The determination of the characteristics of a wastewater stream for purposes of this section shall be made as follows: NR 419.045(8)(a)(a) The characteristics shall be determined at a location between the point where the process wastewater exits a process unit and before the process wastewater is exposed to the atmosphere, treated for VOC removal, or mixed with another wastewater stream. For wastewater streams at a facility meeting the applicability requirements under sub. (1) (a) 1. and 2. and which, prior to February 1, 2012, were either actually being mixed, or construction had commenced which would result in the wastewater streams being mixed, the mixing does not establish a limit on where the characteristics may be determined. NR 419.045(8)(b)(b) The flow rate of a wastewater stream shall be determined on the basis of an annual average by one of the following methods: NR 419.045(8)(b)1.1. The highest annual quantity of wastewater managed, based on historical records for the most recent 5 years of operation, or for the entire time the wastewater stream has existed if less than five years, but at least one year. NR 419.045(8)(b)3.3. The maximum design capacity to generate wastewater of the process unit generating the wastewater stream. NR 419.045(8)(b)4.4. Measurements that are representative of the actual, normal wastewater generation rates. NR 419.045(8)(c)(c) The VOC concentration of a wastewater stream shall be determined on the basis of a flow-weighted annual average by one of the methods in this paragraph, or by a combination of the methods. If the department determines, with written concurrence from EPA, that the VOC concentration cannot be adequately determined by the method in subd.1. or 2., the VOC concentration shall be determined in accordance with subd. 3., or by a combination of the methods in subds. 1., 2., and 3. VOC with a Henry’s Law Constant less than 1.8 x 10-6 atm-m3/mole (0.1 y/x) at 25°C may not be included in the determination of VOC concentration. NR 419.045 NoteNote: Examples of sufficient information include material balances, records of chemical purchases, or previous test results.

Collect a minimum of three representative samples from the wastewater stream and determine the affected VOC concentration for each sample in accordance with sub. (5). The affected VOC concentration of the wastewater stream shall be the flow-weighted average of the individual samples. NR 419.045(8)(d)(d) The annual affected VOC loading in wastewater for a wastewater stream shall be the annual average flow rate determined in par. (b) multiplied by the annual average affected VOC concentration determined in par. (c). NR 419.045(8)(e)(e) The annual VOC loading in wastewater for a facility shall be the sum of the annual VOC loading in wastewater for each affected VOC wastewater stream.

This section applies to all facilities and procedures used to remediate or dispose of soil or water contaminated with organic compounds which are direct air contaminant sources and to their owners and operators. NR 419.07 NoteNote: Certain contaminated soils and water are hazardous wastes. Due to the “mixture”, “derived from”, and “contained in” rules found in ch. NR 661, soils and water contaminated by listed hazardous waste under ss. NR 661.31 (1) and 661.32, are also hazardous wastes. In addition, any residue or contaminated soil, water or other debris resulting from the cleanup of a spill of any material listed in s. NR 661.33 is a listed hazardous waste. Soils, water or other debris may also be considered hazardous waste when they exhibit a hazardous characteristic under one of the test procedures of ss. NR 661.20 to 661.24, including the toxicity characteristic leaching procedure test. Contaminated soils and water must be evaluated for the applicability of hazardous waste management rules (chs. NR 660 to 679). The requirements in chs. NR 660 to 679 for the treatment, storage or disposal of hazardous waste must be followed if the contaminated soil or water is hazardous waste. Requirements in chs. NR 700 to 750 may also apply. NR 419.07(2)(2) General requirements. Except as provided in sub. (3), no person may use any procedure to remediate or dispose of soil or water contaminated with organic compounds unless the remediation project meets all of the following conditions: NR 419.07(2)(b)(b) The project will not cause emissions in such quantity, concentration, or duration as to be injurious to human health. NR 419.07(2)(c)(c) The project will not cause emissions in quantities which will substantially contribute to the exceedance of an ambient air quality standard or ambient air increment or cause air pollution. NR 419.07(3)(3) Exemptions. Any procedure or activity listed in this subsection is exempt from the emission limits specified in sub. (4), except those contained in ch. NR 445: NR 419.07(3)(a)(a) Installation and use of devices which remove organic compounds from a private or municipal potable water supply. NR 419.07(3)(b)(b) Installation and use of crop irrigation systems or dewatering wells to remediate contaminated water. NR 419.07(3)(c)(c) Agricultural landspreading of soil contaminated with pesticide or fertilizer. NR 419.07(3)(d)(d) Pilot testing of a negative pressure venting system provided the testing is limited to a total withdrawal of not more than 150,000 standard cubic feet (scf) of air. NR 419.07 NoteNote: The total withdrawal may be determined by the equation: Total withdrawal (scf) = hours of operation of pilot test (hr) × average flow rate in cubic feet per minute at standard conditions (scfm) × 60 min/hr. An example is: 10 hours of operation × 250 scfm × 60 min/hr = 150,000 scf. When testing at multiple flow rates, determine the withdrawal for each flow rate and sum the withdrawals for a total withdrawal.
NR 419.07(3)(e)(e) Discharge to a wastewater treatment plant that is operated in accordance with ch. 283, Stats. NR 419.07 NoteNote: Wastewater treatment plants are not exempt from air permit requirements.
NR 419.07(4)(a)(a) An owner or operator of a soil or water remediation project shall treat or dispose of soil or water contaminated with organic compounds in a manner which minimizes the emission of volatile organic compounds and hazardous air contaminants, including emissions during the handling, transportation and storage of the contaminated soil or water. NR 419.07(4)(b)(b) The emissions from the remediation or disposal of contaminated soil or water may not exceed: NR 419.07(4)(b)1.1. 137 pounds of volatile organic compounds per day in Kenosha, Kewaunee, Manitowoc, Milwaukee, Ozaukee, Racine, Sheboygan, Walworth, Washington or Waukesha county, except as specified in pars.

NR 419.07(4)(e)(e) When remediating contaminated soil at a landspreading facility, the total volatile organic compound contaminants in the soil treated at a source may not exceed 6,000 pounds per year. NR 419.07(4)(f)(f) Except as provided for in sub. (6), the volatile organic compound emissions for pars. (b) and (c) and the volatile organic compound quantity for pars. (d) and (e) are determined by averaging the contaminant concentrations in all samples of the contaminated soil or water analyzed and multiplying that average by the total amount of soil or water to be remediated. If in any sample there is no contamination detected, the detection level of the test method is used for the contaminant concentration in that sample. NR 419.07(4)(g)(g) The volatile organic compound emissions determined for pars. (b) and (c), and the organic compound quantities determined for pars. (d) and (e), may be reduced by any method approved by the bureau of air management. NR 419.07 NoteNote: Methods may include but are not limited to approved destruction efficiency, afterburners, carbon absorption units, etc.
