## Abstract

On July 5, 2007, EPA published in the Federal Register a final rule redesignating the Kentucky portion of the bi-state Louisville 8- hour ozone nonattainment area to attainment for the 8-hour ozone National Ambient Air Quality Standard (NAAQS). EPA inadvertently omitted the State effective date in the regulatory text in the final rule for the Louisville 8-hour ozone maintenance plan. This action corrects the July 5, 2007, final rule by adding a State effective date of September 29, 2006.
