Source Classification Code (SCC) 8 Digit Code to Identify Emission

Processes Created by U.S. EPA 9865 Valid SCCs Available

Air Resources Board


5

Organization of SCCs

Four Levels of Source Descriptions Example: 2-02-001-02 First level(2-) Process Category Second level (2-02-) Major Industry Third level (2-02-001-) Product, Raw

Material, Fuel Type, or Equipment Fourth level (2-02-001-02)

Particular Emitting Process

6

Example of SCC

2-02-001-02 L1 - Internal Combustion L2 - Industrial L3 - Distillate Oil/Diesel L4 - Reciprocating

Air Resources Board


7

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

Standard Industrial Classification (SIC) 4 Digit Code to Identify Business

Activity Published by U.S. Office of

Management and Budget (OMB) 1700 valid SICs Available

Air Resources Board


9

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)

0111- 3999 Manufacturing (Industrial) 4011- 9721 Non-manufacturing

(Commercial)

Example of SIC 1442 Construction Sand and

Gravel 2023 Dry, Condensed, Evaporated

Products 4911 Electric Services 5411 Grocery Stores 9999 Not Valid Code

11

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

Air Resources Board


12

Example of Facility and Process SICs Facility SIC 8062 General Medical

and Surgical Hospitals Process SIC 4931 Electric and

Other Services Combined SCC code 2-01-002-01 (Internal

Combustion - Electric Generation - Dist. Oil/Diesel - Turbine)

Air Resources Board

North American Industry Classification System (NAICS) NAICS replaces the 1987 SIC 6 Digit Code for Classifying

Business Establishments Created and Maintained by U.S.

OMB Reflects the Structure of Economy

Including the Service Sector and New Technologies

Emission Inventory Code (EIC) 14 Digit Code to Classify and Report

Emission Data by Specific Source Categories

Created and Maintained by ARB Identify Each Area Source Category Provide Automatic Reconciliation for

Area and Point Sources

Air Resources Board


17

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

Air Resources Board


18

Example of EIC

620-618-0262-0102

620 Miscellaneous Processes

618 Farming Operations (Source Category)

0262 Livestock Husbandry (Material Type)

0102 Ranch Cattle (Sub-category)

Air Resources Board


19

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

Case Study Facility “Diamond Landfill” waste

disposal facility with IC engine operations

How I find SIC, NAICS and SCC?

Air Resources Board


21

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)
