Agency adds new temporary hazardous waste storage, transfer codes
The Environmental Protection Agency (EPA) has added new Management Method Codes to describe how hazardous waste will be managed after temporary storage and transfer. The codes are used for Biennial Hazardous Waste Reports and e-Manifests required by the Resource Conservation and Recovery Act (RCRA).
What are the changes?
The new “S Codes” are effective as of January 1, 2025. The S Codes will ultimately replace code H141 for Storage and Transfer for the RCRA Biennial Reports and e-Manifests. EPA will remove Code H141 from the Biennial Report and e-Manifest on January 1, 2027.
Hazardous waste handlers will use the S Codes on the Biennial Report Waste Generation and Management (GM) forms. The S Codes indicate that (a) hazardous waste was received to be stored or transferred and (b) the hazardous waste will later be managed by a final receiving facility using a specific method.
What are the new codes?
The new Management Method Codes include the following:
S Code | Description |
S010 | Stored and transferred for metals recovery |
S011 | Stored and transferred for mercury recovery |
S015 | Stored and transferred for deployment/deactivation of airbag waste |
S020 | Stored and transferred for solvents recovery |
S039 | Stored and transferred for other recovery or reclamation for reuse |
S040 | Stored and transferred for incineration |
S041 | Stored and transferred for open burning/open detonation |
S042 | Stored and transferred for thermal desorption |
S070 | Stored and transferred for chemical treatment |
S081 | Stored and transferred for biological treatment |
S090 | Stored and transferred for polymerization |
S100 | Stored and transferred for physical treatment only |
S110 | Stored and transferred for stabilization |
S113 | Stored and transferred for stabilization to remove HW characteristics or to achieve delisting levels |
S120 | Stored and transferred for comb. of chemical, biological, and/or physical TRT |
S121 | Stored and transferred for neutralization only |
S122 | Stored and transferred for evaporation |
S129 | Stored and transferred for other treatment |
S130 | Stored and transferred for surface impoundment that will be closed as landfill |
S131 | Stored and transferred for land treatment or application |
S132 | Stored and transferred for landfill (with prior treatment and/or stabilization) |
S134 | Stored and transferred for deepwell or underground injection |
When do the new codes apply?
Handlers may use the new S Codes on the 2025 Biennial Report GM form, on the 2026 Annual Report in some states, and for e-Manifests. While handlers may continue using code H141, EPA recommends shifting to S Codes before January 1, 2027, when code H141 will be removed.
Key to remember: EPA’s new S Codes for Biennial Reports and e-Manifests indicate how the final receiving facility will manage temporarily stored and transferred hazardous waste.
