spilling of leachate into areas that may impact surface or groundwaters. Rather, <br /> SWDD determined that the Alternate Procedure with additional monitoring and <br /> spill prevention provisions would better serve the intent. <br /> 2. The Consultant evaluated the required footprint of secondary containment to meet <br /> the rule (110% of the storage capacity of the tank, or 550,000 gallons). The <br /> proximity of the existing GST to the lift station,pump manifold and electrical <br /> panels, coupled with the configuration of the proposed evaporation system and <br /> existing utilities made it prohibitive to construct the required containment. <br /> Furthermore,the Consultant reviewed original geotechnical reports and GST <br /> design documents to determine if the required vertical containment(liner or <br /> compaction below the tank)was suitable for meeting the intent of the Rule. <br /> Ultimately,the available information was not sufficient to make this <br /> determination. <br /> 3. An Alternate Procedure allows the applicant to request approval of an alternate <br /> method of meeting the intent of a given Rule. In this case, the Consultant prepared <br /> a request that identified additional monitoring,testing and tank modifications that <br /> could serve to prevent or quickly mitigate a spill or leak in lieu of constructing a <br /> physical containment structure. The Consultant will participate in several phone <br /> calls with FDEP staff,prepare supporting documents, coordinate with project <br /> teams(regarding minimum storage requirements) and SCADA consultants <br /> (regarding instrumentation and controls available to monitor for leaks)to prepare <br /> the package to be submitted to FDEP. Several follow-up meetings and a <br /> resubmittal of additional information will also be conducted. <br /> The original Scope of Services did not anticipate a requirement for modification of the <br /> FDEP Solid Waste Operations permit; however,the requirement for the Alternate <br /> Procedure triggered the requirement. The Consultant will prepare the request for an <br /> Alternate Procedure from FDEP including supporting documentation and will assist <br /> SWDD's permitting consultant to incorporate this change into the ongoing Operations <br /> Permit Modification(by others). <br /> Amendment No. 1 provides for these additional services associated with evaluating the <br /> secondary containment options and pursuing the Alternate Procedure request. <br /> Task 5: Construction Phase Services (Not-to-Exceed) <br /> No changes. <br /> Page 3 of 6 <br />
