Proposed Carbon Monoxide(CO)Emissions Testing of Diesel-Fired Peak Shaving
Generator ES-I4 by Integrity Air Monitoring,Inc. October 25,2018
DAQ Tracking No. 2018-275ST
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 methods are acceptable for
demonstrating compliance with the applicable regulations.
ES-I4 is a diesel-fired peak shaving generator controlled by diesel oxidation catalyst CD-I4. 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 OF and< 1350 OF. The pressure drop across the catalyst should be maintained f 2 inches of water
from the pressure drop that was measured during the most recent performance test with the engine
operating at±10%of full load.
Integrity proposes testing at the inlet and outlet of the catalyst with the differential pressure across the
catalyst and temperatures being measured every minute and engine output being measured and recorded
every 5 minutes. The CO and 02 measurements should be dry and the engine should be tested at±10%of
maximum load.

The proposed testing is acceptable for demonstrating compliance with the regulations. 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 [e-mail].
