Kansas Oxide Site

Site Background

The Kansas Oxide facility, a two-section building with an attached outbuilding, is located at 603 Sunshine Road, Fairfax District, Kansas City, Kansas. The Kansas Oxide site includes areas on the exterior of the Kansas Oxide facility and portions of the adjacent Central Solutions facility, but not the railroad property to the west.

The Kansas Oxide facility produced powdered lead oxide for battery components from around 1980 until December 2003. This process involved melting lead ingots in Barton pots where the molten lead was reacted with air to produce lead oxide dust. This lead dust was then collected with a cyclone and bag-house filtration system. Fugitive dust releases have resulted in contamination of nearby surface and shallow subsurface soils and the roof of the adjacent Central Solutions building, where the dust washed into the gutters and onto the ground.

A number of environmental investigations since 1993 have identified areas with lead contamination as high as 300,000 milligrams per kilogram (mg/kg). This exceeds the Risk-based Standards for Kansas (RSK) (October 2012) residential Tier 2 screening level for lead of 400 mg/Kg.

Two related Consent Agreement and Final Orders (CAFOs), Case Numbers 10-E-0038 and 10-E-0082, between the Kansas Department of Health and Environment (KDHE) and Metals and Additives Corporation (M&A) were signed July 6, 2010. The CAFOs require M&A to investigate and characterize the site, develop remediation plans, and implement these plans with KDHE oversight.

M&A submitted the Removal Site Evaluation report in October 2012, and, after several iterations, KDHE approved the report April 4, 2013. The Revised Removal Site Evaluation Report (April 2013) notes three soil samples collected from near the Kansas Oxide ventilation exhaust ductwork exceeded the RSK residential screening criteria and range from between 3,300 mg/kg and 20,000 mg/kg.

Based on the data compiled during the various phases of investigation, lead contamination is limited to the top two feet of soil in a grassy area on the southern border of the Kansas Oxide facility, adjacent to and north of the Central Solutions building. The remedial plan consists of returning the site to unrestricted future use by removing lead-contaminated soil exceeding Tier 2 residential RSK levels, and back-filling with clean soil.
