NOTICE OF INTENT TO ADOPT A MITIGATED NEGATIVE DECLARATION FOR THE DON PEDRO HYDROELECTRIC PROJECT AND THE LA GRANGE HYDROELECTRIC PROJECT FERC LICENSING Turlock Irrigation District (TID) and Modesto Irrigation District (MID), collectively referred to as "the Districts," have prepared a California Environmental Quality Act (CEQA) Supplemental Analysis in an Initial Study/Mitigated Negative Declaration (IS/MND) format, to provide the public, responsible agencies, and trustee agencies with information about the potential environmental effects of the Districts accepting from the Federal Energy Regulatory Commission (FERC) a new license for the Don Pedro Hydroelectric Project (Don Pedro Project), FERC Project No. 299 and an original license for the La Grange Hydroelectric Project (La Grange Project), FERC Project No. 14581. The Districts own and operate the Don Pedro Project, and TID separately operates and maintains hydropower facilities at the La Grange Project. The Districts propose to renew the existing FERC license for hydropower facilities associated with the Don Pedro Project and to obtain an original FERC license for hydropower facilities related to the La Grange Project. The Proposed Project consists of the acceptance and implementation of the new FERC licenses and continued operation and maintenance of the Projects pursuant to the terms and conditions contained in the new licenses. The Draft CEQA Supplemental Analysis relies on the Final Environmental Impact Statement (FEIS) prepared by FERC in July 2020. The Draft CEQA Supplemental Analysis IS/MND found that implementation of the Proposed Project may result in potentially significant environmental impacts to: biological resources; geology and soils; and tribal cultural resources. However, with the implementation of mitigation measures, any potentially significant environmental impacts of the Proposed Project would be reduced to less than significant levels as described in the Draft CEQA Supplemental Analysis IS/MND. The Draft CEQA Supplemental Analysis IS/MND is being circulated for public review and comment for a 30-day period starting on June 27, 2025 through July 27, 2025. Comments on the Draft CEQA Supplemental Analysis IS/MND must be received in writing via email or U.S. mail to the contact listed below by 5:00pm on July 27, 2025. For emailed comments, please include the project title in the subject line and include the commenter's name and U.S. Postal Service mailing address. Michael Cooke, Turlock Irrigation District, 333 East Canal Drive, Turlock, CA 95381. micooke@tid.org During the 30-day public review period, the Draft CEQA Supplemental Analysis IS/MND will be available for review on the CEQAnet web portal at: https://ceqanet.lci.ca.gov/; on the Don Pedro Relicensing webpage at https://donpedro-relicensing.com/; and the La Grange Licensing webpage at https://lagrange-licensing.com/ IPL0249709 Jun 27 2025
