§ 435.44 Effluent limitations guidelines representing the degree of effluent reduction attainable by the application of the best conventional pollutant control technology (BCT).

Except as provided in 40 CFR 125.30- 125.3230-125.32, any existing point source subject to this subpart must achieve the following effluent limitations representing the degree of effluent reduction attainable by the application of the best conventional pollutant control technology (BCT):

BCT Effluent Limitations

Stream Pollutant parameter BCT effluent limitations
Produced Water (all facilities) Oil & Grease The maximum for any one day shall not exceed 72 mg/l and the 30-day average shall not exceed 48 mg/l.
Drilling Fluids and Drill Cuttings and Dewatering Effluent: 1
All facilities except Cook Inlet No discharge.
Cook Inlet:
Water-based drilling fluids, drill cuttings, and dewatering effluent Free Oil No discharge. 2
Non-aqueous drilling fluids and dewatering effluent No discharge.
Drill cuttings associated with non-aqueous drilling fluids Free Oil No discharge. 2
Well Treatment, Workover and Completion Fluids Free Oil No discharge. 2
Produced Sand No discharge.
Deck Drainage Free Oil No discharge. 3
Sanitary Waste:
Sanitary M10 Residual Chlorine Minimum of 1 mg/l maintained as close to this concentration as possible.
Sanitary M91M Floating Solids No discharge.
Domestic Waste Floating Solids and garbage No discharge of Floating Solids or garbage.

1 BCT limitations for dewatering effluent are applicable prospectively. BCT 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).
