Reingold, County Attorney EXHIBIT 1 TMDL PERMIT MODIFICATIONS at the SOUTH COUNTY RO PLANT, NORTH COUNTY RO PLANT, AND WEST REGIONAL WWTF GENERAL The Indian River Lagoon (IRL) is an important recreational and economic resource to the state and region. According to the St. Johns River Water Management District, the total estimated annual economic value of the lagoon is $3 . 7 billion, supporting 15 , 000 full and part-time jobs and providing recreational opportunities for 11 million people per year. For these reasons, among others , it was designated in the 1987 Surface Water Improvement and Management ( SWIM) Act as a priority waterbody in need of restoration and special protection. Rising levels of excess nutrients (nitrogen and phosphorus) in the IRL have become a real concern, as these excess nutrients can contribute to loss of sea grass beds, fish, dolphins, manatees, and hundreds of other species in what is considered the most biodiverse estuary in the United States . By dedicating millions of dollars to the Spoonbill Marsh, Egret Marsh, PC Main and the PC South Algal Turf Scrubber treatment systems, Indian River County has become a proactive leader in nutrient reduction, paving the way for other utilities throughout the State . As a result of the new treatment systems, IRC has significantly reduced the amount of excess nutrients (nitrogen and phosphorus) being discharged into the Indian River Lagoon by the County water and wastewater plants . The County has taken a strong stance in implementing projects that will create a "net positive environmental benefit" to the Indian River Lagoon, to the extent that IRC worked with FDEP to create for the first time, a new permit requirement for Spoonbill Marsh that defines a net positive environmental benefit as "an evaluation of nutrients in terms of a reduction in (a) concentration, (b) mass loading, and (c) biological impact of the discharge flowing into the Indian River Lagoon. " In simpler terms, the amount of excess nutrients being discharged from the County utility plants must be less than the amount of nutrients that naturally exist at the outfall into the Indian River Lagoon. The new systems are not only providing a "net positive environmental benefit", but they are providing substantial additional treatment which results in an improvement of the source lagoon water quality. Although the payback for these projects has already been realized in considerable environmental benefits and through compliance with the current permits, there are potential benefits that have not yet been realized. The current FDEP permits are overly constraining . We are proposing to work with FDEP to obtain credit on the plant permits for the millions of dollars spent by IRC to remove thousands of pounds of nitrogen and phosphorus from the IRL . In the last month alone, 905 lbs of nitrogen and 337 lbs of phosphorus were removed by the Egret Marsh, PC Main and Spoonbill Marsh treatment systems . This would equate to over 10 ,000 lbs per year of nitrogen and 4 , 000 lbs per year of phosphorus . The County has exhaustive data to support an increase in nitrogen and phosphorus limitations on the South County RO Plant industrial waste permit (FDEP Permit Number 3 1 -FL003 7940), North County RO Plant NPDES discharge permit (FDEP Permit Number 3I -FL0166511 - 004) , and the West Regional Domestic Waste Permit (FL0041637 -006) . To obtain credit on the permits for the nutrient reductions, historical sampling and existing pilot study data must be analyzed and summarized in a report for each plant, along with an FDEP permit application. If Page 1 of 4 approved by FDEP , the proposed permit modifications will provide additional flexibility that will enable the County to maximize the operational benefits of the generous investments that have already been made to preserve the Indian River Lagoon. The proposed project will provide the following changes/improvements : West Regional WWTF : 1 . Increase the permitted capacity of surface water discharge to the Lateral D Canal (D- 001 ) from 4 . 0 MGD to 6 . 0 MGD to match the current permitted plant capacity of 6 . 0 MGD . 2 . Increase the permitted discharge capacity of the wetland treatment/reuse system (R- 001 ) from 4 . 0 MGD to 6 . 0 MGD to match the current permitted plant capacity of 6 . 0 MGD . 3 . Increase the permitted discharge capacity from South Regional WWTF to the wetland treatment/reuse system (R-001 ) from 2 . 0 MGD to 4 . 0 MGD . 4 . A single instance of selenium was reported in last permit renewal application. This was likely sampling error as there were no other reported incidents of selenium before or after this single sample result. Because of this erroneous sample result, an Administrative Order (AO) was issued along with the current permit. As part of the permit modification application we will propose to resolve and remove the AO from the permit, by using subsequent and previous sample results to substantiate the closure of the Administrative Order. 