If a plant establishes RINs at the beginning of the month and defines it as one month's production estimate (e.g. 8 million gallons), what happens if the plant produces more than 8 million gallons by the end of the month? Does the plant then start issuing a new batch number for the next 8 million gallon RIN? What if this happens in the middle of filling a rail car?
See More Frequent Questions about Fuels Registration, Reporting, and Compliance Help . RINs are not generated at the beginning of a month. Rather, gallon-RINs must have been generated by the time a volume of renewable fuel is transferred from the producer or importer to another party (at which point the…
