| 2012-17659 | Approval, Disapproval and Promulgation of Air Quality Implementation Plans; Arizona; Regional Haze State and Federal Implementation Plans | Proposed Rule | EPA is proposing to approve partially and disapprove partially a revision to Arizona's State Implementation Plan (SIP) to implement the regional haze program for the first planning period through July 31, 2018. This proposed action 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. EPA proposes to approve the State's determination that these sources are subject to BART, and to approve the emissions limits for sulfur dioxide (SO<INF>2</INF>) and particulate matter (PM<INF>10</INF>) at all the units. EPA proposes to disapprove the BART emissions limits for nitrogen oxides (NO<INF>X</INF>) at most of the units. EPA also proposes to promulgate a Federal Implementation Plan (FIP) containing new emissions limits for NO<INF>X</INF> as well as BART compliance requirements for the three facilities. We encourage the State to submit a revised SIP to replace all portions of our FIP, and we stand ready to work with the State to develop a revised plan. The Clean Air Act (CAA) requires states to prevent any future and remedy any existing man-made impairment of visibility in 156 national parks and wilderness areas designated as Class I areas. Arizona has a wealth of such areas. The three power plants affect visibility at 18 national parks and wilderness areas, including the Grand Canyon, Mesa Verde and the Petrified Forest. The State and EPA must work together to ensure that plans are in place to make progress toward natural visibility conditions at these national treasures. | 2012-07-20 | 2012 | 7 | https://www.federalregister.gov/documents/2012/07/20/2012-17659/approval-disapproval-and-promulgation-of-air-quality-implementation-plans-arizona-regional-haze | https://www.govinfo.gov/content/pkg/FR-2012-07-20/pdf/2012-17659.pdf | Environmental Protection Agency | 145 | EPA is proposing to approve partially and disapprove partially a revision to Arizona's State Implementation Plan (SIP) to implement the regional haze program for the first planning period through July 31, 2018.
