18. NRRRF ERP Project Lessons Project Background CORPUD and NRRRF had many emergency plans, but no good hands-on plans for plant staff Needed to address emerging threats, such as wastewater influent contamination and active shooters Wanted to do a “grass-roots” project with strong plant staff involvement and minimal consultant assistance 18

19. NRRRF ERP Project Lessons Project Methodology - 1 Formed a team comprised of Emergency Management Team members Led by Division Director, Plant Superintendent, Several Program Managers Hired consultant, with emergency preparedness experience but with a specific scope that included guidance and support 19

20. NRRRF ERP Project Lessons Project Methodology - 2 15 meetings, about 1/2 without the consultant Work products centered around a series of incident-specific response flow charts Small tabletop exercises were used to test the flow charts Influent contamination Tornado Fire On-site chemical release 20

22. NRRRF ERP Project Lessons Lessons Learned - Initial A major commitment is needed to set aside the time for a project like this The involvement of internal staff is critical to get a product that really works for the plant We didn’t realize how deficient we were until we really drilled into it Some up-front work is needed to develop the process and it took a while to hit our stride 22

23. NRRRF ERP Project Lessons Lessons Learned – Flow Charts Flow chart plans are much more challenging than text plans and it took some iterations to get them right Flow charts provide much clearer direction and more valuable detail to the first in-house personnel responding to an incident It’s important not to get too far down in the weeds 23

24. NRRRF ERP Project Lessons Lessons Learned – Other The little tabletop exercises were very helpful in testing the flow chart procedures The work developed provides an excellent framework Plan requires annual review and updating The plan is one tool in the response toolbox and needs to fit in with other CORPUD and City response plans 24

25. NRRRF ERP Project Lessons Current Status and Next Steps Putting on the finishing touches Preparing to develop similar plans at the other PUD Facilities Striving for consistency Constantly changing 25
