WASHINGTON — The Canadian company trying to build the disputed Keystone XL pipeline in the U.S. submitted a new application for the project today after changing the route to avoid environmentally sensitive land in Nebraska.

TransCanada said it applied again to the State Department for permission to build the pipeline to carry oil from so-called tar sands in western Canada to a company hub in Steele City, Neb. From there, the project would link up with other pipelines operated by the company to carry oil to refineries on the Texas Gulf Coast.

President Barack Obama blocked the pipeline earlier this year, citing uncertainty over the Nebraska route, a decision that drew fire from Republicans and industry groups.

TransCanada had proposed a new route last month that would veer east around the groundwater-rich Sandhills region before looping back to the original route.

State Department approval is needed because the $7 billion pipeline would cross a U.S. border. The department confirmed today the application for the new route had been received.
