MANAGEMENT <br /> Supplemental Information <br /> Surface and Groundwater impact analysis: <br /> Surface water monitoring point SW-06 is located downstream of the West Mine. <br /> Review of the SW-06 data which is submitted as part of the Bowie No.1 Annual <br /> Hydrologic Review shows that there has not been a negative impact on the waters of <br /> East Roatcap creek, and the average values for laboratory parameters do not show any <br /> negative water quality trends. Further, approval of TR-58 documented that drainage <br /> from the reclaimed West Mine area does not contribute suspended solids to streamflow <br /> or runoff outside the permit area in excess of pre-mining levels. <br /> There are no nearby groundwater monitoring points upstream or downstream of the <br /> West Mine from which to analyze data. However, since data for SW-06 shows no <br /> negative impacts to surface waters, it would lead to the conclusion that no negative <br /> impacts to the groundwater resources would be seen. <br /> Post Mining Land Use <br /> The Post Mining Land Use of the West Mine area is livestock grazing as well as deer <br /> and elk winter habitat. This designation is consistent with the historical land use of the <br /> area and the management plans of the Bureau of Land Management. <br /> Review of collected data demonstrates success and utility of the vegetated areas <br /> especially given the vegetative ground cover and favorable results with regard to <br /> diversity and production despite wildlife grazing. The 2019 and 2021 vegetation reports <br /> indicate the ground cover of perennial plants within the reclaimed areas are comparable <br /> to adjacent undisturbed native communities and plant succession is occurring and <br /> progressing in a positive direction, indicating that plants are self-sustaining. This <br /> demonstrates the success and utility of the vegetated areas to be used for the approved <br /> post mining land use of livestock grazing and deer and elk winter habitat. <br />
