(b) After gasoline is sold, transferred, or otherwise removed from a refinery or terminal, a person responsible for the product:
(1) may blend the gasoline with agriculturally derived ethanol as provided in subdivision 4;
(2) shall not blend the gasoline with any oxygenate other than biofuel;
(3) shall not blend the gasoline with other petroleum products that are not gasoline or biofuel;
(4) shall not blend the gasoline with products commonly and commercially known as casinghead gasoline, absorption gasoline, condensation gasoline, drip gasoline, or natural gasoline; and
(5) may blend the gasoline with a detergent additive, an antiknock additive, or an additive designed to replace tetra-ethyl lead, that is registered by the EPA.
Subd. 4. Gasoline blended with ethanol; general. (a) Gasoline may be blended with agriculturally derived, denatured ethanol that complies with the requirements of subdivision 5.
(b) A gasoline-ethanol blend must:
(1) comply with the volatility requirements in Code of Federal Regulations, title 40, part 1090;
(2) comply with ASTM specification D4814-11b, or the gasoline base stock from which a gasoline-ethanol blend was produced must comply with ASTM specification D4814-11b; and
(3) not be blended with casinghead gasoline, absorption gasoline, condensation gasoline, drip gasoline, or natural gasoline after the gasoline-ethanol blend has been sold, transferred, or otherwise removed from a refinery or terminal.
Subd. 4a. Gasoline blended with ethanol; standard combustion engines. Gasoline combined with ethanol for use in standard combustion engines may be blended with up to ten percent agriculturally derived, denatured ethanol, by volume, or any percentage specifically authorized in a waiver granted by the United States Environmental Protection Agency under section 211(f)(4) of the Clean Air Act, United States Code, title 42, section 7545, subsection (f), paragraph (4). The gasoline-ethanol blend must comply with the general provisions in subdivision 4.
Subd. 4b. Gasoline blended with ethanol; alternative fuel vehicles. (a) Gasoline blended for use in an alternative fuel vehicle, as defined in section 296A.01, subdivision 5, may contain any percentage of agriculturally derived, denatured ethanol, by volume, not to exceed 85 percent. The gasoline-ethanol blend must comply with the general provisions in subdivision 4. The gasoline and ethanol may be blended by an ethanol blender or at the point of retail sale in an ethanol-blending fuel dispenser clearly labeled "FLEX-FUEL VEHICLES ONLY." If blended by an ethanol blender, the percentage of ethanol in the resulting gasoline-ethanol blend must be clearly identified.
(b) If a person responsible for the product utilizes an ethanol-blending fuel dispenser to dispense both gasoline blended with ethanol for use in alternative fuel vehicles and gasoline blended with ethanol for use in standard combustion engines, the person must ensure that the gasoline blended with ethanol for use in standard combustion engines is dispensed from a fuel-dispensing hose and nozzle or other conveyance dedicated solely to gasoline blended with ethanol for use in standard combustion engines and clearly labeled as such.
(c) A person responsible for the product who complies with the provisions in paragraph (b) is not responsible for a self-service fueling action taken by that person's retail fuel customer.
Subd. 5. Denatured ethanol. Denatured ethanol that is to be blended with gasoline must be agriculturally derived and must comply with ASTM specification D4806-11a. This includes the requirement that ethanol may be denatured only as specified in Code of Federal Regulations, title 27, parts 20 and 21.
