Proponents of a controversial liquefied natural gas plant in Maine say a study ordered by the Canadian government has found there is no reason to ban supertankers from the Bay of Fundy, as Ottawa has threatened to do if the U.S. approves the project. Downeast LNG said the environmental study found there were no immediate risks of having LNG supertankers go through the Bay of Fundy, part of which is split by the New Brunswick-Maine border, to the proposed plant. Dean Girdis, the Washing-ton-based president of Downeast LNG, said the long-awaited review, done by Ottawa-based Senes Consultants Ltd., found there was no immediate danger of having the 283-metre long ships go through a narrow passage in Canadian waters called Head Harbour if precautions were taken.
