Promulgation of Air Quality Implementation Plans; Arizona; Regional Haze and Interstate Visibility Transport Federal Implementation Plan

This final action promulgates a Federal Implementation Plan (FIP) addressing the requirements of the Regional Haze Rule (RHR) and interstate visibility transport for the disapproved portions of Arizona's Regional Haze (RH) State Implementation Plan (SIP) as described in a final rule published in the Federal Register on July 30, 2013. In that action, we partially approved and partially disapproved the State's plan to implement the regional haze program for the first planning period. This final action includes our responses to comments on our proposed FIP published in the Federal Register on February 18, 2014. This final rule, together with a final rule published in the Federal Register on December 5, 2012, completes our FIP for the disapproved portions of Arizona's RH SIP. This final rule addresses the RHR's requirements for Best Available Retrofit Technology (BART), Reasonable Progress (RP), and a Long-term Strategy (LTS) as well as the interstate visibility transport requirements of the Clean Air Act (CAA) for pollutants that affect visibility in Arizona's 12 Class I areas and areas in nearby states. The BART sources addressed in this final FIP are Tucson Electric Power (TEP) Sundt Generating Station Unit 4, Lhoist North America (LNA) Nelson Lime Plant Kilns 1 and 2, ASARCO Incorporated Hayden Smelter, and Freeport-McMoRan Incorporated (FMMI) Miami Smelter. The reasonable progress sources addressed in the FIP are Phoenix Cement Company (PCC) Clarkdale Plant Kiln 4 and CalPortland Cement (CPC) Rillito Plant Kiln 4. EPA is prepared to work with the State on a SIP revision that would replace some or all elements of the FIP.
