NR 284.01NR 284.01 Purpose. The purpose of this chapter is to establish effluent limitations, standards of performance, and pretreatment standards for discharges of process wastes from the pulp and paper industry category of point sources and subcategories thereof. NR 284.01 HistoryHistory: Cr. Register, October, 1986, No. 370, eff. 11-1-86. NR 284.02NR 284.02 Applicability. The effluent limitations, standards of performance, pretreatment standards, and other provisions in this chapter are applicable to pollutants or pollutant properties in discharges of process waste resulting from activities in any or a combination of any of the following subcategories of the pulp and paper manufacturing point source category as defined in s. NR 284.03: NR 284.02(1)(1) Integrated production of pulp and paper or paperboard by: NR 284.02(1)(m)(m) Unbleached kraft-neutral sulfite semi-chemical (cross-recovery) subcategory. NR 284.02(2)(2) Nonintegrated production of paper or paperboard by: NR 284.02(3)(3) Production of paper or paperboard from wastepaper by: NR 284.02 HistoryHistory: Cr. Register, October, 1986, No. 370, eff. 11-1-86. NR 284.03NR 284.03 Definitions. The following definitions are applicable to terms used in this chapter.

NR 284.03(1)(1) “Acid sulfite cooking liquor” means sulfite cooking liquor having a pH less than 3.0. NR 284.03(2)(2) “BCT bleached kraft subcategory” includes those mills at which bleached kraft pulp is produced in a full cook process employing a highly alkaline sodium hydroxide and sodium sulfide cooking liquor. NR 284.03 NoteNote: Principal products include paperboard (B), coarse papers (C), tissue papers (T) and market pulp.
NR 284.03(3)(3) “Bisulfite cooking liquor” means sulfite cooking liquor having a pH between 3.0 and 6.0. NR 284.03(4)(4) “Builders’ paper and roofing felt subcategory” includes those mills at which heavy papers used in the construction industry are produced from wastepaper, wood flour and sawdust, wood chips, and rags. Neither bleaching nor chemical pulping processes are employed on-site. NR 284.03 NoteNote: Principal products include saturating, deadening, and flooring papers, and roofing felt.
NR 284.03(5)(5) “Corrugating medium furnish subdivision” includes those mills in the paperboard from wastepaper subcategory where only recycled corrugating medium is used in the production of paperboard. NR 284.03(6)(6) “Cotton fiber furnish subdivision” includes those mills in the nonintegrated-fine papers subcategory which produce a paper product containing equal to or greater than 4% cotton fibers. NR 284.03(7)(7) “Deink subcategory” includes those mills at which brightened or bleached deinked pulp is produced from wastepapers using an alkaline process to remove contaminants such as ink and coating pigments. NR 284.03 NoteNote: Principal products include fine papers such as printing, writing and business papers, tissue papers, newsprint and market pulp.
NR 284.03(8)(8) “Dissolving kraft subcategory” includes those mills at which a highly bleached pulp is produced by a full cook process employing a highly alkaline sodium hydroxide and sodium sulfide cooking liquor. Included in the manufacturing process is a precook operation termed prehydrolysis. NR 284.03 NoteNote: The principal product at these mills is a highly bleached and purified dissolving pulp used principally for manufacture of rayon and other products requiring the virtual absence of lignin and a very high alpha cellulose content.
NR 284.03(9)(9) “Dissolving sulfite pulp subcategory” includes those mills at which a highly bleached pulp is produced in a full cook process employing strong solutions of sulfites of calcium, magnesium, ammonia or sodium. NR 284.03 NoteNote: Principal products include viscose, nitration, cellophane or acetate grade pulps which are used principally for the manufacture of rayon and other products that require the virtual absence of lignin.
NR 284.03(10)(10) “Fine bleached kraft subcategory” includes those mills at which bleached kraft pulp is produced in a full cook process employing a highly alkaline sodium hydroxide and sodium sulfide cooking liquor. NR 284.03 NoteNote: Principal products are fine papers, which includes business, writing and printing papers, and market pulp.
NR 284.03(11)(11) “Full cook” means chemical pulping methods which employ the heating under pressure of wood, water and chemicals in a closed vessel to a temperature sufficient to separate the fibrous portion of the wood by dissolving lignin and other nonfibrous constituents.
