A proprietor of an alcohol fuel plant must record entries required by this subpart in the proprietor's records on a daily basis, as the transaction or operation occurs, but not later than the close of the next business day after the occurrence of the transaction or operation. However, if a proprietor prepares supplemental or auxiliary records when an operation or transaction occurs and those records contain all of the information required under this subpart, the proprietor may make entries in the required records not later than the close of business on the third business day following the day on which the transaction or operation occurred.
