Keystone XL comment window to State Department now closed, but it won't be the last opportunity

From the State Department's website:

     On April 22, the comment period on the Draft Supplemental Environmental Impact Statement closed.
     After the comment period, the Department will make appropriate revisions and publish a Final SEIS. Next, the Department will seek the views of other agencies and then make a determination as to whether issuance of a Presidential Permit for the Keystone XL pipeline would serve the national interest. The national interest determination by the Department involves consideration of many factors, including energy security; environmental, cultural, and economic impacts; foreign policy; and compliance with relevant federal regulations.
     The Department intends to provide an additional opportunity for the public to comment during the National Interest Determination (NID) period that will begin with the release the Final SEIS. This additional public comment period will provide a further opportunity for the public to provide input on this proposed project. The Department will provide the details on the NID comment period at a later date.
