How will the volume of corn ethanol produced above the grandfathering threshold be treated?
See More Frequent Questions about Fuels Registration, Reporting, and Compliance Help . For grandfathered facilities, only the baseline volumes are exempt from the 20 percent GHG reduction requirement Thus, RINs may be generated for baseline volumes of fuel regardless of lifecycle greenhouse gas emissions performance. Volumes of fuel produced above…

How long will the grandfathering provision be effective? Once a grandfathered producer registers and completes their engineering review, will their baseline volume ever need to meet the 20% GHG reduction requirement?
See More Frequent Questions about Fuels Registration, Reporting, and Compliance Help . If a facility meets the requirements for exemption from the 20% GHG reduction requirement pursuant to 40 CFR 80.1403(c ) or (d), then the baseline volume of renewable fuel produced by that facility is exempt from the 20%…

How does a foreign grandfathered renewable fuel production facility processing a mixture of feedstocks with different D codes or no D codes classify its production into D code categories so RINs can be generated when the product is imported into the U.S.?
See More Frequent Questions about Fuels Registration, Reporting, and Compliance Help . If the importer is generating the RINs, the importer must obtain all the required information for registration from the foreign producer of the renewable fuel pursuant to 80.1426(a)(2) and 80.1450. In the case of a foreign producer using…

If a facility is grandfathered, is it also exempt from the requirement that feedstocks must be renewable biomass?
See More Frequent Questions about Fuels Registration, Reporting, and Compliance Help . Even if a facility is exempt from the 20% GHG reduction requirement, in order to generate RINs, the facility is still required to use feedstocks that meet the definition of renewable biomass. The definition of renewable fuel in…
