Can a producer aggregate multiple shipments into a single batch up to a threshold quantity as long as the batch is within one calendar month?
Yes. In the context of generating RINs and specifying the BBBBB code, producers and importers have the option to define a batch as being comprised of several discreet shipments within a calendar month, so long as the total number of gallon-RINs assigned a unique batch number is less than 100 million. See regulation Sections 80.1125(e) and 80.1126(c).
