RELEASED TO: The Greeley Tribune on PUBLISHED: March 19, 2008 March 13, 2008 COLORADO DEPARTMENT OF PUBLIC HEALTH AND ENVIRONMENT AIR POLLUTION CONTROL DIVISION OPERATING PERMIT RENEWAL SUMMARY PERMIT NUMBER: 95OPWE062 AIRS ID#: 1230090 DATE: March 13, 2008 APPLICANT: DC Midstream, LP—Kersey/Mewbourn Gas Processing Plant REVIEW ENGINEER: Lisa Clarke SOURCE DESCRIPTION DCP Midstream has applied for renewal of their Operating Permit issued for the Kersey/Mewbourn Gas Processing Plant located at the junction of Weld County 35 and Weld County Road 38 in Lucerne in Weld County. This facility is located in an area designated as attainment for all criteria pollutants except ozone. This area is classified as non-attainment for ozone and is part of the 8-Hour Ozone Control Area as defined in Regulation No. 7, Section II.A.16. This source is a synthetic minor source with respect to Prevention of Significant Deterioration (PSD). This facility is located within 50 miles of Wyoming, which is an affected state. This facility is located within 100 kilometers of Rocky Mountain National Park, which is a Federal Class I designated areas. This source is subject to the Accidental Release provisions of section 112(r) of the Federal Clean Air Act and the required Risk Management Plan was submitted to the appropriate authority by June 20,1999. Eight(8) engines (C-105, C-106, C-107, C-108, C-109, C-110, C112, C-113, and C-178) are signification emission units equipped with air pollution control devices subject to the Compliance Assurance Monitoring (CAM) requirements in 40 CFR Part 64. The facility is a true minor source of HAPS and is not subject to the requirements of MACT ZZZZ or MACT HHH. The facility is subject to the area source requirements of MACT HH due to the presence of a triethylene glycol dehydrator at this facility, although all emissions from this unit are recycled to the inlet stream.

All of the engines at this facility are controlled with non-selective catalytic reduction systems. Equipment Leaks—The Division added fugitive emissions from equipment leaks of both plants to the Operating Permit. This facility is subject to the requirements of the NSPS KKK. Miscellaneous—The Division modified the hot oil heater to the correct specifications, increased the condensate truck tank loadout throughput, and incorporated four(4) stabilized condensate tanks into the permit. Facility Wide Changes—The language was updated throughout the permit to reflect current Division-Approved language. Language revisions made to: Alternative Operating Scenarios, Portable Monitoring, Ozone Nonattainment Area Requirements, and Appendix B &C. Tech Review Summary—Kersey/Mewbourn Gas Processing Plant Title V Renewal Page 1 TECHNICAL REVIEW DOCUMENT For Renewal of OPERATING PERMIT 95OPWE103 to be issued to: DCP Midstream, LP. Kersey/Mewbourn Gas Processing Plant Weld County Source ID 1230090 Prepared by Lisa Clarke November—December 2007 I. PURPOSE This document will establish 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 proposed for this site. The original Operating Permit was issued June 1, 1999, and expired on June 1, 2004. 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 May 30, 2003; additional information received February 24 and October 20, 2004; August 24, 2005; May 9 and July 12, 2006; June 8 and November 15, 16, 2007; previous inspection reports, and various e-mail correspondence, as well as telephone conversations with the applicant. 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 http://www.cdphe.state.co.us/ap/Titlev.html. 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. In addition to the changes requested by DCP Midstream in the renewal application,the Division has included changes to make the permit consistent with recently issued permits, including comments made by EPA on other Operating Permits,as well as to correct errors or omissions identified during inspections and/or discrepancies identified during review of this renewal. Tech Review Summary—Kersey/Mewboum Gas Processing Plant Title V Renewal Page 3 ' MACT Applicability HHH—Natural Gas Transmission and Storage This facility is a natural gas transmission and storage facility as described in 40 CFR Part 63 Subpart HHH, "National Emission Standards for Hazardous Air Pollutants From Natural Gas Transmission and Storage". However, this facility is a true minor source of Hazardous Air Pollutants (HAPs). Therefore, this facility is not subject to this MACT. HH—Oil and Natural Gas Production Facilities Although this facility is a true minor of HAPs, there are two dehydrators present. However, one of the dehydrators is an ethylene glycol dehydrator (Plant A—point 064) and not subject to the MACT HH. The other dehydrator, a triethylene glycol dehydrator at Plant B (AIRS Point 065) runs through a vapor recovery unit, which is inherent to the process, and only has safety relief devices for venting. The MACT HH defines this system as a"closed-vent system," or a system that is not open to the atmosphere and is composed of piping, ductwork, connections, and if necessary, flow inducing devices that transport gas or vapor from an emission point to one or more control devices. Since the standards for the MACT HH are for the process vents (i.e. the dehydration unit reboiler vent and the vent from the GCG separator (flash tank), if present), this particular unit is not subject to the MACT HH requirements. The facility has been designed as an inherent closed-loop system from start-up. ZZZZ—Stationary Reciprocating Internal Combustion Engines The final rule for RICE was published in the Federal Register on June 15, 2004. Under the rule, for production field facilities, only emissions from glycol dehydrators, storage vessels with the potential for flash emissions, reciprocating internal combustion engines and combustion turbines need to be aggregated to determine if the facility is a major source for HAPS. An analysis was conducted to determine HAP emissions from the equipment at this facility. Total HAP emissions based on permitted production were calculated to be 6.98 TPY, with no single HAP exceeding 5 TPY. This facility is a true minor source of HAPs. Therefore, the RICE MACT does not apply to the Kersey/Mewbourn gas processing plant. 