Other Violations/Staff Remarks:
ORC indicated "didn't do a effluent temp on 4/25/22, due to a mechanical issue at the plant" — NOD recommended
Supervisor Remarks:
what does a mechanical issue at the plant have to do with not collecting a pH?
This is the 2nd monitoring frequency violation in 12 months for Temp. Proceed
to NOD, but if any further frequency violations occur in next 12 months,
automatic NOV.
