November 3, 2003 – Consideration of ABM support for FDEP Extension Request


PRIMARY OBJECTIVE Piney Point Closure

  • Reduce Inventory of Process Water and Initiate Closure Activities

  • Long Term Water Management Plan (WMP)

  • Closure Plan – Dewater, Line, Isolate, and Close Pond Storage Compartments


  • Site has Received Excessive Rainfall during the last 12 months

  • Average Rainfall Adds 160 MGal to the Site each year

  • Closure Activities Delayed

  • 2004 Dry Season Closure Plan – Close one stack compartment and prepare to close two additional compartments

MEETING WMP OBJECTIVE


WATER MANAGEMENT CHALLENGE the last 12 months

  • 600 MGal Ponded Process Water

  • 600 MGal Pore Water

  • Increase Storage so that Significant Closure Work can be Accomplished Prior to the 2004 Rainy Season

  • Must Discharge “Double-Lime” Treated Water


AMENDED WMP the last 12 months

  • Water Balance Model Recalibrated

  • Increase Target Wastewater Removal Rates (2 MGD to Over 4 MGD)

  • Time Period – Minimum 3 to 5 Months

  • Increase Storage so that Significant Closure Work can be Initiated


EMERGENCY ORDER the last 12 monthsFIFTH MODIFICATION SEPTEMBER 5, 2003

  • Double Amount of Water Removed From 2 MGD to 4 MGD

  • Increase Amount of Reverse Osmosis Water 0.6 MGD to a Minimum of 1.0 MGD (By 10/15/2003)

  • Increase Amount of Double-lime Aeration Water Minimum of 3.0 MGD (By 10/15/2003)

  • Resumption of Double-lime Aeration Water to Bishop Harbor

  • Target Ammonia Nitrogen Loading Rates (WQ Modeling Report)

    • 308 Pounds Per Day (15 Day Rolling Average)

    • 600 Pounds Per Day (Maximum)


Potential Bishop Harbor Load the last 12 months

Overall Tampa Bay Load Reduction Target

N Load (pounds per day)

LTB Load Reduction Target


REASONS TO SUPPORT EXTENSION REQUEST the last 12 months

  • Risk of a Catastrophic Accident Remains until Site is Permanently Closed

  • Immediate need to Reduce Water On-Site to Initiate Closure Activities

  • RO is not the only Solution

  • “Double – Lime” Treated Water must be Discharged somewhere


REASONS TO SUPPORT EXTENSION REQUEST the last 12 months

  • Only Current High-Volume Alternative to Discharge to Bishop Harbor is Gulf Dispersion

  • Extension will Reduce Discharges and Nitrogen Loading to Bishop Harbor

  • Extending the Permit Removes an Additional 70 to 75 MGal per month from the Site

  • Additional Water off-site improves Water Balance, Dam Safety and Minimizes the Risk of Accidental Discharges


REASONS TO SUPPORT EXTENSION REQUEST the last 12 months

  • FDEP has met Current Conditions of Emergency Permit

  • No Adverse Environmental Impacts to Marine Water Quality or Marine Life

  • Continued Ocean Dispersal should be Part of a Multi-Faceted Treated Wastewater Reduction Plan


BOTTOM LINE the last 12 months

  • SHARE THE LOAD…

  • USE OTHER HIGH VOLUME ALTERNATIVES AS LONG AS POSSIBLE…

  • MINIMIZE THE LOAD TO BISHOP HARBOR AND TAMPA BAY !!!!
