Re: Proposal for 12 Months O&M / RASS Report Westwood Cleaners

4513 Gunn Highway Tampa, Florida, 33624 Facility ID No. 29950774, ERIC_4706

Dear Ms. Schwed:

Professional Service Industries, Inc. (PSI), an Intertek company, is pleased to provide the proposal contained herein to provide twelve months of remediation system Operation & Maintenance (O&M) services, quarterly email summaries of system operations, and documentation of the remediation system performance with the development of two Remedial Action System Status Reports, for the former Westwood Cleaners located at 4513 Gunn Highway, Tampa, Florida.

Included with this proposal is a brief discussion of project history to date, proposed scope of work, cost estimate and a proposed schedule for completion.

PROJECT BACKGROUND

The Westwood Cleaners operated from 1984 to 2003 and occupied a tenant space on the east portion of a multi-tenant commercial shopping center in Tampa, Florida. The cleaners operated one tetrachloroethene (PCE) drycleaning machine and the facility has two floor drains. Based on results from the Site Screening activities in May 1997 showing PCE in the soil at a concentration of 700,000 micrograms per kilogram (µg/kg), the drycleaner business was accepted into the Drycleaning Solvent Cleanup Program. The soil sample was collected near the backdoor of the drycleaner building.

The former Westwood Cleaners tenant space is currently a martial arts studio, Carrollwood Tae Kwon Do, that trains students typically on weekday afternoons. The business has been remodeled mailto:Skylar.Schwed@FloridaDEP.gov

FDEP – Westwood Cleaners, O&M, RASS with an elevated bamboo floor for the martial arts training. No drycleaning equipment remains at the former drycleaners.

A Site Assessment / Interim Source Removal Plan was prepared by PSI for the FDEP and was submitted August 29, 2018, and subsequently approved by the FDEP on May 20, 2019. Of note is the very high PCE concentration detected in the shallow well installed next to the former dryclean machine at 64,000 ug/L in February 2018, 12,000 ug/L in April 2020, and 9,300 ug/L in March 2021. The Interim Source Removal (ISR) Plan consisted of addressing the contaminant mass such that additional contaminant contribution to the surrounding soil and groundwater is minimized using Soil Vapor Extraction (SVE) technology.

An SVE system was installed in October through December 2019 at the Westwood Cleaners facility, with start-up in December 2019.

The system has been operating since December 2019. As outlined in the most recent FDEP comments, it was recommended to continue O&M operations. Additionally, it was recommended by the FDEP to develop a Remedial Alternatives Evaluation (RAE) to address the high concentrations of VOH compounds at the site. A RAE Scope of Work was submitted in February 2023 and included updating the groundwater monitoring along with various remediation parameters. We anticipate initiating work for the RAE upon authorization of a Task Assignment.

Therefore, the proposal contained herein for the O&M does not include groundwater sampling and analysis.

PROPOSED SCOPE OF WORK

The proposal contained herein consists of utilities service and twelve-monthly O&M events with two report deliverables for the existing SVE system, quarterly email summaries, and reporting.

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. Based on FDEP’s recommendation, we will continue to operate SVE001, SVE002, and SVE003, and leave closed the SVE wells outside, SVE004, SVE005, and SVE006.

e. Collect quarterly system influent and effluent samples, and samples from the three operating SVE wells for analysis by Method TO-15. The FDEP engineering group comments recommended collecting all SVE samples for the first quarter.

f. Document system readings in the site-specific O&M checklist.

g. Quarterly update via email to the FDEP on system operation.

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. Air samples will be collected from the influent and effluent and analyzed by TO-15. A summary of system conditions will be submitted via email to the FDEP each quarter.

The Level of Effort is detailed in Subtask 3.

4. Semi-Annual RASS Report

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 and summarize the monthly O&M information, along with summary tables, figures and a graphical depiction of the system performance. Vapor sampling results will be submitted in the RASS report. The report will be prepared in accordance with the Technical Worksheets or similar guidance documents, developed by the FDEP Drycleaning Solvent Cleanup Program.

