ATCP 94.120(1)(1) “Alternative liquid automotive fuel” includes all of the following: ATCP 94.120(1)(a)(a) Mixtures containing more than 16.1 percent by volume of butanol or 15 percent by volume of methanol, denatured ethanol, other alcohols, or any combination thereof with gasoline or other fuels. ATCP 94.120(2)(b)(b) For an alternative liquid automotive fuel other than biodiesel, biomass-based diesel, biodiesel blends, biomass-based diesel blends, and ethanol flex fuels, the commonly used name of the fuel with a disclosure of the amount, expressed as the minimum percentage by volume, of the principal component of the fuel. A disclosure of other components, expressed as the minimum percentage by volume, may be included, if desired. ATCP 94.120(2)(c)(c) For biomass-based diesel, biodiesel, biomass-based diesel blends with more than 5 percent biomass-based diesel, and biodiesel blends with more than 5 percent biodiesel, a disclosure of the biomass-based diesel or biodiesel component, expressed as the percentage by volume. ATCP 94.120(2)(d)(d) For ethanol flex fuels, a disclosure of the ethanol component, expressed as the percentage by volume and the text “Use Only in Flex-Fuel Vehicles/May Harm Other Engines.” ATCP 94.120(3)(3) “Automotive gasoline” means a type of gasoline suitable for use in spark ignition automobile engines and also commonly used in marine and non-automotive applications. ATCP 94.120(4)(4) “Aviation gasoline” means a type of gasoline suitable for use as a fuel in an aviation spark- ignition internal combustion engine. ATCP 94.120(5)(5) “Aviation turbine fuel” means a refined middle distillate suitable for use as a fuel in an aviation gas turbine internal combustion engine. ATCP 94.120(6)(6) “Biodiesel blend” means a fuel comprised of biodiesel fuel with petroleum-based diesel fuel, designated BXX. In the abbreviation BXX, the XX represents the percent by volume of biodiesel fuel in the blend. ATCP 94.120(7)(7) “Biodiesel fuel” means a fuel comprised of at least 99 percent by volume mono-alkyl esters of long chain fatty acids derived from vegetable oils or animal fats, designated B100 or B99.
