Pre-construction Notification Submittal Changes
As of December 5, 2025, the US Army Corps of Engineers’ (USACE) new Regulatory Request System (RRS) became mandatory for submittal of 404 Permit applications. Therefore, the Electronic Preconstruction Notification Application (ePCN) no longer automatically transfers your submittal to USACE.
The Division of Water Resources is still accepting 401 Water Quality Certification application submittals via the ePCN, however applicants who use the ePCN will also have to apply for a 404 permit via the USACE RRS.
