Don’t dump dredge spoil in eastern Long Island Sound.
That was the message some speakers had for the federal Environmental Protection Agency Wednesday at a hearing on finding potential sites to replace two existing dredge disposal sites in eastern Long Island Sound.
Others argued that dredging is necessary to maintain a water-based economy.
The meeting, held at Suffolk County Community College’s culinary center in Riverhead, was billed as a “notice of intent to prepare a Supplemental Environmental Impact Statement to evaluate the potential designation of one or more ocean-dredged material disposal sites to serve the eastern Long Island Sound region.”
There are four such dredge dumping sites in Long Island Sound now, one dubbed the Western Suffolk site, south of Stamford, Conn.; one called Central Long Island Sound, south of New Haven; one called Cornfield Shoals, north of Greenport; and one called the New London site, just west of Fishers Island.
The Cornfield Shoals and New London sites are scheduled to be closed on Dec. 23, 2016, and the EPA is looking for new sites for dredge disposal, which was the subject of the hearing.
Most of what is disposed in these sites comes from Connecticut, according to the EPA. That’s because the dredge material from Long Island is mostly sand, and can be used for beach restoration, whereas most of the dredge material from Connecticut is fine-grained silt or clay and cannot be used for beach restoration.
The Farmingdale-based Citizens Campaign for the Environment doesn’t think any dredge spoil should be dumped in Long Island Sound, according to the non-profit group’s executive programs manager, Maureen Dolan Murphy.
That group opposed the designation of the two western Long Island Sound sites in 2004 and opposes designating new sites, as well.
“It did not make logical sense that after millions of dollars spent on restoring the Sound, we would designate it as a long-term dumping ground,” she said.
She said CCE agrees that dredging for navigation safety is necessary, but that open water disposal for dredge materials is not.
She said EPA and the U.S. Army Corps of Engineers in 2005 agreed to phase out open water dumping and to develop a “Dredged Material Management Plan” before deciding on its next step.
But that plan has never been developed, Ms. Murphy said.
“CCE believes it is risky and ill-advised to proceed with a long-term designation of an open-water disposal site before the final development of a DMMP,” she said. “Particularly since the goal and intent of the DMMP was to reduce open water disposal.”
Southold Town Councilman Al Krupski, who is running for Suffolk County Legislature in a special election being held Tuesday, echoed those sentiments.
“If Long Island Sound is a federally designated estuary, how do we propose to use it as a dump site for toxic spoil?” he said. “It just doesn’t’ make any sense.”
The Fishers Island Conservancy also objects to any further open water dumping sites in Long Island Sound, and feels EPA should look to areas outside of Long Island Sound and Block Island Sound for dump sites, according to Robert Evans of the FIC.
“We’ve been concerned for many years about the damage caused by the large-scale disposal at the New London site,” Mr. Evans said. “The Conservancy was party to the 1995 lawsuit that resulted in a 2002 settlement providing for the EPA’s formal designation process for dredged material disposal sites.”
He said the last large-scale dumping in the New London site was seven years ago, when about 400,000 cubic yards of dredge material was dumped there.
“The lobster population was greatly harmed and few believe the damage was coincidental,” Mr. Evans said, adding that the waters near the site have very strong currents and shallow depths.
“Dumping spoil in those waters is akin to throwing dirt into a fan,” Mr. Evans said.
Daniel Natchez, who owns a Mamaroneck-based environmental waterfront design company, took the opposite side of the argument, saying that people need to consider the economic impacts of not dredging.
“If you don’t dredge, the material that everyone is concerned about just sits there, and you swim in it, or have recreation in it,” he said, adding that people won’t have access to waterways.
“These are things that are going to have an adverse effect to quality of life,” he said.
And Bill Spicer, who owns Spicer’s Marina in Noack, CT, near Mystic, also feels that dredging is needed for the economy.
“Connecticut has billions of dollars at stake on the waterfront,” he said.
He suggested the dredge disposal sites be put in Connecticut waters, since Connecticut uses them more often.
