In 1971, the U.S. Environmental Protection Agency (EPA) first set National Ambient Air Quality Standards (NAAQS) for CO. EPA set an 8-hour primary NAAQS at 9 parts per million (ppm) and a 1hour primary NAAQS at 35 ppm (see table below). All CO areas are currently meeting the NAAQS and have approved maintenance plans.
