Dredging of the upper-Hudson River is expected to resume Wednesday.
The U.S. Environmental Protection says Monday that the fifth season of dredging for PCBs by General Electric will be spread out over 30 miles of the river north of Albany.
The Fairfield, Connecticut-based company agreed with the EPA to remove PCBs from a 40-mile stretch of river at a cost regulators estimate will be about $2 billion. Until 1977, GE discharged into the river about 1.3 million pounds of PCBs, which were used as coolants in electrical equipment.
Dredging is expected to be complete as early as 2015, with an additional year of habitat planting and reconstruction.
The federal Superfund project began in 2009. It targets approximately 2.65 million cubic yards of PCB-contaminated sediment. About 70 percent has been removed.
