The Times Union is reporting the U.S. Environmental Protection Agency has agreed to review the Hudson River PCB tests conducted by the state last year in advance of ruling whether the $1.7 billion, seven-year dredging project was a success. Concerned that too many PCBs were left behind, the state is pushing the EPA to require further dredging. In the summer of 2017, the state Department of Environmental Conservation gathered and analyzed approximately 1,800 samples from the river and submitted the results to the EPA. "While EPA, its partners, and the public continue to give serious attention to the post-dredging recovery of the Upper Hudson, it's imperative that we also expand the scope of the Agency's efforts to ensure the Hudson River is fully remediated," said EPA Regional Administrator Pete Lopez. Lopez wrote that EPA expects to "collaborate with the state in order to make joint findings and conclusions about the (state) data." Lopez also said the federal agency is now positioning itself to assess the portion of the river between Albany and New York City. Read the full story in the Times Union.
