Fuels Registration, Reporting, and Compliance Help

Register or Update a Fuel Request under 40 CFR Part 79

New Electronic Process for Fuel Manufacturers subject to 40 CFR Part 79 Submitting Fuel Requests

Starting Wednesday, July 22, 2020, fuel manufacturers/importers that originally submitted hard copies of Form 3520-12 (Fuel Manufacturer Notification for Motor Vehicle Fuel) to register a fuel under 40 CFR Part 79 will only be able to electronically submit this information through the OTAQREG system in EPA's Central Data Exchange (CDX). These manufacturers/importers will NO LONGER be required to mail hard copies of Form 3520-12. Additional required information for registration must be uploaded into the OTAQREG system.

In order to electronically submit Part 79 fuel registration requests through OTAQREG, your company must have a company registered in the OTAQREG system. For instructions on how fuel manufacturers/importers electronically submit fuel requests through OTAQREG, please see the information below on this webpage.

Note: Electronic submission for Part 79 Periodic Reports and Fuel Additive Manufacturers will take effect at a later date. Manufacturers should continue the same submission process for submitting reports, new fuel additive requests and fuel additive update requests. Please see fuel additive information here: Register a Fuel Additive under 40 CFR Part 79.
