Section 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 addon 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.Utah Admin.
