On September 22, 1994 Grand Valley Coal Company was issued a notice
of violation for the Munger Canyon Mine. The citation was for
failure to design and construct sediment control measures to prevent
additional contribution of sediment to runoff outside the permit
area. GVC does not wish to contest the citation at this time but
would like to take this opportunity to discuss the facts surrounding
the citation.
First, be aware that the sediment controls shown on the Minor
Revision that was approved by the Division on October 5, 1994 were
installed on October 6, 1994. These controls include a water bar at
the top of the Munger road and enhancement of the sediment control
structures at the fan area.
Two areas were mentioned in the citation. The area at the fan had
effective sediment controls in place. These controls included
revegetation, berms and silt fence. Grand Valley had failed to
document these controls in its permit application. This portion of
the citation was not a failure to control sediment but rather a
failure to control the paperwork. The controls were shown on the
revised Figure 2.2-4 that I gave to you on September 22, 1994.
The second portion of the citation was for the separation of water
flow between a small portion of the mine bench and the access road.
The area that could drain from the mine bench to the access road was
small, about 20 by 60 feet. This is an insignificant area when
compared with the 70 acres that drain from the area behind the mine
site. Portions of the area in question were in fact draining to the
existing SA&-1. This was evident from the drainage patterns on the
ground.
