Spent caustic liquid
The caustic has been exhausted through use and no more specific form fits.
ComplyOnSiteWhere does Texas form code 109 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 109, then a class character. Form 109 describes a stream in the inorganic liquids category.
The form doesn't give a hazard status. The stream's makeup, source and properties decide the class character after it.
For a hazardous or Class 1 shipment on a Uniform Hazardous Waste Manifest, enter the full Texas code in Item 13, across 2 blocks on paper. Put any EPA waste codes beside it. The 3 form digits alone are not enough.
The generator sets the class from exclusions, federal hazardous-waste listings and characteristics, then Texas industrial-waste criteria. H means hazardous, and 1, 2 and 3 are nonhazardous industrial classes. Process knowledge or testing backs the decision. Picking a form doesn't set the class.
What does Texas form code 109 cover?
Caustic liquid that has been used up in a process. Record what the caustic was used for and why the discarded solution counts as spent.

Is spent caustic Texas form code 109 or 110?
| Code | When it fits |
|---|---|
| 109 | The caustic solution is spent from its process use. |
| 110 | The stream fits the caustic aqueous-waste description. |
| 106 | The caustic liquid holds metals and no cyanides. |
| 107 | The caustic liquid holds both metals and cyanides. |
| 108 | The caustic liquid holds cyanides and no metals. |
The sources name spent caustic and caustic aqueous waste separately, but don't say how to tell forms 109 and 110 apart.
Which wastes take Texas form code 109?
| Waste | When it’s 109 |
|---|---|
| Refinery spent caustic | Caustic used up in a refinery or chemical process. |
| Spent caustic cleaning solution | The caustic cleaning solution is spent. Unused or off-spec caustic aqueous liquid uses 110. |
