6.3.2 Exhibit B Site Description The GTM will be constructed and operated on the historic disturbance of the Golden Nugget, Donna Juanita & Gladstone mines, south of I-70 and Clear Creek. The soils in the approximate two-acre mill area are rock outcrop, gravelly sandy loam and Bend emeere-Tolland complex. The NRCS web soil survey and soil series descriptions are provided in herein. Permanent man-made structures within 200 ft. of the affected area include an Xcel Energy electricity distribution poles and gas line, Stanley Road a CO DOT highway, buildings owned by David Mosch and buildings owned by Harold Lesser. These structures are identified on Exhibit E and structure agreements are provided in Exhibit L. The Clear Creek streambed lies north of Stanley Road, north of the mill site. GTM is designed with a recirculating process water system. The wet processing component will be enclosed in a metal building. Mill process water will not be discharged from the site. Storm water will be conveyed from the site by way of the roadside ditches. The ditches will converge with the culvert and drainage system of Stanley Road. Storage material bins will be constructed as concrete blocks on three sides and a concrete floor with a 2% slope to the center to contain stormwater. Each storage bin will be fitted with a tarp the covers the entire bin contents and secures to the outside of the containment structure to prevent precipitation from falling directly on stored material. De minims precipitation that might become detained within the two concrete containment structures for feedstock and by product materials will be released within 72 hours into the roadside ditches. Mr. Mark Lamb and Mr. Joseph Walter of CO Department of Parks and Wildlife were sent the draft site plan and mill description on January 19, 2021. A site visit is anticipated but not scheduled at the time of this application. Page 4 of 23
