7Bacteria 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)
8Bacteria 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)

14Proposed 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
15Positive 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?
16Virginia 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.
17Troubled 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.

22To conclude where are we?
- Infrastructure improvements in the LTCP and CSO
Special Order schedule - Triennial Review comment period (March 31 May

- WLA
- UAA
- Protect COR Investment in CSO Controls to Date
and Ensure Future Costs Result in the Best Water
Quality
