A new report suggests the Keystone oil pipeline that ruptured last December in northern Kansas and spewed 12,000 barrels of heavy crude into a creek, had actually be years in the making.
Bloomberg reported that U.S. regulators warned more than a decade ago that the type of weld on the pipeline would trigger the worst spill in Keystone’s history. The Pipeline and Hazardous Materials Safety Administration had told operator TC Energy Corp at least five times that its building and operating practices posed safety risks.
The Keystone runs to Cushing, Oklahoma and on to refineries along the Gulf Coast.
