Conditionally Exempt Small Quantity Generators (CESQG) |
Businesses that generate a small volume of waste are known as Conditionally Exempt Small Quantity Generators (CESQG). CESQG waste is exempt from the disposal and processing requirements for hazardous waste generated in larger quantities if the waste generator meets certain conditions. The Texas Commission on Environmental Quality (TCEQ) has information on their web-site at www.tceq.state.tx.us regarding CESQG waste.
Acutely Hazardous Waste (Federal Regulations)
Acutely hazardous wastes are listed as "P" wastes in the federal system. The main difference between P listed wastes and other federally regulated hazardous waste is the criteria used to identify acutely hazardous chemicals. The criteria:
Extremely Hazardous Waste (TECQ Regulated)
Extremely or acutely hazardous wastes are a special category in the waste regulations. Federal regulations oversee the acutely hazardous wastes while the State of Texas TECQ oversees the extremely hazardous wastes. These wastes are more hazardous than ordinary hazardous wastes. Examples include contaminated needles, Extremely hazardous wastes are wastes meeting any of the following:
If a waste generator has an extremely or acutely hazardous waste, there is a limit to the amount that they can store in the lab at one time. One quart of extremely or acutely hazardous waste can be stored before disposal is required. When one quart or more of extremely or acutely hazardous waste accumulates, the waste must be disposed of within three days of reaching that point. If less than one quart, you have 90 days to accumulate the waste
It is suggested that if you are accumulating a waste that falls into this category, you should dispose of it before it reaches the one quart limit. This way you will not have to be restricted by the three day maximum time limit.
For additional information on CESQG contact your campus Facilities Department or LSC OEM.
Responsibilities of Hazardous Waste Generators
Each laboratory person handling hazardous chemicals is responsible for the proper accumulation and management of waste in the laboratory.
Laboratory personnel are responsible for the:
