Page 2 Feb. 3, 1986 C. Farrell Insp. Resp. Snyder In future operations, we will be stripping soil back of the limit of excavation so that soil lass is minimized. Of course, the soil which currently rests along the tops of the highwalls will probably not tie able to be saved because operating equipment that close to the top of a wall is rather dangerous, to say the least. However, we will go bs.ck a safe distance behind the edge and start the new stripping procedure. 3. Access and haul road berms should be maintained to minimize affected land runoff from traversing undisturbed lands. RESPONSE: The berms along side most haul roads are not there to keep water from running over the side. They are there to keep trucks from running over the side. In most instances, retention of runoff on the road through the use of berms will not work from two standpoints. First, in a large flow the water will find its way through the safety berms and second, having a river of water running down a steep roadway is not a good use or control of runoff. The best approach is to have the runoff as well controlled as possible so the sediment load carried off the road is not excessive or the sediment that does flow off the road is caught and settled prior to entering major waterways where more problems can be caused. We have been examining, for some time, the sediment control methods at this quarry. In general, this quarry exhibits better control than any other operation we have observed. The large sinkhole catches most of the sediment naturally. Onlq that area below the berm is unprotected. We have considered several procedures to help correct the problem here, which, quite frankly, is not very serious. We have even considered building a sediment pond of some sort in the drainage below the area most affected by runoff. If you would wish to discuss this matter further, we would be happy to meet with you on the issue. We have not actually found any methods that would rather simply control the problem. However, we do want to emphasize that sediment deposition on adjacent lands from this operation, in our opinion, is not a severe problem. In the interim we will try to keep the roadside berms entire. At least they will keep the smaller flows from leaving the roadway.
