Does not stockpile in or near storm drains or watercourses. <br />7. Place bagged materials on pallets and under cover. <br />8. While activities associated with the BMP are under way, inspect weekly during the rainy <br />season and at two-week intervals in the non-rainy season to verify continued BMP <br />implementation. <br />9. Repair and/or replace perimeter controls and covers as needed to keep them <br />functioning properly. <br /> Vehicle Fueling, Washing and Maintenance <br />Activities associated with fueling and cleaning of municipal vehicles and equipment can easily <br />contribute pollutants to stormwater discharges or directly discharge to the municipal <br />separate storm sewer (MS4). Spills and leaks that occur during vehicle and equipment fueling <br />can contribute hydrocarbons, oils, grease, metals, and other toxic chemicals to stormwater <br />run-off or discharge directly into storm sewers or receiving waters. Pollutants from washing <br />and maintaining vehicles can vary from engine oil to chemicals within detergents such as <br />phosphates. Properly designed and constructed fueling and wash areas will reduce the <br />potential for contaminated discharges. <br />The ideal location for washing vehicles is at a commercial vehicle wash. Commercial vehicle <br />washes can recycle their water on-site as well as contain the it so it will not enter the storm <br />drain. If no commercial vehicle washes are available, then vehicles should be washed indoors <br />(that will drain to sanitary sewers) or on grass/pervious surfaces. <br />1. General fueling practices: <br />a) Place drip pans or absorbent pads under direct fueling location if fueling will occur <br />over a permeable surface. <br />b) Do not "top off" fuel tanks. <br />c) Do not place used spill response materials in adjacent trash receptacles. Dispose <br />in a proper manner. <br />d) Do not leave active fueling operations unattended. <br />2. General washing practices: <br />a) Keep equipment clean; do not allow a buildup of oil/grease. <br />b) Place spill clean-up materials in readily available locations by the wash area <br />(clearly mark location of spill clean-up materials). <br />c) Clean up spills or any wash water that may improperly discharge and <br />contaminate. <br />d) Consider using phosphate-free detergents. <br />e) The optimal location for a wash area is indoors where connection to the sanitary <br />sewer is more easily achieved and exposure to rain events is eliminated. <br />f) Do not store solvents or degreasers in the wash area. <br />3. General maintenance practices: <br />a) Keep all wash areas neat and orderly. <br />b) Perform monthly inspections and clean and maintain any sumps or oil/water <br />separators installed at the wash area.
