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 ATTACHMENT "A" INDIAN RIVER COUNTY DEPARTMENT OF UTILITY SERVICES CENTRAL WWTP & REGIONAL SLUDGE PROCESSING FACILITY PROCESS & ODOR STUDY SCOPE OF SERVICES I.

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 Task 2 - Source Sample Collection and Analysis of Air Samples A. Using the existing design data and drawings, PBS&J will develop and conduct a source - sampling program that will seek to measure odor and sulfide emissions from the sources considered most important. Grab samples will be collected to measure odor emissions. Gas chromatographic/mass spectrometer (GC/MS) technique will be used to measure common reduced sulfur compounds as indicated in the sample analysis form included at the end of the scope. B. It is assumed that the sampling program will involve one sampling event. The sampling event will occur to measure existing emissions, in order to establish an estimate of emissions before certain improvements are made to the existing facilities. The sampling event will consist of one day of travel and equipment set-up and sample collection. No more than ten(10) samples will be collected and analyzed for sulfide compounds and odor characterization during the sampling event The number and location of samples are estimated as follows. Sample Event No. 1 Sample Sample Location Number Type Headworks Odor 2 Point Control System Grit Dumpster I Grab Upstream of Screens 1 Grab Anaerobic Tank 2 Grab First Anoxic Tank 2 Grab Sludge Scrubber 1 Point By the RIBS 1 Grab Comments In and out - durint; normal operation None Influent Box Inlet/outlet Inlet/outlet Scrubber Discharge Sample at the boundary C. The County will assist PBS&J during the set-up and sampling by operating all equipment, systems and processes in a normal manner. The County will also facilitate access to locations to be sampled. Task 3 — Odor Data Evaluation A. PBS&J will use the collected emission data to estimate the mass sulfur- and odor emission concentration for each sampled source. The sources will then be prioritized according to the estimated total mass emissions. B. PBS&J will also identify and evaluate appropriate air collection and odor control system for the each measured source at each WWTP. PBS&J will also evaluate potential controls or process modifications which might reduce odor emissions. Cost estimates will be developed for each odor control option evaluated. 2 Task 2 - Source Sample Collection and Analysis of Air Samples A.
