Geosyntec° consultants the parking lot or Benjamin Hold Drive. The conveyance piping will be cut and capped below grade near the treatment system compound and at each of the SVE wells, SVE condensate removal stations, and SVE expansion box , At the AS supply will be pulled from the poly vinyl chloride (PVC) conduit and the PVC conduit will be capped within well vaults and at the treatment system compound. The conveyance piping in the south western portion of the Site between SVE-035 and SVE-034 is secured along the side and roof of the building as shown on Figure 3. This aboveground conveyance piping will be removed from the building. Where the conveyance piping enters the subsurface near SVE-035, SVMWE-002, SVMWE-001, and SVE-034, the pavement will be saw cut and the conveyance piping will be cut and capped below grade. The pavement surrounding well vaults will be saw cut and the vaults will be removed during the well destruction activities. After the wells have been destroyed (discussed in Section 3.3), the area will be repaved to match existing conditions. The pavement section is expected to include compacted subgrade, 6-inches of aggregate base rock, overlain by 4-inches of asphalt concrete. The three expansion box vaults (EB-2, 4, 5) and two condensate removal vaults (CRP-3 and CRP-5) are used by both the SVE system and the GETS. These vaults shall remain undisturbed while the GETS is in operation. Additional pavement repairs (resurfacing) will be made to portions above the conveyance pipe that have subsided and in area south of Benjamin Holt Drive were there is a high density of wells. These areas are highlighted in Figure 3. In these areas, a licensed contractor will make the necessary repairs and/or complete the repavement work. All pavement repairs will be completed to match the surface to the surrounding grade and materials in accordance with state and local building ordnances. 3.3 Well Destruction Well destruction will be conducted in accordance with SJCEHD Standards for Well Construction and Destruction in San Joaquin County dated February 2005.
