Best Available Control Technology (BACT ) Guideline 2.2.3
Last Update: 6/28/2004


Cheese Wastewater Digester
Pollutant Achieved in Practice or in the SIP Technologically Feasible Alternate Basic Equipment
NOx1. Ultra low-NOx flare with NOx emissions <= 0.03 lb/MMBtu 2. Enclosed flare and NOx emission <= 0.06 lb/MMBtu 3. IC engine with NOx emissions <= 50 ppmvd @ 15% O2 (<= 0.18 lb/MMBtu)
PM101. Smokeless combustion and natural gas or LPG fired pilot
SOx1. 99% H2S removal (dry or wet scrubber) 2. 90% H2S removal (chemical addition or iron sponge scrubber) 3. Water scrubber or 80% H2S removal


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.
