[6.4.21(8 and 9)] Ground Water Information <br /> The GTM is contained within a commercial grade metal building that will be <br /> constructed according to commercial building code including foundation and concrete <br /> floor design. Groundwater will not be impacted or intercepted by the GTM. <br /> [6.4.21(10 and 11)] Surface Water Information <br /> Exhibit E includes the engineered drainage plan for stormwater runoff as <br /> roadside ditches. All milling and processing will occur inside the commercial metal <br /> building. Site runoff will be limited to only that storm water during precipitation <br /> events or snow melt events. <br /> [6.4.21(12)] Water Quality Monitoring Plan <br /> The GTM is a no discharge operation therefore, a water quality monitoring <br /> plan is not provided nor is a CO Discharge Permit required. <br /> [6.4.21(13)] Climate <br /> No liquid containment systems are planned or open to the environment. <br /> [6.4.21(14)] Geochemical Data and Analysis <br /> No mining, on-site solution containment systems or facilities or disposal of <br /> material will occur on site. Feedstock material and byproducts will be stockpiled on <br /> site in concrete containment structures in limited quantities. <br /> Cynthia Parnow, geochemistry at Knight Piesold, conducted geochemical <br /> characterization of the feedstock material. The report is provided herein as Appendix <br /> D. <br /> All feedstock material brought to the mill will be hauled from the mill after <br /> processing as construction material byproduct, waste for disposal or precious metal <br /> containing concentrate. No material will be disposed of on-site neither will any <br /> material be subject to long term weathering on-site. The anticipated life of any <br /> stockpiles is a maximum of 14 days. Concentrate will be sealed in 55-gallon drums. <br /> [6.4.21(15)] Construction Schedule Information <br /> The mill and storage bins will be constructed within nine months of mill <br /> approval, weather permitting. Feedstock will not be transported to the mill until the <br /> mill and storage bin construction is completed. <br /> [6.4.21(16)] Quality Assurance and Quality Control (QAQC) <br /> Construction of the mill building, an industrial metal building, does not <br /> warrant an extraordinary QAQC program. <br /> [6.4.21(17)] Plant Growth Medium <br /> Reclamation will not require revegetation. If necessary, the grounds around <br /> the building will be graded and re-graveled in preparation for sale as a <br /> commercial/industrial property. <br /> [6.4.21(18)] Wildlife Protection <br /> Colorado Parks and Wildlife was contacted January 19, 2021 for a site visit <br /> and subsequent comments. The site visit has not been scheduled as of this <br /> application submission. It will be provided immediately upon receipt. <br /> Page 19 of 23 <br />
