The California Environmental Policy Council (CEPC) was originally established by the Environmental Protection Permit Reform Act of 1993 (Pub. Resources Code, § 71000 et seq.) to designate a consolidated permit agency for applicants for environmental permits from multiple environmental agencies. In 1999, CEPC functions were expanded to review multimedia evaluations of new motor vehicle fuels. (Health & Saf. Code, § 43830.8.) The California Air Resources Board (CARB) may not adopt any regulation that establishes a motor vehicle fuel specification unless a multimedia evaluation conducted by affected agencies and coordinated by the CARB is reviewed by the CEPC.
Council Members
• The Secretary for Environmental Protection (CEPC Chair)
• The Director of Pesticide Regulation (DPR)
• The Director of Toxic Substances Control (DTSC)
• The Chairperson of the State Air Resources Board (CARB)
• The Chairperson of the State Water Resources Control Board (SWRCB)
• The Director of the Office of Environmental Health Hazard Assessment (OEHHA)
• The Director of the Department of Resources Recycling and Recovery (CalRecycle)
The CEPC is established by, and its Chair and membership statutorily identified under, Public Resources Code section 71017.
Note: Though Section 71017 identifies a membership position for the “Chairperson of the California Integrated Waste Management Board” (CIWMB), in 2010, CalRecycle was established to replace the CIWMB.

Multimedia Evaluation
Health and Safety Code section 43830.8 requires that a multimedia evaluation and peer review be conducted when CARB proposes a regulation that establishes a specification for a motor vehicle fuel. In accordance with the requirements of section 43830.8(g), CalEPA formed the interagency Multimedia Working Group (MMWG) to oversee fuel multimedia evaluations. The MMWG includes representatives from CARB, State Water Board, OEHHA, DTSC, and Office of the State Fire Marshal. The E15 multimedia evaluation includes assessments of potential impacts on air, water, soil, and public health that may result from the production, use, and disposal of the fuels. In the evaluation, CARB staff was responsible for the air quality impact assessment and the overall coordination with the MMWG. State Water Board staff was responsible for the evaluation of surface water and groundwater quality and potential impacts. OEHHA staff was responsible for evaluating potential public health impacts. DTSC staff was responsible for evaluating potentially hazardous waste and soil impacts.
The MMWG prepared a written summary of the E15 multimedia evaluation, including comments from peer reviewers and the MMWG’s response to those comments, as peer review is a required part of the multimedia evaluation process.
The E15 multimedia evaluation that is being reviewed by the CEPC is available on CARB’s website at https://ww2.arb.ca.gov/resources/documents/fuels-multimedia-evaluation-e15. Based on the multimedia evaluation, CARB proposes that the CEPC determine that the proposed E15 regulation will not cause a significant adverse impact on public health or the environment, as provided in section 43830.8.
