Enbridge Energy has received approval from the Pipeline and Hazardous Materials Safety Administration (PHMSA) for the Line 6B crude oil pipeline restart plan.

Line 6B is a 30-inch, 283,000bpd line transporting light synthetics, heavy and medium crude oil from Griffith, Indiana to Sarnia, Ontario.

The approval outlines additional steps PHMSA requires Enbridge to complete prior to the regulator approving Line 6B’s return to service.

The approval of the Enbridge restart plan is the first of two separate approvals required from PHMSA before the line can be returned to service.

The second approval, still required from PHMSA, will be for the return to service of Line 6B based on compliance with the restart plan.

That plan includes requirements for appropriate public notifications and working with a third-party monitor to provide monitoring during the restart process, Enbridge said.
