Sorry you didn't get a response, Brooke. I search for CASAA related posts daily, but for some reason the posts in our own forum area weren't coming up!
You may have already found your answer elsewhere on ECF, but to answer you question in case others are curious...
There isn't a live hearing. The FDA will post a "docket" online that explains its proposed regulations and open it for the public to submit comments via an online form. However, CASAA representatives have been and will be testifying at FDA panels, workshops and hearings up until (and after, if needed) the proposed regulations are published to try to get consumer concerns addressed.
