Com COOPERATING ORGANIZATIONS : Indian River County Public Works , Indian River Farms Water Control District, City Of Vero Beach , St. Johns River Water Management District PROJECT ABSTRACT: A large treatment structure will be constructed in the Main Relief Canal in Vero Beach that utilizes a pumped sedimentation sump and a series of self- cleaning bar screens to remove suspended solids and floating vegetative debris from canal water flowing to the Indian River Lagoon . The structures are designed to treat 294 cfs draining from a 21 , 705-acre basin that is 50% urban and 50% agricultural . The self- cleaning fixed bar screens will utilize a traveling rake system to remove large masses of vegetative debris such as hyacinths , water lettuce , duckweed and grasses and floating trash before the water enters the Indian River Lagoon. A sedimentation sump preceding the bar screens will collect settleable solids that will periodically be pumped out by operations personnel . The project is anticipated to reduce Total Suspended Solids (TSS) by 45% (or 906 , 000 lbs. per year) , Total Phosphorus by 36% (or 11 ,500 lbs. per year), and Total Nitrogen by 23% (or 46 , 800 lbs . per year). A monitoring program will be conducted to accurately assess the removal efficiency of this treatment system. A public education and awareness program will be incorporated with the construction project to help reduce trash and vegetative debris input to the drainage system . PROJECT LOCATION AND WATERSHED CHARACTERISTICS: The Indian River Farms Water Control District ( IRFWCD) in Indian River County, Florida , is an area over 53,000 acres that is drained by an extensive 300 mile network of man-made canals . The 21 , 705 acre Main Relief Canal basin is approximately 50% urban and 50% agricultural . The IRFWCD discharges into the Indian River Lagoon , an Estuary of National Significance. In the East Indian River County Master Stormwater Management Plan , a pollutant loading analysis showed that the three discharge canals of the IFRWCD convey huge amounts of suspended solids, nutrients , and floating vegetative debris into the lagoon , seriously degrading estuarine habitat. The canals also transport tremendous quantities of human- generated trash (Styrofoam cups, plastic, bottles, etc. ) into the Lagoon . The proposed location of the Main Relief Canal treatment structure is west of US Highway 1 and the FEC railroad near the Vero Beach airport. Construction will take place within the public right-of- DEP Agreement No. G0182, Attachment A- 1 , Page 1 of 12 way of the IRFWCD as authorized by a Memorandum of Understanding between Indian River County and the Water Control District.

The IRFWCD discharges into the Indian River Lagoon , an Estuary of National Significance and a St . Johns River Water Management District (SJRWMD) Surface Water Improvement and Management (SWIM ) program priority water body. In the East Indian River County Master Stormwater Management Plan (Master Plan ), a pollutant loading analysis showed that the three discharge canals of the IFRWCD convey large amounts of suspended solids , nutrients , and floating vegetative debris into the lagoon , seriously degrading estuarine habitat. The canals also transport tremendous quantities of human-generated trash (Styrofoam cups, plastic, bottles, etc. ) into the Lagoon . Treatment alternatives were investigated in the Master Plan . It was recommended that sediment and floating debris collection systems be used to effect a significant reduction in muck contributing solids, nutrients , floatables and trash into the Lagoon . Several of these BMPs were determined to be well-suited for placement within the limited space available in the existing canal rights-of-way. The two general types of improvements which appeared to be effective given the existing conditions were floating debris capture systems and structural pollution control devices. The need for this project is described in the November 1996 " Indian River Lagoon Comprehensive Conservation and Management Plan" under the Water and Sediment Quality Improvement section . Recommendations for large drainage systems, such as the IRFWCD, are found in Action FSD- 12, Freshwater and Stormwater Discharges Action Plan . The 2002 IRL SWIM Plan Update discusses the IRFWCD and the need to reduce TSS and nutrients in Chapter 5, page 133 . A major concern stated in the SWIM Plan is the total phosphorus loading from the IRFWCD being higher than that from the Turkey Creek basin which is 1 . 5 times larger in area . Methods to treat or control pollution from stormwater runoff (BMPs) have traditionally included practices that are typically land intensive (dry retention areas, wet detention ponds) and have low maintenance requirements. However, as land has become scarcer and more valuable in Florida , efforts have also been focused on treatment technologies that DEP Agreement No. G0182, Attachment A- 1 , Page 2 of 12 are not as land intensive . Many of the more compact systems are adaptations of domestic and industrial wastewater treatment components . These active systems , which often include electrical or mechanical components , have come to be known as "structural" pollution control devices ( PCDs ) . They have a higher operation and maintenance requirement than passive systems. In light of extremely high construction and energy costs together with the knowledge of the tremendous pollution caused to the Indian River Lagoon by the Main Relief Canal , Indian River County is designing a stormwater treatment system that is simple , easy to construct, easy to operate , easy to maintain , requires minimal power cost, and provides substantial pollutant removal capability. This system is referred to herein as the bar screen