(c) Water Resources: The affected area drains exclusively into Yule Creek. Yule <br /> Creek joins the Crystal River near the town of Marble approximately 2.5 miles north of the <br /> quarry. The closest standing water is located at beaver ponds approximately 1 mile north of the <br /> quarry. In the area near the quarry, Yule Creek is a rapidly falling high mountain stream. It <br /> drops approximately 600 feet from the southern end of the New Discovery claim to the northern <br /> end of the White Marble claim. Based on the drainage area, Yule Creek, where it joins the <br /> Crystal River at Marble, is estimated to have a mean flow of 42 and 76 cubic feet per second <br /> during May and June respectively. <br /> The underground portions of the quarry receive water from faults in the marble, primarily <br /> in early summer. This water is generally retained within the settling sumps in the quarry. But <br /> during high runoff periods, some water discharge will be pumped from the sumps. The quality <br /> of the water in the sumps has been monitored periodically by the Colorado Department of <br /> Health. Records indicate no water quality problems and none are expected in the future. CYMC <br /> operated the quarry under Permit No. CO-G-500184 issued by the Colorado Department of <br /> Health. Sierra Minerals Corporation is applying for a new Process Water and Stormwater permit <br /> from that agency. The maximum flow from the quarry is estimated at 100 gpm(0.4 cfs) during <br /> the high flow season, so there should be no noticeable impact on Yule Creek from such <br /> discharge. <br /> (d) Wildlife: Based on recent contact with the Colorado Division of Wildlife, there are <br /> no critical or important wildlife habitats or wildlife species that will be impacted by the proposed <br /> operation. A letter from the Division to that effect is attached. <br /> 13 <br />
