The State Department said Friday that the Keystone pipeline expansion should have no significant effect on the environment along its proposed route, but stopped short of saying whether or not the controversial pipeline should be approved.

If the company behind the pipeline, TransCanada, follows all the rules, its “construction and normal operation” of the pipeline should pose no major risks, the State Department said in its draft environmental impact statement. That statement is now open for a 45-day public comment period. The Obama administration will make its decision about the pipeline later this year, likely in mid-summer.
