Mr. Himanshu H. Mehta, P.E. <br />30 April 2018 <br />Page 3 <br />Geosynteccl <br />consultants <br />Task 2 — Meetings/Regulatory Interaction: Under this task, Geosyntec will prepare for and <br />attend up to two meetings, with IRC SWDD, FDEP, and/or IRC Board of County Commission, as <br />necessary. It has been assumed that one of these meetings will be in person and one meeting will <br />be by conference call. Also, under this task, six hours has been included for the principal -in -charge <br />to provide ongoing support to IRC SWDD related to interaction and negotiation with FDEP. <br />Task 3 — Annual Pollution Remediation Liabilities Evaluation: As requested by IRC SWDD, <br />under this task, Geosyntec will prepare the annual environmental liability evaluation. This <br />document is prepared annually in response to Governmental Accounting Standards Board <br />Statement No. 49 (GASB No. 49), Accounting and Financial Reporting for Pollution Remediation <br />Obligations, which requires the inclusion and calculation of pollution remediation obligations. The <br />objective of GASB No. 49 is to enhance the usefulness and comparability of pollution remediation <br />obligation information reported by state and local governments. It has been assumed that the report <br />will include evaluation of two sites, including South Gifford Road Closed Landfill (4701 41" <br />Street) and Old Administration Building (1840 25th Street). In addition, two hours have been <br />included for a Florida registered professional engineer to conduct an independent review of the <br />liability evaluation. <br />Task 4 — Semi -Annual Sampling Activities: Under this task, Geosyntec will perform 2018 field <br />activities related to the performance monitoring and plume groundwater monitoring. The semi- <br />annual activities will include field preparation, groundwater sampling, and water level <br />measurements. Field preparation activities will include scheduling and staffing, subcontracting, <br />coordination with the analytical laboratory, field equipment preparation, procurement of Passive <br />Diffusion Bag (PDB) samplers, and notifying FDEP and Vero Beach Municipal Airport of the <br />field schedule. Performance monitoring well MW -37B associated with the RAPM3 <br />implementation is included in the semi-annual sampling plan for analysis of bioremediation <br />performance parameters, including dissolved gasses, total organic carbon, and dechlorinating <br />microbial concentration. <br />Geosyntec will perform the groundwater sampling activities associated with the CVOC plume <br />monitoring well network. Sampling activities will be completed with a combination of PDB <br />samplers and traditional low -flow sampling techniques. PDBs are anticipated to be purchased from <br />EON Products, one of the few suppliers of this type of passive sampling device. Two PDB <br />harnesses will be purchased from EON Products for monitoring wells GR-MW02C and GR- <br />MW22CCR. Groundwater sampling activities will be executed using a two -person sampling crew <br />and will be performed in general accordance with the FDEP Standard Operating Procedures <br />(SOPS). The proposed summer 2018 field event (tentatively scheduled for June) will include <br />sampling of nine monitoring wells (three wells using PDBs and six wells with traditional sampling <br />techniques). The summer 2018 field event is budgeted to include one day for groundwater <br />sampling activities and one day for PDB deployment for the next sampling event (total of two field <br />days each with two persons). The proposed winter 2018 field event (tentatively scheduled for <br />FR0766\XR18011 <br />engineers I scientists I innovators <br />
