INSTRUCTIONS FOR EUD-1 

EMISSIONS UNIT DESCRIPTION FOR FUEL COMBUSTION SOURCES 

Use this form is to describe emissions units that combust solid or liquid fuels, such as boilers, steam generators, 

electric generators and the like. 

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. Enter 

the source classification code (SCC), if known or readily available (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 be critical to 

identifying the emissions unit and its applicable requirements. 

Section C - Describe the primary fuel type is that used during the majority of its operating hours. Your fuel 

supplier should be able to provide the information requested here. If the supplier provides a range of values, use 

the highest or worst-case value. Identify and describe any associated air pollution control device. If data 

provided by the vendor, attach documentation (if available); if other basis, indicate how determined (e.g., AP-42). 

Section D - Actual fuel usage will be used to calculate actual emissions for purposes of calculating fees. 

Maximum usage will be used to calculate PTE. If your fuel is a combination of several fuel types, indicate the 

average percentage of each fuel on an hourly and yearly basis in the appropriate column or on an attachment. 

The basis of this fuels usage data must be explained on an attachment. For example, actual fuel consumption 

could be established from purchase records or records of fuel consumption over the preceding calendar year or 

for sources that have not yet operated for a full year, from estimations of actual usage. 

Section E - Identify and describe any associated air pollution control device for the unit described above. For 

control efficiency, you may need to contact the vendor, if so, attach copies of correspondence from the vendor 

documenting these values, if available, or indicate how these values were otherwise determined. 

Section F - Complete this section only if ambient impact assessment is an applicable requirement or the facility is 

a temporary source. This is not common.
