The State Department clears the Keystone XL pipeline project of any environmental concerns, but will President Barack Obama approve it?

TransCanada's Russ Girling believes the White House is out of excuses with the results of this latest environmental impact study that raises no issues with a pipeline which ultimately could deliver crude from the oil sands of Canada to the Texas Gulf Coast.

“All of our customers continue to support it, the states along the route have approved it, and we're are ready, willing and wanting to put 9,000 American men and women to work as quickly as we can,” said Girling.

However, Dan Kish at the Institute for Energy Research isn't so confident.

“This has taken longer than World War II, it's taken longer than any other pipeline ever conceived,” he tells KTRH News.

Kish says while the announcement appears big, we've already seen four of these reports before.

“None of them raised serious problems either, yet we find ourselves in our sixth year of a decision over whether a pipeline that could provide a lot of jobs and new energy should be built and is in the national interest,” he says.

Because the project was an executive order under President George W. Bush, Kish says Obama is under no deadline to make a decision.

White House spokesman Jay Carney reaffirmed Kish's concerns by insisting more input is needed, calling for additional studies and public comment.

“I'm not going to make a statement about what the president is going to do based on something that hasn't happened yet,” Carney told reporters Friday.

Many believe Obama will simply sit on the project, and leave it for the next president to deal with.
