INSTRUCTIONS FOR EUD-2

EMISSIONS UNIT DESCRIPTION FOR VOC EMITTING SOURCES

Use this form to describe emissions units that us e, process, store or produce substances containing

VOC and that primarily emit VOC, such as painting or coating operations and printers.

In addition, this form may also be useful for certain HAP emitting sources. The purpose of this form is

to help you collect and organize technical data, including operational characteristics, applicable

requirements, compliance terms, and emissions.

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 from that used to describe the facility

as a whole. In addition, enter 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 - Identify and describe any associated air pollution control device for the unit described

above. If data (such as control efficiency) provided by the vendor, attach documentation (if available);

If other basis, indicate how determined (e.g., AP-42).

Section D - Complete this section only if ambient impact assessment is an applicable requirement or

the facility is a temporary source. This is not common.

Section E - VOC content and usage values are typically used to calculate emissions. Actual usage

will be multiplied by VOC content to calculate actual emissions, while maximum usage will be

multiplied by VOC content to calculate PTE. Explain the basis for the usage and VOC content values

on an attachment (e.g., material safety data sheet or MSDS). Also, EPA Reference Method 24 of 40

CFR Part 60, Appendix A, can also be used to determine VOC content but this is not required solely

for these application purposes. When VOC Content is determined through testing or calculation by the

applicant, the applicant must attach test data and calculations.
