On September 19, 2011, a number of Indigenous tribal leaders in the United States and Canada were arrested for protesting the Keystone XL outside the White House. According to Debra White Plume, a Lakota activist, Indigenous peoples "have thousands of ancient and historical cultural resources that would be destroyed across treaty lands". TransCanada's Pipeline Permit Application to the South Dakota Public Utilities Commission states project impacts that include potential physical disturbance, demolition or removal of "prehistoric or historic archaeological sites, districts, buildings, structures, objects, and locations with traditional cultural value to Native Americans and other groups".
