" as Xcel Energy (TV, news ads, bills, etc.); however, the legal owner and operator of the utility facilities in Colorado is Public Service Company of Colorado. Since Xcel Energy is only the holding company or "brand" for Public Service Company of Colorado, all utility facilities and related land rights, including fee property, easements, permits, etc., are owned by, operated by and held in the name of Public Service Company of Colorado, a Colorado Corporation. The proposed Rifle Discharge Compressor Station would reinforce the existing 12 -inch high-pressure natural gas pipeline that delivers gas between the Rifle Gas Plant and the Edwards Meter Station. This pipeline provides gas to Silt, New Castle, Glenwood Springs, Basalt, Aspen, Gypsum, Eagle, Edwards, Avon, and the Vail Valley. This reinforcement would be accomplished by raising the operating pressure of the pipeline to provide a greater throughput volume for the existing pipeline. The increase in pressure would be achieved by installing a new compressor at the outlet of the existing Rifle Gas Plant. The only pipelines required for this project would be the lead lines to connect the new compressor to the existing gas plant. The Rifle Discharge Compressor Station will reinforce the existing supply systems and allow customers located in the area to continue • • to receive reliable and economical natural gas service. This information is submitted for review, referral, and consideration for approval by the Garfield County Board of County Commissioners and Planning Commission in accordance with C.R. S. 29-20-108.

PERMIT FOR INDUSTRIAL OPERATION 1 5.03.07 Industrial Operations: Industrial Operations, including extraction, processing, 1 fabrication, industrial support facilities, mineral waste disposal, storage, sanitary Landfill, salvage yard, access routes and utility lines, shall be permitted, provided: 1 Public Service Company of Colorado (PSCo) hereby submits the Permit for Industrial Operation Impact Statement. This information is submitted per the requirements of the Garfield County Special Use Permit and as stated in Section 5.03.07 of the Garfield County Zoning Resolution, 1 effective January 2, 1979. The criteria in this section are addressed following the Summary of Application. A Special Use Permit Application is submitted concurrently with this permit, but under separate cover. 1 SUMMARY OF APPLICATION PSCo proposes to construct and operate a natural gas booster compressor station at the existing Rifle Gas Plant owned and operated by PSCo and Rocky Mountain Natural Gas (RMNG) located on private property 2 miles west of Rifle. The proposed compressor station would be called the Rifle Gas Plant Discharge Compressor Station - Rifle Gas Plant, but is also referred to as the Rifle Discharge Compressor Station in this application. A Special Use Permit was approved in 1994 for the existing Rifle Gas Plant. A Special Use Permit was approved in 1994 for the existing Rifle Gas Plant. Figure 1, Site Layout, shows the property and structures located on the property drawn to scale. Figure 2, Site Plan, shows the county and state roadways within a 1 - mile radius of the property. An existing private road would be used for ingress and egress. Figure 3, Vicinity Map, shows the slope of the property. The compressor station would reinforce the existing 12 -inch high-pressure natural gas pipeline 1 that delivers gas between the Rifle Gas Plant and the Edwards Meter Station. This pipeline provides gas to the following communities: Silt, New Castle, Glenwood Springs, Basalt, Aspen, Gypsum, Eagle, Edwards, Avon, and the Vail Valley. This reinforcement would be 1 accomplished by raising the operating pressure of the pipeline from 750 pounds per square inch gauge (psig) to 1,200 psig to provide a greater throughput volume for the existing pipeline. The increase in pressure would be achieved by installing a booster compressor at the outlet of the 1 existing Rifle Gas Plant. The only pipelines required for this project would be the lead lines to connect the new compressor to the existing gas plant. Two 12 -inch pipelines would be installed from the existing discharge to the Rifle Avon 12 -inch pipeline that is located 200 feet east of the 1 discharge. A suction line would be drawn off the existing Rifle Avon 12 -inch pipeline to the compressor where the pressure would be increased and the gas would be discharged via a 1 separate line to the Rifle Avon pipeline. The existing 12 -inch pipeline, operated at 750-psig pressure at the Rifle Gas Plant, has been brought to capacity by growth in Garfield, Eagle, and Pitkin counties. Without construction of 1 this proposed compressor PSCo and RMNG, co-owners of the pipeline, would be unable to continue to provide reliable natural gas service to all the customers served from this pipeline. 1 1371 -Permit for Industrial Operation (JuI.19.02).doc 1 1 • • Figure 1 Site Layout 1371 -Permit for Industrial Operation (JuI.19.02).doc 2 1 Figure 2 Site Plan 1 1 1 1 1 1 1371 -Permit for Industrial Operation (JuI.19.02).doc 3 1 Figure 3 Vicinity Map 1 1 1 1 1 1 1 1 1 1371 -Permit for Industrial Operation (JuL19.02).doc 4 The Rifle Discharge Compressor Station would consist of a utility building, a control building, and the compressor building, where two compressor engines are proposed. The proposed compressorstation is designed for two compressor engines; however, in 2002, PSCo intends to install only one engine. The second engine would be installed later, depending on the demand for natural gas. The compressor engine would meet all Colorado Department of Public Health and Environment (CDPHE) air permitting requirements. A commercial muffler would be installed on the exhaust, and the compressor would be housed in a 35 -foot by 70 -foot building. Because of energy demands, the engine would come online as soon as it is installed. The building would be added immediately after the engine is operational. It is anticipated that construction of the building would take to more than 60 days after the compressor comes on line. The compressor would comply with Colorado Revised Statutes 25-12-103, Noise Abatement, for industrial zones during all phases of the Project. PSCo would like to begin construction of the Rifle Discharge Compressor Station September 15, 2002 or as soon as the Project is approved, so that the Rifle Discharge Compressor Station would be in service by December 1, 2002. 