Friends of the Earth, a grassroots global environmental group that represented in 77 countries, said Friday that a pipeline carrying oil from Canada into the U.S. that ruptured and spilled more than a million gallons of oil into the Kalamazoo River in Michigan is the kind of danger that could happen if a proposed oil pipeline is built in Nebraska.

According to Friends of the Earth, crews are attempting to prevent the spilled oil from reaching Lake Michigan, where it could cause catastrophic environmental damage.

Before this week’s oil spill, federal officials criticized Enbridge, the Canadian tar sands oil giant that owns the pipeline, for ignoring corrosion that compromised the pipeline’s integrity, according to Friends of the Earth. 

TransCanada, another major Canadian tar sands oil company, is currently seeking Obama administration approval for its proposed Keystone XL tar sands oil pipeline, which would travel 1,700 miles from Canada to refineries near Houston. The company is also seeking a safety waiver that would allow it to use thinner-than-normal steel and pump oil at a higher-than-normal pressure.

The Keystone XL pipeline would cross 71 rivers and streams including the Ogallala Aquifer, putting water supplies and the environment at risk. The Ogallala, which is the nation’s largest aquifer, provides drinking and agricultural water for eight states and supports one-fifth of the wheat, corn, cotton, and cattle produced in the United States. 

“This disastrous oil spill in Michigan is yet another wake-up call to the tragic impacts of our oil dependence,” said Alex Moore of Friends of the Earth.”Coming on the heels of the Deepwater Horizon disaster in the Gulf of Mexico, this spill reinforces the need for us to build a clean energy economy, not more pipelines.”

Moore said Enbridge and other oil companies like BP have “deliberately cut corners on safety without respect for the people or communities they put at risk.”

“President Obama should take a long, hard look at this disaster and deny a permit for the Keystone XL pipeline, the next on Big Oil’s wish list,” Moore said.

For months, Moore said ranchers, environmentalists, and public health advocates have challenged TransCanada’s plans to build another pipeline to carry the “world’s dirtiest oil from Canada’s tar sands into the United States.:

“ The Environmental Protection Agency recently handed the State Department’s draft analysis of the proposed pipeline’s environmental impacts a failing grade, in part because it failed to address the dangers the pipeline would pose to communities along its path,” Moore said.