system and it will use two sets of six self-cleaning bar screens in series to remove solids from the canal . The developers of this system are in the process of applying for a U . S . patent for the system. It will also incorporate a simple sedimentation basin upstream of the bar screens to collect soil particles that are transported along the canal bottom by storm flows . The collected sediment will be removed from the sedimentation basin sump by two horizontal shaft belt-driven centrifugal trash pumps . The design is unique because it consists of bar screens in series rather than using only a single set. Installations using only a single set of bar screens are in operation in the South Florida Water Management District (SFWMD) and other locations in Florida and nationwide. IRC staff visited several SFWMD installations and attests to the efficient and simplistic operation of these bar screening systems . In the IRC system , canal water will be diverted into an off-line treatment channel that will contain the bar screening system . The first set of bar screens will have one-inch openings and will remove all particles one-inch in diameter or larger. The removed solids will be deposited by the self-cleaning screens onto a conveyor that will dump them into a waste collection container for ultimate disposal in the IRC landfill . The first set of bar screens will be followed by a second set having 1 /8-inch openings. The second set of self-cleaning bar screens will also deposit its solids onto a conveyor that dumps into another waste collection container. The system has the following attributes : • Horsepower Requirements - Horsepower requirements are minimal . There will be 12 self-cleaning bar screens, each with a 1 /8 Hp motor. There will be two 3 Hp conveyors and two 5 Hp sedimentation removal system pumps. Therefore, the total required horsepower is 17. 5 Hp . Normally, only the bar screens and conveyors will be operating , representing a total 7. 5 Hp . System operating personnel will manually operate one 5 Hp sediment pump at a time for short periods. • Simplicity of Design — The self-cleaning bar screens have proven themselves to be simple and effcient. SFWMD has operated some for over 7 years, 24 hours per day, 7 days per week with no downtime due to equipment failure . The design 's most complicated piece of equipment is the conveyor system and it is easily accessible and easy to repair. The aboveground sediment removal pumps will be located so they are also easily accessible . The bar screen system controls will be the simplest possible . Controls are as follows: ( 1 ) The sediment removal pumps will be manually operated with an "on-off' switch ; (2) The self-cleaning bar screens will be in operation 24 hours per day, 7 days per week. Each screen will have an "on-off' switch together with standard built-in safety controls. If a large object jams a screen , the screen will DEP Agreement No. G0182, Attachment A- 1 , Page 3 of 12 attempt to un-jam itself three times. If after the third try it is still jammed , the screen will shut down until it is manually restarted . If a conveyor fails , the set of bar screens associated with the conveyor will shut down . (3) Each conveyor will be operated 24 hours per day, 7 days per week and will have a simple "on-off' switch together with safety controls to shut the unit off in the event of a jam . A control system cannot be simpler than this design . • Ease of Operation and Maintenance — The bar screen system will be easy to operate and maintain . The self-cleaning bar screens are almost maintenance free and the other equipment is simple in design and easy to repair. • Pollution Removal Efficiency — It is very difficult to estimate the pollutant removal rates for the bar screen system. Sediment and other solids that are typically carried along the canal bottom during storm flows will deposit in the sedimentation basin and be removed daily or weekly as required , by the sediment removal pumps . Vegetation and trash will be removed by the bar screens . The scraping mechanisms on the self-cleaning bar screens travel very slow, approximately 28 inches per minute. This allows debris to accumulate on the screen before the next cleaning cycle. As debris accumulates , particles smaller than the bar screen opening will be trapped in the pile , effecting short- term removal of the smaller particles. In any event, all particles 1 /8-inch or larger will be removed with many particles smaller than 1 /8-inch being caught in the temporary mats and removed . Research indicates that in the canals , 25 percent of the total nitrogen (TN ) and 40 percent of the total phosphorus (TP) is associated with particulate matter, with the remainder being in the dissolved form . The particulate matter consists of settelable particles and plant material . Therefore, assuming that the pumped sedimentation basin and the bar screens will remove 90 percent of the TN and TP associated with particulate matter, the removal is estimated to equal 46 ,800 lbs per year TN and 11 , 500 lbs per year TP . With respect to total suspended solids (TSS), assume that the pumped sedimentation basin will remove approximately 75 percent of the TSS that a vortex treatment system would remove. Assume that a vortex system would remove 60 percent of the TSS in the canal water. Therefore, the sedimentation basin is estimated to remove 75 percent of that 60 percent, or 906 , 000 lbs per year from the Main Relief Canal . • Construction Cost — IRC estimates that the bar screen system will cost about $3.4 million . Therefore , it is clear that the bar screen system will provide the most effective use of IRC's limited construction funds . The system's simple design will be reflected in its ease