Mr. Himanshu H. Mehta, P.E. 20 December 2023 Page 4 from two staff gauges (C5 -SWI and C5-SW3) for Total Ammonia Nitrogen [TAN] calculation 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 -535. Therefore, sampling of the four Class I landfill groundwater evaluation monitoring wells and four surface water field parameter screening locations will be included in the 2024 quarterly monitoring and reporting program. 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 July 22, 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. Although the first quarter of sampling (after the tank has been filled) was conducted in October 2023, a second quarter of groundwater sampling is planned to be conducted in January 2024 and subsequent quarterly monitoring thereafter. Upon conducting the second quarter of sampling, the SWDD is required to provide FDEP with first semi-annual groundwater monitoring report with results of the first two quarterly sampling events, and the first annual summary report. The first semi-annual and annual summary reports are due 240 days and 400 days, respectively, from initial filling of the tank with leachate from the Class I Landfill for the leachate evaporator. This proposal presents the scope of work and budget estimate for the: (i) semi-annual water - quality compliance monitoring and reporting for the Class I landfill and C&D debris disposal facility; (ii) quarterly assessment monitoring of the eight groundwater wells and three surface water sample sites for the C&D debris disposal facility; (iii) quarterly evaluation monitoring of the ..wells and .. surface water sample sites for the Class I landfill; (iv) storage tank monitoring well sampling and reporting as required by the Order; (v) compliance with Title V permit NCP2323548/JL23073_2024 Compliance Monitoring Proposal engineers I scientists I innovators
