The US Chemical Safety and Hazard Investigation Board (CSB) has completed its investigation into the June 4, 2025 explosion and fire at Shell Polymers Monaca in Pennsylvania, an incident that caused extensive damage to the giant petrochemical complex and could, under slightly different circumstances, have had far more serious consequences.

Shell Chemicals Appalachia LLC has agreed to pay $15 million to resolve Pennsylvania air-pollution violation complaints concerning its Beaver County plastics plant, according to reporting by the Beaver County Times.
