Section 404 of the Clean Water Act

Compensatory Mitigation Rule Familiarization Workshops under CWA Section 404

This page provides training and information regarding the 2008 Clean Water Act Section 404 Final Compensatory Mitigation Rule.

EPA and the U.S. Army Corps of Engineers (the Corps) published a new rule to clarify how to provide compensatory mitigation for unavoidable impacts to the nation’s wetlands and streams on April 10, 2008. The rule promotes greater consistency, predictability and ecological success of mitigation projects under the Clean Water Act.

Between August 2008 and January 2009, EPA and the Corps conducted familiarization workshops on the new rule in Atlanta, GA; Denver, CO; Seattle, WA; Baltimore, MD; Oakland, CA; and Dallas, TX. Organized below are the presentations and other training resources discussed in these workshops.
