The registry is a list of sites containing hazardous waste. By law and regulation, it provides a variety of institutional controls that allow for residual contamination to be left on-site while still protecting human health and the environment. 

Institutional controls:

  • Deed notification of contamination.
  • Annual inspection.
  • Notice to buyer.
  • Change of use review.
  • Notice to the state if property is sold.
  • Deed notice if cleaned up and removed from the registry.
  • Public information about site location.
  • Classification of threat, contaminants and health concerns.
  • Information regarding nearby public and private drinking water wells.
  • Geology of site.

What the registry does: 

  • Notifies the public about property on the registry and its associated hazards.
  • Informs potential buyers about hazards and legal obligations they may undertake if such property is purchased.
  • Protects property buyers from unknowingly purchasing contaminated property.

Sites listed on the registry appear on a publicly available list, and a notice filed with the recorder of deeds documents hazardous waste contamination at the site. Notice regarding contamination must be provided by the seller to potential buyers. The use of a property listed on the registry may not change substantially without review and written approval by the department. Department review ensures protection of human health and the environment by preventing activities that would spread contamination, increase human exposure, increase adverse environmental impacts or make future remediation more difficult. The department makes every effort to provide the most complete registry possible; however, many eligible sites are not yet listed due to pending or ongoing investigations, cleanup negotiations or appeals. Also, unreported facilities or contaminated sites may exist of which the department is unaware.

Registry personnel oversee and coordinate activities at all sites currently listed on the registry. Superfund Remedial Project Managers provide oversight for sites undergoing characterization and/or remediation under Registry consent agreements. When a site owner is willing to remediate a site in order to avoid being listed on the registry, the owner may negotiate a consent agreement, which establishes a schedule and specific responsibilities for the completion of site investigation and remediation by the property owner or responsible party under state oversight.

Each year, pursuant to state law, the department develops, publishes and distributes the Missouri Registry Annual Report

What the registry includes:
  • A site location map.
  • Address.
  • Waste type.
  • Site description.
  • Present property owner.
  • Environmental problems related to the site.
  • Remedial actions at the site.
  • Geologic and hydrogeologic description.
  • Public drinking water advisory and health assessment.
  • National Priorities List (NPL) sites in Missouri.
  • A link to the EPA site summary about each NPL site.
  • Registry cleanup list.
  • Consent Agreement Site list.
  • Health Assessment chemical table.
  • Glossary of health terms.

Within the department and the Missouri Department of Health and Senior Services (DHSS), a Site Assessment Committee can evaluate the sites on the registry and assess classification changes. The Site Assessment Committee can take into account new information about a site or remedial measures taken to reduce potential risk. If conditions at a site have changed over the past fiscal year, the committee may recommend a change in classification that better defines the threat to human health and the environment.

Members of the Site Assessment Committee:

  • The department's Hazardous Waste Program.
  • Water Protection Program.
  • Environmental Services Program.
  • Missouri Geological Survey.
  • Missouri Department of Health and Senior Services. 

The Missouri Registry Annual Report (PUB337) is also available on CD for $3.
