Permitted Activities 1.1 The Cheyenne Plains Gas Pipeline Company, LLC, Cheyenne Plains Compressor Station is a natural gas compression facility as defined under Standard Industrial Classification 4922. This facility is a mainline compressor station. Its main function is to compress and transmit natural gas from the Wyoming area east into Kansas. The sources addressed in this operating permit include three (3) natural gas fired combustion turbines driving natural gas compressors. The facility also includes a CO2 Treatment Plant, which consists of a triethylene glycol dehydrator and amine treatment unit. Emissions from the glycol dehydrator still (regenerator)vent and flash tank and emissions from the amine unit flash tank are routed to a flare to reduce VOC emissions. The amine unit regenerator vent is equipped with a SulfaTreat H2S control system to reduce H2S emissions. There are also two (2) 43.79 MMBtu/hr natural gas fired heaters associated with the amine unit and an emergency generator that are included in Section II of the permit as significant emission units. The Cheyenne Plains Compressor Station was constructed in 2004 at the site of an existing mainline compressor station (Cheyenne Station), whose main function is to compress and transmit natural gas from the Wyoming area to the Colorado Front Range area. As such the two facilities are considered a single source for purposes of Prevention of Significant Deterioration (PSD)review requirements and Title V permitting requirements. Equipment associated with the Cheyenne Compressor Station is addressed in a separate Title V operating permit(95OPWE090). The facility is located in Weld County on Highway 85 at Section 5, T11N, R66W (- 4 miles North of Rockport). The area in which the plant operates is designated as attainment for all criteria pollutants. There are two affected states within 50 miles of the plant: Wyoming and Nebraska. The following Federal Class I designated area is within 100 kilometers of the plant: Rocky Mountain National Park. 1.2 Until such time as this permit expires or is modified or revoked, the Source is allowed to discharge air pollutants from this facility in accordance with the requirements, limitations, and conditions of this permit. 1.3 The Operating Permit incorporates the applicable requirements contained in the underlying construction permits, and does not affect those applicable requirements, except as modified during review of the application or as modified subsequent to permit issuance using the modification procedures found in Colorado Regulation No. 3, Part C. These Part C procedures meet all applicable substantive New Source Review requirements of Part B. Any revisions made using the provisions of Regulation No. 3, Part C shall become new applicable requirements for purposes of this Operating Permit and shall survive reissuance. This permit incorporates the applicable requirements (except as noted in Section II) from the following construction permits: 03WE0910, 03WE0913, 03WE0916 and 04WE1390. 1.4 All conditions in this permit are enforceable by the United States Environmental Protection Agency (EPA), Colorado Air Pollution Control Division (hereinafter Division) and its agents, and citizens unless otherwise specified. State-only enforceable conditions are: Permit Condition Number(s): Section IV, Conditions 3.g (last paragraph), 14, 18 (as noted) & 30 (as noted); and Section II, Condition 7.1 & 7.2. Operating Permit#05OPWE281 First Issued: October 1, 2007 Renewed: DRAFT Air Pollution Control Division Cheyenne Plains Gas Pipeline Company, LLC Colorado Operating Permit Cheyenne Plains Compressor Station Permit# 05OPWE281 Page 2 1.5 All information gathered pursuant to the requirements of this permit is subject to the Recordkeeping and Reporting requirements listed under Condition 22 of the General Conditions in Section IV of this permit. Either electronic or hard copy records are acceptable. 2. Alternative Operating Scenarios for Turbines—version 01/23/2013 2.1 Routine Turbine Component Replacements The following physical or operational changes to the turbines in this permit are not considered a modification for purposes of NSPS GG, major stationary source NSR/PSD, or Regulation No. 3, Part B. Note that the component replacement provisions apply ONLY to those turbines subject to NSPS GG. Neither pre-GG turbines nor post GG turbines (i.e. KKKK turbines) can use those provisions. In the event that EPA promulgates amendments to Subparts GG and/or KKKK that further define or alter the definition of component replacements that will not trigger modifications,the provisions of those rules shall supersede the component replacement provisions listed below. 2.1.1 Replacement of stator blades, turbine nozzles,turbine buckets, fuel nozzles, combustion chambers, seals, and shaft packings, provided that they are of the same design as the original. 2.1.2 Changes in the type or grade of fuel used, if the original gas turbine installation, fuel nozzles, etc. were designed for its use. 2.1.3 An increase in the hours of operation (unless limited by a permit condition) 2.1.4 Variations in operating loads within the engine design specification. 2.1.5 Any physical change constituting routine maintenance, repair, or replacement. Turbines undergoing any of the above changes are subject to all federally applicable and state-only requirements set forth in this permit(including monitoring and record keeping), and shall be subject to any shield afforded by this permit. If replacement of any of the components listed in (1) or(5) above results in a change in serial number for the turbine, a letter explaining the action as well as a revised APEN and appropriate filing fee shall be submitted to the Division within 30 days of the replacement. Note that the repair or replacement of components must be of genuinely the same design. Except in accordance with the Alternate Operating Scenario set forth below,the Division does not consider that this allows for the entire replacement(or reconstruction) of an existing turbine with an identical new one or one similar in design or function. Rather,the Division considers the repair or replacements to encompass the repair or replacement of components at a turbine with the same (or functionally similar) components. 2.2 Alternative Operating Scenarios The following Alternative Operating Scenario (AOS) for the temporary and permanent replacement of combustion turbines and turbine components 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 Operating Permit#05OPWE281 First Issued: October 1, 2007 Renewed: DRAFT Air Pollution Control Division Cheyenne Plains Gas Pipeline Company, LLC Colorado Operating Permit Cheyenne Plains Compressor Station Permit# 05OPWE281 Page 3 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 turbine or turbine component replacement performed in accordance with this AOS, and the permittee shall be allowed to perform such turbine or turbine component replacement without applying for a revision to this permit or obtaining a new Construction Permit. 2.2.1 General Requirements for Turbine Replacements The following AOS is incorporated into this permit in order to deal with a turbine breakdown or periodic routine maintenance and repair of an existing onsite turbine that requires the use of a temporary or permanent replacement turbine. The definitions of"Temporary" and"Permanent" for each permitted unit are defined in Condition 2.2.7. The compliance demonstrations required by this AOS are in addition to any compliance demonstrations or periodic monitoring required by this permit. All replacement turbines are subject to all federally applicable and state-only requirements set forth in this permit(including monitoring and record keeping), and shall be subject to any shield afforded by this permit. 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 the NSPS requirements. Results of all tests shall be kept on site for five (5) years and made available to the Division upon request. 2.2.2 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 turbine using a portable flue gas analyzer within seven (7) calendar days of commencing operation of the replacement turbine. All portable analyzer testing required by this permit shall be conducted using the most current version of the Division's Portable Analyzer Monitoring Protocol as found on the Division's website. Results of the portable analyzer tests shall be used to monitor the compliance status of this unit. Operating Permit#05OPWE281 First Issued: October 1, 2007 Renewed: DRAFT Air Pollution Control Division Cheyenne Plains Gas Pipeline Company, LLC Colorado Operating Permit Cheyenne Plains Compressor Station Permit# 05OPWE281 Page 4 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% O2)that the existing unit is currently subject to or the replacement turbine 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 turbine 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 turbine 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 turbine is taken offline. 2.2.3 Recordkeeping Requirements for Turbine Replacements The permittee shall maintain a log on-site to contemporaneously record the start and stop date of any turbine replacement,the manufacturer and serial number of the turbine(s)that are replaced during the term of this permit, and the manufacturer and serial number of the replacement turbine. 2.2.4 Specific Requirements for Temporary Replacements The permittee may temporarily replace an existing turbine covered by this permit as specified in Condition 2.2.7 with the exact make and model turbine without modifying this permit so long as the replacement turbine complies with the emission limitations and other requirements applicable to the original turbine as well as any new applicable requirements for the replacement turbine. Measurement of emissions from the temporary replacement turbine shall be made as set forth in Condition 2.2.2. The permittee may temporarily replace a grandfathered or permit exempt turbine or a turbine that is not subject to emission limits without modifying this permit. In this circumstance, potential annual emissions of NOX and CO from the temporary replacement turbine must be less than or equal to the potential annual emissions of NOX and CO from the original grandfathered or permit exempt turbine or for the turbine that is not subject to emission limits, as determined by applying appropriate emission factors (e.g. AP-42 or manufacturer's emission factors). 