* Activities previously authorized under one of the 12 NWPs that have been reissued in 2021 will continue to be authorized until March 18, 2022 provided they meet the terms and conditions of the new NWP and any applicable regional conditions.   If under construction or under contract to construct by this date, these activities would be grandfathered for an additional 12 months.  Previously authorized activities that do not qualify under any of the 12 reissued NWPs must be under construction or under contract to construct prior to March 15, 2021 in order to be grandfathered.  Previously authorized activities that do not meet either circumstance must be reauthorized.

** Activities on tribal lands must be certified by EPA or individual tribes with certifying authority granted by EPA.  Refer to the tribal certification information provided on our website for additional information.

*** Non-oil and gas utility lines previously authorized under NWP 12 must be under construction or under contract to construct in order to be grandfathered.  Such utility line activities that are unable to meet this grandfathering provision may qualify for reauthorization under NWP 57 (electrical/telecom) or NWP 58 (water or other substances).
