Material determination procedures

1. Material determination procedure to determine average volatile organic (VO) concentration of a hazardous secondary material at the point of material origination. a. A remanufacturer or other person that stores or treats the hazardous secondary material shall determine the average VO concentration at the point of material origination for each hazardous secondary material placed in a hazardous secondary material management unit exempted under the provisions of subdivision a of subsection 3 of section 33.1-24-02-202 from using air emission controls in accordance with standards specified in sections 33.1-24-02-204 through 33.1-24-02-207, as applicable to the hazardous secondary material management unit. (1) An initial determination of the average VO concentration of the material stream must be made 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 subdivision a of subsection 3 of section 33.1-24-02-202 from using air emission controls, and thereafter an initial determination of the average VO concentration of the material stream must be made for each averaging period that a hazardous secondary material is managed in the unit; and (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 section 33.1-24-02-202. b. For a material determination that is required by subdivision a, the average VO concentration of a hazardous secondary material at the point of material origination must be determined using either direct measurement as specified in subdivision c or by knowledge as specified in subdivision d. c. Direct measurement to determine average VO concentration of a hazardous secondary material at the point of material origination. (1) Identification. The remanufacturer or other person that stores or teats 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. (2) Sampling. Samples of the hazardous secondary material stream must 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. (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 must 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. (b) A sufficient number of samples, but no less than four samples, must be collected and analyzed for a hazardous secondary material determination. All of the samples for a given material determination must be collected within a one-hour period. The average of the four 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. (c) All samples must 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 must 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 must 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 40 CFR part 60, appendix A. (d) Sufficient information, as specified in the "site sampling plan" required under subparagraph c, must 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. (3) Analysis. Each collected sample must be prepared and analyzed in accordance with Method 25D in 40 CFR part 60, appendix A 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 1.8x10-6 atmospheres/gram-mole/meters3] at twenty-five degrees Celsius. 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 twenty-five degrees Celsius. 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 must be made to all individual chemical constituents with a Henry's law constant value greater than or equal to 0.1 Y/X at twenty-five degrees Celsius 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 in subparagraph 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 1.8x10-6 atmospheres/gram-mole/meters3] at twenty-five degrees Celsius, is met. (a) Any environmental protection agency standard method that has been validated in accordance with "Alternative Validation Procedure for EPA Waste and Wastewater Methods," 40 CFR part 63, appendix D. (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 40 CFR part 63, appendix A. 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. (4) Calculations. (a) The average VO concentration ( ) on a mass-weighted basis must be calculated by using the results for all material determinations conducted in accordance with paragraphs 2 and 3 and the following equation: where: = Average VO concentration of the hazardous secondary material at the point of material origination on a mass-weighted basis, parts per million weight. 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 one year). Qi = Mass quantity of hazardous secondary material stream represented by Ci, kilograms per hour. QT = Total mass quantity of hazardous secondary material during the averaging period, kilogram per hour. Ci = Measured VO concentration of material determination "i" as determined in accordance with the requirements of paragraph 3 (for example, the average of the four or more samples specified in subparagraph b of paragraph 2), parts per million weight. (b) For the purpose of determining Ci, for individual material samples analyzed in accordance with paragraph 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 40 CFR part 60, appendix A is used for the analysis, one-half the blank value determined in the method at Section 4.4 of Method 25D in 40 CFR part 60, appendix A. [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 1.8x10-6 atmospheres/gram-mole/meter3] at twenty-five degrees Celsius. 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. (1) Documentation must be prepared 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 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 which 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. (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 which are validated in accordance with Method 301 in 40 CFR part 63, appendix A as the basis for knowledge of the material. (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 which would have been obtained had the material samples been analyzed using Method 25D in 40 CFR part 60, appendix A. 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). (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 subdivision c shall be used to establish compliance with the applicable requirements of sections 33.1-24-02-200 through 33.1-24-02-214. 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 of paragraph 3 of subdivision c. 2. [Reserved]. 3. Procedure to determine the maximum organic vapor pressure of a hazardous secondary material in a tank. a. A remanufacturer or other person that stores or treats the 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 subsection 3 of section 33.1-24-02-204. b. A remanufacturer or other person that stores or treats the hazardous secondary material shall use either direct measurement as specified in subdivision c or knowledge of the waste as specified by subdivision d to determine the maximum organic vapor pressure which is representative of the hazardous secondary material composition stored or treated in the tank. c. Direct measurement to determine the maximum organic vapor pressure of a hazardous secondary material. (1) Sampling. A sufficient number of samples must be collected to be representative of the hazardous secondary material contained in the tank. All samples must 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 must 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 must be maintained at the facility. An example of acceptable sample collection and handling procedures may be found in Method 25D in 40 CFR part 60, appendix A. (2) Analysis. Any one of the following appropriate methods may be used to analyze the samples and compute the maximum organic vapor pressure of the hazardous secondary material: (a) Method 25E in 40 CFR part 60, appendix A; (b) Methods described in American Petroleum Institute Publication 2517, Third Edition, February 1989, "Evaporative Loss from External Floating-Roof Tanks," (as incorporated by reference in section 33.1-24-01-05); (c) Methods obtained from standard reference texts; (d) ASTM Method 2879-92 (as incorporated by reference in section 33.1-24-01-05); and (e) Any other method approved by the department. d. Use of knowledge to determine the maximum organic vapor pressure of the hazardous secondary material. Documentation must 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 listed in paragraph 1 of subdivision a of subsection 2 of section 33.1-24-02-204 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. 4. Procedure for determining no detectable organic emissions for the purpose of complying with sections 33.1-24-02-200 through 33.1-24-02-214: a. The test must be conducted in accordance with the procedures specified in Method 21 of 40 CFR part 60, appendix A. Each potential leak interface (for example, a location where organic vapor leakage could occur) on the cover and associated closure devices must 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. b. The test must 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 must be secured in the closed position. c. The detection instrument must meet the performance criteria of Method 21 of 40 CFR part 60, appendix A, except the instrument response factor criteria in Section 3.1.2(a) of Method 21 must 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. d. The detection instrument must be calibrated before use on each day of its use by the procedures specified in Method 21 of 40 CFR part 60, appendix A. e. Calibration gases must be as follows: (1) Zero air (less than ten parts per million volume hydrocarbon in air); and (2) A mixture of methane or n-hexane and air at a concentration of approximately, but less than, ten thousand parts per million volume methane or n-hexane. f. The background level must be determined according to the procedures in Method 21 of 40 CFR part 60, appendix A. g. Each potential leak interface must be checked by traversing the instrument probe around the potential leak interface as close to the interface as possible, as described in Method 21 of 40 CFR part 60, appendix A. 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 must 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 (for example, some pressure relief devices), the instrument probe inlet must be placed at approximately the center of the exhaust area to the atmosphere. h. The arithmetic difference between the maximum organic concentration indicated by the instrument and the background level must be compared with the value of five hundred parts per million volume except when monitoring a seal around a rotating shaft that passes through a cover opening, in which case the comparison must be as specified in subdivision i. If the difference is less than five hundred parts per million volume, then the potential leak interface is determined to operate with no detectable organic emissions. 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 must be compared with the value of ten thousand parts per million weight. If the difference is less than ten thousand parts per million weight, then the potential leak interface is determined to operate with no detectable organic emissions.
