QUARTERLY COAL WASTE BANK INSPECTION REPORT CDMR Rules 4.09.1(11) and 4.10.2(2) Mine: Southfield Mine Waste Bank MSHA ID. Nc Primary Refuse Disposal Area Inspection Period: Fourth Quarter 2003 Inspection Date: December 24, 2003 General Description or Reference to Site Plan: The refuse area lies west of the main facilities area. Refuse has been placed in designed lifts on a relatively flat terrain. Upslope runoff is diverted away from the disposal area, while runoff from the disturbed area is channeled to a sediment control pond. The majority of the refuse disposal area has been reclaimed previously and exhibits good vegetative growth. The mine is now in final reclamation and the all remaining disposal areas have been sloped to final grade, covered with topsoil, and seeded. Activity During Inspection: The area was idle at time of inspection. It is evident that all areas have been regraded to final contour and covered with subsoil and topsoil material. The operator reported that the areas previously seeded with an annual cover crop to help stablilize the slopes had been seeded with the approved reclamation seed mix earlier this quarter. Erosion on the side-slopes was minimal. Drainage: (Discussion of springs. seeps, overland and channel flow, underdrain construction and/or discharge, integrity of 1 o0-year 24-hour drainage structures, and evidence of positive drainage). No springs or seeps were observed on the refuse surface. Positive drainage leas been maintained on the reclaimed areas. Drainage and diversion structures were intact. All required underdrain construction has been completed. Observation of Fill Construction: (Description of material, compaction, lift thicknesses, slopes, and construction methods). No refuse placement has occurred since December of 2000. Prior to cessation of mining, waste material was placed in alternating lifts of fine and coarse material in accordance with the plan as described in the TerraMatrix report dated December 5, 1996.
