A BP subsidiary will pay a $40 million penalty and install technology to control releases of benzene and other contaminants at its Whiting oil refinery on the Indiana shoreline of Lake Michigan, Biden administration officials said Wednesday.

The actions will settle a civil case against BP Products North America Inc. filed by the U.S. Department of Justice and the Environmental Protection Agency, which described the penalty as the largest ever under the Clean Air Act for pollution from a structure. Additionally, the company will invest around $197 million in improvements.
