The Committee will consider all comments received after the comment period closes.
Um, okay, that's about as clear as mud. I think they mean that they will wait until the comment period closes before they look at the comments, or that they will accept comments as long as the comment period is open. But, you know, they could mean that will only look at the comments that they receive after the comment period closes. Any comments received while the comment period was open will simply be ignored. Could save them a lot of work.
