Oregon Revised Statutes Protection from Fire § 477.670

During a fire season inside or within one-eighth of one mile of a forest protection district situated west of the summit of the Cascade Mountains, if the forestland in such district, or any part thereof, is susceptible in the judgment of the forester to damage by fire, the forester shall issue notice to that effect. Thereafter the use of fire in any form by any person in any operation area or the use of power-driven machinery for any operation, is unlawful unless approved by the forester. Approval shall be granted only when in the judgment of the forester the activity will not constitute a fire hazard sufficient to justify the requirement.
