Hazardous Waste Treatment, Storage and Disposal (TSD) Cleanup Sites

According to applicable state and federal hazardous waste laws and regulations, all hazardous waste treatment, storage and disposal facilities are required to investigate and clean up hazardous waste releases to the environment from their facility resulting from present and past hazardous waste handling practices. This includes hazardous waste released by previous facility owners. These cleanup activities, known as corrective action, reduce risks to human health and the environment. Both the department and U.S. Environmental Protection Agency (EPA) are responsible for regulating and overseeing investigation and corrective action activities at facilities that either currently treat, store (for more than 90 days) or dispose hazardous waste in Missouri, or did so in the past. The information below pertains to facilities that fall under the federal Resource Conservation and Recovery Act (RCRA) and Missouri's RCRA-equivalent hazardous waste program. For information about investigation or cleanup activities at uncontrolled or abandoned hazardous waste contaminated sites, visit Superfund. For information about other properties in Missouri undergoing a specific type of investigation or cleanup, visit Investigations and Cleanups. 

The department and EPA regulate investigation and corrective action activities under several types of legally enforceable instruments, such as hazardous waste permit(s), administrative orders, court orders and other regulatory agreements. The agency that issues the legal instrument is the agency responsible for overseeing the activities at that facility. For some facilities where EPA has oversight responsibility, the department helps as the technical lead. Together the agencies review the facility investigation, monitoring and cleanup work plans and reports to make sure they comply with applicable state and federal laws and standards and ensure the activities are conducted in a way that protects human health and the environment.

Listed below are facilities where investigation or cleanup activities (corrective action) are being performed and the department is providing oversight or is technical lead. Also listed are facilities where closure activities are complete in a specific area of the property, but oversight is needed for monitoring and maintenance activities (post-closure activities) in areas where hazardous waste remained in place after closure, such as hazardous waste landfills or surface impoundments. You can “click” on the facility’s name for more information about the facility and the regulatory agreement(s) the facility is regulated under. These facilities are also included in the department's Environmental Site Tracking and Research Tool (E-Start) interactive map, which allows users to access information about site investigations and cleanups and certain regulated sites within a specific community or area. EPA’s Envirofacts database includes similar information, but for facilities EPA is providing oversight and facilities that no longer require oversight. Envirofacts provides information about environmental activities that may affect air, water or land anywhere in the United States.

You may call or write the department to have your name placed on the mailing list for any facility listed below. By doing this, you will receive written notice from the department or the facility regarding any major permitting and cleanup activities for that facility. If you have questions about a specific facility, or would like your name added to a facility mailing list, please contact the department’s Waste Management Program.
