Coast Guard escorting an LNG tanker last summer.

Dan Hill, who lives near Boston Harbor and is running for state senate in a district that includes Chelsea and Everett, says the state should do everything it can to try to keep LNG tankers out of Boston Harbor - especially Yemeni ones - and phase out the Distrigas natural-gas terminal in Everett in favor of a new facility in Naragansett Bay:

Hill noted that for new LNG ports the Coast Guard requires "security zones" restricting movement within 1,000 yards on either side of an LNG tanker, a standard that could not possibly be met in Boston Harbor. "I find it disturbing that safety requirements for new facilities apparently do not need to be met for existing facilities."
