Water Quality Coordination / TMDL Allocation for
the James River Virginia

Bacteria TMDL Development, Watershed Planning and
Water Quality Standards Coordination
  • UAA
  • Data Collection (fill data gaps, review
    translator)
  • Watershed Model Development (DEQ assumptions, CSO
    watershed model input, review DEQ contractor
    calibration)
  • Watershed Modeling (scenarios and results)

8
Bacteria TMDL Development, Watershed Planning and
Water Quality Standards Coordination
  • TMDL Review (WLA, TMDL result and implementation
    plan, LTCP)
  • WQS Triennial Review (bacteria standard, CSO
    policy and COR CSO Special Order)
  • Water Quality Standards Coordination (How will
    the COR be able to measure the LTCP outcome is
    compliant?, Phase II CSO Permit Requirements)
  • Watershed Approach (watershed sources, trading
    scenarios and implementation options for cost
    effective water quality compliance)

Proposed 9 VAC 25-260-170. Bacteria
Recreational Waters (Primary)
  • Geometric means shall be calculated using all
    data collected during any calendar month with a
    minimum of four weekly samples
  • For beach advisories or closures, a single sample
    maximum of 235 E. Coli CFU/100 ml freshwater and
    a single sample maximum of 104 enterococci
    CFU/100 ml in saltwater and transition zones
    shall apply

15
Positive Benefits for both Assessment and TMDL
Programs
  • more reasonable and cost-effective management
    plans to attain the water quality standards.
  • more reasonable primary recreation criteria
    there would be less incentive for pursuing
    secondary contact designation in waters.
  • Special standards to implement LTCPs in the
    Commonwealth?

16
Virginia Dept of Health Concerns
  • Inquire from DEQ Director and Secretary of
    Natural Resources for their position on one
    particular issue.
  • Should the bacteria criteria for freshwater in VA
    Water Quality Standards be revised based on an
    illness rate of 1, which would be an increase
    from the existing 0.8 rate?
  • Protective of primary contact recreation and
    would be acceptable to EPA.
  • Reasonable given the marine illness rate is
    almost twice the freshwater illness rate.

17
Troubled waters
  • concern is that could be perceived by the
    public as a step in the wrong direction for water
    quality protection.
  • Risk levels and illness rates can elicit
    reactions that are based on emotion and not fact
    and do not weigh the positive aspects of such a
    change.

To conclude where are we?
  • Infrastructure improvements in the LTCP and CSO
    Special Order schedule
  • Triennial Review comment period (March 31 May
    30 2008)
  • TMDL development and implementation
  • WLA
  • UAA
  • Protect COR Investment in CSO Controls to Date
    and Ensure Future Costs Result in the Best Water
    Quality
