IL SB1907

Amends the Motor Fuel Tax Law to define measurement standards for alternative fuels: liquefied natural gas (LNG) and propane taxed at diesel gallon equivalents (6.06 pounds of LNG or 6.41 pounds of propane), and compressed natural gas taxed at gasoline gallon equivalents (5.660 pounds).

Establishes tax rate on compressed natural gas at 19 cents per gallon beginning January 1, 1990, calculated on a gasoline gallon equivalent basis.

Expands the definition of taxable motor fuels to include liquefied natural gas and propane, with diesel fuel and these alternative fuels subject to an additional 2.5 cents per gallon tax.

Excludes liquefied natural gas from certain reporting requirements for fuel distributors unless the fuel is dispensed directly into motor vehicle tanks or delivered to accessible storage facilities for vehicle refueling.

Amends the Weights and Measures Act and Environmental Impact Fee Law to incorporate diesel gallon equivalent and gasoline gallon equivalent definitions for alternative fuel sales and taxation purposes.
