Cal. Code Regs. Tit. 22, div. 4.5, ch. 11, app XII - 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.
