The House of Representatives on May 10 joined a growing list of official bodies erecting hurdles in front of a proposed liquefied natural gas terminal in Fall River, Mass. The House unanimously approved legislation that would, in effect, block LNG tankers from sailing through Rhode Island waters to get to the terminal. Sponsored by Rep. Raymond E. Gallison Jr., D-Bristol, the bill would prevent any tanker from coming within 1,000 yards of any residences, piers, docks, wharves or waterfront facilities. A tanker sailing to Fall River would have to pass within 600 yards of Fort Wetherill in Jamestown, 700 yards of Fort Adams, 400 yards of Sandy Point lighthouse on Prudence Island, 700 yards of the Prudence Island ferry dock and 500 yards of Arnold's Point in Portsmouth.
