subch. XII of ch. NR 254 Subchapter XII — Hot Coating Subcategory
NR 254.12 NR 254.12  Applicability; description of the hot coating subcategory.
NR 254.12(1)(1) This subchapter applies to the discharge of pollutants to waters of the state and the introduction of pollutants into POTWs from operations in which steel is coated with zinc, terne metal, or other metals by the hot dip process. The hot coating subcategory includes the associated rinsing operations.
NR 254.12(2) (2) For zinc, the BPT limitations set forth in s. NR 254.122 and the BAT limitations set forth in s. NR 254.123 are not applicable to hot coating operations with wastewater treatment facilities achieving, during normal production, zinc discharge levels more stringent than the BPT and BAT limitations. For such operations, the BPT and BAT limitations for zinc shall be determined on a case-by-case basis based upon the existing performance of the wastewater treatment facility. The permitting authority shall evaluate effluent data from the wastewater treatment facility during periods of normal production to establish the case-by-case BPT and BAT limitations. The BPT and BAT limitations specified in ss. NR 254.122 and 254.123 may be used for calculating the total mass limitations for zinc pursuant to s. NR 254.003.
NR 254.12 History History: Cr. Register, May, 1989, No. 401, eff. 6-1-89.
NR 254.121 NR 254.121  Specialized definitions. The following definitions are applicable to the terms used in this subchapter:

NR 254.121(2) (2) “Galvanizing” means coating steel products with zinc by the hot dip process including the immersion of the steel product in a molten bath of zinc metal, along with the related preceding and subsequent operations.
NR 254.121(3) (3) “Other coatings” means coating steel products with metals other than zinc or terne metal by the hot dip process including the immersion of the steel product in a molten bath of metal, along with the related preceding and subsequent operations.
NR 254.121(4) (4) “Strip, sheet, and miscellaneous products” means steel products other than wire products and fasteners.
NR 254.121(5) (5) “Terne coating” means coating steel products with terne metal by the hot dip process including the immersion of the steel product in a molten bath of lead and tin, along with the related preceding and subsequent operations.
NR 254.121(6) (6) “Wire products and fasteners” means steel wire, products manufactured from steel wire, and steel fasteners manufactured from steel wire or other steel shapes.