5.03.07 Industrial Operations: Industrial Operations, including extraction, processing, fabrication, industrial support facilities, mineral waste disposal, storage, sanitary landfill, salvage yard, access routes and utility lines, shall be permitted, provided: The Rifle Discharge Compressor Station is considered an industrial operation based on the definitions set forth in the county zoning resolution. The Industrial Operations Classification 1 Processing is defined in the zoning resolution: "subject to some special process or treatment, as in the course of manufacture; to change in the physical state or chemical composition of matter; the second step in utilization of a natural resource; examples include petroleum refining, oil shale 1 crushing, retorting and refining, ore smelting, coal crushing and cleaning, saw mills, alfalfa pellets mills, food canning or packing, creation of glass, ceramic or plastic materials, gravel crushing, cement manufacture; concrete batch plants." 1 (1)The applicant forapermit for industrial operations shall prepare and submit to the PPP P P ' Planning Director ten (10) copies of an impact statement on the proposed use describing its location, scope, design and construction schedule, including an explanation of its operational characteristics. One (1) copy of the impact statement shall be filed with the ' County Commissioners by the Planning Director. The impact statement shall address the following: ' (A) Existing lawful use of water through depletion or pollution of surface run-off, stream flow or ground water; ' With the exception of water used for dust control, water would be not required in conjunction with the Rifle Discharge Compressor Station. No well water would be used and no wastewater would be generated. Portable sanitary facilities would be located on the property for the duration of construction activities. A U.S. Environmental Protection Agency (EPA) Phase II Stormwater permit has been 1 1371 -Permit for Industrial Operation (Jul.19.02).doc 5 1 ■ completed and filed with CDPHE. A drainage plan would be designed and implemented to control surface run-off for the project area. The Rifle Discharge Compressor Station would not alter stream flow or groundwater. ■ (B) Impacts on adjacent land from the generation of vapor, dust, smoke, noise, glare or vibration, or other emanations; Vapor would not be generated from the Rifle Discharge Compressor Station. Dust raised during construction of the compressor station would be controlled by water spray. Generator exhaust would vent through a stack and would comply with all CDPHE air permitting requirements. Noise would be abated by enclosing the engine within a 35 -foot by 70 -foot structure and by installing an exhaust muffler on the engine. Although the engine would be operational for a brief period of time (less than 60 days) prior to construction of this building, pre - and post -construction noise levels would be less than 75 decibels on the A -weighted scale (dBA) at the property line and would conform to the requirements set forth for the Industrial Zone, Colorado Revised Statutes. Glare would be mitigated by painting buildings desert beige, or some other color as ■ recommended by Garfield County, so that they blend in with the existing landscape and do not create reflection. Manual building lighting would be installed for safety and security. The lights on the facility would be positioned downward to minimize glare. ■ Vibration is not anticipated at the boundary of the property. The Rifle Discharge Compressor Station would be constructed, operated, and maintained in a technologically ■ sound and safe manner and would not cause vibration beyond the boundary of the property. (C) Impacts on wildlife and domestic animals through the creation of hazardous attractions, alteration of existing native vegetation, blockade of migration routes, ' use patterns or other disruptions; The proposed use would not create impacts to domestic animals. Areas beyond the fence t would either be reclaimed or would remain undisturbed and would be available for grazing. ' Impacts on wildlife would be minimized. The proposed use would not create hazardous attractions and would not block migration routes or create disruptions above and beyond those already created by the existing uses in the area (Rifle Gas Plant and I-70). As shown on Figure 1, the Rifle Discharge Compressor Station area is located on the west portion of the existing Rifle Gas Plant and occupies approximately '/2 acre of the existing 3.5 -acre fenced area of the Rifle Gas Plant. The Rifle Gas Plant consists of a nine -acre ' area, however the 3.5 acre fenced area within the nine -acre parcel is the location of the facilities. All acreage within the fenced area would be graded, graveled, and out of production for wildlife. All other areas beyond the fenced boundary of the project would 1 1371 -Permit for Industrial Operation (Jul.19.02).doc 6 ■ remain undisturbed and would be available for use by wildlife. Noxious weeds would be monitored, treated, and controlled throughout the project area. (D) Affirmatively show the impacts of truck and automobile traffic to and from such uses and their impacts to areas in the County; During normal operation, the compressor station would be unmanned and the site would be accessed by one vehicle per week. During an annual maintenance period of 1 week, the site would be accessed by one vehicle per day. It is assumed that additional maintenance may occur as many as 6 days per year, with one vehicle per day accessing the site. The increase in traffic volume would be insignificant. Increases in carbon 111 monoxide, nitrogen oxides, and particulate matter caused by increased traffic would be minimal. Improvements to streets would not be necessary. The existing road would provide access to the site. No new access road would be constructed. Five vehicles would access the site daily during construction. Construction would occur 12 hours per day, 6 days per week over a 2'/2 month period from September 15 through December 1, 2002. Various vehicles would access the site, depending on the phase of development. A lowboy trailer and semi -truck would transport some equipment to the site and would drop it off for a specified duration, depending on its use. Initially, bulldozers and graders would be used when the site is graded. Cement mixer trucks would be used during construction of the foundation, drilling rigs would be used for installation of caissons, a 1,470 -horsepower (hp) crane would be used to install the