"This pipeline delivers strong benefits to the United States," said Keystone Pipeline of building a proposed oil pipeline from Alberta, Canada to its final destination in Texas.

"Pipelines are the safest way of delivering these products and Nebraska already has thousands of miles of pipelines delivering products across the state," said Jeff Rauh, the Pipeline Project Representative.

Rauh said problems on the already existing pipelines are rare, as would problems be with the proposed pipeline.

"Keystone will feature better steel, better manufacturing processes, better corrosion protection and additional safety features which means that the risk of a problem on this line is even less than on this line," said Rauh.

Still there is always the worst case scenario, like the massive BP oil spill in the Gulf . This worries opponents to the pipeline like Duane Hovorka the executive director for the Nebraska Wildlife Federation.

"We've seen it in the gulf of Mexico, a giant oil spill," said Hovorka. "What could happen if that pipe starts leaking and it doesn't have to be a big leak. It could be a small leak that goes undetected for a long time."

Hovorka said even if there is never an oil spill, the Keystone Pipeline presents other negative implications.

"There's greenhouse gas implications for climate change," said Hovorka. "We also think it has some really important implications for Nebraska because you're running a pipeline right through the heart of the sandhills; right over the Ogallala Aquifer; across rivers like the Niobrara and the Platte; and through wetlands in the rainwater basin."

Still Keystone insists on it's state of the art safety features.

"We ensure that we are ready to respond to any problem that is on this pipeline," said Rauh.

While Keystone maintains its stance on the safety of the proposed pipeline, opponents like Hovorka say they want to see resources going toward alternative energy, clean energy and energy efficiency, instead of building more ways to transport gas and oil.

"We need to pursue energy conservation and renewable energy in a big way, so we can make pipelines like this unneeded," said Hovorka.

For now, it's up to U.S. Secretary of State Hillary Clinton to move the motion forward or kill it.
