Attachment 5-SL-DB DUST ABATEMENT MAP.pdf

This document is a map illustrating the SCNF Annual Dust Abatement project for Stanley-Landmark and Dagger-Boundary Roads under the U.S. Department of Agriculture Forest Service. The map identifies two primary road sections requiring dust abatement treatment: the JCT NFSR 40579/40568 section spanning from NFSR 40568 MP 0.0 to NFSR 40579 MP 9.5, and the Camptender Trailhead section on NFSR 40568 MP 3.7. Both road segments require application of 0.5 gallons per square yard of magnesium chloride (MgCL2) with a 31% minimum concentration and 16-foot typical width application.

The map designates sensitive water crossings marked with red X symbols where product application is prohibited within 50 feet of water to be flagged by the Corps of Engineers. The road sections for product application are highlighted in orange throughout the mapped area of the Salmon-Challis National Forest in Idaho. The project location is approximately 21 miles from JCT 40579 on Stanley-Landmark Road, with the work prepared by Steffan Wilcox, Civil Engineer, as of January 22, 2026.
