    1 15 Tmdl Chesapeake Bay 1 15 Tmdl Chesapeake Bay Presentation Transcript

    • Chesapeake Bay Term: TMDL
    • TMDL
      • Total Maximum Daily Load
      • Will set limits for nitrogen, phosphorus, and sediment
      • TMDL is a calculation of the maximum amount of a pollutant that a waterbody can receive and still safely meet water quality standards
    • Section 303
      • A section of the Clean Water Act that requires states to list impaired waters
      • Fauquier County Impaired Waters
      • Cedar Run – E. Coli
      • Great Run – E. Coli
    • Chesapeake Bay Watershed
      • Water Quality in this area will be controlled by the EPA
    • Timeline
      • Bay cleanup goals from 1987 and 2000 were missed by wide margins
      • June 2008 – Virginia and the Chesapeake Bay asked for Federal help in clean-up
      • May 2009 – President Obama signed an Executive Order
        • Gives EPA control over local jurisdictions
    • Timeline
      • Executive Order is published May 12, 2009
      • EPA accepted comments & input through Dec 18, 2009
      • EPA has until June 2010 to publish a draft TMDL
      • There will be a comment period from June to September
      • Final TMDL is due by December 2010
      • First goals will be met by December 31, 2011
      • 60% of nutrient reduction goal by 2017
      • Clean Bay by 2025
    • Monitoring
      • Bay area is divided into 92 Segments
      • Parts of the Upper Rappahannock & Middle Potomac fall in Fauquier County
      • Milestones must be met every two years
    • Paying for Clean-up
      • Most costs fall on state and local governments – most have budget deficits
      • States must submit plans to clean-up by June 1 st .
      • Costs are estimated at over $15 Billion
    • What are the consequences?
      • If voluntary or contract conservation methods do not work, states will have to pass and enforce laws to decrease nutrient loads.
        • Will make some types of fertilizers only available by permit
        • Will restrict permits for building/developing
        • Will restrict Confinement Animal Feeding Operations (CAFOs)
    • Enforcement
      • National Pollutant Discharge Elimination System (NPDES) permits – waste water
        • Easier to regulate – EPA will take over permitting
        • Will affect CAFOs esp. pork & poultry
      • Non-point Source Pollution
        • Hard to regulate
        • Enforcement is Unknown
      • Transparent Monitoring – Nutrient numbers will be available to the public
