Dear Brittany:

Geosyntec Consultants, Inc. (Geosyntec) has prepared this Statement of Work (SOW) and Level of Effort (LOE) for six seven months (February 2023 through July August 2023) of operations and maintenance (O&M), of the soil vapor extraction (SVE) system at Colonial/Touch of Class (Site) (Facility ID - ERIC 5222) located in Greenacres, Florida. The SVE system startup occurred 30 November 2020 through 2 December 2020. Monthly O&M has been conducted at the Site since startup, and air and groundwater sampling has been performed in general accordance with Table 6 of the FDEP-approved May 2020 Interim Source Removal (ISR) Work Plan. Geosyntec and the FDEP confirmed on 30 June 2022, that an Access Agreement with the current real property owner of the Colonial/Touch of Class (ERIC_5222) Site has been executed.

This LOE is subdivided into subtasks by quarter. For ease of reference, the major scope elements are outlined below as they will pertain to multiple subtasks in some cases. Each subtask will be outlined separately thereafter.

Changes to the SOW under this task assignment change order (TACO) 1 are shown in red text.

Colonial/Touch of Class – Year 3 O&M LOE (TACO-1)

SCOPE OF WORK ELEMENTS

Monthly SVE System O&M Tasks

Geosyntec personnel will conduct 6 7 monthly O&M visits to the Site beginning in February 2023 (Months 26 to 31 32 of system operation). Note that the January 2023 O&M (Month 25) is included under TA DC002B, which has been approved by FDEP and is in progress. During each O&M visit, Geosyntec personnel will perform the following tasks:

• record vacuum, pressure, and temperature readings at the SVE blower;

• record air flow rates at the blower and five vapor extraction wells (VEWs);

• record vacuum readings at the five VEWs (VEW-1 through VEW-5), MW001 and

VMP01 through VMP05;

• drain fluids accumulated in the moisture separator and disposing of fluids in a 55-gallon drum as investigation derived waste (IDW; water from the moisture separator at the Site has been sampled, analyzed for volatile organic halocarbons [VOHs] and characterized as non-hazardous);

• collect groundwater level measurements from monitoring wells MW001 through

MW007;

• perform required air sampling;

• inspect and clean the equipment compound; and

• perform periodic equipment maintenance activities recommended by equipment manufacturers.

The results of the monthly system O&M activities will be documented in a site-specific O&M log, which will be submitted to the FDEP with the monthly O&M summary emails.

Bump Tests

Bump tests will be conducted during the April 2023 O&M and July 2023 O&M events similar to the bump tests conducted in August 2022 and January 2023. These bump tests will consist of collecting air samples from VEW-1 through VEW-4 and the SVE influent during the March 2023 and June 2023 O&M events prior to shutting down the system. Upon system restart, air samples from the VEW-1 through VEW-4 and the SVE influent will be collected during the April 2023 and July 2023 O&M events. Air samples will be collected with summa canisters and analyzed at a fixed-base laboratory for VOHs by EPA Method TO-15. The results of the bump tests will be provided in the monthly summary emails.

Groundwater sampling

In accordance with Table 6 of the approved May 2020 ISR Work Plan, monitoring wells MW001 and MW002 will be sampled semi-annually (June 2022). Prior to collecting groundwater samples, depth to water measurements will be collected from MW001 through MW007. The groundwater samples will be analyzed by a FDOH NELAC certified laboratory for VOHs using EPA Method 8260. Results of the groundwater sampling event will be documented in the O&M report for the same reporting period.

IDW Generation and Management

Two drums of groundwater IDW are assumed to be generated during monitoring well sampling and moisture collected in the moisture separator. IDW from groundwater monitoring well sampling has been previously characterized as hazardous waste due to the elevated PCE concentrations from one well. IDW from moisture collected in the moisture separator has been previously characterized as non-hazardous waste. Geosyntec requested costs for non-hazardous and hazardous waste from 3 contractors; cost estimates were obtained from Clark Environmental/Enviroserve (quoted non-hazardous and hazardous rates), Erwin Remediation (quoted non-hazardous rate only) and Hepaco (quoted hazardous waste only) are included as Attachment A. Based on the provided estimates, Erwin Remediation has the lowest rate for transportation and disposal (T&D) of 1 drum of non-hazardous liquid ($110) and will be utilized.

For T&D of 1 drum of hazardous liquid, Enviroserve has the lowest rate ($517) and will be utilized.

A VOH sample is required to establish a new profile with the vendor ($73/drum).

Air sampling

In accordance with Table 6 of the approved May 2020 ISR Work Plan, air emissions will be monitored by sampling combined influent air from the VEWs on a quarterly basis at the Site (one air sample per quarter). Combined effluent will not be sampled as the granular activated carbon (GAC) was removed from the SVE system on 11 May 2021 following the 7 April 2021 sampling event that continued to show that VOHs were below the Hazardous Air Pollutant (HAP) criteria requiring GAC treatment. Air samples will be collected with a summa canister and analyzed at a fixed-base laboratory for VOHs by EPA Method TO-15.

Reporting

A Year 3 Semi-Annual O&M Report (following Month 30 [June 2023]) will be prepared to document the results of O&M activities. The O&M reports will include, at a minimum, the following:

• results of laboratory analyses of air samples (tabular and graphical form);

• results of laboratory analyses of groundwater samples (tabular and illustrative form)

• O&M activities performed during the reporting period;

• the calculated mass of PCE (and daughter products, if detected) removed by the SVE system during the reporting period, and cumulative total removed since startup;

• the SVE system hours of operation during the reporting period;

• information regarding the depth to groundwater;

• information regarding any repairs and/or modifications made to the SVE system;

• vacuum ROI data (tabular and illustrative form); and

• recommendations and conclusions pertaining to the continued operation and/or optimization of the SVE system.

Utilities

Monthly electrical utility bills have been estimated at $300 based on the previous year’s average monthly invoices from Florida Power & Light. Telemetry is currently provided by PRM and is available through 31 December 2022. An invoice from PRM for annual telemetry services from 1 January 2023 to 31 December 2023 was received. The cost of telemetry is $109.23 per month with taxes for a total of $1,310.75 (Attachment A). The utilities also include a $20 monthly processing fee for electrical service and a one-time monthly processing fee for annual telemetry.
