ORS § 476.290
Whenever a fire is extinguished pursuant to ORS 476.280, the governing body of the city or the district board of the rural fire protection district that provided the fire suppression service may, on forms furnished by the Department of the State Fire Marshal for such purposes, bill the owner of the property involved in the fire for the cost of providing the fire suppression service. The governing body of the city or the district board of the rural fire protection district that provided the fire suppression service may determine the cost of providing the fire suppression service by use of a state standardized-costs schedule as approved by the State Fire Marshal. The cost charged for providing the fire suppression service may not be greater than the pro rata cost that would have been charged by the city or district for the performance by the city or district of a similar fire suppression service within its jurisdiction. If the cost is not paid within 30 days after the second billing, the governing body of the city or the district board of the rural fire protection district that provided the fire suppression service may bring an action for the recovery of the unpaid cost from the owner of the real property upon which the fire suppression service was rendered.
