2. (b) For the purpose of determining the sulfur content, in percent sulfur by weight, for blended liquid fuel, the owner or operator shall use one of the following procedures:

   1. (1) An analysis of the blended product following the applicable methods specified in (a), above; or
   2. (2) An analysis of each blended fuel constituent following the applicable methods specified in (a), above, combined with weight averaging of the constituents.

3. (c) If the procedure in (b)(2), above, is used, the owner or operator shall:

   1. (1) Calibrate all flow meters and instrumentation used in the weight averaging measurement in accordance with the manufacturer’s recommended procedures; and
   2. (2) Document and maintain on file such calibration and date of calibration.
