Which California codes cover metal-bearing waste?

Solutions, sludge, dust, machining waste and organic liquids with metals each have their own entry.

The codes are 121, 132, 171, 172, 342, 721, 722, 723, 724, 725, 726, 727, 728 and 792.

How do you tell California metal-bearing waste codes apart?

Record the test, the result and the units. Federal TCLP, California WET/STLC and TTLC test different criteria, and 723 specifically covers chromium(VI).

What can change the route for California metal-bearing waste?

Scrap-metal recycling exclusions can change the route. Hazardous sludge and fine powders don't become exempt scrap just because a recycler accepts them.
