be tested for pH as it leaves the dewatering screen. Water with pH lower than 6 and <br /> higher than 8.5 will be diverted to a holding tank where it will be neutralized prior to <br /> returning to the water circuit. <br /> The applicant will rely on a municipal water source, specifically the City of <br /> Idaho Springs, CO. Ms. Wonder Martell of the City of Idaho Springs executed the <br /> account documents on January 26, 2021 and are provided herein. <br /> The GTM is not a mining operation. Groundwater will not be encountered, <br /> intercepted or impacted. The mill will not discharge process water, thus not <br /> impacting the nearby surface water Clear Creek. Storm water will be managed with <br /> road side ditches or collection sumps from mill structures. Stormwater run-off from <br /> the interior road will be conveyed off-site via roadside ditches. Stormwater run-off <br /> from structures will be directed to the sumps and pumped into the process water <br /> system. <br /> The mill's objective is zero waste. GTM's products will be appropriate for <br /> beneficial end uses. Feedstock and byproducts will be characterized by TCLP for <br /> hazardous waste determination and then tested against construction material <br /> standards for suitability for use in the construction industry. Included as Appendix A <br /> is a Letter of Intent from Mountain Property Builders to accept the mill fines. Only <br /> feedstock that passes TCLP test will be accepted for processing. No process water <br /> impoundments, stockpiles or tailings impoundments are planned for on-site waste <br /> storage. <br /> GTM will impact the hydrologic balance as historic precipitation that is <br /> managed through engineered drainage structures, roadside ditches, and sumps. <br /> Storm water will discharge at historic rates, preventing off-site damage. The future <br /> land use is industrial/commercial that will manifest as a building and two loading <br /> areas with appropriately engineered drainage system. <br /> Explosives will not be used during milling or reclamation. <br /> Page 6 of 21 <br />
