West Taylor Fill with A -A' and B -B' Underdrain Area Since the last quarterly inspection, topsoil has been placed from the 7840' elevation down to the previously reclaimed surface at the 7705' elevation. The east tributary of the West Taylor fill has been rip- rapped from the 7695' elevation up to the 7810' elevation (approximately). The west tributary of the West Taylor fill has remained unchanged, with rip -rap placement up to the 7695' elevation. Dumping continues at the 8050 elevation of the temporary out of pit fill.
