“Alternative fuels.” Motor vehicle fuels and fuel systems which when compared to conventional gasoline or reformulated gasoline, diesel fuel, oil or coal will result in lower emissions of oxides of nitrogen, volatile organic compounds, carbon monoxide or particulates, toxic air pollutants, greenhouse gases or any combination thereof. These shall include, but are not limited to, compressed natural gas (CNG), liquefied natural gas (LNG), liquid propane gas (LPG), alcohols (ethanol - e85 and methanol - m85), hydrogen, hythane (any combination of CNG and hydrogen), biofuels and electricity.

“American Society for Testing and Materials International.” The nonprofit organization which develops consensus standards for materials, products, systems and services.

“Bi-fuel vehicle” or “dual-fuel vehicle.” A vehicle that operates on an alternative fuel and gasoline or an alternative fuel and diesel fuel. This term includes original equipment manufacturer (OEM) and retrofitted vehicles.

“Biodiesel fuel.” Either of the following:

“Biofuels.” Fuels derived from alcohols, ether, esters and other chemicals made from cellulosic biomass such as herbaceous and woody plants, agricultural and forestry residues and a large portion of municipal solid and industrial waste.

“Biomass-based diesel.” The term shall have the meaning set forth in section 211(o)(1)(D) of the Clean Air Act (69 Stat. 322, 121 Stat. 1519, 42 U.S.C. § 7545(o)(1)(D)) and shall meet the ASTM Specification D6751 Standard Specification for Biodiesel Fuel Blend Stock (B100) for Middle Distillate Fuels or its successor standard.

“Department.” The Department of Environmental Protection of the Commonwealth.

“Diesel fuel.” Diesel engine fuel and all other liquids suitable for the generation of power for the propulsion of motor vehicles except gasoline.

“Fleet.” A group of ten or more vehicles, comprised of passenger cars, light-duty trucks, buses and heavy-duty trucks up to 26,000 pounds gross vehicle weight that is owned and operated by a single school district, municipal authority, political subdivision, nonprofit entity, corporation, limited liability company or partnership located within this Commonwealth.

“Fund.” The Alternative Fuels Incentive Fund established under section 3.¹

“Gallon.” The quantity of fluid or liquid at a temperature of 60 degrees Fahrenheit necessary to completely fill a United States standard gallon liquid measure.

“Gasoline.” The same as a motor fuel and also means every liquid petroleum product, or combination thereof, other than solvents having an Atmospheric Pressure Index gravity of 46 degrees or above at a temperature of 60 degrees Fahrenheit and at atmospheric pressure and includes drip, casing head or natural gasoline. The term includes liquid of less than 46 degrees Atmospheric Pressure Index gravity at a temperature of 60 degrees Fahrenheit compounded, blended, manufactured or otherwise produced by mixing or blending gasoline or solvents with blending materials when the blended product can be used for generating power in internal combustion engines.

“Hybrid vehicle.” A motor vehicle that draws propulsion energy from onboard sources of stored energy that are both:

“Incremental cost.” Either of the following:

“OEM.” The original equipment manufacturer.

“OEM vehicle.” A vehicle originally manufactured to run on an alternative fuel.

“Qualified biomass-based diesel producer.” A producer of 25,000 gallons or more of biomass-based diesel per month with its principal production facility in this Commonwealth that has complied with the requirements of section 3.1(a)(2)² and that is in compliance with all laws and current in all obligations to the Commonwealth.

“Renewable energy.” Energy derived from solar, wind, geothermal and hydroelectric sources.

“Retrofit.” Install an alternative fuel system into a gasoline-fueled vehicle.

“Stationary power facility.” A fixed, in-place facility that generates electric power for distribution into the electric distribution system or for use onsite as primary power or backup power for critical need or at adjacent locations not connected to the electricity grid for primary power.
