Environmental Protection Agency February 2, 2023 – Federal Register Recent Federal Regulation Documents

The Environmental Protection Agency (EPA) is proposing an approval, a partial approval and partial disapproval, and a limited approval and limited disapproval of certain revisions to the Clark County portion of the Nevada State Implementation Plan (SIP). These revisions primarily concern the Clark County Department of Environment and Sustainability's (``DES'' or ``Department'') general definitions rule and New Source Review (NSR) permitting program for new and modified sources of air pollution under the Clean Air Act (CAA or ``Act''). We are taking comments on this proposal and plan to follow with a final action.
