The Environmental Protection Agency (EPA) has approved a change to the State Implementation Plan (SIP) submitted by Kentucky, which updates the status designations of areas within the state to align with federal standards for air quality. This update affects several National Ambient Air Quality Standards (NAAQS) and ensures that Kentucky's regulations are in line with the Clean Air Act. The changes impact designations for pollutants like ozone, particulate matter, and sulfur dioxide, confirming how these areas meet or do not meet federal air quality standards. The effective date of this rule is March 31, 2021.

Kentucky changed some rules to make sure their air stays clean, just like the big boss in the sky, the EPA, wants. It’s like making sure their color books match up with the big coloring book everyone else uses.
