The Oklahoma Department of Environmental Quality (ODEQ) has submitted updated regulations for receiving delegation and approval of its program for the implementation and enforcement of certain National Emission Standards for Hazardous Air Pollutants (NESHAP) for all sources (both part 70 and non-part 70 sources), as provided for under previously approved delegation mechanisms. The updated state regulations incorporate by reference certain NESHAP promulgated by the EPA at parts 61 and 63, as they existed through September 1, 2016.
