Kennecott's Eagle Mine near Marquette will not need a federal wastewater permit. The Environmental Protection Agency made its decision late Thursday. Opponents of the mine were banking on federal review of the project to look into possible contamination of groundwater and streams in the Yellow Dog Plains.
Kennecott has all necessary state permits and has begun construction at the mine site.
In the spring, Kennecott changed the design of its wastewater disposal system so that the pipes are on the surface. EPA regulates underground injection of wastewater. The treated water will still be released into the ground. Kennecott says its water discharge system is approved by the state.
