I don't know how I sent you the unsigned submittal form because I signed it and filed it away.
I'm sorry for that mistake. I didn't have an approval from you regarding the increase in
ammonia for BFI to 254.30 daily max/ 194.96 monthly average so I resent it to you. The
permit was amended in March 2018.

I quickly looked at the IUP amendment for the proposed ammonia daily max limit to 254.30 lbs/day.
It appears that current IUP already has ammonia daily max limit of 254.30 lbs/day. Please verify.
