New Source Performance Standards and National Emission Standards for Hazardous Air Pollutants; Delegation of Authority to New Mexico

The New Mexico Environment Department (NMED) has submitted updated regulations for receiving delegation and approval of a program for the implementation and enforcement of certain New Source Performance Standards (NSPS) and National Emission Standards for Hazardous Air Pollutants (NESHAP) for all sources (both Title V and non-Title V sources). These updated regulations apply to certain NSPS promulgated by the EPA and amended between September 24, 2013 and January 15, 2017; certain NESHAP promulgated by the EPA and amended between January 1, 2011 and January 15, 2017; and other NESHAP promulgated by the EPA and amended between August 30, 2013 and January 15, 2017, as adopted by the NMED. The delegation of authority under this action does not apply to sources located in Bernalillo County, New Mexico, or to sources located in areas defined as Indian Country. The EPA is providing notice that it is updating the delegation of certain NSPS to NMED, and taking final action to approve the delegation of certain NESHAP to NMED.
