periods, water drains through the piles, with the large waste marble blocks acting as a sediment trap. The <br />PH of the water runoff tends to be slightly high (basic) while Yule Creek water is more acidic, so the <br />result may be a slight improvement in the quality of Yule Creek water. <br />The quarry operation generates no acid or toxic materials. The waste generated by marble cutting is the <br />only by product of mining. Maintenance of diesel powered equipment will take place underground. <br />Generated waste oil and other fluids from maintenance will be transported offsite and disposed of in an <br />appropriate matter. Other refuse will be transported offsite and be disposed of in an approved matter. <br />Colorado Stone expects no processing on site except for marble cutting or polishing operations. Such <br />processing will occur underground and involve no process chemicals. Finished marble blocks will be <br />stored at the Storage Area (storage area) in Marble, CO prior to shipping to customers. <br />The marble to be quarried is approximately 280 to 300 feet thick (true perpendicular thickness) in the <br />vicinity of the affected area. The marble seam dips to the west at approximately 53 degree with a strike <br />of approximately North 26 degrees west <br />The primary commodity produced is dimension stone in the form of white marble blocks. These may be <br />further processed off-site, for eventual sale to large and small marble installations shops around the <br />world. There are no incidental products to be produced by the quarry. <br />Explosives will be used as part of the mine's long term operation. Most of the blasting will take place <br />underground as part of mining, but some blasting may be necessary to remove old waste marble during <br />construction of sediment control devices and roads. Since there are no structures within a % mile of the <br />mine, no damage to structures will occur as a result of blasting. <br />2. Water Information, Rights and Augmentation <br />Water used in the mine will come from underground sumps which collect water infiltration from cracks <br />in the marble and surrounding rock in the roof of the mine. This water is used for dust control and <br />marble cutting underground. Peak use of water is 30 gpm, which is primarily recycled into the sumps. <br />Yule Quarry April 10 16
