PS 92(10)

Quantity of Natural Gas Equivalent to Gallon of Gasoline for Motor Vehicle Fuels Tax Purposes

This publication has been superseded by PS 92(10.1)

BACKGROUND: For motor vehicle fuels tax purposes, "fuel" is defined by Conn. Gen. Stat. Section 12-455a(b) as meaning "(1) fuels as defined in section 14-1 and (2) any other combustible gas or liquid suitable for the generation of power to propel motor vehicles." While this definition includes natural gas and other fuels in a gaseous form, the Department has routinely provided information concerning the tax per gallon of gasoline, gasohol and diesel fuel, but not concerning the tax per equivalent quantity of fuels, such as natural gas, in a gaseous form.

PURPOSE: This Policy Statement provides information concerning the quantity of natural gas that is equivalent to a gallon of gasoline.  From this point on, it will be the policy of the Department to provide this information whenever tax rate information concerning gasoline, gasohol and diesel fuel is provided.  If the Department receives scientifically reliable information concerning other fuels in  a gaseous form, corresponding information will be provided.

STATUTORY AUTHORITY: Conn. Gen. Stat. Sections 12-455a(b).

EFFECTIVE DATE: This Policy Statement is effective upon issuance.

NATURAL GAS means naturally occurring mixtures of hydrocarbon gases and vapors consisting principally of methane, whether in gaseous or liquid form.
