On September 28 and 29, 1993 a complete inspection was conducted at the Marr
Strip Mine. Present at the inspection was George Patterson of Kerr Coal and
Randy Price of the Division. At the time of the inspection the weather was clear
and warm.
Records were checked September 28 and were in order. The mine site was
inspected September 29.
Two Antelope were noted crossing the access road between drainages D and E.
The fuel storage areas were inspected. These areas were free from spills.
Storage tanks were stored in bermed and lined storage areas. These areas were
clean and did not contain ponded water.
The eastern portion of the facilities pad had a 6 foot high berm. This area was
regraded earlier this year as an abatement to a violation. The 18" flexible fabric
pipe installed this year, used as a drop structure from the bench to Ditch C-1,
appeared to be working adequately. There was evidence that a little bit of
water has flowed through this pipe. At the bottom of the drop structure, where
it enters ditch C-1, there was a small incised area lined with river rock. The
locatio of this drop structure is about 15' north of the previous ditch. Areas of
ditch C-1 that were eroding earlier this year had been lined with rip rap. Ditch
C-1 was stable.
Pond C was totally dry. Embankments were stable. There was minor rilling on
the outslopes of the pond. The discharge structure and flume were level and
appeared to be functioning properly. The channel leaving the outlet was well
vegetated.
The explosive storage area was inspected and no concerns were noted.
Pond B contained a good amount of water; about 66% of the aerial extent of the
pond was covered with water taking up only about 10% of the pond capacity.
The principal spillway was in good condition, and the emergency spillway was
well rip rapped with river rock. The sediment level was about 4 feet below the
first dewatering hole.
Topsoil and subsoil piles north of pond A were signed, well vegetated and stable.
Pond A has about 25% of the aerial extent of the pond was covered with water.
The general profile of the overburden pile is now gentle slope. Seven motor
graders were working the pile. Work was being concentrated on the south end
of the pile. The water level in the 720 pit is rising because of displacement
from the fill material. The water was an olive-brown and was muddy looking.
The culverts under the mine access road to pond D were in excellent wndition.
The ditches and culverts in this area appeared to have been recently worked on.
