FROM: Nicole Knutson, Project Manager

SUBJECT: Negotiation Summary

HW689 DC014B-1

DATE: March 18, 2025

Due to shipping delays, the PFAS sampling kit was not delivered in time for the VOH groundwater sampling event. This Change Order authorizes APTIM to return to the Commerce Cleaners site to collect PFAS samples.

Total task amount has increased by $1,025.76. The price prior to this TACO was $14,108.31, and the amended price is $15134.07. APTIM’s time, labor, and subcontractor costs for these activities have been reviewed and are appropriate. The level-of-effort and cost estimate are reasonable for the scope of services. Final deliverable due date has been extended from April 18, 2025 to May 16, 2025. Task completion date has been extended from May 30, 2025 to July 18, 2025.

The following proposed Task Assignment Change Order (TACO) #1 has been prepared for the former Commerce Cleaners site located in Jupiter, Florida. TACO #1 has been prepared to allow for a second site visit to perform the expanded PFAS sampling. During the initial site visit, the PFAS samples could not be collected due to late delivery of the FDEP State Laboratory kit request.

Subtask - 1: Project Management This task includes project management activities associated with the completion of the remaining Tasks, as calculated in accordance with Contract HW689.

Subtask - 2: Annual Groundwater Sampling (VOHs): No Changes Subtask - 3: Annual Groundwater Reporting (VOHs): No Changes Subtask - 4: Additional PFAS Sampling and Reporting TACO #1 includes an additional site visit to purge and sample the expanded monitoring wells for PFAS. The wells proposed to be sampled included MW002, MW003, MW006, MW007, MW011 and MW012D. Unfortunately, during the initial VOH groundwater sampling, the PFAS samples could not be collected, due to a delay in the delivery of the sample kit from the FDEP State Laboratory in Tallahassee. TACO #1 will allow for a second visit for the collection of the samples, and includes labor, equipment, a vehicle and expendables to complete the sampling.

To allow for scheduling, collection of the additional samples, laboratory analysis and reporting, an additional 30 days is requested, which will place the Annual Groundwater Monitoring Report to May 18, 2025, and the TA Completion Date to June 29, 2025.

APTIM proposes to perform this scope of work in accordance with the terms and conditions of the Contract between the Florida Department of Environmental Protection and APTIM dated December 21, 2021 (DEP Contract No. HW689). APTIM will begin the proposed scope of work upon issuance of the Task Assignment Notification.
