The following ponds were inspected: Prospect, Gulch A,Rail Loop, Gossard, Stoker Siding,Work Area,and the
ponds near the main facility area. All were holding water—some in the form of snow only and some contained
liquid water as well. The sediment sump was discharging to the Wash Bay Pond. The Stoker Siding Pond was
discharging a very small amount of water;no sign of pollutants was observed. Some observed ponds were not
discharging: Work Area,Wash Bay, and Rail Loop. The following ponds appeared to not be discharging (based
on level of snow versus the primary spillway),but this could not be confirmed because the outlet of the spillway
was covered with snow: Prospect,Gulch A,Gossard.
No problems were identified with embankments, spillways,or other aspects of the ponds.
The sump at Gossard pond has been cleaned recently. The area around the pond has very little snow and the
ground is covered with a significant amount of coal dust.
Several sediment traps along the lower end of Taylor Creek Road were observed,none appeared to be discharging,
and no problems were seen. All were holding snow;the trap nearest the haul road contained liquid water as well
as snow.
