Reuters reports that “the U.S. State Department on Friday corrected several errors it made in a key study evaluating the impact of the proposed Keystone XL pipeline, including an understatement of how many people could be killed on railroad tracks if the project were rejected and oil traffic by rail increased.”  

“The department said, however, these corrections had ‘no impact’ on the integrity of the conclusions of the January report, which played down potential environmental consequences of TransCanada Corp’s Canada-to-Texas project.”  

“The Obama administration has not yet decided whether to approve the project.”
