This fee proposal is based on correspondence with the FDEP and discussions with IRC. As requested by IRC, this fee proposal includes budget to complete two semi-annual monitoring and reporting events for the plume monitoring well network, as well as related consulting services to prepare an annual pollution liabilities evaluation report for identified IRC -owned environmental liabilities and represent IRC during interactions with regulatory agencies. Geosyntec has prepared this proposal (professional services as Exhibit A) as Work Order No. 16 for the 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. PROJECT BACKGROUND 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 will 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. FR0766\XR22024.docx engineers I scientists I innovators Mr. Himanshu H. Mehta, P.E. Geosyntecl5 2 June 2022 consultants Page 2 In consideration of the ongoing natural attenuation processes occurring at the site, the enhancement of these biological processes via the injection of an electron donor was proposed and agreed to in concept by the FDEP in correspondence dated 2 August 2006. In response to FDEP's request and supported by groundwater monitoring results, Geosyntec conducted an injection event in 2017 [Remedial Action Plan Modification Addendum No. 3 (RAPM 3)] to remediate recalcitrant CVOC groundwater impacts in the former source area. Semi-annual performance monitoring associated with bioremediation implementation was conducted from 2017 to 2020. In April 2021, FDEP approved to discontinue performance monitoring associated with RAPM 3 and to discontinue CVOC sample collection at five monitoring well locations where CVOCs had not been detected for at least three consecutive sampling events. Semi-annual groundwater monitoring for CVOCs at 42 monitoring well locations will be conducted in 2022, as well as semi-annual reporting. PROPOSED SCOPE OF WORK The proposed scope of work consists of semi-annual groundwater monitoring and reporting and related activities to be performed on behalf of IRC SWDD at the Former South Gifford Road Landfill. 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 Semi -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 five hours per sampling/reporting event and one hour per month for the project manager (22 hours total), one hour for the senior principal - in -charge, and one hour per month (12 hours total) for the administrative assistant. Phase 2 — Meetings/Re2ulatory Interaction: Under this phase, Geosyntec will prepare for and attend up to one meeting, with IRC SWDD, FDEP, and/or IRC Board of County Commission, 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. FR0766\XR22024.docx engineers I scientists I innovators Mr. Himanshu H. Mehta, P.E. 2 June 2022 Page 3 Geosyntec consultants 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 South Gifford Road Closed Landfill (4701 41St 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 Sampling Activities: Under this phase, Geosyntec will perform 2022 field activities related to the performance monitoring and plume groundwater monitoring. The semi-annual activities will include field preparation, groundwater sampling, and water level measurements. Field preparation activities will include scheduling and staffing, subcontracting, coordination with the analytical laboratory, field equipment preparation, procurement of Passive Diffusion Bag (PDB) samplers, and notifying FDEP and Vero Beach Municipal Airport of the field schedule. Geosyntec will perform the groundwater sampling activities associated with the CVOC plume monitoring well network. Sampling activities in 2022 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 two -person sampling crew and will be performed in general accordance with the FDEP Standard Operating Procedures (SOPs). The proposed summer 2022 field event (tentatively scheduled for the week of 27 June 2022) will include sampling and analyses of groundwater from nine monitoring wells. The summer 2022 field event is budgeted to include one day for groundwater sampling activities and one day for PDB deployment for the next sampling event (total of two [2] field days each with two persons). The proposed winter 2022 field event (tentatively scheduled for December 2022) will include sampling of 42 monitoring wells (31 using PDBs and 11 wells via traditional purging techniques) to collect field water quality parameters. The winter 2022 field event is budgeted to include a total of two (2) days (with two persons) for groundwater sampling activities and PDB deployment for the summer 2023 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 be analyzed in accordance with the sampling plan summarized in the 2021 Annual Groundwater Monitoring Report. Quality control samples are proposed to be collected at a rate of 5% of total samples as required by the most recent FDEP SOPs. FR0766\XR22024.docx engineers I scientists I innovators Mr. Himanshu H. Mehta, F.E. 2 June 2022 Page 4 Geosyntecp consultants Geosyntec will conduct a complete round of groundwater level measurements concurrent with each semi-annual groundwater sampling event (budgeted for one day with two -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 95 wells per event). Due to wet site conditions and difficult access to certain well clusters, costs for rental of a utility phase vehicle are included for one day of groundwater level measurements and one day of sampling per event (4 total days). It is anticipated that purge water (investigation -derived waste [IDW]) will be containerized in 55 -gallon polyethylene drums and temporarily staged on Site for characterization prior to removal and disposal. Costs are included herein for purchase of one 55 -gallon polyethylene drum and for one-half day of drum disposal oversight for one person. Overall, for field activities, budget has been included for six field days with two persons, mobilization time for field personnel, and associated field expenses for sampling. Geosyntec will provide oversight for a contractor to clear brush in an approximate 6 feet radius around select well clusters in conjunction with the winter 2022 groundwater sampling event to maintain access to well clusters. Costs are included for one day oversight (with one person) and for subcontractor costs. Phase 5 — Data Evaluation and Semi -Annual Reporting: Under this phase, Geosyntec will perform data evaluation activities and reporting. The reporting includes preparation of one summer 2022 report (simplified format) and one winter 2022 report for submittal to FDEP. The summer 2022 report will be a letter report with attachments, including a monitoring well location map and tables of the field and laboratory results. Data evaluation activities for the summer 2022 report will include database management, screening results against applicable regulatory criteria, and summary data table preparation. This report is due to FDEP by 31 July 2022. The winter 2022 report 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 winter 2022 annual 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. Historical data summaries will be included for monitoring wells recommended for removal from the monitoring plan. FR0766\XR22024.docx engineers I scientists I innovators Mr. Himanshu H. Mehta, P.E. 2 June 2022 Page 5 Geosyntec° consultants The draft summer and winter 2022 reports will be submitted to IRC SWDD for review prior to submittal to FDEP. Each final report will be signed and sealed by a Florida registered professional engineer or geologist. SCHEDULE The semi-annual groundwater sampling events will be tentatively conducted in June and December 2022 as described herein. Reports will be submitted to FDEP to meet required deadlines. BUDGET ESTIMATE A budget estimate for the scope of work outlined in Phases 1 through 6 of this proposal is summarized in the following table, and a detailed budget estimate is provided as Attachment A. The budget estimate presented in this proposal is based on Geosyntec's understanding of the project requirements, our experience gained from executing similar phases for SWDD since 2002 at the Site, and experience with groundwater monitoring and reporting activities at similar facilities. The estimated budget for 2022 compared to 2021 is approximately 7% less due to efficiencies gained from previous field and reporting events. Geosyntec will not exceed the budget estimate without prior approval and written authorization from IRC SWDD.
