LINCOLN, Neb. — The developer of the Keystone XL pipeline is reversing course in Nebraska and will drop its eminent domain lawsuits against landowners who don't want the pipeline running through their property. TransCanada Inc. announced Tuesday that it will stop pushing for the project under a state law that's now being challenged in the courts. The company says it will instead seek approval through the Nebraska Public Service Commission, an agency that regulates pipelines, warehouses and grain bins. TransCanada won approval from former Gov. Dave Heineman, but the state law that allowed him to do so remains mired in court. TransCanada spokesman Mark Cooper says the company believes that applying through the commission will reduce the local conflicts. Jane Kleeb, a leading pipeline opponent, says the company was losing ground in Nebraska.
