The modification are as follows: • IUP 000033: Pipe 02 flow limit went from a daily maximum of 0.044 MGD to a monthly average of 0.044 MGD. • IUP 000040: Pipe 01 flow limit went from a daily maximum of 0.027 MGD to a monthly average of 0.027 MGD. The pipe 02 flow limit went from a daily maxi- mum of 0.0373 MGD to a monthly average of 0.0373. Changing the flow limits to monthly averages as opposed to daily maximums more accu- rately depicts both facilities batch processing practices.
