Arlington County implemented B20 biodiesel as a means to reduce the environmental impact diesel vehicles were having in the county. The impetus came from calls from citizens about the exhaust plume above the school bus parking during morning start-up and the visible exhaust from heavy vehicles such as fire trucks.

Arlington’s fleet management team prepared for the first delivery of B20 by cleaning storage tanks, adding fuel dispenser filters, and educating drivers on the potential for fuel filter clogging during the early stages of the cut-over. In September of 2001, the county received its first shipment of B20.
