approved by FDEP , the proposed permit modifications will provide additional flexibility that <br /> will enable the County to maximize the operational benefits of the generous investments that <br /> have already been made to preserve the Indian River Lagoon. The proposed project will provide <br /> the following changes/improvements : <br /> West Regional WWTF : <br /> 1 . Increase the permitted capacity of surface water discharge to the Lateral D Canal (D- 001 ) <br /> from 4 . 0 MGD to 6 . 0 MGD to match the current permitted plant capacity of 6 . 0 MGD . <br /> 2 . Increase the permitted discharge capacity of the wetland treatment/reuse system (R- 001 ) from <br /> 4 . 0 MGD to 6 . 0 MGD to match the current permitted plant capacity of 6 . 0 MGD . <br /> 3 . Increase the permitted discharge capacity from South Regional WWTF to the wetland <br /> treatment/reuse system (R-001 ) from 2 . 0 MGD to 4 . 0 MGD . <br /> 4 . A single instance of selenium was reported in last permit renewal application. This was likely <br /> sampling error as there were no other reported incidents of selenium before or after this single <br /> sample result. Because of this erroneous sample result, an Administrative Order (AO) was issued <br /> along with the current permit. As part of the permit modification application we will propose to <br /> resolve and remove the AO from the permit, by using subsequent and previous sample results to <br /> substantiate the closure of the Administrative Order. <br /> 5 . Quantify and obtain credit on the permit for the phosphorus and nitrogen treatment that <br /> occurs in the Egret Marsh and PC Main treatment systems that are downstream from the West <br /> Regional WWTF . Historical sampling data will be used to substantiate the credits . <br /> North RO Plant <br /> Quantify and obtain credit on the FDEP permit for the phosphorus and nitrogen treatment that <br /> occurs in the Spoonbill Marsh treatment system located downstream from the North RO Plant. <br /> Historical sampling data will be used to substantiate the credits . <br /> South RO Plant <br /> Quantify and obtain credit on the FDEP permit for the phosphorus and nitrogen treatment that <br /> will occur in the PC South treatment system that will be located downstream from the South RO <br /> Plant. Existing pilot study data will be used to substantiate the credits . <br /> County Wide Long Term Goal for Nitrogen and Phosphorus Reduction/Credit Banking <br /> The ultimate long term goal is to bank nutrient credits for the treatment of nitrogen and <br /> phosphorus in a county wide bank that could be utilized as necessary across all County permits . <br /> Eventually these credits could even be a source of revenue if and when FDEP implements a <br /> water quality credit trading program . These are long term goals because implementation will not <br /> be possible until FDEP (along with stakeholder input) quantifies basin wide goals for nutrient <br /> reduction. FDEP is currently developing Basin Management Action Plans (BMAP) that will <br /> identify specific strategies that will be used to achieve pollution reduction goals . These goals <br /> must then be translated into a maximum amount of pollution that each water body can receive . <br /> Credit banking/trading will be a challenging and long range mission, but if achieved will <br /> stimulate the provision of clean water by enabling emitters in our watershed to work together to <br /> reduce pollution of the Indian River Lagoon in a cost effective way . <br /> If approved by FDEP the proposed permit modifications above on the North RO Plant, South RO <br /> Plant, and West Regional WWTF permits will be a first step towards the ultimate goal of county <br /> wide credit banking and trading, as the County will begin archiving, in a format that is <br /> Page 2 of 4 <br />
