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.c.c. Methods obtained from standard reference texts.
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:
NR 661.1083(4)(e)1.1. Zero air that is less than 10 ppmv hydrocarbon in air.
NR 661.1083(4)(e)2.2. A mixture of methane or n-hexane and air at a concentration of approximately, but less than, 10,000 ppmv methane or n-hexane.
NR 661.1083(4)(f)(f) The background level shall be determined according to the procedures in Method 21 in appendix A of 40 CFR part 60, incorporated by reference in s. NR 660.11.
NR 661.1083(4)(g)(g) Each potential leak interface shall be checked by traversing the instrument probe around the potential leak interface as close to the interface as possible, as described in Method 21 in appendix A of 40 CFR part 60, incorporated by reference in s. NR 660.11. In the case when the configuration of the cover or closure device prevents a complete traverse of the interface, all accessible portions of the interface shall be sampled. In the case when the configuration of the closure device prevents any sampling at the interface and the device is equipped with an enclosed extension or horn, such as some pressure relief devices, the instrument probe inlet shall be placed at approximately the center of the exhaust area to the atmosphere.
NR 661.1083(4)(h)(h) The arithmetic difference between the maximum organic concentration indicated by the instrument and the background level shall be compared with the value of 500 ppmv except when monitoring a seal around a rotating shaft that passes through a cover opening, in which case the comparison shall be as specified in par. (i). If the difference is less than 500 ppmv, then the potential leak interface is determined to operate with no detectable organic emissions.
NR 661.1083(4)(i)(i) For the seals around a rotating shaft that passes through a cover opening, the arithmetic difference between the maximum organic concentration indicated by the instrument and the background level shall be compared with the value of 10,000 ppmw. If the difference is less than 10,000 ppmw, then the potential leak interface is determined to operate with no detectable organic emissions.
