PART IV - EVALUATION AND RECOMMENDATIONS
This application is for the renewal of an existing
permit that serves a single family residence. Since the
last permit was issued, a chlorinator and contact unit has
been installed (July 1988 ) . This system began to
malfunction in early 1990 and was refurbished in June 1990 .
No problems were observed at the time of the inspection.
The outfall line runs across the property at 118
Creekwood Drive and discharges beside the stream culvert.
The USGS map has been photorevised and indicates that the
ctl identified on prior staff
discharge point was incorrectly
reports. The revised coordinates are listed on page 1 .
It is recommended that the permit be reissued.
