New York conservation officials say Atlantic Richfield Co. has agreed to clean up PCB-contaminated soils and Hudson River sediment in Westchester County in a project estimated to cost more than $250 million.
The Department of Environmental Conservation says the consent order with ARCO is for the Harbor at Hastings site where its predecessor company, Anaconda Wire & Cable Co., released polychlorinated biphenyls and metals into the soil, groundwater and river sediment from manufacturing operations.
DEC Commissioner Joe Martens says Tuesday it's an important step in restoring the health of the Hudson.
The remedy calls for first containing the liquid PCBs, dredging, excavating contaminated soil, backfilling and covering the site with soil while protecting adjacent areas.
The company didn't initially reply to a request for comment.
