New York state has filed a lawsuit against the U.S. Environmental Protection Agency opposing a plan to allow dredged sediments to be dumped into the Long Island Sound.

Gov. Andrew Cuomo has threatened for more than a year to take the action announced Thursday. He and fellow Democrat Attorney General Eric Schneiderman say the EPA plan will allow tens of millions of cubic yards of dredged sediments to be dumped in the waterway that divides Long Island and Connecticut.

Connecticut’s congressional delegation has endorsed a 30-year U.S. Army Corps of Engineers plan for dredging around Long Island Sound. Some lawmakers in New York are opposed to that plan.

Connecticut's environmental commissioner, Rob Klee, has endorsed a U.S. Army Corps of Engineers plan to continue dumping dredged materials into areas of Long Island Sound. Those materials, like silt, are dredged by the corps from Connecticut waterways to keep them navigable.

Along with dumping some of the dredged materials into the Sound, the 30-year draft plan also suggests other ways to get rid of it, like recycling the dredged materials, and using it to fortify beaches, or restore marshes.
