This document is a Task Assignment Change Order (TACO) Number 2 issued by the State of Florida Department of Environmental Protection (FDEP) for contract HW687 with Terracon Consultants, Inc. The project involves supplemental site assessment and remediation activities at the Broward County School Board Property in Plantation, Florida (Site ID: ERIC_18360). The contract manager for FDEP is Megan Johnson, and the contractor's project manager is Shawn Ouellette. The TACO was executed in April 2026 and amends the original Task Assignment (BIL02C) to reconcile work authorized under three Work Change Directives (WCDs) issued between January and February 2026.

The TACO increases the total task assignment value from $15,189.75 to $48,896.49, representing a cost increase of $33,706.74. This increase encompasses: Subtask 5 (Supplemental Soil Assessment under WCD #1) with an increase of $13,566.62 for additional soil sampling, GPR locating, drilling, laboratory analysis, and updated excavation calculations; Subtask 6 (Voluntary Source Removal Plan under WCD #1) with an increase of $2,861.85 for plan development; Subtask 7 (TCLP Analysis under WCD #2) with an increase of $1,750.00 for specialized laboratory analysis of ten samples; and Subtask 8 (Additional Supplemental Soil Analysis under WCD #3) with an increase of $13,358.03 for further soil sampling, waste profile preparation, and updated remedial analysis. The task assignment completion date was extended from January 12, 2026 to June 26, 2026, a total of 57 additional days. Deliverables include field documentation, site assessment reports, remedial alternatives evaluations, and a voluntary source removal plan, with invoicing contingent upon FDEP approval of each deliverable component.

DATE: April 13, 2026

SUBJECT: Negotiation Summary – BIL22 Task Assignment (TA) Change Order #2 BIL02C C2 Broward County School Board Property – Site ID # ERIC_18360 Supplemental Site Assessment activities

This Task Assignment Change Order (TACO) reconciles work authorized under Work Change Directives (WCD) 1, 2, and 3, executed on January 8, 2026, January 30, 2026, and February 18, 2026, respectively. There are no scope or cost changes associated with Subtasks 2, 3, or 4.

Specific changes are detailed below:

Subtask 1: Project Management Under this subtask there was an increase in project management hours due to an increase in labor hours needed for the activities under Subtasks 5, 6, 7, and 8. This change resulted in a cost actual increase of $2,170.24.

Subtask 5: Supplemental Soil Assessment Following the submittal of the draft Remedial Alternatives Evaluation, Terracon, the Department, and Broward County held a meeting to discuss next steps. It was determined additional soil sampling was needed to better refine the future excavation boundaries. WCD #1 was approved for this additional sampling. This resulted in a cost actual increase of $13,566.62.

Subtask 6: Voluntary Source Removal Plan Additionally, under WCD #1, a Voluntary Source Removal Plan was requested by Broward County to define the scope and construction practices that will be employed. This resulted in a cost actual increase of $2,861.85.

Subtask 7: TCLP Analysis on Exceedances Following the receipt of preliminary laboratory results from the additional soil sampling done under Subtask 5, it was determined TCLP should be run on select samples for disposal evaluation. This was approved under WCD #2. This resulted in a cost actual increase of $1,750.00.

Subtask 8: Additional Supplemental Soil Analysis WCD #3 approved further supplemental soil sampling to refine excavation limits, update the Remedial Alternatives Evaluation, and to prepare and submit a waste profile to be utilized in the proposed Voluntary Source Removal Plan for identification of the disposal facility and costing. This resulted in a cost actual increase of $13,358.03.

April 13, 2026 www.FloridaDEP.gov

Summary The Department’s BIL Contract Manager and Terracon’s Contract Manager have both agreed to the above changes. All changes noted above represent a total overall cost increase of $33,706.74, as shown in the Final/Cost Actual LOE. Due to a rounding error in Excel, the Delta LOE states an overall cost increase of $33,706.72, however this was addressed in the Cost Actual LOE. The changes were noted in the TACO Request received from Terracon on April 8, 2026.

The final cost associated with this TA increased from $15,189.75 to $48,896.49. Documentation of the changes is included in the attached TACO Request, the Delta LOE spreadsheet and the Cost Actual LOE spreadsheet, and the TACO form for BIL02C C2 prepared by the Department.
