Beginning in 1996, IDEM has published several risk-based screening and closure level tables. This page provides links to the various tables, usually in both Adobe Acrobat and Excel versions.

IDEM issued the 2012 Screening Level Table in conjunction with the Remediation Closure Guide on March 22, 2012. The six-month transition period ends September 22, 2012. See Section 1.4 of the Remediation Program Guide for additional information on transition policies.
