Flexographic Printer - High-end graphics printing on Clay coated Paper, = or < 23 tons VOC/year
Pollutant Achieved in Practice or in the SIP Technologically Feasible Alternate Basic Equipment
VOCUsing materials with a VOC content, less water and exempt compounds, as indicated, or lower for metallic inks: 3.3 lb/gal for non-metallic inks: 1.0 lb/gal varnish: 0.63 lb/gal and practicing evaporation minimization methods, which include keeping all solvents and solvent-laden cloths/papers, not in active use, in closed containers.1. VOC Capture and thermal oxidation. 2. VOC Capture and thermal oxidation. 3. VOC Capture and carbon adsorption


BACT is the most stringent control technique for the emissions unit and class of source. Control techniques that are not achieved in practice or contained in s a state implementation plan must be cost effective as well as feasible. Economic analysis to demonstrate cost effectiveness is requried for all determinations that are not achieved in practice or contained in an EPA approved State Implementation Plan.

This is a Summary Page for this Class of Source. For background information, see Permit Specific BACT Determinations on Details Page.
