What is special waste?
- Is conditionally excluded state-only dangerous waste.
- Is solid only - not liquid, aqueous, or gaseous.
- Must be fully designated before it can be identified as special waste.
Options for managing special waste
Generators can manage special waste as fully regulated dangerous waste or they can choose to follow the conditional exclusion requirements. To take advantage of the conditional exclusion (in WAC 173-303-073), generators must do one or all of the following:
- Dispose of their waste in hazardous or municipal solid waste landfills.
- Recycle the waste on site or off site.
- Treat the waste in a way that is consistent with Ecology's treatment by generator guidance.
Examples of possible special wastes
- WSC2—Spent polymerization catalyst, sodium hydroxide and aluminum hydroxide, and batteries.
- WT02—Contaminated absorbents and debris, evaporator condensate, pollution control filter cake, and paint.
- WP02—Resins, adhesives, dried paint, sealant, grease, tar, metal machining wastes, and contaminated soil and absorbents.
