Last Tuesday evening a 68-year-old woman was home in her bed in Clarion County, PA when she heard an explosion and a wall collapsed on her. She freed herself from the rubble and drove to a neighbor’s house for assistance. The home, a garage and greenhouse were all destroyed as a result of the explosion and fire. The cause? Natural gas “migrating” in the basement of the home. A local delivery pipeline and a nearby transmission pipeline were both taken out of service while the PA Pennsylvania Public Utility Commission’s (PUC) investigation unit takes a look at the cause.
