The RH Lab Active Sump reached the high level sensor at some point overnight before the April 8th work day.  Maico Dalla Valle noticed the alarm in the morning and notified RPG and myself.  I also received a notification by e-mail from Vicky Hannemayer who had been contacted by Ops because of the RCR alarm.

After sampling and testing by RPG the sump contents were released under work permit C2021-04-08-5 as per the procedure in Document-64834.  The approximate volume of the full sump is 7270L.
