This document is a Task Assignment Change Order (TACO-1) issued by the State of Florida Department of Environmental Protection (FDEP) to Geosyntec Consultants, Inc. for operations and maintenance (O&M) work at the Colonial/Touch of Class remedial site (ERIC_5222) located in Greenacres, Palm Beach County, Florida. The change order amends the original Task Assignment DC002E under Contract HW683, with an effective date of December 18, 2024.

The task assignment authorizes twelve months of soil vapor extraction (SVE) system O&M activities conducted from February 2024 through January 2025, with a completion date of April 30, 2025. The TACO-1 increases the total task assignment value from $60,494.37 to $63,510.51, representing a cost increase of $3,016.08. This increase reconciles Work Change Directive #1, which addressed unexpected costs related to a June 2024 system power disconnection and subsequent identification of a nonfunctional battery backup device requiring replacement and remobilization efforts. The scope includes monthly O&M visits, quarterly air sampling, semi-annual and annual groundwater sampling, bump testing, equipment maintenance, and utility costs. Deliverables are invoiced quarterly with the final invoice due March 30, 2025. The contract maintains a fixed unit rate compensation structure with labor hours revised to reflect personnel changes, specifically replacing Senior Professional A. Smith with N. Barnes at comparable labor rates.

This Task Assignment Change Orders authorizes a cost increase and reconciles WCD #1 in accordance with Geosyntec scope of work, cost estimate and schedule received on November 15, 2024. The total increase is $3,016.08

Subtask 3, 4, 5 and 6 TACO-1/WCD-1: During the June O&M event, the system was disconnected from the electrical power. After troubleshooting, it was assumed to be an FPL issue; therefore, O&M could not be performed. Additionally cost to remobilize to the Site for monthly O&M once the power issue is resolved. After the initial troubleshooting and discussions with PRM Filtration, it was determined that the issue is presumed to be a nonfunctional battery backup device. The cost to purchase a new battery backup device and the cost for mobilizing to the Site to resolve the issue have been included.

The Senior Professional (A. Smith) on the original TA is no longer with the firm. Labor hours for Smith are replaced with N. Barnes and his labor rate, which is a similar rate.

The FDEP Project Manager agrees to the scope of work and final cost associated with this Task Assignment. The final cost is $63,510.51 with 320 labor hours.

Subject: 12 Months O&M – Year 4 & 5 - Soil Vapor Extraction System Task Assignment Change Order 1 Colonial/Touch of Class 4552 Lake Worth Road Greenacres, Palm Beach County, Florida 33463 FDEP Facility ID NO. ERIC_5222 Contract HW683, Task Assignment DC002E

Dear Sarah:

Geosyntec Consultants, Inc. (Geosyntec) has prepared this Statement of Work (SOW) and Level of Effort (LOE) for twelve months (February 2024 through January 2025) 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.

TACO-1 revisions to the original SOW are provided in red font; Work Change Directive (WCD) 1 are also reconciled in TACO-1.

Colonial/Touch of Class – Year 4 & 5 (12 Months) O&M SOW 26 October 2023 (15 November 2024)

FR3169E/Colonial TOC (ERIC_5222)_SOW-LOE_HW683_DC002E-1_rev.3 (TACO-1)

SCOPE OF WORK ELEMENTS

Monthly SVE System O&M Tasks

Geosyntec personnel will conduct 12 monthly O&M visits to the Site beginning in February 2024 (Months 38 to 49 of system operation). 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 March 2024 O&M, June 2024 O&M, and September 2024 O&M events. These bump tests will consist of collecting air samples from VEW-1 through VEW-4 and the SVE influent during the February 2024, May 2024, and August 2024 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 March 2024, June 2024, and September 2024 O&M events. Air samples will be collected with summa canisters and analyzed at a fixed-base laboratory for Volatile Organic Hydrocarbons (VOHs) by EPA Method TO-15. The results of the bump tests will be provided in the monthly summary emails.

FR3169E/Colonial TOC (ERIC_5222)_SOW-LOE_HW683_DC002E-1_rev.3 (TACO-1)

Groundwater sampling

In accordance with Table 6 of the approved May 2020 ISR Work Plan, monitoring wells MW001 through MW007 will be sampled annually (February 2024) and monitoring wells MW001 and MW002 will be sampled semi-annually (September 2024). Prior to collecting groundwater samples, depth to water measurements will be collected from MW001 through MW007. The groundwater samples will be analyzed by a Florida Department of Health (FDOH) National Environmental Laboratories Accreditation Conference (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

Four drums of groundwater IDW are assumed to be generated during monitoring well sampling and moisture collected in the moisture separator over the course of twelve months. 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 Erwin Remediation (quoted non-hazardous rates only), Water Recovery (quoted non-hazardous rate only), and EnviroServe (quoted non-hazardous rates only) are included as Attachment A.

Based on the provided estimates, Water Recovery has the lowest rate for transportation and disposal (T&D) of 1 drum of non-hazardous liquid ($105) and will be utilized. For T&D of 1 drum of hazardous liquid, additional quotes will be requested, and a task assignment change order (TACO) will be submitted prior to scheduling T&D of hazardous drum. 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.

FR3169E/Colonial TOC (ERIC_5222)_SOW-LOE_HW683_DC002E-1_rev.3 (TACO-1)

Reporting

A Year 3 Annual O&M Report (following Month 39 [March 2024]) and Year 4 Semi-annual O&M Report (following Month 45 [September 2024]) 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 $350 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 2023. An invoice from PRM for annual telemetry services from 1 January 2024 to 31 December 2024 was received and will be utilized. The cost of telemetry for 2024 is $105.66 per month with taxes for a total of $1,267.95 (Attachment A). The utilities also include a $20 monthly processing fee for electrical service and a one-time monthly processing fee for annual telemetry.
