COMMENTS
The DRMS conducted a partial inspection of the Carbon Junction Mine on April 30, 2013.
Marcia Talvitie and Sandy Brown of the Division were accompanied by four representatives of
the Office of Surface Mining (OSM); their names are listed on the first page of this report. The
mine was selected by the OSM as part of this year's Special Focus on Reclamation Success:
"Stream Channel and Drainage Reconstruction". The inspection evaluated the various reaches of
the Carbon Junction drainage system within the permit area.
We arrived at the gate at 9:40 a.m. Skies in the morning were clear, but the wind picked up in
the middle of the day, and continued to build in intensity. By the conclusion of the inspection, at
2:25 p.m., the skies had become opaque with dust blown in from Arizona and New Mexico.

Carbon Junction Canyon is an ephemeral drainage that bisects the permit area from northeast to
southwest. The drainage area is less than one square mile in size. Disturbed areas tributary to
the drainage are located on both sides of the channel.
Permanent placement of overburden spoil was previously approved within a segment of the
Carbon Junction drainage. Placement of this material (now termed the "Permanently Reclaimed
Spoils Area", or PRSA) necessitated that a permanent diversion of the Carbon Junction drainage
be constructed. This diversion skirts the northern limit of the PRSA.
To conduct this inspection, the group parked at the location where twin 66" corrugated metal
pipes (CMPs) carry the Carbon Junction permanent diversion channel beneath the paved haul
road. We followed the riprapped channel downstream to the point where it terminates in a
