SITE INFORMATION: Tax ID# 2137-321-00-008; 2.3 acres of a 4312-acre tract LOCATION I ACCESS: Approximately 20 miles NW of Debeque on County Road 211 , generally described being situated in SE Y., SW Y. of Section 36, Township 5 South , Range 98 West of the 61h PM . EXISTING & ADJACENT ZONING: Resource Lands (RL), Open Space (O/S) I. REQUEST This proposal is to modify an existing natural gas compressor facility (originally permitted under the Chevron Piceance Valley Pipeline- Administrative Permit #712207 in 2005) Drilling was never undertaken at the well pad s ite (SR598-36-1); it was converted into the compressor station to gather and transfer natural gas to nearby market lines. The expansion is that of adding a Caterpillar gas-driven compressor and skid , with the goal of increasing capacity. No changes to the COGCC site dimensions are proposed . It is an unmanned facility to be operated remotely. The Applicant states , however, that one daily trip (via pickup truck) will take place with the purpose of inspection I maintenance. The construction phase for the improvements is brief, and the operation on the site will comply with the standards expressed in industrial operations for the mitigation of associated impacts. ) /_j) ~ ~f ;f:;.,,.,,..~"" .. , I 1 orrtt> I/ . ="·-~ ,,..,.-_ .... -... .. f tlO.l\t()tj •• < v/ f:J~r -J QE.'111 Mt~l(D (".l f<l'l'I) ~~~/)"' ..

DESCRIPTION OF THE PROPOSAL The Planning Department received a Special Use Permit (SUP) application for "Processing and Material Handling of Natural Resource" for the installation of one additional natural gas compressor D]Ei~~E~~~;ljE;~~fl~i:t~~= on an existing well pad located on ~ a 4312-acre property owned by Chevron USA, Inc. Located beyond the end of CR 211 north of Debeque, the site includes 2 .23 acres of previously disturbed ground that makes use of an existing well pad (Skinner Ridge 36-1 B) originally permitted in 2005. The well pad was never drilled; rather, it was converted in 2006 into a compressor site (permit #712207.) All areas to be affected are within the well pad site administered by the COGCC and reclamation security is administered by them, as well. The equipment includes a Caterpillar gas-driven compressor and NATCO emission-free dehydrator skid for the purpose of increasing rate/capacity of the gas transmission from the site . Installation at the site will begin upon issuance of the SUP and is expected to take 2-3 weeks. ~ c:i • NON-1\ESIOENTIAI.

ZONING & ADJACENT USES The subject property is zoned Resource Lands (Gentle Slopes and Lower Valley Floor). The type of use requested falls under the definition of "Processing and Material Handling of Natural Resources" which are contemplated as special uses in the Resource Lands (Gentle Slopes and Lower Valley Floor) zone district. SUP: Chevron USA 36-1 B Compressor Station Expansion BOCC-21212009 Page3 Adjacent lands under private and Federal ownership (BLM) include uses such as rangeland grazing, farming, and resource extraction (natural gas drilling). Activities nearby include other industrial operations, and the nearest residence is a Chevron-owned property leased to a cattle operation. Ill. AUTHORITY & APPLICABILITY Pursuant to Section 9.03.04 of The Zoning Resolution of 1978. as amended under which this application is being processed, an application for a Special Use Permit shall be approved or denied by the Board of County Commissioners after holding a public hearing thereon in conformance with all provisions of the Zoning Resolution. IV. REVIEW CRITERIA FOR SPECIAL USE PERMITS (SECTION 5:03) Pursuant to Section 5.03, as listed under the Zone District Regulations, special uses shall conform to all requirements listed there under and elsewhere in the Zoning Resolution, as well as the following standards: 1. Utilities adequate to provide water and sanitation service based on accepted engineering standards and approved by the Board of County Commissioners shall either be in place or shall be constructed in conjunction with the proposed use. Response The compressor station is described as an unmanned facility operated remotely from Chevron USA's Grand Junction office." No water or sanitation services are necessary for the proposed facility; any transient need can be met by existing facilities already permitted nearby. 2. Street improvements adequate to accommodate traffic volume generated by the proposed use and to provide safe, convenient access to the use shall either be in place or shall be constructed in conjunction with the proposed use. Response The application states that during construction the compressor is expected to generate an average of 2-4 pickup truck trips and 2-4 tractor trailer trips per day for equipment delivery. All of the truck travel will be traveling on private roads constructed by the industry or from Debeque on CR 204/CR 211. After construction there will be minimal traffic generated by the operation; its operation will be managed for the most part through the revised communication system from the office in Grand Junction. The road to the Compressor site is an existing road previously reviewed by Garfield County Road & Bridge Department and found to meet County standards (CR 211). Previous comments from Road & Bridge Administrative Foreman Jake Mall stated that the County did SUP: Chevron USA 36-1 B Compressor Station Expansion BOCC-21212009 Page4 not foresee a major increase in traffic flow after the construction period of the project. No improvements to CR 211 were necessary for the initial installation of the compressor on the well pad site, and none are required for the installation of this additional compressor unit. Further, this existing well pad is on an access road previously vacated by Garfield County. 