When a gas pipeline ruptured in the Pacific Northwest, the region’s oil and gas boom was about to crash

By: John VignolaPublished: May 06, 2017 12:45:25An explosion that took out a pipeline in the Washington area has brought the region to the brink of a natural gas boom.

The blast occurred in a pipeline that transports natural gas from Alberta to Portland, Oregon.

The pipeline exploded at about 4:20pm local time (6:20am ET), according to the U.S. Pipeline and Hazardous Materials Safety Administration (PHMSA).

The cause of the explosion is still under investigation, but authorities say it occurred when the pipe failed to fully tighten.

The rupture occurred about 60 miles (96 kilometers) from Portland and had a volume of more than 10 billion cubic feet (bcf), the agency said.
