Waterford residents passed a municipal resolution Saturday opposing the transport of tar sands oil through the Portland to Montreal pipeline.

It is the third Maine community to officially oppose using the pipeline for tar sands oil, joining Casco and Bethel. A similar resolution goes before Harrison voters June 11. Raymond, Windham and South Portland are also considering votes opposing the transport of tar sands oil from Canada to Maine.

Portland City Council is studying whether to ban the purchase of tar sands oil for city operations.
The owner of the Portland-to-Montreal pipeline has not announced plans to start transporting the heavy form of petroleum from Canada but has not ruled out such a move in the future.

Opponents say the oil, produced from vast tar sands oil deposits in Alberta, is more corrosive than the crude oil that now runs through the pipeline and its production will speed up global warming.

Proponents say the oil is not more likely to spill or create environmental problems than the crude oil now flowing through the pipeline.