2.2.5 Specific Requirements for Permanent Replacements Operating Permit#05OPWE281 First Issued: October 1, 2007 Renewed: DRAFT Air Pollution Control Division Cheyenne Plains Gas Pipeline Company, LLC Colorado Operating Permit Cheyenne Plains Compressor Station Permit# 05OPWE281 Page 5 The permittee may permanently replace an existing turbine covered by this permit as specified in Condition 2.2.7 with the exact make and model turbine without modifying this permit so long as the replacement turbine complies with the emission limitations and other requirements applicable to the original turbine as well as any new applicable requirements for the replacement turbine. Measurement of emissions from the temporary replacement turbine shall be made as set forth in Condition 2.2.2. This AOS cannot be used for permanent turbine replacement of a grandfathered or permit exempt turbine or a turbine that is not subject to emission limits. This AOS cannot be used in areas designated as non-attainment or attainment/maintenance for VOC, CO,NOX SO2 and PMio. The AOS cannot be used for the permanent replacement of an entire turbine at any source that is an existing major stationary source for a regulated NSR Pollutant unless the existing turbine has federally enforceable emission limits that are below the significance levels in Reg 3, Part D, II.A.44. This AOS cannot be used for the permanent replacement of an entire turbine at any source where: (1)the facility-wide potential to emit of CO2e is equal to or greater than 100,000 tpy of CO2e, and (2)the originally permitted turbine does not have a CO2e emission limit below 75,000 tpy CO2e. In the absence of a numerical CO2e limit,the PTE of CO2e should be based on 8760 hours per year of operation and emission factors from AP-42 Chapter 3.1, 40 CFR Part 75, and/or other factors approved by the Division. Nothing in this AOS shall preclude the Division from taking an action, based on any permanent turbine replacement(s), for circumvention of any state or federal PSD/NANSR requirement. Additionally, in the event that any permanent turbine 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. 2.2.5.1 Turbines Relocated into Colorado from Outside of Colorado Note that under the provisions of Regulation No. 6, Part B, Section I.B., as referenced in Part A, the following turbines that are exempt from federal NSPS requirements based on dates of construction, reconstruction or relocation that occurred outside of the State of Colorado will become subject to NSPS requirements after relocation into the State as follows: a. Replacement Units Previously Exempt from NSPS GG This condition applies to units that originally commenced construction outside of Colorado prior to October 3, 1977 and have not been reconstructed or modified after October 3, 1977. If these units were previously installed within the State of Colorado during the applicability dates of NSPS Subpart GG (October 3, 1977 — February 18, 2005), they will be subject to Subpart GG upon relocation into the State of Colorado. The applicable requirements of Subpart GG shall be determined based on the date on Operating Permit#05OPWE281 First Issued: October 1, 2007 Renewed: DRAFT Air Pollution Control Division Cheyenne Plains Gas Pipeline Company, LLC Colorado Operating Permit Cheyenne Plains Compressor Station Permit# 05OPWE281 Page 6 which the unit was previously installed within the State of Colorado. If these units were not previously installed within the State of Colorado during the applicability dates of NSPS Subpart GG, they will be subject to the requirements for new units under Subpart KKKK upon commencement of construction in Colorado. b. Units Subject to NSPS Subpart GG This condition applies to units that originally commenced construction outside of Colorado after October 3, 1977 but prior to February 18, 2005 and have not been reconstructed or modified after February 18, 2005. These units will remain subject to NSPS Subpart GG upon relocation into Colorado, and the applicable requirements under Subpart GG shall not be changed or re-determined based on the date of relocation into Colorado. c. Units subject to NSPS Subpart KKKK This condition applies to units that originally commenced construction outside of Colorado after February 18,2005. These units will remain subject to NSPS Subpart KKKK upon relocation into Colorado, and the applicable requirements under Subpart KKKK shall not be changed or re-determined based on the date of relocation into Colorado. 2.2.5.2 Air Pollutant Emission Notice (APEN) Submittals An APEN that includes the specific manufacturer, model, and serial number of any permanent replacement turbine shall be filed with the Division for the permanent replacement turbine within 14 calendar days of commencing operation of the replacement turbine. The APEN shall be accompanied by the appropriate APEN filing fee and a cover letter explaining that the permittee is exercising an alternative operating scenario and is installing a permanent replacement turbine. 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 turbine replacement. The owner or operator shall include, with the APEN, a regulatory applicability analysis to address the requirements of the replacement unit. At a minimum,the applicability analysis shall include: • An analysis of any requirements applicable to the replacement turbine that differ from those applicable to the permitted unit. Applicable requirements include, but are not limited to, Federal NSPS, MACT and/or Colorado Air Quality Control Commission regulations. For example, if an original unit that qualifies as a reconstructed gas turbine subject to an NSPS KKKK NOx limit of 150 ppm is replaced with a Subpart KKKK unit that has not been modified or reconstructed, the NOx limit of the replacement unit will be 42 ppm. The analysis should also address any testing, monitoring, recordkeeping and reporting differences between the original and replacement units. Operating Permit#05OPWE281 First Issued: October 1, 2007 Renewed: DRAFT Air Pollution Control Division Cheyenne Plains Gas Pipeline Company, LLC Colorado Operating Permit Cheyenne Plains Compressor Station Permit# 05OPWE281 Page 7 • The applicability determination shall list the most recent date that the turbine was modified or reconstructed as per the definitions in 40 CFR §§60.2 and 60.14. If the turbine has never been modified or reconstructed,the applicability determination shall include a statement to verify that no modifications or reconstructions have occurred. • The applicability determination shall also list the most recent date that the turbine was overhauled, and an explanation of whether the overhaul qualifies or does not qualify as a modification or reconstruction. Supporting documentation, including cost estimates shall be submitted for those that do not qualify as reconstructions. • The applicability analysis must be certified by either 1) for Operating Permits, a Responsible Official as defined in Colorado Regulation No. 3, Part A, Section I.B.38, or 2) for Construction and General Permits,the person legally authorized to act on behalf of the source. This signed certification document must be packaged with the documents being submitted. The certification shall include the following statement: I have reviewed this certification in its entirety and, based on information and belief formed after reasonable inquiry, I certify that the statements and information contained in this certification are true, accurate and complete. 2.2.6 Additional Sources The replacement of an existing turbine with a new turbine 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; a turbine that is being installed as an entirely new emission point and not as part of an AOS-approved replacement of an existing onsite turbine has to go through the appropriate Construction/Operating permitting process prior to installation.

"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), and shall be subject to any shield afforded by this permit. 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. 3.1.1 The permittee may temporarily replace a grandfathered or permit exempt engine or an engine that is not subject to emission limits without modifying this permit. In this circumstance, potential annual emissions of NOX and CO from the temporary replacement engine must be less than or equal to the potential annual emissions of NOX and CO from the original grandfathered or permit exempt engine or for the engine that is not subject to emission limits, as determined by applying appropriate emission factors (e.g. AP-42 or manufacturer's emission factors).

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.

Prevention of Significant Deterioration (PSD) 4.1 This facility is located in an area designated attainment for all pollutants. It is categorized as a major stationary source (Potential to Emit> 250 Tons/Year for NOR, CO and VOC). Future modifications at this facility resulting in a significant net emissions increase (see Reg 3, Part D, Sections II.A.27 and 44) for any pollutant as listed in Regulation No. 3, Part D, Section II.A.44 or a modification which is major by itself(i.e. a Potential to Emit of>250 TPY of any pollutant listed in Regulation No. 3, Part D, Section II.A.44) may result in the application of the PSD review requirements. 4.2 The following Operating Permit is associated with this facility for purposes of determining the applicability of PSD regulations: 4.2.1 95OPWE090 (Cheyenne Compressor Station) 5. Accidental Release Prevention Program (112(r)) 5.1 Based on the information provided by the Source,this facility is not subject to the provisions of the Accidental Release Prevention Program in Section 112(r) of the Federal Clean Air Act(CAA). 6. Compliance Assurance Monitoring (CAM) 6.1 The following emission points at this facility use a control device to achieve compliance with an emission limitation or standard to which they are subject and have pre-control emissions that exceed or are equivalent to the major source threshold. They are therefore subject to the provisions of the CAM program as set forth in 40 CFR Part 64, as adopted by reference in Colorado Regulation No. 3, Part C, Section XIV: The glycol dehydrator is not subject to CAM since at the time the CAM plan was required the Title V permit specified a continuous compliance determination method (40 CFR Part 64 § 64.2(b)(1)(vi), as adopted by reference in Colorado Regulation No. 3, Part C, Section XIV).

