NR 661.1034(3)(a)6.6. Total organic emissions from all affected process vents at the facility shall be determined by summing the hourly total organic mass emission rates, Eh, as determined in subd. 4., and by summing the annual total organic mass emission rates, EA, as determined in subd. 5., for all affected process vents at the facility.

NR 661.1034(3)(b)(b) The remanufacturer or other person that stores or treats the hazardous secondary material shall record process information that may be necessary to determine the conditions of the performance tests. Operations during periods of startup, shutdown, and malfunction may not constitute representative conditions for the purpose of a performance test.

NR 661.1034(3)(c)(c) The remanufacturer or other person that stores or treats the hazardous secondary material at an affected facility shall provide, or cause to be provided, all of the following performance testing facilities:

NR 661.1034(3)(d)(d) For the purpose of making compliance determinations, the time-weighted average of the results of the 3 runs required in par. (a) 3. shall apply. In the event that a sample is accidentally lost or conditions occur in which one of the 3 runs must be discontinued because of forced shutdown, failure of an irreplaceable portion of the sample train, extreme meteorological conditions, or other circumstances beyond the control of the remanufacturer or other person that stores or treats the hazardous secondary material, compliance may, upon the department’s approval, be determined using the average of the results of the 2 other runs.

NR 661.1034(4)(4) To show that a process vent associated with a hazardous secondary material distillation, fractionation, thin-film evaporation, solvent extraction, or air or steam stripping operation is not subject to the requirements of this subchapter, the remanufacturer or other person that stores or treats the hazardous secondary material shall make an initial determination that the time-weighted, annual average total organic concentration of the material managed by the hazardous secondary material management unit is less than 10 ppmw using one of the following 2 methods:

NR 661.1034(4)(a)(a) Direct measurement of the organic concentration of the material using all of the following procedures:

NR 661.1034(4)(a)1.1. The remanufacturer or other person that stores or treats the hazardous secondary material shall take a minimum of 4 grab samples of material for each material stream managed in the affected unit under process conditions expected to cause the maximum material organic concentration.

NR 661.1034(4)(a)2.2. For material generated on-site, the grab samples shall be collected at a point before the material is exposed to the atmosphere such as in an enclosed pipe or other closed system that is used to transfer the material after generation to the first affected distillation, fractionation, thin-film evaporation, solvent extraction, or air or steam stripping operation. For material generated off-site, the grab samples shall be collected at the inlet to the first material management unit that receives the material, provided the material has been transferred to the facility in a closed system such as a tank truck and the material is not diluted or mixed with other material.

NR 661.1034(4)(a)3.3. Each sample shall be analyzed and the total organic concentration of the sample shall be computed using Method 9060A of “Test Methods for Evaluating Solid Waste, Physical/Chemical Methods,” EPA Publication SW-846, incorporated by reference in s. NR 660.11, or analyzed for its individual organic constituents.

NR 661.1034(4)(a)4.4. The arithmetic mean of the results of the analyses of the 4 samples shall apply for each material stream managed in the unit in determining the time-weighted, annual average total organic concentration of the material. The time-weighted average shall be calculated using the annual quantity of each material stream processed and the mean organic concentration of each material stream managed in the unit.

NR 661.1034(4)(b)(b) Using knowledge of the material to determine that its total organic concentration is less than 10 ppmw. Documentation of the material determination is required. Examples of documentation that shall be used to support a determination under this provision include production process information documenting that no organic compounds are used, information that the material is generated by a process that is identical to a process at the same or another facility that has previously been demonstrated by direct measurement to generate a material stream having a total organic content less than 10 ppmw, or prior speciation analysis results on the same material stream where it can also be documented that no process changes have occurred since that analysis that could affect the material total organic concentration.
