The U.S. Environmental Protection Agency (EPA or Agency) is approving a State Implementation Plan (SIP) revision submitted by the Commonwealth of Kentucky, through the Kentucky Division for Air Quality (DAQ), on February 20, 2025. The SIP revision includes the second 10- year maintenance plan for the Kentucky portion of the Campbell- Clermont, Kentucky-Ohio maintenance area ("Campbell-Clermont, KY-OH Area" or "Area") for the 2010 1-hour sulfur dioxide (SO<INF>2</INF>) National Ambient Air Quality Standards (NAAQS). The Kentucky portion of the Area is comprised of a part of Campbell County. The EPA is approving Kentucky's second 10-year maintenance plan for the Kentucky portion of the Area because the Commonwealth has demonstrated that it is consistent with the Clean Air Act (CAA or Act).
