1 <br /> Maintenance • Catch basin filters should be inspected frequently,especially after <br /> Standards storm events. If the insert becomes clogged, it should be cleaned or <br /> replaced. <br /> • For systems using stone filters: If the stone filter becomes clogged <br /> with sediment,the stones must be pulled away from the inlet and <br /> cleaned or replaced. Since cleaning of gravel at a construction site <br /> may be difficult,an alternative approach would be to use the clogged <br /> stone as fill and put fresh stone around the inlet. <br /> • Do not wash sediment into storm drains while cleaning. Spread all <br /> excavated material evenly over the surrounding land area or stockpile <br /> and stabilize as appropriate. <br /> 1 <br /> 1 <br /> 1 <br /> 1 <br /> I <br /> 1 <br /> I <br /> 1 <br /> I <br /> 1 <br /> I <br /> 4-86 Volume 11-Construction Stormwater Pollution Prevention February 2005 <br />
