Dear Mr. Sostre:

Terracon Consultants, Inc. (Terracon) appreciates the opportunity to submit this proposal to the Florida Department of Environmental Program (FDEP) Waste Cleanup Section to revise the Interim Source Removal Plan and prepare the Pre-Construction Activities Plan for the above-referenced facility.

Scope of Services

Revise the Interim Source Removal Plan (ISRP) in accordance with the FDEP recommendations.

Prepare a Pre-Construction Activities Plan (PCAP) in accordance with the design specified in the revised ISRP.

Schedule

Deliverable Revised ISRP submitted within 20 business days following the proposal’s approval

Deliverable PCAP submitted within 40 business days following the revised ISRP approval

Compensation See attached CEF for details.

PROJECT BACKGROUND

Site assessment activities conducted in 2022 and 2023, which included Modified Active Gas Sampling (MAGS), indicated the presence of drycleaning solvent impacts in soil gas and groundwater, as summarized in the Site Assessment Report (SAR), dated April 28, 2023. The FDEP provided comments on the SAR on November 6, 2023, noting there were only sight detections exceeding GCTLs, and that

Proposal for Pre-Construction Activities Plan Majik Touch Cleaners and Laundry, ERIC_4714 | Valrico, FL March 5, 2026 | Terracon Proposal No. PH4267050 potential site access and facility compliance issues should be addressed prior to further groundwater delineation.

On January 30, 2026, Terracon submitted an ISRP, Revision 2, providing the design basis to implement a soil vapor extraction (SVE) system to reduce the PCE impacts within the vadose zone.

Terracon has prepared this proposal to revise the ISRP according to FDEP recommendations and initiate the pre-construction plans to implement the SVE system.

SCOPE OF SERVICES

The proposed scope of work consists of the following subtasks:

Subtask 1 – Project Management

Costs associated with this subtask are directly computed. Fabio Fortes will be the Project Manager, and Donna Cline will serve as the Authorized Project Reviewer (APR).

Subtask 2 – ISRP Modification

This subtask will include:

Labor hours to modify ISRP based on cycling SVE zones and 10 HP system;

Revise engineering calculations based on the proposed system configurations;

Identify a suitable SVE system within the current FDEP inventory, if available, to meet the revised design criteria; and Revise equipment specifications as appropriate in the Remedial System Summary and Construction Drawings.

Subtask 3 – Pre-Construction Activities Plan (PCAP)

The PCAP will be prepared according to the design specifications described in the revised ISRP. The proposed SVE wells will be installed from existing MAGS wells if they are in good working condition at the time of construction.

This subtask will include:

Site visit at Majik Touch Cleaners and Laundry (ERIC_4714) site with general construction and/or electrical subcontractors, property owner, and FDEP;

Updated construction plans, if needed, based on site visit and discussions with in-house personnel, subcontractors, property owner, and FDEP;

Review and select responsive remedial subcontractor; and Prepare the estimated schedule.
