Mr. Himanshu H. Mehta, P.E. <br />14 December 2021 <br />Page 4 <br />initiated on 17 September 2020 through a second RTC letter provided to FDEP. Geosyntec <br />installed the three (3) groundwater evaluation monitoring wells in November 2020 (evaluation <br />monitoring well not installed downgradient of MW -14S since MW -14S was already located at <br />the edge of the Class I landfill zone of discharge), sampled the four (4) quarterly wells and <br />collected field parameters from two staff gauges (C5 -SWI and C5-SW3) for Total Ammonia <br />Nitrogen [TAN] calculation in November 2020. During the 2021 quarterly sampling, Geosyntec <br />working on behalf of SWDD reduced the quarterly parameters analyzed and negotiated the use <br />of a site-specific ammonia GCTL based on TAN calculations thus adding a surface water <br />screening location north of MW -535. <br />Therefore, sampling of the four Class I landfill groundwater evaluation monitoring wells and <br />four surface water field parameter screening locations will be included in the 2022 quarterly <br />monitoring and reporting program. <br />Title V Air Operation Permit Compliance <br />The SWDD was issued a Title V Air Operation renewal permit (Permit No. 0610015 -007 -AV) <br />effective June 1, 2017. The permit requires that the SWDD prepare and submit to FDEP and the <br />U.S. Environmental Protection Agency (USEPA), Region 4 the following: <br />• Annual statement of compliance (within 60 days after the end of the calendar year); <br />• Electronic Annual Operating Report (AOR) and Title V Emissions Fee (on or before <br />April 1 of each year, for the previous calendar year); <br />• Semi -Annual Monitoring Report (scheduled for March 1 and August 29); and <br />• Results of an annual landfill gas (LFG) sulfur content test (Annual Emissions Report for <br />Sulfur Dioxide letter report and included in the Electronic Annual Operating Report). <br />The annual emissions fee is automatically calculated based on emissions reported for marked <br />pollutants on the FDEP's electronic Annual Operating Report (EAOR). Upon submission of the <br />EAOR, the Annual Title V Emissions Fee invoice is generated, and this must be paid by April 1, <br />2022 for the 2021 reporting period. <br />Landfill Gas Migration Monitoring <br />The Class I Landfill solid waste permit also requires quarterly monitoring of LFG migration <br />around the perimeter of the site and within enclosed structures. <br />NCP2021-3441/JL21090 2022 Compliance Monitoring Proposal.Final.doc <br />
