Are wetlands protected under antidegradation rules?
Activities that disturb wetlands, including dredging and filling, are regulated by the US Army Corps of Engineers. If the permitted activity has the potential to impact an Outstanding Iowa Water or an Outstanding National Resource Water, then the Antidegradation rules would require a site-specific review and water quality certification by the Iowa DNR to determine if the activity would degrade the protected waterbody. The DNR would accept public comments and would need to certify that water quality would be protected prior to allowing the permit to be issued .
