The acronym BACT stands for Best Available Control Technology.

• A. Best Available Contamination Tactics
• B. Best Available Control Technology
• C. Basic Aeration Control Technique
• D. Bacterial Activity Control Test

Answer: (B)

The concept being tested is the meaning and regulatory role of the acronym BACT. BACT stands for Best Available Control Technology, a permit standard used under environmental regulations to require the most effective emission control technology that is feasible for a given source and pollutant. This determination is made case by case, considering what technologies are technically achievable and economically reasonable, to achieve the greatest emission reductions for new or modified sources. The other phrases listed do not represent recognized regulatory terms: they describe unrelated ideas and are not used in the context of emission control standards.
