Connecticut Clean School Bus Program
{School Bus Picture}
Connecticut’s Clean School Bus Program has been successful in satisfying the demand for emission controls on school buses in the state.  Between 2004 and 2009, 839 Connecticut school buses were retrofitted with emission controls to reduce the exposure of children to diesel exhaust from school buses. In 2007, the Connecticut General Assembly passed Public Act No. 07-4 Sections 16-19 (The Act), which provided funding to reimburse more school districts and municipalities, statewide, for the purchase, installation, and warranty of emission controls and closed crankcase ventilation systems (CCVs). Municipalities and school districts could select vendors, from state procurement contracts developed for the program, to provide the emission controls and CCVs for their school buses.

In 2008, the Department of Energy and Environmental Protection (DEEP) secured a State Diesel Emission Reduction Act (DERA) grant from the U.S. Environmental Protection Agency (EPA) to provide supplemental funding for the program. In the first year of this State DERA grant, funds were used to bridge the gap between the legislative price caps under The Act and the contract prices for EPA-verified diesel oxidation catalysts (DOCs) and CCVs. DEEP completed the supplemental funding program in June of 2009, when funding lapsed under The Act. In the first half of 2009, 23 school districts had retrofitted 339 school buses with DOCs and CCVs, bringing the state school bus retrofit total to nearly 1200.

At the end of 2009, using 100% DERA funding, one additional school district participated in the Clean School Bus Program, bringing the total number of Connecticut Clean School Bus retrofits to 353.  By the end of 2010, this program had satisfied the demand for school bus retrofits in Connecticut.
