THE CHESAPEAKE BAY TMDL Restoring Waters of the
Rappahannock River Basin and the Chesapeake Bay
  • Rappahannock River Basin Commission
  • December 2, 2009
  • Richmond, Virginia
  • Rich Batiuk
  • Associate Director for Science
  • U.S. EPA Chesapeake Bay Program Office

Low to no dissolved oxygen in the Bay and tidal
rivers every summer

Nutrient Loads by State
Nitrogen
Phosphorus
EPA estimates a nitrogen load of 284 million lbs
nitrogen in 2008. EPA assumes a reduction of 7
million lbs due to the Clean Air Act. This leaves
77 millions lbs to be addressed through the TMDL
process.

Interim Targets
Final Targets
Milestones for Assessing Progress
Stage 1 Implementation
Stage 2 Implementation
  • Also divide jurisdiction load by 303(d) segment
    drainage area and, by November 2011, local area
  • Attain jurisdiction-wide load reductions by the
    interim target, or justify why can still meet
    final target
  • Jurisdiction would determine desired 2-year
    schedule to meet interim and final target loads
  • EPA first evaluates milestones based on
    consistency with jurisdiction target load. EPA
    accepts shifts among source sectors, basins,
    segment drainages, and local areas if
    jurisdiction target load is met and local and Bay
    water quality goals are achieved

12
Federal Consequences
  • Directed at states not achieving expectations
  • Will be outlined in an EPA letter this fall. May
    include
  • Assigning more stringent pollution reductions to
    regulated point sources (e.g., wastewater,
    stormwater, CAFOs)
  • Objecting to state-issued NPDES permits
  • Limiting or prohibiting new or expanded
    discharges (e.g., wastewater, stormwater) of
    nutrients and sediment
  • Withholding, conditioning or reallocating federal
    grant funds

Bay TMDL Bottom-line
  • Actions will clean and protect local waters in
    the Rappahannock basin thereby supporting the
    local economy
  • Restore a thriving Chesapeake Bay
  • Federal, state, local officials and agencies will
    be fully accountable to the public
  • Consequences for inaction, lack of progress
