Used oil is defined as petroleum-derived and synthetic oils which have been spilled into the environment or used for (1) Lubrication/cutting oil; (2) Heat transfer; (3) Hydraulic power; or (4) Insulation in dielectric transformers. The definition of used oil excludes used petroleum-derived or synthetic oils which have been used as solvents. (Note: Used ethylene glycol is not regulated as used oil under 10 CSR 25.)
The Missouri Department of Natural Resources has adopted and amended federal regulations for used oil that provide strong safeguards against potential types of mishandling that may occur. This technical bulletin describes the management standards for used oil transporters and transfer facilities under 10 CSR 25-11.279, which became effective Aug. 28, 1994. The standards are designed to encourage recycling while protecting human health and the environment.
A used oil transporter hauls used oil to another site for recycling or disposal. Transfer facilities that are holding areas, such as loading docks and parking and storage areas, must comply with the transporter requirements when used oil shipments are held for more than 24 hours but no more than 35 days en-route to their final destination.
Used oil transporter standards do not apply to on-site transportation, generators who self-transport 55 gallons or less of used oil to a used oil collection center or to a used oil aggregation point, and householders and exempt farmers who transport their own used oil to a regulated used oil generator, collection center, aggregation point, processor, re-refiner or burner. All other used oil must be shipped with a used oil transporter having a Missouri Hazardous Waste Transporter License and a U.S. Environmental Protection Agency (EPA) identification number.
Used oil destined for recycling is no longer considered a state hazardous waste and does not require a manifest for shipping. Instead, the Transporter’s Used Oil Shipment Record found at the end of 1 CSR 25-11.279 is used.
Used oil that is not intended for recycling or that cannot be recycled retains the D098 designation. Low concentration polychlorinated biphenyl used oil that is destined for disposal retains the D096 designation. Shipments of D098 or D096 waste must be accompanied by a hazardous waste manifest.
Transporters must meet the following standards:
- Obtain a Missouri Hazardous Waste Transporter License
- Obtain an EPA generator identification number from the department
- Determine total halogen content of used oil being transported or stored at a transfer facility and maintain records of determination
- Keep tanks and containers that are exposed to rain closed except when adding or removing used oil
- Process and store used oil in areas with oil-impervious floors
- Provide secondary containment equal to or greater than 10% of the containerized waste volume or the volume of the largest container, whichever is greater
- Clean up used-oil spills or leaks to the environment and notify proper authorities
- Comply with applicable U.S. Department of Transportation requirements
- Deliver used oil to a used oil transporter, a processor or re-refiner, an off-specification used oil burner, or an on-specification used oil burner
- Maintain an inventory log to assure that storage at transfer facilities is limited to 35 days
- Track incoming and out-going used oil shipments, using the Transporter’s Used Oil Shipment Record, a form available from the department
- Properly manage residues from used oil storage or transport
- Remove and properly dispose of hazardous waste and hazardous residues at closure of the storage area
- Report annually to the Waste Management Program Director, on the Transporter's Used Oil Annual Report MO 780-1555
