| 2010-25309 | Approval and Promulgation of Implementation Plans; State of Mississippi: Prevention of Significant Deterioration Rules: Nitrogen Oxide as a Precursor to Ozone | Proposed Rule | EPA is proposing to approve a portion of a revision to the Mississippi State Implementation Plan (SIP), submitted by the Mississippi Department of Environmental Quality (MDEQ), to EPA on November 28, 2007. The revision modifies Mississippi's prevention of significant deterioration (PSD) permitting regulations in the SIP to address permit requirements promulgated in the 1997 8-Hour Ozone National Ambient Air Quality Standards (NAAQS) Implementation Rule- Phase II (hereafter referred to as the "Ozone Implementation New Source Review (NSR) Update"). The Ozone Implementation NSR Update revised permit requirements relating to the implementation of the 1997 8-hour ozone NAAQS specifically incorporating nitrogen oxides (NO<INF>X</INF>) as a precursor to ozone. Specifically, this SIP revision incorporates by reference the Ozone Implementation NSR Update federal regulations into the Mississippi SIP through Air Pollution Control Section 5 (APC-S-5) "Regulations for the Prevention of Significant Deterioration of Air Quality." EPA's approval of Mississippi's incorporation by reference of the Ozone Implementation NSR Update federal regulations, including provisions to recognize NO<INF>X</INF> as an ozone precursor, into the Mississippi SIP, is based on EPA's determination that Mississippi's revision related to these provisions complies with current Federal requirements and section 110 of the Clean Air Act (CAA). EPA is not taking action on two portions of Mississippi's November 28, 2007 submittal. The first is regarding Mississippi's incorporation by reference of provisions promulgated by EPA on May 1, 2007, which exclude from the NSR major source permitting requirements "chemical process plants" that produce ethanol through a natural fermentation process (hereafter referred to as the "Ethanol Rule"). See 72 FR 24060. EPA may consider further action for the aforementioned provision in a future rulemaking. The second is Mississippi's compliance with Section 110(a)(2)(D)(i) of the CAA regarding interstate air pollution transport for the 1997 8-hour ozone and fine particulate matter NAAQS as it pertains to the prevention of significant deterioration of air quality and visibility. EPA is also not addressing Mississippi's submission regarding interstate transport in today's action. | 2010-10-07 | 2010 | 10 | https://www.federalregister.gov/documents/2010/10/07/2010-25309/approval-and-promulgation-of-implementation-plans-state-of-mississippi-prevention-of-significant | https://www.govinfo.gov/content/pkg/FR-2010-10-07/pdf/2010-25309.pdf | Environmental Protection Agency | 145 | EPA is proposing to approve a portion of a revision to the Mississippi State Implementation Plan (SIP), submitted by the Mississippi Department of Environmental Quality (MDEQ), to EPA on November 28, 2007.
