As of yesterday afternoon, the oil that caused the sheen was no longer being discharged from the outfall at US Steel. Booms contained most of the oil, but some sheen was observed outside the boomed area. IDEM continues to investigate the cause of this incident and the potential repercussions under the recently entered consent decree and state agreed order.
