How Do I Manage My Used Oil And Used Oil Filters?
Information presented in this publication is intended
to provide a general understanding of the statutory and regulatory requirements
governing used oil and used oil filters generated by small businesses.
This information is not intended to replace, limit or expand upon the
complete statutory and regulatory requirements found in the Illinois
Environmental Protection Act and Title 35 of the Illinois Administrative
Code. These requirements can be found on line at www.ipcb.state.il.us.
What
is Used Oil?
This document is also available in Adobe Acrobat Format.
Used Oil is any petroleum-based or synthetic oil that has been contaminated
with dirt, metals, water, or other chemicals such as solvents during
use in a process. Used oil is not the same as waste oil. Waste oil includes
oils which have not been used, such as virgin oil tank bottoms or cleanup
residues from a product spill. In addition, used oil must be recycled
or burned for energy recovery. Used oils commonly generated by small
businesses include materials such as used motor oil, transmission fluid,
refrigeration oil, compressor oil, hydraulic fluid, metal working fluid,
and other lubricants.
The following materials are also regulated as used oil:
- Materials burned for energy recovery that contain or are contaminated
with used oil such as oil-soaked rags or sorbent materials.
- Oil generated from abnormal operations. Substantial leaks of oil
from pipes, pumps, and machinery such as an overflowing tank or ruptured
pipe.
- Oil removed from wastewater such as through an oil water separator.
The following materials are not regulated as used oil:
- Oil containing polychlorinated biphenyls (PCB) – This type
of oil is regulated as a special waste and is subject to certain transportation
requirements. Also, if the PCB concentration exceeds 50 parts per
million (ppm), the oil is regulated as a toxic substance. Used oil
containing 2 ppm or greater PCBs cannot be blended and may only be
marketed to a qualified PCB incinerator when sent for burning. For
more information on managing oil containing PCBs, contact the Illinois
Environmental Protection Agency (IEPA) Office of Small Business.
- Permitted wastewater discharges – This type of discharge
is regulated under the Clean Water Act and contains small amounts
of oil from small pipe, pump, or machinery leaks during normal operations.
- Waste oil and materials derived from used oil that is disposed of
in a landfill instead of burned for energy recovery – examples
of this type of material include used oil-soaked rags and sorbent
materials. In general, these materials are subject to the hazardous
waste determination requirements. If any of the wastes are determined
to be hazardous, these wastes should be handled as described in the
fact sheet titled, “How
Do I Manage My Hazardous Waste?”
- Used oil generated by farmers in amounts less than 25 gallons per
month – this material is generated by farm vehicle and machinery
use. This oil is still a waste and must be properly recycled or disposed
of.
- Material reclaimed from used oil and beneficially used - this type
of material includes rerefined lubricants.
- Used oil and fuel mixtures – when mixed by the generator and
used in facility vehicles.
- Used oil generated by household “do it yourselfers.”
This oil is still a waste and must be properly recycled or disposed.
- Material such as used animal or vegetable oils – these materials
are generated in the production of food, pharmaceutical, and cosmetic
products. These materials are a special waste but are not regulated
as used oil.
How
Should I Store My Used Oil?
CAN I RECYCLE MY USED OIL ON SITE?
Used oil can be recycled on site by reconditioning the oil to remove
contaminants so that the oil can be reused. One of the most common
ways to recycle used oil is to filter it.
There are no time limitations on storage of used oil; however, if it
is stored greater than one year and there doesn’t appear to be
any definite plan to remove the oil, it may be considered for disposal.
Used oil should only be stored in tanks and containers that are not
leaking, rusting, deteriorating, or having other defects. Used oil containers
and above ground tanks should be stored on a surface that does not allow
used oil to seep through, such as cement or asphalt. Containers, above
ground tanks, and fill pipes for underground storage tanks (UST) of
used oil should be marked with the words “Used Oil.” USTs
that store used oil should also comply with the UST general operating
requirements. For more information on UST general operating requirements,
call the Office of Small Business.
Can
I Burn My Used Oil on Site?
Used oil can be burned in oil-fired space heaters if:
- the heater burns only used oil generated on site or from a household
“do it yourselfer,”
- the heater has a maximum capacity of 0.5 million British thermal
units per hour,
- the combustion gases are vented directly to the outside air.
Can
I Mix My Used Oil with Other Non-Hazardous Waste?

