  1. Senate Bill 3Environmental Flows Panel Dan Opdyke Danny Vance Jack Tatum Bob Huston

  2. Dan Opdyke Texas Parks and Wildlife Department TWCA Mid-Year Conference June 19, 2009 SB 3 Article 1 Overview

  3. Water Rights Permitting Current Situation Environmental flow requirements applied to large water rights applications identified on a case by case basis Project-specific public participation Desired Future Situation Proactively identified and consistently applied flow requirements so applicants have more certainty Regional stakeholder and scientific participation

  4. Purpose of SB 3 Article 1 • Establish Environmental Flow Recommendations • 11.0235(d-6): • The legislature finds that recommendations for state action to protect instream flows and freshwater inflows should be developed through aconsensus-based, regional approach involving balanced representation of stakeholders and that such a process should be encouraged throughout the state.

  5. Purpose Continued Environmental Flow Regime: 11.002(16): A schedule of flow quantities that reflects seasonal and yearly fluctuations that typically would vary geographically, by specific location in a watershed, and that are shown to be adequate to support asound ecological environment and to maintain the productivity, extent, and persistence of key aquatic habitats in and along the affected water bodies.

  6. Existing State and Regional Groups Environmental Flows Advisory Group (EFAG) Senator AverittRepresentative Hamilton,Co-presiding Officers Basin and Bay Area Stakeholder Committees (BBASC) Jerry Clark, Sabine/Neches Chair Danny Vance, Trinity/SJ Chair Science Advisory Committee (SAC) Bob Huston, Chair TCEQ, TWDB, TPWD input as appropriate Basin and Bay Area Expert Science Teams (BBEST) Jack Tatum, Sabine/Neches Chair Bill Espey, Trinity/SJ Chair Public Input TCEQ Rule Making

  7. Primary Roles Environmental Flows Advisory Group (EFAG) ∙ Provide Oversight, Review and Make Recommendations, and Report to State Leadership TCEQ, TWDB, TPWD input as appropriate Science Advisory Committee (SAC)∙ Provide Science-based Direction, Coordination, and Consistency Basin and Bay Area Stakeholder Committees (BBASC)∙ Consider Human Water Needs and Recommend Environmental Flow Standards and Strategies Basin and Bay Area Expert Science Teams (BBEST) ∙Develop Science-based Environmental Flow Analysis and Recommend Environmental Flow Regime (without regard to other needs) Public Input TCEQ Rule Making∙ Establish Flow Standards and Set-asides

  8. Set-Asides and Alternatives 11.1471(a)(2)Establish an amount of unappropriated water, if available, to be set aside to satisfy the environmental flow standards to the maximum extent reasonable when considering human water needs 11.0235(d-3)(2)In those basins in which the unappropriated water that will be set aside for instream flow and freshwater inflow protection is not sufficient to fully satisfy the environmental flow standards established by the commission, a variety of market approaches, both public and private, for filling the gap must be explored and pursued.

  9. Current Timeline 11/1/2009 – Existing BBESTs submit recommendations to BBASCs 5/1/2010 – Existing BBASCs and EFAG submit comments to TCEQ 5/1/2011 – TCEQ adopts flow standards Colorado/Lavaca and Guadalupe/San Antonio:10 month lag (except BBASCs have not been named…nominations being accepted now) Nueces, Rio Grande, Brazos:22 months lag --Schedule subject to modification by EFAG--

  21. Relationship between Stakeholders Committee and Expert Science Team • The Expert Science Team is charged with developing an environmental flow regime based upon the best available science without regard to non-environmental uses by Nov 1, 2009. • The Stakeholders Committee is charged with reviewing the recommended regime and considering factors other than strictly environmental needs by May 1, 2010.

  22. Relationship between Stakeholders Committee and Expert Science Team (cont.) • Make recommendations on environmental flow standards and strategies to TCEQ and the Environmental Flows Advisory Group
