ATTACHMENT "A" INDIAN RIVER COUNTY DEPARTMENT OF UTILITY SERVICESAb CENTRAL WWTP & REGIONAL SLUDGE PROCESSING FACILITY PROCESS & ODOR STUDY SCOPE OF SERVICES I . PROJECT DESCRIPTION The West Regional Wastewater Treatment Plant (WRWWTP) is located at 8405 8th Street Vero Beach , FL 32960 . Construction on the West Regional Wastewater Treatment Facility expansion begun in July of 2007 and completed in May of 2010 .. The facility includes the a pretreatment structure with two (2 ) screens , and grit chambers and a 1000 CFM odor control system , a 5 - stage Biological Nutrient Removal (BNR ) system reusing the existing tankage and adding new tankage , conversion of the system to use diffused air, adding two additional clarifiers with final total of four, three new effluent filters final total of four, additional chlorine contact basins , additional rotary drum thickeners , a new single stage 2500 SCFM chemical scrubber for existing aerated sludge holding tanks , additional pumps , piping , chemical feed systems and controls . Although , the initial design and construction of the Wastewater Plant included Odor Control equipment for areas of the plant that normally are expected to generate odors , recently, adjoining neighbors have expressed concerns about odors from the plant . Subsequently, it is important to review the plant to determine quickly what additional modifications may be required to address the odor complaints . Indian River County has requested PBS &J to perform odor evaluation for the WRWWTP . The objectives of this project are to identify and evaluate the odor sources , c sample emissions of odorous compounds from facility and recommend appropriate methods for reducing odor emissions , if required . To achieve these objectives , PBS &J will utilize services of Jacobs Air Water Systems for collecting grab samples and Columbia Analytical Services , Inc for the sample analysis . The grab samples will be taken directly at the source where the emissions are expected at their highest level of detection . The sources will be prioritized to identify process parameters that might be responsible for the emissions , and evaluate potential approaches and costs for controls . II . SCOPE OF SERVICES The specific services and tasks to be provided by PBS &J are described as follows : Task 1 — Project Initiation and Data Collection A . Activities during this initial period will focus upon gathering and compiling existing data related to the operation of the wastewater treatment processes . Influent quality data ( since the start- up) will be collected and evaluated , The collected information and data will be reviewed and evaluated for relevant information 1
