Supplemental Information
Surface and Groundwater impact analysis:
CIVIL ENGINEERING
CONST. MANAGEMENT
Surface water monitoring point SW-05 is located near toe of the ROM area. Review of
the SW-05 data which is submitted as part of the Bowie No.1 Annual Hydrologic Review
shows that there has not been a negative impact on the waters of East Roatcap creek,
and the average values for laboratory parameters do not show any negative water
quality trends. Further, approval of TR-58 documented that drainage from the
reclaimed ROM does not contribute suspended solids to streamflow or runoff outside
the permit area in excess of pre -mining levels.
There are no nearby groundwater monitoring points upstream or downstream of the
ROM from which to analyze data. However, since data for SW-05 shows no negative
impacts to surface waters, it would lead to the conclusion that no negative impacts to
the groundwater resources would be seen.
Post Mining Land Use
The Post Mining Land Use of the ROM area is livestock grazing as well as deer and elk
winter habitat. This designation is consistent with the historical land use of the area and
the management plans of the Bureau of Land Management.
Review of collected data demonstrates success and utility of the vegetated areas
especially given the vegetative ground cover and favorable results with regard to
diversity and production despite wildlife grazing. The 2019 and 2020 vegetation reports
indicate the ground cover of perennial plants within the reclaimed areas are comparable
to adjacent undisturbed native communities and plant succession is occurring and
progressing in a positive direction, indicating that plants are self-sustaining. This
demonstrates the success and utility of the vegetated areas to be used for the approved
post mining land use of livestock grazing and deer and elk winter habitat.
