Maintenance Related Waste: Best Management Practices


Both the State and Federal Environmental Agencies have regulations concerning the management of maintenance – related waste materials.  The regulations are enforced by the Environmental Protection Agency (EPA) and by the Florida Department of Environmental Protection (DEP).  The intent of these regulations is to establish a comprehensive program for the proper management and disposal of maintenance – related wastes.  This document is based on those regulations and should serve as a guideline for all maintenance and repair shops located at the University of Florida.

The purpose of this document is to assist shops with regulatory compliance.  Every shop on campus is subject to unannounced inspections by both the Federal Environmental Protection Agency (EPA) and the Florida Department of Environmental Protection (DEP).  Lack of compliance can result in citations and fines.  The regulatory requirements covered in this document include:

  • Hazardous Waste Determination
  • Proper Labelling of Waste
  • Proper Accumulation and Disposal of the Waste

No Hazardous Waste, Universal Waste, or used oil may be delberately Discharged to the Sanitary sewer, to the ground or to the University storm water system.

Waste Determination

A waste is a material or chemical that has no intended use or reuse.  Wastes also include materials or chemicals from a spill clean-up.   A Hazardous Waste is defined by the EPA as either a Listed waste or a Characteristic waste.  Mixtures of non-hazardous materials with hazardous wastes may be hazardous wastes also.

Hazardous Waste

Listed Hazardous Waste

The EPA has published four lists identifying hazardous wastes:  

  • F-Listed – Wastes from non-specific sources such as waste waters and spent solvent mixtures
    Examples: Acetone, Xylene, Trichloroethylene
  • K-Listed – Wastes from specific industrial sources
    Example: Wood Preserving, chemical manufacturing
  • U-Listed – toxic wastes
    Examples: Toluene, Formaldehyde, Acetone              
  • P-Listed – Acutely toxic wastes
    Examples: Nicotine, Epinephrine, Endosulfan, Aldicarb

Refer to the Toxicity Characteristic List to determine if your waste is listed.

Characteristic Hazardous Waste

A waste is hazardous if it exhibits any one of the following four characteristics:


  • Flammable Liquids – FlashpointExamples: Alcohols, Benzene, Toluene, Xylene, Acetonitrile
  • Oxidizers
    Examples: Solid pool/fountain chlorine (Sodium Hypochlorite), Nitrate Fertilizers, Potassium Permanganate


  • Acids
    Examples: Muriatic Acid (Hydrochloric Acid), Battery Acid (Sulfuric Acid), Rust Inhibitors (Phosphoric Acid)
  • Bases (Alkalines)
    Examples: Drain Cleaners (Sodium Hydroxide), Floor wax strippers (Monoethanolamine), Alkaline Coil Cleaners


Materials which can react violently with water, create toxic and /or flammable gases when mixed with water, ignite or react upon exposure to air, or are capable of detonation at standard temperature and pressure.

  • Sulfides and Cyanides


A selected group of eight (8) heavy metals, ten (10) pesticides, and twenty-two (22) organic chemicals are classified as hazardous due to their toxicity characteristic. Any detectable amount of these chemicals must be identified on a hazardous waste label.  Refer to Toxicity Characteristic List for complete list.

A material becomes a waste by making a Hazardous Waste determination. This determination must be made by laboratory testing or by using “generator knowledge”.   Information to support your decision may be found on the product label or the Material Safety Data Sheet (MSDS).  Mixtures, residues, spent towels, rags, absorbents or other debris contaminated by a hazardous chemical (either by process or due to a spill) should be considered to be a potential hazardous waste.  Contact EH&S for assistance in making a hazardous waste determination.

Universal Wastes

A Universal Waste is a Hazardous Waste subject to the special requirements of 40 CFR part 273.  

Universal Wastes include

  • Regulated Lamps
  • Regulated Batteries
  • Waste Mercury Containing Thermometers and Devices

Used Oil

Used Oil means any oil that is refined from crude oil, or any synthetic oil, that has been used and as a result of such use is contaminated by physical or chemical impurities. Used oil is not vegetable oil or animal derived oils.

Accumulation Requirements

Satellite Accumulation Area:  An accumulation point for waste near the point of generation and under the immediate control of the generator. All UF shops must accumulate waste in satellite areas and under those guidelines as described below.

