Universal Citation: WI Admin Code § NR 254.013

Current through August 26, 2024

(1) Except as provided in 40 CFR 125.30 to 125.32, any existing source subject to this subchapter shall achieve the effluent limitations in sub. (2), (3), or (4) representing the degree of effluent reduction attainable by the application of BAT.

(2) IRON AND STEEL BYPRODUCT COKEMAKING.

(a) The following BAT effluent limitations apply:

Table 3

BAT Effluent Limitations
Maximum for any 1 day	Average of daily values for 30 consecutive days
Pollutant or pollutant property	kg/kkg (pounds per 1,000 pounds) of product
Ammonia-N	0.0543	0.0160
Cyanide	0.00638	0.00351
Phenols (4AAP)	0.0000638	0.0000319
Benzene	0.0000319
Naphthalene	0.0000319
Benzo(a)pyrene	0.0000319

(b) Increased loadings, not to exceed 16% above the limitations in par. (a), are allowed for plants which have wet desulfurization systems but only to the extent that such systems generate an increased effluent volume.

(c) Increased loadings, not to exceed 39% above the limitations in par. (a), are allowed for plants which include indirect ammonia recovery systems but only to the extent that such systems generate an increased effluent volume.

(d) The following BAT effluent limitations shall be applicable to plants with physical chemical treatment systems:

Table 4

Phenols (4AAP)	0.0000859	0.0000430
Benzene	0.0000215
Naphthalene	0.0000215
Benzo(a)pyrene	0.0000215

(e) Increased loadings, not to exceed 24% above the limitations in par. (d), are allowed for plants with physical chemical pretreatment systems which have wet desulfurization systems but only to the extent that such systems generate an increased effluent volume.

(3) MERCHANT BYPRODUCT COKEMAKING.

(a) The following BAT effluent limitations apply:

Table 5

Merchant Byproduct Cokemaking

BAT Effluent Limitations
Maximum for any 1 day	Average of daily values for 30 consecutive days
Pollutant or pollutant property	kg/kkg (pounds per 1,000 pounds) of product
Ammonia-N	0.0603	0.0177
Cyanide	0.00709	0.00390
Phenols (4AAP)	0.0000709	0.0000355
Benzene	0.0000355
Naphthalene	0.0000355
Benzo(a)pyrene	0.0000355

(b) Increased loadings, not to exceed 15% above the limitations in par. (a), are allowed for plants which have wet desulfurization systems but only to the extent that such systems generate an increased effluent volume.

(c) Increased loadings, not to exceed 35% of the limitations in par. (a), are allowed for plants which include indirect ammonia recovery systems but only to the extent that such systems generate an increased effluent volume.

(d) The following BAT effluent limitations shall be applicable to plants with physical chemical treatment systems:

Table 6

Iron and Steel Byproduct Cokemaking

BAT Effluent Limitations
Maximum for any 1 day	Average of daily values for 30 consecutive days
Pollutant or pollutant property	kg/kkg (pounds per 1,000 pounds) of product

Phenols (4AAP)	0.000100	0.0000501
Benzene	0.0000250
Naphthalene	0.0000250
Benzo(a)pyrene	0.0000250

(e) Increased loadings, not to exceed 21% above the limitations in par. (d), are allowed for plants with physical chemical pretreatment systems which have wet desulfurization systems but only to the extent that such systems generate an increased effluent volume.

(4) BEEHIVE COKEMAKING. Beehive cokemaking operations may not discharge process wastewaters to waters of the state.
