Mr. Benjamin Aoki Environmental Specialist II Florida Department of Environmental Protection Waste Site Cleanup Section 2600 Blair Stone Road, MS 4520 Tallahassee, FL 32399-2400
Subject: Operation and Maintenance and Groundwater Monitoring Proposal Mango Cleaners 11744 Highway 574, Seffner, Hillsborough County, FL
ERIC_4715
Dear Mr. Aoki:
CDM Smith Inc. (CDM Smith) is pleased to respond to the Florida Department of Environmental Protection (FDEP) Task Assignment Request to provide Operation and Maintenance (O&M) and groundwater monitoring services for the Mango Cleaners site under Contract Number HW681. Our project understanding, scope of work, and project schedule are described below, while the cost estimate is also attached.
Project Understanding The former dry-cleaning facility is currently vacant and is in a small strip mall. A revised Interim Source Removal Plan (ISRP) for the site was submitted in April 2020 and a Remedial Action Startup Report was submitted in May 2022. The required O&M activities for this task assignment were taken from the 2020 ISRP and the schedule is based on work completed during remedial action startup.
O&M services are required for a soil vapor extraction (SVE) system that consists of three vapor extraction (VE) wells, SVE blower, air injection blower, moisture separator, and a granulated activated carbon (GAC) vapor treatment drum. Two additional MAGS™ wells are also connected to the system that have been used for both VE and air injection. All VE wells are in indoor locations. SVE operations began on October 20, 2021.
SVE system influent air samples are sampled on a quarterly basis and submitted for laboratory analysis by United States Environmental Protection Agency (EPA) Method TO-15 for volatile organic halocarbons.
Air samples are collected from the three operating SVE wells (VE001, VE002, and VE003) on an annual basis and submitted for laboratory analysis by EPA Method TO-15. Operation and Maintenance (O&M) site visits are completed monthly, and O&M reports are submitted quarterly.
Groundwater monitoring is being completed annually at five monitoring wells for volatile organic halocarbons (VOHs). Semiannual and Annual Remedial Action Status Reports (RASR) are submitted. The annual sampling event would be performed in January 2025.
Mr. Benjamin Aoki
Scope of Work This cost proposal covers SVE system O&M and groundwater monitoring for one year, beginning in December 2024 and ending in November 2025.
Subtask 1 – Project Management Project management activities performed under this task consist of administrative functions required to maintain the project schedule, adhere to budget, and deliver the quality of the work products defined by CDM Smith's quality standards. We will prepare and submit invoices upon approval of each deliverable or milestone completion.
Project Kickoff and Progress Meetings CDM Smith expects to have a kickoff meeting or telephone conference with the FDEP to review the status of the project and address FDEP comments regarding the Task Assignment. CDM Smith will prepare meeting agendas and notes as part of this task.
Project Quality Technical Review CDM Smith’s Quality Management System guidelines will be followed. Internal quality reviews will be conducted on plans and on investigation findings and reports.
Project Status Reports CDM Smith’s Project Manager will prepare and submit monthly status reports to accompany each invoice throughout the duration of this project. The Project Manager will also discuss the status of the project with the FDEP on a bi-weekly basis until the project is complete.
Subtask 2 – Groundwater Monitoring The groundwater monitoring requirements for the site were identified in the 2020 ISRP. CDM Smith will complete the groundwater sampling event in January 2025. The required laboratory analyses and the wells included in the monitoring program are listed in the attached Table 1.
CDM Smith will collect water levels from all site monitoring wells during the sampling event. Purging and sampling will be in accordance with FDEP’s Standard Operating Procedures for Groundwater Sampling, FS 2200, and will be collected using low-flow techniques with a peristaltic pump and dedicated polyethylene tubing. A YSI-556 multi-parameter probe and a turbidimeter will be used to collect water quality indicator parameters including dissolved oxygen, pH, conductivity, oxidation reduction potential, temperature, turbidity. The instrumentation will be properly calibrated and recorded. All purge water will be contained in a drum for characterization and disposal as nonhazardous investigation-derived waste (IDW). CDM Smith assumes that one IDW drum will require disposal under Subtask 4.
Deliverables: Laboratory Reports, field notes, and updated tables for the groundwater sampling event.
Subtasks 3, 4, 5 and 6 – Quarterly SVE System Operation and Maintenance O&M Site visits will be completed monthly, and the following work will be completed during each visit.
System operation and alarm status and blower run time.
Moisture separator liquid volume.
System vacuums and velocity/flow rate at blower, before / after GAC (if applicable), and after moisture separator.
Blower oil changes (when applicable) based on manufacture recommendations.
SVE well vacuum/pressure and flow rate.
Total organic vapors measured with a photoionization detector from operating SVE wells, system influent, and system effluent.
Water levels from monitoring wells MW-1, MW-2, MW-3, MW-4, MW-5, MW-6, DW-1 and DW- 2.
Adjust vacuums and injection pressures on the SVE wells to optimize the SVE system performance.
The information will be consistently recorded in the field on pre-prepared forms.
SVE system influent samples will be collected quarterly for laboratory analysis by Method TO-15. The required laboratory analyses and the SVE included in the monitoring program are listed in the attached Table 1.
Following the completion of Subtasks 3 and 4 O&M activities, CDM Smith will prepare a Semiannual RASR and an Annual RASR will be prepared following the completion of Subtask 5 and 6 activities. The reports will summarize the history of the Site, all fieldwork completed by CDM Smith, field and laboratory data, conclusions, and recommendations. Additional elements of the reports will include the following:
Figures depicting site conditions.
Figures depicting groundwater data and estimated extent of impact.
Groundwater elevation contour map.
Tables summarizing field and analytical data.
Groundwater sampling logs and field equipment calibration records.
Laboratory analytical reports and chain of custody documentation.
Waste disposal manifests and weigh tickets.
Deliverables: Semiannual and Annual Remedial Action Status Reports
Subtasks 7, 8, 9, and 10 – Utilities CDM Smith will provide utilities for the SVE system and assume $700 per month including administrative costs.
Deliverable: Utilities Handling Fee, receipt of 3 months of utility invoices for each Subtask (Cost Plus Fixed Fee)
Subtask 11 – Rebound Evaluation The Annual RASR under Task Assignment DC022B was submitted in August 2024 and is still awaiting FDEP technical approval. The Rebound Evaluation associated with the Annual RASR dated August 2024 will be conducted in this Task Assignment under Subtask 11.
At FDEP’s direction a modified Rebound Evaluation will be conducted in the first month of operation under this Task Assignment. The system has been off since the October 2024 O&M event; therefore, pre-shutdown samples will not be collected. CDM Smith will turn the system on, purge one pore volume of soil vapor, and then collect soil vapor samples from VE001, VE002, VE003 and system influent prior to shutting the system off until Rebound Evaluation results and a path forward can be discussed with the FDEP. CDM Smith will summarize the Rebound Evaluation and conclusions in a technical memo to FDEP.
Deliverable: Rebound Evaluation Technical Memo including field documentation, updated analytical tables, and conclusions.
Subcontractors Subcontracted services are required for IDW disposal. Rates for IDW removal and disposal were previously requested for HW681 from Erwin Remediation, Enviroserve (formerly Clark Environmental), and Hepaco. Erwin Remediation was the lowest cost and has been selected as the IDW disposal subcontractor for this project as shown in Attachment A
Assumptions CDM Smith will communicate with the FDEP in a timely manner if schedule delays are encountered and will prepare necessary paperwork for change orders.
