Last week, Nebraska Gov. Dave Heineman approved a reroute of the oft-disputed Keystone XL pipeline. Previously, the pipeline was slated to cross not only the Nebraska Sandhills but the Ogallala aquifer as well, two areas that had environmentalist groups ready for war. The resultant pressure caused Gov. Heineman to withdraw his support for the pipeline as planned, and President Obama denied the required Presidential Permit in January 2012.
