Draft supplemental environmental impact statement for the Keystone XL Project

"TransCanada Keystone Pipeline, LP (Keystone) proposes to construct, connect, operate, and maintain a pipeline system and ancillary facilities (e.g., access roads, pump stations, and construction camps) that would transport Western Canadian Sedimentary Basin (WCSB) heavy crude oil from its existing facilities in Hardisty, Alberta, Canada, and Bakken crude oil from an on-ramp in Baker, Montana, to Steele City, Nebraska. The proposed pipeline would connect to the existing Keystone Cushing Extension pipeline, which extends from Steele City, Nebraska, to Cushing, Oklahoma. The Gulf Coast Project, already under construction, would connect to the Cushing Extension, extending south to Nederland, Texas, to serve the Gulf Coast marketplace. In total, the proposed Project would consist of approximately 1,204 miles of new, 36-inch-diameter pipeline, with approximately 329 miles of pipeline in Canada and approximately 875 miles in the United States. The proposed Project would cross the international border between Saskatchewan, Canada, and the United States near Morgan, Montana, and would include pipeline generally with a 110-foot-wide temporary construction right-of-way and a 50-foot-wide permanent right-of-way in Montana, South Dakota, and Nebraska."

"Project-Specific Special Conditions -- To enhance the overall safety of the proposed Project, the Department and the Pipeline Hazardous Material Safety Administration (PHMSA) have developed 57 Project-specific Special Conditions. As a result, the proposed Project would be designed, constructed, operated, maintained, and monitored in accordance with the existing PHMSA regulatory requirements and in compliance with the more stringent 57 Project-specific Special Conditions that Keystone agreed to incorporate into the proposed Project, including more specifically incorporating the conditions into Keystone's written design, construction, and operating and maintenance plans and procedure. Appendix A, PHMSA 57 Special Conditionf for Keystone XL and Keystone compared to 49 CFR 195, presents the Special Condition and a comparison of the conditions with the existing regulatory requirements."
