Minn. Stat. § 239.77
Subd. 1. Biodiesel blend and fuel.
Subd. 2. Minimum content.
(a) Except as otherwise provided in this section, all diesel fuel sold or offered for sale in Minnesota for use in internal combustion engines must contain at least the stated percentage of biodiesel fuel oil by volume on and after the following dates:
| (1) | September 29, 2005 | 2 percent | |
| (2) | May 1, 2009 | 5 percent | |
| (3) | May 1, 2012 | 10 percent | |
| (4) | May 1, 2018 | 20 percent |
Except as provided in this paragraph, the minimum content levels in clauses (3) and (4) are effective during the months of April, May, June, July, August, and September only and the minimum content for the remainder of the year is five percent. However, if the commissioners of agriculture, commerce, and pollution control determine, after consultation with the biodiesel task force and other technical experts, that an American Society for Testing and Materials specification or equivalent federal standard exists for the specified biodiesel blend level in those clauses that adequately addresses technical issues associated with Minnesota's cold weather and publish a notice in the State Register to that effect, the commissioners may allow the specified biodiesel blend level in those clauses to be effective year-round. In each year that the seasonal reduction to five percent is in effect, the minimum content level of diesel fuel sold or offered for sale in Minnesota from April 1 to April 14 may be less than the level required under clause (4), but not less than ten percent.
(b) The minimum content levels in paragraph (a), clauses (3) and (4), become effective on the date specified only if the commissioners of agriculture, commerce, and pollution control publish notice in the State Register and provide written notice to the chairs of the house of representatives and senate committees with jurisdiction over agriculture, commerce, and transportation policy and finance, at least 270 days prior to the date of each scheduled increase, that all of the following conditions have been met and the state is prepared to move to the next scheduled minimum content level:
(4) at least five percent of the amount of biodiesel necessary for that minimum content level will be produced from a biological resource other than an agricultural resource traditionally grown or raised in the state, including, but not limited to, algae cultivated for biofuels production, waste oils, and tallow.
The condition in clause (2) may be waived if the commissioner finds that, due to weather-related conditions, the necessary feed stock is unavailable.
The condition in clause (4) may be waived if the commissioners find that the use of these nontraditional feedstocks would be uneconomic under market conditions existing at the time notice is given under this paragraph.
Subd. 3. Exempt equipment.
(a) The minimum content requirements of subdivision 2 do not apply to fuel used in the following equipment:
Subd. 3a. Number 1 diesel fuel exempt.
The minimum content requirements of subdivision 2 do not apply to Number 1 diesel fuel.
Subd. 4. Disclosure.
Subd. 5.
