The Environmental Protection Agency (EPA) is proposing to approve the State Implementation Plan (SIP) revision that the State of New Hampshire submitted to EPA on January 31, 2017 for attaining the 1- hour sulfur dioxide (SO<INF>2</INF>) primary national ambient air quality standard (NAAQS) for the Central New Hampshire Nonattainment Area. This plan (herein called a "nonattainment plan") includes New Hampshire's attainment demonstration and other elements required under the Clean Air Act (CAA). In addition to an attainment demonstration, the nonattainment plan addresses the requirement for meeting reasonable further progress (RFP) toward attainment of the NAAQS, reasonably available control measures and reasonably available control technology (RACM/RACT), base-year and projection-year emission inventories, and contingency measures. As a part of approving the attainment demonstration, EPA is also proposing to approve SO<INF>2</INF> emission limits and associated compliance parameters for Merrimack Station into the New Hampshire SIP. EPA proposes to conclude that New Hampshire has appropriately demonstrated that the nonattainment plan provisions provide for attainment of the 2010 1-hour primary SO<INF>2</INF> NAAQS in the Central New Hampshire Nonattainment Area by the applicable attainment date and that the nonattainment plan meets the other applicable requirements under the CAA.
