NR 665.1090 (6) (a).
NR 665.1084(1)(d)
(d) If the owner or operator uses knowledge to determine average VO concentration of a hazardous waste at the point of waste origination, the owner or operator shall do the following:
NR 665.1084(1)(d)1.
1. Prepare documentation that presents the information used as the basis for the owner's or operator's knowledge of the hazardous waste stream's average VO concentration. Examples of information that may be used as the basis for knowledge include material balances for the source or process generating the hazardous waste stream, constituent-specific chemical test data for the hazardous waste stream from previous testing that are still applicable to the current waste stream, previous test data for other locations managing the same type of waste stream or other knowledge based on information included in manifests, shipping papers or waste certification notices.
NR 665.1084(1)(d)2.
2. If test data are used as the basis for knowledge, document the test method, sampling protocol and the means by which sampling variability and analytical variability are accounted for in the determination of the average VO concentration. For example, an owner or operator may use organic concentration test data for the hazardous waste stream that are validated according to Method 301 in appendix A of
40 CFR part 63, incorporated by reference in s.
NR 660.11, as the basis for knowledge of the waste.
NR 665.1084(1)(d)3.
3. If chemical constituent-specific concentration test data are used as the basis for knowledge, the test data may be adjusted to the corresponding average VO concentration value which would have been obtained had the waste samples been analyzed using Method 25D in appendix A of
40 CFR part 60, incorporated by reference in s.
NR 660.11. To adjust these data, multiply the measured concentration for each individual chemical constituent contained in the waste by the appropriate constituent-specific adjustment factor (f
m25D).
NR 665.1084(1)(d)4.
4. In the event that the department and the owner or operator disagree on a determination of the average VO concentration for a hazardous waste stream using knowledge, the department may use the results from a determination of average VO concentration using direct measurement as specified in par.
(c) to establish compliance with the applicable requirements of this subchapter. The department may perform or request that the owner or operator perform this determination using direct measurement. The owner or operator may choose one or more appropriate methods to analyze each collected sample according to par.
(c) 3. NR 665.1084(2)(a)
(a) An owner or operator shall perform the applicable waste determination for each treated hazardous waste placed in a waste management unit exempted under s.
NR 665.1083 (3) (b) 1. to
6. from using air emission controls according to standards in ss.
NR 665.1085 to
665.1088, as applicable to the waste management unit. Make the determinations according to all of the following:
NR 665.1084(2)(a)1.
1. Make an initial determination of the average VO concentration of the waste stream before the first time any portion of the material in the treated waste stream is placed in a waste management unit exempted under s.
NR 665.1083 (3) (b),
(c) or
(d) from using air emission controls, and thereafter update the information used for the waste determination at least once every 12 months following the date of the initial waste determination.
NR 665.1084(2)(a)2.
2. Perform a new waste determination whenever changes to the process generating or treating the waste stream are reasonably likely to cause the average VO concentration of the hazardous waste to increase to a level such that the applicable treatment conditions specified in s.
NR 665.1083 (3) (b),
(c) or
(d) are not achieved.
NR 665.1084(2)(b)
(b) The owner or operator shall designate and record the specific provision in s.
NR 665.1083 (3) (b) under which the owner or operator is performing the waste determination. Perform the waste determination for the treated hazardous waste using the applicable procedures in pars.
(c) to

NR 665.1084(2)(c)
(c) Procedure to determine the average VO concentration of a hazardous waste at the point of waste treatment:
NR 665.1084(2)(c)1.
1. `Identification.' Identify and record the point of waste treatment for the hazardous waste.
NR 665.1084(2)(c)2.
2. `Sampling.' Collect samples of the hazardous waste stream at the point of waste treatment in a manner that minimizes volatilization of organics contained in the waste and in the subsequent sample and collects and maintains an adequately representative sample for analysis by the selected method.
