Superfund Redevelopment Initiative

Sitewide Ready for Anticipated Use (SWRAU) Superfund Sites - Retractions

The determination that a site is SWRAU is based on the information available at the time the determination is made. That determination may revert if site conditions change, or if new or additional information is discovered regarding the contamination at the site. If after a site has been designated as SWRAU, EPA becomes aware that any of the requirements are no longer met, then the site can be retracted. The site can be re-designated as SWRAU only when the requirements outlined in the guidance are met.
