At the end of this module, you will be able to:
- Differentiate between the different classifications of hazardous waste generators
- Describe the regulations for hazardous waste accumulation
- Describe the requirements for tanks and containers used for storing hazardous waste
- Explain air emission standards
- Define volatile organic compounds
The following key questions are answered in this module:
What are the hazardous waste generator categories?
Large quantity generators (LQGs), Small quantity generators (SQGs), Very small quantity generators (VSQGs)
What is a large quantity generator?
A facility that generates at least 1,000 kg (2,200 lb) of hazardous waste per month , or more than 1 kg (2.2 lb) of acutely hazardous waste per month is considered a LQG
What is a small quantity generator?
A facility that generates between 100 and 1,000 kg (220 and 2,200 lb) of hazardous waste per month is considered a SQG
What is a satellite accumulation area?
A satellite accumulation area is an area at or near the point where hazardous waste initially accumulates when generated
What is the difference between a tank and a container?
A container is any portable device in which a material is stored, transported, treated, disposed of, or otherwise handled, including large tanker trucks. A tank is a stationary vessel used to store hazardous waste.
Below is a transcript of the video sample provided for this module:
Secondary containment is also required for tanks. The containment must prevent releases to the environment due to tank failure or accidental spills such as overfilling the tank. A leak detection system is also required. Acceptable containment options are: liners, vaults, or double-walled tanks. An external liner must be made from an impervious material. The liner can be used as containment for more than one tank, but it must be capable of holding 100% of the largest tank within its boundary, plus the amount of rain from a 25-year, 24-hour storm event. Tanks can also be located in underground chambers or vaults. Most vaults are made of concrete and lined on the inside and outside to prevent waste from escaping or water from entering the vault, because concrete is porous.
