Subject:

Proposal for Six Months of Operation and Maintenance Rivergate Dry Cleaner (ERIC_5413), 1193 SE Port Saint Lucie Blvd, Port Saint Lucie, Florida

Dear Ms. Pepe:

Arcadis U.S., Inc. (Arcadis) is pleased to submit this proposal/cost estimate for the Rivergate Dry Cleaner Site, located in Port Saint Lucie, Saint Lucie County, Florida. This proposal includes operation, maintenance and monitoring (OM&M) of the soil vapor extraction (SVE) system for six months (February 2025 – July 2025), vapor sampling, one semi-annual remedial action status report and one e-mail update. This proposal includes a description of the proposed scope of services, and an estimated cost and schedule for their completion.

TASK 1: PROJECT MANAGEMENT

As specified by FDEP, project management is calculated automatically in the CEF as the first subtask.

TASK 2 THROUGH TASK 3: GENERAL OM&M ACTIVITIES

In accordance with the approved ISRWP, the SVE system’s performance will be monitored monthly for six months (February 2025 – July 2025). The following will be performed during each monthly event:

The ROI of the SVE system will be measured by sequentially isolating the

SVE wells and measuring the vacuum influence of the nearby SVE or monitor wells.

Vapor extraction flow rate and vacuums will be recorded using meters and gauges located within the system. Adjustments will be made as necessary to optimize system performance.

The extraction blower will be inspected and adjusted for proper operation, including periodic oil changes, grease, and filter replacement.

The SVE system will be operated to minimize the capture and entrainment of groundwater.

The system interlocking controls and fail-safe mechanisms will be inspected for proper operation

Recovered vapors from the SVE system will be monitored quarterly. The SVE vapor sample will be collected from system influent to calculate mass removal.

TASK 2: SVE SYSTEM OM&M YEAR 1 QUARTER 2 (FEBRUARY THROUGH

APRIL 2025)

Task 2 consists of system monthly OM&M visits for one quarter and semi-annual reporting. The SVE vapor sample will be collected from system influent to calculate mass removal.

A Semi-Annual OM&M Report will be submitted at the completion of the quarter and include six months of system operational data (i.e., November 2024 through April 2025). The semi-annual report will include results and data analysis of the vapor monitoring events and recommendations to optimize system operation.

TASK 3: SVE SYSTEM OM&M YEAR 1 QUARTER 3 (MAY THROUGH JULY

2025)

Task 3 consists of system monthly OM&M visits for one quarter and quarterly reporting. A vapor sample will be collected from the influent sample port in a Summa™ canister and analyzed for VOHs using EPA Method TO-15 to calculate mass removal.

A Quarterly email update consisting of tables and figures will be submitted to the FDEP following the July 2025 OM&M event.

TASK 4: UTILITIES MANAGEMENT

This task will be used to manage and process FPL invoices for six months of system operation included in this proposal. Based upon prior FPL invoices, it is anticipated that the utility budget be estimated at $450 per month. A monthly handing fee of $20 per month is also included. Actual utility costs will be invoiced, and any differences will be adjusted through Task Assignment Change Orders.

SCHEDULE

Arcadis will begin implementing the OM&M activities in February 2025 upon receipt of a Task Assignment (TA) from the FDEP. The following deliverables and estimated timeframe for completion are included below:

Deliverable Anticipated Submittal

Date

Year 1 Quarter 1 & 2 Semi-Annual Remedial Action System Status Report May 2025

Year 1 Quarter 3 Email Update August 2025
