Re: Proposal for 6 Months O&M / RASS Report

Pugh’s Dry Cleaners 215 South Bay Street Eustis, Lake County, Florida

FDEP Facility ID# 35 9500385 / ERIC_4814

Dear Mr. Talley:

Professional Service Industries, Inc. (PSI), an Intertek company, is pleased to provide the proposal contained herein to provide remediation system Operation & Maintenance (O&M) services for six (6) months and documentation of the remediation system performance with one Remedial Action System Status Report for the Pugh’s Dry Cleaners at 215 South Bay Street, Eustis, Florida. Included with this proposal is a discussion of project history to date, proposed scope of work, cost estimate and a proposed work schedule.

PROJECT BACKGROUND

Drycleaning operations at the Pugh’s Dry Cleaners began in 1948 and utilized petroleum solvent. In 1965, Pugh’s switched to tetrachloroethene (PCE) as the drycleaning solvent, which was stored in an AST located inside the building. Based on documented impact from the drycleaner, the facility was accepted into the Florida Drycleaning Solvent Cleanup Program in August 1998, and assessment activities commenced in December 2002 by Earth Tech.

Additional assessment wells were installed at the Pugh’s Dry Cleaners in January 2015 by PSI which revealed a high concentration of PCE (2630 ug/L) under the drycleaning machine beneath the building at a depth of 37-41 feet below land surface (bls). Two additional monitor wells were installed in March 2018, along with soil sampling for Soil Oxidant Demand (SOD) to assist in evaluating a groundwater remediation strategy.

mailto:Killian.Talley@FloridaDEP.gov

PSI Proposal Number: 0552-351830-Rev 3 FDEP – Pugh’s Dry Cleaners

An SVE system was installed in October 2009 by others and has operated intermittently since that time.

PSI has operated the system at varying cycling times since April 2012 to July 2016. The system was shutdown due to the drycleaning business use of PCE as their solvent. The business changed ownership in 2016 and switched from PCE to a non-chlorinated solvent fluid. The SVE system was subsequently re-started in October 2016 and continues to exhibit contaminant mass recovery. The system was turned off in preparation for shutdown, along with confirmation soil sampling in June 2021. The results revealed soil impact inside the building that exceeded SCTLs (2480 mg/kg at SB016) which indicates that the SVE system should be turned back on and operated to continue to remove contaminant mass.

We are, therefore, proposing to continue SVE system operation for the next six months.

PROPOSED SCOPE OF WORK

The proposal contained herein consists of utilities service and six, monthly O&M events with one report deliverable for the existing SVE system. The results will be used to confirm system operations and evaluate mass recovery rates as compared to remedial design. Specifically, the proposed scope of work consists of the following subtasks:

1. Project Management

This scope is provided for in the template worksheets.

2. Three Months of O&M (First Quarter)

Operations and Maintenance will be conducted on the SVE system. The work will be conducted as follows:

a. Mobilization to the site on a monthly basis.

b. Collect monthly vacuum and air flow readings from the SVE wells.

c. Collect monthly PID readings from SVE wells and system effluent.

d. Optimize system performance and recollect system readings as necessary to confirm enhanced system operation.

e. Collect quarterly system influent and effluent by Method TO-15, and samples from SVE

Wells #1, #2, #5, and #7.

f. Conduct individual Radius of Influence (ROI) tests on SVE wells #1, #2, #5, and #7.

g. SVE well #4 will be taken offline and left offline.

h. Inspect SVE Well #2’s structural integrity in an attempt to determine the cause of its reduced flow rate.

i. Document system readings in the site-specific O&M checklist; this checklist also serves as the deliverable.

j. The system will be cycled on a 50% duty cycle.

The Level of Effort is detailed in Subtask 2.

3. Three Months of O&M (Second Quarter)

O&M will be conducted once a month for three months as specified above with a monthly checklist as a deliverable. Air samples will be collected from five of the individual wells at the end of the second Quarter, as well as the influent and effluent with analysis by TO-15. The Level of Effort is detailed in Subtask 3.

4. Semi-Annual RASS

A Semi-Annual Remedial Action System Status Report will be developed which will include an evaluation of the collected information and data. The report will detail the monthly O&M information, along with summary tables, figures and a graphical depiction of the system performance. Vapor sampling results will also be submitted in the RASS report. The report will be prepared in accordance with the Technical Worksheets or similar documents, developed by the Drycleaning Solvent Cleanup Program. The report will include:

• Figure which depicts locations of MWs, SVE Wells, soil sampling locations, and former PCE dry cleaning machine(s). The calculated ROIs from the tests mentioned above should be illustrated on this figure when submitting the results of these tests.

• Table presenting which samples taken during the confirmatory soil sampling events were saturated.

Conclusions and recommendations will be made and will include a summary of any modifications made to the system to enhance the recovery rates or decrease system time. The report will incorporate specific recommendations and provide opinions based on professional experience in order to achieve the most efficient cleanup endpoints. We understand that the Department’s goal is to achieve aggressive contaminant reduction in an efficient and cost-effective method. The Level of Effort is in Subtask 4.

5. Utilities for remediation system operation

PSI used the previous utility costs at this project as well as from similar equipment at other sites as a basis for the utility costs, as detailed in Level of Effort Subtask 5. We anticipate running the system at 50% as per Department discussions.

COST ESTIMATE AND SCHEDULE

The estimated cost to perform the O&M for six months, along with one RASS Report deliverable is shown on the attached Cost Estimate. All PSI services will be conducted in accordance with the terms and conditions contained within DEP Contract No. HW552, Bureau of Waste Cleanup Consolidated Services, dated December 10, 2010. The services will be completed on a monthly basis upon authorization.

The O&M will start in October 2021 and continue for six months until March 2022 with the O&M checklists as a deliverable. The report will be submitted at the end of May 2022 (for the months October through March 2022 for the O&M).

PSI appreciates the opportunity to be of service to the FDEP. If you have any questions, please feel free to contact us at (813) 886-1075.
