Oil from a spill at ArcelorMittal Steel Mill in Georgetown, S.C., creates a sheen on the water in the Georgetown harbor Thursday, March 20, 2014. Upon learning of the spill, the mill immediately contracted HEPACO environmental contracting firm to begin containing and recovering the oil, and Coast Guard pollution responders are continuing to oversee the response.
