Phase I Environmental Site Assessment Spotlight: HREC

July 6th, 2016

One of the major changes to the Phase I Environmental Site Assessment ASTM standard (E1527-13) is the enhanced definition of a REC (Recognized Environmental Condition).  ASTM added the term CREC (Controlled REC), in addition to the previously defined REC and HREC (Historical REC).

An HREC property is one that was previously deemed to have potential or actual contamination, but has since undergone remediation that meets current standards of cleanup.  An HREC site is not subject to any land use restrictions.

Case Study

Gabriel was conducting a Phase I in Chicago of a former machine IEPA-logoshop. The site was identified on the regulatory database search as an SRP (Site Remediation Program) site.  SRP is a voluntary cleanup program run by the Illinois EPA.  The IEPA is authorized to issue No Further Remediation (NFR) letters to the Remedial Applicants who have successfully demonstrated, through proper investigation and possible remedial action, that environmental conditions at their remediation site do not present a significant risk to human health or the environment.

This site received an NFR letter with no use restrictions or engineered barriers required.  Since the site clean-up, the property has been unoccupied and no longer has any hazardous substances on the premises.  Therefore, the previous contamination caused by past operations of the occupant represent an HREC for the site.

If you have questions about how Gabriel determines if an environmental condition is an HREC, contact Natalie Neuman, Group Leader Assessment Services, at 773-486-2123 or nneuman{at}gabenv.com.
