A former TransCanada engineer claims the company knew that its Bison natural gas pipeline in Wyoming had faults before it ruptured last year but ignored the problems in the rush to bring it online.
Evan Vokes oversaw work on the pipeline and was terminated in May for undisclosed reasons. He told the newspaper that he saw problems with pipe alignment welding, excavation and backfilling. He said rocks were left in the pipeline’s ditch and they could have caused dents in the line.
"I sent (TransCanada) an email saying that they were in serious trouble," he said. "It was a pretty rough show."
A 60-foot section of the pipeline exploded on July 20, 2011, 20 miles northwest of Gillette, shaking the ground and spewing a brown cloud into the sky. The gas didn’t ignite. The pipeline, which runs across southeastern Montana into North Dakota, began operating in January 2011.
TransCanada is seeking to build the controversial Keystone XL pipeline from western Canada to refineries along the Texas Gulf Coast.
