Registering as a CESQG

You need a complete inventory of the hazardous waste you wish to dispose of at the time you register. Hazardous waste brought to the program must be described by at least the following: 
    1. Your company name, address, phone number and EPA ID #. 
    2. Estimate of how much hazardous waste is generated per month and per year at your
        business site. 
    3. Chemical name or trade name of the waste. 
    4. Percentages of chemical constituents in the waste. 
    5. Process generating waste and possible contaminants. 
    6. Size, type, weight, and number of containers to be brought in.

Material Safety Data Sheets (MSDS) are often your best source of information regarding the potentially hazardous products you use. An MSDS will list the hazardous constituents of each product. MSDS’s are available from product suppliers. If you have an MSDS for the hazardous product or waste you want to dispose of, have it handy when you call in to register and bring a copy with you on the day of the CESQG event.

If you do not have an MSDS for your hazardous product or waste, describe the waste’s characteristics, uses, and origin to the CESQG coordinator and mark this information on the product container. If the waste is still in its original container, keep it there because information on the container is likely to help with the waste description.

If the waste is not in its original container, label the container clearly with the chemical contents or bring the original container along with you. Unknown wastes cannot be accepted under this program, but may be resubmitted once a satisfactory description is available.
