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.
NR 661.1083(1)(d)3.3. A remanufacturer or other person that stores or treats the hazardous secondary material using chemical constituent-specific concentration test data as the basis for knowledge of the hazardous secondary material may adjust the test data to the corresponding average VO concentration value that would have been obtained had the material 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, the measured concentration for each individual chemical constituent contained in the material is multiplied by the appropriate constituent-specific adjustment factor (fm25D).
NR 661.1083(1)(d)4.4. In the event that the department and the remanufacturer or other person that stores or treats the hazardous secondary material disagree on a determination of the average VO concentration for a hazardous secondary material stream using knowledge, then the results from a determination of average VO concentration using direct measurement as specified in par. (c) shall be used to establish compliance with the applicable requirements of this subchapter. The department may perform or request that the remanufacturer or other person that stores or treats the hazardous secondary material perform this determination using direct measurement. The remanufacturer or other person that stores or treats the hazardous secondary material may choose one or more appropriate methods to analyze each collected sample in accordance with the requirements specified in par. (c) 3.
NR 661.1083(3)(3)Procedure to determine the maximum organic vapor pressure of a hazardous secondary material in a tank.
NR 661.1083(3)(a)(a) A remanufacturer or other person that stores or treats hazardous secondary material shall determine the maximum organic vapor pressure for each hazardous secondary material placed in a tank using Tank Level 1 controls in accordance with standards specified in s. NR 661.1084 (3).
NR 661.1083(3)(b)(b) A remanufacturer or other person that stores or treats hazardous secondary material shall use either direct measurement as specified in par. (c) or knowledge of the waste as specified in par. (d) to determine the maximum organic vapor pressure that is representative of the hazardous secondary material composition stored or treated in the tank.
NR 661.1083(3)(c)(c) Direct measurement to determine the maximum organic vapor pressure of a hazardous secondary material shall be conducted using all of the following procedures:
NR 661.1083(3)(c)1.1. A sufficient number of samples shall be collected to be representative of the hazardous secondary material contained in the tank. 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 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 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(3)(c)2.2. Any appropriate one of the following methods may be used to analyze the samples and compute the maximum organic vapor pressure of the hazardous secondary material:
NR 661.1083(3)(c)2.a.a. Method 25E in appendix A of 40 CFR part 60, incorporated by reference in s. NR 660.11.
NR 661.1083(3)(c)2.b.b. Methods described in American Petroleum Institute Publication 2517, Third Edition, February 1989, “Evaporative Loss from External Floating-Roof Tanks,” incorporated by reference in s. NR 660.11.

NR 661.1083(3)(c)2.d.d. ASTM Method 2879-92, incorporated by reference in s. NR 660.11.
NR 661.1083(3)(c)2.e.e. Any other method approved by the department.
NR 661.1083(3)(d)(d) A remanufacturer or other person that stores or treats hazardous secondary material may use knowledge to determine the maximum organic vapor pressure of the hazardous secondary material. Documentation shall be prepared and recorded that presents the information used as the basis for the knowledge by the remanufacturer or other person that stores or treats the hazardous secondary material that the maximum organic vapor pressure of the hazardous secondary material is less than the maximum vapor pressure limit specified in s. NR 661.1084 (2) (a) 1. for the applicable tank design capacity category. An example of information that may be used is documentation that the hazardous secondary material is generated by a process for which at other locations it previously has been determined by direct measurement that the hazardous secondary material’s waste maximum organic vapor pressure is less than the maximum vapor pressure limit for the appropriate tank design capacity category.
NR 661.1083(4)(4)Procedure for determining no detectable organic emissions for the purpose of complying with this subchapter.
NR 661.1083(4)(a)(a) A remanufacturer or other person that stores or treats hazardous secondary material shall conduct a test to determine no detectable organic emissions for the purpose of complying with this chapter in accordance with the procedures specified in Method 21 in appendix A of 40 CFR part 60, incorporated by reference in s. NR 660.11. Each potential leak interface, a location where organic vapor leakage could occur, on the cover and associated closure devices shall be checked. Potential leak interfaces that are associated with covers and closure devices include the interface of the cover and its foundation mounting, the periphery of any opening on the cover and its associated closure device, and the sealing seat interface on a spring-loaded pressure relief valve.
NR 661.1083(4)(b)(b) The test shall be performed when the unit contains a hazardous secondary material having an organic concentration representative of the range of concentrations for the hazardous secondary material expected to be managed in the unit. During the test, the cover and closure devices shall be secured in the closed position.
NR 661.1083(4)(c)(c) The detection instrument shall meet the performance criteria of Method 21 in appendix A of 40 CFR part 60, incorporated by reference in s. NR 660.11, except the instrument response factor criteria in Section 3.1.2(a) of Method 21 shall be for the average composition of the organic constituents in the hazardous secondary material placed in the hazardous secondary management unit, not for each individual organic constituent.
NR 661.1083(4)(d)(d) The detection instrument shall be calibrated before use on each day of its use by the procedures specified in Method 21 in appendix A of 40 CFR part 60, incorporated by reference in s. NR 660.11.
NR 661.1083(4)(e)(e) Calibration gases shall be all of the following:
