Therefore, the Air Pollution Control Division of the Colorado Department of Public Health and Environment hereby gives NOTICE, pursuant to Section 25-7-114.5(5), C.R.S. of the Colorado Air Quality Control Act that an application to the Division has been received for an emission permit on the following proposed project and activity: DCP Midstream, LP has submitted an application to construct and operate one (1) additional natural gas fired reciprocating internal combustion engine at their Roggen Natural Gas Processing Plant. The engine will be used for residue gas compression. The engine is equipped with non-selective catalytic reduction and is permitted to operate at full load for 8,760 hours per year. With the controls on this engine, emissions from this engine will be below the significance level. This facility is located at 35409 Weld County Road 18 near Roggen, Colorado, which is located in Weld County. The existing facility is a major stationary source for purposes of non-attainment area new source review (NANSR) requirements. With the emission limits on the proposed new engine, this project is considered a synthetic minor modification to an existing major stationary source for purposes of NANSR(with respect to NOR, which is a precursor for ozone). The Division has determined that the engine will comply with all applicable standards and regulations. The Division therefore proposes to issue the applicant an initial approval permit for the one(1)proposed new engine. The Division hereby solicits and requests submission of public comment concerning the aforesaid proposed project and activity for a period of thirty(30)days from and after the date of this publication. Comments are solicited on the ability of the proposed project to comply with applicable standards and regulations. Any such comment must be in writing and be submitted to the following addressee: Geoffrey Drissel Colorado Department of Public Health and Environment APCD-SS-B 1 4300 Cherry Creek Drive South Denver, Colorado 80246-1530 Within thirty (30)days following the said thirty(30)-day period for public comment,the Division shall consider comments and, pursuant to Section 25-7-114.5(7)(a), either grant,deny,or grant with conditions,the emission permit. Said public comment is solicited to enable consideration of approval of and objections to the proposed construction of the subject project and activity by affected persons.

Alternative Operating Scenarios The following Alternative Operating Scenario(AOS)Ix temporary and permanent engine replacement has been reviewed in accordance with the requirements of Regulation No. 3., Part A, Section IV.A,Operational Flexibility Alternative Operating Scenarios,and Regulation No. 3,Part B,Construction Permits, and Regulation No. 3,Part D, Major Stationary Source New Source Review and Prevention of Significant Deterioration,and has been found to meet all applicable substantive and procedural requirements. This permit incorporates and shall be considered a Construction Permit for any engine replacement performed in accordance with this AOS,and the permittee shall be allowed to perform such engine replacement without applying for a revision to this permit or obtaining a new Construction Permit. 1.1 Engine Replacement The following AOS is incorporated into this permit in order to deal with an engine breakdown or periodic routine maintenance and repair of an existing onsite engine that requires the use of either a temporary or permanent replacement engine. "Temporary" is defined as in the same service for 90 operating days or less in any l2 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 counts towards the 90-day total. Note that the compliance demonstrations and any periodic monitoring required by this AOS are in addition to any compliance demonstrations or periodic montoring 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). Results of all tests and the associated calculations pursuant required by this AOS shall be submitted to the Division within 30 calendar days of the test. 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 to contemporaneously record the start and stop date of any engine replacement,the manufacturer,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 seral number of the replacement engine. 1.1.1. The permittee may temporarily replace an existing engine that is subject to the emission limits set forth in this permit with an engine that is of the same manufacturer, model,and horsepower or a different manifacturer, model,or horsepower as the existing engine without modifying this permit so long as the emissions from the temporary replacement engine comply with the emission limitations for the existing permitted engine as determined in section 1.2. Measurement of emissions from the temporary replacement engine shall be made as set forth in section 1.2. 1.1.2. The permittee may permanently replace the existing compressor engine that is subject to the emission limits set forth in this permit with an enginethat is of the same manufacturer,model and horsepower without modifying this permit so long as the emissions from the permanent replacement engine comply with the emission limitations for the existing permitted engine as determined in section 1.2. Measurement of emissions from the permanent replacement engine shall be made as set forth in section 1.2. An Air Pollutant Emissions Notice(APEN)that includes the specific manufacturer,model and serial number and horsepower of the permanent replacement enghe shall be filed with the Division for the permanent replacement engine within 14 calendar days of commencing operation of the replacement engine. The APEN shall be accompanied by the appropriate APEN filing fee and a cover letter explaining that the peanittee is exercising an alternative operating scenario and is installing a permanent replacement engine. This AOS cannot be used for permanent engine replacement of a grandfathered or permit exempt engine or an engine that is not subject to emission limits. AIRS ID: 123/0049/134 Page 8 of 1 l • -DCP Midstream,LP Colorado Department of Pubh tent Permit No.07WE0988 Air DRAFT ion Initial Approval PERMIT _ The permittee shall agree to pay fees based on the normal permit processing rate for review of information submitted to the Division in regard to any permanent engine replacement. If Subpart ZZZZ is newly triggered by a permanent replacement engine,the permittee must apply for a revision to their operating permit within 90 days of installation. 1.2 Portable Analyzer Testing The permittee shall measure nitrogen oxides(NOr)and carbon monoxide(CO)emissions in the exhaust from the replacement engine using a portable flue gas analyzerwithin seven(7) calendar days of commencing operation of the replacement engine. All portable analyzer testing required by this permit shall be conducted using the Division's Portable Analyzer Monitoring Protocol(ver March 2006 or newer)as found on the Division's website at: http://www.cdphe.state.co.us/ap/down/portanalyzeproto.pdf Results of the portable analyzer tests shall be used to monitor the compliance status of this unit. 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 NQ<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 NQ(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 indicatcs compliance with both the NOx and CO emission limitations or until the engine is taken offline. 1.3 Additional Sources The replacement of an existing engine with a new engine is viewed by the Division as the installation of a new emissions unit,not"routine replacement" of an existing unit. The AOS is therefore essentially an advanced construction permit review. The AOS cannot be used for additional new emission points for any site; an engine that is being installed as an entirely new emission poirt and not as part of an AOS-approved replacement of an existing onsite engine has to go through the appropriate Construction permitting process prior to installation.

