Reciprocating Internal Combustion Engine (RICE) MACT Reference Materials

REMINDER: Initial notifications for applicability to 40 CFR 63, Subpart ZZZZ, Reciprocating Internal Combustion Engine (RICE) NESHAP were due by February 16, 2011, to both WVDEP-DAQ and to U. S. EPA Region III.

EPA's National Emission Standard for Hazardous Air Pollutants (NESHAP) rule for reciprocating internal combustion engines (RICE) has undergone numerous changes since its initial proposal in 2002.  The federal rule now affects RICE engines located at both major and area sources of hazardous air pollutants (HAPS).  A major source of HAPs is one in which the maximum plantwide potential to emit of all HAPs (including fugitive emissions) is greater to or equal to 10 tpy of a single HAP or HAP compound category, or is greater than or equal to 25 tpy of aggregated HAPs or HAP compound categories.  An area source of HAPs is one that is not a major source of HAPs (that is, one that is a minor source of HAPs).

The oil and natural gas industry sector has a unique definition of major source of HAPs under Section 112(n)(4) of the 1990 Clean Air Act amendments.  For oil and gas sources, HAP PTE may be aggregated with respect to each surface site for determination of major HAP source status instead of plantwide (and as consistent with the definition of major source in the rule).  However, for permitting purposes, all emissions continue to be on a plantwide basis regardless of the number of surface sites.  Certain engines are required to test emissions by October 19, 2013, and most engines have work practice requirements.
