Mr. Himanshu H. Mehta, P.E. Geosyntec 8 May 2015 consultants Page 3 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. 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 up to five sites, including, at a minimum, South Gifford Road Closed Landfill (4701 41' Street), Old Administration Building (1840 25th Street), and North County Reverse Osmosis Plant(7751 58t"Avenue). Task 4—Semi-Annual Sampling Activities: Under this task, Geosyntec will perform 2015 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, procurement of Passive Diffusion Bag (PDB) samplers 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 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 2015 sampling event will be deployed during the summer 2015 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 2015 (tentatively in June) and will include sampling of 57 monitoring wells (46 wells using PDBs and 11 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 2015 (tentatively XR15143\XR15021 engineers I scientists 1 innovators 243
