I• <br />2.05.6(6) <br />are relatively steep. Flow through the drainages could temporarily be <br />effected by a subsidence crack across a stream channel, however, the crack <br />would be expected to heal fairly quickly so the surface drainage pattern <br />would be naturally restored. <br />Very little flow has been recorded for the various ephemeral and intermittent <br />steams in the permit and adjacent area. These streams are expected to be <br />typically dry with flow occurring during spring snowmelt and after significant <br />precipitation events. Therefore, short term disruptions in the flow from these <br />streams should have very little impact on the water budget for Hubbard and <br />Terror Creeks. <br />Hubbard Creek could be damaged by subsidence cracks which would cause <br />it to run into the mine below. It may be possible to repair a stream that is <br />affected by a crack. First the flow interrupting crack would have to be <br />located. Then a culvert would be installed to divert the water from the crack. <br />r1 <br />(b)(iii) The description of the worst possible subsidence consequences has <br />determined that material damage and diminution of reasonably foreseeable <br />use of renewable resources could result in the event of mine subsidence <br />within the permit and adjacent area. Therefore, the operator has prepared <br />a subsidence control plan in accordance with Rule 2.05.6(6)(b)(iii)(B) <br />Then the crack would be sealed with a impervious liner or other material. <br />(b)(iii)(B) <br />A subsidence control plan, as described in Section 2.05.6(6)(f). <br /> <br />(c)(i)(f) The subsidence monitoring program will extend at least two years beyond <br />cessation of mining in any area, consistent with the need for verification of <br />the subsidence prediction. The DMG must approve the cessation of <br />subsidence monitoring through a technical revision. <br />(f) A description of the subsidence control plan, prepared by appropriately <br />qualified professionals follows: <br />PR-08 2.05 - 105 - 07/03 <br />~~QOI/ED <br />p~z5~a3 <br />
