The Environmental Protection Agency (EPA or the Agency) today revises the regulations for reformulated gasoline in two ways. These changes only apply to reformulated gasoline certified using the Simple Model, which applies until January 1, 1998. First, the maximum allowed level of oxygen in reformulated gasoline is set at 3.2 percent by weight (``wt%''), where a state notifies the Administrator that a limit is needed for various air quality concerns. Second, absent such a state notification, the maximum limit on oxygen content for reformulated gasoline certified using the Simple Model would be that set by the valid range limits of the Simple Model. In addition, the provisions of section 211(f) of the Clean Air Act (``CAA'' or ``the Act'') continue to apply to reformulated as well as other gasolines. These provisions independently set a maximum oxygen content for motor vehicle gasoline.
