Approval and Promulgation of Air Quality Implementation Plans; West Virginia; Removal of Source-Specific Requirements for Permanently Shutdown Facilities
The Environmental Protection Agency (EPA) is approving a state implementation plan (SIP) revision submitted by the State of West Virginia. This revision pertains to the removal of source-specific SIP requirements for the following five facilities in West Virginia that have permanently shutdown: Mountaineer Carbon Company; Standard Lafarge; Follansbee Steel Corporation; International Mill Service, Inc.; and Columbian Chemicals Company. These sources have permanently ceased operation; therefore, SIP requirements for these sources are obsolete and no longer necessary for attaining and maintaining the national ambient air quality standards (NAAQS). EPA is approving this revision in accordance with the requirements of the Clean Air Act (CAA).
Approval and Promulgation of Implementation Plans; South Dakota; Regional Haze 5-Year Progress Report State Implementation Plan
The Environmental Protection Agency (EPA) is proposing to approve South Dakota's regional haze progress report, submitted as a revision to its State Implementation Plan (SIP) by the South Dakota Department of Environment and Natural Resources (DENR). South Dakota's SIP revision addresses requirements of the Clean Air Act (CAA) and the EPA's rules that require states to submit periodic reports describing progress toward reasonable progress goals established for regional haze and a determination of the adequacy of the state's existing regional haze SIP. South Dakota's progress report explains that South Dakota has implemented the measures in the regional haze SIP due to be in place by the date of the progress report and that visibility in mandatory federal Class I areas affected by emissions from South Dakota sources is improving. The EPA is proposing approval of South Dakota's determination that the State's regional haze SIP is adequate to meet Reasonable Progress Goals (RPGs) for the first implementation period covering through 2018 and requires no substantive revision at this time.
Air Plan Approval; Connecticut; Infrastructure State Implementation Plan Requirements; Prevention of Significant Deterioration Permit Program Revisions
The Environmental Protection Agency (EPA) is proposing to approve elements of a State Implementation Plan (SIP) submission from Connecticut regarding the infrastructure requirements of the Clean Air Act (CAA or Act) for the 2012 fine particle (PM2.5) National Ambient Air Quality Standards (NAAQS), and a SIP submission addressing interstate transport requirements of the CAA for the 2006 PM2.5 NAAQS. In addition, we are proposing to approve one statute included in the SIP for the 2012 PM2.5 NAAQS. The infrastructure requirements are designed to ensure that the structural components of each state's air quality management program are adequate to meet the state's responsibilities under the CAA. The EPA is also proposing to approve revisions to the SIP submitted by Connecticut on October 18, 2017, satisfying Connecticut's earlier commitment to adopt and submit provisions that meet certain requirements of the federal Prevention of Significant Deterioration (PSD) permit program. In addition, we are proposing to convert the June 3, 2016 conditional approval for elements of Connecticut's infrastructure SIP regarding PSD requirements to treat nitrogen oxides (NOX) as a precursor to ozone and to establish a minor source baseline date for PM2.5 emissions. This action is being taken under the Clean Air Act.
Air Plan Approval; Vermont; Nonattainment New Source Review and Prevention of Significant Deterioration Permit Program Revisions; Infrastructure Requirements for National Ambient Air Quality Standards
The Environmental Protection Agency (EPA) is approving several different revisions to the State Implementation Plan (SIP) submitted to the EPA by the Vermont Department of Environmental Conservation (VT DEC). On May 23, 2017, Vermont submitted revisions to the EPA satisfying the VT DEC's earlier commitment to adopt and submit revisions that meet certain requirements of the Federal Prevention of Significant Deterioration (PSD) air permit program. Vermont's submission also included revisions relating to the federal nonattainment new source review (NNSR) permit program. This action approves those revisions and also fully approves certain elements of Vermont's infrastructure SIPs (ISIPs), which were conditionally approved by the EPA on June 27, 2017. Additionally, the EPA is approving several other minor regulatory changes to the SIP submitted by VT DEC on May 23, 2017. This action is being taken in accordance with the Clean Air Act.
Approval of California Air Plan Revisions, Antelope Valley Air Quality Management District
The Environmental Protection Agency (EPA) is proposing to approve a revision to the Antelope Valley Air Quality Management District (AVAQMD) portion of the California State Implementation Plan (SIP). This revision concerns the emissions of volatile organic compounds (VOCs) from motor vehicle assembly coating operations. We are proposing to approve a local rule to regulate these emission sources under the Clean Air Act (CAA or the Act). We are taking comments on this proposal and plan to follow with a final action.
Air Plan Approval; Oregon; Regional Haze Progress Report
The Environmental Protection Agency (EPA) is proposing to approve a revision to the Oregon Regional Haze State Implementation Plan (SIP), submitted by the State of Oregon on July 18, 2017. Oregon submitted its Regional Haze Progress Report (``progress report'' or ``report'') and a negative declaration stating that further revision of the existing regional haze SIP is not needed at this time. Oregon submitted both the progress report and the negative declaration in the form of implementation plan revisions as required by federal regulations. The progress report addresses the federal Regional Haze Rule (RHR) requirements under the Clean Air Act (CAA) to submit a report describing progress in achieving reasonable progress goals (RPGs) established for regional haze and a determination of the adequacy of the state's existing plan addressing regional haze.
