NR 661.1083(1)(a)1.1. Make an initial determination of the average VO concentration of the material stream before the first time any portion of the material in the hazardous secondary material stream is placed in a hazardous secondary material management unit exempted under the provisions of s. NR 661.1082 (3) from using air emission controls, and thereafter make an initial determination of the average VO concentration of the material stream for each averaging period that a hazardous secondary material is managed in the unit.
NR 661.1083(1)(a)2.2. Perform a new material determination whenever changes to the source generating the material stream are reasonably likely to cause the average VO concentration of the hazardous secondary material to increase to a level that is equal to or greater than the applicable VO concentration limits specified in s. NR 661.1082.
NR 661.1083(1)(b)(b) Determination of average VO concentration using direct measurement or knowledge. For a material determination that is required under par. (a), the average VO concentration of a hazardous secondary material at the point of material origination shall be determined using either direct measurement as specified in par. (c) or by knowledge as specified in par. (d).
NR 661.1083(1)(c)(c) Direct measurement to determine average VO concentration of a hazardous secondary material at the point of material origination.
NR 661.1083(1)(c)1.1. ‘Identification.’ The remanufacturer or other person that stores or treats the hazardous secondary material shall identify and record in a log that is kept at the facility the point of material origination for the hazardous secondary material.
NR 661.1083(1)(c)2.2. ‘Sampling.’ Samples of the hazardous secondary material stream shall be collected at the point of material origination in a manner such that volatilization of organics contained in the material and in the subsequent sample is minimized and an adequately representative sample is collected and maintained for analysis by the selected method.The remanufacturer or other person that samples the hazardous secondary material shall sample according to all of the following:
NR 661.1083(1)(c)2.a.a. The averaging period to be used for determining the average VO concentration for the hazardous secondary material stream on a mass-weighted average basis shall be designated and recorded. The averaging period can represent any time interval that the remanufacturer or other person that stores or treats the hazardous secondary material determines is appropriate for the hazardous secondary material stream but may not exceed one year.
NR 661.1083(1)(c)2.b.b. A sufficient number of samples, but no less than 4 samples, shall be collected and analyzed for a hazardous secondary material determination. All of the samples for a given material determination shall be collected within a one-hour period. The average of the 4 or more sample results constitutes a material determination for the material stream. One or more material determinations may be required to represent the complete range of material 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 secondary material stream. Examples of such normal variations are seasonal variations in material quantity or fluctuations in ambient temperature.
NR 661.1083(1)(c)2.c.c. All samples shall be collected and handled in accordance with written procedures prepared by the remanufacturer or other person that stores or treats the hazardous secondary material and documented in a site sampling plan. This plan shall describe the procedure by which representative samples of the hazardous secondary material stream are collected such that a minimum loss of organics occurs throughout the sample collection and handling process, and by which sample integrity is maintained. A copy of the written sampling plan shall be maintained at the facility. 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 661.1083(1)(c)2.d.d. Sufficient information, as specified in the site sampling plan required under subd. 2. c., shall be prepared and recorded to document the material quantity represented by the samples and, as applicable, the operating conditions for the source or process generating the hazardous secondary material represented by the samples.
NR 661.1083(1)(c)3.3. ‘Analysis.’ Each collected sample shall be prepared and analyzed in accordance with Method 25D in appendix A of 40 CFR part 60, incorporated by reference in s. NR 660.11, 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 material concentration accounts for and reflects all organic compounds in the material with Henry’s law constant values 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 discretion of the remanufacturer or other person that stores or treats the hazardous secondary material, the test data obtained may be adjusted by any appropriate method to discount any contribution to the total volatile organic concentration that is a result of including a compound with 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 material is multiplied by the appropriate constituent-specific adjustment factor (fm25D). If the remanufacturer or other person that stores or treats the hazardous secondary material elects to adjust the 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 material. 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 specified in subd. 3. a. or b. and provided the requirement to reflect all organic compounds in the material with Henry’s law constant values greater than or equal to 0.1 Y/X, which can also be expressed as 1.8 x 10-6atmospheres/gram-mole/m3 at 25°C, is met.
NR 661.1083(1)(c)3.a.a. Any EPA standard method that has been validated in accordance with “Alternative Validation Procedure for EPA Waste and Wastewater Methods,” appendix D of 40 CFR part 63, incorporated by reference in s. NR 660.11.
NR 661.1083(1)(c)3.b.b. Any other analysis method that has been validated in accordance with 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 661.1083(1)(c)4.4. ‘Calculations.’
NR 661.1083(1)(c)4.a.a. The average VO concentration (C) on a mass-weighted basis shall be calculated by using the results for all material determinations conducted in accordance with subds. 2. and 3. and the following equation:
Where:
C = Average VO concentration of the hazardous secondary material at the point of material origination on a mass-weighted basis, ppmw.
i = Individual material determination “i” of the hazardous secondary material.
n = Total number of material determinations of the hazardous secondary material conducted for the averaging period (not to exceed 1 year).
Q= Mass quantity of hazardous secondary material stream represented by Ci, kg/hr.
Q= Total mass quantity of hazardous secondary material during the averaging period, kg/hr.
C= Measured VO concentration of material determination “i” as determined in accordance with the requirements specified in subd. 3., which is the average of the 4 or more samples specified in subd. 2. b., ppmw.
NR 661.1083(1)(c)4.b.b. For the purpose of determining Ci, for individual material samples analyzed in accordance with subd. 3., the remanufacturer or other person that stores or treats the hazardous secondary material shall 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 in appendix A of 40 CFR part 60.
2) If any other analytical method is used, one-half the sum of the limits of detection established for each organic constituent in the material that has a Henry’s law constant values 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 10-6atmospheres/gram-mole/m3 , at 25°C.
NR 661.1083(1)(d)(d) Use of knowledge by the remanufacturer or other person that stores or treats the hazardous secondary material to determine average VO concentration of a hazardous secondary material at the point of material origination.
NR 661.1083(1)(d)1.1. The remanufacturer or other person that stores or treats the hazardous secondary material shall prepare documentation that presents the information used as the basis for the knowledge of the hazardous secondary material 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 secondary material stream; constituent-specific chemical test data for the hazardous secondary material stream from previous testing that are still applicable to the current material stream; previous test data for other locations managing the same type of material stream; or other knowledge based on information included in shipping papers or material certification notices.
NR 661.1083(1)(d)2.2. If test data are used as the basis for knowledge, then the remanufacturer or other person that stores or treats the hazardous secondary material shall 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, a remanufacturer or other person that stores or treats the hazardous secondary material may use organic concentration test data for the hazardous secondary material stream that are validated in accordance with 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.
