IDEM > Environmental Cleanup > RISC: Risk Integrated System of Closure > RISC Technical Guide RISC Technical Guide

This Technical Resource Guidance Document (Technical Guide) was written for use by environmental professionals seeking closure on sites through an Indiana Department of Environmental Management (IDEM) remedial program. This guidance document provides information on how to use the IDEM Risk Integrated System of Closure (RISC) within the authority of IDEM's remediation programs. The intent of the document is to provide (1) a default approach to site closure and (2) a framework for nondefault options if the default approach is not used. The primary goal of RISC is to ensure that risks to human health and the environment are reduced to a negligible level. A companion manual, the RISC User's Guide (User's Guide), offers a broader perspective on programmatic considerations as well as program-specific procedures. The User's Guide should be consulted for program-specific information on how the Technical Guide procedures may be applied.

The RISC Technical Resource Guidance document can be downloaded in its entirety in one large file or each chapter individually.

This final document was released on February 15, 2001.

The RISC User Guide is also available for download.
