What are the engine model years verified for use with the Program-approved diesel particulate filters (DPFs)?
The Program allows applicants to apply for funding for installation of qualified diesel particulate filters, as listed on the U.S. Environmental Protection Agency’s (EPA) verified retrofit technology list or the California Air Resources Board’s (CARB) level 3 verified retrofit technology list. The technology must be on the list as of the date the application is approved (expected mid- to late March 2005 for the first round of applications). Based on the combustion technology used to attain current emission standards, some post 2002 engines might not be verified for a particular filter. Because Program funds may only be used for EPA- or CARB-verified filters, only verified filters for the specific bus engine are eligible to be retrofitted with diesel particulate filters as part of the Clean Buses for Kids Program.
