Pollutant Achieved in Practice or in the SIP Technologically Feasible Alternate Basic Equipment
PM10HVLP application equipment.Enclosed spray booth with dry filters and the use of HVLP application equipment.
VOCUse of Coating compliant with Rule 4605, HVLP application equipment, and an enclosed gun cleaner, or equal.1. 98% control (Capture and control with thermal or catalytic oxidizer, or equal). 2. 95% control (Capture and control with carbon adsorption, or equal).


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.
