(C) Existing Forest Service owned or permitted surface improvements will need to be protected, i:estored or replaced to provide for continuance of current land uses. With specil:ic regard to the Bruce Park Reservoir and dam, shou:Ld structural damage result from mining-related activities, the lessee shall be responsible for damage repair and compensation to the injured party or parties. (D) The structural integrity of the coal in the chain and barrier pillars under Terror and F[ubbard Creeks shall be designed andmaintained for long term support. Backfilling or structural supports may be required to achieve long term support under the creeks and the structure upon retreat mining. A pillar stability analysis shall be used to design chain or barrier pillars for long term structural integrity where needed to protect surface z:esources, (g) Transportation of Coal. The lessee will have thirty (30) months from the date of lease issuance to obtain alternative means for transporting the coal from the mine to the rail loadout. After that date, no Federal coal from the lease will be transported via truck on State Highway 133 with the exception of. specialty coal and instances of force majeure.

(2) Specific approval will be required for locating drill sites, degasification boreholes or ventilation shafts or any other surface disturbances (if they are needed) in areas of moderate geologic hazards and on slopes ranging from 40 to 60 percent. (3) Drill sites, degasification boreholes, ventilation shafts or any other surface disturbances will not be located on slopes in excess of 60 percent, or in areas of high geologic hazard. (4) No surface occupancy or use will apply to all wetlands, f7.oodplains and riparian areas on the National Forest. (5) With regard to protecting elk on the winter range during calving season, and minimizing surface damage, no surface use {exploration, drilling and development activity) will be allowed from December 1 to June 15.
