Laws and Regulations
Renewable Fuel Distributor and Vehicle Manufacturer Liability Protection
Renewable fuel refiners, suppliers, terminals, wholesalers, distributors, retailers, and motor vehicle manufacturers and dealers are not liable for property damages related to a customer's purchase of renewable fuel, including blends, if the consumer selected the fuel for use. Motor fuel blended with any amount of renewable fuel will not be considered a defective product provided the fuel compiles with motor fuel quality regulations. (Reference Missouri Revised Statutes 414.255)
State Energy Plan
The Missouri Department of Economic Development's Division of Energy developed a comprehensive state energy plan to include information related to alternative fuels and advanced vehicles, as well as electric generation, fuels and resource extraction, energy distribution, energy usage, energy storage, energy-related land use issues, energy prices, energy security, and emergency resource planning. For more information, see the Missouri Energy Plan website. (Reference Executive Orders 15-02, 2015, and 14-06, 2014)
Ethanol Blend Mandate
All gasoline offered for sale at retail stations within the state must contain 10% ethanol (E10). This requirement is waived only if a distributor is unable to purchase ethanol or ethanol-blended gasoline at the same or lower price as unblended gasoline. Premium gasoline is exempt from this requirement. Ethanol is defined as fuel that is derived from an agricultural source and that meets ASTM specification D4806. (Reference Missouri Revised Statutes 414.255)
Alternative Fuel Tax
Compressed natural gas (CNG) used as a vehicle fuel is taxed on a gasoline gallon equivalent (GGE) basis as follows:
- $0.05 per GGE until December 31, 2019;
- $0.11 per GGE from January 1, 2020, until December 31, 2024; and
- $0.17 per GGE from January 1, 2025, and beyond.
- $0.05 per DGE until December 31, 2019;
- $0.11 per DGE from January 1, 2020, until December 31, 2024; and
- $0.17 per DGE from January 1, 2025, and beyond.
- $0.05 per gallon until December 31, 2019;
- $0.11 per gallon from January 1, 2020, until December 31, 2024; and
- $0.17 per gallon from January 1, 2025, and beyond.
Alternative Fuel Vehicle (AFV) Decal
The state motor fuel tax does not apply to passenger vehicles, certain buses, or commercial vehicles that are powered by an alternative fuel, if the vehicles obtain an AFV decal. Owners or operators of such vehicles that also own or operate a personal fueling station must pay an annual alternative fuel decal fee, as listed below. Alternative fuel motor vehicles licensed as historic vehicles are exempt from the alternative fuel decal requirement.
|Gross Vehicle Weight (GVW)||Type of Vehicle||Decal Fee|
|18,000 pounds (lbs.) or less||Passenger, School Bus, or Commercial||$75|
|18,001 lbs.-36,000 lbs.||Farm or Farming Transportation with an 'F' License Plate||$100|
|18,001 lbs.-36,000 lbs.||Passenger-Carrying and Other Motor Vehicles||$150|
|36,000 lbs. or more||Farm or Farming Transportation with an 'F' License Plate||$250|
|36,000 lbs. or more||All Other Motor Vehicles||$1,000|
Propane License Requirement
Any individual that transports, handles, or sells propane at retail, or is in the business of installing or modifying related equipment, must first register with the Missouri Department of Agriculture. (Reference Missouri Revised Statutes 323.060)
Low-Speed Vehicle Access to Roadways
A low-speed vehicle is defined as a four-wheeled vehicle with a maximum speed of 25 miles per hour (mph) that is manufactured in compliance with safety standards specified in Title 49 of the Code of Federal Regulations, section 571.500. A low-speed vehicle may not operate on a street or highway with a posted speed limit greater than 35 mph. (Reference Missouri Revised Statutes 304.029)
Biodiesel Use Requirement
At least 75% of the Missouri Department of Transportation (MoDOT) vehicles and heavy equipment that use diesel fuel must be fueled with biodiesel blends of at least 20% (B20), if such fuel is commercially available. The blended biodiesel fuel will be considered commercially available if the incremental purchase cost compared to conventional diesel fuel is not more than $0.25. To the maximum extent practicable, MoDOT may obtain funding for the incremental cost of the blended biodiesel fuel from the state's Biodiesel Fuel Revolving Fund. (Reference Missouri Revised Statutes 414.365 and 414.407)
Alternative Fuel Vehicle (AFV) Acquisition and Alternative Fuel Use Requirements
A state agency that operates a vehicle fleet consisting of 15 vehicles or more must ensure that at least 50% of new vehicles purchased over a defined biennial period are capable of operating using an alternative fuel. Excess acquisitions of AFVs may be credited towards future biennial goals. If a state agency fails to meet a biennial acquisition goal, purchases of any non-AFVs are not permitted until the goals are met or an exemption or goal reduction has been granted. In addition, 30% of the fuel purchased annually for use in operating state fleet vehicles must be alternative fuels. (Reference Missouri Revised Statutes 414.400 and 414.410)
Alternative Fuel Promotion
The Missouri Alternative Fuels Commission (Commission) promotes the continued production and use of alternative transportation fuels in Missouri. The Commission submits a report annually to the governor and general assembly and provides recommendations on changes to state law to facilitate the sale and distribution of alternative fuels and alternative fuel vehicles; promotes the development, sale, distribution, and consumption of alternative fuels; promotes the development and use of alternative fuel vehicles and technology that will enhance the use of alternative and renewable transportation fuels; educates consumers about alternative fuels; and develops a long-range plan for the state to reduce consumption of petroleum fuels. For more information, see the Missouri Alternative Fuels Commission page. (Reference Missouri Revised Statutes 414.420)
