Page II <br />Z Resources mine (page 19). I recommend the GEI Consultants, Inc. letter of May 22, 2003, <br />a Re: Additional Analysis: Geotechnical Evaluation of Mine Induced Seismicity on Bruce <br />Park Dam, be added to Volume X Geotechnical Studies Bruce Park Dam. <br />Rule 2.05.6(6)(e)(ii) A detailed description of material subsidence damage or diminution of <br />reasonably foreseeable use of structures and renewable resource lands which could result from <br />the occurrence of subsidence related phenomena predicted in accordance with Section <br />2.05.6(6)(e)(i)(D) within the permit and adjacent area, including consideration of the following: <br />An inventory begins on revised page 2.05-99. <br />Rule 2.05.6(6)(e)(ii)(A) Material subsidence damage means, with respect to structures, changes <br />which make it technologically or economically infeasible to promptly restore the affected <br />structures to the condition they would be in if subsidence had not occurred. <br />Descriptions of possible damage begin on page 2.05-104. None of the descriptions, with the <br />exception of the Dove Cave, in my opinion, constituted material damage. The Dove Cave could <br />collapse (revised page 2.05-107). This would be material damage. <br />Rule 2.05.6(6)(e)(ii)(B) Material subsidence damage means, with respect to renewable resource <br />lands, changes which disrupt an aquifer, or a recharge area to an aquifer, which serves as a <br />beneficial use of water or changes which make it technologically or economically infeasible to <br />restore the productivity of the affected renewable resource lands, expressed in terms of food, <br />fiber or forage, to the level it would be if subsidence had not occurred. <br />There is no stratigraphic (bedrock) aquifer. However, perched water tables and soil are sources of <br />springs. Material subsidence damage is not anticipated, and is well discussed in the PAP. I <br />believe there would be no material subsidence damage to food, fiber or forage. <br />Rule 2.05.6(6)(e)(ii)(C) A determination of diminution of reasonably foreseeable use of <br />structures or renewable resource lands within the permit and adjacent area which shall consider <br />the capability of those structures and lands, before and after subsidence occurrence, to support <br />those uses described in Section 2.05.6(6)(b)(i)(A), giving consideration to factors such as soil <br />and foundation characteristics, topography, vegetative cover, surface hydrology and <br />groundwater hydrology. <br />There may be some diminution of renewable resources, and the applicant has submitted a <br />subsidence control plan (revised page 2.05-107). <br />Rule 2.05.6(6)(e)(iii) If the subsidence survey determines that no material damage or diminution <br />of reasonably foreseeable use could result in the event of subsidence predicted to occur within <br />the permit and adjacent area, and the Division concurs with that conclusion, the application
