• <br />WEST MINE NORRfS POND <br />Note: With regard to the sediment contribution of the Railroad grade, sediment <br />area and runoff will be calculated ro the center line between the two <br />rails. WSC cannot control sediment nor runoff from the south portion <br />of the rail due ro its severely limited land situation. It is felt that no <br />sediment will be produced from rainfall striking the track ballast, and <br />that attempting to dig a 2700' long ditch contributing to another sedi- <br />ment pond would create more sediment that it would control, resulting <br />in a net particulate pollution increase. <br />J <br />• <br />
