# 463.24 New source performance standards.Any new source subject to this subpart must achieve performance standards (*i.e.*, mass of pollutant discharged) calculated by multiplying the average process water usage flow rate for cleaning processes at a new source times the following pollutant concentrations:Subpart B[Cleaning water]| Pollutant or pollutant property | Maximum for any 1 day (mg/l) | Maximum for monthly average (mg/l) || --- | --- | --- || BOD | 49 | 22 || Oil and Grease | 71 | 17 || TSS | 117 | 36 || pH | () | () || Within the range of 6.0 to 9.0 at all times. | | |The permit authority will obtain the average process water usage flow rate for the new source cleaning water processes from the permittee.
