The regulations require PTD's on each occasion when any person transfers custody or title of RFG, RBOB or conventional gasoline. Whatever documents (hardcopy or electronic) that are currently utilized for business purposes to memorialize the transaction should be annotated with the PTD information. If the transferee already has received a PTD from a transferor, for a particular delivery of gasoline due to a difference in the time between the change of custody and the change of title, EPA would not require the transferor to provide the transferee with another PTD unless there has been a modification or correction in the information provided on the first PTD between the time of the custody change and the title change. If one party is given title to a particular volume of gasoline and another party is given custody, the transferor should provide an appropriate PTD to each transferee.(7/1/94)
