Integrated Reporting• Exceeding Criteria ‐‐Category 4 or 5 (Impaired) • 1,500 in draft 2016 IR
Poor or Fair benthos or fish community ratingsGreater than 10% of samples exceeding a numeric standard
• Meeting Criteria– Category 1• 14,500 in draft 2016 IR
Good or Excellent benthos or fish community ratingsLess than 10% of samples exceeding a numeric standard
• Data Inconclusive—Category 3• 2,000 in draft 2016 IR
Not Rated benthos or fish community ratingsLess than 90% confidence in 10% exceedances

Category 4 vs. Category 5
•Both assessment Categories Exceeding Criteria
•No difference Water Resource Condition
•Category 5 requires a “PLAN” per CWA• TMDL• Management Plan
•Category 4 • “PLAN” completed/not required‐ but Water Resource Condition has not yet changed

DEQ DWR Commitment
•Develop Restoration or Protection Plans for 58 waters• Scheduled through 2022•Protection Plans associated with State Parks• Some TMDLs‐ associated with permitted facilities
•Priority Plans

4t TMDLS• Sets a pollutant reduction target• Parameter specific ‐20% reduction in turbidity needed
• Requires EPA approval to move from Category 5 (303d waters)
• 322 TMDL assessments (AUs with a TMDL for at least one parameter)
• 92 are in Category 1t (most without documented implementation)
• TMDLs more appropriate for permitting
• Most Category 5 Assessments are not related to permits

Alternatives to TMDL Development
•4b Management Strategy
•5r Priority Plan or 9‐element plan
•4c Hydrologic Alteration Dam (if time)

4b Demonstrations• Plan to implement a Pollution Control Strategy
• Requires EPA approval to move from Category 5 (303d waters)
• Requires robust schedule of implementation (rules and money)
• Regular updates to EPA (track implementation success)
• There are 22 AUs under 4b demonstrations
• Examples in NC include• Falls Lake Nutrient Management Strategy
• Little Alamance Creek‐ Burlington
• McDowell Creek‐ Charlotte
• Ore Knob‐ EPA superfund

5r (5‐alt)Demonstration‐ New
•Priority Plan, Watershed Restoration Plan or 9‐Element Plan
•Priority Plans do not have $$ and Rules•Required for 319 and other funding sources•Delays TMDL development• EPA does not approve the Priority Plan –still in Category 5
• EPA does determine if the Plan will count toward DWR commitment

Water Resource Planner
•Rapid development and update of watershed plans
•Web map based information
• Integrates information from existing tools and new tools into the watershed plan
• Improve stakeholder education and communication
• Improve project tracking and improvements
•Measures UPLIFT at project level temporal and spatial scales

4c Demonstrations (New‐ Kind of)• Current NC use of Category 4c
• Exceeding Criteria and a dam or hydrologic alteration is the proximal reason for Exceeding Criteria
• Requires EPA approval when moving from Category 5
• Currently NC has 12 4c assessments
• EPA guidance is encouraging greater use of 4c to identify waters where hydrologic alteration is a concern
• NC is working through the an assessment method that may be used by 2018
