"In areas of northern Nebraska where the soil is susceptible to erosion, the pipeline company, TransCanada, would use special procedures to build the pipeline.
TransCanada also agreed to 57 special conditions governing the pipelines construction, operation and maintenance which would be enforced by the Pipeline and Hazardous Materials Safety Administration.
The DEQ said in the event of an oil spill, the impact on the aquifer should be localized and TransCanada would have to pay for cleanup. TransCanada agreed to carry at least $200 million in liability insurance to cover sudden and accidental pollution incidents from Keystone XL Pipeline in Nebraska.
TransCanada first applied for a federal permit to build the pipeline in 2008, but ran into stiff opposition in Nebraska. In late 2011, TransCanada agreed to reroute the pipeline around the Sandhills, but the project still faces considerable opposition in the state, where about 800 people showed up for the final DEQ public hearing on the project in December."
Yes, I got that, it’s from the article.
Your suggestion that the State Dept. is waiting for study results, and in particular, the border crossing is something I’m not aware of.
