  4. 4. Lake Okeechobee BMP Performance •In 1987, the PLRG developed for Lake Okeechobee mandated a 40% reduction in total phosphorus loads to Lake Okeechobee from 531 Mtons to 360 Mtons. The PLRG was to be achieved by 1992. •Following nearly $160 million in direct costs and lost income resulting from BMPs and other programs, the programs implemented failed to meet the 1992 360 Mton SWIM PLRG objective Table 1: Total P Loads (in Mtons) to Lake Okeechobee 1991-20031 Long-term Load Long-term Over-target Year Measured Load a (5-yr moving Load (5-yr moving average) a average) ab 1991 445 415 275 1992 388 393 253 1993 296 375 235 1994 580 421 281 1995 683 478 338 1996 200 430 290 1997 470 446 306 1998 780 543 403 1999 670 561 421 2000c 169 458 318 2001 607 539 399 2002 543 554 414 2003 187d - - Includes an atmospheric load of 35 Mtons per year based on the Lake Okeechobee TMDL (FDEP 2001) bTarget is the AI Lake Okeechobee TMDL of 140 Mtons (FDEP 2001) compared to a five-year moving average c.

  20. 20. ATS™ and Treatment Wetland (STA) Water Treatment Costs University of Florida - IFAS Sano, D., A.W. Hodges and R. L. Degner. 2005. Economic Analysis of Water Treatment for Phosphorus Removal in Florida: Comparison of Wetland Stormwater Treatment Areas and Managed Aquatic Plant Systems. MAPS phosphorus treatment costs ($/kg P-removed) for proposed treatment systems in the Lake Okeechobee Watershed were 53 – 69% lower than costs for wetland stormwater treatment areas. Costs included capital, operations and management, water storage and recreational benefits.
  21. 21. Vision to Optimize Effectiveness Regional Treatment Systems Direct Recovery of Nutrients
  22. 22. Regional Treatment Systems Williamsburg, VA • The city constructs regional stormwater management facilities that generate phosphorus credits by reducing loads beyond existing conditions. • Developers have the the option of meeting their phosphorus removal requirements through the purchase of phosphorus credits from a regional stormwater management facility • The number of estimated pounds of phosphorus removed by a facility is the number of credits it generates. • All of the credits are sold and cover the construction, operation, and maintenance costs of the regional control structure. • Regional system creates a balance between point- and nonpoint- source projects.

  24. 24. Direct Pollutant Recovery and Lake Restoration System as a Cost Effective Option to Meet TMDL Regulations I. Eliminate ancillary water storage costs II. Reduced nutrient recovery costs III. Recover historical pollutant loads IV. Pollutant trading options V. Performance quantifiable
  25. 25. I. Eliminate Ancillary Water Storage Costs • Need for new watershed storage infrastructure eliminated • Eliminated water storage costs can be applied to reduce in-lake pollutants beyond TMDL requirements
  26. 26. II. Reduced Nutrient Recovery Costs • Ancillary water storage system costs eliminated • Pollutant treatment costs lower for systems designed to operate under relatively stable conditions – eliminates peak hydraulic loads associated with storm events • Consistent flows allow smaller facilities (lower costs) to provide equivalent pollutant reduction
  27. 27. III. Recover Historical Pollutant Loads • Eliminated water storage costs to be applied to reduce in-lake pollutants beyond TMDL requirements • Net reduction of in-lake pollutants to improve lake water quality, reducing internally generated pollutant loads (phytoplankton sediment load) • Accrued reduction of in-lake pollutants will eliminating short term impacts of seasonal pollutant loads • Faster restoration of impaired surface water
  28. 28. IV. Pollutant Trading Options • Pollutants recovered by centralized facility • Fees to be charged to individual sources required to reduced pollutant loads (point source and nonpoint source) • Standardized formal agreements and pollutant treatment costs for watershed sources • Eliminates uncertainty associated with nonpoint source management
  29. 29. V. Performance Quantifiable • Pollutants recovered by centralized facility easily quantified • Regulatory monitoring costs reduced

  33. 33. Phosphorus Balance Nearly all of the nutrient pollutants removed within a MAPS are accounted for within the harvested biomass (65-85%) or sloughed biomass (15-35%), which is manifested as organic sediment. As with treatment wetlands, a sediment management plan is required for long term operations. The phosphorus balance for the S-154 Prototype in Okeechobee is shown here. 14.14% 0.71% 35.15% Hyacinth Harvest Gain in hyacinth standing crop 26.72% Algae Harvest Rake 2.40% 11.19% 3.01% Algae Harvest microscreen 0.00% Gain in algae standing crop 6.69% Ecological losses Sedimentation Loss in water column Effluent Discharge
