Supported by local health and environmental activists, the Air Pollution Control Board in Louisville, Ky., made admirable history last week with the Strategic Toxic Air Reduction (STAR) program. Three years ago, according to the Courier-Journal, the EPA rated the city’s air the worst in the entire Southeast, but as of July 1, Louisville will have some of the nation’s strongest, healthiest air quality standards. The plan will reduce 37 specific chemicals emitted by industrial activity; programs to reduce emissions from cars and other sources will be implemented soon.
