3. 7a: Revision of Previous Plan Draft HAB Response and Communication Plan presented to Technical Committee June 2015 Goals and Introduction Algae/Toxin Standards HAB Determination and Monitoring Communication/Contacts Resources Original goal was to incorporate comments and re-submit in October 2015 Superseded by HAB event New plan is to revise in context of larger HAB problems and have a draft for June 2016 Tech meeting

4. Goals and Introduction Goals: Allow the States and local health departments to manage the Ohio River as a source of recreation Allow water utilities to use the Ohio River as a source of safe drinking water No proposed changes to the goal statement Introduction Provides general information regarding HABs and algae on the Ohio River Introduction will be revised to reflect new understanding of HABs on the Ohio River.

5. Algae/Toxin Standards Identifies Standards published by States, USEPA, WHO Reference revised State standards Contact Recreation standard expected from USEPA in 2016. This will be referenced when it is proposed. We will not “adopt” a standard Ohio EPA Finished Drinking Water Advisories for Algal Toxins Threshold (ug/L)MicrocystinAnatoxin a Cylindrospermops in Saxitoxin Drinking Water- Do Not Drink 12010.2 Drinking Water- Do Not Use 20300203

6. HAB Determination and Monitoring Sampling SOP Recommended analyte list Sample site selection Surface, near surface or intake depth Near shore, mid channel or “representative” Intake structures, access points, heavy growth areas, periodic Identification of sampling goals Initial identification, define extent, protect designated uses

7. HAB Determination and Monitoring When does the bloom end? WV-1 set of clean samples from the affected area OH-2 weeks of clean samples from affected area KY-2 weeks of clean samples from every location that had a hot sample These decisions will be determined in coordination with the involved agencies SituationActions Conditions are suitable for an algae bloom Communications: ORSANCO will inform the Ohio River water utilities of the conditions. Actions: Continue to monitor Potential algae bloom reported Communications: If a potential algae bloom is reported, ORSANCO will coordinate with the affected States for confirmation samples. Ohio River water utilities will be informed Actions: If the reporting entity is a water utility ORSANCO will provide sampling materials. If the reporting party is not a water utility ORSANCO will collect water samples for confirmation of algae concentration. A toxin test strip will be used as a presence/absence test.

8. Communications Needs Coordination of sampling crews Identification of laboratories Need for advisories Press releases Data dissemination Primary contact is identified. More can be added as required.

10. References Update to recognize new information Development of ORSANCO HAB web page

11. Revision to Previous Plan Final draft presented at June 2016 Technical Committee meeting And there was never a HAB on the Ohio River ever again. And they lived happily ever after. The End

12. 7b: Data Assessment Strategy Goal: Develop an understanding of the causes of the 2015 HAB event and their implications for the future of HABs on the Ohio River.

13. Identification of Potential Stressors Precipitation Flow Water clarity Nutrient concentration, ratios and timing Temperature Other water quality factors Alkalinity Conductivity Herbicides Zebra mussels

14. Collect Available Data Internal routine monitoring (Bi-Monthly Program) Internal event monitoring Water utility data (requested) State data (requested) NWS/USGS gauge data Historical satellite imagery Provide data to other interested researchers (ORD)

15. Data Assessment Was 2015 fundamentally different than other years? Conditions prior to bloom Conditions at time of bloom Comparison to areas which did not have the bloom (both upstream and downstream) Are there clear causes identifiable

16. Recommendations for Future Sampling Identify data gaps Recommend future sampling to fill the gaps

17. Report Draft report distributed to Technical Committee for review
