The following Task Assignment Change Order (TACO) #2 has been prepared to adjust costs for the former Spring Lake Cleaners site located in Winter Haven, Polk County, Florida. The proposed scope of work under this TACO reconciles Subtask 3 for invoicing.

Subtask 1-Project Management Project management hours are calculated based on the labor hours in the scope of work.

Subtask 2-Meeting & MAGS/Soil Sampling: No Changes

Subtask 3-DPT & GW Sampling Field Activities Labor hours associated with the geologist proposed to provide assistance with the DPT groundwater sampling was not available at the time the work was performed; therefore, the associated hours have been removed from the Subtask.

Subtask 4-Well Installations: No Changes Subtask 5-SAR Reporting: No Changes Subtask 6-Additional PFAS Sampling: No Changes

To allow for FDEP review of the DPT findings and recommendations submitted on September 23, 2025, completion of the site work and preparation of the Site Assessment, a deliverable extension for the Site Assessment Report (Subtasks 4,5 and 1) and FPAS Reporting (Subtask 6) of 90 days is requested. The extension would change the Site Assessment Report and PFAS Reporting deliverable dates to February 12, 2026. The extension would adjust the Task Assignment Completion date to April 16, 2026.

APTIM proposes to perform this scope of work in accordance with the terms and conditions of the contract executed between APTIM Environmental & Infrastructure, LLC and Florida Department of Environmental Protection No. HW689. APTIM will begin the proposed scope of work upon issuance of the Task Assignment Notification.

If you have any questions, please contact us for clarification.
