This fee proposal is based on correspondence with the Florida Department of Environmental Protection (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 respond to FDEP correspondence and prepare an annual pollution liabilities evaluation report for all County-owned environmental liabilities. Geosyntec has prepared this proposal (professional services as Exhibit 1 ) as Work Order No . 6 for the Continuing Contract . Agreement for Professional Services between IRC SWDD and Geosyntec, dated 15 November 2011 . 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 : (1) 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. XR13056\PR13006 041713 .docx engineers I scientists I innovators Mr. Himanshu H. Mehta, P .E. 19 April 2013 Page 2 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/Response to FDEP Comments ; • Phase 3 — Required Notification Activities ; • Phase 4 — Annual Pollution Remediation Liabilities Evaluation; • Phase 5 — Semi-Annual Sampling Activities ; and • Phase 6 — 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 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 12M month project duration and two hours per sampling/field event has been included for the principal-in-charge . Phase 2 — Meetines/Response to FDEP Comments 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 evaluation of redevelopment options prepared by Geosyntec under a previous authorization. The site has recently been transferred to a new FDEP District (from Central to Southeast). FDEP provided comments on the last semi-annual groundwater monitoring report in a letter. dated 29 March 2013 , which requested a written response to their comments and questions by 2 June 2013 . Most of the comments are related to clarification for the new FDEP project manager. Under this task, Geosyntec will prepare and submit the response to FDEP comments on the December 2012 Semi-Annual Groundwater Monitoring Report. XR130561PR13006 041713 .docx engineers ( scientists I innovators Mr. Himanshu H. Mehta, P .E. 19 April 2013 Page 3 Phase 3 — Required Notification Activities FDEP requested in their 29 March 2013 letter that the County establish a temporary point of compliance (TPOC) beyond the property boundary of the landfill, as required by Rule 62- 780 .220 . Under this task, Geosyntec will complete the activities required to establish the temporary extension of the TPOC , including : (i) preparing a notification package (i .e . , to provide written notice in accordance with Rule 62-780.220(3)) to the County Health Department and all real property owners into which the point of compliance is allowed to extend); (ii) assisting IRC SWDD with preparation of the notice to be published (by IRC SWDD), as required, in a standard-size newspaper of general circulation ; and (iii) providing copies of notices, to FDEP to document completion of the process . Phase 4 — Annual Pollution Remediation Liabilities Evaluation As requested by IRC SWDD, under this task, Geosyntec will prepare the annual environmental is evaluation. This document is prepared annually in response to Governmental Accounting Standards Board Statement No. 49 (GASB No . 49), Accounting and Financial Reportingfor 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 six 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) . Phase 5 — Field Activities Under this task, Geosyntec will perform all field activities related to the plume groundwater monitoring, as discussed herein. 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 . With FDEP ' s approval for use of Geosyntec-recommended Passive Diffusion Bag (PDB) Samplers, the sampling activities will be completed in less time than previous events that have been performed with traditional low-flow sampling techniques. A minimum of two weeks prior to the summer semi-annual sampling event, Geosyntec personnel will deploy the . PDBs in wells proposed for sampling using this technique (i .e . , wells that are at least 1 -in diameter and are being sampled only for volatile organic constituents [VOCs]) . PDBs are anticipated to be purchased from ALS Group, one of the few suppliers of this type of passive XR13056\PR13006_041713.docx engineers I scientists I innovators Mr. Himanshu H. Mehta, P.E. 19 April 2013 Page 4 sampling device and the only analytical laboratory that supplies them. This effort is anticipated to be completed by one field person within one day . PDBs for subsequent events will be deployed after each of the semi-annual sampling events are completed to save an additional mobilization (e .g. the PDBs to be sampled during the winter 2013 sampling event will be deployed during the summer 2013 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 2013 (tentatively in June) and will include sampling of 62 monitoring wells (41 wells using PDBs and 21 wells with traditional sampling techniques) . The annual field event is budgeted to include one day for PDB deployment (as a separate mobilization at least 14 days prior to sample collection), three 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 2013 (tentatively in December) and will include sampling of 29 monitoring wells ( 12 wells using PDBs and 17 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 of the groundwater plume . The groundwater samples will be analyzed in accordance with the sampling plan summarized in Table 9 of the December 2012 Semi-Annual Groundwater Monitoring Report. In addition, three samples will be analyzed for Total Recoverable Petroleum Hydrocarbons (TRPH), Total Dissolved Solids (TDS), sodium, chloride , and bromide, in follow-up to the injection activities completed in 2012 , as requested by FDEP. 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) . It is anticipated that purge water (investigation-derived waste [IDW]) will be treated in the existing air stripper sump (using a temporarily connected air compressor) and discharged to the sanitary sewer following treatment. No costs are included herein for IDW disposal or analytical costs . XR13056\PR13006 041713 .docx engineers I scientists I innovators Mr. Himanshu H. Mehta, P .E. 19 April 2013 Page 5 Phase 6 — Data Evaluation and Semi-Annual Reporting Under this task, Geosyntec will perform data evaluation activities and prepare semi-annual reports for submittal to FDEP . Data evaluation activities will include database management, data evaluation and screening, geographical information systems (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. SCHEDULE Geosyntec will conduct the groundwater monitoring and reporting activities on 'a semi-annual basis as described herein. The response to comments on the last report is due to FDEP by 2 June 2013 . The semi-annual groundwater monitoring events will be tentatively conducted in June and December 2013 .