Conclusions and recommendations will be made, which will include a summary of modifications made to the system to enhance the recovery rates or decrease system time to achieve targeted goals. 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 detailed in Subtask 4.

5. Three Months of O&M (Third Quarter)

O&M will be conducted once a month for three months as specified above. Air samples will be collected from the influent and effluent and three of the SVE wells at the end of the third quarter of the year and analyzed by TO-15. A summary of system conditions will be submitted quarterly via email to the FDEP.

The Level of Effort is detailed in Subtask 5.

6. Three Months of O&M (Fourth Quarter)

O&M will be conducted once a month for three months as specified above. Air samples will be collected from the influent and effluent and analyzed by TO-15. A summary of system conditions will be submitted quarterly via email to the FDEP.

The Level of Effort is detailed in Subtask 6.

7. Annual RASS Report

An Annual Remedial Action System Status Report will be developed which will include an evaluation of the collected information and data for the entire year. The report will detail and summarize the monthly O&M information, along with summary tables, figures and a graphical depiction of the system performance as well as groundwater sampling and analysis. Vapor sampling results will be submitted in the RASS report. The report will be prepared in accordance with the Technical Worksheets or similar guidance documents, developed by the FDEP Drycleaning Solvent Cleanup Program.

Conclusions and recommendations will be made, which will include a summary of modifications made to the system to enhance the recovery rates or decrease system time to achieve targeted goals. 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 detailed in Subtask 7.

8. Utilities for remediation system operation

PSI used the previous utility costs from this system as well as similar equipment at other sites as a basis for the utility costs, as detailed in Level of Effort Subtask 5. We are currently running the system at 100% due to the martial arts facility occupying the former dryclean tenant space.

The Level of Effort for utilities is detailed in Subtask 8.

EXTERNAL MESSAGE

This email originated outside of DEP. Please use caution when opening attachments, clicking links, or responding to this email.

Good Morning Skylar – PSI is pleased to submit the Scope of Work / Cost Estimate / Level of Effort to continue operations for the SVE system at Westwood, Tampa. We did not include groundwater monitoring as we usually do, as the monitoring has been included in the Westwood RAE that we previously submitted (actually, we are waiting to finalize that after you and I get a few things ironed out).

Also, you’ll note that the utilities are higher than last year. Robert had suggested we run the system 100% duty cycle which increased the power costs. Its almost double what it used to be.

Please contact us with any questions!

Dear Ms. Schwed:

Professional Service Industries, Inc. (PSI), an Intertek company, is pleased to provide the proposal contained herein to provide twelve months of remediation system Operation & Maintenance (O&M) services, quarterly email summaries of system operations, and documentation of the remediation system performance with the development of two Remedial Action System Status Reports, for the former Westwood Cleaners located at 4513 Gunn Highway, Tampa, Florida.

e. Collect quarterly system influent and effluent samples, and samples from the three operating SVE wells for analysis by Method TO-15. The FDEP engineering group comments recommended collecting all SVE samples for the first quarter.

f. Document system readings in the site-specific O&M checklist.

g. Quarterly update via email to the FDEP on system operation.

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. Air samples will be collected from the influent and effluent and analyzed by TO-15. A summary of system conditions will be submitted via email to the FDEP each quarter.

The Level of Effort is detailed in Subtask 3.

4. Semi-Annual RASS Report

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 and summarize the monthly O&M information, along with summary tables, figures and a graphical depiction of the system performance. Vapor sampling results will be submitted in the RASS report. The report will be prepared in accordance with the Technical Worksheets or similar guidance documents, developed by the FDEP Drycleaning Solvent Cleanup Program.

Conclusions and recommendations will be made, which will include a summary of modifications made to the system to enhance the recovery rates or decrease system time to achieve targeted goals. 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.
