The USACE Los Angeles District has prepared a summary table highlighting important distinctions between the 2017 and 2021 NWPs in terms of expiration dates, regional conditions, and 401 water quality certification status throughout Los Angeles District's Area of Responsibility.

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, 14 individual tribes with 401 authority and the USEPA for all other tribal lands. The WQC status of each NWP for the states of California and Arizona is provided in the District's summary table. This includes the WQC status of the 40 NWPs that are not being reissued at this time and remain in effect under the January 7, 2017 final rule. For WQC information pertaining to NWP activities on tribal lands, please see the "Tribal 401 WQCs" section below.

Use of any NWPs that are not certified will require individual water quality certification pursuant to the U.S. Environmental Protection Agency's Clean Water Act Section 401 Certification Rule, which became effective September 11, 2020. Further information on new procedural requirements established by the 401 Rule can be found in Los Angeles District's Public Notice for the 401 Rule. NWPs that are certified or certified subject to conditions must follow the requirements of the certification issued by the certifying authority (state certifying authority, CA tribal authority, or AZ tribal authority). NWPs for which WQC has been waived do not require WQC from the associated certifying authority.

Tribal 401 WQCs

NWP activities on tribal lands within the boundaries of the Los Angeles District may be subject to additional conditions and other requirements (a map of tribal lands is available here). The USACE Los Angeles District has prepared summary tables that overview the WQC status on tribal lands within the states of California and Arizona.
