| 13.0 to 13.49 | 3.84 |
| 13.5 to 13.99 | 4.18 |
| 14.0 or greater | 4.36 |
(3) See the comprehensive example in subpart D, §419.42(b)(3).
(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/Mgal), shall be based on those ballast waters treated at the refinery.
| Pollutant or pollutant property | NSPS Effluent Limitations for Ballast Water | |
|---|---|---|
| Maximum for any 1 day | Average of daily values for 30 consecutive days shall not exceed | |
| Metric units (kilograms per cubic meter of flow) | ||
| BOD5 | 0.048 | 0.026 |
| TSS | 0.033 | 0.021 |
| COD1 | 0.47 | 0.24 |
| Oil and grease | 0.015 | 0.008 |
| pH | (2) | (2) |
| English units (pounds per 1,000 gal of flow) | ||
| BOD5 | 0.40 | 0.21 |
| TSS | 0.27 | 0.17 |
| COD1 | 3.9 | 2.0 |
| Oil and grease | 0.126 | 0.067 |
| pH | (2) | (2) |
1See footnote following table in §419.13(d).
2Within the range of 6.0 to 9.0
(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 runoff. [Reserved]
