04 January 2013 AGE -NC Project No. 12-2179 Page 5 of 7 For landfill projects, there are always elements of unknown. Therefore, the expansion of all activities should be expected in the event that design volumes have been miscalculated or are determined to be `off'. In addition to the "green" benefits of recycling on-site soil and native plants material, utilizing these materials as stockpiles will reduce the borrowed volume considerably, ultimately reducing the cost of moving soil or hauling soil on-site (truck transmission). For the proposed corrective action, a construction contract will not be required; hauling of clean soil to create the cap of the landfill, will be conduced in its entirety by the property owner. The property owner will allow a minimum of two months to complete the closure, which allows for typical construction downtime, due to winter rains and soil management. 4.0 CAPPING LANDFILL AREA After reviewing the 14.7 -acres of usable land, the site soil source, will be able to supply soil for an area of only about three acres. The three acres will have restrictions on construction activity due to new cover, steep slopes, protection zones for oak trees (west side) and road way proximity. The contractor is required to excavate or grade 2,200-2,500 cubic yards of material, stockpile soil for cover media and compacting soils that meets the goals for the project, minium daily cover. Additional natives soils, gravel, road -base or other semi -recycled non-native road base will be imported to support the cover of all the former landfill area or to allow for proper drainage. A typical construction day will consist of one CAT D8 excavator moving soil from the surface borrow piles to the open face of the exposed waste excavation at a rate of 1,200- 1,500 cubic yards per day. The strategy for closing the landfill is to begin in the area of most uncertainty, the area where illicit dumping might have occurred (less thickness of waste), and work toward the west (Sante Fe Road), which had definitive boundaries as the old dumping area. This will be done with the intent that there will be fewer "surprises" regarding the landfill's extent and contents as the project progresses. This has the additional benefit of keeping rain from leaching through uncovered waste, prior to compaction of soil cover. Supporting the excavation operation will be a scraper and possibly a loader which can stage the stockpile on an undisturbed portion of the landfill cap. If the scraper is unable to perform the above scope of work, a front loader will be alternatively used to segregate waste stockpiles from screened soil and concrete stockpiles. A water truck will provide dust control for the entire operation. When required, a fuel/service truck should arrive on-site, to fuel and grease all equipment. When backfill operations are occurring, two additional laborers will manually remove or relocate debris from the material that is being backfilled. Advanced GeoEnvironmental, Inc.
