12 December 1997 <br /> AGE-NC Project No. 97-0312 <br /> Page 2 oft <br /> excavation and historical high ground water. Using the leaching potential analysis table (LOFT <br /> Manual 1989, Table 2-1), maximum allowable concentrations for TPH-g and TPH-d to remain in soil <br /> are 100 ppm and 1,000 ppm, respectively. A completed LUFT manual table is attached. <br /> We propose to use part of the stockpiled soil to backfill the UST excavation at the site. Portions of <br /> the stockpiled soil with concentrations of TPH-g less than 100 ppm and TPH-d less than 1,000 ppm <br /> will be used to backfill the excavation. The remaining soil will be transported to an appropriate <br /> disposal facility. Remaining soil necessary for backfilling the excavation will be imported. An amount <br /> of clean fill material equivalent to the exported soil will be imported to backfill the excavation. The <br /> imported fill material will be placed toward the bottom of the excavation; stockpiled soil will be <br /> placed near the surface. Backfilling of the excavation will be performed in accordance with section <br /> 3.1. of the Interim Remediation Work Plan - October 1997 prepared by AGE. <br /> The opportunity to provide you with this service is greatly appreciated.