5 . Quantify and obtain credit on the permit for the phosphorus and nitrogen treatment that occurs in the Egret Marsh and PC Main treatment systems that are downstream from the West Regional WWTF . Historical sampling data will be used to substantiate the credits . North RO Plant Quantify and obtain credit on the FDEP permit for the phosphorus and nitrogen treatment that occurs in the Spoonbill Marsh treatment system located downstream from the North RO Plant. Historical sampling data will be used to substantiate the credits . South RO Plant Quantify and obtain credit on the FDEP permit for the phosphorus and nitrogen treatment that will occur in the PC South treatment system that will be located downstream from the South RO Plant. Existing pilot study data will be used to substantiate the credits . County Wide Long Term Goal for Nitrogen and Phosphorus Reduction/Credit Banking The ultimate long term goal is to bank nutrient credits for the treatment of nitrogen and phosphorus in a county wide bank that could be utilized as necessary across all County permits . Eventually these credits could even be a source of revenue if and when FDEP implements a water quality credit trading program . These are long term goals because implementation will not be possible until FDEP (along with stakeholder input) quantifies basin wide goals for nutrient reduction. FDEP is currently developing Basin Management Action Plans (BMAP) that will identify specific strategies that will be used to achieve pollution reduction goals . These goals must then be translated into a maximum amount of pollution that each water body can receive . Credit banking/trading will be a challenging and long range mission, but if achieved will stimulate the provision of clean water by enabling emitters in our watershed to work together to reduce pollution of the Indian River Lagoon in a cost effective way . If approved by FDEP the proposed permit modifications above on the North RO Plant, South RO Plant, and West Regional WWTF permits will be a first step towards the ultimate goal of county wide credit banking and trading, as the County will begin archiving, in a format that is Page 2 of 4 acceptable to FDEP (monthly Discharge Monitoring Reports), the nutrient reduction that is being attained by Indian River County . When FDEP has established basin wide goals , IRC will have the historical data necessary to validate a request for county wide nitrogen and phosphorus credits . SCOPE OF SERVICES We propose to complete the above described work in two separate phases as follows : Phase I — Preliminary Coordination with FDEP MBV Engineering will establish the initial groundwork that will be necessary to achieve an understanding with FDEP of the desired outcome . Through this preliminary coordination, MBV Engineering will evaluate the feasibility of Phase II and determine what will be required to obtain the proposed permit modifications . It is anticipated that a significant amount of coordination will be required with both the Central and Southeast Districts since FDEP jurisdictional boundaries have changed since the issuance of the Spoonbill Marsh, Egret Marsh and PC South construction permits . Phase I will include at least one face to face meeting with representatives from both the Central and Southeast Districts to facilitate the transfer of knowledge regarding the history of the North RO Plant, South RO Plant and West Regional WWTF discharge permits and treatment systems . Phase II — Formal Permit Modifications Based upon our knowledge and understanding of the rules and regulations of the governing agencies, the following scope for Phase II is anticipated; however, it could change depending on the information obtained in Phase I. Tabulation and Analysis of Plant Operating Data MBV Engineering, Inc . will tabulate and analyze historical plant operating data and sampling records , which document the removal of phosphorus and nitrogen from the South County RO Plant, North County RO Plant, and the West Regional WWTF . Analysis results will be summarized in a report that will be provided along with the applications to provide substantiation for the permit modification request. Preparation and Submittal of FDEP Permit Renewal Application MBV Engineering, Inc will prepare and provide to FDEP and IRCU, the applications and forms necessary to revise the West Regional WWTF operating permit, the North County RO and the South County RO NPDES Industrial Wastewater Discharge Permits . Preparation of FDEP Required Backup Documentation MBV Engineering, Inc . will provide to FDEP and IRCU the following backup documents , maps , and diagrams that are necessary to obtain the revised permits . 1 . Process Flow Diagrams 2 . Site Plans 3 . Location and Vicinity Maps Preparation of Capacity Analysis Reports for each plant Page 3 of 4 MBV Engineering, Inc . will prepare a Capacity Analysis Report that must be submitted along with each permit application. These reports will document our analysis and evaluation of historical flows and discharges from each plant. SCHEDULE It is estimated that the tasks mentioned in the Phase I scope above will be completed within approximately 45 days of work order approval .
