264.1032—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 of 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 paragraph (a) of this section the closed-vent system and control device must meet the requirements of  § 264.1033.
    
    
        
        (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 must conform with the requirements of  § 264.1034(c).
    
    
        
        (d) 
         When an owner or operator and the Regional Administrator do not agree on determinations of vent emissions and/or emission reductions or total organic compound concentrations achieved by add-on control devices based on engineering calculations, the procedures in  § 264.1034(c) shall be used to resolve the disagreement.
