(Values in parentheses indicate less than 75% available data for all 4 quarters)
* The rule for revised federal standards was signed in June 2010, providing a primary 1-hr standard of 75 ppb, and a secondary 3-hr standard of 0.5 ppm. However, the 1971 standards remain in effect until one year after an area is designated for the 2010 standard.
