This scope and fee proposal is based on correspondence with the FDEP and discussions with IRC. As requested by IRC, this fee proposal includes budget for the following activities: • Complete two semi-annual monitoring events for the plume monitoring well network, • Provide related consulting services, • Represent IRC during interactions with regulatory agencies, • Prepare an annual pollution liabilities evaluation report for identified IRC -owned environmental liabilities, and • Prepare an annual groundwater monitoring report summarizing semi-annual sampling activities and results. Geosyntec has prepared this proposal (professional services as Exhibit A) as Work Order No. 6 for the 2023 Continuing Contract Agreement for Professional Services between IRC SWDD and Geosyntec. The remainder of this letter provides an overview of the project background, a description of the proposed scope of work, a budget estimate, and a discussion of the schedule for accomplishment of the work described herein. FR0766\XR24015.docx engineers I scieritists I innovators Mr. Himanshu H. Mehta, P.E. 22 April 2024 Page 2 PROJECT BACKGROUND Geosyntec consultants As part of the long-term monitoring activities for the identified CVOC plume associated with the South Gifford Road Landfill, a network of monitoring wells require sampling on an annual or semi-annual basis to: (i) confirm that the CVOC plume is not migrating by monitoring the lateral and vertical extent; (ii) evaluate the impact of source and dissolved plume bioremediation to assess CVOC plume centerline concentrations over time; and (iii) assess the impact of biological and physical natural attenuation processes on CVOC plume degradation. Geosyntec conducted previous bioremediation injection events in 2008, 2009, 2012, and 2017 to remediate recalcitrant CVOC groundwater impacts in the downgradient biobarriers and in the former source area. Groundwater monitoring results in 2023 suggested that the plume monitoring well network could be reduced to account for plume shrinkage since the previous 2017 bioremediation injection. In the 2023 Annual GMR, Geosyntec recommended to remove 16 monitoring wells from the 2024 sampling and analysis plan, reducing the number of monitoring wells sampled from 42 to 26, a 38% decrease. Geosyntec also recommended to change the reporting frequency from semi-annual to annual. FDEP approved these recommendations to reduce sampling and reporting frequency in an approval letter dated 18 March 2024. PROPOSED SCOPE OF WORK For the purpose of budgeting, the scope of work has been divided into the following phases: • Phase 1 — Project Management, • Phase 2 — Meetings/Regulatory Interaction, • Phase 3 — Annual Pollution Remediation Liabilities Evaluation, • Phase 4 — Semi -Annual Sampling Activities, and • Phase 5 — Data Evaluation and Annual Reporting. The remainder of this section presents a general description of the activities to be performed in each phase. Phase 1 — Proiect Management: Under this phase, Geosyntec will perform project planning and management responsibilities, such as correspondence with IRC SWDD and FDEP, invoice review, project coordination, and project administration. The budget includes two hours per month for the project manager (24 hours total) and one hour per month (12 hours total) for the project administrator. FR0766\XR24015.docx engineers ( scientists I innovators Mr. Himanshu H. Mehta, P.E. 22 April 2024 Page 3 Geosyntec° consultants Phase 2 — Meetinas/Reeulatory Interaction: Under this phase, Geosyntec will prepare for and attend up to one meeting, with IRC SWDD, FDEP, and/or IRC Board of County Commissioners, as necessary. It has been assumed that this meeting will be in person. Also, under this phase, four hours has been included for the Senior Principal -in -charge to provide ongoing support to IRC SWDD related to interaction and negotiation with FDEP. Phase 3 —Annual Pollution Remediation Liabilities Evaluation: As requested by IRC SWDD, under this phase, Geosyntec will prepare the annual environmental liability evaluation. This document is prepared annually in response to Governmental Accounting Standards Board Statement No. 49 (GASB No. 49), Accounting and Financial Reporting for Pollution Remediation Obligations, which requires the inclusion and calculation of pollution remediation obligations. The objective of GASB No. 49 is to enhance the usefulness and comparability of pollution remediation obligation information reported by state and local governments. It has been assumed that the report will include evaluation of two sites, including Former South Gifford Road Landfill (470141' Street) and Former Premier Citrus Property (375 82nd Street). In addition, two hours have been included for a Florida -registered Professional Engineer to conduct an independent review of the liability evaluation. Phase 4 — Semi -Annual Samaline Activities: Under this phase, Geosyntec will perform 2024 routine semi-annual groundwater monitoring. The semi-annual activities will include field preparation, water level measurements, and groundwater sampling. Field preparation activities will include scheduling and staffing, subcontracting, coordination with the analytical laboratory, field