ALBANY, N.Y. (AP) — The U.S. Environmental Protection Agency says it needs to finish a review of a $1.7 billion Superfund cleanup of the Hudson River before declaring whether the job was completed properly.

The EPA told General Electric Co. in a letter Tuesday it expects to finalize its review early this year. Boston-based GE asked for a "certificate of completion" a year ago and the agency was obliged to respond by Wednesday.

GE completed removal of 2.75 million cubic yards (2.1 million cubic meters) of polychlorinated biphenyl-contaminated sediment from the river in 2015.

The EPA has said that, based on existing data, it does not appear as though more dredging is needed.

New York state officials and other critics pushing for a broader cleanup say too much PCB-contaminated sediment remains in the river.
