  2. Presentation Outline • Overview of Long-Term Plan • Status of Project-Level Activities • Revisions to the Long-Term Plan • Remaining Challenges and Uncertainties • Peer Review Comments

  3. Overview of Long-Term Plan • Developed in early 2003 by technical staff of SFWMD, FDEP, EAAEPD and other stakeholders • Goal: Achieve compliance with state water quality standards including the phosphorus criterion in the EPA by 12/31/06 • Extensive peer review and public input

  4. Plan Addresses: • Seven Everglades Construction Project (ECP) Basins • Six Everglades Stormwater Program (ESP) Basins

  5. Overview of Long-Term Plan • BAPRT in 2003 amended EFA • BAPRT in phosphorus rule adopted by the ERC in 2003 • Included in December 2003 application to FDEP for permit modification • Projected costs of $445 million through FY2016 (October 27, 2003 version; prior to recent major revisions adding over $200 million)

  6. Three Primary Components • Pre-2006 Projects • Process Development and Engineering • Post-2006 Strategies

  7. Pre-2006 Projects • ECP Basins • Additional STA compartmentalization • Vegetation management and conversion • Operational refinements • ESP Basins • Source controls (BMPs) • Operational adjustments • Integration with CERP

  8. Process Development and Engineering (PDE) 1 of 2 • Maintain and improve BMP performance in EAA and C-139 • Continue and expand STA optimization research, monitoring and model development • Improve reliability of estimated STA inflow volumes and phosphorus loads • Refine estimated impact of CERP projects on basin discharges and phosphorus loads • Determine relationship between quality of water discharged into, and water quality within, the EPA

  9. Process Development and Engineering (PDE) 2 of 2 • Will continue through FY 2016, but majority of effort complete in FY 2009 • Comprehensive report to Governor and Legislature due 12/31/08 • Status and progress of LTP • Recommend additional measures if needed to achieve water quality goals

  10. Post-2006 Strategies 1 of 2 • Adaptive implementation of additional water quality improvement measures • Based on actual STA performance and results of PDE effort • $36 million in recommended funding

  11. Post-2006 Strategies 2 of 2 • Implement steps to accelerate recovery of impacted areas in the EPA • Combination of fire, hydroperiod, possibly herbicide and transplanting desirable vegetation • Completion of hydropattern restoration works associated with STAs • $45.3 million in recommended funding

  12. Status of Project-Level Activities • Similar to last year, updates for most Long-Term Plan projects appear in other chapters of the SFER Volume I • ESP Basin Projects – Ch. 3 • Source Control Projects – Ch. 3 • STA Performance & Enhancements – Ch. 4 • Accelerate Recovery of Impacted Areas – Ch. 6 • Refer to Table 8-1 for reference chapters • Status of 8 Long-Term Plan projects presented in Chapter 8

  13. Status of Project-Level Activities • 1. Continued Development and Refinement of DMSTA • Dynamic Model for Stormwater Treatment Areas (Walker and Kadlec, 2002) • Model used to predict future performance of the STAs with enhancements and CERP reservoirs • Objective is to increase certainty in accuracy of model predictions • FY 2005 tasks completed by USDOI and USACE • DMSTA2 released in FY 2005

  14. Status of Project-Level Activities • 2. Water Quality Impacts of Reservoirs • Objective is to assist CERP PDTs in acquisition and analysis of calibration data sets for reservoir water quality models • EAA Storage Reservoir CERP project of particular interest since it will discharge to ECP STAs • FY 2004 tasks completed: • Physical, chemical and vegetative data analyzed • FY 2005: Transformation of data for use in calibration of a reservoir water quality model • Provided to Dr. Bill Walker for use in developing reservoir module of DMSTA

  15. Status of Project-Level Activities • 3. Update Baseline Data Sets • Objective is to improve degree of confidence in projected TP loads in inflows to STAs and the EPA • Update to be completed once every two years • First update completed in FY 2005 as part of EAA Regional Feasibility Study: • Updated 36-year simulation (SFWMM) with latest calibration data for EAA runoff • Updated historic flow and water quality data used to develop monthly flow-weighted mean concentrations • Monthly flow-weighted mean concentrations applied to revised simulated flow data (36 yrs)

  16. Status of Project-Level Activities • 4. Basins with Limited Current Data • Objective is to improve estimates of runoff and TP loads from C-51W, L-28 and C-11W Basins • C-51W basin data analysis completed in FY 2005 • Results indicate this basin’s FWMC is about 38% lower than previously assumed • Results used to update the STA inflow data sets as part of the EAA Regional Feasibility Study

  17. Status of Project-Level Activities • 5. Influence of CERP Projects on Inflow Volumes and Loads • Objective is to revise STA inflow data sets to reflect results of design phase of EAASR Project Phases 1 & 2 • First update completed in FY 2005 using A-1 Reservoir preliminary information • Part of EAA Regional Feasibility Study in FY 2005 • Second update to occur in FY 2010 using results of Phase 2 design

  18. Status of Project-Level Activities • 6. Lake Okeechobee Long-Term Trends • Significant portion of water to be treated in the STAs (in particular STA-3/4) will come from Lake 0keechobee • Objective is to obtain better understanding of temporal and spatial characteristics of water leaving Lake • Water quality and flow from structures discharging from Lake to EAA (S-351, S-352, and S-354) examined in FY 2004 • Analyses continued in FY 2005 • Results expected FY 2006

  19. Status of Project-Level Activities • 7. Adaptive Implementation • Objective is to provide funding for implementation of additional STA enhancements or for integration with CERP projects to enhance water quality performance • Provided FY 2005 funding for EAA Regional Feasibility Study, part of revised Part 2 of Long-Term Plan (Nov. 2004) • Evaluating alternatives to optimize interaction between CERP projects and the ECP STAs • Goal is to optimize phosphorus removal and achieve long-term water quality goals in EPA

  20. Status of Project-Level Activities • 8. Program Management (District staff): • Project management • Development of technical documents • Contract Management • Maintenance of P3e project schedules • STA operational support

  21. Revisions to the Long-Term Plan • LTP predicated on process of adaptive implementation • Revisions shall be approved by FDEP per 2003 amended EFA • Summary of revisions in annual SFER • First request for revision submitted to FDEP on March 18, 2004 • Integration with Bolles & Cross Canal Project • FDEP approved on April 15, 2004

Revisions to the Long-Term Plan • Major revisions to Part 2 of LTP submitted November 2004 • Modification of STA Enhancements • Addition of STAs on Compartments B and C • Addition of the Regional Feasibility Study • Addition of recreational facilities at all STAs • Revisions approved by FDEP December 2004 • Impacts to LTP total projected costs are being evaluated

  23. Remaining Challenges and Uncertainties • Regulatory Issues • Issues with TP Rule Resolved - EPA approved July 2005 • Stormwater Treatment Area Optimization • Some uncertainty remains regarding effectiveness of enhancements • Source control measures • Uncertainty in effectiveness of urban BMPs • Synchronization with CERP projects • Implementation schedules and final designs

  24. Peer Review Comments • Richard Meganck • Will LTP projects result in suite of BMPs to be applied throughout entire project area? • Not all LTP projects will result in BMPs • STA Optimization, Accelerated Recovery • BMP projects may be localized not system-wide • Is there a strategy for coordinating with other agencies in implementation of various LTP projects? • Constant Communication, Public Meetings, Internet postings • Does District experience indicate you can actually determine effect of water quality measures? • LTP includes modeling and research to assist in identification of recovery of impacted areas of EPA

  25. Peer Review Comments • Richard Meganck (cont.) • Text implies that certain restoration activities won’t be implemented until after TP criterion achieved • Water quality improvement projects are being implemented in previously impacted areas. • Intent is to avoid sending discharges to unimpacted areas until discharge concentrations achieve criterion • Any progress with Challenges/Uncertainties? • Progress has been made, see earlier reports with longer lists • Continue reporting to maintain public awareness • How are Baseline Data Sets Validated? • LTP recognized need to continually update the data sets to ensure best available information used throughout implementation of LTP

  26. Peer Review Comments • Neal Armstrong • Plan includes basic elements for success • Water quality management & adaptive management • Chapter could be enhanced considerably • Management process • Overall results to date • Progress in achieving the water quality goals • Response: • Agree. FY 2005 was only 2nd year of implementation; propose enhancing next year’s chapter as recommended

  27. Peer Review Comments • Jeff Jordan • Adaptive Management approach is working • Source Controls are biggest challenge • District could identify and design policies in conjunction with agriculture to improve source controls • Future SFERs should focus on source controls • Response: • See Chapter 3 of SFER for details on District’s existing extensive Source Controls Program

  28. Peer Review Comments • DOI Technical Comments • Currently under review • Will be addressed in Final Report as appropriate