compressor, and a smaller crane would be used during construction of buildings. A water truck would be used to control dust during construction. The number of workers who would access the site during construction would also vary by construction phase, and would range from 5 to 20 laborers. (E) That sufficient distances shall separate such use from abutting property which might otherwise be damaged by operations of the proposed use(s); The distance from the proposed compressor building to property boundaries vary. The nearest property line to the proposal compressor building is approximately 200 feet. The compressor would comply with the requirements for industrial zones in Colorado Revised Statutes 25-12-103, Noise Abatement. Maximum permissible noise levels for noise radiating from a property line at a distance of 25 feet or more for industrial zones is established to be greater than 80 dBA during the daytime period of 7 a.m. to 7 p.m. and greater than 75 dBA during the nighttime period from 7 p.m. to 7 a.m. Additionally, the Rifle Discharge Compressor Station would be constructed, operated, and maintained in a technologically sound and safe manner and would not cause vibration beyond the boundary of the property. 1 1 1371 -Permit for Industrial Operation (JuI.19.02).doc 7 • • (F) Mitigation measures proposed for all of the foregoing impacts identified and for the standards identified in Section 5.03.08 of this Resolution Mitigation for the Rifle Discharge Compressor Station consists of the following, by resource: Visual Mitigation: Buildings would be painted desert beige, or some other color as recommended by Garfield County, so that they blend in with the existing landscape and do not create reflection or glare. The lights on the facility would be positioned downward. The Rifle Discharge Compressor Station is also visually buffered by natural topography. Roads would be sprayed with water to mitigate the potential visual and air impacts from dust. Noise Mitigation: The compressor engine would generate noise during the operational phase of the project. This noise would be mitigated by enclosing the engine within a 35 - foot by 70 -foot by 20 -foot structure, and by installing a muffler on the engine's exhaust. At the property line, the noise would conform to the requirements set forth in Colorado Revised Statutes 25-12-103, for industrial zones. Adjacent natural topography will also serve to mitigate noise. Erosion Mitigation: The location would be graded and rehabilitated so that excessive erosion does not occur. A drainage plan would be designed for the Rifle Discharge Compressor Station. Culverts, diversion ditches, and sheet runoff slopes would be built so that water does pool or create gullying on the location. Water runoff would not exceed historical runoff rates, and water quality would adhere to the requirements set forth in the EPA Phase II Storm Water Permit. Noxious weeds would be controlled. Dust Mitigation: Dust generated during construction of the compressor station would be controlled by water spray as needed. Glare: The facilities would be constructed using metal, which can result in glare. The facilities would be painted using earth -tone colors so that they blend with the existing landscape and decrease the potential for glare. Manual building lighting would be installed for safety and security. This lighting is expected to be arranged around the site so that the equipment could be safely operated at night. Vibration: Vibration is not anticipated at the boundary of the property. The Rifle Discharge Compressor Station would be constructed, operated, and maintained in a technologically sound and safe manner and would not cause vibration beyond the boundary of the property. (2) Permits may be granted for those uses with provisions that provide adequate mitigation for the following: (A) A plan for site rehabilitation must be approved by the County 1371 -Permit for Industrial Operation (JuI.19.02).doc 8 1 0 • Commissioners before a permit for conditional or special use would be issued; The proposed site consists of approximately 1/2 acres, within an existing fenced 3.5 -acre area. Noxious weeds would be controlled. In the event construction results in minor surface disturbances beyond the fenced area, the disturbance would be re -seeded as necessary with native seed preferred by the landowner. Gravel would be spread in areas around the equipment. Figure 4, Rehabilitation Plan, shows proposed graveled areas and undisturbed areas area. A drainage plan would also be designed and implemented for the Rifle Discharge Compressor Station. (B) The County Commissioners may require security before a permit for special 1 or conditional use is issued, if required. The applicant shall furnish evidence of a bank commitment of credit, bond, certified check or other security deemed acceptable by the county commissioners in the amount calculated by the County Commissioners to secure the execution of the site rehabilitation plan in workmanlike manner and in accordance with the specification and construction schedule established or approved by the County Commissioners. Such commitments, bond or check shall be payable to and held by the County Commissioners; 1 Financial securities can be provided as required by the County Commissioners if deemed appropriate. 1 (C) Impacts set forth in the impact statement and compliance with the standards contained in Section 5.03.08 of this Resolution. (A. 93-061) See Section 5.03.08 below for additional information. 5.03.08 Industrial Performance Standards: All industrial operations in the County ' shall comply with applicable County, State, and Federal regulations regulating water, air and noise pollution and shall not be conducted in a manner constituting a public nuisance ' or hazard. Operations shall be conducted in such a manner as to minimize heat, dust, smoke, vibration, glare and odor and all other undesirable environmental effects beyond the boundaries of the property in which such uses are located, in accord with the following ' standards; (1) Volume of sound generated shall comply with the standards set forth in the Colorado Revised Statutes at the time any new application is made. (A. 93-061) Noise standards and impacts are typically represented in terms of measured on the A- I weighted scale (dBA). The A -weighted scale provide the best measure of the response of the human ear. 1 1 1371 -Permit for Industrial Operation (JuI.19.02).doc 9 1 TWO NEW J0,000GAL STORAGE TANKS.

