Whenever there is a significant release from a site deleted from the NPL, the deleted site may be restored to the NPL without application of the hazard ranking system. Deletion of a site from the NPL does not affect responsible Start Printed Page 49482party liability in the unlikely event that future conditions warrant further actions.
