GLENROCK, Wyo. (AP) — The state of Wyoming is recognizing the reclamation efforts done at the Dave Johnston coal mine in Converse County.
The Wyoming Department of Environmental Quality says the mine has received the 2012 State of Wyoming Reclamation Award.
The coal mine operated from 1958 until September 2000. About 104 million tons of coal were mined during that time, disturbing about 4,800 acres.
The coal was used to generate electricity at PacifiCorp's nearby Dave Johnston Power Plant.
Reclamation since the mine closed included backfilling of existing highwalls, innovative seeding of plants and shrubs and construction of 6 man-made springs to support the restored ecosystem.
In addition, 158 wind turbines have been installed on the old mine site.