This noise would be mitigated by enclosing the engine within a 35 -foot by 70 -foot structure, and by installing a muffler on the engine's exhaust. Because of energy demands, the engine would come online as soon as it is installed. The building would be added no more than 60 days after the engine is on line. At the property line, the noise would be less than 75 dBA and would conform to the requirements for industrial zones set forth in Colorado Revised Statutes. The zones should not be confused with the zoning map by Garfield County. The zoning of the Project Area is "Resource/Lands," which are subclassified into the following zones: plateau, escarpment, talus slopes, gentle slopes, and lower valley floor. The location of the Rifle Discharge Compressor Station falls within the "gentle slopes and lower valley floor." Garfield County has not established noise regulations specific to this zone. (2) Vibration generated: every use shall be so operated that the ground vibration inherently and recurrently generated is not perceptible, without instruments, at any point of any boundary line of the property on which the use is located; The Rifle Discharge Compressor Station would be constructed, operated, and maintained in a technologically sound and safe manner and would not cause vibration beyond the boundary of the property. (3) Emissions of smoke and particulate matter: every use shall be operated so as to comply with all Federal, State and County air quality laws, regulations and standards; During the construction phase of the Rifle Gas Plant Discharge Compressor Station, sources of air pollution would include fugitive dust from vehicle traffic on paved and unpaved surfaces, earth moving, and tailpipe emissions from diesel construction equipment. On the construction site, fugitive dust would be generated from rough grading, excavation, cut -and -fill operations, vehicle traffic on unpaved surfaces, and material storage and handling. Fugitive dust emissions from these activities would be controlled by periodic applications of water. Fugitive dust from construction vehicle traffic on paved surfaces would be minimized by periodic cleaning of the paved road surfaces near the construction area. Tailpipe emissions from diesel -fueled earthmoving and construction equipment may result in a temporary increase in emissions of air pollutants at the location of the compressor station. Dispersal of these pollutants would be augmented by high exhaust velocities and temperatures; thus, ground -level concentrations of these pollutants near the proposed development site would be temporary and minimal. Exhaust would vent through a stack during the operation phase. The design of the compressor engine includes a catalytic converter to control criteria air pollutants including oxides of nitrogen (NOX), carbon monoxide (CO), and non -methane -ethane volatile organic compounds (VOC). An application for an air quality construction permit for the initial 1371 -Permit for Industrial Operation (Ju1.19.02).doc 11 compressor station engine has been filed with CDPHE. The permit application was submitted to CDPHE. Approval of the permit is pending. ' The constructionP ermitting process would address general operational compliance criteria for the compressor engine. This permit review and issue process would ensure that any ' operational air emissions from this compressor engine would comply with Colorado air quality rules. An air permit application would be submitted to CDPHE for construction and operation when it becomes necessary to add the second engine to the compressor station. (4) Emission of heat, glare, radiation and fumes: every use shall be so operated that it does not emit heat, glare, radiation or fumes which substantially interfere with the existing use of adjoining property or which constitutes a public nuisance or hazard. Flaring of gases, aircraft warning signals, reflective painting of storage tanks, or other such operations which may be required by law as safety or air pollution control measures shall be exempted from this provision; Heat: The Rifle Discharge Compressor Station does not generate significant levels of heat. The level of heat is minimal and well below the industrial standard. ' Glare: The facilities would be constructed using metal, which can result in glare. The facilities would be painted using earth -tone colors so that they blend with the existing 1 landscape and decrease the potential for glare. Building lighting would be installed for safety and security. This lighting is expected to be arranged around the site so that the equipment could be safely operated. Radiation: Minimal amounts of radiation will occur during construction of the project. Non Destructive Testing (NDT) of welds on the pipelines are required by the Department of ' Transportation for transportation of natural gas. Such activity involves experienced NDT contractors x-raying pipelines welds. During this time, contractors wear monitors and warning signs are posted on the property in accordance with the required Federal welding procedures regulations. Once the project is in operation, there will be no radiation resulting from the project. 1 Fumes: An application for an air quality permit for the initial compressor station engine has been filed with CDPHE. The permit review and issue process would ensure that any t operational air emissions from this compressor engine would comply with Colorado air quality regulations. No flaring would occur and the project does not require aircraft warning signals. Generator exhaust would vent through a stack, which creates emissions of particulate matter. The Rifle Discharge Compressor Station would comply with all CDPHE air permitting requirements.

PSCo is aware that 10 copies are required to be provided to the Garfield County Department of Building, one copy is submitted at this time. Subsequent copies will be provided at the direction of the planning department. In addition, for your information this is a joint project between Rocky Mountain Natural Gas Company, A subsidiary of Kinder Morgan, Inc. and Public Service Company of Colorado. As a point of clarification, the Company name may be confusing since our utility company name is "branded" as Xcel Energy (TV, news ads, bills, etc.); however, the legal owner and operator of the utility facilities in Colorado is Public Service Company of Colorado. Since Xcel Energy is only the holding company or "brand" for Public Service Company of Colorado, all utility facilities and related land rights, including fee property, easements, permits, etc., are owned by, operated by and held in the name of Public Service Company of Colorado, a Colorado Corporation. The proposed Rifle Discharge Compressor Station would reinforce the existing 12 -inch high-pressure natural gas pipeline that delivers gas between the Rifle Gas Plant and the Edwards Meter Station. This pipeline provides gas to Silt, New Castle, Glenwood Springs, Basalt, Aspen, Gypsum, Eagle, Edwards, Avon, and the Vail Valley. This reinforcement would be accomplished by raising the operating pressure of the pipeline to provide a greater throughput volume for the existing pipeline. The increase in pressure would be achieved by installing a new compressor at the outlet of the existing Rifle Gas Plant. The only pipelines required for this project would be the lead lines to connect the new compressor to the existing gas plant. The Rifle Discharge Compressor Station will reinforce the existing supply systems and allow customers located in the area to continue to receive reliable and economical natural gas service. This information is submitted for review, referral, and consideration for approval by the Garfield County Board of County Commissioners and Planning Commission in accordance with C.R. S. 29-20-108. Please call Robert Acree of Greystone Environmental Consultants at (303) 850-0930 or one of the undersigned if you have any questions or if you need additional information.

PERMIT FOR INDUSTRIAL OPERATION 5.03.07 Industrial Operations: Industrial Operations, including extraction, processing, fabrication, industrial support facilities, mineral waste disposal, storage, sanitary landfill, salvage yard, access routes and utility lines, shall be permitted, provided: Public Service Company of Colorado (PSCo) hereby submits the Permit for Industrial Operation Impact Statement. This information is submitted per the requirements of the Garfield County Special Use Permit and as stated in Section 5.03.07 of the Garfield County Zoning Resolution, effective January 2, 1979. The criteria in this section are addressed following the Summary of Application. A Special Use Permit Application is submitted concurrently with this permit, but under separate cover. SUMMARY OF APPLICATION PSCo proposes to construct and operate a natural gas booster compressor station at the existing Rifle Gas Plant owned and operated by PSCo and Rocky Mountain Natural Gas (RMNG) located on private property 2 miles west of Rifle. The proposed compressor station would be called the Rifle Gas Plant Discharge Compressor Station - Rifle Gas Plant, but is also referred to as the Rifle Discharge Compressor Station in this application. A Special Use Permit was approved in 1994 for the existing Rifle Gas Plant. A Special Use Permit was approved in 1994 for the existing Rifle Gas Plant. Figure 1, Site Layout, shows the property and structures located on the property drawn to scale. Figure 2, Site Plan, shows the county and state roadways within a 1 - mile radius of the property. An existing private road would be used for ingress and egress. Figure 3, Vicinity Map, shows the slope of the property. The compressor station would reinforce the existing 12 -inch high-pressure natural gas pipeline that delivers gas between the Rifle Gas Plant and the Edwards Meter Station. This pipeline provides gas to the following communities: Silt, New Castle, Glenwood Springs, Basalt, Aspen, Gypsum, Eagle, Edwards, Avon, and the Vail Valley. This reinforcement would be accomplished by raising the operating pressure of the pipeline from 750 pounds per square inch gauge (psig) to 1,200 psig to provide a greater throughput volume for the existing pipeline. The increase in pressure would be achieved by installing a booster compressor at the outlet of the existing Rifle Gas Plant. The only pipelines required for this project would be the lead lines to connect the new compressor to the existing gas plant. Two 12 -inch pipelines would be installed from the existing discharge to the Rifle Avon 12 -inch pipeline that is located 200 feet east of the discharge. A suction line would be drawn off the existing Rifle Avon 12 -inch pipeline to the compressor where the pressure would be increased and the gas would be discharged via a separate line to the Rifle Avon pipeline. The existing 12 -inch pipeline, operated at 750-psig pressure at the Rifle Gas Plant, has been brought to capacity by growth in Garfield, Eagle, and Pitkin counties. Without construction of this proposed compressor PSCo and RMNG, co-owners of the pipeline, would be unable to continue to provide reliable natural gas service to all the customers served from this pipeline. 1371 -Permit for Industrial Operation (Jul.19.02).doc 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 ;WO NEW 30,000GAL STORAGE TANKS.

