Whats the Scope of the Bay TMDL?
  • TMDL will establish loads for all Bay states
  • Nutrients, sediments
  • Oxygen, clarity/Bay grasses, algae
  • All impaired tidal water segments
  • All sources
  • Point source control thru NPDES
  • NPS implementation thru 319 funding

8
Not one bay TMDL but (as many as) 92 segment
TMDLs
9
Impaired Segment TMDLs
  • EPA Regulations require TMDLs for each impaired
    Water Quality Limited Segment
  • TMDLSD ? WLASD ? LASD MOS
  • TMDLSD Segment Drainage TMDL
  • WLASD WLA from Segment Drainage
  • LASD LA from Segment Drainage
  • MOS Margin of Safety (implicit)

10
Segment Drainages for Impaired Segment TMDLs
Potomac Tidal Fresh (POTTF)
Potomac Oligohaline (POTOH)
11
Wasteload Allocation
  • For Tidal Fresh Segments
  • WLASD ? individual WLAs (tidal state)
  • Gross WLA (nontidal state)
  • Other Segments
  • WLASD ? individual WLAs (tidal state)
  • Determined by each states Implementation Plan
    development process and could include
  • POTW Industrial Stormwater
  • MS4s Non-significant permits
  • Others?

12
Load Allocation
  • For Tidal Fresh Segments
  • LASD Source Sector LAs (tidal state)
  • Gross LA (nontidal state)
  • Other Segments
  • LASD Source Sector LAs (tidal state)
  • Source Sector LAs would be based on each states
    Implementation Plan development process and could
    include
  • Agriculture Forest
  • Other NPS Urban/Res/Road
  • Atmospheric Others?

13
Bay Cap
  • The Bay Cap will be set for each pollutant (N, P,
    and sediment) to meet water quality standards at
    critical conditions (i.e. worst case scenarios)
    for the entire Bay as well as localized
    impairments.
  • Bay Cap ? Bay Impaired Segment TMDLs
  • ? Bay Unimpaired Segment Loads
  • (i.e., The Bay Cap based on 2003 Allocations
    would be 175 MPY for N and 12.8 MPY for P)

18
Building the Chesapeake Bay Nutrient TMDLs
Determine the Bay cap load
Allocate the Bay cap load to basin-jurisdictions
Establish the TMDL for each impaired segment
Sub-allocate the basin-jurisdiction loads to
sources in state implementation plans
Determine which source loads go into each
impaired segment
19
A TMDL is not enough!
20
Consequences/ Contingencies
21
How does it all fit?
System/Process Question Document
Accounting What loads to achieve? Bay Cap load, J-B cap loads, segment TMDLs
Planning What controls are needed (e.g. BMPs) State Implementation Plans
Implementation What is the program delivery system? 2 year commitments

What we know?
  • We need a bigger, better toolbox to reduce
    nutrients and sediments
  • The tributary strategies level of effort is not
    enough to restore the bay
  • The existing tributary
  • strategies result in higher
  • loadings than previously
  • thought.
  • -new hydrology
  • -new BMP efficiencies

24
What we need to knowbut dont know yet
  • Sediment allocation process
  • How much will it cost?
  • What are the best enhancements to the existing
    nutrient and sediment control toolbox?
  • Who pays?

25
Building a bigger toolbox
  • Sources
  • Agriculture
  • Air
  • Developed and developing lands
  • Wastewater
  • Tools
  • Public funding
  • Cap and trade
  • Tax incentives
  • Marketing program
  • Corporate Stewardship
  • Regulation
  • Other?

26
Upcoming Deliverables from EPA
  • Reasonable Assurance and Implementation Guidance
  • Staged Implementation
  • Consequences if Milestones are not met
  • Bay TMDL 101 public meetings
  • Preliminary Draft Bay Cap and Basin-Jurisdiction
    Allocations

27
Bay TMDL Outreach
  • Bay TMDL 101 public meetings (Summer 2009)
  • Meetings with Stakeholders and Local Governments
    (ongoing)
  • A River Runs To It (Summer 2009)
  • Visits throughout watershed to highlight best
    practices and present funds for projects
  • EPA Bay TMDL Website (coming soon)

28
Whats on the road ahead?
  • State Implementation Plan Development (May 2009
    May 2010)
  • TMDL 101 public meetings (June Sept. 2009)
  • Preliminary Draft Bay Cap Basin-Jurisdiction
    Allocations (July/Aug. 2009)
  • Draft TMDL Public Notice/Public Meetings (June
    Sept. 2010)
  • Final TMDL Established (December 2010)
  • Consent Decree deadline (May 1, 2011)

29
Coming Attractions
  • Preliminary Draft Chesapeake Bay Cap

Executive Council MeetingMay 12, 2009
  • Announce 2-year milestones
  • Set Restoration End Date
  • Executive Order

31
Milestones Guidelines
  • Will focus strictly on Bay water quality
    restoration goal
  • Jurisdiction-specific milestone outcomes can be
    rolled up into a single, basin-wide summary
  • Milestone outcomes include pounds reduced, acres
    implemented, adoption of new regulations,
    legislation, policies
  • Account for implementation actions of all partners

32
Milestone Attributes
  • First 2-year milestones will be from mid-2009
    through end of 2011
  • Confirming we intend to develop milestones which
    are stretch goals but still attainable
  • Accelerates past rates of implementation
  • Milestones could include commitments to seek new
    regulations, enactment of new legislation/policies
  • Translate or relate actions and resources to Bay
    water quality endpoints
  • Measurable, trackable, reportable and related to
    the end goal (cap load allocations)
  • Consistency across the 7 jurisdictions

  • Nitrogen
  • Additional 6.9 million pounds nitrogen reduced
  • 77 increase over previous rate of reduction
  • Phosphorus
  • Additional 463,948 pounds phosphorus reduced
  • 79 increase over previous rate of reduction

36
A New Restoration End Date
  • The date by which all the actions required to
    achieve the jurisdiction-specific and basinwide
    cap load allocations have been fully implemented
    on the ground

  • Provides hundreds of millions of dollars for
    projects that advance the cleanup of the
    Chesapeake Bay
  • Projects range from WWTP upgrades to green
    infrastructure projects
  • Farm Bill
  • Additional 188 million over next four years for
    agricultural conservation projects to reduce
    pollution flowing into the Bay
  • Support nutrient management, cover crops, crop
    residue management, vegetative buffers, and other
    agricultural conservation practices

39
Accountability

EPAs Draft Bay TMDL Framework
  • States existing Chesapeake Bay WQS should not be
    relaxed based on feasibility
  • Bay TMDLs must contain the LAs and WLAs necessary
    to achieve the states existing Chesapeake Bay
    WQS
  • State Implementation Plans will be written to
    achieve the loadings assigned in the Bay TMDLs
  • Staged implementation is a possible option
  • Wastewater discharge load requirements will
    continue to be set at the discretion of states
  • An affordability assessment will be completed
