Natural gas pipeline blast in Pennsylvania injures 1

News

GREENSBURG, Pa. (AP) – Authorities are trying to find out what caused a natural gas pipeline explosion in western Pennsylvania that destroyed one home, damaged at least three others and burned a fleeing homeowner.

Officials in Westmoreland County said the 30-inch Texas Eastern transmission line burst open around 8:15 a.m. Friday in Salem Township.

Spectra Energy said in a statement Saturday that the Pipeline and Hazardous Materials Safety Administration is investigating. Two parallel pipelines are being drained of natural gas, which should be done by the end of the day.

The company said the state environmental protection department is doing air monitoring and will also test surface water. Spectra Energy says it is installing a silt fence along the stream to protect the water from any potential rainwater runoff.
