Résumé
The Environmental Protection Agency (EPA) is approving a source-specific revision to the Arizona state implementation plan (SIP) that provides an alternative to Best Available Retrofit Technology (BART) for the Coronado Generating Station ("Coronado"), owned and operated by the Salt River Project Agricultural Improvement and Power District (SRP). The EPA has determined that the BART alternative for Coronado would provide greater reasonable progress toward natural visibility conditions than BART, based on the criteria established in the EPA's Regional Haze Rule. In conjunction with this approval, we are withdrawing those portions of the federal implementation plan (FIP) that address BART for Coronado. We are also codifying the removal of those portions of the Arizona SIP that have either been superseded by this approval of the SIP revision for Coronado or by previously- approved revisions to the Arizona SIP.
