Attachment 2-SL-DB DUST ABATEMENT MAP.pdf

This document is a map depicting the SCNF Annual Dust Abatement project for Stanley-Landmark and Dagger-Boundary Roads administered by the U.S. Department of Agriculture Forest Service. The map identifies two primary road sections requiring dust abatement treatment: the Camptender Trailhead section (NFSR 40568 MP 3.7) and the JCT HWY21/NFSR 40579 section (NFSR 40579 MP 0.0), both located in Idaho near Stanley. The treatment specifications for both sections require application of 0.5 gallons per square yard of a 31% minimum magnesium chloride (MgCL2) product with a 16-foot typical width application.

The map uses color-coded sections to identify the orange-highlighted road segments designated for product application and marks sensitive water crossings with red X symbols that must be flagged by the Colorado Outfitters and Recreationists (COR) to prevent product contact with water sources. The Camptender Trailhead section extends from mile 3.7 on NFSR 40568, while the JCT HWY21/NFSR 40579 section begins at mile 0.0 and extends approximately 21 miles from the junction point. The document was prepared by Steffan Wilcox, Civil Engineer, on January 22, 2026, at a map scale of 1:150,000.
