Great. Thank you very much. So Battery C is also tall?

Good morning Dr. Jones,

The NESHAP limits are based on door size, per 40 CFR 63.302(a)(3).  The doors for Batteries subject to the 3.3% limit are not tall doors.  B Battery doors are subject to the 4% limit because they are tall.  Excluding C Battery, B Battery is the only other Battery with tall doors.

Thanks,

Hello Brett  -  We are looking at your September 2022 submission for method 303 results (attached) and had a question. I see that on each page you have the door data columns labelled according to a "NESHAP Limit". We need to know if these % limits (for all batteries except C) are based on door size or a permit limit? We know that the battery C limit of 2% leaking doors is NOT in the NESHAP but is a permit condition. So, to put the question another way, are the doors on batteries with a 3.3% "NESHAP limit "not tall" doors? And, a related question, is Battery B the only battery with (physically) tall doors, hence the 4% NESHAP limit for tall doors?

We would appreciate your help on this matter. Thanks.
