The biodiesel would have no sulphur, because it does not come from fossil fuel. If you add that, it will lower the concentration of sulphur in diesel. That's a plus, even though it would be a very small amount. You put 2% in something that already has just 10 parts per million, because we've gone down from 500 parts per million to 10 parts per million effective June 1 of this year--so we're there.
Do you want to say a word about the technical issues around biodiesel, so it's clear in the mind that it's indeed back on sulphur?
