[BNC-all] Down Time for Semi Annual PM for Cleanroom and Labs, ON BEHALF OF MARK VOORHIS

[Deborah Starewich]

Our schedule for the fall semi annual cleanroom PM is set for September 4
and 5, 2007 starting at 7:30 AM.   The east & west lab PM is set for
September 6, 2007 starting at 7:30 AM.  All cleanroom and labs processes
will be shut down during these times.

During the Cleanroom shut on September 4 & 5 the following systems will be
down affecting the ENTIRE BUILDING, due to no chemical exhaust systems.

- Ultra pure water 
- All toxic gases 
- H2 generator

Both east and west lab wings will down all day on September 6.

Since the chemical exhaust systems will be down, all chemicals are required
to be removed from all fume hoods prior to 4:00 P.M. on the day before the
PM start date (Cleanroom Sep 3 and Labs Sep 5).  Any chemicals left in fume
hoods after this time will be remove prior to shut down.

Thank you for your patients in this manner.
