The new Generator Improvement Rule (GIR) web page is now available, and will be used to disseminate information on DTSC's progress in implementing the GIR in CA.
DTSC issues interpretation letter concerning the regulatory status of spent desulfurization units.
What is a Generator?
A generator is any person, by site, whose act or process produces hazardous waste identified or listed in Chapter 11 of the hazardous waste regulations or whose act first causes a hazardous waste to become subject to regulation.
When determining if the generator regulations (Chapter 12 - Standards Applicable to Generators of Hazardous Waste) apply to you, there are 3 important terms used in the definition to consider:
Generators are responsible for properly characterizing (or identifying) all their hazardous wastes. The steps set forth to make such a determination are found in section 66262.11. Once a generator determines their waste meets the definition of a hazardous waste, the requirements that apply to them depends on the amount (or volume) generated. The following document, "Defining Hazardous Waste" is a good introduction to understanding how to make determinations on your waste.

In California, generators are divided into 2 categories:
If you have P-Listed hazardous waste, please read this 12/24/2015 letter regarding P-listed hazardous waste containers at California Healthcare Facilities.
Each type of generator must comply with its own set of requirements. For more information please see the Generator chart.
Does California have a conditional exemption for smaller quantity generators (i.e., generators of 100 kg or less of hazardous waste)?
No. California did not adopt the conditional exemption for smaller quantity generators in 40 CFR 261.5 including the counting requirements found in that section. Therefore, in California generators of 100 kg or less of hazardous waste per month are regulated as SQGs and not Conditionally Exempt Small Quantity Generators (CESQGs) as they would be under the federal hazardous waste management program.
Generators that periodically fall above or below their normal generation limit
If the amount of hazardous waste produced in a calendar month puts a generator in a different category, then they are responsible for complying with the applicable standards for that category of generator for that month (e.g., if a generator produces 500 kg of hazardous in June, they must comply with the SQG requirements but if they produce 1,200 kg of hazardous waste in the next month they must follow the LQG requirements). Generators who change status should consult with their CUPA.
A generator must count (i.e. must add up, or total) the entire quantity of hazardous waste is generates in a month, pursuant to section 66262.34 of Title 22, to determine their generator status for that month. Generally, most hazardous wastes are counted, however some are not.
The following are some examples of hazardous wastes that count towards generator status:
The following are examples of hazardous wastes that DO NOT count towards generator status:
