Mr. Himanshu H. Mehta, P.E. 5 January 2023 Page 5 Multi Sector General Permit The SWDD authorization to discharge the overflow of stormwater from the sedimentation pond into the C-6 canal is governed by a five-year Multi Sector General Permit (MSGP) issued by FDEP. The permit requires that the outfall be sampled quarterly during the first and fourth year of the permit for a list of parameters and the results reported to the FDEP by the first quarter of the fifth year of the permit. Storage Tank Groundwater Monitoring Wells Installation, 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 SWDD to use an existing 500,000 -gallon tank as a leachate storage tank for the proposed leachate evaporator system for the Class I Landfill. Conditions of this approval require SWDD to install four new groundwater monitoring wells (MW -49 to MW -52) around the periphery of the leachate storage tank, 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. SWDD is required to provide FDEP with monitoring well installation report, background groundwater quality report from the initial four sampling events, first semi-annual groundwater monitoring report with results of the first two quarterly sampling events, and first annual summary report. The installation report is due 90 days from the effective date of the Order with the background quality report due 30 days from installation of the monitoring wells. 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. It is understood that the leachate storage tank is anticipated to go into operation the first quarter of 2023; however exact dates are unknown. However, Geosyntec has included the scope of work and budget estimate to complete the reporting requirements of the Order. 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) compliance with Title V permit requirements; (iv) compliance with MSGP permit requirements; (v) other technical and miscellaneous permit compliance support services that may be required by SWDD in 2023; and (vi) storage tank monitoring wells installation, sampling and reporting as required by the Order.
