If you’ve received an informational notice from the California Department of Tax and Fee Administration (CDTFA) concerning an EPA ID number that you are unfamiliar with, you may have had a contractor working on your home or business that applied for the number on your behalf. Common reasons for this are hazardous waste generation during a cleanup or remodel, such as asbestos removal. 

This notice is sent to anyone who had an ID number issued in the last quarter to advise them that anyone who produces five or more tons of hazardous waste per calendar year is required to obtain a hazardous waste generator fee account number.

If you don’t currently generate five tons or more of hazardous waste per year, you may disregard this notice. 

If you would like to investigate further, you may look up the origin of the EPA ID number using the Hazardous Waste Tracking System (HWTS).
