North Dakota Posts Emissions Inventory Reporting Requirements

April 1, 2013

North Dakota’s Department of Health/Air Quality has published important emission reporting requirements on the state’s Web site regarding its Annual Emissions Inventory Reporting (AEIR) process.

Reporting of Emissions 

Companies that have been issued an air pollution control permit to operate may be required to submit an Annual Emission Inventory Report (AEIR) to the North Dakota Department of Health.  At the beginning of each year, the Department will send letters to the company AEIR contact person responsible for submitting emission inventory reports.  The reports will address emissions during the previous year (January 1-December 31) and are due by March 15 unless a later date is specified in the permit.   (Click here to download emission inventory forms).

Uses of Emission Data 

Emission data are used to determine compliance with regard to emission limits and/or permit conditions; to identify emission levels, patterns, and trends; to serve as the basis for modeling of predicted pollutant concentrations in ambient air; to provide input for human health risk assessment studies; and to serve as a basis for determining annual permit-to-operate fees.

Methods of Calculation 

Emission inventories should be as accurate and complete as possible.  Emission data should be included for each significant unit/activity listed on the Air Pollution Control Permit to Operate for the installation.  The following methodologies can be used to determine emissions: (1) continuous emission monitors [CEMS], (2) source [stack] testing, (3) material balance, (4) emission factors [AP-42], (5) fuel analysis, (6) emission estimation models, or (7) engineering judgment.  Each report should be based on the methodology that results in the most accurate representation of actual emissions.

Annual emission inventory reports for years 1993-2011 are available on the agency’s Web site.

What this means to you

Operators in North Dakota are required to report their emissions inventory by March 15 for operations conducted the prior year for each activity listed on their permit and compliance to the permit levels.
