The Forestry Commission may negotiate agreements with Federal Agencies for providing fire, detection, presuppression, and suppression services on Federal lands. The charges for these services must be no less than the cost to the Commission for rendering the services. All receipts from services provided by the Commission must be used to offset the cost of providing the services. When the State Forester determines the assistance received from a federal agency on adjoining private or state lands equals that provided by the state on federal lands, no charges will be made.
