Wisconsin Administrative Code › Department of Natural Resources › NR 200-299 - Environmental Protection Wisconsin Pollutant Discharge Elimination System › Chapter NR 255 - Battery manufacturing › Subchapter I - General Provisions › Section NR 255.02 - General definitions

Current through June 24, 2024
In addition to the definitions set forth in ch. NR 205 and
					 s.
					 NR
					 211.03, the following definitions apply to this
					 chapter:
(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.
(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.
(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.
(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.
(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.
(6) "Leclanche type batteries" means zinc
				  anode batteries with acid electrolyte.
(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.
(8) "NSPS" means new source performance
				  standards.
(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.
(10) "PSES" means pretreatment standards for
				  existing sources.
(11) "PSNS" means
				  pretreatment standards for new sources.
(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.
(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.
