The rain over the Permian Basin had not stopped for three days, but the leak did not care. It seeped—slowly, steadily—through a girth weld that had been signed off by three different inspectors over two decades ago. The crude oil pooled in a low ditch, black and slick, reflecting the strobes of emergency vehicles like a fractured mirror.

Elena opened the digital version of B31.8S. She searched for "reassessment interval." The standard said that for pipes in HCAs, integrity assessments must be performed at intervals not exceeding seven years. She checked her records. The last in-line inspection on this segment was nine years ago. The company had requested a waiver, citing low corrosion rates and stable ground conditions. The waiver was approved by a state regulator who had since taken a job with a pipeline lobbying firm.
