At the Public Utilities Commission hearing in Pierre, a whistleblower testified earlier in the week, and Wednesday morning, TransCanada rebutted his testimony. Evan Vokes alleged TransCanada ignores regulations and uses faulty welding inspections. TransCanada says Vokes was a low-level employee without the required knowledge to make the allegations. SDPB’s Victoria Wicks reports on the hearing set to determine if TransCanada can still meet the conditions it agreed to in 2010, when the PUC first permitted the Keystone XL pipeline.
