~J 2.05.6(6) A limited extraction zone was established along the bleeder entries in the vicinity of Freeman Gulch and the vent shaft in Freeman Gulch to assure ancient land slides were not reactivated by subsidence. A detailed subsidence study for Terror Creek Reservoir and dam will be completed prior to any mining within one mile of the reservoir according to the schedule outlined above. Mining in low overburden areas adjacent to the possible fault trace is explained in section (f)(ii)(B) above. (f)(iii)(C) The Operator will protect its facilities from rockfall by constructing three berms at the location shown of Map 15-2 and in accordance with the design presented in Volume VII, Tab 11. No other protection measures are proposed. • Subsidence monitoring stations are not proposed to determine when the potential for rockfalls might diminish. The Operator will assume rockfall hazard continues for two years after an outcrop is affected by mining. (f)(iv) A detailed description of the measures to be taken to mitigate the effects of any material damage or diminution of value or foreseeable use of lands which may occur. A subsidence handbook is presented in Volume III, Exhibit 15. This handbook addresses the necessity for repair and restoration as well as repair and restoration procedures for surface streams, ponds, springs, groundwater, landslides and roads and trails. Additionally, any surface improvements (existing or permitted) which are damaged or destroyed by subsidence will be restored, rehabilitated or replaced by the Operator. With respect to the Bruce Park Reservoir and dam, should structural damage result from mining-related activities, the Operator will repair the damage and will also be responsible for damage to injured parties. If deemed necessary by the DMG and the surface • management agency to provide for continuance of existing land uses, land- TR-031 2.05 - 110 - 02/04 /~PPRovEn S/rr/o 4
