SOUTH PORTLAND, Maine (AP) - A company that operates a pipeline in Maine has surrendered a permit that has raised concerns about plans to transport tar sands oil to South Portland.
The Portland Pipe Line Corp. announced Thursday that it surrendered the 2009 permit with the state's environmental department to construct two vapor control units in South Portland. It would need those to reverse the flow of the Portland-Montreal pipeline and send tar sands to the city.
A proposal on South Portland's November ballot is designed to block that from happening.
Even with the outstanding permit, the company said it had no plans to transport tar sands.
But opponents have said the fact that the company still has the permit, which would have been valid until February, proves it has its eye on the oil.