Hazardous Waste

Hazardous Waste must be accumulated safely at or near the point of generation (designated location in the work shop) under the control of the generator (shop supervisor)

Do not accumulate more than 55 gallons of waste at any one time.

Keep all containers closed and labeled.

Provide secondary containment for containers.

Keep containment area clean and protected from the weather.

Do not allow any accumulation of water or liquid on the top of the container.

All waste containers must have a label identifying the contents.

No un-approved waste in sink or trash.

Do not overfill containers; leave at least 1 inch of headspace.

Keep liquid and solid waste streams separate.

Keep a spill kit within easy access for all shop personnel.

Post the EHS Satellite Accumulation Area Form.

Universal Waste

Accumulation of universal waste – all universal waste must be labeled, dated and may be accumulated for no more than one year from the time it becomes at waste.

Used Oil  

Accumulation of Used Oil

Do not combine hazardous waste or suspected hazardous wastes with used oil.

Generators must store used oil in appropriate containers such as DOT approved drums or tanks that are dedicated solely for the storage of used oil.

Portable container size must be less than or equal to 30 gallons.

If tanks or containers are not double-walled, they shall be stored on an oil-impermeable surface such as sealed concrete or asphalt, and must have secondary containment which has the capacity to hold 110% of the volume of the largest tank or container within the containment area.  (62-710.401 F.A.C. Specific Authority 403.061, 403.704 FS. Law Implemented 403.751 FS. History –New 6-9-05.)

Storage containers and secondary containment must be protected from weather.

Secondary containment must be kept free of spills and debris.

Any leak or spill must be contained and cleaned up immediately and the container repaired or replaced.

Containers must be kept Closed at all times.

Each container must be labeled with the words “Used Oil” and all containers must be maintained in good condition.

Labeling & Chemical Waste Pick-Up Requests


All containers must have a label identifying the contents.

Waste containers must have the appropriate label identifying the type of waste and the contents (i.e. Hazardous Waste should have a Yellow Hazardous Waste label, batteries should have a “Universal Waste – Batteries” label, etc.).  

EH&S provides “Hazardous Waste” labels, “Used Oil” labels, as well as “Universal Waste” labels for batteries, fluorescent lamps and mercury containing devices.

Universal Waste labels must include the date that accumulation began.

Labels should include all constituents in the waste mixture as well as an approximate percentage of the total for that item.  Labels should also include the Bldg and room number of the shop generating the waste and the name of the shop supervisor.

Labels are available free of charge by calling the EH&S at (352) 392-8400 and providing a P.O. Box number or specific delivery location.

Pick-Up Requests

Pick-up request should be made in advance of reaching the satellite area limit of 55 gal.  If you anticipate reaching or going over the limit, contact EH&S at (352) 392-8400.

You can submit your pickup request online by filling Chemical Waste Pickup request form

Specific Waste Streams 

The following is a list of the more common wastes and processes generated by maintenance operations:   Universal Wastes are noted by the letters “UW”.

Used Oil

The term “Used Oil” is a broad category and includes motor oil, vacuum pump oil, synthetic oils, transmission and brake fluids, lubricating greases, etc.

Used oil does not include products derived from vegetable or animal fat.

Used oil is prohibited from going to a landfill or being discharged to the environment.

EH&S must perform a hazardous waste determination on each oil waste stream to find out if it should be classified as hazardous.  If the used oil stream is determined to be hazardous, then the oil must be handled as a hazardous waste and EH&S must dispose of it.  The main reason for an oil stream to be classified as hazardous is through its contact with solvents (such as brake cleaners and paints) or heavy metals. 

Transformer oil (for PCBs) and refrigerant oil (for CFCs) must be tested by EH&S for contamination.  Keep these oil waste streams separate-do not add to a larger used oil container or tank.

If the used oil is determined not to be hazardous, it may be sent to a recycling center or to EH&S for disposal.

Shipments of Used Oil

Generators must ensure that their used oil is transported only by transporters who have a current Used Oil Transporter Certificate of Approval issued by the Department of Environmental Protection.

In order for a transporter to receive the Certificate of Approval, they must have a DEP/EPA identification number and a used oil training program, and will have demonstrated minimal insurance coverage.

Contact EH&S at (352) 392-8400 for the names of approved transporters.

Records must be kept for all used oil disposal.

“Oily wastes” are also covered under these regulations.  Oily wastes are defined as “those materials, which are mixed with used oil and have become separated from that used oil.”   This includes oil that has been mixed with “kitty litter,” absorbent clay and organic absorbent material.  These materials (with the exception of rags and paper towels) may be land filled provided that:

The amount generated is a small amount.

