Nebraska Governor Dave Heineman (R) approved a revised route January 22 for the Keystone XL oil sands pipeline through the state, removing a major hurdle for the proposed project. The governor also sent a letter to President Obama and Secretary of State Hillary Clinton informing them of his approval of the route. The State Department is drafting a supplemental environmental impact statement that will include the revised route and the governor’s approval; the draft will be released for public comment at the end of the first quarter.
