How to Select SCCHow to Select an SCCSource Classification Codes are the way the U.S. Environmental Protection Agency categorizes sources of air pollution. This spreadsheet lists all valid Source Classification Codes in eDEP. This file has been significantly expanded to include all of EPAs SCCs. (Revised May 2018)How to select an SCC for your emission unit:

1. Download and open this list of SCC Codes

2. Using the auto filter feature, in the column labeled SCC Level One click on the down arrow to display the industrial category options. Pick one that is right for your facility and unit. Click Select All once to clear the check boxes, and then check the one you selected. This will filter out all of the other types and display only the one you want.

3. Click on the down arrow in the column SCC Level Two to refine search for the emission unit. Pick one as you did for Level One.

4. Follow this procedure using the auto filter feature in the other two columns to retrieve the appropriate SCC.

5. If you cannot find a good match this way, then you could start by selecting Level One and then a fuel in Level Four, and then selecting the closest possible in Level Two and Level Three. Getting the fuel correct is most important for combustion sources. To undo your filtering and start over, click on the in the columns you have already filtered and check Select All this will clear all of the filters.NOTE: this may work somewhat differently in older versions of Excel or other spreadsheets programs.NOTE: Each SCC has a units field assigned this will be the units in which you will need to report your throughput amounts.NOTE: The column labeled Category indicates whether or not auto calculation of emissions is available for that SCC on the AP1 form. If the Category = COMBUSTION, then auto calculation is available.If you are not successful in finding an appropriate SCC and would like help, contact MassDEP via email at: air.quality@state.ma.us for assistance.The source for SCC is the U.S. EPA EIS system at: [https://ofmpub.epa.gov/sccsearch/]You can download SCC list from EPA's WebFIRE Data in Bulk. WebFIRE is EPAs online emissions factor repository, retrieval, and development tool. The complete WebFIRE data set is available as comma-separated values (CSV) file format. This is a very simple data file format that is supported by almost all spreadsheet software such as Microsoft Excel, as well as Microsoft Access.

Valid SCCsValid Source Classification Codes (SCC) in eDEPMay 2018 rev --minor corrections and updates from EPASee tab How to Select SCC for instructions on picking an SCC for your emission unit.This list contains all of the SCC that will validate in the on-line Source Registration forms. If you cannot find the appropriate SCC for your operation, or you have one the needs to be added, e-mail air.quality@state.ma.usCategory = COMBUSTION indicates that SCC will autocalculate emissions on AP1 or AP2 formSCC which EPA has deemed invalid are listed in 2nd sheet along with new valid codes if available from EPA.CommentSCC CodeUnitsSCC Level OneSCC Level TwoSCC Level ThreeSCC Level FourDEP SCC DescriptionCATEGORYFuelEI Sectorlast inventory yearmap tousage notes10100101TONSExternal Combustion BoilersElectric GenerationAnthracite Coal, PulverizedBoilerExternal Combustion Boilers -
