Pipeline protest ends at White House

A two-week civil disobedience campaign against the controversial Alberta-to-Texas oil pipeline ended Saturday amid uncertainty over whether U.S. President Barack Obama will allow the project to go ahead.

Protesters held a final rally outside the White House after two weeks of daily sit-ins where roughly 1,250 people were arrested.

Organizer Bill McKibben, a well-known environmentalist and author, said the demonstrations have helped raise awareness about the environmental impact of the proposed project and Alberta's oilsands.

The big question now is whether the Obama administration will decide to block the pipeline, McKibben said.

"Canada's putting on full diplomatic pressure, and the oil companies have more money than god, but we've changed the odds a little bit these last two weeks," he said Saturday.

On Saturday, Natural Resources Minister Joe Oliver told CBC News he was "increasingly positive" theCalgary-based TransCanada Corp.'s proposed Keystone XL oil pipelinewould get the green light from the Obama administration.

Oliver insisted the pipeline would have a "degree of safety greater than" the typical domestic pipeline systemand would benefit the U.S. and Canadian economies by creatingjobs and securing a domestic source of oil.

The U.S. State Department released its final environmental assessment in August of the $7-billion pipeline, determining the project would cause minimal risk. Energy Secretary Steven Chu also suggested this week that the pipeline was likely to get approved due to Canada's close ties with the United States.

In an interview Saturday, Oliverstressed the2-year study of the environmental impact of the pipeline concluded there would be no significant effect on most resources along the proposed projects corridor.

But opponents say the pipeline which would carry oilsands crude through six U.S. states to refineries in Texas endangers a major source of water to millions of people.

Bill Erasmus, the Assembly of First Nations regional chief for the Northwest Territories who isin Washington D.C. supporting the protest, said the pipeline goes through the Ogallala Aquifer, which covers 450,000 square kilometres and includes portions of Nebraska, South Dakota, Wyoming, Kansas, Colorado, Oklahoma, New Mexico and Texas.

"If there is a spill in that aquifer, it will mess up the water for about four million people," Erasmus told CBC News on Saturday. "The governor of Nebraska this week announced his opposition [because of that]."

Erasmus alsodismissed claims the oil pipeline iscritical fornational security.

"This oil is going to be transported to the Gulf of Mexico; it is not for U.S. consumption," Erasmus said. "Its for the highest bidder, its for the open market."

Klein among arrested

Erasmus said the oilsands continue to have aharmful effect on many indigenous communities in Alberta and Northern Canada.

"Were finding drastic levels of low waters in our area," Erasmus said. "We're also finding the waters are being polluted from the massive tailings ponds that are at the tar sands and people in places like Fort Chippewa can no longer eat their fish. They cant drink the water."

More than 1,000 peaceful protesters have been arrested by U.S. Park Police at the White House demonstration in the past two weeks and escorted to police vans in the past two weeks.

Canadian author Naomi Kleinand aboriginal activist Gitz Deranger were among dozensarrested on Friday in front of the White House. Actors Daryl Hannah and Margot Kidder were also arrested during the two-week campaign.

Former U.S. vice-president Al Gore, now a leading environmentalist, has also weighed in.

In a plea to Obama earlier this week, Gore urged the president to block the pipeline, calling the oilsands "the dirtiest fuel on the planet."

The Obama administrationhas saidit will make a final decision on the pipeline by the end of the year, after it determines whether the project is in the U.S. national interest.
