Description:
The paper presents results from two new studies at swine finishing facilities. (NOTE: Concentrated animal feeding operations (CAFOs) are being examined in several regions of the U,.S. as major sources of ammonia and particulate matter precursors. EPA's National Risk Management Research Laboratory (NRMRL) has previously measured ammonia concentrations around, and estimated emissions from, a swine production facility). The new data were collected for tunnel-ventilated pull-plug swing finishing barns using chemiluminescent ammonia measurements from the exhaust fans. Open-path Fourier transform infrared (OP-FTIR) measurements of a naturally ventilated pit rechange barn and its lagoon are used to develop emission factors in the second study. The data suggest that the barns are a significant source of ammonia and that current emission factors are not markedly different from these new data.
