How to report Hazardous Waste as Recurrent or Non-Recurrent
using the Source Codes and Origin Codes Crosswalk Table:

1) Find the waste Source Code that best describes your waste. Source codes are reported in Box A-7 on Generation and Management (GM) forms. They describe the type of process or activity (i.e., source) from which a hazardous waste was generated. Please review the Source Code groups and pick an appropriate code.

2) Use the table to pick an Origin code allowed for the Source code, or correct the Source code to pass TurboWaste.Net validation. Origin Codes in Box A-9 on the GM form show whether the waste was Recurrent or Non-Recurrent.
