Recent Updates to Fuels Reporting
May 2026
EPA has updated EMTS functionality to improve the submission of "transaction error reports." EMTS users are now able to enter transaction errors at any time up to six months after the end of the compliance year. See EPA's "Resubmitting or Correcting Reports" webpage for more information.
November 2025
EPA has added a third option through the US Treasury for obligated parties to purchase cellulosic waiver credits (CWC). Obligated parties can directly purchase CWCs using the US Treasury’s Pay.gov app which supports purchases using credit card and bank account (ACH). Additional information on all three options at EPA’s Cellulosic Waiver Credit webpage.
July 2025
EPA has streamlined the procedure for purchasing cellulosic waiver credits. Previously, obligated parties had to record credit purchases through the “OTAQ Biofuel Waiver” credit application within EPA’s Central Data Exchange. This OTAQ Biofuel Waiver application is now offline. Obligated parties can simply choose from any one of three options offered through the US Treasury for purchasing CWCs. Obligated parties should continue to report the total number of CWC credits purchased on the annual RVO report form, also known as the “RFS0304” report form.
April 2025
Unified Reporting Form 3.0 is now available. The URF v3 contains the Renewable Fuel Standard and Gasoline, Diesel and Regulated Blendstock (part 1090 or “STR” series) report forms. The URF v3 provides direct feedback to users on common reporting problems. QA check codes specific to the STR or RFS series report forms are displayed to indicate potential reporting errors, missing information, and other data quality alerts. Report submitters can reference the QA check descriptions to identify and correct potential issues before report submission.
