Oregon Revised Statutes Protection from Fire § 477.615

(1) During a fire season inside or within one-eighth of one mile of a forest protection district, when, in the judgment of the forester, an operation is of sufficient size or so planned and operated as to justify additional protection from fire, the owner or operator, when so directed by the forester in writing, shall provide, within such time as is specified in the writing, additional water supply and equipment for use in fire suppression that is in conformity with rules promulgated by the State Forester.

(2) All such equipment shall be kept in constant readiness for instant use in fighting forest fires. However, nothing in this section prohibits the use of the equipment by the operator for sprinkling roads or other uses within the operation area.

(3) Rules promulgated under this section shall prescribe such water supply and equipment as reasonably are necessary to provide immediate and effective suppression of fires on forestland and may provide for the use of alternate methods and equipment.
