California Hazardous Waste Codes
(a) Subdivisions (b) and (c) of this appendix establish the California Hazardous Waste Code Numbers assigned to wastes which have been identified as hazardous wastes pursuant to the characteristics of hazardous waste as set forth in article 3 of this chapter or pursuant to the lists of hazardous wastes in article 4 of this chapter. These Waste Code Numbers shall be used in complying with the notification requirements of Health and Safety Code section 25153.6 and, where applicable, in the recordkeeping and reporting requirements under chapters 12 through 15, 18, and 20 of this division.
(1) In cases where hazardous wastes may have both an EPA Hazardous Waste Number and a California Hazardous Waste Code Number, both numbers shall be used in complying with the notification requirements of Health and Safety Code section 25153.6 and the recordkeeping and reporting requirements under chapters 12 through 15, 18, and 20 of this division.
(2) If both a California Hazardous Waste Code from the “California Restricted Wastes” category and a code from another category of California Hazardous Waste Codes apply to a specific hazardous waste, the code from the “California Restricted Wastes” category shall be used.
