Current through Register 2024 Notice Reg. No. 12, March 22, 2024

The recordkeeping provisions of section 66264.73 specify that an owner or operator shall keep a written operating record at the facility. This appendix provides additional instructions for keeping portions of the operating record. See section 66264.73(b) for additional recordkeeping requirements.

The following information shall be recorded, as it becomes available, and maintained in the operating record until closure of the facility in the following manner: records of each hazardous waste received, transferred, treated, stored, or disposed of at the facility which include the following:

(1) a description by its common name and any applicable EPA Hazardous Waste Number or California Hazardous Waste Number from chapter 11 of this division which apply to the waste. The waste description also shall include the waste's physical form, i.e., liquid, sludge, solid, or contained gas. If the waste is not listed in chapter 11, article 4 or Appendix XII of this division, the description also shall include the process that produced it (for example, solid filter cake from production of ---, EPA Hazardous Waste Number W051).

Each hazardous waste listed in chapter 11, article 4, of this division, and each hazardous waste characteristic defined in chapter 11, article 3, of this division, has a four-digit EPA Hazardous Waste Number and/or a three-digit California Hazardous Waste Number assigned to it. This number shall be used for recordkeeping and reporting purposes. Where a hazardous waste contains more than one listed hazardous waste, or where more than one hazardous waste characteristic applies to the waste, the waste description shall include all applicable EPA and California Hazardous Waste Numbers;

(2) the estimated or manifest-reported weight, or volume and density, where applicable, in one of the units of measure specified in Table 1:
