Best Available Control Technology (BACT ) Guideline 4.8.18
Last Update: 10/7/2001

Expanded Polystyrene Foam Products - Vertical, water-quenched extruder; food-grade products.
Pollutant Achieved in Practice or in the SIP Technologically Feasible Alternate Basic Equipment
VOCTotal emissions* of 0.94 lb VOC/100 lb of raw material processed.Total emissions* not to exceed 0.48 lb VOC/100 lb of raw material processed.Use of 100% HFC 152a or HFC-152 and CO2 mixture, or equal.
* Total emissions: Amount of the VOC added as a blowing agent less VOC retained in the produce and less any VOC collected and destroyed.

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.
