The trial court properly denied plaintiff's petition for writ of mandate challenging defendant-water districts' determination that certain interim renewal contracts with the United States Bureau of Reclamation were exempt from the California Environmental Quality Act (CEQA) and contending that defendant should have undertaken a full environmental review, where matters contemplated in the interim renewal contracts were exempt from CEQA, including under the statutory exemption for ongoing pre-CEQA projects and the categorical exemption for the continued operation of existing facilities at the same level of use.
