The New Mexico Environment Department (NMED) has submitted updated regulations for receiving delegation of the Environmental Protection Agency (EPA) authority for implementation and enforcement of New Source Performance Standards (NSPS) and National Emission Standards for Hazardous Air Pollutants (NESHAPs) for all sources (both part 70 and non-part 70 sources). The delegation of authority under this action does not apply to sources located in Bernalillo County, New Mexico, or sources located in Indian Country. EPA is providing notice that it has approved delegation of certain NSPS to NMED, and taking direct final action to approve the delegation of certain NESHAPs to NMED.
