they clean the claifier overflow area D/S of the metal weirs w/12% bleach solution.
per DJE, they monitor TRC about 45 min after clarifier is returned to service (this is about 4 hr after cleaning)
I asked them to check TRC every 5 min for 1 hr, after clarifer is returned to service - send results of several monitoring events for me to review
this will help determine when TRC should be monitored
