22 CCR App. XII

Where code 751 applies

California waste codes come from 22 CCR Division 4.5, Chapter 11, Appendix XII. A California code is required on the hazardous waste manifest for every load generated in or shipped into California — even for wastes that are hazardous only under California law and carry no federal code.

RCRA-regulated streams list a federal RCRA waste code on the manifest alongside code 751.

Where can a 751 stream go?

Recognized recovery routes for this waste family, ranked by typical recovery tier. Which route fits depends on your specific stream — composition, volume and region.

Metals recovery (HTMR / hydrometallurgical)

Medium recovery

Metal-bearing streams route to high temperature metals recovery or hydrometallurgical processing, where the contained metals are extracted and returned to commerce as secondary raw material.

40 CFR 268.42 Table 1 — HTMR technology standard

Specialist treatment below restriction thresholds

Specialist handling

California restricted wastes must be treated below the constituent thresholds before land disposal; treatment residues with metal value can continue to metals recovery.

40 CFR 268.40 — LDR treatment standards

These are the typical routes for california restricted wastes. Your stream's actual options depend on its composition and where it sits.
