9/9 FRI 11:00 | EPA's Numeric Nutrient Criteria 1


Published on

Kevin Carter

The Environmental Protection Agency (EPA) has announced its intent to adopt numeric nutrient criteria for Florida’s water bodies (lakes, streams, canals and estuaries). The criterion is
unprecedented in the nation and has drawn national attention to Florida’s water quality programs. The panel will discuss the
legal genesis of this proposed rule, including the most up to date developments in the state legislature and Congress; its technical
aspects, including the scientific basis for the rule; implementation and relief mechanisms; and the criteria’s impact on Florida’s current permitting programs, as well as its impact on a wide variety of stakeholders in Florida.

  • The national nutrient strategy describes the approach we will follow in developing nutrient information and working with states and tribes to adopt nutrient criteria as part of their water quality standards. The strategy presents overenrichment assessment tools and recognizes current capabilities for conducting these assessments at the regional watershed and waterbody levels. The major focus of this strategy is the development of waterbody-type technical guidance and region-specific nutrient criteria . Once waterbody-type guidance and nutrient criteria are established, we will assist states and tribes in adopting numerical nutrient criteria into water quality standards 01/09/2011 K.Carter, SFWMD, Numeric Nutrient Criteria in Florida
  • Variability in the type, amount, and quality of data used for the rulemaking can be challenging 01/09/2011 K.Carter, SFWMD, Numeric Nutrient Criteria in Florida

    4. 5. NNC: An Abbreviated History (cont.) <ul><li>2001 State of Florida (FDEP) begins collaborative process with EPA to develop NNC </li></ul><ul><li>2003 FDEP forms Technical Advisory Committee ( governed by Florida’s Sunshine Laws ) </li></ul><ul><li>2003-2009: TAC focused on freshwaters: lakes, rivers and streams, springs and canals </li></ul>
    5. 6. <ul><li>Many challenges in developing this criteria (not limited to the following): </li></ul><ul><ul><li>Nutrients are necessary for fish and wildlife to exist and thrive in aquatic systems </li></ul></ul><ul><ul><li>What are the appropriate response variables? </li></ul></ul><ul><ul><li>Aquatic system diversity is quite large and expands across a large geographic area </li></ul></ul><ul><ul><li>Variability of aquatic systems can be high through time and over large spaces on many different scales (e.g., days to years) </li></ul></ul>The TAC’s challenges
