Best Management Practices (BMPs)

• Avoid or minimize adverse effects to soil from erosion, sedimentations, and other pollutant delivery during road construction/reconstruction

• Use suitable measures in compliance with local direction to prevent and control invasive species

• Shape road surfaces to drain as designed

• Construct drainage control structures/features as need within the road prism

• Ensure culverts are clean and functioning

• Remove roadside berms unless specifically designed for erosion control measures

• Maintain the road surface drainage system to intercept.

o Clean ditches and catch basins only as needed to keep them functioning o So not undercut the toe of the cut slope when clearing ditches or catch basins.

• Do not undercut the toe of the cut slope when grading roads

• Do not permit side casting of maintenance-generated debris within a streamside management zone (SMZ)

• Avoid or minimize excavated materials entering waterbodies or riparian areas

• Utilize potential side cast or other waste on the road where applicable.

• Remove vegetation from Swales, ditches, shoulders, and cut/fill slopes only when it impedes adequate drainage, vehicle passage or obstructs necessary sight distances to avoid or minimize unnecessary or excessive vegetation disturbance.

• Design and locate parking and staging areas of appropriate size and configuration to accommodate expected vehicles and avoid minimize adverse effects to adjacent soil.

• Allow temporary re-fueling and servicing at approved locations, located well away from water or riparian zones.

• Use suitable measures around vehicle service, storage, and refueling areas, chemical storage and use areas, and waste dump to fully contain spills and avoid or minimize soil contamination and seepage to groundwater.

• Use suitable measure to avoid spilling fuels, lubricants, cleaners and other chemicals during handling and transporting

• Prohibit excess chemicals or waste from being stored or accumulated in the project area

• Remove service residues, used oil, and other hazardous and undesirable materials from the NFS land and properly dispose of them following completion of the project.

• Report spills and initiate suitable clean up actions in accordance with applicable state and federal laws, rules, and regulations.
