24-Hour EER Spill Line

Under the Missouri Spill Bill, responsible parties or spillers are required to report hazardous substances releases to the department's 24-hour Environmental Emergency Response Spill Line at 573-634-2436, or the National Response Center at 800-424-8802. Duty officers staff the department's spill line 24 hours per day, seven days per week. The departments spill line provides a single answering point for local and state agencies to request state-level assistance for emergencies, serious accidents or incidents, or for reporting hazardous materials and petroleum spills. The duty officers:

  • Provide technical assistance regarding necessary cleanup actions and chemicals.
  • Work with the responsible party or spiller to make sure proper cleanup is completed. 
  • Work to make sure any impact to the public health and environment is minimized.
  • Notify various agencies.
  • Determine if an on-site response is needed by program staff.

The duty officer enters the details of each spill or incident into the department's Environmental Emergency Response Tracking Systems. The systems are a repository for information related to all hazardous substance emergencies and releases as far back as December 1993.

*If you witness a situation that does not pose an immediate threat to public health or the environment, but still threatens the environment, such as a trash dump or discarded waste tires in a stream, you can report your environmental concern either over the phone to the regional office in your area or online using our Report an Environmental Concern or Submit a Question form.
