Summary

The Environmental Protection Agency (EPA) is approving two separate but related submissions (one of which includes multiple components) provided by the Commonwealth of Kentucky, through the Kentucky Division of Air Quality (KDAQ), in relation to attainment of the 2010 Sulfur Dioxide (SO<INF>2</INF>) national ambient air quality standards (NAAQS) for the Kentucky portion of the Campbell-Clermont, Kentucky-Ohio 2010 1-hour SO<INF>2</INF> nonattainment area (hereafter referred to as the "Campbell-Clermont, KY-OH Area" or "Area"). On March 31, 2015, KDAQ submitted a request for EPA to determine that the Campbell-Clermont, KY-OH Area attained the 2010 1-hour SO<INF>2</INF> NAAQS. Subsequently, on February 22, 2016, KDAQ submitted a request for EPA to redesignate the Campbell County portion of Kentucky that is within the Campbell-Clermont, KY-OH Area to attainment for the 2010 1- hour SO<INF>2</INF> NAAQS, and to approve a State Implementation Plan (SIP) revision containing a maintenance plan, base year inventory, and reasonably available control measures (RACM) determination for the Kentucky portion of the Area. EPA is approving the Commonwealth's RACM determination; the base year emissions inventory for the Kentucky portion of the Area; the Commonwealth's request for a clean data determination; and the Commonwealth's plan for maintaining attainment of the 2010 1-hour SO<INF>2</INF> NAAQS; and is redesignating the Kentucky portion of the Area to attainment for the 2010 1-hour SO<INF>2</INF> NAAQS.
