The New Mexico Environment Department (NMED) issued a statement in late May 2022 that Individual Water Quality Certification (WQC) under Section 401 of the Clean Water Act (CWA) will be required for all projects seeking CWA Section 404 authorization using one of 13 Nationwide Permits (NWPs) (including some of the most widely used NWPs for energy, development, and transmission projects). The U.S. Army Corps of Engineers (USACE) Albuquerque District released a Special Public Notice outlining the individual WQC process, including a pre-filing meeting, requirements for applications, and review timelines.


For any project activities that may result in a discharge into waters of the U.S., Individual WQC is required with the Certifying Authority, including a pre-filing meeting request, for activities covered by the 13 NWPs, regardless of the impacts threshold (acres of proposed dredge or fill material). In turn, preconstruction notification to the USACE is required for compliance with CWA Section 404. These new regulations could lengthen the time needed to complete environmental permitting.
