Clean Water Act - Definition of "Waters of US"
The U.S. Environmental Protection Agency (EPA) and U.S. Army Corps of Engineers (ACOE) have developed draft guidance on determining which waterways, water bodies, or wetlands are protected by the Clean Water Act. This draft guidance will strengthen protections for small streams and wetlands by providing clarification that small streams and intermittent streams are protected under the Clean Water Act if they have a physical, chemical, or biological connection to larger bodies of water and could affect their integrity.

The definition of “traditional navigable waters” has also been changed to include a wider range of circumstances. Also, interstate waters crossing state borders will be protected.
