NR 255.01
NR 255.01 Purpose. The purpose of this chapter is to establish effluent limitations, standards of performance, and pretreatment standards for discharges of process wastes from the battery manufacturing category of point sources and its subcategories.
NR 255.01 History
History: Cr.
Register, November, 1987, No. 383, eff. 12-1-87.
NR 255.015
NR 255.015 Applicability. This chapter applies to any battery manufacturing plant that discharges or may discharge a pollutant to waters of the state or that introduces pollutants into a publicly owned treatment works. Battery manufacturing operations subject to regulation under this chapter are not subject to regulation under
chs. NR 260 and
261.
NR 255.015 History
History: Cr.
Register, November, 1987, No. 383, eff. 12-1-87.
NR 255.02
NR 255.02 General definitions. In addition to the definitions set forth in
ch. NR 205 and
s. NR 211.03, the following definitions apply to this chapter:
NR 255.02(1)
(1) “Ancillary operations" means all of the operations specific to battery manufacturing and not included specifically within anode or cathode manufacture. Ancillary operations are primarily associated with battery assembly and chemical production of anode or cathode active materials.
NR 255.02(2)
(2) “Battery" means a modular electric power source where part or all of the fuel is contained within the unit and electric power is generated directly from a chemical reaction rather than indirectly through a heat cycle engine. In this chapter, there is no differentiation between a single cell and a battery.
NR 255.02(3)
(3) “Battery manufacturing operations" means all of the specific processes used to produce a battery including the manufacture of anodes and cathodes and associated ancillary operations. These manufacturing operations are excluded from regulation under any other point source category.
NR 255.02(4)
(4) “Discharge allowance" means the amount of pollutant that a plant will be permitted to discharge measured by mg. per kg. of production unit. For purposes of this chapter, the allowances are specific to battery manufacturing operations.
NR 255.02(5)
(5) “Existing source" means any point source, except a new source as defined in
sub. (9), from which pollutants may be discharged either into the waters of the state or into a POTW.
NR 255.02(6)
(6) “Leclanche type batteries" means zinc anode batteries with acid electrolyte.
NR 255.02(7)
(7) “Miscellaneous wastewater streams" means the combined wastewater streams from the process operations within each of 4 subcategories: cadmium, lead, lithium, and zinc. If a plant has one of these wastewater streams, then the plant receives the entire miscellaneous wastewater stream allowance. The process operations for the cadmium subcategory are cell wash, electrolyte preparation, floor and equipment wash, and employe wash. The process operations for the lead subcategory are floor wash, wet air pollution control, battery repair, laboratory, hand wash, and respirator wash. The process operations for the lithium subcategory are floor and equipment wash, cell testing, and lithium scrap disposal. The process operations for the zinc subcategory are cell wash, electrolyte preparation, employe wash, reject cell handling, and floor and equipment wash.
NR 255.02(8)
(8) “NSPS" means new source performance standards.
NR 255.02(9)
(9) “New source," as defined for NSPS and PSNS, means any point source from which pollutants may be discharged directly into the waters of the state or into a POTW, the construction of which commenced after November 10, 1982.
NR 255.02(10)
(10) “PSES" means pretreatment standards for existing sources.
NR 255.02(11)
(11) “PSNS" means pretreatment standards for new sources.
NR 255.02(12)
(12) “Plate soak" means the process operation of soaking or reacting lead subcategory battery plates, that are more than 2.5 mm. or 0.100 in. thick, in sulfuric acid.
NR 255.02(13)
(13) “Trucked batteries" means batteries moved into or out of the plant by truck when the truck is actually washed in the plant to remove residues left in the truck from the batteries.
