This is an unusual situation. Normally congress makes laws and the FAA makes aviation regulations (two different things).
In this case congress not (trusting the FAA, likely for good reason) passed a law that directed the FAA to make a new regulation. The law specified certain things (ATP required for 121) but left certain other details up to the FAA (ie rest rule details, reduced standards for ATP for those who attend certain schools).
The FAA could still make adjustments based on feedback during the NPRM process, and in theory congress could also make adjustments via legislation if they feel the FAA did not implement their original intent.
