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, represent IRC during interactions with regulatory agencies, and dismantle the On -Site Interim Pump & Treat (IP&T) System. Geosyntec has prepared this proposal (professional services as Exhibit 1) as Work Order No. 7 for the Continuing Contract Agreement for Professional Services between IRC SWDD and Geosyntec, dated 18 June 2013. 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 XR14094\PR14027 20140523_REV engineers 1 scientists 1 innovators Mr. Himanshu H. Mehta, P.E. 23 May 2014 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. The on -Site IP&T system was installed to provide hydraulic containment of the high concentration area of the dissolved groundwater plume in December 2002. A Remedial Action Plan (RAP) was developed in July 2003, concurrent with the groundwater monitoring activities and IP&T system operation. The RAP outlined a proposed remedy for the VOC-impacted area of the Site, including (but not limited to), expansion of the existing IP&T system and construction of an infiltration gallery for effluent re-injection, which was completed in 2004. The infiltration gallery was retrofitted in 2008, in accordance with design specifications described in the May 2007 RAP Modification document, and is currently being used as part of the biobarrier transect 1 at the Site. The FDEP approved discontinuing the use of the IP&T system in a letter dated 2 August 2006, provided the system shutdown coincided with the approval and implementation of a Remedial Action Plan Modification (RAPM). A RAPM was submitted in May 2007 and approved by FDEP in August 2007 Geosyntec discontinued IP&T system operation and implemented the RAPM activities in April through June 2008. Since that time, the air stripper has been kept on-site for treatment of purge water. However, the blower on the air stripper is no longer functional and liquid waste generated during groundwater sampling events is currently being containerized in 55 -gallon drums for offsite disposal so the system can be dismantled. 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 — Data Evaluation and Semi -Annual Reporting; and • Task 6 — IP&T System Dismantling The remainder of this section presents a general description of the activities to be performed in each task. XR14096\PR14027 20140523_REV engineers 1 scientists 1 innovators Mr. Himanshu H. Mehta, P.E. 23 May 2014 Page 3 Task 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, and project administration. The budget includes two hours per month for the project manager over a 12 -month project duration and one hour per sampling/field event has been included 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 is anticipated that one of these meetings may include preparation of a presentation of the redevelopment assessment activities and results conducted to date under authorization from the Treasure Coast Regional Planning Committee (TCRPC). 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. 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 the evaluation of five sites, including South Gifford Road Closed Landfill (4701 41St Street), Old Administration Building (1840 25th Street), Former Cattle Dip Site (9255 93rd Street), North County Reverse Osmosis Plant (7751 58th Avenue), and Shadowbrook Estates (7775 85th Street). Task 4 — Semi -Annual Sampling Activities: Under this task, Geosyntec will perform all field activities related to the plume groundwater monitoring. The field 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, 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 wells. Sampling activities will be completed with a combination of Passive Diffusion Bag (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 2014 sampling event will be deployed during the summer 2014 event after sampling activities are completed). XR 14096\PR 14027 20140523_REV engineers 1 scientists 1 innovators Mr Himanshu H. Mehta, P.E. 23 May 2014 Page 4 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 2014 (tentatively in June) and will include sampling of 59 monitoring wells (43 wells using PDBs and 16 wells with traditional sampling techniques). The annual field event is budgeted to include four days for groundwater sampling activities and one day for PDB deployment for the next sampling event (total of five field days). The proposed semi-annual field event will be conducted in winter 2014 (tentatively in December) and will include sampling of 30 monitoring wells (29 wells using PDBs and 1 well 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 of the groundwater plume The groundwater samples will be analyzed in accordance with the sampling plan summarized in the December 2013 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 three 55 -gallon polyethylene drums, analysis of three TCLP sample for IDW characterization, and two transport trips. Overall, budget has been included for ten field days with a two -person team (i.e., 20 man days) and associated field expenses. Task 5 - Data Evaluation and Semi -Annual Reporting: Under this task Geosyntec will perform data evaluation activities and prepare two semi-annual reports for submittal to FDEP. 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 results of groundwater sampling associated with the CVOC plume monitoring will be presented in a report 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 draft 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. XR14096\PR14027 20140523 REV engineers 1 scientists 1 innovators Mr. Himanshu H. Mehta, P.E. 23 May 2014 Page 5 Task 6 — IP&T System Dismantling: Under this task, Geosyntec will provide contractor oversight to dismantle and dispose of the IP&T system and system appurtenances. The air stripper will be cleaned and decontaminated. It is anticipated that the concrete will be recycled. Parts of the system that are in reusable condition will be retained for reuse by IRC, if needed (this may include submersible pumps in the recovery wells and/or the air stripper). Recovery wells will be properly abandoned by a Florida -licensed driller. Geosyntec will remove and dispose of above -ground piping/conduit, characterize the waste generated as part of these activities, and oversee waste removal. Overall, the fieldwork is anticipated to require seven man days. Labor hours and related field expenses have been included for this fieldwork, as well as time for contractor procurement and field support. 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 2014. The on -Site P&T system dismantling can be conducted upon authorization from IRC SWDD and based on subcontractor availability.
