The new Reciprocating Internal Combustion Engines (RICE) National Emission Standard for Hazardous Air Pollutants (NESHAP), 40 CFR 63, Subpart ZZZZ was promulgated on August 20, 2010 which covers RICE at major and area sources. Due to limited resources, DAQ has requested de-delegation of the area source portion of Subpart ZZZZ (RICE GACT) standard. On January 11, 2011, DAQ issued a memo to give interim guidance to DAQ staff on permitting and compliance of RICE at area sources.
