Water Balance <br />A water balance study has been prepared by CDS Environmental <br />Services LLC and is included in this submission as Appendix 4(11). All <br />water entering the mine is purchased at considerable cost; water is not <br />left to "pond". All water is used in the mine for the sole purpose of <br />controlling respirable dust as per MSHA regulations. Water is sprayed <br />on the coal as it is being cut with continuous miners. This coal is <br />shipped to the surface immediately via conveyor belts. MSHA regulations <br />forbid storage of cut coal inside the mine. Water is sprayed on the <br />conveyor belts to suppress dust. This water evaporates continuously <br />and is sprayed continuously to keep the belts damp. Water is sprayed on <br />the roadways to control dust that would be stirred up by mining <br />machinery. Due to the large quantity of and Southwest Colorado air that <br />is forced into the mine to ventilate the working areas, as per MSHA <br />regulations, water applied to the roadways evaporates quickly and must <br />be re-applied frequently <br />GCC Energy, LLC King II Mine <br />Section 2.05.3 <br />Page 8 July 11, 2017 (RN -07) <br />
