away from these structures, it seems unlikely that any damage to the structures will occur. <br />(Rule 4.20) <br />No renewable resource lands lie within the permit azea. Information provided in the <br />application indicates that the Pine Gulch drainage, which at one time was suggested to be a <br />renewable resource area, does not in fact qualify as one. These is no aquifer or rechazge <br />azea for an aquifer in the Pine Gulch area. Core hole data supplied with the original <br />application demonstrate that the bedrock section above the level of the coal is dry. The <br />survey of wells and springs in the azea of the mine has established stratigraphically lower <br />aquifers whose rechazge azeas do not include Pine Gulch. The Pine Gulch azea is also not <br />one utilized for agricultural or silvicultural production of food and fiber nor does it serve as <br />a pasture land. The confluence of Pine Gulch and Hay Gulch approximately three miles <br />downstream from the mine was determined to be an alluvial valley floor on which <br />agricultural activities aze conducted. These activities however, do not rely on the surface or <br />ground water resources originating in the Pine Gulch azea. Provisions of the proposed <br />mining plan, furthermore, will minimize any potential for mining related subsidence <br />impacts on the Pine Gulch drainage. Elongated pillazs will not be extracted during final <br />retreat. As a result, the Pine Gulch drainage azea will be assured of continued long term <br />stability. <br />XIV. Operations on Alluvial Valley Floors <br />A. The Division has determined that an alluvial valley floor exists within the affected or <br />adjacent azea. Therefore, the following fmdings are in order for the alluvial valley <br />floor known as Hay Gulch located 7 miles SW of Hesperus, Colorado. <br />There aze currently three coal mining operations located within Hay Gulch: the King <br />Coal Mine (permitted, active), the Blue Flame Coal Mine (revoked and reclaimed), and <br />the La Plata No. 1 Mine (revoked and reclaimed). All three mines aze considered in <br />the alluvial valley floor discussion. <br />Field observations by Division staffand information contained in permit applications <br />indicate that small azeas ofunconsolidated stream-]aid materials aze present in adjacent <br />drainages. However, these azeas aze not extensive enough to meet the size criteria of <br />AVFs. <br />It has been determined that Hay Gulch meets the criteria for an AVF based upon three <br />fmdings: (1) The valley contains unconsolidated stream-laid deposits; (2) The valley <br />contains sufficient water to support agricultural activities as evidenced by (a) the <br />historical use of flood irrigation in the area, and (b) the demonstrated capability of the <br />area to be flood irrigated, and (3) The valley has demonstrated sub-irrigation. <br />It should be noted that Hay Gulch does not presently contain a stream. It is thought <br />this is due to agricultural practices in the gulch that diverts naturally occurring flow <br />22 <br />
