R315-265-1032. Air Emission Standards for Process Vents--Standards: Process Vents

(a) The owner or operator of a facility with process vents associated with distillation, fractionation, thin-film evaporation, solvent extraction or air or steam stripping operations managing hazardous wastes with organic concentrations at least 10 ppmw shall either: (1) 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, or (2) Reduce, by use of a control device, total organic emissions from all affected process vents at the facility by 95 weight percent. (b) If the owner or operator installs a closed-vent system and control device to comply with the provisions of Subsection R315-265-1032(a), the closed-vent system and control device shall meet the requirements of Section R315-265-1033. (c) 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 of Subsection R315-265-1034(c). (d) If an owner or operator and the Director do not agree on determinations of vent emissions and emission reductions or both or total organic compound concentrations achieved by add-on control devices based on engineering calculations, the test methods in Subsection R315-265-1034(c) shall be used to resolve the disagreement.
