(WPXI) – The Pennsylvania Public Utility Commission (PUC) Safety Division concluded its investigation into the August 2023 deadly house explosion in Plum. On August 12, 2023, a house on Rustic Ridge Drive exploded, killing six people and injuring others, as well as destroying three homes and damaging at least a dozen more. Tuesday, the PUC Safety Division concluded that there was no evidence that linked public utility jurisdictional assets to the cause of the explosion and fire. “While the PUC’s portion of the investigation has concluded, the Commission recognizes and deeply appreciates the profound level of concern this incident has generated within the community and our hearts go out to everyone impacted by this tragic event. The PUC remains steadfast in our commitment to public safety and our Safety Division experts are available as a resource to the Allegheny County Fire Marshal and other investigators who continue examining the cause of the Rustic Ridge Drive incident,” the report said.
