DWR Submits the Delta Conveyance Project Revised Certification of Consistency on Remanded Items

From the Department of Water Resources:

DWR submitted the Delta Conveyance Project Revised Certification of Consistency with the Delta Plan on Remanded Items on July 24, 2026. The Council’s determination on April 23, 2026, dismissed or denied the vast majority of appeals. For two policy areas, the Council directed a limited remand to DWR. Remands are a standard part of the Delta Reform Act’s Certification of Consistency and appeals process and provide an opportunity to supplement or clarify portions of the record to address the findings in the remand.

This revised certification demonstrates how, for Delta Plan Policy ER P5, DWR fully considered and avoids or mitigates the potential for DCP facilities to improve habitat conditions for the nonnative invasive golden mussel; and how, for Delta Plan Policy DP P2, DWR considered and avoided or reduced conflicts between the siting of the Delta Conveyance Project’s Twin Cities Complex and Sac Sewer’s Harvest Water when feasible. With respect to the remanded items, DWR has determined that the covered action is consistent with ER P5 and DP P2.

According to Delta Stewardship Council regulations, materials relevant to this certification will be posted on their website (https://coveredactions.deltacouncil.ca.gov), if the Certification is appealed, an appeal hearing will be held by the Council followed by the issuance of a determination on the appeal.
