Environmental Protection Agency
EPA is taking final action to approve in part and disapprove in part a portion of Arizona's State Implementation Plan (SIP) submittal for its regional haze program and to promulgate a Federal Implementation Plan (FIP) for the disapproved elements of the SIP. The State and Federal plans are to implement the regional haze program in Arizona for the first planning period through 2018. This final rule addresses only the portion of the SIP related to Arizona's determination of Best Available Retrofit Technology (BART) to control emissions from eight units at three electric generating stations: Apache Generating Station, Cholla Power Plant and Coronado Generating Station. Consistent with our proposal, EPA approves in this final rule the State's determination that the three sources are subject to BART, and approves the State's emissions limits for sulfur dioxide (SO<INF>2</INF>) and particulate matter less than or equal to 10 micrometers (PM<INF>10</INF>) at all the units, but disapproves Arizona's BART emissions limits for nitrogen oxides (NO<INF>X</INF>) at the coal-fired units of the three power plants. We also are promulgating a FIP that contains new emissions limits for NO<INF>X</INF> at these coal-fired units and compliance schedules for implementation of BART as well as requirements for equipment maintenance, monitoring, recordkeeping and reporting for all units and all pollutants at the three sources. In today's action, we are revising some elements of the proposed FIP in response to comments and additional information that we received.

Environmental Protection Agency 40 CFR Part 52 [EPA-R09-OAR-2012-0021, FRL-9754-3] AGENCY: Environmental Protection Agency (EPA). ACTION: Final rule. SUMMARY: EPA is taking final action to approve in part and disapprove in part a portion of Arizona's State Implementation Plan (SIP) submittal for its regional haze program and to promulgate a Federal Implementation Plan (FIP) for the disapproved elements of the SIP. The State and Federal plans are to implement the regional haze program in Arizona for the first planning period through 2018. This final rule addresses only the portion of the SIP related to Arizona's determination of Best Available Retrofit Technology (BART) to control emissions from eight units at three electric generating stations: Apache Generating Station, Cholla Power Plant and Coronado Generating Station. Consistent with our proposal, EPA approves in this final rule the State's determination that the three sources are subject to BART, and approves the State's emissions limits for sulfur dioxide (SO 2 ) and particulate matter less than or equal to 10 micrometers (PM 10 ) at all the units, but disapproves Arizona's BART emissions limits for nitrogen oxides (NO X ) at the coal-fired units of the three power plants. We also are promulgating a FIP that contains new emissions limits for NO X at these coal-fired units and compliance schedules for implementation of BART as well as requirements for equipment maintenance, monitoring, recordkeeping and reporting for all…
