Product piping will be flushed with water and again pumped dry prior to removal. All collected <br /> fuel and wash water will be placed in DOT approved 55-gallon containers and stored on-site for <br /> subsequent manifesting and disposal. Universal Environmental of Benicia, CA will haul <br /> generated liquid wastes for offsite disposal. Liquid wastes will be disposed/recycled at Crosby <br /> and Overton in Oakland California. Once decontaminated, existing primary fuel lines will be <br /> pulled from their ducts and hauled for off-site disposal by Glacier as solid waste. Solid waste will <br /> be disposed of at the Forward Landfill in Manteca, California. <br /> During removal of the primary fuel pipes, copper wire will be pulled into the secondary <br /> containment ducts to allow locating with electromagnetic equipment. Glacier will saw-cut, break <br /> and remove concrete over the existing lines and excavate for removal. Removed duct will be <br /> decontaminated as necessary and hauled to the Forward Landfill for solid waste disposal. <br /> Concrete will be similarly cut and removed around dispenser and tank sumps. Soil will be <br /> excavated to expose tanks sump penetrations and replace under dispenser containment. <br /> Concrete will be similarly saw-cut, removed and excavation completed for installation of Phase 1 <br /> EVR. Broken concrete will be loaded to a Glacier truck for transportation to the Forward landfill in <br /> Manteca, California <br /> • Excavated soil will be stockpiled and covered on-site and reused during backfill. 7-Eleven's <br /> environmental consultant will sample stockpiled soil, soil along the existing pipe alignment and <br /> below removed dispenser sumps. Soil sampling, profiling and disposal (if required) will be as <br /> described in the enclosed Workplan for Soil Compliance prepared by Seacor International, Inc. <br /> • New EnvironTM" coaxial pipe will be installed in the trenches excavated for removal of the existing <br /> pipe. All containment sump boots will be replaced with EnviroTM. Catalog cut sheets for the <br /> proposed EnvironTm products are attached for your review. Electrical conduits will be temporarily <br /> removed and reinstalled with new entry boots by a licensed electrical contractor. <br /> • All installed components including the existing dispenser and turbine sumps will be field tested by <br /> Glacier prior to agency inspection. Glacier will provide the agency with adequate notice for pre- <br /> burial inspection. <br /> • Following inspection of below grade completion, excavations will be backfilled, compacted and <br /> concrete restored to match existing. Dispensers will be set, lines purged and the gas facility <br /> reopened. <br /> • Glacier will coordinate with Tanknology Northwest for completion of tank, line and sump testing <br /> upon completion of site work. <br /> This workplan has been prepared by Glacier for agency use in reviewing and approving the enclosed <br /> permit application(s).
