Annual Emissions Inventory Report (AEIR)

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 operations during the previous year (January 1-December 31) and are due by March 15 unless a later date is specified in the permit.

Annual Production Reports are included in the AEIR reporting program.

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.

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:

AEIR Forms

AEIRs 1993 to Present

Reports from 1993 to present are in PDF, 2008 to present are also available as an Excel (.xls) file.

Annual Compliance Certification Report

The report is submitted annually within 45 days after December 31 by facilities operating under a major (Title V) permit to operate. The emissions units to be listed are identified by specific monitoring requirements by air contaminant, emission limit, monitoring method, and reporting requirements as listed in the permit to operate.

Semi-Annual Reports

The report is submitted semi-annually within 45 days after June 30 and December 31 by facilities operating under a major (Title V) permit to operate. The report lists deviations from monitoring requirements, and deviations from emission limits or parameters set by the operating permit during the reporting period. For facilities subject to compliance assurance monitoring (CAM), the report will list any CAM excursions or deviations for affected emission units.

EPA Reporting

For some regulations, the EPA and not the North Dakota Department of Health is the implementation and reporting agency. For reporting emissions and other records to EPA contact EPA Region 8 at:

    Director, Air & Radiation Program (8P-AR)
    U.S. EPA - Region 8
    1595 Wynkoop Street
    Denver, CO 80202-1129
