Used motor oil is hazardousIf used motor oil and the contaminants it contains are disposed of inappropriately and released into the environment, they can harm humans, plants, animals, fish and shellfish.
They can be divided into seven groups depending on the type of manufacturing or industrial operation that creates them:
- Spent solvent wastes,
- Electroplating and other metal finishing wastes,
- Dioxin-bearing wastes,
- Chlorinated aliphatic hydrocarbons production,
- Wood preserving wastes,
Non-hazardous waste is any type of industrial waste which, according to regulations, cannot be added to a dumpster or sewage line. Examples of non-hazardous wastes would be sugars, lactic acid, bromides, or carbonates, just to name a few.
Oil-based paints are hazardous as they contain heavy metals and are flammable. Water based paints such as varnishes, stains, sealers etc. may contain mercury and so therefore are classed as hazardous. They can be recycled into latex-based paints.
Cradle-to-grave liability means that a generator is responsible for their hazardous waste from the time they create it until the time they dispose of it. This helps to ensure that facilities choose responsible treatment, storage and disposal methods for the hazardous wastes they generate.
Containers holding compressed gases that are hazardous wastes are considered empty when the pressure in the container approaches atmospheric pressure (§261.7(b)(2)). when triple rinsing is inappropriate, an alternate method is used (§261.7(b)(3)(ii)).
Examples of common special wastes include petroleum-contaminated soil, asbestos, stabilized grit & bar screenings, absorbent booms, and pads, liquids, pit sludge, baghouse dusts , dried paint filters, biosolids, grease/scum waste, or any other hard-to-handle material that is not considered hazardous under RCRA.
Recognizing that generators produce waste in different quantities, EPA established three categories of generators in the regulations:
- very small quantity generators,
- small quantity generators, and.
- large quantity generators.
Universal wastes are hazardous wastes that are widely produced by households and many different types of businesses. Universal wastes include televisions, computers and other electronic devices as well as batteries, fluorescent lamps, mercury thermostats, and other mercury containing equipment, among others.
Universal waste may be sent to another handler for disposal, or a company that treats, stores, or recycles waste. All Department of Transportation (DOT) regulations apply when transporting the waste off-site.
Universal waste is a category of waste materials designated as "hazardous waste", but containing materials that are very common. It is defined in 40 C.F.R. 273.9, by the United States Environmental Protection Agency but states may also have corollary regulations regarding these materials.
Within these regulations, EPA developed a streamlined management program for certain hazardous wastes, known as universal wastes. The universal waste program provides an alternative set of regulations that reduce the regulatory burden by allowing longer storage of these wastes and reduced recordkeeping.
Aerosol cans can account for nearly 40 percent of retail items that are managed as hazardous waste at large retail facilities. With this rule, EPA adds hazardous waste aerosol cans to those “universal wastes” regulated under title 40 of the Code of Federal Regulations (CFR), part 273.
Light emitting diode (LED) bulbs are less toxic and use less energy than compact fluorescent bulbs. At end of life, they are considered hazardous waste and should be disposed of properly.
LED Lamps: No Mercury, but Still Considered Universal WasteThe United States EPA has several regulations surrounding the disposal and management of potentially hazardous materials. Universal Waste is a class of materials that are widely produced and used, but have the potential to harm the environment.
The 4 Types of Universal Waste
- Universal Waste – Batteries. This includes discarded primary (non-rechargeable) and secondary (rechargeable) batteries that contain elements such as cadmium, lead, or mercury, which would render them RCRA-hazardous.
- Universal Waste – Pesticides.
- Universal Waste – Mercury Containing Equipment.
- Universal Waste – Lamps.
What is P and U Listed Waste? The P and U lists designate as hazardous waste pure and commercial grade formulations of certain unused chemicals that are being disposed.
Hazardous waste is commonly stored prior to treatment or disposal, and must be stored in containers, tanks, containment buildings, drip pads, waste piles, or surface impoundments that comply with the Resource Conservation and Recovery Act (RCRA) regulations.
Hazardous waste can be treated by chemical, thermal, biological, and physical methods. Chemical methods include ion exchange, precipitation, oxidation and reduction, and neutralization. Among thermal methods is high-temperature incineration, which not only can detoxify certain organic wastes but also can destroy them.
Hazardous wastes are classified on the basis of their biological, chemical, and physical properties. These properties generate materials that are either toxic, reactive, ignitable, corrosive, infectious, or radioactive. Toxic wastes are poisons, even in very small or trace amounts.
To have hazardous waste removed from your laboratory, do the following: Store chemical wastes in appropriate containers; plastic bottles are preferred over glass for storing hazardous waste when compatibility is not an issue. Segregate chemical waste by compatibility, and not alphabetically.
Whenever possible, halogenated and non-halogenated solvents should be placed in separate containers for waste disposal. This is because the disposal cost for halogenated materials is significantly higher than that for non-halogenated materials.
Waste containers must be labeled with:
- The words Waste Lab Waste or Hazardous Waste.
- The name or type of chemical such as Acetone or non-halogenated solvent.
- The date accumulation started and the name of the person or class generating the waste.
- Any other descriptions about the contents pertinent to the disposal facility.
Sometimes, the EPA specifies how frequently you must inspect your hazardous waste tanks, impoundments, and emissions control technology. Many of these inspection frequencies are phrased as “once each operating day”.
Select compatible containers
- Chemical compatibility: Choose a container chemically compatible with the material it will hold.
- Caps and closure: Use waste containers with leak-proof, screw-on caps so contents can't leak if a container tips over.
- Size: Choose appropriately sized containers.
- Secondary containment:
Treatment Storage and Disposal Facilities (TSDFs) provide temporary storage and final treatment or disposal for hazardous wastes. Since they manage large volumes of waste and conduct activities that may present a higher degree of risk, TSDFs are stringently regulated.
Most commercially-generated (i.e., non-DOE) mixed waste is classified as low-level mixed waste (LLMW). LLMW is waste that contains low-level radioactive waste (LLRW) and hazardous waste. LLRW is defined as any radioactive waste that is not high-level radioactive waste, spent nuclear fuel, or byproduct material.
Once you accumulate 55 gallons of waste, the container(s) must be labeled with the words "Hazardous Waste" and moved from the satellite area to your central storage area within three days. At this time, you must also record an accumulation start date on the container(s).
Used Oil: In California, waste oil and materials that contain or are contaminated with waste oil are usually regulated as hazardous wastes if they meet the definition of "Used Oil" even if they do not exhibit any of the characteristics of hazardous waste.
EPA's regulations in the Code of Federal Regulations (40 CFR) define four hazardous waste characteristic properties: ignitability, corrosivity, reactivity, or toxicity (see 40 CFR 261.21- 261.24).
Reactivity - Reactive wastes are unstable under "normal" conditions. They can cause explosions, toxic fumes, gases, or vapors when heated, compressed, or mixed with water. Examples include lithium-sulfur batteries and explosives.
The federal EPA has designated four "lists" of hazardous wastes, designated by the letters "F", "K", "P", and "U". If a material is found on one or more of these lists, it is considered a "listed hazardous waste".
The Resource Conservation and Recovery Act (RCRA) is the public law that creates the framework for the proper management of hazardous and non-hazardous solid waste. The law describes the waste management program mandated by Congress that gave EPA authority to develop the RCRA program.
