The Environmental Emergency Response (EER) Section is the department’s front line of defense against releases of hazardous substances, natural or man-made disasters and threats to homeland security. EER fulfills the department’s duties outlined in legislation commonly known as the Spill Bill. The legislation appears in Missouri's revised statutes: Chapter 260, Sections 260.500 - 260.550. EER's responsibilities include addressing any material released to land, water or atmosphere that may impact the environment and public health.

Duty officers monitor the department's spill line 24/7 on a rotating basis. During normal business hours, duty officers staff the incident command center at the Environmental Services Program in Jefferson City, and after business hours, they answer the spill line from home.

EER's state on-scene coordinators work from six locations in Missouri: Jefferson City, St. Louis, Kansas City, Poplar Bluff, Macon and Springfield. Duty officers dispatch them when environmental emergencies occur. All state on-scene coordinators are certified hazardous material technicians.

EER receives more than 1,500 incident calls annually and responds to more than 300 emergencies involving hazardous substances. Many of those calls stem from tractor trailer accidents. Impact caused by accidents may puncture fuel tanks, discharging fuel to the environment. After an accident, a truck's cargo also may become a cause for concern.

Whether state on-scene coordinators respond to an incident in a metropolitan area or in the country, they stand ready to protect the environment of the state of Missouri.

EER Tracking System

EER uses a database, the Missouri Environmental Emergency Response Tracking System, as a repository for information related to all hazardous substance emergencies and releases.  Details of each spill or incident are entered into the system by the officer on duty at the time of the spill. The database information can be queried as far back as December 1993. It is available on the Internet in a searchable format.

Public Outreach

EER develops working relationships with local, state and federal partners. It is extremely important to share our mission and to understand the roles and responsibilities of other agencies before environmental emergencies occur in their jurisdictions.

It is equally important to educate, inform and interact with the general public, school children and other parties to help them understand their role in protecting the environment and our role in responding to emergencies.
The EER section reaches individuals through:

  • Booths at the Missouri State Fair, Earth Day celebrations, career fairs and other such events
  • Meetings of emergency planning committees and homeland security committees
  • Training sessions
  • Local, regional and statewide exercises.

Upcoming classes, trainings and conferences of interest to first responders
