The Environmental Protection Agency is adding the Wilcox Oil Company site in Creek County to the National Priorities List of Superfund sites.
The Wilcox site is located about 35 miles southwest of Tulsa. It consists of the former Lorraine and Wilcox Refinery. The two companies operated refineries and associated facilities on the property between 1915 and 1965.
The 125-acre site includes remnants of the former oil refining operations and tank farms. Contaminants at the site include metals - mainly lead - and polycylic aromatic hydrocarbons, a group of chemicals found in crude oil that might cause cancer or reproductive and skin effects.
Adding the site to the Superfund list will allow the EPA to evaluate the nature and extent of the site's contamination and assess how best to treat it.
