  • Waste Disposal Authorization

    Information for contractors and consultants.

    Not sure if your waste can go to the landfill?

    We can help. We use the Waste Disposal Authorization (WDA) process to determine if waste is hazardous or non-hazardous so you can properly dispose in Pierce County.

    Some waste—like industrial waste or contaminated soil—can be dangerous and isn’t accepted at the landfill. Other examples include:

    • Contaminated soils.
    • Industrial waste (ash, slag).
    • Spent sandblast material.
    • Paint-booth filters.
    • Residue from steam-cleaning operations.
    • Grit and soil from carwash catch basins.
    • Certain asbestos waste.

    We will review the application within 3 business days and let you know if you can dispose in Pierce County. If accepted, we will issue the WDA. Conditions of approval vary.

    These Pierce County facilities accept waste through the WDA process:
