Universal Citation: WI Admin Code ยง NR 661.1032

Current through August 26, 2024

(1) A remanufacturer or other person that stores or treats hazardous secondary material in hazardous secondary material management units with process vents associated with distillation, fractionation, thin-film evaporation, solvent extraction, or air or steam stripping operations managing hazardous secondary material with organic concentrations of at least 10 ppmw shall do one of the following:

(a) Reduce total organic emissions from all affected process vents at the facility below 1.4 kg/h (3 lb/h) and 2.8 Mg/yr (3.1 tons/yr).

(b) Reduce, by use of a control device, total organic emissions from all affected process vents at the facility by 95 weight percent.

(2) If a remanufacturer or other person that stores or treats hazardous secondary material installs a closed-vent system and control device to comply with the provisions of sub. (1) the closed-vent system and control device shall meet the requirements specified in s. NR 661.1033.

(3) Determinations of vent emissions and emission reductions or total organic compound concentrations achieved by add-on control devices may be based on engineering calculations or performance tests. If performance tests are used to determine vent emissions, emission reductions, or total organic compound concentrations achieved by add-on control devices, the performance tests shall conform with the requirements specified in s. NR 661.1034(3).

(4) When a remanufacturer or other person that stores or treats hazardous secondary material and the department do not agree on determinations of vent emissions or emission reductions or total organic compound concentrations achieved by add-on control devices based on engineering calculations, the procedures specified in s. NR 661.1034(3) shall be used to resolve the disagreement.
