What the agency says

The Environmental Protection Agency (EPA) is making an interim final determination that the California Air Resources Board (CARB) has submitted a Clean Air Act (CAA or "Act") state implementation plan (SIP) revision on behalf of the Antelope Valley Air Quality Management District (AVAQMD or "District") that corrects deficiencies concerning the District's New Source Review (NSR) stationary source permitting program. This determination is based on a proposed approval, published elsewhere in this issue of the Federal Register, of AVAQMD Rules 1301, 1302 (except 1302(C)(5) and 1302(C)(7)(c)), 1303, 1304, 1305, and 1309. The effect of this interim final determination is to stay the application of the offset sanction and to defer the action of the highway sanction that were triggered by the EPA's limited disapproval of AVAQMD Rules 1301, 1302 (except 1302(C)(5) and 1302(C)(7)(c)), 1303, 1304, 1305, 1309 on July 3, 2023.
