8716 N GRANVILLE ROAD

The 88-acre Moss-American Superfund site is located in Milwaukee, Wisconsin. In 1921, the T.J. Moss Tie Company established a wood-preserving facility west of the Little Menomonee River in Milwaukee and the plant reportedly treated wooden railroad ties, poles, and fence posts with creosote, a preservative that consists of a mixture of numerous chemical compounds derived from coal tar, and No. 6 fuel oil, but not with pentachlorophenol. (Operations at a creosote plant typically include storage facilities for both creosote and fuels; a boiler used to make steam to heat the creosote and aid in application to the wood through usage of heat and pressure; unloading, storage, and transportation of incoming timbers to the creosote application facility; and subsequent storage of treated timber in a drying area. After these processes were completed, the treated timbers would then be shipped to customers. Potential for release of contamination exists throughout the storage, application, and drying processes.) For a time, the Moss facility discharged wastes to settling ponds that discharged to the river. The discharges later ceased when the plant diverted its process water discharge to the Milwaukee sanitary sewerage system. Production at the facility ceased in 1976. In September 1984, the United States Environmental Protection Agency (EPA) placed the Moss-American (Kerr-McGee Oil Co.) site on the Superfund National Priorities List. Site Responsibility The Moss-Amercian site is being addressed under a combination of federal and state actions and by potentially responsible party (PRP) actions under federal and state oversight.
