Natural Gas Laws and Incentives in Wyoming

The list below contains summaries of all Wyoming laws and incentives related to natural gas.

Laws and Regulations

Alternative Fuel Definition

Alternative fuels are defined as pure methanol, ethanol and other blends of at least 85% alcohol, natural gas, propane, coal-derived liquid fuels, hydrogen, electricity, pure biodiesel, renewable diesel, fuels other than alcohol that are derived from biological materials, and P-series fuels. Biodiesel is defined as mono-alkyl esters of long chain fatty acids derived from vegetable oils or animal fats that meets current ASTM biodiesel standards. (Reference Wyoming Statutes 39-17-301)

Alternative Fuel License Fee

Each alternative fuel supplier, refiner, distributor, terminal operator, importer or exporter of alternative fuel used in motor vehicles must obtain an annual license from the Wyoming Department of Transportation to conduct business in the state. The fee for each type of license is $25. (Reference Wyoming Statute 39-17-306)

Alternative Fuel Tax Rate

A license tax of $0.24 per gasoline gallon equivalent (GGE) or diesel gallon equivalent (DGE) is collected on all alternative fuel used, sold, or distributed for sale or use in Wyoming. Alternative fuels include compressed natural gas (CNG), liquefied natural gas (LNG), propane, electricity, and renewable diesel. For taxation purposes, one GGE of CNG is equal to 5.66 pounds (lbs.), one DGE of LNG is equal to 6.06 lbs., one GGE of propane is equal to 1.35 gallons, and one GGE of electricity is equal to 33.56 kilowatt-hours. For more information, refer to the Wyoming Department of Transportation Tax Rates website. (Reference Wyoming Statutes 39-17-104, 39-17-204, 39-17-301. 39-17-303, and 39-17-304)

Compressed Natural Gas (CNG) Deregulation

A non-utility business that sells CNG for use as a motor vehicle fuel is not regulated as a public utility. (Reference Wyoming Statutes 37-1-101)

State Incentives

Alternative Fuel Export Tax Exemption

Alternative fuel sold for use in motor vehicles and intended for export from the state by a licensed alternative fuel exporter is exempt from the alternative fuel license tax. Any person exporting alternative fuel for which the license tax has been paid is eligible for a refund of the license tax paid. The exporter must submit the refund request within one year of the date of fuel purchase. (Reference Wyoming Statutes 39-17-301, 39-17-305, and 39-17-309(c))

Diesel Emission Reduction Project Funding

The Wyoming Department of Environmental Quality (DEQ) offers grants for nitrogen oxide emissions reduction projects. Funding is for heavy-duty on-road new diesel or alternative fuel repowers and replacements, as well as off-road repowers and replacements. Both government and non-government entities are eligible for funding. Vehicles that qualify for replacement or repower include:

  • Model Year (MY) 1992-2009 Class 8 local freight trucks and port drayage trucks;
  • MY 1992-2009 Class 4-7 local freight trucks;
  • MY 2009 or older Class 4-8 school buses, shuttle buses, and transit buses;
  • Airport ground support equipment;
  • Light-duty zero emission vehicle supply equipment; and
  • Diesel Emission Reduction Act projects.
This grant program is funded by Wyoming's portion of the Volkswagen Environmental Mitigation Trust. For more information, including how to apply, see the Wyoming DEQ’S Volkswagen Settlement website.

Natural Gas Infrastructure Loans

The Wyoming Business Council (Council) can issue loans to businesses for the cost of the engineering, design, real property, equipment, and labor necessary to install a natural gas fueling station. The loan may cover 75% of the total project cost, up to $1 million. Businesses receiving a loan do not have to pay interest or principal payments for the first two years of the loan term. When considering loan applications, the Council will consider existing fueling infrastructure and the volume of private and government fleet vehicles in the geographic area. For more information on loan requirements and applications, see the Council's Loan Programs website. (Reference Wyoming Statutes 9-12-301 through 9-12-304)
