When no oxygenates are added to gasoline, must an oxygenate analysis be performed?

Under the anti-dumping requirements, the refiner and importer is required to determine the properties of each batch of gasoline required for determining compliance with the applicable standards.

Under the simple model, an analysis for oxygenates would clearly be unnecessary. If a particular batch of gasoline has been imported or received from another refiner or the refiner is using the complex model, then a full analysis, including oxygenates, is appropriate.

If, however, the refiner has produced conventional gasoline under the complex model from crude oil without the addition of any oxygenates, an analysis for oxygenates would not be necessary. Under the RFG program, a refiner is required to ensure compliance with the applicable oxygen requirements and must test accordingly.(7/1/94)
