Rippa
Have tests been carried out to determine the contamination level of the new surface? I can't find anything about that in publicly available material, and Infraero haven't said anything about that in recent days, letting the 3mm figure continue to be reported.
The 3mm standing water limit applied to the old surface, not the new one. A new surface would have different characteristics to the old one, and it follows that the old limits would no longer apply.