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(100 tons per year). 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: C126, C133, C149, C130, C125, C131, C181 —Waukesha Model L-7042GSI ICE C167—Waukesha Model L-7044GSI ICE The primary purpose of the CAM program is to supplement or enhance the Operating Permit Tech Review Summary—Kersey/Mewboum Gas Processing Plant Title V Renewal Page 5 II.A.42 for which the area is in attainment or attainment/maintenance may result in the application of the PSD review requirements. Emission Sources The following sources are specifically regulated under terms and conditions of the Operating Permit for this plant: Internal Combustion Engines C133, C149, C125, C131 —Waukesha 1,232 HP Engines C126, C130 —Waukesha 1,100 HP Engines C167— Waukesha 1,680 HP Engine C181 —Waukesha 1,478 HP Engine C127, C129, C128 —Waukesha 711 HP Engines C134—Waukesha 750 HP Engine C211 —Caterpillar 300 HP Engine C132—Waukesha 450 HP Engine C243 —Cummins 380 HP Engine C210— Cummins 84 HP Engine Natural Gas Fired 12 MMBtu/Hr Hot Oil Heater(P016) Fugitive Emissions of Volatile Organic Compounds from Equipment Leaks (Plants A & B) (F017) Condensate Tank Truck Loadout Rack (P019) Stabilized Condensate Tanks (P024) 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. Based on the information provided by the applicant, this facility is subject to the provisions of the Accidental Release Prevention Program (Section 112(r) of the Federal Clean Air Act). The Risk Management Plan required by the Act was submitted to the appropriate authority and/or a designated central location by June 20, 1999 and revised accordingly. Emission Factors From time to time published emission factors are changed based on new or improved data. A logical concern is what happens if the use of the new emission factor in a calculation results in a source being out of compliance with a permit limit. For this operating permit, the emission factors or emission factor equations included in the permit are considered to be fixed until changed by the permit. Obviously,factors dependent on the fuel sulfur content or heat content cannot be fixed and will vary with the test results. The formula for determining the emission factors is, however,fixed. It is the responsibility of the permittee to be aware of changes in the factors, and to notify the Tech Review Summary—Kersey/Mewbourn Gas Processing Plant Title V Renewal Page 7 factor. The fuel consumption of each engine at the facility is determined by allocating fuel use to each of the engines based on monthly hours of operation and total engine fuel use. The Division's current (6/1/2006) portable monitoring language has been included in the permit. This requires the source to measure NO„ and CO emissions quarterly. The Btu content of the natural gas fuel shall be measured semi-annually (twice per year) using appropriate methods. DCP is also required to monitor the air fuel ratio controller monthly. • Internal Combustion Engine—Construction Permit 97WE0304/Permit Exempt 07WE1091 DCP applied for the removal of engine 210, the 100 HP Minneapolis Moline, to be replaced with the APEN required permit exempt Cummins G5.9 84 HP engine, on November 16, 2007. Although this engine was permit exempt at the time of submittal, this engine is no longer permit exempt due to the location in the nonattainment ozone area. This new engine will have the same label—C210 —as the previous engine. The AIRS Point is new—the ID is 123/0090/077. 1. Applicable Requirements— • Monthly recordkeeping and calculation of NOx, CO, and VOC • Plant fuel meter tracking of natural gas consumption • Hours of Operation annually • Semi-annual Btu heat content analysis • 20% opacity • Good operation&maintenance • Serial Number Certification 2. Emission Factors—Emissions are determined using manufacturer's specifications for the engine and the catalyst. AP-42 factors were used to determine uncontrolled HAP emissions. The catalyst manufacturer guaranteed 50% destruction of all Hazardous Air Pollutants. The emission factors are detailed in the table below: Pollutant Reported Emission Fuel Based Factor Factor NO„ 2.0 grams/hp-hr 0.54 lbs/MMBtu CO 2.0 grams/hp-hr 0.54 lbs/MMBtu VOC 1.0 grams/hp-hr 0.28 lbs/MMBtu 3. Monitoring Plan—The source must monitor the air fuel ratio (AFR) millivolt reading and the catalytic converter(NSCR) inlet and outlet temperature and pressure measured once per month and recorded. • Internal Combustion Engine—Construction Permit 05WE0631 DCP requested the addition of this engine, a Cummins KTA19GC 380 HP engine equipped with NSCR and an AFR, to the Operating Permit. This Construction Permit was issued on January 31, 2006 and a modification issued on December 3, 2007. This Tech Review Summary—Kersey/Mewboum Gas Processing Plant Title V Renewal Page 9 Permit 97WE0304. Emissions will be emitted from component leaks. A revised APEN was received August 24, 2005 to request a more appropriate VOC limit. 