2.       Review the Credible Single Contingency assignment from ROS for completion.

3.       ERCOT has submitted NPRRs 528 and 529 to move their internal procedures for RAPs, PCAPs, TOAPs and MPs into the Protocols.   At its meeting last week, ROS asked OWG to consider the NPRRs and provide comments to ROS at either their May or June meeting.   Friday, WMS assigned them to CMWG with a request for them to return their comments to WMS in May. 

• Proposed: we would like the official comment from OWG to go to ROS in June to give us more time to get comments from OWG members.