3. Design of the proposed use is organized to minimize impact on and from adjacent uses of land through installation of screen fences or landscape materials on the periphery of the lot and by location of intensively utilized areas, access points, lighting and signs in such a manner as to protect established neighborhood character. Response The property is located in a secluded portion of privately owned property. By its location and topography, it is effectively screened by steep topography. The site is located approximately one-half mile from the nearest residence, that being on Chevron USA property and leased to an individual tending grazing cattle that are part of a lease. The proposed use will have relatively limited visual impact to surrounding properties. It cannot be seen from CR 211. It is situated beyond the end of a dead-end County road vacated by the County, which is used primarily for industrial traffic serving the existing industrial uses in the area with very limited general population traffic. Further, the site itself is situated in an area already characterized by intense industrial activity from the exploration I processing activities. No screening is necessary as it is already screened by steep topography. While no lighting is proposed, any future lighting shall be directed inward and downward. Section 5.03.07 llndustrial Operationsl Pursuant to Section 5.03.07 of the Zoning Resolution, a permit for Industrial Operations requires the submittal of an impact statement on the proposed use describing its location, scope, design and construction schedule, including an explanation of its operational characteristics. The impact statement is required to address the following: (A) Existing lawful use of water through depletion or pollution of surface run-off, stream flow or ground water. Response The facility site has been designed to insure protection of ground water and nearby streams through the development and implementation of a Storm Water Management Plan specific to the area which is contained at the rear of the application. Staff notes that while this plan is not specific to the compressor site, Chevron USA has submitted a larger Storm Water Management Plan for the general area. Further, containment facilities are designed into the facility for any hazardous material stored or used during operations. (BJ Impacts on adjacent land from the generation of vapor, dust, smoke, noise, glare or vibration, or other emanations. Response SUP: Chevron USA 36-/B Compressor Station Expansion BOCC-21212009 Page5 Compressors produce considerable volumes of noise and vibration but whose acceptable levels are regulated by the COGCC Series 800 requirements, and the Colorado Revised Statutes. Noise generated will have very little impact on adjacent properties since the compressor is located in a canyon area that will prevent any sound from traveling, as well as being located well within the boundaries of the subject property far from adjacent properties. The former farmhouses that were purchased with the in-holdings are occupied by hands managing herds of cattle on the site. An estimated acoustic analysis was performed by Cordilleran, Inc. using calculations provided by the manufacturer of the compressor equipment, Caterpillar, and Jim Rose of Universal Compression, Inc. The sound analyses for the compressor indicated that the operations will perform within required 'light industrial standards' on the Chevron-owned property sound (that being 70 db daytime, 65 db evening). The results showed a level of 100 db at 1 meter distance from the operating compressor and an operational level of 60.8 db at a distance of 300 feet. The compressor is not located within 300 feet of any property boundary, and the nearest non-Chevron owned residential location is 5 miles away. Chevron USA shall adhere to the noise standards specified by the Colorado Revised Statutes and the Colorado Oil and Gas Conservation Commission Series 800 rules. Given the remote location of the facility, Staff agrees that noise will not be a nuisance to area residents. While noise attenuation devices are not a requirement of this permit, Staff feels that any addition to the number of operating compressors should include noise attenuation shrouds or enclosure of the units within a structure. This would lessen impacts on workers