Document Description
The SMUD Board of Directors adopted an Initial Study/Mitigated Negative Declaration (IS/MND) (State Clearinghouse No. 2017052041) and approved the El Dorado Cloud Seeding Program Expansion Project (Project) on October 19, 2017. The Project increased the cloud seeding area from 190 square miles to 444 square miles, and expanded the mix of techniques used to disperse silver iodide nuclei. The cloud seeding techniques included a combination of stationary ground-based units, aircraft, and mobile units transported to selected sites. For using aircrafts, the IS/MND only evaluated the use of wing-mounted burn-in-place flare racks that allowed silver iodide flares to be burned in any quantity throughout the flight. Since adoption of the IS/MND, the use of silver iodide ejectable flares as a supplemental method for aerial cloud seeding has been proposed for the Project. As a result, the Addendum discusses only those impacts which have the potential to be affected by the proposed use of ejectable flares. The Addendum does not affect the remainder of the IS/MND and the IS/MND continues to serve as the appropriate document addressing the environmental impacts of the Project pursuant to CEQA.