The proposed compressor station is designed for two compressor engines; however, in 2002, PSCo intends to install only one engine. The second engine would be installed later, depending on the demand for natural gas. The compressor engine would meet all Colorado Department of Public Health and Environment (CDPHE) air permitting requirements. A commercial muffler would be installed on the exhaust, and the compressor would be housed in a 35 -foot by 70 -foot building. Because of energy demands, the engine would come online as soon as it is installed. The building would be added immediately after the engine is operational. It is anticipated that construction of the building would take to more than 60 days after the compressor comes on line. The compressor would comply with Colorado Revised Statutes 25-12-103, Noise Abatement, for industrial zones during all phases of the Project. PSCo would like to begin construction of the Rifle Discharge Compressor Station September 15, 2002 or as soon as the Project is approved, so that the Rifle Discharge Compressor Station would be in service by December 1, 2002. 5.03.07 Industrial Operations: Industrial Operations, including extraction, processing, fabrication, industrial support facilities, mineral waste disposal, storage, sanitary landfill, salvage yard, access routes and utility lines, shall be permitted, provided: The Rifle Discharge Compressor Station is considered an industrial operation based on the definitions set forth in the county zoning resolution. The Industrial Operations Classification Processing is defined in the zoning resolution: "subject to some special process or treatment, as in the course of manufacture; to change in the physical state or chemical composition of matter; the second step in utilization of a natural resource; examples include petroleum refining, oil shale crushing, retorting and refining, ore smelting, coal crushing and cleaning, saw mills, alfalfa pellets mills, food canning or packing, creation of glass, ceramic or plastic materials, gravel crushing, cement manufacture; concrete batch plants." (1) The applicant for a permit for industrial operations shall prepare and submit to the Planning Director ten (10) copies of an impact statement on the proposed use describing its location, scope, design and construction schedule, including an explanation of its operational characteristics. One (1) copy of the impact statement shall be filed with the County Commissioners by the Planning Director. The impact statement shall address the following: (A) Existing lawful use of water through depletion or pollution of surface run-off, stream flow or ground water; With the exception of water used for dust control, water would be not required in conjunction with the Rifle Discharge Compressor Station. No well water would be used and no wastewater would be generated. Portable sanitary facilities would be located on the property for the duration of construction activities. A U.S. Environmental Protection Agency (EPA) Phase II Stormwater permit has been 1371 -Permit for Industrial Operation (JuI.19.02).doc 5 1 A • 1 completed and filed with CDPHE. A drainage plan would be designed and implemented to control surface run-off for the project area. The Rifle Discharge Compressor Station ' would not alter stream flow or groundwater. (B) Impacts on adjacent land from the generation of vapor, dust, smoke, noise, glare or vibration, or other emanations; Vapor would not be generated from the Rifle Discharge Compressor Station. Dust raised ' during construction of the compressor station would be controlled by water spray. Generator exhaust would vent through a stack and would comply with all CDPHE air permitting requirements. Noise would be abated by enclosing the engine within a 35 -foot by 70 -foot structure and by installing an exhaust muffler on the engine. Although the engine would be operational for a brief period of time (less than 60 days) prior to construction of this building, pre - and post -construction noise levels would be less than 75 decibels on the A -weighted scale (dBA) at the property line and would conform to the requirements set forth for the 1 Industrial Zone, Colorado Revised Statutes. Glare would be mitigated by painting buildings desert beige, or some other color as ' recommended by Garfield County, so that they blend in with the existing landscape and do not create reflection. Manual building lighting would be installed for safety and security. The lights on the facility would be positioned downward to minimize glare. ' Vibration is not anticipated at the boundary of the property. The Rifle Discharge Compressor Station would be constructed, operated, and maintained in a technologically ' sound and safe manner and would not cause vibration beyond the boundary of the property. 1 (C) Impacts on wildlife and domestic animals through the creation of hazardous attractions, alteration of existing native vegetation, blockade of migration routes, use patterns or other disruptions; The proposed use would not create impacts to domestic animals. Areas beyond the fence would either be reclaimed or would remain undisturbed and would be available for grazing. Impacts on wildlife would be minimized. The proposed use would not create hazardous 1 attractions and would not block migration routes or create disruptions above and beyond those already created by the existing uses in the area (Rifle Gas Plant and I-70). As shown on Figure 1, the Rifle Discharge Compressor Station area is located on the west 1 portion of the existing Rifle Gas Plant and occupies approximately 1/2 acre of the existing 3.5 -acre fenced area of the Rifle Gas Plant. The Rifle Gas Plant consists of a nine -acre area, however the 3.5 acre fenced area within the nine -acre parcel is the location of the ' facilities. All acreage within the fenced area would be graded, graveled, and out of production for wildlife. All other areas beyond the fenced boundary of the project would 1 1371 -Permit for Industrial Operation (Ju1.19.02).doc 6 ' remain undisturbed and would be available for use by wildlife. Noxious weeds would be monitored, treated, and controlled throughout the project area. (D) Affirmatively show the impacts of truck and automobile traffic to and from such uses and their impacts to areas in the County; 1 During normal operation, the compressor station would be unmanned and the site would be accessed by one vehicle per week. During an annual maintenance period of 1 week, ' the site would be accessed by one vehicle per day. It is assumed that additional maintenance may occur as many as 6 days per year, with one vehicle per day accessing the site. The increase in traffic volume would be insignificant. Increases in carbon ' monoxide, nitrogen oxides, and particulate matter caused by increased traffic would be minimal. Improvements to streets would not be necessary. The existing road would provide access to the site. No new access road would be constructed. ' Five vehicles would access the site daily during construction. Construction would occur 12 hours per day, 6 days per week over a 2'/2 