Update on chesapeake bay program developments

Briefing to the

Water Resources Technical Committee

January 8, 2009

Update on Chesapeake Bay Program Developments


Water quality steering committee

Water Quality Steering Committee

  • Bay TMDL Development

    • Still on schedule overall (minor delays for some)

      • Draft major basin/state load allocations – April 2009

      • Bay TMDL – Dec. 31, 2010

    • 78 TMDLs (i.e., by river segments/Designated Uses)

    • Current Tributary Strategies not sufficient to achieve DO standard

    • UAA Process

  • Next WQSC Discussion – Jan. 12th

WRTC Meeting (1/9/09)


Key issues activities

Key Issues/Activities

  • Subdividing Allocations - Local Allocations

    • MS4 Stormwater Permits

      • How to Allocate in light of anticipated population growth?

    • 2010 Population Projections

      • Compare versus 2003 cap load allocations

    • Drinking Water Treatment Plants

      • Evaluate withdrawals/discharges & implications

    • Define ‘Maximum Feasible’ Scenario

      • Define MS4 assumptions

      • V/MAMWA Letter re: WWTP Model Load Assumptions (i.e., ‘regulatory stability’)

      • Define for Other Sectors?

WRTC Meeting (1/9/09)


Key issues activities1

Key Issues/Activities

  • Use Attainability Analysis (UAA)

    • “Game Plan” – Still to be defined

    • Schedule – To be integrated into TMDL schedule

    • Work Group – Uncertain re: membership & process (i.e., vs. previous effort)

    • Implications – Uncertainty now

      • Will it just affect additional ~20% increase in additional load reductions required?

      • Ability to address broader ‘feasibility’ issues?

    • Cost – Only 1 element of UAA

WRTC Meeting (1/9/09)


Key issues activities2

Key Issues/Activities

  • TMDL Communication/Outreach

    • EPA & State Plans

      • Local Role - Audience

      • COG Region Needs?

    • Relationship to Existing Tributary Strategies

      • Update or TMDL Implementation Plans?

      • Revisit Maximum Feasible?

      • Ability to Address Funding Availability?

WRTC Meeting (1/9/09)


Policy issues questions 1

Policy Issues/Questions - #1

  • Pressure for More Regulatory Requirements

    • WWTPs

      • Limit of technology permit limits

      • Loads capped

    • Stormwater

      • Additional MS4 permits requirements

      • TMDL wasteload allocations reflected in permits

      • Local governments required to develop TMDL implementation plans

      • Calls for stringent land use and development requirements

WRTC Meeting (1/9/09)


Policy issues questions 2

Policy Issues/Questions - #2

  • Funding for Implementation

    • Water and Wastewater Infrastructure

      • Vital role in protecting public health

      • WWTPs - Biggest success in Bay cleanup

      • Systems are aging and in need of attention

    • Stormwater Management Infrastructure

      • Targeted as the biggest issue facing the Bay

      • Virtually no state or federal funding

      • Costs rival those of traditional water and wastewater infrastructure

  • How to prioritize given limited $ resources?

  • How to prioritize given other infrastructure needs?

  • How will Bay cleanup be ‘accelerated’ given competing priorities & limited $ resources?

WRTC Meeting (1/9/09)


Policy issues questions 3

Policy Issues/Questions - #3

  • Bay TMDL Waste Load Allocations - ‘Local’ Allocations

    • What will the scale be?

    • What will the scope of/elements be included in the WLA? (i.e., non-MS4, air, WWTPs, etc.)

    • Will there be source tracking (similar to bacteria TMDLs)?

    • How/will local governments have a say in how the TMDL allocations are developed?

    • How to maximize flexibility for local governments to manage their own growth/load allocations?

WRTC Meeting (1/9/09)


Proposed actions wrtc recommendations to cbpc

Proposed Actions – WRTC Recommendations to CBPC

  • Track/Report/Shape CBP’s WQSC, etc. on behalf of COG members.

  • Plan WRTC Work Session (3/12/09 WRTC meeting/other) for EPA/States to present proposed approaches for “Local Allocations.”

  • WRTC Volunteers - Work with COG staff on recommendations for WRTC/CBPC (& possibly COG Board) on following:

    • Revise 4 COG “Policy Principles” (e.g. given that CBP continues to become increasingly regulatory);

    • Input to CBP re: local wasteload allocations (i.e., scope, elements, WWTP and MS4 stormwater issues);

    • Input to CBP Partners re: 2-year milestones (e.g., EC to adopt in May 2009);

    • Input to States re: local allocations & revised Tributary Strategies &/or TMDL Implementation Plans;

    • Input to States re: implementation policies for urban mgmt. strategies (i.e., funding, cost-effectiveness, permitting, flexibility); and

    • Input to CBP re: UAA process/assumptions.

WRTC Meeting (1/9/09)


Next steps

Next Steps

  • WRTC to endorse recommendations

  • CBPC receives a briefing on January 16th

  • Need WRTC volunteers to help frame issues and develop recommended COG actions.

    • Wastewater

    • Stormwater

    • Local governments

    • Utilities
