PM10Use of HVLP application equipment, or equivalent method.Enclosed spray booth, or equivalent, with particulate filters.
VOCUse of material(s) with a VOC content (less water and exempt compounds) as indicated, or lower: - For Glossy finish: 2.8 lb/gal - For Matte Finish: 1.7 lb/gal - For Waterproofing Sealer: 3.3 lb/gal and use of HVLP application equipment, or equivalent method, and a enclosed spray gun cleaner if using a VOC-containing solvent.1) Capture and control using an enclosed booth, or equivalent, and thermal incineration system. 2) Capture and control using an enclosed booth, or equivalent, and catalytic incineration system. and use of HVLP application equipment, or equivalent method, and a enclosed spray gun cleaner if using a VOC-containing solvent.


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.