month period from September 15 through 1 December 1, 2002. Various vehicles would access the site, depending on the phase of development. A lowboy trailer and semi -truck would transport some equipment to the site and would drop it off for a specified duration, depending on its use. Initially, ' bulldozers and graders would be used when the site is graded. Cement mixer trucks would be used during construction of the foundation, drilling rigs would be used for installation of caissons, a 1,470 -horsepower (hp) crane would be used to install the compressor, and a smaller crane would be used during construction of buildings. A water truck would be used to control dust during construction. The number of workers who would access the site during construction would also vary by construction phase, and ' would range from 5 to 20 laborers. (E) That sufficient distances shall separate such use from abutting property which might otherwise be damaged by operations of the proposed use(s); The distance from the proposed compressor building to property boundaries vary. The nearest property line to the proposal compressor building is approximately 200 feet. The compressor would comply with the requirements for industrial zones in Colorado Revised Statutes 25-12-103, Noise Abatement. Maximum permissible noise levels for ' noise radiating from a property line at a distance of 25 feet or more for industrial zones is established to be greater than 80 dBA during the daytime period of 7 a.m. to 7 p.m. and greater than 75 dBA during the nighttime period from 7 p.m. to 7 a.m. Additionally, the 1 Rifle Discharge Compressor Station would be constructed, operated, and maintained in a technologically sound and safe manner and would not cause vibration beyond the boundary of the property. 1 1 1371 -Permit for Industrial Operation (Ju1.19.02).doc 7 1 (F) Mitigation measures proposed for all of the foregoing impacts identified and for the standards identified in Section 5.03.08 of this Resolution Mitigation for the Rifle Discharge Compressor Station consists of the following, by resource: Visual Mitigation: Buildings would be painted desert beige, or some other color as ' recommended by Garfield County, so that they blend in with the existing landscape and do not create reflection or glare. The lights on the facility would be positioned downward. The Rifle Discharge Compressor Station is also visually buffered by natural topography. Roads would be sprayed with water to mitigate the potential visual and air impacts from dust. ' Noise Mitigation: The compressor engine would generate noise during the operational phase of the project. This noise would be mitigated by enclosing the engine within a 35 - foot by 70 -foot by 20 -foot structure, and by installing a muffler on the engine's exhaust. ' At the property line, the noise would conform to the requirements set forth in Colorado Revised Statutes 25-12-103, for industrial zones. Adjacent natural topography will also serve to mitigate noise. Erosion Mitigation: The location would be graded and rehabilitated so that excessive erosion does not occur. A drainage plan would be designed for the Rifle Discharge 1 Compressor Station. Culverts, diversion ditches, and sheet runoff slopes would be built so that water does pool or create gullying on the location. Water runoff would not exceed historical runoff rates, and water quality would adhere to the requirements set forth in the EPA Phase II Storm Water Permit. Noxious weeds would be controlled. Dust Mitigation: Dust generated during construction of the compressor station would be 1 controlled by water spray as needed. Glare: The facilities would be constructed using metal, which can result in glare. The 1 facilities would be painted using earth -tone colors so that they blend with the existing landscape and decrease the potential for glare. Manual building lighting would be installed for safety and security. This lighting is expected to be arranged around the site 1 so that the equipment could be safely operated at night. Vibration: Vibration is not anticipated at the boundary of the property. The Rifle 1 Discharge Compressor Station would be constructed, operated, and maintained in a technologically sound and safe manner and would not cause vibration beyond the boundary of the property. (2)Permits maybegranted for those uses withprovisions thatprovide adequate mitigation 9 g ' for the following: (A) A plan for site rehabilitation must be approved by the County 1 1371 -Permit for Industrial Operation (Jul.19.02).doc 8 • • Commissioners before a permit for conditional or special use would be issued; ' The proposed site consists of approximately 1/2 acres, within an existing fenced 3.5 -acre area. Noxious weeds would be controlled. In the event construction results in minor surface disturbances beyond the fenced area, the disturbance would be re -seeded as necessary with native seed preferred by the landowner. Gravel would be spread in areas around the equipment. Figure 4, Rehabilitation Plan, shows proposed graveled areas and undisturbed areas area. A drainage plan would also be designed and implemented for the Rifle Discharge Compressor Station. (B) The County Commissioners may require security before a permit for special or conditional use is issued, if required. The applicant shall furnish evidence of a bank commitment of credit, bond, certified check or other security deemed acceptable by the county commissioners in the amount calculated by the County ' Commissioners to secure the execution of the site rehabilitation plan in workmanlike manner and in accordance with the specification and construction schedule established or approved by the County Commissioners. Such commitments, bond or check shall be payable to and held by the County Commissioners; ' Financial securities can be provided as required by the County Commissioners if deemed appropriate. (C) Impacts set forth in the impact statement and compliance with the standards contained in Section 5.03.08 of this Resolution. (A. 93-061) 1 See Section 5.03.08 below for additional information. 5.03.08 Industrial Performance Standards: All industrial operations in the County shall comply with applicable County, State, and Federal regulations regulating water, air and noise pollution and shall not be conducted in a manner constituting a public nuisance or hazard. Operations shall be conducted in such a manner as to minimize heat, dust, 1 smoke, vibration, glare and odor and all other undesirable environmental effects beyond the boundaries of the property in which such uses are located, in accord with the following standards; (1) Volume of sound generated shall comply with the standards set forth in the Colorado Revised Statutes at the time any new application is made. (A. 93-061) Noise standards and impacts are typically represented in terms of measured on the A - weighted scale (dBA). The A -weighted scale provide the best measure of the response of the human ear. 1 1 1371 -Permit for Industrial Operation (Jul.19.02).doc 9 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 NO NEW J0,000GAL STORAGE TANKS.

