Schedule for Three-year Update Reports for Engineering Reviews (ERs)

  • Updated Engineering Reviews for Renewable Fuel and Foreign Ethanol Producers

All producers of renewable fuel and foreign ethanol producers are required to submit an independent third-party Engineering Review (ER) report at registration and an updated ER report by January 31 of every third calendar year thereafter. To help provide clarity, the EPA has developed a list of registered renewable fuel and foreign ethanol facilities and identified when their updated 3-year ER reports are due. These due dates are based on the best data available to the EPA.

THINK YOUR DUE DATE IS INCORRECT? A facility on this list should contact the Fuels Program Helpdesk if it has documentation showing that its 3-year ER report is scheduled for a different date than what is posted on the list. Documentation could include an EPA-generated registration verification with a date stamp, EPA correspondence to the facility denoting a different 3-year ER report due date, or other documentation deemed acceptable by EPA.
