AMENDMENTS TO THE CALIFORNIA
REFORMULATED GASOLINE REGULATIONS
EFFECTIVE SEPTEMBER 21, 1998


The purpose of this advisory is to inform all producers, importers, blenders, distributors, haulers and retailers of gasoline in California of amendments to Title 13, California Code of Regulations (CCR), sections 2260-2262.7. The amendments were adopted by the Air Resources Board (ARB) at an August 27, 1998 hearing and went into effect on September 21, 1998.

Section 2261(e) has been added to exempt gasoline used only for racing vehicles from the California Reformulated Gasoline Regulations, and from Section 2253.4 (Lead/Phosphorous in Gasoline) and Section 2254 (Manganese Additive Content). This confirms the ARB's longstanding interpretation of its fuels regulations (See Health and Safety Code Section 43001Exemptions). Section 2260(a)(29.5) has been added to define racing vehicles.

Sections 2262.1(a)(2)(A)and 2262.1(b)(2)(A) have been amended to reflect the division of the Southeast Desert Air Basin into the Mojave Desert Air Basin and the Salton Sea Air Basin.

Section 2261.1(c)(4) has been added to clarify the "pre-season" Reid vapor pressure (RVP) limit that applies to gasoline when it is supplied during March from refineries and import facilities in the South Coast Air Basin, Ventura County, and San Diego County. Gasoline that is produced in California and is shipped by marine vessel to a terminal in any of the above areas will be treated as having been imported at the terminal, for purposes of the March RVP limit only. Any such gasoline that is subsequently supplied from the terminal in March will at that time be subject to the RVP standard of 7.0 psi, just as it would if the gasoline had been shipped to the terminal from out of state.

Sections 2262.2, 2262.3, 2262.4, 2262.6 and 2262.7 have been amended to clarify the averaging provisions in the standards for Sulfur, Benzene, Olefin content, Distillation Temperatures, and Aromatic Hydrocarbon content of California gasoline.

Section 2262.5(e)(2) has been added to provide a grace period during the start of a mandatory wintertime oxygen season for service stations with infrequent deliveries. This provision is similar to the grace period provided in section 2262.1(c)(3) for the start of the RVP season.

Section 2262.5 has been amended to eliminate the state prohibition of winter gasoline containing less than 1.8 percent by weight oxygen in major portions of the state when the refiner uses the California Predictive Model. However, this wintertime prohibition remains in effect in the Los Angeles, Ventura, Orange, Riverside, San Bernardino and Imperial counties. Additionally, until January 31, 2000, gasoline sold in Fresno and Madera Counties and the Lake Tahoe Air Basin is required to meet the wintertime oxygen standard.
