## Abstract

The Texas Commission on Environmental Quality (TCEQ) has submitted updated regulations for receiving delegation of the EPA authority for implementation and enforcement of National Emission Standards for Hazardous Air Pollutants (NESHAPs) for all sources (both part 70 and non-part 70 sources). These regulations apply to certain NESHAPs promulgated by the EPA, as amended between April 24, 2013 and August 3, 2016. The delegation of authority under this action does not apply to sources located in Indian Country. The EPA is taking direct final action to approve the delegation of certain NESHAPs to TCEQ.
