Discharge of Dredged and Fill Material - 401 Water Quality Certification and Waste Discharge Requirements
Most projects requiring 401 Water Quality Certification fall into two categories:
- Projects involving discharges of dredged or fill material to waters of the United States including wetlands and other water bodies. Such discharges may result from navigational dredging, flood control channelization, levee construction, channel clearing, fill of wetlands for development, or other activities.
These projects involve the removal or placement of soil, sediment, and other materials in or near water bodies and require Corps permits under CWA Section 404. This information sheet concerns this category of activities.
- Projects involving construction of hydroelectric dams, power plants, and other facilities requiring Federal Energy Regulatory Commission (FERC) licenses and projects which must secure a State water rights permit. The State Board reviews these projects for certification.
