AGENDA ITEM 7C STAFF ORIGINATOR: David Ahrens, City Engineer/Public W orks Director DATE: September 5, 1996 TOPIC: Approve Consulting Engineer Agreement Remedial investigation for Underground Storage Tank Removal DACKOROUI D: The City currently has an underground storage tank and fuel dispensing system that has been replaced by a new fuel storage tank and fuel dispensing system. The abandonment of the existing system must follow Minnesota Pollution Control Agency (MPCA) rules that includes the following phases: 1. Preremoval Site Assessment this phase is complete with the report sent to the MPCA. The report states that the existing underground storage tanks "appear to be associated with a petroleum release" and remedial actions are required to be taken. 2. Remedial Investigation - this is the current phase of the cleanup project. This phase determines the degree and extent of the contamination. 3. Prepare cleanup plan - the Corrective Action Design includes a specific plan to achieve soil cleanup goals. 4. Perform cleanup. 5. Apply for reimbursement from Petrofund. Each phase of the cleanup process is eligible for Petrofund assistance. This assistance can be up to 90% of the costs to perform each of the above mentioned phases. Ineligible costs are the responsibility of the City and have been included in the 1996 budget. DISCUSSION: Two proposals were solicited per MPCA rules to perform a Remedial Investigation of the release site. Wenck Associates, Inc. submitted a proposal in the amount of $8,558.00. STS Consultants, Ltd. submitted a proposal in the amount of $8,968.00. Although STS Consultants performed phase 1 of the work and has some local knowledge of the site cleanup, staff is recommending that Wenck Associates receive approval to perform the Remedial Investigation work.
