TUCKER, Ga. — Sixteen years ago, the animal agriculture industry entered into a voluntary Air Compliance Agreement (ACA) that had the stated goals of reducing air pollution, monitoring air emissions from farms that raise animals and promoting a national consensus on methods to estimate air emissions from these same farms.
The agreement required animal feeding operations to fund a study to monitor emissions from animal housing structures, manure storage facilities and manure treatment facilities. After finalizing the ACA, a study, titled the “National Air Emission Monitoring Study” or NAEMS, began collecting data at 25 farms that housed animals for agricultural production. . .
