These tests would not address contamination by the terminal. Also, PTDs do not need to specify the precise sulfur content of the fuel, only that the fuel is compliant with the applicable sulfur standard. If minor contamination occurs, but the fuel still meets the applicable standard, it is not considered a violation, nor does EPA require it to be reported on a PTD.

If tests are done upon receipt from the pipeline, how will PTDs reflect sulfur contamination added by the terminal through common piping, manifolds or at the rack?
