Public involvement.

§ 212.52 Public involvement. (a) General. The public shall be allowed to participate in the designation of National Forest System roads, National Forest System trails, and areas on National Forest System lands and revising those designations pursuant to this subpart. Advance notice shall be given to allow for public comment, consistent with agency procedures under the National Environmental Policy Act, on proposed designations and revisions. Public notice with no further public involvement is sufficient if a National Forest or Ranger District has made previous administrative decisions, under other authorities and including public involvement, which restrict motor vehicle use over the entire National Forest or Ranger District to designated routes and areas, and no change is proposed to these previous decisions and designations. (b) Absence of public involvement in temporary, emergency closures —(1) General. Nothing in this section shall alter or limit the authority to implement temporary, emergency closures pursuant to 36 CFR part 261, subpart B, without advance public notice to provide short-term resource protection or to protect public health and safety. (2) Temporary, emergency closures based on a determination of considerable adverse effects. If the responsible official determines that motor vehicle use on a National Forest System road or National Forest System trail or in an area on National Forest System lands is directly causing or will directly cause considerable adverse effects on public safety or soil, vegetation, wildlife, wildlife habitat, or cultural resources associated with that road, trail, or area, the responsible official shall immediately close that road, trail, or area to motor vehicle use until the official determines that such adverse effects have been mitigated or eliminated and that measures have been implemented to prevent future recurrence. The responsible official shall provide public notice of the closure pursuant to 36 CFR 261.51, including reasons for the closure and the estimated duration of the closure, as soon as practicable following the closure.
