A refiner may include oxygenates added to conventional gasoline by a party downstream of the refinery, including a "non-proprietary terminal," provided the refiner has a program in place to ensure that the oxygenate is added as reported by the refiner as required by § 80.101(d)(4)(ii). This program should include such controls as an appropriate contract with the downstream blender, periodic sampling and testing, and audits and inspections as necessary to ensure that the requirements are being met. These are discussed more fully in the preamble to the final rule.(7/1/94)
