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, monitoring well maintenance and brush clearing, 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. CCNA2018 WO No. 1 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 FR0766\XR18011 engineers I scientists I innovators Mr. Himanshu H. Mehta, P.E. 30 April 2018 Page 2 Geosyntec consultants CVOC plume centerline concentrations over time; and (iii) assess the impact of biological and physical natural attenuation processes on CVOC plume degradation. 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 (RAPM3)] to remediate recalcitrant CVOC groundwater impacts in the former source area. Semi-annual performance monitoring associated with bioremediation implementation is ongoing at monitoring well GR-MW37B and conducted concurrently groundwater monitoring of the plume monitoring well network. 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 tasks: • Task 1 — Project Management; • Task 2 — Meetings/Regulatory Interaction; • Task 3 — Annual Pollution Remediation Liabilities Evaluation; • Task 4 — Semi -Annual Sampling Activities; • Task 5 — Monitoring Well Maintenance; • Task 6 — Brush Clearing Activities; and 0 Task 7 — Data Evaluation and Semi -Annual Reporting. The remainder of this section presents a general description of the activities to be performed in each task. Task 1 — Proiect Manaeement: Under this task, 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 ten hours per sampling/reporting event for the project manager, two hours for the principal -in -charge, and two hours for the administrative assistant. FR0766\XR 18011 engiI7eers I scientists I innovators Mr. Himanshu H. Mehta, P.E. 30 April 2018 Page 3 Geosynteccl consultants Task 2 — Meetings/Regulatory Interaction: Under this task, Geosyntec will prepare for and attend up to two meetings, with IRC SWDD, FDEP, and/or IRC Board of County Commission, as necessary. It has been assumed that one of these meetings will be in person and one meeting will be by conference call. Also, under this task, six hours has been included for the principal -in -charge to provide ongoing support to IRC SWDD related to interaction and negotiation with FDEP. Task 3 — Annual Pollution Remediation Liabilities Evaluation: As requested by IRC SWDD, under this task, 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 41" Street) and Old Administration Building (1840 25th Street). In addition, two hours have been included for a Florida registered professional engineer to conduct an independent review of the liability evaluation. Task 4 — Semi -Annual Sampling Activities: Under this task, Geosyntec will perform 2018 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. Performance monitoring well MW -37B associated with the RAPM3 implementation is included in the semi-annual sampling plan for analysis of bioremediation performance parameters, including dissolved gasses, total organic carbon, and dechlorinating microbial concentration. Geosyntec will perform the groundwater sampling activities associated with the CVOC plume monitoring well network. Sampling activities will be completed with a combination of PDB samplers and traditional low -flow sampling techniques. PDBs are anticipated to be purchased from EON Products, one of the few suppliers of this type of passive sampling device. Two PDB harnesses will be purchased from EON Products for monitoring wells GR-MW02C and GR- MW22CCR. 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 2018 field event (tentatively scheduled for June) will include sampling of nine monitoring wells (three wells using PDBs and six wells with traditional sampling techniques). The summer 2018 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 field days each with two persons). The proposed winter 2018 field event (tentatively scheduled for FR0766\XR18011 engineers I scientists I innovators Mr. Himanshu H. Mehta, P.E. 30 April 2018 Page 4 Geosyntec consultants December) will include sampling of 47 monitoring wells (37 wells using PDBs and ten wells with traditional sampling techniques). The winter 2018 field event is budgeted to include a total of three days (with two persons) for groundwater sampling activities and PDB deployment for the summer 2019 sampling 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 2017 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. Geosyntec will conduct a complete round of groundwater level measurements coincident 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 90 wells per event). 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 two 55 -gallon polyethylene drums and oversight of drum disposal concurrent with one of the sampling events. Overall, budget has been included for six field days with a two -person team (i.e., 12 man days) and associated field expenses for sampling. Task 5 — Monitoring Well Maintenance: A monitoring well inventory was conducted by Geosyntec personnel in December 2017 to document maintenance needs, including top of casings that had shifted above well completions, new well plugs, and/or new manhole lids. Based on observations, maintenance activities are necessary, as discussed with IRC, to repair well pads at three cluster locations, GR-MW13, GR-MW27, GR-MW32. Geosyntec will provide oversight for a subcontractor to repair tops of casings and replace well pads. A Florida -licensed surveyor will survey the repaired monitoring wells and performance monitoring well GR-MW37B to identify the location and relevant elevation information (e.g., top of casing, ground surface). Monitoring well maintenance will be performed prior to the summer 2018 semi-annual groundwater monitoring event. Task 6 — Brush Clearing Activities: During the monitoring well inventory conducted by Geosyntec personnel in December 2017, approximately 20 well clusters were noted to be overgrown by brush or tall grass impeding access for sample collection. Geosyntec will provide oversight for a contractor to clear brush and mow undergrowth in an approximate 6 feet radius around select well clusters. Brush clearing activities will be performed prior to the summer 2018 semi-annual groundwater monitoring event. FR0766\XR18011 engineers I scientists I innovators Mr. Himanshu H. Mehta, P.E. 30 April 2018 Page 5 Geosynte& considtants Task 7 — Data Evaluation and Semi -Annual Reporting: Under this task, Geosyntec will perform data evaluation activities and reporting. The reporting includes preparation of one summer 2018 report (simplified format) and one winter 2018 report for submittal to FDEP. The summer 2018 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 2018 report will include database management, screening results against applicable regulatory criteria, and summary data table preparation. This report will be prepared following the June groundwater sampling event. The winter 2018 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 2018 annual report will be supported by attachments containing Chain -of -Custody sheets, field notes and observations, water sampling logs, maps, graphs, analytical results, and any other applicable materials. In addition to the information outlined above (which has been provided historically in groundwater monitoring reports for the Site), this report will include a more rigorous quantitative statistical evaluation of the CVOC results to support the"possible reduction in the quantity and frequency of the sampling activities. 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. This report will be prepared following the December groundwater sampling event. The draft summer and winter 2018 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 monitoring events will be tentatively conducted in June and December 2018 as described herein. Reports will be submitted to FDEP to meet required deadlines.
