(a) Except as provided in subdivisions 10 to 14, a person responsible for the product shall ensure that all gasoline sold or offered for sale in Minnesota must contain at least the quantity of biofuel required by clause (1) or (2), at the option of the person responsible for the product:
(1) the greater of:
(i) 10.0 percent conventional biofuel by volume; or
(ii) the maximum percent of conventional biofuel by volume authorized in a waiver granted by the United States Environmental Protection Agency; or
(2) 10.0 percent of a biofuel, other than a conventional biofuel, by volume authorized in a waiver granted by the United States Environmental Protection Agency or a biofuel formulation registered by the United States Environmental Protection Agency under United States Code, title 42, section 7545.
(b) For purposes of enforcing the requirement of paragraph (a), clause (1), item (i), a gasoline/biofuel blend will be construed to be in compliance if the biofuel content, exclusive of denaturants and other permitted components, comprises not less than 9.2 percent by volume and not more than 10.0 percent by volume of the blend as determined by an appropriate United States Environmental Protection Agency or American Society of Testing Materials standard method of analysis.
(c) The aggregate amount of biofuel blended pursuant to this subdivision may be any biofuel; however, conventional biofuel must comprise no less than the portion specified on and after the specified dates:

Subd. 2a. Federal Clean Air Act waivers; conditions. (a) Before a waiver granted by the United States Environmental Protection Agency under United States Code, title 42, section 7545, may alter the minimum content level required by subdivision 1, paragraph (a), clause (1), item (ii), the waiver must:
(1) apply to all gasoline-powered motor vehicles irrespective of model year; and

(b) The minimum biofuel requirement in subdivision 1, paragraph (a), clause (1), item (ii), shall, upon the grant of the federal waiver, be effective the day after the commissioner of commerce publishes notice in the State Register. In making this determination, the commissioner shall consider the amount of time required by refiners, retailers, pipeline and distribution terminal companies, and other fuel suppliers, acting expeditiously, to make the operational and logistical changes required to supply fuel in compliance with the minimum biofuel requirement.
Subd. 2b. Limited liability waiver. No motor fuel shall be deemed to be a defective product by virtue of the fact that the motor fuel is formulated or blended pursuant to the requirements of subdivision 1, paragraph (a), clause (1), item (ii), under any theory of liability except for simple or willful negligence or fraud. This subdivision does not preclude an action for negligent, fraudulent, or willful acts. This subdivision does not affect a person whose liability arises under chapter 115, water pollution control; 115A, waste management; 115B, environmental response and liability; 115C, leaking underground storage tanks; or 299J, pipeline safety; under public nuisance law for damage to the environment or the public health; under any other environmental or public health law; or under any environmental or public health ordinance or program of a municipality as defined in section 466.01.
Subd. 2c. Fuel dispensing equipment; blends over ten percent ethanol. Notwithstanding any other law or rule, fuel dispensing equipment authorized to dispense fuel under subdivision 1, paragraph (a), clause (1), is authorized to dispense fuel under subdivision 1, paragraph (a), clause (2), or subdivision 1a.
Subd. 3. Blending restriction. When gasoline contains an oxygenate, a person responsible for the product shall not blend the product with ethanol or with any other oxygenate after it is transferred or otherwise removed from a refinery or terminal.

Subd. 7. Ethanol records; state audit. The director shall audit the records of registered ethanol blenders to ensure that each blender has met all requirements in this chapter. Specific information or data relating to sales figures or to processes or methods of production unique to the blender or that would tend to adversely affect the competitive position of the blender must be only for the confidential use of the director, unless otherwise specifically authorized by the registered blender.
Subd. 8. Disclosure. (a) A refinery or terminal, shall provide, at the time gasoline is sold or transferred from the refinery or terminal, a bill of lading or shipping manifest to the person who receives the gasoline. For oxygenated gasoline, the bill of lading or shipping manifest must include the identity and the volume percentage or gallons of oxygenate included in the gasoline, and it must state: "This fuel contains an oxygenate. Do not blend this fuel with ethanol or with any other oxygenate." For nonoxygenated gasoline sold or transferred after September 30, 1997, the bill or manifest must state: "This fuel is not oxygenated. It must not be sold at retail in Minnesota." This subdivision does not apply to sales or transfers of gasoline between refineries, between terminals, or between a refinery and a terminal.
