  2. Bay TMDL Schedule 2010 • December 31 – EPA Issued final Bay TMDLs in Federal Register 2011 • November 1 – States/DC submitted draft Phase II WIPs • December 31 – Bay States completed first set of 2-Year Milestones (2010-2011) 2012 • January - States/District submitted final 2012-2013 milestones to EPA • March 30 - States/District submitted final Phase II WIPs to EPA 2017 • Mid-Course Assessment -- EPA to assess implementation progress (60% of full WIP implementation to be achieved by this date) • States to submit Phase III WIPs to EPA: draft by June 1, final by November 1 (dates in flux) • EPA to determine whether to revise TMDL allocations 2025 • 100% of WIP implementation to be achieved Bay-wide WRTC Meeting (11/8/12)

  3. Mid-Course Assessment Guiding Principles • Keep the focus on implementation and maintain stable tracking and reporting through 2017 (parallel tracks) • Enhance decision support and assessment tools to enable successful engagement of local partners • Incorporate verification of practices into existing accountability tools and reporting protocols • Address emerging issues that may impact current strategies and future plans • Prioritize midpoint assessment actions and adaptive management to ensure Phase III WIPs meet water quality goals WRTC Meeting 11/8/12

  4. Water Quality GIT Meeting Oct. 22-23 What Was Discussed • What changes should be made in TMDL toolbox (primarily models) • Set priorities for CBP workgroups and CBP staff • Set schedule for producing Phase III WIPs • 2017 (or maybe 2018) – need to work backward from this data; allow adequate time for review, model calibration, etc. WRTC Meeting (11/8/12)

  5. Water Quality GIT Meeting Oct. 22-23 What Wasn’t Discussed • Changes to allocation methodology • Change in schedule • Need for use attainability analysis WRTC Meeting (11/8/12)

  7. Shift to simpler loading model WRTC Meeting (11/8/12)

  8. Make MAST/CAST/VAST the accounting tool forTMDL WRTC Meeting (11/8/12)

  9. Next Steps • MAST/CAST/VAST regional library • Tap into local land use data • Explore data behind regionalization factors • Look at our own Chain Bridge monitoring data as check on Bay Program modelling data WRTC Meeting 11/8/12
