South Dakota E85 Laws and Incentives


State Incentives

Ethanol Production Incentive

A $0.20 per gallon production incentive is available to ethanol producers for ethanol that is fully distilled and produced in South Dakota. To be eligible for this incentive, the ethanol must be denatured and blended with gasoline to create an ethanol blend. Cumulative annual production incentives paid out may not exceed $7 million. (Reference South Dakota Statutes 10-47B-162)

State Laws and Regulations

Ethanol Blends Promotion

The South Dakota Legislature urges the U.S. Environmental Protection Agency and other appropriate federal agencies to authorize the use of ethanol blends higher than 10% in non-flexible fuel vehicles. (Reference Senate Concurrent Resolution 11, 2009)

Biofuels Promotion

The South Dakota Legislature supports a "25 x 25" vision in which agricultural products will provide 25% of the total energy consumed in the United States by the year 2025. Biodiesel and ethanol will be used to meet this goal. (Reference House Concurrent Resolution 1010, 2008)

Regional Biofuels Promotion Plan

South Dakota has joined Indiana, Iowa, Kansas, Michigan, Minnesota, Ohio, and Wisconsin in adopting the Energy Security and Climate Stewardship Platform Plan (Platform) (PDF 2 MB), which establishes shared goals for the Midwest region, including increased biofuels production and use. Specifically, the Platform sets the following goals:

  • Produce commercially available cellulosic ethanol and other low-carbon fuels in the region by 2012;
  • Increase E85 availability at retail fueling stations in the region to 15% of stations by 2015, 20% by 2020, and 33% of all fueling stations in the region by 2025;
  • Reduce the amount of fossil fuel that is used in the production of biofuels by 50% by 2025;
  • By 2025, at least 50% of all transportation fuels consumed by the Midwest will be from regionally produced biofuels and other low-carbon transportation fuels.

The Platform also establishes a regional biofuels corridor program. The program directs state transportation, agriculture, and regulatory officials to develop a system of coordinated signage across the region for biofuels and advanced transportation fuels and to collaborate to create regional E85 corridors. The program requires standardized fuel product coding at fueling stations as well as increased education for retailers about converting existing fueling infrastructure to dispense E85.

Biofuels Economic Development Plan

The South Dakota Legislature has resolved to develop a biofuels economy in the state by investing in the development of perennial biomass crops, including switchgrass and other native grasses by supporting long-term research and development of crops and cropping systems; and providing opportunities to purchase biofuels by promoting the development of vehicles that operate on biofuels, expanding the government purchase of biofuels, and offering incentives for fueling stations offering blends of biofuels such as E85 and B20. (Reference Senate Concurrent Resolution 8, 2007)

Ethanol Production Facility Fee

A fee of $1,000 is required with the submittal of an air quality permit application for an ethanol production plant. In addition, there is an annual renewal fee required for the duration of the air quality permit. The annual renewal fee includes an administrative fee of $1,000 and an emissions fee equaling $40 per ton particulate matter, sulfur dioxide, nitrogen oxide, volatile organic compounds, and hazardous air pollutants emitted by the ethanol production plant during the previous calendar year. The annual fee must be paid to the South Dakota Department of Revenue and Regulation by July 31 following the year in which the permit is issued and annually thereafter. (Reference South Dakota Statutes 34A-1)

Fuel Quality Standards

The Secretary of the South Dakota Department of Public Safety may promulgate rules establishing the following: 1) standards for the maximum volume percentages of ethanol and methanol in alcohol blended fuels; 2) a program for the inspection and testing of alcohol blended fuels, petroleum products, biodiesel, and biodiesel blends and prescribing the methods to be used; 3) labeling requirements for devices dispensing alcohol blended fuels, biodiesel, and biodiesel blends; 4) standards setting the specifications and tolerance requirements for petroleum products, biodiesel, and biodiesel blends; and 5) regulations for filtering systems used on devices dispensing alcohol blended fuels. All rules must conform to appropriate ASTM standards. (Reference South Dakota Statutes 37-2-6)

Ethanol Blend Definition

An ethanol blend is defined as a blended motor fuel containing ethyl alcohol that is at least 99% pure and derived from agricultural products, which is blended exclusively with gasoline. (Reference Senate Bill 21, 2009, and South Dakota Statutes 10-47B-3)

Ethanol and Methanol Fuel Tax

Ethyl alcohol and methyl alcohol motor fuels are taxed at a rate of $0.08 per gallon when used as a motor fuel. Ethyl alcohol is defined as a motor fuel that is typically derived from agricultural products that have been denatured. Methyl alcohol is a motor fuel that is most commonly derived from wood products. (Reference Senate Bill 21, 2009, and South Dakota Statutes 10-47B-3 and 10-47B-4)
