The Office of Surface Mining, Reclamation and Enforcement <br />(OSMRE), represented by J. Spencer Shumate and Tom Medlin, conducted oversight of the <br />Carbon Junction Channel portion of the inspection. The Division was given one day's advance <br />notice of OSMRE's planned inspection of this site. <br />Skies were clear and temperatures were warm. The inspection commenced with a review of the <br />Upper Carbon Junction Channel reconstruction work that was completed in 2013. Following <br />OSMRE's departure, we explored an area that the operator is likely to use as a revegetation <br />reference area. <br />HYDROLOGIC BALANCE - Rule 4.05 <br />Drainage Control 4.05.1, 4.05.2, 4.05.3; Siltation Structures 4.05.5, 4.05.6; Discharge <br />Structures 4.05.7, 4.05.10; Diversions 4.05.4; Effluent Limits 4.05.2; Ground Water Monitoring <br />4.05.13; Surface Water Monitoring 4.05.13; Drainage Acid and Toxic Materials 4.05.8; <br />Impoundments 4.05.6, 4.05.9; Stream Buffer Zones 4.05.18: <br />• An April 2013 OSM oversight of the Carbon Junction Mine resulted in the Division's issuing <br />NOV CV- 2013 -005. A significant aspect of this NOV related to the operator's failure to <br />reclaim the Upper Carbon Junction Channel in accordance with the approved plan. A revised <br />design for the channel's reestablishment was approved with TR -17 in November 2013; <br />construction was completed the same month. TR -17 text and maps were incorporated into <br />the permit as new Exhibit 5 -12. <br />• During this inspection, with OSM, we revisited the Upper Carbon Junction Channel. The <br />temporary diversion berm had been removed, with the material graded back into the southern <br />side of the westward - flowing drainage. The un -named tributary has been rip- rapped to <br />prevent erosion from occurring as runoff is carried to the bottom of the Upper Carbon <br />Junction Channel. <br />Graded slopes had been tracked and seeded. The grasses are slow getting started, but growth <br />since the May 28, 2014 inspection, just one week prior, was evident. <br />Number of Partial Inspection this Fiscal Year: 4 <br />Number of Complete Inspections this Fiscal Year: 4 Page 2 of 6 <br />
