Business Hazardous and Universal Waste

The IWMA has programs to help businesses manage their hazardous and universal waste.  State and Federal laws govern these programs and restrictions apply.

To dispose of hazardous waste, fill out the appropriate form below. If you qualify to participate in the program, the approved form will be emailed back to you with instructions to bring the inventoried waste to one of the following listed below.

Note: The IWMA is not a regulatory agency and cannot advise you regarding hazardous waste regulations or your current status as a Conditionally Exempt Small Quantity Generator (CESQG).  If you are unsure if the business is a CESQG or if you have questions about hazardous waste regulations, please call County Environmental Health at (805) 781-5544 for further information. The IWMA reserves the right to provide information to County Environmental Health to verify your compliance with CESQG regulations.
