Frequent Questions

How much time do the Potentially Responsible Parties (PRPs) have to clean a Superfund site?

The amount of time PRPs have to clean up a Superfund site depends upon the urgency and extent of contamination. The Superfund hazardous waste cleanup process can take anywhere from a few hours to several decades, and there is not a time limit within which all Superfund site cleanups must be completed.

For each hazardous waste site that requires cleanup, EPA officials sign an Action Memorandum for emergency response actions of a Record of Decision (ROD) for long-term cleanups. These decision documents describe the cleanup actions that will be taken and the amount of time it is expected to take. The ROD or Action Memorandum is the blueprint for the site cleanup, and all involved are responsible for holding to its terms.
