The 2012 Nationwide permits went into effect March 19, 2012.   They will expire March 18, 2017.  States and tribes (including tribes where EPA maintains 401 certification authority) issue 401 certification of the nationwide permits every five years to ensure that they are in compliance with state/tribal water quality standards and other requirements. Under Section 401 of the Clean Water Act states and tribes  have the ability to certify, deny, condition or waive nationwide permits.  Below is a list of 401 certifications issued for the 2012 natiionwide permits.  In some states nationwide permits have been wholly or partially revoked and replaced with a general permit.  These are also issued for 5 years, but start and end on dates different from the nationwide permits.  These are included in the list below as well.  More information about Section 401 Certification can be found in the 401 certification webpages of the Association of State Wetland Managers website here.
