Mr. Himanshu H. Mehta, P.E. 19 November 2019 Page 9 ammonia in regard to the Site. Following the creation of the alternative GCTL, Geosyntec would re-evaluate ammonia results for the Site. • Use of FDEP Rounding Memo — FDEP approves rounding analytical results to the same number of significant figures used to express the applicable GCTL. This guidance is currently not being applied to screening of analytical results at the Site. If applied, concentrations of benzene in monitoring well MW -21 S would be considered below the GCTL in 50% fewer monitoring events since 2017. • Background Stud L— In regard to metals exceedances at the Site, we recommend conducting a background study, as these analytes are typically natural occurring in the vicinity of a landfill. This study would include research of nearby analytical data and research of other C&D debris disposal facility data as well as the adjacent Class I landfill data. Our recollection is that there has been some exceedances of iron and arsenic in groundwater wells north of the Class I Landfill, and this was attributed to the borrow pond north of the Class I landfill. Results of this study could also remove the need for surface water sample collection at the Site. The objective of the above evaluation is to see if the site data supports a reduced monitoring network and frequency in the vicinity of the C&D debris disposal facility and therefore propose to FDEP for returning it to return to semi-annual monitoring program that is required by the solid waste permit. SCHEDULE Geosyntec will initiate work immediately upon receipt of Notice to Proceed (NTP) from SWDD. The compliance reports required by each permit will be completed and submitted to FDEP before the deadlines discussed above. Other technical and miscellaneous permit compliance support services will be provided on an as -needed basis. BUDGET ESTIMATE Geosyntec proposes to perform the above -referenced work on a lump sum basis for $157,629. A budget estimate for the scope of work outlined in Phases 1 through 5 of this proposal is summarized in the following table, and a detailed budget estimate is provided as Attachment 1. The budget estimate presented in this proposal is based on Geosyntec's understanding of the project requirements, our experience gained from executing similar tasks for SWDD during 2007 and 2008, and experience with compliance monitoring, and reporting at similar facilities. Phase 1 — Project Management/Meetings $26,198.20 Phase 2 — Semi -Annual Sampling and Reporting $61,860.79 NCP2019_2283/JL19022 2020 Compliance Monitoring Proposal
