"That should not be the case. PHMSA needs very direct authority if there's a potential hazardous situation." In a statement Enbridge Energy, the company Canadian company that operates Line 5, said they support the new regulations. "We're encouraged to see PHMSA finalize these important rulemakings focused on further enhancing the safety of our nation's critical energy infrastructure," Spokesman Ryan Duffy said via email. "We take a comprehensive approach to monitoring our pipeline systems to ensure safe and reliable operations. Enbridge intends to fully comply with the new PHMSA rules." The rules take effect on July 1, 2020.
