OAR 629-630-0925: Written Plans to Evaluate Harvesting on Features Identified in the Slopes Model

To evaluate timber harvesting on features identified by the slopes model, operators shall submit a written plan that describes how the operation is planned to be conducted in sufficient detail to allow the State Forester to evaluate and comment on the likelihood that the operation will comply with the Forest Practices Act or administrative rules. The written plan shall include at a minimum: (1) A unit map including, where applicable: (a) Locations of slopes model designated debris flow traversal areas; (b) Locations of slopes model designated sediment source areas and those selected as slope retention areas; and (c) Identification of approximate yarding corridors relative to (1)(a) and (b). (2) Description of the rationale and appropriate documentation for the following that apply: (a) Selection of the 50 percent designated debris flow traversal areas for Western Oregon forestlands that are managed under the small forestland owner minimum option; (b) Selection of slope retention areas, including justification for choosing areas to satisfy the minimum 50 percent designated sediment source area requirement, as described in OAR 629-630-0910(3) and (4); (c) How the number, size, and location of yarding corridors were designed to minimize impacts to the designated debris flow traversal areas; and (d) How the number, size, and location of yarding corridors were designed to minimize soil and vegetation disruptions that may increase slope instability in slope retention areas. (3) Additional administrative information related to the operation as required by individual rules or as requested by the State Forester.
