Scott Wanstedt of Blue Mountain Energy informed the inspector that the mine site received 1.07 inches of
precipitation on 7/7/10. The operator indicated that this volume fell within a half hour. Consultation with the
NOAA atlas finds the 10-year 24-hour storm at this location equates to 1.6 inches.This storm event resulted in
erosion on the ditch from the rotary breaker to pond DP-1. DP-1 Pond discharged from primary spillway.The
pond was not discharging at the time of the inspection.The water level of the DP-1 pond was about 1/2 inch below
the discharge elevation.The primary spillway outlet has sediment covering about 2/3 of pipe [photo I].The ditch
from rotary breaker to DP-I had down cut. Round river rock armoring had washed downslope.This material had
deposited on the slope adjacent to the pond and in the lower part of ditch.Very little rock had made it to the pond.
BME will need to dress up the ditch as mine site maintenance. BME needs to find a way to anchor the rip rap so it
does not wash down.Treatment of this ditch was discussed with the operator.Removal of the rock from the slope
