WASHINGTON, Aug. 2 (UPI) -- The March failure of the Pegasus pipeline in Arkansas that spilled 5,000 barrels of oil was likely caused by original defects, a metallurgical report said.
About 5,000 barrels of a diluted form of heavy Canadian crude oil spilled from a 22-foot rupture in the Pegasus pipeline in Mayflower, Ark. Operator ExxonMobil Pipeline Co. said it had removed nearly all of the free-standing oil from the March spill and shifted to long-term remediation efforts
