The Environmental Protection Agency has announced a new initiative to track toxic air pollution at some of the nation’s schools. Louisville’s Air Pollution Control Board spokesman Matt Stull says the EPA will prioritize schools most at risk based on state input.“They’re going to be asking the states to comment on their draft list of schools, and if states feel strongly that a school should be added, or feel strongly that a school should be taken off, then EPA will take that into consideration," says Stull.Stull says that while the list is still subject to change, Louisville schools are not likely to be on it. He says that’s because of the city’s Strategic Toxic Air Reduction program, which includes monitoring sites for toxic emissions. He say the program has helped improve air quality.
