Regulatory Programs and Permits

Regulatory (Permits)

Man and woman checking soil conditionsThe 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 and navigation capacity, while allowing reasonable development through fair and balanced decisions.  The Corps evaluates permit applications for essentially all construction activities that occur in the Nation's waters, including wetlands.

Regulatory Guidance Letters (RGLs) were developed by the Corps as a system to organize and track written guidance issued to its field agencies.  RGL’s are normally issued as a result of evolving policy; judicial decisions and changes to the Corps regulations or another agency’s regulations which affect the permit program.  RGL’s are used only to interpret or clarify existing Regulatory Program policy, but do provide mandatory guidance to the Corps district offices.  RGL’s are sequentially numbered and expire on a specified date.  However, unless superseded by specific provisions of subsequently issued regulations or guidance, the content provided in RGL’s generally remains valid after the expiration date.  The Corps incorporates most of the guidance provided by RGL’s whenever it revises its permit regulations.
