Frequent Questions

Is Puerto Rico considered a domestic producer? There are no federal RVP standards there--do they use summer fuels in the winter complex model?

Puerto Rico refineries are considered federal gasoline producers. If their fuel remains seasonally the same throughout the year, they meet the criteria of a refiner marketing in an area with no seasonal changes, and they are only required to provide three months of data. In such a case, all fuels would be evaluated by the seasonal Complex Model which matches their year-round season. If the fuel does change seasonally, then they are required to provide data on both the "summer" fuel and "winter" fuel.(7/1/94)
