List of All Fuel and Fuel Additive Reports

Streamlining of Reporting Requirements for Fuel Manufacturers subject to 40 CFR Part 79

Fuel manufacturers and importers no longer need to submit the Report for Motor Vehicle Gasoline or Diesel Fuel (Form 3520-12Q) on a quarterly basis – this report is required on an annual basis, with the first annual report for 2021 due by March 31, 2022.

Per 40 CFR part 79 5(a)(1), fuel manufacturers are required to submit an annual report. However, in the interim, a fuel manufacturer should submit a 3520-12Q indicating the 4th quarter of 2021 but reporting for all of 2021.

In addition, fuel manufacturers must submit an annual report per 40 CFR part 79 5(a)(2) via EPA form 3520-12A.

Per 40 CFR part 79 5(b), fuel additive manufacturers must submit an annual report via EPA form 3520-13A.

These reports should be submitted via DCFuels in accordance with the instruction at: Fuels Programs Mailing Addresses
