AM/NS Calvert is sentenced for violating the Clean Air Act

MOBILE, AL - AM/NS Calvert, LLC was sentenced to a three years' probation and a $750,000 fine on October 10, 2024, for failure to report violations under the Clean Air Act.

According to court documents, AM/NS Calvert, LLC owns and operates a steel production facility, which includes an acid regeneration plant, in Calvert, Alabama. In February 2015, the Alabama Department of Environmental Management (ADEM) issued a Clean Air Act Permit for the acid regeneration plant designed to run on water. In April 2015, the permit was amended to require a caustic solution, which was necessary to meet air emission standards.

In August 2017, the U.S. Environmental Protection Agency (EPA) and ADEM conducted a joint inspection of the AM/NS Calvert acid regeneration plant. During the inspection, the facility was not using caustic solution in violation of the permit. Further investigation revealed the AM/NS Calvert acid regeneration plant did not use caustic for approximately 700 days during a two-year period.

United States Attorney Sean P. Costello said, "Together with our partners, we will continue to coordinate and do all that we can to protect the environmental resources in the Southern District of Alabama that are so fundamental to our communities, our economy, and our lifestyles."

The Environmental Protection Agency investigated the case.

Assistant U.S. Attorney Michael D. Anderson and attorneys from the Environmental Crime Section of the Department of Justice prosecuted the case on behalf of the United States.
