(c) The following allocations constitute the quantity and quality of pollutants or pollutant properties controlled by this paragraph and attributable to ballast, which may be discharged after the application of best practicable control technology currently available, by a point source subject to this subpart, in addition to the discharge allowed by paragraph (b) of this section. The allocation allowed for ballast water flow, as kg/cu m (lb/M gal), shall be based on those ballast waters treated at the refinery. ------------------------------------------------------------------------ BPT effluent limitations for ballast water ------------------------ Average of Pollutant or pollutant property daily Maximum values for for any 1 30 day consecutive days shall not exceed ------------------------------------------------------------------------ Metric units (kilograms per cubic meter of flow) ------------------------ BOD5........................................... 0.048 0.026 TSS............................................ 0.033 0.021 COD \1\........................................ 0.47 0.24 Oil and grease................................. 0.015 0.008 pH.............................................

(d) 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. (e) 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 practicable control technology currently available 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 15 mg/l oil and grease and 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 15 mg/l oil and grease or 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: ------------------------------------------------------------------------ BPT effluent limitations for contaminated runoff --------------------------- Average of Pollutant or pollutant property daily values Maximum for for 30 any 1 day consecutive days shall not exceed ------------------------------------------------------------------------ Metric units (kilograms per 1,000 m\3\ of flow) --------------------------- BOD5........................................ 48. 26.

(\2\) (\2\) ------------------------------------------------------------------------ \1\ In any case in which the applicant can demonstrate that the chloride ion concentration in the effluent exceeds 1,000 mg/l (1,000 ppm), the permitting authority may substitute TOC as a parameter in lieu of COD. A TOC effluent limitation shall be based on effluent data from the particular refinery which correlates TOC to BOD5. If in the judgment of the permitting authority, adequate correlation data are not available, the effluent limitations for TOC shall be established at a ratio of 2.2 to 1 to the applicable effluent limitations for BOD5. \2\ Within the range of 6.0 to 9.0.
