Less than 2.49	0.62
2.5 to 3.49	0.67
3.5 to 4.49	0.8
4.5 to 4.49	0.95
5.5 to 5.99	1.07
6.0 to 6.49	1.17
6.5 to 6.99	1.27

9.5 to 9.99	2.12
10.0 to 10.49	2.31
10.5 to 10.99	2.51
11.0 to 11.49	2.73
11.5 to 11.99	2.98
12.0 to 12.49	3.24
12.5 to 12.99	3.53
13.0 to 13.49	3.84
13.5 to 13.99	4.18
14.0 or greater	4.36

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

(3) The following allocations constitute the quantity and quality of pollutants or pollutant properties controlled by this subsection 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 subcategory, in addition to the discharge allowed by sub. (2). 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.

NSPS Effluent Limitations for Ballast Water
Pollutant or pollutant property	Maximum for any 1 day	Average of daily values for 30 consecutive days
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	0.08
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)

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

² Within the range of 6.0 to 9.0.

(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.
