Minnesota has released a new Biodiesel Fire Code Variance Toolkit to help fleet operators navigate the process for using high-concentration B100 biodiesel. The initiative aims to support greenhouse gas reduction goals while addressing equipment compatibility for heavy-duty vehicles.
Why it matters
Current fire codes require fueling equipment to be certified by national laboratories, but these listings do not yet cover blends above 20% biodiesel. This toolkit provides the necessary path for operators to bypass that hurdle through formal site-specific variances.
The toolkit assists operators in navigating the variance process for B100 fuel, contrasting with the state's existing B20 mandate effective April through September. As a practical example, the City of Edina has already upfitted 10 heavy-duty assets to utilize this higher blend.
The players
Minnesota Department of Public Safety State Fire Marshal
The state agency responsible for fire prevention, building codes, and safety oversight of fuel-dispensing systems.
City of Edina
A Minnesota municipality that has demonstrated the transition by upfitting ten of its heavy-duty fleet vehicles.
The details
Under current Minnesota State Fire Code, all fuel-dispensing equipment must carry a listing from a nationally recognized testing laboratory. Because such certifications for B100 systems remain unavailable, operators must apply for a fire code variance. The new toolkit streamlines this by standardizing the submission of site plans, fuel specifications, and specific equipment technical details for review.
Timeline
The Minnesota Climate Action Framework was originally published in 2022.
The state's B20 blending mandate applies every year from April through September.
Legislators urged the EPA to expand fuel eligibility on October 15, 2026.
The toolkit was published on October 28, 2026.
The Home Front
The release of this toolkit marks a formal step in the implementation of the 2026 update to the Minnesota Climate Action Framework. It bridges the gap between state-level environmental mandates and the practical fire-safety regulations required for heavy-duty fuel infrastructure.
While this toolkit is designed for fleet operators, residents should note that fuel infrastructure standards for high-blend biodiesel are evolving to meet state climate goals. If you have questions about equipment safety or local fuel compliance, contact your local fire marshal for verified information.
The takeaway
Minnesota's new toolkit provides a clear, compliant path for utilizing B100 fuel where national certifications do not yet exist. Fleet operators should review the toolkit requirements to ensure all site plans and equipment specifications meet current state fire safety standards.
