CODE ASSIGNMENT Anna Komorniczak Emission Inventory Workshop Air Resources Board March 13, 2006

Air Resources Board Emission Inventory Workshop Spring Type of Codes SCC: Source Classification Code SIC: Standard Industrial Classification NAICS: North American Industry Classification System EIC: Emission Inventory Code

Air Resources Board Emission Inventory Workshop Spring Where to Find These Codes ? Emission Inventory Procedural Manual HARP software District Resources Web Page CEIDARS Web Page in Utility Tables

Air Resources Board Emission Inventory Workshop Spring Source Classification Code (SCC) 8 Digit Code to Identify Emission Processes Created by U.S. EPA 9865 Valid SCCs Available

Air Resources Board Emission Inventory Workshop Spring Organization of SCCs Four Levels of Source Descriptions Example: First level(2-) Process Category Second level (2-02-) Major Industry Third level ( ) Product, Raw Material, Fuel Type, or Equipment Fourth level ( ) Particular Emitting Process

Air Resources Board Emission Inventory Workshop Spring Example of SCC L1 - Internal Combustion L2 - Industrial L3 - Distillate Oil/Diesel L4 - Reciprocating

Air Resources Board Emission Inventory Workshop Spring 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

Air Resources Board Emission Inventory Workshop Spring 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 Emission Inventory Workshop Spring 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) Manufacturing (Industrial) Non-manufacturing (Commercial)

Air Resources Board Emission Inventory Workshop Spring Example of SIC 1442 Construction Sand and Gravel 2023 Dry, Condensed, Evaporated Products 4911 Electric Services 5411 Grocery Stores 9999 Not Valid Code

Air Resources Board Emission Inventory Workshop Spring 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 Emission Inventory Workshop Spring Example of Facility and Process SICs Facility SIC 8062 General Medical and Surgical Hospitals Process SIC 4931 Electric and Other Services Combined SCC code (Internal Combustion - Electric Generation - Dist. Oil/Diesel - Turbine)

Air Resources Board Emission Inventory Workshop Spring 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

Air Resources Board Emission Inventory Workshop Spring NAICS vs. SIC (1) NAICS Sheep Farming Goat Farming SIC 0214 Sheep and Goats

Air Resources Board Emission Inventory Workshop Spring NAICS vs. SIC (2) NAICS General Medical and Surgical Hospitals SIC 8069 Children’s Hospital 8062 General Medical and Surgical Hospitals

Air Resources Board Emission Inventory Workshop Spring 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 Emission Inventory Workshop Spring 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 Emission Inventory Workshop Spring Example of EIC Miscellaneous Processes 618 Farming Operations (Source Category) 0262 Livestock Husbandry (Material Type) 0102 Ranch Cattle (Sub-category)

Air Resources Board Emission Inventory Workshop Spring 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

Air Resources Board Emission Inventory Workshop Spring Case Study Facility “Diamond Landfill” waste disposal facility with IC engine operations How I find SIC, NAICS and SCC?

Air Resources Board Emission Inventory Workshop Spring 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)
