Increases Minnesota's minimum biofuel content requirement from 10 percent to 15 percent conventional or advanced biofuel by volume, effective July 1, 2023, or 180 days after federal approval for year-round 15 percent biofuel sales, whichever is later.

Adjusts the acceptable biofuel blend range for compliance from 9.2-10.0 percent to 13.8-15 percent by volume and requires fuel dispensers to be labeled according to federal regulations.

Reduces the minimum conventional biofuel requirement percentage over time, reaching zero minimum on January 1, 2025, allowing increased use of advanced biofuels.

Creates two new exemptions: one allowing retailers to provide one dispenser with 9.2-10 percent biofuel for pre-2000 vehicles, and another exempting sellers of less than 500,000 gallons annually from equipment upgrade requirements until July 1, 2027.

Repeals the federal waiver conditions subdivision and updates reporting requirements to track intermediate biofuel blends (10-50 percent biofuel content) sold at retail.
