Mehta, P E. Managing Director Solid Waste Disposal District Indian River County 1325 74th Avenue SW Vero Beach, Florida 32968 Subject: Proposal to Provide One Year of Groundwater Monitoring/Reporting and Related Consulting Services Former South Gifford Road Landfill Vero Beach,Indian River County,Florida Dear Mr. Mehta: Geosyntec Consultants (Geosyntec) is pleased to submit this letter proposal to the Indian River County (IRC) Solid Waste Disposal District (SWDD) to provide professional services for Florida Department of Environmental Protection (FDEP)-required activities associated with continued implementation of the groundwater monitoring for the chlorinated volatile organic compound (CVOC) plume at the Former South Gifford Road Landfill located in Vero Beach, Indian River County, Florida (Site). 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 a Remedial Action Plan Modification (RAPM) Addendum No. 3, 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 1) as Work Order No. CCNA-2014 WO No. 4 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 XR 16005\XR 16001.docx engineers I scientists I innovators Mr. Himanshu H Mehta, P.E. GeOSynteC"' 17 February 2016 consultants Page 2 to assess 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. A RAP Modification (RAPM) was submitted to the FDEP outlining the injection of an electron donor, Emulsified Oil Substrate (EOS®), in May 2007. Geosyntec implemented the RAPM activities in April through June 2008, as documented in the RAPM Implementation Report submitted to FDEP as Appendix A to the June 2008 Semi-Annual Groundwater Monitoring Report. RAPM Addendum implementation, which included bioremediation implementation in the former source area, was completed in June and July 2009 and documented in the July 2009 RAPM Addendum Implementation Report. The ongoing semi-annual groundwater monitoring activities have documented the success of this approach. EOS® is designed to provide a carbon source to the indigenous bacteria for up to approximately three years. In response to FDEP's request dated 3 May 2011 and supported by groundwater monitoring results, a RAPM Addendum No. 2 was prepared and presented an electron donor injection plan to address recalcitrant chlorinated volatile organic compound (CVOC) impacts in the former source area and to redone the two downgradient biobarriers, which are serving as a permeable reactive barrier (PRB) to treat a portion of the dissolved plume. Groundwater monitoring conducted at the Site suggests that it is appropriate to plan for an additional injection in 2016. 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 —Prepare RAPM Addendum No. 3; • Task 4—Annual Pollution Remediation Liabilities Evaluation; • Task 5 —Semi-Annual Sampling Activities; and • Task 6—Data Evaluation and Semi-Annual Reporting. The remainder of this section presents a general description of the activities to be performed in each task. XR 16005\XR 16001.docx engineers I scientists I innovators Mr. Hu»anshu H. Mehta, P.E. Geosyntec"' 17 February 2016 consultants Page 3 Task I — Project Management: 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 eight hours per sampling/reporting event and two hours related to the RAPM Addendum for the project manager and two hours for the principal-in-charge. 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 with be attended by conference call. Also, under this task, four hours has been included for the project manager to provide ongoing support to IRC SWDD related to interaction and negotiation with FDEP. Phase 3 — Prepare RAPM Addendum No. 3: Under this task, in response to FDEP's request dated 21 September 2015 and supported by groundwater monitoring results, Geosyntec will prepare RAPM Addendum No. 3 to propose a focused injection of EOS® (or equivalent electron donor) to address CVOC impacts in the vicinity of GR-MW30B, based upon the apparent breakdown of the electron donor last injected in February 2012 (based upon TOC results). It is recommended that the injection activities include a buffering agent to counter the low pH measurements recorded in GR-MW26B and GR-MW30B. (Note: Budget has not been included for the implementation of additional bioremediation injection activities that will be proposed in the RAPM). Task 4 —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 41St Street) and Old Administration Building (1840 25'h Street). Task 5—Semi-Annual Sampling Activities: Under this task, Geosyntec will perform 2016 field activities related to the 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. X R 16005\XR 16001.docx engineers I scientists I innovators Mr Himanshu H Mehta, P.E. GeOSynteCO 17 February 2016 consultants Page 4 Geosyntec will perform the groundwater sampling activities associated with the CVOC plume monitoring wells. 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. This effort is anticipated to be completed by two people within one day during each of the semi-annual sampling events to save an additional mobilization (e.g. the PDBs to be sampled during the winter 2016 sampling event will be deployed during the summer 2016 event after sampling activities are completed). 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 annual field event will be conducted in summer 2016 (tentatively in June) and will include sampling of 49 monitoring wells (39 wells using PDBs and 10 wells with traditional sampling techniques). The annual field event is budgeted to include three days for groundwater sampling activities and one day for PDB deployment for the next sampling event (total of four field days). The proposed semi-annual field event will be conducted in winter 2016 (tentatively in December) and will include sampling of 28 monitoring wells (25 wells using PDBs and 3 wells with traditional sampling techniques). The semi-annual field event is budgeted to include two days for groundwater sampling activities and one day for PDB deployment for the next sampling event (total of three days). 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 December 2015 Semi-Annual Groundwater Monitoring Report. 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 88 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 nine field days with a two-person team (i.e., 18 man days) and associated field expenses for sampling, plus four hours for IDW management. XR 16005\XR 16001.docx engineers I scientists I innovators Mr Himanshu H. Mehta, P E Geosyntec" 17 February 2016 consultants Page 5 Task 6 — Data Evaluation and Semi-Annual Reporting: Under this task, Geosyntec will perform data evaluation activities and reporting. The reporting includes preparation of one semi- annual report (simplified format) and one annual report for submittal to FDEP. The annual 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. This report will be prepared following the summer groundwater sampling event. The 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. The semi-annual 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 semi-annual report will include database management, screening results against applicable regulatory criteria, and summary data table preparation. This report will be prepared following the fall/winter groundwater sampling event. The draft annual and semi-annual reports will be submitted to IRC SWDD for review prior to submittal to FDEP. Each final semi-annual report will be signed and sealed by a Florida registered professional engineer or geologist. SCHEDULE Geosyntec will conduct the groundwater monitoring and reporting activities on a semi-annual basis as described herein. The semi-annual groundwater monitoring events will be tentatively conducted in June and December 2016. The draft RAPM Addendum No. 3 will be submitted to IRC SWDD for review within 60 days of receipt of authorization from IRC. BUDGET ESTIMATE A budget estimate for the scope of work outlined in Tasks 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 tasks for SWDD since 2002 at the Site, and experience with groundwater monitoring and reporting activities at similar facilities. Geosyntec will not exceed the budget estimate without prior approval and written authorization from IRC SWDD.
