Air Quality State Implementation Plans - Approvals and Promulgations - Arizona - Revised Format for Materials (US Environmental Protection Agency Regulation) (EPA) (2018 Edition) The Law Library presents the complete text of the Air Quality State Implementation Plans - Approvals and Promulgations - Arizona - Revised Format for Materials (US Environmental Protection Agency Regulation) (EPA) (2018 Edition). Updated as of May 29, 2018 The Environmental Protection Agency (EPA) is revising the format for materials submitted by the State of Arizona that are incorporated by reference (IBR) into the Arizona State Implementation Plan (SIP). The regulations affected by this format change have all been previously submitted by the State of Arizona and approved by the EPA. This format revision will primarily affect the "Identification of plan" section, as well as the format of the SIP materials that will be available for public inspection at the National Archives and Records Administration (NARA) and the EPA Regional Office. The EPA is also adding a table in the "Identification of plan" section which summarizes the approval actions that the EPA has taken on the non-regulatory and quasi-regulatory portions of the Arizona SIP.

Air Quality State Implementation Plans - Approvals and Promulgations - Arizona - Regional Haze State and Federal Implementation Plans (US Environmental Protection Agency Regulation) (EPA) (2018 Edition) The Law Library presents the complete text of the Air Quality State Implementation Plans - Approvals and Promulgations - Arizona - Regional Haze State and Federal Implementation Plans (US Environmental Protection Agency Regulation) (EPA) (2018 Edition). Updated as of May 29, 2018 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.

Updated as of May 29, 2018 The Environmental Protection Agency (EPA) is taking final action to approve a source-specific revision to the Arizona state implementation plan that addresses the best available retrofit technology requirements for the Cholla Power Plant (Cholla). The EPA finds that the state implementation plan revision fulfills the requirements of the Clean Air Act and the EPA's Regional Haze Rule. In conjunction with this final approval, the EPA is taking final action to withdraw the federal implementation plan provisions applicable to Cholla. This also constitutes our action to address petitions for reconsideration granted by the EPA related to Cholla.

Approvals, Disapprovals and Promulgations of Air Quality Implementation Plans - Arizona - Regional Haze State and Federal Implementation Plans (US Environmental Protection Agency Regulation) (EPA) (2018 Edition) The Law Library presents the complete text of the Approvals, Disapprovals and Promulgations of Air Quality Implementation Plans - Arizona - Regional Haze State and Federal Implementation Plans (US Environmental Protection Agency Regulation) (EPA) (2018 Edition). Updated as of May 29, 2018 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 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.
