This damage is in an azea at the northern end of the waste pile. Sierra has committed to no dumping of waste blocks of marble on the waste pile in areas that might impact the northern end ofthe waste pile until the damage is repaired. The sediment pond was also damaged by CYMC's activities. Sierra has committed to no dumping of saw cutting fines on the waste pile until the sediment pond is functional. Sierra will be working with the Division to coordinate the repair of the sediment pond with the repair ofoff- site damage as it may be that the sediment pond repay will be included in the repays funded by the CYMC bond.

During the spring and summer of 2001, Sierra may establish a test plot to determine the need for topsoil in areas that aze planned for revegetation in the future. Sufficiency of Value of Fiuaacial Warrantee: There has been no significant surface disturbance during the year and the reclamation plan has not changed. Therefore the financial warrantee of $40,258 should not need adjustment. Sierra has funded the Financial Warrantee with a Reclamation Bond. Sierra has paid its premium for the following year.
