The work consisted of regrading the top bench of <br />refuse to establish a suitable final subgrade, covering all exposed refuse with 4' of cover, <br />extinguishing an old fire west of the pile, establishing a rip rapped channel and seeding. <br />The cover material was excavated from the upper wash plant pond to eliminate importing <br />soil. Other factors reducing the covering cost was the work previously done while the pile <br />was being constructed and the smaller total disturbed area than permitted. The remaining <br />earthwork at the site is eliminating the refuse pile sediment pond and establishing a rip <br />rapped channel across the reclaimed pond. <br />The revegetation work in the fall of 1986 involved seeding, fertilizing and crimping straw <br />mulch where possible and broadcast seeding, fertilizing and netting straw mulch on the <br />steeper slopes. <br />• 4-71 Revised June 1998 <br />RN-o3 <br />TR-ao <br />
