Thirteen Indiana businesses and school systems are changing their diesel vehicle fleets to improve air quality.
The Indiana Department of Environmental Management says a federal grant will help pay for retrofitting school buses, technology to reduce idling by tractor trucks, towboats and locomotives, and fuel-efficient tires and aerodynamic trim for tractors and trailers. Dollar amounts weren't released.
The school systems getting grant money are the Avon Schools, Carmel Schools and Pike Township Schools, all in and around Indianapolis.
The 10 companies include seven trucking firms. The others are Commercial Barge Lines of Jeffersonville, Primex Plastics of Richmond and Steel Dynamics in Pittsboro.
