40 CFR 435.45 - Standards of performance for new sources (NSPS).
§ 435.45
Standards of performance for new sources (NSPS).
Any new source subject to this subpart must achieve the following new source performance standards (NSPS):
| Stream | Pollutant parameter | NSPS effluent limitations |
|---|---|---|
| Produced Water: | ||
| (A) All coastal areas except Cook Inlet | No discharge. | |
| (B) Cook Inlet | Oil & Grease | The maximum for any one day shall not exceed 42 mg/l, and the 30-day average shall not exceed 29 mg/l. |
| Drilling Fluids, Drill Cuttings, and Dewatering Effluent: 1 | ||
| (A) All coastal areas except Cook Inlet | No discharge. | |
| (B) Cook Inlet: | ||
| Water-based drilling fluids, drill cuttings, and dewatering effluent | SPP Toxicity | Minimum 96-hour LC5. of the SPP Toxicity Test 4 shall be 3% by volume. |
| Free oil | No discharge. 2 | |
| Diesel oil | No discharge. | |
| Mercury | 1 mg/kg dry weight maximum in the stock barite. | |
| Cadmium | 3 mg/kg dry weight maximum in the stock barite. | |
| Non-aqueous drilling fluids and dewatering effluent | No discharge. | |
| Drill cuttings associated with non-aqueous drilling fluids | No discharge. 5 | |
| Well Treatment, Workover and Completion Fluids: | ||
| (A) All coastal areas except Cook Inlet | No discharge. | |
| (B) Cook Inlet | Oil & Grease | The maximum for any one day shall not exceed 42 mg/l, and the 30-day average shall not exceed 29 mg/l. |
| Produced Sand | No discharge. | |
| Deck Drainage | Free Oil 3 | No discharge. |
| Sanitary Waste | ||
| Sanitary M10 | Residual Chlorine | Minimum of 1 mg/l and maintained as close to this concentration as possible. |
| Sanitary M9IM | Floating Solids | No discharge. |
| Domestic Waste | Floating Solids, Garbage and Foam | No discharge of floating solids or garbage or foam. |
| 1 NSPS limitations for dewatering effluent are applicable prospectively. NSPS limitations in this rule are not applicable to discharges of dewatering effluent from reserve pits which as of the effective date of this rule no longer receive drilling fluids and drill cuttings. Limitations on such discharges shall be determined by the NPDES permit issuing authority. | ||
| 2 As determined by the static sheen test (see appendix 1 to 40 CFR part 435 , subpart A). | ||
| 3 As determined by the presence of a film or sheen upon or a discoloration of the surface of the receiving water (visual sheen). | ||
| 4 As determined by the suspended particulate phase (SPP) toxicity test (see appendix 2 of subpart A of this part). | ||
| 5 When Cook Inlet operators cannot comply with this no discharge requirement due to technical limitations (see appendix 1 of subpart D of this part), Cook Inlet operators shall meet the same stock limitations (C16-C18 internal olefin) and discharge limitations for drill cuttings associated with non-aqueous drilling fluids for operators in Offshore waters (see § 435.15 ) in order to discharge drill cuttings associated with non-aqueous drilling fluids. | ||
