MEMORANDUM
To: Steven Vozzo, Supervisor,Fayetteville Regional Office
From: James E. Hammond, Stationary Source Compliance Branch(SSCB)
Subject: Piedmont Natural Gas(PNG),Wadesboro Compressor Station,Anson County,North Carolina
Facility ID 0400056; Permit No. 10097T01
Emissions Testing of Compressor Engines ID COMPOI, COMP02, COMP03,COMP04
Performed August 17, 2016 by Air-Tech Environmental Corporation (Air-Tech)
DAQ Tracking No.2016-182st
Air-Tech performed testing on COMPO1, COMP02, COMP03, and COMP04 compressor engines.
Emission sources COMPOI through COMP04 are four natural gas-fired, four-stroke lean burn(4FSLB)
internal combustion reciprocating engines(4,735 horsepower rating)equipped with oxidation catalyst for
carbon monoxide control on each engine. Each engine powers a natural gas compressor. The test report
has been reviewed and is deemed acceptable.
EPA Reference Methods performed were: 10 for carbon monoxide(CO), 25A for total volatile organic
compounds(VOC), 18 for methane(CH4), and 7E for nitrogen oxides(NO,,)emissions.
COMPO1, COMP02, COMP03, and COMP04 are subject to:
• 40 CFR 60 Subpart JJJJ Standards of Performance for Stationary Spark Ignition Internal
Combustion Engines
0 40 CFR 63 Subpart ZZZZ National Emission Standards for Hazardous Air Pollutants for
Reciprocating Internal Combustion Engines(RICE MACT)
• 15A NCAC 2D .1423 Large Internal Combustion Engines(RACT)
63 Subpart ZZZZ states that a facility subject to both 60 Subpart JJJJ and 63 Subpart ZZZZ meets the
requirements of 63 Subpart ZZZZ by meeting the requirements of 60 Subpart JJJJ.
SSCB has reviewed the testing..Results are acceptable to demonstrate compliance with the applicable
standards. The test results, limits, and operating parameters are tabulated on the following page.
The test results are acceptable and demonstrate compliance of COMPOI through COMP04 for applicable
NO, CO and VOC emissions requirements. If there are any questions concerning this review,please
contact me at(919) 707-8412 [e-mail].
