    "1. A pollutant determined to be hazardous to human health and regulated under EPA's National Ambient Air Quality Standards. The 1970 amendments to the Clean Air Act require EPA to describe the health and welfare impacts of a pollutant as the \"criteria\" for inclusion in the regulatory regime. In the report, emissions of the criteria pollutants CO, NOx, NMVOCs, and SO₂ are reported because they are thought to be precursors to greenhouse gas formation.\n\n2. The 1970 amendments to the Clean Air Act required EPA to set National Ambient Air Quality Standards for certain pollutants known to be hazardous to human health. EPA has identified and set standards to protect human health and welfare for six pollutants: ozone, carbon monoxide, total suspended particulates, sulfur dioxide, lead, and nitrogen oxide. The term, \"criteria pollutants\" derives from the requirement that EPA must describe the characteristics and potential health and welfare effects of these pollutants. It is on the basis of the criteria that standards are set or revised.\n\n3. A group of six widespread and common air pollutants that EPA regulates on the basis of standards set to protect public health or the environment. The six criteria pollutants are carbon monoxide, lead, nitrogen dioxide, ozone, particulate matter, and sulfur dioxide.\n\n4. Emissions of NOX, HC, PM, and CO. Note that these pollutants are also sometimes described collectively as “non-greenhouse gas pollutants”, although they do not necessarily have negligible global warming potentials.\n\n5. Any pollutant for which there is established a NAAQS at 40 CFR part 50.\n\n6. Group of six widespread and common air pollutants that EPA regulates on the basis of standards set to protect public health or the environment (see National Ambient Air Quality Standards). The six criteria pollutants are carbon monoxide, lead, nitrogen dioxide, ozone, particulate matter, and sulfur dioxide.\n\n7. The Clean Air Act requires EPA to set National Ambient Air Quality Standards for six common air pollutants. These common air pollutants are found all over the United States. They are particle pollution (often referred to as particulate matter), ground-level ozone, carbon monoxide, sulfur oxides, nitrogen oxides and lead. These pollutants can harm human health and the environment, and cause property damage. Of the six pollutants, particle pollution and ground-level ozone are the most widespread health threats. EPA calls these pollutants \"criteria\" air pollutants because it regulates them by developing human health-based and/or environmentally based criteria (science-based guidelines) for setting permissible levels. The set of limits based on human health is called primary standards. Another set of limits intended to prevent environmental and property damage is called secondary standards.\n\n8. One of the six pollutants for which EPA is required to set National Ambient Air Quality Standards to protect human health and welfare. Criteria pollutants include ozone (ground-level), carbon monoxide, particulate matter, sulfur dioxide, lead, and nitrogen oxides. They are called \"criteria\" pollutants because the Clean Air Act required EPA to describe the criteria for setting or revising standards.\n\n9. Group of common air pollutants defined by EPA whose concentrations in the ambient air must be maintained at low levels to protect public health. EPA has promulgated a National Ambient Air Quality Standard (NAAQS) for each of the criteria pollutants.",
