The pipeline that exploded in Beaver County’s Center Township Monday originates in Butler County, officials report.

Center Township Police Chief Barry Kramer said at a news conference that the pipeline begins in “northern Butler County” and leads to Bulger, Washington County.

In a written statement issued by the pipeline’s owner, Dallas-based Energy Transfer Partners, the company identified the pipeline as a 24-inch methane gas gathering line, called the Revolution Pipeline.

The statement points to a landslide in the area near the time of the explosion, which occurred at about 5 a.m. No one was injured, and the fire was extinguished by 7 a.m., the statement says.

As for a cause, the company indicates weather events may be to blame: “An initial site assessment reveals evidence of a landslide in the vicinity of the pipeline.” Heavy rains also were pointed to as a cause.

Energy Transfer works with EdgeMarc Energy in Western Pennsylvania. EdgeMarc has facilities in Butler County, and the pair have partnered in transporting cryogenic gas in the region.

The company reported that automated detection systems shut off valves in response to the explosion, thereby allowing the fire to die out.

The Pennsylvania Public Utility Commission had little to report on the matter, except that an investigation is in its early stages and details won’t be revealed until later.

About 25 to 30 Center Township homes were evacuated in the wake of the blast. Resulting flames destroyed a home, two garages and several vehicles.

Witnesses reported seeing an orange glow fill the sky as it burned.
