INSTRUCTIONS FOR EUD-3
EMISSIONS UNIT DESCRIPTION FOR PROCESS SOURCES

This form is designed to describe emissions units for processes for which forms EUD-1 or EUD-2 are not
appropriate. For example, sources such as rock crushers and asphalt batch plants. This form will help you to
collect and organize technical information, including operational characteristics, applicable requirements,
compliance terms, and emissions for each emissions unit.
Section A - The emissions unit ID should be consistent with the one used in section I of form GIS. Enter the
four-digit SIC code for the unit, which may be different form that used for the facility as a whole. In addition,
complete the Source Classification Code (SCC), if known or available, but this is not mandatory.
Section B - There may be other information that the permitting authority will need to know that is not specifically
requested on the forms and that should be included on attachments. Such information would include information
needed to adequately identify the emissions unit and to determine its applicable requirements.
Section C - The amount of raw materials that are processed and/or the number of activities performed are
values that are typically multiplied by emissions factors to calculate PTE and actual emissions.
Section D - Identify and describe any associated air pollution control device. Attach copies of correspondence
from the vendor documenting these values, if available, or indicate how these values were otherwise determined
(e.g., AP-42).
Section E - Complete this section only if ambient impact assessment is an applicable requirement or the facility is
a temporary source. This is not common.
