The product transfer documents (PTD) requirements are found in § 80.77 of the regulations for reformulated gasoline and RBOB and in § 80.106 for conventional gasoline.
These sections require that on each occasion when any person transfers title or custody of any gasoline (with the exception of gasoline sold or dispensed at a retail outlet or wholesale purchaser-consumer for use in motor vehicles), the transferor must provide to the transferee the specific information pertaining to the fuel required in the product transfer document sections.
The PTD requirements are not intended to require the creation of any new documentation in most situations. Instead, these requirements intend that parties include the PTD information in the documentation currently used to memorialize the transfer of title or custody of gasoline.(7/1/94)
