Mo. Rev. Stat. § 70.322: Road equipment, public entity, cemetery or nonprofit organization may contract to use certain political subdivision's equipment, requirements — costs.

A public entity, cemetery or nonprofit organization may contract with any county, city, township, or any special road district for the use of such county's, city's, township's or special road district's equipment and personnel to repair or maintain roads of public entities, cemeteries or roads owned by nonprofit organizations, or to perform such other roadwork-related activities for such public entity, cemetery or nonprofit organization, if such public entity, cemetery or nonprofit organization is located within the boundaries of the county, city, township, or special road district. As used in this section, a nonprofit organization shall mean a 501(c)(3) organization as defined under the Internal Revenue Code and an organization in an area where there is no access to private services. Such contract shall be in writing and shall provide that:

(1) The public entity, cemetery or nonprofit organization holds the county, city, township, or special road district harmless for any damage to persons or property which may accrue as a result of such roadwork; and

(2) The public entity, cemetery or nonprofit organization shall pay the county, city, township, or special road district for such roadwork. The amount of payment shall be stated in the contract, and shall not be less than the reasonable cost to the county, city, township, or special road district for such roadwork or rental.
