They don't need to visit the outfall daily if they can take their effluent samples near the WWTP.
However, they do need to perform instream sampling weekly. Can they get the U&D samples despite the beaver dam?

Charles,
I have review the documents you've sent me. Everything looks good. I have one concern though. The right of way to the
outfall is flooded from beaver activity. The ORC stated that it is at least 200 yards from the treatment plant to the
discharge point. Is it required to see the discharge point daily? If so, they will need some way to access the discharge
point.