and animal life in the vicinity of the compressor units, and protect the valuable equipment from the weather. (CJ 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. Response The site is located within winter rangeland for mule deer, elk, and turkey as identified on the Division of Wildlife's wildlife distribution maps. The 2.23-acre site is currently disturbed; the open flat area is taken up with the occupation of the facility, but the riparian zone remains intact. The roadways have been located away from the drainages. Much of the cover and forage is being utilized by a cattle lease. The Applicant has fenced the dumpsters to minimize conflicts with wildlife, and dumpsters containing foodstuffs are emptied more often to prevent the attraction and habituation of black bears. (DJ Affirmatively show the impacts of truck and automobile traffic to and from such uses and their impacts to areas in the County. Response SUP: Chevron USA 36-1 B Compressor Station Expansion BOCC-21212009 Page6 There will be two different phases of the operation, each with differing trip generation. All traffic will travel up County Road 204 to County Road 211. This existing road meets the County's standards, and is presently under a program for surface maintenance performed by Hyland Enterprises to treat fugitive dust, and to maintain surface through grading, sanding and snow-plowing. The initial traffic is related to construction. This will involve the transport of the compressor equipment, construction materials and association personnel. Vehicles range from pickup trucks to semi-trucks with trailers to transport heavy loads, such as compressor and parts. As noted earlier, the compressor facility, once fully operational, is expected to generate limited vehicle trips per day into and out of the facility because most of the monitoring of the compressor's performance will be done remotely. Also as mentioned above, most of this truck travel will be coming from Debeque on CR 211 which is capable of handling the additional trips. There is no proposed increase of occupancy of the site. Staff does not foresee a major increase in traffic flow after the construction period and the additional compressor are on line. No improvements to CR 211 are necessary as a result of this compressor station. (E) That sufficient distances shall separate such use from abutting property which might otherwise be damaged by operations of the proposed use(s). Response The operations at the facility will not involve any abutting property. The proposed facility will not encroach upon existing setbacks or reduce current separation distances to abutting properties. Staff agrees that the existing facility is located well within required setbacks and is sufficiently separated from adjacent properties in all directions. (F) Mitigation measures proposed for all of the foregoing impacts identified and for the standards identified in Section 5.03.08 of this Resolution Special Use 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 Commissioners before a permit for conditional or special use will be issued; Response The application is for a site within the perimeter of an approved COGCC well pad site, and the reclamation is already permitted and administered by that agency. Compliance with all prevailing Colorado Oil and Gas Conservation Commission and Garfield County regulations governing final reclamation shall be a condition of approval. SUP: Chevron USA 36-1 B Compressor Station Expansion BOCC-21212009 Page 7 (BJ 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 specifications and construction schedule established or approved by the County Commissioners. Such commitments, bonds or check shall be payable to and held by the County Commissioners; Response In the past, the Board has required, as a condition of approval that "A sufficient monetary security, determined by the Board of County Commissioners, to ensure rehabilitation of the site once operation has ceased shall be provided by the Applicant." It is unclear at the time of this writing as to whether the former well pad currently exists under a permit security. Proof of permit with the COGCC and adequate financial security shall be a condition of approval. Section 5.03.08 [Industrial Performance Standardsl Pursuant to section 5.03.08 of the Zoning Resolution, 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. (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. (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. (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. (5) Storage area, salvage yard, sanitary landfill and mineral waste disposal areas: (A) Storage of flammable or explosive solids or gases shall be in accordance with accepted standards and laws and shall comply with the national, state and SUP: Chevron USA 36-/B Compressor Station Expansion BOCC-21212009 Page8 local fire codes and written recommendations I comments from the appropriate local protection district regarding compliance with the appropriate codes; (B) At the discretion of the County Commissioners, all outdoor storage facilities may be required to be enclosed by fence, landscaping or wall adequate to conceal such facilities from adjacent property; (CJ No materials or wastes shall be deposited upon a property in such form or manner that they may be transferred off the property by any reasonably foreseeable natural causes or forces; (DJ Storage of Heavy Equipment will only be allowed subject to (A) and (CJ above and the following standards: 1. The minimum lot size is five (5J acres and is not a platted subdivision. 