The revised plan introduces phased closure of the Forward Landfill, provides an estimate of the maximum area to be closed, an updated anticipated closure schedule for the initial closure stage, and an updated closure cost estimate. Regional Board staff has the following comments about the plan: 1. Phased closure of the landfill will occur as landfill stages are filled and the waste is allowed to settle. Phased closure will enhance landfill containment by limiting the area of waste exposed to infiltration and will minimized the amount of gas and leachate generated. This is a positive outcome and staff concurs with the plan to close the landfill in stages. 2. e plan provides two dates for closure of Stage 1, on page 2 of the plan a date of 2015 is ven and on page 7 Section 1.5 states "the first staged closure project will begin in 2006". Table 2 estimates that closure construction will occur over 12 months (estimated completion in 2007?). Filling in most of the 217.8 acres in Stage 1 is complete and most of the remaining area will be complete this year (2004), therefore the 2015 date is probably a mistake and should be changed. 3. The preliminary cover design complies with Title 27, staff understands that a detailed closure plan with specifications and CQA plan will be submitted for each stage approximately two years before closure construction begins. 4. A gas extraction system will be designed into the landfill cover to prevent build up and release of landfill gas. This will be a requirement of future landfill closure plans. Staff concurs with the revised Closure/Post-Closure Maintenance Plan; the plan complies with Title 27 and will minimize the amount of landfill gas and leachate generated by landfill operations. Forward Inc. should submit- addendum to the plan by 31 arch 2004 clarifying the estimated date for closure'of Stage 1, if, a estimated date for start of Phase 1 is after 2006, the addendum should include justification -for -the later date.
