Subject:

Proposal for Six Months of Operation and Maintenance Former Aristocrat Cleaners (ERIC_4071), 6745 Pembroke Road, Pembroke Pines, Florida

Dear Ms. Pepe:

Arcadis U.S., Inc. (Arcadis) is pleased to submit this proposal/cost estimate for the Former Aristocrat Cleaners Site, located in Pembroke Pines, Broward County, Florida. This proposal includes operation, maintenance and monitoring (OM&M) of the soil vapor extraction (SVE) system for six months (November 2020-April 2021), vapor sampling, groundwater sampling (annual event), 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 (November 2020-April 2021). 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 wells.

Additionally, depending on the seasonal variation in the groundwater table at

2/4 the site, monitor well MW001 may be utilized to measure the ROI of the SVE 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 2 QUARTER 4 (NOVEMBER 2020

THROUGH JANUARY 2021)

Task 2 consists of system monthly OM&M visits for one quarter (Month 22 through Month 24) and semi-annual reporting. During the fourth quarter the annual groundwater monitoring event will be conducted at MW001, MW006, MW007, MW008R, MW009R, MW010R, MW011R, and MW013 for VOCs. Recovered vapors from the SVE system will be monitored quarterly. A vapor sample will be collected in a Summa™ canister and analyzed for VOHs using EPA Method TO-15. 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., August 2020 through January 2021). The semi-annual report will also include results and data analysis of the groundwater and vapor monitoring events as well as recommendations to optimize system operation.

TASK 3: SVE SYSTEM OM&M YEAR 3 QUARTERS 1 (FEBRUARY THROUGH

APRIL 2021)

Task 3 consists of system monthly OM&M visits for one quarter (Month 25 through Month 27) and semi-annual 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 April 2021 OM&M event.
