Proposed Scope of Work Oasis Cleaners (former) DC015D 3210 1st Street West, Bradenton, FL Task Assignment DC015C TACO #4 ERIC_4885 (Former FAC ID No. 419500357) Aptim Environmental & Infrastructure, LLC (APTIM) April 1, 2026

The following proposed Task Assignment Change Order (TACO) #4 for the former Oasis Cleaners facility reconciles the costs associated with the authorized scope of work.

Subtask - 1: Project Management This task includes project management activities associated with the completion of Subtasks 2 through 9, as calculated in accordance with Contract HW689.

Subtask 2: Qtr. 1 O&M Reporting: No Changes

Subtask 3: Qtr. 2 O&M Reporting

TACO #2 which is in Subtask 3, authorized the purchase and installation of an optical water level detector that would be placed at the top of the well casing. Operation of this device required modifications to the control panel to receive a 4-20 milliamp analog signal or other digital response to changing groundwater elevation changes. Unfortunately, a cost-effective unit that could fit within the well casing and manhole could not readily be found so the modification was not performed. The high groundwater elevation condition that would allow water entrainment into the remedial system is now managed by adjusting the vacuum extraction pressure, isolating specific vertical SVE wells and adjusting zone operation. The cost reconciliation for this system modification removes 8 personnel hours from ST 3, removal of $966 fee from subcontractor PRM and removal of the optical sensor for $663.50. Total cost reduction for Subtask 3 is $2,510.41.

Subtask 4: Utilities One Month: No Changes

Subtask 5: Semi-Annual Reporting: No Changes

Subtask 6: Qtr. 3 O&M Reporting: No Changes

Subtask 7: Qtr. 4 O&M Reporting: No Changes

Subtask 8: Utilities One Month: No Changes

Subtask 9: Annual O&M Reporting: No Changes

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