- A comprehensive evaluation of the wastewater systems at the facility was conducted. This resulted in the development and implementation of an enhanced monitoring plan and the installation of additional monitoring systems and alarms that will expedite the identification of potential future complications.
- An operating and maintenance manual was developed for the water treatment systems, which requires additional employee training and enhanced maintenance policies. The approved 2018 edition can be found here:https://www.in.gov/idem/cleanwater/files/us_steel_decree_wwt_manual_revised.pdf
- More frequent water sampling and analysis are now conducted at the water treatment systems associated outfalls.
U. S. Steel has completed the corrective actions listed above, many of which are intended to ensure long-term improvements in environmental performance at the plant.
In addition to the completed repairs, the following recurring enhancements are ongoing:
- Additional water sampling and analysis at the facility;
- Improved notification procedures for potential unforeseen issues at the plant; and
- Increased employee training and equipment maintenance procedures.
The leadership team at the plant will also complete an environmentally beneficial project designed to monitor and report on water quality at seven locations along Lake Michigan’s Indiana shoreline, as outlined under the current draft of the consent decree.
The company will pay $1,232,475 in civil penalties and costs to entities including the State of Indiana, the National Oceanic and Atmospheric Administration, the U.S. Environmental Protection Agency and the U.S. Department of Justice.
The company has also agreed to stipulated penalties for future potential violations of the terms of the consent decree, the compliance requirements of the consent decree or the company’s National Pollutant Discharge Elimination System (NPDES) permit.
Water quality standards are set by the state through the Indiana Department of Environmental Management (IDEM) and are intended to protect both public health and aquatic life. 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.
Water discharges are governed under the National Pollutant Discharge Elimination System (NPDES), which was established under the Clean Water Act.
