Pond DP-1 is the primary pond for the entire facility area. The pond's embankments were stable and vegetated.
The primary discharge is a riser pipe with the inlet was partially surrounded by cattails which have the potential to
impede flow through the pipe and should be cleared around the inlet.The emergency spill way was well armored
with rip rap and a concrete cutoff wall.The main channel from the intermediate facility bench was stabilized with
rip rap.No cutting or instability was observed. The secondary channel for the same facility bench was also stable
and showed no signs of cutting. The beginning of the secondary ditch is constructed with a rock check dam as
additional sediment control prior to entering Pond DP-1.
Ponds PP-1 and PP-2 collect partial runoff from the facility area. PP-1 is an in situ pond located just below the
refuse bin and truck loadout. Pond PP-2 is semi-in situ with its main embankment stable and vegetated. The
spillway is a combination primary/emergency riser pipe spillway. Both ponds were stable and no issues were
noted.
B-Seam Dewatering Pond pump was not operating during the time of the inspection. The B-Seam Dewatering
Pond consists of series of 6 primary ponds that leads into an artificial wetland before reaching a final pond called
the Last Chance Pond.At the time of the inspection,water was present up to the 4th cell where it is then being
pumped to the artificial wetlands section.Water had not reached the Last Chance Pond and stayed within the
wetlands section before settling out.The Last Chance Pond was dry. To the date of this inspection,no water has
been discharged from the Last Chance Pond.
Ponds SS-1 and SS-2 collect runoff from the Slot Storage. Both ponds' primary spillways are trickle tubes.
Spillway inlets were clear of debris with stable and vegetated embankments. SS-1 and SS-2 were both dry at the
