Chapter NR 661

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.

NR 661.1034(5) (5) The determination that distillation, fractionation, thin-film evaporation, solvent extraction, or air or steam stripping operations manage hazardous secondary material with time-weighted, annual average total organic concentrations less than 10 ppmw shall be made by the remanufacturer or other person in accordance with all the following:

NR 661.1034(5)(a) (a) By the effective date that the facility becomes subject to the provisions of this subchapter or by the date when the material is first managed in a hazardous secondary material management unit, whichever is later.

NR 661.1034(5)(b) (b) Annually for continuously generated material, or whenever there is a change in the material being managed or a change in the process that generates or treats the material.

NR 661.1034(6) (6) When a remanufacturer or other person that stores or treats the hazardous secondary material and the department do not agree on whether a distillation, fractionation, thin-film evaporation, solvent extraction, or air or steam stripping operation manages a hazardous secondary material with organic concentrations of at least 10 ppmw based on knowledge of the material, the dispute may be resolved by using direct measurement as specified in sub. (4) (a).
