| Ammonia (as N) | 18.8 | 8.6 |
| Sulfide | 0.105 | 0.048 |
| Total chromium | 0.24 | 0.14 |
| Hexavalent chromium | 0.020 | 0.0088 |
| pH | (2) | (2) |
| English units (pounds per 1,000 bbl of feedstock) | ||
| BOD5 | 5.8 | 3.1 |
| TSS | 4.0 | 2.5 |
| COD1 | 41.5 | 21 |
| Oil and grease | 1.7 | 0.93 |
| Phenolic compounds | 0.042 | 0.020 |
| Ammonia (as N) | 6.6 | 3.0 |
| Sulfide | 0.037 | 0.017 |
| Total chromium | 0.084 | 0.049 |
| Hexavalent chromium | 0.0072 | 0.0032 |
| pH | (2) | (2) |
(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 1 day and maximum average of daily values for 30 consecutive days.
(1) Size Factor.
| 1,000 bbl of feedstock per stream day | Size factor |
|---|---|
| Less than 24.9 | 0.91 |
| 25.0 to 49.9 | 0.95 |
| 50.0 to 74.9 | 1.04 |
| 75.0 to 99.9 | 1.13 |
| 100.0 to 124.9 | 1.23 |
| 125.0 to 149.9 | 1.35 |
| 150.0 or greater | 1.41 |
(2) Process factor.
| Process configuration | Process factor |
|---|---|
| Less than 2.49 | 0.58 |
| 2.5 to 3.49 | 0.63 |
| 3.5 to 4.49 | 0.74 |
| 4.5 to 5.49 | 0.88 |
| 5.5 to 5.99 | 1.00 |
| 6.0 to 6.49 | 1.09 |
| 6.5 to 6.99 | 1.19 |
| 7.0 to 7.49 | 1.29 |
| 7.5 to 7.99 | 1.41 |
| 8.0 to 8.49 | 1.53 |
| 8.5 to 8.99 | 1.67 |
| 9.0 to 9.49 | 1.82 |
| 9.5 or greater | 1.89 |
(3) See the comprehensive example in subpart D, § 419.42(b)(3).
(c) The provisions of § 419.16(c) apply to discharges of process wastewater pollutants attributable to ballast water by a point source subject to the provisions of this subpart.
(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 limitation for runoff. [Reserved]
