Don’t Forget Your RICE MACT Monitoring Plan

Considering the upcoming deadline for the 40 CFR 63 Subpart ZZZZ National Emission Standard for Hazardous Air Pollutants for Reciprocating Internal Combustion Engines (the “RICE MACT”), we thought this blog post courtesy of Trinity Consultants was appropriate...

Under the 40 CFR 63 Subpart ZZZZ National Emission Standard for Hazardous Air Pollutants for Reciprocating Internal Combustion Engines (the “RICE MACT”), the April 17th deadline is fast approaching for initial performance testing, or catalyst activity testing, as applicable, for two broad categories of engines with emissions standards: (1) existing SI RICE between 100 and 500 hp at major sources, and, (2) existing 4S SI RICE greater than 500 hp at non-remote area sources. To comply with the RICE MACT emissions standards, EPA assumes that the majority of these engines will need catalytic control, i.e., oxidation catalyst for the lean burn engines and three-way / non-selective catalyst for the rich burn engines. For any engine controlled by catalyst and subject to initial performance testing, the RICE MACT requires ongoing monitoring of parameters established during the testing. This monitoring must be completed according to a site-specific monitoring plan, and this plan should be in place by the date of the initial performance test, which, for the engine categories mentioned above, is just around the corner. Along with the 60-day notice and other items on your performance test to-do list, plan to carve out some time for developing your monitoring plan(s). Some details of what goes into the required monitoring plan are discussed below.
