Line 5 restart slips to September 6-8 as crews switch from flaring to compressed air

Ten days into the Iron County shutdown, Enbridge has moved its return-to-service window back by up to three days and changed vapor-removal method at the excavation. Wisconsin health officials have now reviewed the air data and found no concern outside the evacuation zone but an elevated long-term benzene reading inside it. PHMSA still holds the site; the state DNR is still waiting at the fence.

  2. 02

    PHMSA has not yet authorized Wisconsin DNR access to the Line 5 excavation; water monitoring wells are in, sampling pending.2

    Analysis

    State regulators locked out of a federal site is a jurisdiction friction worth tracking past the restart.
