Federal Lands 35.7 35.7 <br /> Affected Land 4,117 4,360.2 <br /> Approval of the changes proposed in AM-07 will amend Henderson acreages by adding a net total <br /> of 243.2 acres to the Affected Land area as follows: <br /> • 21.9 acres: URAD Wastewater Treatment Plant; <br /> • 9.8 acres: Water conveyance pipeline between the Mine and URAD and proposed potential <br /> URAD Wastewater Treatment Plant discharge relocation; <br /> • 11.3 acres: Mine Site addition; <br /> • 151.9 acres: Subsidence area; and <br /> • 48.3 acres: Mine Site reconciliation. <br /> Of the total affected land, 3,996 current acres are located at the Mill site which is not affected by <br /> the proposed changes. <br /> 3.0 RECLAMATION PLAN FOR ADDITION OF AFFECTED LAND <br /> For the purposes of this Amendment, the increase in affected lands does not alter the existing <br /> reclamation plan for the Mine or Mill, and no new disturbance will take place. The acreage being <br /> added under this Amendment will be reclaimed as follows: <br /> • URAD Wastewater Treatment Plant and the water conveyance pipeline between the Mine <br /> and the Treatment Plant will continue to be operated post-mine closure, thus reclamation <br /> of the pipeline and Treatment Plant is not being considered with this Amendment. <br /> • Any disturbance to the 50-foot east-west buffer area along the northern edge of the current <br /> affected lands boundary would be reclaimed in the same fashion as immediately adjacent <br /> lands. <br /> • Subsidence associated with mining activity will remain. Adequate signage will be installed <br /> to indicate hazards and prohibit the public from accessing the area. <br /> 4.0 WILDLIFE INFORMATION <br /> The addition of affected lands under this Amendment does not alter other elements of the <br /> previously submitted wildlife information. <br /> Henderson recognizes the following as a Colorado State-listed endangered species which occur on <br /> property, but outside of the current and proposed affected land boundary: <br /> Species Location Est.
