ComplyOnSiteWhere does Texas form code 502 go in the Texas waste code?
In characters 5–7. The 8-character code is a 4-character stream sequence, the 3-digit form 502 and a final class character. Form 502 puts the stream in the inorganic sludges category.
The form doesn't give a hazard status. The stream's makeup, source and properties decide the class character.
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 alongside 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. 1, 2 and 3 are the nonhazardous industrial classes. Testing or process knowledge supports that call, and picking a form doesn't set the class.
What does Texas form code 502 cover?
This form covers mostly inorganic, pumpable lime sludge that holds metals, and pumpable metal-hydroxide sludge. Metal-hydroxide sludge can fit even when lime wasn't part of the process.
