COMMENTS: The SWMP control devices were inspected All SWMP wmrol devices were found
to be in good condition The sediment level in the Sanborn Creek Mine water pond cannot be
determined when the pond is full. The pond was dewatered during the third quarter 1995 and
inspected. Inflow into the mine water pond since it was dewatered and cleaned during the third
quarter 1994 has mot contained enough sediment to require the pond to be cleaned
