Wet Benches/Develop Tracks Down

Hi everyone --

We're sorry to report that the acid wet benches and developer 
tracks/benches remain down for the time being.  There was a power glitch 
last night which caused the Acid Waste Neutralization system to dump all 
its base into the holding tank.  So, the AWN is out of commision right 
now until the service contractor can come in to drain the tank and 
refill the base.  They are due in at any moment now (supposedly, some 
time this morning), but in the meantime, all stations which use the AWN 
will remain unavailable for use.  We'll send a note out when the AWN 
system is repaired.  The cause of the glitch and ensuing effects are 
under investigation now.

(By the way, many thanks to Eric P, who shutdown the acid and developer 
stations last night, thereby helping to prevent an overflow situation.)
