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. For instructions on how to submit fuel additive registration requests, please see the information below on this webpage.
