Mr. Himanshu H. Mehta, P.E. 12 April 2019 Page 2 Geosyntec° consultants In consideration of the ongoing natural attenuation processes occurring at the site, the enhancement of these biological processes via the injection of an electron donor was proposed and agreed to in concept by the FDEP in correspondence dated 2 August 2006. In response to FDEP's request and supported by groundwater monitoring results, Geosyntec conducted an injection event in 2017 [Remedial Action Plan Modification Addendum No. 3 (RAPM 3)] to remediate recalcitrant CVOC groundwater impacts in the former source area. Semi-annual performance monitoring associated with bioremediation implementation is ongoing at monitoring wells GR-MW3OB and GR- MW37B and conducted concurrently with groundwater monitoring of the plume monitoring well network. PROPOSED SCOPE OF WORK The proposed scope of work consists of semi-annual groundwater monitoring and reporting and related activities to be performed on behalf of IRC SWDD at the Former South Gifford Road Landfill. For the purpose of budgeting, the scope of work has been divided into the following tasks: • Task 1 — Project Management; • Task 2 — Meetings/Regulatory Interaction; • Task 3 — Annual Pollution Remediation Liabilities Evaluation; • Task 4 — Semi -Annual Sampling Activities; • Task 5 — Data Evaluation and Semi -Annual Reporting; The remainder of this section presents a general description of the activities to be performed in each task. Task 1 — Project 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 six hours per sampling/reporting event and one hour per month for the project manager (24 hours total), two hours for the 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 IRC Board of County Commission, as necessary. It has been assumed that one of these meetings will be in person and one meeting will FR0766\XR19012 engineers 1 scientists 1 innovators
