This initiative focuses on reducing heavy-duty engine emissions by 12.10% by 2007. Measures include biodiesel blends, Diesel Oxidation Catalysts, and newer engine repowering for a cleaner environment. Collaboration with fleet managers and increased funding proposals aim to expand statewide diesel emission reduction programs. The DEP Idle Rule, effective since December 15th, restricts idling to 5 minutes to further mitigate emissions.

Vision • More emphasis on voluntary measures • Address diesel emissions from the legacy fleet… • Collaborating with fleet managers and Transportation Directors to use state and federal grants aimed at reducing diesel emissions.
School Bus: Options for the older engines • Cleaner burning fuel blends (biodiesel) • Passive emission controls to complete the burn (Diesel Oxidation Catalyst) • Repowering with newer engines • Alternative fuels like CNG
Track Record • Manatee and Orange County (and others?) have used blends of biodiesel • Several of the urban school districts have taken advantage of grants and retrofitted school buses with diesel oxidation catalysts (DOC) • Current grant for DOCs on rural school districts in the north Florida Panhandle region- ongoing
Economic Stimulus Package Current proposal to increase funding for the Diesel Emission Reduction Act (DERA) from current levels ($50 million nationwide) to $300 million or more
This could mean • Expanded scope of school bus retrofits to a statewide program
DEP Idle Rule • Went into effect December 15th • Restricts idling to 5 minutes • Exceptions:
