Proposed Carbon Monoxide (CO)Emissions Testing of Diesel-Fired Peak Shaving
Generator ES-14 by Integrity Air Monitoring, Inc. October 20,2020
Dear Mr. Aust:
The North Carolina Division of Air Quality(DAQ)has reviewed the protocol submittal form(PSF)for CO
emissions testing of generator ES-I4. Integrity Air Monitoring proposes EPA Method 3A for oxygen(02)and
EPA Method 10 for CO emissions testing. The proposed emissions testing is acceptable for demonstrating
compliance with the applicable regulations.
ES-14 is a diesel-fired peak shaving generator controlled by diesel oxidation catalyst CD-14. The generator is
rated at 764 horsepower maximum capacity. 40 CFR 63 Subpart ZZZZ National Emissions Standards for
Hazardous Air Pollutants for Stationary Reciprocating Internal Combustion Engines applies and specifies CO
emissions shall be reduced by 70%or more using an oxidation catalyst. Permit condition 2.1.C.3 states the
temperature of the catalyst inlet should be maintained at>450°F and< 1350'F. The pressure drop across the
catalyst should be maintained f 2 inches of water at 100%load f 10%from the pressure drop that was
measured during the most recent performance test. Integrity proposes testing at the inlet and outlet of the
catalyst with the differential pressure across the catalyst,temperatures,and engine output being recorded every
15 minutes. The CO and 02 measurements should be dry and the engine should be tested at±10%of
maximum load.
The proposed emissions testing is acceptable. Approval of the protocol does not exempt the tester from the
minimum requirements of the methods. Deviation from the methods remains subject to approval by DAQ. If
there are any questions regarding this review,please contact me at(919) 707-8427 or Brent.Hallkncdenr.gov.
Sincerely,
Brent W. Hall
