Hammond, Stationary Source Compliance Branch(SSCB) i1 Subject: Piedmont Natural Gas(PNG),Wadesboro Compressor Station,Anson County,North Carolina Facility ID'0400056;Permit No. 10097ROO Initial Emissions Testing of Compressor Engines ID COMPOI, COMP02,COMP03, COMP04 Performed April 25 to 27,2014 by Air-Tech Environmental Corporation(Air-Tech) DAQ Tracking No.2014-007st _ This is a revision to the October 1, 2014 memo issued for DAQ tracking No. 2014-007st. This memo supersedes the October 1,2014 memo. Air-Tech performed initial testing on COMPOI, COMP02, COMP03,and COM204 compressor engines. Emission sources COMP01 through COW04 are four natural gas-fired,four-stroke lean bum(4FSLB) internal combustion reciprocating engines(4,735 horsepower rating)equipped with oxidation catalyst CO control on each engine. Each engine powers a natural gas compressor. The test report has been reviewed and is deemed acceptable. EPA reference methods(RM)performed were:RM10 for carbon monoxide(CO),RM25A for total volatile organic compounds(VOC),RM18 for methane(CH,), and Method RM7E nitrogen oxides(NO ) emissions for COMPOI, COMP02, COMP03, and COMP04. COMPOI, COMP02,COMP03,and COMP04 are subject to: s 40 CFR 60 Subpart JJJJ Standards of Performance for Stationary Spark ignition Internal ,Combustion Engines e 40CFR 63-Subpart ZZZZ NationalEmission Standardsfor Hazardous Air Pollutants for ,Reciprocating Internal Combustion Engines(RICE MALT) e 15A NCAC 2D .1423 Large Internal Combustion Engines(PACT).. 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. The results are acceptable to establish CO and VOC emission factors for PSD/NSR avoidance assessments as required by permit section 2.2 A.3.b. Results are also 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 COMP01 through COMP04 for applicable NOx, CO and VOC emissions requirements.
