IDEM released Version 1.2 of the tool on May 1, 2009 as a means of providing access to Default Closure Levels located in Appendix 1 of the RISC Technical Guidance Document.

The RISC Default Closure Tool works with the following versions of Microsoft Office: Office 2000, Office XP, and Office 2003. The RISC Default Closure Tool does not appear to work with any version of Office for Mac.
