The California Environmental Quality Act (CEQA) is a California law (California Public Resources Code section 21000 et seq.) enacted shortly after NEPA, requiring government projects to make Environmental Impact Reports to inform the public and to avoid or mitigate significant environmental impacts. Private projects that require any discretionary government approval (city or otherwise) fall under CEQA's jurisdiction. To comply with CEQA, an entity must first prepare an Initial Study, assessing whether a project may have significant environmental impacts. If so, the agency must prepare an environmental impact report. If not, the agency must prepare a Negative Declaration. If the project would have significant environmental impacts, but those impacts may be mitigated to a level of less than significant, then the agency must prepare a Mitigated Negative Declaration. The act is primarily enforced by the California citizenry through administrative proceedings and in state court.
