A parked third-party flatbed rolled into a Line 5 excavation, shutting the line after ~31,000 barrels of propane/butane vaporized. This is a construction-controls loss, not a corrosion or third-party dig-in. Underwriters on pipelines, contractors, and relocation projects should treat excavation vehicle control, isolation-point inventory, and BI on a 645-mile, multi-product line as one claim family. | Source: Tank Transport, 31 Aug 2026, https://tanktransport.com/2026/08/enbridge-line-5-release/ - Caveat: volumes are company estimates, not a final PHMSA total.
