Inorganic solids
Other dry ash, slag or thermal residue

Dry ash, slag or thermal residue not produced by waste incineration.

Dry ash, slag or thermal residue that did not come from waste incineration. Incinerator residue takes form 303.

Where does Texas form code 304 go in the Texas waste code?

In characters 5–7. The 8-character code is a 4-character stream sequence, then the 3-digit form 304, then a class character. Form 304 describes the stream in the inorganic solids category. It says nothing about hazard. The class character depends on what the stream is made of, where it came from and its properties.

For a hazardous or Class 1 shipment that needs a Uniform Hazardous Waste Manifest, enter the full Texas code in Item 13, across 2 blocks on paper. Add any EPA waste codes. The 3 form digits alone are not enough.

The generator sets the class. Work through the exclusions, then the federal hazardous-waste listings and characteristics, then the Texas industrial-waste criteria. H means hazardous. 1, 2 and 3 are nonhazardous industrial classes. Process knowledge or testing backs the class. Choosing a form doesn't set it.

What does Texas form code 304 cover?

Dry ash, slag or thermal residue from any source except waste incineration. Dry describes the form. The process that made it is what sets it apart from incinerator ash.

Is dry ash or slag Texas form code 304 or 303?

Code	When it fits
304	Dry residue from a thermal process other than waste incineration.
303	Nonpumpable ash, slag or residue from incinerating waste.
319	Any other inorganic solid that fits no named form. Specify it in Comments.

Record the thermal process and confirm it wasn't waste incineration. Looks alone can't tell these forms apart.

Which wastes take Texas form code 304?
