• Although the materiels present et the Keenesburg mine ash disposal <br />site have relatively low strengths associated with them, these <br />materiels will not be required to meet engineering criteria <br />regarding slope stability and subsidence. <br />The proposed ash disposal site boundary is located on wind-blown <br />sand deposits. Within the ash disposal site boundary there are no <br />streams of any }rind. The permeability of the blow sand is evidently <br />sufficient to prevent overland runoff. There is no evidence of <br />channels or even rills that would be indicative of surface runoff. <br />The absence of any streams or channels within the life-of-mine <br />boundary is taken to mean that no lands within that boundary qualify <br />as alluvial valley floors or flood plains. The proposed area is not <br />shown to to exist in any flood plain zone by the Weld County <br />Plnnninq Department. <br />The proposed ash disposal area is not located within any Weld County <br />Airport overlay district. <br />Water Supply <br />Coors does not anticipate that any water will be used for <br />construction purposes. Fugitive dust, if any, will be controlled by <br />covering the ash with overburden. Coors does have two appropriated <br />Laramie-FoxHills aquifer wells and pit water sumps which could be <br />used if necessary. Water well permits and completion reports are <br />• included in Appendix ~. <br />kight of Entry <br />Presented xn Appendix C are copies of the documents of conveyance <br />granting Adolph Coors Company the right to extract coal by surface <br />mining methods in such instance where the private mineral estate is <br />served from the private surface estate. Also included is a copy of <br />a General Conveyance, Assignment and Transfer document to Coors <br />Energy Company from Adolph Coors Company. <br />Noise <br />The Keenesburg Mine is considerably removed from any town, city or <br />inhabited dwelling that would be affected by adverse noise produced <br />by ash disposal activities. <br />Soils Investigation <br />A Soil and Vegetation Inventory keport is presented in Appendix D. <br />Surface/Subsurface Owners <br />A certified list o£ the names, addresses and corresponding parcel <br />identification number assigned by the Weld County Assessor are <br />• presented in Appendix E. Documents conveying surface end mineral <br />rights to Adolph Coors Company/Coors Energy Company are found i~n <br />Appendix C. <br />-7- <br />
