The Environmental Protection Agency (EPA) has proposed to deny Kentucky's request to redesignate the Kentucky portion of the Louisville, KY-IN area from a nonattainment to an attainment zone for the 2015 8-hour ozone standards. This decision is based on the area's failure to meet the air quality standards due to violations recorded in 2023. The EPA is making no decisions on Kentucky's maintenance plan, nor on emissions budgets for nitrogen oxides and volatile organic compounds. Public comments on this proposed action are being accepted until February 3, 2025.
Simple Explanation
The EPA is saying "no" to Kentucky's idea to call part of Louisville's air clean because it's not meeting the rules yet. They're also not deciding on any plans to keep the air clean or how to cut down on air pollution right now.
