 Abstract:
The management of aerial pollutants is the next major
manure management issue that farmers face in the current
atmosphere of increased regulation. Aerial pollutants
including odor, particulate matter (PM), ammonia (NH3),
hydrogen sulfide (H2S), carbon dioxide (CO2), methane
(CH4) and nitrous oxide (N2O) emitted by concentrated
animal feeding operations (CAFOs) can create
neighborhood nuisance, animal or human health concerns,
or non-compliance with state or federal regulations.
Currently, an assessment of the true impact of these
Target Air Pollutants (TAPs) is limited by the lack of
reliable data on emission rates. This same lack of
information also hinders the development of air emission
control technologies, the use of computer modeling to
assess the impact of TAP emissions on ambient air
quality, and formation of practical federal and state
regulations.
 The project goal is to determine baseline TAP emission
rates for twelve types of animal confinement buildings
and evaluate the differences in emissions due to
geographical region, season of year, time of day,
building design, growth cycle of the animals, and
building management. Continuous emission and
environmental measurements will be taken at each
facility for five months.
Information from this research will provide producers,
technical assistance providers, regulators, and
compilers of emission inventories with accurate
information with which the U.S. can retain world
leadership on highly efficient animal agriculture, that
is consistent with rigorous environmental protection
requirements and rural socioeconomic needs. It directly
addresses the IFAFS topical area focusing on determining
and predicting odor, gas and particulate matter impacts
on the atmosphere and society.
