COMMENTS
An aerial inspection of the Carbon Junction Mine was conducted on Friday, January 4, 2013.
Photographs were taken by Harry Ranney and were analyzed by Marcia Talvitie of the Division.
The permit area was covered with snow, and skies were presumably clear.
EXCESS SPOIL and DEVELOPMENT WASTE—Rule 4.09
Placement; Drainage Control; Surface Stabilization:
• The Previously Reclaimed Spoil Area(PRSA), identified in Photo 1, occupies a segment of
the original drainage for Carbon Junction Canyon. No evidences of instability in the PRSA
were observed.
FISH and WILDLIFE—Rule 4.18:
• Wildlife tracks (probably mule deer) could be seen in the snow, criss-crossing the reclaimed
areas of the permit.
HYDROLOGIC BALANCE -Rule 4.05
Drainage Control 4.05.1, 4.05.2, 4.05.3; Siltation Structures 4.05.5, 4.05.6; Discharge Structures
4.05.7, 4.05.10; Diversions 4.05.4; Effluent Limits 4.05.2; Ground Water Monitoring 4.05.13;
Surface Water Monitoring 4.05.13; Drainage—Acid and Toxic Materials 4.05.8; Impoundments
4.05.6, 4.05.9; Stream Buffer Zones 4.05.18:
• The alignment of the riprap-lined Carbon Junction Permanent Diversion Channel can be
clearly seen in Photos 1 and 2. The channel carries flow around the northern side of the
PRSA and delivers it to a small, natural side drainage that feeds into the undisturbed Carbon
Junction Canyon, downstream of the permit area.
• The general locations of three wells are indicated on Photo 2. Well B 10 was reclaimed in
2012, as discussed in the Division's December 2012 inspection report.
