Revisions to California State Implementation Plan; Bay Area Air Quality Management District; Stationary Sources; New Source Review

The Environmental Protection Agency (EPA) is finalizing action on revisions to the Bay Area Air Quality Management District (BAAQMD or District) portion of the California State Implementation Plan (SIP). These revisions concern permit program rules governing the issuance of permits for stationary sources, including review and permitting of major sources and major modifications under parts C and D of title I of the Clean Air Act (CAA), and the issuance and banking of Emission Reduction Credits. The revisions correct deficiencies in BAAQMD Regulation 2, Rules 1 and 2, and Regulation 2, Rule 4, previously identified by the EPA in final rules dated August 1, 2016, and December 4, 2017, respectively. Approval of this SIP revision terminates the sanctions clock and federal implementation plan (FIP) clock that were triggered by the EPA's limited disapproval of a related SIP submission on August 1, 2016.
