CARTERET - The office of New York's attorney general is expressing serious concerns about a large-scale environmental project in Middlesex County that's been the subject of an ongoing Kane In Your Corner investigation. In a letter obtained exclusively by News 12 New Jersey, the office urges both the Federal Environmental Protection Agency and the New Jersey Department of Environmental Protection to take a closer look at the Rahway Arch project, which received final approvals last month. The letter also urges them to publicly release all research related to it.

The Rahway Arch property is one of New Jersey's most contaminated sites. Once home to an American Cyanamid plant, it is filled with acres of cyanide-tainted sludge. But it's the location, right on the Rahway River, that has people so concerned. As Kane In Your Corner has been reporting since last year, even some of the NJDEP's own scientists worry that the state-approved plan to cap the site with tons of soil and concrete could force cyanide into the river.

That didn't stop the Christie administration from pushing the project through. Memos obtained by Kane In Your Corner show NJDEP staff referring to it as "an upper management priority," and the company doing the cleanup work, Soil Safe, has close ties to several influential New Jersey politicians.

Soil Safe has repeatedly claimed it has research that proves the project is safe, but it has refused to make that research public. In its letter, the New York Attorney General's Office urges both the NJDEP and EPA to release it, arguing that "without full disclosure, the public cannot be assured that all appropriate actions to protect the environment and public health are being taken."

It's unclear whether this belated effort by the New York attorney general will make any difference. New Jersey officially gave the final permits to the Rahway Arch project last month, and work is already underway.
