WASHINGTON, D.C._Public comment on the Keystone XL pipeline had been scheduled to wrap up in early May but today the Obama administration announced it was extending the comment period.
The extension could delay a final decision on the pipeline, which would transport oil from Canada to the Gulf Coast.
State department officials did not say how long the extension would be but did say more time was needed to address the legal challenges facing the pipeline's route in Nebraska.
Environmentalists have questioned the impact the pipeline would have on climate change. But the state department report now under extended review found that impact would not be significant.
