Ethanol Blend Dispenser Requirement

Something Missing?

Email the Technical Response Service or call 800-254-6735.

An ethanol retailer selling a blend of at least 9% ethanol by volume must use gasoline storage and dispensing infrastructure that the Iowa Department of Natural Resources and state fire marshal have determined is compatible with the ethanol blend being dispensed. Exceptions may apply.

A gasoline retailer that replaces or converts gasoline storage and dispensing infrastructure to store and dispense a gasoline blend of 15% ethanol by volume (E15) or higher must guarantee the infrastructure is also capable of storing and dispensing E85.
