<br />nature of the area, and its slope of 1~. Assuming a soil grouping <br />of D from the Mancos Shale in which most sugar beets were raised <br />and good rangeland once vegetation is established, a CN of 60 <br />would account for 0.15 acre-feet. of run-off in a 10-year 24-hour <br />storm. Drainage from this area and the office area would <br />naturally flow into an existing depression northeast of the office. <br />The surface area of this depression is 0.5 acres; therefore, the <br />water level could be raised 11" by the exempted 0.47 a,f. of runoff. <br />The emissions permit and addenda are in Figures 2.05.6(1)(a)-2 <br />and 3. The Letter in Figure 2.05.6(1)(a)-3 and accompanying map <br />referred to the large fines pile and the working inventory pile. <br />These piles were located on the area south of the office, which <br />is now excluded from the permit boundary. The long pile northwest <br />of the screen is the present south stockpile. The location of <br />this south stockpile being 450' away from the closest resident <br />will reduce the emissions from the loadout facility. Watering of <br />the roadways and the application of dust suppressants to the <br />stockpiles will be done as needed to control the dust. <br />(8) Coal Processing Waste and Non-Coal Processing Waste <br />A narrative describing the construction, modification, use, <br />maintenance, removal, and reclamation of coal processing and non- <br />coal waste removal, handling, storage, transportation and <br />disposal areas and structures in the permit area. <br />Not applicable. <br />REVISED August 21, 1989 <br />120a <br />
