CWA 401 Water Quality Certification

Dredge/Fill (401) and Wetlands Program

Welcome to the Certification and Wetlands Program

This program regulates discharges of fill and dredged material under Clean Water Act Section 401 and the Porter-Cologne Water Quality Control Act.

This program protects all waters in its regulatory scope, but has special responsibility for wetlands, riparian areas, and headwaters because these waterbodies have high resource value, are vulnerable to filling, and are not systematically protected by other programs. We are involved with protection of special-status species and regulation of hydromodification impacts. The Program encourages basin-level analysis and protection, because some functions of wetlands, riparian areas, and headwater streams - including pollutant removal, flood water retention, and habitat connectivity - are expressed at the basin or landscape level.

Most projects are regulated by the Regional Water Quality Control Boards (Regional Boards). The State Water Resources Control Board (State Water Board) directly regulates multi-regional projects and supports and coordinates the Program statewide.
