California Environmental Quality Act (CEQA) Documentation

Prior to beginning any of the activities associated with the Tuscan Aquifer Investigation, the Department conducted an Initial Study under the California Environmental Quality Act (CEQA). A Mitigated Negative Declaration was prepared alongside the Initial Study to document the Department’s analysis. Further on this page you will find the links to the Initial Study with the Mitigated Negative Declaration (IS/MND), the appendices to the declaration, the notice of intent (NOI) to adopt the IS/MND, and a field activity map that indicates the locations of project activities.
