Re: Annual PM25 Attainment Status Recommendation 

Dear Administrator McGrath: 

On December 14, 2012, the United States Environmental Protection Agency 

promulgated a revised primary annual PM25 Nation3

al Ambient Air Quality Standard. The 

final rule sets the annual PM25 standard at 12 [lg/m. As set forth in the final rule, EPA 

requested that states submit their initial PM25 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 PM25 standard. 

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

Department at (701 )328-5 188.
