111. COMANENTS - COMPLIgNC~
Below are comments on the inspection. The comments include discussion of observations made during the
inspection. Comments also describe any enforcement actions taken during the inspection and the facts or
evidence supporting the enforcement action.
This was a partial inspection conducted by Janet Binns of CDMG. Weather was clear and dry. Most of
the snowpack has melted off the site. A few minor snow patches remain at higher elevation of the mine
and in tree or concentrated shrub areas.
goads Permanent roads remain in good repair. Only lower roads were accessed. The eastern access
road in Eckman park was not accessed due to remaining snow and soft conditions on the road. No
major gullying or Hitting was noted on the access road to area 41. Area 41 road ditch is generally in
good repair. Rip rapped sections have withstood snowmelt runoff. Downcutting of the roadside ditch
upslope of the rip rapped sections have occurred. Realraping of these portions of the ditch is
recommended.
gydrolovic Balance Pond A was discharging. Water level in pond ie to top of primary riser. Spoil
springs at OSB 1 and D Comp (A2, B3, C 1, C2) flowing. Flow estimated at greater than 35 gpm.
Measurements taken at D Comp were: pH = 7.3, EC = 3230 ug/1 Measurement were taken with DMG
pen meters. Meters were calibrated at 7:00 am 5/1/98. Composite Ilow from spoil springs was not all
passing through D Comp weir. Volume of flow not legible on weir ataffgauge. No Measurements
taken on spoil spring flow from OSB# 1.
Permanent drainages throughout mine site were inspected: PG9/10-I aec.A and PG9/10-1A were in
good condition following Spring snowmelt. Stockpond 51 a held a small amount of water. No problems
noted with this stockpond. PG 7-1 Sec.B just downslope fmm stockpond 7a, has experienced approx.
18" of downcntting. Placement of mck check dams was discussed with operator to retard fiuther
downcutting. Stockpond 7a holding water, no problems noted with this stockpond. PG 7-1 sec. C in
good condition. Stockpond ?g holding a small pool of water. Drainage upslope of 7g is sparsely
vegetated but does not exhibit signs of gullying. Riprap at spillway of 7g needs spreading. PG 7-1 sec
B North of permanent road is exhibiting some downcutting. Placement of rock check dam or other
erosion control measures were discussed with the operator. Stockpond 51 d is in good repair.
PG 51-1 sec. A is in good condition. PG 7-1 Sec.A ie in good condition. Stockpond S 1C is slightly
seepy at the toe of the embankment. Pond is holding water. Some downcutting has occurred at the inlet
to this pond but it is of limited extent. No maintenance of stockportd 51 C is required at this tune. No
problems noted on PG51-1 Sec.B. No problems noted with stockpond S lb. Stockpond S lb was
holding water and discharging slightly (visual estimate <1 gpm).
The intersection of PG31-2 Sec.A and 31-2C Sec.A has experienced approximately 24" of downcutting.
Placement of rock check dams in this location was discussed with the operator.
PG31A Sec.C has experienced some downcutting above stockpond 31f, this cutting is limited and does
not require maintenance at this time. Stockpond 31f contains water, although is not discharging
through the spillway. Water apparently seeps out raider the embankment. PG31A Sec.B. is in good
condition. Stockpond 311r appears in good condition. A pile of riprap has been left adjacent to the
spillway. PG31A Sec. A and PG31-1 Sec. A appear functional. Stockponda S1Wb and S1Wa are
holding well. Repairs on 51 Wa completed in 1997 appear to be functioning well.
