Ms. Susan Burgmaicr <br />November I, 1995 <br />2 <br />New drainage channel <br />The 006-NE-I drainage channel, as shown on Exhibit 20-2, Post Mining Topography, <br />will be extended in a northeasterly direction from point JJ approximately 2200 ft. The <br />006-NE-2 drainage channel will be moved to the southeast and the overall length <br />shortened by 100 ft. Both these drainages end in the exact junction where the post mine <br />plan states, at point BB or sedimentation pond 006. <br />Drainage channel statistics <br /> APDrovtd Ext_ sung <br />006-NE-I Posl mine length 3500 ft. 5700 fl. <br />Post mine upper elev. 7550 7685 <br />Post mine slope "/" I2.8 "/~ l0 2 % <br />006-NE-2 Post mine length 3350 ft. 3250 fi. <br />Post mine upper elev. 7700 7700 <br />Post mine slope ".b 14.3 "/~ 14.R °b <br />Notes: I.
