Safety E. Chang:   We have finished with inspections.   We expect to hold a third machine shop training session.   The task force to determine the failure has discovered the cause to be an undersized aluminum piece.

Regarding ANL sexual harassment training Users have asked if it is required to do work in the ring.   Elroy did not know, but will look into whether or not it is considered a user requirement.

Emergency Access APS recommends users to make requests 48 hours before date of access.  

Beamline Stats Y. Amer:  Yeldez continues work on the stats that are due by end of week to DOE.