2. The equipment storage area is not placed any closer than 300 ft. from any existing residential dwelling. 3. All equipment storage will be enclosed in an area with screening at least eight (BJ feet in height and obscured from view at the same elevation or lower. Screening may include berming, landscaping, sight obscuring fencing or a combination of any of these methods. 4. Any repair and maintenance activity requiring the use of equipment that will generate noise, odors or glare beyond the property boundaries will be conducted within a building or outdoors during the hours of B a.m. to 6 p.m., Mon.-Fri. 5. Loading and unloading of vehicles shall be conducted on private property and may not be conducted on any public right-of-way. (E) Any storage area for uses not associated with natural resources shall not exceed ten (10) acres in size. (F) Any lighting of storage area shall be pointed downward and inward to the property center and shaded to prevent direct reflection on adjacent property. (6J Water pollution: in a case in which potential hazards exist, it shall be necessary to install safeguards designed to comply with the Regulations of the Environmental Protection Agency before operation of the facilities may begin. All percolation tests or ground water resource tests as may be required by local or State Health Officers must be met before operation of the facilities may begin. Staff Response Should the Board approve the request for the Compressor Station, Staff suggests the industrial performance standards be considered conditions of approval as they are specifically intended to ensure that any industrial use such as the proposed Compressor function in accordance with the proper best management practices and within the parameters of the State statutes. The requirement for screening should not be required as the site is remote and the topography effectively shields the operation from applying an adverse visual impact on adjacent parcels. SUP: Chevron USA 36-1 B Compressor Station Expansion BOCC-21212009 Page9 No storage has been requested as part of the application and none shall be permitted, beyond the compressor unit itself. Section 9.03.05 [Periodic Review of SUPl Pursuant to section 9.03.05 of the Zoning Resolution: Any Special Use Permits may be made subject to a periodic review not less than every six (6) months if required by the County Commissioners. The purpose of such review shall be to determine compliance or noncompliance with any performance requirements associated with the granting of the Special Use Permit. The County Commissioners shall indicate that such a review is required and shall establish the time periods at the time of issuance of a Special Use Permit. Such review shall be conducted in such manner and by such persons as the County Commissioners deem appropriate to make the review effective and meaningful. Upon the completion of each review, the Commissioners may determine that the permit operations are in compliance and continue the permit, or determine the operations are not in compliance and either suspend the permit or require the permittee to bring the operation into compliance by a certain specified date. Such periodic review shall be limited to those performance requirements and conditions imposed at the time of the original issuance of the Special Use Permit. V. RECOMMENDED FINDINGS 1. Proper posting and public notice was provided as required for the hearing before the Board of County Commissioners. 2. The hearing before the Board of County Commissioners was extensive and complete, that all pertinent facts, matters and issues were submitted and that all interested parties were heard at that hearing. 3. The above stated and other reasons, the proposed Special Use Permit has been determined to be in the best interest of the health, safety, morals, convenience, order, prosperity and welfare of the citizens of Garfield County. 4. The application has met the requirements of Special Use (Sections 5:03, 5:03:07, 5:03.08 and 9:03) the Garfield County Zoning Resolution of 1978. as amended. VI.

If we reclaim a pad in the amount of $25,000 and ask the COGCC to release that bond, then we will have to provide the agency with a new bond to cover any new surface disturbance. We have several blanket bonds in place with the COGCC for plugging, surface, facilities, etc ... that are available for review on the COGCC website. This blanket surface bond has been accepted by the BOCC on other applications as proof of financial surety.

