• Crusher and retaining wall <br /> The facilities generally have either 6 or 12-inch concrete foundations. As shown on <br /> Map F-1 and Map F-1 a, various structures will remain as part of the post-mine land <br /> use. Mill equipment will be removed and repurposed or sold upon final reclamation. <br /> As noted in TR-14 and TR-15, process water and mill reagents will be drained from <br /> tanks and piping prior to dismantling the structures. The intent is for mill reagents to <br /> be used in the process. Remaining reagent and other chemicals, if any, will be either <br /> returned to the manufacturer or characterized and properly disposed of in accordance <br /> with waste disposal regulations. Should process tanks and piping require <br /> detoxification, OSMI anticipates the volume of water to rinse the system to be <br /> 10,000 to 40,000 gallons. Rinse water will be contained, characterized and disposed <br /> of in accordance with application regulatory requirements. <br /> A list of buildings / structures that will remain on site is provided in Table L-2 as part <br /> of Exhibit L. Buildings also are shown on Map F-1 and Map F-la. <br /> 3.4 Portal Areas <br /> There are three portal areas that will be reclaimed: the underground shop, the mill, and <br /> the Revenue tunnel portal. The reclamation of each portal will proceed in the <br /> following manner: <br /> Exhibit E Reclamation Plan E-6 <br /> Amendment 02 <br /> December 2021 <br />
