Notice: 2015 Annual Report

The North Dakota Department of Health (NDDoH) Division of Air Quality is soliciting public comment on its 2015 Ambient Air Quality Monitoring Program Annual Report. The report, which contains the annual Network Plan and Five Year Assessment with 2014 Data Summary, can be found on our Public Comments & Notices page.

Monitoring Network

Department of Health

The Air Quality Monitoring branch ensures that the ambient (outside) air quality in North Dakota is better than the levels required by the state per Chapter 33-15-02 and by the National Ambient Air Quality Standards . To address this responsibility, the Department owns and operates a network of eight ambient air quality monitoring sites stationed throughout the state.

National Park Service

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.

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 Department 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 These have now been superseded by the ability to generate custom time period data summaries.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 (
