(b) A waste containing one or more materials which are extremely toxic =12J to any criterion of paragraphs (a)(1) or (a)(2) of this section may be classified by the Department as not extremely hazardous if neither the calculated acute oral toxicity nor the calculated acute dermal toxicity of the waste using the equation in Section 66696(c) is numerically equal to or less than the toxicity limits prescribed in paragraphs (a)(1) or (a)(2) of this section and the waste is not extremely hazardous by any other criterion of this section.
