8. Disturbance of Spoil Placed on the Outslope <br /> The pre- law spoil outs lopes at the portal areas (see enclosed mine <br /> maps ) are extremely steep and are not accessible to machinery or- <br /> workers . Gullies do exist in some slope areas and natural <br /> revegetation has been sparse . <br /> During mine operation , Mid-Continent has not disturbed these spoil <br /> slopes . Berms and sediment ponds on the bench areas kept runoff <br /> away from the slopes . When the upper portion of the spoil slopes <br /> are excavated to obtain material for backfilling , it is possible <br /> that some material will roll over the edge . This is unavoidable and <br /> will not result in any damage to the environment . <br /> Once the cut and fill work is completed for each bench area, Mid- <br /> Continent will attempt to seed and mulch as much of the spoil slope <br /> as possible from the top of the bench . A high power blower or <br /> hydromulcher will likely be used . <br /> • <br />
