Ill. Admin. Code tit. 35 § 241.102
"Adjusted loaded vehicle weight (ALVW)" means the numerical average of the vehicle curb weight and the GVWR, as designated by the manufacturer.
"Capable of being centrally fueled" means a motor vehicle that could be refueled 100 percent of the time at a location that is owned, operated, or controlled by the covered fleet owner or operator, or is under contract with the covered fleet owner or operator. Motor vehicles that are under normal conditions garaged at a personal residence are not considered to be capable of being centrally fueled and are exempt from the program unless they are, in fact, centrally fueled. The fact that one or more motor vehicles in a fleet are not capable of being centrally fueled does not exempt an entire fleet from the program. To determine whether a motor vehicle is capable of being centrally fueled 100 percent of the time, the owner or operator shall perform the following calculation for each motor vehicle in the fleet for which an exemption under Section 241.111(a)(10) is being claimed, and, annually thereafter, if additional new covered fleet vehicles are acquired and an exemption is claimed under Section 241.111(a)(10):
For each motor vehicle, sum the miles it is driven for a three month period beginning May 1, or the first day of the first full month in which the fleet may be covered.
Divide total miles for the given time period for each motor vehicle by its number of round trips. A round trip occurs each time a motor vehicle leaves its location or a contracted refueling station and returns to its location or a contracted refueling station.
If the average number of miles per round trip for the motor vehicle is less than 300 miles, then the motor vehicle is capable of being centrally fueled.
"Centrally fueled" means a motor vehicle that is fueled 100 percent of the time at a location that is owned, operated, or controlled by the covered fleet owner or operator, or is under contract with the covered fleet owner or operator. Any motor vehicle that is under normal operations garaged at a personal residence at night but that is, in fact, centrally fueled 100 percent of the time shall be considered to be centrally fueled for the purpose of this definition. The fact that one or more motor vehicles in a fleet are not centrally fueled does not exempt an entire fleet from the program.
"Clean alternative fuel" means any fuel (including methanol; ethanol; or other alcohols containing 85 percent or more by volume of such alcohol with gasoline or other fuels; reformulated gasoline; diesel; natural gas; liquefied petroleum gas; and hydrogen) or power source (including electricity) used in a clean fuel vehicle that complies with the standards and requirements applicable to such motor vehicle under this Part when using such fuel or power source. In the case of any flexible fueled vehicle or dual fueled vehicle, the term "clean alternative fuel" means only a fuel with respect to which such motor vehicle was certified as a clean fuel vehicle meeting the emission standards applicable to such motor vehicle weight class as set forth in Appendix A and in 40 CFR Part 88, Subpart A, incorporated by reference at Section 241.104 of this Subpart, when operating on clean alternative fuel.
"Clean fuel vehicle" means a motor vehicle in a class or category of motor vehicles (e.g., LDVs, LDTs, or HDVs) which have been certified by USEPA to meet the clean fuel vehicle standards applicable under Subpart B of this Part.
"Control" shall have the following meanings:

Two or more firms have common officers, in whole or in substantial part, who are responsible for the day-to-day operation of the companies; or
One firm leases, operates, supervises or in 51 percent or greater part owns equipment and/or facilities used by another person or firm, or has equity ownership of 51 percent or more of another firm.
When it is used to refer to the management of motor vehicles, means a person has the authority to decide who can operate a particular motor vehicle, and the purposes for which the motor vehicle can be operated.
When it is used to refer to the management of people, means a person has the authority to direct the activities of another person or employee in a precise situation, such as at the workplace.

"Covered fleet" means ten or more covered fleet vehicles which are owned or operated by a person. In determining the number of covered fleet vehicles owned or operated by a person for purposes of this Part, all motor vehicles owned or operated, leased or otherwise controlled by such person, and by any person who controls such person, and by any person under common control with such person, shall be treated as owned by such person. Covered fleets include distributed and partially covered fleets.
