A recently adopted law effectively bans tankers carrying liquefied natural gas from entering Narragansett Bay -- a restriction Rhode Island lawmakers hope will prevent an LNG terminal from being built in nearby Fall River, Mass. Coast Guard officials say the law may prove illegal and could seek to block it. The Boston Globe reported that the bill, signed on July 11 by Gov. Don Carcieri, prohibits LNG tankers from coming within hundreds of yards of multiple obstacles and hazards, including people, docks, waterfront facilities, hunting grounds or anywhere workers are welding. As a result, LNG tankers can't legally enter even the widest entrances to Narragansett Bay, said Rep. Raymond Gallison Jr., D-Portsmouth, the bill's sponsor.
