Mehta, P.E. Managing Director Solid Waste Disposal District Indian River County 1325 74th Avenue SW Vero Beach, Florida 32968 Subject: Proposal to Implement FDEP-Approved Remedial Action Plan Modification (RAPM)Addendum No.3 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 associated with implementation of Florida Department of Environmental Protection (FDEP)-approved RAPM Addendum No.3 related to the recalcitrant chlorinated volatile organic compound(CVOC) plume at the Former South Gifford Road Landfill located in Vero Beach, Indian River County, Florida. As requested by IRC, this fee proposal includes budget to implement activities required by FDEP as outlined in the RAPM Addendum No. 3 dated 31 May 2016 and approved by FDEP in a letter dated 15 July 2016. Geosyntec has prepared this proposal (professional services as Exhibit 1)as Amendment No.2 to existing Work Order No.4 for the Continuing Contract Agreement for Professional Services between IRC SWDD and Geosyntec. The remainder of this letter provides a project background, an overview of 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 Remedial activities have been completed at the Site historically r p s y to address CVOC concentrations identified in groundwater as outlined in the FDEP-required Remedial Action Plan (RAP) for the Site, as well as subsequent RAP Modifications (RAPMs). Source removal activities were completed in 2004 and subsequently bioremediation activities were implemented. Performance monitoring data has been collected during subsequent semi-annual groundwater monitoring events and the results of these monitoring events have been included within the semi-annual groundwater XR16044-Gifford RAPM3 Imp engineers I scientists I innovators Mr. Himanshu H. Mehta, P.E. 28 December 2016 Page 2 monitoring reports provided to the FDEP. As outlined in the RAPM Addendum No. 2, it was anticipated at the time that additional bioremediation injection activities would likely be warranted in 3 to 5 years as the injected electron donor was depleted. Trichloroethene (TCE) concentrations in the former source area (GR-MW30B) have fluctuated following the injection activities associated with RAPM Addendum No. 2, with semi-annually reported concentrations above the Groundwater Cleanup Target Level (GCTL) ranging from 124 to 3,150 micrograms per liter (µg/L) since June 2014, indicating that while groundwater concentrations at the Site have significantly improved(with concentrations lower by several orders of magnitude over pre-source removal concentrations), there may be recalcitrant CVOC mass in the vicinity of the former source area that continues to contribute CVOCs to groundwater. A RAPM3, requested by FDEP in correspondence dated 21 September 2015, was approved by FDEP on 15 July 2016 and proposed a follow up injection of electron donor and dechlorinating microbial culture in the former source area. Former source area pre-injection investigation activities, including collection of discrete groundwater samples via direct push technology (DPT) and collection of groundwater samples from site monitoring well injection wells, were conducted in July 2016 and resulted in a refined target treatment area within the former source area. PROPOSED SCOPE OF WORK The proposed scope of work includes the activities required to implement the FDEP-approved RAPM Addendum No. 3, including the procurement of injection amendment and drilling subcontractor and performance of the injection activities. The remainder of this letter provides details regarding the proposed scope of work and a budget estimate to accomplish the work described herein. For the purpose of budgeting,the scope of work has been divided into the following four phases: • Phase 1 —Project Management; • Phase 2—Meetings/Regulatory Interaction; • Phase 3 —Injection Activities; and • Phase 4—UIC and Performance Monitoring and Reporting. The remainder of this section presents a general description of the activities to be performed in each phase. Phase 1 —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. XR16044-Gifford RAPM3 Imp engineers I scientists I innovators Mr. Himanshu H. Mehta, P.E. 28 December 2016 Page 3 Phase 2—Meetings/Regulatory Interaction Under this task, Geosyntec will prepare for, and attend a project meeting with FDEP, as requested by IRC SWDD. It has been assumed that two Geosyntec personnel will attend the meeting, which will be held at the IRC SWDD office. A powerpoint presentation will be prepared for use during the meeting. Phase 3—Iniection Activities Under this task, Geosyntec will implement the proposed injection activities, as outlined in the FDEP-approved RAPM Addendum No. 3 and detailed information provided to IRC SWDD via email on 28 December 2016 regarding the proposed injection approach and refined treatment area. These activities will include monitoring well installation,procurement of injection amendment and drilling subcontractor and performance of the injection activities. It has been assumed that the injection activities can be completed in five field days(one day for onsite field prep,three days for monitoring well installation and injection activities, and one day for breakdown). IDW will be containerized and staged on-site for proper disposal. Underground Injection Control (UIC) monitoring is required after injecting remedial fluids into the aquifer according to Chapter 62-528 of the Florida Administrative Code (F.A.C.). UIC monitoring will be included with the semi-annual sampling events until criteria are met. Performance monitoring of CVOCs and total organic carbon will continue to be included as part of the semi-annual sampling events. Budget for UIC and performance monitoring will be conducted concurrently with semi-annual groundwater monitoring at the Site as a cost-savings measure. Budget has not been included herein for these activities at this time. Phase 4—Reporting Implementation of RAPM Addendum No. 3 will be summarized in the semi-annual groundwater monitoring report that follows completion of the implementation activities. A limited budget has been included herein to incorporate a description of these activities and a summary of the results into the currently authorized semi-annual groundwater monitoring reports. SCHEDULE Geosyntec will initiate project scheduling and implementation activities within two weeks of receipt of notice to proceed from the County. The final field schedule will be based on subcontractor availability and the delivery schedule for the injection materials. We anticipate that the field activities will tentatively be conducted in February 2017. A description of the well installation and dosing activities will be included in future semi-annual groundwater monitoring report(s).

Mehta, P.E. 28 December 2016 Page 4 BUDGET ESTIMATE A budget estimate for the scope of work outlined in Phases I through 4 of this proposal is summarized in the following table, and a detailed budget estimate is provided as Exhibit 1. 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 remediation activities at similar facilities. Geosyntec will not exceed the budget estimate without prior approval and written authorization from IRC S WDD.
