• 2.05.6(6) are relatively steep. Flow through the drainages could temporarily be effected by a subsidence crack across a stream channel, however, the crack would be expected to heal fairly quickly so the surtace drainage pattern would be naturally restored. Very little flow has been recorded for the various ephemeral and intermittent steams in the permit and adjacent area. These streams are expected to be typically dry with flow occurring during spring snowmelt and after significant precipitation events. Therefore, short term disruptions in the flow from these streams should have very little impact on the water budget for Hubbard and Terror Creeks. • Hubbard Creek could be damaged by subsidence cracks which would cause it to run into the mine below. It may be possible to repair a stream that is affected by a crack. First the flow interrupting crack would have to be located. Then a culvert would be installed to divert the water from the crack. Then the crack would be sealed with a impervious liner or other material. (b)(iii) The description of the worst possible subsidence consequences has determined that material damage and diminution of reasonably foreseeable use of renewable resources could result in the event of mine subsidence within the permit and adjacent area. Therefore, the operator has prepared a subsidence control plan in accordance with Rule 2.05.6(6)(b)(iii)(B) (b)(iii)(B) A subsidence control plan, as described in Section 2.05.6(6)(f). • (f) A description of the subsidence control plan, prepared by appropriately qualified professionals follows: (f)(i) A description of the physical conditions, such as depth of cover, seam thickness, and lithology, which affect the likelihood or extent of subsidence is presented in Volume III, Exhibit 15. The depth of cover data is presented on Map 27, Subsidence. PR-oa 2.05 - 105 - 01/01
