<br />BMP: SANDING PROCEDURES <br />1. METHODS: Wintertime sanding during storms is a necessity for <br />roads and driveways in the upper Clear Creek watershed. Since road sand <br />typically contains some percentage of salt (5 to 20%), snow melt can have <br />negative effects on water quality. Recommended methods include: <br />? Use the minimum amount of sand needed to accomplish the job. <br />? Use the lowest feasible content of salt. <br />? Sweep sand from paved roads as soon as possible following storm. <br />? Recycle sand if feasible. <br />? Store sand on lined, curbed or bermed site and under shelter if <br />possible. <br />2. MATERIALS: Sand with salt. Alternate materials to reduce fugitive <br />dust and reduce the need for salt are being evaluated by various <br />municipalities and the Department of Transportation. Contact CDOT for <br />more information. <br />3. MAINTENANCE: Sand should be removed from paved streets as soon as <br />feasible following storm. <br />4. TEMPORARY OR PERMANENT USE: This is a permanent BMP. <br />22 <br />
