MEMORANDUM
To: Robert Fisher,Washington Regional Office
From: Gary L. Saunders, Stationary Source Compliance Branch(SSCB)
Subject: Regulator Marine,Inc.
Edenton,Chowan County,North Carolina
Facility ID 2100073,Permit No. 07132T11
Carbon Monoxide Testing Conducted November 3,2016 on One Diesel-Fired Generator
by Integrity Air Monitoring,Inc.
Tracking No. 2016-279ST
The subject test report has been reviewed.The source tested was one diesel-fired engine/generator used
for emergency and peak-shaving power generation at the facility. The purpose of the testing was to
demonstrate compliance with emission limits established by 40 CFR 63, Subpart ZZZZ(4Z),National
Emission Standards for Hazardous Air Pollutants from Reciprocating Internal Combustion Engines. The
facility must control carbon monoxide(CO)by at least 70%efficiency(inlet and outlet testing). Testing
was conducted simultaneously at the inlet and outlet to demonstrate the reduction efficiency for the unit.
Since this engine is classified as"new"under 4Z,the engine is required to meet a reduction efficiency
standard. The results are summarized below:
Test Result Summary
Test Results
Source Standard Emission Compliance
Inlet Outlet CO
Limit Concentration Concentration Reduction Indicated?
efficient
I-4 40 CFR 70% CO 45.1 ppm 0.216 ppm 99.5% Yes
63 (4Z) reduction
Reduction efficiency results from simultaneous inlet and outlet testing concentrations corrected to 15%Oz
During the test inlet catalyst oxidation temperature and was measured for future continuous compliance
determinations and was found to be within temperature range required by the regulations. Only catalyst
inlet pressure was measured during the test. However, given the engine and catalyst configuration,this
value should approximate the pressure drop across the catalyst. Operating load averaged 224 kW during
the test
In summary,the test results are acceptable. If you have any questions,please contact me at(919) 707-
8413 or [e-mail].
