I submitted my first public input for the 70E standard. Curious how the process works from this point. Will I receive a response letting me know the committee's thoughts on my input?

Congratulations and thanks for taking part in this very important process!!

You should be notified so you have the opportunity to provide public comment.

Also, you can view the first draft report (link below) to see the proposals and see the balloting results. If you have not created a profile, you will need to do that first.
