What concerns EPA about emissions on AFOs?
Currently, EPA considers emissions from AFO barns, lagoons and retention ponds subject to the air laws if emissions are above established pollutant thresholds. A 2002 report by the National Academy of Sciences called on EPA to improve its method for estimating emissions from AFOs – a key step in mitigating air pollution from those operations. EPA needs better data to determine which AFOs meet or exceed these thresholds – i.e. the purpose of the study.
