Illinois Statutes Chapter 625. Vehicles § 5/12-705.1. Required use of biodiesel by certain vehicles

(a) Beginning July 1, 2006, any diesel powered vehicle owned or operated by this State, any county or unit of local government, any school district, any community college or public college or university, or any mass transit agency must, when refueling at a bulk central fueling facility, use a biodiesel blend that contains 5% biodiesel, as those terms are defined in the Illinois Renewable Fuels Development Program Act, where available, unless the engine is designed or retrofitted to operate on a higher percentage of biodiesel or on ultra low sulfur fuel.

(b) Nothing in this Section prohibits any unit of government from using a biodiesel blend containing more than 2% biodiesel.

(c) As used in this Section, a “bulk central fueling facility” means a non-commercial fueling facility whose primary purpose is the fueling of vehicles owned or operated by the State, a county or unit of local government, a school district, a community college or public college or university, or a mass transit agency.

(d) The Secretary of Transportation shall adopt rules for implementing this Section.
