EXHIBIT G: WATER INFORMATION <br />The site lies in a high altitude mountainous environment. Most surface water issues are associated <br />with springs melts and occasional short high intensity storm events. Water handling at the site has <br />been designed to address these issues. Prevention of significant run on water is prevented by the <br />ridge which lies to the west of the Jefferson Quarry, Jefferson WRL, Lincoln Gallery, Washington <br />Gallery, and Washington WRL. The Franklin Quarry is isolated by a natural drainage during Phase <br />1 and a diversion ditch which will be installed prior to activities within Phase 2. <br />The surrounding area drains exclusively into Yule Creek. Yule Creek joins the Crystal River near the <br />town of Marble approximately 2.5 miles north of the quarry. The closest standing water is located at <br />beaver ponds approximately 1 mile north of the quarry. In the area near the quarry, Yule Creek is a <br />rapidly falling high mountain stream. It drops approximately 600 feet from the southern end of the <br />New Discovery claim to the northern end of the White Marble claim. Based on the drainage area, <br />Yule Creek, where it joins the Crystal River at Marble, is estimated to have a mean flow of 42 and <br />76 cubic feet per second during May and June respectively. <br />All activities west of Yule Creek excluding the Washington WRL have been designed to drain into <br />the Washington Gallery. The interior road ditch channels water into the Utility Tunnel, near the <br />generators. Windrows occur on the outside edge of all pads and roads to ensure water is kept on the <br />disturbed areas and allowed to flow into the drainage ditches. Water is allowed to settle and infiltrate <br />into the fault system. It is not anticipated that water will overflow the Washington Gallery. The site <br />does have an active discharge permit, as it does not discharge. If discharge seems likely, an overflow <br />pipe would be installed into Portal #4 to allow for discharge of the Washington Gallery into Yule <br />Creek. The quality of the water in the mine sumps has been monitored periodically by the Colorado <br />Department of Health. Records indicate no water quality problems and none are expected in the <br />future. The quarry previously operated under Permit No. CO -G-500184 issued by the Colorado <br />Department of Health. Prior to Colorado Stone Quarries ownership the quarry was also operated <br />under a new Process Water and Stormwater permit from that CDPHE. The maximum flow from the <br />quarry is estimated at 100 gpm (0.16 cfs) during the high flow season, so there should be no noticeable <br />impact on Yule Creek from such discharge. A discharge point has been shown on the enclosed maps. <br />The Pride of America DRMS 112c <br />Exhibit G - 1 12/23/15 <br />
