The purpose of the Air Management Practices Assessment Tool (AMPAT) is to provide an objective overview of mitigation practices  best suited to address odor, emissions and dust at your livestock operation so that livestock and poultry producers may compare and narrow their options of mitigation techniques. Practices are divided into three categories by source: 1) Animal Housing; 2) Manure Storage & Handling; and 3) Land Application. Each mitigation practice has an individual page which includes a printable fact sheet and a short online slide presentation. There is a conservative estimate of the range in effectiveness for ammonia, hydrogen sulfide, dust, odor, volatile organic compounds, and greenhouse gases, and a relative cost (one, two, or three dollar signs). To obtain more information for any given practice, simply click on that practice.
