VOC1. Capture and carbon adsorption with 90% capture and 95% control of the manufacturing emissions1. Non-VOC blowing agents 2. Capture and carbon adsorption with 100% capture and 95% control of the pour heads, the oven/laminator and the trimming and sawing equipment 3.

Capture and carbon adsorption with 95% capture and 95% control of the pour heads, the oven/laminator and the trimming and sawing equipment


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.
