The purpose of this document is to set out for new fuel applicants a set of recommended guidelines regarding how to approach, conduct, and submit a multimedia evaluation. As required by Section 43830.8 California Health and Safety Code (H&SC 43830.8), before adopting new fuel specifications CARB is required to prepare a “multimedia evaluation” and submit it to the CEPC for final review and approval. In general, the State of California needs information that will allow an informed decision as to the relative risk posed by any newly proposed fuel to the State’s resources, human health and the environment. New fuels or potential fuel additives must be evaluated not only with regard to engine performance and emission requirements but also with consideration of health and environmental criteria involving airborne toxics and associated health risks, ozone formation potential, hazardous waste generation and management, and surface and groundwater contamination resulting from production, distribution, and use.
The multimedia evaluation is needed to provide the best available scientific information to determine any “significant adverse impacts” to human health and the environment. The multiple environmental media that should be evaluated include air, water (surface water and groundwater), and soil. Once completed, the proposed regulation and the multimedia evaluation need to be submitted to the CEPC for review and final approval.
