demonstration by a qualified professional engineer that the resulting sediment pond <br /> will be as environmentally sound and structurally stable taking into consideration <br /> physical, climatological and other characteristics of the site (4.05.6(11)). <br /> E. Acid-forming and Toxic-forming Spoil <br /> Based upon information provided by GCC, the Division does not anticipate <br /> that any acid-forming or toxic-forming spoil will be encountered during the <br /> operation of the King Coal Mine (4.05.8(3)). <br /> F. Impoundments <br /> With the exception of sedimentation ponds (discussed above), the applicant has not <br /> proposed the design and construction of impoundments for the King Coal Mine <br /> (4.05.9). <br /> G. Surface and Ground Water Monitoring <br /> 1. GCC will conduct monitoring of ground water in a manner approved by the <br /> Division. Under the current plan (since TR-26), ground water is monitored <br /> in four wells in the Hay Gulch alluvium: MW-HGA-4, which is upgradient <br /> of King I; the Wiltse Well (near the King I entrance); a well upgradient of <br /> King II and downgradient of King I; and a well downgradient of King II. <br /> With TR-26 (issued November 2, 2016), four bedrock monitoring "clusters" <br /> were added to the monitoring plan. Each cluster contains three wells: a <br /> well in the Cliff House formation, a well in the "A" coal seam, and a well <br /> in the interburden below the "A" seam. (4.05.13(1)). <br /> 2. GCC will conduct monitoring of surface water in a manner approved by the <br /> Division. Surface water monitoring includes NPDES discharges at the <br /> three ponds (which rarely, if ever, discharge) and at upstream and <br /> downstream locations on Hay Gulch Ditch. <br /> H. Transfer of Wells <br /> At the conclusion of mining, the two wells used in the operation will be <br /> transferred back to the owners at the written request of the surface owners <br /> (4.05.14). <br /> I. Discharge of Water into an Underground Mine <br /> There will be no diversion of water from a surface or underground mine into <br /> underground mine workings (4.05.15). <br /> J. Stream Buffer Zones <br /> 16 <br />
