This act is the oldest federal environmental law in the United
States. The Act makes it a misdemeanor to discharge refuse matter of any kind into the navigable waters of the United States without a
permit; this specific provision is known as the Refuse Act. The Rivers and
Harbors Act also makes it a misdemeanor to excavate, fill, or
alter the course, condition, or capacity of any port, harbor, channel,
or other areas within the reach of the Act without a permit. Although
many activities covered by the Rivers and Harbors Act are
regulated under the Clean Water Act, the 1899 Act retains independent
vitality. The Rivers and Harbors Act is administered by the U.S. Army Corps of Engineers. Related acts were also passed in 1913 and 1938. Congress passed an act of the same name in 1882, and overrode a veto by President Arthur.
