All water discharges are regulated under the National Pollutant Discharge Elimination System (NPDES), which was established under the Clean Water Act. Limits are put on parameters that may have a reasonable potential to exceed water quality standards, or to ensure compliance with technology standards for the iron and steel industry. Technology standards have been developed by the EPA and apply to specific processes within the mill.

The facility has expanded its notification requirements in the event of a spill or release. Additionally, this microsite was developed to provide timely updates for the public.
