CALIFORNIA AIR RESOURCES BOARD State Building Auditorium, Room 1138 107 South Broadway Los Angeles, CA September 28, 1990 8:30 a.m. AGENDA Page No. 90-15-1 Public Hearing to Consider the Adoption of 001 and Amendments to Regulations Regarding Reformulated Gasoline: Phase I Gasoline Specifications. ITEM NO.: 90-15-1 Public Hearing to Consider the Adoption of and Amendments to Regulations Regarding Reformulated Gasoline: Phase I Gasoline Specifications. RECOMMENDATION The staff recommends that the Air Resources Board (ARB) adopt a new regulation and amend existing regulations as proposed by staff to limit the Reid vapor pressure (RVP) of gasoline, require the use of deposit control additives, and eliminate leaded gasoline. DISCUSSION Background The California Clean Air Act (CCAA) requires the ARB to achieve the maximum degree of emissions reductions from motor vehicles in order to meet the state ambient air quality standards by the earliest practicable date. The ARB is also required to take action to reduce emissions of reactive organic gases by 55 percent and oxides of nitrogen by 15 percent from motor vehicles by December 31, 2000. In order to meet these goals, the ARB staff designed a comprehensive program to reduce emissions from motor vehicles. One element of the program is a low emission/clean fuels proposal which would require the phase-in of vehicles meeting stringent exhaust emission standards. The proposal may require the use of advanced vehicle control technology and the use of cleaner burning fuels. Another element of the program is to require new gasoline specifications, which would reduce emissions from the existing fleet and will assist automakers in meeting more stringent emission standards in the future. The ARB staff divided the reformulated gasoline specifications into two phases. Phase 1 reformulated gasoline specifications, the subject of this proposal, are those that can be implemented in the near future at a reasonable cost and for which adequate data exists to document the expected emissions reductions. Specifications for Phase 2 reformulated gasoline, which will be proposed in the fall of 1991, will be a more comprehensive set of specifications for a "reformulated" or cleaner gasoline to be effective in the 1996 timeframe.
