Re: Request for Vacation of Coal Program Notice ofViolation CV-2007-005
Oakridge Energy, Inc., Carbon Junction Mine (Permit C-92-080)
Background
The Division received the above-referenced request for vacation on October 10, 2007. Notice of
Violation CV-2007-005 was issued on September 4, 2007, based on an inspection of the Carbon
Junction Mine on August 14, 2007.
The inspection found that a set of dual culverts was blocked with sediment and the ditch at the
inlet end of the culverts (East Collection Channel) was filled with sediment. Debris downstream
from the culverts indicated the blocked culverts caused the flow of sediment beyond the
approved disturbed azea. Further investigation found the culverts were not documented in the
coal permit application.
Notice of Violation CV-2007-005 was issued to Oakridge Energy, Inc. (Oakridge) for failure to
minimize disturbances to the prevailing hydrologic balance at the mine site and in associated off-
site azeas, and failure to maintain a set of dual culverts. This NOV was modified on October l2
to include the permittee's failure to maintain the East Collection Channel, and failure to retain
sediment within the disturbed area. Statutes, regulations, and permit sections cited were: 34-33-
120(2)(j)) [minimization of disturbance to the hydrologic balance], 4.05.1(1) [minimization of
disturbance to the hydrologic balance], 4.05.3(1)(e) [performance standard for diversions
draining less than one square mile], 4.05.4(1)(b) [performance standard for diversions draining at
least one square mile], and permit pages 5-17 and 5-18 [certification and inspection]. An
additional regulatory citation (4.05.5(2)) was added to the NOV on October 12.
Abatement steps aze:
1) Submit a Minor Revision to identify all culverts in the East Collection Channel not
currently identified in the coal mine permit and reincorporate into the coal mine
permit those sections of the East Collection Channel that currently lie beyond the
boundaries of the coal mine permit;
2) Clean out the subject set of dual culverts in the East Collection Channel;
