Methods for Estimating Air Emissions From Feedlots Limited, EPA Advisers Say

摘要

The Environmental Protection Agency Science Advisory Board said in a draft report that the agency's air emissions-estimating methodologies for animal feeding operations are based on limited data and cannot be extrapolated to farms across the country. EPA based the methodologies on data from three facilities that raise meat chickens and nine swine and dairy facilities-only a fraction of the half million animal feeding operations in the country-and key variables cannot be applied nationwide, the Science Advisory Board said.
