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). The official record describes this as a completed action.
