maintenance buildings are portable structures which will be removed during <br />closure construction. <br />Structure removal will be performed to minimize impacts to the site. Areas <br />where structures have been removed will be graded and seeded for erosion <br />control. All gates and fences will remain in order to control access to the facility <br />during the post -closure maintenance period. - <br />3.13 DECOMMISSIONING OF ENVIRONMENTAL CONTROL SYSTEMS <br />The environmental control systems at the Forward Landfill that will require <br />decommissioning after the post -closure period are the leachate evaporation <br />ponds and the leachate collection pumps. Currer`tly, the°leachate evaporation <br />ponds are planned to be closed in place in accordance with Title 27 CCR, <br />Section 21400. The leachate collection pumps will be cleaned and reused, if <br />possible, or dismantled and disposed of at an appropriate facility.. Costs for <br />decommissioning of these facilities are included in the Annual Post -Closure <br />Maintenance and Monitoring Cost Estimate Summaryincluded as "Table 6. <br />Other environmental control systems will be dismantled either during or at the <br />end of the post -closure period.when it has been.dernonstrated.that there is .no <br />need for the system. Components of these systems that have come into contact <br />with leachate will be transported and disposed of at another solid waste'facllity <br />that is approved for receipt of such materials. Transportation and disposal will <br />be managed to avoid the introduction of leachate or waste constituents into the <br />environment beyond the site boundary. <br />Environmental controls that must be decommissioned in place will be closed in a <br />manner that minimizes future maintenance, allows for inspection of closure <br />integrity and conforms with all applicable laws and regulations and standard <br />engineering practices at that time. If environmental control systems can be <br />reused at another facility, they will be cleaned in accordance with the <br />appropriate requirements. <br />The groundwater, vadose and landfill gas control monitoring systems will be <br />closed and secured when they are no longer required, but will remain in place. <br />IP t <br />Forward Landfill PCPCMP 3-15 <br />L:\Allied\2000.193\Reports\FinaIPCPCMP:FL-sec3: 8/20/01 BRYAN A.