Permit No. OBGA 1117 Issuance 1 Colorado Department of Public Health and Environment Air Pollution Control Division ATTACHMENT A: ALTERNATIVE OPERATING SCENARIOS RECIPROCATING INTERNAL COMBUSTION ENGINES December 10, 2008 The following Alternative Operating Scenario (AOS) for the temporary and permanent replacement of natural gas fired reciprocating internal combustion engines has been reviewed in accordance with the requirements of Regulation No. 3., Part A, Section IV.A, Operational Flexibility-Alternative Operating Scenarios, Regulation No. 3, Part B, Construction Permits, and Regulation No. 3, Part D, Major Stationary Source New Source Review and Prevention of Significant Deterioration, and it has been found to meet all applicable substantive and procedural requirements. This permit incorporates and shall be considered a Construction Permit for any engine replacement performed in accordance with this AOS, and the permittee shall be allowed to perform such engine replacement without applying for a revision to this permit or obtaining a new Construction Permit. A. 1 Engine Replacement The following AOS is incorporated into this permit in order to deal with a compressor engine breakdown or periodic routine maintenance and repair of an existing onsite engine that requires the use of either a temporary or permanent replacement engine. "Temporary" is defined as in the same service for 90 operating days or less in any 12 month period. "Permanent" is defined as in the same service for more than 90 operating days in any 12 month period. The 90 days is the total number of days that the engine is in operation. If the engine operates only part of a day, that day shall count as a single day towards the 90-day total. The compliance demonstrations and any periodic monitoring required by this AOS are in addition to any compliance demonstrations or periodic monitoring required by this permit. All replacement engines are subject to all federally applicable and state-only requirements set forth in this permit (including monitoring and record keeping). The results of all tests and the associated calculations required by this AOS shall be submitted to the Division within 30 calendar days of the test or within 60 days of the test if such testing Is required to demonstrate compliance with NSPS or MACT requirements. Results of all tests shall be kept on site for five (5) years and made available to the Division upon request. The permittee shall maintain a log on-site and contemporaneously record the start and stop date of any engine replacement, the manufacturer, date of manufacture, model number, horsepower, and serial number of the engine(s) that are replaced during the term of this permit, and the manufacturer, model number, horsepower, and serial number of the replacement engine. In addition to the log, the permittee shall maintain a copy of all Applicability Reports required under section A.1.2 and make them available to the Division upon request. A.1.1 The permittee may temporarily replace an existing compressor engine that is subject to the emission limits set forth in this permit with an engine that is of the same manufacturer, model, and horsepower or a different manufacturer, model, or horsepower as the existing engine without modifying this permit, so long as the emissions from the temporary replacement engine comply with the emission limitations for the existing permitted engine as determined in section A.2. Measurement of emissions from the temporary replacement engine shall be made as set forth in section A.2. A.1.2 The permittee may permanently replace the existing compressor engine with an engine that is of the same manufacturer, model and horsepower without modifying this permit so long as the emissions from the permanent replacement engine comply with 1) the permitted annual emission limitations for the AIRS ID: 045/1033/002 Page 10 of 15 Chevron USA, Inc. Permit No. OBGA 1117 Issuance 1 Colorado Department of Public Health and Environment Air Pollution Control Division existing engine, 2) any permitted short-term emission limitations for the existing permitted engine, and 3) the applicable emission limitations as set forth in the Applicability Report submitted to the Division with the Air Pollutant Emissios Notice (APEN) for the replacement engine (see http://www.cdohe.state.co.us/ap/oilgaspermitting.html for example applicability report formats). Measurement of emissions from the permanent replacement engine and compliance with the applicable emission limitations shall be made as set forth in section 2.2. An Air Pollutant Emissions Notice (APEN) that includes the specific manufacturer, model and serial number and horsepower of the permanent replacement engine shall be filed with the Division for the permanent replacement engine within 14 calendar days of commencing operation of the replacement engine. The APEN shall be accompanied by the appropriate APEN filing fee, a cover letter explaining that the permittee is exercising an alternative operating scenario and is installing a permanent replacement engine, and a copy of the relevant Applicability Reports for the replacement engine. Example Applicability Reports can be found in at http://www.cdphe.state.co.us/ap/oilgaspermittinq.html. This submittal shall be accompanied by a certification from a person legally authorized to act on behalf of the source indicating that "based on the information and belief formed after reasonable inquiry, the statements and information included in the submittal are true, accurate and complete". This AOS cannot be used for permanent engine replacement of a grandfathered or permit exempt engine or an engine that is not subject to emission limits. · The permittee shall agree to pay fees based on the normal permit processing rate for review of information submitted to the Division in regard to any permanent engine replacement. Nothing in this AOS shall preclude the Division from taking an action, based on any permanent engine replacement(s), for circumvention of any state or federal PSD/NANSR requirement. Additionally, in the event that any permanent engine replacement(s) constitute(s) a circumvention of applicable PSD/NANSR requirements, nothing in this AOS shall excuse the permittee from complying with PSD/NANSR and applicable permitting requirements. A.2 Portable Analyzer Testing Note: In some cases there may be conflicting and/or duplicative testing requirements due to overlapping Applicable Requirements. In those instances, please contact the Division Field Services Unit to discuss streamlining the testing requirements. Note that the testing required by this Condition may be used to satisfy the periodic testing requirements specified by the permit for the relevant time period (i.e. if the permit requires quarterly portable analyzer testing, this test conducted under the AOS will serve as the quarterly test and an additional portable analyzer test is not required for another three months). The permittee may conduct a reference method test, in lieu of the portable analyzer test required by this Condition, If approved in advance by the Division. The permittee shall measure nitrogen oxide (NOX) and carbon monoxide (CO) emissions in the exhaust from the replacement engine using a portable flue gas analyzer within seven (7) calendar days of commencing operation of the replacement engine. All portable analyzer testing required by this permit shall be conducted using the Division's Portable Analyzer Monitoring Protocol (ver March 2006 or newer) as found on the Division's website at: http://www.cdphe.state.co.us/ap/down/portanalyzeproto.pdf Results of the portable analyzer tests shall be used to monitor the compliance status of this unit. AIRS ID: 045/1033/002 Page 11 of 15 Chevron USA, Inc. Permit No. OBGA 1117 Issuance 1 Colorado Department of Public Health and Environment Air Pollution Control Division For comparison with an annual (tons/year) or short term (lbs/unit of time) emission limit, the results of the tests shall be converted to a lb/hr basis and multiplied by the allowable operating hours in the month or year (whichever applies) in order to monitor compliance. If a source is not limited in its hours of operation the test results will be multiplied by the maximum number of hours in the month or year (8760), whichever applies. For comparison with a short-term limit that is either input based (lb/mmBtu), output based (g/hp-hr) or concentration based (ppmvd @ 15% 02) that the existing unit is currently subject to or the replacement engine will be subject to, the results of the test shall be converted to the appropriate units as described in the above-mentioned Portable Analyzer Monitoring Protocol document. If the portable analyzer results indicate compliance with both the NOX and CO emission limitations, in the absence of credible evidence to the contrary, the source may certify that the engine is in compliance with both the NOX and CO emission limitations for the relevant time period. Subject to the provisions of C.R.S. 25-7-123.1 and In the absence of credible evidence to the contrary, if the portable analyzer results fail to demonstrate compliance with either the NOX or CO emission limitations, the engine will be considered to be out of compliance from the date of the portable analyzer test until a portable analyzer test indicates compliance with both the NOX and CO emission limitations or until the engine is taken offline. A.3 Applicable Regulations for Permanent Engine Replacements A.3.1 Reasonably Available Control Technology (RACT): Reg 3, Part B § 11.D.2 All permanent replacement engines that are located in an area that is classified as attainmenUmaintenance or nonattalnment must apply Reasonably Available Control Technology (RACT) for the pollutants for which the area is attainmenUmaintenance or nonattainment. Note that both VOC and NOX are precursors for ozone. RACT shall be applied for any level of emissions of the pollutant for which the area is in attainmenUmaintenance or nonattainment, except as follows: In the Denver Metropolitan PM10 attainmenUmaintenance area, RACT applies to PM10 at any level of emissions and to NOX and 802, as precursors to PM10, if the potential to emit of NOX or 802 exceeds 40 tons/yr. For purposes of this AOS, the following shall be considered RACT for natural-gas fired reciprocating internal combustion engines: voe: CO: NOX: 802: PM10: The emission limitations in NSPS JJJJ The emission limitations in NSPS JJJJ The emission limitations in NSPS JJJJ Use of natural gas as fuel Use of natural gas as fuel As defined in 40 CFR Part 60 Subparts GG (§ 60.331) and 40 CFR Part 72 (§ 72.2), natural gas contains 20.0 grains or less of total sulfur per 100 standard cubic feet.

A.3.5 Additional Sources AIRS ID: 045/10331002 Page 14 of 15 Chevron USA, Inc. Permit No. OBGA 1117 Issuance 1 Colorado Department of Public Health and Environment Air Pollution Control Division The replacement of an existing engine with a new engine is viewed by the Division as the installation of a new emissions unit, not "routine replacement" of an existing unit. The AOS is therefore essentially an advanced construction permit review. The AOS cannot be used for additional new emission points for any site; an engine that is being installed as an entirely new emission point and not as part of an AOS- approved replacement of an existing onsite engine has to go through the appropriate Construction/Operating permitting process prior to installation.
