Mr. Himanshu Mehta, P.E. Managing Director 7 November 2019 Page 4 Geosyntec will contact the Florida Department of Environmental Protection (FDEP) Solid Waste Section and Division of Air Resource Management (DARM) for the regulatory and permitting requirements for the pilot study as well as the eventual full-scale commercial system for the IRC Class I Landfill. Geosyntec will also review relevant documents including work plans, shop drawings and process diagrams, start-up and shut -down procedures, etc. provided by IRED and Heartland prior to the start of the pilot study. Based on a review of these documents, Geosyntec will coordinate with SWDD and/or IRED/Heartland for the sampling of leachate and final residuals from the evaporation for testing by an approved testing laboratory. The list of analytical parameters, including VOCs and HAPs, will be prepared by Geosyntec for review and agreed to by SWDD, IRED and Heartland prior to the start of the pilot study. In addition, any air sampling and stack emissions testing that may be required by DARM of FDEP will be included. For budgeting purposes, we have assumed that the sampling and laboratory analytical testing will be contracted directly by either SWDD or IRED/Heartland. Geosyntec will conduct a site visit during the pilot study. For budgeting purposes, we have assumed that the site visit would be conducted by one Geosyntec personnel during the actual evaporation process (i.e., pilot test). Based on our understanding of the pilot study proposed by IRED/Heartland, the process will involve installation and operation of a pilot system to evaporate approximately 1,000 gpd of leachate for a total duration of five (5) days. Therefore, Geosyntec will make the site visit during Day 2 or 3 of the pilot study in order to observe the actual evaporation process. Phase 3 — Evaluation of Pilot Study Results The results of the plot study will be evaluated to: (i) assess the LFG or heat energy requirements to evaporate the Landfill leachate; (ii) effectiveness of the evaporation system to confirm the percent volume reduction; (iii) the need to further process the residuals to pass the Paint Filter Liquids Test and TCLP requirements for disposal at the IRCL facility or another off-site facility and its cost implications; and (iv) re-evaluate final system costs. The evaluation will also address the permitting requirements (including leachate, residuals, air emissions sampling and testing) by both FDEP Solid Waste Section and DARM with the understanding that the commercial unit might be installed on the IRED property and not the IRC Landfill property. As such, preliminary costs for the design, permitting, and construction of a piping system to convey leachate from IRC Landfill to the IRED property will be prepared. Phase 4 — Preparation of Technical Memorandum A technical memorandum will be prepared as the deliverable for the above scope of work. The memorandum will include discussions of the site visit, analytical results of leachate and residuals samples collected during the pilot study, permitting requirements, air quality and secondary containment requirements, preliminary leachate conveyance piping system costs, processing costs
