the Steel Workers Pension Trust, $0.10/hour increase in 401(k) contributions, and uncapped profit-sharing. Environmental record During the 1948 Donora smog, an air inversion trapped industrial effluent (air pollution) from the American Steel and Wire plant and U.S. Steel's Donora Zinc Works in Donora, Pennsylvania. In three days, 20 people died... After the inversion lifted, another 50 died, including Lukasz Musial, the father of baseball great Stan Musial. Hundreds more lived the rest of their lives with damaged lungs and hearts. But another 40 years would pass before the whole truth about Donora's bad air made public-health history. Today the Donora Smog Museum in that city tells of the influence that the hazardous Donora Smog had on the air quality standards enacted by the federal government in subsequent years. Researchers at the Political Economy Research Institute have ranked U.S. Steel as the 58th-greatest corporate producer of air pollution in the United States (down from their 2000 ranking as the second-greatest). In 2008, the company released more than one million kg (2.2 million pounds) of toxins, chiefly ammonia, hydrochloric acid, ethylene, zinc compounds, methanol, and benzene, but including manganese, cyanide, and chromium compounds. In 2004, the city of River Rouge, Michigan, and the residents of River Rouge and the nearby city of Ecorse filed a class-action lawsuit against the company for "the release and discharge of air particulate matter...and other toxic and hazardous substances" at its River Rouge plant. The company has also been implicated in generating water pollution and toxic waste. In 1993, the Environmental Protection Agency (EPA) issued an order for U.S. Steel to clean up a site on the Delaware River in Fairless Hills, Pennsylvania, where the soil had been contaminated with arsenic, lead, and other heavy metals, as well as naphthalene. Groundwater at the site was found to be polluted with polycyclic aromatic hydrocarbons and trichloroethylene (TCE). In 2005, the EPA, United States Department of Justice, and the State of Ohio reached a settlement requiring U.S. Steel to pay more than $100,000 in penalties and $294,000 in reparations in answer to allegations that the company illegally released pollutants into Ohio waters. U.S. Steel's Gary, Indiana facility has been repeatedly charged with discharging polluted wastewater into Lake Michigan and the Grand Calumet River. In 1998 the company agreed to payment of a $30 million settlement to clean up contaminated sediments from a five-mile (8 km) stretch of the river.
