According to the EPA, between October 1, 2004 and January 17, 2008, APM Terminals Pacific Limited – one of the world's largest container terminal companies – reportedly discharged industrial-activity storm water at its marine shipping container terminal facility, a violation of Clean Water Act and the California National Pollutant Discharge Elimination System.
Polluted runoff is a major cause of water pollution, which can carry pollutants from industrial sources, such as metals, oil and grease, acidic wastewater, bacteria, trash, and other toxic pollutants into nearby water sources.
The EPA requires industrial facilities to prevent water pollution by complying with federal and state water pollution requirements.
