11. Using the boom, crane, or tripod, loHer <br />and install the new cartridges. Once <br />again, take care r�ot to damage <br />connections. <br />12. Close and fasten the door. <br />13. Remove safety equipment. <br />i�l. Make notes about the local drainage <br />area relative to ongoing construction, <br />erosion problems, or nigh loadings of <br />other materials to the system. <br />15. Finally, dispose of the residual materials <br />in accordance with applicabie <br />reg��lations. Make arrangements to <br />retu�n the used cartridges to Stormw�ter <br />M anagement, Inc. <br />Related Maintenance Activities <br />(Performed on an as-needed basis) <br />StormFiller unils are often just one of many <br />components in a more comprehensive <br />stormwater drainage and treatment system. <br />The entire system may inctude catch <br />basins, deler.tion vaults, sedimentation <br />vaults and manholes, detention/retention <br />ponds, swales, artificial wetlands, and other <br />miscellaneous components. <br />In order for maintenance of the StormFilter <br />to be successful, it is imperative that ail <br />other components be properly maintained. <br />The maintenancelrepair oi upstream <br />facilities should be carried out prior to <br />SlormFilter maintenance activities. <br />In addition to considering upstream <br />facilities, it is also important to correct any <br />probiems identified in the drainage area. <br />Drainage area concerns may include: <br />erosion problems, heavy oil and grease <br />loading, and discharges of inappropriate <br />materials. <br />Material Disposal <br />The accumulated sediment fo�nd in <br />stormwater treatment and cenveyance <br />systems must be handled and diaposed of <br />in a manner that will not allow the material <br />to a(tect surface or ground water. It is <br />possible for sediments to contain <br />measurable concentrations of heavy n�etals <br />and organic chemicals (such as pesticides <br />and petroleum products). Areas with the <br />greatest potential for high pollutant loading <br />i�clude industrial areas and heavily traveled <br />roads. <br />Sediments and water must be disposed o( <br />in accordance with all applicable waste <br />disposal regulations. It is not appropriate to <br />discharge untreated materials back to the <br />stormwater drainage system. <br />Part o( arranging for maintenance to occur <br />should include coordination of disposal o( <br />solids (landfili coordination) and liquid� <br />(municipal vacuum truck decant facilily, <br />local wastewater treatment plant, on-site <br />treatment and discharge). <br />Owners should contact the local public <br />works department and inquire about how <br />the department disposes of their street <br />waste residuals. Stormwater Management <br />Inc will determine disposal methods or <br />reuse of the media contained in the <br />cartridges. If the material has been <br />contaminated with any unu�sual substance, <br />the cost of special handlir,g and disposal <br />will be the responsibility of the owner. <br />Stormwalei Management, Inr. p2004 StormFilter Operation and Maintenance Guidelines 7 of 9 <br />
