NR 419.045(2)(f)6.a.a. The affected VOC wastewater stream or affected residual is discharged to a hazardous waste incinerator for which the owner or operator has been issued a final permit under 40 CFR part 270 and complies with the requirements of 40 CFR part 264, subpart O, or has certified compliance with the interim status requirements of 40 CFR part 265, subpart O.
NR 419.045(2)(f)6.b.b. The affected VOC wastewater stream or affected residual is discharged to a process heater or boiler burning hazardous waste for which the owner or operator has either been issued a final permit under 40 CFR part 270 and complies with the requirements of 40 CFR part 266, subpart H, or has certified compliance with the interim status requirements of 40 CFR part 266, subpart H.
NR 419.045(2)(f)6.c.c. The affected VOC wastewater stream or affected residual is discharged to an underground injection well for which the owner or operator has been issued a final permit under 40 CFR part 270 or 40 CFR part 144 and complies with the requirements of 40 CFR part 122. The owner or operator shall comply with all applicable requirements of this subsection prior to the point where the wastewater enters the underground portion of the injection well.
NR 419.045(2)(f)7.7. For each affected residual, the owner or operator shall control for air emissions by complying with pars. (a) to (e) and one of the following requirements:
NR 419.045(2)(f)7.a.a. Recycle the affected residual to a production process on-site or transfer the affected residual off-site for the purpose of recycling. Once an affected residual is returned to a production process, the affected residual is no longer subject to this subsection.
NR 419.045(2)(f)7.b.b. Return the affected residual to the treatment process.
NR 419.045(2)(f)7.c.c. Treat the affected residual to destroy the total combined mass flow rate of affected VOC by 99% or more in a nonbiological treatment process.

NR 419.045(3)(3)Alternative methods of control. The following alternate methods of demonstrating and documenting continuous compliance with the applicable control requirements or exemption criteria in this section may be utilized if approved by the department with written concurrence from EPA:
NR 419.045(3)(a)(a) As an alternative to the control requirements of sub. (2), the owner or operator of waste management units may elect to ensure that the overall control of VOC emissions at the facility from wastewater from affected industrial categories is at least 90% less than the 2011 calendar year baseline emissions for VOC emissions to the ambient air from process wastewater, provided that adequate documentation is submitted to the department which supports the accuracy of the calendar year baseline emissions and the following requirements are met:
NR 419.045(3)(a)1.1. The owner or operator of a waste management unit shall submit a control plan to the department which demonstrates that the overall control of VOC emissions at the facility from wastewater from affected industrial categories will be at least 90% less than the calendar year baseline emissions.

At a minimum, the control plan shall include the applicable emissions units’ identification; the facility identification number; the calendar year baseline emission rates of VOC from wastewater from affected industrial categories consistent with the calendar year baseline emissions; a plot plan showing the location, the emissions units’ identification, and facility identification number associated with a waste management unit; the VOC emission rates for each emissions unit for the preceding calendar year; and an explanation of the recordkeeping procedure and calculations which will be used to demonstrate compliance. The VOC emission rates shall be calculated in a manner consistent with the calendar year baseline emissions.
NR 419.045(3)(a)2.2. The owner or operator shall submit an annual report no later than March 31 of each calendar year to the department which demonstrates that the overall control of VOC emissions from wastewater from affected industrial categories during the preceding calendar year is at least 90% less than the baseline emissions. At a minimum, the report shall include the facility identification number; the emissions units’ identification; the throughput of wastewater from affected industrial categories; a plot plan showing the location; the emissions units’ identification; and the facility identification number associated with waste management units; and the VOC emission rates for the preceding calendar year. The emission rates for the preceding calendar year shall be calculated in a manner consistent with the calendar year baseline emissions.
