Region 1: EPA New England

MAINE

For 1999 and after, click on the date for the corresponding eight-hour average peak ozone map for that day.

In March 2008, EPA revised the 8-hour ozone standard and changed the Air Quality Index (AQI) to align with this new standard. Maps for days in 2007 and earlier are based on the 1997 8-hour ozone standard. Maps for 2008 are based on the new 2008 ozone standard and the revised AQI. Click Here for a table showing the revised AQI breakpoints for the 2008 ozone standard.