Test Method 22 in appendix A of part 60 of this chapter shall be used to determine the compliance of flares with the visible emission provisions of this part. The observation period is 2 hours and shall be used according to Method 22. (40 CFR Part 63 Subpart A § 63.11(b)(4)) Compliance with the visible emission requirements shall be monitored by conducting a visible emission observation monthly when the flare is operating. Monthly observations shall last a minimum of five minutes. If no visible emissions are present during this observation, in the absence of credible evidence to the contrary,the flare will be considered in compliance with the above visible emissions requirement. If visible emissions are present during the monthly reading, a two (2)hour observation shall be conducted in accordance with Method 22 to determine if the flare is in compliance with the above visible emissions requirement. If visible emissions are present for five minutes or less (total) during the two-hour observation,then the flare shall be deemed in compliance. If visible emissions are present for more than five minutes (total) during the two-hour observation, then the flare shall be deemed out of compliance with the above visible emissions requirement. Subject to the provisions of C.R.S. § 25-7-123.1 and in the absence of credible evidence to the contrary, exceedance of the visible emission requirement shall be considered to exist from the time a Method 22 reading is taken that shows the flare is out of compliance (as defined above) until a Method 22 reading is taken that shows the flare is in compliance (as defined above). 3.10.5 Flares shall be operated with a flame present at all times. The presence of a flare pilot flame shall be monitored using a thermocouple or any other equivalent device to detect the presence of a flame (40 CFR Part 63 Subpart A § 63.11(b)(5))). The device must meet the specific requirements specified in Conditions 3.8.32 and 3.8.33. Records of the times and duration of all periods of pilot flame outages, and estimated emissions shall be maintained and made available Operating Permit#05OPWE281 First Issued: October 1, 2007 Renewed: DRAFT Air Pollution Control Division Cheyenne Plains Gas Pipeline Company, LLC Colorado Operating Permit Cheyenne Plains Compressor Station Permit# 05OPWE281 Page 39 to the Division upon request. Estimated emissions shall be used as specified in Condition 3.4.1 to monitor compliance with the VOC and benzene emission limitation in Condition 3.4. 3.10.6 Flares shall be used only with the net heating value of the gas being combusted being 11.2 MJ/scm (300 Btu/scf) or greater if the flare is steam-assisted or air-assisted; or with the net heating value of the gas being combusted being 7.45 MJ/scm (200 Btu/scf) or greater if the flare is nonassisted (40 CFR Part 63 Subpart A § 63.11(b)(6)(ii)). The net heating value of the gas being combusted shall be calculated using the equation specified in 40 CFR R Part 63 Subpart A § 63.11(b)(6)(ii). 3.10.7 Air-assisted flares shall be designed and operated with an exit velocity less than the velocity, Vmax, as determined by 40 CFR Part 63 Subpart A § 63.11(b)(8) (40 CFR Part 63 Subpart A § 63.11(b)(8)). The actual exit velocity of a flare shall be determined by dividing by the volumetric flow rate of gas being combusted (in units of emission standard temperature and pressure), as determined by Test Method 2, 2A, 2C, or 2D in appendix A to 40 CFR part 60 of this chapter, as appropriate, by the unobstructed (free) cross-sectional area of the flare tip (40 CFR Part 63 Subpart A § 63.11(b)(7)(i)). 3.10.8 The permittee shall maintain records from the September 2005 performance test indicating compliance with the requirements of Conditions 3.10.6 and 3.10.7. The results of the monitoring required under 3.10.4 shall be used to assess compliance with the requirements in Conditions 3.10.6 and 3.10.7. 3.11 Emissions from the amine unit regenerator(still)vent shall be routed through a closed vent system to the Sulfa Treat H2S control system prior to being emitted. The SulfaTreat H2S control system shall be operated and maintained to reduce H2S emissions from the amine unit regenerator(still) vent by 75%or greater(Colorado Construction Permit 03WE0916). The outlet H2S concentration shall be continuously monitored in order to determine when the SulfaTreat material must be replaced. The permittee shall keep records from the manufacturer which indicate the H2S outlet concentration level that requires replacement of the SulfaTreat material. In the absence of credible evidence to the contrary, compliance with the 75%reduction requirement shall be presumed provided the SulfaTreat unit and associated H2S monitoring system are operated and maintained in accordance with manufacturer's recommendations and good engineering practices. Records of the times and duration of all periods the SulfaTreat unit was not operating and estimated emissions shall be maintained and made available to the Division upon request. Estimated emissions shall be used as specified in Condition 3.4.2 to monitor compliance with the H2S emission limitations in Condition 3.4. 3.12 Supplemental fuel consumed in the flare shall be monitored and recorded monthly in a log that is available to the Division upon request. The amount of supplemental fuel consumed shall be used to calculate monthly fuel consumption for each heater as required by Condition 2.3 (Colorado Construction Permit 03WE0913, as modified under the provisions of Section I, Condition 1.3, to allow for use of a combined fuel meter instead of individual fuel meters for the hot oil heaters).

As such, this engine is only subject to the initial notification requirements the National Emissions Standards for Hazardous Air Pollutants requirements of Regulation No. 8, Part E, Subpart ZZZZ (40 CFR Part 63, Subpart ZZZZ), for Stationary Reciprocating Internal Combustion Engines. The requirements below reflect the rule language in 40 CFR Part 63 Subpart ZZZZ as of the latest revisions to 40 CFR Part 63 Subpart ZZZZ published in the Federal Register on February 27, 2014. However, if revisions to this Subpart are published at a later date, the owner or operator is subject to the requirements contained in the revised version of 40 CFR Part 63 Subpart ZZZZ. The D.C. Circuit Court issued a mandate on May 4, 2016 for vacatur for certain requirements allowing emergency engines to operate for limited hours for demand response. Upon issuance of the mandate, 40 CFR Part §63.6640(f)(2)(ii) - (iii) (Conditions 4.4.1.2.b and 4.4.1.2.c) have no legal effect. Operation of emergency engines is limited to emergency situations specified in §63.6640(O(1) (Condition 4.4.1.1); maintenance checks and readiness testing for a limited number of hours per year as specified in §63.6640(f)(2)(i) (Condition 4.4.1.2.a); and certain non-emergency situations for a limited number of hours per year as specified in §63.6640(f)(3) (Condition 4.4.1.3). See EPA memorandum dated April 15, 2016 regarding"Guidance on Vacatur of RICE NESHAP and NSPS Provisions for Emergency Engines" for more information. It should be noted that additional revisions to the requirements to 40 CFR Part 63 Subpart ZZZZ are expected to be made in response to issues related to legal action associated with the allowable hours of operation provisions for emergency engines regarding engines used for demand response. If such revisions are finalized prior to issuance of the permit,they will be included in the permit. As of the date of this permit issuance [DATE],the requirements in 40 CFR Part 63 Subpart ZZZZ promulgated after July 1, 2007 have not been adopted into Colorado Regulation No. 8, Part E and are therefore not state-enforceable. In the event that these requirements are adopted into Colorado Regulations,they will become state-enforceable. 4.4.1 If you own or operate an emergency stationary RICE, you must operate the emergency stationary RICE according to the requirements in Conditions 4.4.1.1 through 4.4.1.3. In order for the engine to be considered an emergency stationary RICE under this subpart, any operation other than emergency operation, maintenance and testing, emergency demand response, and operation in non-emergency situations for 50 hours per year, as described in Condition 4.4.1.3, is prohibited. If you do not operate the engine according to the requirements in Conditions 4.4.1.1 through 4.4.1.3,the engine will not be considered an emergency engine under this subpart and must meet all requirements for non-emergency engines (§63.6640(f)). 4.4.1.1 There is no time limit on the use of emergency stationary RICE in emergency situations. 4.4.1.2 You may operate your emergency stationary RICE for any combination of the purposes specified in Condition 4.4.1.2.a below for a maximum of 100 hours per calendar year. Any operation for non-emergency situations as allowed by 4.4.1.3 counts as part of the 100 hours per calendar year allowed by this Condition 4.4.1.2. Operating Permit#05OPWE281 First Issued: October 1, 2007 Renewed: DRAFT Air Pollution Control Division Cheyenne Plains Gas Pipeline Company, LLC Colorado Operating Permit Cheyenne Plains Compressor Station Permit# 05OPWE281 Page 42 a. Emergency stationary RICE may be operated for maintenance checks and readiness testing,provided that the tests are recommended by federal, state or local government, the manufacturer,the vendor,the regional transmission organization or equivalent balancing authority and transmission operator, or the insurance company associated with the engine. The owner or operator may petition the Administrator for approval of additional hours to be used for maintenance checks and readiness testing, but a petition is not required if the owner or operator maintains records indicating that federal, state, or local standards require maintenance and testing of emergency RICE beyond 100 hours per calendar year. b. Emergency stationary RICE may be operated for emergency demand response for periods in which the Reliability Coordinator under the North American Electric Reliability Corporation(NERC) Reliability Standard EOP-002-3, Capacity and Energy Emergencies (incorporated by reference, see § 63.14), or other authorized entity as determined by the Reliability Coordinator, has declared an Energy Emergency Alert Level 2 as defined in the NERC Reliability Standard EOP-002- 3. c. Emergency stationary RICE may be operated for periods where there is a deviation of voltage or frequency of 5 percent or greater below standard voltage or frequency. 4.4.1.3 Emergency stationary RICE located at major sources of HAP may be operated for up to 50 hours per calendar year in non-emergency situations. The 50 hours of operation in non-emergency situations are counted as part of the 100 hours per calendar year for maintenance and testing and emergency demand response provided in Condition 4.4.1.2. The 50 hours per year for non-emergency situations cannot be used for peak shaving or non-emergency demand response, or to generate income for a facility to supply power to an electric grid or otherwise supply power as part of a financial arrangement with another entity. The records maintained as required by Condition 4.2 shall be used to monitor the hours and type of operation for this emergency engine.

Portable Monitoring (06/26/2014) Emission measurements of nitrogen oxides (NOx) and carbon monoxide (CO) shall be conducted quarterly using a portable flue gas analyzer. At least one calendar month shall separate the quarterly tests. Note that if the engine is operated for less than 100 hrs in any quarterly period, then the portable monitoring requirements do not apply. 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: https://www.colorado.aov/pacific/cdphe/portable-analyzer-monitoring-protocol Results of the portable analyzer tests shall be used to monitor the compliance status of this unit. For comparison with an annual or short term 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. 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. For comparison with the emission rates/factors,the emission rates/factors determined by the portable analyzer tests and approved by the Division shall be converted to the same units as the emission rates/factors in the permit. If the portable analyzer tests shows that either the NOx or CO emission rates/factors are greater than the relevant ones set forth in the permit, and in the absence of subsequent testing results to the contrary (as approved by the Division), the permittee shall apply for a modification to this permit to reflect, at a minimum, the higher emission rate/factor within 60 days of the completion of the test. Results of all tests conducted shall be kept on site and made available to the Division upon request.

Performance Testing The owner or operator of any air pollution source shall,upon request of the Division,conduct performance test(s) and furnish the Division a written report of the results of such test(s)in order to determine compliance with applicable emission control regulations. Performance test(s)shall be conducted and the data reduced in accordance with the applicable reference test methods unless the Division: (i) specifies or approves,in specific cases,the use of a test method with minor changes in methodology; (ii) approves the use of an equivalent method; (iii) approves the use of an alternative method the results of which the Division has determined to be adequate for indicating where a specific source is in compliance;or (iv) waives the requirement for performance test(s)because the owner or operator of a source has demonstrated by other means to the Division's satisfaction that the affected facility is in compliance with the standard. Nothing in this paragraph shall be construed to abrogate the Commission's or Division's authority to require testing under the Colorado Revised Statutes,Title 25,Article 7,and pursuant to regulations promulgated by the Commission. Compliance test(s)shall be conducted under such conditions as the Division shall specify to the plant operator based on representative performance of the affected facility.The owner or operator shall make available to the Division such records as may be necessary to determine the conditions of the performance test(s).Operations during period of startup,shutdown,and malfunction shall not constitute representative conditions of performance test(s)unless otherwise specified in the applicable standard. The owner or operator of an affected facility shall provide the Division thirty days prior notice of the performance test to afford the Division the opportunity to have an observer present.The Division may waive the thirty day notice requirement provided that arrangements satisfactory to the Division are made for earlier testing. The owner or operator of an affected facility shall provide,or cause to be provided,performance testing facilities as follows: (i) Sampling ports adequate for test methods applicable to such facility; (ii) Safe sampling platform(s); (iii) Safe access to sampling platform(s);and (iv) Utilities for sampling and testing equipment. Each performance test shall consist of at least three separate runs using the applicable test method.Each run shall be conducted for the time and under the conditions specified in the applicable standard.For the purpose of determining compliance with an applicable standard,the arithmetic mean of results of at least three runs shall apply.In the event that a sample is accidentally lost or conditions occur in which one of the runs must be discontinued because of forced shutdown,failure of an irreplaceable portion of the sample train,extreme meteorological conditions,or other circumstances beyond the owner or operator's control,compliance may,upon the Division's approval,be determined using the arithmetic mean of the results of the two other runs. Nothing in this section shall abrogate the Division's authority to conduct its own performance test(s)if so warranted.

Affirmative Defense Provision for Excess Emissions during Malfunctions An affirmative defense to a claim of violation under these regulations is provided to owners and operators for civil penalty actions for excess emissions during periods of malfunction.To establish the affirmative defense and to be relieved of a civil penalty in any action to enforce an applicable requirement,the owner or operator of the facility must meet the notification requirements below in a timely manner and prove by a preponderance of evidence that: (i) The excess emissions were caused by a sudden,unavoidable breakdown of equipment,or a sudden, unavoidable failure of a process to operate in the normal or usual manner,beyond the reasonable control of the owner or operator; (ii) The excess emissions did not stem from any activity or event that could have reasonably been foreseen and avoided,or planned for,and could not have been avoided by better operation and maintenance practices; (iii) Repairs were made as expeditiously as possible when the applicable emission limitations were being exceeded; (iv) The amount and duration of the excess emissions(including any bypass)were minimized to the maximum extent practicable during periods of such emissions; (v) All reasonably possible steps were taken to minimize the impact of the excess emissions on ambient air quality; (vi) All emissions monitoring systems were kept in operation(if at all possible); (vii) The owner or operator's actions during the period of excess emissions were documented by properly signed,contemporaneous operating logs or other relevant evidence; (viii) The excess emissions were not part of a recurring pattern indicative of inadequate design,operation,or maintenance; (ix) At all times,the facility was operated in a manner consistent with good practices for minimizing emissions. This section is intended solely to be a factor in determining whether an affirmative defense is available to an owner or operator,and shall not constitute an additional applicable requirement;and (x) During the period of excess emissions,there were no exceedances of the relevant ambient air quality standards established in the Commissions' Regulations that could be attributed to the emitting source. The owner or operator of the facility experiencing excess emissions during a malfunction shall notify the division verbally as soon as possible, but no later than noon of the Division's next working day, and shall submit written notification following the initial occurrence of the excess emissions by the end of the source's next reporting period. The notification shall address the criteria set forth above. The Affirmative Defense Provision contained in this section shall not be available to claims for injunctive relief. The Affirmative Defense Provision does not apply to failures to meet federally promulgated performance standards or emission limits, including, but not limited to,new source performance standards and national emission standards for hazardous air pollutants.The affirmative defense provision does not apply to state implementation plan(sip)limits or permit limits that have been set taking into account potential emissions during malfunctions, including, but not necessarily limited to, certain limits with 30-day or longer averaging times, limits that indicate they apply during malfunctions,and limits that indicate they apply at all times or without exception. e. Circumvention Clause A person shall not build,erect,install,or use any article,machine,equipment,condition,or any contrivance,the use of which,without resulting in a reduction in the total release of air pollutants to the atmosphere,reduces or conceals Operating Permit#05OPWE281 First Issued: October 1, 2007 Renewed: DRAFT Air Pollution Control Division Cheyenne Plains Gas Pipeline Company, LLC Colorado Operating Permit Cheyenne Plains Compressor Station Permit# 05OPWE281 Page 52 an emission which would otherwise constitute a violation of this regulation.No person shall circumvent this regulation by using more openings than is considered normal practice by the industry or activity in question. f. Compliance Certifications For the purpose of submitting compliance certifications or establishing whether or not a person has violated or is in violation of any standard in the Colorado State Implementation Plan,nothing in the Colorado State Implementation Plan shall preclude the use,including the exclusive use,of any credible evidence or information,relevant to whether a source would have been in compliance with applicable requirements if the appropriate performance or compliance test or procedure had been performed.Evidence that has the effect of making any relevant standard or permit term more stringent shall not be credible for proving a violation of the standard or permit term. When compliance or non-compliance is demonstrated by a test or procedure provided by permit or other applicable requirement,the owner or operator shall be presumed to be in compliance or non-compliance unless other relevant credible evidence overcomes that presumption. g. Affirmative Defense Provision for Excess Emissions During Startup and Shutdown An affirmative defense is provided to owners and operators for civil penalty actions for excess emissions during periods of startup and shutdown.To establish the affirmative defense and to be relieved of a civil penalty in any action to enforce an applicable requirement,the owner or operator of the facility must meet the notification requirements below in a timely manner and prove by a preponderance of the evidence that: (i) The periods of excess emissions that occurred during startup and shutdown were short and infrequent and could not have been prevented through careful planning and design; (ii) The excess emissions were not part of a recurring pattern indicative of inadequate design,operation or maintenance; (iii) If the excess emissions were caused by a bypass(an intentional diversion of control equipment),then the bypass was unavoidable to prevent loss of life,personal injury,or severe property damage; (iv) The frequency and duration of operation in startup and shutdown periods were minimized to the maximum extent practicable; (v) All possible steps were taken to minimize the impact of excess emissions on ambient air quality; (vi) All emissions monitoring systems were kept in operation(if at all possible); (vii) The owner or operator's actions during the period of excess emissions were documented by properly signed,contemporaneous operating logs or other relevant evidence;and, (viii) At all times,the facility was operated in a manner consistent with good practices for minimizing emissions. This subparagraph is intended solely to be a factor in determining whether an affirmative defense is available to an owner or operator,and shall not constitute an additional applicable requirement. The owner or operator of the facility experiencing excess emissions during startup and shutdown shall notify the Division verbally as soon as possible,but no later than two(2)hours after the start of the next working day,and shall submit written quarterly notification following the initial occurrence of the excess emissions. The notification shall address the criteria set forth above. The Affirmative Defense Provision contained in this section shall not be available to claims for injunctive relief. The Affirmative Defense Provision does not apply to State Implementation Plan provisions or other requirements that derive from new source performance standards or national emissions standards for hazardous air pollutants, or any other federally enforceable performance standard or emission limit with an averaging time greater than twenty-four Operating Permit#05OPWE281 First Issued: October 1, 2007 Renewed: DRAFT Air Pollution Control Division Cheyenne Plains Gas Pipeline Company, LLC Colorado Operating Permit Cheyenne Plains Compressor Station Permit# 05OPWE281 Page 53 hours.In addition,an affirmative defense cannot be used by a single source or small group of sources where the excess emissions have the potential to cause an exceedance of the ambient air quality standards or Prevention of Significant Deterioration(PSD)increments. In making any determination whether a source established an affirmative defense,the Division shall consider the information within the notification required above and any other information the Division deems necessary,which may include,but is not limited to,physical inspection of the facility and review of documentation pertaining to the maintenance and operation of process and air pollution control equipment. 4. Compliance Requirements Regulation No.3,5 CCR 1001-5,Part C, III.C.9.,V.C.11.& 16.d.and§25-7-122.1(2),C.R.S. a. The permittee must comply with all conditions of the Operating Permit.Any permit noncompliance relating to federally-enforceable terms or conditions constitutes a violation of the federal act,as well as the state act and Regulation No.3.Any permit noncompliance relating to state-only terms or conditions constitutes a violation of the state act and Regulation No.3,shall be enforceable pursuant to state law,and shall not be enforceable by citizens under§304 of the federal act.Any such violation of the federal act,the state act or regulations implementing either statute is grounds for enforcement action,for permit termination,revocation and reissuance or modification or for denial of a permit renewal application. b. It shall not be a defense for a permittee in an enforcement action or a consideration in favor of a permittee in a permit termination,revocation or modification action or action denying a permit renewal application that it would have been necessary to halt or reduce the permitted activity in order to maintain compliance with the conditions of the permit. c. The permit may be modified,revoked,reopened,and reissued,or terminated for cause.The filing of any request by the permittee for a permit modification,revocation and reissuance,or termination,or any notification of planned changes or anticipated noncompliance does not stay any permit condition,except as provided in§§ X.and XI.of Regulation No.3,Part C. d. The permittee shall furnish to the Air Pollution Control Division,within a reasonable time as specified by the Division,any information that the Division may request in writing to determine whether cause exists for modifying, revoking and reissuing,or terminating the permit or to determine compliance with the permit.Upon request,the permittee shall also furnish to the Division copies of records required to be kept by the permittee, including information claimed to be confidential.Any information subject to a claim of confidentiality shall be specifically identified and submitted separately from information not subject to the claim. e. Any schedule for compliance for applicable requirements with which the source is not in compliance at the time of permit issuance shall be supplemental,and shall not sanction noncompliance with,the applicable requirements on which it is based. f.

Appendix B — Reporting Requirements and Definitions Please note that, pursuant to 113(c)(2) of the federal Clean Air Act, any person who knowingly: (A) Makes any false material statement,representation,or certification in,or omits material information from, or knowingly alters, conceals, or fails to file or maintain any notice, application, record, report, plan, or other document required pursuant to the Act to be either filed or maintained (whether with respect to the requirements imposed by the Administrator or by a State); (B) Fails to notify or report as required under the Act; or (C) Falsifies,tampers with, renders inaccurate, or fails to install any monitoring device or method required to be maintained or followed under the Act shall, upon conviction, be punished by a fine pursuant to title 18 of the United States Code, or by imprisonment for not more than 2 years, or both. If a conviction of any person under this paragraph is for a violation committed after a first conviction of such person under this paragraph,the maximum punishment shall be doubled with respect to both the fine and imprisonment. The Source must comply with all conditions of this operating permit. Any permit noncompliance constitutes a violation of the Act and is grounds for enforcement action; for permit termination, revocation and reissuance, or modification; or for denial of a permit renewal application. The Part 70 Operating Permit program requires three types of reports to be filed for all permits. All required reports must be certified by a responsible official. Report#1: Monitoring Deviation Report (due at least every six months) For purposes of this operating permit, the Division is requiring that the monitoring reports are due every six months unless otherwise noted in the permit. All instances of deviations from permit monitoring requirements must be clearly identified in such reports. For purposes of this operating permit, monitoring means any condition determined by observation, by data from any monitoring protocol, or by any other monitoring which is required by the permit as well as the recordkeeping associated with that monitoring. This would include, for example, fuel use or process rate monitoring, fuel analyses, and operational or control device parameter monitoring. Report#2: Permit Deviation Report(must be reported "promptly") In addition to the monitoring requirements set forth in the permits as discussed above, each and every requirement of the permit is subject to deviation reporting. The reports must address deviations from permit requirements, including those attributable to malfunctions as defined in this Appendix, the. probable cause of such deviations, and any corrective actions or preventive measures taken. All deviations from any term or condition of the permit are required to be summarized or referenced in the annual compliance certification. Operating Permit#05OPWE281 First Issued: October 1, 2007 Renewed: DRAFT Air Pollution Control Division Colorado Operating Permit Appendix B Compliance Certification Report Page 67 For purposes of this operating permit, "malfunction" shall refer to both emergency conditions and malfunctions. Additional discussion on these conditions is provided later in this Appendix. ,For purposes of this operating permit, the Division is requiring that the permit deviation reports are due as set forth in General Condition 21. Where the underlying applicable requirement contains a definition of prompt or otherwise specifies a time frame for reporting deviations,that definition or time frame shall govern. For example, quarterly Excess Emission Reports required by an NSPS or Regulation No. 1, Section IV. In addition to the monitoring deviations discussed above, included in the meaning of deviation for the purposes of this operating permit are any of the following: (1) A situation where emissions exceed an emission limitation or standard contained in the permit; (2) A situation where process or control device parameter values demonstrate that an emission limitation or standard contained in the permit has not been met; (3) A situation in which observations or data collected demonstrates noncompliance with an emission limitation or standard or any work practice or operating condition required by the permit; or, (4) A situation in which an excursion or exceedance as defined in 40CFR Part 64 (the Compliance Assurance Monitoring(CAM)Rule) has occurred. (only if the emission point is subject to CAM) For reporting purposes, the Division has combined the Monitoring Deviation Report with the Permit Deviation Report. All deviations shall be reported using the following codes: 1 = Standard: When the requirement is an emission limit or standard 2 =Process: When the requirement is a production/process limit 3=Monitor: When the requirement is monitoring 4=Test: When the requirement is testing 5=Maintenance: When required maintenance is not performed 6=Record: When the requirement is recordkeeping 7=Report: When the requirement is reporting 8=CAM: A situation in which an excursion or exceedance as defined in 40CFR Part 64 (the Compliance Assurance Monitoring (CAM) Rule) has occurred. 9=Other: When the deviation is not covered by any of the above categories Report#3: Compliance Certification (annually, as defined in the permit) Submission of compliance certifications with terms and conditions in the permit, including emission limitations, standards, or work practices, is required not less than annually. Compliance Certifications are intended to state the compliance status of each requirement of the permit over the certification period. They must be based, at a minimum, on the testing and monitoring methods specified in the permit that were conducted during the relevant time period. In addition, if the owner or Operating Permit#05OPWE281 First Issued: October 1, 2007 Renewed: DRAFT Air Pollution Control Division Colorado Operating Permit Appendix B Compliance Certification Report Page 68 operator knows of other material information (i.e. information beyond required monitoring that has been specifically assessed in relation to how the information potentially affects compliance status),that information must be identified and addressed in the compliance certification. The compliance certification must include the following: • The identification of each term or condition of the permit that is the basis of the certification; • Whether or not the method(s) used by the owner or operator for determining the compliance status with each permit term and condition during the certification period was the method(s) specified in the permit. Such methods and other means shall include, at a minimum,the methods and means required in the permit. If necessary,the owner or operator also shall identify any other material information that must be included in the certification to comply with section 113(c)(2) of the Federal Clean Air Act, which prohibits knowingly making a false certification or omitting material information; • The status of compliance with the terms and conditions of the permit, and whether compliance was continuous or intermittent. The certification shall identify each deviation and take it into account in the compliance certification.Note that not all deviations are considered violations.' • Such other facts as the Division may require, consistent with the applicable requirements to which the source is subject,to determine the compliance status of the source. The Certification shall also identify as possible exceptions to compliance any periods during which compliance is required and in which an excursion or exceedance as defined under 40 CFR Part 64 (the Compliance Assurance Monitoring(CAM) Rule) has occurred(only for emission points subject to CAM). Note the requirement that the certification shall identify each deviation and take it into account in the compliance certification. Previously submitted deviation reports, including the deviation report submitted at the time of the annual certification, may be referenced in the compliance certification. For example, given the various emissions limitations and monitoring requirements to which a source may be subject, a deviation from one requirement may not be a deviation under another requirement which recognizes an exception and/or special circumstances relating to that same event. Operating Permit#05OPWE281 First Issued: October 1, 2007 Renewed: DRAFT Air Pollution Control Division Colorado Operating Permit Appendix B Compliance Certification Report Page 69 Startup, Shutdown, Malfunctions and Emergencies, Understanding the application of Startup, Shutdown, Malfunctions and Emergency Provisions, is very important in both the deviation reports and the annual compliance certifications. Startup, Shutdown, and Malfunctions Please note that exceedances of some New Source Performance Standards (NSPS) and Maximum Achievable Control Technology (MACT) standards that occur during Startup, Shutdown or Malfunctions may not be considered to be non-compliance since emission limits or standards often do not apply unless specifically stated in the NSPS. Such exceedances must, however, be reported as excess emissions per the NSPS/MACT rules and would still be noted in the deviation report. In regard to compliance certifications, the permittee should be confident of the information related to those deviations when making compliance determinations since they are subject to Division review. The concepts of Startup, Shutdown and Malfunctions also exist for Best Available Control Technology (BACT) sources, but are not applied in the same fashion as for NSPS and MACT sources. Emergency Provisions Under the Emergency provisions of Part 70 certain operational conditions may act as an affirmative defense against enforcement action if they are properly reported. DEFINITIONS Malfunction (NSPS) means any sudden, infrequent, and not reasonably preventable failure of air pollution control equipment, process equipment, or a process to operate in a normal or usual manner. Failures that are caused in part by poor maintenance or careless operation are not malfunctions. Malfunction (SIP) means any sudden and unavoidable failure of air pollution control equipment or process equipment or unintended failure of a process to operate in a normal or usual manner. Failures that are primarily caused by poor maintenance, careless operation, or any other preventable upset condition or preventable equipment breakdown shall not be considered malfunctions. Emergency means any situation arising from sudden and reasonably unforeseeable events beyond the control of the source, including acts of God, which situation requires immediate corrective action to restore normal operation, and that causes the source to exceed a technology-based emission limitation under the permit, due to unavoidable increases in emissions attributable to the emergency. An emergency shall not include noncompliance to the extent caused by improperly designed equipment, lack of preventative maintenance, careless or improper operation, or operator error.

Purpose This document establishes the basis for decisions made regarding the applicable requirements, emission factors, monitoring plan and compliance status of emission units covered by the renewed Operating Permit for the Cheyenne Plains Compressor Station. The previous Operating Permit for this facility was issued on October 1, 2007, was renewed on April 1, 2014 and expired on April 1, 2019. However, since a timely and complete renewal application was submitted, under Colorado Regulation No. 3, Part C, Section IV.C all of the terms and conditions of the existing permit shall not expire until the renewal operating permit is issued and any previously extended permit shield continues in full force and operation. This document is designed for reference during the review of the proposed permit by the EPA, the public, and other interested parties. The conclusions made in this report are based on information provided in the renewal application submitted on March 30, 2018, comments on the draft permit submitted on [date], previous inspection reports and various email correspondence. Please note that copies of the Technical Review Document for the original permit and any Technical Review Documents associated with subsequent modifications of the original Operating Permit may be found in the Division files as well as on the Division website at www.colorado.gov/cdphe/airTitleV. This narrative is intended only as an adjunct for the reviewer and has no legal standing. Any revisions made to the underlying construction permits associated with this facility made in conjunction with the processing of this operating permit application have been reviewed in accordance with the requirements of Regulation No. 3, Part B, Construction Permits, and have been found to meet all applicable substantive and procedural requirements. This operating permit incorporates and shall be considered to be a combined construction/operating permit for any such revision, and the permittee shall be allowed to operate under the revised conditions upon issuance of this operating permit without applying for a revision to this permit or for an additional or revised construction permit. 123/0051 Page 1 of 13 Cheyenne Plains Gas Pipeline Company, LLC—Cheyenne Plains Compressor Station Operating Permit No. 05OPWE281 Technical Review Document—Renewal Operating Permit II. Description of Source The Cheyenne Plains Gas Pipeline Company, LLC, Cheyenne Plains Compressor Station is a natural gas compression facility as defined under Standard Industrial Classification 4922. This facility is a mainline compressor station. Its main function is to compress and transmit natural gas from the Wyoming area east into Kansas. The sources addressed in this operating permit include three (3) natural gas fired combustion turbines driving natural gas compressors. The facility also includes a CO2 Treatment Plant, which consists of a triethylene glycol dehydrator and amine treatment unit. Emissions from the glycol dehydrator still (regenerator) vent and flash tank and emissions from the amine unit flash tank are routed to a flare to reduce VOC emissions. The amine unit regenerator vent is equipped with a SulfaTreat H2S control system to reduce H2S emissions. There are also two (2) 43.79 MMBtu/hr natural gas fired heaters associated with the amine unit and an emergency generator that are included in Section II of the permit as significant emission units. The Cheyenne Plains Compressor Station was constructed in 2004 at the site of an existing mainline compressor station (Cheyenne Station), whose main function is to compress and transmit natural gas from the Wyoming area to the Colorado Front Range area. As such the two facilities are considered a single source for purposes of Prevention of Significant Deterioration (PSD) review requirements and Title V permitting requirements. Equipment associated with the Cheyenne Compressor Station is addressed in a separate Title V operating permit (95OPWE090). The facility is located in Weld County on Highway 85 at Section 5, T11 N, R66W (— 4 miles North of Rockport). The area in which the plant operates is designated as attainment for all criteria pollutants. Prevention of Significant Deterioration (PSD) This facility is located in an area designated attainment for all pollutants. It is categorized as a major stationary source (Potential to Emit ≥ 250 Tons/Year for NOx, CO and VOC). Future modifications at this facility resulting in a significant net emissions increase (see Reg 3, Part D, Sections II.A.27 and 44) for any pollutant as listed in Regulation No. 3, Part D, Section II.A.44 or a modification which is major by itself(i.e. a Potential to Emit of≥ 250 TPY of any pollutant listed in Regulation No. 3, Part D, Section II.A.44) may result in the application of the PSD review requirements. Emissions All emissions listed below remain unchanged from the previous TRD. Emissions for the Dehydrator Reboiler Burners are based on manufacturer emission factors for NOx and CO, and AP-42 Chapter 1.4 (7/1998) for all other pollutants. Potential to emit at the facility (in tons/yr) is shown in the table below: 123/0051 Page 2 of 13 Cheyenne Plains Gas Pipeline Company, LLC—Cheyenne Plains Compressor Station Operating Permit No. 05OPWE281 Technical Review Document—Renewal Operating Permit Facility Wide Emissions (95OPWE090 and 05OPWE281) Potential to Emit Actual Emissions2 Pollutant 95OPWE090 05OPWE281 Facility PM' 35.23 11.96 47.19 5.60 PMio' 35.23 11.96 47.19 5.60 SO2' 1.33 3.44 4.77 1.53 NO. 624.3 112.52 736.82 94.46 CO 262.8 158.11 420.91 60.10 VOC 291.3 58.37 349.67 40.83 HAPs 60.7 14.14 74.80 7.63 'Emissions for each emission unit are typically below the APEN de minimis level, so emission limits have generally not been included in the construction permits and/or Title V permit. 2Actual emissions are from the Division's Inventory System for the year 2018. 05OPWE281 Emissions Potential to Emit Emission Unit PM PM,o SO2 NO.

Applicable Requirements Accidental Release Program — 112(r) Section 112(r) of the Clean Air Act mandates a new federal focus on the prevention of chemical accidents. Sources subject to these provisions must develop and implement risk management programs that include hazard assessment, a prevention program, and an emergency response program. They must prepare and implement a Risk Management Plan (RMP) as specified in the Rule 123/0051 Page 3 of 13 Cheyenne Plains Gas Pipeline Company, LLC—Cheyenne Plains Compressor Station Operating Permit No. 05OPWE281 Technical Review Document—Renewal Operating Permit Based on the information provided by the applicant, this facility is not subject to the provisions of the Accidental Release Prevention Program (Section 112(r) of the Federal Clean Air Act). Compliance Assurance Monitoring (CAM) The following emission points at this facility use a control device to achieve compliance with an emission limitation or standard to which they are subject and have pre-control emissions that exceed or are equivalent to the major source threshold. They are therefore subject to the provisions of the CAM program as set forth in 40 CFR Part 64 as adopted by reference into Colorado Regulation No. 3, Part C, Section XIV: None. The glycol dehydrator is not subject to CAM since at the time the CAM plan was required the Title V permit specified a continuous compliance determination method (40 CFR Part 64 § 64.2(b)(1)(vi), as adopted by reference in Colorado Regulation No. 3, Part C, Section XIV). All other units at the facility either have uncontrolled emissions below CAM applicability thresholds, or do not use devices considered to be control devices for the purposes of CAM applicability. See previous versions of TRDs for more information on CAM. Hazardous Air Pollutants (HAPs) This facility is major for HAPs. Potential to emit of total HAPs for both the Cheyenne Plains Compressor Station (05OPWE281) and the Cheyenne Compressor Station (95OPWE090) combined is above the major source threshold of 25 tpy. 40 CFR 63 Subpart YYYY - National Emission Standards for Hazardous Air Pollutants for Stationary Combustion Turbines Each turbine is considered to be a "new" turbine (commenced construction after January 14, 2003) under Subpart YYYY. However, §63.6095(d) notes that standards for new or reconstructed gas-fired lean premix and diffusion flame turbines are stayed until EPA takes final action to require compliance, and only initial notification requirements apply. An initial notification was submitted for turbines CG-7101 and CG- 7201 on June 15, 2005 and an initial notification was submitted for turbine CG-7301 on April 4, 2006. At the time of this permit issuance, the provisions in §63.6095(d) are still current, therefore, no Subpart YYYY requirements are included in this renewal permit. 40 CFR Part 63 Subpart ZZZZ—National Emissions Standards for Hazardous Air Pollutants for Stationary Reciprocating Internal Combustion Engines EG-6141 is a new emergency engine greater than 500 hp located at a major source of HAP. As such, it is exempt from all requirements under Subpart ZZZZ except for initial reporting requirements (§ 63.6590(b)(1)(i)). The initial notification for this unit was submitted on December 13, 2004. 123/0051 Page 4 of 13 Cheyenne Plains Gas Pipeline Company, LLC—Cheyenne Plains Compressor Station Operating Permit No. 05OPWE281 Technical Review Document—Renewal Operating Permit On January 30, 2013, EPA published changes to Subpart ZZZZ in the Federal Register as a final rule to include a limit on the number of hours that this type of emergency engine may operate in certain scenarios in order to qualify as an engine subject to limited requirements. Prior to this date, the rule had no time limit on the use of emergency engines for routine testing and maintenance. The Division modified the existing permit requirement to track hours of operation so that it also tracks the type of operation in order to qualify as an emergency engine under Subpart ZZZZ. The D.C. Circuit Court issued a mandate on May 4, 2016 for vacatur for certain requirements allowing emergency engines to operate for limited hours for demand response. Upon issuance of the mandate, 40 CFR Part 63.6640(f)(2)(ii)-(iii) have no legal effect. Operation of emergency engines is limited to emergency situations specified in 63.6640(f)(1); maintenance checks and readiness testing for a limited number of hours per year as specified in 63.6640(f)(2)(i); and certain non-emergency situations as specified in 63.6640(0(3). See EPA memorandum dated April 15, 2016 regarding "Guidance on Vacatur of RICE NESHAP and NSPS Provisions for Emergency Engines" for more information. Note that the Subpart ZZZZ requirements for this unit are not currently state enforceable, since the version of Subpart ZZZZ that is currently adopted into Colorado Reg No. 8 states that new emergency engines are not subject to any requirements except for the submittal of an initial notification. 40 CFR Part 60 Subpart JJJJ—Standards of Performance for Stationary Spark Ignition Internal Combustion Engines Subpart JJJJ applies to stationary spark ignition engines that commenced construction, reconstruction or modification after June 12, 2006 and were manufactured after specific dates. EG-6141 started up in 2004 and has not been reconstructed or modified; Subpart JJJJ does not apply. Colorado Regulation No. 7, Part D, Section IV- (State Only) Control of Emissions from the Natural Gas Transmission and Storage Segment The requirements of Section IV apply to transmission segment owners or operators, and are generally applicable on a company-wide basis. Only the facility-specific requirements of this section are included in the permit. Colorado Regulation No. 7, Part E, Section I - Control of Emissions from Engines On December 12, 2008, the Colorado Air Quality Control Commission (AQCC) adopted revisions to Colorado Regulation No. 7 to include state-wide requirements for existing (constructed or modified before February 1, 2009) internal combustion engines greater than 500 hp. These requirements are set forth in Reg 7, XVII.E.3 (now Part E, Section I.D.3.). Specifically these engines are required to install oxidation catalysts per Section I.D.3.b.(i). However, Section I.D.3.b.(ii) specifies that sources that could demonstrate that the retrofit cost was more than $ 5,000/ton were exempt from the requirements, provided the demonstration was submitted by August 1, 2009. The source requested an exemption from the control requirements from these engines 123/0051 Page 5 of 13 Cheyenne Plains Gas Pipeline Company, LLC—Cheyenne Plains Compressor Station Operating Permit No. 05OPWE281 Technical Review Document—Renewal Operating Permit and the Division granted the exemption in a letter dated December 21, 2009, contingent upon engine operation not exceeding 250 hours per year. 40 CFR Part 63 Subpart DDDDD - National Emission Standards for Hazardous Air Pollutants for Maior Sources: Industrial, Commercial, and Institutional Boilers and Process Heaters The major source boiler MACT defines existing boilers and process heaters as those that have commenced construction or reconstruction on or before June 10, 2010. The two hot oil heaters (point 018 - H-8701 and H-8702) qualify as an existing affected source in the subcategory: units designed to burn gas 1 fuels. Only work practice standards apply to this subcategory: annual tune ups and an initial energy assessment. The two reboiler burners (point 025 - H-8721) associated with the glycol dehydrator are also considered to be process heaters under the definition of Subpart DDDDD. However, the reboiler burners qualify for exemption from Subpart DDDDD under §63.7491(h): Any boiler or process heater that is part of the affected source subject to another subpart of this part. The reboiler burners are part of the glycol dehydrator, which is an affected source under 40 CFR Subpart HHH. 40 CFR Part 60 Subpart GG—Standards of Performance for Stationary Gas Turbines Each of the three turbines (points 015 & 024) included in this permit are subject to Subpart GG (stationary gas turbines with greater than 10 MMBtu/hr that commenced construction, modification or reconstruction after October 3, 1977 and before February 8, 2005). The applicable requirements were included in the initial operating permit (note that some of the Subpart GG requirements were streamlined out in favor of more stringent requirements; see the TRD for the initial operating permit issuance for details). 40 CFR Part 63 Subpart HH—National Emission Standards for Hazardous Air Pollutants From Oil and Natural Gas Production Facilities Subpart HH applies to facilities that process, upgrade, or store natural gas prior to the point at which natural gas enters the natural gas transmission and storage source category. This source is in the transmission and storage source category, and is therefore subject to Subpart HHH instead of HH. 40 CFR Part 63 Subpart HHH—National Emission Standards for Hazardous Air Pollutants From Natural Gas Transmission and Storage Facilities The dehydrator is subject to control requirements under Subpart HHH, as described in the TRD for the initial operating permit issuance and the requirements were updated accordingly to revisions to Subpart HHH in the Federal Register on August 16, 2012 as a final rule, for the first operating permit renewal. There has been no update to this subpart since that issuance. The source complies with the option to control to 0.90 Mg/year of benzene (§63.1275(b)(1)(ii)) by routing emissions through a closed vent system to a flare. See previous version of the TRD for more Subpart HHH discussions. 