interim needs of the Bonanza Station, about 60,000 tons of coal per month were purchased from <br />the Colowyo Mine. The coal was trucked to a laydown area constructed near the transfer station <br />#2 and reclaimed by a stacker conveyor to the overland conveyor no. 3 (CNV3). This temporary <br />measure lasted through April, 1997 while a new longwall system was being made operational. <br />The site includes a pond to contain a 25-year, 24-hour event and 900 feet of access road. Map <br />149 shows the design of the sediment pond. Figure III-4 shows the layout of the laydown area. <br />The temporary access road construction followed the typical road section shown on Map 67 of the <br />permit. BME plans to maintain the temporary coal laydown area as a contingency until the end of <br />the project. This will avoid the potential for future disturbance should another failure in the coal <br />supply occur. <br />III.C. Auxiliary Facilities <br />The major disturbed areas consist of the Ventilation Entries (also referred to as East Exhaust <br />Portal), the D Portal area, the Refuse Disposal area and the B-Seam ventilation shaft facility. <br />The ventilation entry area for the D coal seam is shown on Map 139. In order to effectively use <br />the site, the old Staley tipple building was dismantled by outside contractors. All metal (steel and <br />tin) was hauled off site and disposed of by the contractor. Concrete footings and foundations <br />were left in place. During excavation/grading, the grade was brought up to a level even with the <br />concrete foundations so there would be no problems passing over the foundations in vehicles. <br />The material storage site is located near the entrance to the old Staley Gordon Mine. <br />Due to previous contamination and misuse by the Staley Gordon Mine, there is no suitable topsoil <br />in the area to be saved. A dozer was used to level the space and form a two foot berm for <br />sediment control at the low elevation of the site. Illustration 41 shows that a 2' berm is adequate <br />and that the site is well above the 100 year flood level. Additionally, a 1.5' ditch was cut above the <br />site to divert undisturbed clean water around the site. <br />During final reclamation, the site will be restored to approximate original contours. Four inches of <br />topsoil will be imported from the D-Portal area and spread on the site. Table V-4 reflects <br />importation of topsoil. After topsoil has been spread, the seed mixture as shown in Table V-14 will <br />be planted. Reclamation standards in the permit that apply to reclamation of the ventilation entry <br />will also apply to the material storage site. <br />Permit Renewal #3 (Rev, 8/99) III-32 <br />