TIP
It is a good practice NOT to mix your wastes, especially hazardous
waste with used oil. The management of these mixtures becomes more
complicated and some used oil recyclers will not accept the used oil
even if it is done in accordance with the used oil regulations. By
keeping your wastes separate, used oil can be managed as used oil.
Mixing used oil with other non-hazardous wastes, such as wastewater
or solvent, may make management of the mixture more complicated. Generally,
these mixtures are regulated under both the used oil regulations and
solid waste regulations. A receiving facility which accepts used oil
for recycling may not have permits to accept other solid wastes. Mixing
used oil and other waste may make disposal of the mixture more difficult
and more expensive.
Can
I Mix My Used Oil with Hazardous Waste?
IMPORTANT
Used oil with a total halogen concentration of 1,000 ppm is presumed
to be a listed hazardous waste; however, if you can show that the
used oil does not contain significant concentrations of halogenated
listed solvents, the used oil is not regulated as a listed hazardous
waste. This demonstration can be made by collecting a sample of used
oil and analyzing it for the listed halogenated solvents.
To determine the type of hazardous waste that you generate, see the
fact sheet titled “Do
I Have a Special Waste?”
Regulations for mixture of used oil and hazardous waste depends on
the hazardous waste generator status of your facility. To determine
your generator status, see the fact sheet titled “How Do I Manage
Hazardous Waste?” If you are a conditionally exempt, small-quantity
generator (producing less than 220 pounds of hazardous waste per month)
and you mix used oil with any hazardous waste generated on site, the
used oil mixture is regulated as used oil. If you are a small-quantity
generator (producing 220 to 2,200 pounds of hazardous waste per month)
or a large-quantity generator (producing more than 2,200 pounds of hazardous
waste per month), the used oil mixture is regulated as a hazardous waste
if one or more of the following applies:
- The used oil is mixed with a listed solvent or other listed waste
- The used oil is mixed with a hazardous waste that exhibits the ignitability,
corrosivity, reactivity, or toxicity characteristic and the mixture
exhibits any of these characteristics.
How
Should I Transport Used Oil?

TIP
Used oil can be transported to collection centers or processing facilities
that have both EPA and Illinois EPA identification numbers or to a
selfowned collection center.
You may transport up to 55 gallons of used oil in a self-owned vehicle
to a registered collection center and you would not have to follow the
used oil transportation rules. You may still have to be a licensed special
waste hauler. Any other type of shipment of used oil must be made by
a Illinois licensed special waste hauler with both EPA and Illinois
EPA identification numbers. Each shipment must be accompanied by a manifest.
To obtain a manifest or information about how to fill out a manifest,
contact the Office of Small Business.
How
Should I Handle Spills of Used Oil?
When used oil is spilled, the following actions should be taken:
- Steps should be taken immediately to stop the spill. If a pipe is
leaking, shut off the flow to the pipe.
- The spilled oil should be contained using the appropriate sorbent
materials such as pads or granular sorbents.
- Leaking containers, tanks, or piping should be promptly repaired
or replaced. If a leaking drum cannot be repaired, its contents should
be transferred to a new drum.
- Used oil spills should immediately be reported to the Illinois EPA
24 hour hotline at (800) 782-7860 or the National Response Center
at (800) 424-8802.
How
Should I Handle Used Oil Filters?

TIP
Hot draining should occur for a period of at least 12 hours at or
near the engine’s operating temperature and always above room
temperature (60oF). Filters that immediately drip oil when picked
up have not been properly drained.
A non-terne plated used oil filter that has been properly drained may
be recycled as scrap metal or disposed of as special waste. Terne is
an alloy of tin and lead. Special waste may be certified non-special
in accordance with the procedures in Section 22.48 of the Illinois Environmental
Protection Act. Once certified as non-special, the used oil filter may
be disposed of as general refuse. Terne-plated filters may be hazardous
waste because of their lead content. If you generate terne-plated filters,
they may be subject to testing and other hazardous waste determination
requirements. Contact the Office of Small Business for more information
on managing terne-plated filters. Draining used oil from your filters
can be performed using one of the following methods:
- Puncturing the filter anti-drain back-valve contained in most automotive
oil filters or the filter dome, and then hot draining; the anti-drain
back-valve consists of a rubber flap that creates a vacuum to prevent
oil from draining back into the engine
- Hot draining and crushing
- Dismantling and hot draining
- Any other equivalent draining method that will remove the used oil
such as pressurized air draining Used oil drained from filters can
be combined with other used oil and managed as discussed earlier in
this fact sheet.
The drained filters should be placed in covered dumpsters or containers
that prevent rain infiltration. In addition, the dumpsters or containers
should be capable of holding any residual used oil that may escape from
the filter.
For more information on how to handle used oil filters, contact the
Filter Manufacturers’ Council Regulatory Hotline at (800) 99-FILTER
or the Office of Small Business.
How
Can I Reduce the Amount of Used Oil I Generate?
IMPORTANT
After draining, a filter can contain 2 to 8 ounces of residual used
oil. Over 400 million oil filters are used in the United States every
year. Therefore, landfilling of 6.25 to 25 million gallons of used
oil in the filters could occur annually.
Reducing the amount of used oil that you generate is an important pollution
prevention (P2) measure. In addition to environmental protection, P2
can reduce operating costs and improve efficiency. The following tips
can help you reduce the amount of used oil you generate:
- Use longer lasting synthetic oils to minimize the amount of used
oil and used oil filters generated.
- Reduce the amount of virgin oil purchased by reconditioning and
then reusing used oil.
- Manage used oil safely. Do not mix it with other materials. Store
the oil in leak proof containers and tanks in secure areas away from
workers and the environment. Label all containers of used oil and
other wastes to avoid inadvertent mixing.
- Use reusable oil filters.
- Recycle used oil filters. Although properly drained used oil filters
can be disposed of as general refuse, it is recommended that these
filters be recycled to reduce the amount of used oil that is ultimately
landfilled.
