and unable to pay their bills". The suit went on until 2007, when a judge ruled in favor of Renco and against the DOJ. On August 17, 2010, a 10th Circuit Court of Appeals ruling overturned a District Court judge's October 17, 2007, decision that the U.S. Magnesium facility in Rowley, Utah was not illegally disposing five wastes. The initial lawsuit DOJ filed on behalf of EPA in 2001 claimed U.S. Magnesium was not following regulations promulgated under the Resource Conservation and Recovery Act of 1976, which dictates how waste byproducts must be disposed. Renco continues to operate the business under the name US Magnesium. At this point, US Magnesium is the only magnesium producer in the United States. The EPA published its proposal to place the US Magnesium facility on the National Priorities List (NPL, a "Superfund site" under CERCLA) in the Federal Register on September 3, 2008. The National Priorities List (NPL) is a list of places, commonly known as "superfund sites," considered national priorities for environmental remediation because of known or threatened releases of hazardous substances.USM filed its petition for review of the listing in the United States Court of Appeals for the District of Columbia Circuit on November 5, 2009. On January 14, 2011, the United States Court of Appeals sided with the EPA and upheld placing the site on the National Priority List. AM General In 1993, Renco acquired AM General from the LTV Corporation to help LTV emerge from bankruptcy. Terms included a $67.5 million cash payment with the remainder to be paid in various forms over a 10-year period. AM General produced vehicles for industrial, military and government use, including the Humvee. On August 20, 2004, it was announced that Ronald Perelman's MacAndrews & Forbes Holdings company would buy 70% of AM General from Renco. The deal reportedly cost close to US$1 billion. Environmental track record United States The Renco Group's environmental record in the U.S. related to Doe Run provides a good example of this development. In 1998, the EPA placed Renco Group business holdings 10th on the nation's largest polluter list primarily because of emissions from US Magnesium in Utah (formerly MagCorp). (US Magnesium was purchased by Renco in 1989 in the year in which its emissions peaked at 119,000 tons per year.) By 1998, the year the Renco was placed on the EPA list, it had reduced emissions at US
