As far as I know no one has proposed any changes to the regulatory limits for emissions but if they do, there is a science-based process that is required and involves several federal agencies as well as state agency stakeholders, public comment, etc.   One other interesting point, states cannot have rules that are less stringent than the Federal ones but theirs can be more stringent.  In my experience the vast majority of changes to limits are to make them more stringent although there have been some that were overly conservative and have been properly rolled back.