This noise would be mitigated by enclosing the engine within a 35 -foot by 70 -foot structure, and by installing a muffler on the engine's exhaust. Because of energy demands, the engine would come online as soon as it is installed. The building would be added no more than 60 days after the engine is on line. At the property line, the noise would be less than 75 dBA and would conform to the requirements for industrial zones set forth in Colorado Revised Statutes. ' The zones should not be confused with the zoning map by Garfield County. The zoning of the Project Area is "Resource/Lands," which are subclassified into the following zones: plateau, escarpment, talus slopes, gentle slopes, and lower valley floor. The location of the Rifle Discharge Compressor Station falls within the "gentle slopes and lower valley floor." Garfield County has not established noise regulations specific to this zone. ' (2) Vibration generated: every use shall be so operated that the ground vibration inherently and recurrently generated is not perceptible, without instruments, at any point of any boundary line of the property on which the use is located; The Rifle Discharge Compressor Station would be constructed, operated, and maintained in a technologically sound and safe manner and would not cause vibration beyond the boundary 1 of the property. (3) Emissions of smoke and particulate matter: every use shall be operated so as to comply with all Federal, State and County air quality laws, regulations and standards; During the construction phase of the Rifle Gas Plant Discharge Compressor Station, sources of air pollution would include fugitive dust from vehicle traffic on paved and unpaved surfaces, earth moving, and tailpipe emissions from diesel construction equipment. ' On the construction site, fugitive dust would be generated from rough grading, excavation, cut -and -fill operations, vehicle traffic on unpaved surfaces, and material storage and handling. Fugitive dust emissions from these activities would be controlled by periodic applications of water. Fugitive dust from construction vehicle traffic on paved surfaces would be minimized by periodic cleaning of the paved road surfaces near the construction area. ' Tailpipe emissions from diesel -fueled earthmoving and construction equipment may result in a temporary increase in emissions of air pollutants at the location of the compressor station. 1 Dispersal of these pollutants would be augmented by high exhaust velocities and temperatures; thus, ground -level concentrations of these pollutants near the proposed development site would be temporary and minimal. Exhaust would vent through a stack during the operation phase. The design of the compressor engine includes a catalytic converter to control criteria air pollutants including oxides of nitrogen (NOX), carbon monoxide (CO), and non -methane -ethane volatile organic compounds (VOC). An application for an air quality construction permit for the initial 1 1371 -Permit for Industrial Operation (Jul.19.02).doc 1 1 1 compressor station engine has been filed with CDPHE. The permit application was submitted to CDPHE. Approval of the permit is pending. ' The construction permitting process would address general operational compliance criteria for the compressor engine. This permit review and issue process would ensure that any ' operational air emissions from this compressor engine would comply with Colorado air quality rules. ' An air permit application would be submitted to CDPHE for construction and operation when it becomes necessary to add the second engine to the compressor station. ' (4) Emission of heat, glare, radiation and fumes: every use shall be so operated that it does not emit heat, glare, radiation or fumes which substantially interfere with the existing use of adjoining property or which constitutes a public nuisance or hazard. Flaring of ' gases, aircraft warning signals, reflective painting of storage tanks, or other such operations which may be required by law as safety or air pollution control measures shall be exempted from this provision; Heat: The Rifle Discharge Compressor Station does not generate significant levels of heat. The level of heat is minimal and well below the industrial standard. Glare: The facilities would be constructed using metal, which can result in glare. The /facilities would be painted using earth -tone colors so that they blend with the existing ✓ landscape and decrease the potential for glare. Building lighting would be installed for safety and security. This lighting is expected to be arranged around the site so that the equipment could be safely operated. Radiation: Minimal amounts of radiation will occur during construction of the project. Non Destructive Testing (NDT) of welds on the pipelines are required by the Department of Transportation for transportation of natural gas. Such activity involves experienced NDT contractors x-raying pipelines welds. During this time, contractors wear monitors and warning signs are posted on the property in accordance with the required Federal welding 1 procedures regulations. Once the project is in operation, there will be no radiation resulting from the project. Fumes: An application for an air quality permit for the initial compressor station engine has been filed with CDPHE. The permit review and issue process would ensure that any operational air emissions from this compressor engine would comply with Colorado air quality regulations.