of operation and maintenance. The cost savings realized by this design will allow IRC to construct other worthy stormwater pollution control projects and reduce pollution of the Indian River Lagoon . This one project provides a significant opportunity for Indian River County to make great strides in meeting the proposed TMDLs for this basin of the Indian River Lagoon and improving estuarine habitat and water quality for this segment of the Indian River Lagoon . DEP Agreement No. G0182, Attachment A- 1 , Page 4 of 12 PROJECT OBJECTIVE(S) : There are 17 segments of the Indian River Lagoon basin that were identified on the Florida Department of Environmental Protection ( DEP) 1998 303(d ) list as impaired by nutrients , dissolved oxygen , or chlorophyll a and were scheduled for TMDL development by June 30 , 2003 . All of these segments fall within the FL DEP Indian River lagoon Group 5 Basin and , as a result, were scheduled for TMDL development by FL DEP in September 2004 . The segments in Indian River County that will be addressed by this project are named South Indian River WBID 5003C, IRL Segments 16-20. The Main Relief canal basin is segment # 19 . Due to the extensive network of canals that carry stormwater runoff in this region , Indian River County is in a unique position to capture and treat a significant portion of its total runoff. The Main Relief Canal conveys approximately half of the total runoff from the Indian River Farms Water Control District to the Indian River Lagoon . The proposed bar screen system will remove a significant quantity of nutrients and muck contributing solids from canal discharges. (TSS=411 ,000 Kg per year, TN =21 , 200 Kg per year, TP= 5, 200 Kg per year) . Removing these nutrient loads will move the County closer to meeting the TMDLs for this segment of the lagoon . Specific Project Obiectives : ( 1 ) To demonstrate that a combination of treatment technology ( i . e. self-cleaning bar screens and pumped sedimentation sumps) can be used to effeciently remove large amounts of floating and suspended material from an existing canal . (2) To demonstrate that a large stormwater pollution control device if maintained on a regular basis, can remove significant amounts of pollutants. (3) To demonstrate that if large quantities of aquatic plant material and algae are removed from the system , then large amounts of nutrients (nitrogen and phosphorus) associated with that plant material and algae are also removed . PROJECT DESCRIPTION : The Indian River Farms Water Control District ( IRFWCD) in Indian River County, Florida is an area over 53,000 acres that is drained by an extensive network of man-made canals . The IRFWCD discharges into the Indian River Lagoon , an Estuary of National Significance and a St. Johns River Water Management District (SJRWMD) Surface Water Improvement and Management (SWIM) program priority water body. In the East Indian River County Master Stormwater Management Plan (Master Plan) , a pollutant loading analysis showed that the three discharge canals of the IRFWCD convey large amounts of suspended solids, nutrients, and floating vegetative debris into the lagoon . Treatment alternatives were investigated in the Master Plan . It was recommended that sediment and floating debris collection systems be used to effect a significant reduction in suspended solids , nutrients, and floatables into the Lagoon . This project is for the construction of a large treatment device on the Main Relief canal that utilizes self-cleaning bar screens and pumped sedimentation basins to remove solids and floating debris from canal water. The proposed location of the treatment facility is west of US Highway 1 and the FEC railroad near the Vero Beach airport. The project will be constructed within the publically owned right-of-way of the Indian River Farms Water Control District. Fixed bar screens will be integrated with a traveling rake to remove large masses of vegetative debris such as hyacinths , water lettuce, duckweed and grasses and floating trash before the water enters the vortex unit. In addition , the pumped sedimentation basin will remove settleable suspended sediments. Based on water quality data for the Main Relief Canal and a design flow rate of 294 cfs , the following annual pollutant load reductions are estimated : DEP Agreement No. GO 182, Attachment A- 1 , Page 5 of 12 TSS = 906, 000 lbs . TN = 46 ,800 lbs TP = 11 , 500. This one project provides a significant opportunity for Indian River County to make great strides in meeting the proposed TMDLs for this basin of the Indian River Lagoon . Self-cleaning screens are based on a concept that has been proven to be effective and has been in continuous operation for over seven years at a stormwater treatment area in West Palm Beach as part of the Everglades restoration project. The developers of the bar screen system are in the process of obtaining a U . S . patent for the system . It will utilize two sets of self-cleaning bar screens in series that will remove all particles 1 /8-inch and larger and some smaller particles due to matting effects . The pumped sedimentation sump will collect settleable solids that will be periodically removed by operations personnel . If necessary, maintenance will occur on a daily basis to remove the solids collected by the screens and sedimentation basin . Indian River County understands that maintenance is the key to pollutant removal efficiency. Project design is expected to be complete in mid-September 2006 . Public Outreach : A stormwater education campaign will be initiated in concert with construction to heighten awareness of the canal drainage system and the pollution it carries to the estuary. The St. Johns River Water Management District's IRL License Plate program has authorized the funding of 100 metal 30" x 34" street signs to be erected at strategic locations throughout the drainage basin . The sign will picture the license plate snook and read : "All Canals Drain To Lagoon - No Trash !". Signs will be placed at intersections near major canals . Newspaper articles and brochures will link the new road signs with the construction of the Main Relief Canal pollution control structure. The County believes that a heightened public awareness through a highway and road signage program will reduce the pollutant loads to our constructed treatment facility for the Indian River lagoon . Effectiveness Monitoring : Project effectiveness monitoring will be conducted to demonstrate the pollutant loading reduction accomplished by the treatment facility. Two types of monitoring will be conducted . 