Title
Resolution to Approve Amendment No. 3 to the Professional Services Agreement with Tetra Tech, Inc. for the Ann Arbor Landfill Monitoring and Maintenance Program for PFAS and Other Sampling and Monitoring (Estimated $351,124.00 Annually) and to Approve a Consulting Services Contingency Amount ($40,000.00 Annually)
Memorandum
Attached for approval is a resolution approving Amendment No. 3 to the Professional Services Agreement with Tetra Tech, Inc. ("TTI") (R-17-255) for environmental consulting services for the Ann Arbor Landfill Monitoring and Maintenance Program, beginning July 1, 2019 through June 30, 2021. The total contract cost amendment will be $351,124.00 per year, with an annual contract contingency of $40,000.00.
This amendment will help satisfy new testing requirements -- and additional requests received from government entities for PFAS and other similar monitoring -- that the Michigan Department of Environment, Great Lakes, and Energy (formerly MDEQ) is requesting on groundwater at the landfill and adjoining properties. It is anticipated that sampling and monitoring will increase in frequency in the coming years, and become an ongoing and reoccurring task.
Budget/Fiscal Impact: Funding for this program has been budgeted in the FY20 Solid Waste Operation and Maintenance budget and will be made available in the FY 21 Solid Waste Operation and Maintenance budget if so approved by Council.
