Neither process solution <br /> application, nor process solution storage will occur in the areas covered by the proposed new liner composite system. This <br /> project included the installation of single-sided textured 80 mil Linear Low Density Polyethylene("LLDPE"). This project No Costs, as this is <br /> TR-62 included the construction of an enhanced containment berm along the Phase IV liner perimeter in order to increase the Covered under VLF <br /> capacity of the area to withstand upset process solution conditions. This is an extension toward the west of a previously Reclamation. <br /> completed project referenced in Technical Revision No. 52 dated October 30, 2008. There is no additional reclamation <br /> associated with these projects, as they will all be covered in the physical reclamation of the VLF. <br /> New Fuel Island Construction-A significant number of tanks were installed at the new Midway Fuel Island in 2012 and Costs are Covered in <br /> TR-63 demolition of these tanks has been accounted for in the 2012 revision to the Internal Model.
