Used hazardous material containers cause substantial confusion for organizations that handle hazardous materials in California. The confusion arises out of what constitutes an empty hazardous material container and how long it can be kept.
Under federal law (40 CFR section 261.7) a container that once held hazardous materials is considered empty if it has less than 1 inch of residual material or 3% of the original product weight. In California, a used hazardous material container is still a hazardous waste unless it conforms with the empty container standards set forth in Title 22, California Code of Regulations, section 66261.7
Containers are “California empty” when:
Hazardous liquid: no liquid can pour
Solid or non-pourable hazardous material: must be completely scraped out
Aerosol cans: contents and pressure are completely dispensed
Compressed gas cylinders: inside pressure ≈ atmospheric
The important thing to remember is that if a container does not fulfill the California standard, it must be managed as hazardous waste, including the labeling, storage, retention and disposal requirements.
If a container meets the California empty standard, the container may be managed as follows:
During this period, the container can be repurposed and is then exempt from hazardous material and hazardous waste regulations, provided the repurposed container does is not used to store hazardous waste or materials. Containers that are not repurposed must be managed as follows:
California empty containers < 5 gallons may be disposed in a non-hazardous landfill. Optionally, they may be reconditioned, remanufactured, refilled or reclaimed.
California empty containers > 5 gallons must be reclaimed for scrap value, reconditioned, remanufactured or refilled. They cannot be disposed of as solid waste (in a landfill).
