The Moss-American Kerr-McGee Oil Co. site is located in the northwestern section of Milwaukee, Wisconsin. The eighty-eight acre site includes the former location of the Moss-American wood preserving facility, several miles of the Little Menomonee River, a portion of which flows through the eastern half of the site, and adjacent flood plain soils. Approximately 23 acres of the site are owned by the Union Pacific Railroad, and are used as a loading/unloading and storage area for automobiles and other light vehicle transport.
In 1921, the T.J. Moss Tie Company established a wood preserving facility west of the Little Menomonee River. The plant preserved railroad ties, poles and fence posts with creosote, a mixture of numerous chemical compounds, derived from coal tar. Number 6 fuel oil was also used at the site. Kerr-McGee purchased the facility in 1963 and changed the facility's name to Moss-American. The name was changed again in 1974 to Kerr-McGee Chemical Corporation - Forest Products Division. In 1998, the name of this company changed to Kerr-McGee Chemical, LLC (KMC).
From 1921 to 1971, the facility discharged wastes to settling ponds that ultimately discharged to the Little Menomonee River. These discharges ceased when the plant diverted its process water discharge to the Milwaukee sanitary sewerage system. Production at the facility ceased in 1976.
A Record of Decision (ROD) was issued in September 1990. In December 1991, the United States lodged a Consent Decree with the Federal District Court for the Eastern District of Wisconsin in Milwaukee. The Consent Decree, which was signed by U.S. Environmental Protection Agency (EPA), the State of Wisconsin and KMC, calls for implementation of the Remedial Design and Remedial Action (RD/RA) by KMC as set forth in the ROD. The County of Milwaukee filed objections to the Consent Decree and sought to intervene in the proceeding in 1992. EPA responded to the comments and objections in its 1993 Motion to Enter. The County withdrew its objections in February 1996, after reaching an agreement with EPA on past costs. The decree was entered by the Court in March 1996. A ROD Amendment was issued in September 1998.
This Record of Decision (ROD) Amendment replaces the biodegradation treatment system with low temperature thermal desorption. The ROD Amendment allows for the utilization of new cleanup standards for the portion of the site referred to as the "former wood preserving facility" owned by the Union Pacific Railroad and Milwaukee County, provided certain conditions are met. The ROD Amendment recognizes that it may be appropriate to adopt industrial or recreational exposure scenarios for site users exposed to contaminants of concern in surface soils. If appropriate land use restrictions are obtained, then Union Pacific site property and upland areas of Milwaukee County site property can use the industrial soil cleanup standards established in Wisconsin Administrative Code NR 720 for direct contact and for the protection of groundwater. For Milwaukee County property which is part of the former wood preserving facility and which is located in the floodplain of the Little Menomonee River, a recreational exposure scenario may be appropriate if deed restrictions are signed and recorded which limit the use of the property to recreational uses. If this type of land use restriction is effectuated, then soil cleanup standards established under Chapter NR 720, for recreational land use can be utilized. Control measures attendant to appropriate soil erosion and runoff protection shall also be employed so that contaminants associated with those soils do not pose an undue threat to sediment quality in the nearby Little Menomonee River.
Depending on the level of soil treatment provided, a clay cap topped with a suitable frost-protection soil layer or a simple soil cover may be used to replace the soil cover originally selected. A new disposal unit will be established pursuant to Corrective Action Management Unit (CAMU) requirements under Wisconsin Chapter NR 636. CAMU allows consolidation and placement of certain hazardous remediation wastes without triggering new disposal events which would otherwise require application of land disposal requirements, and liner and leachate collection systems, provided that the activity is protective of human health and the environment.
