If you can point me to a clause that says that proponents have to respond with additional information within certain times, or they have to submit enough information initially that the panel wouldn't have to come back to them for additional scientific studies and information that they're missing—which is what often happens—or their economic conditions aren't right so they requested delay, then I would be happy to see those clauses.
