Hi, I just renewed a SIU permit.  A few of the categorical limits changed due to the recalculation of production based limits and only those have both daily max limit and monthly average limits.  All other local permit limits have only daily max, not monthly average.  The # used in the AT is the daily max limit for most parameters, as that is the only limit, but when there is a monthly average as well, which do you use in the AT instead?  The way the last permit was set up, the AT used the monthly average permit limit when available.  The daily max is much higher than the monthly average so it makes a big difference in the AT so I want to make sure I use the correct #.   Thanks!
