Mr. Himanshu H. Mehta, P.E. 27 April 2021 Page 3 Geosynte& consultants Task 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 five hours per sampling/reporting event and one hour per month for the project manager (22 hours total), one hour for the senior principal - in -charge, and one hour per month (12 hours total) for the administrative assistant. Task 2 — Meetings/Regulatory Interaction: Under this task, Geosyntec will prepare for and attend up to two meetings, with IRC SWDD, FDEP, and/or:1RC Board of County Commission, as necessary. It has been assumed that one of these meetings will be in person and one meeting will be by video or conference call. Also, under this task, four hours has been included for the senior principal -in -charge 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 two sites, including South Gifford Road Closed Landfill (4701 41St Street) and Former Premier Citrus Property (375 82nd Street). In addition, two hours have been included for a Florida registered professional engineer to conduct an independent review of the liability evaluation. Task 4 — Semi -Annual Sampling Activities: Under this task, Geosyntec will perform 2021 field activities related to the performance monitoring and plume groundwater monitoring. The semi-annual 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 well network. Sampling activities in 2021 will be completed with a combination of PDB samplers and traditional low -flow sampling techniques and will transition to PDB samplers only in 2022. PDBs are anticipated to be purchased from EON Products, one of the few suppliers of this type of passive sampling device. 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 summer 2021 field event (tentatively scheduled for June) will include sampling of nine monitoring wells (seven wells using PDBs and two wells with traditional sampling techniques). The summer 2021 field event is budgeted to include one-half day for groundwater sampling activities and one day for PDB deployment for the next sampling event (total of one and one-half [ 1.5] field days each with two persons).
