40 C.F.R. § 463.24
Current through September 30, 2024
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) |
1 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.
