*UPDATE: NOVEMBER 2021*  Due to the decision of the United States District Court for the Northern District of California on October 21, 2021 to remand EPA’s 2020 401 WQC rule with vacatur, the Corps of Engineers is not finalizing permit decisions that rely on a 401 WQC or waiver under EPA’s 2020 rule at this time.  The Corps is working to provide more refined guidance that provides a way forward that allows us to finalize permit decisions.”

Regulatory (Permits)

Welcome to the Rock Island District Regulatory Branch Home Page. We are located in the Clock Tower Building on Arsenal Island in Rock Island, Illinois. We have Regulatory jurisdiction over most of the state of Iowa, approximately 2/3 of the state of Illinois, and the northeastern portion of the state of Missouri.

The Department of the Army Regulatory Program is one of the oldest in the federal government. Initially it served a fairly simple, straightforward purpose: to protect and maintain the navigable capacity of the nation's waters. Time, changing public needs, evolving policy, case law, and new statutory mandates have changed the complexion of the program, adding to its breadth, complexity, and authority.

The Regulatory Program is committed to protecting the Nation's aquatic resources, while allowing reasonable development through fair, flexible and balanced permit decisions. The Corps evaluates permit applications for essentially all construction activities that occur in the Nation's waters, including wetlands.
