RICE NESHAP Compliance
Overview
RICE NESHAP is the acronym for the US EPA rule for “reciprocating internal combustion engines national emission standards for hazardous air pollutants”. The RICE NESHAP rule requires implementation of new maintenance and reporting practices for existing stationary engines. Many of these engines will also require retrofit with catalytic emission control.
Compliance Dates
May 3, 2013 for existing CI engines
