LOUISVILLE, Ky. (WDRB) -- Louisville Mayor Craig Greenberg said he and Gov. Andy Beshear have written to the U.S. Environmental Protection Agency asking for the city's reformulated gas requirement to be lifted.

Greenberg said the U.S. Environmental Protection Agency was concerned with air quality in Louisville in the 1990s and enforced a rule in which gas stations could only sell reformulated gas. But that gas is more expensive.

He said Louisville is now in a spot where the city could go back to using conventional gas because the city's air quality has improved.

"That's thanks to innovation and improvements by industry, the work of multiple community organizations, and federal, state and Metro government programs all working together over the past 20 years to make our city healthier and our air cleaner," Greenberg said in a news conference Tuesday.

The change could save money at the pump.

"We believe that we are going to be in compliance, and now is the time to acknowledge the improvement in our air quality," Greenberg said.

There's not a timeline or when the city will hear back. Greenberg said it is in the hands of the EPA.

According to the U.S. Energy Information Administration, the national average for the week of Feb. 10, 2025, for regular gas per gallon was $3.128, while the national average for reformulated gas was $3.357.
