NR 665.1084(1)(a)(a) An owner or operator shall determine the average VO concentration at the point of waste origination for each hazardous waste placed in a waste management unit exempted under s. NR 665.1083 (3) (a) from using air emission controls according to the 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(1)(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 hazardous waste stream is placed in a waste management unit exempted under s. NR 665.1083 (3) (a) from using air emission controls, and thereafter make an initial determination of the average VO concentration of the waste stream for each averaging period that a hazardous waste is managed in the unit. NR 665.1084(1)(a)2.2. Perform a new waste determination whenever changes to the source generating the waste stream are reasonably likely to cause the average VO concentration of the hazardous waste to increase to a level that is equal to or greater than the VO concentration limit in s. NR 665.1083 (3) (a). NR 665.1084(1)(b)(b) For a waste determination that is required by par. (a), determine the average VO concentration of a hazardous waste at the point of waste origination using either direct measurement as specified in par. (c) or by knowledge as specified in par. (d). NR 665.1084(1)(c)(c) If the owner or operator uses direct measurement to determine average VO concentration of a hazardous waste at the point of waste origination, the owner or operator shall do all of the following: NR 665.1084(1)(c)1.1. ‘Identification.’ Identify and record the point of waste origination for the hazardous waste. NR 665.1084(1)(c)2.2. ‘Sampling.’ Collect samples of the hazardous waste stream at the point of waste origination 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(1)(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 one year. NR 665.1084(1)(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 source or process generating the hazardous waste stream. Examples of the normal variations are seasonal variations in waste quantity or fluctuations in ambient temperature. NR 665.1084(1)(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, incorporated by reference in s. NR 660.11. NR 665.1084(1)(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 source or process generating the hazardous waste represented by the samples. NR 665.1084(1)(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(1)(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(1)(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, incorporated by reference in s. NR 660.11. 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. NR 665.1084(1)(c)4.a.a. Calculate the average VO concentration () on a mass-weighted basis using the results for all waste determinations conducted according to subds. 2. and 3. and the following equation: where:
= Average VO concentration of the hazardous waste at the point of waste origination on a mass-weighted basis, ppmw i = Individual waste determination “i” of the hazardous waste
n = Total number of waste determinations of the hazardous waste conducted for the averaging period (not to exceed 1 year)
Qi = Mass quantity of hazardous waste stream represented by Ci, kg/hr
QT = Total mass quantity of hazardous waste during the averaging period, kg/hr
Ci = Measured VO concentration of waste determination “i” determined according to subd. 3. (i.e. the average of the 4 or more samples specified in subd. 2. b.), ppmw
NR 665.1084(1)(c)4.b.b. For the purpose of determining Ci, for individual waste samples analyzed according to subd. 3., account for VO concentrations determined to be below the limit of detection of the analytical method by using the following VO concentration: 1) If Method 25D in appendix A of 40 CFR part 60, incorporated by reference in s. NR 660.11, is used for the analysis, one-half the blank value determined in the method at section 4.4 of Method 25D. 2) If any other analytical method is used, one-half the sum of the limits of detection established for each organic constituent in the waste that has a Henry’s law constant value 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.
NR 665.1084(1)(c)5.5. ‘Compliance determination.’ Provided that the test method is appropriate for the waste as required under subd. 3., the department shall determine compliance based on the test method used by the owner or operator recorded pursuant to s. 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:
