Letters to the editor: Tar sands pipeline's pros and cons

Your Feb. 28 article, "Scrutiny urged on piping of tar sands through Maine," was an excellent summary of two versions of the same facts.

TAR SANDS

Mining trucks carry oil-laden sands at the Albian Sands project in Alberta, Canada, in 2005. Readers weigh the impact of piping tar sands oil through Maine.

The Associated Press

Elders for Future Generations, whose mission is to speak out on current issues in Maine that will have an impact on our grandchildren, urges your readers to pay close attention to the need for much more scrutiny of all the facts on transporting tar sands oil in the Portland-to-Montreal pipeline.

Whichever side of the proposal you choose to believe in, the need for a presidential permit and the related environmental impact assessment it requires, is critical.

Why?

Because reversing the flow of oil in the existing pipeline from Montreal to South Portland is subject to minimal state and federal evaluation and regulation.

Because the pipeline is 62 years old and was built before the current standards.

Because the pipeline crosses numerous waterways where a pipeline fracture could lead to oil spilling into Sebago Lake, the water supply for 200,000 people in Greater Portland.

Because tar sands oil is corrosive, toxic and difficult to clean up.

Because the proposed 70-foot stacks at the Bug Light pier in South Portland would be an eyesore and a potential source of toxic off-gases that will have a negative effect on quality of life in that scenic area.

And because the oil will be shipped out of country and be of limited value to the U.S. and Maine.

Don't agree? Fine. Let's get the facts and have that environmental impact study and a presidential permit process. We are gratified that U.S. Reps. Chellie Pingree and Mike Michaud agree with our position and have asked the secretary of state to require this process.

We'll all sleep better knowing there will be a decision based on a serious weighting of the costs and benefits of this proposal done under public scrutiny. And future generations will thank us.

Many thanks to U.S. Reps. Chellie Pingree, Mike Michaud and 16 other members of Congress for urging Secretary of State John Kerry to require an environmental impact study before tar sands are pumped from Montreal to South Portland through Maine's old pipelines.

Your coverage of the tar sands issue on Feb. 28 and March 2 ("Industry encouraged by tar sands pipeline study") omitted four critical facts:

Tar sands is radically different from crude oil.

Tar sands is more likely to create pipeline spills.

Tar sands spills cannot be cleaned up.

Two smokestacks would have to be built on the pier in South Portland to burn off toxic chemicals used for tar sands transport.

Tar sands is essentially composed of bitumen, also known as asphalt, the same substance used in paving roads. It contains only 10 percent oil, the rest being clay and sand mixed with 5 percent water. This makes tar sands a thick, abrasive substance that is a misnomer to be called "oil."

High heat is a principal reason for pipeline leaks and ruptures. The higher the level of bitumen, the higher the heat. Studies show the risk of leaks is significantly greater when heat is above 100 degrees Celsius. Tar sands heat is 150.

Nearly 1 million gallons of tar sands still lie at the bottom of Michigan's Kalamazoo River because the Environmental Protection Agency could not remove it. Businesses have closed, real estate values dropped, people relocated and cleanup stations set up along the river in case of contamination from contact.

Maine's pipeline runs extremely close to Sebago Lake (the source of our drinking water) and crosses its main tributary, the Crooked River, multiple times.