It is the result of minor leaks or spills from a normal process operation.

All free-flowing oil has been removed to the practical extent possible.

Large quantities of oily wastes, generated as a result of a major spill or in lieu of proper maintenance of the processing equipment, must have a hazardous waste determination performed prior to disposal.  Contact EH&S at (352) 392-8400 to have a hazardous waste determination performed.  EH&S strongly recommends that this type of waste be minimized through good housekeeping practices.

Oily rags must be picked up by EH&S or sent to a rag cleaning service.

Used Oil-Filters

Commercially generated used oil-filters are banned from landfill disposal.  A registered used oil-filter processor must process the filters.

The storage containers must be protected from weather, have a lid and stored on an oil impermeable surface.

Records must be kept for all used oil filter disposal

Used Oil-filters must be stored in above ground containers, which are in good condition and are clearly labeled “Used Oil-Filters”.

Shop Towels

Clean-up towels commonly referred to as “Shop Towels” are a re-usable product provided by a company which delivers, collects, launders and returns them.  By virtue of this arrangement, the towels are never disposed of by the University of Florida and therefore not “waste”.  No hazardous waste determination is required.

Shop Towels should be collected in a fire-safe steel safety can.

Shop Towels should not be soaked with liquid and there should be no standing liquid in the bottom of the Shop Towel container.

Absolutely nothing other than used shop towels should be collected in a Shop Towel container.

Contaminated paper towels and other disposable towels, when contaminated with Hazardous Materials are considered Hazardous Waste. 

Shop Towel collection container should be labeled “Shop Towels.”

If a Shop Towels service towel is disposed of, it becomes a waste and is subject to hazardous waste determination.


New or Unused anti-freeze is not considered a hazardous waste when disposed.

Used antifreeze may contain regulated heavy metals such as lead, chromium and cadmium from normal use.  It may also contain contamination from brake cleaners and other solvents through incidental contact. 

A hazardous waste determination must be made to insure proper disposal.  Contact EHS for assistance in making the determination. 

Used anti-freeze should be stored in an area with appropriate secondary containment and with protection from the weather.   Secondary containment must be kept free of spills and debris.

Antifreeze containers must stay closed.

Label containers with the words “Used Anti-freeze”. 

Proper recycling of used anti-freeze is encouraged.  There are waste antifreeze service companies that will service and recycle your antifreeze.  Copies of all notices, certifications, waste analysis data and other documentation must be retained for five years from the date that the waste was sent to a recycling facility or to EH&S’s Waste Management Facility.  Contact EH&S at (352) 392-8400 to get a list of vendors approved for recycling antifreeze.

Universal Wastes

Batteries (UW)

Many batteries contain regulated heavy metals and a strong acid or alkaline solution, which would qualify them as hazardous waste when they are disposed.    Used batteries and a select few other materials that can be recycled instead of becoming hazardous waste are known as Universal Wastes.   Universal Waste batteries may not be disposed of in the regular trash.

Only Alkaline batteries can be disposed of in the trash.

Large Storage Batteries (Auto, Marine, etc.) must be taken to Hazardous Waste Management Facility (Bldg 831) in the Surge Area.  Deliveries can be made every Monday, Wednesday and Friday between 8 and 9 AM.     

All other batteries such as Ni-Cds, Lithium ions etcetera which contain hazardous metals such as mercury, lead, silver, lithium and cadmium must  be handled by EH&S .

Containers of used batteries to be recycled must be labeled “Universal Waste- Batteries”, “Waste Batteries” or “Used Batteries”. 

Containers must be marked with the date accumulation began. 

Mercury Containing Devices (UW)

Mechanisms or devices which contain elemental mercury (liquid) as an integral part of the device such as: thermostats, thermometers, pressure switches, etc. are considered Universal Waste if recycled.   Mercury containing devices must not be disposed of in the regular trash.

Mercury Containing Devices must be accumulated in a closed, labeled container.

Containers of mercury containing devices or mercury thermostats must be labeled ”Universal Waste-Mercury Containing Devices” or “Universal Waste- Mercury Containing Thermostats”. 

Containers must be marked with the date accumulation began.

