Emissions Testing

Measuring emissions of air contaminants may be referred to as emissions testing, source testing, stack testing or performance testing. The North Dakota Department of Health requires testing at a variety of sources to ensure that specific emission limits are being met and to ensure compliance with the North Dakota Air Pollution Control Rules. These tests are conducted in accordance with procedures approved or specified by the Department.

If you have an issued Permit to Construct or Permit to Operate, please address questions to your facility's state Compliance Manager (see Permit Portal for your state contact).

Questions may be addressed to the North Dakota Department of Health at 701.328.5188 or email Keith Hinnenkamp (khinnenk@nd.gov).


Tests are normally performed by independent testing companies with expertise in the applicable test method(s) being conducted. The Department must be notified at least 30 days prior to testing to allow sufficient time for:

  • A Department review of the proposed test procedures and, if necessary, a test site inspection.
  • A pre-test meeting with Department staff, (if necessary).
  • Scheduling a Department representative to observe the performance test.
Each facility is assigned a DoAQ staff member for handling compliance questions and reporting review. The contact can be found through our Permit Portal.

The Department generally requires that testing be conducted in accordance with methodology promulgated by the Environmental Protection Agency in the Code of Federal Regulations (CFR). Alternative methods or deviations from a promulgated method must receive approval prior to the test. A complete listing of test methods is available under EPAs bulletin board system at https://www.epa.gov/emc .


The Department has developed a Standard Operating Procedure for the use of portable analyzers.
