On June 12, 2008, Governor Deval Patrick announced the launch of MassCleanDiesel, the nation's first fully funded statewide program designed to reduce air pollution from school buses.

All eligible diesel-powered school buses will receive retrofits to keep engine fumes away from children on buses and reduce exhaust emissions to the air, at no expense to bus owners. The results: cleaner rides for kids and healthier air for everyone.

"The buses that take our children to school should not foul the air breathed by those same children, and this program will help put that situation to an end," said Governor Patrick at a press event held at the Julia F. Callahan School in Lynn. "I applaud the City of Lynn and its school-bus operator, North Reading Transportation Co., for stepping forward as the first to volunteer for this new program, and I call on all school districts in the Commonwealth and their bus companies to take part."

Bus owners can now request retrofits using MassDEP's online application, and should contact us to learn more about the program and how to participate.
