Any new source subject to this subpart must achieve the following new source performance standards (NSPS):
NSPS Effluent Limitations
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 § 435.41(ff).
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 § 435.41(ee).
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.
