Why does the Corps of Engineers regulate work in wetlands?
A. The Corps has been involved in regulating activities by others in navigable waterways through the granting of permits since passage of the Rivers & Harbors Act (Section 10) of 1899. At first, this program was meant to prevent obstructions to navigation, although an early 20th century law gave us regulatory authority over the dumping of trash and sewage. Passage of the Clean Water Act (Section 404) in 1972 greatly broadened this role by giving the Corps authority over dredging and filling in the “waters of the United States,” including many wetlands.
