ATA Response To Needing Diesel Gallon Equivalent Standard for Natural Gas Dispensing


In comments submitted July 14 to the National Conference of Weights and Measures (NCWM), ATA expressed its support for establishing a diesel gallon equivalent (DGE) standard for both liquefied natural gas (LNG) and compressed natural gas (CNG) sold at truck fueling locations.

The NCWM,  a nonprofit association of state and local weights and measures officials, federal agencies, manufacturers, retailers and consumers, works closely with the Department of Commerce’s National Institute of Standards and Technology.  The NCWM is meeting this week in Detroit, Michigan and is scheduled to vote on this matter.

In 1994, the NCWM developed a standard for CNG to be sold in gasoline gallon equivalents (GGE).  That standard has benefited consumers and industry alike because it provides a common unit for comparing the cost of CNG and gasoline.  The new DGE standard being proposed is needed because current rules do not address LNG and both CNG and LNG are increasingly being used in trucking applications displacing diesel fuel.

The DGE standard would allow for the ready comparison of CNG and LNG with diesel fuel and provide a common-sense unit of sale for fuel retailers and users.  In addition, the DGE standard would provide a benchmark for states in their taxation, accounting, and recordkeeping requirements.  ATA’s comments can be viewed here.  For more information contact Glen Kedzie at
