Section 80.2(gg) defines a "batch of reformulated gasoline" as "a quantity of reformulated gasoline which is homogeneous with regard to those properties which are specified for reformulated gasoline certification." The reported volume for the batch should be the volume of reformulated gasoline shipped out of the refinery or import facility after the gasoline has been blended and sampled.

In the example above, the volume for batch 1 would be 70,000 (50,000 + 20,000) barrels and the volume for batch 2 would be 72,000 (28,000 + 44,000) barrels. For a discussion of the method for determining batch size by independent laboratories, see Independent Sampling/Testing Section, Question 19.(7/1/94)
