i <br />11 <br />Leachate quality will be compared to pretreatment standards of Indian River Co,.rnty <br />Utilities to identify any leachate characteristics that must be removed or reduced and/or <br />require rate surcharges. <br />G&R will also meet with Utilities Department representatives to discuss any <br />transportation or treatment issues regarding leachate. Any capacity restrictions in the <br />forcemain system to the West Regional WWTF will also be requested from the <br />Department. <br />Subtask 7.2 West Reuional WWTF Process Analysis <br />G&R based upon prior studies of loading on biological nitrogen and phosphorus removal <br />systems will conduct a process analysis of the West Regional WWTF to determine the <br />ability of the treatment facility to receive leachate based upon the quality and quantity <br />developed in Subtask 7.1. This analysis will also assume an increasing flow rate for raw <br />wastewater coating into the West Regional WWTF based upon flow increases provided <br />by Utilities Department staff. An upper flow limit for leachatc into the facility may be <br />adopted from this analysis. <br />Subtask 7.3 Pretreatment Options <br />G&R will evaluate the following pretreatment and leachate management options: <br />• Equali7ation and storage wlwo treatment <br />• Bioreactor <br />• Biological treatment (single train activated sludge) <br />• Membrane Process (one option) <br />• Evaporator Process in conjunction with LFG system <br />G&R will develop capital and annual O&M costs of each pretreatment option, It is <br />assumed that the County transmission system will be capable of transmitting the requited <br />flows as determined in Subtask 7.1. As part of the equaliaaition and storage option, G&R <br />will assume a truck load out option for emergencies. Also potential facilities outside of <br />Indian River County Utilities that might receive trucked Icachate from the landfill will be <br />presented along with the cost of such option. <br />G&R will present a recommended option for leachate management along with suggested <br />schedule for implementation of improvements. <br />Task 8.0 Recoverable Materials Market Survey <br />The G&R project team will perform a recovered materials market survey to identify <br />available local, state, and regional markets for fi dian River County rccyclables.
