PART IV - EVALUATION AND RECOMMENDATIONS
There was no discharge on the day of the inspection. There
wasn't any odor or discoloration of the receiving stream. There
was a very small amount of running water in the stream, even
though it has been an unusually dry summer.
Since this is a single family residence with a low flow and
no adverse effect on the environment, the regional office does
not object to the reissuance of this permit.
