SUBJECT: Negotiation Summary

HW689 DC028A CO1

DATE: September 8, 2025

This Change Order reduces IDW costs to reflect the actual volume of purge water produced. The original cost proposal included T&D for a 55-gallon poly drum. The revised cost proposal includes T&D for a 5-gallon bucket of PFAS-contaminated purge water.

Total task amount has decreased from $9,954.72 to $9,769.72. The difference between the revised cost and the original cost is $185.00. 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 remains July 25, 2025. Task completion date remains September 30, 2025.

The following is the proposed scope of work for Task Assignment Change Order (TACO)

DC028A TACO #1 to reconcile the Task Assignment (TA) for invoicing.

Subtask 1: Project Management

Project management hours are calculated based on the labor hours anticipated in the scope of work.

Subtask 2: Biennial Sampling: No Changes

Subtask 3: Biennial Groundwater Report: No Changes

Subtask - 4: Additional PFAS Sampling and Reporting

The costs for transportation and disposal (T&D) of the investigative derived waste (IDW) was less than anticipated based on the volume produced. The original estimate proposed the use of a poly drum for storage and T&D of the IDW. Based on the volume, a poly drum was substituted for a 5-gallon bucket. Therefore, the cost of the poly drum has been removed from the Subtask. Additionally, the cost for T&D was reduced.

The current TA Completion date of September 30, 2025, should be sufficient to process the

TACO and invoice the TA.

APTIM proposes to perform this scope of work in accordance with the terms and conditions of contract No. HW689 executed between Florida Department of Environmental Protection and

APTIM Environmental & Infrastructure, LLC. APTIM will begin the proposed scope of work upon issuance of the Task Assignment Notification. This site has a current Access Agreement dated

10/7/23 for site entry.