Light Bulbs (UW)

Fluorescent, Mercury Vapor, High Pressure Sodium and High Intensity Discharge (HID) bulbs contain mercury and would qualify as a hazardous waste unless they are recycled.  When sent for recycling they are considered Universal Waste.    Universal Waste lamps may not be disposed of in the regular trash.

Used Lamps must be accumulated in a closed labeled container.  

Broken lamps should be collected in a bag lined box or other sealed container.

Used lamps must be delivered to EH&S’s Waste Management Facility, Building 831 on Monday, Wednesday and Friday between 8 and 9 AM.  

Incandescent lamps may be disposed of in the regular trash.  If you have a question, contact EH&S before disposing of any used lamp.

Spent Lamps should be labeled (“Universal Waste – Lamps”).

Containers must be marked with the date accumulation began.

Lamp Ballasts

All lamp ballasts including PCB and “Non-PCB” are collected for recycling or processing.   Lamp ballasts removed from lighting fixtures may include an insulating material which contains PCBs (Poly Chlorinated Biphenyls) or DEHP (Di (2-ethylhexyl) phthalate).   

Ballasts contaminated with these chemicals are prohibited from landfills and must be collected for recycling.    

Emergency lighting ballasts contain a circuit board and Ni-Cd rechargeable batteries (which must be recycled).   

All ballasts can be delivered to Bldg. 831 every Monday, Wednesday and Friday between 8 and 9 AM. 

Smoke Detectors

 Some smoke detectors contain radioactive material.  A label on the back or side of the detector will alert you to the presence of a radiation source.  It is necessary to dispose of these detectors at a licensed radioactive waste disposal facility through EH&S.  

The detectors must be intact for disposal.  Some smoke detectors containing radioactive materials may be exempt from these disposal requirements. 

Contact EH&S at (352) 392-8400 to determine if your smoke detectors are exempt or regulated prior to disposing them.

It is recommended that detectors, which do not contain radioactive materials be used, if they are appropriate for your application, to avoid disposal costs, which may exceed the purchase price of the detector.

Paints, Paint thinners and Solvents 

Latex Based Paints

Latex Based Paints are not hazardous waste.  However liquid latex paint may not be disposed of in solid waste containers or in storm drains.  Old latex based paints may be consolidated into larger containers for disposal cost savings.  Small quantities remaining in cans may be air dried before disposal.

If the paint in the can is completely dry, it may be disposed of in the trash.

Dried rags and paintbrushes that are contaminated with latex-based paints only may be placed in the trash.

The rinsate water from the cleaning of rags and brushes contaminated with latex paints must be disposed of in a drain that goes directly to the wastewater treatment plant.   No rinsate may go to the storm drains.

Solvent Based Paints

Solvent Based (“oil based”) Paints, enamels, varnishes, sealants, etc. meet the definition of hazardous waste and unused portions must be disposed of by EH&S.

Paint cans that once contained non-latex paints must meet the definition of empty before they can be placed in the trash.  This is achieved by scraping the container to ensure that all pourable materials have been removed.  The pourable material must be collected for disposal by EH&S.

Waste mixtures of solvent based paint and paint thinners/solvent must be collected in a closed, labeled container.

Each container of solvent based paint/paint thinner waste must be closed after additions and the funnels should be cleaned out regularly.  No air drying of solvent based paint or paint waste is allowed.   

Waste containers must be stored with secondary containment and protected from the weather.  Secondary containment must be kept clear of spills and debris.

Containers and drums can be obtained by calling EH&S at (352) 392-8400.

Solvent Based Paints should be labeled as a Hazardous Waste.

Solvent Waste

Solvent waste (including thinners, cleaners, degreasers, fuel additives, adhesive removers, etc.) qualifies as Hazardous Waste and cannot be disposed of in the trash or sink.  

Once these solvents are no longer usable, the liquid must be placed in a suitable closed container (preferably the original container) and be labeled as a Hazardous Waste.

Brushes and Rags

Brushes and rags that have been contaminated with hazardous waste (non-latex paints, cleaners, thinners, strippers, etc.) and/or waste solvents cannot be placed in the trash.

Paper towels, wipes, rags or absorbents that have been contaminated with paint/paint thinner waste or solvent waste must be collected as hazardous waste in a steel safety container.

Call EH&S at (352) 392-8400 for information on special containers.

Excess liquid that pools from contaminated rags must be separated and collected with liquid solvent waste.

Each container of hazardous waste must be labeled and must stay closed.

