PROJECT DESCRIPTION The objective of this project is to implement certain odor control improvements at the Indian River County ( IRC ) South WWTF . The basis for odor control improvements at the South WWTF will be indirect inference from the Central WWTF Odor Control Study and engineering judgment by IRC staff and PBS&J , absent any site specific testing for concentrations of mass emissions of odor compounds . PBS &J did conduct a site visit of both the South WWTF in April 2002 to observe the areas of potential odor emissions . For the purposes of preparing a scope of work , schedule and budget for this project , it is assumed that the design and permitting will be performed concurrently with , and in addition to , the Central WWTF and Regional Sludge Facility ( RSF ) project and that construction of odor improvements at the Central WWTF , RSF & the South WWTF will be performed via a single construction contract . II . SCOPE OF SERVICES The specific services and tasks to be provided by PBS &J are described as follows : Task 1 - Consultation with IRC Staff for County Implementation of Certain Odor Improvements Certain odor improvements are to be implemented via quotes from existing County contractors to IRC staff. PBS &J will support this effort by providing telephone consultation , periodic site visits , sketches , abbreviated technical specifications , and other technical support as detailed in the following tasks . It is understood from IRC staff that the following improvements described in PBS &J 's Odor Control Study have already been completed (or will be completed by IRC staff) and do not require further assistance from PBS&J : 0 Addition of gaskets on the headworks structure for the South WWTF CAF/bw/C:\Documents and Settings\ct7137\Loca1 Settings\Temporary Internet Files\OLK9F\ATTACHMENT A TO South WWTF Scope 3-25-03.doc Last Revised 5/4/2003 9: 04 AM 1 ATTACHMENT A INDIAN RIVER COUNTY DEPARTMENT OF UTILITY SERVICES SOUTH WASTEWATER TREATMENT FACILITY ODOR CONTROL IMPROVEMENTS SCOPE OF SERVICES (Continued) Task 1 . 1 - Headworks Scrubber Process Improvements The South WWTF utilizes a chemical scrubber to control odor emissions from the headworks process . Certain improvements to the operation and control of these scrubber processes may further improve scrubber efficiency . IRC staff will self perform all such improvements to the headworks scrubber system . PBS &J will provide sketches and other consultation to IRC staff in support of this effort up to a budget limit of 8 hours . Task 1 .2 - South WWTF Caustic Soda and Sodium Hypochlorite Storage and Feed Facilities IRC staff will procure the caustic soda and sodium hypochlorite feed systems for the South WWTF aerobic digester scrubber system to be installed by one of the County's existing contractors . PBS&J will provide sketches and other technical assistance to IRC staff up to a budget limit of 84 hours . Task 2 - Final Design IRC staff intends that certain odor control improvements be bid and constructed by a general contractor under the same construction contract as that for the Central WWTF & RSF odor improvements . PBS &J will prepare the contract documents to supplement those prepared under the Central WWTF & RSF odor control improvement project as detailed in the following tasks . For budgeting purposes , the following is a list of anticipated construction plans to be included in this final design effort : G - 1 South WWTF Site Plan C- 1 South WWTF Grading and Drainage S- 1 Structural Plans , Sections and Details M- 1 South WWTF Anoxic Basin Cover Plan , Sections and Details M -2 South WWTF Anoxic Basin Duct and Biofilter Plan , Sections and Details M-3 South WWTF Aerobic Digester Cover Plan , Sections and Details M-4 South WWTF Aerobic Digester Scrubber System Plan , Sections and Details M-5 South WWTF Aerobic Digester Sections and Details M-6 South WWTF Aerobic Digester Sections and Details CAF/bw/C:\Documents and Settings\ct7137\Loca1 Settings\Temporary Internet Files\OLK9F\ATTACHMENT A TO South WWTF Scope 3-25-03. doc Last Revised 5/4/2003 9:04 AM 2 ATTACHMENT A INDIAN RIVER COUNTY DEPARTMENT OF UTILITY SERVICES SOUTH WASTEWATER TREATMENT FACILITY ODOR CONTROL IMPROVEMENTS SCOPE OF SERVICES (Continued) HVAC- 1 South WWTF Screening Dumpster Area Ventilation Plan , Sections and Detail E- 1 South WWTF Electrical Site Plan E-2 South WWTF Single Line Diagram E-3 South WWTF Biofilter Electrical Plan and Details E -4 South WWTF Aerobic Digester Scrubber Electrical Plan E-5 South WWTF Aerobic Digester Electrical Details E-6 South WWTF MCP Layout I - 1 South WWTF MCP PLC Input Schematic Diagram Task 2 . 1 - Construction Plans - South WWTF Anoxic Basin Covers and Odor Control PBS&J will prepare construction plan sheets for the addition of aluminum or fiberglass covers for the South WWTF anoxic basins . PBS &J will prepare construction plan sheets for the addition of a modular biofilter and associated duct, blower, electrical and controls , for the covered anoxic basins . Task 2 .2 - Construction Plans - Improved Ventilation for Screenings Dumpster Area - South WWTF PBS &J will prepare construction plan sheets for improvements to the ventilation system at the South WWTF screenings dumpster area such that the doors can remain closed . The improvements will include duct that will be routed to the anoxic basin biofilter. Task 2 . 3 - Construction Plans for South WWTF Aerobic Digester covers and Scrubber System PBS &J will prepare construction plan sheets for the addition of aluminum or fiberglass covers and associated odor control scrubber. Absent any site-specific odor emission data , IRC and PBS &J agree that the basis of scrubber design shall be a two-stage chemical scrubber with caustic and sodium hypochlorite used for both stages . Construction plans will include a concrete foundation for the scrubber system and electrical and instrumentation drawings . PBS &J will provide technical support to IRC staff to self perform installation of the caustic soda and sodium hypochlorite storage and feed systems as described in Task 1 . 2 . Task 2 . 4 - Specifications PBS &J will prepare additional technical specifications related to the project and will incorporate County standard "front-end " ( Division 0- 1 ) specifications .
