Registration and Health Effects Testing
The Clean Air Act provides EPA with the authority to regulate fuels and fuel additives in order to reduce the risk to public health from exposure to their emissions. The regulations at 40 CFR Part 79 (from the U.S. Government Printing Office) require that each manufacturer or importer of gasoline, diesel fuel, or a fuel additive, have its product registered by EPA prior to its introduction into commerce. Registration involves providing a chemical description of the product and certain technical, marketing and health-effects information. This allows EPA to identify the likely combustion and evaporative emissions. In certain cases, health-effects testing is required for a product to maintain its registration or before a new product can be registered. EPA uses this information to identify products whose emissions may pose an unreasonable risk to public health, warranting further investigation and/or regulation.

- Regulation of Fuels and Fuel Additives: Revised Definition of Substantially Similar Rule for Alaska (published April 25, 2008)
Discussions with an Alaskan refiner have highlighted the need for an amendment to the substantially similar provision of Section 211(f) of the Clean Air Act for unleaded gasoline to improve cold starting of vehicles in Alaska during the winter months. Currently, manufacturers of gasoline for Alaska may not use a temperature below 41 degrees Celsius when testing the vapor-liquid (V/L) ratio of the fuel and still be within the current definition of “substantially similar.” This amendment will allow manufacturers producing unleaded gasoline for use only in Alaska during the winter months to use a minimum test temperature of 35 degrees Celsius when testing for a maximum V/L ratio of 20 instead of requiring a V/L test temperature of 41 degrees Celsius.