Aerosol Cans

Many of the products used in maintenance work including cleaners degreasers, adhesive and adhesive removers, paints, sealants and lubricants come in the form of an aerosol spray can.  Nearly all of these aerosol products contain a flammable or poison solvent as the product base or the propellant.    Waste poisonous or flammable solvent is hazardous waste.  Any aerosol can with poisonous or flammable material left inside is hazardous waste.  

Only empty aerosol cans are to be placed in the trash.

Aerosol cans that are not empty must be accumulated in a container or drum and picked up by EH&S.

Remove spray tip to avoid discharge in the drum.

The aerosol waste container or drum must be labeled as Hazardous Waste.

Acid/Alkaline Wastes

A method for cleaning AC coils involves spraying the coil with a strong acid or base.  This should be followed with spraying the coil with a neutralizing solution prior to rinsing the coil. The neutralized solution must be directed into a drain which runs to the sanitary sewer.  Discharges to the storm drain are not permitted.  Contact EHS for variations to this protocol.  Strong acid are also used for surface preparation during soldering.  If a lead-base solder is used the acid solution may become contaminated with the metal and it will in turn contaminate the towel or rag used to apply it.

Common acids include; muriatic acid (Hydrochloric acid), sulfuric acid, phosphoric acid and nitric acid.

Do not accumulate acids, bases and solvents together.  They should each have their own separate containers and should be stored so that they cannot mix in the case of a leak.

Spent acid waste should be collected as Hazardous waste in a tight sealing plastic container.  If used with metals, they should be included on label.

Towels or rags used to apply acids or bases should be collected separately from the spent acid.

Spent Acid wastes should be labeled as Hazardous Waste.

Building Services Waste

The housekeeping, janitorial and floor maintenance work done by building services requires a wide variety of chemical products.   Use of products that are known to be hazardous (Label, MSDS) will likely generate a hazardous waste.

Attempt to find/use non-hazardous products whenever possible.

Hazardous Waste determination must be made to insure proper management.

Check Product Label, MSDS for information or contact EH&S for guidance on Hazardous Waste Determination.

If the waste is found to be hazardous, accumulate as Hazardous Waste for EH&S pick-up.

No building service wastes should ever be discharged to the environment (parking lot, grass, storm drain, etc.).

Use all products as directed on label, unusable products should be disposed of by EH&S.

Non-hazardous cleaning product waste liquids may be sent to the sanitary sewer.

Building service waste determined to be hazardous must be labeled as Hazardous Waste.

Parts Washing Waste

Recycling parts washers – Recycling parts washers use a variety of solvents to clean small parts.   The fluid is typically recycled internally and re-used until it is no longer viable.  Due to contamination with regulated metals and solvents, all waste from parts washers should be considered hazardous unless testing confirms otherwise.

The waste from these can be broken into three categories depending on the design: the fluid, sludge, and the filter (if equipped).

Parts washer fluid and sludge should be collected separately from filters.

Parts washer wastes should be collected in an appropriate container and stored in an area with appropriate secondary containment protected from the weather. 

Parts washer wastes should be labeled with a Hazardous Waste label.


Vehicle Washing

Vehicle Washing must be conducted at a wash-down station equipped with a functioning and maintained oil water separator.  Accumulated sludge from oil water separators may contain heavy metals or solvent contamination. A hazardous waste determination must be completed prior to sludge disposal. 

Effluent from the separator must be directed to the Wastewater Treatment Plant.  

Vehicle washing wastewater must not be sent to soil or to the storm water system.

To limit contamination, solvent based cleaners are not permitted.

Only soap and hot water or steam washing is permitted. 

Small Equipment and Parts Degreasing

Small equipment may require the use of a solvent or degreasing agent in order to prevent damage or corrosion to the equipment due to using water based cleaners.  Degreasing of small equipment using solvents or degreasing solutions should be done in such a way that all waste and solvent used are contained or captured. 

Waste generated during degreasing of small equipment must be collected for characterization and proper disposal (This includes towels/rags contaminated with parts washing fluid.

Shop Towels that are sent to a Shop Towel service may be use.

No discharge to the storm water system is permitted.  

Small equipment degreasing wastes should be collected in an appropriate container with a Hazardous Waste label.

Transfers of fuel or oil

To prevent spills into the environment, transfers of fuel or oil between vehicles, tanks, transformers, etc must be done with equipment or a structure in place to provide spill containment.   Spill containment may be temporary but must be fabricated in a manner that prevents any spillage from reaching the environment. 

