-°- <br />7b illustrate the areal <br />effects that wuld <br />(approx. 3 months) the <br />Production Rate: <br />extent of possible subsidence <br />occur in any one grazing season <br />following example will be used: <br />Nianber of t4iner <br />Units Operating: <br />Size of Retreat <br />Panels (adjusted <br />for angle of draw <br />@ 1200 ft over- <br />burden): <br />Approximately 1/2 of <br />retreat panel length <br />can be retreat mined <br />in 3 months: <br />1.4 million tons per yeaz <br />5- 2 development <br />3 retreat <br />(asstane panels are not adjacent <br />to each other) <br />144 Acres (approx.) <br />144 AC x 3 panels x <br />1/2 in season = 216 acres <br />potentially affected in <br />one season. <br />This example represents a worst case condition since <br />adjacent panels decrease cwnulative azea affected. This <br />example does not take into account areas of overburden <br />less than 1200 feet i.e. as overburden depth decreases <br />amount of azea affected decreases due to angle of draw. <br />Total c~amilative acreages to be affected by subsidence are <br />contained in the Mt. Gunnison Mining and Reclamation Plan, <br />Voltane 1, pages 1-158 and 1-159. <br />WF7LC as stated in the permit application and <br />adequacy response has a contingency plan which <br />calls for: 1)repair of the damaged water resource <br />ie. repairing of a leaking pond, etc. if possible. <br />2)development of alternate supply at a nearby loca- <br />tion. <br />YII~70C will further agree that it will, since each <br />water resource is site specific: <br />1)oonsult with users, landowners, U.S.F.S. <br />District Ranger or other involved pazties <br />as to repairs, construction plans, access <br />or mitigative actions to betaken. <br />
