Environmental Protection Agency August 30, 2021 – Federal Register Recent Federal Regulation Documents

The Clean Air Act (CAA) requires each State Implementation Plan (SIP) to contain adequate provisions prohibiting emissions that will have certain adverse air quality effects in other states. The State of Connecticut made a submission to the Environmental Protection Agency (EPA) to address these requirements for the 2015 ozone National Ambient Air Quality Standards (NAAQS). EPA is proposing to approve the submission as meeting the requirement that each SIP contain adequate provisions to prohibit emissions that will significantly contribute to nonattainment or interfere with maintenance of the 2015 ozone NAAQS in any other state.

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), as provided for under previously approved delegation mechanisms. The updated state regulations incorporate by reference certain NESHAP promulgated by the Environmental Protection Agency (EPA) as they existed through June 30, 2019. The EPA is proposing to approve ODEQ's requested delegation update. The proposed delegation of authority under this action applies to sources located in certain areas of Indian country as discussed herein.
