Cal. Code Regs. Tit. 22, § 66261.110 - Extremely Hazardous Waste Criteria

(a) A waste, or a material, is extremely hazardous if it:

(1) has an acute oral LD₅₀ less than or equal to 50 milligrams per kilogram; or

(2) has an acute dermal LD₅₀ less than or equal to 43 milligrams per kilogram; or

(3) has an acute inhalation LC₅₀ less than or equal to 100 parts per million as a gas or vapor; or

(4) contains any of the substances listed in section 66261.24(a)(7) at a single or combined concentration equal to or exceeding 0.1 percent by weight; or

(5) has been shown through experience or testing that human exposure to the waste or material may likely result in death, disabling personal injury or serious illness because of the carcinogenicity, high acute or chronic toxicity, bioaccumulative properties, or persistence in the environment of the waste or material; or

(6) is water-reactive.

(b) A waste containing one or more materials which are extremely hazardous according to any criterion of subsection (a)(1) or (a)(2) of this section is not extremely hazardous if the generator determines that neither the calculated acute oral toxicity nor the calculated acute dermal toxicity of the waste using the equation in section 66261.24(c) is numerically equal to or less than the toxicity limits prescribed in subsection (a)(1) or (a)(2) of this section and the waste is not extremely hazardous by any other criterion of this section.
