ALBANY — The U.S. Environmental Protection Agency said 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 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.

On Wednesday, Gov. Andrew Cuomo released the following statement

"Based on extensive data, it is overwhelmingly clear that GE's cleanup of PCB contamination is not complete. The EPA made the right decision by heeding our warnings and not issuing a certificate of completion this past month.

"As I have said before, if the EPA reverses course and chooses to ignore the facts, we will partner with New York's Attorney General to sue the federal government. The health and wellbeing of New Yorkers is at stake, and we will not rest until the cleanup is completed once and for all."

The U.S. Fish and Wildlife issues a letter to the EPA last week expressing concerns about the significant PCB contamination left in the Hudson River.
