RULE 4 PERFORMANCE STANDARDS <br />During minor revision 80 a light-use road was permitted to facilitate shorter equipment movements to <br />additional areas of the northern end of the mine. This light-use road begins south of the fuel storage tanks <br />and continues in a northwest direction towards the main coal haulage road with an approximate width of <br />30 feet and a length of approximately 1200 feet. It enters the main coal haulage road just below the <br />traffic pattern crossover. Topsoil was stripped in accordance with Rule 4.06.2 and placed on topsoil pile <br />15A directly to the west of the road. Maintenance will include maintaining natural drainage across the <br />roadway and maintenance of a swale on the northern portion of the road which will transfer runoff to the <br />existing ditch. Reclamation of this light-use road will be completed immediately after the road is no <br />longer needed for operations and will be reclaimed in accordance with Rule 4.03.3(7). The road was <br />field designed in accordance with Rule 4.03.3. <br />Rule 4 Performance Standards 4.03-3 Revision Date: 6/23/08 <br />Revision No.: MR-91
