California Environmental Protection Agency (Cal/EPA) Department of Toxic Substance Control Hazardous Waste Management Program
See national section for basic information and federal regulations.
Comparison: State vs. Federal
• Rules. The California Environmental Protection Agency (Cal/EPA) follows the federal rules for determining whether a waste exhibits a hazardous waste characteristic. See the national section CHARACTERISTIC WASTE for more information.
However, to determine the characteristics of corrosivity and toxicity, Cal/EPA has added state criteria to that required under the federal rules. For the corrosive characteristic, there are two more definitions. To determine the characteristic toxicity, Cal/EPA has added lists of inorganic and organic persistent and bioaccumulative toxic substances and their soluble threshold limit concentration. In sum, California regulates more substances as hazardous waste than the federal rules. See the state sections HAZWASTE DETERMINATION (CLASSIFICATION) and LISTED WASTES for additional guidance.
• Administration and enforcement. Cal/EPA's Department of Toxic Substance Control (DTSC) administers and enforces the rules for identifying characteristics of hazardous waste in California.