1 ) to evaluate the effectiveness of the treatment system , composite grab samples will be collected from the stormwater that passes through the treatment facility during seven storm events. Samples will be collected at the influent point to the treatment facility and at the effluent side for comparison . 2) an additional assessment of the pollutant load reduction will be achieved by weighing and quantifying representative samples of the trapped material by the bar screens and the sedimentation basin . The representative samples of the trapped material will be analyzed for nutrient content on a dry weight basis . A continuously operating flow meter will allow for accurrate estimates of total volume treated . All trapped material removed from the facility will be weighed at the County landfill prior to disposal at the landfill . The County intends to keep daily records of flow and materials removed in order to demonstrate credit towards achieving the TMDL for this basin . A Preliminary Effectiveness Monitoring Plan has been included in this proposal as Attachment A.

For the purpose of this Grant, removals have been estimated using information presented in the " Final Preliminary Engineering Report - Vortex Treatment Units and Floating Debris Capture Equipment," November 2003, prepared for Indian River County by Environmental Consulting & Technology, Inc. The report states that 25 percent of the total nitrogen (TN ) is associated with particulate matter and that 40 percent of the total phosphorus (TP) is associated with particulate matter, with the remainder of these being in the dissolved form . The particulate matter consists of settelable particles and plant material . Therefore , assume that the pumped sedimentation basin and the bar screens will remove 90 percent of the TN and TP associated with particulate matter = 46, 800 lbs per year TN and 11 ,500 lbs per year TP. With respect to total suspended solids (TSS), assume that the pumped sedimentation basin will remove approximately 75 percent of the TSS that a vortex treatment system would remove . Assume that a vortex system would remove 60 percent of the TSS in the canal water. Therefore, the sedimentation basin is estimated to remove 75 percent of that 60 percent, or 906 , 000 lbs per year. A summary of the estimated removal for the proposed treatment system is presented in Table 1 : Table 1 - Estimated Pollutant Removal by the Proposed Treatment System in the Main Relief Canal (Post-construction loadings were extrapolated from the " Final Preliminary Engineering Report - Vortex Treatment Units and Floating Debris Capture Equipment, " for Indian River County, prepared November 2003 by Environmental Consulting and Technology, Inc. ) TSS TP TN Post-Construction 2,013, 000 lbs/year 32,000 lbs/year 208,000 lbs/year Estimated Removal 906 ,000 lbs/year 11 ,500 lbs/year 46 , 800 lbs/year 45 percent 36 percent 23 percent DEP Agreement No. GO 182, Attachment A- 1 , Page 7 of 12 OUTPUTS/DELIVERABLES : Task 1 - Surveying and Modeling .

Gates are opened an average of 20 times per year and left open approximately 20 % of the year. Typically a one-inch rainfall or greater will result in a gate opening and discharge to the IRL. Flow Measurements : Flow will be measured using ultrasonic or similar flow meters .

Representative samples will be periodically collected and analyzed for total phosphorus and total nitrogen on a dry- weight basis . The County will maintain a running log of the total weight of vegetative material removed by the treatment system . It will maintain a running total of phosphorus and nitrogen removed on a dry-weight basis. This information will be used to document credit towards achieving the TMDL for this basin . The Main Relief Canal has a continuous flow discharge to the Indian River lagoon that averages approximately 50 million gallons per day. During storm event periods radial DEP Agreement No. GO 182, Attachment A- 1 , Page 11 of 12 control gates are opened to release flood waters stored in approximately 150 miles of canal and ditch network in the 21 , 705 acre basin . Gate openings occur approximately 20 times per year and remain open 2 ,000 to 3 , 000 hours per year. Discharges following a gate opening can reach 400 cubic feet per second . Due to the characteristics of this unique discharge situation , the County proposes to collect frequent grab samples from the influent to the vortex unit and from the effluent. Flow will be continuously monitored so that a mass loading will be established from the concentration data following laboratory analysis of the samples (see parameter list above) . Since the focus is on particulate matter and its associated pollutants , we do not recommend the conventional automated sampler with the small intake tubing . The typical intake tubing associated with a sampler cannot pull a representative sample that contains the particulate load .
