If the Keystone XL pipeline is built, a TransCanada contractor will set up three work camps, referred to as “man camps” by pipeline opponents. A TransCanada employee says up to 1,200 people will live in the camps, located in Harding, Meade, and Tripp counties. Some interveners express fears about the safety of the surrounding areas when that many people, most of them men, arrive. SDPB’s Victoria Wicks reports on this last witness in the Public Utilities Commission hearing that started July 27 and concluded Wednesday.
