Oregon Revised Statutes Protection from Fire § 477.665

(1) During a fire season inside or within one-eighth of one mile of a forest protection district, every operator using power-driven machinery in an operation area shall provide fire watch service on the operation area. The fire watch service shall consist of not less than one competent person, who shall be constantly on duty at times prescribed by rules promulgated by the State Forester. These rules shall require fire watch service at such times and at such places as the spread of fire on or from the operation area to forestland reasonably may be expected.

(2) The forester may modify or waive, in writing, any requirement of this section as to any operation whenever the fire hazard is not sufficient to justify the requirement.
