Mehta, P .E . Managing Director Solid Waste Disposal District Indian River County 1325 74th Avenue SW Vero Beach, Florida 32968 Subject: Proposal to Implement FDEP-Required Activities Former South Gifford Road Landfill Vero Beach, Indian River County, Florida Dear Mr. Mehta : Geosyntec Consultants (Geosyntec) is pleased to submit this letter proposal to the Indian River County (IRC) Solid Waste Disposal District ( SWDD) to provide professional services to implement FDEP-required activities associated with continued groundwater monitoring for the chlorinated volatile organic compound (CVOC) plume at the Former South Gifford Road Landfill located in Vero Beach, Indian River County, Florida. This fee proposal includes budget for various field activities required by FDEP and/or as requested by IRC , as well as ongoing project support activities related to notification activities and coordination and interaction with FDEP, Florida Department of Health (FDOH), and Treasure Coast Regional Planning Council (TCRPC) . Geosyntec has prepared this proposal (professional services as Exhibit 1 ) as Amendment No . 1 to existing Work Order No . 7 for the Continuing Contract Agreement for Professional Services between IRC SWDD and Geosyntec, dated 15 November 2011 . The remainder of this letter provides an overview of the project background, a description of the proposed scope of work, a budget estimate, and a discussion of the schedule for accomplishment of the work described herein . PROJECT BACKGROUND CVOCs were discovered in groundwater in samples collected at the site in 1999 , and Geosyntec implemented ongoing assessment, semi-annual plume monitoring, and remediation activities , as required by the FDEP. Remediation activities have been ongoing at the Site since 2003 , and have included. aggressive source area excavation (including an area with dense non-aqueous phase liquid [DNAPL] ), interim pump and treat (IP&T) for hydraulic control of Site groundwater, source area bioremediation, and associated natural attenuation monitoring for the downgradient dissolved plume . In support of the ongoing semi-annual groundwater monitoring program at the Site, FDEP has required maintenance of the monitoring network, including rehabilitation, reinstallation, and professional land surveying of several monitoring wells . As approved by FDEP, operation of the IP&T system was discontinued in June 2008 ; however, XR13056\PR13082- 122013 .docx engineers I scientists I innovators 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. Field preparation XR 13056\PR 13082- 122013 .docx engineers I scientists I innovators Mr. Himanshu H . Mehta, P .E . 20 December 2013 Page 3 activities will include scheduling and staffing, subcontracting, coordination with the analytical laboratory, and field equipment preparation . Replacement monitoring wells will be installed using a sonic drill rig and constructed similar to existing Site monitoring wells . Monitoring wells will be constructed of 24nch Schedule 40 (SCH 40) polyvinyl chloride (PVC) with 10 ft of 2 -inch SCH 40 PVC standard factory-slotted (0 . 0104nch) screen . The wells will be completed flush with ground surface in a traffic-rated manhole vault placed in a 2 ft by 2 ft concrete pad . The wells will be developed until visually free of particulates, as observed by the on-Site Geosyntec representative . It has been assumed that the well installation, development, and surveying activities can be completed in two field days with one person . Any soil or liquid investigation-derived waste (IDW), consisting of soil cuttings from well installation, decontamination fluids and well development water, will be placed in 55 -gallon drums, labeled , and staged at the Gifford Road Landfill . One representative sample for TCLP from each waste stream (solid and liquid) will be collected for waste characterization . Geosyntec will arrange for transportation of the drums for disposal at the IRC Main Landfill in Vero Beach, Florida. Solid and liquid waste will be analyzed for TCLP short list of CVOCs and benzene, toluene, ethylbenzene, and xylenes (BTEX) . In addition, liquid waste will be analyzed for pH and flashpoint. Waste characterization samples will be collected concurrently with the field activities described above . Budget has been included herein for transportation to the landfill ; however, it has been assumed that IRC SWDD will be responsible for disposal costs associated with the non-hazardous drum disposal . FDEP approved discontinuing the use of the IP&T system in conjunction with implementation of Remedial Action Plan Modification (RAPM) activities in 2008 . Since that time, the air stripper has been kept on- site for treatment of purge water. It is our understanding that because of potential future site redevelopment activities currently under discussion, the system will be dismantled and decommissioned. Geosyntec will characterize the GAC for disposal, as well as provide oversight and coordination of a remediation contractor to transport the spent GAC to the IRC Main Landfill for disposal . Under this task, one sample will be collected from the GAC vessel and analyzed for TCLP CVOCs and BTEX . One field day for one person has been included for oversight of GAC transport and disposal activities . It has been assumed that the remediation contractor will vacuum the GAC from the vessels and transport the spent GAC to the IRC Main Landfill, where it will be disposed of as non-hazardous waste . Budget has been included for transportation to the landfill ; however, it has been assumed that IRC SWDD will be responsible for disposal costs associated with the non-hazardous GAC disposal . Geosyntec will perform PDB deployment activities associated with the CVOC plume monitoring wells a minimum of two weeks prior to the summer semi-annual sampling event . PDBs are anticipated to be purchased from EON Products, Inc . and it has been assumed that they will be deployed in one field day by one person in conjunction with other Site work. XR 13056\PR 13082- 122013 .docx engineers I scientists I innovators Mr. Himanshu H . Mehta, P . E. 20 December 2013 Page 4 Overall, the field activities are anticipated to require oversight by Geosyntec personnel for a total of four days on Site . For the PDB deployment ( 1 day), per diem has not been included for Geosyntec field personnel because it has been assumed that it will be conducted while on- Site completing separately authorized activities . The drilling subcontractor will be on- Site for two days . SCHEDULE The field activities described herein can be initiated within two to three weeks of receipt of notice to proceed from the County, assuming subcontractor availability . A description of the field activities will be included in future semi -annual groundwater monitoring report(s) . BUDGET ESTIMATE A budget estimate for the scope of work outlined in Phases 1 and 2 of this proposal is summarized in the following table, and a detailed budget estimate is provided as Attachment A . The budget estimate presented in this proposal is based on Geosyntec ' s understanding of the project requirements, our experience gained from executing similar tasks for SWDD since 2002 at the Site, and experience with groundwater monitoring and reporting activities at similar facilities . Phase 1 — Project Management and Ongoing Technical Support $2,468 Phase 2 — Field Activities * $20, 506 TOTAL $229974 Field activities cost will be reduced by up to $3,500 if monitoring well GR-MW22CC can be redeveloped and does not require replacement.
