0 1POST-CLOSURE <br />U <br />Post -closure maintenance of the Forward Landfill Stage IA partial closure area <br />will be performed in accordance with applicable regulatory standards included in <br />27 CCR, Chapters 3 and 4, and 40 CFR Section 258.61. Post -closure <br />maintenance activities for the Stage IA partial closure area of the Forward <br />Landfill will consist of: <br />• Final Cover Maintenance <br />• Drainage System Maintenance <br />• Vegetative Cover Maintenance <br />• French Drain Leachate Seep Collector Maintenance <br />• Bench Maintenance <br />• Landfill Settlement Monitoring and Monument Maintenance <br />The maintenance procedures for each of these activities are described in the <br />following sections. Please note that landfill gas monitoring and control system <br />maintenance, groundwater monitoring, and site security for those facilities in the <br />Stage IA partial closure area will be performed/maintained as part of ongoing <br />landfill operations. <br />4.2 FINAL COVER MAINTENANCE <br />The integrity and effectiveness of the final cover will be maintained by making <br />repairs, if necessary, to correct the effects of settlement, subsidence, erosion, or <br />damage to the vegetation. Areas that show evidence of damage will be <br />investigated to ascertain the cause of the damage before repairs are undertaken. If <br />the damaged areas have caused ponding of surface runoff, soil will be added as <br />needed and regraded until positive drainage is re-established. If the repaired area <br />is large enough, it will be revegetated. Inspections of the final cover will be <br />performed on a quarterly basis. <br />Forward Landfill PFCPCMP 4-1 <br />J:\Allied\Forward\2005.0051 Partial Closure\Partial Closure Plan\FL•sec4.doc: 6/9/2005 <br />
