Frequent Questions

If a refiner produces "specified RBOB" for 3.5% oxygenate (for example, 10% vol EtOH) blending, and an oversight program shows that the downstream blender is adding less than 10% EtOH, who is liable for a compliance violation? If there a violation at all

If the downstream oxygenate blender is adding oxygenate in amounts other than that specified by the refiner of the RBOB, the blender would be liable for a violation of the regulations regardless of whether the gasoline meets the downstream standards. In such a case, the RBOB refiner would have to recalculate its batch values for the RBOB to reflect that actual level of blending that occurred (e.g., benzene and toxics emissions performance.)(11/28/94)
