Background:

The ARB is authorized to adopt standards, rules and regulations to achieve the maximum degree of emission reduction possible from vehicular and other mobile sources in order to accomplish the attainment of the state ambient air quality standards at the earliest practicable date. The Health and Safety Code directed the Board, no later than January 1, 1992, to take whatever actions are necessary, cost-effective and technologically feasible in order to achieve by December 31, 2000, a reduction in reactive organic gases of at least 55 percent and at least a 15 percent reduction in the emissions of oxides of nitrogen from motor vehicles, and the maximum feasible reductions in particulate matter, carbon monoxide, and toxic air contaminants from vehicular sources. The ARB's fuels effort is made up of several components which broadly fall into two categories: (1) adopting and enforcing fuel specifications, and (2) controlling emissions from marketing and distributing fuels in California. The ARB also has developed a wide variety of general information about California refineries. For example, the ARB has compiled information on California refinery emergency response and outreach programs and has developed an assessment of refineries emissions related to the production of CaRFG2. ARB staff has also completed an assessment of air district civil penalties for violations air pollution control regulations at refineries, as well as, provided other information and links on California refineries.
