How to Select an SCC?


In CEIDARS SCCs are used as a primary
identifying data element in Process
Table
Match SCC Description with Process
Description and Process Rate Units

Organization of SICs




SIC codes are use to describe the type of
activity that occurs at facility
Major Economic Sectors (Agriculture, Mining,
Construction, Manufacturing, Transportation,
Wholesale Trades, Retail Trades, Finance,
Services, and Public Administration)

Facility vs. Process SIC



In CEIDARS SICs are used on two levels
in Facility Table and in Process Table
Facility SIC Identifies Primary Activity of
Entire Facility
Process SIC Identifies Type of Activity
for a Specific Process

Organization of EICs
Four levels of identification:
 Level I - Summary Category (Electric Utilities,
Industrial Processes, etc.)
 Level II – Source Category (Boilers, Landfills,
Farming Operations, etc.)
 Level III – Materials (Diesel, Wood, Dust,
etc.)
 Level IV – Sub-Category

EIC and Valid SCC/SIC




EIC is assigned to each valid SCC/SIC
combination
New combinations are assigned upon positive
verification
Combination is not valid if SCC does not exist,
SIC does not exist or SCC & SIC are not both
for the same process type (commercial or
industrial)
In CEIDARS there are ~50,000 valid SCC/SIC
combinations

Steps in Assigning an SCC/SIC



Assign an SIC and NAICS based on the
Type of Business Activity (in Facility
Table)
Assign an SCC based on the Type of
Process (in Process Table)
Assign an SIC and NAICS based on the
Process Activity ( in Process Table)