123/0051 Page 6 of 13 Cheyenne Plains Gas Pipeline Company, LLC—Cheyenne Plains Compressor Station Operating Permit No. 05OPWE281 Technical Review Document—Renewal Operating Permit Colorado Regulation No. 7, Part D, Section II.D (State Only) Emission reductions from glycol natural gas dehydrators Colorado Regulation No. 7, Part D, Section II.D includes state-wide requirements for glycol dehydrators with actual uncontrolled VOC emissions greater than 15 tons per year. However, these requirements do not apply to glycol dehydrators located at natural gas storage facilities. Therefore, Section II.D requirements do not apply to the dehydrator at Cheyenne Plains Compressor Station. Subpart LLL—Standards of Performance for SO2 Emissions From Onshore Natural Gas Processing for Which Construction, Reconstruction, or Modification Commenced After January 20, 1984, and on or Before August 23, 2011 The amine unit was previously determined to be an affected unit under this rule, but was exempt from control requirements based on the facility's design capacity. However, the Subpart LLL applies only to onshore natural gas processing plants. Since this facility is not a gas processing plant, the requirement to maintain records demonstrating the exemption under Subpart LLL will be removed from the renewal permit. In previous permitting actions when Subpart LLL was determined to apply, there was no information within Subpart LLL that provided clarification on whether "Onshore Natural Gas Processing" included natural gas processes located at facilities other than natural gas processing plants. When NSPS Subpart OOOO was proposed on August 23, 2011, the preamble for that rule clarified that Subpart LLL was only applicable to natural gas processing plants (reference 76 FR 52741 & 52754). 40 CFR Part 60 Subpart OOOO - Standards of Performance for Crude Oil and Natural Gas Production, Transmission and Distribution Subpart OOOO addresses gas wells, compressors, pneumatic controllers, storage vessels, equipment leaks associated with process units, and some sweetening units. Subpart OOOO applies to affected facilities that commenced construction, modification or reconstruction after August 23, 2011. All equipment at Cheyenne Plains Compressor Station was constructed prior to this applicability date and has not since been reconstructed or modified. Additionally, the following equipment does not qualify as an affected facility under Subpart OOOO, regardless of construction/modification/relocation date for the following reasons: • Compressors are only affected facilities if they are located between the wellhead and the natural gas transmission and storage segment. Since this facility is a natural gas storage facility, all compressors do not qualify as affected facilities. • Pneumatic controllers > 6 scfs are only affected facilities if they are located between the wellhead and the natural gas transmission and storage segment. Other pneumatic controllers are only affected facilities if they are located at a 123/0051 Page 7 of 13 Cheyenne Plains Gas Pipeline Company, LLC—Cheyenne Plains Compressor Station Operating Permit No. 05OPWE281 Technical Review Document—Renewal Operating Permit natural gas processing plant. Since this facility is a natural gas storage facility, all pneumatic controllers do not qualify as affected facilities. • Sweetening units (e.g., amine units) are only affected facilities if they are located at natural gas processing plants. Since this facility is not a natural gas processing plant, the amine unit is not an affected facility. • Equipment leaks associated with process units (i.e., fugitive components) are only affected facilities if they are located at natural gas processing plants. Since this facility is not a natural gas processing plant, the amine unit is not an affected facility. • Note that there are no storage vessels associated with this permit, either as permitted emission units or as insignificant activities. 40 CFR Part 60 Subpart KKK- Standards of Performance for Equipment Leaks of VOC From Onshore Natural Gas Processing Plants Subpart KKK does not apply to the Cheyenne Plains Compressor Station because it is not a natural gas processing plant. 40 CFR Part 60 Subpart Kb - Standards of Performance for Volatile Organic Liquid Storage Vessels (Including Petroleum Liquid Storage Vessels) for Which Construction, Reconstruction, or Modification Commenced After July 23, 1984 As per§ 60.110b(d)(4), Subpart Kb does not apply to vessels with a design capacity less than or equal to 1,589.874 m3 (approximately 10,000 bbl) used for petroleum or condensate stored, processed, or treated prior to custody transfer. There are no such tanks associated with this permit. 40 CFR Part 63 Subpart EEEE — National Emission Standards for Hazardous Air Pollutants: Organic Liquids Distribution (Non-Gasoline) Under §63.2334(c)(2), organic liquid distribution operations do not include activities and equipment at natural gas transmission and storage facilities; therefore, Subpart EEEE requirements do not apply. Portable Monitoring Requirements The previously issued version of the operating permit required quarterly portable monitoring for NOx and CO emissions from the turbines. The requirement used the Division's standard portable monitoring language, except that the following additional language was included: Note that the second to the last paragraph in Condition 5 (apply for a permit modification within 60 days if the portable analyzer test indicates that the emission rates/factors are greater than the emission rates/factors identified in the permit) does not apply to these emission units. This requirement was included because these turbines are subject to BACT limits for NOx and CO, and the emission factors specified in the permit are associated with the 123/0051 Page 8 of 13 Cheyenne Plains Gas Pipeline Company, LLC—Cheyenne Plains Compressor Station Operating Permit No. 05OPWE281 Technical Review Document—Renewal Operating Permit original BACT determination. This additional language will also be included in the renewal permit. Compliance Order There has been no compliance order against CIG for violating requirements under Operating Permit 05OPWE281. IV. Modifications Requested by the Source The renewal application received on March 30, 2018 requested the following modifications: • Update to the secondary responsible official. • Update to the permit contact person. • Changes to Summary of Emissions Units: o Engine serial number of CG-7101 to be changed from OCH10-B8166 to OHC10-B8166. o Engine serial number of CG-7301 to be changed from OCH10-B0020 to O H B 16-B8446. • Addition of the following to the List of Insignificant Activities: o Waste Tank T-8807. o Waste Tank T-8811. Cheyenne Plains Gas Pipeline Company, LLC provided comments to the draft permit on July 13, 2020, and requested the requirement to use the hours meter on the pilot monitor and record the number of hours the turbine runs when ambient temperatures are below 0 ° F to be reassessed, since the current version of Solar's SoLoNOx operating system does not turn the pilot on and off like the original SoLoNOx did. The source's requested modifications were addressed as follows: Page Following Cover Page • Added Ron Bessette, VP Operations as secondary responsible official. • Updated Matt Richards as the permit contact person (originally Justin Rivard in the renewal application, but the contact has since changed). Section I — General Activities and Summary • Condition 7 - Summary of Emissions Units Table: updated serial numbers for point 015 (CG-7101) & 024 (CG-7301). Section II — Specific Permit Terms 123/0051 Page 9 of 13 Cheyenne Plains Gas Pipeline Company, LLC—Cheyenne Plains Compressor Station Operating Permit No. 05OPWE281 Technical Review Document—Renewal Operating Permit • Condition 1.2.1.4: removed language requiring the hours meter on the pilot to be used to monitor and record the number of hours the turbine runs when ambient temperatures are below 0 ° F. Added language to require the source to manually monitor and record the number of hours the turbine runs when ambient temperatures are below 0 ° F, and record keeping requirement. Appendices • Appendix A - List of Insignificant Activities: added Waste Tank T-8807 & Waste Tank T-8811 to the list. V. Other Modifications In addition to the source requested modifications, the Division has included changes to make the permit more consistent with recently issued permits, include comments made by EPA on other Operating Permits, as well as correct errors or omissions identified during inspections and/or discrepancies identified during review of this renewal. These changes are as follows: Page Following Cover Page • It should be noted that the monitoring and compliance periods and report and certification due dates are shown as examples. The appropriate monitoring and compliance periods and report and certification due dates will be filled in after permit issuance and will be based on permit issuance date. Note that the source may request to keep the same monitoring and compliance periods and report and certification due dates as were provided in the original permit. However, it should be noted that with this option, depending on the permit issuance date, the first monitoring period and compliance period may be short (i.e. less than 6 months and less than 1 year). Section I — General Activities and Summary • Revised the language in Condition 1.4 to include current conditions that are state-only enforceable (adding Section IV, Condition 30). • Condition 2.2.5: revised outdated references Reg 3, Part D, Sections II.A.42 to the current II.A.44. • Condition 4: revised outdated references Reg 3, Part D, Sections II.A.26 and 42 to the current II.A.27 and 44.

Currently we don't have a "clock" on the pilot. This version of Solar's Solonox operating system does not turn the pilot on and off like the original Solonox did. We manually track both <0 and <20 hrs (and have mechanical meters for<0 hours). With this is mind will our current recordkeeping be acceptable or would it be best to change the language in the draft to just general hour tracking rather than with a clock? https://mail.google.com/mail/u/1?ik=0c94807f4c&view=pt&search=all&permthid=thread-a%3Ar-8488480080157367949&si mpl=msg-a%3Ar-84868275... 1/3 7/20/2020 State.co.us Executive Branch Mail-Cheyenne Plains Compressor Station OP Renewal Draft Source Comments Request Appreciate your help!
