Yes, on the proponent's request for an extension. That's all the proponent wants. The proponent isn't offering additional information and isn't proposing to open Pandora's box again, but simply saying, “You've asked for these studies and information. The time limit that you've provided me with by legislation is not quite enough. I need an extension”.
The agency says, “Sure, we'll give you an extension. However, you know that Pandora's box? It's now open, and we need additional information and studies.”
We're simply eliminating that potential penalty for asking for an extension.
