Remember the Pegasus pipeline rupture that spewed tar sands into Arkansas the defects that caused it are more common than unique
The March 29 rupture of
Exxon Mobil’s Pegasus pipeline—which flooded a Mayflower, Arkansas
neighborhood with over 200,000 gallons of tar sands oil—was likely
caused by known “manufacturing defects,” with grave implications for the
tens of thousands of similarly built pipelines still in the ground and
operating, according to a review released Thursday.

An examination of the 70-year-old Pegasus pipeline and its
22-foot-gash found that the pipeline failure “resulted from an original
manufacturing defect of the electronic resistance welded (ERW) pipe,” according to a spokesman from the Hurst Metallurgical Research Laboratory.
Citing an ongoing investigation, both Exxon and the Pipeline and
Hazardous Materials Safety Administration (PHMSA) waited nearly a month
after receiving the report before releasing the details to Arkansas
newspaper Log Cabin Democrat Thursday. MORE
