Berkeley Pit Timeline

The timeline reflects recent project changes agreed to in the Berkeley Pit/Mine Flooding Consent Decree approved by
the federal court in August 2002. The milestone dates assume that the Horseshoe Bend treatment plant will start operating in December 2003.

It should be noted that earlier timelines called for a technology review around 2006-07. However, since a treatment facility for Horseshoe Bend water will be built already, and that same facility will eventually be used to treat Berkeley Pit water, the EPA has eliminated the need to evaluate treatment technologies. Check back for future timeline adjustments.
