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 .

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
