RE: State of Minnesota Recommendation of Attainment Designation for Ozone 

Dear Mr. Mathur: 

Pursuant to Section 107(d) of the Clean Air Act, and following the revision of the ozone National 

Ambient Air Quality Standard (NAAQS) on March 12,2008, the Governor of Minnesota is 

recommending that the entire state of Minnesota be designated as attainment for the ozone standard. This 

recommendation does not include areas in the state that are under tribal jurisdiction. Those tribal 

governments which have met eligibility determination and have submitted a Tribal Implementation Plan 

to the U.S. Environmental Protection Agency (EPA) may submit designation requests to EPA und,er the 

Tribal Authority Rule of 1998 (63 FR 7254). 

This designation recommendation is based on three consecutive years (2006-2008) of air sampling data 

collected at sixteen federal reference monitors around the state. The enclosed summary data provide the 

fourth highest value at each monitoring site for each year (1997-2008) and three-year calculated averages 

(1997-1999 through 2006-2008) for each site. No site in the state exceeded the eight-hour standard 

(0.075 parts per million) for ozone for any three-year period. Quality assured ozone monitoring data for 

Minnesota has been submitted to the Air Quality System through 2008. The locations of the ozone 

monitors in the state are identified on the enclosed map. 

The Commissioner of the Minnesota Pollution Control Agency is duly authorized by the Governor of the 

State of Minnesota to submit this letter on behalf of Governor Pawlenty. We anticipate that you will 

agree with this recommendation for state-wide attainment designation. 

If you have questions or comments on this submission, please contact Gordon Andersson of my staff at 

65 1-757-2197. 

Sincerely, 

J 

Paul Eger
