COMP02, COMP03, and COMP04 Air Quality Permit No. 10097T02 Piedmont Natural Gas - Wadesboro Compressor Station Wadesboro,North Carolina,Anson County Facility ID: 0400056 Fee Class: Title V Dear Mr. Long: The Division has reviewed your source test results report that was received by our Central Office on 15 August 2022. The report was for source testing on four-stroke lean-burn natural gas-fired reciprocating internal combustion engines (ID Nos. COMP02, COMP03, and COMP04), conducted on 21-22 June 2022. The testing was conducted pursuant to 40 CFR Part 63 Subpart ZZZZ National Emissions Standards for Hazardous Air Pollutants for Stationary Reciprocating Internal Combustion Engines and 40 CFR Part 60 Subpart JJJJ Standards of Performance for Stationary Spark Ignition Internal Combustion Engines for the purpose of demonstrating compliance with emission standards for nitrogen oxides (NOx), carbon monoxide (CO), and volatile organic compounds (VOC). On 21 September 2022, this Division determined that the subject testing performed at your facility was an acceptable source test. The review determined that compliance with the applicable emission standards is indicated for these sources. A copy of the determination memorandum, issued by Ms. Taylor Fort, of the NC Division of Air Quality, Stationary Source Compliance Branch, is attached. Should you have any questions regarding this matter,please contact Mr. Stephen Allen, Environmental Specialist, at (910) 433-3300, in the Fayetteville Regional Office. Sincerely, Heather S.

The tested sources are three of four(4) four-stroke lean-burn natural gas-fired reciprocating internal combustion engines COMPOI through COMP04, each powering a compressor and rated 4,735 horsepower. The engines are controlled by respective catalytic oxidizers COMPO 1 C through COMP04C. The revised testing waiver issued on February 14, 2022 exempts COMPO 1 from this round of testing. The emissions test results demonstrate compliance with the applicable regulations. 40 CFR 63 Subpart ZZZZ National Emissions Standards for Hazardous Air Pollutants for Stationary Reciprocating Internal Combustion Engines, 40 CFR 60 Subpart JJJJ Standards of Performance for Stationary Spark Ignition Internal Combustion Engines, and 15A NCAC 2D .1423 Large Internal Combustion Engines apply. Compliance with 63 Subpart ZZZZ is met by complying with the limits of 60 Subpart JJJJ. Compliance may be indicated in units of either grams per horsepower-hour(g/HP-hr) or parts per million corrected to 15%oxygen (ppmvd@ 15%0?). The emissions test results are shown in the following tables. 2022-089ST: COMP02 Emissions Test Results June 21,2022 Pollutant Test Result Emission Limit Standard Compliance 0 82 ppmvd@ 15%O� 60 Subpart JJJJ NOx 37.4 ppmvd@ 15/oOz 125 ppmvd@ 15%0? 2D .1423 Yes CO 6.2 ppmvd@ 15%0, 270 ppmvd@ 15%02 60 Subpart JJJJ VOC as methane 2.3 ppmvd@15%O-) 60 ppmvd@ 15%02 60 Subpart JJJJ 2022-224ST: COMP03 Emissions Test Results June 22,2022 Pollutant Test Result Emission Limit Standard Compliance 0 82 ppmvd@15%02 60 Subpart JJJJ NOx 38.0 ppmvd@ 15/0O? 125 ppmvd@ 15%0? 2D .1423 Yes CO 5.3 ppmvd@15%0� 270 ppmvd@15%Oz 60 Subpart JJJJ VOC as methane 2.5 ppmvd@15%O? 60 ppmvd@15%O, 60 Subpart JJJJ September 21, 2022 Piedmont Natural Gas—Wadesboro Compressor Station Tracking Nos. 2022-089ST, 2022-224ST, 2022-225ST Page 2 2022-225ST: COMP04 Emissions Test Results June 22,2022 Pollutant Test Result Emission Limit Standard Compliance NOx 37.6 ppmvd@15%O2 82 ppmvd@15%02 60 Subpart JJJJ 125 ppmvd@ 15%OZ 2D .1423 Yes CO 4.1 ppmvd@ 15%OZ 270 ppmvd@ 15%02 60 Subpart JJJJ VOC as methane 1.6 ppmvd@ 15%02 60 ppmvd@ 15%02 60 Subpart JJJJ Testing was conducted within 10 percent of the highest achievable load during normal operations.The test rates are acceptable.
