NOV 20 195 06:40PM C1 _ 4WHTER GROUP � P.4/6 SAW CLEARW.�JER G R U U P, [ N C, • - contractor and landfill charges should be eligible for reimbursement due to the fact that if the soil was clean it would have gone back in the excavation immediately after tank removal. Backfill and Compact Excavation In accordance with PHS/EHD requirements, approximately 720 cy of clean soil (no sand or pea gravel) will be used to backfill the excavation. The soil must be compacted to meet ASTM standards. . This work includes the removal and disposal of trees and roots, removal of existing fence, prep for backfilling, import of approximately 40 loads of clean, compactible fill dirt and compaction to 95%. The area will be capped with road base and compacted to 95%. In requesting bids for this work, Jeanna prepared a specific scope of work so that each contractor understood the details of the backfill plan. Jim Thorpe Oil won this phase of work with the lowest bid. He is also the original contractor who removed the underground storage tanks at this site. It is very important that the backfill and compaction meet the required specifications so that during future cleanup we will be working with a subsurface that is conducive to remediation. In addition we will be advancing a cone penetromenter (CPT) through the former tank area. This requires driving a 20 ton CPT unit on top of the backfilled area. It is extremely important that the backfill be done correctly or the possibility of the unit sinking into that area exits, Bruce Inman has indicated that you would like to hire the contractor directly for this task. I see no problem with this as long as Jim Thorpe Oil is used. If another contractor is used they must be properly briefed by Jeanna regarding the project specifications and their bid must be lower than Jim Thorpe's. Cost Implications: Since this scope of work has already been pre-approved by the State Fund, Clearwater will wait for payment until you have been reimbursed. Due to the issue of reimbursement eligibility of this task, I recommend that we proceed with a few modifications. You can hire the contractor directly, thus incurring no mark up costs. Direct costs to you would be the cost of the clean fill soil. Assuming 720 cy at $8.34/cy the total is $6,004.80. (Much of this cost may be unnecessary if we are able to use the stockpiled soil). The cost for hauling, backfill, and compaction by Jim Thorpe Oil is $7,288.92. Again, I would a.aticipate that a majority, of these charges will be eligible for reimbursement. Well Installation and CPT Borings In order to be able to proceed with this phase of work in a timely manner, we need to begin permitting now. I would anticipate that if we began working on obtaining permits on Monday, and submitted our Caltran's permit application before Thanksgiving, our longest lead time would be six weeks for 3
