On March 27, 2006, EPA and the U.S. Army Corps of Engineers (the Corps) announced proposed revisions to regulations governing compensatory mitigation for authorized impacts to wetlands, streams, and other waters of the U.S. under Section 404 of the Clean Water Act. These revisions are designed to improve the effectiveness of compensatory mitigation at replacing lost aquatic resource functions and area, expand public participation in compensatory mitigation decision-making, and increase the efficiency and predictability of the process of proposing compensatory mitigation and approving new mitigation banks. These revisions are also designed to compliment EPA's and the Corps' ongoing efforts to implement the 2002 National Wetlands Mitigation Action Plan.
