The State Department concluded in its studies in August 2011 that the TransCanada Keystone XL pipeline can be operated without causing environmental damage, if operated under strict regulations. A round of public hearings organized by the State Department along the pipeline route from rural Montana to Nebraska and Texas has brought out both supporters and people fearing a spill. U.S. Senators in Nebraska have called for a rerouting out of concerns about the Ogallala Aquifier that lies under the Great Plains. Rural states like Montana see the jobs issue as crucial. Others including Debra Medina, a former candidate for Texas Governor, expressed fears at a rally in Austin that the property rights of landowners would not be respected.
