cal, and other surface and underground equipment. <br />• 9.3.3.2.5 Electrical Distribution Center <br />This facility is a fenced and locked area and houses the electrical <br />equipment necessary to receive and distribute the electrical power <br />for the operation. Electrical supply will be from the Public <br />Service Company of Colorado. <br />9.3.3.2.6 Water and Sewage Treatment <br />There will be two 10,000 gallon holding tanks for the collection of <br />grey water and septic wastes. The septic waste will be <br />periodically pumped by a commerical disposal contractor and <br />transported to an existing county-approved treatment system. The <br />grey water will be used to irrigate the landscaped areas during the <br />growing season and added to the mine water (less than .09% of total <br />volume) during the winter months. <br />9.3.3.3 water System <br />NCIG will require nearly 300 acre-feet annually of make-up water in <br />the hydraulic mining circuit, assuming a production rate of 1 <br />million tons per year. This make-up water will be utilized to <br />recharge the closed water circuit when natural losses occur through <br />evaporation, adhesion and seepage. when operating at 1,000,000 <br />tons per year of clean coal, approximately 9000 gpm will pass the <br />mine portal. This water will be carried underground in high and <br />low pressure pipe to the working faces where it will be utilized to <br />break the coal in hydraulic production stopes and to transport the <br />Coal to the surface in open flumes. <br />The amounts of water required to transport the coal will vary <br />depending on the size and quantity of coal produced. Once the coal <br />reaches the surface, the coarse coal will be separated from the <br />. NCIG - Coal Ridge #1 4-29 ABC/1145/910509 <br /> <br />
