Jerry L. Maxwell February 6, 2007 Page 2 With new alternative water supplies serving the region since 2002, Tampa Bay Water met the objectives of the Partnership Agreement by reducing groundwater pumping from the 11 regional wellfields below the 2002 cutback requirements. Configuration I of the Master Water Plan is expected to meet the region's water needs through approximately 2012. Tampa Bay Water continues to investigate new projects to supply its Members in 2012 and beyond. On December 15, 2003, the Board approved moving forward with the Downstream Augmentation Project, the Mid-Pinellas Brackish Water Desalination Project, and the Crystals International Water Supply Project. The Downstream Augmentation Project is part of the Tampa Bay Regional Reclaimed Water and Downstream Augmentation Project, and is subject to reporting requirements under a separate co-funding agreement. On February 28, 2005, the Board placed the Mid-Pinellas Brackish Water Desalination Project on hold due to increasing project costs pending outcome of the Downstream Augmentation NPDES permitting. In June 2006, the Board approved adding the Downstream Enhancements Project to the list of projects being considered for future water supply. The Board also continues to pursue the Downstream Augmentation and Crystals/Plant City water supply projects. BACKGROUND: In June 1998, the Tampa Bay Water Board of Directors approved the submittal of our New Water Plan to SWFWMD. On August 25, 1998, SWFWMD's Governing Board unanimously approved the New Water Plan. Subsequently, in accordance with Section 2.J of the Partnership Agreement, Tampa Bay Water continues to submit quarterly and annual progress reports to SWFWMD that contain current information on project scheduling and funding for the last Partnership Agreement project.

OVERVIEW In 1998, Tampa Bay Water and its Member Governments (Hillsborough, Pasco and Pinellas counties and the cities of New Port Richey, St. Petersburg and Tampa) committed to developing new sources of water that would produce at least 85 million gallons per day (mgd) by the end of 2007. In addition to developing new supplies, the agency committed to reducing groundwater pumping at 11 regional wellfields in the Northern Tampa Bay region. This commitment was written in the contracts that created Tampa Bay Water as well as in the Northern Tampa Bay New Water Supply and Groundwater Withdrawal Reduction Agreement (Partnership Agreement) with the Southwest Florida Water Management District (the District). Partnership Agreement As approved on May 14, 1998, the Partnership Agreement between Tampa Bay Water, its members and the District includes the following key objectives: development of new water supplies, phased reduction of groundwater withdrawals from the existing 11 wellfields in Northern Tampa Bay, financial assistance from the District for new water supply development, and water conservation. The phased reductions included in the Agreement specify combined production from the 11 wellfields limited to an average daily quantity of 158 mgd on a running 36-month basis through December 31, 2002, reduced to 121 mgd on a running 12-month basis as of 2003. As of December 31, 2007, the permitted annual average quantity from the 11 wellfields shall be further reduced to 90 mgd. Section 2.A. of the Partnership Agreement requires Tampa Bay Water to prepare and submit to the District a New Water Plan that describes the proposed water supply projects that, upon construction, will provide at least 85 mgd of new supply to the region by the end of 2007. In August 1998, the District Governing Board unanimously approved Tampa Bay Water's New Water Plan. Section 2.J. of the Partnership Agreement requires submittal of quarterly and annual New Water Plan update reports to the District. Section 2.J. requires that annual reports be submitted to the District that describe in detail the progress that has been made toward implementation of the approved New Water Plan until the projects are constructed and fully operational. The following chart shows that only one project covered by the Partnership Agreement remains in construction: New Water Plan/Master Water Plan Project Enhanced Surface Water System Alafia River Pump Station Tampa Bypass Canal/Hills borough River Pump Station C.W.

The only project remaining under construction, the Plant, is scheduled for completion prior to the 2007 pumping cutback milestone. This remaining Partnership Agreement project is the only project in the New Water Plan report. With new alternative water supplies serving the region since 2002, Tampa Bay Water met the objectives of the Partnership Agreement by reducing groundwater pumping from the 11 regional wellfields below the 2002 cutback requirements. Configuration I of the Master Water Plan is expected to meet the region's water needs through approximately 2012. Tampa Bay Water continues to investigate new projects to supply its members in 2012 and beyond. On December 15, 2003, the Board approved moving forward with the Downstream Augmentation Project, the Mid-Pinellas Brackish Water Desalination Project, and the Crystals International Water Supply Project. The Downstream Augmentation Project is part of the Tampa Bay Regional Reclaimed Water and Downstream Augmentation Project, and is subject to reporting requirements under a separate co-funding agreement. On February 28, 2005, the Board placed the Mid-Pinellas Brackish Water Desalination Project on hold due to increasing project costs pending outcome of the Downstream Augmentation NPDES permitting. Partnership Funding Under the Partnership Agreement, the District is providing $183 million of ad valorem tax revenues from the region to offset the cost of developing new water supply projects. These funds are to be used for projects that the District deems "eligible", and shall be used for "eligible" project costs. Eligible project costs are identified in the Agreement as those for design, engineering and construction. Five of the Board-approved Master Water Plan projects are eligible for District co-funding: the Enhanced Surface Water System,, North-Central Hillsborough Intertie, Brandon/South-Central Connection and Loop 72 Transmission Main. The Enhanced Surface Water System is eligible for a maximum co-funding of $120 million. The Tampa Bay Seawater Desalination project is eligible for a maximum co-funding of 90 percent of the total capital cost up to $85 million. The North-Central Hillsborough Intertie and Brandon/South-Central Connection are each eligible for 50 percent District co-funding. Tampa Bay Water/New Water I'lan Quarter^ Riport/December 2006

TAMPA BAY SEAWATER DESALINATION (Remediation Phase) The facility is located by Tampa Electric Company's Big Bend Power Plant near Apollo Beach on Tampa Bay. Upon remediation, this plant will be capable of providing up to 25 million gallons per day (mgd) and could be expanded in the future to 35 mgd capacity. Tampa Bay Seawater Desalination is the largest seawater desalination plant in North America. The project was originally developed using a Design/Build/Own/Operate/Transfer (DBOOT) procurement method. Due to financial difficulty experienced by the DBOOT's engineering, procurement, construct (EPC) contractor, Tampa Bay Water elected to purchase the facility in May 2002 from the developer. In November 2004, die Tampa Bay Water Board approved a Construction Completion Agreement and an Operations, Maintenance and Management Services Agreement with American Water-Pridesa LLC.
