Comment
After reviewing the 2nd Notice,
I found some question about dehumidifier.
Based on current EPA rule (40 CFR), there is no refrigerant which
are GWP below 750 for residential dehumidifier.

If CARB has already recognied that some refrigerant A2L grade (for
example R32) are under process of EPA approval and it will be
completed befor 2023, it is no  problem.

But if there is no EPA process, then for the residential
dehumidifier, the effective date of 2023 shall be subject to 2025
or after EPA approval.
