Mr. Himanshu H. Mehta, P .E . 20 December 2013 Page 2 treatment system components, including piping, air stripper, and liquid-phase granular activated carbon (GAC) vessels remain at the Site . Until recently, the system was used for treatment of liquid investigation-derived waste generated at the Site during groundwater monitoring and related activities . The IP&T system is no longer required for the Site ; and therefore, IRC has requested that activities related to system decommission be completed . In addition, portions of the dissolved plume north of the former source area extend past the Site boundary necessitating the establishment of a temporary point of compliance (TPOC) . Support for these activities was included in Work Order No . 7 ; however, the activities have expanded in scope, requiring coordination with FDOH and additional technical support by Geosyntec . PROPOSED SCOPE OF WORK The proposed scope of work consists of ongoing project management and technical support related to notification activities and implementation of FDEP-required well rehabilitation and waste management activities associated with groundwater monitoring and former IP&T system at the Site . For the purpose of budgeting, the scope of work has been divided into the following phases : (i) Phase 1 — Project Management and Ongoing Technical Support; and (ii) Phase 2 — Field Activities . The remainder of this section presents a general description of the activities to be performed in each phase . Phase 1 — Proiect Management and Ongoing Technical Support Under this task, Geosyntec will provide project and technical support for ongoing project needs that are out-of--scope of the current authorized work order. These activities include additional effort related to the required notification activities for establishment of a TPOC (to meet the requirements of Chapter 62-780 . 220 , FAC), preparation for and participation in meetings with IRC, FDOH, and/or TCRPC , as required, to support ongoing project needs, provision of regulatory support related to coordinating and scheduling field and office meetings with FDEP, and project administration and management of the additional field activities described herein . Phase 2 — Field Activities Under this task, Geosyntec will perform field activities related to : (i) maintenance of the plume monitoring network as approved by FDEP ; and (ii) profiling and disposing of the GAC in the former IP&T system and drummed investigation derived waste (IDW) staged at the Site . Specifically, this task includes the activities associated with contracting, scheduling, and providing oversight to drilling and surveying subcontractors, for the following activities related to maintenance of the plume monitoring network: (i) redevelopment of GR-MW22CC , and proper abandonment and reinstallation of the well if necessary based on redevelopment results ; (ii) proper abandonment, reinstallation, and development of GR-MW27D ; (iii) survey of up to three (3 ) new monitoring wells (GR-MW22CC , GR-MW2713, GR-MW36D) ; (iv) toxicity characteristic leaching procedure (TCLP) sample collection of the GAC from the former IP&T system and drummed IDW ; and (v) deployment of passive diffusion bag (PDB) samplers in site monitoring wells for retrieval during the summer semi-annual sampling event.
