401 Certification
|
Section 401 of the Clean Water Act (CWA) requires that a water quality certificate be either issued or denied by the state and/or tribe with jurisdiction before FERC issues a hydropower license. Under the CWA, if a state fails to act on an application within one year, the requirement is waived. Applicants, in order to conduct activities which may result in any discharge into the navigable waters of the United States, must obtain a certification from the State or eligible Indian tribe in whose jurisdiction the discharge originates, that the activity will comply with applicable CWA provisions.

The term can be used differently when referring to the level of agreement required for a particular issue, a settlement agreement, or the decision to use an alternative licensing process (ALP). Participants in individual licensing processes may define what they determine to constitute consensus on particular issues and settlement agreement. For selection of an ALP, FERC's final rule states that "While unanimous views obviously reflect consensus, unanimity is not always essential to a fundamentally consensual approach in a multi-party situation."
