Probable Hydrologic Consequences and Cumulative Impacts Assessment <br />-Rules 2.05.6(3) and 2.07.6(2)(c) (cont'd) <br />The projected development of the McClane Canyon and Munger Canyon Mine <br />workings indicate further impact on ground and surface water in the future. <br />Munger Creek, Buniger Canyon, Stove Canyon and a portion of the East Salt <br />Creek valley floor will be undermined. Prior to issuance of a permit to mine <br />into these areas it will be necessary to determine the absence or presence <br />of AVF's in these canyons, and to predict the. effect of mining on any AVF's <br />identified. These determinations will occur in future permit applications. <br />Mining will progress into the inferred saturated zone of the coal interval. <br />The recharge area of the Cameo seam at East Salt Creek will also be <br />significantly impacted. In subsequent permits geologic and alluvial monitor- <br />ing sites will have to be established to adequately"monitor the effect of <br />mining on geologic and alluvial ground water quantity and quality. <br />After mining is completed for these operations all portals will be sealed <br />and disturbances will be backfilled, graded, topsoiled and revegetated. In <br />this reclaimed situation the hydrologic characteristics of the disturbed <br />areas will be restored to nearly pre-mining conditions. <br />The assessment of the probable cumulative impacts of all anticipated coal <br />mining in the general area on the hydrologic balance, as described in 2.05.6 <br />(3), has been made by the Division, and the operations proposed under the <br />application have been designed to prevent damage to the hydrologic balance <br />outside the proposed permit area. <br />X. Climatological Information and Air Resources-Rules 2.04.8, 2.05.9(2)(h), <br />2.05.6(1), and 9.17 <br />The appropriate information dealing with climatology and air resources at the <br />site is contained in Sections 4.6 and 4.7 of the permit application. Salt <br />Creek Mining Company has included the required climatological information for <br />Grand Junction. No site specific information is available. <br />Salt Creek Mining Company has applied with the Colorado Department of Health <br />for an emissions permit to cover all aspects of the operation. <br />The operation is in compliance with this section. <br />XI. Topsoil-Rules 2.04.9, 2.05.3(5), 2.05.4(2)(d), and 4.06 <br />Information dealing with soils resources and topsoil handling procedures can <br />be located in Sections 3.2, 3.3 and 4.4 of the permit application. The <br />Division found no problems with the baseline soils information presented in <br />the application. A problem has been noted by the Division staff with respect <br />to topsoil handling. The applicant proposes to test the soil and add the <br />appropriate fertilizers one year after seeding and planting. She applicant's <br />reason for this is that fertilization prior to seeding will encourage <br />undesirable weedy species to invade the reclaimed site. <br />The Division agrees with this contention in part. However, because Phosphorous <br />is relatively irmbile and does not readily leach into the soil, it is best to <br />
