TransCanada receives approval notice for Keystone pipeline restart

>

The Canadian pipeline company said that regulator PHMSA has approved a return to service plan for a controlled start. It was not immediately clear when and if the pipeline had restarted. 

The pipeline, which delivers light and heavy crude from Hardisty, Alberta, to Cushing, Oklahoma, and Illinois, was shut last Saturday after a potential leak was discovered in South Dakota.
