    Note: For purposes of calculating tax under the Motor Fuel Tax Law, a gallon of compressed natural gas means a quantity of compressed natural gas equal to 126.67 cubic feet of natural gas at 60 degrees Fahrenheit and one atmosphere of pressure. In the alternative, it means a quantity of compressed natural gas that weighs 5.66 pounds.

(1) For LPG, “gallon” means diesel gallon equivalent (DGE), which is defined as 6.41 pounds of LPG.

(2) For LNG, “gallon” means DGE, which is defined as 6.06 pounds of LNG.

(3) For CNG, “gallon” means gasoline gallon equivalent (GGE), which is defined as 5.66 pounds of CNG.
