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 of the Southfield Mine. The purpose of this inspection
was to follow-up on the Phase I Bond Release inspection conducted on 13
November 2002. The Division brought out a team to survey areas that were in
question from the previous inspection. The inspection was performed by Jim Stark of
CDMG. Sandy Brown, Harry Ranney and Byron Walker of CDMG, George Patterson
and Rich Munson of EFCI, Dr. Doug Corley, Anne Corley, Carin Corley and Daryl
Mergen of the Corley Company and Linda and Bob Saunders accompanied me.
The weather was cool and sunny and the ground was dry.
Hydrologic Balance: -Pond 4 was dry at the time of the inspection. The pond was
stable and well vegetated. The pond has been converted to a self-dewatering
pond. The Division surveyed the top of the discharge pipe and its elevation was the
same as the elevation sfated on the as-built map.
-Pond 5 was dry at the time of the inspection. The pond was stable and well
vegetated.
-The Magpie Creek permanent diversion was walked and surveyed on the
inspection. There was an area about 100 feet long (approximately 325 feet upstream
from the steep, riprap armored section) that had a slight rise of approximately three
inches. The Division believes that this slight rise is insignificant. The Division will
evaluate this area regularly to ensure that the diversion is functioning properly. The
Division received a request from the Corley Company that they wanted the large
pieces of concrete left on the bank of the diversion for slope protection.
-The South Fan small area exemption (SAE -sediment fence) was properly installed
and appeared to be functioning. The drainage from the regraded South Fan all
flows through this SAE. In conjunction with the 2002 midterm, the Division received a
new SAE demonstration for the area and its post-mining (reclamation) conditions.
- The explosives bunker SAE (straw bales) was properly installed and appeared to be
functioning properly. The drainage from the regraded explosives bunker area flows
through the SAE.
-The 100-year diversion ditch around the refuse pile was surveyed at the time of the
inspection. The ditch has positive drainage its entire length with one small exception.
There is a short (50 foot) section on the extreme northwest corner of the refuse pile
that has a slight rise of less than one inch. The Division will evaluate this area regularly
to ensure that it is functioning properly. All of the drainage from the refuse pile will
flow into this ditch and ultimately into pond 4.
-All of the drainage from the borrow area flows into the 100-year diversion ditch and
into pond 4 as well.
- The drainage from the regraded pond 3 area was also surveyed. The slope of the
area ranged from -0.21% to -1.72%. All of the drainage from this area flows to the
northeast. First it will flow through straw bales then through a sediment fence. The
straw bales and sediment fence both appeared to be functioning properly and both
were properly installed. There is still a piece of PVC pipe below the sediment fence
