(a) Except as provided in 40 CFR 403.7, any new source subject to this subpart and producing titanium dioxide by the sulfate process which introduces pollutants into a publicly owned treatment works must comply with 40 CFR part 403 and achieve the following pretreatment standards for new sources (PSNS):
Subpart V - Titanium Dioxide - Sulfate Process
| Pollutant or pollutant property | PSNS effluent limitations | |
|---|---|---|
| Maximum for any 1 day | Average of daily values for 30 consecutive days | |
| Milligrams per liter (mg/1) | ||
| Iron (T) | 8.5 | 2.5 |
| Chromium (T) | 0.57 | 0.30 |
| Nickel (T) | 0.38 | 0.20 |
In cases where POTWs find it necessary to impose mass limitations, the following equivalent mass limitations are provided as an alternate: The limitations for Iron(T), Chromium(T), and Nickel(T) are the same as specified in § 415.225(a).
(b) Except as provided in 40 CFR 403.7, any new source subject to this subpart and producing titanium dioxide by the chloride process which introduces pollutants into a publicly owned treatment works must comply with 40 CFR part 403 and achieve the following pretreatment standards for new sources (PSNS):
Subpart V - Titanium Dioxide-Chloride Process
| Pollutant or pollutant property | PSNS effluent limitations | |
|---|---|---|
| Maximum for any 1 day | Average of daily values for 30 consecutive days | |
| Milligrams per liter (mg/1) | ||
| Iron (T) | 5.3 | 1.6 |
| Chromium (T) | 0.23 | 0.12 |
In cases where POTWs find it necessary to impose mass limitations, the following equivalent mass limitations are provided as guidance: The limitations for Iron(T) and Chromium(T) are the same as specified in § 415.255(b).
(c) Except as provided in § 403.7, any new source subject to this subpart and producing titanium dioxide by the simultaneous beneficiation-chlorination (chloride-ilmenite) process which introduces pollutants into a publicly owned treatment works must comply with 40 CFR part 403 and achieve the following pretreatment standards for new sources (PSNS):
Subpart V - Titanium Dioxide-Chloride-Ilmenite Process
| Pollutant or pollutant property | PSNS effluent limitations | |
|---|---|---|
| Maximum for any 1 day | Average of daily values for 30 consecutive days | |
| Milligrams per liter (mg/l) | ||
| Iron (T) | 5.3 | 1.6 |
| Chromium (T) | 0.23 | 0.12 |
| Nickel (T) | 0.33 | 0.17 |
In cases where POTWs find it necessary to impose mass limitations, the following equivalent mass limitations are provided as an alternate: The limitations for Iron (T), Chromium (T), and Nickel (T) are the same as specified in § 415.225(c).
