Mr. Himanshu Mehta, P. E. 12 January 2016 Page 2 The IRCL occupies 276 acres, with 22 acres used for construction and demolition (C&D) debris disposal. The C&D debris disposal facility is presently inactive. The Class I landfill includes the Segment 1 vertical expansion, Segment 2, an Infill Area located between Segment 1 and Segment 2, and Segment 3 Lateral Expansion with a total footprint of approximately 135 acres. The IRCL facility is currently operating under Florida Department of Environmental Protection (FDEP) solid waste construction and operation permits (with Permit Nos. SC31-0128769-019 and SO31-0128769-020, respectively), issued on 17 March 2011 with an expiration date of 2 December 2015. The approved construction permit (i.e., Permit No. SC31-0128769-019) authorized the construction of Phases I and II (Cells 1 and 2) of the Segment 3 Expansion, while the approved operation permit (i.e., Permit No. 5031-0128769-020) authorized the continued operation of the IRC Class I Landfill (Segment 1, Infill Area, Segment 2, and Segment 3, Phases I and 11 when constructed). The existing permits recognized the entirety of the Segment 3 Expansion footprint of approximately 76 acres (ac), but acknowledged that waste estimates projected only for the construction of Phases I and II (i.e., Cells 1 and 2) would be completed within the duration of the five-year permitting period. Only Phase I (Cell 1) of the Segment 3 Expansion was constructed, and is in operation, under Permit Nos. SC31-0128769-019 and SO31-0128769-020. On 6 January 2015, the SWDD Board authorized Geosyntec to prepare the permit application to renew both solid waste permits before the expiration date of 2 December 2015. This scope of work was in addition to other engineering services approved by the SWDD Board under CCNA- 2014-WO No. 1. Geosyntec subsequently completed and submitted a 20-year renewal permit application to FDEP on 27 September 2015, and has since then responded to requests for additional information (RAIs) by FDEP. On 11 December 2015, the FDEP provided a notice of its Intent to Issue Permits 0128769-022-SC and 0128769-023-SO to replace Permit Nos. SC31- 0128769-019 and SO31-0128769-020, respectively. Geosyntec assisted SWDD to review and provide comments on the Draft Permits that were enclosed with the FDEP's notice of intent. A notice of the intent to issue both permits was published by SWDD in the Press Journal on 17 December 2015 and the Final Permits were issued by FDEP on 5 January 2016. The Final Permits included the specific condition that SWDD installs groundwater monitoring well clusters (MW-45 and MW-46) immediately downgradient of the existing Cell 1 of the Segment 3 Expansion within 90 days of issuance of the permits by FDEP. This would allow FDEP to monitor the performance of Cell 1 until such time that Cell 2 is constructed and these wells abandoned. In the interim, FDEP agreed to suspend monitoring of well clusters MW-41 and MW-42 which have been installed east of Cell 2 until Cell 2 is constructed. It should be noted that SWDD anticipates to construct Cell 2 by 2017. SWDD has therefore requested Geosyntec to provide a proposal to install the monitoring well clusters required by FDEP.
