Section 401 Removal/Fill Certification

Current News

401 Water Quality Certification Public Notices issued for the Jordon Cove Energy Project and the Oregon LNG project.

Program Overview

Section 401 of the federal Clean Water Act requires that any federal license or permit to conduct an activity that may result in a discharge to waters of the United States must first receive a water quality certification (WQC) from the state in which the activity will occur. In Oregon, DEQ is the agency responsible for issuing this certification.

Section 401 of the Clean Water Act authorizes DEQ to ensure that activities will meet water quality standards established by the state under the Clean Water Act. By ensuring a project does not degrade water quality, Oregon’s waters remain safe for a wide range of uses, such as drinking water, recreation, fish habitat, aquatic life, and irrigation.

DEQ 401 program staff evaluate project proposals for potential impacts to water quality and beneficial uses.

A proposal to remove material from, or place fill into, waters requires a Joint Permit Application to the US Army Corps of Engineers and the Department of State Lands. DEQs 401 Water Quality Certification process is triggered when USACE makes a determination that an application requires a 404 permit. Federal permits cannot be issued without a 401 WQC from DEQ.
