"Reports that would reveal whether Exxon properly maintained its Pegasus pipeline are being kept from the public. The data has national ramifications."
"The 1940s-era construction process that ExxonMobil said caused an oil pipe to rupture in Arkansas earlier this year is a common and well-documented problem the pipeline industry has battled for decades—and one the industry believes can be detected and controlled with appropriate vigilance.
"With proper inspection and maintenance, these catastrophic events can be prevented," said Mohammad Najafi, a pipeline construction expert and engineering professor at the University of Texas at Arlington. "As pipelines exceed their design lives, they need more maintenance and a proper asset management strategy to prevent or minimize these ruptures."
That leaves the public and regulators with two critical questions: Did Exxon manage and test its broken Pegasus pipeline according to established guidelines? And, if it did, is the Arkansas accident a warning that other pipelines might be at risk?"
