NR 464.06(5)(c)(c) Treat the pulping process condensates to reduce or destroy the total HAPs by 92% or more by weight.
NR 464.06(5)(d)(d) At mills that do not perform bleaching, treat the pulping process condensates to remove 3.3 kilograms or more of total HAP per megagram (6.6 pounds per ton) of ODP, or achieve a total HAP concentration of 210 parts per million or less by weight at the outlet of the control device.
NR 464.06(5)(e)(e) At mills that perform bleaching, treat the pulping process condensates to remove 5.1 kilograms or more of total HAP per megagram (10.2 pounds per ton) of ODP, or achieve a total HAP concentration of 330 parts per million or less by weight at the outlet of the control device.
NR 464.06(6)(6)Each HAP removed from a pulping process condensate stream during treatment and handling under sub. (4) or (5), except for those treated according to sub. (5) (b), shall be controlled as specified in s. NR 464.03 (3) and (4).
NR 464.06(7)(7)For each control device, such as a steam stripper system or other equipment serving the same function, used to treat pulping process condensates to comply with the requirements specified in sub. (5) (c) to (e), periods of excess emissions reported under s. NR 464.05 are not a violation subs. (4) and (5) (c) to (e) and (6) provided that the time of excess emissions, including periods of startup, shutdown or malfunction, divided by the total process operating time in a semi-annual reporting period does not exceed 10%. The 10% excess emissions allowance does not apply to treatment of pulping process condensates according to sub. (5) (b) as done, for example, with the biological wastewater treatment system used to treat multiple wastewater streams to comply with the clean water act.
NR 464.06(8)(8)Each owner or operator of a new or existing affected source subject to the requirements of this section shall evaluate all new or modified pulping process condensates or changes in the annual bleached or non-bleached ODP used to comply with sub. (9) to determine if they meet the applicable requirements of this section.
NR 464.06(9)(9)For the purposes of meeting the requirements in sub. (3) (b) or (c) or (5) (d) or (e) at mills producing both bleached and unbleached pulp products, owners and operators may meet a prorated mass standard that is calculated by prorating the applicable mass standards (kilograms of total HAP per megagram of ODP) for bleached and unbleached mills specified in sub. (3) (b) or (c) or (5) (d) or (e) by the ratio of annual megagrams of bleached and unbleached ODP.

NR 464.07NR 464.07Clean condensate alternative. As an alternative to the requirements specified in s. NR 464.03 (1) (a) 2. to 5. for the control of HAP emissions from pulping systems using the kraft process, an owner or operator shall demonstrate to the satisfaction of the department, by meeting all the requirements of this section, that the total HAP emissions reductions achieved by this clean condensate alternative technology are equal to or greater than the total HAP emission reductions that would have been achieved by compliance with s. NR 464.03 (1) (a) 2. to 5.
NR 464.07(1)(1)For the purposes of this section only the following additional definitions apply:
NR 464.07(1)(a)(a) “Clean condensate alternative affected source” means the total of all HAP emission points in the pulping, bleaching, causticizing and papermaking systems, exclusive of HAP emissions attributable to additives to paper machines and HAP emission points in the LVHC system.
NR 464.07(1)(b)(b) “Causticizing system” means all equipment associated with converting sodium carbonate into active sodium hydroxide. The equipment includes smelt dissolving tanks, lime mud washers and storage tanks, white and mud liquor clarifiers and storage tanks, slakers, slaker grit washers, lime kilns, green liquor clarifiers and storage tanks, and dreg washers ending with the white liquor storage tanks prior to the digester system, and any other equipment serving the same function as those previously listed.
NR 464.07(1)(c)(c) “Papermaking system” means all equipment used to convert pulp into paper, paperboard or market pulp, including the stock storage and preparation systems, the paper or paperboard machines, and the paper machine white water system, broke recovery systems, and the systems involved in calendering, drying, on-machine coating, slitting, winding and cutting.
NR 464.07(2)(2)Each owner or operator shall install and operate a clean condensate alternative technology with a continuous monitoring system to reduce total HAP emissions by treating and reducing HAP concentrations in the pulping process water used within the clean condensate alternative affected source.
NR 464.07(3)(3)Each owner or operator shall calculate HAP emissions on a kilogram per megagram of ODP basis and measure HAP emissions according to the appropriate procedures contained in 40 CFR 63.457, incorporated by reference in s. NR 484.03 (6).
NR 464.07(4)(4)Each owner or operator shall determine the baseline HAP emissions for each equipment system and the total of all equipment systems in the clean condensate alternative affected source based on the following:
