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 oper ational 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 fo rm that used for the facility as a whole. In addition,

complete the Source Classification Code (SCC), if k nown 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 attach ments. 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.
