MEMORANDUM
To: Robert Fisher, Washington Regional Office Supervisor
From: James E. Hammond, Stationary Source Compliance Branch (SSCB)
Subject: Food Lion —Washington - Store#2220 [851 Washington St.]
Washington, Beaufort County, North Carolina
Facility ID 07-00152, Permit Exempt
Carbon Monoxide (CO) Emissions Testing of Diesel Peak Shaving Engine ES-2
CAT 519hp/350kW Diesel-fired Engine/Generator—S/N 1 DZ06756
Performed May 8, 2018 by Environmental Source Samplers, Inc. (ESS)
DAQ Tracking No. 2018-209st
ESS performed EPA Method 3A for oxygen (02) and EPA Method 10 for CO emissions from the
diesel peak shaving engine at the subject Food Lion Store. The emissions test results
demonstrate compliance with the applicable regulations.
40 CFR 63 Subpart ZZZZ National Emissions Standards for Hazardous Air Pollutants for
Stationary Reciprocating Internal Combustion Engines(RICE NESHAP) applies and limits CO
emissions to 23 parts per million volume dry corrected to 15% oxygen (ppmvd@l5%02) OR
requires at least 70% reduction of CO emissions. The facility chose to demonstrate compliance
with the exit concentration. A summary of the emissions test results and operating parameters
is shown in the table below.
Pollutant/Parameter Average Emission Limit Regulation Compliance
CO 6.6 ppmvd@l5%02 23 ppmvd@l5%02 63 Subpart ZZZZ Yes
Power Output 164 kW --- --- ---
Catalyst Inlet Temp. 601-730OF z450°F and <_1350°F 63 Subpart ZZZZ Yes
Catalyst AP 1.1 in. H2O --- --- ---
Note:AP is differential pressure or pressure drop.
63 Subpart ZZZZ states that the engine shall be tested at the maximum rated electrical output
±10%. The pressure drop across the catalyst shall be maintained within ±2 inches of water from
the pressure drop established during the initial performance test. The catalyst inlet temperature
shall be maintained z450°F and <_1350°F. The engine averaged 164 kW, or 47% of maximum
output during testing. This is considered normal operation for this generator and is accepted.
The results are acceptable for this operating range. If the engine is operated at higher loads in
the future, additional testing may be required to establish the catalyst AP and inlet temperature
for the higher operating range.
The emissions test results demonstrate compliance with 40 CFR 63 Subpart ZZZZ regulations.
