Unless the entire project area is already infected with noxious weeds, the contractor shall ensure that prior to moving on to another part of the project area all off-road equipment, which last operated in areas known by Forest Service to be infected with noxious weeds, is free of soil, seeds, vegetative matter, or other debris that could contain or hold seeds.

A Current list of noxious weeds of concern to Forest Service is available at the Forest Supervisor’s office. Contractor shall clean off-road equipment prior to moving between project areas with known infestations with noxious weeds and other project areas, if any, which are free of such weeds. Project area maps show areas known by Forest Service that contain specific noxious weeds species of concern. Contractor shall employ whatever cleaning methods are necessary to ensure that off-road equipment is free of noxious weeds. Equipment shall be considered free of soil, seeds, and other such debris when a visual inspection does not disclose such material. Disassembly of equipment components or specialized inspection tools is not required. Contractor shall notify Forest Service at least 24 hours prior to beginning of work in area designated as a noxious weed area, unless otherwise agreed. Notification shall include the location of the equipment’s most recent operations.

Contractor or Forest Service, within the project area or on the haul route, shall be promptly reported to the other party.
