III. COMMENTS- COMPLIANCE Below are comments on the inspection. The comments include discussion of observations made during the inspection. Comments also describe any enforcement actions taken during the inspection and the facts or evidence supporting the enforcement action. July inspection. Additional cleanout of this ditch is needed. Ditch E-2 east of the zero entry shaft has been cleaned out, and is sufficient. Most of the ditches were dry. TCC has been conducting maintenance throughout the mine site. The NW B-O-B ditch continues to require to be cleaned out. Coal has been pushed into this ditch but all material will drain to Pond B. Visual markers may assist the dozer operator in seeing the limits of the pile. Maintenance of the BOB NW ditch needs to occur prior to winter months. TCC has graded the area south of the Wash Plant II. The ditch south of the wash plant has been mostly re-established. TCC has not established a sump on the west side of Wash Plant I1. The thickener overflow sump has not been utilized and is currently dry. 2 culverts were in place under the western access ramp to the area by the thickener tank. These 2 culverts drain the low area south of Wash Plant II as well as handle the ditch drainage to Pond D. The ramp over the east portion of this ditch does have a single culvert through the ramp. However, this culvert is clogged and no information has been provided regarding the sizing of this culvert. TCC either needs to remove the ramp and re-establish the ditch, or demonstrate proper sizing of the culvert and assure the culvert is clear of sediment. Coal material had previously been pushed outside of the berm at the Train Load Out. On 8/27 efforts to re-establish a ditch along the perimeter of the Train Load out area had resulted in a trench. The trench ranged from—6 inches deep on the east side to—4 foot deep at the deepest point. Discussions with the operator clarified that a trench was not intended to be a collection ditch. (Photo 1) The operator met with the contractor to communicate the desired ditch configuration. On 8/28 the inspector revisited the train loadout site. A front end loader was actively reshaping the trench and re-establishing a shallow ditch. Care was being taken to pull coaly material to the south of the ditch, and to re-establish the grade for positive drainage. The ditch connects to an existing ditch and rock check dam. (Photo 2). These repairs are progressing and appear to be meeting the intended purpose of the ditch. We discussed placement of visual markers to minimize pushing of coal and or snow off this pad when equipment is cleaning up the load out pad.
