(a) All volume measurements required by these regulations shall be temperature adjusted to 60 degrees Fahrenheit.
(b) The percentage of oxygen by weight contained in a gasoline blend, based upon its percentage oxygenate by volume and density, shall exclude denaturants and water.
(c) The properties of reformulated gasoline consist of per-gallon values separately and individually determined on a batch-by-batch basis using the methodologies specified in§80.46for each of those physical and chemical parameters necessary to determine compliance with the standards to which the gasoline is subject, and per-gallon values for the VOC, NOX, and toxics emissions performance standards to which the gasoline is subject.
(d) Per-gallon oxygen content shall be determined based upon the weight percent oxygen of a representative sample of gasoline, using the method set forth in §80.46(g). The total oxygen content associated with a batch of gasoline (in percent-gallons) is calculated by multiplying the weight percent oxygen content times the volume.
(e) Per-gallon benzene content shall be determined based upon the volume percent benzene of a representative sample of a batch of gasoline by the method set forth in §80.46(e). The total benzene content associated with a batch of gasoline (in percent-gallons) is calculated by multiplying the volume percent benzene content times the volume.
(f) Per-gallon RVP shall be determined based upon the measurement of RVP of a representative sample of a batch of gasoline. The total RVP value associated with a batch of gasoline (in RVP-gallons) is calculated by multiplying the RVP times the volume.
(g)(1) Per gallon values for VOC and NOXemissions reduction shall be calculated using the methodology specified in§80.45that is appropriate for the gasoline.
(2) Per-gallon values for toxic emissions performance reduction shall be established using:
(i) For gasoline subject to the simple model, the methodology under§80.42that is appropriate for the gasoline; and
(ii) For gasoline subject to the complex model, the methodology specified in§80.45that is appropriate for the gasoline.
(3) The total VOC, NOX, and toxic emissions performance reduction values associated with a batch of gasoline (in percent reduction-gallons) is calculated by multiplying the per-gallon percent emissions performance reduction times the volume of the batch.
