BROOKSVILLE — The U.S. Environmental Protection Agency is getting ready to begin the clean up of an abandoned Maine mine that has left a legacy of toxic contamination.

The $3 million in Superfund money will begin a cleanup at the former Callahan Mine site in Brooksville.

During the 1960s and 1970s Callahan Mining removed an estimated 800,000 tons of rock containing copper, zinc, lead and traces of silver in an open pit mine.

The cleanup plan calls for the removal of toxic PCBs and the lead- and arsenic-contaminated soils. Contaminated materials will be disposed of in the former mine pit. A cap will then be placed over the tailings.

The Bangor Daily News says work is expected to begin next spring or summer.
