JIM. TMURPE. UIL INU Croy aca sorra and elevated detection levels due to heavy late eluting matrix in- terference. No other samples were taken at that time. Spoil was piled to the north of the excavation and remains there at the time of this writing. A cyclone fence was placed around the excavation and it remains in place as well . 6 . Remediation Steps: Mr. Largin has retained Wm. Hunter and Associ- ates and Jim Thorpe Oil Co. , Inc. to undertake the next phase of this cleanup project. After consultation with Wm. Hunter and Jim Thorpe Oil Co. , Inc. , Mr. Largin has decided to remove as much of the contamination remaining beneath the tank pits as possible by over-excavation. The proposed excavation will start at the west- ern end of the original excavations to a depth of approximately 201 , 41 north of the north boundaries and extend southerly to a point approximately 41 past the south boundaries distance of ap- proximately 201 . Then easterly a distance of approximately 70' or 5' past the and of the original excavation. The resulting excava- tion will be 201 wide, 70' long and 20 feet deep (see attached drawings) . Adjustments can be made if necessary. The total amount of additional soil to be removed will be approximately 250 cubic yards for a total of approximately 400 cubic yards including pre- viously excavated soil . Every effort will be made to separate contaminated Boil from the clean. Clean soil will be stored on- site for use in backfill operation. Obviously contaminated spoil, will be placed on plastic sheeting and covered with same if neces- sary. when actual volume and contamination levels are ascer- tained, determinations for the disposition of the spoil will be made. 7 . Soil Samplings Soil sampling will be accomplished by retrieving samples from the appropriate areas with the excavator bucket . Samples will be taken from the bucket by Wm. Hunter & Associates representative on-site. All sampling and analyses will follow LUFT guidelines . Samples will be transported by Wm. Hunter & As- sociates directly to Fruit Growers Laboratories, located in Stock- ton, CA under chain of custody. Soil Sample analyses results sheets will be mailed directly to SJPHS/BHD from FGL. Samples will be tested for TPR-G, and BT9&X. We propose to take 8 side- wall and 3 bottom samples from the excavation. Samples will be taken equidistant around the perimeter and along the length of the bottom of the excavation [see attached drawing3 . Locations of the samples may change at -the direction of SJPHS/EHD representative on-site. We propose 4 samples (8 discrete to form the 4 compos- ites) from the spoil pile at the direction of the SJPHS/EHD repre- sentative. The total number of samples may be altered if conditions or volumes warrant a change. 2
