  5. 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

  6. 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
