EXHIBIT #A <br />Work Order Number 8 <br />Industrial Wastewater Facility Permit Renewal <br />for <br />South Oslo Rd RO Water Treatment Plant <br />PROJECT UNDERSTANDING <br />Indian River County Utilities (IRCU) owns and operates a reverse osmosis (RO) water <br />treatment plant currently rated at 8.57 mgd maximum daily flow with an industrial <br />wastewater facility permit for demineralized concentrate disposal rated for 1.2 mgd <br />average daily flow, or 1.5 mgd maximum daily flow. The existing industrial wastewater <br />facility permit 31-FL0037940-006 expires May 6, 2017, and IRCU desires to renew the <br />operating permit in a timely manner. The renewal application and fees are due to be <br />submitted to FDEP Southeast District 180 days in advance, or by November 7, 2016. <br />The facility includes a new Algal Turf Scrubber system which includes up to 10 mgd of <br />stormwater pumped from South Relief Canal, comingled with RO plant concentrate which <br />trickles over a 4.6 acre treatment area prior to discharging to Sub -Lateral J- l canal. Various <br />monitoring locations throughout the treatment system are included with monthly and/or <br />quarterly monitoring. A 1.15 acre final polishing man-made wetland is used to treat the <br />ATS treated blend water before discharging to the Sub -Lateral J -I canal. A return (recycle <br />forcemain) allows reuse of effluent to hydrate the ATS in the event South Relief canal <br />supply water is not available for use. All surface waters' used for stormwater supply and <br />discharge of treated effluent are considered Class III fresh surface water, and therefore <br />require freshwater species (fathead minnows & daphnia water fleas) for chronic toxicity <br />testing. <br />The following scope of services consists of preparing and submitting an operating permit <br />renewal and responding to requests for additional information from the Florida Department <br />of Environmental Protection. <br />SCOPE OF SERVICES <br />The scope of services will consist of collecting and reviewing the existing operating data <br />since the last renewal (5 -years) and implementation of the Algal Turf Scrubber (ATS) <br />system, preparation and submittal of permit application including existing information <br />furnished by IRCU which will be updated as part of the application package, concentrate <br />water quality, and responding to FDEP requests for additional information (RFI). <br />Consultant will attend a kick-off meeting to discuss the operation of the new treatment <br />system since the previous permit renewal, collect data, and discuss potential revisions to <br />the permit through the application renewal. Consultant will conduct a site visit with <br />operations staff to review the operation of the existing ATS and stormwater pump station, <br />KAWPB Civil\044572030 - IRCU Oncall\Scope\South County Demineralization Permit Renewal 2016 REV2.docx <br />Page 1 of 3 <br />138 <br />
