§ 463.14 New source performance standards.
Current through Aug 22, 2025 · Read all of Part 463
(a) NSPS for bis(2-ethylhexyl) phthalate are reserved.
(b) Any new source subject to this subpart must achieve performance standards (i.e., mass of pollutant discharged), which are calculated by multiplying the average process water usage flow rate for the contact cooling and heating water processes at a new source times the following pollutant concentrations:
Subpart A
[Contact cooling and heating water]
| Concentration used to calculate NSPS | |
|---|---|
| Pollutant or pollutant property | Maximum for any 1 day (mg/l) |
| BOD5 | 26 |
| Oil and grease | 29 |
| TSS | 19 |
| pH | ( 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 contact cooling and heating water processes from the permittee.
