¹ See footnote following table in s. NR 279.13(4).

² Within the range of 6.0 to 9.0.

(2) The limits set forth in sub. (1) shall be multiplied by the following factors to calculate the maximum for any one day and maximum average of daily values for 30 consecutive days.

(a) Size factor.

1000 bbl. of feedstock per stream day	Size factor
Less than 24.9	0.73
25.0 to 49.9	0.76
50.0 to 74.9	0.83
75.0 to 99.9	0.91
100.0 to 124.9	0.99
125.0 to 149.9	1.08
150.0 or greater	1.13

(b) Process factor.

Process configuration	Process factor
Less than 4.49	0.73
4.5 to 5.49	0.8
5.5 to 5.99	0.91
6.0 to 6.49	0.99
6.5 to 6.99	1.08
7.0 to 7.49	1.17
7.5 to 7.99	1.28
8.0 to 8.49	1.39
8.5 to 8.99	1.51
9.0 to 9.49	1.65
9.5 or greater	1.72

Note: See the comprehensive example in s. NR 279.42(2) (c).

(3) The provisions of s. NR 279.16(3) apply to discharges of process wastewater pollutants attributable to ballast water by a point source subject to the provisions of this subcategory.

(4) The quantity and quality of pollutants or pollutant properties controlled by this subsection, attributable to once-through cooling water, are excluded from the discharge allowed by sub. (2). Once-through cooling water may be discharged with a total organic carbon concentration not to exceed 5 mg/l.
