When to use 296
Organic liquids
Other organic liquids
Another organic liquid coolant with no more specific liquid form.
When to use 219

Form code 296 is for ethylene glycol coolant, and 219 for other organic liquid coolants such as propylene glycol.

Which Texas form code fits waste antifreeze?

Form	When it fits
296	The discarded liquid coolant is ethylene-glycol based.
219	Another organic liquid coolant with no more specific liquid form.

Household antifreeze can go to a local household collection or to a batteries, oil, paint and antifreeze (BOPA) collection or recycling route.

Business antifreeze needs a hazardous-waste determination, especially after solvent mixing or when it holds metals or has high pH.

Recycling alone doesn't create an exemption.

Class 1, 2 and 3 don't cover nonhazardous antifreeze from a nonindustrial repair shop.

Sewer disposal needs written approval from the treatment plant.

A form code doesn't give that approval.

Record the coolant formula and any contamination from use, including petroleum and metals.

Keep coolant apart from used oil and other liquids, and use petroleum classification where it applies.
