Summary

The Environmental Protection Agency (EPA) is proposing to approve a State Implementation Plan (SIP) revision submitted by the State of Tennessee, through the Tennessee Department of Environment and Conservation (TDEC), to EPA on May 12, 2017, for attaining the 2010 1- hour sulfur dioxide (SO<INF>2</INF>) primary national ambient air quality standard (NAAQS) for the Sullivan County SO<INF>2</INF> nonattainment area (hereafter referred to as the "Sullivan County Area" or "Area"). The Sullivan County Area is comprised of a portion of Sullivan County in Tennessee surrounding the Eastman Chemical Company (hereafter referred to as "Eastman"). This plan (herein called a "nonattainment plan or SIP" or "attainment plan or SIP") includes Tennessee's attainment demonstration and other elements required under the Clean Air Act (CAA or Act). In addition to an attainment demonstration, the 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 emissions inventories, enforceable emissions limitations and control measures, and contingency measures. EPA proposes to conclude that Tennessee has appropriately demonstrated that the plan's provisions provide for attainment of the 2010 1-hour primary SO<INF>2</INF> NAAQS in the Sullivan County Area and that the plan meets the other applicable requirements under the CAA.
