In August 2021, the U.S. Environmental Protection Agency (EPA) released draft models to estimate daily NH3, H2S, PM10, PM2.5, and TSP emissions from egg-layer houses (high-rise and manure-belt) and manure storage using inputs of daily mean ambient temperature, relative humidity (RH), and hen inventory. These models were developed from refined datasets generated by the National Air Emissions Monitoring Study fieldwork completed in 2009. Notably, they do not include data for cage-free housing. Currently, 66% of U.S. laying hens are housed in cages; thus, these models, if adopted, will have a substantial impact …

In August 2021, the U.S. Environmental Protection Agency( EPA) released draft models to estimate daily NH3, H2S, PM2.5, PM10, and total suspended particulate semissions from U.S. broiler operations using inputs of daily mean ambient temperature, relative humidity, and live animal weight. The EPA developed these models using data sets collected between 2005 and 2007. It is important to note that over 15 yr have passed since the original data were collected, and broiler genetics, nutrition, and management have improved consideably. These models, if adopted, could have substantial impact on the U.S. broiler industry regarding air emission management and regulation. The …
