. This was the only coal slurry operation in the country and only plant that used groundwater in such a way.

The Black Mesa Mine's last day of operation was December 31, 2005. One of the power plants served by the coal mined at the location had the highest emission levels in the Western United States.

The Office of Surface Mining approved Peabody's permit request to continue operations at the mine on 22 December 2008. However, in January 2010, an administrative law judge, on appeal of that approval, decided that the Final EIS did not satisfy the National Environmental Policy Act because it did not take into account changed conditions, and vacated the approval.
