2019
On October 1, 2019, the Bureau of Reclamation released a letter to the California Department of Fish and Wildlife that summarized and updated Reclamation's position regarding the Delta Smelt Fall Habitat Action in 2019. On September 25, 2019, in conformance with the National Environmental Policy Act (NEPA), Reclamation released a Finding of No New Significant Impact (FONNSI) and a final Environmental Assessment (EA) that evaluated and disclosed potential environmental impacts associated with implementation of the Delta Smelt Fall Habitat Action in 2019. The EA describes the existing environmental resources in the project area and evaluated the impacts of the No Action and Proposed Action alternatives. On August 5, 2019, a draft EA was released as part of the same process. All of the documents and associated appendices are available at:
https://www.usbr.gov/mp/nepa/nepa_project_details.php?Project_ID=39801
This EA is tiered from the 2015 Long-Term Operations Environmental Impact Statement (LTO EIS) and 2016 Record of Decision. It also incorporates by reference the Delta Smelt Fall Outflow 2017 EA and Finding of No New Significant Impact (FONNSI). Analyses included in this EA are based on the information and analyses included in the LTO EIS, and the Delta Smelt Fall Outflow 2017 EA. The LTO EIS and 2016 ROD are available online at:
https://www.usbr.gov/mp/nepa/nepa_projdetails.cfm?Project_ID=21883
The Delta Smelt Fall Outflow 2017 EA and FONSI are available online at:
