The head of the company that operates the Trans-Alaska Pipeline announced his retirement Wednesday after criticism by a congressional committee and the internal watchdog unit of majority owner BP.
Kevin Hostler will step down as CEO of Alyeska, the BP-dominated consortium that operates the 800-mile pipeline, on September 30, the company announced.
"Retiring at the end of September is good for the pipeline, and it allows enough time for a proper transition," Hostler said. "Our executive team and other Alyeska leaders have worked toward developing leadership skills so that any transition in the organization is seamless."
