Used Oil Disposal
Used oil is not considered a hazardous waste, per
the US Environmental Protection Agency and the NJ Department of Environmental
Protection. Used oil is not picked up and disposed of as part of the monthly
hazardous waste pickups, with the following exceptions:
- Vacuum pump oil from laboratories will be collected during
the monthly hazardous waste pickups, due to the possibility of contamination
with other chemicals.
Containers must be labeled "USED OIL", not "hazardous waste."
- Many cutting oils may not meet the definition of used oil.
Contact EHS at ext. 8-5294 before disposing of cutting oils in order
to determine whether they should be treated as used oil or hazardous
waste.
- PCB contaminated oil must be treated as hazardous waste. Contact
EHS if there is any suspicion of PCB contamination.
- Oil mixed into any other hazardous wastes will be treated as hazardous
waste.
With the exception of the materials listed above, EHS does not pay for disposal
of used oil and does not normally coordinate used oil disposal. EHS
continues to coordinate and bear the cost of routine hazardous waste disposal.
Used Oil Disposal
Options
There are several options for disposal of used oil that does not meet
the exception criteria listed above:
- Send to a commercial facility approved by the NJ Department of Environmental
Protection for used oil disposal. Safety Kleen will pick up used
oil on an on-call basis. The oil will be pumped from its container (must
be a 55 gallon or more drum or tank) into their storage vessel, leaving
you with your container. The costs, as of December, 2002, are as follows:
- 0-125 gallons: $60.00
- 126-275 gallons: $90.00
The Princeton University Garage will accept used oil to be placed into
their large tank, at their discretion. The cost of disposal will be shared
by all contributors.
- Used oil can be collected with the regular hazardous waste pickup
and disposed of by Triumvirate or Clean Harbors Environmental Services.
The cost of disposal will be charged back to the department. The cost
of disposal is usually $90.00 per 55 gallon drum (subject to change).
The drum will be taken with the shipment. Replacement drums may be purchased
from the disposal company for a charge of $44.00 each.
- Small amounts of waste oil (less than 2 gallons) may be taken to
a service station for recycling.
Used Oil
Collection Tips
1. Minimize the amount of water in the oil.
2. Keep all collection vessels, especially drums, sealed except when
filling the container.
3. Label containers "USED OIL", not "waste oil" or "hazardous waste".
Spills
or Releases of Oil
1. Oil spills should be cleaned up immediately. Absorbent materials (vermiculite)
and lined 5-gallon pails are available through EHS. See Chemical
Spill Clean-Up Procedures for general instructions for cleaning up
oil spills.
2. Releases to the environmental (including releases to the sewer, soil,
or impervious surfaces outdoors) must be reported immediately to Public
Safety at 911 and to Bob Ortego,
Environmental Compliance Manager, at extension 8-1841.
