Federal regulators have agreed to decide whether certain air-quality regulations in Kentucky are adequate, according to the Kentucky Environmental Foundation.
The Berea-based foundation had argued in a lawsuit that the U.S. Environmental Protection Agency failed to make a decision on the regulations within the time required by law.
In an agreement reached as part of the lawsuit, EPA agreed to make a decision on Kentucky's plan for controlling ozone by April 15, the foundation announced Thursday.
The foundation is concerned that the state's proposed plan downplays ozone concentrations in Lexington, Ashland and the Edmonson County area, executive director Elizabeth Crowe said in a release.

The foundation also questions the state's plan on regulating visible haze. The EPA agreed to approve or disapprove the state's haze plan by March 15, 2012.
