Thirty-five engines, providing cooling, heating, and power have been tested for compliance purposes across four different states (USEPA Regions 1 and 2) under the provisions of Subpart JJJJ (Title 40, CFR, Part 60). A “blanket” source test protocol was submitted to the USEPA encompassing EPA test methods 3A, 4, 7E, 10, 18, and 25A for all engines that have been and will be tested. All engines are identical in model number, size, air pollution controls, and kilowatt output. Since the engines were manufactured by the same company and are identical the “blanket” compliance protocol enabled the USEPA to approve the test procedures and allow for timely testing. This alleviated the submittal of 35 different compliance test protocols and the review process associated with that many submittals. This also was a very cost effective means and savings to our client. Prior to each test program an engine “fact sheet” was submitted to the USEPA which detailed the specifics of each engine (block number, CHP unit).
Sixteen of these engines required the use of a portable CEMS which enabled sampling to take place in crowded/cramped areas not accessible with a trailer mounted CEMS. This test program also saw the use of a VIG Model 200 total hydrocarbon (THC) and non-methane hydrocarbon (NMHC) analyzer equipped with gas chromatography for the speciation of methane and real time analysis of NMHC.
