Section 780.21 (c) Continued. <br />Rule 2.05.6(3) <br />Revised 12/3/80 <br />These calculations indicate that the acroimt of runoff in Bolton, <br />Bush, Williams and Sudduth Draws will increase after reclamation <br />by 2_7, 0_3, 1_2 and 0.4 percent, respectively. <br />Salt Load Study <br />The length of data record on water quality during the baseline <br />period eras insufficient to determine the cumulative hydrologic <br />effect of increased dissolved salt load on receiving streams in <br />the proposed permit and adjacent area. There was no discharge of <br />leachate water from the existing mine pit and no discharge from <br />the newly constructed sedimentation ponds during the baseline <br />• period, and thus no data on these discharges were available. <br />The continuing hydrologic ironitoring program will provide data <br />on salt loading from the existing and proposed operations. Due <br />to the ephemeral nature of nznoff in the proposed permit area, <br />data fran several runoff seasons, as mi ' progresses, will be <br />needed to project the amount of salt loading on Bolton, Bush, <br />Williams and Sudduth Draws. Sufficient data should be made <br />available after the spring runoff season in 1982 to perform a <br />preliminary study on salt loading. Data and results of this <br />study will be included in the annual monitoring report to be <br />sutmitted to the regulatory authority. <br />A tentative estimate of salt loading on receiving streams can <br />be made using data collected on Williams Draw during the base- <br />780-126 gggg4 <br />
