Emission Inventory
Reporting of Emissions
Facilities that hold air pollution control permits to operate may be
required to submit Annual
Emission Inventory Reports to the North Dakota Department of Health.
At the beginning of each year, the Department will send letters to the
sources 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. For details about permit-to-operate fees, see
Chapter 33-15-23,
of the North Dakota Air Pollution Control Rules.
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. The submitter should
use the methodology that results in the most accurate representation of
actual emissions.
