State Implementation Plan (SIP) - 2010 One-hour NO2 Standard

On Jan. 22, 2010, U.S. EPA strengthened the National Ambient Air Quality Standards (NAAQS) for nitrogen oxides as measured by nitrogen dioxide (NO2). U.S. EPA set a new one-hour primary NO2 standard at 100 ppb and retained the existing annual standard of 53 ppb (for which Ohio has been in full attainment). Ohio EPA will be preparing documents, which will be posted on this website, to address the new NO2 one-hour standard.
