STATE IMPLEMENTATION PLANS (SIP)

2010 1-hour NO2 Standard

On January 22, 2010, U.S. EPA strengthened the NAAQS for nitrogen oxides as measured by nitrogen dioxide  (NO2). U.S. EPA set a new 1-hour primary NO2 standard at 100 ppb and retained the existing annual standard of 53 ppb (for which Ohio has been in full attainment). In the near future, Ohio EPA will be preparing documents, which will be posted on this website, to address the new NO2 1-hour standard.
