In 1963, a typical car—which ran on leaded gasoline without pollution control devices— emitted 520 pounds of hydrocarbons, 1,700 pounds of carbon monoxide, and 90 pounds of nitrogen oxide every 10,000 miles traveled. Even so, cars and trucks are still making us sick—and killing us.

States and local air quality regulators have the legal authority to set particulate matter (PM), ozone, and nitrogen oxides (NOx) emissions standards and adopt regulations for these pollutants when they are already in attainment of the national ambient air quality standards ( NAAQS ) set by the U.S.

One of the most significant air quality challenges in the Basin is reducing emissions of the ozone precursor nitrogen oxides (NO x ) to meet the ozone standard attainment deadlines. According to the 2016 AQMP, mobile sources contributed about 88% of total NO x emissions in the Basin in 2012.

The transportation sector is also a substantial source of nitrogen oxides and particulates, both of which are dangerous to human health. EPA is an effort by conservative states and fuel suppliers to block EPA regulations of greenhouse gas emissions from motor vehicles under the Clean Air Act. Q: Hi, Sean.
