Cultural and Historic Resources -Rule 2.04.4 and 2.05.6(41 <br />Cultural and historic resources are discussed in Section 2.04.4 of the permit application. <br />in October 1977, Centuries Reseazch, Inc. conducted a cultural resource survey of the Blue Ribbon <br />proposed mine site. The survey found the area to contain no cultural resources. The State Historical <br />Preservation Officer concluded that the Blue Ribbon Mine would not impact significant cultural <br />resources, this was again confirmed on June 12, 1997. <br />Hydrologic Balance -Rule 2.04.5. 2.04.7. 2.05.3(4), 2.05.6(3) and 4.05 <br />Groundwater information can be found in the permit document in Section 2.04.7. The locations of <br />monitoring sites can be found in Ezhibit Z. <br />A description of groundwater occurrence and mining impacts on groundwater within the permit and <br />adjacent areas can be found in the "Probable Hydrologic Consequences" section of this document <br />and the "Cumulative Hydrologic Impact Study" document for this mine area. <br />The coal outcrop of the E seam, which Blue Ribbon has mined, is about 80 to 100 feet above the <br />stream bed of Hubbard Creek. The disturbed areas and underground mine areas are upland to the <br />alluvial valley materials. The major portion of the mine workings are above the level of Hubbard <br />Creek, so the mine presently does not experience any inflows which can be directly related to water <br />flowing in Hubbard Creek. <br />The alluvium of Hubbard Creek is the only aquifer which was used within the permit and adjacent <br />areas. This aquifer supplied the water that was consumed at the Blue Ribbon Mine. This aquifer is <br />an isolated body of alluvium. Upstream and downstream of the mine, the Hubbard Creek stream <br />valley narrows and the stream flows over resistant sandstone bedrock. <br />The Rollins Sandstone is the most significant regional bedrock aquifer in the North Fork drainage <br />basin. This aquifer outcrops in a narrow steep reach along Hubbard Creek about a mile downstream <br />of the mining operation. Recharge to this aquifer is limited within the Hubbard Creek drainage. The <br />potential use of this aquifer is limited by the steep valley slopes below the mine and the aquifer's <br />limited recharge area. No groundwater from the Rollins Sandstone will appear as mine inflows <br />_ ` <br />- .:::::::~ ...,.:::~~ arc all stratigraphieally above the R: <br />Sandstone. <br />The E coal seam is not an aquifer. The mine workings are dry, except in a few areas of fracturing. <br />Surface water information can be found in Section 2.04.7 of the permit document.
