EPA Region 1 Preliminary Remediation Goals for Post-Remedy Ecological Exposure

EPA Region 1 has released draft Preliminary Remediation Goals (PRGs) specifically developed for post-remedy ecological exposure assessment scenarios. These draft guidelines address how ecological risk should be evaluated after remediation measures have been implemented at contaminated sites, establishing new criteria for determining whether residual contamination poses acceptable ecological risk following cleanup actions.

Parties involved in Superfund remediation or other EPA cleanup programs in the New England region should review these draft PRGs and provide feedback through the regulations.gov docket. The document may affect how post-remedy ecological risk is assessed and documented for regulatory closure at contaminated sites.
