## Abstract

The Environmental Protection Agency (EPA) is finalizing the approval of a revision to the Kentucky State Implementation Plan (SIP), submitted by the Commonwealth of Kentucky, through the Kentucky Division for Air Quality (KDAQ), on March 29, 2021. The revision was submitted by KDAQ on behalf of the Louisville Metro Air Pollution Control District (District or Jefferson County), which has jurisdiction over Jefferson County, Kentucky. The revision removes from the SIP several source-specific permits for a facility, which were previously incorporated by reference, and replaces them with a Board Order with emissions controls that are at least as stringent as those in the permits.
