Under CEQA, who prepares the Environmental Impact Report (EIR)?

The preparation of the Environmental Impact Report (EIR) under the California Environmental Quality Act (CEQA) is the responsibility of the Lead Agency. The Lead Agency is typically the governmental body or agency that has the primary responsibility for approving or carrying out the project that is being evaluated. This agency coordinates the environmental review process to ensure compliance with CEQA regulations.

The Lead Agency conducts the necessary investigations, gathers data, and prepares the EIR to identify potential environmental impacts associated with the proposed project and to explore possible mitigation measures. This report must provide an analysis of the potential environmental effects of the project, alternatives to the project, and any measures to mitigate adverse impacts.

Other entities involved in the environmental review process, such as Responsible Agencies or local government councils, might comment on the EIR or share responsibilities, but they do not prepare the document itself. The Lead Agency has the expertise and authority to oversee the specific project being reviewed, making it the key body in terms of EIR preparation.
