Instructions for Electronically Submitting Reports and Fuel Additive Manufacturer Registrations under 40 CFR Part 79

If you are already registered with the Central Data Exchange (CDX), then you may submit your Part 79 fuel additive registration, registration updates, or fuel and fuel additive report forms through the DC Fuels application in CDX, EPA's secure portal for parties to submit data to the Agency. Please see: User Guides for OTAQDCFUELin OTAQREG. After submission, please send an email to FuelsProgramSupport@epa.gov stating that a submission has been uploaded to DC Fuels and include the name of the file and the CDX Transaction ID. Fuel manufacturers/importers should electronically submit fuel requests through OTAQREG using the instructions on Register or Update a Fuel Request under 40 CFR Part 79 page.

If you are not registered with CDX and wish to claim Confidential Business Information (CBI) for any information contained in your submission, then you may establish an account in CDX. You may register as a company (with no facilities) and choose RIN Owner Only as your only business activity. You may then submit materials to EPA via CDX. We encourage you to visit the registration page at How to Register a New Company, Facility or User for Part 80 Fuels Program and to follow the instructions there, and to contact the help desk if assistance is needed.

We do not encourage the submission of materials via email. However, if you are not already registered with CDX and if you do not wish to claim CBI as to any part of your submission, then you may submit your materials via email to FuelsProgramSupport@epa.gov.

We encourage all parties to monitor the EPA website and sign up for ENVIROFLASH alerts. When subscribing, you may indicate interest in Part 79 and/or any other program you wish to follow.
