The U.S. EPA and the U.S. Army Corps of Engineers have developed draft guidance for determining whether a waterway, water body, or wetland is protected by the Clean Water Act. This guidance would replace previous guidance to reaffirm protection for critical waters. It also will provide guidelines for determining which water bodies are protected by the Clean Water Act. The draft guidance will be open for 60 days of public comment to allow all stakeholders to provide input and feedback before it is finalized.
