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]
Concentration used to calculate NSPS | ||
---|---|---|
Pollutant or pollutant property | Maximum for any 1 day (mg/l) | Maximum for monthly average (mg/l) |
BOD5 | 49 | 22 |
Oil and Grease | 71 | 17 |
TSS | 117 | 36 |
pH | (1) | (1) |
The permit authority will obtain the average process water usage flow rate for the new source cleaning water processes from the permittee.
