Odorant and odorant-equipment decommissioning should begin with the actual product, SDS, remaining quantity, contamination, container condition, waste determination, transport route, receiving facility, and federal, state, and local requirements. BPS can support field planning and documentation; the generator and qualified waste professionals determine the applicable disposal requirements.

Understanding the NFPA 704 Label

NFPA 704 communicates specified health, flammability, and instability hazards for emergency response. It does not by itself determine whether residual odorant, sorbent, rinsate, or equipment is a hazardous waste or prescribe the disposal method. Use the current SDS and a documented waste determination.

Navigating OSHA and EPA Regulations

A material is not automatically a RCRA hazardous waste because it contains an odorant or a hazardous constituent. The generator must determine whether the discarded material is a solid waste and whether it is listed or exhibits a hazardous characteristic. Container-empty status under 40 CFR 261.7 also depends on the waste and how residues were removed.

EPA Regulations under RCRA

RCRA establishes federal hazardous-waste identification and management requirements, while authorized states may administer additional or more stringent programs. Characterize residual liquid, sorbent, carbon, rinsate, piping, vessels, filters, and pumps separately as needed instead of assigning one disposal classification to the entire project.

Selecting a Licensed Contractor

Select receiving and transport providers that are authorized for the material actually being shipped. A hazardous-waste manifest is required when the shipment is regulated as hazardous waste; it should not be presented as mandatory for every odorant-equipment disposal project.

Safety Concerns and Local Regulations

Do not burn, vent, rinse, neutralize, or deodorize equipment without an approved task plan that addresses residual material, vapors, ignition sources, emissions, waste streams, worker protection, and local requirements. Product-specific SDS and emergency procedures remain controlling.


BPS can support isolation, transfer, vapor control, equipment preparation, field records, and coordination with the operator’s selected waste and transport providers. BPS does not guarantee a regulatory outcome or replace the generator’s waste determination, permits, or legal review.
