Tertiary butyl alcohol may be blended in amounts permitted under its section 211(f) waiver. There are several oxygenates available other than the two most common, MTBE and ethanol, and these oxygenates may be legally used if blended in the type and amount specified under EPA's "substantially similar" rule and any section 211(f) waiver than may apply. Parties needing further information about the legality of a particular oxygenate should contact the Field Operations and Support Division Fuels Team at (202) 233-9050.(8/29/94)
