General Electric has agreed to continue the cleanup of the Hudson River under new, tighter federal requirements, including a limit on how much contamination could be sealed on the riverbed rather than removed.
The Environmental Protection Agency issued new requirements last week for a second phase of the cleanup, which is intended to remove PCBs, or polychlorinated biphenyls, discharged by two G.E. factories into the river over a 30-year period ending in 1977. The company carried out the first phase, along a six-mile stretch of the Hudson, from May to November of last year.
