The EPA has notified certain Gowanus-area property owners in a letter that contractors installing new bulkheads in preparation of dredging will be plugging unpermitted outfall pipes that discharge into the Gowanus Canal to prevent recontamination after the Superfund cleanup is complete.
The undated letter, from EPA Assistant Regional Counsel Brian Carr to unnamed property owners, was accompanied by maps and a table indicating the locations of the outfalls that will be plugged. The letter asks the property owners to contact EPA regarding the outfalls.