NR 665.1084(2)(c)2.a.
a. Designate and record the averaging period to be used for determining the average VO concentration for the hazardous waste stream on a mass-weighted average basis. The averaging period can represent any time interval that the owner or operator determines is appropriate for the hazardous waste stream but may not exceed 1 year.
NR 665.1084(2)(c)2.b.
b. Collect and analyze a sufficient number of samples, but no less than 4, for a hazardous waste determination. Collect all of the samples for a given waste determination within a one-hour period. The average of the 4 or more sample results constitutes a waste determination for the waste stream. One or more waste determinations may be required to represent the complete range of waste compositions and quantities that occur during the entire averaging period due to normal variations in the operating conditions for the process generating or treating the hazardous waste stream. Examples of the normal variations are seasonal variations in waste quantity or fluctuations in ambient temperature.
NR 665.1084(2)(c)2.c.
c. Collect and handle all samples according to written procedures prepared by the owner or operator and documented in a site sampling plan. The plan shall describe the procedure for collecting representative samples of the hazardous waste stream which minimizes loss of organics throughout the sample collection and handling process and maintains sample integrity. Maintain a copy of the written sampling plan on-site in the facility operating records. An example of acceptable sample collection and handling procedures for a total volatile organic constituent concentration may be found in Method 25D in Appendix A of
40 CFR part 60,
both incorporated by reference in s.
NR 660.11.
NR 665.1084(2)(c)2.d.
d. Prepare and record sufficient information, as specified in the site sampling plan required under subd.
2. c., to document the waste quantity represented by the samples and, as applicable, the operating conditions for the process treating the hazardous waste represented by the samples.
NR 665.1084(2)(c)3.
3. `Analysis.' Prepare and analyze each collected sample according to Method 25D in Appendix A of
40 CFR part 60 for the total concentration of volatile organic constituents, or using one or more methods when the individual organic compound concentrations are identified and summed and the summed waste concentration accounts for and reflects all organic compounds in the waste with Henry's law constant values of at least 0.1 mole-fraction-in-the-gas-phase/mole-fraction-in-the-liquid-phase (0.1 Y/X) [which can also be expressed as 1.8 x 10-6 atmospheres/gram-mole/m3] at 25
°C. At the owner or operator's discretion, the owner or operator may adjust test data obtained by any appropriate method to discount any contribution to the total volatile organic concentration that is a result of including a Henry's law constant value of less than 0.1 Y/X at 25
°C. To adjust these data, the measured concentration of each individual chemical constituent contained in the waste is multiplied by the appropriate constituent-specific adjustment factor (fm25D). If the owner or operator elects to adjust test data, the adjustment shall be made to all individual chemical constituents with a Henry's law constant value greater than or equal to 0.1 Y/X at 25
°C contained in the waste. Constituent specific adjustment factors (fm25D) can be obtained by contacting the Waste and Chemical Processes Group, Office of Air Quality Planning and Standards, Research Triangle Park, NC 27711. Other test methods may be used if they meet the requirements in subd.
3. a. or
b. and provided the requirement to reflect all organic compounds in the waste with Henry's law constant values greater than or equal to 0.1 Y/X [which can also be expressed as 1.8 x 10-6 atmospheres/gram-mole/m3] at 25
°C, is met.
NR 665.1084(2)(c)3.a.
a. Any EPA standard method that has been validated according to “Alternative Validation Procedure for EPA Waste and Wastewater Methods,” Appendix D of
40 CFR part 63.
NR 665.1084(2)(c)3.b.
b. Any other analysis method that has been validated according to the procedures specified in Section 5.1 or Section 5.3, and the corresponding calculations in Section 6.1 or Section 6.3, of Method 301 in Appendix A of
40 CFR part 63. The data are acceptable if they meet the criteria specified in Section 6.1.5 or Section 6.3.3 of Method 301. If correction is required under section 6.3.3 of Method 301, the data are acceptable if the correction factor is within the range 0.7 to 1.30. Other sections of Method 301 are not required.
