Atlantic Richfield, EPA Agree on Butte Silver Bow Cleanup

By Tripp Baltz

BP PLC subsidiary Atlantic Richfield Co., the Environmental Protection Agency, and other parties have agreed on a plan to clean up contaminated soil, groundwater, and surface water laced with heavy metals in Butte, Mont.

The Jan. 26 preliminary agreement, the focus of a federal consent decree being negotiated with the parties by the Justice Department, outlines future cleanup work at the Silver Bow Creek Butte Area Superfund Site polluted by historic mining activity.

The site is one of 21 high-priority contaminated areas targeted by EPA Administrator Scott Pruitt for immediate and intense attention (see related story).

The parties include Atlantic Richfield, Montana, the city of Butte Silver Bow, and Justice Department. The EPA said it will begin working with the parties immediately to develop a proposal to amend an existing cleanup plan.
