§ 419.43 Effluent limitations guidelines representing the degree of effluent reduction attainable by the application of the best available technology economically achievable (BAT).
(a) Except as provided in 40 CFR 125.30 through 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 available technology economically achievable (BAT):
Pollutant or pollutant property BAT effluent limitations Maximum for any 1 day Average of daily values for 30 consecutive days shall not exceed Metric units (kilograms per COD1 360.0 187.0 Ammonia as N 23.4 10.6 Sulfide 0.33 0.150 English units (pounds per 1,000 bbl of feedstock) COD1 127.0 66.0 Ammonia as N 8.3 3.8 Sulfide 0.118 0.053 (b) The limits set forth in paragraph (a) of this section are to be multiplied by the following factors to calculate the maximum for any one day and maximum average of daily values for thirty consecutive days.

(c)
(1) In addition to the provisions contained above pertaining to COD, ammonia and sulfide, 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 available technology economically achievable (BAT):
(i) For each of the regulated pollutant parameters listed below, the effluent limitation for a given refinery is the sum of the products of each effluent limitation factor times the applicable process feedstock rate, calculated as provided in 40 CFR 122.45(b). Applicable production processes are presented in appendix A, by process type. The process identification numbers presented in this appendix A are for the convenience of the reader. They can be cross-referenced in the Development Document for Effluent Limitations Guidelines, New Source Performance Standards, and Pretreatment Standards for the Petroleum Refining Point Source Category (EPA 440/1-82/014), Table III-7, pp. 49-54.
Pollutant or pollutant property and process type BAT effluent limitation factor Maximum for any 1 day Average of daily values for 30 consecutive days shall not exceed Metric units (kilograms per 1,000 m3 of feedstock) Phenolic compounds (4AAP): Crude 0.037 0.009 Cracking and coking 0.419 0.102 Asphalt 0.226 0.055 Lube 1.055 0.257 Reforming and alkylation 0.377 0.092 Total chromium: Crude 0.030 0.011 Cracking and coking 0.340 0.118 Asphalt 0.183 0.064 Lube 0.855 0.297 Reforming and alkylation 0.305 0.106 Hexavalent chromium: Crude 0.0019 0.0009 Cracking and coking 0.0218 0.0098 Asphalt 0.0117 0.0053 Lube 0.0549 0.0248 Reforming and alkylation 0.0196 0.0088 English units (pounds per 1,000 bbl of feedstock) Phenolic compounds (4AAP): Crude 0.013 0.003 Cracking and coking 0.147 0.036 Asphalt 0.079 0.019 Lube 0.369 0.090 Reforming and alkylation 0.132 0.032 Total chromium: Crude 0.011 0.004 Cracking and coking 0.119 0.041 Asphalt 0.064 0.022 Lube 0.299 0.104 Reforming and alkylation 0.107 0.037 Hexavalent chromium: Crude 0.0007 0.0003 Cracking and coking 0.0076 0.0034 Asphalt 0.0041 0.0019 Lube 0.0192 0.0087 Reforming and alkylation 0.0069 0.0031 (2) Example Application of Effluent Limitations Guidelines as Applicable to Phenolic Compounds, Hexavalent Chromium, and Total Chromium.
The following example presents the derivation of a BAT phenolic compound (4AAP) effluent limitation (30-day average) for a petroleum refinery permit. The methodology is also applicable to hexavalent chromium and total chromium.
Refinery process Process feedstock rate 1,000 bbl/day 1. Atmospheric crude distillation 100 2. Crude desalting 50 3. Vacuum crude distillation 75 Total crude processes (C) 225 6.

Catalytic reforming 10 Total reforming and alkylation processes (R) 10 Note:30 day average effluent limitation for phenolic compounds (4AAP), lb/day = (0.003) (225) + (0.036) (45) + (0.019) (5) + (0.090) (3) + (0.032) (10) = 2.98 lb/day.
(d) The provisions of § 419.13(d) apply to discharges of process wastewater pollutants attributable to ballast water by a point source subject to the provisions of this subpart.
(e) The quantity and quality of pollutants or pollutant properties controlled by this paragraph, attributable to once-through cooling water, are excluded from the discharge allowed by paragraph (b) of this section. Once-through cooling water may be discharged with a total organic carbon concentration not to exceed 5 mg/l.
(f) Effluent limitations for contaminated runoff. The following effluent limitations constitute the quantity and quality of pollutants or pollutant properties controlled by this paragraph and attributable to contaminated runoff, which may be discharged after the application of the best available technology economically achievable by a point source subject to this subpart.
(1) If wastewater consists solely of contaminated runoff and is not commingled or treated with process wastewater, it may be discharged if it does not exceed 110 mg/l total organic carbon (TOC) based upon an analysis of any single grab or composite sample.
(2) If contaminated runoff is commingled or treated with process wastewater, or if wastewater consisting solely of contaminated runoff which exceeds 110 mg/l TOC is not commingled or treated with any other type of wastewater, the quantity of pollutants discharged shall not exceed the quantity determined by multiplying the flow of contaminated runoff as determined by the permit writer times the concentrations listed in the following table:
