On March 1, the State Department released a supplemental environmental impact statement for the revised route of the proposed Keystone XL oil pipeline. The Department’s environmental review concluded the project would have minimal impact on Canadian oil sands production. However, it stopped short of making a specific recommendation on whether a permit should be granted or denied. The department is expected to issue a final review after a 45-day comment period. After the federal review process is completed, Secretary of State John Kerry and President Obama will decide whether a permit is in the national interest. While there is no mandatory deadline, a final decision is expected to come before summer.
