Protocol for Carbon Monoxide Emissions Testing of MACT Subpart ZZZZ
Diesel-Fired Non-emergency/Peak Shaving Generator(ID No. ES-I4)
Proposed Test Date October 11,2022,To Be Performed by Integrity Air Monitoring, Inc.
Tracking No. 2022-220ST
Dear Mr. Cullipher:
The emission source to be tested is an existing Caterpillar diesel-fired(764 horsepower,—576 kW),
shaving generator ID No. ES-I4,>500 hp,with emissions controlled by diesel oxidation catalyst CD-I4.
40 CFR 63 Subpart ZZZZ National Emissions Standards for Hazardous Air Pollutants for Stationary
Reciprocating Internal Combustion Engines applies. 40 CFR 63 Subpart ZZZZ limits CO exhaust
emissions to no more than 23 ppmvd at 15%oxygen or a minimum 70%catalyst CO reduction efficiency.
In addition to 40 CFR 63 Subpart ZZZZ permit condition 2.1.B.3 j also applies and requires
CO emissions to be reduced by 70%or more using an oxidation catalyst.
The proposed methods are EPA Methods 1, 3A, and 10 at both oxidation catalyst inlet and outlet
locations. The testing shall consist of three 60-minute test runs. A stratification test as described in
Section 8.1.2 of EPA Method 7E must also be performed to determine the CO sampling points.
The operating rate during testing must be within f 10%of full load or within f 10%of maximum normal
load if the generator design capacity is considerably larger than the nominal demand capacity. The
generator electrical output must be recorded at the start of each test run and at least once every 15 minutes
during each run. The following operating data must also be collected: oxidation catalyst differential
pressure (DP)and oxidizer inlet temperature. This data will re-establish benchmark monitoring values for
the catalyst. The catalyst pressure drop should not change by more than 2 inches of water from the
benchmark. The generation data and the operation rate data must be included in the report. When
reporting,this data should be averaged both run by run and for the 3 run test set.

Page 2 (Regulator Marine, Inc. —CO Emission Testing for Diesel-Fired Generator ES-I4)
The proposed testing is acceptable to determine the CO emissions reduction efficiency/concentration from
the generator. Approval of this sampling protocol does not exempt the tester from the minimum
requirements of the testing methods. Any deviations remain subject to approval by DAQ.
Note,permit condition 2.LB.3.j requires subsequent performance testing semiannually.