equipment preparation, procurement of Passive Diffusion Bag (PDB) samplers, coordination with Vero Beach Municipal Airport for water level measurement, and notifying FDEP of the field schedule. Geosyntec will perform the groundwater sampling activities associated with the CVOC plume monitoring well network. Sampling activities in 2024 will be completed with a combination of PDB samplers, as a cost -savings measure, and traditional low -flow sampling techniques, to evaluate groundwater quality and the occurrence of intrinsic biodegradation. PDBs are anticipated to be purchased from EON Products, one of the few suppliers of this type of passive sampling device. Groundwater sampling activities will be executed using a 2 -person sampling crew and will be performed in general accordance with the FDEP Standard Operating Procedures (SOPS). The proposed Summer 2024 field event (tentatively scheduled for June 2024) will include sampling and analyses of groundwater from 7 monitoring wells. The Summer 2024 field event is budgeted to include 1 day with 2 people for groundwater sampling and PDB deployment activities for the next sampling event. The proposed Winter 2024 field event (tentatively scheduled for December 2024) will include sampling of 26 monitoring wells (19 using PDBs and 7 wells via traditional purging techniques) to collect field water quality parameters. The Winter 2024 field event is budgeted to include a total of 3 days (with 2 people) for groundwater sampling activities and PDB deployment for the Summer 2025 field event. Consistent field documentation and field protocols will be utilized to develop reliable data to support the natural attenuation evaluation for the groundwater plume. The groundwater samples will FR0766\XR24015.docx engineers I scientists I innovators Mr. Himanshu H. Mehta, P.E. 22 April 2024 Page 4 Geosyntec consultants be analyzed in accordance with the sampling plan summarized in the 2023 Annual Groundwater Monitoring Report (GMR). Quality control (QC) samples are proposed to be collected at a rate of 5% of total samples as required by the most recent FDEP SOPS, resulting in 2 QC samples annually. Geosyntec will conduct a round of groundwater level measurements in accordance with the sampling plan summarized in the 2023 Annual GMR concurrent with each semi-annual groundwater sampling event (budgeted for 1 day with 2 -person field team for each event). Depth to groundwater measurements will be recorded to the nearest 0.01 -ft in each monitoring well, including existing monitoring wells and applicable City of Vero Beach wells (assumed up to 60 wells per event). Overall, for field activities, budget has been included for 6 field days with 2 persons, mobilization time for field personnel, and associated field expenses for sampling. Due to wet site conditions and difficult access to certain well clusters, costs for rental of a utility phase vehicle are included for 1 day of groundwater level measurements and 1 day of sampling per event (4 total days). It is anticipated that purge water (investigation -derived waste [IDW]) will be containerized in a 55 - gallon polyethylene drum and temporarily staged on Site for characterization prior to removal and disposal. Costs are included herein for purchase of one 55 -gallon polyethylene drum, drum removal and disposal by a licensed subcontractor, and for 4 hours of drum removal oversight for 1 person. Brush clearing by a contractor is necessary on a biannual basis to clear overgrowth and maintain access to the well clusters and was last performed at the Site in October 2022. In 2024, Geosyntec will provide oversight for a contractor to clear shrubs, vines, and tall grass in an approximate 6 feet radius around select well clusters using a track loader with mower deck. Costs are included for one day oversight (with one person) and for subcontractor costs. Phase 5 — Data Evaluation and Annual Reporting: Under this phase, Geosyntec will perform data evaluation activities and reporting. The reporting includes preparation of the 2024 Annual GMR for submittal to FDEP. The 2024 Annual GMR will be consistent with the groundwater monitoring reports historically submitted to FDEP for this Site and the data evaluation activities will include database management, screening results against applicable regulatory criteria, GIS figure preparation, time trend analyses, and/or statistical data analyses. The report will be supported by attachments containing Chain -of - Custody sheets, field notes and observations, water sampling logs, maps, graphs, analytical results, quantitative statistical evaluation, and other applicable materials. As part of the statistical analysis, trend analysis graphs showing temporal concentrations of constituents and a summary of the Mann - Kendall statistics will be included to identify increasing, decreasing, or no trends in groundwater constituent concentrations. The draft 2024 Annual GMR will be submitted to IRC SWDD for review FR0766\XR24015.docx engineers I scientists I innovators Mr. Himanshu H. Mehta, P.E. 22 April 2024 Page 5 Geosyntec consultants prior to submittal to FDEP. The final report will be signed and sealed by a Florida -registered Professional Engineer or Geologist.
