Task 2: Landfill Gas Skid Design <br /> Subtasks 2.5 and 2.6 have been modified to accommodate minor changes to the scope of <br /> the project. <br /> Subtask 2.1 Request for Information <br /> No changes. <br /> Subtask 2.2 30 Percent Design <br /> No changes. <br /> Subtask 2.3 60 Percent Design <br /> No changes. <br /> Subtask 2.4 90 Percent Design and Final Bid Package <br /> No changes. <br /> Subtask 2.5 Bidding and Project Management <br /> This task has been amended to provide for additional project management and <br /> coordination efforts. <br /> Subtask 2.6 Permitting <br /> The initial design assumed that no stormwater permitting(County or FDEP)would be <br /> required; however, due to the impacts from each of the ongoing projects (cumulatively), <br /> and potential modifications to the stormwater system and swale configuration in the <br /> vicinity of the evaporation system,the cumulative impacts appear to trigger the need for a <br /> modification to the County's Environmental Resource Permit (ERP). This task is being <br /> amended to provide coordination efforts for each project's drainage configuration, as well <br /> as coordination with the County's consultant responsible for the system-wide stormwater <br /> model(Geosyntec)to facilitate the permit modification. The permit modification and <br /> modeling updates will be performed by Geosyntec. The Consultant will compile the <br /> drawings (design by each projects' design team)and supporting documents needed to <br /> support an ERP permit modification(less modeling efforts). <br /> Task 3 (NEW): SCADA Coordination and Electrical Considerations <br /> As the ongoing projects have progressed through preliminary design, it has become <br /> apparent that an overall SCADA control system would be needed to monitor and operate <br /> the evaporation system, leachate storage tank (including pumps and water level <br /> transducers)and the updated landfill gas skid.The landfill is not currently equipped with a <br /> SCADA system, but the underlying fiber optic network needed to support a new SCADA <br /> system is in place. This task will include coordination with each project design team, the <br /> County's third-party SCADA integrator, and the equipment suppliers to facilitate the <br /> development of a SCADA system for the landfill. This task does not include design or <br /> integration services for the SCADA system. <br /> Page 3 of 7 <br />
