401 Water Quality Certification

Clean Water Act section 401 Water Quality Certification (WQC) was requested from all certifying authorities within the Los Angeles District. This includes the states of California and Arizona, tribes with 401 authority, and the USEPA for all other tribal lands. The WQC status of each NWP for state certifying authorities, EPA, and applicable tribal authorities is provided in the District's summary tables for California and Arizona.

Use of any NWPs that are not certified will require individual water quality certification.

Please note that the U.S. Environmental Protection Agency's Clean Water Act Section 401 Certification Rule promulgated on July 13, 2020 has been vacated by the courts and is no longer in effect. WQC has reverted to the 1971 regulations while EPA develops new regulations. Additional information is available at EPA's website:
