Cleveland-Cliffs Butler began operating in 1908 under the Forged Steel Wheel Company. The plant has had many owners, including (chronologically) Columbia Steel (1920-1927), Armco (1927-1999), and AK Steel (1999-2020).[2] AK Steel merged with Cleveland-Cliffs in 2020 for $1.1 billion, at which point the Butler plant transferred to Cleveland-Cliffs.[3] The facility now produces semi-finished and finished rolled steel which is used in power and distribution transformers, as well as stainless and carbon converters.[4]

The electric arc furnace at Butler began operating in 2011 as part of a $180 million upgrade to the plant.[5]

Environmental Compliance & Worker Safety

The facility underwent major renovations in the early 2000s to reduce its water and air pollution, after AK Steel entered into an agreement with the EPA in 2001 to convert its facilities. AK Steel spent around $26 million on retrofits.[6]

In 2004, AK Steel agreed to a $1.2 million settlement with the EPA comprising of a $300,000 penalty and $900,000 in additional spending to reduce smog-producing ozone at their facilities, which included the Butler facility.[7]

In 2011, the Occupational Safety and Health Administration (OSHA) fined AK Steel $206,000 for worker safety violations at the Butler facility.[8]

In March 2022 a fire broke out at a finishing line at the plant. There were no injuries reported.[9] 2 months later in May 2022, 7 workers were exposed to hyrdoflouric acid while working at the plant.[10]
