South Portland City Council says no to tar sands oil export

The South Portland City Council passed an ordinance by a 6-to-1 vote Monday night that bans the export of Canadian tar sands oil from the city’s historic port. The ban means that the company that owns a pipeline that runs from Montreal will not be able to reverse the flow to allow the controversial crude to be loaded on to tankers in South Portland. The vote comes less than a year after a similar referendum on the issue failed in a close vote. The extraction of tar sands oil is controversial because of the greenhouse gases it produces and because of the dangers of transporting it over long distances.
