Mr. Himanshu Mehta, P. E. 21 November 2025 Page 6 Geosyntec will provide one electronic copy of the draft permit application package to IRC SWDD for review. Following receipt of comments from IRC SWDD on the draft documents, Geosyntec will produce an electronic copy of the final permit application for submittal to FDEP and IRC SWDD. Geosyntec has assumed IRC SWDD will pay any fees associated with a permit modification in accordance with paragraph 62-701.315(3)(a), F.A.C. for Class I landfills. No effort is assumed for responses to Request for Additional Information (RAIs) at this time. The level of effort required for RAI responses will be evaluated upon receipt of RAIs and a separate budget addendum will be developed based on the anticipated responses. Phase 5: Assessment of Existing GCCS A thorough understanding of the functionality of the existing GCCS is crucial to SWDD's satisfaction of gas quantity and quality targets for the overall GCCS and RNG facility operational objectives. Geosyntec recommends that a GCCS assessment be performed to benchmark the current operational status of the GCCS. The .information gleaned from this assessment will be critical to identifying underperforming areas of the GCCS and optimizing performance of the existing system. As such, Geosyntec's scope of services for this task will include a combination of in -field data collection and office -based data interpretation and modeling. Members of Geosyntec's team will visit the site and perform a review of the existing GCCS. This will include the following in -field services: • Kickoff meeting to discuss the objectives and logistics associated with the field work. It is assumed that Nopetro and SWDD staff will attend the meeting to provide information regarding operation of the GCCS wellfield and flare; • visual inspection of each vertical well for damage, subsidence, leakage, compromised operation, and other observable conditions; • water level measurements in each accessible vertical gas collection well, including a sounding of the total well depth; • vertical well proofing to assess verticality and accessibility of the well casing; • identification of the solid casing/screen transition in each accessible well; and • a site -wide Sniffer DRONE flyover to capture methane emissions data at the surface of the landfill. Sniffer Robotics, Inc. will perform the flyover and provide the following deliverables: o Leak source location report that provides locations where methane emissions would exceed minimum thresholds for remediation if inspected in accordance with USEPA Method 21 methods.
