# Attainment Status Recommendation

Dear Administrator McGrath:

On December 14, 2012, 

# the United States Environmental Protection Agency

promulgated a revised primary annual PM

25 

# Nation

3 

# al Ambient Air Quality Standard. The

final rule sets the annual PM

25 

# standard at 12 

# [lg/m. As set forth in the final rule, EPA

requested that states submit their initial PM

25 

# designations to the agency no later than

December 13, 2013. 

# The North Dakota Department of Health operates an extensive network

of ambient air quality monitoring sites located across the state. Data collected from North

Dakota's extensive monitoring system forms the foundation for this recommendation. This

data has been entered into the Air Quality Subsystem (AQS) and the Department of Health

believes the monitoring data to be complete and accurate. Based on the monitoring data, it is

recommended that the entire State of North Dakota be designated as attainment for the

annual PM

25 

# standard.

If you have any questions, please contact the Division of Air Quality within the Health

Department at (701 )328-5 188.
