In order to ensure that federal activities will not violate state water quality standards, the Clean Water Act gives states, some tribes, some interstate agencies and EPA (sometimes) the authority to veto or place conditions on activities requiring a federal license or permit that may result in a discharge (CWA, Section 401(a)(1)). If your state takes full advantage of this authority, known as “water quality certification,” citizens can get involved to protect and restore water quality and uses around and downstream from federally permitted activities. In this lesson, you'll learn more about how to use 401 certifications to protect your river.
