Best Available Control Technology

Best Available Control Technology (BACT) is an emission limitation based on the maximum degree of reduction for each regulated air pollutant emitted from or that results from any new or modified stationary source. BACT is the emission rates that are achievable for a source or modification, determined on a case-by-case basis and taking into account energy, environmental and economic impacts, and other costs.