During the transfer process an attendant who can terminate the transfer in event of spills must be present. 

Spill control equipment, clean up materials must be present.

In the event of a spill that reaches soil or water contact EH&S Waste Management immediately at (352) 392-8400 during normal operating hours or after hours contact University Police Department at (352) 392-1111.

Spill waste (including liquid and solid absorbent waste) must be collected.  A hazardous waste determination based on the make-up of the spilled material should be made.

If hazardous, spill waste should be labeled with a hazardous waste label and collected by EH&S.

Processes not listed in this guide

For processes or waste not listed or described in this guide contact EH&S for assistance in making a Hazardous Waste determination and/or for proper waste management. 

Safety Precautions

Do not mix incompatibles (ex. Acids/bases, flammables/oxidizers, reactives)

Do not bring cleaning materials from home.

Wear personal protective equipment.

Spill Response

Minor Spill

If the spill is isolated and the material can safely be handled by shop personnel, absorb and collect the spill waste.  Place the spill waste in an appropriate container for EH&S waste pick up.

Major Spill

In the event of a spill of a dangerous or hazardous chemical within the shop, contact EH&S (352) 392-8400.  If the spill represents a threat to personnel safety, evacuate the area immediately and prevent re-entry until the danger has been eliminated.  Be prepared to provide information such as: name of material spilled; approximate quantity; specific location of spilled material; contact information (i.e. name and telephone number where you can be reached)  

Spill to the environment

In the event of a spill that reaches soil or water contact EH&S Waste Management immediately at (352) 392-8400 during normal operating hours or after hours contact University Police Department at (352) 392-1111.

Waste Minimization

Waste minimization is any action that reduces the amount and/or toxicity of wastes that must be shipped off-site for disposal.  There are three methods of waste minimization.

Source Reduction

The most desirable method of waste minimization is source reduction.  This is any activity that reduces or eliminates the generation of waste at the source.  This can be accomplished by good materials management, substitution of less hazardous materials and good shop operating procedures.  The following are some examples: 

Implement a waste minimization policy and train all employees.

Make a commitment to reducing waste in all areas of the shop.

Evaluate the wastes being generated and identify areas where changes can be made.

Encourage employee participation through education, training and incentives.

Evaluate procedures to see if a less hazardous or non-hazardous materials could be substituted.

Centralize purchasing of material through one person in the department.

Minimize inventory and use a first-in, first-out system.

Keep MSDS’s for chemicals on file.

Inventory materials and identify their location at least once a year.

Update inventory when materials are purchased or used up.

Purchase chemicals in the smallest quantities needed.

Label all containers to prevent the generation of unknowns.

Avoid the use of materials containing arsenic, barium, cadmium, chromium, lead, mercury, selenium, and silver.

Substitute red liquid (spirit-filled), digital, or thermocouple thermometers for mercury thermometers when it is feasible.

Consider using detergent and hot water for cleaning parts instead of solvents.

Use latex-based paints because typically they are non-hazardous.

Find a vendor that will recycle used antifreeze.  Some vendors will recycle the antifreeze on site so the antifreeze never leaves the site.

Use multi-purpose solvents to reduce the types of hazardous waste that needs to be managed

Avoid offers of free materials and samples unless it is certain that they will be used and a clear savings will be achieved.  Disposal of unwanted chemical material can easily become more costly than perceived savings.


After source reduction, the next method to consider is recycling.  When a waste material is used for another purpose, treated and reused in the same process, or reclaimed for another process, this is called recycling.  The following are examples:

When solvent is used for cleaning purposes, re-use contaminated solvent for initial cleaning and fresh solvent for final cleaning.

Purchase compressed gas cylinders (including lecture bottles) only from manufacturers who will accept empty cylinders for return.

Return excess pesticides to the distributor.

Do not contaminate used oil with solvents because this prevents the oil from being recycled.

Recycle solvents.


Materials which cannot be reduced, recycled or eliminated outright, may possibly be treated in lieu of hazardous waste disposal.  Treatment must be conducted in accordance with federal and state regulations at an EPA permitted facility.  Only simple neutralization is permitted at Satellite Accumulation Areas. 

Toxicity Characteristics

Wastes containing even trace amounts of the following chemicals are considered Hazardous Waste and must be managed according to federal regulations
