MASSENA (AP) - The U.S. Environmental Protection Agency has proposed a plan to clean up Grasse River sediment polluted by an Alcoa aluminum plant near New York's northern border.
The plan announced Monday calls for dredging a 7.2-mile stretch of the river where sediment is contaminated with polychlorinated biphenyls, or PCBs. About 109,000 cubic yards of polluted sediment would be dredged and replaced by clean material. Areas in the main channel would be capped with sand and rock to prevent pollution from moving.
Alcoa is paying for the $243 million cleanup with EPA oversight.
Public hearings are planned at the St. Regis Mohawk Reservation Oct. 29 and in Massena Oct. 30.
EPA has details of the Superfund site and public hearings on its website at 1.usa.gov/SUcU0F.
