A. The Department of Labor shall adopt rules and procedures requiring that retail sales to the public of compressed natural gas and liquefied natural gas used as a motor vehicle fuel are dispensed in the following manner:

1. Compressed natural gas (CNG) shall be dispensed in gasoline gallon equivalent (GGE) units. A GGE of CNG shall initially be set at 5.66 (five and sixty-six hundredths) pounds and shall remain at that level until changed by the Department through the administrative rules process; and

2. Liquefied natural gas (LNG) shall be dispensed in diesel gallon equivalent (DGE) units. A DGE of LNG shall initially be set at 6.06 (six and six-hundredths) pounds and shall remain at this level until changed by the Department through the administrative rules process.

B. The Department of Labor is hereby authorized and directed to promulgate rules as may be necessary to carry out the provisions of this section. If it subsequently becomes necessary to revise, through rule, the standards established in paragraphs 1 and 2 of subsection A of this section due to changes in the energy contents of motor fuels, the Department shall take into consideration whether the National Conference on Weights and Measures has adopted similar standards for dispensing CNG and LNG and whether those standards use different values for GGE and DGE units. If the National Conference on Weights and Measures has adopted different GGE and DGE units, it shall be presumed that such standards should also be adopted for Oklahoma unless good cause is shown otherwise.
