FINAL Supplemental Environmental Impact Statement: Keystone XL (State Department)

Executive Summary HERE

These review documents are as massive as the applications that are submitted for review.  Reading the entire report is not practical or of interest to me. I tend to look at those aspects that I find most important from my perspective. For me, wetlands, wildlife, mitigiation and reclamation, routing alternatives, and the full Volume 3: Chapter 4 - environmental consequences section are of most interest.  I have listed a few of these direct links below.
4.0 Environmental Consequences  [117 Kb] 
5.2 Route Alternatives  [3314 Kb] 
Appendix B Potential Releases and Pipeline Safety  [500 Kb] 
Appendix D Waterbody Crossing Tables and Required Crossing Criteria  [9510 Kb] 
Appendix G Construction Mitigation and Reclamation Plan  [7665 Kb]

New Keystone XL Pipeline Application

On May 4, 2012, the Department of State received a new application from TransCanada Corp. for a proposed pipeline that would run from the Canadian border to connect to a pipeline in Steele City, Nebraska. The new application includes proposed new routes through the state of Nebraska.

The Department’s responsibility, under Executive Order 13337, is to determine if granting a permit for the proposed pipeline would serve the national interest. The Department is considering this new application on its merits. Consistent with the Executive Order, this involves consideration of many factors, including energy security, health, environmental, cultural, economic, and foreign policy concerns.
