Mr. Himanshu H. Mehta, P.E. 13 November 2025 Page 4 in November 2020. During the 2021 quarterly sampling, Geosyntec working on behalf of the SWDD reduced the quarterly parameters analyzed and negotiated the use of a site-specific ammonia GCTL based on TAN calculations thus adding a surface water screening location north of MW -53S. In 2024, Geosyntec further reduced the sampling scope for the remaining evaluation monitoring wells at the Class I landfill. Therefore, sampling of the seven Class I landfill groundwater evaluation monitoring wells and four surface water sample sites will be included in the quarterly monitoring and reporting program for 2026. Storage Tank Groundwater Monitoring Wells Sampling and Reporting Permit Modification No. 0128769 -033 -SO -MM' and Approval of Request for Alternate Procedure — SWAP 22-1 (i.e., Order), effective 22 July 2022, authorized the SWDD to use an existing 500,000 -gallon tank as a leachate storage tank for the leachate evaporator system for the Class I Landfill. Conditions of this approval required the SWDD to install four new groundwater monitoring wells (MW -49 to MW -52) around the periphery of the leachate storage tank, which were installed in February 2023. Upon well installations, the SWDD was also required to conduct an initial and three additional sampling events (on a weekly basis) and conduct two quarterly sampling events after the initial filling of the tank with leachate. Based on the timeline of when the tank was initially filled with leachate on 30 August 2023, the well installations, initial sampling event, and three weekly sampling events were documented to the FDEP in 2023. In 2025, Geosyntec completed four quarters of sampling from these wells and submitted the two Semiannual Reports. Based on review of the July 2022 Order, in 2026, the quarterly sampling is required to continue, and an Annual Report will be submitted to FDEP on behalf of SWDD. Title V Air Operation Permit Compliance The SWDD was issued a Title V Air Operation renewal permit (Permit No. 0610015 -010 -AV), proposed on 7 December 2022. The permit requires that the SWDD prepare and submit to the FDEP and the U.S. Environmental Protection Agency (USEPA), Region 4 the following: • Annual statement of compliance (within 60 days after the end of the calendar year); • Electronic Annual Operating Report (AOR) and Title V Emissions Fee (on or before April 1 of each year, for the previous calendar year); • Semi -Annual Monitoring Report (scheduled for March 1 and August 29); and ' These changes are also reflected in Permit Modification No. 0128769 -034 -SO -MM NCP2525467/2026 Compliance Monitoring Proposal_F engineers I scientists I innovators
