Clean Air Act Operating Permit Program Revision; California; Monterey Bay Air Resources District

The Environmental Protection Agency (EPA) is proposing to approve revisions to the Monterey Bay Air Resources District's (MBARD or "District") Title V Operating Permits Program. These revisions remove emergency affirmative defense provisions; align the rule with current title V requirements by removing permitting requirements for greenhouse gases; create procedures for electronic public noticing of permits in addition to newspaper noticing; and update formatting to match the MBARD's current rule format. This action is being taken in accordance with federal regulations and the Clean Air Act (CAA or "Act"). We are taking comments on these proposed revisions and plan to follow with a final action.
