Emissions Testing of Engine COMPOI
By Mostardi Platt on August 6,2019
DAQ Tracking No. 2019-166ST
Mostardi Platt performed EPA Method 320 for determining emissions of nitrogen oxides(NOx), carbon
monoxide(CO), and volatile organic compounds(VOC) from engine COMPOL PNG requested a waiver
to test one engine as being representative of engines COMPOI through COMP04. North Carolina
Division of Air Quality(DAQ) granted the waiver(7/29/2019) and PNG tested engine COMPOI I. The
primary purpose of the testing is to satisfy 60 Subpart JJJJ requirements for periodic testing once every
three years or every 8760 hours,whichever occurs first. The emission test results demonstrate
compliance with the applicable regulations.
COMPOI is a natural gas-fired,four-stroke lean-burn internal combustion reciprocating engine [rated at
4735 horsepower(hp)] controlled by a catalytic oxidizer. 40 CFR 63 Subpart ZZZZ National Emissions
Standards for Hazardous Air Pollutants for Stationary Reciprocating Internal Combustion Engines and
40 CFR 60 Subpart JJJJ Standards of Performance for Stationary Spark Ignition Internal Combustion
Engines apply. Compliance with 63 Subpart ZZZZ is met by complying with the limits of 60 Subpart
JJJJ. The emissions test results are shown in the table below.
Pollutant Test Result' Emission Limit Reizulation Com liance
NO, 39.6 ppmvd@ 15%02 82 mvd 15%02
CO 1.9 mvd 15%02 270 mvd 15%02 60 Subpart JJJJ Yes
VOC as propane 2.2 mvd 15%O2 60 mvd 15%02
ppmvd@15%02=parts per million volume dry at 15%oxygen
COMPOl averaged 4531 horsepower during testing of 95.7%. This operating rate is acceptable. The
emissions test results demonstrate compliance with the applicable regulations. If there are any questions
regarding this review,please contact me at(919)707-8427 or Brent.Hallna ncdenr.aov.
