NR 233.10(3) (3) This subchapter does not apply to the intermediates used to manufacture the active ingredients, and active ingredients used solely in experimental pesticides. BPT coverage in this subchapter does not apply to insecticidal pathogenic organisms such as bacillus thuringiensis, insect growth hormones, plant extracts such as pyrethrins, sex attractants and botanicals such as Rotenone.
NR 233.10(4) (4) A plant that manufactures a pesticide active ingredient listed in Table 1 shall comply with the BAT effluent limitations, new source performance standards, and pretreatment standards both for that ingredient listed in Table 2 or Table 3, and for priority pollutants listed in Tables 4, 5 and 6. The limitations apply as follows:
NR 233.10(4)(a) (a) Table 4 - BAT and NSPS - applies to existing and new direct discharge point sources that use end-of-pipe biological treatment.
NR 233.10(4)(b) (b) Table 5 - BAT and NSPS - applies to existing and new direct discharge point sources that do not use end-of-pipe biological treatment.
NR 233.10(4)(c) (c) Table 6 - PSES and PSNS - applies to existing and new sources that discharge to POTWs.
NR 233.10(5) (5) 
NR 233.10(5)(a)(a) The discharge quantity for lead and total cyanide shall be determined by multiplying the concentrations listed in the applicable tables times the flow from the non-complexed lead-bearing waste streams for lead and times the flow from non-complexed cyanide-bearing waste streams for total cyanide.
NR 233.10(5)(b) (b) This subchapter does not apply to discharges of cyanide in cyanide-bearing waste streams if:
NR 233.10(5)(b)1. 1. The department or control authority determines that the cyanide limitations and standards are not achievable due to elevated levels of non-amenable cyanide, that is not oxidized by chlorine treatment, that result from the unavoidable complexing of cyanide at the process source of the cyanide-bearing waste stream and establishes an alternative total cyanide or amenable cyanide limitation that reflects the best available technology economically achievable.
NR 233.10(5)(b)2. 2. The determination under subd. 1. shall be based upon a review of relevant engineering, production, and sampling and analysis information, including measurements of both total and amenable cyanide in the waste stream.
NR 233.10(5)(b)3. 3. An analysis of the extent of complexing in the waste stream, based on the information in subds. 1. and 2., and its impact on cyanide treatability shall be set forth in writing and, for direct dischargers, be contained in the fact sheet required by 40 CFR 124.8.
