PORTLAND, Ore. (AP) -- Oregon environmental regulators have reached a deal with Owens-Brockway Glass Container on a partial cleanup of Johnson Lake along the Columbia River near Interstate 205.

The plan calls for the company to spend $1.3 million to address two hot spots of lake sediment contaminated with high levels of PCBs.

The chemical was used in electrical insulators but is now banned because of links to cancer.

Owens-Brockway has manufactured glass at its plant on the lake's south side since 1956. It will dredge 7,500 cubic yards of contaminated sediment, then store, cap and monitor the contaminated soil.

The 18-acre lake connects to the Whitaker Slough, which feeds into the Columbia Slough.
