Nor was there any dust being tracked onto the public roads at the unit train loadout or at the East Mine . For most of the sites, the vegetative cover is holding down any dust problems. BACKFILL and GRADING – Rule 4.14 Contemporaneous Reclamation 4.14.1; Approximate Original Contour 4.14.2; Highwall Elimination 4.14.1(2)(f); Steep Slopes 4.14.2, 4.27; Handl ing of Acid and Toxic Materials 4.14.3; Stabilization of Rills and Gullies 4.14.6: At the East Mine, the operator had recently roughened up the ground surface of some of the backfilled and graded areas so that the reseeding of those areas would have a be tter chance of success. Since the last inspection, the operator had hydroseeded those areas. 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 sediment control at the entrance to the East Mine was in place, although some of the silt fence along the road corridor needs a little repair. The operator had recently added to the number of cross ditches along the road. The operator also had repaired the riprap in the collection ditch section that li es just to the west and, also, just below the backfilled portal bench area. This had been an issue during the OSM federal inspection on May 26, 2011. However, the Division was concerned that the bottom of the channel was covered in dirt, not riprap. The op erator, in response, dug several trenches in the bottom of the channel to confirm that riprap was below the dirt at the bottom of the channel (Figure 1 and Figure 2). The riprap in the remaining sections of the collection ditch also was in place.
