In addition to idle-free school zones, what else should WCSD’s do to reduce air pollution from diesel buses?
1. Continue to seek funding for retrofitting buses. 2. Procure a variety of diesel fuel that meets ultra-low sulfur (15 ppm) specifications. 3. Replace all older (pre-1997) buses. 4. When school districts put out a Request for Bids (RFB), state that buses have to have the best available retrofit technology as a specification in the contract. 5. Allocate the cleanest buses to the longest routes.
