Frequent Questions

What does SEMS archive mean?

Archived sites have been removed and archived from the Comprehensive Environmental Response, Compensation and Liability Information System (SEMS) inventory. Archived status indicates that to the best of the EPA's knowledge, Superfund has completed its assessment of the site and has determined that no further steps will be taken to list that site on the National Priorities List (NPL). Archive candidates include:

  • Sites where no contamination was found, or any contamination was removed quickly without requiring placement on the NPL; and
  • Sites where the contamination was not serious enough to warrant Federal Superfund attention.

The archive decision does not necessarily mean that there is no hazard associated with a given site; it only means that based upon available information, the location is not judged to be a potential NPL site.
