- § 438.10 - Applicability.
- § 438.12 - Effluent limitations attainable by the application of the best practicable control technology currently available (BPT).
- § 438.13 - Effluent limitations attainable by application of the best control technology for conventional pollutants (BCT).

§ 438.10 - Applicability.
(a) This subpart applies to process wastewater directly discharged from facilities specified at § 438.1.
(b) This subpart applies to process wastewater discharges from oily operations (as defined at § 438.2(f) and appendix B of this part).
(c) This subpart does not apply to process wastewater discharges from metal-bearing operations (as defined at § 438.2(d) and appendix C of this part).
§ 438.12 - Effluent limitations attainable by the application of the best practicable control technology currently available (BPT).
Except as provided at 40 CFR 125.30 through 125.32, any existing point source subject to this subpart must achieve the following effluent limitations representing the application of BPT. Discharges must remain within the pH range 6 to 9 and must not exceed the following:
Effluent Limitations
[BPT]
| Regulated parameter | Maximum daily 1 | 1. TSS | 62 | 2. O&G (as HEM) | 46 |
|---|
1 mg/L (ppm).
§ 438.13 - Effluent limitations attainable by application of the best control technology for conventional pollutants (BCT).
Except as provided at 40 CFR 125.30 through 125.32, any existing point source subject to this subpart must achieve the following effluent limitation representing the application of BCT: Limitations for TSS, O&G (as HEM) and pH are the same as the corresponding limitation specified at § 438.12.
§ 438.15 - New source performance standards (NSPS).
New point sources subject to this subpart must achieve the new source performance standards (NSPS) for TSS, O&G (as HEM), and pH, which are the same as the corresponding limitation specified at § 438.12. The performance standards apply with respect to each new point source that commences discharge after June 12, 2003.
