Portal Reclamation Steps <br /> Underground Storage Room Remove steel doors or leave in place <br /> Backfill with demolition debris and waste rock into <br /> tunnel <br /> Regrade backfill slope to 21-1:1 V <br /> Mill Remove steel doors or leave in place <br /> Backfill with demolition debris and waste rock into <br /> tunnel <br /> Regrade backfill slope to 21-1:1 V and revegetate <br /> Revenue Install steel bat gate on portal <br /> Backfilling will be conducted via dozer to the surface highwall. No bat survey has <br /> been conducted in this area and no bats have been observed in the existing Revenue <br /> Tunnel, however, the Division of Parks and Wildlife (DPW) stated that the installation <br /> of a bat gate at this portal was acceptable in their comment letter on the original permit <br /> application. <br /> 3.5 Backfill Ponds and Collection Ditches <br /> Sediment Pond #1 will remain in place as a sediment control feature during <br /> reclamation of the Atlas TSF. The mine water ponds # 1, 2, and 3 will remain after <br /> reclamation, as shown on Map F-1. These features will not be backfilled or regraded <br /> as they were constructed to blend in with the existing contours at the site. Mine water <br /> will continue to be delivered by gravity in HDPE pipes to the mine water pond and the <br /> water will flow into Ponds 2 and 3 for passive treatment prior to discharge to Sneffels <br /> Creek(TR-10) via Outfall 002A as part of CDPS Permit CO-0000003. Map F-1 <br /> shows the remaining earthworks, which are previously disturbed areas composed of <br /> waste rock from previous mining operations, for each pond. The collection ditches <br /> surrounding Waste Piles will remain to divert water from the Waste Piles. Other <br /> collection ditches will be removed once the revegetation of disturbed mine areas is <br /> successful. <br /> Exhibit E Reclamation Plan E-7 <br /> Amendment 02 <br /> December 2021 <br />
