WS presented Professional Services amendment in the amount of $18,000 (The figures do not; yet include contractual mark-up by HKT) to cover professional services for IRA Plan Preparation as required by DEP, installation of monitoring wells, as required by DEP and solicitation of quotes for removal of on site material already approved for removal. Weston and Sampson 7/2/08 Revised Proposal approved by PBC in the amount $18,000 Motion: Eric Brown 2nd Bill Kennedy Vote: Unanimous The PBC was further concerned that given the nature of the work WS is performing and the time sensitivities involved, that they should authorize Pat Goddard the ability to approve continued or further authorizations to Weston & SampsonÔs contract if required to keep the environmental issue moving forward and to not cause or worsen delays to the project. Motion: To authorize Pat Goddard to act on behalf of the PBC to expand up to an additional Twenty Five Thousand Dollars ($25,000.00) in addition to the $18,000 approved at this meeting, to advance Weston & Sampson scope for site investigations and work related the current soil contamination matter. Motion: Jon Himmel 2nd Bill Kennedy Vote: Unanimous 8/12/08 Weston and Sampson presented a report, copy on file, regarding the status of work, evaluations, testing and findings to date. To Date W&S has prepared the Immediate Response Action Plan &submitted it to DEP. Monitoring wells were also installed per the DEP requests. Minor imperfections were found in water sampling to date. Test pitting operations were completed for this phase of the work as well as the GPR survey. Two areas were identified for removal of contaminants, one being the area of known drums and the second being the area with the asbestos pipe. These areas need to be excavated and contaminants removed and further soil samples taken. Proposal was submitted for additional W&S work: Task 13 Removal of soil stockpile and roll off containers with contaminants. At $64,319.00 Task 14 Drum area excavation and disposal at $49,648.00 Task 15 Tar and asbestos pipe area excavation and disposal at $46,186.00 Task 16 Project Management, data Review and MCP Support. At $31,318.00 These Tasks Total $191,471. This work would be subject to HKT mark-up of W&S Soft Costs. Motion made to approve tasks 13-16 of the Weston & Sampson proposal, dated 8/8/08, which does not yet include HKT Mark-up, at a cost of up to ($200,000.00) Two Hundred Thousand Dollars, with the understanding that there is sufficient contingency in the Project Budget to cover these costs, and knowing that the scope may not fully be defined until excavations & final testing are complete. Motion: Dick Perry 2nd Bill Kennedy Vote: Unanimous 9/9/08 Since last meeting contaminated soil piles have been removed. Excavation for test pitting complete. Removed 1 piece of asbestos pipe. Removed 16 drums with petroleum type product. All soils and roll offs removed. DEP needs status reports, Weston and Sampson working on said report. Remediation cost about $20,000 less than expected to date. Site closure, deed restriction could be considered in the future. Weston and Sampson will make recommendations based upon DEP response to reports. Submission of trial testing data and reports to DEP will tell us of remainingscope. 10/14/08 Excavation for underground storage tanks and fuel island was started and then stopped due to excessive ground water in location. Testing on ground water showed that water could not be discharged to storm water without filtering. Alternate plans developed to remediate ground water issue on site and reflected in need for W&S score items 17 & 18. Approval to have W&S to perform Task 17 and 18.
