What’s Happening Now - DSS – ICM Response Plan Example

10

What’s Happening Now –

– Established Weekly Operational Review Meetings

– Over 400 Response Plans Since April– Early May – Set to System Automation

Approval – Operational Corridor Threshold Initiated

18% then to 8% (May 21st) – Released 511 – ICM App (May 9th)