1. Applicable Requirements— • 9.20 TPY VOC emissions. • Compliance with NSPS KKK • The source must submit a NSPS KKK report detailing the specific applicable and non-applicable requirements of NSPS KKK within 6 months of permit issuance. This report will be reviewed and used by the inspector to determine compliance. 2. Emission Factors- Emissions are determined using appropriate emission factors from the EPA document: Protocol for Equipment Leak Emission Estimates, EPA-453/R-95-017). 3. Monitoring Plan—The source must conduct a component count within 90 days of permit issuance. Records of component changes shall be maintained and a physical hard count shall be conducted at least every five years. • Condensate truck loadout—Construction permit 97WE0553 DCP requested that the condensate truck loadout be increased based on actual throughput, with a revised APEN received March 27, 2007, which has been incorporated into the Operating Permit. 1. Applicable Requirements—Compliance limit of 20.45 tons of volatile organic compounds per year and 7.1 million gallons of condensate to be loaded per year. The loadout emissions report only the NonMethane,NonEthane VOC (NMEVOC) as reported in the most recent analysis of the product. The Division requires a copy of the analysis to be kept on-site. 2. Emission Factors—The truck loadout emissions are calculated using the appropriate equation and emission factors from AP-42. 3. Monitoring Plan—The emissions of each pollutant and the gallons of condensate loaded on trucks shall be calculated by the end of the subsequent calendar month. A twelve (12) month rolling total of emissions shall be maintained to verify compliance with the long-term emission limitation. By the end of the new calendar month, a total shall be calculated for the previous 12 calendar months, and compliance determined and recorded. All calculations and compliance determinations shall be made available for Division review upon request. • Stabilized Condensate Tanks—Incorporated into Operating Permit Only Pursuant to Regulation No. 3, Part A, Section II.D.1.eeee, DCP applied for the addition of these four (4) vertical fixed condensate tanks first on December 27, 2002 and then with updated technical information, on October 20, 2004. On July 12, 2006, DCP requested an increase in the emissions from the tanks based on EPA TANKS 4.0. These four tanks have been incorporated into the Operating Permit. 1. Applicable Requirements—Compliance limit of 7.1 tons of volatile organic compounds per year. These tanks would be subject to Regulation No. 7, except that Tech Review Summary—Kersey/Mewboum Gas Processing Plant Title V Renewal Page 11 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). • Added language specifying that the semi-annual reports and compliance certifications are due in the Division's office and that postmarks cannot be used for purposes of determining the timely receipt of such reports/certifications.

Permitted Activities 1.1 The Kersey/Mewbourn Gas Processing plant is classified as a natural gas processing plant as set forth under Standard Industrial Classification 1321. Natural gas is delivered to the plant by pipeline. After condensate is removed from the gas by the inlet scrubbers, the inlet gas is subsequently compressed to processing pressures. The inlet gas is then chilled by the propane refrigerant to remove a natural gas liquid (NGL) product from the stream. The closed loop refrigeration process also acts to stabilize the NGL product. The gas plant consists of two (2) gas processing skids, identified as Plant A and Plant B, to separate ethane, propane, and heavier NGL products from the incoming natural gas stream. All NGL products are transported off-site by pipeline. The site consists of sixteen (16) engines powering natural gas compressors, two (2) natural gas processing skids, one triethylene glycol (TEG) dehydration system, one ethylene glycol (EG) natural gas dehydration, a 12 MMBtu/hr hot oil heater, a condensate truck load-out rack, and four (4) 400 barrel (16,921 gallon) stabilized condensate storage tanks. The TEG skid is designed to dehydrate the inlet gas feeding to Plant B. The Plant B TEG dehydration system operates with a closed loop Vapor Recovery Unit (VRU) that is inherent to the process. The vapors collected in the VRU are recompressed and routed to the inlet gas stream, making this unit a closed-vent system. The EG dehydration system is used to dehydrate the inlet gas feeding to Plant A. The EG unit is under APEN thresholds and considered to be an insignificant activity for the purposes of this permit. Condensate is first collected in a 60,000 gallon pressurized bullet tank. The pressure in the tank is maintained at about 38 PSIG by a vapor recovery unit. Condensate is manually transferred from the bullet tank to each of the 400-barrel stabilized condensate storage tanks. The condensate in the 400-barrel tanks is transported off-site by tanker truck. The Kersey/Mewbourn Gas Processing Plant is located southeast of Gilcrest, Colorado at the intersection of Weld County Roads (WCR) 35 and 38. The area in which the plant operates is classified as attainment for all pollutants except ozone.

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. 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 Operating Permit Number: 95OPWE062 ISSUED: June 1, 1999 LAST REVISED: April 15, 2003 DRAFT RENEWAL Air Pollution Control Division B Colorado Operating Permit Appendix Monitoring and Permit Deviation Report Page B 9 1.5.5 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.
