Three groups, the Center for Biological Diversity, the Western Nebraska Resources Council and Friends of the Earth plan to file a lawsuit in federal court in Omaha, against TransCanada's Keystone XL pipeline, saying TransCanada has illegally cleared a 100-mile pipeline corridor through the Nebraska Sandhills, despite a federal law that prevents the launch of projects before they receive approval.
