The Division of Air Quality has the primary responsibility for protecting the health and welfare of North Dakotans from the harmful effects of air pollution.

The Air Quality Monitoring branch ensures that the ambient (outside) air quality in North Dakota is better than the levels required by the state and federal Ambient Air Quality Standards. To address this responsibility, the Department owns and operates a network of eight ambient air quality monitors throughout the state.

As part of their national monitoring network, the National Park Service has installed an ambient monitoring site at Theodore Roosevelt National Park - South Unit. The Department operates various monitoring equipment at this site on their behalf.

In addition to the ambient air quality monitoring sites operated by the Department, the owners of certain industrial sources of air emissions also operate air quality monitoring sites within their immediate spheres of influence. The site locations selected are based on computer dispersion modeling and prevailing wind directions.

Each year the Department prepares an annual report on the ambient air quality data compiled for the previous calendar year. These and other periodic reports can be found via the links below.

The reports below were prepared specifically for two-sided printing.  Therefore, blank pages will occur in single-sided printed version. 

All reports require Adobe Acrobat Reader for viewing.

Annual Reports

Each year, the Department compiles a report summarizing the ambient air quality data obtained from the network of air quality monitoring sites in the state during the previous year. The reports include sulfur dioxide, nitrogen dioxide, ozone, ammonia, hydrogen sulfide, and particulate matter ambient air quality data. Online versions of each report from 1995 to present are available by selecting the desired year in the drop-down menu, below. A printed or electronic copy of a given report may be requested by contacting the North Dakota Department of Health Ambient Air Quality Monitoring Program at 701.328.5188

For a number of years, in addition to the annual report, the Department also published quarterly reports. These have now been superseded by the ability to generate custom time period data summaries. These summaries can cover historical periods (including those covered by the quarterly reports) up until the present.

A custom summary can be requested by calling 701.328.5188 or emailing Ryan Mills
