® a <br /> -14- <br /> o�" <br /> rock from ~line No. 3 had a high nickel value. The high iron levels 3n <br /> the high nickel value should not pose a significant problem beca,jse bowl <br /> iron and nickel are relatively insoluble at the pH values <br /> characteristically found in the materials and water associated with t. ,.. <br /> materials. In addition, the sodic nature of the materials is not a <br /> significant problem. High sodium levels would not affect the plant Y� <br /> growth characteristics of the materials since these sodium quantities are <br /> not toxic to plants, but rather would destroy the structure of soils, <br /> particularly in soils of predominantly clay texture. The result of this <br /> breakdown is a decrease in the infiltration rate, thus a decrease in - <br /> water available for plant growth. However, the coal processing waste (a <br /> combination of coal and roof rock) , which may be subject to revegetation <br /> ,activities is coarse textured, thus there should be no problems. <br /> The proposed operation is in compliance with the requirements of this <br /> section. <br /> V.

East Muddy Creek flows west into <br /> the confluence with the North Fork, which flows west to the confluence 1IXx <br /> with th-a Gunnison Rider. The Gunnison river joins the Colorado River in <br /> Grand Junction, approximately 70 miles west of the Coal Basin facilities. <br /> he primary stream in Coal Basin is Coal Creek, a perennial stream, which <br /> is tributary to the Crystal River. This stream grains an area of <br /> approxiniat'?ly 25.5 sgraar,� itilf,s. T;la strea.ns tri5litary to Coal Creak <br /> whose upper- drainayes originate in the mine lease area are, in clocl<witi-� <br /> direction around the basin starting from the lower end, Bear Creak, Sor,t;i <br /> Forr Jutch Creek, North Fork Dutch Creek, Oilwell Creek, Co.31 (;r ��f, and <br /> Porcupine Creek. Each of these streams is ephemeral on the lease -Tact <br /> and becomes perennial down gradient toward the plant site. Other streams <br /> in Coal Basin outside of the Coal Basin ;pine affected area are Spring <br /> Creek ana Broderick Creek.
