Under the simple model for 1995-1997, refiners and importers are required to meet standards for exhaust benzene, sulfur, olefins and T90 on an annual average basis for conventional gasoline and, under certain conditions, applicable blendstocks as specified in § 80.102. Beginning in 1998, refiners and importers are required to meet standards for exhaust NOx and toxics emissions on an annual average basis.
There are no "per-gallon" requirements for conventional gasoline. The anti-dumping requirements do not preclude the blending of ethanol with finished gasoline or with blendstocks which become gasoline upon the addition of oxygenates.(7/1/94)
