Minn. Stat. § 161.465: REIMBURSEMENT FOR FIRE SERVICES.

(a) Ordinary expenses incurred by a municipal or volunteer fire department in extinguishing a grass fire within the right-of-way of a trunk highway must be reimbursed upon certification to the commissioner of transportation from the trunk highway fund. In addition, ordinary expenses incurred by a municipal or volunteer fire department in extinguishing a fire outside the right-of-way of any trunk highway if the fire originated within the right-of-way, upon approval of a police officer or an officer or employee of the Department of Public Safety must, upon certification to the commissioner of transportation by the proper official of the municipality or fire department within 60 days after the completion of the service, be reimbursed to the municipality or fire department from funds in the trunk highway fund. The commissioner of transportation shall take action practicable to secure reimbursement to the trunk highway fund of money expended under this section from the person, firm, or corporation responsible for the fire or danger of fire.

(b) The provisions of this section shall not be construed to admit state liability for damage or destruction to private property or for injury to persons resulting from a fire originating within a trunk highway right-of-way.
