December 18, 2013 C-1992-080/Carbon Junction Mine MLT • In November, Oakridge's reclamation contractor, C & J Rock Products, accomplished work in the Upper Carbon Junction Channel. The work was required to abate CV-2013-005; designs were approved under TR-17. • The temporary diversion berm was removed, the slope on the southern side of the drainage was regraded, the un-named tributary was realigned and lined with riprap, and the gradient of the main channel was improved.

Repair work was initiated by the operator following completion of the Upper Carbon Junction Channel project.

A series of water bars have been installed in the roadway hillside ditch to slow the velocity of any runoff.