The General O&M Plan shall become the default O&M Plan for natural gas-fired RICE unless the source chooses to submit a specific O&M Plan to the Division for review and approval through the Final Approval permitting process. The source shall maintain records to demonstrate compliance with either the General O&M Plan or another O&M Plan approved by the Divsion. The source shall provide documentation and recordkeeping to demonstrate compliance with the O&M Plan upon request by the Division. All engines shall comply with the following operating parameters and maintenance schedules: 1. The source shall follow the manufacturer's scheduled maintenance guide for the engine and document the date that activities were completed. If a company has established its own maintenance schedule then this schedule may be followed presuming it is consistent with good air polluion control practices for minimizing emissions as defined in the New Source Performance Standard(NSPS)general conditions. Determination of whether or not acceptable operating and maintenance procedures are being used will be based on information available to the Division,which may include,but is not limited to,monitoring results, opacity observations,review of operating and maintenance procedures, and inspection of the source. (Reference:Regulation No. 6, Part A. General Provisions from 40 CFR 60.11) Parameters 2 and 3 apply only to rich burn engines equipped with an air-fuel ratio controller. 2. The source shall maintain records to verify that the air-fuel ratio controller(AFRC) is operated per the manufacturer's recommendations. The oxygen sensa.millivolt(mV)reading of the AFRC shall be recorded per the schedule in Table 1. Additionally,the mV reading shall be tracked and recorded during each portable analyzer test. 3. The source shall follow the manufacturer's oxygen sensor replacement schedde if an oxygen sensor is utilized. If the equipment maintenance and replacement is dependent on the hours of operation then the hours shall be tracked and recorded and made available to the Division upon request. If the source is using a method other than hours of operation to track oxygen sensor replacement then tracking must be recorded and available to the Division upon request. Records of oxygen sensor replacement shall be made available to the Division upon request. 4. The source shall clean,recondition and replace the catalyst per the manufacturer's or packager's recommended schedule. A copy of this maintenance schedule shall be made available to the Division upon request. If maintenance activities or actions are dependent upon hours of operatim then engine operating hours shall be recorded and made available to the Division upon request. Records of the catalyst cleaning, reconditioning or replacement shall be documented and made available to the Division upon request. 5. The source shall record the inlet temperature into the catalyst per the schedule specified in Table 1.

If the temperature is outside this range then the appropriate maintenance activities shall be performed. 6. The source shall monitor and record the pressure drop across the catalyst monthly. The pressure differential shall not deviate by more than 2 inches of water column from the baseline value established by the source when the engine is operating at 90%- 110%load. Baseline pressure differential shall be established by the source and recorded during each portable analyzer test. If the pressure differential exceeds baseline values by more 2 inches water column then the appropriate maintenance shall be performed. Note: If the pressure differential is not within the parameters established during a baseline performance test, then the source may forgo maintenance activities and perform a portable analyzer test of the engine to establish new pressure differential baseline. The most recent baseline pressure differential established during portable analyzer testing shall be used to determine compliance. 7. Compliance demonstration: a. Existing Permitted Engines: i. Pressure differential across the control equipment shall be established within the first 100 hours of engine operations from the date that the catalyst is cleaned,reconditioned,or replaced. b. Newly Permitted Engines or Engines Associated with a Permit Modification: i. Pressure differential across the control equipment shall be established within 180 days from the date of equipment startup for newly permitted engines or within 180 days from the date of permit issuance for engines associated with a modified permit. 8.
