401 & Buffer Transportation Permitting

The Transportation Permitting Branch works with the general public, towns, cities, and the N.C. Department of Transportation (NCDOT) to assist with the planning, permitting and design of transportation projects. Their goal is to provide needed infrastructure for citizens while ensuring the continued protection of North Carolina's water quality.

The Branch's responsibilities include the review of 401 certification applications for transportation projects and wetland and stream mitigation plans, as well as conducting relevant site visits. Branch staff represent the Division of Water Resources on the 404/NEPA Merger Team. The Branch also includes staff that are associated with the Headwater Stream Spatial Dataset project.

On Thursday April 7, 2022 the Environmental Protection Agency's "Clean Water Act Section 401 Certification Rule" ("Federal Rule") was reinstated to its previous version which originally became effective on September 11, 2020. In accordance with 40 C.F.R. Section 121.4(a) "At least 30 days prior to submitting a certification request, the project proponent shall request a pre-filing meeting with the certifying agency". In accordance with 40 C.F.R Section 121.5(b)(7), and (c)(5) all certification requests shall include documentation that a prefiling meeting request was submitted to the certifying authority at least 30 days prior to submitting the certification request. Please refer to the Federal Rule for more information. To send a pre-filing request please submit an email request by clicking 401PreFile
